Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit and a roof unit by a wall type construction method, and more particularly to a building unit and a roof unit which can contribute to simplification of ceiling installation work at a construction site.

[0002]

2. Description of the Related Art Generally, a wall type construction method is known in which a structural panel is struck on each frame of a floor and a wall to form a floor panel and a wall panel, and the floor panel and the wall panel are assembled into a box-shaped structure. . According to this wall type construction method, an external force is evenly supported on the entire floor and the entire wall, and high structural strength can be obtained, as compared with the case of the frame construction method consisting of columns and beams. . A unit building method is known as one method for increasing the industrial production rate of a building. When applying the above wall-type construction method to a unit building, one building is divided into a plurality of building units in which wall panels are erected on floor panels and a roof unit joined to the top of each building unit. After division and production of each unit in the factory, these units will be transported to the construction site and installed on a pre-prepared foundation. That is, first, the building unit for the lower floor is installed on the foundation to form the lower floor of the building, and then, on the upper part of the installed lower floor building unit,
A building unit for the upper floor is installed to form the upper floor of the building, and a roof unit of a corresponding size and shape is installed on top of the installed upper floor building unit.

By the way, conventionally, for example, Japanese Patent Publication Sho 58
As described in Japanese Patent Publication No. 30978, etc., the work of fixing a building unit to a foundation, joining upper and lower building units, joining a building unit and a roof unit together, and strengthening the mutual tightness are facilitated. For the base,
A splicing bottom frame called a head tie is used. FIG. 7 shows a joint structure of a conventional unit building. As shown in this figure, a base 1a and a head joint 1b are installed on a floor along a side edge of a floor frame on the back side of the floor panels 2a and 2b in a factory in advance. The side joists 3 are in a state of projecting more toward the inside of the floor framework than the side joists 3a and 3b and the end joists that form the outer frame of the framework.
It is attached to a, 3b and edge joists. Further, the head joint 1c constitutes the lowermost part of the roof unit C. When the unit is installed, the building unit A is fixed to the foundation D by fastening the base 1a with anchor bolts. Further, the building unit B on the upper floor is fastened to the building unit A on the lower floor by fastening the head joint 1b and the upper frame 6a of the wall panel 5a on the lower floor with the fastening bolts 4a, and further, the roof unit C is By fastening the head joint 1c and the upper frame 6b of the upper floor wall panel 5b with the fastening bolts 4b, the head unit 1c is tightly connected to the upper floor building unit B.

After the installation of all the units is completed as described above, the ceiling mounting work is performed. This ceiling installation work is, for example, a common specification document for frame construction wall construction (18
Page 7: Published by the Japan Housing Finance Association, 1991 edition)), etc., and a plurality of field bridges 7 that define the ceiling part between a pair of facing head ties 7
, And the field edges 8, 8, ... On the lower surface of the field edge bridge 7 that was erected.
, And the ceiling panels 9a and 9b are attached to the lower surfaces of the fields 8, 8 ,.

[0005]

[Problems to be Solved by the Invention] However, in the past,
The head joints 1b and 1c are made of the same material as the upper frames 6a and 6b of the wall panels 5a and 5b, that is, the dimension type 204.
Since a JAS standard material (thickness 38 mm, width 89 mm) (hereinafter referred to as 204 material) was used, during head mounting, as shown in the figure, the head joints 1b and 1c were connected.
The outermost edges 8b and 8c along the head are connected to the heads 1b and 1c.
It was necessary to arrange it so that it abuts against. This is because the ceiling surface materials 9a and 9b cannot be attached to the side edges of the ceiling portion without a field edge that abuts the head ties 1b and 1c. Therefore, when viewed as a unit building as a whole, the number of field rims to be installed is large, which may complicate the ceiling installation work on site.

The present invention has been made in view of the above circumstances, and provides a building unit and a roof unit capable of further increasing the industrial production rate of a building and alleviating the complexity of the ceiling mounting work on site. The purpose is to do.

[0007]

In order to solve the above-mentioned problems, the building unit according to claim 1 has at least one side edge of a floor panel in which joists are assembled to form a floor framework, A wall panel in which an upper frame, a lower frame, and a vertical frame are assembled to form a wall frame is erected, and a head joint is attached to the back side of the floor panel, and is attached to the joist along the side edge of the floor panel. In the building unit for the upper floor, the head joint is wider than the upper surface of the wall panel on the lower floor to which the head joint is to be placed and tightly bound when assembling the unit building, and It is characterized in that it is formed so as to project to the inside of the wall panel of the lower floor, and that the ceiling surface material of the lower floor can be attached to the lower surface of the inward projecting portion of the head joint.

Further, in the building unit according to claim 2, the floor panel has face members attached to the upper surface of the floor frame, and the wall panel has face members attached to the inside and the outside of the wall frame. It is characterized by

Furthermore, the roof unit according to claim 3 is a roof unit in which a roof panel is attached to the upper surface of a roof frame having a head joint at the lowermost portion, wherein the head joint is used when assembling a unit building. Is formed so as to be wider than the upper surface of the wall panel of the building unit on which the head tie is to be placed and tightly bound, and to project inward of the wall panel, and the inner projecting portion of the head tie is A ceiling surface material can be attached to the lower surface.

[0010]

According to the structure of the present invention, the head tie is wider than the upper surface of the wall panel and projects into the wall panel. Therefore, the inwardly projecting portion of the head tie can function as a field rim, so that it is possible to omit attaching the field rim to the head tie. For this reason, it is possible to alleviate the complexity of the ceiling installation work at the site,
The work period can be shortened.
