Description

Welded balustrade

The present invention relates to a non-welded balustrade, and more particularly, to provide a balustrade that can couple a connecting member to a support member of a balustrade structure such as a veranda, a road, a staircase, a fence, and a roof without welding.

Since more than 90% of the railings currently in use are welded by using stainless steel round pipes, they are not only restricted by the shape of the railings, but also increase the assembly cost.

In other words, since the joint is treated by welding, it is necessary to smooth the end loss of the weld after welding, which increases the manufacturing time of the railing structure.

Therefore, in order to solve such a problem, a separate connector is fixed to the support member by welding, and then the methods of joining the members of the handrail structure by the fastening means or the fastening means are connected to the connection member. There was a problem that the assembly member is not firmly assembled due to the relaxation or bending occurs in the connection of the members.

The present invention is to solve this problem,

The purpose of the present invention is that the welder, who is a skilled worker, can mass-produce with simple manpower without welding, and the material cost can be reduced by using iron, and the strength is better than that of welding, and the beauty of the combined place It is to provide a welding-free balustrade for excellent powder coating.

Another object is to provide a pipe using a plastic change coupling portion and an elastic coupling portion to simplify the parts to be assembled, respectively.

The object of the present invention is configured to be coupled to the upper, middle, lower square pipe through the plastic change coupling portion, and in the handrail assembled by using the suspended square pipe and the lean round pipe, the upper, middle, lower Ganche circular pipe coupled to the square pipe and the lower square pipe can be configured to be fastened through the elastic coupling portion.

The elastic coupling portion of the lean round pipe may form a bent portion on both sides of the circular pipe, and may form a tapered surface in which the front side of the bent portion is inclined.

In addition, the plastic change coupling portion formed in the upper, middle, and lower square pipes is formed by forming a plurality of protrusions in the outer outer diameter portion of the insertion hole.

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

FIG. 1 is a schematic view showing an embodiment of a state of use of a welding-free balustrade according to the present invention, and shows a handrail assembled without welding.

The upper square pipe (1) fixed to the upper left and right walls can be used to increase the fixed strength of the wall using a larger dimension of the other pipe. The top and one side of the upper square pipe (1) is fixed, the iron columnar pipe 4 is fixed to the other side and the ground makes it possible to firmly support the left and right of the handrail.

Between the upper square pipe 1 formed of the skeleton and the steel column circular pipe 4, the middle square pipe 2 and the lower square pipe 3 forming the skeleton of the handrail are sequentially assembled. At this time, the coupling portion of the iron pillar circular pipe (4) formed of a cross between the middle square pipe (2) and the lower square pipe (3) is formed so that the plastic change coupling portion (A) is tightly bound.

And the plurality of liver-shaped circular pipes 5 coupled between the middle square pipe 2 and the lower square pipe 3 is configured to be fastened through the elastic coupling portion (B) formed in the upper and lower ends.

The plastic change coupling portion (A) and the elastic coupling portion (B) will be described later.

FIG. 2 is a perspective view and a cross-sectional view showing the respective components used in the non-welded handrail, FIG. 2A shows the upper square pipe 1, and FIG. 2B shows the cross-sectional view of the light circular pipe 5.

The middle square pipe (2) and the lower square pipe (3) of the middle, lower crossbars adopt the same configuration as the upper square pipe (1) of FIG. 2a, and only the upper square pipe (1) is more than other square pipes. The one with the large dimension of thickness is used.

In addition, the thickness of the middle square pipe (2) and the lower square pipe (3) is thicker than the thickness of the lean round pipe (5) of Figure 2b to be more easily and firmly fixed when fastening.

A plurality of insertion holes 11 are drilled and installed in the upper square pipe 1 of FIG. 2a, and the middle square pipe 2 and the lower square pipe 3 are also drilled and installed in the plurality of insertion holes 11 in the same structure. It is.

The simple round pipe 5 of FIG. 2b is inserted and fixed in the insertion hole 11 of the middle square pipe 2 and the lower square pipe 3.

The curved circular pipe 5 of FIG. 2B has both bent portions 7 formed thereon and is machined to form a taper 8 at the front end of the bent portion.

3 is a cross-sectional view of the jig and the plastic change coupled state for explaining the plastic change coupling portion used in the embodiment of the present invention.

That is, the joining portion of the iron pillar circular pipe 4 formed by the lower square pipe 3 and the cross is formed by the plastic change coupling portion A to be closely bound, and thus the insertion hole of the iron pillar circular pipe 4 A plurality of projections 13 are forcibly fitted and fixed in 12).

Here, the plurality of protrusions 13 formed on the steel pillar round pipe 4 are pressed by making both molds 21 smaller than the outer diameter of the steel pillar round pipe 4 by the material thickness D using a plastic mold for plastic change. When the protrusion is applied, a protrusion 13 having a thickness D is formed.

4 is a cross-sectional view showing a side view of the square pipe used in the present invention and a rubber stopper coupled thereto. After the assembly is completed, the inlet that protrudes to the outside can be fitted with a rubber stopper 5 to prevent rainwater from seeping and at the same time, the appearance can be beautiful.

In particular, the Gansu round pipe (5) by using a round steel pipe to improve the beauty of the balance and do not weld to the assembly can obtain a clean bonding surface, each component is an elastic coupling portion (B) and plastic change coupling portion (A) Because it is an assembly by elastic force and plastic deformation by), the bonding strength is better than welding, and the assembly surface is clean, so that corrosion can be prevented as much as possible when powder coating, and beautiful colors can be beautiful by using various colors.

In addition, the tapered surface of the liver-shaped circular pipe 5 is processed to be 0.3 cm or more smaller than the insertion hole 11 to facilitate assembly in a tapered shape, and the distance to the bent portion 7 is greater than that of the suspended square pipe 2 assembled therein. The thickness is processed by 1.5 times smaller, and as shown in FIG. 5, the joint does not move after joining, and the gland round pipe 5 is inserted into and fixed in the suspended square pipe 2 so that the weld strength is increased by the elastic coupling part B. Excellent characteristics.

In addition, the plastic change coupling portion (A) is coupled as shown in Figure 3 can be combined so as not to move up and down by plastic deformation of the column of the combined binder, this is also the desired color for powder coating because there is no node by welding Can be expressed beautifully.

As described above, the present invention is a handrail that is manufactured without welding by using square and round pipes and uses the principle of elastic deformation and plastic deformation, and can obtain higher strength than welding handrail. Due to the high cost of the conventional disadvantages can be solved.

In particular, the present invention is combined with no welding, there is no welding node has the effect of beautifully expressing the color when powder coating from the outside.
