Description

Technical Field

[0001] The utility model relates to a building panel technology, and particularly to a unit component of a hollow building panel. Background Art

[0002] Currently, forming building panels using composite materials has become one of the important development trends. Existing hollow building panels usually have panels on two surfaces and connecting support plates between the two panels. Since the connecting support plates are located between the two panels and are relatively fixed, building panels with suitable strength and stiffness can be formed; at the same time, due to their hollow structure, the weight of the hollow building panels can be significantly reduced.

[0003] Hollow building panels are usually formed by connecting multiple unit components. By changing the number of unit components, a hollow building panel with a suitable area can be obtained. The shape of the structure of the unit component not only affects the mechanical properties of the hollow building panel, but also relates to the connection and fixing method between the unit components, thereby affecting the production efficiency of the hollow building panel.

[0004] Therefore, how to improve the production efficiency of hollow building panels while ensuring the mechanical properties of hollow building panels is an important technical problem that needs to be solved by those skilled in the art. Summary of the Utility Model

[0005] For this reason, the utility model provides a unit component of a hollow building panel. Using this unit component, a hollow building panel can be conveniently formed, and at the same time, the production efficiency of the hollow building panel can be improved while ensuring the mechanical properties of the hollow building panel.

[0006] The unit component of the hollow building panel provided by the utility model is formed by bending a sheet material, that is, it can be formed by bending a complete sheet material, and includes a first panel part, a second panel part and a core board;

[0007] Both ends of the core board are respectively connected to the inner ends of the first panel part and the second panel part through a first connecting folding part and a second connecting folding part; the outer ends of the first panel part and the second panel part respectively form a first sewing flanging and a second sewing flanging that bend inward and toward the inner end;

[0008] The first connecting folding part and the second connecting folding part respectively include a first bending composite section and a second bending composite section that incline outward;

[0009] The first bending composite section and the second bending composite section respectively correspond to the first sewing flanging and the second sewing flanging, so as to facilitate the sewing and fixing between unit components.

[0010] By bending the above unit components formed integrally, they can be sequentially arranged in the cross-sectional direction, and the first bending composite section in the first unit component can be inserted between the first stitched flange and the first panel part of the second unit component; the second bending composite section in the first unit component can be inserted between the second stitched flange and the second panel part of the second unit component; and the first bending composite section of the first unit component is kept in close contact and fixed with the first stitched flange and the first panel part of the second unit component, and the second bending composite section in the first unit component is kept in close contact and fixed with the second stitched flange and the second panel part of the second unit component. Thus, adjacent unit components can be stitched and kept fixed. A number of unit components are sequentially connected and fixed in the same way, and a hollow building panel with appropriate dimensions can be formed. By the cooperation of the first bending composite section in the first unit component and the first stitched flange of the second unit component, a hollow building panel can be conveniently formed. At the same time, between the unit components, by stitching and fixing the first bending composite section in the first unit component and the first stitched flange of the second unit component, and combining the core board to connect the first panel part and the second panel part, while ensuring the mechanical properties of the hollow building panel, the production efficiency of the hollow building panel can be improved.

[0011] In a further optional technical solution, the extension directions of the first panel part and the second panel part are kept parallel. In this way, before and after the hollow building panel is stitched, the relative positions of the first panel part and the second panel part with respect to the core board are the same, which is convenient for reducing the stress of the hollow building panel after stitching, reducing the deformation of the hollow building panel, and improving the stability of the mechanical properties of the hollow building panel.

[0012] In a further optional technical solution, the extension direction of the core board is perpendicular to the extension direction of the first panel part. In this way, the supporting role of the core board can be fully exerted, and the rigidity and stability in the thickness direction of the hollow building panel can be ensured.

