Technical Field

[0001] The invention relates to a building technology, in particular to a modular structure. Background Art

[0002] At present, there is a great demand for modular structures such as portable or mobile structures. The current modular structures usually include multiple prefabricated parts that can cooperate with each other to form vertical wall panels and flat wall panels that are basically horizontal. On site, multiple prefabricated parts are combined and fixed to form a building, house or other structure with a suitable space.

[0003] How to improve the efficiency of connection and fixation between prefabricated parts and ensure the reliability of connection and fixation between prefabricated parts is a technical problem that needs to be solved at present.

[0004] In addition, in the prior art, there is already a way to form a building using a hollow building panel. The hollow building panel usually has a hollow structure, which can greatly reduce the weight of the hollow building panel. The hollow building panel is usually formed by connecting a plurality of unit components. By changing the number of unit components, the hollow building panel can have a suitable area. The shape of the structure of the unit component not only affects the mechanical properties of the hollow building panel, but also affects the connection and fixing method between the unit components, thereby affecting the production efficiency of the hollow building panel.

[0005] Therefore, how to improve the production efficiency of hollow building panels while ensuring the mechanical properties of hollow building panels is another important problem that needs to be solved by those skilled in the art. Summary of the invention

[0006] To this end, the present invention provides a modular structure, the prefabricated parts of the vertical wall panels and the flat wall panels of the structure can be more conveniently positioned and fixed, and the reliability of the connection and fixation between the prefabricated parts can be improved.

[0007] The combined structure provided by the present invention comprises a vertical wall panel and a flat wall panel; the upper end and the lower end of the vertical wall panel are respectively fixed to a flat wall panel, and also comprises a Z-shaped connector; the Z-shaped connector comprises a flat connecting plate, a vertical connecting plate, a supporting plate and a limiting plate connected in sequence, and a limiting groove is formed between the vertical connecting plate, the supporting plate and the limiting plate; the flat connecting plate extends horizontally; the vertical connecting plate extends vertically downward; the supporting plate also extends horizontally, in the opposite direction of the extension direction of the flat connecting plate. The limiting plate extends vertically upward.

[0008] The end of the vertical wall panel is inserted into the limiting groove, the vertical connecting plate is located between the side wall surface of the flat wall panel and the inner wall surface of the vertical wall panel, and the flat connecting plate is fitted and positioned with the upper surface or the lower surface of the flat wall panel, thereby keeping the end of the vertical wall panel and the flat wall panel fixed.

[0009] In this way, the positioning between the vertical wall panel and the flat wall panel can be achieved through the limiting groove of the Z-shaped connector. At the same time, the vertical wall panel and the Z-shaped connector, combined with the larger area of ​​the flat wall panel, can ensure the relative positioning of the vertical wall panel and the flat wall panel, and ensure the reliability of the relative fixation between the two.

[0010] In a further technical solution, the outer edge of the limiting plate is inclined in a direction away from the vertical connecting plate, so that the end of the vertical wall panel can be easily inserted into the limiting groove, and rapid positioning can be achieved, thereby improving the assembly efficiency.

[0011] In a further technical solution, the flat connecting plate is fixed to the upper surface or lower surface of the flat wall panel by fasteners; the limiting plate can also be fixed to the surface of the vertical wall panel by fasteners, thereby improving the reliability of fixing the vertical wall panel to the flat wall panel.

[0012] A further technical solution also includes an L-shaped connector formed by two connecting side panels; one connecting side panel of the L-shaped connector is attached to and fixed to the flat connecting plate, and the other connecting side panel is attached to and fixed to the surface of the vertical wall panel, thereby keeping the vertical wall panel and the flat wall panel fixed, thereby enhancing the reliability of the fixation of the two.

[0013] In a further technical solution, at least a portion of the vertical wall panel and the flat wall panel is a hollow building panel, and the central cavity building panel includes a plurality of sequentially arranged unit components, edge unit components and blocking components; the unit component is formed by bending a complete plate, and may include a first panel portion, a second panel portion and a core plate;

[0015] The first connecting folded edge portion and the second connecting folded edge portion of the unit component may respectively include a first bending compound section and a first bending compound section inclined outward; and the first bending compound section and the first bending compound section may respectively correspond to the first sewing flange and the second sewing flange to facilitate the sewing and fixation between the unit components.

