Abstract

This design is to secure the safety railing to the wall by fixing the safety railing to the wall. By changing the direction of the load applied at the portion where the vertical load occurs, the stress of the shear load is dispersed. The upper end fixing piece is prevented from being pulled out due to the stress concentration due to the vertical load,
A safety guardrail fastening member composed of a wall surface fixing member fixedly installed on the wall surface of the balcony, and a safety guardrail fastening member having one side fitted to the wall surface fixing member and the other side fitted to the railbar of the safety guardrail.

Description

Safety railing fasteners

The present invention relates to a safety rail fastener for installing safety nails on a wall of a railing, and more particularly, to a rail railing fastener provided on a wall surface of a railing with a nail or a piece to distribute a vertical load and a shear load, And a safety rail fastener configured to prevent damage due to concentration.

Generally, safety railing is installed on the railing of high-rise buildings to prevent falls.

Such a handrail is provided with a separate safety barrier fastener for fixing the safety barrier on the wall surface, and a safety barrier is fixed to the wall surface through the fastener.

Such a conventional safety rail fastener is formed with holes formed in the upper and lower sides and protruding from the central one surface so that the horizontal bar of the safety railing can be fitted and engaged.

However, since the conventional safety rail fastener is formed with a fastening hole around the fastening rod, the fastening nails which are out of the wall surface are easily pulled out through the fastening hole by the vertical load generated in the fastening rod, The load is concentrated and is easily broken.

Application No. 10-2007-0059476

In this design, when the safety railing fastener is fixed to the wall, it is possible to distribute the stress of the shear load by changing the direction of the load applied at the portion where the vertical load is generated. And it is an object of the present invention to prevent breakage due to stress concentration due to a load.

In order to accomplish the object of the present invention, the safety railing fastener secured to the wall of the railing is composed of a wall fixing member and a safety railing fixing member. The wall fixing member includes a wall fixing plate, And a fastening hole formed at an upper portion of the wall fixing plate to provide a safety barrier fastener formed on the load converting surface. do.

The present invention is based on the idea that by installing the safety railing, the vertical and shear loads generated by the combination of the safety rails with the nails or pieces fixed to the wall fixed to the wall by nails or pieces or the like are dispersed in the wall, The safety of the safety railing can be improved by preventing breakage of the fixing plate.

Fig. 1 is a perspective view of the present invention
2 is a cross-sectional view
Fig. 3 is a perspective view showing a state in which a safety guardrail is coupled to the present invention; Fig.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are cross-sectional views showing a construction of the present invention and a state in which it is installed on a handrail. In this embodiment, the safety railing 10, which is formed by joining a plurality of handrail pieces, A safety barrier fastener is disclosed.

The safety barrier fastener comprises a wall surface fixing member (20) and a safety guard fixing member (30).

The wall surface fixing member 20 is formed of a fastening plate 21 having a predetermined length and a fastening pipe 23 projecting to one side of the fastening plate 21.

The fastening plate 21 is formed with fastening holes 21a and 22a through the upper and lower surfaces thereof so as to be fixedly mounted on the wall surface with a nail or a piece of material. In order to reduce the tensile load, shear load, (22a) formed on the load-converting surface (22).

The load-converting surface 22 is formed with an inclined surface at a predetermined angle with respect to a vertically installed fastening plate 21, and a lower portion is protruded, and a fastening hole 22a is formed in the inclined surface.

The fastening pipe 23 is protruded at a position eccentric from the center of the fastening plate 21 at a predetermined interval downward.

The safety railing fixing member 30 includes a length adjusting pipe 31 having a diameter to which a fastening pipe 23 is inserted and a fixing ring 32 having a safety railing bar at one end of the length adjusting pipe 31 .

In the present invention constructed as described above, the wall fixing member 20 is fixed to both side walls of the balcony using nails or pieces, and the both ends of the railing bar constituting the safety railing 10 are fixed to the fixing The safety railing is installed by inserting the length adjusting pipe 31 into the fastening pipe 23 of the safety railing fixing member 30 after inserting it into the ring 32.

At this time, the depth of insertion of the fastening pipe (23) into the length adjusting pipe (31) can be adjusted to adjust the proper distance between the safety railing and the balcony, and the safety railing can be installed vertically.

Meanwhile, when the wall surface fixing member 20 is fixed by a nail or the like through the fastening hole 22a of the load conversion surface 22 protruding from the upper surface of the fastening plate 21 installed on the wall surface of the balcony, The nails and the like are obliquely inclined obliquely without being struck perpendicular to the wall surface so that the vertical load generated after the safety guardrail 10 is engaged and the shear load generated by the vertical load are absorbed by the wall surface through the nail The effect of load distribution is obtained.

The fastening pipe 23 is eccentrically formed at a predetermined distance downward from the center of the fastening plate 21 so that the gap between the fastening pipe 21 and the fastening hole 21a formed at the lower end is relatively short, A larger supporting force is generated in the nail inserted into the diagonal line with respect to the wall surface so that the damper of the fastening plate 21 and the load bearing surface 22 are embedded The nails are not drawn.
