Description

[Detailed Description of the Invention] This invention relates to an attached building attachment device.

In recent prefabricated houses, various auxiliary buildings can be attached to the outer wall of the building body according to various uses. FIG. 1 shows an exploded perspective view of such an attached building, and its attachment to the foundation is carried out as follows. That is,
A fabric foundation 2 for supporting an attached building is formed on the outdoor side of a fabric foundation 1 that supports the building body, anchor bolts 3 are planted on the top surface of the fabric foundation 2, and an attached building 4 is placed on the fabric foundation 2. Place the anchor bolt 3 through the bolt insertion hole 5 formed on the bottom surface of the attached building 4,
A nut (not shown) is fastened to the anchor bolt 3 from inside the attached building 4 to connect the attached building 4 to the cloth foundation 2.

However, because the installation accuracy of the anchor bolt 3 to the cloth foundation 2 is difficult to achieve, the anchor bolt 3 shifts from the predetermined position and cannot be smoothly inserted into the bolt insertion hole 5. As a result, the cloth foundation of the attached building 4 2
This poses a problem in that it is difficult to attach the anchor bolt 3 to the anchor bolt 3, and the attachment position of the auxiliary building 4 also shifts in accordance with the shift of the anchor bolt 3.

It is therefore an object of this invention to provide an accessory building attachment device that allows accessory buildings to be easily and accurately attached to a foundation.

An embodiment of this invention will be described with reference to FIGS. 2 to 4. That is, this attached building attachment device uses the connecting fittings 6 shown in FIG. 2 to attach the attached building 4.
Connect to the cloth foundation 2. The connecting fitting 6 is a lower piece 6a.
It is a substantially U-shaped piece that is set longer than the upper piece 6b, and the upper piece 6b has a bolt insertion hole 6c, and the lower piece 6a has a bolt insertion hole 6c extending from a position corresponding to the bolt insertion hole 6c toward the tip of the lower piece 6a. Then, a bolt insertion slit 6d which is open at the tip thereof is formed. The installation procedure is
As shown in Figure 3, anchor bolts 3 are attached to the foundation 2.
After planting, the upper piece 6b of the connecting fitting 6 is placed along the lower surface of the attached building 4, and the bolts 7 are sequentially inserted into the bolt insertion hole 6c of the upper piece 6b and the bolt insertion hole 5 of the attached building 4, and the attached building is attached. The connecting fitting 6 is temporarily connected to the attached building 4 by temporarily tightening the nut 8 from the inside of the bolt 4, and the anchor bolt 3 is inserted into the bolt insertion slit 6d while adjusting the rotation of the connecting fitting 6 around the bolt 7. After placing the lower piece 6a on the cloth foundation 2 and positioning the attached building 4 in a predetermined position,
Tighten nut 9 to anchor bolt 3 and remove lower piece 6
A is fixed to the cloth foundation 2, and the nuts 8 are fully tightened to permanently fix the upper piece 6b and the attached building 4.

In this way, the upper piece 6b of the connecting fitting 6 is attached to the bolt 7.
It can be connected and fixed to the lower surface of the attached building 4 at any position rotated around the fulcrum, and the lower piece 6a
Since the anchor bolt 3 can be connected and fixed at any position along the bolt insertion slit 6d, even if the installation position of the anchor bolt 3 on the cloth foundation 2 is slightly shifted in the front, rear, left and right directions in the horizontal plane, the direction shift will not occur. can be corrected by rotating the connecting fitting 6 around the bolt 7, and the distance deviation can be corrected by rotating the connecting fitting 6 with the bolt 7 as a fulcrum.
This can be absorbed by adjusting the insertion position of the anchor bolt 3 into the hole d, and thus the attached building 4 can be installed in a predetermined position with high accuracy. In addition, when inserting the anchor bolts 3 into the bolt insertion slits 6d, after adjusting the direction of each connecting fitting 6 temporarily connected to the attached building 4 by rotating the bolt 7 as a fulcrum, each lower piece 6a is inserted into the cloth foundation 2. By sliding along the upper surface, each anchor bolt 3 can be smoothly inserted into the inside of the bolt insertion slit 6d from the opening at the end thereof, so that the work of fastening the connecting fitting 6 to the cloth foundation 2 can be performed quickly and easily. Ru.

As described above, the attached building attachment device of this invention includes a foundation, an anchor bolt planted on the upper surface of the foundation, an attached building placed on the foundation, a bolt insertion hole in the upper part, and a lower part. A substantially U-shaped connection in which bolt insertion slits extending from the base end to the distal end are formed in the upper piece, and the upper piece is bolted to the lower surface of the attached building, and the anchor bolt is inserted and fixed through the bolt insertion slit in the lower piece. Since it is equipped with metal fittings, it has the effect of allowing attached buildings to be easily and accurately attached to the foundation.