[0016] The above-mentioned unit components formed by bending can be sequentially arranged in the cross-sectional direction, and the first bending compound section in the first unit component is inserted between the first stitching flange and the first panel part of the second unit component; the second bending compound section in the first unit component is inserted between the second stitching flange and the second panel part of the second unit component; and the first bending compound section of the first unit component is kept in close contact with the first stitching flange and the first panel part of the second unit component, and the second bending compound section in the first unit component is kept in close contact with the second stitching flange and the second panel part of the second unit component, so that the adjacent unit components can be stitched and kept fixed, and several unit components are sequentially connected and fixed in the same way to form a hollow building panel of appropriate size. The first bending compound section in the first unit component cooperates with the first stitching flange of the second unit component to conveniently form a hollow building panel; at the same time, the unit components are stitched and fixed by the first bending compound section in the first unit component and the first stitching flange of the second unit component, and then the first panel part and the second panel part are connected in combination with the core plate, so that the production efficiency of the hollow building panel can be improved while ensuring the mechanical properties of the hollow building panel.

[0017] 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, the first panel part and the second panel part can be in the same relative position with the core plate before and after the hollow building panel is stitched, which reduces the stress of the hollow building panel after stitching, reduces the deformation of the hollow building panel, and improves the stability of the performance of the hollow building panel structure.

[0018] In a further optional technical solution, when forming the unit component, the extension direction of the core plate is perpendicular to the extension direction of the first panel portion, so that the supporting function of the core plate can be fully utilized to ensure the rigidity and stability of the hollow building panel in the thickness direction.

[0019] In a further reliable technical solution, when forming a unit component, the first panel part and the second panel part are respectively extended to both sides in an inclined manner. In this way, when sewing the unit component, the conical structure formed by the first panel part and the second panel part can be used to facilitate the joining between the unit components, thereby facilitating the sewing and fixing, thereby improving the production efficiency of the hollow building panel and reducing the cost of the hollow building panel.

[0020] In a further preferred technical solution, the first connecting folding edge portion and the second connecting folding edge portion further include a first folding accommodating inner recess and a second folding accommodating inner recess, respectively; the first folding accommodating inner recess is connected between the first bending compound section and the first panel portion, and the second folding accommodating inner recess is connected between the second bending compound section and the second panel portion; the first folding accommodating inner recess and the second folding accommodating inner recess form a first folding accommodating groove and a second folding accommodating groove, respectively, and accommodate the stitched folding edge; it is further preferred that the depth of the first folding accommodating groove and the second folding accommodating groove are not less than 4 times the thickness of the sheet material forming the unit component. In this way, the stitched folding edge can be located within the side 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 performance of the hollow building panel.

[0021] In an optional technical solution, the first panel part and the second panel part are symmetrically arranged, so as to ensure that the hollow building panel is flat and avoid deflection.

[0022] In an optional technical solution, the cross-sectional width of the first panel portion is 1.3 to 1.9 times the cross-sectional width ratio of the core panel. In this way, the supporting function of the panel portion of the core panel can be ensured, thereby ensuring the strength of the hollow building panel. At the same time, the cross-sectional widths of the first stitched flange and the second stitched flange are both greater than one tenth of the cross-sectional width of the first panel portion, which can ensure that the unit components have a suitable connection size, thereby ensuring the reliability of the connection between the unit components in the hollow building panel.

[0023] In a further preferred technical solution, the first stitched flange in the first unit component is inserted between the first bent composite section and the first folded accommodating inner recess of the second unit component; the second stitched flange in the first unit component is inserted between the second bent composite section and the second folded accommodating inner recess of the second unit component; and the first stitched flange in the first unit component is kept in close contact with the first bent composite section and the first folded accommodating inner recess of the second unit component; the second stitched flange in the first unit component is kept in close contact with the second bent composite section and the second folded accommodating inner recess of the second unit component.

