Description

[Detailed description of the invention] [Technical field] The present invention relates to a unit building using the two-wall construction method.

[Prior Art] In general, there is a known wall construction method in which structural facing materials are attached to each frame of the floor and walls to form floor panels and wall panels, and these floor panels and wall panels are assembled into a box-shaped structure. According to this wall construction method, external forces are supported evenly across the entire floor and wall, making it possible to obtain high structural strength compared to the framework construction method consisting of columns and beams. .

Additionally, a unit building system is known as one method for increasing the industrial production rate of buildings.

When applying the iiQ wall type 1 method to a unit building, one building is divided into multiple building units consisting of wall panels erected on floor panels, and a roof connected to the top of each building unit. After dividing the building into units and producing each unit in a factory, the units are transported to the construction site and installed on a pre-prepared foundation.

Here, in a unit building using the conventional two-wall construction method, an upper floor building unit that constitutes an upper floor is installed in a part of the ceiling of a lower floor building unit or a group of lower floor building units that constitute a lower floor. In this case, at least the side edge of the floor panel of the upper floor building unit where the wall panel is erected is placed directly on the upper part of the wall panel of the lower floor building unit, and the upper floor building unit and the upper floor The load of the roof unit, especially the load of the wall panel, can be supported in a state where it is distributed to the corresponding wall panels of the lower floor building unit.

However, in a unit building using the conventional two-wall construction method described in 1., at least the side edge of the floor panel of the upper floor building unit where the wall panel is erected is attached to the lower floor building unit or the lower floor building unit group. The wall panel arrangement structure for the lower floor building unit or group of lower floor building units is constrained by the shape of the upper floor building unit and becomes complicated, making it difficult to configure the floor plan. , the degree of freedom in design is restricted.

[Object of the Invention] The present invention provides a solution to a partial area of the ceiling of a lower floor building unit or a lower floor building unit group without complicating the wall panel arrangement structure of the lower floor building unit or the lower floor building unit group. The purpose is to enable reliable installation of upper floor building units.

[Summary of the Invention] In order to achieve the above object, the unit building according to the wall type 1 method according to the present invention includes a reinforcing beam at one side edge of the floor panel of the upper floor building unit where the wall panel is erected. and placing both ends of one side edge of the floor panel reinforced by the reinforcing beams on top of mutually opposing wall panels of the lower floor building unit or the group of lower floor building units. This is what I did.
