Description

Method for strengthening the foot of prefabricated lightweight wall and formwork system

Technical Field

The present invention relates to the technical field of construction engineering, and is particularly suitable for the preparation of prefabricated components that require protection of the bottoms of components such as wall panels. The present invention can greatly improve the anti-collision, waterproof, moisture-proof and erosion resistance of the feet of components such as walls, and discloses a method and a template system for strengthening the feet of prefabricated lightweight walls by spraying the surface of the template and adjusting the shape.

Background technique

Lightweight prefabricated wall panels are often used in construction projects. These wall panels use lightweight concrete or lightweight materials, and the material strength is relatively low. In addition, during the preparation of the wall, the corners of the wall mold are prone to bubbling and it is difficult to fully cast, which is a traditional process problem, which further weakens the edge strength of the wall. In addition, during the actual construction and use process, the wall panels, especially the feet, are prone to damage and corrosion. Therefore, it is usually necessary to strengthen the edges of the wall, especially the feet. The traditional method is to use angle steel to wrap the foot of the wall, but this type of edging material is separated from the prefabrication of the wall, and the subsequent edging process is complicated. The material is easy to deform during the edging process, which affects the accuracy of the wall assembly. In the later stage, the edging material is easy to separate from the wall and corrode and damage.

To this end, in view of the above-mentioned defects, the designers of the present invention have devoted themselves to research and design, and combined the experience and achievements of many years in related industries to research and design a method and formwork system for strengthening the foot of prefabricated lightweight walls to overcome the above-mentioned defects.

Through the wall foot stacking reinforcement method and the matching developed formwork system, the strengthening effect of the foot of the assembled wall panel is achieved simultaneously with the preparation of the wall panel surface layer in the integrated wall panel prefabrication process. This method overcomes the traditional process difficulty that the corners of the wall mold are not easy to be fully cast, effectively strengthens and protects the wall foot, and at the same time improves the efficiency and quality of wall panel production.

Cloth shaft, a spiral spring sheet mechanism is arranged between the two ends of the cloth rolling shaft and the side mold, the spiral spring sheet structure includes a spiral spring, when the side mold is in a horizontal position, the spiral spring sheet is in a tightened state, so that the cloth can be flattened to cover the junction area of the bottom mold and the side mold, after the casting material is cast on the cloth, when the side mold is rotated to a vertical position, the spiral spring sheet gradually relaxes, and the spread cloth is gradually retracted, the cloth rolling surface gradually becomes smaller, and the casting material on the cloth is gradually accumulated in the wall foot area, forming an effect of strengthening the wall panel foot.

Wherein: the telescopic cloth rolling structure includes a slurry blocking brush, which is composed of a high-density steel wire brush or a silicone brush and is arranged at the cloth rolling entrance and exit. When the side mold is flattened and the casting material is poured on it, the slurry blocking brush seals the cloth rolling entrance and exit to prevent the grouting material from leaking from the cloth rolling entrance and exit during pouring; as the side mold is adjusted from a horizontal posture to a vertical posture, the cloth rolling gradually returns to the inside of the cloth rolling entrance and exit, and casting material may remain on the cloth rolling. At this time, the slurry blocking brush can scrape off the residual casting material on the cloth rolling entering the cloth rolling entrance and exit.

Step 1: The template central control system sends a control command to the template posture control system. The template posture control system starts the mold shaft, driving the two side templates to a horizontal position. As the side templates are placed flat, the cloth on the cloth roll shaft is pulled out, and a section of the cloth roll casting area in the cloth roll and the side mold and the bottom frame in the bottom mold jointly form a casting area;

Step 2: The template central control system sends the pouring instruction to the slipform grouting coordination system, which issues a control instruction to pass the pouring material through the grouting port. At the same time, the template system moves on the slide rail so that the pouring material can be evenly poured in the pouring area. The pouring thickness detection system completes the thickness detection work from the pouring material, and the pouring thickness detection system sends the thickness detection information to the template central control system;

Step 5: After the temperature of the casting meets the preset first casting temperature, the template posture control system starts the mold shaft through instructions, driving the two side templates to adjust from a horizontal position to a vertical position. As the template is adjusted to a vertical position, the cloth on the cloth roll shaft is rolled back, and the cloth roll casting area gradually decreases to disappear.

