Description

[Detailed description of the invention] This invention relates to a joint structure between an outer wall and a floor.

Various demands are being made on modern houses in accordance with the times, such as improved fire resistance, earthquake resistance, and durability, as well as energy saving and sound insulation. Against this background, in recent years, various housing construction materials have been developed and improved in order to meet the various requirements mentioned above. In addition to this, walls made of lightweight aerated concrete are actually used in some areas.

When applying the above-mentioned lightweight aerated concrete walls to buildings, especially residences, conventionally the so-called curtain wall specifications, in which no load is applied, are used.
Alternatively, there are many specifications in which a wall is attached between the steel frame members to form one unit, and the vertical load is borne by the steel frame frame, and the horizontal load is borne by the steel frame frame and the wall.

This idea differs from the above-mentioned conventional technology in that it attempts to use lightweight aerated concrete walls as they are as load-bearing walls.In particular, the upper and lower exterior walls and the floor are connected using special connecting fittings, bolts, and joints. It is an object of the present invention to provide a joint structure between an external wall and a floor, which has high joining accuracy and easy assembly, and also has high strength against loads, by joining the external wall and the floor with the members.

This invention will be explained below with reference to the drawings.
