Description

Technical Field

[0001] This utility model relates to the technical field of installation structure of polycarbonate sheets, specifically a waterproof installation structure for impact-resistant polycarbonate sheets. Background Technology

[0002] Polycarbonate sheets are widely used in outdoor settings due to their excellent impact resistance, lightweight properties, and good light transmission. They are especially often used as sunshades to provide sun protection for building facades, terraces, parking lots, and other areas.

[0003] When installing polycarbonate sheets, a metal frame must first be erected, and then the polycarbonate sheets are fixed to the frame one by one with screws. At the overlap between two adjacent polycarbonate sheets, elastic sealing strips are first filled, and then glass glue or special weather-resistant sealant is applied to the outside of the sealing strips or the screw heads to seal the gap between the two adjacent polycarbonate sheets and achieve a waterproof effect.

[0004] The installation process is complex, and the sealing strips are exposed to strong ultraviolet radiation for extended periods, causing them to age rapidly. Aged sealing strips lose their elasticity and cannot tightly seal the gaps between adjacent polycarbonate panels. As a result, rainwater can seep in directly through these gaps, affecting the usability of the shaded area. Utility Model Content

[0005] To address the aforementioned shortcomings, this invention proposes a waterproof installation structure for impact-resistant polycarbonate sheets. The insertion of the polycarbonate sheet into the receiving groove directly triggers the adhesive extrusion assembly, eliminating the need for additional sealing strips. The adhesive is located inside the splicing components, effectively avoiding direct sunlight and delaying adhesive aging. This solves the problems of complex installation procedures for traditional polycarbonate sheets and the rapid aging of adhesive strips due to prolonged exposure to strong ultraviolet radiation.

[0006] To achieve this objective, the present invention adopts the following technical solution: A waterproof installation structure for impact-resistant polycarbonate sheets includes polycarbonate sheets and splicing components, wherein two adjacent polycarbonate sheets are spliced ​​together by the splicing components; Both sides of the splicing component are provided with horizontally open receiving grooves. An extrusion assembly is provided in the receiving groove. The glue outlet of the extrusion assembly is located on the top side wall and the bottom side wall of the receiving groove. The extrusion assembly is used to extrude glue outward. When the polycarbonate sheet is horizontally inserted into the receiving groove, the polycarbonate sheet presses against the extrusion assembly, and the extrusion assembly squeezes out adhesive, thus bonding the polycarbonate sheet to the splicing component.

[0007] The receiving tank is provided with two rows of the extrusion assemblies, and multiple extrusion assemblies in the same row are arranged side by side. Each extrusion assembly includes a glue storage pressure bladder, the inner wall of which is fixedly connected to the inner side wall of the receiving tank. The glue storage pressure bladder is provided with a glue outlet pipe, the output end of which is located at the top of the receiving tank is located at the top side wall of the receiving tank, and the output end of which is located at the bottom of the receiving tank is located at the bottom side wall of the receiving tank.

[0008] A one-way valve is installed at the output end of the dispensing pipe.

[0009] The inner wall of the splicing component has two rows of channel groups, each channel group having multiple channels arranged side by side. The first end of each channel is located on the inner side wall of the receiving groove. The end of the channel located at the top is located on the top side wall of the receiving groove, and the end of the channel located at the bottom is located on the bottom side wall of the receiving groove. The glue dispensing pipe corresponds to each channel, and the output end of the glue dispensing pipe passes through the channel and is located on the top or bottom side wall of the receiving groove.

[0010] An aluminum foil sealing film is provided on the outside of the one-way valve.

[0011] The inner layer of the gel storage pressure bladder is an aluminum foil-PE composite film, and the outer layer of the gel storage pressure bladder is a high-elasticity silicone sleeve.

[0012] The distance between the one-way valve and the opening of the receiving groove is less than the distance between the one-way valve and the inner wall of the receiving groove.

