Roof panel use for building and method of production

The present invention relates to a building roofing panel used as a roofing material of a building, and a method of manufacturing the same.

More specifically, the first and second galvanized steel sheet, which is a galvanized steel sheet or color coated steel sheet, the polyurethane heat insulating material filled and foamed inside the first and second galvanized steel sheet, which is a heat insulating material, and the second zinc steel sheet, It relates to a building roofing panel composed of a thermoplastic polyolefine sheet which is a waterproof sheet integrally bonded to the outside, and a method of manufacturing the same;

Outside the roofing of the building, the building roofing panel of the present invention configuration is installed, the wind pressure and load bearing capacity by the external wind is reinforced by the building roofing panel,

The problem that the waterproof sheet breaks or deforms due to breakage or decrease in wind pressure resistance due to the fall of building accessories such as bolts used in the construction site due to the decrease in tensile strength of the waterproof sheet, which is a roofing sheet of the prior art, Solving the problem that the roofing material is bent or deformed due to the leakage of the roofing material due to the leakage of the roofing material, the damage of the waterproof sheet due to the movement of the worker from the outside of the roofing material or the reduction of the load bearing capacity of the roofing material;

In particular, it is possible to prevent the inflow of water, such as rainwater indoors, so that the waterproofness of the building roofing material is excellent, and the wind pressure resistance of the building roofing material is strengthened,

Load bearing capacity, impact, tensile strength and weather resistance of building roofing materials are strengthened, so that the roofing materials are not deformed or damaged;

It is easy to manufacture and install the building roofing material to improve productivity and workability; The present invention relates to a building roofing panel and a method of manufacturing the same.

In general, the building roofing material is a basic aggregate (PURLIN), which is a basic aggregate corresponding to the structural part of the roofing material, and a steel plate, which is a deck plate (DECK PLATE), which is a base material to which the roofing material and insulation are fixed to the outside of the middleway,

The heat insulating material for the thermal insulation is laminated on the outside of the steel sheet, and the waterproof sheet, which is a roofing sheet for use for reinforcing the wind resistance and waterproofness of the building roofing material, is laminated on the heat insulating material.

As shown in Figure 7, the prior art building roofing material 500;

A middle purlin 541 (PURLIN) of the roofing material 540 and a steel plate 542, which is a deck plate used for a support frame, are installed outside the middle purlin 541.

Insulating material 543 is laminated to the outside of the steel sheet 542, the waterproof sheet which is a roofing sheet for the purpose of reinforcing the waterproofing performance and the wind pressure resistance performance of the roofing material 540 on top of the insulating material (543) 510 is laminated structure,

The roof sheet 540 in which the waterproof sheet 510 is fastened and fastened to the fastener fastener 530 of the fastener fastening hole 522 of the visible fastener 520 that is a fastener to the heat insulating material 543 and the steel plate 542 that is the deck plate. In the installation configuration of),

The visible fastener 520, which is a fastener, is stacked on the upper part of the sheet 1 511, which is the waterproof sheet 510, and the barbed 524 Barbed of the visible fastener 520 is inserted into and insulated from the insulating material 543. Car fixed and,

The fastener 530, which is a fastener, is fastened to the fastener fastening hole 522 provided at the center portion of the visible fixture 520, so that the sheet 1 511, which is the waterproof sheet 510, is a heat insulating material 543 and a deck plate. Fixed to the steel plate 542 and installed;

In order to extend the sheet 1 (511) which is the waterproof sheet, the sheet 2 (512) is laminated on one side of the sheet 1 (511) so that the hot air welding portion 513 that is one side of the sheets 1,2 (511,512). Hot-weld welding, and the sheets 1,2 (511,512) of the waterproof sheet 510 are bonded and the waterproof sheet 510 is fixed to the heat insulating material 543 of the roofing material 540 and the steel plate 542 of the deck plate, It consists of installed structure.
