Abstract

PROBLEM TO BE SOLVED: To constitute a house unit connected body which satisfies required structural properties by connecting a plurality of house units, each of which, however, does not satisfy requirements, which are required for a single house unit in a unit house. SOLUTION: Bolt holes are drilled in webs 1b, 2b of beams 1, 2 made of H-section steel disposed in a ceiling of house units A, B and in mount plates 3b, 3c of an H-shaped strength connection member 3, and high-strength bolts are inserted into these holes to connect the beams 1, 2 of the units A, B to each other. And floor beams of an upper story house unit and ceiling beams of a lower story house unit are connected directly one to the other by high- strength bolts. Each of the units A, B does not satisfy structural properties with respect to design loads specified in building standard; however, by connecting the units through the member 3, structural properties can be satisfied. Thus amounts and weights of steel frames of columns and beams can be reduced and living space can be expanded, while structural properties required by design load are satisfied.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit housing constructed by combining a plurality of housing units, and more particularly to a housing unit by combining housing units that do not satisfy the structural performance required by a design load. The present invention relates to a unit house configured to obtain a required strength.

[0002]

2. Description of the Related Art A typical example of a frame structure of a unit house constructed by combining a plurality of house units is shown in FIG. 4, for example. That is,
In FIG. 4, the columns 51, 52, 53, 54 of a plurality (four) of housing units are adjacent to each other back to back, and a plurality of columns are provided on the side surfaces of the columns 51, 52, 53, 54. Are protruded in the horizontal direction by welding.

Reference numeral 56 denotes a first-floor ceiling beam, which is inserted into the lower joint piece 55 and welded or bolted. Reference numeral 57 denotes a second floor floor beam which is inserted into the upper joint piece 55 and welded or bolted. Each housing unit composed of these pillars 51, 52, 53, 54, the first-floor ceiling beam 56 and the second-floor floor beam 57,
Each of them is configured to have a sufficient allowable strength and allowable distortion with respect to the design load.

[0004]

However, in the case of the conventional example illustrated in FIG. 4, a plurality of housing units individually satisfy the allowable strength and allowable distortion, and therefore, these housing units are combined. When the combined housing unit is used, the steel frames such as columns and beams are overlapped, the amount of steel frames is increased, the cost is increased, and the total weight of the building is unnecessarily increased. Further, in the conventional unit housing, there is a disadvantage that the floor plan is limited by the unit because the shape of the steel frame member becomes large.

As described above, in a conventional unit house,
Although each housing unit is structurally independent and is configured by combining each housing unit on the end, by combining each housing unit, let's satisfy the structural performance of the entire housing unit assembly. There was no configuration and no technical idea.

The unit housing according to the present invention is a completely new technology developed in view of many of these conventional problems, and in particular, a plurality of housings that do not satisfy the structural performance required by the design load. It is an object of the present invention to provide a completely new unit housing technique in which units can be connected to each other via a force-resistant connecting member to form a housing unit combined body, so that sufficient strength can be obtained.

[0007]

The unit housing according to the present invention is a completely new technology which fundamentally improves the above-mentioned conventional problems, and the gist of the invention is to combine a plurality of housing units. In a unit house to be constructed, a plurality of house units configured such that each house unit does not satisfy the structural performance required by a design load are connected to each other via a load-bearing connection member to connect the house units. A unit house comprising a body, wherein the combined house unit satisfies the structural performance required by a design load.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a unit house according to the present invention will be specifically described with reference to the drawings. FIG. 1 is a plan view of a main part of a frame structure of a unit house according to a first embodiment of the present invention. FIG. 2 is a perspective view showing a main part of the skeleton structure of FIG. 1, and FIG. 3 is a perspective explanatory view of a main part of the skeleton structure of the unit house according to the second embodiment of the present invention.

A unit house according to a first embodiment of the present invention will be described below with reference to FIGS. 1 and 2. That is, in the figure, A and B are housing units, respectively, and beams 1 and 2 made of H-shaped steel are respectively provided on the girder side of the ceiling.
Is arranged. These beams 1 and 2 have upper flanges 1a and 2a, webs 1b and 2b and lower flanges 1c and 2 respectively.
c.

Reference numeral 3 denotes an H-shaped load-bearing coupling member, which is formed in an H-shape by integrally attaching mounting plates 3b and 3c to both ends of a connection reinforcing member 3a, respectively. A plurality of bolt holes 4 are formed at predetermined positions of these mounting plates 3b and 3c. Bolt holes 5 are also formed at predetermined positions of the webs 1b and 2b of the beams 1 and 2.