[0013] The technical solution of this utility model can include the following beneficial effects: 1. The insertion of the polycarbonate sheet into the receiving groove directly triggers the adhesive extrusion assembly, eliminating the need for additional sealing strips during installation. The adhesive is located inside the splicing components, effectively avoiding direct sunlight and delaying its aging. This solves the problems of complex installation procedures for traditional polycarbonate sheets and the rapid aging of adhesive strips due to prolonged exposure to strong ultraviolet light.

[0014] 2. When the polycarbonate sheet is inserted into and presses against multiple adhesive storage pressure bladders, a large amount of adhesive can quickly and completely cover the contact area between the polycarbonate sheet and the splicing parts, avoiding the possibility of insufficient adhesive or blind spots in some areas that may occur in a single-row design. This significantly improves the integrity and uniformity of the sealing layer and further enhances the waterproof performance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following is combined with Figures 1 to 3 This invention describes a waterproof installation structure for an impact-resistant polycarbonate sheet according to an embodiment of the present invention.

[0021] A waterproof installation structure for impact-resistant polycarbonate sheets includes a polycarbonate sheet 1 and a splicing component 2, wherein two adjacent polycarbonate sheets 1 are spliced ​​together by the splicing component 2; Both sides of the splicing component 2 are provided with horizontally open receiving grooves 11. An extrusion assembly 3 is provided in the receiving groove 11. The glue outlet of the extrusion assembly 3 is provided on the top side wall 111 and the bottom side wall 112 of the receiving groove 11. The extrusion assembly 3 is used to extrude glue outward. When the polycarbonate sheet 1 is horizontally inserted into the receiving groove 11, the polycarbonate sheet 1 presses against the extrusion assembly 3, the extrusion assembly 3 extrudes glue outward, and the polycarbonate sheet 1 is bonded to the splicing piece 2.

[0022] When the polycarbonate sheet 1 is horizontally inserted into the receiving groove 11, the end of the polycarbonate sheet 1 presses against the extrusion assembly 3, causing the glue to be squeezed out from the glue outlets provided on the top side wall 111 and bottom side wall 112 of the receiving groove 11. This can accurately fill the gap between the polycarbonate sheet 1 and the splicing piece 2, so that rainwater cannot flow from the gap between two adjacent polycarbonate sheets 1.

[0023] The insertion of the polycarbonate sheet 1 into the receiving groove 11 directly triggers the adhesive extrusion assembly 3 to dispense adhesive, eliminating the need for additional sealing strips during installation. Because the adhesive is located inside the splicing component 2, it effectively avoids direct sunlight, significantly delaying adhesive aging. This solves the problems of complex installation procedures for traditional polycarbonate sheets and the rapid aging of adhesive strips due to prolonged exposure to strong ultraviolet radiation. Since the polycarbonate sheet 1 and the splicing component 2 are tightly bonded together with adhesive, upon impact, the impact force can be more evenly transmitted to adjacent polycarbonate sheets 1 through the splicing component 2, dispersing localized stress and reducing damage to the polycarbonate sheet 1 caused by concentrated stress. This better utilizes its impact resistance and extends its service life.

[0024] It is worth noting that workers can specifically select high-temperature resistant, fast-drying sealants as filler adhesives within the extruded components. These types of adhesives can reach initial curing strength within a short time after extrusion (usually a few minutes to tens of minutes), forming sufficient bonding force to further ensure that the polycarbonate sheet will not shift in the short term.

[0025] Even adhesives with long curing times will quickly develop a certain initial tack when they come into contact with the surfaces of polycarbonate sheet 1 and splice 2 after being extruded. This tack originates from the intermolecular forces between the adhesive and the contact surface. Although the strength is much lower than after full curing, it is sufficient to bond polycarbonate sheet 1 and splice 2 at the microscopic level, preventing relative sliding between the two.

[0026] Furthermore, there is a precise dimensional match between the receiving groove 11 of the splicing component 2 and the polycarbonate sheet 1. After the polycarbonate sheet is inserted into the receiving groove 11, the side wall of the receiving groove 11 will mechanically limit the polycarbonate sheet 1, restricting its large displacement in the horizontal and vertical directions. Therefore, regardless of the type of high-temperature resistant waterproof adhesive chosen, the polycarbonate sheet 1 and the splicing component 2 will not show any significant loosening after being spliced ​​together.

