Description

[Detailed description of the invention] (Industrial application field) The present invention relates in particular to reinforcement structures for housing units.

(Prior art) Generally speaking, as a housing unit,
The one described in the No. 2 publication, etc. is known.

This housing unit has pillars at the four corners,
A steel frame structure was constructed with ceiling beams and floor beams placed between the columns. When these housing units are stacked one above the other, the pillars of the upper housing unit overlap the pillars of the lower housing unit, and the lower housing unit supports the load of the upper housing unit with its four corner pillars. was.

In addition, when constructing a house by connecting multiple housing units, in addition to the basic unit of the basic size, an auxiliary unit whose width on the gable side or girder side is narrower than that of the basic unit is used. When stacking an auxiliary unit on top of the unit, two of the four corner pillars of the auxiliary unit are placed on the pillars of the basic unit below, and the other two are placed in the middle of the ceiling beams. It turns out. Therefore, conventionally, as shown in Fig. 8, in order to improve safety when a particularly large load is applied to the housing unit 2 on which the auxiliary unit l is stacked, the pillars of the auxiliary unit l are stacked on top of each other. A reinforcing structure was used in which a central pillar 4 was erected at a position corresponding to 3.

(Problem to be Solved by the Invention) However, in such conventional housing units, since a reinforcing structure such as a middle pillar is provided between the pillars, the middle part of the wall on the gable side of the housing unit It became impossible to provide openings such as doors and windows in some areas, and in most cases blind walls were to be provided. In this way, the problem arises that the use of auxiliary units conversely limits the planning width of the house.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and in order to achieve this purpose, in the present invention, pillars arranged at the four corners, In a housing unit in which a steel frame structure is constituted by ceiling beams and floor beams arranged between the columns, the steel frame structure includes a structure in which the ceiling beams on the gable side and the ceiling beams on the girder side are connected to each other. The method was to install steel reinforcement beams.

(Function) In the housing unit of the present invention, since the steel reinforcing beam is constructed by connecting the ceiling beam on the gable side and the ceiling beam on the girder side, the ceiling beam on the gable side or the ceiling beam on the girder side is When a load is applied from above to one of the beams, the reinforcement beam distributes the load to the other ceiling beam. Therefore, the load from above is
Strength is improved because it is supported by both the ceiling beam on the gable side and the ceiling beam on the girder side.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The figure shows two types of basic units A and B, each with four orders of magnitude different in width, arranged on a foundation E in two stages, and a reinforcing unit C having the same external dimensions as the basic units A and B. An auxiliary unit D, which is placed on the first floor next to unit A and whose width on the gable side is approximately half that of the basic units A and B, is placed on top of the reinforcement unit C. It is a unit housing.

In this example, these housing units A and B.

Figures 1 to 7 for reinforcement unit C among C and D.
This will be explained with reference to the figures.

First, in these housing units A, B, C, and D, as shown in FIG. Mainly composed of a ceiling beam 12 and a floor beam 13, a steel reinforcement beam 14 is constructed between the girder side floor beams 13b and 13b so as to be parallel to the girder side floor beam 13a. By floor beam 13
has been reinforced. Furthermore, in this steel structure IO, a ceiling joist 15 for attaching ceiling material is installed between the girder ceiling beams 12b and 12b, and a floor joist 16 for attaching flooring material is installed between the girder floor beams 13b and 13b. .

Reinforcement unit C differs from basic unit A in that a reinforcement structure for ceiling beams 12 is added to the above-mentioned steel structure, and as shown in FIG. Gable ceiling beams 12a are installed at three locations between the gable ceiling beams 12b and 12b, and girder reinforcement beams 18 are installed at three locations between the gable ceiling beams 12a and the gable reinforcement beams 17, respectively.

