Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretching member in a unit type building constructed by combining a plurality of building units, and can be used, for example, when installing equipment piping, wiring, etc. in a unit type building.

[0002]

[Background Art] A unit-type building such as a house is built by combining a plurality of building units produced at a factory at a construction site. This building unit has four pillars that are erected in four corners, It is provided with a framework composed of four ceiling beams and floor beams that connect the upper ends and the lower ends of these columns to each other, and are formed by attaching an inner wall, an outer wall, a ceiling surface material, a floor surface material, etc. to this frame. ing. In such a unit-type building, adjacent beams are joined by interposing box-shaped metal parts in the gaps between adjacent beams of horizontally adjacent building units, thereby increasing the strength of each beam and bending moment. There is known a technique for preventing twisting (lateral buckling) of each beam due to (Japanese Patent Publication No. 3-144036).

[0003]

By the way, a horizontal through hole is formed in a beam of a building unit, and, for example, a cylindrical guide member is attached to the through hole. It is carried out to pass the stretching member. In this case, since the guide member and the box-shaped metal member are separate members, there is a problem that the number of parts increases.

An object of the present invention is to provide a guide member for a stretchable member in a unit-type building, which can reduce the number of parts by sharing the parts.

[0005]

The guide member of the extending member in the unit type building according to the present invention has a through hole for inserting the extending member therein, and among the plurality of building units constituting the unit type building, It is characterized in that building units that are adjacent to each other in the horizontal direction are joined together.

In the guide member of the extension member in this unit type building, the guide member is divided into two parts, first and second.
Which have horizontal through-holes for extending members, are inserted into the openings formed in adjacent beams of adjacent building units, and are connected to each other. It may be combined. In this case, a spacer may be provided between the coupling members to keep the distance between the adjacent beams constant,
Further, each coupling member may be coupled by screwing a male screw formed on either one of these coupling members and a female screw formed on the other side.

In the present invention, the first and second connecting members are
The engaging portion formed on either one of these coupling members and the engaging portion formed on the other side are compressed and inserted into the through holes inside the one coupling member, and the compression is performed when engaging with the engaging portion. It may have a protrusion that is released and is locked to this engaging portion.

[0008]

According to the present invention as described above, since horizontally adjacent building units are joined by the guide member and the extending member is inserted into the through hole inside the guide member, one member laterally buckles. Can be used also as a guide for the stretching member, and thus the number of parts can be reduced.

Further, in the present invention, the guide member is composed of the first and second connecting members, and these connecting members are inserted into the openings formed in the adjacent beams of the building unit,
In addition, when the male screw and the female screw are coupled by screwing, the mutual coupling members may be inserted into the openings of the beams, and the male screw and the female screw may be screwed together. It becomes easy to connect the members.

In the present invention, when the engaging portion formed on one of the first and second connecting members is engaged with the protrusion formed on the other connecting member, the engaging portion is locked. ,
The first and second coupling members can be coupled with one touch.

Further, since the spacer 18 for keeping the interval between the adjacent ceiling beams 3 and 3 constant is provided between the first and second coupling members 11 and 12, the first and second coupling members 11 and 12,
When coupling 12 together, each coupling member 11, 12 may be screwed until the ceiling beams 3, 3 come into contact with the spacer 18, and the coupling adjustment is easy. In addition, since the groove 17 is formed in the flange portion 12B of the second coupling member 12, when the coupling members 11 and 12 are coupled to each other, a fastener such as a screwdriver is engaged with the groove 17 and tightened. Since it suffices, the connecting work can be performed easily. Furthermore, since the chamfers 14 are formed at the ends of the through holes 11C and 12C of the first and second coupling members 11 and 12, when the extending member 20 is passed through the through holes 11C and 12C, the extending member 20 Is less likely to be damaged, whereby the stretching member 20 is protected.

FIG. 3 shows a second embodiment of the present invention. In the above-mentioned embodiment, the guide member 10 is divided into the first connecting member 11 and the second connecting member 12, and the female screw 13 and the male screw 15 formed on these connecting members 11 and 12 are screwed together. Although the two members 11 and 12 are joined together by this method, in this embodiment, the guide member 10 'is composed of a bolt 31 and a nut 32, and these 31 and 32 are screwed together. That is, the nut 32 as the first coupling member is previously attached to the back side of the opening 6 in the one beam 3 by welding, and when the adjacent beams 3 and 3 are joined, the second
The bolt 31 as a connecting member of the
Thus, the spacer 18 is inserted so as to cover the outer periphery of the bolt 32, and is screwed into the nut 31. In addition, a through hole 32 </ b> A through which the extending member 20 is passed is opened inside the bolt 32. Even in such an embodiment, the above-described effect can be obtained, and in addition, a commercially available bolt and nut can be purchased and used as the guide member 10 'if the through hole 32A is open in the bolt. This has the effect of facilitating production.
