Description

According to the present invention, a flooring fixture for fixing a long flooring material having a concave groove on a side surface, which is called a deck material, to a base material using the concave groove, more specifically, a screw. Fixing consisting of a combination of a fixing bracket that directly presses and fixes the flooring material by tightening and a resin support leg that is fixed to the lower surface side of this fixing bracket and maintains an independent state when the fixture is temporarily placed on the base material. Regarding the ingredients.

In particular, the present invention improves the strength of the fixing bracket, prevents damage to the support legs during transportation, and further prevents rusting even in the case of a base material using a metal pull-out. It is intended to provide ingredients.

When constructing a deck to be attached to a building, etc., use a flooring material with concave grooves on both sides in the length direction, and attach this flooring material to the base material such as joists and large pulls with fixtures and screws. The method of fixing using is known.

Conventionally, in the above-mentioned construction method, a fixture widely and generally used for fixing a flooring material on a base material is attached to a metal plate fixing bracket and the lower surface of the fixing bracket as in Patent Document 1. The fixing bracket consists of a combination of support legs made of synthetic resin, and is provided with a rectangular top plate having a screw insertion hole at an intermediate position and a top plate that is provided so as to bend downward from both long edges of the top plate and is adjacent to each other. It is formed of a pressing portion for fitting into the concave groove of the flooring material to be used, and a pair of legs that are continuous from both ends in the length direction of the top plate and bend downward.

Further, the support legs are composed of an arm plate that is mounted on the back surface of the top plate of the fixing bracket and a pedestal that projects downward from the center portion of the lower surface of the arm plate at a predetermined height dimension. A vertical hole for communicating with the screw insertion hole is provided so as to penetrate the lower surface of the pedestal.

The pressing portion of the fixing bracket is formed to have a length required to secure the fixing strength of the floor material when the lower surface is pressed by being positioned in the concave groove of the floor material, and both ends of the top plate are formed. In order to stabilize the independence in the length direction of the fixture, the leg body is integrally punched from the material metal plate and bent. However, when the length of the top plate is adjusted to the length of the pressing portion, Since the material metal plate is used longer due to the provision of the leg body, the length of the top plate of the conventional fixing bracket is shorter than that of the pressing portion, and the leg body is coupled to the end portion thereof. By doing so, we are trying to reduce the amount of material metal plate used, and as a result, both ends of the fixing bracket have a bifurcated structure with the end of the pressing part protruding from both sides of the end of the top plate. ..

Further, the support legs are intended to stand on their own when the fixture is temporarily placed on the base material, and the pedestals are provided with a pair of elastic legs that can be opened on both sides of the lower end portion, and the pedestals and the elastic legs are elastic. The total height of the legs is set so that the legs of the fixing bracket float slightly from the base material while the elastic legs are in contact with the base material, and the fixture placed on the base material is placed in the width direction. It will be stable and independent.

In order to attach this support leg to the fixing bracket, the arm plate is set to the same length as the pressing portion, and both ends are elastically fitted to the root portion of the leg body. A notch is provided to form a bifurcated shape, the arm plate is overlapped on the lower surface of the top plate in the length direction, and the locking notch is fitted onto the base of the leg to lock the heaven. The support legs are fixed to the fixing bracket with the vertical holes aligned with the screw insertion holes of the plate.

In order to construct a deck using the above-mentioned fixtures, the fixtures are placed on the upper surface of the base material on which the floor material is placed, and one pressing part of the fixing bracket is fixed to the base material in advance. The elastic legs are temporarily placed on the base material by fitting them into the concave groove of the base material, and then the vertical screws set in the vertical holes of the support legs are screwed into the base material from the screw insertion holes. Temporarily fix the fixture to the base material.

After that, a new flooring material is arranged in parallel next to the flooring material, the lower portion of the concave groove on the other side surface is fitted between the other pressing portion of the fixing bracket and the base material, and the screw is finally tightened in this state. As a result, the pressing part of the fixing bracket presses the lower surface of the concave groove to fix the flooring material to the base material. At this time, the elastic legs are opened so that the legs of the fixing bracket are seated on the base material. The deck is constructed with a large number of parallel flooring materials by being pushed out and repeating such parallel arrangement of flooring materials and fixing work to the base material using fixtures and screws.

