Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a room unit constituting a room portion of a unit building by a wall type construction method, and is particularly suitable for application to an upper floor portion when a lower floor portion of the unit building is a hall. is there.

[0002]

2. Description of the Related Art Generally, a wall-type construction method is known in which a structural panel is attached to each frame of a floor and a wall to form a floor panel or a wall panel (bearing wall), and the floor panel and the wall panel are assembled into a box-shaped structure. Has been. According to this wall type construction method, an external force is evenly supported on the entire floor and the entire wall, as compared with the case of the frame construction method consisting of columns and beams, and high structural strength can be obtained. . A unit building method is known as one method for increasing the industrial production rate of buildings such as houses.

When the above wall type construction method is applied to a unit building, for example, as described in Japanese Patent Laid-Open No. 55-152236, a single building is installed with a floor panel and a wall panel erected. It is divided into a plurality of room units and a roof unit that is joined to the top of each room unit, each unit is produced in the factory, then these units are transported to the construction site, and the It will be installed. And in such a unit building, it is common to match the size of each room on the upper floor and the lower floor, and in this case, the wall of the lower floor is located directly above the wall panel of the lower room unit. By arranging the wall panel of the upper-floor room unit along the panel, the high structural strength of the wall construction method can be maintained without any trouble.

However, in recent years, room layouts have become diversified, and a large room tends to be desired. For example, in FIG.
In some cases, a hall is formed on the lower floor, and a plurality of small rooms or rooms and a balcony are formed adjacent to each other on the upper floor, as shown in FIG. In such a case, conventionally, a floor beam of high beam is attached to the end joist of the floor panel of each room unit constituting the upper floor to support the floor panel. That is, as shown in the figure, when two room units 2 and 3 are installed adjacent to each other directly above a lower-floor room unit (hereinafter referred to as a hall unit) 1 forming a hall, the room unit 2
The floor panel 2a along the edge joist not shown in the joint between the floor panel 2a of the room unit 3 and the floor panel 3a of the room unit 3,
Floor beams 4 and 5 each having a beam height of 3a or more are attached respectively, and thereby, the room unit 2 and the room unit 3 are attached.
We try to avoid the disadvantage in structural strength due to the absence of the wall panel on the lower floor just below the joint with.

[0005]

However, in the above-mentioned conventional room unit, in the case of installing a plurality of rooms or the like directly above the lower floor hall, the floor beams 4 and 5 having high beam formation are used as floors. Since it projects above the upper surfaces of the panels 2a and 3a, a step 6 is formed between the panel and the adjacent room, which is particularly inconvenient for elderly housing. As means for eliminating such a stepped portion 6, the floor panel 2a,
It is conceivable that a face material is further attached to the upper surface of 3a, but this is not necessarily appropriate because it causes an increase in material volume and man-hours.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to directly move to and from an adjacent room directly above the lower floor hall without straddling a step portion, and to reduce the number of construction steps. The purpose is to provide a room unit for the upper floor that can.

[0007]

In order to solve the above-mentioned problems, in the room unit according to claim 1, a pair of floor panels are arranged in parallel with each other with the web material sandwiched vertically. And a plurality of long wooden composite joists made of the flange material of at least one wall panel are provided on the wide surface portion of the floor panel and along a direction orthogonal to the longitudinal direction of the composite joists. It is characterized by being installed upright.

A room unit according to a second aspect of the invention is characterized in that it is an upper-floor room unit installed directly above the lower-floor hall unit.

[0009]

According to the structure of the present invention, since the I-type composite joists that are strong against bending stress are used, the floor joists can be made longer than before. Therefore, it can be installed directly above the lower floor hall unit. In addition to this, FIG.
As shown in, on the wide surface part (non-side edge part) of the upper floor panel,
If the load bearing wall 30c is provided in the direction orthogonal to the I-shaped composite joist, high structural strength can be maintained, so that it is possible to integrally configure a plurality of rooms and the like. That is, in the conventional configuration in which a plurality of room units are joined, as shown in FIG. 3, the load applied from the load bearing walls 2b and 3b must be received by the wall panel 1b of the hall unit 1, and therefore, Floor beams 4 and 5 with high beam strength are required. On the other hand, according to the configuration of the above invention, the load of the load bearing wall 30c itself and the load applied to the load bearing wall 30c are I-type composite joists 21 and 2.
Since the pair of wall panels 90a, 90a of the hall unit 40 (FIG. 2) on the lower floor are supported via 1, 1, ... The stepped portion between them can be eliminated. In addition, since a plurality of room units can be integrally manufactured in advance by improvement, the industrial production rate can be improved and the number of on-site construction steps can be reduced.
