The present invention relates to a railing, and more particularly to a coupling structure of the railing that can enhance the coupling force between the strut constituting the railing and the frame connected to the strut and the pattern plate is connected.

Generally, railings are installed on the edge of a road or on one side of a building to restrict people's traffic.

This conventional railing is composed of a strut installed at a predetermined interval and a frame connected to the strut and coupled with a pattern plate therein. Usually, the strut and the frame are simply joined by welding or welding using bolts and nuts. .

However, the conventional railing coupling structure as described above has a problem in that the frame to which the railing and the pattern plate are connected is easily separated from an external impact.

The present invention has been made in order to solve the problems of the prior art, a plurality of pillars are installed on the ground at a predetermined interval and the pattern plate is connected to the inner side and strengthen the coupling force between the frame coupled to the pillar to improve the circular impact The aim is to provide a sustainable structure of handrails.

The coupling structure of the handrail according to the present invention for solving the above problems is provided with a plurality of pillars which are formed on both sides of the through-hole communicating with each other and installed upright at a predetermined interval on the flat surface, and installed between the pillars and the through-hole In the coupling structure of the handrail formed of a fastening hole is formed to communicate with the pattern plate is connected to the inside, and the fastening means for connecting the support and the frame through the through hole and the fastening hole, the fastening hole is formed in the middle The first fastening hole adjacent to the support by the jaw portion, and the second fastening hole facing the first fastening hole on the basis of the stepped portion, the fastening means is installed across the through hole and the locking step is formed on one side An inner nut which is caught by the through hole, a first spiral part is formed on an inner circumferential surface, and a second spiral part is formed on the other outer circumferential surface; Fastening bolts respectively inserted in the second fastening holes and coupled to the first helix of the inner nut; And a female nut disposed in the first fastening hole and fastened to the second spiral part.

Hereinafter, with reference to the accompanying drawings an embodiment of the coupling structure of the handrail according to the present invention will be described in detail.

1 is a perspective view showing an embodiment in which the handrail coupling structure according to the present invention is applied linearly to a flat surface, FIG. 2 is an exploded perspective view of the handrail coupling structure shown in FIG. 1, and FIG. 3 is a handrail shown in FIG. 1. A plan cross section of the coupling structure.

The coupling structure of the balustrade according to the present invention includes a support 10 and a frame 20 coupled to the support 10 and having a pattern plate installed therein, or itself serving as a pattern plate, and the support 10. And by a combination of fastening means 30 for fastening the frame 20.

The strut 10 is a hollow member having an empty space therein. As shown in FIGS. 1 to 3, through holes 12 communicating with each other on both left and right sides are formed at an upper side and a lower side, and are defined on a flat surface. Plural pieces are installed upright at intervals.

The frame 20 is a rectangular frame that is formed inside the empty space and is installed between the support 10, the pattern plate for improving the aesthetics in the inner empty space by various fastening methods using bolts, nuts or welding, etc. It is connected.

The frame 20 has a fastening hole 22 is formed to communicate with the through hole 12 of the support 10, the fastening hole 22 is formed with a stepped portion 24 in the middle, the stepped portion The fastening hole 22 is positioned at the position opposite to the first fastening hole 22a on the basis of the first fastening hole 22a adjacent to the support 10 and the stepped portion 24. 10, it is divided into a second fastening hole 22b located far away.

The fastening means 30 is a means for firmly connecting the support 10 and the frame 20 through the through hole 12 of the support 10 and the fastening hole 22 of the frame 20. The configuration is composed of the inner nut 31 and the fastening bolt 32 and the female nut 33.

The inner nut 31 has a round locking jaw 31a formed at one end of the outer circumferential surface, a first spiral portion 31b is formed at the inner circumferential surface, and a second spiral portion 31c is formed at the outer circumferential surface of the other end.

The inner nut 31 has a diameter larger than that of the through hole 12 of the strut 10, and the entire length of the inner nut 31 is the left and right lengths of the strut 10. Is made longer. Therefore, when the inner 31 is installed across the through holes 12 formed on both sides of the support 10, the inner 31 is caught at the inlet of the through hole 12 into which the int 31 is inserted. The jaw 31a is caught, and the second spiral portion 31c protrudes from the opposite through hole 12.

It is preferable that the fastening bolt 32 makes an angled groove inside the bolt head rather than making an angle on the outer circumferential surface of the bolt head like a normal bolt. That is, it is preferable to configure the fastening bolt 32 to be commonly referred to as a wrench bolt for convenience of work.

The fastening bolt 32 begins to be inserted through the second fastening hole 22b of the frame 20 and passes through the first fastening hole 22a to form a first spiral part (n) formed on the inner circumferential surface of the inert 31. 31b). At this time, the bolt head of the fastening bolt 32 is caught by the stepped portion 24 and is no longer inserted.

The female nut 33 is disposed in the first fastening hole 22a of the frame 20. At this time, all of the first fastening holes 22a respectively formed in the frame 20 disposed on both sides of the support 10 are provided. The female nut 33 is not disposed at the upper end of the arm nut 33, and is disposed only at the first fastening hole 22a of the frame 20 provided on the right side of the support 10 as shown in FIGS. 2 and 3.

The female nut 33 disposed as described above is coupled to the second spiral portion 31c formed on the outer peripheral surface of the other end of the inner nut 31.

Therefore, the inner nut 31 is locked to the through hole 12 of the support 10 by the locking jaw 31a and the female nut 33, so that the inner nut 31 is not detached to either the left or right side of the support 10. .

In the above, as illustrated in FIGS. 1 to 3, the structure of the handrail coupling structure according to the present invention has been described only in a structure in which the frames are arranged in a straight line on both sides of the strut. It is also possible.

Figure 4 is a cross-sectional view showing an embodiment in which the railing coupling structure according to the present invention is applied to the flat surface in a curved manner, (A) is a view showing a state in which the two frames are vertically connected around the support, (B ) Is a view showing the two frames connected to form a predetermined angle around the support.

Even if the railing coupling structure is configured as shown in FIG. 4, the basic components constituting the coupling and the installation method thereof are not significantly different from those shown in FIGS. 1 to 3.

However, only the difference that the through hole 12 formed on one side and the other side of the support 10 is formed to have a predetermined angle or the inner nut 31 is bent to form a predetermined angle according to the angle formed by the through hole 12. There is only this. The construction and installation of the handrail coupling structure by such a degree of change can be fully implemented by those skilled in the art by the description based on FIGS. 1 to 3, and thus, the description of FIG. 4 will be omitted.

And, the handrail coupling structure according to the present invention may be configured as shown in FIG.