[0013] In a further reliable technical solution, the first panel part and the second panel part extend obliquely to both sides respectively. In this way, when stitching the unit components, the conical structure formed by the first panel part and the second panel part can be utilized to facilitate the joining between the unit components, and thus it is convenient for stitching and fixing, which can improve the production efficiency of the hollow building panel and reduce the cost of the hollow building panel.

[0014] In a further preferred technical solution, the first connecting folded edge portion and the second connecting folded edge portion further respectively include a first folding receiving concave portion and a second folding receiving concave portion; the first folding receiving concave portion is connected between the first bending composite section and the first panel portion, and the second folding receiving concave portion is connected between the second bending composite section and the second panel portion; the first folding receiving concave portion and the second folding receiving concave portion respectively form a first folding receiving groove and a second folding receiving groove to receive the stitched folded edge; more preferably, the depths of the first folding receiving groove and the second folding receiving groove are both not less than 4 times the thickness of the unit member plate. In this way, the stitched folded edge can be located within the sides of the first panel portion and the second panel portion, thereby ensuring the flatness of the surface of the hollow building panel and improving the service performance of the hollow building panel.

[0015] In an alternative technical solution, the first panel portion and the second panel portion are symmetrically arranged. This can ensure the flatness of the hollow building panel and avoid skew.

[0016] In an alternative technical solution, the cross-sectional width of the first panel portion is 1.3 to 1.9 times the cross-sectional width of the core board. This can ensure the supporting effect of the panel portion of the core board 30, and thus ensure the strength of the hollow building panel. At the same time, the cross-sectional widths of the first stitched edge and the second stitched edge are both greater than one-tenth of the cross-sectional width of the first panel portion, which can ensure a suitable connection size between the unit members, and thus ensure the reliability of the connection between the unit members in the hollow building panel.

[0017] The hollow building panel provided by the present utility model includes a plurality of unit members arranged in sequence, wherein the unit member is the unit member of the above-mentioned hollow building panel; the first bending composite section in the first unit member is inserted between the first stitched edge and the first panel portion of the second unit member; the second bending composite section in the first unit member is inserted between the second stitched edge and the second panel portion of the second unit member; and the first bending composite section of the first unit member is kept in close contact and fixed with the first stitched edge and the first panel portion of the second unit member, and the second bending composite section in the first unit member is kept in close contact and fixed with the second stitched edge and the second panel portion of the second unit member. Using the unit member to form a hollow building panel can produce corresponding technical effects.

[0018] Similarly, in a further preferred technical solution, the first connecting folding edge portion and the second connecting folding edge portion further respectively include a first folding accommodating concave portion and a second folding accommodating concave portion; the first folding accommodating concave portion is connected between the first bending composite section and the first panel portion, and the second folding accommodating concave portion is connected between the second bending composite section and the second panel portion; the first folding accommodating concave portion and the second folding accommodating concave portion respectively form a first folding accommodating groove and a second folding accommodating groove to accommodate the stitched folding edge. This can also improve the flatness of the surface of the hollow building panel.

[0019] In a further preferred technical solution, the first stitched folding edge in the first unit member is inserted between the first bending composite section and the first folding accommodating concave portion of the second unit member; the second stitched folding edge in the first unit member is inserted between the second bending composite section and the second folding accommodating concave portion of the second unit member; and the first stitched folding edge in the first unit member is kept in close contact and fixed with the first bending composite section and the first folding accommodating concave portion of the second unit member; the second stitched folding edge in the first unit member is kept in close contact and fixed with the second bending composite section and the second folding accommodating concave portion of the second unit member. This can improve the reliability of the stitched connection and fixation between the unit members and enhance the rigidity of the hollow building panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following describes the detailed implementation manners provided by the present utility model. Those skilled in the art can understand that in this patent, the unit member is a strip-shaped member, and its main improved structure is reflected in the cross-sectional structure. Therefore, for the convenience of description and for easy understanding, the orientation terms in this document are mainly determined based on the cross-section shown in the corresponding drawings. For the need of easy understanding and to save space, while describing the unit member of the hollow building panel, the hollow building panel is also described herein.