Such fixtures can be temporarily fixed on the base material in a stable and stable state, and can be fixed by screwing from above with a single screw, so the flooring can be easily fixed and the deck can be fixed. In the built state, insert a tool through the gap between the flooring materials to loosen the screw, and with this tool you can move the fixture along the length direction of the recessed groove and take it out from the end of the recessed groove. If one of the flooring materials in the above is damaged, there is an advantage that only this one flooring material can be removed and replaced.

By the way, in the conventional fixture as described above, legs are provided at both ends of the top plate of the fixing bracket to assist independence in the length direction of the fixture. From the viewpoint of reducing the amount of metal plate used, the top plate is set shorter than the pressing parts on both sides, and the legs are bent downward from the end of the top plate, so from both sides of the end of the top plate. The end of the pressing portion protrudes, and therefore, both ends of the fixing bracket have a structure in which the both ends are greatly opened in two.

As described above, when both ends of the fixing bracket are open in two, the supporting leg is combined with the fixing bracket, and the locking notch of the arm plate on the supporting leg is externally fitted and locked to the root portion of the leg body. When the fixtures are assembled, the end of the arm plate is exposed so as to protrude from the end of the top plate to the bifurcated portion. Therefore, when a plurality of fixtures are packed at the same time during transportation, etc. When an external shock or vibration is applied, the metal fixing bracket may collide with the end of the arm plate in another fixture, and since the arm plate is made of synthetic resin, the fixing bracket collides. Then, the end of the arm plate will be scratched or broken, and there is a concern that the commercial value of the fixture will be reduced or the product will be defective.

Further, the total length of the pressing portion of the fixing bracket is formed to the length required for pressing and fixing the flooring material, but if the end portion has a structure protruding from the end portion of the top plate, this protruding end The pressing strength of the flooring material of the part will decrease, and when the fixture is used, if the base material is a large pull made of steel, the attractive force of the screw when tightening and fixing the flooring material is strong, so the pressing The protruding end of the portion will inevitably bend, leading to a decrease in the flooring fixing force.

Further, in the structure in which the downward legs are provided from one material at both ends of the fixing bracket, the reduction of the material metal plate when the top plate is made shorter than the pressing portion to form the legs is taken into consideration. Since the leg body needs to reach the base material from the lower surface of the concave groove of the floor material, there is a limit to the reduction of the material metal plate in the structure in which the leg body is provided integrally with the fixing bracket, and the metal leg The structure that assists the body to stabilize its independence in the length direction of the fixture during temporary placement is such that the rust-preventive layer of the base material is damaged because the leg body is expanded when it is seated on the base material. Therefore, there is a problem that rust is generated on the base material, which causes inconvenience especially when the deck is constructed outdoors.

Therefore, an object of the present invention is to eliminate the leg body with respect to the fixing metal fitting, thereby eliminating the decrease in commercial value and the occurrence of defective products due to scratches or breakage at the end of the arm plate, and the pressing portion of the fixing metal fitting. It is an object of the present invention to provide a flooring fixture that can eliminate a decrease in the flooring fixing force and does not cause rust on the base material.

In order to solve the above-mentioned problems, the invention of claim 1 is provided with a rectangular top plate having a screw insertion hole at an intermediate position and a top plate so as to bend downward from both long edges of the top plate.

Each arm plate locking portion provided on the top plate of the fixing bracket is a punched hole provided on the top plate and a position near the end in the length direction on the top plate at the periphery of the punched hole, or on the top plate. It is provided at one of the positions of one side edge in the width direction, and a part of the metal plate corresponding to the punched hole is formed by a locking claw bent toward the lower surface side of the top plate. ..

The invention of claim 2 is a rectangular top plate provided with a screw insertion hole at an intermediate position, and is provided so as to bend downward from both long edges of the top plate, and is provided in a concave groove of an adjacent floor material, respectively. A fixing bracket formed by a pressing portion for fitting, an arm plate to be mounted on the back surface of the top plate of the fixing bracket, and a self-supporting arm plate protruding downward from the center of the lower surface of the arm plate at a predetermined height dimension. A flooring fixture having a pedestal and a resin support leg provided with a vertical hole for communicating with the screw insertion hole so as to penetrate from the upper surface of the central portion of the arm plate to the lower surface of the pedestal. And
An arm plate locking portion in which a part of the metal plate forming the top plate is bent toward the lower surface side is provided at a position near both ends of the top plate of the fixing bracket in the length direction, and the back surface of the top plate is provided. In a flooring fixture in which the support legs are fixed to the lower surface of the fixing bracket by locking both ends of the arm plate stacked on the arm plate to the arm plate locking portion.
Each arm plate locking portion provided on the top plate of the fixing bracket has a pair of punched holes provided at a distance in the length direction of the top plate, and a band-shaped portion between the punched holes, the upper surface of which is the top plate. It is formed by a receiving plate portion that is bent so as to be located below the lower surface by the amount corresponding to the thickness of the arm plate, and the arm plate is inserted and locked between the lower surface of the top plate and the upper surface of the receiving plate portion. It is something like that.

