Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to reinforced concrete construction or steel-frame reinforced concrete construction based on a new seismic design, and in the past, various methods and means have been researched for this type of slit material through the introduction and construction of new seismic design methods. Although it is partially disclosed,
Regarding construction, it is still not very practical.

In particular, regarding the concrete pouring process, from the pillar to the lower wall,
Because it is often constructed in the order of waist walls, the strong lateral pressure during concrete pouring at the pillars has the drawback that elastic slit materials can cause deformation or movement of the slit materials. .

The present invention has been made in view of the above-mentioned drawbacks of the conventional art, and is intended to solve the problems.Next, the structure of the invention will be explained with reference to the drawings of the embodiments.

FIG. 1 is a perspective view showing the first embodiment, FIG. 2 is a plan view, and FIG. 3 is a partial side view.

1 is a thin plate-like slit support plate having the required width and length, and it is preferable to use a piping plate, metal lath, etc. to improve adhesion to concrete.

2.2--tt- With support legs arranged and fixed in parallel at required positions above and below on one side of this slit support plate 10,
It is formed by bending a round bar into a mountain shape.

Reference numeral 3.3 denotes a mounting bolt fixedly disposed on the tip end surface of each pair of support legs 2.2--1.

As shown in FIG. 4, the support device according to the first embodiment consists of a slit tie (elastic tie 1) formed to a desired size on one side of a slit support plate l, an elastic material mainly made of sponge, styrofoam, etc. Advantages) Place A in the column form P1 and wall form P2 in a state where it is fixed by adhesive or other suitable means.

Furthermore, the mounting bolt 3.3 is inserted between the wall formwork 22 with removable formwork receiving pieces B, B screwed on both sides thereof, and then tightened from the outer surface with N and N to form a sliver. ) +7 A is attached to a predetermined position in the column recess.

In addition, during concrete pouring work, remove the formwork support pieces B and B from the ends of the columns and mounting bolts 3.3, and remove the joint bars M and treat each with mortar or caulking. It is.

Note that the forms of the formwork receiving pieces B, B and the joint rods M may be embedded in the concrete 1.

Additionally, the slit material may be applied after the slit support plate has been attached to the wall formwork.

According to the first embodiment with the above-mentioned structure, it is possible to easily and reliably attach the Surin 1 material to the column depression, and the deformation of the slit due to concrete pouring into the column formwork can be avoided. There is no need to worry about moving.

FIG. 5 is a plan view showing the second embodiment, in which the longitudinal side edge of the slit support plate 21 is bent to one side to form a reinforcing piece 21a, which has a sufficient reinforcing effect against concrete lateral pressure. It is something to play.

FIG. 6 is a plan view showing the third embodiment, in which protruding lips 81a bulging to one side are formed on both sides of the inner side p along the longitudinal direction of the slit support plate 31. As in the second embodiment, it has a sufficient reinforcing effect against concrete 1 and lateral pressure.

In any of the first to third embodiments, the support leg 2 is not limited to a round rod shape, but may also be a plate shape or a single leg with a thick wire diameter.

Further, the support leg 2 and the mounting bolt 3 may be attached to one place near the center of the slit support plate 1 as long as the lower end of the slit support plate 1 is fixed on the slab.

FIG. 7 is a partial perspective view showing the fourth embodiment, in which a mounting bolt/I/1/43 is directly fixed to one side of a slit support plate 41, and the central part is shaped like a U-shape in plan. By forming it by bending, there is no need for supporting legs as in the above embodiment, and the bottom cost can be reduced.

Furthermore, depending on how the wall formwork P2 is assembled, it is also possible to directly fasten a linear mounting bolt to one side of the support plate and to approach the recess of the column formwork P1 and fix the mounting bolt.

FIG. 8 is a perspective view of the main parts of the fifth embodiment, showing claw pieces 51a-m-
It can be easily joined by pressing the slit material A against the slit support plate 51.

Note that the mounting bolts 3 may also be used as separators for tightening the formwork, and the treatment of the ends of the wall formwork after dismantling may be selected as necessary.

=5- According to this invention as described above, reinforced concrete construction,
In addition, slit material can be easily and reliably installed in column depressions in steel-framed reinforced concrete structures, and the slit material does not deform or move when concrete is poured into the column formwork, improving reliability for new seismic designs. is high, and the practical effect is great.
