Description

[Technical Field]

[0001] The present invention relates to a fireproof material support that supports a fireproof material that closes gaps between members that constitute a building structure. [Background technology]

[0002] For example, in architectural structures, fireproofing materials that seal gaps between H-beams and exterior wall materials are supported by fireproofing supports attached to the flanges of the H-beams. The fireproofing supports include, for example, base fittings, each of which has a plate-like support arm with a long hole attached to a base material such as a mesh material, and a mounting member that attaches the base fitting to the flanges of the H-beams (see, for example, Patent Document 1). More specifically, the mounting member is fixed by clamping the flanges of the H-beams and the base fitting between upper and lower clamping members that are connected vertically via the long holes in the support arms.

[0010] Below, as an embodiment of the present invention, an example of a fire-resistant material support device that covers the gap between steel beams and exterior wall materials in a steel-framed building structure and supports spray-applied fire-resistant material will be described in detail with reference to the drawings.

[0011] 1, the fireproof material support 100 covers the gap between a flange portion 201a (projection piece) of an H-shaped steel beam 201 serving as a structural member and a wall member 202, and is used to support fireproof material 203 that is sprayed on as a fireproof covering for the H-shaped steel 201. More specifically, as shown in FIGS. 1 and 2, for example, a base metal fitting 110 is placed on the underside of the flange portion 201a of the H-shaped steel 201, and the flange portion 201a and the base metal fitting 110 are clamped together by a clamp 120, thereby fixing them together.

[0012] As shown in Figures 3 and 4, the base metal fitting 110 is configured by welding a support arm 112 made of a metal plate and a core member 113 made of a deformed steel bar to a base member 111 such as metal lath. Slots 111a and 112a are formed in the base member 111 and the support arm 112 in a direction from the H-shaped steel 201 toward the wall member 202. That is, the support arm 112 is provided so as to cover the surrounding portion of the slot 111a in the base member 111. The core member 113 is provided along the slots 111a and 112a. A clamp insertion gap, through which a clamp 120 is inserted, is formed between the core member 113 and the inner peripheries of the slots 111a and 112a in the longitudinal direction.

[0013] 5 and 6, the clamp 120 is configured by screwing a butterfly bolt 124 (bolt) into a clamping member 121. The clamping member 121 is formed, for example, by bending a metal plate, and has a shape in which a pair of U-shaped clamping portions 122 are connected by a connecting portion 123. The butterfly bolt 124 is screwed into a female thread portion 123a formed in the connecting portion 123. Therefore, the clamping portion 122 of the clamping member 121 is inserted from bottom to top into the clamp insertion gap of the base fitting 110, and the abutment portion 122a is abutted against the upper surface of the flange portion 201a of the H-shaped steel 201, and the butterfly bolt 124 threaded into the female thread portion 123a of the connecting portion 123 is abutted against the lower side of the core material 113 of the base fitting 110, thereby clamping the flange portion 201a and the base fitting 110, thereby making it possible to fix the base fitting 110 to the H-shaped steel 201.

[0014] Here, although not essential, the clamping portions 122 of the clamps 120 are provided with protrusions 122b near the abutment portions 122a on the opposing inner surfaces, with the distance between them being slightly narrower than the thickness of the core material 113 of the base metal fitting 110. Therefore, prior to fixing the base metal fitting 110 to the H-shaped steel 201, the spacing between the protrusions 122b can be slightly widened so that the core material 113 of the base material 111 is sandwiched between the protrusions 122b and the connecting portion 123, thereby temporarily fastening the clamps 120 to the base metal fitting 110. This allows the base metal fitting 110 and the clamps 120 to be handled as a single unit, improving distribution and workability.

[0015] As described above, the base material 111 of the base fitting 110 is provided with the core material 113 extending in the direction from the H-shaped steel 201 toward the wall member 202. This facilitates increasing the rigidity and strength of the base fitting 110. Furthermore, by clamping the wing bolts 124 of the clamps 120 against the core material 113, the base fitting 110 can be securely fixed to the H-shaped steel 201. Furthermore, by inserting the abutment portion 122a of the clamping portion 122 of the clamp 120 into the clamp insertion gap of the base fitting 110 so that it can abut against the upper surface of the flange portion 201a, workability can also be easily improved. Furthermore, by forming the elongated hole 111a in the base material 111 and inserting the clamp 120 through it, the degree of freedom in the relative position of the clamp 120 and the base fitting 110 can be increased, making it easy to flexibly accommodate various distances between the H-shaped steel 201 and the wall member 202.
