Technical Field

[0001] The utility model relates to the technical field of plates, in particular to an assembled steel structure roof sandwich plate. Background Art

[0002] Prefabricated steel structure roof sandwich panels are a material used for building roofs. They are composed of two layers of steel plates and a thermal insulation material in the middle. They are not only light in weight, but also have strong wind resistance, earthquake resistance, corrosion resistance and fire resistance. Prefabricated steel structure roof sandwich panels have been widely used in the construction field, especially in industrial plants, warehouses, commercial complexes and other buildings. Their superior performance and easy processing and installation make them a very popular building material.

[0003] In the prior art, the steel structure roof sandwich panel is very susceptible to temperature because the upper and lower main boards are made of steel, and gaps are generated due to thermal expansion and contraction. In this way, it is necessary to inject foam glue between the two sandwich panels for bonding to block the gaps.

[0004] However, the traditional method of pouring foam glue requires pouring during the installation of the sandwich panel, which is not only time-consuming and labor-intensive, but also causes overflow due to poor control of the amount, affecting the overall appearance and being very difficult to clean. Therefore, the utility model proposes an assembled steel structure roof sandwich panel to solve the above problems. Utility Model Content

In this case, foam glue needs to be poured between the two sandwich panels for bonding and blocking the gaps. However, the traditional method of pouring foam glue needs to be poured during the installation of the sandwich panels, which is not only time-consuming and labor-intensive, but also causes overflow due to poor control of the amount, affecting the overall appearance and being very difficult to clean.

[0006] To achieve the above object, the utility model provides the following technical solution: an assembled steel structure roof sandwich panel, the assembled steel structure roof sandwich panel comprising: an upper main board, a lower main board is arranged below the upper main board, and an insulation layer is filled and arranged between the upper main board and the lower main board;

[0008] Preferably, the upper main board and the lower main board are both made of steel, and the upper main board and the lower main board have the same specifications such as shape and thickness. The upper main board and the lower main board are in the shape of square plates, and a reinforcing frame is provided around the insulation layer.

[0009] Preferably, threaded holes are provided at the upper end of the upper main board near the four corners, and the threaded holes penetrate the upper main board and extend downward through the insulation layer to be connected to the lower main board.

[0010] Preferably, a plurality of positioning holes are provided at the upper end of the upper main board, and the positioning holes are arranged vertically through the upper main board, and the positioning holes are arranged in a circular array near the surrounding positions of the upper end of the upper main board.

[0011] Preferably, a firmware is installed in the positioning hole, the firmware is fixedly connected to the upper main board by screws, a through groove is opened in the firmware, and a leak-proof brush is provided at the opening of the through groove.

[0012] Preferably, the interior of the capsule is filled with a foam filler, and two discharge ports are opened on the surface of the capsule. The two discharge ports are sealed by two sealing sheets, the bottom end of the sealing sheet is fixedly connected to the bottom end of the pull rod, and the top end of the pull rod is fixedly connected to the pulling strip.

[0013] Preferably, the twitching bar is arranged in the through groove, a handle is fixed on the top of the twitching bar, the handle is arc-shaped, and a non-slip rubber pad is fixed on the arc-shaped inner surface of the handle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model discloses an assembled steel structure roof sandwich panel. By manually turning a handle, a pulling strip and a pulling strip are driven to move upward, so that a sealing sheet falls off. The pulling strip, the pulling strip and the sealing sheet are pulled out from the through groove. The foam filler inside the capsule leaks out and expands rapidly when in contact with moisture in the air, filling the gaps between the sandwich panels. This avoids the problem that the traditional method of pouring foam glue needs to be poured during the installation of the sandwich panel, which is not only time-consuming and labor-intensive, but also causes overflow due to poor control of the amount, affecting the overall appearance and being very difficult to clean.
