A high-strength, high-wave waterproof polycarbonate sheet with a sealed edge snap-fit ​​structure

Abstract

This utility model relates to the field of polycarbonate sheet technology, specifically to a high-strength, high-wave waterproof polycarbonate sheet sealing edge snap-fit ​​structure, comprising: at least two sheets whose ends are aligned and connected sequentially, each sheet having a first snap-fit ​​portion at one end and a second snap-fit ​​portion adapted to the first snap-fit ​​portion at the other end. Connection is achieved by snapping the first snap-fit ​​portion at one end of the sheet with the second snap-fit ​​portion at the other end of the sheet. This utility model sets an annular sealing structure on any end face between two adjacent sheets. When the first snap-fit ​​portion of one sheet is snapped with the second snap-fit ​​portion of the adjacent sheet, the pressure between the end faces of the two sheets causes the annular sealing structure to actively deform, eliminating micro-gaps caused by processing tolerances and thermal expansion and contraction. The annular sealing design achieves 360-degree full-circumference waterproofing.

Description

Technical Field

[0001] This utility model relates to the field of polycarbonate board technology, and in particular to a high-wave, high-strength, waterproof polycarbonate board sealing edge buckle structure. Background Technology

[0002] Polycarbonate sheets, especially high-strength polycarbonate sheets with high crest design, are widely used in open or semi-open environments such as building skylights, awnings, greenhouses, and industrial plant roofs and walls due to their excellent impact resistance, weather resistance, light transmission and lightweight properties. In such applications, the sheets usually need to be spliced ​​to cover a large area.

[0003] Currently, one of the mainstream methods for connecting the edges of adjacent polycarbonate sheets is through a snap-fit ​​structure. The common snap-fit ​​structure involves setting matching male and female snaps on the edges of the sheets. This mechanical snap-fit ​​method is easy to install, relatively firm, and can effectively limit the displacement of the sheets in the plane, meeting basic connection and fixing requirements.

[0004] However, existing snap-fit ​​connection structures of this type have a significant drawback:

[0005] After adjacent boards are fixed together by snap-fit, tiny gaps or gaps will inevitably exist at their joint interface. The problems caused by this defect are particularly prominent in outdoor application environments. When it rains, rainwater is easily seeped into the joint of the boards by the wind or flowing along the surface of the boards. The seeping water and impurities will accumulate inside the snap-fit ​​or between the joint surfaces of the boards, which not only affects the appearance, but may also breed mold and algae. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a high-wave, high-strength waterproof polycarbonate board sealing edge buckle structure to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides a high-strength, high-wave waterproof polycarbonate sheet sealing edge buckle structure, comprising:

[0008] At least two plates whose ends are aligned and connected in sequence, one end of the plate is provided with a first engaging part, and the other end of the plate is provided with a second engaging part adapted to the first engaging part. The connection is achieved by engaging the first engaging part at the end of one plate with the second engaging part at the end of the other plate.

[0009] An annular sealing structure is provided on the end face of the plate near the first engaging part and / or the second engaging part to surround the first engaging part and / or the second engaging part. When engaged, the end faces between adjacent plates apply pressure to the annular sealing structure to deform it and seal the gap between the end faces to achieve waterproofing.

[0010] As a preferred embodiment of the present invention, the first engaging part is a T-shaped block, and correspondingly, the second engaging part is a T-shaped groove that is adapted to the T-shaped block.

[0011] As a preferred embodiment of this utility model, the height of the T-block is less than the height of the corresponding end, and the bottom of the T-slot is closed and the top is open, so that the T-block can be inserted into the T-slot from the opening.

[0012] As a preferred embodiment of this utility model, the plate body is provided with a cover at its upper end near the T-shaped block, the cover completely covering the upper surface of the T-shaped block, and the plate body is provided with a corresponding clearance opening at its upper end near the T-shaped groove.

[0013] As a preferred technical solution of this utility model, the plate body has an installation groove on its end face near the T-groove, and the annular sealing structure is a strip-shaped sealing ring disposed in the installation groove.

[0014] As a preferred embodiment of this utility model, the plate body has a first positioning hole with a through T-shaped groove on the front side, and the T-shaped block has a second positioning hole corresponding to the first positioning hole. A positioning element for connecting the two is provided between the first positioning hole and the second positioning hole.

[0015] As a preferred embodiment of this utility model, the positioning element is a bolt.

[0016] As a preferred embodiment of this utility model, the bolt body is fitted with an annular sealing ring near the bolt cap.

[0017] The beneficial effects of this utility model are as follows: This utility model sets the annular sealing structure on any one end face between two adjacent plates. When the first engaging part of one plate is engaged with the second engaging part of the adjacent plate, the pressure on the end faces between the two plates causes the annular sealing structure to actively deform, eliminating micro-gaps caused by processing tolerances and thermal expansion and contraction. The annular sealing design achieves 360-degree full-circumference waterproofing, which is especially suitable for wind pressure and rainwater penetration in open-air environments. No additional caulking process is required, reducing on-site installation costs. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] like Figure 1As shown, a high-strength, waterproof polycarbonate sheet sealing edge snap-fit ​​structure includes: at least two plates 1 with their ends aligned and connected in sequence; one end of each plate 1 is provided with a first snap-fit ​​portion 2, and the other end of each plate 1 is provided with a second snap-fit ​​portion 3 adapted to the first snap-fit ​​portion 2; the connection is achieved by snapping the first snap-fit ​​portion 2 at one end of one plate 1 with the second snap-fit ​​portion 3 at the other end of the plate 1; and an annular sealing structure, which is provided on the end face of the plate 1 near the first snap-fit ​​portion 2 and / or the second snap-fit ​​portion 3 to surround the first snap-fit ​​portion 2 and / or the second snap-fit ​​portion 3. When snapped, pressure is applied to the end face between adjacent plates 1 to deform the annular sealing structure and seal the gap between the end faces to achieve waterproofing.

