Description

[Detailed description of the invention] A. Purpose of the invention a. Industrial application field This invention relates to a corrugated frame that is attached to scaffolding for construction work.

b. Prior art and its problems Conventionally, the following drawbacks have been associated with corbel frames attached to scaffolding for construction work.

B. Requires special tools and time to install and remove.

(b) The narrow expansion/contraction width will get in the way during construction.

B. Structure of the invention a Means for solving the problem The present application attempts to solve the above-mentioned problem with the following structure. That is, the thing of the present application is a supporting frame consisting of a hollow horizontal member 2 and an insert member 3, and the hollow horizontal member 2 is a pipe body 2A of a predetermined size.
The left end 2B is open,
A right end wall 2D is stretched over the right end 2C, and a left hook 2E and a right hook 2F having an inverted U-shaped side surface are fixed at a predetermined interval to the back side of the pipe body 2A. 2E and right hook 2F,
When the hook is locked to a horizontal member 4A1 such as a frame scaffolding, pin holes H having a longitudinal direction are opened at positions located below the horizontal member 4A1 so as to correspond to each other, In addition, a pin 2I is inserted into and removed from the pin hole H, and a fixing screw 2K is provided near the tip of the pipe body 2A so as to be movable toward the inside of the pipe body 2A. 3 is composed of a pipe body 3A,
Further, an upwardly protruding piece 3B is fixed to the left end of the pipe body 3A, and is inserted into the hollow horizontal member 2 so as to be movable forward and backward.

b. Embodiment of the invention 1 is a corbel frame of the present invention, which is attached to a horizontal member 4A1 in a building frame 4A such as a known framework scaffolding 4.

2 is a hollow horizontal member, and has a pipe body 2A of predetermined dimensions.
The left end 2B is open,
A right end wall 2D is stretched over the right end 2C.

Therefore, a left hook 2E and a right hook 2F, each having an inverted U-shaped side surface, are fixed to the back side of the pipe body 2A at a predetermined distance.

These left hook 2E and right hook 2F are front parts 2E1, 2F1 and upper curved part 2E, respectively.
2, 2F2, and rear parts 2E3 and 2F3, and between the front part 2E1 and the rear part 2E3, and between the front part 2F1 and the rear part 2F3, when the hook is locked to the horizontal member 4A1, With the locations located below this horizontal member 4A1, pin holes H with the front and rear directions are arranged so as to correspond to each other.
has been established.

A pin 2I is inserted into this pin hole H in the front-rear direction, and a locking pawl 2I1 is provided at one end with a known structure so that it can be raised and lowered freely, and a chain 2I2 for preventing loss is provided at the other end. installed.

2J is a prismatic body whose right end is fixed to the right end wall 2D, and is located at the axis of the pipe body 2A, and an enlarged portion 2J1 is fixed to the left end.

2K is a fixing screw provided near the tip of the pipe body 2A so as to be movable toward the inside of the pipe body 2A.

3 is an insert member inserted from the left end of the horizontal member 2 into the horizontal member so as to be able to move forward and backward, and the pipe body 3
A, and an upward projecting piece 3B is fixed to the left end of the pipe body 3A, and a right end wall 3C is stretched from the right end of the pipe body, and from this right end wall 3C. In this case, the prismatic body 2J is penetrated.

c. Effect Explain along with the effects.

C. Effects of the invention Since this invention has the structure as described above, when using it, horizontal members 4A1 of the frame scaffolding 4, etc.
Hooks 2E and 2F to the pin holes H and H.
Pass pins 2I and 2I through.

Fasten the horizontal insert 3 to the required length position with the fixing screw 2K.

Therefore, unlike conventional carrying frames, it can be easily installed and removed without requiring any special tools.

Moreover, if the insertion material 3 of the horizontal material becomes a hindrance during construction, it can be easily retracted into the horizontal material 2 by loosening the fixing screw 2K, so that it does not become a hindrance during construction.
