Description

Description: TECHNICAL FIELD The present invention relates to a housing unit, and sometimes to a temporary reinforcing structure for a housing unit having a steel box structure.

[Conventional technology]

This type of steel box structure housing unit, which is used to reduce the on-site man-hours, construction period, etc. in housing construction, basically consists of four beams that connect the ridge to the upper part of the four corner pillars. , The four floor beams forming the lower ridge are connected. A plurality of these box-shaped housing units are connected together to form the required housing. At this time, for example, the housing units for the entrance, pillow, downfloor, etc. used on the first floor are (The part that connects the lower ends of the columns)
It is necessary to use some of the floor beams without floor beams. FIG. 4 shows a perspective view of an example of a typical residential unit of this type used for the entrance.

In the figure, 20 is four pillars, 21 is four beams forming the upper ridge, 1 is a floor beam, 2 is a floor beam, but for the entrance,
There are no floor beams in parts 1a and 1b corresponding to the floor beams indicated by the one-dot chain line.

When manufacturing a housing unit of this kind of special structure at the factory, or when transporting the product from the factory to the construction site, if part of the floor beam is omitted, the strength and rigidity of the box-shaped structure, etc. It lacks stability and causes handling problems.
BACKGROUND ART Temporary reinforcing members (temporary beam members, etc.) are temporarily removably and temporarily fixed to a portion of a floor beam equivalent portion where a floor beam does not exist.

FIG. 5 is a bottom plan view showing an example of a conventional temporary reinforcement structure corresponding to the case of FIG.

In the figure, 1a is a temporary beam and 2a is a temporary beam. The joint portion 1c between the front end of the floor beam 1 and the end portion of the temporary beam 1a is butt bolted or temporarily welded, and the joint portion 2b at both ends of the temporary beam 2a to the temporary beam 1a is temporarily welded. The other end of the beam 1a is fixed to each column by bolts or temporary welding to 20 to temporarily complete the entire box-shaped structure to prevent deformation, and to prevent the manufacturing process, transportation, etc. I was dealing with the handling.

In addition, for example, in a housing unit for forming a downfloor, as a structure for temporary reinforcement of a case where the floor beam does not exist on one side of the floor beam equivalent portion, for example, Japanese Utility Model Laid-Open No. 63-49442 is disclosed, As shown in FIG. 4, there is no effective provisional reinforcement configuration example for the case where the floor beam does not exist on at least two sides of the floor beam equivalent portion.

[Problems to be solved by the invention]

However, in the conventional temporary reinforcement structure example as described above, the temporary beams 1a and the temporary beam 2a are temporarily welded to be assembled / attached, so that dimensional accuracy and productivity at the time of factory production are also improved. Also generally not good. That is, the spacing width dimension of the temporary beams 1a on both sides can be regulated relatively accurately only with the temporary beam 2a, but since there is no brace-like diagonal member, a certain degree of parallelogram deformation due to welding (see FIG. 5). It is inevitable).

Furthermore, since these are temporary welding structures, it was troublesome to remove the temporary reinforcing material when the installation of the housing unit was completed at the construction site, and it was necessary to repair the welding marks and the like.

The present invention has been made in view of the problems of the conventional temporary reinforcing method of the above type, and can be easily attached and detached to ensure accurate dimensions, and without requiring repair or the like after detachment. Another object of the present invention is to provide a temporary reinforcing structure for this type of housing unit that can be repeatedly used for housing units of the same shape.

[Means for solving the problem]

Therefore, in the present invention, a housing unit having a substantially rectangular parallelepiped outer shape and columns at four corners is used, and the lower ridge portion of the rectangular parallelepiped is regarded as a floor beam equivalent portion, and a pair of parallel floor beams are provided. There is a pair of floor beams in the predetermined length part of the corresponding part, there is no floor beam in the remaining length part, and a floor beam is installed between the pair of floor beams. In the housing unit, the reinforcing structure of the portion where the floor beam is not present is erected in the portion where the floor beam is not present, and is erected between the pair of temporary beams where both ends are bolted together and the pair of temporary beams. And a pair of length-adjusting formulas for connecting both ends of the temporary beam with bolts, and connecting both ends of the temporary beam and the floor beam with crossing in an X shape to each other. An attempt is made to achieve the above-mentioned object by comprising a brace member and Things.

[Action]

With the above-mentioned temporary reinforcement structure, each member can be easily attached / removed by bolt connection, no repair is required after the removal, and the adjustable brace member can ensure accurate dimensions. Further, each member can be removed after use and can be repeatedly used in a housing unit of the same shape.

〔Example〕

Hereinafter, the present invention will be described based on examples. FIG. 1 is a plan view of an essential part of a floor beam in a state where an embodiment of a temporary reinforcing structure according to the present invention is attached to a lower portion of a first-floor entrance housing unit,