[0027] The receiving groove 11 is provided with two rows of the extrusion assembly 3, and multiple extrusion assemblies 3 in the same row are arranged side by side. The extrusion assembly 3 includes an adhesive storage pressure bladder 31. The inner wall of the adhesive storage pressure bladder 31 is fixedly connected to the inner side wall 113 of the receiving groove 11. The adhesive storage pressure bladder 31 is provided with an adhesive outlet pipe 32. The output end of the adhesive outlet pipe 32 located at the top is located on the top side wall 111 of the receiving groove 11, and the output end of the adhesive outlet pipe 32 located at the bottom is located on the bottom side wall 112 of the receiving groove 11.

[0028] When a single pressure bladder 31 is squeezed, the internal pressure transmission to the top and bottom is prone to deviation due to uneven deformation of the bladder, resulting in different discharge volumes at the top and bottom of the receiving tank 11.

[0029] This application features two rows of adhesive-storing pressure bladders 31, with multiple pressure bladders 31 arranged side-by-side in each row. This creates denser and more uniform adhesive dispensing points on the top sidewall 111 and bottom sidewall 112 of the receiving groove 11. When the polycarbonate sheet 1 is inserted into and presses against the multiple pressure bladders 31, a large amount of adhesive can quickly and completely cover the contact area between the polycarbonate sheet 1 and the splice 2, avoiding insufficient adhesive or blind spots that may occur with a single-row design. This significantly improves the integrity and uniformity of the sealing layer and further enhances the waterproof performance.

[0030] In addition, if a single glue storage pressure bladder 31 experiences an abnormal glue dispensing situation, the other glue storage pressure bladders 31 can still dispense glue normally, further ensuring the stability and reliability of the glue volume at the top and bottom.

[0031] A one-way valve 33 is provided at the output end of the glue dispensing pipe 32.

[0032] It should be noted that the one-way valve 33 is preferably a duckbill type one-way valve. The duckbill type one-way valve only allows the glue to be squeezed out from the glue outlet pipe 32, which can effectively prevent external rainwater, dust and other impurities from entering the glue storage pressure bladder 31 and contaminating the glue. At the same time, it avoids the backflow of the squeezed glue due to pressure changes, ensuring the continuity and stability of the glue's effect and improving the utilization efficiency of the glue.

[0033] The duckbill-type one-way valve 33 is closed when not under pressure, preventing the adhesive in the pressure bladder 31 from accidentally leaking out and causing waste and contamination when not in use. When the polycarbonate sheet 1 presses against the pressure bladder 31, increasing the internal pressure, the one-way valve 33 opens, allowing the adhesive to be squeezed out smoothly. The squeezed adhesive, under the action of the one-way valve 33, can fill the gaps more tightly. Combined with the uniform dispensing of adhesive from multiple pressure bladders 31, the resulting sealing layer is more airtight and reliable, further improving the overall structure's waterproof and moisture-proof capabilities.

[0034] The inner wall of the splicing component 2 is provided with two rows of channel groups. Each channel group has multiple channels arranged side by side. The first end of each channel is located on the inner side wall 113 of the receiving groove 11. The end of the channel located at the top is located on the top side wall 111 of the receiving groove 11, and the end of the channel located at the bottom is located on the bottom side wall 112 of the receiving groove 11. The glue dispensing pipe 32 corresponds to each channel. The output end of the glue dispensing pipe 32 passes through the channel and is located on the top side wall 111 or the bottom side wall 112 of the receiving groove 11.

[0035] The channel on the inner wall of the splice 2 provides a fixed guide path for the glue dispensing pipe 32, preventing the glue dispensing pipe 32 from shifting or bending during the process of the glue storage pressure bladder 31 being pressed or the polycarbonate sheet 1 being inserted, and ensuring that the glue can be stably delivered to the top side wall 111 or bottom side wall 112 of the receiving tank 11 along the preset trajectory.

[0036] An aluminum foil sealing film is provided on the outside of the one-way valve 33.