[0029] Please refer to Figure 1 , Figure 1 which is a cross-sectional structure diagram of a unit member of a hollow building panel provided by the present utility model. The unit member is a strip-shaped object, formed by bending a plate with a predetermined length and width in an appropriate manner. In the embodiment, the plate is a galvanized steel plate with a thickness of 2 mm. The uniqueness of the unit member lies in its cross-sectional structure, including a first panel part 10, a second panel part 20, and a core plate 30.

[0030] Both ends of the core plate 30 are respectively connected to the inner ends of the first panel part 10 and the second panel part 20 through a first connection folded edge part 40 and a second connection folded edge part 50. The connection folded edge part is formed by laminating plates. The first connection folded edge part 40 and the second connection folded edge part 50 respectively include a first bending composite section 41 and a second bending composite section 51 that are inclined outward.

[0031] The outer ends of the first panel part 10 and the second panel part 20 respectively form a first stitching flange 11 and a second stitching flange 21 that are bent inward and toward the inner end, forming a hook shape.

[0032] The first bending composite section 41 and the second bending composite section 51 respectively correspond to the first stitching flange 11 and the second stitching flange 21, so that the unit members overlap each other, thereby facilitating the stitching and fixing between the unit members.

[0033] Please refer to Figure 2 and Figure 3 , Figure 2 which are corresponding diagrams of two adjacent Figure 1 unit members shown in Figure 3The staggered state of the bending composite sections and the stitched flanges of two adjacent unit components is shown. It can be determined that the above-mentioned unit components formed by integral bending can be sequentially arranged in the cross-sectional direction, and the first bending composite section 41 in the first unit component can be inserted between the first stitched flange 11 and the first panel part 10 of the second unit component; the second bending composite section 51 in the first unit component can be inserted between the second stitched flange 21 and the second panel part 20 of the second unit component.

[0034] Refer again to Figure 4 and Figure 5 , Figure 4 which shows the structure of the fitting state of the bending composite sections and the stitched flanges of two adjacent unit components. Figure 5 is Figure 4 the enlarged structure diagram of part A in

[0035] In this embodiment, when bending to form the unit component, the extension directions of the first panel part 10 and the second panel part 20 can be kept parallel. Before stitching adjacent unit components, the first panel part 10 and the second panel part 20 are first opened outward by a suitable device to form a tapered structure, so that adjacent unit components can be staggered. This can make the relative positions of the first panel part 10 and the second panel part 20 and the core board 30 the same before and after stitching to form the hollow building panel, reduce the stress of the hollow building panel after stitching, reduce the deformation of the hollow building panel, and improve the stability of the mechanical properties of the hollow building panel. Of course, when bending to form the unit component, the first panel part 10 and the second panel part 20 can also be extended obliquely to both sides. In this way, when stitching the unit components, the tapered structure formed by the first panel part 10 and the second panel part 20 can be used to facilitate the joining between the unit components, and thus facilitate the stitching and fixing, which can improve the production efficiency of the hollow building panel and reduce the cost of the hollow building panel.

[0036] In this embodiment, the extension direction of the core board 30 is perpendicular to the extension direction of the first panel portion 10. In this way, the supporting effect of the core board 30 can be fully exerted to ensure the rigidity and stability of the hollow building panel in the thickness direction. According to actual needs, the extension direction of the core board 30 can also be set to be inclined relative to the extension direction of the first panel portion 10 to have higher strength or stiffness in certain specific directions.

