Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method and apparatus for manufacturing a heat insulating board material for construction, which has a heat insulating board within a three-dimensional framework made of wire or thin rods.

PRIOR TECHNOLOGY A structure in which a porous plastic having thermal and soundproofing properties is formed in a three-dimensional frame with relatively high structural strength and used as a prefabricated wall material for a building is patented in the United States. No. 3305991 and Korean Utility Model Registration No. 23693. This US Patent No. 3305991 and Korean Utility Model Registration No.
The specification with No. 23693 introduces a method for manufacturing architectural foam panels, and Korean Patent No. 12374
No. 6,006,602 describes a method for manufacturing architectural foam panels in a largely manual manner.

According to the above-mentioned U.S. patent, after each three-dimensional frame is manufactured individually, water is poured into a molding box, and a predetermined area is formed between the bottom of the frame and the bottom of the form to be molded in the liquid stored in the molding box. The three-dimensional framework is immersed so that there are gaps between them. A film-forming liquid is then dropped onto the surface of the water to form a film, after which a liquid foam material is poured over and allowed to harden. At this time, the liquid foam material is poured so that the foam is maintained at a predetermined distance from the top surface of the skeleton.

Furthermore, according to Korean Utility Model Registration No. 23693, plastic foam is inserted between the two side frames on the left and right sides of the truss pattern, and after assembling these multiple pieces sideways with close lines, the side frame box is assembled. The upper and lower parts of the frame are welded together using horizontal wires to provide a three-dimensional fixation.

According to Korean Patent No. 12374, after manually inserting a longitudinal wire into a plastic insulation board, the upper and lower parts are manually inserted into a flat wire mesh placed at a predetermined distance from the plastic insulation board. We are currently welding them to produce insulation boards for construction.

Problems to be Solved by the Invention Among the above methods, the method shown in U.S. Patent No. 3,305,991 requires expensive and special manufacturing equipment to manufacture the three-dimensional framework, and therefore requires a huge capital investment. must be done. In addition, since each foam must be molded one by one in a molding box, it is difficult to mechanically mass-produce foam panels.

In addition, the method of Korean Utility Model Registration No. 23693 has the drawback that it cannot provide sufficient heat insulation and soundproofing properties because minute gaps are created between adjacent individual insulation boards, and it requires a complicated manufacturing process. There are some drawbacks as well.

In addition, although Korean Patent No. 12374 does not require expensive equipment investment, the entire manufacturing process relies on manual methods, making it unsuitable for mechanical mass production.

The manufacturing method of the present invention takes into consideration the problems of the prior art as described above, and is characterized by combining manual methods and mechanical continuous processes to manufacture thermal insulation materials for buildings with relatively simple equipment. It is.