[0037] The aluminum foil sealing film forms an additional sealing barrier for the adhesive storage pressure bladder 31 and the one-way valve 33 during storage and transportation of the splice 2. This further prevents air from entering the adhesive storage pressure bladder 31 through the one-way valve 33, which could cause the adhesive to oxidize and harden. This ensures the adhesive maintains good flowability and tack during installation, guaranteeing smooth dispensing and adhesion. This protective effect is particularly significant during long-term storage or transportation in harsh environments, effectively reducing the risk of adhesive failure.

[0038] When the polycarbonate sheet 1 compresses the adhesive storage pressure bladder 31, the adhesive inside the pressure bladder 3 impacts the duckbill-type check valve, causing the duckbill-type check valve to open on both sides, and the outlet of the duckbill-type check valve gradually increases. At this time, the force on both sides when the duckbill-type check valve opens shows an outward expansion trend, causing slight stretching at the edge where the aluminum foil sealing film contacts the check valve 33.

[0039] At this point, the expansion force on both sides of the one-way valve 33 makes the stress concentration points of the aluminum foil sealing film more susceptible to stress; on the other hand, the impact force of the adhesive will concentrate on the central area or stress concentration points of the aluminum foil sealing film. The combined force of the two reaches the rupture threshold of the protective film, causing it to rupture at this time. This ensures the integrity of the protective film during transportation and, with the assistance of the opening of the one-way valve 33 during installation, allows the protective film to rupture smoothly under the impact of the adhesive, ensuring smooth adhesive extrusion and achieving effective bonding between the polycarbonate sheet 1 and the splicing component 2.

[0040] The inner layer of the gel storage pressure bladder 31 is an aluminum foil-PE composite film, and the outer layer of the gel storage pressure bladder 31 is a high-elasticity silicone sleeve.

[0041] The inner aluminum foil-PE composite film provides excellent barrier properties. The aluminum foil layer effectively blocks the penetration of oxygen, moisture, and ultraviolet rays, preventing the adhesive stored inside from deteriorating or curing due to oxidation, moisture, or light exposure, ensuring that the adhesive maintains good adhesion and flowability during long-term storage. The PE film has good chemical stability and high compatibility with the adhesive, and will not affect the adhesive performance due to chemical reactions between materials, providing a stable storage environment for the adhesive. Therefore, the inner layer preferably uses an aluminum foil-PE composite film with certain tear resistance to prevent the adhesive from breaking through the inner layer under high pressure; the outer high-elasticity silicone sleeve acts as a buffer and protector, reducing the risk of damage to the adhesive storage pressure bladder 31 due to collision and friction during transportation and installation, and extending its service life.

[0042] The distance between the one-way valve 33 and the opening of the receiving groove 11 is less than the distance between the one-way valve 33 and the inner sidewall 113 of the receiving groove 11.

[0043] The one-way valve 33, positioned near the groove opening, allows the adhesive to quickly contact and fill the gap between the polycarbonate sheet 1 and the receiving groove 11 during the initial insertion of the polycarbonate sheet 1. When the polycarbonate sheet 1 is inserted from the groove opening, the area of ​​the adhesive storage pressure bladder 31 near the opening is first compressed. At this point, because the one-way valve 33 is closer to the groove opening, the extruded adhesive can immediately act on the part where the polycarbonate sheet 1 has just entered. As the polycarbonate sheet 1 continues to be inserted, the adhesive can gradually spread inwards along the contact surface, preventing the gap from not being sealed in time during the initial insertion of the polycarbonate sheet 1 due to the one-way valve 33 being too deep, thus reducing the risk of rainwater seeping in from the groove opening.

[0044] The one-way valve 33 is located near the groove opening, which allows the area to receive more adhesive, forming a thicker adhesive layer. This enhances the connection strength between the polycarbonate sheet 1 and the splice 2 at the entrance, effectively resisting the external forces generated by the polycarbonate sheet 1 due to thermal expansion and contraction, wind, etc., reducing the possibility of loosening or gaps at the groove opening, and further ensuring the stability of the overall structure.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
