BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestal for temporary scaffolding constructed inside a building in construction work such as a building.

[0002]

2. Description of the Related Art Conventionally, temporary scaffolds have been built around or inside a building in order to secure a scaffolding for a building worker in a construction work such as a building. Here, when securing a scaffold inside a building, for example, by using a steel frame of a building under construction, etc., both ends of the long or telescopic scaffold are directly fixed to the steel frame with clamps or the like and installed. I am doing it.

[0003]

However, recently, a construction method of placing concrete around the steel frame such as the SRC construction method is often adopted, and depending on the progress of the construction work, among the steel frames for constructing the scaffold, There is a case where only one steel frame is covered with concrete and becomes bulky. In that case, even if an attempt is made to construct a scaffold, it will not be horizontal due to a step, so there has been a demand for a solution to this problem.

In view of the above points, it is an object of the present invention to provide a scaffolding pedestal capable of horizontally laying a scaffolding even at a place having a step.

[0005]

In order to solve the above problems, the present invention provides a scaffolding cradle according to claim 1, wherein:
A pair of pillars standing upright in parallel is connected by a horizontal member to form a substantially gate-shaped frame body, and at the lower end of each pillar member of the frame body is horizontal and is arbitrary with respect to the horizontal member. Each of the base members is capable of being fixed at an angle, and both ends of the base member are provided with fixing means for fixing the base member to a steel frame or the like.

The scaffolding cradle according to claim 2 is characterized in that the fixing means is provided with a height adjusting function.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the scaffolding cradle of claim 1 of the present invention, for example, in a construction site of a building adopting the SRC method or the like, a steel frame covered with concrete and a bare steel frame When a scaffold is installed between the scaffolds, first, the scaffolding platform is placed on the exposed steel frame side so that the steel frame and the horizontal member are substantially parallel to each other.

Next, each base member is rotated with respect to the support member, and the clamps, which are fixing means provided at both ends of the base member, are adjusted so as to match with both side positions of the lower steel frame.
Then, fasten each clamp to the flanges on both sides of the steel frame,
Securely fix the base material to the steel frame. In this way, the locking member on one end side of the long or telescopic scaffold is locked to the horizontal material of the scaffolding base fixed on the bare steel frame, while the other end side of the scaffold is on the steel frame covered with concrete. To place. At this time, if the height of the horizontal member is set in consideration of the concrete coating thickness in advance, the scaffold to be erected can be installed more horizontally.

As described above, according to the scaffolding pedestal, it is possible to lay the scaffolding horizontally by a very simple work even in a place where there is a step due to cast concrete or the like. Can be provided.

Further, according to the scaffolding cradle of claim 2, since the fixing means for fixing the base material is provided with the height adjusting function, it is possible to adjust the horizontal material height of the scaffolding cradle and the place where the step is different. But you can always build a horizontal scaffold.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a scaffolding pedestal according to the present invention, which is a substantially gate-shaped frame body 4 composed of a pair of pillar members 2 standing in parallel and a horizontal member 3 connecting them, and a frame member 4 of the frame member 4. The main portion is composed of a base material 5 for supporting the frame body 4 provided at the lower end portion of each pillar material 2.

Each of the support members 2 is a steel member having a substantially L-shaped cross section, and as shown in FIG. 1, the support members 2 are arranged so that their planes face each other. Further, the horizontal member 3 is a cylindrical steel pipe that locks the locking clamp at the end of the scaffold A, and both ends of the horizontally arranged horizontal member 3 have a predetermined height of the planes facing each of the pillar members 2. The positions are fixed and connected to each other to form a substantially gate-shaped frame body 4. Here, the length of each support member 2 and the height position at which the horizontal member 3 is attached depend on the level difference of the place where the scaffold A is installed. Further, the length of the horizontal member 3 corresponds to at least the width of the scaffold A to be installed.

A substantially disk-shaped base plate 6 is fixed to the lower end portion of the column member 2, and a through hole for inserting a bolt is formed in the central portion of the base plate 6. Further, a through hole for inserting a bolt is also formed in the substantially middle portion of the base material 5,
The frame 4 and the base member 5 are fixed to each other by inserting the bolt 7 into the through hole of the base plate 6 and fastening the same. Therefore, the base member 5 can be freely adjusted at an arbitrary angle with respect to the horizontal member 3 by tightening and loosening the bolt 7.

Further, the base material 5 is provided on both ends of the base material 5.
Is provided with a clamp 8 which is a fixing means for fixing to the steel frame B of a building under construction. The clamp 8 is composed of a substantially U-shaped clamp body 9 that clamps flange portions on both sides of the steel frame B and a long bolt 10. The clamp body 9 is tightened and unfastened by a tightening operation of the long bolt 10. And the base material 5 for the steel frame B
A height adjusting nut 11 is provided for adjusting the height position of the.

Therefore, when the scaffold A of the present invention is used to lay the scaffold A between the steel frames B and B'having steps, such as a building which is a construction site, first the scaffold A is erected. The scaffolding pedestal 1 is placed on the exposed steel frame B of the steel frame. Next, the bolts 7 are loosened and the base materials 5 are rotated so that the clamp bodies 9 provided at both ends of the base material 5 are aligned with both side positions of the steel frame. Then, the clamp main body 9 is fitted into the flange portions on both sides of the steel frame B, fastened with the long bolts 10 to fix the base material 5 and the steel frame B, and then the bolts 7 are tightened to fix the frame body 4 and the base material 5. Fix it. At this time, if there is a step as compared with the steel frame in which the concrete is placed, the height adjustment nut 11 provided in the long bolt 10 is appropriately adjusted to eliminate the step.

In this way, the locking clamp at one end of the scaffold A is locked to the horizontal member 3 of the scaffolding pedestal 1 fixed on the steel frame B, while the other end of the scaffold A is made of concrete. Place the scaffold A on the floor and erect it horizontally. In addition,
If the scaffold A on the side of the steel frame B ′ is also fixed by a clamp or the like as needed, it can be fixed more reliably, which is suitable for work safety.

As described above, according to the scaffolding base 1 of the present invention, a scaffold can be installed horizontally by a simple operation even at a construction site where a step is likely to occur, and a safe and efficient working environment can be provided. .

[0019]

As described above, according to the scaffolding cradle of the first aspect of the present invention, a pair of pillar members standing in parallel are connected by a horizontal member to form a substantially gate-shaped frame. In addition, each of the supporting members of the frame body is provided with a base member that is horizontal and can be fixed at an arbitrary angle with respect to the horizontal member, and the base member is attached to a steel frame or the like at both ends of the base member. Since the fixing means for fixing is provided, a horizontal scaffold can be installed even in a place having a step.

Further, according to the scaffolding base of claim 2, since the fixing means is provided with a height adjusting function,