Here, both ends of the fixing bracket are formed at the separated ends by making the top plate and the pressing portion equal in length, and the total length of the fixing bracket is the length required for the pressing portion to press and fix the flooring material. The top plate has a long rectangular shape along the length direction of the flooring material, and small holes are provided on both sides in the length direction sandwiching the screw insertion hole in the center thereof.

The arm plate of the support leg has a strip shape that is slightly shorter than the total length of the fixing bracket, and a protrusion that fits into the small hole when it is overlapped on the back surface of the top plate of the fixing bracket at positions on both sides of the screw insertion hole. Is provided so that the arm plate can be positioned and fixed to the top plate in the length direction and the width direction, and the pedestal of the support leg has a screw hole penetrating along the vertical axis. It has a square tubular shape, and the dimension from the lower surface to the lower end of the arm plate is set shorter than the height from the lower surface of the concave groove of the floor material to the base material. The elastic legs of the above are provided so as to project downward, and the fixture temporarily placed on the base material is made to stand on its own so as not to fall over by the elastic legs.

According to the present invention, the floor material fixture comprises a fixing bracket formed by a top plate and pressing portions provided on both sides thereof, and a resin support leg to be mounted on the back surface of the top plate. By providing support leg locking portions on the top plate of the fixing bracket near both ends and locking both ends of the arm plate overlapped on the back surface of the top plate to the supporting leg locking portions, the fixing bracket can be attached. Since the support legs are fixed to the lower surface, it is possible to eliminate the occurrence of exposed portions due to the protrusion of the arm plate at both ends of the fixing bracket, and even if the support leg locking portion has a portion penetrating the top plate. Since this penetrating part can be set small and the arm plate is located on the back side of the top plate, the exposure of the arm plate to the outer surface of the top plate can be minimized, and a plurality of fixtures can be used. Even if an external impact or vibration is applied during transportation, the metal fixing brackets are less likely to collide with the arm plate of other fixtures, and the arm plate made of synthetic resin is scratched. It is possible to prevent the fixture from being attached or broken, and thus it is possible to prevent a decrease in the commercial value of the fixture and the occurrence of defective products during transportation and the like.

In addition, by making the top plate of the fixing bracket and the pressing portion the same length and separating both ends of the fixing bracket to serve as the ends, it is possible to prevent a decrease in strength at both ends of the pressing portions on both sides, and the floor at the pressing portions on both sides. The material fixing force can be improved.

Furthermore, since the support legs attached to the top plate of the fixing bracket allow the fixture temporarily placed on the base material to stand on its own so that it does not fall over, the metal provided at both ends of the fixing bracket by the conventional fixture. By omitting the legs made of steel, the seating part for the base material is made of synthetic resin material, so that the rust preventive layer of the steel base material is not damaged and rust is generated on the base material. Since it is not allowed to be used, it is possible to cope with the case of constructing a deck outdoors, and by omitting the legs in the conventional fixture, the amount of the material metal plate used for forming the fixing bracket can be reduced.

The followability of the lower edge of the pressing portion 5 to the lower surface of the pressing portion 5 may be improved.

The fixture 1 of the present invention has the above-described configuration, uses a flooring material a provided with concave grooves b on both sides in the length direction, and uses the flooring material a as a base material d for joists, large pulls, etc. On the other hand, when the deck is constructed by arranging them in parallel, the floor material a is used to fix the floor material d to the base material d.

As shown in FIGS. 1 to 3, the fixture 1 is assembled by superimposing and fixing the support legs 3 on the lower surface of the top plate 4 of the fixing bracket 2.

The assembly is performed by stacking the arm plates 10 of the support legs 3 on the lower surface of the top plate 4 of the fixing bracket 2 in the length direction, and providing both ends of the arm plates 10 at both ends of the top plate 4. The protrusions 14 on the upper surface may be fitted into the small holes 8 by locking each of the 9s, and the vertical holes 13 of the support legs 3 communicate with the screw insertion holes 7 of the top plate 4 to form a coaxial center shape.

