DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite structure of a wall and a beam floor.

[0002]

2. Description of the Related Art In a large wall structure having a wall thickness of 35 to 50 cm, when a span exceeds 6 m, a ready-made half PC plate cannot be used, and conventionally, a ribbed slab or a hollow slab was generally used.

[0003]

However, hollow slabs and ribbed slabs have a large slab thickness and beam structure.
Weight increases. In addition, the amount of construction has increased, and shortages of craftsmen have caused problems in quality, construction period, and construction cost. The present invention has been proposed in view of the problems of the prior art described above, and the object thereof is to save labor, reduce the weight of the building, structurally improve the workability, and improve the workability. It is to provide a combined structure of a wall and a beam floor.

[0004]

In order to achieve the above object, a composite wall and beam floor structure according to the present invention has a wall thickness of 35 cm.
An end of a girder made of a single piece of H-section steel having an anchoring portion processed is fixed to a concrete load-bearing wall of about 50 cm to 50 cm, and floor concrete is cast on a formwork mounted on the girder. Wall and beam floor composite structure, wherein the anchoring unit is:
At the boundary with the concrete load-bearing wall, a vertical plate welded between the upper flange and the lower flange,
And an L-shaped piece welded to the upper surface of the upper flange and the lower surface of the lower flange.

[0005]

That is, the feature of the present invention is that the end of the girder on which the anchoring portion including the vertical plate and the L-shaped piece is welded at the boundary with the concrete bearing wall having a wall thickness of 35 cm to 50 cm. Is fixed to the concrete bearing wall,
It has a wall and beam floor composite structure in which floor concrete is cast on a formwork mounted on a girder. Therefore, according to the present invention, while arranging reinforcing bars and formwork on site,
A wall and beam floor composite structure having sufficient strength and rigidity and reduced beam thickness and slab thickness can be formed.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. A is a concrete bearing wall having a large wall thickness, 1 is a vertical streak of the bearing wall A, and 2 is a horizontal streak. B is a girder and H-section steel 3
End plates 4 are welded to the left and right free ends, respectively, and a vertical plate 5 is welded between the upper and lower flanges at the boundary with the load-bearing wall A.
At the same time, the upper and lower L-shaped pieces 6 sandwiching the respective flanges are welded, and the end face plate 4, the vertical plate 5, and the upper and lower L-shaped pieces 6 constitute a fixing portion for the load-bearing wall A.

[0007] The opposite ends of the girders B made of H-shaped steel are fixed to the bearing walls A facing each other, and a minimum formwork such as a keystone plate C is mounted on the upper flange of the girders B made of the H-shaped steel. Pour concrete D on the keystone plate C.

[0008]

According to the present invention, the wall thickness is from 35 cm to 5 cm.
The end of the girder on which the anchoring portion including the vertical plate and the L-shaped piece welded at the boundary with the concrete bearing wall of 0 cm was fixed to the concrete bearing wall, and mounted on the girder. Floor concrete is cast on a formwork such as a keystone plate. By reducing the slab thickness, it becomes possible to construct a composite wall and beam floor structure in which the weight of the building is reduced. In addition, since it includes formwork such as girder and keystone plate, supporting members such as pipe supports are not required, which leads to securing work space under the slab, shortening the construction period,
In turn, this will help reduce construction costs.
