Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting plate and a connecting method of building units for positioning and connecting building units constituting a unit building.

[0002]

2. Description of the Related Art In building a unit-type building, a plurality of building units manufactured in advance in a factory are transported to a construction site, and the plurality of building units are connected in the construction site work. For example, before connecting a lower-floor building unit and an upper-floor building unit arranged vertically and horizontally, a hole is previously formed in the upper surface of the capital of the lower-floor building unit at the factory, and a nut is welded to the lower surface. Keep it fixed. Also, a hole is formed in the lower surface of the column base of the upper floor building unit. At a construction site, a lower-floor building unit is arranged adjacently in the horizontal direction, and a plurality of positioning pins having different heights are erected on the upper surface of the capitals of the lower-floor building unit. At this time, the positioning pin is erected on a nut welded to the column head. Subsequently, the hole formed in the connecting plate is inserted into the positioning pin, and the connecting plate is bridged between two adjacent lower-floor building units.

[0003] Next, the upper-floor building unit is hoisted above the lower-floor building unit by a crane, and a hole formed in the column base of the upper-floor building unit is inserted into a portion of the positioning pin projecting upward from the connecting plate. The upper floor building unit is stacked on the lower floor building unit. Finally, the upper-floor building unit and the lower-floor building unit are connected by inserting a connecting tool such as a bolt into a hole formed in the connecting plate, the column cap of the lower-floor building unit, and the column base of the upper-floor building unit. I do.

Further, as another example, a plurality of lower-floor building units are arranged adjacent to each other in the horizontal direction, and the lower-floor building units are assembled at the upper end of each pillar where these lower-floor building units are assembled. A structure has also been proposed in which a plurality of building units arranged adjacent to each other in the horizontal direction are connected via a flange portion and a fixing plate protruding in a gap formed (Japanese Patent Publication No. 60-44462). Specifically, a flange having a hole is welded to the side wall of the upper end of the pillar, and a plurality of positioning pins having different heights protruding from the fixing plate are provided. Thereafter, in a state where the lower-floor building units are collectively arranged, a plurality of lower-floor building units arranged horizontally adjacent to each other are interconnected by fitting positioning pins into holes of the respective flange portions. .

[0005]

However, in the former structure, the positioning pins are screwed into the nuts at the construction site and the positioning pins are manually attached to the plurality of columns of the building unit. There is a problem in that it takes time to mount the device, and it is difficult to improve the work efficiency in the field work. In addition, since the nut must be manually welded and fixed to the lower surfaces of the column heads of the plurality of columns, not only is it difficult to weld the nut, but the heat of this welding deforms the nut and the like, so the positioning pin to be attached is attached. There is a problem in that the accuracy of the vertical and horizontal positions is reduced.

[0006] On the other hand, in the latter structure (Japanese Patent Publication No. 60-44462), the problem associated with the former welding, specifically, a flange having a hole is manually welded and fixed to the upper end side wall of the column. In addition, the flange welding is not only difficult, but also the column and the like are deformed by the heat of this welding, so that the accuracy of the positioning pins fitted in the holes in the vertical and horizontal directions is reduced. is there. In addition, when the upper-floor building unit is arranged on the upper surface of the lower-floor building unit only by connecting the plurality of lower-floor building units arranged adjacently in the horizontal direction, a positioning pin for positioning the upper-floor building unit is provided. Since there is no connecting tool for connecting the upper and lower floor building units, it is necessary to newly provide a positioning pin or the like, and there is a problem that the operation becomes troublesome.

An object of the present invention is to provide a connecting plate and a connecting method of a building unit which can improve the accuracy of the position of a positioning pin and improve the work efficiency of field work.
