[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork fitting for assembling a formwork for placing concrete.

[0002]

2. Description of the Related Art In general, the manner of shaking of a building partially varies depending on the size, structure, shape, foundation condition of the ground, and the like, and as a result, the building may be destroyed. In order to prevent the destruction of the building due to the fluctuation of the shaking, there is a so-called expansion joint construction method in which the building is separated and constructed.

[0003] By the way, in the expansion joint portion of a building, in particular, since the gap between the walls is narrow, when these walls are simultaneously cast into concrete or when the concrete is cast close to an existing building, Conventionally, an intervening material such as a heat insulating material is interposed between the two walls to bury them.

[0004] However, the insertion or burying of the inclusions makes it impossible to reuse the inclusions, which not only increases the material cost, but also causes the inclusions to not actually cut the edges at the expansion joint. There were problems such as becoming.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems. The purpose of the present invention is to ensure that the formwork can be reliably and stably even between narrow walls. It is an object of the present invention to provide a metal mold for a formwork, which can hold and hold the material, and can surely collect and reuse the material.

[0006]

Means for Solving the Problems The metal mold for formwork of the present invention is:
A separator mounting bolt having a head and a female thread for the separator, a nut screwed into the male screw of the bolt and tightening and fixing the bolt with the outer form panel sandwiched between the head and the nut; A separator that is screwed and connected to a female screw formed on the bolt, surrounds the separator, separates the concrete from concrete, and holds the outer form panel and the inner form panel at predetermined intervals; and the separator. And a clamp for fixing the inner formwork panel to the formwork clamping rod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an outer form panel, and a hole 1a formed at an appropriate position is
As shown in the enlarged view, the separator mounting bolt 2 is inserted and fastened and fixed by the nut 3.

As is clear from FIG. 3, the separator mounting bolt 2 has a male screw 2a screwed with the female screw 3a of the nut 3, and a tapered surface 2c is formed on the outer peripheral surface of the head 2b. The guide is guided so that an end of a separate pipe 6, which will be described later, can be accurately fitted to the head 2b. A female screw 2d for a separator is formed at the center of the bolt on the side of the head 2b.

In FIG. 2, reference numeral 4 denotes a side pressure supporting plate, which is a single tube which is heavy and wide by being fixed by tightening with the bolts 2 and the nuts 3 in a state of being superposed on the outer surface of the outer form panel 1. It has a function as a substitute for

Referring again to FIG. 1, reference numeral 5 denotes a separator, and a male screw 5a formed at the tip of the separator is screwed into the female screw 2d of the separator bolt 2 for connection. (See FIG. 2) Around the separator 5, a separate pipe 6 made of a PVC pipe or the like is extrapolated to prevent concrete from flowing around the separator 5.

Reference numeral 8 denotes a form-tightening rod, which is connected to the separator 5 through a cone 9 and has a clamp 10
The vertical single pipe 12 and the horizontal single pipe 13 are fixed by the tightening nut 11.

As described above, as shown in FIG. 4, two concrete wall forms having a narrow interval are assembled. In addition, as shown in FIG. 5, a tube 14 for inflating the interior by injecting air therein may be inserted between both outer form panels 1, 1 to support the lateral pressure. In this case, the plate 4 may be omitted.

[0013]

As a metal fitting for attaching the separator 5 to the outer form panel 1, a head 2b and a female screw 2d for the separator are used.
Between the separator mounting bolt 2 and the male screw 2a of the bolt 2 and the head 2b.
And a nut 3 for tightening and fixing the bolt 2 in a state where it is sandwiched, so that it can be mounted quickly and securely without using any cross bar or nail, and also has a wall thickness that does not require a cross bar. Even when a thick panel or a metal pier is used, there is an advantage that it can be attached without any trouble.