[0024] In a further technical solution, the hollow building panel also includes an edge unit component and a blocking structure; the edge unit component is formed by bending a complete plate, including a first edge panel part, a second edge panel part and an edge core plate; the two ends of the edge core plate are respectively connected to the inner ends of the first edge panel part and the second edge panel part through a first edge connecting folding part and a second edge connecting folding part; the first edge bending compound section in the edge unit component is inserted between the first stitched flange of the outermost unit component and the first panel part; the second edge bending compound section in the edge unit component is inserted between the second stitched flange of the outermost unit component and the second panel part; and the first edge bending compound section of the edge unit component is kept in close contact with the first stitched flange and the first panel part of the outermost unit component, and the second edge bending compound section of the edge unit component is kept in close contact with the second stitched flange and the second panel part of the outermost unit component;

[0025] The two sides of the blocking member are respectively connected to the first edge panel part and the second edge panel part to block the outer edge opening of the edge unit member. The edge unit member and the blocking member can block the opening of the hollow building panel, which can ensure the strength and rigidity of the hollow building panel on the one hand and improve the safety of the hollow building panel on the other hand.

[0041] The specific embodiments provided by the present invention are described below. The modular structure is described first, and then the unit components of the hollow building panel and the structure of the hollow building panel formed by the unit components are explained.

[0042] Those skilled in the art can understand that in this patent, the unit component is a long strip component, and its main improved structure is reflected in the cross-sectional structure. Therefore, for the convenience of description and understanding, the directional words in this document are mainly determined based on the cross-sectional views shown in the corresponding drawings; similarly, for the convenience of description and understanding, and to save space, this section explains the hollow building panel while describing the unit component of the hollow building panel.

[0043] Please refer to Figures 1 to 3 , Figure 1A longitudinal cross-sectional structural diagram of the modular structure provided by the present invention, which shows the arrangement and connection structure of the vertical wall panel 100 and the horizontal wall panel 200; Figure 2 for Figure 1 Enlarged view of part B; Figure 3 for Figure 1 The cross-sectional structure diagram of the Z-shaped connector 400. The combined structure may include a vertical wall panel 100 and a flat wall panel 200. The vertical wall panel 100 is a panel arranged vertically, and may include a plurality of vertical wall panels. The plurality of vertical wall panels 100 may be properly arranged to form a proper space and realize the separation between indoor and outdoor. The flat wall panel 200 includes a top flat wall panel to serve as the top plate of the structure; and may also include a bottom flat wall panel to serve as the floor of the structure.

[0044] like Figure 1 As shown, the upper end and the lower end of the vertical wall panel 100 are respectively fixed to a flat wall panel 200. In this embodiment, the side wall surface of the flat wall panel 200 is opposite to the inner wall surface of the vertical wall panel 100, that is, the side wall surface of the top flat wall panel 200 is opposite to the inner wall surface above the vertical wall panel 100, and the side wall surface of the bottom flat wall panel 200 is opposite to the inner wall surface below the vertical wall panel 100.

[0045] In addition, a Z-shaped connector 400 is also included; the Z-shaped connector 400 includes a flat connecting plate 410, a vertical connecting plate 420, a supporting plate 430 and a limiting plate 440 connected in sequence, and a limiting groove 401 is formed between the vertical connecting plate 420, the supporting plate 430 and the limiting plate 440.

[0046] During assembly, the end of the vertical wall panel 100 is inserted into the limiting groove 401, the vertical connecting plate 420 is located between the side wall surface of the flat wall panel 200 and the inner wall surface of the vertical wall panel 100, and the flat connecting plate 410 is fitted and positioned with the upper surface or the lower surface of the flat wall panel 200, thereby keeping the end of the vertical wall panel 100 and the flat wall panel 200 fixed.

[0047] Figure 2 The diagram shows the connection structure between the side wall surface of the flat wall panel 200 and the lower part of the vertical wall panel 100. It can be determined from the figure that in this case, the lower end of the vertical wall panel 100 is inserted into the limiting groove 401, and the flat connecting plate 410 of the Z-shaped connector 400 is supported on the upper surface of the bottom flat wall panel 200, which can ensure the reliability of the connection between the flat wall panel 200 and the vertical wall panel 100 on the basis of achieving accurate positioning between the flat wall panel 200 and the vertical wall panel 100.

