Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a divided building frame member for assembling and constructing scaffolds mainly when constructing or repairing a multi-storey building.

[0002]

2. Description of the Related Art When constructing or repairing a building such as a high-rise building or a house, a scaffolding device is assembled along the building. Usually, such a scaffolding device uses a log with a wire. Since they are constructed in combination or constructed by adding and connecting metal pipes in the vertical and horizontal directions, not only enormous labor and time are required for their assembly, but also the assembly work is dangerous.

For this reason, in recent years, a folding type scaffolding device has been developed and has a length corresponding to the height of a floor to be constructed, as described in, for example, Japanese Utility Model Laid-Open No. 60-51243. And, the columns to which the brackets are attached at regular intervals are provided in front and behind at a predetermined interval, and a plurality of pairs of the opposing columns are arranged at predetermined intervals in the left-right direction and are adjacent to each other on the left and right. There is a structure in which scaffolding plates are provided in the space between columns in the vertical direction at regular intervals, and the square corners of each scaffolding plate are pivotally supported by the brackets of the columns facing the corners.

[0004]

However, according to the foldable scaffolding device as described above, the scaffold plate pivotally attached to the strut by suspending the strut arranged in the middle portion in the left-right direction is provided on both sides. You can fold the pillar by pulling it toward the pillar side of the middle part and rotating it downward, but since the pillar having the length corresponding to the height of the floor to be built is not folded, you can transport it Not only is it difficult to handle, but the buildings to be built have different heights such as middle and high rises, and scaffolds must be prepared according to the heights.

Further, the width direction of the building can be dealt with by changing the number of columns used in parallel in the left-right direction. In this case, in the folded state, the columns are arranged from the lower end of the column in the middle part to the most side parts. The stakes that have been installed will be in a folded state that protrudes significantly downwards, making it extremely long, and in addition, from the fold state, each of the stakes is unfolded in the left-right direction, and the front side of the building according to the width of the building. It is extremely difficult to assemble it in place.

Therefore, a narrow scaffolding device is constructed in which the central strut and both-sided strut are freely foldable through the scaffolding plate,
A plurality of such scaffolding devices must be assembled and assembled in the width direction of the building through the conventional assembling type scaffolding device, and there is a problem that significant labor and time are required for the construction work and the removal work after the construction. It was It is an object of the present invention to provide a split building frame member for scaffolding that can solve such problems.

[0007]

In order to achieve the above-mentioned object, the split building frame member for scaffolding construction of the present invention includes a pair of pillars having the same length, which are opposed to each other at a predetermined interval in the front-rear direction. A horizontal frame for supporting the scaffolding plate is integrally connected to form a building frame main body, and an upper bracket for joint is projected to one side at the upper ends of both pedestals of the building frame main body, while a joint is formed at the lower end. It has a structure in which the lower bracket for use projects toward the other side.

[0008]

A scaffolding device is constructed by combining a desired number of divided building frame members in the vertical and horizontal directions. At this time, in order to connect the divided building frame members in the vertical direction, the upper divided building frames are connected. The protruding direction of the bracket protruding from the lower ends of the two pillars of the member is made to coincide with the protruding direction of the bracket protruding from the upper ends of the two pillars of the lower split building frame member, and these brackets are drilled in the upper and lower brackets. The mounting holes are rotatably pivoted by pins or the like. In this way, a desired number of divided building frame members are connected in the vertical direction to form a building frame of a desired height, and such building frames are arranged side by side at predetermined intervals side by side, and the divided building frame members face each other. The both ends of the scaffolding plate are connected to the horizontal rod of the so as to be rotatable and detachable.

When the scaffolding device for construction is assembled in this way, the brackets of the divided building frame members connected in the vertical direction are oriented alternately in opposite directions in the projecting direction, so that the brackets are connected via the pivots. It becomes possible to bend in a zigzag shape, and the entire device is folded into a flat shape. When the uppermost divided building frame member is lifted by a winch or the like at the time of use, the divided building frame members are stretched in a straight line, and vertically adjacent divided building frame members are linearly formed by fitting a joint pin or the like. The scaffolding device is constructed by joining the two in a locked state.
