Description

[Detailed description of the invention] This invention is used at construction sites where steel frames are assembled sequentially starting from the lower floors, and is designed to fit deeply into the front wall of a setting piece fixed to a steel frame building under construction, and to be fixed to the side wall of the setting piece. New construction for sequentially assembling scaffolding around the outside of construction work where bolt holes for fixing the upright pipes of the construction scaffolding with U bolts and pipe supports for placing the horizontal pipes of the construction scaffolding have been installed. This invention relates to an original sliding bracket for architectural scaffolding.

Exterior scaffolding in conventional high-rise buildings is installed on the entire surface in accordance with the steel frame that is planned to be constructed in advance, which inevitably requires a large amount of installation material cost and requires a lot of time for installation work.

In view of the above-mentioned drawbacks, the present invention was developed by embedding bolt anchors for fixing the setting piece in the top side of the side wall of the floor where construction has been completed at a construction site where the steel frame is being assembled sequentially from the lower floor, and the setting piece is attached to this bolt anchor. A box frame-shaped setting piece is fixed to the building by screwing together the bolts, and then a notch is cut to fit externally into the front wall of the setting piece, and a bolt hole is fixed to the side wall of the setting piece. The outer scaffolding is supported by a setting plate that has bolt holes for fixing the rising pipes of the architectural scaffolding with U-bolts and pipe supports for placing the horizontal pipes of the architectural scaffolding. To provide a sliding bracket for architectural scaffolding, which allows surrounding scaffolding to be lifted up by a crane, and the scaffolding to be sequentially set upward onto a steel frame under construction using a setting piece and a setting plate again.

An example of implementing the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a box frame-shaped setting piece that connects the steel building A under construction and the setting plate 2, and is fixed with bolts 4 to bolt anchors 3 buried in the concrete of the steel building A. . This setting piece 1 is made of a relatively thick steel plate, and has an insole 5 attached thereto.

As shown in FIG. 2, the setting plate 2 has a notch 6 that fits deeply into the front wall of the setting piece 1 and is inclined slightly outwardly (approximately 92 degrees in the embodiment) so that the setting plate 2 can be attached to the thickness of the setting piece 1. A fitting guide 7 is cut in the inner corner part which is cut to be slightly wider than the other side and is fitted into the setting piece 1, and a bolt hole 9 for fixing the bolt 8 to the side wall of the setting piece 1 is provided. It is perforated.

The outer side of the setting plate 2 that is fitted onto the setting piece 1 is longer than the inner side, and has a large fitting guide 10 cut in its lower part, and the inner riser pipe 11 of the outer scaffold B.
Bolt holes 13 for fixing with U-bolts 12 are drilled across several stages (four stages in the example), and the outer rise pipe 14 of the outer scaffold B is located at the tip of the shortened overhang. Bolt holes 15 for fixing with U-bolts 12 are drilled oppositely in two stages, upper and lower, and pipe supports 17, 17 for mounting the horizontal pipes 16 of the outer scaffolding B are attached to one side of the upper surface, respectively. There is. Numerals 18 and 18 are tightening nuts for each U-bolt 12.

19 is an adjustable swing stopper installed between the outer surface of the steel building A and the rising pipe 11 of the outer scaffolding B;
C is a panel formwork.

The sliding bracket for architectural scaffolding constructed as described above first attaches the setting piece 1 to the bolt anchor 3 buried in the steel building A.
The setting piece 1 is fixed to the steel building A by screwing together the bolt 4 from the inside. Next, attach the setting plate 2 to the front wall of the setting piece 1.
Insert the notch 6 externally. At this time, depth of cut 6
Fitting guides 7 and 10 are formed at both lower ends of the
Moreover, since the notch 6 is not at a right angle but is inclined slightly outward and is slightly wider than the thickness of the front wall of the setting piece 1, the fitting and insertion of the setting plate 2 can be carried out extremely smoothly. Also,
The setting plate 2 externally fitted and fixed to the front wall of the setting piece 1 is supported horizontally and firmly using the symmetrical positions of the inside and outside of the notch 6 as fulcrums a and b. Next, the side wall of the setting piece 1 and the setting plate 2 are fixed with bolts 8 at the positions of the bolt holes 9, and the installation work of the setting plate 2 is completed. Next, rise pipe 1
1 and 14 with U-bolts 12 and tightening nuts 18, the horizontal pipe 16 is placed on the pipe support 17, and the swing stopper 19 is installed, and the work of assembling the outer scaffolding begins.

The outer scaffolding B assembled in this way is usually supported by setting plates 2 at both ends, but depending on the width of the steel building A, it is possible to assemble a plurality of scaffolds, such as two or three, adjacent to each other. There are also many. In this case, as shown in Fig. 5, the setting plates 2, 2 of each scaffold are inserted into the setting piece 1 positioned between each scaffold.
Both plates 2, 2 are fixed to the setting piece 1 with bolts 8.

As described above, the sliding bracket according to the present invention has an extremely simple structure, is easy to handle, is highly safe, and is suitable as a connecting member for the outer scaffolding of a steel building under construction. . In particular, because scaffolding around the exterior of high-rise buildings can be installed economically with a small amount of equipment, costs and work time can be significantly reduced compared to conventional scaffolding installed around the entire area to match the steel frame to be constructed. It is something that can be done.
