Description

Technical Field

[0001] This utility model relates to the field of building curtain wall decoration technology, and more specifically to the field of curtain wall pressure plate fastening structure with pre-installed adhesive strips. Background Technology

[0002] With the development of modern cities, there is an urgent need for rapid construction of curtain walls. In the traditional curtain wall construction process, the curtain wall pressure plate and sealing strip need to be installed in stages. After on-site cutting, they are then embedded or pasted, which poses a risk of dimensional deviation and is complicated and time-consuming. Most of the sealing strips and covers cannot be disassembled after being fixed, and the whole thing needs to be replaced during maintenance, which is highly dependent on professional construction personnel. The integrated design of the decoration and function of the pressure plate and cover is not fully considered, resulting in a disconnect from the overall decoration of the curtain wall.

[0003] Therefore, how to design a curtain wall pressure plate cover structure with pre-installed adhesive strips that can meet the actual needs of factory prefabrication and rapid on-site installation, while also facilitating later disassembly and maintenance and improving the visual uniformity of the curtain wall, has become an urgent problem to be solved in the field of curtain wall pressure plate cover structures with pre-installed adhesive strips. Utility Model Content

[0004] The purpose of this utility model is to provide a curtain wall pressure plate fastening structure with pre-installed adhesive strips in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] This utility model provides a curtain wall pressure plate cover structure with pre-installed adhesive strips, including a pressure plate structure that can be detachably fixed to the aluminum alloy horizontal frame of the curtain wall by a locking component. The upper and lower ends of the pressure plate structure near the aluminum alloy horizontal frame of the curtain wall are provided with adhesive strip pre-installation parts. Each adhesive strip pre-installation part is inlaid with an adhesive strip. Each adhesive strip pre-installation part includes an inwardly recessed mushroom head-shaped installation groove. Each mushroom head-shaped installation groove has a latching tab limiting protrusion on both the upper and lower sides of the inlet.

[0007] Each rubber strip includes a rubber strip mounting part that mates with a mushroom-shaped mounting groove, a connecting part that snaps between two latching tabs, and a sealing contact part that contacts the aluminum alloy frame or glass of the curtain wall. The connecting part is located at the rubber strip mounting part and the sealing contact part.

[0008] Specifically, the rubber strip installation part (with a mushroom head on the back of the rubber strip) is snapped into the mushroom head-shaped installation groove, and the connecting part and the corresponding two elastic tab limit protrusions form a snap-locking structure. The pressure plate structure is fixedly connected to the aluminum alloy horizontal frame of the curtain wall through the locking assembly. This structure achieves factory prefabrication, rapid on-site installation and convenient maintenance through modular design and functional integration.

[0009] Installation of curtain wall pressure plates with pre-installed sealing strips: The pressure plate structure is transported to the site after the sealing strips are completed in the factory. After the curtain wall glass is installed on site, it is leveled and positioned, and then locked and snapped onto the aluminum alloy horizontal frame of the curtain wall using locking components.

[0010] The pressure plate structure and sealing strips adopt a modular assembly process, integrating the sealing strips with the pressure plate structure body to form pre-assembled sealing strip units. This transfers the traditional on-site cutting process to the factory, avoiding quality defects such as burrs and length deviations in the sealing strips.

[0011] In one embodiment, the shape of the adhesive strip mounting part is a mushroom head shape that matches the shape of the mushroom head-shaped mounting groove, and a cavity structure is provided inside the connecting part.

[0012] Specifically, for the maintenance and replacement of the sealing strip: First, loosen the pan head screws connecting the locking assembly to the aluminum alloy horizontal frame of the curtain wall appropriately; second, locate the pre-drilled rotation mark at the end of the sealing strip, hold the strip by hand, and rotate it 90° clockwise; finally, gently pull along the normal direction of the cover, the mounting part of the sealing strip and the limiting protrusion of the latch will misalign, disengaging from the locking area, and the sealing strip can be pulled out vertically. When installing the sealing strip, align the mounting part of the sealing strip with the mushroom-shaped mounting groove, press vertically until a locking sound is heard, gently pull the strip to confirm there is no looseness, align the rotation mark with the initial position, tighten the pressure plate structure, and then perform a sealing test to verify.

[0013] The maintenance and replacement of the sealing strips requires no tools throughout the process. Single-point disassembly is quick and only the damaged sealing strip needs to be replaced, avoiding the need to disassemble the entire cover. The rotating unlocking mechanism of the sealing strip avoids scratches on the cover surface caused by traditional prying. After the sealing strip is reset, the joint width deviation is ≤0.5mm, which helps to ensure the overall aesthetics of the curtain wall facade.

[0014] In one embodiment, the sealing contact portion is provided with a wavy anti-slip structure on the side away from the adhesive strip mounting portion.

