Description

Description: TECHNICAL FIELD The present invention relates to a unit frame of a building. The present invention relates to a unit frame forming a frame of a housing unit in an industrialized house.

(Background technology)

In recent years, a construction method of transporting a plurality of types of housing units manufactured in a factory in advance to a building site, and combining them to build a building has been adopted.

Normally, a housing unit forms a rectangular parallelepiped unit frame by connecting the upper and lower ends of four pillars arranged at the four corners to each other with four beams, and forms an outer wall panel on the unit frame. , An inner wall panel, a ceiling panel, a floor panel, and the like.

2. Description of the Related Art Conventionally, when a unit frame of a housing unit is configured, a connecting portion between an adjacent column and a beam is integrally connected by welding or the like to form a rigid frame structure (rigid connection type). But,
In such a structure, since each connecting portion has to be welded, there are disadvantages in that the work is troublesome and time-consuming, and a diaphragm or the like must be built in the pillar.

Therefore, it is considered that the above-mentioned disadvantage can be solved by connecting the connecting portions between adjacent columns and beams with pins or the like, that is, by using a pin-joined unit frame as in a lightweight steel frame prefabricated house. However, in this case, since the rigidity and the resistance against external force are inferior to those of the rigid joint type unit frame having the rigid frame structure, it is necessary to insert a brace on a predetermined surface to secure the same degree of rigidity and resistance.

[Problems to be solved by the invention]

As described above, the pin-joined unit frame has an advantage that the work of connecting the column and the beam is relatively simple because the work of welding the connecting portion is unnecessary. However, since each surface is closed by the reinforcing brace, there is a disadvantage that it is difficult to secure an opening for providing a window or a door. As a result, the degree of freedom in design is limited.

Here, an object of the present invention is to provide a unit frame of a building in which the disadvantages are eliminated while maintaining the advantages of the unit frame in which the connecting portions between the adjacent columns and beams are joined by pins.

[Means for solving the problem]

Therefore, in the present invention, the adjacent column and the beam are pin-joined to form a rectangular parallelepiped skeleton of a predetermined module having a reference dimension of 1 module, and the upper and lower opposite beams of the skeleton and both ends of the upper and lower beams A portion connecting at least one of the pillars in at least one plane formed by the pillars connecting the sections and having a width dimension based on the reference dimension and a height dimension between the upper and lower beams. A panel-shaped load-bearing wall, which is formed to have a height dimension that fits into the panel and has peripheral walls on four sides, is attached in a state of being fitted between the upper and lower beams.

Here, as the load-bearing wall, a load-bearing wall made of lightweight cellular concrete with reinforcing steel bars whose width and height are formed to the predetermined dimensions, or in a frame formed with the width and height dimensions to the predetermined dimensions. A load-bearing wall or the like in which braces are arranged in an X shape can be used.

[Operation] Since a load-bearing wall is attached to at least one plane formed by beams corresponding to the upper and lower portions and columns connecting the both ends of the upper and lower beams, the rigidity of the unit frame is reduced by the load-bearing walls. Strength can be increased.

Moreover, the load-bearing wall is a panel having peripheral walls on four sides,
It is attached to at least one of the columns in the plane and is fitted in a state of being fitted between the upper and lower beams, that is, three of the four peripheral walls of the load-bearing wall form the column constituting the surface. Since it is attached in contact with the upper and lower beams, the deformation of the connecting portion (the connecting portion by pin bonding) between the column and the beam can be effectively suppressed. Therefore, the disadvantage associated with the use of the column and the beam with the pin connection, that is, the disadvantage that the rigidity and the proof stress are reduced can be effectively solved. Needless to say, since the connection between the column and the beam is a pin joint, the connection operation is also easy.

In addition, since the bearing wall has a width dimension based on the reference dimension and a height dimension formed so as to fit between the upper and lower beams, it is necessary to mount the bearing wall as it is on the surface on which it is mounted. Can be. In addition, even when secondary parts such as window frame sashes and doors are mounted on the surface on which the load-bearing walls are mounted, the remaining width in that surface is also based on the reference size. Is standardized based on the reference dimensions, it can be used as it is. For example, the width of one surface composed of beams opposed to the upper and lower sides of the skeleton and columns connecting the both ends of the upper and lower beams is 4 modules, and the width of the load-bearing wall is 1
In the case of a module, the remaining width obtained by subtracting the width of the load-bearing wall from the width in the plane is three modules, that is, based on the reference size, so that a secondary component standardized in advance can be used as it is. Therefore, since the openings such as windows and doors can be easily secured, there is little problem that the degree of freedom of design is limited.

〔Example〕

FIG. 1 shows a first embodiment. In the figure, reference numeral 1 denotes a unit frame which constitutes a frame of a housing unit manufactured in advance in the industry. The unit frame 1 is composed of four pillars 2A to 2D arranged at four corners and adjacent pillars 2A to 2D.
The ceiling beams 3A to 3D and the floor beams 4A to 4D interconnecting the upper end and the lower end of the 2A to 2D, respectively, are formed into a rectangular frame structure of a predetermined module having a standard size of one module. I have. The connecting portions between the columns 2A to 2D and the ceiling beams 3A to 3D and the floor beams 4A to 4D are connected by pin bonding. Specifically, ceiling beams 3A to 3D and floor beams 4A to 4D are attached to brackets provided on columns 2A to 2D via bolts (such as high-strength bolts) and pins (not shown) such as rivets.
Are connected.

