Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure for attaching a rim to a support in a fence installed on the side of a road or the like.

[Conventional technology]

Conventionally, the frame mounting structure for fences has been constructed by connecting the band fitting for the support band and the band fitting for the trunk green with bolts or pins, and the band fitting for the support is fitted to the support and fixed by tightening with bolts. However, a structure is known in which the end of the rim is inserted into a band fitting for the rim and tightened and fixed with a bolt, and a structure in which the rim is brought into contact with a support and tightened and fixed with a U-bolt is also known. ing.

However, these rim mounting structures require the complicated work of tightening bolts when attaching the rim, take a long time to install, and furthermore, the rim mounting bolts are exposed to the outside. This resulted in problems such as poor appearance and the risk of bolts being lost during on-site construction.

[Purpose and structure of the invention]

The purpose of the present invention is to provide a structure for attaching the rim of a fence that can advantageously solve the above-mentioned problems. A pair of vertical support plates 2 are arranged at intervals in the vertical direction, and a locking protrusion 4 that projects in the vertical direction is provided at a position away from the support column 1 at one end of each support plate 2 in the vertical direction. The support plate 2 is provided with an incline in the vertically intermediate portion of each support plate 2 such that the amount of protrusion from the outer surface of the support plate 2 gradually increases as the locking protrusion 4 moves away from the locking protrusion 4 in the vertical direction. A locking protrusion 3 having a guide portion is bent to form a hollow body rim 5.
The slit 6 is press-fitted into the support plate 2 from above and below, and the inner edge of the slit 6 is arranged so as to engage with the locking end 7 of the locking protrusion 3. A body rim attachment structure for a fence, characterized in that an engaging protrusion 8 protruding into the body rim at an end is arranged so as to engage with a pillar side end of the locking protrusion 4. be.

When the locking fittings shown in FIGS. 16 to 18 are used as upper locking fittings, the cap 13 is fixed to the upper end of the partially cut-out cylindrical body 15C by welding, and the locking fittings shown in FIGS. When used as a locking metal fitting, it is used upside down.

19 to 21 show examples of the hollow flange 5 that can be used in the embodiment of the present invention. In the case of FIG. 19, a band-shaped metal plate such as a band-shaped steel plate is bent. , a body 17 of the body rim having a partially cut-out circular cross section and ribs 18 projecting into the body of the body 3 from both edges of the notch are formed, and the width of the slit 6 between the left and right ribs 18 is equal to the width of the body 17 of the body 17, which has a circular cross section. An engaging protrusion 8 that enlarges from the periphery toward the center of the rim and projects into the rim is integrally provided at the upper part of the end of the rim 5 by cutting and raising.

In the case of FIG. 20, the width of the slit 6 between the left and right ribs 18 is approximately uniform over the entire width of the ribs 18, but the other configurations are the same as in the case of FIG. 19.

In the case of Fig. 21, a band-shaped metal plate is bent and has a body 17 having a notch in the center of one side, and a body 17 that extends parallel to the inside of the body from both edges of the notch. A slit 6 is formed between the left and right ribs 18, and an engagement protrusion 8 as described above is integrally provided on the upper surface plate of the rim 5 by cutting and raising.

1 to 5 are the upper locking fitting 9 shown in FIGS. 6 to 9, the lower locking fitting 14 shown in FIGS. 10 to 12, and the rim 5 shown in FIG. 19.
A large number of supports 1 made of steel pipes with a circular cross section are arranged at predetermined intervals and embedded in a concrete foundation 19, and the upper locking fittings 9 are attached to the supports 1. The lower locking fitting 14 is fitted to the upper end, and the lower locking fitting 14 is fitted to the middle part of the support column 1. At the left and right ends of the fence wire mesh 20, there is a holding rod made of a band-shaped metal plate extending in the vertical direction. 21 is inserted, and the upper and lower ends of the holding rod 21 are arranged within the pair of support plates 2 in the upper locking metal fitting 9 and the lower locking metal fitting 14, and are secured by bolts 22 passing through them. , the upper locking metal fitting 9 and the lower locking metal fitting 14 are tightened and fixed to the column 1, and both ends of the holding rod 21 are connected to each of the locking metal fittings 9 and 14.

The upper rim 5 is press-fitted from above to the support plate 2 with a pair of locking protrusions 3 in the upper locking fitting 9, and the lower rim 5 is press-fitted into the support plate 2 with the pair of locking protrusions 3 in the upper locking fitting 9, and the lower fitting 5 is press-fitted into the support plate 2 with the pair of locking protrusions 3 in the upper locking fitting 9.
The support plate 2 with a pair of locking protrusions 3 is press-fitted from below. In this case, while the ribs 18 on both sides of the slit 6 in the furring 5 are guided by the inclined guide portions in the locking projection 3,
The rim 5 is deformed within its elastic limit so that the slit 6 of the rim 5 expands, and the moment the left and right ribs 18 pass the locking protrusion 3, the slit 6 is contracted by the elastic restoring force of the rim 5. Since the tips of the ribs 18 are arranged so as to contact or be close to the locking ends 7 of the locking protrusions 3, the furrow 5 is prevented from coming off in the vertical direction.

Furthermore, when the furring rim 5 is fitted to the support plate 2, the engaging protrusion 8 of the furring 5 is arranged so as to contact or be close to the support-side end of the locking protrusion 4 provided on the support plate 2. Therefore, the furrow 5 is prevented from coming off in the lateral direction.

A spiral coil-shaped support member 23 latched to both upper and lower ends of the fence wire mesh 20 is inserted into the furring 5, and both upper and lower ends of the wire mesh 20 are arranged in the slits 6 of the furring 5. .

When carrying out this invention, the locking protrusion 3 may be in the shape of a tongue piece cut and raised on the support plate or in any other arbitrary shape. Further, the furring attachment structure of the present invention may be implemented only for attachment to either the upper furring or the lower furring.

〔Effect of the invention〕

According to the present invention, the hollow flange 5 having the slit 6 and the engagement protrusion 8 is attached to the support plate 2 with the engagement protrusion 3 and the engagement protrusion 4 in the engagement fitting fixed to the support column 1. By simply pushing the fit together from above and below, the inner edge of the slit 6 in the rim 5 can be attached to the locking protrusion 3.
The furring edge 5 is arranged to engage the locking end 7 of the
The body rim 5 is moved in the lateral direction by arranging the engaging protrusion 8 of the body rim 5 to engage with the end of the locking protrusion 4 on the support plate 2 on the support plate side so as not to slip out in the vertical direction. It can be easily and quickly attached so as not to slip out, and therefore the above-mentioned problem in the conventional furring attachment structure can be solved.
