Description

Detailed Description of the Invention (Industrial Application Field) The present invention aligns reinforcing materials parallel to the side plates of the formwork with high precision in a formwork for producing ALO (autoclave-cured lightweight aerated concrete). The present invention relates to an ALO reinforcement fixing device for

(Problems of the prior art to be solved by the invention) In general, ALO raw materials are injected into a formwork in which reinforcing materials are arranged to produce semi-plastic concrete blocks, which are then cut with piano wire and then placed in an autoclave at high temperature. ALO panels are manufactured by curing. The market for ALO panels has been rapidly expanding in recent years due to their high strength, light weight, heat insulation properties, and ease of construction. The reinforcement material is this person I
Since the JO panel is made of cement, it is inserted to increase its weak tensile strength.・This reinforcing material is
During the ALO panel manufacturing process, if the reinforcing material is not aligned in the correct position in the mortar after hardening, although it is aligned in the formwork before or after pouring the raw material into the formwork,
When cutting a mortar block, the reinforcing material hits the cutting blade and damages the cutting tool, and the reinforcing material is exposed on the surface of the ALO panel, damaging its appearance.

Furthermore, if reinforcements are not inserted at predetermined positions within the ALO panel, the calculated strength will not be achieved, which is a serious consequence. Therefore, after manufacturing the semi-plastic concrete block, it is important that the semi-plastic concrete block is accurately placed at a predetermined position within the block.

By the way, conventionally, as shown in FIG.
The reinforcing material 1 is suspended by suspending the fixing jig 21, supporting the reinforcing material 1 by the corresponding fixing jig 2I of each set frame 5, and placing the set frame 3 across the formwork side plates 4. Formwork 18
The fixing jigs 21 are also suspended within the formwork 18. For this reason, the reinforcing material is pushed by the injection pressure of the raw material or the foaming pressure of the foaming agent in the raw material and is inevitably moved from its fixed position in the formwork.

Therefore, in order to fix the position of the reinforcing material when placed in the formwork, (1) increase the thickness of the fixing jig. ■One possible method is to make a blind hole in the bottom plate of the form and insert the tip of a chisel into it.

However, in method (2), the diameter of the hole formed in the product increases when the jig is removed after manufacturing the semi-plastic concrete block, and the strength of the product decreases. Method ■ cannot be used unless the position of the jig is determined, and it requires a lot of effort to clean the hole and insert the jig into the hole. It is also possible to predict the movement of the reinforcing material due to injection or foaming, and shift the position of the reinforcing material in advance so that it will be placed in a predetermined position due to that movement, but this method does not allow the reinforcing material to maintain its position. This method is complicated, and it is inevitable that the position of the reinforcing material within the product cannot be precisely controlled.

(Object of the Invention) The present invention was devised to solve the above-mentioned conventional problems, and it is possible to fix the position of the reinforcing material in the formwork with high precision regardless of the raw material injection pressure or foaming pressure. The purpose is to

(Structure of the Invention) The ALO reinforcing material fixing device of the present invention suspends a fixing jig for supporting a reinforcing material from a set frame, and straddles the set frame between the side plates of the form. The fixture shall have the elasticity to extend or contract to be longer or shorter than the distance between the set frame and the bottom plate of the formwork, and shall have an extension force, and the extension force of the fixing jig will cause the lower end of the jig to be attached to the formwork. The press is fixed to the bottom plate.

(Example) An example of the present invention will be described below with reference to FIGS. 2 to 4.

As shown in FIG. 2, the apparatus of the present invention is constructed by suspending a fixture 2 for supporting a reinforcing material 1 from a set frame 3, and straddling the set frame 3 between side plates 4 of the form.

The fixing jig 2 may be any material as long as it has elasticity to extend or contract longer or shorter than the distance between the set frame 6 and the formwork bottom plate 5, and has an elongating force, and its specific structure is not limited. without limitation.

