Description

Apparatus for opening and closing the shielding plate installed in the open section of the bulding by rotation}

The present invention relates to a device for opening and closing the open part shielding plate of a building by rotation, and more particularly, by a simple rotation operation of the open part shielding plate installed in the open part of the building in the process of constructing the outer wall of the building using gangfoam. By making it easy to open and close, it is possible to prevent external leakage of noise or dust by shielding the open part of the building with the open part shielding plate when dismantling the formwork. If necessary, the open part shielding plate can be arbitrarily opened to pass through the open part of the building. It relates to a rotating opening and closing device for a shielding plate of an open part of a building that enables efficient improvement of an internal working environment by enabling ventilation or lighting.

In general, in buildings such as apartments, buildings, or shopping malls, most of the exterior walls are constructed by pouring concrete.For the exterior wall construction of these buildings, a large steel exterior wall form, that is, gang form is used, and such gang form is used while the concrete is being cured. It maintains the predetermined shape and dimensions, prevents leakage of moisture until the concrete hardens, and protects the outer wall from the external environment.After the concrete curing is completed, it is lifted after dismantling and reused for the construction of the outer wall of the upper floor.

On the other hand, a number of openings for installing windows of various sizes are formed on the outer wall of the building, through which noise and dust generated during the dismantling process of the formwork (euroform, aluminum foam, etc.) are emitted to the outside as it is. In particular, noise and dust caused by collisions on the floor surface of the falling formwork in the process of dismantling the heavy formwork installed on the ceiling of the building cause considerable damage to the surrounding residents and become the main cause of various civil complaints. Legal regulations such as noise vibration and scattering dust prevention are gradually strengthening.

In this regard, Korean Patent Registration No. 10-1116464 (registered on Feb. 7, 2012, name: Open wall blocking system, hereinafter abbreviated as'Patent Document 1'), Korean Patent No. 10-1386054 (registered on April 10, 2014) , Name: Formwork shielding device for building construction, hereinafter abbreviated as'Patent Document 2'), Korean Registered Office No. 20-0479596 (registered on Feb. 6, 2016, title: Shielding device on the open part of building gang form, hereinafter'Patent Document 3) '), etc., it is fixed to the gang form, and when the exterior wall of the building is constructed, the open part of the building is shielded to prevent the leakage of noise and dust to the outside through the open part, and after dismantling the form, it is lifted together with the gang form and A shielding plate that can be reused by shielding the formed opening has been proposed.

However, in general, gangform has a horizontal reinforcement at the lower end of the stringers to reinforce a plurality of stringers, and this horizontal reinforcement is a structure that is arranged so as to overlap the open part of a building while the gangform is installed on the outer wall of a building. In order to install the integrated square plate-shaped shielding plate proposed in Patent Literature 1 to Patent Literature 3 on the stringer, the horizontal reinforcing bar must be cut and removed, and then the shielding plate must be fixedly installed, making the installation work cumbersome and complicated.

On the other hand, the Republic of Korea Registration No. 20-0483370 (registered on April 27, 2017, name: shielding device for the open part of the building, hereinafter abbreviated as'Patent Document 4') has a shielding plate divided up and down by the horizontal reinforcement of the gang form. By proposing a shielding device for the open part of the building including, it was possible to stably construct the divided shielding plate in a state where it remained without cutting and removing the horizontal reinforcement.

In addition, the Korean Registered Office No. 20-0489664 (registered on July 12, 2019, name: shielding plate on the open part of the building, hereinafter abbreviated as'Patent Document 5') is provided with a shielding member for maintaining the gap between the divided shielding plate and shielding the gap. Therefore, it is possible to prevent the leakage of noise or dust to the outside through the gap caused by the gap between the exterior wall of the building and the divided shielding plate.

As illustrated in Fig. 1, the divided shielding plates of Patent Literature 4 and Patent Literature 5 have a top plate 11 installed on the upper side with a horizontal reinforcement plate 4c of the gang form, and a lower side with a horizontal reinforcement plate 4c as a boundary. It is divided into the lower plate 12 to be installed so that the construction of the divided shielding plate is possible while the horizontal reinforcement remains.

However, in the case of the split shielding plate as described above, once installed, it can be separated through the dismantling operation, so it is separated when the formwork is dismantled after the concrete curing is completed, and to improve the working environment due to an increase in temperature or other reasons such as summer. When ventilation, ventilation, or lighting is required, the shielding plate cannot be easily opened, and there are many difficult problems in improving the environment inside the construction site.