[0048] At the same time, referring to 1, when the side wall surface of the flat wall panel 200 is connected to the upper part of the vertical wall panel 100, the upper end of the vertical wall panel 100 is inserted into the limiting groove 401, and the flat connecting plate 410 of the Z-shaped connector 400 is supported on the lower surface of the top flat wall panel 200. The limiting groove 401 covers the upper end of the vertical wall panel 100 at the same time. On the one hand, the vertical wall panel 100 can be positioned, and at the same time, the flat wall panel 200 and the vertical wall panel 100 can be accurately positioned to ensure the reliability of the connection between the two. In short, the positioning between the vertical wall panel 100 and the flat wall panel 200 can be achieved through the limiting groove 401 of the Z-shaped connector 400. At the same time, the vertical wall panel 100 and the flat wall panel 200 can be relatively positioned by using the vertical wall panel 100 and the Z-shaped connector 400, combined with the characteristics of the larger area of ​​the flat wall panel 200, and the relative positioning of the vertical wall panel 100 and the flat wall panel 200 can be ensured, and the reliability of the relative fixation between the two can be ensured.

[0049] Refer to Figure 3 , the outer edge of the limiting plate 440 is inclined in a direction away from the vertical connecting plate 420. In this way, the end of the vertical wall panel 100 can be easily inserted into the limiting groove 401, and rapid positioning can be achieved, thereby improving the assembly efficiency.

[0050] It can be understood that the flat connecting plate 410 is fixed to the upper surface or the lower surface of the flat wall panel 200 by fasteners, and the limiting plate 440 can also be fixed to the surface of the vertical wall panel 100 by fasteners, thereby improving the reliability of the fixing of the vertical wall panel 100 and the flat wall panel 200.

[0051] like Figure 2 As shown, the modular structure also includes an L-shaped connector 500 formed by two connecting side panels; one connecting side panel of the L-shaped connector 500 is attached to and fixed to the flat connecting plate 410, and the other connecting side panel is attached to and fixed to the surface of the vertical wall panel 100, thereby keeping the vertical wall panel 100 and the horizontal wall panel 200 fixed, thereby enhancing the reliability of the fixation of the two.

[0052] Please refer to Figure 4 , Figure 4 Shows Figure 1 The figure is a partial transverse cross-sectional structural diagram of the combined structure provided by the present invention, which shows the connection structure of two vertical wall panels 100. As shown in the figure, the two vertical wall panels 100 are perpendicular to each other and are connected by two L-shaped connectors 500a and 500b. The L-shaped connector 500a is smaller in size and located on the inner side, and its two connecting side panels are respectively attached to and fixed on the inner surfaces of the two vertical wall panels 100. The L-shaped connector 500b is larger in size and located on the outer side, and its two connecting side panels are respectively attached to and fixed on the outer surfaces of the two vertical wall panels 100.

[0053] The vertical wall panel 100 and the flat wall panel 200 may be existing hollow building panels, or may be partially hollow building panels.

[0054] The following is an explanation of the structure of the unit components of the hollow building panel provided by the present invention. Figure 5 , Figure 5 The present invention provides a cross-sectional structure diagram of a unit component of a hollow building panel. The unit component is a long strip, which is formed by bending a plate of 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 component lies in the cross-sectional structure, which includes a first panel part 10, a second panel part 20 and a core plate 30.

[0055] The two ends of the core plate 30 are connected to the inner ends of the first panel part 10 and the second panel part 20 through the first connecting folding part 40 and the second connecting folding part 50. The connecting folding part is formed by composite plates, and the first connecting folding part 40 and the second connecting folding part 50 respectively include a first bending composite section 41 and a first bending composite section 51 inclined outward.

[0056] The inner end of the first panel portion 10 and the outer end of the second panel portion 20 respectively form a first sewing cuff 11 and a second sewing cuff 21 that are bent inward and inward to form a hook shape.

[0057] The first bending composite section 41 and the first bending composite section 51 correspond to the first sewing flange 11 and the second sewing flange 21 respectively, so that the unit components overlap with each other, thereby facilitating the sewing and fixing of the unit components.

[0058] Please refer to Figure 6 and Figure 7 , Figure 6 For two adjacent Figure 5 The corresponding diagram of the unit components shown in the figure, Figure 7 The figure shows the interlaced state of the bent composite sections and the sewn flanges of two adjacent unit components. It can be determined that the above-mentioned unit components formed by bending can be arranged sequentially in the cross-sectional direction, and the first bent composite section 41 in the first unit component is inserted between the first sewn flange 11 of the second unit component and the first panel part 10; the second bent composite section 51 in the first unit component is inserted between the second sewn flange 21 of the second unit component and the second panel part 20.

