Description

Folding Type Safety Fence Enable to Control Length

The present invention allows the length of the safety fence used for road construction to be adjusted using a folding type, and supports the curved support on the horizontal side of the guide plate, and the support is supported by two legs so that it is not conducted by the wind. And a safety fence that is easy to install, dismantle and move.

Safety fences are installed to prevent the access of vehicles and people at various construction sites such as construction sites, manhole construction, and road construction. In general, two pillars are installed and plate blocking material is formed in the space between them. .

 Most of these safety fences are made of synthetic resins, which are installed in large sizes so that they do not fall down by the wind by filling them with sand or soil.These safety fences are placed in succession, and the safety fences are tied together to bind each other. In addition, the safety fence as described above is manufactured using a metal material. However, the conventional safety fence as described above is made of a synthetic resin or a metal material, and thus its weight is very heavy, which makes the movement and handling very inconvenient and mostly fixed. It is manufactured by integrating the shape, so if it is to be removed and stored, there is a problem that occupies the storage space very much. In addition, the wind or light shocks fall, and when dismantling the binding spheres to each other, there is a problem that must consume a lot of time and manpower for dismantling.

In addition, in the folding safety fence that can be reduced-storage and expansion installation, a separate fixing plate is fastened and formed on the connecting pins of each end of the support link connected diagonally to each other, and the upper side of the guide plate capable of separately reduced torsional storage The metal ring is formed by a riveting fixed fastening hole, respectively, by fixing the fixing plate and the guide sphere by a separate fastening bolt and fastening nut, and serves as a safety mark with a relatively simple configuration and parts only It is possible to expand the display and improve the visibility by the safety indicator which can be made in size. It is easy to assemble and dismantle, so it is easy to work even when installing and dismantling the safety fence. Removable safety signs with very economical features that enable mass production Bar has proposed a folding safety fence having a combined structure.

 However, the safety indicator of the safety fence as described above has a fastening structure fixed only at its tip, when the external force, such as wind blowing, is generated fluttering and failing to fulfill the original purpose, as well as frequent fluttering However, the fastening portion of the tip is easily broken and damaged by the flow, which causes the service life to be greatly reduced.

 In particular, the fixing plate for fixed installation of the safety indicator is to be assembled separately to the cross-shaped link, which causes a considerable process addition and delay in the production process, which is a very uneconomical and the main factor that reduces productivity It is becoming.

 In addition, the prefabricated safety fence made of plastic material is light in weight, reduces the risk of accidents, and is easy to move, install and dismantle.

Therefore, an object of the present invention is to quickly and easily adjust the length between the support using a folding type, by using a support consisting of two legs curved in the horizontal direction of the guide signs, so as not to be conducted by the wind, the reflective material It is to provide a safety fence that includes a luminous material, so that pedestrians and drivers can identify at night.

The adjustable length safety fence according to the present invention for achieving the above object includes a folding guide plate horizontal, a support having two legs made of a curved shape.

Preferably, the method further includes adding a reflective material or a luminous material to the horizontal side of the guide plate.

 In addition, the guide plate horizontal portion is characterized in that the length can be adjusted to fit the site.

  In addition, the support is a separate type for storage and movement, and further includes to be fastened and fixed to the guide plate horizontal portion by the fastening portion in use.

In addition, the fastening portion further includes a plate spring to be fixed according to the thickness of the guide plate to be fastened according to the length adjustment.

 In addition, the support further includes a material that is easy to transport and less damage.

 In addition, the foldable guide sign horizontal portion is characterized in that the light, durable material.

According to the invention. By adjusting the length of the guide sign by the folding type, it is possible to install it on the boundary of construction site with only a small amount of safety fence at the time of installation. By making it recognizable, it is possible to minimize the risk of human accidents and to use it as a semi-permanent reflective and luminous material in the long term.

In addition, due to the plate spring of the fastening portion of the support plate after adjusting the length of the guide plate horizontal portion can also be fixed according to the thickness, it can be prevented from being conducted by the curved support.

In addition, it is possible to reduce the effort of installing a number of safety fences in the installation by using a folding type in the site, not a straight part.

 Therefore, the present invention has a very excellent effect of contributing to the safety of pedestrians and drivers, such as easy to install, transport and dismantle, economical and can be identified at night, greatly reducing the risk of safety accidents.