The slurry sealing brush is composed of a high-density steel wire brush or a silicone brush or a silicone sealing strip, and is arranged on the lower side of the tangent edge between the bottom mold and the arc-shaped slide plate. When the side mold is flattened and the casting material is cast thereon, the slurry sealing brush seals the tangent area between the bottom mold and the edge of the arc-shaped slide plate to prevent the grouting material from flowing out of the edge tangent area during casting; as the side mold is adjusted from a horizontal position to a vertical position, the arc-shaped slide plate rotates tangentially along the edge of the bottom mold.

From the above content, it can be seen that the method and formwork system for strengthening the foot of a prefabricated lightweight wall of the present invention have the following effects:

1. The corner pouring of the wall and the wall panel facing layer are cast at the same time, which ensures the integrity of the wall corner and the wall from the forming stage, avoids the formation of gaps in the joint surface of the secondary process, and prevents the invasion of water vapor and corrosion. The mold rotation system and device are adopted to achieve uniform rotation of the template. At the same time, the facing layer materials in the corner area are effectively accumulated and squeezed, and the corner of the wall panel is strengthened, which effectively improves the anti-collision performance of the corner during assembly, and also improves the moisture and corrosion resistance of the corner during use.

2. Flatten the upper planes of the surface layer mold and the bottom mold to the same level to realize the integral casting of the wall surface layer and the bottom, then adjust the surface layer mold from horizontal to vertical, and adjust the angle between the surface layer mold plane and the upper plane of the bottom mold from 180° to 90°, so that the angle space between the surface layer mold plane and the upper plane of the bottom mold is compressed, and the concrete originally laid in the angle area is gradually accumulated as the angle space is compressed, and the residual air bubbles trapped in the corners are fully squeezed out. After solidification, the accumulated area is denser than other casting areas, thereby realizing the strengthening of the foot of the wall. This method of strengthening the foot of the wall by active accumulation overcomes the problem of difficult compaction of corner bubbles caused by traditional passive casting methods, and enables the surface layer and foot strengthening to be achieved simultaneously, which greatly improves the preparation efficiency of prefabricated wall panels.

3. A plate brush and a template washer are set on the outside of the corner area of the template. On the one hand, the template brush further prevents the loss of grouting materials, and on the other hand, it cooperates with the template washer to clean the surface of the template after demolding. For the arc area of the mold (the key position for achieving corner extrusion reinforcement), the mold's own extrusion type and the roll cloth replaceable type are adopted to meet different production needs.

The details of the present invention can be obtained from the following description and the accompanying drawings.

It coordinates with the grouting control system to issue control instructions for the spraying speed and amount of spraying; the pouring temperature detection system E, through the ambient temperature and the temperature of the pouring material, feeds back to the template central command control system, and the template central system calculates the relevant parameters and issues side mold rotation and demoulding control instructions to the template posture control system; demoulding self-cleaning system F, when the wall panel meets the demoulding requirements, the template center instructs the template posture control system to adjust the side mold state and transport the formed wall panel components away; then the template center instructs the template self-cleaning system to start, completes the cloth roll inlet and outlet and the flushing and cleaning of the template, and prepares a set of wall panel surface castings.

In this embodiment, referring to FIG. 4 and FIG. 5 at the same time, the main working process of the template system of the present invention is as follows:

The first step: the template central control system A sends a control instruction a to the template posture control system B. The template posture control system B starts the mold shaft 5 through the instruction b, driving the two side templates 6 to be in the horizontal position 23. As the side template 6 is placed flat, the cloth 9 on the cloth rolling shaft 3 is pulled out from the cloth rolling inlet and outlet 10 (one end of the cloth roll 9 is connected to the cloth rolling shaft 3, and the other end of the cloth roll is connected to the connection area 18 fixed to the bottom mold 2. When the side template 6 is placed flat, a section of the cloth rolling casting area 13 in the cloth roll 9 and the casting area formed by the side mold 6 and the bottom frame 1 in the bottom mold are placed flat. After the side template 6 is placed in place, the in-place instruction c is sent to the template posture control system B, and the template posture control system B stops the operation of the mold shaft 5 and sends the stopped operation instruction d to the template central control system A.