The beams 1 of the housing unit A and the beams 2 of the housing unit B are connected to each other via a plurality of load-bearing connecting members 3, and this connection can form a housing unit combined body. Therefore, with such a configuration, it is possible to obtain the structural performance required by the design load such as the wind load, the seismic load, the self-weight, and the load specified by the Building Standard Law of each individual of the housing units A and B. It is configured to be able to. The structural performance required by such a design load includes, for example, proof stress, deflection, distortion, rigidity, interlayer deformation angle, and the like.

For example, each of the housing units A and B alone satisfies the structural performance of the ceiling beam with respect to any of the design loads such as the wind load, the seismic load, the own weight, and the loading load specified by the building standards. However, even when the structural performance of the housing unit is not satisfied, when the housing units A and B are connected by the load-bearing connecting member 3 to form a housing unit combined body as described above, the housing units A and B are not provided. Can compensate for the missing parts in each individual and strengthen them.

In the implementation of the unit housing of the first embodiment, when the housing unit A is produced in a factory, a plurality of load-bearing coupling members 3 are kept at predetermined intervals on the side surfaces of the web 1b of the beam 1 in advance. And high tension bolts 6 in bolt holes 4 and 5.
And a nut (not shown) is attached and fixed.

Next, the housing unit A to which the plurality of load bearing members 3 are fixed is installed on a construction site, and the housing unit B is placed next to the housing unit A at a predetermined interval. Subsequently, the mounting plate 3c of the load-bearing coupling member 3 is brought into contact with the web 2b of the beam 2 of the housing unit B, and is guided by a sino so that the bolt holes 4 and 5 formed in advance therewith match. By inserting the high tension bolt 6 into the bolt holes 4 and 5 and caulking with a nut, the two can be connected to each other.

If the beam 2 or the force-resistant connecting member 3 of the housing unit B is not manufactured with high accuracy, the bolt holes 4
In this case, it is difficult to make the bolts 5 coincide with each other at the construction site. In this case, the bolt holes 5 provided in the web 2b of the beam 2 are made to be stupid holes, thereby making it easier to work at the construction site. .

Since two or more of the above-mentioned load-bearing connection members 3 are attached to the beams 1 and 2, the whole is adjusted while checking the relative positions of the adjacent housing units A and B, and each of the load-bearing connection members 3 is connected. It is necessary to fix it little by little. In the above-described embodiment, the structure in which the girder beams of the ceiling beams of the housing units A and B are connected to each other is described. However, the connection of the wife beams of the housing units A and B and the connection of the base beams are connected. In this case as well, the connection can be made by the completely same configuration.

Referring to FIG. 3, a unit house according to a second embodiment of the present invention will be described below. That is, C is a lower-floor housing unit, and the main part of the frame is composed of columns 7 and ceiling beams 8, and these columns 7 and ceiling beams 8 are assembled in advance in a factory. .

Next, D is an upper-floor housing unit, the main part of which is composed of pillars 9 and floor beams 10,
A floor plate 11 made of an ALC plate is previously laid at a factory on a flange portion of the floor beam 10.

In assembling the unit house according to the second embodiment, the lower-floor house unit C and the upper-floor house unit D are transported to the building site, and the lower-floor house unit C is installed at a predetermined place. Lift the upper floor housing unit D,
After being placed on the lower-floor housing unit C, the floor beam 10 of the upper-floor housing unit D and the ceiling beam 8 of the lower-floor housing unit C are connected to a high-tensile bolt 12 and a nut 13 as a force-resistant connecting member.
It can be configured by connecting and fixing with.

In the case of the second embodiment, as in the case of the first embodiment, the structural performance of the floor beams and ceiling beams is not satisfied with the individual housing units C and D alone with respect to the design load. Although the structural performance required as a unit is not satisfied, the floor beams 10 and the ceiling beams 8 of the housing units C and D are connected by a high tension bolt 12 as a force-resistant connecting member to form a housing unit combined body. Thereby, it is possible to satisfy the structural performance required by the design load determined by the Building Standard Law and the like.

In the first and second embodiments, the housing units A, B, C,
Although the description has been given of the case where the housing unit combination is formed using D, the present invention can be applied as it is to a wooden house unit that does not use such a steel frame.
