FIELD OF THE INVENTION The present invention relates to a building unit used as a component of a unit building.

[0002]

BACKGROUND ART Building unit 8 that constitutes a unit-type building
1 is a pillar 81A that is erected in four corners as shown in FIG.
The frame has a frame structure of a ramen structure including a lower beam 82 and an upper beam 83, which are large beams bridged between the upper ends and the lower ends of these columns, and has four upper beams 83 and lower beams. Among the two upper beams 83 and the lower beam 82 that are opposed to each other on the longer sides of the two 82, a plurality of ceiling beams and floor materials, which are internal construction materials, are fixed by nailing. Wooden beams 84 (ceiling beams) and 85 (floor joists) are bridged. Then, in order to prevent structural deformation of the building or to prevent deformation of the unit during truck transportation from the factory to the construction site, two braces 87 are provided on the diagonal of the square frame surrounded by the four upper beams 83. By arranging in an X shape, the building unit was reinforced.

[0003]

However, with the diversification of building designs in recent years, the types of building units have become diverse, and in particular, from the viewpoint of securing a large living room space, each of the four lower beams of the frame member is used. Of the upper beam 82 and the upper beam 83, the need has arisen for a unit in which two beams facing each other have a longer length.

When producing such a long building unit, a load such as a load, seismic force, wind pressure, etc. acts on the building unit, so that it must have sufficient strength against such a load. I won't. Here, if the material specifications of the pillar 81A, the lower beam 82, and the upper beam 83 that form the building unit are changed in order to increase the strength of the building unit, the cost of the member increases and the member in the building unit production increases. This will lead to complicated management.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems. It is an object of the present invention to provide a building unit having a sufficiently large structural strength without causing an extreme increase in member cost by performing simple reinforcement.

[0006]

The building unit of the present invention has a frame formed by including two girders facing each other, and a wooden structure for fixing a planar internal work material between the girders. In a building unit in which a beam is bridged, a reinforcing beam made of metal is bridged between the two girders.

In the above, the shape of the metal reinforcing beam is
Angle steel, flat steel, groove steel, etc. may be used, and square steel pipe may be used.

The wooden beam and the metal reinforcing beam may be arranged separately or may be integrated.

When the wooden beam and the metal reinforcing beam are integrated, the integrated beam may be a wooden beam fixed to the side surface or the lower surface of the metal reinforcing beam, but it is a metal reinforcing beam. It is also possible to use an integrated beam in which the horizontal pieces of the angle members of the book are placed outside each other and these angle members are arranged in parallel, and a wooden beam is interposed between both angles.

The integrated beam may be arranged in any of the building units irrespective of the position of the brace. For example, two brace reinforcements formed by crossing two braces in an X shape. It is preferably located between the two.

The metal reinforcing beam may be a single beam or a plurality of beams.

The plurality of wooden beams may be arranged irregularly, but it is preferable that a plurality of wooden beams are arranged at predetermined intervals.

[0013]

According to the present invention, a long building unit having sufficient structural strength can be obtained by a simple method of bridging a metal reinforcing beam between large girders without causing an extreme increase in member cost.

When the metal reinforcing beam is a rectangular steel pipe, the reinforcing beam is inexpensive because the rectangular steel pipe is a general-purpose member, and the rectangular steel pipe has a small cross-sectional area and a resistance to bending and twisting. Due to its large size, high strength reinforcement is achieved.

When the integrated beam is used, when the integrated beam is attached to the building unit, the metal reinforcing beam and the wooden beam are attached to the building unit at the same time. It will be simplified.

Here, when the integrated beam is a wooden beam fixed to the side surface of a rectangular steel pipe which is a metal reinforcing beam, or a horizontal piece of two angle members which is a metal reinforcing beam. If the wooden beams are interleaved between the two angles and the parts are arranged side by side to the outside, the shapes and dimensions of the wooden beams used for this integrated beam will be bridged within the building unit. Since it can be made the same as other wooden beams, the number of types of wooden beams does not increase, which facilitates management and handling. Furthermore, the metal reinforcing beam of the integrated beam and the wooden beam are fixed with an adhesive, but in the case of the integrated beam using the above two angles, fixing with an adhesive and fixing with a nail can be used together. it can. After the integrated beam is manufactured, the building unit can be immediately mounted without waiting for the adhesive to harden, so that the manufacturing period of the building unit can be shortened.

The integrated beam has two braces X.
When placed between two brace stiffeners that are crossed in a shape, an integral beam reinforces the space between these brace stiffeners, and the entire building unit is integrated with the two brace stiffeners. The beam has sufficient strength.

Further, when the wooden beam and the metal reinforcing beam are separately arranged, the metal reinforcing beam can be arranged at the most suitable position for reinforcing the building unit, The arrangement of the crossbeams can also be set to the most suitable position for fixing the nail of the planar internal structure material.

When a plurality of metal reinforcing beams are used, a long span beam having a long span can be reinforced at a plurality of places, so that a larger building unit can be obtained.

Further, when a plurality of wooden beam members are arranged at a predetermined interval, the planar internal working material may be fixed to the pitch of the wooden beam members, and this internal working material is surely attached to the building unit.
