Description

[Detailed description of the invention] [Technical field] FIELD OF THE INVENTION The present invention relates to connectors for unit buildings.

[Prior art] In general, a frame assembly consisting of a wall-type single beam in which structural panels 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. Compared to the construction method, external forces are supported evenly across the entire floor and wall, making it possible to obtain high structural strength.

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

When applying the above-mentioned wall construction method to a unit building, one building is divided into a plurality of building units consisting of wall panels erected on floor panels, and a roof unit joined to the top of each building unit. After each unit is produced in a factory, it is transported to a construction site and installed on a pre-prepared foundation.

By the way, in the installation work of the above-mentioned unit building, it is necessary to accurately position each wall panel of a plurality of building units at a predetermined butt angle state and to connect these wall panels reliably.

OBJECTS OF THE INVENTION The present invention accurately positions and aligns each wall panel of a plurality of building units in a predetermined abutment.

[Summary of the Invention] In order to achieve the above object, the present invention provides a connecting device for a unit building that connects each wall panel of a plurality of building units at a predetermined butt angle state, wherein the upper end of each wall panel A plurality of connecting parts are connected to each of the connected parts of the section, each connecting part is arranged at a predetermined butt angle state of each wall panel, and each connecting part is arranged along the longitudinal side of the corresponding wall panel. The length is at least twice the thickness of the corresponding wall panel.

[Structure of the Invention] FIGS. 9(A) to 9(C) are perspective views showing an example of the installation process of a unit building 1 to which the present invention is applied. 2 is a foundation, and on the top of the foundation 2, as shown in Fig. 9 (A), each lower floor building unit (3A to 3F) constituting the lower floor is installed.
are successively lowered by the hanging tool 4 and installed so as to face each other to form a lower floor building unit group. The upper part of this lower floor building unit group is shown in Figure 9 (
As shown in B), each upper floor building unit that constitutes the upper floor)
5 (5A to 5F) are successively suspended by the hanging tool 4 and placed against each other to form an upper floor building unit group.

In addition, the upper part of this upper floor building unit group is shown in Figure 9 (C
), each roof unit) 30 (30A to 30F) corresponding to each upper floor building unit 5 is mounted.

Each building unit 3.5 has a wall panel 7 erected on the side edge of the floor panel 6, as shown in FIG. The floor panel 6 is constructed as a floor structure by attaching a facing material 9 such as structural plywood or particle board to the upper surface of a floor framework assembled into a rectangular shape by joists 8, and each wall panel 7 has an upper frame 10, The load-bearing wall is constructed by attaching face materials 13 such as gypsum board or wood cement board to both the inside and outside of a wall framework assembled by a lower frame 11 and a vertical frame 12. In addition, the floor panel 6 is integrated with the lower part of the joist 8 by nailing a joint lower frame 14.

The joint bottom frame 14 provided on the floor panel 6 of the lower floor building unit 3 is connected to the anchor port 1 installed on the foundation 2.
- The joint bottom frame 14 provided on the floor panel 6 of the upper floor building unit 5 constitutes the wall panel 7 of the lower floor building unit 3.'' - The frame 10 and the bolts 16
are bound by. In addition, a joint lower frame 14A is integrated into the lower part of the roof unit 30 by nailing.
This joint lower frame 14A is tightly connected by the upper frame 10 forming the wall panel 7 of the upper floor building unit 5 and the pole 16A.

In this embodiment, the connection structure of each lower floor building unit 3 constituting the lower floor building unit group is as shown in FIG.

That is, the wall panels 7 of each lower floor building unit 3 that are butted against each other are connected to each other by using sheet metal connectors 17, 18, and 19 that are shaped according to the butt state of each wall panel 7. It is said that it is possible to connect to.

The wall panels 7A and 7B are butted against each other in the same straight line.
It is possible to connect. That is, the connecting tool 17 includes connecting portions 17A and 17B that are connected to connected portions 20A and 20B at the upper end of each wall panel 7A and 7B, respectively. Each connection part 17A, 17B of connection tool 17 is arranged on the same straight line, and the length along the long side of corresponding wall panel 7A, 7B of each connection part 17A, 17B is the corresponding wall panel 7A, It is set to be more than twice the thickness T of 7B. As a result, both wall panels 7A, 7B can be connected to the connecting parts 17A, 17B in a positioning state in which the connecting tool 17 is used as a ruler for connection, and their long sides are located parallel to the side sides of the connecting parts 17A, 17B. By nailing them to the connected parts 20A and 20B, they can be butt connected to each other on the same straight line.

As shown in FIGS. 4 and 5, the connector 18 is capable of connecting the wall panels 7C17D, which are juxtaposed to each other, and the other wall panels 7E, 7F, which are juxtaposed to each other, on the same straight line. According to Hayabusa, it is considered to be good.

That is, the connector 18 includes connection parts 18c to 18F that are connected to the connected parts 200 to 20F at the upper end of each wall panel 7c to 7F, respectively.