Step 2: The template central control system A sends the pouring instruction e to the sliding form grouting coordination system C, and the sliding form grouting coordination system C issues a control instruction f to pass the pouring material 7 through the grouting port 17. At the same time, the template system moves on the slide rail 14, so that the pouring material 7 can be evenly poured on the template system (specifically, the pouring area on the side template 6 in the horizontal position, the roll cloth pouring area 13 and the bottom frame 1 in the pre-cast bottom mold, and the short three-dimensional fiber mesh 8 has been pre-inserted on the bottom frame 1 to form an integral component). The moving speed of the template system on the slide rail 14 (according to the position of the grouting port, it can be selected to move from right to left, or it can be selected to move from left to right as shown in the figure) needs to be determined according to the grouting amount and grouting speed (specifically, during the pouring process, the pouring thickness detection system D completes the thickness detection work g from the pouring object 7, and the pouring thickness detection system D sends the thickness detection information h to the template central control system A.

Step 3: The formwork system moves and cycles through the formwork central control system A-operation instructions e-slipform grouting coordination system C-instructions f-formwork device-collection of thickness detection work g-sending detection information h until the pouring material completes the pouring of the entire pouring area.

Step 4: After pouring is completed, that is, when "condition 1" is met, the template central control system A sends a temperature measurement instruction i to the pouring temperature detection system E, and the pouring temperature detection system E starts to measure the temperature j of the pouring object 7, and the collected temperature information k is transmitted back to the pouring temperature detection system E; and the pouring temperature detection system E transmits the temperature information back to the template central control system A in real time until the temperature of the pouring object meets the preset first pouring temperature, that is, "condition 2" is met.

Step 5: After the temperature of the cast material meets the preset first casting temperature, the template central control system A sends the instruction m for adjusting the side mold angle to the template posture control system B; the template posture control system B starts the mold shaft 5 through the instruction n, driving the two side templates 6 to adjust from the horizontal position 23 to the vertical position 24. As the template 6 is adjusted to the vertical position 24, the cloth 9 on the cloth rolling shaft 3 is rolled back from the cloth rolling entrance and exit 10, and the cloth rolling casting area 13 gradually decreases to disappear. The casting material 7 on the cloth rolling casting area 13 is gradually accumulated and compacted in the foot area to form a foot reinforcement area 4. After the side mold 6 reaches the vertical position 24, the in-position instruction o is sent to the template posture control system B, that is, when "condition 3" is met, the template posture control system B stops the operation of the mold shaft 5 and sends the stopped operation instruction p to the template central control system A.

Step 6: The template central control system A sends a temperature measurement instruction i to the pouring temperature detection system E. The pouring temperature detection system E starts to measure the temperature j of the pouring object 7 and collects the temperature information k. It transmits it back to the pouring temperature detection system E. The pouring temperature detection system E transmits the temperature information back to the template central control system A in real time until the temperature of the pouring object meets the preset second pouring temperature, that is, "condition 4" is met.

Step 7: After the temperature of the pouring material meets the preset second pouring temperature, the template central control system A sends the instruction m for adjusting the side mold angle to the template posture control system B; the template posture control system B starts the mold shaft 5 through the instruction n, driving the two side templates 6 to adjust from the vertical position 24 to the horizontal position 23, and as the side templates 6 are placed flat, the cloth 9 on the cloth rolling shaft 3 is again pulled out from the cloth rolling inlet and outlet 10; after the side template device is placed flat in place, the in-place instruction o is sent to the template posture control system B, and the template posture control system B stops the operation of the template device and sends the stopped operation instruction p to the template central control system A, that is, "condition 5" is met.

Step 8: The template central control system A sends a cleaning instruction q to the demoulding self-cleaning system F, which starts the cleaner 11 to complete the template cleaning work r at the cloth roll inlet and outlet 10. When the cleaning work is completed, the cleaning completion instruction s is sent to the demoulding self-cleaning system F, and the stopped cleaning instruction t is sent to the template central control system A. The first round of wall panel surface structure is completed.

Step 9: Repeat steps 1 to 8 to complete the subsequent wall panel surface structure preparation work.

As shown in FIG. 3 , a second embodiment of the prefabricated lightweight wall footing reinforced formwork system of the present invention is shown.

