Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a precast concrete plate (hereinafter referred to as a panel) such as a lightweight cellular concrete plate for a load-bearing wall in a building such as a house, an apartment, a condominium, and a school. It relates to the frame structure used.

[Conventional technology]

Conventionally, panels of unit width, such as lightweight cellular concrete boards, were joined together using shaped steel, and used as large panels for building walls. Japanese Patent Publication Nos. Sho 52-30769 and Sho 5
It is disclosed in JP-A-2-35206. These are mainly intended for middle- and high-rise buildings, in which shaped steel is fixed by bolts along the lower and upper ends of the panels, and assembled into large panels to improve workability in panel installation.

[Problems to be solved by the invention]

However, the above-mentioned invention is mainly intended for middle and high-rise buildings, and uses only large panels as non-bearing walls.

In addition, when concrete panels are used on the boundary walls of apartments, condominiums, schools, etc., the wall thickness required for sound insulation is larger than the wall thickness required for structural strength, and the horizontal resistance is more than necessary. It becomes a powerful concrete wall. Therefore, it is possible to provide sufficient horizontal rigidity and resistance even by dividing the concrete wall into a transportable piece and connecting it with a bending rigid steel section.

SUMMARY OF THE INVENTION The present invention provides an economical and easy-to-construction frame from the above-described viewpoint, while solving the problems of the prior art, while ensuring sufficient strength as the frame. .

[Means for solving the problem]

Hereinafter, an outline of the present invention will be described using reference numerals in the drawings corresponding to the embodiments.

The frame of the present invention is a frame composed of a main frame composed of a steel frame 12, a wall panel 2 composed of a precast concrete plate, and a panel 6 serving as a floor or a roof panel.
A plurality of wall panels 2 each having a height of two layers are erected vertically at positions parallel to the wife's side and the wife's side,
At the surface of the wall panel 2, a section steel 3 made of a channel steel or an angle is passed horizontally to the height of the floor or shingle 5, and the section steel 3 is bolted by two or more bolts 4 near both ends of each wall panel 2. The bearing wall is formed by being fixed to the wall panel 2.

In addition, the panel 6 constituting the floor or the roof panel 5 is supported by the shaped steel member 3 extending over the surface of the wall panel 2 and laid between the bearing walls, and the bearing walls on both sides of the bearing walls are excluded. Regarding the load-bearing wall position, the wall panel 2 is placed on the upper surface of the panel 6 on the floor.
Is laid to penetrate through, and concrete is cast thereon and integrated.

[Action]

When a wall 1 in which a plurality of wall panels 2 are connected by a shape steel 3 as shown in FIG. 6 receives a horizontal force, the wall 1 is deformed as shown in FIG. This is because the bending rigidity and the shearing rigidity of each of the precast concrete wall panels 2 are larger than those of the section steel 3 and move almost in the same manner as the rigid body rotation. As a result, the shaped steel 3 exerts a restraining effect between the bolts 4 of the adjacent wall panels 2 and integrates the entire wall 1.
Regarding the integration of the walls 1, connecting each wall panel 2 with a plurality of bolts 4 and reducing the bolt position interval between adjacent wall panels 2 increases the restraint of each wall panel 2, which is effective. It is.

Further, as shown in FIG. 9, it is easy to support the panel 6 constituting the floor or the shingle 5 on the shaped steel 3,
The wall 1 always bears the load of the panel 6.

Further, as shown in FIG. 5, at the load-bearing wall positions except for the load-bearing walls on both sides, a stress transmitting reinforcing bar 21 is laid on the upper surface of the floor panel 6 through the wall panel 2 and concrete is placed thereon. The casting is further integrated. In this case, the vertical load of the panel 6 is transmitted to the wall panel 2 via the stress transmitting reinforcing bar 21, and the concrete cast on the panel 6 is a floor portion composed of the stress transmitting reinforcing bar 21 and a precast concrete plate. Has the role of integrating the panel 6 with the panel 6.

