Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a heat insulation board for prefabricated buildings and a prefabricated building. Background Technology

[0002] With the rapid development of prefabricated buildings, insulation panels, as a primary means of blocking the "thermal bridge effect" and ensuring fire safety, have undergone adaptive changes in materials and structures to better meet the higher energy-saving standards and safety requirements of prefabricated buildings. Currently, insulation materials (such as asbestos, polyurethane, or rock wool and PCM composite sandwich panels) are mainly used to cover the steel structure surface to form an insulation layer to block heat transfer. However, this method relies on on-site construction by workers, and its effectiveness varies, and its actual load-bearing capacity depends on the steel frame structure itself.

[0003] Based on this, Chinese utility model patent document (CN210439506U) discloses a fire-resistant partition wall for prefabricated steel-framed buildings. It utilizes a multi-layered steel plate structure, fire-resistant structure, and internal structure, based on T-shaped and L-shaped trusses as supports to improve its load-bearing capacity while ensuring its fire-resistant and heat-insulating properties. However, the installation of the embedded internal components of the T-shaped and L-shaped trusses is relatively complicated, resulting in high manufacturing costs. Utility Model Content

[0004] This utility model provides a prefabricated building insulation board to solve the problem that the manufacturing cost of insulation boards is high in the prior art in order to ensure fire resistance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to provide a prefabricated building insulation board, which includes: a board body, a fireproof structure, an internal structure, and supporting profiles.

[0006] The panel is symmetrically provided with side rails at both ends along its length; the fireproof structure includes one or more fireproof materials embedded in the panel along its thickness; the internal structure includes one or more panels that can be stacked alternately with the fireproof materials; the supporting profile includes rolled keel and partition wall connecting keel embedded in the panel, wherein the rolled keel is symmetrically embedded in the panel along its thickness.

[0007] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows: By adding a side rail structure, it can serve as the outermost encapsulation structure of the panel, and when applied to prefabricated buildings, it can reduce the assembly difficulty of different insulation panels. Among them, the roll-formed keel refers to the light steel keel manufactured by the roll forming process. It has the advantages of standardized structure and convenient installation. Embedding it into the panel can avoid the cutting and installation of complex irregular materials, and avoid the additional processing work caused by independent and complex embedded truss components and their complicated connection interfaces.

[0008] The connecting keel of the partition wall, as a key load-bearing component of the aforementioned insulation board, is generally applied to the outermost side of the building wall. Embedding it into the board as an intermediate component effectively improves the structural strength, load-bearing capacity, and deformation resistance of the board. Furthermore, the alternating layering of the fire-resistant panels in the fire-resistant structure with the panels in the interior structure effectively ensures its fire-resistant performance.

[0009] In some embodiments, the internal structure includes a first steel plate and a second steel plate arranged at intervals along the thickness direction, and the fireproof material filling the space between the first steel plate and the second steel plate includes rock wool; wherein the rolled keel penetrates the first steel plate and the rock wool along the thickness direction and is locked to the first steel plate and the second steel plate respectively.

[0010] By employing the above technical solution, the rolled keel penetrates and interlocks the first steel plate, the second steel plate, and the fireproof rock wool layer, forming an integral truss structure, thereby significantly improving the plate's resistance to shear deformation. Furthermore, the first and second steel plates respectively constrain the rock wool, preventing fiber shedding and enhancing fire resistance.

[0011] In some embodiments, the internal structure includes calcium silicate boards spaced apart along the thickness direction, wherein the fireproof material filling the spaces between adjacent calcium silicate boards is rock wool. Further, the internal structure includes a first steel plate and a second steel plate spaced apart sequentially along the thickness direction, and the partition wall connecting joists sequentially penetrate the calcium silicate boards and the rock wool along the thickness direction, and are connected to the first steel plates located on both sides of the calcium silicate boards.

[0012] Using the above technical solution, the calcium silicate board provides a flat inner base surface for the internally embedded partition connecting keel. The partition connecting keel penetrates the calcium silicate board and the fireproof rock wool layer to lock with the first steel plates on both sides, ensuring the transmission of force to the main structure and guaranteeing the stability of the board. Furthermore, the first steel plate is a galvanized steel plate, and the second steel plate is a steel composite plate.

[0013] In some embodiments, the plate body is further provided with stabilizing structures on both sides along the length direction. The stabilizing structures respectively include an L-shaped plate welded to the second steel plate and a frame-shaped bracket, wherein the L-shaped plate is locked to the frame-shaped bracket.

[0014] By adopting the above technical solution, the L-shaped plate and the second steel plate can be welded to form rigid side ribs. The frame bracket provides bidirectional constraint force by locking with the L-shaped plate and welding with the second steel plate, suppressing the warping deformation of the plate edge, thereby ensuring the flatness of the wall panel assembly under larger size.

[0015] In some embodiments, the plate body is further provided with bow-shaped supports on both sides along the length direction, and the outer edge of the first steel plate is bent inward and locked with the bow-shaped supports; wherein, the side rail at least partially covers the bow-shaped supports and the first steel plates located on both sides of the bow-shaped supports.

[0016] By adopting the above technical solution, the bow-shaped bracket can further ensure the edge constraint of the plate, and the bending of the first steel plate and the locking of the bow-shaped bracket can form a composite reinforced edge, improving the stability of the plate. Furthermore, the base material of the side rail, the rolled keel, and the partition wall connecting keel is steel.

[0017] In some embodiments, the fire-resistant material further includes corrugated material, wherein the corrugations are located between the second steel plate and the second rock wool along the thickness direction. By employing the above technical solution, selecting a corrugated structure as the fire-resistant material can block airflow and reduce heat convection transfer efficiency. Furthermore, the plate body forms a structure in which the fire-resistant material and the inner lining material are alternately stacked along the thickness direction, wherein the inner lining material includes a first steel plate, a second steel plate, and a calcium silicate board.

[0018] In some embodiments, this application also provides a prefabricated building, including one or more of the above-described prefabricated building insulation panels.

[0019] By adopting the above technical solution, the prefabricated building adopts the above-mentioned heat insulation board structure. Each component of the heat insulation board structure can be pre-produced and then assembled, thereby serving as a non-load-bearing vertical partition component of the prefabricated building. This reduces the difficulty and cost of assembly and ensures its fire resistance performance. Attached Figure Description