The side mold 6 is used for surface layer casting, and a template shaft 5 is provided at one end thereof to realize movement between a horizontal position 23 and a vertical position 24 by rotating the template shaft 5. The bottom mold 2 is located between the two side molds 6, and its upper end is formed into a bottom frame 1 by preliminary casting, and when the surface layer is cast, the upper surface of the cast bottom frame 1 is used as the casting bottom surface of the wall foot reinforcement area. The template shaft 5 is provided with a driving device, which enables the side mold to rotate around the template shaft Adjusted from a horizontal position to a vertical position, the arc-shaped slide plate 19 extends as a whole from the foot of the side mold, and the arc-shaped slide plate is tangent to the edge of the bottom mold. The slurry sealing brush 21 is composed of a high-density wire brush or a silicone brush or a silicone sealing strip, and is arranged on the lower side of the tangent edge between the bottom mold 2 and the arc-shaped slide plate 19. When the side mold is flattened and the casting material is poured thereon, the slurry sealing brush 21 seals the tangent area between the bottom mold and the edge of the arc-shaped slide plate to prevent the grouting material from flowing out of the edge tangent area during pouring; as the side mold is adjusted from a horizontal position to a vertical position, the arc-shaped slide plate rotates tangent to the edge of the bottom mold. During the rotation process, the slurry sealing brush 21 continues to seal the casting material while scraping off any casting material that may remain on the arc-shaped slide plate that has passed through the tangent edge.

The template flusher 11 is connected to a water pump and a water pipe to further flush and clean the slurry sealing brush 21, the tangent area between the bottom mold 2 and the edge of the arc-shaped slide plate 19 after demoulding, and the surface of the arc-shaped slide plate 19.

Among them, the template system of the present invention also includes a control system, which mainly includes: a template central command control system A, which coordinates the parameter control commands between various systems according to the wall panel design requirements; a template posture control system B, which receives the template central control command and adjusts the template posture; a slipform grouting coordination system C, which receives the template central control command during the panel pouring process and moves the template at a uniform speed to ensure the control of the pouring amount and thickness; a pouring thickness detection system D, which measures the pouring thickness through laser ranging and feeds back to the template central command control system, and the template central system calculates the relevant parameters and performs the sliding form and grouting coordination. The slurry coordinated control system issues control instructions for the spraying speed and spraying amount; the pouring temperature detection system E, through the ambient temperature and the pouring material temperature, feeds back to the template central command control system, and the template central system calculates the relevant parameters and issues side mold rotation and demoulding control instructions to the template posture control system; demoulding self-cleaning system F, when the wall panel meets the demoulding requirements, the template center instructs the template posture control system to adjust the side mold state and transport the formed wall panel components away; then the template center instructs the template self-cleaning system to start, completes the flushing and cleaning of the arc slide entrance and exit and the template, and prepares for the next set of wall panel surface pouring.

In this embodiment, referring to FIG. 4 and FIG. 5 at the same time, the main working process of the template system of the present invention is as follows:

The first step: the template central control system A sends a control instruction a to the template posture control system B. The template posture control system B starts the mold shaft 5 through the instruction b, driving the two side templates 6 to be in the horizontal position 23. As the side templates 6 are placed flat, the arc-shaped slide area 19 is gradually extended to form a casting area together with the side mold 6 and the bottom frame 1 in the bottom mold. After the side template 6 is placed flat in place, the in-position instruction c is sent to the template posture control system B, and the template posture control system B stops the operation of the mold shaft 5 and sends the stopped operation instruction d to the template central control system A.

Step 2: The template central control system A sends the pouring instruction e to the slipform grouting coordination system C, which issues the control instruction f to pass the pouring material 7 through the grouting port 17. At the same time, the template system moves on the slide rail 14, so that the pouring material 7 can be evenly poured on the template system (specifically, the pouring area on the side template 6 in the horizontal position, the arc-shaped slide plate 19 and the bottom frame 1 in the pre-cast bottom mold, and the short three-dimensional fiber mesh 8 has been pre-inserted on the bottom frame 1 to form an integral component). The moving speed of the template system on the slide rail 14 (according to the position of the grouting port, it can be selected to move from right to left, or from left to right as shown in the figure) needs to be determined according to the grouting amount and grouting speed. Specifically, during the pouring process, the pouring thickness detection system D completes the thickness detection work g from the pouring object 7, and the pouring thickness detection system D sends the thickness detection information h to the template central control system A.