Further, in the present invention, as shown in FIG. 3, the wall panel 2 uses a wall panel having a height of two layers, so that the wall on the first floor in the case of a wall panel having a height of one layer is used. There is no need for a vertical joint between the panel and the wall panel on the second floor, and even when horizontal force such as an earthquake is transmitted to the wall, the structure is such that stress can be easily transmitted directly from the second floor to the foundation. Furthermore, the two-layered long plate eliminates the joint, which is a weak point of the precast concrete panel structure, and can form a strong load-bearing wall through the first and second floors.

〔Example〕

 Next, the illustrated embodiment will be described.

FIG. 1 to FIG. 3 show an outline of how a wall panel and a panel of a floor or a shingle are assembled and an arrangement thereof in one embodiment of the present invention. The wall panels 2 each having a unit width of two layers and having a height of two layers are erected vertically at a plurality of positions parallel to the wife's side and the wife's side, and the height of the floor or roof panel 5 on the surface of the wall panel 2 The horizontally shaped steel bars 3 are fixed by bolts 4 near both side ends of each panel 2 to connect the panels 2 to each other.

The floor or shingle 5 in this embodiment, like the wall panel 2, is constituted by a long panel 6 having a unit width, and both longitudinal ends of the panel 6 are installed on the corresponding shaped steel members 3 of the load-bearing wall 1 facing each other. . Further, in this embodiment, the section steel 3 is attached to the floor of the panel 2 or the height of the shingle 5, a channel steel is used at the upper and lower ends, and an angle is used at the middle, and the flanges of the panel 6 are used at these flanges. The end is placed. In the figure, reference numeral 15 denotes a temporary beam serving also as a scaffold.

FIG. 4 shows an example of the connection between the top of the load-bearing wall 1 and the steel beam 16 perpendicular to the top when the partition wall enters the flat side. The steel beam 16 is bolted to the steel beam 16 via the plate 17 and the like that have been welded.

FIG. 5 shows an example of the connection of the lower end portion of the panel 2 at the intermediate load-bearing wall position excluding the both sides.
The lower end is covered with a mortar 18 on a foundation 11 and fitted and fixed to a channel steel 20 fixed by a hole-in anchor 19.
An angle as a section steel 3 for connecting the panels 2 in the lateral direction is fixed to both surfaces of the panels 2 by bolts 4 penetrating the panels 2, and a floor panel 6 is placed thereon.
In the figure, reference numeral 21 denotes a reinforcing bar for transmitting the stress penetrating the panel 2.

[Effect of the Invention] A plurality of wall panels made of precast concrete plates are arranged, and the shaped steel is fixed to the wall panel with two or more bolts near both side ends of each wall panel, so that the wall panel is formed by the shaped steel and the bolts. The steel wall bears horizontal force and can transmit in-plane shear stress. In this case, since the rigidity of the precast concrete panel is overwhelmingly large, the strength of the bearing wall is determined by the strength of the shaped steel.

The floor or shingle panel spanned between the load-bearing walls is directly supported and integrated with the shape steel bolted to the surface of the wall panel, especially for the floor panel.
On the upper surface, a reinforcing bar for stress transmission is laid by penetrating the wall panel of the middle load-bearing wall except for both wife's sides, and concrete is cast on it, increasing the integrity of the wall panel and floor, Stress transmission becomes smooth, and the proof stress of the frame structure is also improved.

The wall panel uses a panel having a height of two layers, and since there is no joint which is a weak point of the precast concrete panel structure between the first floor and the second floor, a strong load-bearing wall is provided through the first and second floors. It can be configured so that even when horizontal force such as an earthquake is transmitted to the wall, the stress is easily transmitted from the second floor directly to the foundation.

Since the assembly is performed by the dry method, no curing period is required, and the construction period can be shortened.

Since the panels are produced in a factory, variations in products can be prevented.

Since the shaped steel connecting the panels comes out of the plane, it can be used to support the floor or roof, and the workability is improved.

Panels, such as precast concrete boards, generally have sufficient axial force sharing capacity and can also serve as beams.
