Description

[Detailed description of the invention] This invention is designed to rationally and reliably cut the edges between columns and walls by attaching slit material to the edges of columns, especially in the construction of reinforced concrete or steel-framed reinforced concrete slit walls based on a new seismic design. This invention relates to a support for structural slit material for construction.

In the past, various methods and means for designing and constructing slit walls have been researched and partially disclosed through the introduction of new seismic design methods, but they are still lacking in practicality in terms of constructability or functionality. There is a problem with this.

In particular, the concrete pouring process has traditionally been carried out in the order of columns, descending walls, waist walls, etc., so the strong side pressure during concrete pouring at the columns allows elastic slit material to be inserted between the wall formwork. When the slit material is interposed in the construction, there is a drawback that the slit material may be deformed or moved.

Another method is to place a separator close to the wall of the slit material and use this to support the slit material, but this method has drawbacks such as poor workability near pillars and a significant reduction in work efficiency. There is.

This invention was devised in view of the above-mentioned drawbacks of the conventional art and to solve them.The structure of this invention will now be explained with reference to the drawings of the embodiments.

FIG. 1 is a perspective view of a support device showing a first embodiment, 1
3 is a locking piece with a hook-shaped hook part 2 formed on the upper part and extending vertically in a strip shape, and 3 and 3 are the locking pieces 1
The support rods are horizontally protruding parallel to each other from the upper and lower portions of the back surface of the support rod, and have male screw portions 3a, 3a formed at their tips.

4, 4 are male threaded portions 3a of the support rods 3, 3;
The upper and lower parts are integrally connected by a connecting rod 5 using an adjusting female threaded body screwed into 3a.

Reference numerals 6 and 6 denote slit supports, and a receiving plate 6b having an appropriate area is fixed to the tip of a male threaded shaft 6a that is screwed into the female adjustment threaded bodies 4, 4, so that it can move forward and backward with respect to the male threaded shaft 6a. It will be configured.

As shown in the plan view of the used state in FIG. Attach the formwork separator S to the area near the top of the screen and temporarily tighten it from the outside using the tightening metal fittings.

On the other hand, an elastic slit material B (elastite, sponge,
An elastic joint material mainly made of styrofoam, etc.) is inserted and supported, and the support is attached by hooking the upper hook part 2 of the locking piece 1 to the upper separator S, and the lower part is brought into contact with the lower separator S. ,
After locking, the slit supports 6, 6 can be adjusted as desired to abut and support one side of the slit material B.

In addition, concrete is poured as usual starting from the pillars, followed by the descending walls, waist walls, etc.
After curing, the formwork is dismantled, and the surfaces of the support pieces A and A where the slit material is installed are used as they are as joint material, and the ends of the separators S are treated with caulking or by being exposed.

According to the first embodiment of this invention as described above,
The slit material can be easily and easily attached to the column edge, and by installing the separator at an appropriate position near the column edge toward the wall, workability during formwork assembly is improved. Using a separator, the slit material can be supported simply and easily, and the distance between the slit material can be adjusted efficiently, arbitrarily, and freely by simple operations.
There is an effect.

FIG. 3 shows a perspective view of a second embodiment of this invention, in which the locking piece 21 for the separator,
21 are disposed in the left and right direction along the axis of the separator, and the locking pieces 21, 21
Support rods 23, 23 are provided on the back surface of the device, and are screwed into adjusting female screw bodies 24, 24 so as to be able to move forward and backward.

Furthermore, a slit support 26 having a receiving plate 26b having a suitable area fixed to the tip of a U-shaped male threaded shaft 26a is fixed to the other ends of the female threaded bodies 24, 24.

FIG. 4 is a partial side view of a third embodiment of this invention, in which a male screw 7 for tightening the separator is screwed from the front side to the back side of the hook-shaped hook portion 32 of the locking piece 31. The shape has the effect of making the attachment to the separator more reliable.

Furthermore, by narrowing the front side inward as shown by the chain line in the figure, it is possible to attach the separator relatively easily and reliably.

Note that the connecting rod 5 in the first embodiment can be omitted if another reinforcing means is selected, and in the second embodiment, the adjusting female screw body 24,
It is also possible to easily provide a connecting rod 25 for connecting 24.

Furthermore, in the first embodiment, a hook part like the upper hook part 2 can be integrally provided at the bottom of the locking piece 1 extending vertically to further secure and strengthen the installation. It can be inferred.

According to this invention as described above, it is not only possible to easily attach the slit material to the column edges in the construction of reinforced concrete structures or steel-framed reinforced concrete structures, but also it is possible to easily install separators placed at arbitrary intervals from the column edges. It can be used to reliably support the slit material, and the distance between the slit material can be freely and arbitrarily adjusted, and it can be provided as a support tool with excellent workability, and has an extremely large practical effect. be.
