[0002] In recent years, flexible roll roofing systems have become the mainstream roofing structure for steel structure factories in my country due to their low cost, fast construction, light weight, excellent seismic resistance, high environmental performance, and compliance with national energy conservation and emission reduction requirements. Traditional flexible roofing systems typically consist of corrugated steel sheets, vapor barriers, insulation layers, and waterproofing layers. These multiple layers are constructed independently and in layers. This practice can damage other structural layers during construction due to cross-construction, compromising their functionality.

The screws between the roll material and the sandwich panels are not conducive to the smooth laying of the roll material. During the laying process and long-term use, the screws are prone to scratching or even cutting the roll material, causing roof leakage, affecting the safety performance of the roll material, and then affecting the safety performance and reliability of the entire roof structure.

[0045] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0046] The utility model relates to a sandwich panel coil roof connection structure, such as Figure 1-7 As shown, it includes a main purlin 2, multiple sandwich panels 1 and a connecting structure component; the bottom of the sandwich panel 1 has a crest structure 3; the sandwich panels 1 are spliced ​​and connected by a connecting structure component; the connecting structure component includes a male and female buckle 7 and a connecting component; the male and female buckle 7 includes a male opening 71 and a female opening 72; one of the two adjacent sandwich panels 1 has a male opening 71, and the other has a female opening 72 that matches the male opening 71, and the two sandwich panels 1 are overlapped and connected by matching the male opening 71 with the female opening 72; the top surface of the sandwich panel 1 is provided with a prefabricated hole corresponding to the crest joint 3 for accommodating the connecting component, and the connecting component is configured to be able to be installed in the prefabricated hole to fix the sandwich panel 1 to the main purlin 2.

[0047] Traditional flexible roof systems are usually composed of corrugated steel sheets, vapor barriers, insulation layers, and waterproof layers. The multiple structural layers are constructed independently and in layers. This practice may damage other structural layers due to cross-operation during the construction process, affecting their functionality. In this application, the corrugated steel sheets and insulation panels are integrally formed in the factory. Only the integrally formed sandwich panels 1 are spliced ​​at the construction site, and then the coil 4 is laid on the spliced ​​sandwich panels 1. The wind resistance, insulation and waterproofing of the roof base can be achieved in one installation. In addition, this application The top surface of the sandwich panel 1 is provided with a prefabricated hole corresponding to the boss. By installing the connection component into the prefabricated hole, the connection component will not protrude from the top surface of the sandwich panel 1. Therefore, in the process of laying the coil 4 on the top surface of the sandwich panel 1, the protruding connection component will not cause damage to the coil 4, such as scratching, puncturing, etc., thereby preventing roof leakage, so that the entire sandwich panel 1 coil 4 roof connection structure can meet the current building waterproofing specifications and the first-level roof waterproofing requirements, thereby improving the waterproof performance and safety performance of the coil 4. The present application can achieve the purpose of hiding the connection component in the prefabricated hole, and can also further ensure that the surface of the coil 4 when laid on the top surface of the sandwich panel 1 is smoother, without protrusions or wrinkles, further ensuring the efficiency and integrity of the laying of the coil 4, meeting market demand, and facilitating later maintenance and care.

[0048] Furthermore, the connection assembly includes a metal countersunk gasket 5 and a screw 6; the metal countersunk gasket 5 is connected to the prefabricated hole, and the screw 6 can pass through the metal countersunk gasket 5, the sandwich panel 1 and the main purlin 2 to be connected.

[0049] The metal countersunk gasket 5 is used to be placed in the prefabricated hole and can be hidden in the sandwich panel 1, so as to facilitate the laying of the flat coil 4 on the top surface of the sandwich panel 1 without contacting the coil 4 and causing the risk of scratching or puncturing the coil 4; and after the metal countersunk gasket 5 is installed in the prefabricated hole, the screws 6 are passed through the metal countersunk gasket 5, the sandwich panel 1 and the main purlin 2 in sequence to fix them together, thereby realizing the fixed connection between the sandwich panel 1 and the main purlin 2 and completing the installation of the sandwich panel 1.

[0050] Furthermore, the metal countersunk gasket 5 has a raised portion protruding toward the bottom, and the metal countersunk gasket 5 has an opening facing upwards of the sandwich panel 1 , and a cavity for accommodating the colloid is provided in the raised portion and communicated with the opening.

[0051] Specifically, the prefabricated hole has a stepped surface, and the prefabricated hole has a countersunk hole structure, which can make the raised portion of the metal countersunk gasket 5 abut against the stepped surface. The step surface limits the installation position of the metal countersunk gasket 5, thereby realizing the positioning of the metal countersunk gasket 5, so that the metal countersunk gasket 5 can be hidden in the prefabricated hole and can be positioned and installed in the prefabricated hole at the same time; the screw 6 can be passed through the metal countersunk gasket 5, and the screw head part of the screw 6 can be installed in the metal countersunk gasket 5, and the nail head part of the screw 6 can penetrate the rock wool insulation layer of the sandwich panel 1 and the lower metal plate to extend into the main purlin 2 and connect with the main purlin 2. In actual application, before connecting the screw 6 to the metal countersunk gasket 5, a through hole is first opened in the sandwich panel 1 using a hole opener to facilitate the screw 6 to pass through the through hole and connect with the main purlin 2. The raised portion of the metal countersunk gasket 5 is placed downward in the prefabricated hole. Since the base 53 of the metal countersunk gasket 5 described below has a mounting hole 9 for mounting the screw 6, the screw 6 is then passed through the metal countersunk gasket 5, the sandwich panel 1 and the main purlin 2 in sequence to fix them.

[0052] Furthermore, the metal countersunk gasket 5 includes a brim 51, a gasket body 52 and a base 53; the brim 51 is connected to the top of the gasket body 52, and the base 53 is connected to the bottom of the gasket body 52 to form a raised portion; a mounting hole 9 for inserting a screw 6 is provided on the base 53.

Since the base 53 is provided with a mounting hole 9, after the metal countersunk gasket 5 is installed in the prefabricated hole, the screw 6 is passed through the mounting hole 9 and the through hole of the sandwich panel 1, so that the sandwich panel 1 is fixedly connected to the main purlin 2. The sandwich panel 1 is fixedly connected to the main purlin 2 through the metal countersunk gasket 5 and the screw 6. It is tightly fixed on the main purlin 2. Through the coordinated use of the metal countersunk gasket 5 and the screw 6, both the metal countersunk gasket 5 and the screw 6 can be hidden in the prefabricated hole, thereby avoiding the phenomenon that the traditional raised screw 6 will cause the coil 4 to be punctured or scratched when laying the coil 4 on top of the sandwich panel 1, resulting in water leakage on the roof. It can also further ensure that the top surface of the sandwich panel 1 is flat when laying the coil 4, thereby improving the flatness of the laying of the coil 4, and can also effectively protect the workers from being scratched by the screw 6 during the process of laying the coil 4 on site, thereby ensuring the safety of construction.
