Abstract

The present invention relates to a support apparatus for installing a safety net capable of preventing falling accidents in an installation process of a safety net, and more particularly to the support apparatus for installing a safety net in which a moving body fixed to a building wall and coupled to an outer part of the safety net by rotation of a moving shaft is moved to the outer direction from the building wall along a support to unfold the safety net. In the process of moving the moving body, a multi-stepped supporting frame is extended and the length is extended so that the length of the support can be shortened to improve storage and transportability when not in use.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a support apparatus for a safety net,

More particularly, the present invention relates to a supporting device for installing a safety net, which can prevent a falling accident during installation of a safety net, and more particularly, In the process of moving the moving object, the multi-stepped supporting frame is extended and the length is extended. In case of not using the frame, the length of the supporting frame is shortened to improve the storage and transportability The present invention relates to a supporting apparatus for mounting a safety net.

When building a building of a certain height or more, a safety net is installed at a certain height on the outer wall of the building to reduce the damage when a worker falls down and to prevent safety accidents caused by falling of building materials or other articles.

In the conventional safety net, a frame of a certain size is installed at a rim portion, and since the frame is formed to have a constant width, a plurality of continuous frames are continuously connected to the outer surface of the building. A safety net is installed in such a manner that a support member of a ladder type is protruded to the outside and a worker directly climbs the upper part of the ladder to secure the frame of the safety net to the hook of the protruding end of the support frame. In this way, the safety net installed to prevent the fall of the building builder does not guarantee safety to the actual safety net installers. In fact, since the installer has many accidents that fall during the safety net installation process, A safety net installation structure is required.

In addition, since most of the support rods for installing the safety net are integrated in a ladder shape, a large storage area is required.

Korean Patent Laid-Open No. 10-2005-0037804 (published on April 25, 2005; hereinafter referred to as "Prior Art 1") has proposed a safety net structure. In the prior art 1, the first clamp and the second clamp, which are respectively welded to the lower ends of the vertical columns of the first ladder support frame, are clamped to a pedestal fixed to the lower layer of the building, and both ends of the pedestal are clamped by the first triangular bracket The first and second triangular brackets are fixed to the lower layer of the building, the third clamp is welded to the upper surface of the uppermost vertical frame of the first ladder support frame, and the flat surface is welded to the rear surface of the third clamp A plurality of other ladder support frames are installed at predetermined intervals in the building with the same structure as that of the first ladder support frame, A safety net is disposed on a ladder support frame, a wire rope constituting a rim of the safety net passes through a third clamp, and a front end of the safety net is fixed to a ladder support frame, By the control rope is characterized in that the coupling parts of the vertical poles of the ladder support frame at both sides of the safety net.

In the prior art 1, since the ladder support frame is vertically installed, then the safety net is fastened, and the ladder support frame is lowered at an installation angle so as to protrude from the building, the worker directly goes to the end of the ladder support frame protruding outside the building, It is possible to install the safety net without the need. However, since the safety net must be secured at a position close to the outer wall of the building, the risk of safety accidents is still inherent.

Korean Registered Patent No. 10-1049173 (Registered on July 7, 2011; hereinafter referred to as 'Prior Art Document 2') provided a safety net installation site. The prior art document 2 includes two horizontal support bars opposed to each other in the longitudinal direction on both sides and each having a front portion bent inward and a reinforcing bar welded inward; A guide frame coupled to an upper portion of the two horizontal support bars by welding and elongated in a longitudinal direction of the horizontal support bar and having a through hole formed at one end thereof; A fixed drum coupled to an inside of a tip end of the guide frame; A movable pulley formed at a position corresponding to the fixed pulley, and a locking part coupled to the movable pulley at the front end side and hinged to the rear end side by its own load, and a safety net is hooked on the upper end, A safety net hook portion which is inserted into the guide frame and is lifted and lowered along the inside of the guide frame; And a hooking portion for hooking the locking portion formed on the rear end side of the safety net hanger portion.

The prior art document 2 has a merit that the safety net hook provided in the guide frame is moved by the pulley and the pulling bar, and the safety net is installed in the safety net hook portion so that the safety net can be deployed even when the operator does not go outside the building. However, in the prior art document 2, since the horizontal frame is composed of one frame, the storage and transportability when unused or moved is inferior, and an additional safety net must be installed in the outer area of the corner of the building separately from the building surface. As a result, there is a need for a support device for installing a safety net for a new structure to solve this problem.