Step 3: The formwork system moves and cycles through the formwork central control system A-operation instructions e-slipform grouting coordination system C-instructions f-formwork device-collection of thickness detection work g-sending detection information h until the pouring material completes the pouring of the entire pouring area.

Step 4: After pouring is completed, that is, when "condition 1" is met, the template central control system A sends a temperature measurement instruction i to the pouring temperature detection system E, and the pouring temperature detection system E starts to measure the temperature j of the pouring object 7, and the collected temperature information k is transmitted back to the pouring temperature detection system E; and the pouring temperature detection system E transmits the temperature information back to the template central control system A in real time until the temperature of the pouring object meets the preset first pouring temperature, that is, "condition 2" is met.

Step 5: After the temperature of the cast material meets the preset first casting temperature, the template central control system A sends the instruction m for adjusting the side mold angle to the template posture control system B; the template posture control system B starts the mold shaft 5 through the instruction n, driving the two side templates 6 to adjust from the horizontal position 23 to the vertical position 24. As the template 6 is adjusted to the vertical position 24, the casting area of the arc-shaped slide plate 19 gradually decreases to disappear, and the casting material 7 on the arc-shaped slide plate 19 is gradually accumulated and compacted in the foot area to form a foot reinforcement area 4. After the side mold 6 reaches the vertical position 24, the in-position instruction o is sent to the template posture control system B, that is, when "condition 3" is met, the template posture control system B stops the operation of the mold shaft 5 and sends the stopped operation instruction p to the template central control system A.

Step 6: The template central control system A sends a temperature measurement instruction i to the pouring temperature detection system E. The pouring temperature detection system E starts to measure the temperature j of the pouring object 7 and collects the temperature information k. It transmits it back to the pouring temperature detection system E. The pouring temperature detection system E transmits the temperature information back to the template central control system A in real time until the temperature of the pouring object meets the preset second pouring temperature, that is, "condition 4" is met.

Step 7: After the temperature of the pouring material meets the preset second pouring temperature, the template central control system A sends the instruction m for adjusting the side mold angle to the template posture control system B; the template posture control system B starts the mold shaft 5 through the instruction n, driving the two side templates 6 to adjust from the vertical position 24 to the horizontal position 23, and as the side templates 6 are placed flat, the arc slide 19 is unfolded again; after the side template device is placed flat in place, the in-place instruction o is sent to the template posture control system B, and the template posture control system B stops the operation of the template device and sends the stopped operation instruction p to the template central control system A, that is, "condition 5" is met.

Step 8: The template central control system A sends a cleaning instruction q to the demoulding self-cleaning system F, which starts the cleaner 11 to complete the template cleaning work r after the joint where the arc-shaped slide plate and the bottom mold 2 are tangent. When the cleaning work is completed, the cleaning completion instruction s is sent to the demoulding self-cleaning system F, and the stopped cleaning instruction t is sent to the template central control system A. The first round of wall panel surface structure is completed.

Step 9: Repeat steps 1 to 8 to complete the subsequent wall panel surface structure preparation work.

It can be seen that the core principle of the method of the present invention is to compress the foot space of the wall panel mold to form a piled state for the casting material poured in this area, so that the residual air bubbles trapped in the corners are fully squeezed out, and the casting material is solidified to finally achieve the strengthening of the foot.

The present invention flattens the upper planes of the surface layer mold and the bottom mold at the same horizontal height to realize the integral casting of the surface layer and the bottom of the wall, and then adjusts the surface layer mold from horizontal to vertical, and adjusts the angle between the surface layer mold plane and the upper plane of the bottom mold from 180° to 90°, so that the angle space between the surface layer mold plane and the upper plane of the bottom mold is compressed, and the concrete originally laid in the angle area is gradually accumulated as the angle space is compressed, and the residual air bubbles trapped in the corners are fully squeezed out. After solidification, the accumulated area is denser than other casting areas, thereby realizing the strengthening of the foot of the wall. This method of strengthening the foot of the wall by active accumulation overcomes the problem that the corner bubbles are difficult to be dense due to the traditional passive casting method, and enables the surface layer and foot strengthening to be achieved simultaneously, which greatly improves the preparation efficiency of the assembled wall panels.