[0015] Specifically, the pre-installation and high-temperature stability verification of the rubber strip are performed. The rubber strip adopts a single-sided corrugated cavity structure. In a 60℃ hot environment, the pre-installation part of the rubber strip is fitted into the mushroom-shaped mounting groove by two elastic latching protrusions. After cooling, pressure is applied to the rubber strip again, so that the two elastic latching protrusions are locked on the connection part, and secondary reinforcement and locking with the spring latch are performed.

[0016] The secondary pressurization after cooling is to achieve double locking. The wave-shaped anti-slip structure and cavity structure design absorb the expansion stress of the curtain wall through asymmetric deformation, avoiding cracking at the interface between the rubber strip and the cover; high-temperature verification is to ensure that the compression rebound rate of the EPDM foam layer is ≥85%, guaranteeing long-term sealing reliability.

[0017] In one embodiment, the pressure plate structure has a U-shaped locking mounting groove recessed into the curtain wall in the middle, and the bottom of the U-shaped locking mounting groove has a pressure plate mounting hole for installing the locking assembly.

[0018] In one embodiment, the locking assembly is a pan head screw that locks the pressure plate structure onto the aluminum alloy horizontal frame of the curtain wall. The side wall of the U-shaped locking mounting groove is provided with two sets of elastic snap-fit ​​ears, and the U-shaped locking mounting groove is provided with a decorative buckle cover that snaps onto the elastic snap-fit ​​ears.

[0019] Specifically, the decorative cover and pan head screws form a concealed screw layout. The decorative cover installation structure involves locking the pressure plate structure with pan head screws, after which the decorative cover is fixed to the U-shaped locking mounting groove via a snap-fit ​​mechanism.

[0020] In one embodiment, the pressure plate structure is made of aluminum alloy.

[0021] In one embodiment, the U-shaped locking mounting groove is provided with two pressure plate tail lugs on the side near the aluminum alloy horizontal frame of the curtain wall, and the two pressure plate tail lugs are hooked onto the aluminum alloy horizontal frame of the curtain wall.

[0022] Specifically, during installation, a dual fixing method is adopted, which uses pan head screws for locking and the tail lugs of the pressure plate for fastening. This ensures the stability of the installation and significantly improves the efficiency of on-site construction.

[0023] In one embodiment, the rubber strip mounting part, the connecting part, and the sealing contact part are integrally formed.

[0024] In one embodiment, the width of the connecting portion is smaller than the width of the adhesive strip mounting portion and the width of the sealing contact portion.

[0025] In one embodiment, the decorative buckle cover is a U-shaped buckle cover with its opening facing the U-shaped locking mounting groove. The outer side wall of the U-shaped buckle cover is provided with an end guide flange and a tail limiting claw that respectively cooperate with two sets of elastic snap-fit ​​hooks.

[0026] During disassembly, insert a non-metallic pry bar into the end seam of the decorative buckle cover and pry at an angle of ≤30° to release the constraint between the end guide flange and the tail limiting claw. Then, slide the decorative buckle cover horizontally along the snap-fit ​​groove to disengage the tail limiting claw from the elastic snap-fit ​​ear, thus completing the non-destructive disassembly. During reassembly, clean the snap-fit ​​groove and check the integrity of the elastic snap-fit ​​ear. Align the end guide flange with the elastic snap-fit ​​ear and push it in. After contacting the damping pad, apply pressure evenly to close the seam.

[0027] Specifically, during disassembly, the elastic snap-fit ​​lugs adaptively compress and deform to avoid plastic damage, while during reassembly, the damping pad contact surface provides pre-tightening force to ensure the sealing accuracy of the decorative cover and the U-shaped locking mounting groove joint. This structure, through the precise cooperation of the tail limiting claw and the end guide flange, enables the independent replacement of a single decorative cover, and the screws and snap-fit ​​parts are completely concealed, ensuring that there are no nail hole defects on the curtain wall facade.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. Factory prefabrication improves construction efficiency and precision: The pressure plate structure and rubber strips are assembled in the factory using a modular assembly process to form standardized pre-assembled units, reducing on-site cutting and secondary installation processes, which greatly improves installation efficiency and precision. Compared with traditional on-site installation processes, it significantly improves construction efficiency.

[0030] 2. Independent disassembly and replacement structure simplifies maintenance process: The decorative buckle and rubber strip are unlocked by rotation and reset by snap-fit ​​design, which supports single-point disassembly without the need for overall replacement; during disassembly, the elastic hooks adapt to compression deformation to avoid plastic damage, and reassembly does not require professional tools, reducing maintenance costs.

[0031] 3. Concealed screw layout optimizes the visual uniformity of the curtain wall: The U-shaped locking mounting groove in the middle of the pressure plate is designed in conjunction with the decorative buckle cover to completely hide the pan head screws and snap-fit ​​structure, achieving a nail hole-free effect on the curtain wall facade; the elastic claws and the end guide flanges work precisely to ensure the joint closure accuracy after the decorative buckle cover is reset, improving the overall decorativeness and appearance consistency of the curtain wall.
