1 is a schematic diagram schematically showing a curtain mechanism according to the present invention

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a curtain mechanism for shielding the outside of the formwork at the construction site. The curtain mechanism that shields the outside of the formwork mainly blocks the dust and noise caused by the construction work, but it is expected to act as a safety net that prevents the fall of workers, as well as the falling of materials, tools and accessories. .

First, the present invention has a structure in which a sound absorbing material 22 for absorbing sound is laminated between the sheet-like base material 10 and the sound insulating material 25. The base material 10 uses a glass cloth or a sheet having the same or more properties. The most required physical property of the base material 10 is mechanical strength (tensile strength), and may additionally add light shielding properties or flame retardancy. The size of the base material 10 is determined in consideration of the ease of carrying by the vehicle and the ease of installation by the operator. The sound insulating material 25 uses a PVC-based sheet. The sound absorbing material 22 is laminated | stacked between the base material 10 and the sound insulation material 25, Preferably it is accommodated in two layers, and is completed in an integrated sheet structure.

At this time, according to the present invention, the sound absorbing material 22 is preferably made of polypropylene (PP) or nonwoven fabric having pores. Porous polypropylene (PP) or nonwoven fabrics vary in sound absorption depending on the type of fiber, fiber diameter, thickness, porosity, pore size, fiber orientation, bonding point density, sum state, consolidation, surface treatment, etc. . In the sound absorbing material 22 of the formwork shielding curtain mechanism, the porosity and the size of the hole should be selected as particularly important physical properties.

On the other hand, it is also possible to attach a separate cloth for the blackout cloth or other uses to block sunlight or welding light on the base material 10. When using a flame retardant sheet is selected aramid fiber (aramid fiber) or flame retardant polyester, it is attached to the outermost of the base material 10 by sewing or adhesive. Aramid fibers have a high flame retardant performance among the organic fibers, and generates less toxic gas or smoke, and flame retardant polyesters have a lower flame retardancy but are cheaper and easier to process. Accordingly, it is possible to greatly reduce the risk of fire caused by welding sparks or other flames at the construction site.

In addition, according to the present invention to produce the finished product of the square with a quilted seam 35 so that the air pocket 30 is formed between the laminated. The quilted sewing line 35 is formed by sewing the shape of the base material 10 and one sound absorbing material 22 adjacent thereto to cross in the X direction. The other sound absorbing material 22 and the sound insulating material 25 are completed by laminating the edges as they are, without being sewn. Accordingly, the air pocket 30 is formed in a portion where the quilted seam 35 does not pass, contributing to sound absorption. Joined finished product may be formed in a pentagonal or octagonal, but it is usually preferable to have a rectangular shape for the convenience of construction.

Of course, it is also possible to form the quilted barding line 35 on the base material 10, the multilayer sound absorbing material 22, and the sound insulating material 25. In addition to the base material 10, the multilayer sound absorbing material 22, and the sound insulating material 25, all the quilted barding lines 35 can also be formed.

In addition, according to the present invention is a structure for installing a plurality of metal rings 42 on the edge of the finished product. The metal ring 42 is a structure having a hole in the center, and is used for fixing to a member supporting the formwork with a wire or a string. The metal ring 42 is attached to the upper and lower sides of the rectangular finished product at regular intervals. Of course, if the size of the finished product is large, the metal ring 42 may be further attached to the left and right sides.

At this time, as another modification of the present invention, it is also possible to further include a Velcro tape 45 to improve the airtightness at the edge of the finished product. Velcro tape 45 is arranged so that the female and male close to each other to be closely connected to each other when installing the finished product. Velcro tape 45 is disposed in a position that does not significantly deviate from the metal ring 42.

The finished curtain of such a structure is connected to the upper and lower left and right so as to overlap one by one fixed to the member supporting the formwork to prevent dust, noise, shading, fire, etc. generated at the construction site at the same time. In addition, the metal ring 42 and the Velcro tape 45 are easily connected to the casing of the high-noise equipment such as air compressors, and can be easily attached to each other, thereby greatly improving the sound insulation function of the noise source.

Therefore, although the present invention is shown and described to apply to the formwork, it can be applied to various industrial fields.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
