Description

[Detailed explanation of the idea] Chain blocks and turnbuckles are used to correct the slope of steel buildings, but in order to correct the slope, wires are connected from the roof pillars to the grounded pillars on each side of the building. At least 8 are required, as one chain block or turnbuckle must be used for each wire. The use of a chain block has the disadvantage that the chain block itself is expensive and the operation is complicated, while the use of a turnbuckle has the disadvantage of poor efficiency since it must be done manually. The inventor has attempted to solve these drawbacks and provide an efficient vise for adjusting the slope of a building by using an impact wrench that has a simple structure and can tighten or loosen nuts.

Next, the structure will be explained in detail based on the drawings.

(A) Form a bullet-shaped towing ring 1 with a width that allows an impact wrench to fit in a round iron rod having an appropriate diameter, and bend the ends inward at right angles.
A reinforcing rod 2 is passed and welded to the part that corresponds to the neck of the cannonball, and a hole 5 is provided in the center of an iron plate 4 of an appropriate thickness through which a bolt with a nut 3 can be inserted. Place and fix by welding.

(B) Carve a male square screw 6 on the outer periphery of the bolt with nut 3.

(C) Drill a hole in the center of a circular iron plate with an appropriate thickness at one end of the iron tube 7 with an appropriate diameter and length, and insert a circular iron plate 8 with a female square screw carved into the inner wall of the hole. A circular iron plate 9 is fitted and welded to the other end, and a hole 10 is drilled through the iron cylinder 7 and the circular iron plate 9, and a fastening ring 1 is inserted through the hole 10.
1 is attached loosely, and the reinforcing rod 12 is passed to the tightening ring 11 and welded.

A bolt 3 with a nut having a male square screw 6 is inserted into a hole 5 in the center of an iron plate 4 and is screwed into a female square screw hole provided in the center of an iron plate 8 of an iron cylinder 7.

Next, one embodiment will be described in detail.

When the framework of the steel frame building is completed, loosen the bolts at the steel frame joints and run the wire ropes 16 diagonally from the roof corners to the ground corners inside the four surrounding sides of the steel frame building, and tighten the tie rings 11 of the steel frame legs on the ground. , tie the traction ring 1 to the wire rope 16 from the rooftop, hold the handle 14 of the impact wrench 13, and fit the hexagonal socket of the impact wrench into the hexagonal bolt of the bolt with nut 3 from the traction ring 1 side. By operating the switch 15 of the handle 14 and turning the bolt 3 with a nut, the traction ring 1 is pulled toward the iron tube 7 via the square screw. If the wire rope 16 is pulled appropriately, the rotation of the impact wrench 13 will be stopped, and the handle 14 will be removed from the traction ring 1, and the traction ring 1 attached to the next wire rope 16 will be tightened using the impact wrench 13 to tighten the bolt 3 with a nut. Turn the
The wire rope 16 is appropriately tensioned as described above. After this operation is carried out sequentially by pulling the diagonal wire rope 16 with a vise attached to the four sides around the steel building, a thread (hereinafter referred to as (referred to as Sagefuri) 1
7 and hang it down.If the wire is too short, add more wire to hang the weight down to the position of the steel leg on the ground.While checking the distance between the wire and the steel wall on the rooftop and below, check which side of the wire rope 16 is instructed to extend or shorten, and according to the instruction, holding an impact wrench 13, the bolt 3 with a nut attached to the wire rope 16 on the instructed side is rotated to guide the building to a vertical position.

After checking the distance between the Sagefuri 17 and the steel wall and confirming that the building has been corrected vertically, immediately tighten all the loosened bolts at the steel frame joint, remove the surrounding wire rope 16, and proceed with the slope correction work. finish.

As described above, the tie ring 11 is tied to the leg of the steel frame,
The traction ring 1 is tied to a diagonal wire rope 16, and the expansion and contraction of the wire rope 16 is carried out using the impact wrench 13 carried, so the work is very easy, and even if the impact wrench 13 is removed, the wire rope 16 remains at the corner Since it is fixed with screws and does not stretch, it is easy to adjust the slope of steel buildings, and has the advantage of being inexpensive to manufacture and reusable.
