Description

The present invention relates to a wedge-shaped clamp with a wedge for saving the trouble of construction other than a right-angle portion by a wedge-shaped scaffold for construction that is made only for right-angle construction.

Conventionally, when constructing scaffolds in construction work, the existing ready-made wedge-shaped scaffolding material of Fig. 3 scaffolding support column 2 is designed for right-angle construction and refracted other than round buildings and right angles When it comes to the construction of a part of the building, there is only a method of tying the scaffolding material struts 2 to the same place in two places, and rotating the tieed scaffolding material struts 2 in the direction of the construction purpose to change the angle, In addition to the laborious work, there was a wasteful cost of having to use extra scaffolding material. And the length of the scaffolding strut 2 that is generally used is 3.6m and its weight is very heavy, about 13kg, so it takes harsh labor and working time, and it is dangerous because it becomes work at high place. It was work.

Also, the wedge type scaffolding material that is generally used is a conventional off-the-shelf product, and the wedge frames are fixed to the scaffolding column 2 by welding at a height of about 450 mm each in a perpendicular direction. The height of the floor and handrails has been decided, and there are many cases that you have to work with an unreasonable posture, and many injuries that hurt your back.
In order to solve the above problems, a search was made to find out if any good invention was filed, but it was not found. Therefore, trial and error experiments and research were conducted.

Patent Publication 2003-232128

The purpose of the present invention is to enable the construction of scaffolds at the angle and height according to the work purpose for the construction of circular buildings that take time when constructing scaffolds in construction work or the parts of buildings that are refracted other than at right angles In addition to reducing labor and labor, it is possible to set the work floor at the correct height so that workers using the scaffold do not have to work with an unreasonable posture.
Another object is to easily cope with the construction when there is a change in the scaffold construction at the construction site.

The present invention has been made to solve the above problems, and the invention according to claim 1 is a first aspect in which one or a plurality of groove-like recesses into which a wedge part of a wedge type scaffolding material is inserted are provided. A clamp having a U-shaped notch formed at the tip is pivotally supported at one end of the wedge frame, and a bolt is provided at the other end of the first wedge frame. While being pivotally supported, the tip of the bolt part is engageable with the U-shaped notch, and a nut is screwed to the tip of the bolt part. When the front end portion of the bolt portion is engaged with the U-shaped cutout portion to form an annular shape, the opening of the groove-like recess portion provided in the first wedge frame portion is inward. A wedge-shaped clamp with a wedge.

The invention according to claim 2 is characterized in that one or a plurality of groove-like recesses into which the wedge part of the wedge-type scaffolding material is inserted into the clamp are provided, and the tip part of the bolt part has the U-shape. The wedge-shaped clamp with a wedge frame according to claim 1, wherein an opening of the groove-shaped recess provided in the clamp is inward when engaged with the notch and formed into an annular shape. is there.

According to a third aspect of the present invention, there is provided a second one in which one or a plurality of groove-like recesses into which a wedge part of a wedge type scaffolding material is inserted are provided between the first wedge frame part and the clamp. One or a plurality of wedge frames are provided, and both ends of the second wedge frame are pivotally supported so that the front ends of the bolts are U-shaped notches. 3. The opening of the groove-shaped recess provided in the second wedge frame portion is inward when engaged with the second wedge frame. 4. This is a clamp with a wedge frame.

According to a fourth aspect of the present invention, the direction in which the wedge portion is inserted into the groove-shaped recess is along the direction of the pivot axis of the clamp. This is a clamp with a wedge frame.
According to a fifth aspect of the present invention, the direction in which the wedge portion is inserted into the groove-shaped concave portion is substantially perpendicular to the direction of the pivot axis of the clamp. A wedge-shaped clamp with a wedge as described in 1.
The construction scaffolding struts 2 and the wedge type scaffolding materials 2f are fixed to the circular part of the scaffolding pipe at the angle and height according to the work purpose by tightening the bolt part 1c and the nut 1d.
