Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a four-tongue-and-groove color steel composite panel. Background Technology

[0002] Color-coated steel composite panels are widely used in the exterior wall and roof cladding systems of large buildings such as industrial plants and warehouses due to their advantages such as lightweight, high strength, convenient construction, and certain thermal insulation properties. Currently, the mainstream color-coated steel composite panels for factory use typically employ a conventional installation method of "double tongue and groove joints in the long direction, no tongue and groove joints in the short direction." Specifically, two matching tongue and groove joints are provided along the length of the panel (usually the vertical direction in vertical installation) to allow for interlocking between upper and lower panels. However, no tongue and groove structure is designed in the width direction (i.e., the left-right direction); adjacent panels are simply joined flat in this direction, and then covered and fixed by additional, independent edge trim panels or strips. This traditional connection method has several significant drawbacks:

[0003] 1. Poor overall aesthetics of the facade: Due to the lack of tongue and groove joints on the short side, there are obvious straight seams between adjacent panels. Installation errors are unavoidable during installation, resulting in inconsistent joint widths and difficulty in maintaining perfect straightness. Furthermore, the later-added trim panels may have slight differences in material, color, and texture from the main panels, and their protruding shape disrupts the continuity of the panel surface, making the building facade appear fragmented and disjointed, severely impacting the visual appeal.

[0004] 2. Potential Leakage Prevention Performance: The waterproofing of short-direction joints relies entirely on the physical covering of sealant filled into the joints and external sealing panels. The sealant, exposed to the outdoors for extended periods, is susceptible to aging, cracking, and hardening due to UV radiation, temperature cycles, and structural deformation, allowing rainwater to seep in through the joints. Gaps may also form at the overlap between the sealing panels and the board surface due to wind vibration and thermal stress, creating pathways for rainwater leakage. This compromises the reliability of the factory's waterproofing, potentially impacting the internal production environment and equipment safety.

[0005] 3. Structural integrity and installation efficiency issues: Short-range connections are relatively weak, relying mainly on purlins and self-tapping screws for fixing, lacking direct, mechanical interlocking between panels. Under wind loads (especially negative wind pressure), deformation and stress concentration easily occur at the panel joints. Furthermore, the installation process is complex, requiring the main panels to be installed first, followed by joint treatment and installation of finishing panels, increasing construction steps and labor costs, demanding high construction precision, and resulting in low efficiency.

[0006] Therefore, there is an urgent need to develop a color steel plate composite structure that can fundamentally solve the problem of short-distance connections, improve the overall aesthetics of the building facade, enhance its waterproof performance, simplify the installation process, and improve the integrity and durability of the enclosure system. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a four-tongue-and-mortise color steel composite panel, which achieves a tight connection between the panels by setting tenon-and-mortise joints on all four sides, thereby improving the overall aesthetics and anti-leakage performance.

[0008] This utility model discloses a four-tongue-and-groove color steel composite panel, comprising a panel body with tongue and groove structures on its four edges, including an upper tongue and groove edge, a lower tongue and groove edge, a left tongue and groove edge, and a right tongue and groove edge. The upper and lower tongue and groove edges are constructed with interlocking tenon and mortise structures, and the left and right tongue and groove edges are also constructed with interlocking tenon and mortise structures, so that the tongue and groove of adjacent panels on all four sides can fit tightly together.

[0009] Furthermore, the mortise and tenon structure includes a protruding connecting part on one tongue and a recessed connecting part on an adjacent tongue and tenon side, wherein the protruding connecting part and the recessed connecting part are fitted together.

[0010] Furthermore, the cross-section of the protruding connection portion, from the edge of the plate outward, includes, in sequence: a protrusion, a ramp surface disposed on one side of the protrusion and extending obliquely, and a sealing flange disposed at the end of the ramp surface and extending outward.

[0011] Furthermore, the cross-section of the recessed connection portion includes, from the edge of the plate inward, a groove conforming to the protrusion, a stepped mounting plane corresponding to the slope, and a limiting groove conforming to the sealing edge.

