Formwork separator mounting hardware

Abstract

To provide a metal fitting for attaching a stopper frame, an opening frame, etc., which are attached in a direction perpendicular to a concrete pouring form attached in parallel, to a separator so that the stopper frame or opening frame can withstand the self-weight pressure of the concrete. [Solution] Metal fitting 1 is formed in a U-shape for the purpose of hooking it perpendicularly onto separator 6 attached to formwork, with through-hole 3 drilled on one side and female screw hole 2 on the other. After hanging it on separator 6, separator 7 is screwed into female screw hole 2 from the through-hole 3 side, and metal fitting 1 and separator 7 become one piece. By attaching the integrated separator 7 to a retaining frame or the like, it can withstand the pressure of the concrete's own weight, which helps improve work efficiency and save on materials.

Description

[Technical Field]

[0001] This invention is a metal fitting attached to a separator oriented at a right angle, utilizing the bending stress of the separator, both ends of which are fixed and attached to a concrete formwork. [Background technology]

[0002] Conventionally, methods for holding formwork edges, gable frames, opening stop frames, etc. have involved pipe supports, wood, or a combination of chains and turnbuckles, which required materials, transportation, and installation work. [Prior art documents]

[0007] Mito 62-007547 Summary of the Invention [Problem to be solved by the invention]

[0008] The only way to deal with this is to reinforce the ends of the formwork, stop frames, opening frames, etc. with support pipes, chains and turnbuckles, wood, etc. to make them withstand the pressure of the concrete being poured, which is a heavy burden in terms of both labor and materials, and also poses problems such as making it difficult to ensure safe passage after use.

[0009] Separators are attached to formwork erected in parallel to withstand the pressure of the concrete raw materials and to maintain spacing and precision. This device utilizes the bending stress of the separator, which is fixed at both ends, and is attached at right angles by inserting and screwing in separators that will not come off even with any impact. It is a separator attachment hardware for supporting ends, stop frames, opening frames, etc. Effects of the device

[0010] As mentioned above, the stop frames etc. installed using this invention can withstand the pressure of pouring concrete, which not only reduces the amount of materials used and improves work efficiency, resolving labor shortages, but also eliminates the need for support pipes, turnbuckles and chains, thereby ensuring safe passage.

[0012] As shown in Figure 1, this metal piece is made of a metal plate processed into a U-shape that holds the hook separator 6, with a through hole drilled on one side and a female screw hole drilled on the other side. [Example]

[0013] An embodiment will be explained below with reference to the attached drawings. The device 1 is inserted into the hook separator 6, and the mounting separator 7 is passed through the through hole 3 and screwed into the female screw hole 2, so that the separator 6 will not come off from the main body 1 even if subjected to any impact. 4 is a tongue piece that prevents the hook separator from returning, and 5 is a folding claw that reinforces the part with the female screw hole.

[0014] The original way to use a separator is as shown in Figure (j) 6, and its purpose is to prevent the formwork from collapsing due to the lateral pressure of the concrete raw materials entering the formwork and to maintain dimensional accuracy. This device 1 is a metal fitting that is used to support the bending stress of the separator held at both ends, in addition to the tensile strength of the separator 6. By using it in a way that does not cause tensile fracture, it can be given a bending stress of about 10% of the allowable tensile strength, ensuring that it can be used in small areas such as ends, opening frames, and stop frames.

[0015] In one embodiment of the present invention, the purpose is to reduce the concentration of bending stress on the separator 6, so the width of the part that hangs on the separator 6 is planned according to the length of the separator 6, and the thickness of the metal plate formed into a U-shape is made thick enough to withstand deformation due to weight.