An example of such a fixing jig 2 will be explained from FIG. 3 and FIG. 4. In the figure, 6 is a cylindrical upper member;
A handle 7 is fixedly attached to the upper end of the handle 7 and one screw hole 8 is drilled therein. A stopper 9 is attached to the handle 7, and a spring receiving bolt 10 for adjusting the pressing force of the spring is screwed into the screw hole 8. Also, a hexagonal hole is drilled at the tip of the pole 10 for rotating the pole 10 with a hex wrench. Reference numeral 11 denotes a cylindrical lower member, and a spring guide 12 and a fixed shaft 14 having a reinforcing member support fitting 13 are fixed to the upper and lower ends of the lower member 11. Furthermore, a long hole 15 is formed in the upper end of the lower member 11 along the longitudinal direction of the lower member 11. The upper end portion of the lower member 11 is slidably fitted into the upper member 6, and a sliding pin 16 that engages with the elongated hole 15 provided in the lower member 11 is attached to the upper member 6. , attached to the upper member 6 through the screw hole 8 ) 10
A compression spring 17 is interposed between the lower member 11 and the lower member 11 .

In this way, the compression spring 17 automatically extends the sliding bottle 16 until it touches one end of the slotted hole 15, and also allows it to be shortened against the spring until the sliding bottle 16 hits the other end of the slotted hole 15. , the upper and lower members 6 and 11 are configured to be able to rotate together.

In the apparatus of the present invention, the fixing jig 2 is fixed to the set frame 3 by attaching the handle 7 to the set frame 9 as shown in FIG.
By fixing it to the set frame 3, the lower end of the jig (the tip of the fixed shaft 14) is pressed against the formwork bottom plate 5 by the extension force (force of the compression spring 17) of the fixing jig 2. Thus, the fixing jig 2 is supported at both ends by the form bottom plate 5 and the set frame 5. The fixing jig 2 is inserted therethrough, and the reinforcing material 1 supported by the reinforcing material supporting metal fittings 13 is disposed within the formwork 18.

The method for hanging the fixing jig 2 to the set frame 3 was to insert it into the set frame 3 and fix the handle 7 of the set frame 31ζ with the fastener 9.
Alternatively, the upper end of the fixing jig 2 may be fitted and fixed from the lateral direction.

In addition, the method of supporting the reinforcing material 1 by the fixing jig 2 was to insert the fixing jig 2 into the reinforcing material 1 and to support it by the reinforcing material support fitting 15 of the fixing jig 2, but for example, The reinforcing material 1 may be hooked onto the fixing jig 2, or the like.

Further, the extension force of the fixing jig 2 is obtained by the compression spring 17 due to its low cost and ease of maintenance, but it may also be obtained by, for example, air pressure, oil pressure, repulsive force of the same magnetic poles of magnets, etc. The lower end of the jig (the tip of the fixed shaft 14) is the formwork bottom plate 5
The force applied is obtained by the stretching force of the fixing jig 2, and can be adjusted by the spring force adjustment screw mechanisms 8 and 10 provided on the fixing jig 2. The fixing jig 1 is installed so that it can resist the force that sometimes acts through the reinforcing material 1.
It is preferable that the weight is 10 kg or more, and the weight is 25 Ic9 or less per fixing jig so that the fixing jig 2 can be easily placed in the formwork 18. The tip of the fixing jig 2 may be lost, but in order to effectively prevent lateral displacement during injection of raw materials and foaming, it is preferable to form it in a plane perpendicular to the longitudinal direction of the jig.0 (Effects of the Invention) As described above, since the present invention has a structure in which the fixture for supporting the reinforcing material is fixed in the formwork with both ends supported by the set frame and the bottom plate of the formwork, when the raw material is injected into the formwork and foamed, The reinforcing material can be reliably held in place within the formwork against the forces exerted on it. Therefore, the reinforcing material can be placed in the center of the product with high accuracy, ensuring the strength and quality of the product.

Incidentally, in the present invention, when a spring clamp is attached to the lower end of the fixing jig 2 and it is pulled horizontally, the tensile force at the moment when the lower end of the jig starts to slide on the formwork bottom plate 5 is 0.7/i-f.
When the force of the compression spring 17 is adjusted so that
As shown in the table below, there was a significant improvement over the conventional device.
