Abstract

PURPOSE:To enhance the efficiency of the work of assembling and decomposing framed scaffolds by installing framed scaffolds at an interval of one span along a projecting curved external wall, and connecting the respective outside portions of adjacent framed scaffolds to each other by means of crossed braces, and connecting the respective inside portions of adjacent scaffolds to each other by means of a single pipe. CONSTITUTION:Plural sets of framed scaffolds A are installed along a curved external wall with an interval of one span determined by an outside portion serving as a reference. Adjacent framed scaffolds A are connected at their respective outside portions to each other by crossed braces 3b and connected at their respective inside portions to each other by a single pipe 5 via an orthogonal clamp 11. Scaffolds boards 2 are installed between adjacent framed scaffolds A and a curing sheet 7 and a wire-gauze curing frame 8 are installed. Thereby the work of assembling and decomposing the framed scaffolds is efficiently and safely carried out.

[Problem to be solved by the invention]

In the above conventional example, compared to a normal straight external framework scaffolding that is assembled along a flat external wall, the building frames 1, 1
In addition, a large number of eyeglass clamps 4 are required to connect adjacent frame scaffolds A and A, and in addition, in order to close the triangular space B that occurs between adjacent frame scaffolds. , an accessory scaffolding board 6, an accessory curing sheet 9, an accessory curing frame 10, etc. are required, which not only increases the cost, but also
It took time to assemble and disassemble, and there were also problems in terms of safety and efficiency.

An object of the present invention is to solve the problems of the conventional example.

[Means to solve the problem]

The technical means taken by the present invention to achieve the objective stated in -1- are as follows. That is, the external framework scaffolding for curved external walls according to the present invention consists of building frames erected at predetermined intervals C, scaffolding boards erected on the -F horizontal rod portions of these building frames, and both inside and outside sides. At the section, multiple sets of one-span, multi-tiered frame scaffolding consisting of cross braces stretched in an X-shape between the building frames are installed along the convex curved outer wall for one span with the outside part as the reference. The outer parts of adjacent frame scaffolds are connected with cross braces, and the inner parts are connected with a single pipe, while scaffold boards are erected between the scaffold boards of adjacent frame scaffolds. It is characterized by the fact that

[Effect]

According to the above configuration, when assembling an external framework scaffold for a curved exterior wall along a convex curved exterior wall, multiple sets of framework scaffolding with multiple tiers of one span are assembled, one span at a time based on the outside part. Since they are installed at intervals, the required number of building frames is approximately halved compared to conventional external frame scaffolding for curved external walls.

Since the span at the outside of external framework scaffolding for curved external walls is constant, ready-made products with standard dimensions can be used as the curing sheet and curing frame, and ready-made products with the same dimensions can be used for all scaffolding boards. .

It is a multi-tiered framework scaffold. W is a convex curved outer wall.

As shown in the figure, the external framework scaffolding for a curved exterior wall is constructed by installing multiple sets of the framework scaffolds A along the curved exterior wall W at intervals of 1 span (7) with the outside part as a reference. ,

〔Effect of the invention〕

Since the present invention has the above-described configuration, it can achieve the following effects.

■When assembling an external framework scaffold for a curved exterior wall along a convex curved exterior wall, multiple sets of framework scaffolding with multiple tiers of one span are installed with spaced intervals for each span based on the outside part. Therefore, compared to conventional external frame scaffolding for curved external walls, the required number of building frames can be roughly halved, and since the span on the outside is constant, there are no need for curing sheets, curing frames, or scaffolding. A ready-made product with standard dimensions can be used as the board, and the conventionally required eyeglass clamps, accessory curing sheets, accessory curing frames, accessory scaffolding boards, etc., become unnecessary.

■As mentioned above, the number of component parts is reduced, and the need for auxiliary work on the outer surface using equipment curing frames, etc., is reduced, so assembly and disassembly work can be carried out efficiently and safely, reducing costs. It is also advantageous, and the aesthetic appearance as an external scaffold for curved external walls is also improved.
