Abstract

The application provides a hollow double-layer plate, which comprises a connecting frame, an upper layer plate and a lower layer plate. The connecting frame is formed by connecting a plurality of frames with an arch-shaped cross section. Each frame has an upper slot and a lower slot which are spaced apart and have openings facing inwards, and an outer recess between the upper slot and the lower slot and having an opening facing outwards. The outer edge of the upper layer plate is inserted into the upper slot. The lower layer plate is spaced apart from the upper layer plate, and the outer edge of the lower layer plate is inserted into the lower slot. The upper layer plate and the lower layer plate are assembled by using the frames with an arch-shaped cross section, so that a hollow double-layer plate structure is formed, and the assembly is simple. The hollow structure of the double-layer plate has a good heat preservation and energy saving effect. Meanwhile, the frame with an arch-shaped cross section has a simple structure, high strength and low cost. The hollow layer between the upper layer plate and the lower layer plate does not need a whole layer of reinforcing support structure for support, and is suitable for a plate which needs to transmit light.

Description

Technical Field

[0001] This invention relates to the field of sheet materials, specifically to a hollow double-layer sheet material. Background Technology

[0002] Current methods for preparing insulation panels generally involve layering and bonding multiple panels together. In multi-layer composite panels, the appropriate panel is selected based on the required function; for example, when thermal insulation is needed in curtain wall products, the insulation panel is sandwiched in the middle. However, this approach undoubtedly increases cost and weight. CN217352982U discloses an installation structure for thermal insulation panels used in building decoration engineering, which includes a semi-hollow layer between the upper and lower panels. The semi-hollow layer has a wave-shaped reinforcing support structure to support the upper and lower panel structures. This approach also results in higher costs; furthermore, the entire reinforcing support structure is opaque and cannot be used on translucent panels. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a hollow double-layer sheet material.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0005] A hollow double-layer board includes a connecting frame, an upper plate, and a lower plate. The connecting frame is formed by splicing together multiple "bow"-shaped frames end to end. Each frame has an upper slot and a lower slot with inward openings, spaced apart vertically, and an outward-opening recess located between the upper and lower slots. The outer edge of the upper plate is inserted into the upper slot. The lower plate is spaced apart from the upper plate, and its outer edge is inserted into the lower slot.

[0006] Furthermore, adjacent frames are connected by angle irons; the angle irons have a first connecting rod and a second connecting rod arranged at an angle to each other, and the first connecting rod and the second connecting rod are respectively assembled into the outer recesses of two adjacent frames and fixedly connected.

[0007] Furthermore, a support beam is also fitted between the two oppositely arranged sidewalls of the connecting frame.

[0008] Furthermore, the support beam abuts against and is fixed to the side wall located between the upper and lower slots.

[0009] Furthermore, a connecting piece is formed on the end of the support beam, and corresponding connecting holes are provided on the connecting piece and the side wall of the frame. It also includes a screw locking member, which passes through the outer recess into the connecting hole of the connecting piece and the connecting hole of the side wall of the frame and is screwed and locked.

[0010] Furthermore, the supporting beam is a profile with a "bow" shaped cross-section.

[0011] Furthermore, the connecting frame is a quadrilateral frame formed by splicing together four borders with a "bow" shaped cross-section, and both the upper and lower plates are square plates.

[0012] Furthermore, of the upper and lower plates, one is a photovoltaic panel and the other is an explosion-proof glass panel.

[0013] Furthermore, of the upper and lower panels, one is a curtain wall panel and the other is a dry-hanging building panel.

[0014] The technical solution provided by this invention has the following beneficial effects:

[0015] The upper and lower panels are assembled using a bow-shaped frame to form a hollow double-layer panel structure, which is easy to assemble. The hollow structure of the double-layer panel provides excellent thermal insulation and energy saving. At the same time, the bow-shaped frame structure is simple, strong, and low in cost. Furthermore, the upper and lower panels are mainly fixed by the bow-shaped frame, achieving stable support. The hollow layer between the upper and lower panels does not require a full-layer reinforcing support structure, making it suitable for panels that require light transmission.

With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 7 As shown in the figure, this embodiment provides a hollow double-layer board, including a connecting frame 10, an upper plate 21, and a lower plate 22. Specifically, the connecting frame 10 is a quadrilateral frame formed by splicing together four "bow"-shaped frame edges 11 end to end, specifically a rectangular frame. Each frame edge 11 has an upper slot 111 and a lower slot 112 spaced apart vertically and opening inward, and an outer recess 113 located between the upper slot 111 and the lower slot 112 and opening outward.