[0027] The above technical solution can seal the connection between the plates 1. In use, the annular sealing structure is set on any end face between two adjacent plates 1. When the first engaging part 2 of one plate 1 is engaged with the second engaging part 3 of the adjacent plate 1, the pressure between the end faces of the two plates 1 causes the annular sealing structure to deform actively, eliminating the micro gaps caused by processing tolerances and thermal expansion and contraction. The annular sealing design achieves 360-degree full-circumference waterproofing, which is especially suitable for wind pressure and rainwater penetration in open-air environments. No additional caulking process is required, reducing on-site installation costs.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the first engaging part 2 is a T-shaped block, and correspondingly, the second engaging part 3 is a T-shaped groove that is adapted to the T-shaped block;

[0029] The above technical solution can ensure that after the first engaging part 2 is engaged with the second engaging part 3, the two corresponding plates 1 will not be disconnected in the connection direction due to external force. The structure of the T-block and T-groove provides wind pressure resistance and mechanical strength. The height difference design reserves the compression space of the sealing structure, and the closed groove bottom blocks the longitudinal penetration path of water.

[0030] like Figure 3 As shown, in this embodiment, the height of the T-block is less than the height of the corresponding end, the bottom of the T-slot is closed and the top is open, so that the T-block can be inserted into the T-slot from the opening.

[0031] The above technical solution can ensure that after the T-block is inserted into the T-slot, the top and bottom ends of the two plates 1 are flush, ensuring that the surface of the plate is smooth and does not protrude.

[0032] like Figure 1 and Figure 3As shown, in this embodiment, the plate 1 is provided with a cover 8 at its upper end near the T-shaped block. The cover 8 completely covers the upper end surface of the T-shaped block. The plate 1 is provided with a clearance opening 9 corresponding to the cover 8 at its upper end near the T-shaped groove. The plate 1 is provided with an installation groove 10 on its end face near the T-shaped groove. The annular sealing structure is a strip sealing ring 11 provided in the installation groove 10.

[0033] The above technical solution can ensure that the mounting groove 10 accurately positions the strip sealing ring 11, prevent displacement during construction, ensure low-pressure sealing with interference fit design, and facilitate future maintenance with replaceable strip sealing ring 11.

[0034] like Figure 1 and Figure 4 As shown, in this embodiment, the plate 1 has a first positioning hole 4 that passes through the T-shaped groove on the front side, and the T-shaped block has a second positioning hole 5 corresponding to the first positioning hole 4. A positioning element 6 for connecting the two is provided between the first positioning hole 4 and the second positioning hole 5. Preferably, the positioning element 6 is a bolt, and the bolt body is fitted with an annular sealing ring 7 near the bolt cap.

[0035] The above technical solution can further improve the connection strength of the plates. After the T-block is inserted into the T-slot, the bolts can be screwed into the positioning holes on the surface of the T-block and the T-slot to prevent the T-block from accidentally falling off from the upper opening of the T-slot, thus enhancing the wind resistance. The annular sealing ring 7 blocks the water seepage channel between the first positioning hole 4 and the second positioning hole 5, further improving the waterproof effect.

[0036] In this embodiment, the material selection for the sheet material is preferably high molecular weight PC with a melt flow index (MFI) < 10 g / 10 min, a wave height design of ≥ 50 mm, and a wave crest angle that is trapezoidal or arc-shaped (not shown in the figure). The wall thickness at the wave trough is increased by 20-30%.

[0037] The above technical solution can make the plate have higher tensile strength, impact toughness and creep resistance. The high viscosity melt is more likely to maintain the stability of complex waveform structure and is less likely to collapse during cooling. In terms of waveform optimization, the compressive strength is increased by more than 30% compared with the triangular wave, and buckling deformation is suppressed.

[0038] Working principle: When in use, the strip sealing ring 11 is placed in the mounting groove 10 at one end of the plate 1. When connecting, the first engaging part 2 of one plate 1 is engaged with the second engaging part 3 of the adjacent plate 1 until the first engaging part 2 is inserted to the maximum depth in the second engaging part 3. The strip sealing ring 11 is actively deformed by the pressure of the end faces between the two plates 1 and the cover 8, eliminating the micro gaps caused by processing tolerances and thermal expansion and contraction. The annular sealing design achieves 360-degree full circumference waterproofing.

[0039] Then, the annular sealing ring 7 is fitted onto the positioning member 6. The positioning member 6 is screwed into the second positioning hole 5 and the first positioning hole 4 of the first engaging part 2 and the second engaging part 3. This can prevent the first engaging part 2 from accidentally falling off from the upper opening of the second engaging part 3, enhance the wind resistance, and block the water seepage channel between the first positioning hole 4 and the second positioning hole 5, further improving the waterproof effect.

[0040] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0041] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
