Field of the Invention The present invention relates to a structure for connecting a vertical edge of a fence and a vertical edge of a fence in which hollow vertical rails are vertically installed at predetermined intervals between vertical edges of pillars extending in parallel. It is a thing.

[0002]

2. Description of the Related Art A conventional fence is constructed by vertically arranging furring strips vertically between pillars standing at a certain distance. The peripheral edges of both ends were welded and joined to the furring strip. Therefore, welding work requires a lot of time and labor, and there is a problem that workability is poor.

Further, there is a problem that a welding mark is left on the surface in the vicinity of the welded portion due to the welding, it is difficult to apply coating or plating in the vicinity of the welded portion, and the appearance of the entire fence is significantly impaired.

[0004]

From the above points, the present invention is
It is an object of the present invention to provide a joint structure of a fence brim and a vertical rail, which has good workability, does not impair aesthetics, and is also firmly joined.

[0005]

In order to solve the above-mentioned problems, the structure for connecting the furring strip and the vertical rail of the fence of the present invention according to claim 1 is
In a fence in which vertical bars are attached at a predetermined interval in the longitudinal direction between the upper and lower furring strips, a tubular furring strip having a slit-shaped opening in the longitudinal direction is arranged in parallel vertically with the openings facing each other. The fitting recesses are provided at opposite ends of the opening at predetermined intervals in the longitudinal direction, and the protrusions are provided at substantially the center of the fitting recess.
The outer surface near the end of a hollow vertical bar whose both ends are tapered is fitted into the fitting recess, and the protrusion is inserted into a hole provided at a position facing the side surface of the vertical bar. It is characterized by that.

With this structure, the outer surfaces near both ends of the vertical bar fit into the fitting recesses of the furring strip, and the projections of the fitting recesses are provided at the positions facing the side surfaces of the vertical bars. The vertical rail is firmly connected between the upper and lower furring strips because it is inserted into the hole. Further, since both ends of the vertical rail are formed to be tapered, it becomes easy to press and fit the furring strip into the fitting recess. Further, even if the vertical bar is a circular pipe, since the protrusion is inserted into the hole, the vertical bar is prevented from rotating in the circumferential direction.

[0007] Next, the connecting structure of the furring strip and the vertical rail of the fence of the present invention according to claim 2 is a slit-shaped fence in which the vertical rail is mounted at a predetermined interval in the longitudinal direction between the upper and lower furring edges. Cylindrical furring strips having an opening in the longitudinal direction are arranged in parallel vertically with the openings facing each other, and the fitting recesses face each other on both side edges of the opening at predetermined intervals in the longitudinal direction. The projection is provided in the center of the fitting recess so as to face each other, and the outer surface near the end of the hollow vertical bar whose both ends are tapered is fitted to the fitting recess. At the same time, the projection is fitted in a recess provided at a position opposite to the side surface of the vertical rail.

With this structure, the outer surfaces near both ends of the vertical bar fit into the fitting recesses of the furring strip, and the projections of the fitting recesses are provided at the positions facing the side surfaces of the vertical bars. Since it is fitted in the concave portion, the vertical rail is firmly connected between the upper and lower furring strips. The fact that both ends of the vertical rail are tapered has the same effect as in claim 1. Further, even if the vertical bar is a circular pipe, the protrusion is fitted into the recess, so that the vertical bar is prevented from rotating in the circumferential direction.

The fitting recess 8 is formed in a shape corresponding to the outer peripheral shape of a hollow vertical bar 9 which will be described later, and if the vertical bar 9 has a rectangular cross section, a rectangular shape (so that one side near the end can be fitted). 2 and 3) and if the vertical rail 9 has a circular cross section, it is formed in a substantially semicircular shape (FIG. 5) so that substantially one side near the end can be fitted.

The size and shape of the protrusion 10 are not limited as long as they do not protrude beyond the front surface of the edge 3. In the drawing, both sides of the tip of the small-piece-shaped quadrangular protrusion 10 are cut off to form a narrow width at the tip.

Next, the vertical rail 9 vertically attached between the upper and lower furring strips 1 has a hollow pipe shape, and its cross-sectional shape corresponds to the fitting concave portion 8 of the furring strip 1 and is rectangular or circular. To be done. Holes 11 having a shape of an isosceles triangle, an equilateral triangle or the like into which the projections 10 of the furring strip 1 are fitted are formed near both ends of the vertical rail 9 by notching at side facing positions.
An end portion side closer than the hole 11 is pressed inwardly to form a tapered tapered surface 12. The hole 11 has one apex facing toward the end. It should be noted that the hole 11 may have any shape as long as the protrusion 10 is fitted therein, and is not limited to such shape.

Next, FIGS. 6 and 7 are cross-sectional plan views showing an embodiment of the connecting structure of the present invention according to claim 2, wherein the recess 13 is replaced by the vertical bar 9 instead of the hole 11 of claim 1. 6A and 6B are provided at opposite positions on the side surfaces near both end portions of FIG. 6, FIG. 6 shows a case where the vertical bar 9 has a rectangular cross section, and FIG. 7 shows a case where the vertical bar 9 has a circular cross section. In this case, the protrusion 10 that fits into the recess 13
It is desirable to form a protrusion having a pointed tip, which is smaller than the protrusion 10 inserted into the hole 11.

In the method of connecting the furring strip 1 and the vertical rails 9 having such a configuration, a plurality of vertical rails 9 are horizontally arranged on a stand at predetermined intervals and both vertical rails 9 are fixed so that both vertical rails 9 do not move. The vicinity is held on a table by a jig, the opening 2 of the furring strip 1 is directed toward the end side of the vertical crosspiece 9, and the furring strip 1 is horizontally moved from both end sides of the vertical crossbar 9,
When the furring strip 1 is inserted along the taper surface 12 formed to be tapered, the opening 2 of the furring strip 1 is expanded by elasticity.
