BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation jig for building units. For example, the present invention relates to a transportation jig used to secure structural strength of an entrance building unit that constitutes an entrance portion of a unit building against vibration and impact during transportation or installation.

[0002]

BACKGROUND ART In building a building, a unit construction method is adopted in which a building unit is manufactured in a factory, which is transported to a construction site by a truck or the like, and then these are combined to build a building. As one of building units used in the unit construction method, the upper and lower ends of four columns are connected by upper and lower beams to form a rectangular parallelepiped frame frame, and an entrance porch is provided in the frame. A building unit for the entrance is known, which is configured with a entrance sash.

Conventionally, in an entrance building unit, when it is attempted to construct an entrance pouch in a frame frame formed in a rectangular parallelepiped shape by four pillars and an upper beam and a lower beam connecting these end portions, Part of the beam is removed to lower the top level of the entrance porch below the floor level of a normal building unit. However, in the frame frame having such a structure, that is, in the frame frame in which the beam is not connected between the one side ends of at least two adjacent columns, the frame, the outer wall, the inner wall, the ceiling material, etc. Not only is it difficult to install the unit, but when it is transported from a factory to a construction site by a truck or the like and installed, an unreasonable force is applied to the unit during transportation and installation, and there is a problem in that structural stability is lacking in stability.

Therefore, as a method for solving such a problem, a method disclosed in Japanese Utility Model Publication No. 63-49442 has been proposed. This is to connect the upper parts of the pillars at the four corners with four beams, connect the lower part of the beams forming at least two facing ridges to the pillars, and connect the opposite pillars at the ridges where the beams are not connected. This is a structure in which connecting pieces are welded at right angles to the facing surfaces, and a temporary beam member is detachably attached between the connecting pieces.

[0005]

However, in the above-mentioned conventional structure, since the connecting pieces must be welded at right angles to the facing surfaces of the columns facing each other at the ridge portions where the beams are not connected, that is, the length is long. Since the connecting piece has to be welded directly to the column, the processing is troublesome. Moreover, even if the unit is transported to the site and the temporary beam member is removed after installation, since the connecting piece remains on the facing surface of the pillar, the connecting piece may be an obstacle in the subsequent indoor configuration.

The object of the present invention is to solve the above-mentioned drawbacks of the prior art, to facilitate the manufacture, and to easily attach it in a factory and to remove it easily as needed. To provide a transportation jig.

[0007]

Therefore, a transportation jig for a building unit according to the present invention includes a plurality of columns and a plurality of beams connecting end portions of these columns, and at least two adjacent columns. Is a building unit transportation jig to be attached to a building unit having a structure in which a beam is not connected between the end portions on one side, and a pair is detachably attached to one end surface of at least two adjacent columns. And a temporary beam member having a connecting portion that is inserted between the pair of box-shaped members and has a connecting portion that is detachably connected to the box-shaped members at both ends.

[0008]

In the factory, box-shaped members are attached to the end faces on one side of at least two adjacent columns to which no beams are connected. Then, after inserting the temporary beam member between the pair of box-shaped members, the connecting portions at both ends thereof are attached to each box-shaped member. In this state, transport it to the construction site by truck, etc., then lift it with a crane and install it. After that, the temporary beam member is removed from between the pair of box-shaped members, and further, the pair of box-shaped members is removed from the column, if necessary.