The girder reinforcing beam 17 is provided parallel to the girder ceiling beam 12a with a narrow interval therebetween, and the girder reinforcing beam 1
8 is formed short so as to correspond to the interval between the end ceiling beam 12a and the end reinforcement beam 17, and is provided parallel to the girder ceiling beam 12b. The girder reinforcing beam 18 located in the middle of the three girder reinforcing beams 18 is connected to the auxiliary unit D in the construction state.
It is connected to the gable ceiling beam 12a at the center position of the gable ceiling beam 12a, which overlaps with the pillar 11.

Furthermore, these reinforcing beams 17, 18 are formed of steel frames with a cross-sectional shape, and are attached to the ceiling beam 12 by screwing bolts 21, 22 and seats 23, 24 through mounting plates 19, 20. It is being done.

As shown in FIG. 4, the girder reinforcing beam 18 is attached to the upper part of the mounting plate 20 so that its upper surface coincides with the upper surface of the ceiling beam 12, and the end reinforcing beam 17 is, as shown in FIG. It is attached to the middle part of the mounting plate 19 so as to be placed below the girder reinforcing beam 18.

Next, a fastening structure between the reinforcing unit C and the auxiliary unit D will be explained.

As shown in FIG. 6, in the auxiliary unit D, the two columns 11.11 on the foundation unit A side are the columns 11.11 on the reinforcement unit C.
11, and the two outer columns 11.11 overlap the center portion of the gable ceiling beam 12a of the reinforcing unit C.

As shown in FIG. 6, the reinforcing unit C and the auxiliary unit D are fastened by a positioning joint bin 25 and a nut 26 in the portion where the columns 11 and 11 overlap, and the column 11 and the ceiling beam 12 are In the vicinity of the overlapped portion, the bolt 28 is inserted through the fastening plate 27.
．． It is fastened with a nut 29. Note that a pillar support plate 30 is interposed at the portion where the pillar 11 and the ceiling beam 12 overlap.

As shown in FIG. 7, the fastening plate 26 and the pillar support plate 29 are connected to the pillar 11 and the ceiling beam 12 through a joint piece 31 by spot welding or arc welding. This is to allow for the thickness of the inner piece 31 and to maintain the auxiliary unit D horizontally.

Therefore, the reinforcing unit C of the present invention includes the auxiliary unit D.
A load of
The load acting on the partial girder reinforcement beam I8 to the end reinforcement beam 17
and is distributed to the girder ceiling beam 12b. That is, the reinforcing unit C supports the auxiliary unit D with the pillar 11 and the gable ceiling beam 12a.
In addition to this, it is also supported by the girder ceiling beam 12b, which improves the strength.

Furthermore, since the girder reinforcing beam 18 is formed in a short shape, the girder ceiling beam 12a directly receives the load of the auxiliary unit D.
The reinforcing effect can be particularly enhanced.

As described above, since the reinforcing unit C of the present invention has a reinforcing structure in which the reinforcing beams 17 and 18 are installed between the ceiling beams 12,
Even if the auxiliary unit D is stacked on top, it is strong enough to withstand earthquakes and snowfall, and openings such as windows and doors can be arbitrarily provided on the sides of all units.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are design changes within the scope of the gist of the present invention, they are included in the present invention. It will be done.

For example, in the embodiment, the one-digit auxiliary beam was installed between the gable ceiling beam and the gutter auxiliary beam, but it may be intersected with the girder auxiliary beam and provided between the gable ceiling beams. Alternatively, it may be installed diagonally between the ceiling beam on the gable side and the ceiling beam on the girder.

In addition, when used with an auxiliary unit whose width is half that of the basic unit, install a girder reinforcement beam between the girder reinforcement beams and the girder reinforcement beam between this girder reinforcement beam and the girder ceiling beam. You can.

(Effects of the Invention) As explained above, since the housing unit of the present invention has a reinforced structure in which reinforcing beams are installed between ceiling beams, narrow auxiliary units can be stacked on top. Although it is strong enough to withstand earthquakes and snowfall, openings such as windows and doors can be arbitrarily provided on the sides of all units, and the breadth width can be expanded.
