Abstract

(57) [Summary] [Problem] To enable welding of a separator without damaging the reinforcing steel of a structure. [Solution] A separator weld metal is attached to a reinforcing bar to which a separator is to be attached, and the separator is welded to the metal body, thereby preventing damage to the reinforcing bar, quality control, and cost reduction.

Description

[Detailed description of the invention]

[Problems to be Solved by the Invention] Separators for supporting a mold are stabilized by pulling each other. Normally, it is one piece, but depending on the shape and dimensions of the structure, the separator can be long, so it is very difficult to construct with one piece. When the work procedure is taken into consideration, the formwork is assembled after the completion of the assembling of the reinforcing bars, which hinders the reinforcing bars themselves, making it difficult to install the separator. Some workplaces accepted that the separator was directly welded to the rebar and ignored the quality of the rebar, which originally intended to supplement the tensile strength of the concrete.

[Means for Solving the Problems] In order to solve the problems described above, a hardware for protecting the reinforcing bar itself has been devised. As shown in Fig. 1, the hardware is divided into two parts (1) and (2), and the metal (3) is sandwiched between (1) and (2) with the spacing of the separator (4) and the nut. The mounting position of the hardware at the time of tightening is determined by the reinforcing bar shape and the length of the separator to be welded. After the metal fitting is completed, the fillet welding (5) of the separator (4) is performed on the metal (1). Thereby, it can be constructed without damaging the rebar.

[Effects of the Invention] In order not to affect the quality of the rebar, it is considered that there is no problem in the rebar inspection and the strength is sufficiently secured. In addition, the work efficiency is good, and compared to the conventional method, material costs and labor are reduced, leading to cost reduction. The rebar diameter can correspond to D13 mm to D25 mm.

[Problems to be solved by the invention]

 The separator for supporting the formwork is stable by pulling each other, and is usually one piece. However, depending on the shape and dimensions of the structure, the separator can be long, so it is very difficult to use one piece. Will be difficult. When the work procedure is taken into consideration, the formwork is assembled after the completion of the assembling of the reinforcing bars, which hinders the reinforcing bars themselves, making it difficult to install the separator. Some workplaces accepted that the separator was directly welded to the rebar and ignored the quality of the rebar, which originally intended to supplement the tensile strength of the concrete.

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, a hardware for protecting the reinforcing bar itself has been devised. As shown in Fig. 1, the metal parts are divided into two parts (1) and (2), and (1) and (2) are sandwiched between rebars (3) opposed to the spacing of the separator (4), and the nuts are fixed with nuts. The position of the metal fitting at that time is determined by the shape of the reinforcing bar and the length of the separator to be welded. After the metal fitting is completed, the separator (4) is fillet welded (5) to the metal (1). Thereby, it can be constructed without damaging the rebar.

[Effect of the invention]

 Since it does not affect the quality of the rebar, there is no problem in the rebar inspection and the strength is considered to be sufficiently secured. Also, the work efficiency is good, and material costs and labor are reduced as compared with the conventional method, leading to cost reduction.

[Utility model registration claims]

1. A metal member for preventing a separator from being welded to a reinforcing bar when assembling a formwork. 50m width
m, holes of 25 mm in diameter are made at intervals of 70 mm in a 4 mm thick steel strip (SS material), and 9 m is provided between the holes of 25 mm.
Two holes of m were drilled. Next, the steel strip is cut at the center of the 25 mm hole, the cut surface is bent inward, and a reinforcing bar (SD material)
Was sandwiched. "Fig. 1" The above hardware is attached to a reinforcing bar, and a U-shaped bolt (SR material)
"Fig. 2" is inserted into a 9mm hole, tightened evenly with a hexagon nut, and retightened with an impact driver or the like. Next, a separator (SS material) is adhered to the top end of the hardware “FIG. 1”, and fillet welding is performed. Since there is no direct welding to the rebar,
It also keeps the rebar quality. ────────────────────────────────────────────────── ───
