Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for assembling and disassembling a mold frame. More specifically, the present invention relates to a mold frame assembly and disassembly device in concrete mold construction work.

[Conventional technology]

Traditionally, wood or metal molds have been selectively used for forming poured concrete, but assembly and
Applying a mold stripping agent, inspecting, dismantling, organizing, etc. requires a lot of manpower and time, and the mold can remain in place for as long as 4 weeks after concrete is poured until it hardens, and mold assembly is difficult. Because of the structure of molds, they cannot be left alone and reused until their shelf life has expired, which limits the reuse rate, which places a heavy burden on mold construction contractors and indirectly delays the construction period. This is the reason why the construction work is not progressing.

Therefore, in recent years metal form (Metal
Although metal forms have been used to some extent to shorten the construction period and improve the quality of poured concrete, metal forms do not deviate from the scope of wood-type frames, and assembly and disassembly equipment are the same and slightly different from those of wood, and in the end, mold panels must be peeled laterally from the molding surface from the inside of the concrete molded body, just like wood panels, so the use of mold frames is still limited, and mold Problems with the construction work still remain. Of course, in order to shorten the construction period, methods are used to promote hardening by conducting heat through the metal frame, but this is not a good method as it reduces the strength of the concrete.

The prefabricated construction method is being widely adopted in Japan and Europe to shorten the construction period, but not only is it expensive to transport the prefabricated parts, but it also has to be mass-produced on-site to save on labor costs. Standardization is a prerequisite, and for this purpose modules must also be established. In other words, despite the advantages of this construction method, the design of these components has become uniform, and conventional mold construction still plays an important role in adapting to the desired size and shape.

[Problem that the invention seeks to solve]

The present invention has been proposed to overcome the above-mentioned disadvantages and deficiencies. In other words, its main purpose is to tension the inner frame panel of a concrete wall molding during assembly, release the tension during disassembly, and allow it to be peeled off along the molded surface, thereby simplifying and speeding up construction work. Assembling mold frames that can shorten the construction period even for buildings of any design,
Our goal is to provide demolition equipment.

The inner panel 1 is hooked onto the hook 413 attached to the upper part and lifted while moving upward and rearward, and is slid along the sliding slot 411 of the guide bar 42, thereby releasing the tensioned inner panel 1 and causing it to contract inwardly. Since a gap G (see FIG. 3) is created between the inner panel 1 and the concrete surface, the inner panel 1 is easily peeled off along the concrete surface due to this gap G. Of course, the screws were already strengthened before disassembly.

It is advantageous if the lifting device uses a hydraulic cylinder instead of a crane, as shown in FIG. That is, the wedge body 41 is moved by a hydraulic cylinder P having one end pivoted to a plate b riveted to the wedge body 41 and the other end pivoted to a plate a riveted to the lower end of the wedge member 43. It is pulled upwards and backwards.

Figure 11 shows the inner panel 1 assembled and the wedge body 4

In addition, in this embodiment, the wedge main body 41 of the first embodiment described above is inserted into the wedge-shaped groove by a force transmission mechanism, and removed from the groove by a lift device. Instead of doing this separately, the wedge body is moved by interlocking engagement between the worm and the worm gear, so that insertion into and removal from the wedge-shaped groove can be performed by the same mechanism.

That is, in FIGS. 12 to 16, the reference numeral 10

The suspension operation of the suspension device 6 and the tightening operation of the lower conical fitting 5 are performed in tandem. First, the screws 54 of the conical fitting 5 are temporarily tightened, and the first suspension part 16 and the second suspension part 27 is engaged by inserting the protrusion 161 into the through hole 271 of the engagement arm 270 and tightening the screw, adjust and tighten the screw 54 to fix the mold frame upright on the conical metal fitting 5 on the floor. let

Note that the present invention is not limited to rectangular walls, and if the size of the panel 1 is devised, the second
It goes without saying that this method can also be applied to the polygonal buildings shown in Figures 4 and 25.

(Effects of the invention) Since the mold frame demolition of the present invention has been changed from the conventional horizontal direction to the vertical direction, the construction method has also changed accordingly, and the conventional floor and the supporting wall below it were constructed together. However, in the present invention, on the contrary, the floor and the wall above it are constructed together, which not only makes it convenient to transport the mold frame, but also allows the construction of the floor and the wall above it at the same time. Since the inner mold frame is dismantled at this stage, not only can the mold frame be reused, but other parts of the mold frame can also be peeled off earlier than the specified retention period (i.e., the retention period using conventional construction methods). This reduces the construction period. However, since the mold frame is mechanically peeled off vertically by a crane and the panel assembly itself is lifted and transported to the upper layer or the necessary location together with the cutting device, the mold frame can be reassembled quickly.
This not only shortens the construction period, but also saves the cost of mold frame work, which in turn reduces the overall construction cost.
