Description

Temporary type guardrail post

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to props of temporary railings that are installed to prevent a worker from falling on the scaffold for temporary temporary works during construction of various building structures. It is a hypothetical handrail holder which enables stable connection fixing without disturbing the movement or work of the worker.

When constructing internal and external materials of undercarriage or when drying ships, temporary temporary objects such as scaffolding are installed outdoors and indoors to be used as a work space for workers. Temporary railings are installed in these temporary objects to prevent the fall of workers or building materials. Will be installed.

Preliminary utility model No. 20-0284897 shows an example of a temporary handrail column which is widely used in ship construction. Looking at this, the hooks are rounded with round ends at the upper outer side and the outer center of the pipe-shaped railing column. Is installed at intervals, and the lower part of the railing column is provided with a clamping means for screwing the fixed end to install the temporary railing, the railing hooks are installed on both sides of the top and the center of the railing column, and the upper part of the railing column. In front of the center and the central part, the 'c' shaped brackets having wedge holes formed at fixed intervals from the vertical part in the upper and lower horizontal parts are fixedly installed, and the lower end of the railing column is provided with a clamp as a clamping means. .

The pre-registration proposal is that the handrail is fixed to the handrail pillar by inserting a handrail such as a pipe into the bracket and inserting a wedge through the wedge hole.

However, the above-described preliminary design is a form in which the wedge is located inside the pipe railing, that is, the railing is located inside the railing column, and the wedge is located in the inner side thereof. Consists of protruding shapes.

The facilities protruding into the railing column in the interior places a lot of restrictions on the worker's movement or work, and even minor protrusions on the clothes during the movement or work may interfere with the work and cause a fatal risk that can lead to safety accidents. It is pointed out as an element.

Particularly, the wedge is made of metal and has not been machined on the outer surface. It is easy to tear clothes, damages and damages other moving materials. It is a product that gives.

In addition, when the wedge is positioned to the worker's work space as described above, the wedge may be detached from the wedge hole due to contact with the worker or other moving material, which may cause a safety accident due to the loss of the function of the railing itself. There are also problems that can be caused.

Due to these problems, a temporary handrail of the form as shown in FIG. 1 has recently been used.

In the temporary handrail 10 in FIG. 1, a clamp 12 is provided at a lower end of the handrail holder 11, and the handrail holder 11 is fixed to the temporary scaffold 20. Coupling protrusions 13 are protruded from both sides of the upper and middle portions, and coupling recesses 16 are coupled to the coupling protrusions 13 at the ends of the pipe railings 15 to be coupled to the coupling protrusions 13. It is fixed by the wedge 17 in the state in which the recessed part 16 was engaged.

Therefore, the wedge 17 is located on the side of the handrail holding 11 without protruding into the temporary handrail holding 11, it is possible to reduce the contact with the worker or other materials working on the inside of the handrail.

However, the following problem has been pointed out in the technique of FIG.

That is, since the pipe railing 15 is connected to the side of the railing column 11, the distance between the railing column 11 and the railing column 11 must be maintained accurately so that the connection assembly of the pipe railing 15 can be made accurately. However, if the distance is not correct, the pipe railing can not be connected.

Depending on the actual working environment, the installation intervals of the railing column 11 may not be made accurately in many cases, so that there are many problems in the installation work of the pipe railing stand 15.

In addition, since only the pipe railing of a specific structure as shown in the drawings should be used, it is not possible to install a railing using a pipe that is widely used in general, which has increased the overall installation cost.

In addition, since the precise installation interval is difficult, the coupling protrusion 13 and the coupling recess 16 of the railing column 11 and the pipe railing 15 are coupled with a large amount of play, which means that the overall binding structure of the railing structure is firm. There was a problem that there is a risk of a safety accident.

The present invention has been made in view of the above-described problems of the prior art, to provide a temporary handrail holder that can minimize the protruding of the wedge for fixing the handrail and pipe handrails to the inside of the temporary handrail in forming the temporary handrail.

Wedge grooves 121 and 122 for fixing the wedge 120 are formed around the recess 117 in the upper plate 113 and the lower plate 114 of the bracket 112.

Although two wedge grooves are formed in the drawing, one or two may be configured around the recess 117, and the wedge 120 to be applied here uses a plate-shaped wedge 120 that is gradually narrowed downward. To this end, the wedge grooves 121 and 122 are also made in a shape suitable for this, and preferably, as the wedge grooves 121 and 122 are formed on the side of the recess 117, the wedge 120 is installed at the time of installation of the wedge 120. It will be located on the side of the railing.

In addition, according to the shape of the wedge 120, the wedge grooves 121 and 122 have a shorter length of the wedge groove 122 of the lower plate 114 than the wedge groove 121 of the upper plate 113, and each wedge groove. The sides in contact with the pipe balustrade 130 at 121 and 122 are vertically aligned with each other.

In addition, the width of the lower wedge groove 122 may be wider than the width of the upper wedge groove 121 so that the wedge 120 may be easily installed.

In addition, the wedge 120 has a locking protrusion 123 protruding toward side surfaces of the upper and lower ends so that the wedge 120 is not easily separated from the wedge grooves 121 and 122 when the wedge 120 is installed.
