Problems solved by technology

[0030] In this braced connector 30, since the wedge metal fittings 2b joined to both ends of the horizontal member 31 are located at a high place, it is difficult for the operator to reach it with the hands of the wedge 2a during the fastening operation. Not only is it difficult to fasten and join the wedges 2a with the hammer 36, but there are also four wedge metal parts 2b and 30b in total, so there is also a cost for fastening and joining with the hammer 36 to drive the wedges 2a and 30a. work such a problem

Embodiment 1

[0086] Figure 10 It is an example of the connector with braces of the present invention. Figure 10 (a) is the front view. Figure 10 (b)~ Figure 10 (d) is an enlarged view of part A, where, Figure 10 (b) represents the left side view, Figure 10 (c) represents the front view, Figure 10 (d) shows a bottom view.

[0087]The braced connector 30 includes a horizontal member 31 made of a pipe made of steel, aluminum, or the like, and two braces 32 that support the horizontal member 31 from obliquely below. The ends of the horizontal members 31 are respectively joined with end plates 40 having notches 40a opening downwards by welding etc. The end portion of the horizontal member 31 can be connected to the pillar member by being hooked to the pillar member. On the other hand, a wedge metal fitting (Japanese: クサビ fitting) 30b is provided at the lower end of the brace 32 by welding or the like, and the wedge metal fitting 30b is hooked to a stopper ( Japanese: コマ) and othe...

Embodiment 2

[0108] Figure 18 is another example of the connecting piece with braces of the present invention. Figure 18 (a) is the front view. Figure 18 (b)~ Figure 18 (d) is an enlarged view of part A, where, Figure 18 (b) represents the left side view, Figure 18 (c) represents the front view, Figure 18 (d) shows a bottom view. in addition, Figure 19 It shows the state (front view) after connecting this connector with a brace to the side surface of the pillar member 3. FIG.

[0109] This long braced connector 30 differs from the braced connector of Embodiment 1 only in that the horizontal member 31 is longer. Therefore, similar to the short braced connector shown in Example 1, as the braced connector connected between the pillar members, even if not four places are fastened with wedges, even if the horizontal member Instead of being fastened and joined by wedges, the two ends of the two ends are hooked to the pillar members, and the connector with braces can also be firml...

Embodiment 3

[0111] Figure 20 is another example of the connecting piece with braces of the present invention. Figure 20 (a) is the front view. Figure 20 (b) is an enlarged left side view of part A, Figure 20 (c) is an enlarged front view of part A.

[0112] The braced connector 30 includes a horizontal member 31 made of a pipe made of steel, aluminum, or the like, and two braces 32 that support the horizontal member 31 from obliquely below. Button pins 41 are joined to ends of the horizontal member 31 via end plates 40 , and the ends of the horizontal member 31 can be connected to the pillar members by hooking the ends of the horizontal member 31 to the pillar members. On the other hand, a wedge metal fitting 30b is provided at the lower end of the brace 32 by welding or the like, and the wedge metal fitting 30b is hooked to a connecting metal fitting such as a stopper provided on the side surface of the pillar member and then driven into it. The wedge 30a can securely couple the ...

Abstract

[Problem] To provide a tie member which can be easily connected to support members with reduced work and can be firmly connected to the support members, and a temporary scaffold having the tie member installed therein. [Solution] A strut-equipped tie member comprising a horizontal member and two struts for supporting the horizontal member from obliquely below, and characterized in that engagement means for engaging the horizontal member with the support members are provided to both ends of the horizontal member and that wedge fittings are provided to the lower ends of the struts.

Description

technical field [0001] The present invention relates to connectors (Japanese: つなぎ材) used in temporary scaffolding used indoors and outdoors in construction sites such as construction sites and civil engineering sites, especially wedge-fastened combined scaffolds and system brackets, and A temporary setting scaffold made by assembling the connector. Background technique [0002] Temporary scaffolding at the construction site includes frame scaffolding used only for building construction, single-pipe scaffolding mainly used for residential construction, etc., and system brackets (also called Formwork support), rolling tower is also a form of temporary scaffolding. [0003] For example, in temporary scaffolding, there is a type (wedge fastening combination type) that uses a pillar member with connecting metal fittings such as stoppers on the side and a shorter connector (sometimes the shorter connector is specifically called a bracket material). Scaffolding), types of constru...