[0012] Furthermore, the stepped mounting surface is used to install connecting screws for fixing the plate.

[0013] Furthermore, a plurality of spaces for accommodating sealing material are formed between the mating surfaces of the sealing flange and the limiting groove.

[0014] Furthermore, the space is sealed by providing sealant and / or rubber sealing strips.

[0015] Furthermore, the plate body includes an insulation core layer and a color steel plate layer covering its outer side. The protruding connecting part and the recessed connecting part are stamped and formed by the color steel plate layer and wrap around the end of the insulation core layer.

[0016] The beneficial effects of this utility model are as follows: The four-tongue-and-groove color steel composite panel of this utility model can achieve tight connection in all four directions (up, down, left, and right) of the panel, improving the overall installation flatness and aesthetics; the use of tenon and mortise structure combined with sealing materials effectively prevents rainwater penetration and improves waterproof performance; the structure is reasonable, the installation is simple, and it is suitable for large-area factory exterior wall construction; at the same time, the insulation core layer is integrally formed with the color steel panel, resulting in high structural strength and good insulation effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] As shown in the figure, this embodiment provides a four-tongue-and-groove color steel composite panel, which is mainly composed of a panel body. The four edges of the panel body are each provided with a unique tongue-and-groove structure, specifically including an upper tongue-and-groove edge, a lower tongue-and-groove edge, a left tongue-and-groove edge, and a right tongue-and-groove edge. The upper and lower tongue-and-groove edges are designed with interlocking mortise and tenon joints, and similarly, the left and right tongue-and-groove edges also employ a similar mortise and tenon joint design. This design allows adjacent panels to fit tightly together during installation through the tongue-and-groove structure, thereby ensuring the stability and sealing of the overall structure.

[0022] In this embodiment, the mortise and tenon structure specifically includes a protruding connecting part on one tongue and groove edge and a recessed connecting part on an adjacent tongue and groove edge. The protruding connecting part and the recessed connecting part fit together when connected to form a firm and reliable connection, effectively preventing displacement and loosening between the boards.

[0023] In this embodiment, the cross-section of the protruding connection part includes, from the edge of the plate outward, a protrusion 3, a ramp surface 5 that is disposed on one side of the protrusion 3 and extends obliquely, and a sealing flange 6 that is disposed at the end of the ramp surface 5 and extends outward. This design not only facilitates guidance and alignment during installation, but also enhances the tightness of the connection through the ramp surface 5 and the sealing flange 6.

[0024] In this embodiment, the cross-section of the recessed connection portion includes, from the edge of the plate inward, a groove 4 conforming to the protrusion 3, a stepped mounting plane 8 corresponding to the slope surface 5, and a limiting groove 7 conforming to the sealing edge 6. The fitting of the groove 4 with the protrusion 3 ensures the stability of the connection, while the stepped mounting plane 8 and the limiting groove 7 provide additional fixing and sealing support.

[0025] In this embodiment, the stepped mounting plane 8 is mainly used to install the connecting screws 11 of the fixed plate, thereby firmly connecting the plate to the supporting structure, such as a wall or frame, to ensure the overall building is sturdy and durable.

[0026] In this embodiment, multiple spaces for accommodating sealing material are formed between the mating surfaces of the sealing flange 6 and the limiting groove 7. These spaces, through careful design, can effectively accommodate sealing elements, thereby enhancing the sealing performance of the connection and preventing the influence of the external environment.

[0027] In this embodiment, an effective seal is formed in the space by setting sealant 10 and / or rubber sealing strip 9. The combined use of sealant 10 and rubber sealing strip 9 can effectively prevent the penetration of moisture, air and dust, and improve the insulation and durability of the composite board.

[0028] In this embodiment, the panel includes an insulation core layer 1 and a color steel plate layer 2 covering its outer side. The protruding connecting part and the recessed connecting part are stamped and formed by the color steel plate layer 2 and wrap around the end of the insulation core layer 1. This structure not only protects the insulation core layer 1 from damage, but also enhances the overall strength and aesthetics of the panel, and is suitable for various building envelope systems.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
