Abstract

(57) [Summary] [Purpose] To provide a support structure for a scaffold that can ensure the stability of the scaffold even when performing exterior work of a building. [Structure] A support member 1 which is removably fixed to a roof B of a building, and one end 2a is removably fixed to the support member 1 and the other end 2b is removably fixed to the top of the scaffold A. Since the connecting member 2 is provided, it is not necessary to remove the connecting member 2 when performing exterior work.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support structure for fixing a scaffold when constructing a building, and more particularly, to an improvement of a structure for supporting an external scaffold used in a two-story or three-story low-rise building.

[0002]

[Prior art]

 Generally, when building a scaffold on the side of a building, it is necessary to secure the stability of the scaffold. A reserve is taken in between to secure the scaffolding.

[0003] As the retainer, wall ties or rafters are used, one end of which is fixed to the scaffold and the other end of which is fixed to the side wall of the building.

[0004]

[Problems to be solved by the device]

 However, in such a method of fixing scaffolds, one end of the above-mentioned retainer is directly attached to the side wall of the building, so when performing exterior work such as attaching tiles to this side wall, One end of the copy must be removed from the side wall. As a result, the scaffolding is very dangerous because it may lose stability and collapse.

Therefore, the present invention has been made in view of such conventional problems, and the purpose thereof is to ensure the stability of the scaffold even when the exterior work of the building is performed. It is to provide a scaffolding support structure that can be.

[0006]

[Means for Solving the Problems]

 The scaffold support structure according to the present invention includes a support member removably fixed to a roof portion of a building, one end removably fixed to the support member, and the other end removable to the top of the scaffold. It is characterized by comprising a connecting member to be fixed.

[0007]

[Action]

 In the scaffold support structure according to the present invention, the top of the scaffold is supported by the supporting member provided on the roof portion of the building by the connecting member, and it is necessary to remove the connecting member even when performing exterior work. Absent.

[0008]

【Example】

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

A scaffolding support structure according to the present invention is shown in FIG. 1, and the scaffolding support structure is for connecting and fixing a scaffold A and a roof B of a building. It is prepared as the main part.

The scaffold A is formed by vertically and horizontally combining a plurality of scaffold pipes a, a ... And connecting and fixing them.

The roof B of the building is a folded plate roof, and a folded plate 4 made of a metal plate is supported on the upper surface of the beam 3 through a tight frame 5. As shown in FIG. 2, the tight frame 5 has an uneven cross-sectional shape substantially the same as that of the folded plate 4, and the lower surface of the concave portion 5a is welded and fixed to the upper surface of the beam 3 and the upper surface of the convex portion 5b. The bolts 6 are provided upright.

A folding plate 4 is arranged along the upper surface of the tight frame 5, and a nut 8 is fastened and fixed to the bolt 6.

The support member 1 is fixed to the roof B, and includes a mounting plate 11 and a support rod 12 provided on the upper surface of the mounting plate 11 upright as shown in FIG.

The mounting plate 11 is specifically an elongated metal plate, and a plurality of elongated holes 11a, 11a ... Are formed at predetermined intervals in the longitudinal direction. The elongated holes 11a, 11a ... Are arranged at positions where the bolts 6 protruding from the tight frame 5 can be inserted when the mounting plate 11 is brought into contact with the folding plate 4, and the elongated holes 11a, 11a. A plurality of types of arrangement intervals between the parts 11a and 11a are set so as to be compatible with various shapes of the folded plate 4.

The support rod 12 is for engaging the connecting member 2 with the support member 1, and is made of a metal cylindrical pipe provided integrally with the mounting plate 11. The diameter of the support rod 12 is substantially the same as the diameter of the pipe a forming the scaffold A.

The connecting member 2 is used to connect the scaffold A and the supporting member 1. Specifically, the connecting member 2 is made of a metal cylindrical pipe, and one end 2 a is detachably fixed to the supporting member 1. , The other end 2b is detachably fixed to the top of the scaffold A. A universal clamp 21 or the like is preferably used as the fixing fitting.

Next, a work procedure for fixing the scaffold A to the roof B 1 by using the scaffold support structure configured as described above will be described.

The supporting member 1 is brought into contact with the folding plate 4 while inserting the long holes 11a, 11a, ... Of the supporting member 1 into the bolts 6, 6 ,. The nuts 7, 7, ... Are tightened via washers 9, 9 ,.

At this time, since the long holes 11a, 11a, ... Of the supporting member 1 are formed with a plurality of types of installation intervals so as to be compatible with various folding plates 4, as described above, It can be easily inserted into the bolts 6 and 6 of the tight frame 5 that project.

Next, the universal clamp 21 is attached to the support rod 12 of the support member 1 to connect the one end 2a of the connecting member 21 and the support rod 12. Since the support rod 12 has substantially the same diameter as the scaffolding pipe a, the universal clamp 21 can be of the same standard as the universal clamp used for assembling the scaffolding pipe a. You don't need tools.

Finally, the other end 2b of the connecting member 2 and an appropriate pipe a at the top of the scaffold A are connected by a universal clamp 21 to complete the work of connecting the scaffold A and the roof B.

[0022]

[Effect of device]

 As described above in detail, according to the present invention, since the scaffold and the roof portion of the building are connected, it is not necessary to remove the connecting member even when performing the exterior work, and the exterior structure is the same as the conventional one. There is no danger of the scaffolding collapsing with the construction.

Further, the supporting member of the present invention can be applied as a tiger rope supporting member for stabilizing the installation of the rooftop TV antenna or the elevated water tank even after the completion of the construction work.
