Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a formwork panel in which formwork members used when pouring concrete are interconnected with a predetermined formwork connector.

[0002]

[Prior art]

 When building a reinforced concrete structure, generally, the formwork is sequentially built from the part where the reinforcement has been completed, and the concrete is filled into it, but there is a defect in the formwork design or assembly. If so, the formwork may collapse during concrete driving, leading to unexpected accidents.

Therefore, when designing the formwork, it is necessary to fully consider the load during concrete construction, the lateral pressure of the concrete, etc. Especially, when the casting height is large, it is commensurate with the lateral pressure of concrete. At the same time as selecting a formwork having sufficient strength, these formwork must be connected with a predetermined strength.

As a formwork material suitable when the concrete lateral pressure is large, there is a metal formwork member called metal foam.

The metal form member is composed of a dam plate that comes into contact with concrete and ribs that reinforce the dam plate, and they are connected to each other using a connecting tool 11 shown in FIG. It can be assembled as.

The connecting tool 11 is formed by connecting two legs 12 and 13 which are substantially parallel and opposite to each other with a predetermined crossover 14 to form a substantially U-shape, and the ends of the legs 12 are formed inward at a substantially right angle. It is bent to form a rotary shaft 15.

In order to connect the form members, as shown in FIG. 6, first, the two form members 1 are made to be adjacent to each other and the ribs 3 are brought into contact with each other, and then the rotary shaft 15 is attached to the form members. The fitting 11 is fitted in the hole 16 provided in the rib 3 and the connecting tool 11 is straddled over the two ribs 3 and is hammered in the direction of the arrow.

Then, the connecting tool 11 rotates about the rotating shaft 15, and the two ribs 3 are forcibly sandwiched in the U-shaped gap of the connecting tool 11 and strongly crimped to each other. 1 is firmly connected as a formwork panel.

The formwork panel thus formed is built in a predetermined concrete pouring position.

Next, a fastening bolt such as a foam tie is used to maintain the distance between the facing dam plates, and a square pipe or the like is attached to the back surface of the formwork panel to prepare for lateral pressure during concrete pouring.

Next, concrete is poured, and after curing for a predetermined period of time, the connector 11 is removed from the rib 3 and the form panel is disassembled.

[0012]

[Problems to be solved by the device]

 However, if the connecting tool is completely driven into the ribs, it will be difficult to remove it during dismantling, i.e., the ribs and the dam will not be able to shake the hammer sufficiently or will be accidentally Since the ribs are struck, when attaching the connecting tool, in consideration of workability at the time of removal, there were cases in which the work was stopped while the connecting tool was not fully driven and was slightly lifted from the rib.

[0013] Such a situation causes a reduction in the attachment strength between the form members, and in the worst case, causes the form panel to collapse during concrete pouring.

Further, there is also a problem that the ribs are erroneously hit to deform the ribs, so that the form member cannot be diverted sufficiently.

The present invention has been made in consideration of the above-mentioned circumstances, and is a form panel capable of increasing the connection strength between form members by improving the workability of removing the form connector. The purpose is to provide.

[0016]

[Means for Solving the Problems]

 In order to achieve the above object, the formwork panel of the present invention comprises, as described in claim 1, two or more formwork members in which a predetermined reinforcing member is erected on the back surface of a predetermined dam plate and along the outer periphery thereof. And two legs that are substantially parallel and opposite to each other are connected by a predetermined crossover to form a U-shape as a whole, and the ends of the legs are bent inward at a substantially right angle to form a rotary shaft. And a connecting member for a mold having a protrusion for attachment and detachment, and the rotating shaft of the connecting member for the mold is fitted into the holes formed in each of the reinforcing members abutting each other. The two or more formwork members are connected to each other by sandwiching the reinforcing member between the legs of the formwork connecting tool.

Further, in the formwork panel of the present invention, the attaching / detaching projections are substantially perpendicular to the formwork member when the crossover of claim 1 is in contact with the edge of the reinforcing member. As described above, the attachment angle of the detachable protrusion is adjusted.

Further, the form panel of the present invention is obtained by bending the middle of the leg of claim 1 at a predetermined angle.

Further, in the form panel of the present invention, the barrier plate of claim 1 is made of a resin material, and the reinforcing member is made of metal.

Further, in the form panel of the present invention, as described in claim 5, a reinforcing member made of an aluminum material is erected on the back surface of the barrier plate made of a predetermined resin material and along the outer periphery thereof. Two or more formwork members, short legs and long legs bent at a predetermined angle are connected by a predetermined crossover to form an overall U-shape, and the ends of the long legs are inwardly formed at a substantially right angle. It is bent to form a rotation shaft, and a detachable projection is further provided on the bridge so that the detachable projection is substantially attached to the mold member in a state where the bridge is in contact with the edge of the reinforcing member. And a connecting member for a mold in which the mounting angle of the attaching / detaching projection is adjusted so as to be vertical, and the rotation axis of the connecting member for the form is connected to each of the reinforcing members abutted against each other. It fits into the drilled hole and the reinforcement is applied between the short leg and the long leg. The two or more formwork members are connected to each other by sandwiching the members.

[0021]

[Action]

 In order to assemble the formwork panel of the present invention, first, the two formwork members are made adjacent to each other and their reinforcing members are brought into contact with each other. Next, the formwork connector is straddled over the two reinforcing members with the rotary shaft of the formwork connector fitted in the hole provided in the reinforcing member.

Next, the attachment / detachment projections provided on the formwork connector are hammered into the reinforcing member to firmly connect the adjacent formwork members.

Next, in order to disassemble the formwork panel of the present invention, the reverse procedure described above is performed, that is, the attachment / detachment projections are hit with a hammer from the opposite direction, and the formwork connector is reinforced with the formwork member reinforcement member. Remove from.