[0027] Both the upper plate 21 and the lower plate 22 are square plates; more specifically, in this embodiment, one of the upper plate 21 and the lower plate 22 is a photovoltaic panel, and the other is an explosion-proof glass panel; for example, the upper plate 21 is an explosion-proof glass panel, and the lower plate 22 is a photovoltaic panel. Figure 3 , Figure 4 As shown, the outer edge of the upper plate 21 is inserted into the upper slot 111; the lower plate 22 is spaced apart from the upper plate 21, and the outer edge of the lower plate 22 is inserted into the lower slot 112.

[0028] The upper panel 21 and lower panel 22 are assembled using a bow-shaped frame 11, forming a hollow double-layer panel structure, which is easy to assemble. The hollow structure of the double-layer panel provides excellent thermal insulation and energy saving. Meanwhile, the bow-shaped frame 11 is simple in structure, strong, and low in cost. The upper panel 21 and lower panel 22 are mainly fixed by the bow-shaped frame 11, achieving stable support. The hollow layer between the upper panel 21 and lower panel 22 does not require a full-layer reinforcing support structure, making it suitable for panels that require light transmission. Sunlight can pass through the upper panel 21 (i.e., the explosion-proof glass panel) and the hollow structure to reach the lower panel 22 (i.e., the photovoltaic panel), achieving photovoltaic power generation. This is suitable for photovoltaic curtain walls, serving both thermal insulation and power generation functions.

[0029] Adjacent frame pieces 11 are connected by angle irons 12. Each angle iron 12 has a first connecting rod 121 and a second connecting rod 122 arranged at an angle to each other. Specifically, the angle iron 12 is L-shaped, meaning the first connecting rod 121 and the second connecting rod 122 are perpendicular to each other. The first connecting rod 121 and the second connecting rod 122 are respectively assembled and fixedly connected within the outer recesses 113 of two adjacent frame pieces 11, resulting in a sturdy and secure structure that is easy to assemble. Specifically, the angle iron 12 is connected to the frame piece 11 by screws 31. Furthermore, both the first connecting rod 121 and the second connecting rod 122 are located within the outer recesses 113 and do not protrude from the connecting frame 10, resulting in a simpler structure that does not affect the dimensions.

[0030] Specifically, the connecting frame 10 is a rectangular frame. The two side frames 11, which are the longer sides, are quite long, resulting in poor support for the upper plate 21 and lower plate 22 in the longitudinal direction. Therefore, in this embodiment, a support beam 13 is also installed between the two opposing side frames 11. Specifically, there are two support beams 13, arranged at intervals. The support beams 13 serve two purposes: firstly, they fix the two side frames 11, preventing them from bending and deforming, which could lead to detachment from the upper plate 21 or lower plate 22; secondly, they also support the upper plate 21 and lower plate 22, preventing the middle parts of the upper plate 21 and lower plate 22 from concave deformation. Simultaneously, the supporting beam 13 has a small shading area, minimizing its impact on light transmission. Of course, in other embodiments, when the size of the connecting frame 10 is small enough to provide sufficient strength, the auxiliary support of the support beam 13 may not be necessary.

[0031] The support beam 13 is a profile with an "arch"-shaped cross-section, providing good support strength. The support beam 13 abuts against and is fixed to the side wall 114 (i.e., the side wall 114 forming the outer recess 113) located between the upper slot 111 and the lower slot 112. Specifically, two connecting pieces 131 are formed at the ends of the support beam 13. Corresponding connecting holes are provided on the connecting pieces 131 and the side wall 114 of the frame 11: connecting hole 132 on the connecting piece 131 and connecting hole 101 on the side wall 114. A screw locking member 32 is also included. The screw locking member 32 passes through the outer recess 113 and is inserted into the connecting hole 132 of the connecting piece 131 and the connecting hole 101 of the side wall 114 of the frame 11, and is screwed in and locked. The connection structure is simple and robust. Simultaneously, the screw locking member 32 is also hidden within the outer recess 113 and does not protrude from the connecting frame 10.

[0032] Example 2

[0033] This embodiment provides a hollow double-layer panel, which is roughly the same as the structure in Embodiment 1. The difference is that the upper panel 21 and the lower panel 22 are of different types. One of the upper panel 21 (such as the upper panel 21) is a curtain wall panel, and the other (such as the lower panel 22) is a dry-hanging building panel. The dry-hanging building panel can be made of various conventional building materials such as ceramic tile panels, cement boards, and calcium silicate boards that can be dry-hanging and fixed.

[0034] Example 3

[0035] The hollow double-layer board provided in this embodiment is roughly the same as the structure in Embodiment 1. The difference is that in this embodiment, the connecting frame 10 is a hexagonal frame structure formed by splicing together six borders 11 with "bow" shaped cross sections. The upper plate 21 and the lower plate 22 are also hexagonal boards. Thus, after assembly, a hexagonal hollow double-layer board is formed.

[0036] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