[0059] Refer to Figure 8 and Fig. 9 , Figure 8 The structure of the two adjacent unit components with bent composite sections and sewn flanges is shown. Fig. 9 for Figure 8The enlarged structural diagram of part A in the middle. The first bending compound section 41 of the first unit component is kept in close contact with the first stitching flange 11 and the first panel part 10 of the second unit component, and the second bending compound section 51 in the first unit component is kept in close contact with the second stitching flange 21 and the second panel part 20 of the second unit component, so that the adjacent unit components can be stitched and kept fixed. Several unit components are connected and fixed in sequence in the same way to form a hollow building panel of appropriate size. The first bending compound section 41 in the first unit component cooperates with the first stitching flange 11 of the second unit component to conveniently form a hollow building panel; at the same time, the unit components are stitched and fixed by the first bending compound section 41 in the first unit component and the first stitching flange 11 of the second unit component, and then the first panel part 10 and the second panel part 20 are connected in combination with the core plate 30, which can improve the production efficiency of the hollow building panel while ensuring the mechanical properties of the hollow building panel.

[0060] In this embodiment, when bending to form a unit component, the extension direction of the first panel part 10 and the second panel part 20 can be kept parallel. Before sewing 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. In this way, the relative positions of the first panel part 10, the second panel part 20 and the core plate 30 can be the same before and after the hollow building panel is sewn, which reduces the stress of the hollow building panel after sew, reduces the deformation of the hollow building panel, and improves the stability of the performance of the hollow building panel mechanism. Of course, when bending to form a unit component, the first panel part 10 and the second panel part 20 can also be extended to both sides. In this way, when sewing the unit component, 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, thereby providing convenience for sewing and fixing, which can improve the production efficiency of the hollow building panel and reduce the cost of the hollow building panel.

[0061] In this embodiment, the extension direction of the core plate 30 is perpendicular to the extension direction of the first panel part 10. In this way, the supporting function of the core plate 30 can be fully utilized 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 plate 30 can also be relatively inclined to the extension direction of the first panel part 10 to have higher strength or rigidity in certain specific directions.

[0062] Please refer to Figures 5 to 9In this embodiment, the first connecting folding edge portion 40 and the second connecting folding edge portion 50 further include a first folding accommodating inner recess 42 and a second folding accommodating inner recess 52 respectively; the first folding accommodating inner recess 42 is connected between the first bending compound section 41 and the first panel section 10, and the second folding accommodating inner recess 52 is connected between the second bending compound section 51 and the second panel section 20; the first folding accommodating inner recess 42 and the second folding accommodating inner recess 52 respectively form a first folding accommodating groove and a second folding accommodating groove to accommodate the stitched folding edge; preferably, the depth of the first folding accommodating groove and the second folding accommodating groove is not less than 4 times the thickness of the sheet material forming the unit component. In this way, the stitched folding edge can be located inside the side of the first panel section 10 and the second panel section 20, thereby ensuring the flatness of the surface of the hollow building panel and improving the performance of the hollow building panel.

[0063] As described above, the above-mentioned unit components are sequentially arranged and sewed together to form the hollow building panel provided by the present invention. Fig.10 and Fig.11 , Fig.10 Provide an overall screenshot of the hollow building panel for the present invention, Fig.11The present invention provides a side view of a hollow building panel. In the hollow building panel, the first bent compound section 41 in the first unit component is inserted between the first stitched flange 11 of the second unit component and the first panel portion 10; the second bent compound section 51 in the first unit component is inserted between the second stitched flange 21 of the second unit component and the second panel portion 20; and the first bent compound section 41 of the first unit component is kept in close contact with the first stitched flange 11 of the second unit component and the first panel portion 10, and the second bent compound section 51 in the first unit component is kept in close contact with the second stitched flange 21 of the second unit component and the second panel portion 20. The hollow building panel is formed by using the unit component, which can produce corresponding technical effects. As described above, in the hollow building panel, the first connecting folding edge portion 40 and the second connecting folding edge portion 50 can further include a first folding accommodating inner recess 42 and a second folding accommodating inner recess 52 respectively; the first folding accommodating inner recess 42 connects the first bending compound section 41 and the first panel section 10, and the second folding accommodating inner recess 52 connects the second bending compound section 51 and the second panel section 20; the first folding accommodating inner recess 42 and the second folding accommodating inner recess 52 respectively form a first folding accommodating groove and a second folding accommodating groove to accommodate the stitching folding edge. The flatness of the surface of the hollow building panel can also be improved. At the same time, the first stitched flange 11 in the first unit component can be inserted between the first bending compound section 41 and the first folding accommodating inner recess 42 of the second unit component; the second stitched flange 21 in the first unit component can be inserted between the second bending compound section 51 and the second folding accommodating inner recess 52 of the second unit component; and the first stitched flange 11 in the first unit component is kept in close contact with the first bending compound section 41 and the first folding accommodating inner recess 42 of the second unit component; the second stitched flange 21 in the first unit component is kept in close contact with the second bending compound section 51 and the second folding accommodating inner recess 52 of the second unit component. In this way, the reliability of stitching connection and fixation between unit components can be improved, and the rigidity of the hollow building panel can be improved.

