Description

[Detailed description of the invention] (Industrial field of application) This invention relates to an improvement of the structure for attaching the vertical beams of a lattice-type fence.

(Prior art) Conventionally, in the case of protective shelves for pedestrians/bicycles, intrusion prevention shelves, etc., a plurality of vertical bars 2 are installed in a grid pattern between upper and lower horizontal bars 1, as shown in Fig. 4. A lattice type fence is often used.

When assembling such a lattice-type fence, a standard panel P is manufactured in advance by attaching both ends of a plurality of vertical bars 2 between the upper and lower horizontal bars 1 by welding or latching metal fittings at a factory, and In this process, the surface-treated panel P is joined to the support column 4 using metal fittings, bolts, or the like.

(Problem to be solved by the invention) However, in conventional lattice-type fences, standard panels P were manufactured using welding and hanging metal fittings, which resulted in complicated manufacturing operations and reduced panel manufacturing costs. It was expensive, and it was difficult to add variety to the fence design.

On the other hand, if panels of various designs are constructed by welding or using metal fittings depending on the construction site, a problem arises in that the manufacturing work at the factory or on-site becomes extremely complicated.

In view of these problems, the object of this invention is to provide a lattice-type fence that can reduce the manufacturing cost of panels and also allows for easy diversification of designs.

(Means for Solving the Problems) As a result of intensive research to solve the above-mentioned problems, the inventor of the present invention has found that in the above-mentioned lattice-type fence, even if the pillars and the rim are the same, the entire panel design It is possible to add diversity to the design of the bar, and the horizontal and vertical bars are made of hollow material, and the ends of the vertical bars are fixed to the bar member by compressive deformation to prevent them from coming off.
The present invention was developed based on the fact that if the bar member is inserted into the horizontal beam, the horizontal beam and the vertical beam can be easily assembled at the construction site.

In other words, the structure for attaching vertical bars of a lattice-type fence according to the present invention is as follows: ``In a lattice-type fence in which a plurality of vertical bars are attached in a lattice shape between upper and lower horizontal bars, the horizontal bars are provided with hollow elongated members, Hollow material is used for the vertical bars, and long grooves are formed in the horizontal bars in the longitudinal direction.The end of the vertical bars is inserted into the long grooves toward the inside of the horizontal bars, while a bar of a predetermined length is inserted inside the horizontal bars. A member is inserted, a plurality of holes are formed in the bar member at predetermined intervals in the longitudinal direction, and the ends of the vertical beam are fitted into each of the plurality of holes, and both side parts sandwiching the bar member at the end are inserted. Alternatively, one side of the bar is compressed and flattened so that the end of the vertical bar is fixed to the bar member without coming off.

Here, the bar member may have any shape as long as it does not fall from the long groove when inserted into the horizontal rail, and for example, a flat bar may be used.

(Function) When assembling a fence panel, first insert the end of the vertical bar into each hole of the bar member, compress and flatten both sides or one side of the bar member at the end, and then attach the end of the vertical bar to the bar member. What is necessary is to fix the bar member in a way that prevents it from coming off, and insert the bar member into the horizontal bar while inserting the end portion of the vertical bar into the long groove.

In this way, with this invention, fence panels can be manufactured more easily than when conventional welding or hooking hardware is used, and the vertical and horizontal beams can be changed as appropriate depending on the construction site. As a result, fence panels of a wide variety of designs can be easily assembled on-site without complicating manufacturing operations in factories or on-site.

(Example) Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings. Fig. 1 is a side view showing the structure for attaching the vertical bars of a lattice-type fence according to an embodiment of the present invention, Fig. 2 is a view taken along the - line, and Fig. 3 is an explanatory diagram of the fixing structure of the bar member and the vertical bars. It is.

In the figure, a lattice-type fence is constructed by attaching a plurality of vertical bars 2 between upper and lower horizontal bars 1 in a lattice shape. Hollow material is used.

Further, a long groove 11 is formed in the horizontal bar 1 in the longitudinal direction, and an end portion of the vertical bar 2 is inserted into the long groove 11 toward the inside of the horizontal bar 1.

Further, a bar member 3 of a predetermined length made of a flat bar is inserted into the hollow portion 12 of the horizontal beam 1,
The bar member 3 is set to a width that does not fall out from the long groove 11, and a plurality of holes 31 are bored in the bar member 3 at predetermined intervals in the longitudinal direction, and each of the plurality of holes 31 has a plurality of holes. The end portion 21 of each vertical bar 2 is inserted, and both side portions of the end portion 21 sandwiching the bar member 3 are flattened by mechanical compression molding, whereby the end portion 21 of the vertical bar 2 is It is fixed to the bar member 3 so as not to come off.

Next, the effects will be explained.

When assembling the lattice-type fence of this structure, first, a steel strip is formed into a tube, and both joined edges of the steel strip are bent inward to produce the horizontal beams 1. At this time, the gap between the inwardly bent edges becomes a long groove 11 extending in the longitudinal direction.

On the other hand, the bar member 3 is a flat bar of a predetermined length that can be inserted into the hollow portion 12 of the horizontal crosspiece 1 from the lateral direction and that does not fall out of the long groove 11. multiple holes 3
1.

The end portions 21 of the hollow vertical beams 2 are fitted into each hole 31 of the bar member 3, and both side portions of the end portions 21 sandwiching the bar member 3 are continuously compressed and flattened using a mechanical compression molding method. The end portion 21 of each vertical beam 2 is fixed to the bar member 3 so as not to come off.

When the vertical bar 2 and the bar member 3 are connected in this way, the bar member 3 is inserted into the hollow part 12 of the horizontal bar 1 while inserting the end portion 21 of the vertical bar 2 into the long groove 11 of the horizontal bar 1 from the horizontal direction. A lattice-type fence can be assembled by inserting the panel P and attaching it to the existing supports (see 4 in FIG. 4).

In the vertical bar mounting structure of the lattice type fence of this embodiment as described above, the end portion 21 of the vertical bar 2 is fitted into the hole 31 of the bar member 3, compressed and flattened, and fixed to the bar member 3 so that it does not come off. Since this is inserted into the horizontal crosspiece 1 from the side, the fence panel can be manufactured easily, and since conventional welding is not used, there is no welding distortion and welding marks appear on the surface. Therefore, the appearance is good, no special post-processing is required, and the panel cost can be reduced.

In addition, in the vertical frame mounting structure of the lattice type fence of this embodiment, the vertical frame 2 is attached to the bar member 3, and this is inserted into the hollow part 12 of the horizontal frame 1 to manufacture the panel. Fences with a wide variety of designs can be easily assembled on-site without complicating on-site manufacturing operations.

(Effect of the invention) As described above, according to the invention, in a lattice-type fence in which a plurality of vertical bars are installed in a lattice pattern between the upper and lower horizontal bars, the horizontal bars made of hollow long materials are attached in the longitudinal direction. A long groove is formed in the bar member, and the end of the vertical bar is inserted into each of the plurality of holes of the bar member, and both sides or one side of the bar member at the end are compressed and flattened, and the end of the vertical bar is inserted into the bar member. By fixing the bar to prevent it from coming off, and inserting the end of the vertical bar into the long groove of the horizontal bar and inserting the bar inside the horizontal bar, it is possible to use a wide variety of products without complicating the manufacturing work in the factory or on-site. This has the effect of making it possible to easily and inexpensively produce a designed fence.