[0037] Please refer to Figures 2 to 5 , in this embodiment, the first connection folding edge portion 40 and the second connection folding edge portion 50 further include a first folding accommodation concave portion 42 and a second folding accommodation concave portion 52 respectively; the first folding accommodation concave portion 42 is connected between the first bending composite section 41 and the first panel portion 10, and the second folding accommodation concave portion 52 is connected between the second bending composite section 51 and the second panel portion 20; the first folding accommodation concave portion 42 and the second folding accommodation concave portion 52 respectively form a first folding accommodation groove and a second folding accommodation groove to accommodate the stitched folding edge; more preferably, the depths of the first folding accommodation groove and the second folding accommodation groove are both not less than 4 times the thickness of the unit member plate. In this way, the stitched folding edge can be located inside the sides of the first panel portion 10 and the second panel portion 20, thereby ensuring the flatness of the surface of the hollow building panel and improving the service performance of the hollow building panel.

[0038] As described above, arranging and stitching the above unit members in sequence can form the hollow building panel provided by the present utility model. Please refer to Figure 6 and Figure 7 , Figure 6 is an overall screenshot of the hollow building panel provided by the present utility model, Figure 7 is a side view of the hollow building panel provided by the present utility model. In the hollow building panel, the first bending composite section 41 in the first unit member is inserted between the first stitched folding edge 11 and the first panel portion 10 of the second unit member; the second bending composite section 51 in the first unit member is inserted between the second stitched folding edge 21 and the second panel portion 20 of the second unit member; and the first bending composite section 41 of the first unit member is kept in close contact and fixed with the first stitched folding edge 11 and the first panel portion 10 of the second unit member, and the second bending composite section 51 in the first unit member is kept in close contact and fixed with the second stitched folding edge 21 and the second panel portion 20 of the second unit member. Using the unit member to form the hollow building panel can produce corresponding technical effects.

[0039] As described above, in the hollow building panel, the first connecting folded edge portion 40 and the second connecting folded edge portion 50 may further include a first folding receiving concave portion 42 and a second folding receiving concave portion 52 respectively; the first folding receiving concave portion 42 is connected between the first bending composite section 41 and the first panel portion 10, and the second folding receiving concave portion 52 is connected between the second bending composite section 51 and the second panel portion 20; the first folding receiving concave portion 42 and the second folding receiving concave portion 52 respectively form a first folding receiving groove and a second folding receiving groove to receive the stitched folding edge. Similarly, the flatness of the surface of the hollow building panel can be improved. At the same time, the first stitched folding edge 11 in the first unit member can be inserted between the first bending composite section 41 and the first folding receiving concave portion 42 of the second unit member; the second stitched folding edge 21 in the first unit member can be inserted between the second bending composite section 51 and the second folding receiving concave portion 52 of the second unit member; and the first stitched folding edge 11 in the first unit member is kept in close contact and fixed with the first bending composite section 41 and the first folding receiving concave portion 42 of the second unit member; the second stitched folding edge 21 in the first unit member is kept in close contact and fixed with the second bending composite section 51 and the second folding receiving concave portion 52 of the second unit member. In this way, the reliability of the stitched connection and fixation between the unit members can be improved, and the rigidity of the hollow building panel can be improved.

[0040] Referring again to Figure 1 , in an embodiment of the present invention, the first panel portion 10 and the second panel portion 20 are symmetrically arranged. In this way, the flatness of the hollow building panel can be ensured and skewing can be avoided. And the cross-sectional width W1 of the first panel portion 10 is 1.3 to 1.9 times the cross-sectional width W2 of the core board 30. In this way, the supporting effect of the panel portion on the core board 30 can be ensured, and thus the strength of the hollow building panel can be ensured. At the same time, the cross-sectional width W3 of both the first stitched folding edge 11 and the second stitched folding edge 21 is greater than one-tenth of the cross-sectional width W1 of the first panel portion 10, which can ensure a suitable connection dimension between the unit members, and thus ensure the reliability of the connection between the unit members in the hollow building panel.

[0041] Although the preferred embodiments of the present invention have been described in the above description, those skilled in the relevant technical field can understand that many changes or modifications can be made in the details of the design, construction or operation without departing from the scope required by the present invention.
