Description

  The present invention relates to a fire-proof filler support fitting that receives and supports a fire-proof filler that is filled between an inner peripheral surface of an insertion hole that is formed through the housing and an insertion body that is inserted therethrough.

As shown in FIG. 24, the conventional filler support metal fitting 100 is inserted at the base end of the key-shaped hooking portion 101 that can be locked and fixed to the opening edge of the insertion hole B1, corresponding to the inner surface of the insertion hole. A leg portion 102 along the hole axis direction and a tongue piece portion 103 integrally formed with a tongue piece portion 103 extending from the tip of the leg portion 102 to the insertion hole B1 are provided with a pair of bases 104 having an L-shaped cross section. The receiving portion 105 has a length that can traverse the insertion hole in which a groove 105 a having a U-shaped cross section that can be inserted into the piece portion 103 is formed.
This filler support metal fitting 100 is inserted from the opening side of the insertion hole B1 in a state in which the tongue pieces of the base are inserted from both ends of the receiving part 105, so that the fireproof filler filled in the insertion hole B1. D is configured to be supportable. The thing applicable to the patent document of this prior art example was not found.

However, such a filler support metal fitting 100 is mounted corresponding to insertion holes of different sizes by aligning receiving portions having a plurality of types of lengths corresponding to the size of the insertion hole B1 to be mounted. Therefore, it is necessary to use a receiving portion having a length corresponding to the crossing length of the insertion hole at the construction site, and there is a problem that the compatibility at the construction site is poor.
Moreover, in the receiving part, it is the structure which uses an assembly | attachment component with a high manufacturing cost in the point etc. which are processed in the cross-sectional U shape, and there exists a problem that cost property is bad.
In addition, in this conventional filler support bracket, it is necessary to assemble a pair of foundation base and cradle together by screwing etc. at the construction site, and it is necessary to assemble in the state where the assembly labor and those assembled parts are aligned. There is a problem that handling is bad.
In addition, in this conventional filler support metal fitting, when the lengths along the through-axis direction of the insertion hole are different, it is necessary to use a base portion that is an assembly part including a leg portion formed in a corresponding length. Therefore, problems with poor on-site compatibility during construction have been pointed out.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a filler support metal fitting that can improve on-site compatibility and manufacturability, and is easy to use and handle. There is in point to do.

  The characteristic configuration of the first filler support metal fitting of the present invention is filled between the inner surface of the insertion hole and the insertion body inserted through the insertion hole in a state of crossing the insertion hole formed through the housing. Receiving part for receiving the fireproof filler, leg part extending along the through-axis direction of the insertion hole from both ends, and at least one leg end can be locked to the opening edge of the insertion hole A metal filler support metal fitting composed of a latching portion, wherein a plurality of portions in the longitudinal direction of the receiving portion are vulnerable portions that are plastically deformable along a direction intersecting the longitudinal direction. Is the point that is formed.

According to such a configuration, at least three weak portions are plastically deformed to deform the receiving portion into a folded state or a folded state, thereby bending the intervals between the leg portions provided at both ends of the receiving portion. It can be shorter than before.
Therefore, when the transverse length of the insertion hole to which the filler support metal fitting is attached is smaller than the length of the receiving portion, the receiving portion is bent to a length corresponding to the transverse dimension of the insertion hole or By performing the deformation operation in the folded state, the length can be changed to a length corresponding to the transverse dimension of the insertion hole to be mounted.
Further, since the fragile portion is directly formed in the receiving portion, it is possible to form a filler support metal fitting that can deform the length of the receiving portion with fewer parts.

Therefore, it is necessary to use an assembly part with a receiving part corresponding to the crossing length of the insertion hole to be mounted, and it is necessary to assemble a plurality of parts at the construction site compared to the conventional filler support bracket. Therefore, it is possible to change the length to the interval corresponding to the crossing length of the insertion hole at the construction site, so that it is easy to use and handle and the construction supportability of this kind of filler support bracket at the construction site is improved. Can do.
In addition, compared to conventional filler support metal fittings, for example, the receiving portion and the latching portion can be integrally formed from the same substrate such as a sheet metal, so that it can be manufactured at low cost. .
Furthermore, when the insertion body is inserted and cannot be mounted on the way the receiving part of the filler support metal fitting crosses, the filler support metal fitting can be divided into two parts by appropriately cutting the fragile part at a location, The divided filler support fitting can be mounted in a cantilever manner in the insertion hole.

The characteristic configuration of the second filler support metal fitting of the present invention is filled between the inner surface of the insertion hole and the insertion body inserted through the insertion hole in a state of traversing the insertion hole formed through the housing. Receiving part for receiving the fireproof filler, leg part extending along the through-axis direction of the insertion hole from both ends, and at least one leg end can be locked to the opening edge of the insertion hole A metal filler support bracket made up of a latching portion,
A plurality of weak portions that can be plastically deformed along a direction intersecting the longitudinal direction are formed at a plurality of locations in the longitudinal direction of the leg portions.

According to such a configuration, at least two weak portions are plastically deformed to deform the leg portion into a folded state or a folded state, thereby shortening the length of the leg portion in the longitudinal direction as compared to before bending. Can do.
Therefore, when the length along the through-axis direction of the insertion hole to which the filler support metal fitting is attached is smaller than the length dimension in the longitudinal direction of the leg portion, the length along the through-axis direction of the insertion hole The receiving part can be changed to a length corresponding to the length along the through-axis direction of the insertion hole of the insertion hole to be mounted by deforming the receiving part into a bent state or a folded state to a length corresponding to it can.

