Description

[Detailed Description of the Invention] This invention makes a part of the lightweight concrete plate a shear wall by combining a steel frame ramele and a lightweight concrete plate such as an ALC plate, and by selecting a connecting fitting between the lightweight concrete plate and the beam. This invention relates to a method of structurally planning and constructing a building so that the rigidity of the upper and lower floors approaches 1 and the eccentricity of the frame is reduced.

Conventionally, ALC boards have been used as wall boards in curtain wall structures, and the bearing capacity is designed to be borne by steel frame frames, trusses, and places. But AL
The C plate can also bear part of the horizontal load by devising the reinforcement arrangement or its attachment means.

On the other hand, if the earthquake-resistant elements, that is, the earthquake-resistant walls of a building are unevenly distributed, and the center of rigidity of the building differs from the point of force of inertia, torsional rotational vibration will occur and the earthquake resistance will decrease.

This invention was developed in view of the above-mentioned circumstances, and the wall plates are made of lightweight concrete wall plates such as ALC plates of the same type, and the joining fittings between the beams and the wall plates are selected, and the walls at the required positions function as earthquake-resistant walls. As a matter of course, the details will be explained below by referring to the illustrated embodiments.

A building constructed according to the present invention is constructed by a combination of a steel frame composed of steel columns 1 and steel beams 2 and lightweight concrete wall plates such as ALC plates, and the same or similar lightweight composite wall plates are used as the steel frame beams. 2, prepare two types of joining fittings 4a and 4b,
Lightweight concrete wall plates are used separately for a seismic wall 3a and a curtain wall 3b.

The joining fittings 4a used for the shear wall 3a are a pair of L-shaped steel plates 5 with ribs 6 on both sides, and the flanges on one side of the fittings 4a are attached to the steel beams 2. - A lower joint piece with a side flange attached to the seismic wall 3a is stacked with the other flanges and combined with bolts and nuts 7, and is provided at two locations each on the top and bottom of the seismic wall 3a.

The above-mentioned joint fittings 4a have a rigidity that allows stress transmission in small to medium earthquakes, but are deformed in large earthquakes and are designed to have a structure with a large energy absorption capacity.

The joining fittings 4b used for the curtain wall 3b are made by combining two L-shaped steel plates 5 with bolts and nuts 7, and the ribs 6 of the joining fittings 4a are omitted, and the mounting structure is similar to that of the earthquake-resistant wall. Same as in the case, but the joining metal fitting 4b
Its own deformation performance follows the deformation of the steel frame,
The curtain wall 3b does not bear the load acting on the building.

The metal fittings 4b used for the Naori-ten wall 3b may simply have the insertion holes 8 for the bolts 7 as loose holes.

By the way, in a multi-story building, for example, a three-story building, the horizontal load can be supported only by the steel frame on the top floor, so the curtain wall 3b may be used as the only curtain wall, and in some cases, the steel frame may be a modified frame.

This invention has the above-mentioned configuration, and allows lightweight concrete wall plates at predetermined positions to be made into earthquake-resistant walls by selecting joining fittings in order to bring the rigidity and eccentricity close to 1 in the structural plan of a building. Therefore, it is sufficient to prepare wallboards of a certain standard.

In addition, lightweight concrete wall plates such as ALC plates, which were conventionally used as curtain walls, can be used together with steel frames to bear the horizontal force, and can also be used as earthquake-resistant walls according to the horizontal force burden on each floor, and the top floor is made up of steel frame frames. The horizontal force can be borne by the structure alone and the diagonal line effect can be dealt with, allowing an economical and rational design.
