Description

Technical Field

[0001] The utility model relates to the technical field of composite panels, in particular to a seamless composite panel. Background Art

[0002] Composite panels are widely used in modern architecture, primarily in flooring, wall panels, and roof structures. Composite panels play a vital role in construction, not only providing strong structural support but also acting as partitions to divide spaces.

[0003] However, there are some defects in the composite composite panels currently on the market. Common methods of laying and connecting composite panels usually rely on connectors such as screws and steel bars. These connection methods will leave obvious gaps between the panels, which can easily become gathering points for moisture, dust and dirt. The moisture and dust in the gaps will gradually erode the panels, causing aging and damage to the materials. What is more serious is that the connection seams will weaken the overall strength of the panels and increase the instability of the structure. Especially during long-term use, it is easy to cause the panels to loosen or shift, affecting the safety of the building.

[0004] Therefore, there is an urgent need for a seamless composite panel to solve the above technical defects. Utility Model Content

[0005] The purpose of the utility model is to provide a seamless composite board to solve the problem of large connection gaps when the composite boards are laid as mentioned in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seamless composite board, comprising a base plate, a heat insulation board and a waterproof board, comprising a base plate, a heat insulation board and a waterproof board, wherein the base plate, the heat insulation board and the waterproof board are bonded to form a composite board, and a connecting structure is provided at the four corners of the composite board, and the connecting structure includes an interlocking groove and an interlocking strip, and the interlocking groove and the interlocking strip are provided in a group on both sides of each layer of the composite board.

[0007] Furthermore, the engaging groove and the engaging strip are T-shaped.

[0008] Furthermore, the engaging groove and the engaging strip are fixedly connected by bolts.

[0009] Preferably, the substrate is a high-density fiberboard or an aluminum alloy board.

[0010] Furthermore, the thermal insulation board is polyurethane foam or extruded polystyrene.

[0011] Furthermore, the waterproof board is PVC or a waterproof rubber membrane.

[0012] Preferably, a wave-shaped overlapping seam is provided between the base plate, the heat insulation board and the waterproof board, and an adhesive is bonded in the overlapping seam.

[0013] Furthermore, the thickness of the substrate, the heat insulation board and the waterproof board are arranged from large to small as follows: substrate>heat insulation board>waterproof board.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: the seamless composite board not only reduces the weaknesses at the joints, achieves seamless connection, and realizes multiple functions such as waterproofing, heat insulation, and noise prevention, but also prevents the separation and loosening problems caused by thermal expansion and contraction between the layers;

[0015] (1) By providing a connection structure, an interlocking groove, and an interlocking strip, a plurality of composite panels are interlocked and connected through a "T"-shaped interlocking groove and an interlocking strip, and then bolts are driven in, thereby achieving a tight and seamless connection between the panels. Multiple sets of composite panels can be continuously spliced, which not only increases the overall aesthetics of the panels, but also significantly improves the stability of the structure. During the installation process, the connection structure can ensure the alignment and fixation of each panel, preventing loosening or displacement during use. Compared with traditional connection methods, the weakness of the joints is reduced, making the entire panel more durable. In addition, the seamless connection can effectively prevent moisture and dust from entering the joints, protect the internal structure, and increase the service life;

[0016] (2) The seamless composite board adopts a composite three-layer structure by providing a base plate, a heat insulation board and a waterproof board. The base plate is made of high-density fiberboard or aluminum alloy board to provide solid support and structural strength. The heat insulation board is made of polyurethane foam or extruded polystyrene, which has excellent thermal insulation performance and ensures stability under various temperature environments. The waterproof board is made of PVC or waterproof rubber film to effectively prevent moisture penetration and protect the internal structure. The seamless composite board not only has good mechanical properties, but also realizes multiple functions such as waterproofing, heat insulation and noise prevention. It can be widely used in places where high-performance boards are required, such as bathrooms, kitchens, laboratories and cold storages.

[0017] (3) By providing overlapping seams, the wavy overlapping seams of the composite composite board not only improve the overall compressive and tensile properties of the board, but also effectively prevent the separation and loosening problems caused by thermal expansion and contraction between the layers. Compared with the traditional flat bonding method, the application of overlapping seams greatly improves the overall strength and durability of the board, so that it can still maintain excellent performance and stability in various harsh environments and prevent delamination.
