Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shielding device for an opening part of a building,

The present invention relates to a shielding device for an opening part of a building, and more particularly, to a shielding device for shielding an opening part (a balcony or a window) of an outer wall of a building to reduce noise and dust generated in the opening part The present invention relates to a shielding apparatus for opening an opening of a gang construction.

Generally, a building such as an apartment, a building, or a shopping mall is constructed by pouring concrete into an outer wall. In order to construct an outer wall of a building, an outer form (hereinafter referred to as "gang form") made of large iron is used. These gypsum protects the outer wall from the external environment while preventing the leakage of water until the concrete is hardened and the role of maintaining the shape and size while the concrete is cured.

However, after the concrete curing is finished, the inner foam is disintegrated and noise and dust are generated. These noises and dusts are emitted to the outside through the open section of the building, which is opened for the formation of balconies and windows, where noise of about 70 to 80 dB is generated.

In order to prevent such noise and dust, it is possible to dismantle the inner foam of the inner mold after shielding the opening part of the outer wall of the building temporarily with a curtain or a panel. However, in order to dismantle the inner mold, And the operation of dismantling the curtain or the panel installed in the opening portion again after the operation of disassembling the inner form is repeated. Therefore, there is a problem that additional manpower is required and time and materials are consumed.

In order to solve such a problem, Korean Patent No. 10-1116464 (Registered on Feb. 02, 2012) and Korean Registered Patent No. 10-1386054 (Registered on Apr. 10, 2014.) have been proposed.

Korean Patent No. 10-1116464 discloses a method of cutting an open section formed in an open wall of a layer which needs to be lifted together with a gangmat and dismantling the inner foam, And a shield plate fixed to the outer frame and blocking only the open section. The present invention provides an open wall shielding system comprising: It is unnecessary to repeatedly install and dismantle work and to block only the open wall of the layer which needs dismantling of the inner foam. Therefore, it is possible to effectively prevent noise, construction material, inner foam And dust and the like are prevented from being discharged to the outside.

However, according to Korean Patent No. 10-1116464, since a fixed frame fixed to a stringer is formed as a pair, a material is further required to increase the construction cost, and since the fixed frame does not extend in the longitudinal direction, The outer frame of the shield plate is lifted in contact with the outer wall of the building in the process of being lifted together with the gang after the completion of the dismantling work, and the outer wall of the building is damaged And the outer frame collides with the building and is damaged.

Korean Patent Registration No. 10-1386054 discloses a soundproof panel comprising a soundproof plate for shielding the opening of a quadrangle formed on a wall, a square support frame for supporting the edge of the soundproof plate, and a panel clip for fixing the soundproof plate to the square support frame so that the soundproof plate can be detachably attached to the square support frame. And a connection bracket fixed to the gang-shaped frame, the noise and dust generated in the process of demolishing the form as shown in Korean Patent No. 10-1116464 are emitted to the outside of the building .

However, in Korean Patent No. 10-1386054, like the Korean Patent No. 10-1116464, since the connection brackets fixed to the vertical columns are formed as a pair, the construction cost can be increased due to additional material, The length of the connection bracket may be adjusted by adjusting the length of the connection bracket in accordance with the size of the soundproof plate. Therefore, the construction may be troublesome and inconvenient. In the process of being lifted together with the gang- The corner portion is lifted in contact with the outer wall of the building, thereby damaging the outer wall of the building, and causing the square support frame to collide with the outer wall of the building, resulting in breakage.
