Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold for construction used when constructing a building such as a unit house and a construction method thereof.

[0002]

2. Description of the Related Art When constructing a building, a scaffold is installed in front of the building so as to be located around the building for the purpose of ensuring safety and workability. Conventionally, this scaffold has been constructed by joining a pipe material with a clamp member at a construction site to form a framework and attaching a work floor to the framework. Therefore, there has been a problem that a lot of labor and time are required for scaffolding assembling work and dismantling work.

In order to solve such a problem, a scaffolding unit having a shape obtained by dividing the scaffold into a plurality of pieces is formed in advance, and the scaffolding unit is installed at a construction site to construct the scaffolding. It has been proposed (for example, see Japanese Patent Laid-Open No. 6-146570).

[0004]

However, in the conventional scaffolding for construction, the dimensions of the scaffolding are standardized, and the scaffolding units are constructed by directly connecting the scaffolding units adjacent to each other. For this reason, not only a large number of scaffolding units are required, but even when it becomes necessary to adjust the installation intervals or the installation positions of the adjacent scaffolding units depending on the size of the building to be built, etc. There was a problem that it was difficult to adjust. In addition, the scaffolding thus constructed may be too close to or far from the building in which it is built,
There was also a problem that the workability deteriorated.

The present invention has been made in view of the above circumstances. The number of scaffolding units used can be reduced, and the installation intervals and installation positions of the scaffolding units can be arbitrarily set according to the size of the building to be constructed. And can be adjusted,
It is an object of the present invention to provide a scaffold for construction that can improve workability and a method for constructing the scaffold.

[0006]

In order to achieve the above object, the scaffolding for construction according to claim 1 is arranged at predetermined width intervals in the scaffolding for construction installed around the building when constructing the building. It has a plurality of strut materials, horizontal members that are horizontally interposed between these strut members at a predetermined height interval, and a work floor that is hung between the horizontal members at a predetermined level, and is installed at appropriate intervals. And a connecting means that is provided so as to extend toward the scaffolding unit adjacent to the scaffolding unit and that connects the adjacent scaffolding unit to each other.

The construction scaffold according to claim 2 is the construction scaffold according to claim 1, wherein the connecting means is an auxiliary cross member provided on a cross member of the scaffold unit so as to extend and adjust in a longitudinal direction thereof. And a fixing member that is provided at the tip of the auxiliary horizontal member and is fixed to the horizontal member or the pillar member of the other adjacent building unit.

A construction scaffold according to a third aspect is the construction scaffold according to the first aspect, wherein the connecting means is provided on the work floor of the scaffolding unit so as to extend and adjust in the longitudinal direction of the scaffolding unit. And it is installed at the tip of this auxiliary work floor,
It is characterized in that it is composed of a lateral member of the other adjacent building unit, a pillar member or an engaging member that engages with the work floor.

A construction method of the scaffold for construction according to claim 4 is:
When building a building, a plurality of strut members arranged at a predetermined width interval, a horizontal member horizontally interposed between these strut members at a predetermined height interval, and a cross member between the horizontal members at predetermined intervals. Scaffolding units having a fixed work floor are installed at appropriate intervals along the perimeter of the building, and then they are adjacent to each other via connecting means provided in advance so as to extend toward the scaffolding unit adjacent to this scaffolding unit. It is characterized in that it is connected to the scaffolding unit.

[0010]

According to the construction scaffolding of claim 1, the scaffolding unit is provided with a connecting means extending toward the adjacent scaffolding unit to connect the scaffolding units to each other, and along the periphery of the building to be built. Since the scaffolding units can be installed at appropriate intervals, it is possible to reduce the number of scaffolding units used and to set the installation intervals and installation positions of the scaffolding units arbitrarily according to the size of the building to be built. Adjustments can be made and workability can be improved.

According to the construction scaffold of claim 2, an auxiliary cross member provided so as to be adjustable in its longitudinal direction is extended to a cross member of the scaffold unit, and the tip of the auxiliary cross member is extended. Since the provided fixing member is fixed to the cross member or the pillar member of the other adjacent scaffolding unit, the installation intervals of the adjacent scaffolding units can be easily adjusted while reliably connecting the two building units. It becomes possible.

According to the construction scaffold of the present invention, an auxiliary work floor, which is provided in the working floor of the scaffolding unit so as to be adjustable in the longitudinal direction thereof, is extended, and the auxiliary work floor is extended to the tip of the auxiliary work floor. Since the provided engaging portion is adapted to be engaged with the cross member, strut member or working floor of the other adjacent scaffolding unit, both scaffolding units can be easily adjusted while adjusting the installation interval of the adjacent scaffolding units. Can be reliably connected.

According to the method for constructing a scaffold for construction according to a fourth aspect, scaffold units which are formed in advance and provided with connecting means are installed at appropriate intervals along the periphery of the building to be constructed, and then the scaffold units are adjacent to each other. Since the scaffolding units are connected by extending the connecting means from one scaffolding unit to the other scaffolding unit, the number of scaffolding units used can be reduced and the scaffolding unit can be constructed according to the size of the building to be constructed, etc. It is possible to arbitrarily set and adjust the installation interval and the installation position of, and workability can be improved.
