Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an assembly and fixing structure for fences.

(Prior Art) For safety fences for sidewalks and boundary fences for land, fences having a structure in which posts are erected on the ground and face members are fixed to the posts with fixing metal fittings are often used.

In this kind of fence, Fig. 9 and 1
As shown in Figure 0, clamps CA are attached to the upper and lower ends of the strut 1 using stud bolts SB, and the clamps CA fix the rim F.
While the upper and lower frame lines W of the panel are fixed with studs S, a wire grip WG is attached to the vertical center of the column 1 with a stud bolt SB.
is attached, and the central frame line W of the face material is fixed by the wire grip WG.

(Problems to be solved by the invention) However, conventional fences have had the following problems due to their assembly and fixing structure.

Bolt heads and clamp heads protrude from the surface of the support, which not only impairs the appearance of the fence, but also poses a risk of injury in the case of guard fences for playgrounds and parks. It causes.

Since the rim is attached to the back or front of the column, the joint surface between the rim and the column must be flat, and the design of the front and back surfaces is different, which is not aesthetically pleasing.

Since it is bolted to the support,
Bolt holes are required, which creates cross-sectional defects in the struts and becomes a starting point for corrosion.

There are many parts such as stud bolts and clamps, which reduces work efficiency during assembly.

In view of this problem, the object of this invention is to provide a fence assembly and fixing structure that allows fences with the same design on both sides to be easily assembled with a small number of parts.

(Means for Solving the Problems) Therefore, in view of the fact that the above-mentioned problem lies in the fact that a bolt fastening structure is adopted for attaching the fence surface material to the pillars, the present invention has been developed to solve the problem. When assembling the fence by fixing the face material with fixing metal fittings, a dovetail groove extending vertically is formed on the side of the support, while the fixing metal fitting consists of a pair of plate-like members, and both plate-like members have a dovetail groove extending vertically. The tip head, the intermediate joint point, and the rear end leg are formed continuously in the longitudinal direction, and the tip head is formed into a curved shape corresponding to the cross-sectional shape of the dovetail groove, and the tip heads of both plate-like members are The intermediate contact parts are inserted into the dovetail grooves, and the intermediate contact parts are brought into contact with each other.The rear end legs are connected to each other by a connecting member with the face material in between, and by this connection, the tip head and the intermediate contact parts are connected to each other by a connecting member. The gist is that the fulcrum is expanded within the dovetail groove to prevent it from slipping out.

Here, the fixing fittings may be composed of plate-like members of the same shape, as shown in Fig. 1, or may be composed of plate-like members of mutually complementary shapes, as shown in Fig. 3. good. In short, the tip head is expanded around the intermediate joint by the pinching action of the rear end leg, and is fixed in the dovetail groove so as not to come out.

(Function) In the present invention, the tip head of the plate-shaped member is inserted into the dovetail groove on the side of the support, and the plate member is connected by sandwiching a face material between the rear end legs, and as the connection is made, the tip head becomes the intermediate contact point. The connecting members do not protrude from the surface or back surface of the support column because they are spread out from each other using the support points as fulcrums and are prevented from coming out of the dovetail groove.

Furthermore, since the face material is attached to the side surface of the support column, the joint surface of the support support and the face material does not need to be flat, and can be set to any shape.

Furthermore, since the dovetail groove on the side of the support and the head of the plate-like member fit together, there is no need to form bolt holes in the support, and compared to using stud bolts or clamps, etc. It has a small number of parts and is easy to assemble.

(Example) Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 6 show a structure for assembling and fixing a fence according to an embodiment of the present invention. In the figure, a pillar 1 is erected on the ground, and the pillar 1

Welmet science is used.

It is desirable that this well mesh suffix 2 is attached and fixed to the pillar 1 so that it has the same design when viewed from the front and rear sides, so that the middle part of the well mesh suffix 2 is fixed using the fixing metal fittings 3. It is assembled and fixed to the structure of this embodiment.

That is, as shown in FIGS. 1 to 4, the pillar 1 has dovetail grooves 11 extending vertically on both sides, and the dovetail grooves 11 have narrow entrances and are expanded to have a substantially circular cross section. ing.

On the other hand, the fixture 3 is composed of a pair of plate-like members. A tip head 31, an intermediate contact portion 33, and a rear end leg portion 32 are formed continuously in the longitudinal direction on this pair of plate-like members, and the tip head 31 has a shape corresponding to the cross-sectional shape of the dovetail groove 11. It is curved into a substantially arc shape.

The top heads 31 of both plate-like members are fitted into the dovetail groove 11, and their intermediate contact portions 33 are brought into contact with each other.

Further, the rear end leg portion 32 of the plate-shaped member is arranged so as to sandwich the vertical tension wire W1 on the side portion of the panel 2, and a bolt B is inserted into the bolt hole 34 of the rear end leg portion 32.
A nut N is screwed into this to connect both rear end legs 32 to each other, and the connecting action of the rear end legs 32 causes the distal end head 31 of the plate-like member to pivot around the intermediate contact portion 33. It is expanded within the dovetail groove 11 and pressed into contact with the inner surface of the dovetail groove 11, and thus the tip head 31 is fixed to the dovetail groove 11 so as not to come off, and the face member 2 is fixed to the support column 1 by the fixing metal fitting 3.

On the other hand, as shown in FIGS. 7 and 8, the upper and lower ends of the panel 2 are attached to the support 1 by means of fixing fittings 4.
are fixed at the upper and lower ends of the That is, the nut N is inserted into the dovetail groove 11 of the support 1, the bolt B is inserted into the bolt hole of the vertical part of the L-shaped member 41 of the fixing metal fitting 4, and the bolt B is inserted into the nut N in the dovetail groove 11. The fixing metal fitting 4 is attached to the support column 1 by being screwed together.

A clamp member 4 is attached to the horizontal part of the fixing fitting 4.