[0064] Please refer to Fig.12 , Fig.12The present invention provides a cross-sectional structural diagram of a hollow building panel, illustrating an edge blocking structural diagram of the hollow building panel; in the figure, dotted lines illustrate unit components, and solid lines illustrate edge unit components and blocking components. The hollow building panel also includes an edge unit component and a blocking component 60; the edge unit component is formed by bending a complete plate, including a first edge panel part 1a, a second edge panel part 2a and an edge core plate 3a; the two ends of the edge core plate 3a are respectively connected to the inner end of the first edge panel part 1a and the inner end of the second edge panel part 2a through a first edge connecting folding part 41a and a second edge connecting folding part 51a; the first edge bending compound section 41a in the edge unit component is inserted between the first stitching flange 11 of the outermost unit component and the first panel part 10; the second edge bending compound section 51a in the edge unit component is inserted between the second stitching flange 21 of the outermost unit component and the second panel part 20; and the first edge bending compound section 41a of the edge unit component is kept in close contact with the first stitching flange 11 and the first panel part 10 of the outermost unit component, and the second edge bending compound section 51a of the edge unit component is kept in close contact with the second stitching flange 21 and the second panel part 20 of the outermost unit component;

[0065] The two sides of the blocking member 60 are respectively connected to the first edge panel part 1a and the second edge panel part 2a to block the outer opening of the edge unit member. The edge unit member and the blocking member 60 can block the opening of the hollow building panel, which can ensure the strength and rigidity of the hollow building panel on the one hand and improve the safety of the hollow building panel on the other hand.

[0066] In this embodiment, except that the first sewing flange 11 and the second sewing flange 21 are not formed, the edge unit component structure and shape can be the same as other unit components to facilitate the sealing of the opening edge of the hollow building panel. A folded accommodating inner concave portion and other structures can also be formed, which will not be described in detail here.

[0067] In the embodiment, the first edge panel portion 1a and the second edge panel portion 2a can be extended in parallel, and the outer ends of the first edge panel portion 1a and the second edge panel portion 2a can be kept flush with the outer surface of the blocking member 60 to ensure the flatness of the overall profile of the hollow building panel. The two sides of the blocking member 60 can form right-angle flanges 61, and the two right-angle flanges 61 are respectively attached to and fixed to the inner surfaces of the first edge panel portion 1a and the second edge panel portion 2a. In this way, the strength and rigidity of the hollow building panel can be improved.

[0068] Refer to Figure 5In one embodiment of the present invention, the first panel portion 10 and the second panel portion 20 are symmetrically arranged. This ensures that the hollow building panel is flat and avoids deflection. 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 panel 30. This ensures the supporting function of the panel portion of the core panel 30, thereby ensuring the strength of the hollow building panel. At the same time, the cross-sectional width W3 of the first stitched flange 11 and the second stitched flange 21 are both greater than one tenth of the cross-sectional width W1 of the first panel portion 10, thereby ensuring that the unit components have a suitable connection size, thereby ensuring the reliability of the connection between the unit components in the hollow building panel.

[0069] Although preferred embodiments of the present invention have been described in the foregoing description, those skilled in the relevant art will appreciate that many changes or modifications may be made in the details of design, construction or operation without departing from the scope of the present invention.