Accordingly, it is necessary to use an assembly part having a leg portion formed to have a length corresponding to the length along the through-axis direction of the insertion hole to be mounted and to assemble a plurality of parts at the construction site. Compared to the conventional filler support bracket, the length of the insertion hole along the axis of the insertion hole at the construction site can be changed according to the situation, so this type of filler support bracket is easy to use and handle. It is possible to improve the construction compatibility at the construction site.
In addition, for example, since the receiving portion and the latching portion can be integrally formed from the same substrate such as a sheet metal, it can be manufactured at low cost.

  According to the third aspect of the present invention, the fragile portion that is plastically deformable along the direction intersecting the longitudinal direction is formed at a plurality of locations in the longitudinal direction of the leg portion. In the point.

According to such a configuration, at least three weak parts are plastically deformed and the receiving part is deformed into a folded state or a folded state, whereby the distance between the legs provided at both ends of the receiving part is bent. The length of the leg in the longitudinal direction can be reduced by plastically deforming at least three weak parts and deforming the leg into a folded state or a folded state. Can be shortened.
Accordingly, at least one of the transverse dimension of the insertion hole or the length dimension in the direction along the through-axis line of the insertion hole is the length along the longitudinal direction of the receiving part of the corresponding filler support metal fitting or the penetration of the leg part. When the length is shorter than the length along the axis, the length along the longitudinal direction of the receiving portion corresponding to the length or the length along the penetration axis of the leg portion can be changed correspondingly.
Therefore, it is possible to attach the filler support fitting to the insertion hole appropriately corresponding to the transverse dimension of the insertion hole and the length along the through-axis direction of the insertion hole at the construction site. Can be improved.

  According to the fourth aspect of the present invention, the bridging support metal fitting has a fragile portion that is plastically deformable along a direction intersecting each longitudinal direction at the boundary between the leg portion and the latching portion. In the point.

  According to such a configuration, for example, by forming the filler support metal fitting in which the boundary between the leg portion and the receiving portion is previously bent by machining as a product form, the leg portion can be used at the construction site. The weakened portion formed at the boundary between the hook and the latching portion can be selectively plastically deformed and bent.

Therefore, for example, in the case of an irregular insertion hole in which one inner surface of the insertion hole is continuously formed on the wall surface or floor surface of the housing, one latching portion corresponding to the same surface side is provided. Can be attached to the insertion hole with the other latching part not bent to the leg along the wall or floor and the other weakening part plastically deformed and bent outward with respect to the leg. Can be.
In the case of a general insertion hole formed as a hole penetrating a wall or floor, the corresponding weakened part is plastically deformed and bent outward with respect to the leg part, and the insertion hole is formed. Can be made attachable to.
This makes it possible to form a filler support metal fitting corresponding to the shape of the insertion hole at the construction site, compared to a filler support metal fitting in which both latching portions are bent outward in advance. Even if it can be used corresponding to the insertion hole, only the support fittings corresponding to this can be used for irregular insertion holes in which the wall surface or floor surface and one inner surface of the insertion hole are formed flush with each other. Since there is no such thing as being impossible, it is possible to form a filler support metal fitting excellent in workability.

  According to the fifth aspect of the present invention, there is provided a characteristic configuration of the filler support metal fitting, wherein at the boundary between the receiving part and the leg part, a weak part capable of being plastically deformed is formed along a direction intersecting each longitudinal direction. There is in point.

According to such a configuration, by forming the filler support metal fitting in a flat plate shape in advance, it is formed at the boundary between the leg portion and the latching portion and at the boundary between the leg portion and the latching portion at the construction site. The fragile portion can be selectively plastically deformed and bent.
Therefore, since the boundary between the leg part and the latching part and the boundary between the leg part and the latching part can be handled in a compact manner, it can handle a large number of filler support metal fittings. It is possible to reduce the inventory space for this kind of product and to improve the activation and efficiency of transportation.
Moreover, at the construction site, by selectively plastically deforming the fragile part formed at the boundary between the leg part and the receiving part and the boundary part between the leg part and the latching part and bending it so that it can be attached to the insertion hole, Since the filler support fitting corresponding to both the general insertion hole on site and the irregular insertion hole can be formed, the workability can be improved.

  The characteristic configuration of the sixth filler support metal fitting of the present invention is that the fragile portion is formed by forming a through hole.

According to such a configuration, the fragile portion can be formed by a simple hole processing such as an insertion hole.
Therefore, the production is simple and the production cost can be improved.

  The seventh feature of the filler support metal fitting according to the present invention is that the base end portion of the latching portion has a leg portion and a latching portion so that the latching portion is displaced toward the receiving portion side rather than the tip end of the leg portion. It is in the point comprised by the inclination attitude | position with respect to the part.

  According to such a configuration, for example, the corresponding weakened portion formed in the receiving portion is plastically deformed and cut to divide the filler support bracket into two, and the opening edge of the insertion hole formed in the floor is formed. When used in a so-called cantilever mounting state in which the receiving part is arranged in the insertion hole by the latching part in which the divided support metal is locked to the opening edge of the insertion hole, the load of the receiving part The latching part is slippery from the edge of the opening, and if it receives unexpected external force such as contact with the hand during construction, the support bracket tends to slide down into the insertion hole. By configuring the base end portion of the latching portion in an inclined posture, the tip of the latching portion can intensively support the load of the catching portion and form a state in which it is difficult to slip from the opening edge.

  Therefore, in particular, when used as a filler support fitting divided into two parts, it is possible to prevent a sudden external force from being applied to the insertion hole in a temporarily fixed state and slipping down to the insertion hole. It is possible to improve the performance.
