Description

[Detailed Description of the Invention] The present invention relates to a spanner used for constructing hooks for attaching sleds 1~, 1~tan, etc. to buildings, etc.

As is well known, this type of hook consists of a hook bolt, a nut, a gasket, and a washer.
The hook part of the hook bolt is inserted into a hole made in galvanized iron or the like, and the hook part of the hook bolt is engaged with the framework of the building, such as C-shaped steel, and the nut is tightened to the hook bolt to complete the construction. Hook pole 1 slightly protruding from
The hook part of the Hook Pol I, whose visibility is blocked by slate, galvanized iron, etc., must be engaged with the frame made of C-shaped steel, etc., by holding the tip of the hook.This engagement work is difficult, and we have taken great pains to secure it. However, if you do not tighten the nut with the hook bolt pulled toward you, the engagement will easily come off, and tightening the nut with this tension requires both hands, which can be dangerous when working at heights. To eliminate it, it would take one or two workers to work on the front and back sides of the slate or galvanized iron, etc.

Therefore, the present invention makes it easy to engage the hook bolt with the frame of the building, such as C-shaped steel, and in this engaged state, the hook can be easily tightened with one hand, reducing the risk of working at heights. The purpose of the attachment is to provide a wrench for hook construction, which can be installed using short hook bolts.

Next, an illustrated embodiment of the present invention will be described. The spanner of this embodiment includes a cylindrical spanner main body 1 and a shaft 2, and has a hexagonal bow-shaped spanner opening 3 at the front end of the spanner main body 1 that fits into the nut 12 of the hook 11. A shaft 2 is rotatably and longitudinally movably inserted into the spanner main body 1, and a hole 4 of a required depth is provided at the front end of the shaft 2 to be screwed into the hook bolt 13 of the hook 11. A handle portion 5 having a larger diameter than the shaft 2 is formed at the rear of the shaft 2, and a flange-like stepped portion 7 for preventing the wrench main body 1 from slipping forward is formed at the front portion of the shaft 2, and a handle portion 5 that engages with the flange-like stepped portion 7 is formed at the front portion of the shaft 2. A mating inner flange-like stepped portion 6 is formed at the rear of the spanner main body 1, and finely uneven non-slip surfaces 8, 9 are provided on the outer periphery of the spanner main body 1 and the outer periphery of the handle portion 5, respectively.
The front end of the handle portion 5 serves as a stepped portion 10 for preventing the spanner main body 1 from slipping out from behind.

The hook 11 has a felt packing 15 and a washer 16 at the tip of a hook bolt 13 having a hook portion 14 on the head.
Screws 1 to 12 are inserted in order through the holes.

Also, in the figure, 17 is the C-shaped steel that formed the frame of the building.
18 is a slate attached to the C-shaped steel 17.

When constructing the hook 11 using the spanner of this embodiment, the spanner main body 1 is moved back a little so that the front end of the shaft 2 is exposed slightly forward of the front end of the spanner main body 1 for easy viewing.
The screw hole 4 at the front end of the shaft is screwed into the hook bolt 13 to establish a connection state, and then the hook bolt 1 is inserted from the tip of the hook portion 14.
3 into the through hole 19 of the sleigh I.18, rotate it while grasping the handle part 5 to engage the foot part 14 of the hook bolt with the C-shaped steel 17, and then tighten the handle to prevent this attachment from coming off. While the part 5 is pulled backward, as shown in Fig. 1, move the spanner main body 1 forward with the thumb and index finger of the pulled hand 20, and fit the spanner mouth 3 into the nut I/12 of the hook. together,
Continue to rotate the spanner body 1 to tighten the nut 12,
At the end of this tightening, grasp the spanner main body 1 again, tighten the nut 12 even more strongly, then move the spanner main body 1 back to remove the nut 12, and at the same time, twist the shaft 2 back with the handle part 5 to remove it from the hook bolt 13. , the construction of the hook 11 is completed.

Furthermore, even if the wrench main body 1 is carried around by the handle 5 during this construction, the front escape of the spanner main body 1 is prevented by the engagement of the stepped portions 6 and 7.

As mentioned above, the spanner of the present invention has a shaft rotatably and longitudinally movably inserted into a cylindrical spanner main body which has a spanner opening at the front end that fits into a nut of a hook, and a hook at the front end of the shaft. It features a threaded hole for threading the hook bolt, a handle at the rear of the shaft, and stepped sections at the rear of the wrench and at the front of the shaft to prevent the front of the wrench from slipping out. When installing the hook, the hook pole 1 of the hook can be connected to the shaft, so the hook bolt can be easily engaged with the building frame such as C-shaped steel, and this connection can be maintained by tensioning the shaft using a wrench. The nut of the hook can be easily tightened with one hand, which prevents the danger of working at heights and improves the work efficiency of hook installation.The above effect is especially noticeable when installing hooks with short hook bolts. .