As shown in FIG. 9, the fixture 1 is built by screwing a screw 6 from the screw insertion hole 7 of the top plate 4 into the vertical hole 13 of the support leg 3, and is built on the base material d that supports the floor material a. This fixture 1 is placed on the floor, one of the pressing portions 5 is inserted into the concave groove b of the floor material a which is fixed first, and the fixture 1 is attached to the base material d by the pair of elastic legs 12 and 12. Let it stand on its own and put it in a temporary position.

In such a temporarily placed state of the fixture 1, the screw 6 is screwed halfway toward the base material d to temporarily fix the fixture 1, and then a new floor material a is placed next to the floor material a. They are arranged in parallel and placed on the base material d, and the lower protrusion c of the new floor material a is inserted under the other pressing portion 5.

A new floor material a is arranged in parallel next to the floor material a, and the pedestals 11 of the fixture 1 to be temporarily fixed are sandwiched between the side surfaces of the floor materials a and a on both sides. When a tool is inserted through the joint gap between a and the screw 6 is screwed in, and the screw 6 pushes down the entire fixture 1 through the top plate 4 of the fixing bracket 2, the fixture 1 to which the pushing force is applied is an elastic leg 12. , 12 lowers the top plate 4, and as shown in FIG. 10, both pressing portions 5 and 5 push down the lower protrusions c and c of both floor materials a and a to form both floor materials a. The a is finally fixed to the base material d. At this time, the elastic legs 12 and 12 are crushed and fit in the space between the floor material a and the pedestal 11, or escape to the adjacent space.

By this main fixing, the floor material a and the fixture 1 are coupled and fixed, so that both the floor materials a and a pushed by the pressing portions 5 and 5 are fixed so as not to move in the length direction and the width direction. Therefore, it is possible to reliably prevent the occurrence of vertical displacement and lateral displacement of the floor material a.

A deck can be constructed by fixing the floor material a with the fixture 1 as described above at each base material d and arranging the floor materials a in parallel in this way.

In order to replace the damaged fixture 1 with a new one in the deck after construction, insert a tool through the gap between both flooring materials a and a in parallel, loosen the screw 6, and use the fixing bracket 2 as the base material. The fixing to d and the floor materials a and a is released, the fixture 1 is moved in the length direction of the gap between the floor materials a and a by a tool, and the fixture 1 is taken out from the end of the gap.

Contrary to the work of taking out the fixture 1 described above, a new fixture 1 is inserted from the end of the gap, and the new fixture 1 is moved by a tool in the length direction of the gap between the floor materials a and a. By screwing the screw 6 onto the base material d, the floor materials a and a can be fixed.

By utilizing such a replacement work of the fixture 1, the damaged floor material a can be partially replaced, and the fixture 1 is removed on both sides of the floor material a to be replaced. A new floor material a may be placed in the portion from which the floor material a has been removed, and the fixture 1 inserted from the gap end between the floor material a and a may be screwed into and fixed to the base material d.

As described above, in the fixture 1 of the present invention, the arm plate locking portions 9 are provided at positions near both ends of the top plate 4 of the fixing bracket 2, and both ends of the arm plate 10 are used as the arm plate locking portions 9. Since the support legs 3 are fixed to the fixing metal fittings 2 by locking each of them, it is possible to omit the conventional coupling of the legs to both ends of the top plate 4, and the top plate 4 and both pressing portions 5 are equal. Both ends of the fixing bracket 2 can be made long to have a structure of separated ends having excellent strength, so that when the floor material a is pressed, both ends of both pressing portions 5 do not spread. Since strong fixing strength of the floor material can be secured and the punched holes 16 and 18 of the arm plate locking portion 9 are closed on all sides, the exposed portion of the arm plate 10 on the upper surface side of the top plate 4. When a plurality of fixtures 1 are packaged at the same time, it is possible to reduce the occurrence of a situation in which another fixing bracket 4 scratches or breaks the end portion of the arm plate 10 due to an external impact. become.

Further, since the contact of the base material d with the upper surface is only the elastic legs 12 of the support legs 3 made of synthetic resin, even if the base material d is made of steel and has been rust-proofed, it is supported by tightening the screws 6. Even if the elastic leg 12 of the leg 3 is crushed and presses or slides on the upper surface of the base material d, it will not be damaged. Therefore, the fixture 1 of the present invention can be used for outdoor deck construction. Become.