Here, when attaching and detaching the formwork connector, the place to be hit with the hammer is not the connector body as in the conventional case, but the attachment / detachment protrusion at the position protruding from this, so it is erroneous. It is possible to mount and dismount the formwork connector accurately and easily without hitting the ribs.

Further, if the legs are bent in the middle, the reinforcing member can be more securely tightened by the formwork connecting tool, and the formwork members can be firmly connected to each other.

EXAMPLES Examples of the formwork panel of the present invention will be described below with reference to the accompanying drawings. It should be noted that parts and the like which are substantially the same as those of the conventional art are designated by the same reference numerals and the description thereof will be omitted.

(First Embodiment) FIG. 1 is a perspective view of a mold member 1 and a mold connector 21 which form the mold panel of this embodiment, in (a) and (b), respectively. Is.

As can be seen from the figure, the formwork member 1 of the present embodiment has ribs 3 standing upright on the back surface of the dam plate 2 that comes into contact with concrete and along the outer periphery thereof. 3 is provided with a hole 16.

The mold member 1 is preferably made of, for example, metal, and particularly preferably made of lightweight metal such as aluminum.

The formwork connector 21 of the present embodiment is formed into a substantially U-shape by connecting the legs 12 as long legs and the legs 13 as short legs with a crossover 14 to form an overall U-shape. , Legs 13 are approximately parallel and in opposite positions.

The gap between the leg 12 and the leg 13 is a rib so that a predetermined restoring force acts as a force to tighten the rib 3 when the two ribs 3 are forcibly press-fitted to widen the gap. A value slightly smaller than twice the thickness of 3 is recommended.

The ends of the legs 12 are bent inward at a substantially right angle to form a rotary shaft 15, and when the rotary shaft 15 is fitted into a hole 16 provided in the rib 3 of the formwork member 1, the rotary shaft 15 is rotated. The formwork connector 21 is rotatable about the shaft 15.

The formwork connector 21 of this embodiment is further provided with an attachment / detachment protrusion 26 in the vicinity of the crossover 14.

FIG. 2 is a side view showing a state in which the formwork connector 21 is completely driven into the rib 3.

As can be seen from the figure, the attachment / detachment protrusion 26 is provided when the formwork connector 21 is completely driven into the rib 3, in other words, in a state where the bridge 14 is in contact with the rib 3. It is preferable to adjust the mounting angle so that the rib 3 of the formwork member 1 extends substantially perpendicularly.

That is, when the distance from the upper end of the rib 3 to the upper end of the hole 16 is represented by D and the inner distance to the transition 14 and the rotating shaft 15 is represented by L, the attachment angle α of the attachment / detachment protrusion 26 (the transition 14 And the angle with respect to the plane including the rotation axis 15) is preferably set to cos α = D / L.

Further, as can be seen in the figure, in order to secure the tightening of the rib 3 by the leg 12 and the leg 13, the intermediate portion of the leg 12 is bent at a predetermined angle β.

FIG. 3 is a perspective view showing a state in which two formwork members 1 are connected using the formwork connector 21 and assembled as a formwork panel.

As can be seen in the figure, in order to assemble a mold panel using the mold member 1 and the mold connector 21 of this embodiment, first, two mold members 1 are placed adjacent to each other to form ribs. 3, and then the rotary shaft 15 is fitted into the hole 16 provided in the rib 3 of the mold member 1 to straddle the mold connector 21 between the two ribs 3.

Next, the attachment / detachment projection 26 is hit with a hammer to drive the formwork connector 21 into the rib 3 to firmly connect the adjacent formwork members 1 to each other.

Next, in order to disassemble the assembled form panel, the reverse procedure described above is performed, that is, the attachment / detachment projection 26 is hit with a hammer from the opposite direction (the direction of the arrow in FIG. 3), and the form connector 21 Can be removed from the rib 3.

Here, when attaching and detaching the formwork connector 21, the place to be hit with a hammer is not the connector body as in the conventional case, but the attachment / detachment projection 26 at a position protruding from this.

Therefore, it is possible to accurately and easily attach and detach the formwork connector 21 without accidentally hitting the rib 3.

In particular, when the formwork connecting tool is driven into the rib, conventionally, in consideration of workability of removing the formwork connecting tool, the attachment has not been sufficiently performed. With the formwork connector, it is now possible to easily remove the formwork connector by hitting the attachment / detachment protrusion with the hammer in the opposite direction.Therefore, when attaching the formwork connector, Can be sufficiently driven into the rib.

As described above, by facilitating the removal of the formwork connector, the connection strength of the formwork members can be dramatically increased.

In addition, there is no risk that the ribs will be struck and deformed by mistake, and the number of diversions of the mold can be increased to improve the economical efficiency.

Second Example Next, a second example will be described. It should be noted that parts and the like that are substantially the same as those of the prior art or the above-described embodiment are designated by the same reference numerals, and description thereof will be omitted.

FIG. 4 is a perspective view showing the formwork member 31 constituting the formwork panel of the second embodiment.

In the formwork member 31 of the present embodiment, a dam plate 32 that comes into contact with concrete is formed of a resin material, and ribs 3 as a reinforcing member are erected on the back surface thereof and along the outer periphery thereof. A hole 16 is provided in the rib 3. Further, a rib 33 for supplementing the rigidity of the dam plate 32 is provided on the back surface of the dam plate 32.

The ribs 3 and 33 are preferably made of metal, particularly lightweight metal such as aluminum.

The formwork member 31 can be similarly connected by using the formwork connector 21 described above, and the action and effect thereof are substantially the same as those of the first embodiment. Then, its detailed description is omitted.