In addition, on the surface formed by the ceiling beams 3A to 3D, that is, on the ceiling surface side, a small beam 5 is provided between the opposing long side ceiling beams 3A and 3B.
Are provided at predetermined intervals, and brace 6 is provided at diagonal positions. Further, on the surface formed by the floor beams 4A to 4D, that is, the floor surface side, small beams 7 are provided at predetermined intervals between the opposing long side ceiling beams 4A and 4B.

In addition, ceiling beams 3A to 3D and floor beams 4A to 4D facing up and down
And at a position adjacent to at least one of the four side surfaces formed by the columns 2A to 2D connecting the opposite ends of the opposing beams and at least one of the columns in the plane, At a position near the column 2B in the surface 8 formed by the ceiling beam 3B, the floor beam 4B, and the columns 2B, 2C, a bearing wall 11 is attached via a bolt or the like in contact with the column 2B.

The load-bearing wall 11 has a width dimension based on the reference dimension, specifically, a width dimension about 1/4 of the width in the surface 8 and a height dimension between the upper and lower beams 3B, 4B. It is formed in a plate-like shape by lightweight cellular concrete having a size having a height to be fitted and having a reinforcing steel bar inside the inner fold. That is, it is formed in a panel shape having peripheral walls at four corners.

Accordingly, in a factory, a unit frame 1 in which the load-bearing walls 11 are inserted in a predetermined plane is manufactured, and a housing unit is manufactured by attaching an outer wall panel, an inner wall panel, a ceiling panel, a floor panel, and the like to the unit frame 1. I do.

At this time, regarding the unit frame 1 for which it is necessary to secure the opening of the window frame sash and the door, in the factory, the load-bearing wall 11 is set at a position other than the position where these are attached.
Is attached to manufacture the unit frame 1. The window frame sash can be attached using the load-bearing wall 11.

The housing units thus manufactured are transported to a construction site, where they can be combined to easily build an industrialized house. At this time, on the construction site, only the external finishing work between the adjacent housing units is required, so that the on-site work can be reduced. That is, installation of an outer wall panel, an inner wall panel, a ceiling panel, a floor panel, and the like, and further, installation of a window frame sash and the like can be performed in advance by a factory, so that on-site work can be reduced and quality can be stabilized.

In addition, since the unit frame 1 has a structure in which the load-bearing walls 11 are attached in any plane, a large rigidity and strength can be imparted to the housing unit. Therefore, the rigidity and proof stress of the house can be increased. At the same time, it can also serve as an interior base material for the load-bearing wall 11. Of course, the connecting portions between the adjacent columns 2A to 2D and the beams 3A to 3D and 4A to 4D are also pin-joined, so that the connecting operation can be easily performed.

Second Embodiment FIG. 2 shows a second embodiment. In the description of FIG. 5, the same components as those in FIG. 1 described above are denoted by the same reference numerals, and description thereof will be omitted or simplified.

In the present embodiment, instead of the load-bearing walls 11 in the first embodiment, frames whose width is formed to a width based on the reference size and whose height is formed to a height to fit between the upper and lower beams. This is a case where a load-bearing wall 21 in which braces 23 are arranged in an X shape in a body 22 is used. That is, the frame 22 having the peripheral walls at the four corners
In this case, a panel-shaped load-bearing wall 21 in which braces 23 are arranged in an X shape is used.

Even when such a load bearing wall 21 is used, the same effect as in the first embodiment can be expected.

Note that, in each of the above embodiments, the ceiling beams 3A to
One of the four side surfaces formed by the 3D and floor beams 4A to 4D and the columns 2A to 2D connecting between both ends of the opposing beams.
Although the example in which the load bearing walls 11 and 21 are attached in one surface has been described, the bearing walls 11 and 21 may be attached to each of the four side surfaces.

In the above embodiment, one load-bearing wall 1 is provided in one plane.
Although the first and the first are mounted, two or more load-bearing walls 11 and 21 may be mounted in one plane.

For example, if the size of the building is different, such as a two-story, three-story, or four-story building, the required number of load-bearing walls 11 and 21 are required so that rigidity and strength can be obtained according to the size of the building. Is incorporated in a predetermined position of the unit frame 1, the unit frame 1 can be shared regardless of the size of the building. In other words, conventionally, it is necessary to change the cross-section of the columns and beams of the unit frame according to the size of the building, and to set a dedicated unit frame such as "for three floors". Thus, the unit frame 1 can be shared. In other words, the necessary rigidity and proof strength can be obtained only by incorporating the load-bearing walls 11 and 21, and thus there is an advantage that a structure corresponding to the scale of the building can be easily provided.
