Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a frame scaffolding constructed during construction work,
The present invention relates to a widening frame device (hereinafter simply referred to as a frame device) used for laterally extending the width of a scaffold from the middle of the height direction.

(Prior Art) Conventionally, the frame scaffolding used for the construction work requires a certain gap for mounting and dismounting the concrete formwork, and the outer wall surface has windows, balconies, eaves, etc. Since it has a protrusion, it is erected at a required distance from the building exterior wall line. However, when installing wall finishing, if there is the above-mentioned interval or space, it is very dangerous to cause an accident such as stepping off the foot during work and falling or injury from something dropped from the top. high.

In order to prevent these accidents and improve work efficiency, the width of the scaffold is extended from the middle in the height direction of the frame scaffold to the building side.

Various devices have been proposed for use for the above purpose, but a representative one is Japanese Utility Model Publication No. 54-66415. The scaffolding device according to this proposal is that "a bracket is inserted into the upper frame of the torii frame so that the bracket can extend and contract, the upper end of the cane is pivotally attached to the tip of the bracket, and the lower end of the cane is pivotally attached to the building frame of the torii frame. What I wore. "

(Problems to be Solved by the Invention) The scaffolding device according to the above proposal has the advantage that the bracket can be extended to an appropriate length according to the situation of the site of use, while the building frame 2 of the torii frame A is provided. Since the mounting bracket 10 at the lower end is fixedly attached to the scaffolding device, the torii frame A is necessarily attached to the scaffolding device, which inevitably increases the size.

In addition, the torii frame A is inevitably attached, and the cane has a double structure. Further, the bracket 5 is attached to the building frame 2 and the upper frame 1.
Since it is designed to be inserted into the device, the structure is complicated and the manufacturing is troublesome, and it requires a lot of man-hours, and there is a drawback that the cost becomes high.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems in the related art, and is equipped with mounting brackets that are detachably attached to the frame scaffold at the upper and lower ends of the frame device. Therefore, it is intended to solve the above problems.
