Description

[Detailed Description of the Invention] The present invention relates to a novel place used for reinforcing lightweight steel buildings.

The present applicant has previously proposed a new method of reinforcing lightweight steel buildings using a fixed length of place without turnbuckles.

In this method, one end of the place is first fixed to one of a pair of place fixing pieces installed opposite to each other on the building side such as columns and beams, and then the other end and the other place fixing piece are pulled together using a separate pulling tool. The method is to pull it together and fix it.

The object of the present invention is to provide a new place for use in reinforcing steel buildings by this method.

Next, an embodiment of the place according to the present invention will be described based on the drawings.

In Fig. 1, 1 and 2 are the first
The plates 3 and 4 are fixed to the other end of the steel bar and the second steel bar, and a male threaded portion 5°6 is provided at one end.

Reference numeral 7 denotes an elastic device having a configuration in which a band-shaped leaf spring 8 is bent into a U-shape and its both ends are connected by a connecting piece 9, as shown in detail in FIG. Both steel bars 1, 2 are formed by forming a hole in the center in the longitudinal direction, inserting the male threaded portions 5.6 of the first and second steel bars 1, 2 into the base holes, and screwing in the nuts 10.11. are connected.

In addition, the plates 3, 4 and the place fixing pieces 13, 13, 21°2 fixed to the plates with bolts and nuts
In addition to the bolt insertion holes 3a, 4a, 13a, and 21a, the hole 1 has insertion holes 3b and 4 through which the arm of a pulling tool, which will be described later, is inserted.
b, 13b, and 21b are formed.

However, it is sufficient that the insertion hole through which the arm rod is inserted is formed at least only in the plate 4 and the place fixing piece 21 on the side to which the pulling tool is applied.

Further, 2a is a flat plate portion of the second steel bar 2, which is located at the intersection when the places are stretched in a crosswise manner.

Further, the shape of the leaf spring 8 is not limited to the U-shape, but may be formed in a non-linear shape from the connecting portion of the first steel bar 1 to both ends of the connecting piece 9.

To explain the procedure for installing the place with the above structure between the place fixing pieces on the building side, first, as shown in FIG. , is fixed with a nut, and then an arm rod 16 having a right-hand thread 15 and an arm rod 18 having a left-hand thread 17 are screwed into each end of the hexagonal nut 14. Prepare the tool 19, insert the tip of one arm rod 16 of the tool 19 into the insertion hole 4b of the plate 4, and insert the tip of the other arm rod 18 into one hole of the place fixing piece 21 provided at the upper end of the column 20. 21b, and tighten the hexagonal nut 14
Rotate with a wrench or other operating tool.

Then, since each of the arm rods 16 and 18 has a right-handed thread and a left-handed thread in opposite directions, the rotation of the hexagonal nut 14 causes the arm rods 16 and 18 to move toward each other.

Therefore, the plate 4 through which the arm rods 16 and 18 are inserted and the place fixing piece 21 are drawn together as the arm rods 16 and 18 move.

Then, with the bolt insertion hole 4a of the plate 4 and the bolt insertion hole 21a of the place fixing piece 21 aligned, the rotation of the hexagonal nut 14 is stopped, and the bolt is inserted into both insertion holes 4a and 21a, and tightened with the nut. Fix it by doing this.

When the fixing is completed, the pulling tool 19 is removed, and a new place is then stretched between the place fixing piece 13 at the lower end of the column 20 and the place fixing piece 21 at the upper end of the column 12 in the same manner as above.

In this case, the length of each place and the interval between the place fixing pieces are slightly different due to errors in manufacturing, processing, and construction accuracy as described above, but since each place is interposed by the ammunition 7, At the time of place tensioning, the bullet 7 is elastically deformed according to the tensile force, and tensioning can be performed even if there is the accuracy error.

Since the place according to the present invention is constructed as described above, in other words, to summarize, two steel bars are connected via an elastic bullet, so that when the place is stretched, the precision of manufacturing, processing, and construction is achieved using the bullet. The above error can be effectively absorbed and tensioning can be done reliably and easily.

Therefore, the production of places is as much as is absorbed by the ammunition,
It also has the advantage that machining accuracy can be relaxed, and manufacturing and machining costs can be reduced accordingly.
