Description

Technical Field

[0001] This application relates to the field of curtain wall support equipment technology, and in particular to a detachable curtain wall support column. Background Technology

[0002] Currently, most of the double-cavity curtain wall support columns used in the building curtain wall field adopt an integrated extrusion molding structure. The overall length of the profile is large and the weight of a single column is heavy, making it difficult to operate during on-site transportation and hoisting construction. The integrated molding column cannot be disassembled and installed in sections, which makes high-rise curtain wall construction highly dependent on lifting equipment, complicated installation procedures, and requires replacement of the entire column after partial damage, resulting in high maintenance costs.

[0003] Meanwhile, the existing curtain wall columns' matching light strips, decorative strips, and other decorative elements can only be fixed using structural adhesive or cable ties. Adhesive bonding is highly susceptible to environmental temperature and humidity fluctuations, the adhesive is prone to aging and peeling, and its waterproofing and durability are poor. Cable ties damage the coating on the column surface, affecting the curtain wall's appearance. Both installation methods are irreversible fixing structures, making disassembly difficult during later light strip maintenance and decorative component replacement, easily causing damage to the profiles and decorative components. This lack of ease of assembly and disassembly fails to meet the modular, rapid disassembly and maintenance requirements of modern curtain walls. Summary of the Invention

[0004] To improve the ease of operation of detachable curtain wall support columns, this application provides a detachable curtain wall support column.

[0005] This application provides a detachable curtain wall support column, which adopts the following technical solution: A detachable curtain wall support column includes a fixing member, a support column, and a connector. The curtain wall is sandwiched between the fixing member and the support column. The fixing member and the support column are detachably connected through the connector. The support column is detachably connected by a first column body and a second column body. A first ear plate and a second ear plate are connected to the first column body. A clamping assembly is installed on the first column body, and the clamping assembly is installed between the first ear plate and the second ear plate.

[0006] By adopting the above technical solution, the support column is divided into a first column and a second column structure, which can be transported and assembled in sections on site, significantly reducing the weight of a single profile and simplifying the hoisting and installation process. When a column is partially damaged, the corresponding column can be replaced individually without replacing the entire column, thus reducing maintenance costs. Independent clamping components are also provided to hold light strips and decorative parts, eliminating the need for adhesive or binding methods. This allows for quick disassembly and non-destructive replacement of decorative parts, comprehensively improving the ease of operation throughout the entire process of curtain wall column construction, maintenance, and decoration replacement.

[0007] In one specific implementation, the clamping assembly includes a guide rail mounted on the first column, a slide plate slidably mounted on the guide rail, and two clamping strips rotatably mounted on the slide plate to clamp the ornament. The ornament is clamped between the two clamping strips. A fixing plate for constraining the clamping strips is mounted on the first column, the fixing plate being mounted close to the guide rail, and a stop block for limiting the movement of the clamping strips is slidably mounted on the fixing plate.

[0008] By adopting the above technical solution, the vertical installation position of the decorative parts can be adjusted by sliding the skateboard along the guide rail; the two sets of rotatable clamping strips can be adapted to light strips and decorative strips of different thicknesses, with a wide clamping range; the fixing plate and the stop block cooperate to limit and lock the clamping strips, ensuring firm clamping, and the decorative parts can be stably fixed without glue or cable ties.

[0009] In one specific implementation, a control component for controlling the movement of the stop is installed on the fixed plate. A guide groove is provided on the fixed plate. The control component includes a movable plate, which is slidably mounted on the fixed plate through the guide groove. The movable plate extends directly below the connection position between the clamp and the slide plate. A spring is installed on the movable plate, with one end of the spring away from the movable plate connected to the fixed plate. A pull rod is installed on the movable plate, and a sliding rod is connected to the pull rod. A sliding groove is provided on the stop, which is inclined. The sliding rod is inserted into the sliding groove and slidably connected to the stop.

[0010] By adopting the above technical solution, pressing the movable plate will drive the slide bar to slide along the inclined slide groove, driving the two side blocks to separate and release the clamping bar limit. The slide plate can be directly slid to adjust the position of the decorative parts or remove the decorative parts. After the movable plate is released, the spring will automatically rebound, the block will reset and lock the clamping bar. The disassembly and assembly operations can be completed with one click, without the need for additional tools, and the operation is simple and efficient.

[0011] In one specific implementation, a push plate is mounted on the movable plate, and the push plate extends out of the guide groove and is slidably connected to the fixed plate.

[0012] By adopting the above technical solution, the exposed push plate provides a force point for the pressing operation, allowing construction workers to press and unlock by hand, thus improving the convenience of operation.

[0013] In one specific implementation, the clamping strips are fitted with clamping pads on their adjacent sides, the clamping pads being made of rubber.

[0014] By adopting the above technical solution, the rubber pad increases the friction between the rubber pad and the decorative parts, preventing slippage and detachment; at the same time, the flexible material buffers the clamping force, preventing the hard clamping strip from scratching the surface of the light strip and decorative parts, thus playing a protective role.

[0015] In one specific implementation scheme, the fastener has a first lug formed on the side near the curtain wall, and a first connecting groove is formed on the fastener through the first lug; the first column has a second lug formed on the side near the curtain wall, and a positioning groove is formed on the first column through the second lug; the connector includes a connecting plate, and the connecting plate has a second connecting groove for accommodating bolts on the side near the first column, and a pad is bolted between the connecting plate and the first column; the connecting plate has a third connecting groove formed on the side near the fastener, and the third connecting groove is opposite to the first connecting groove, and a retaining plate is engaged on the connecting plate through the third connecting groove, with the end of the retaining plate away from the connecting plate engaging in the first connecting groove on the fastener.

[0016] By adopting the above technical solution, the fastener and the first column adopt a detachable connection structure with a clamping plate and bolt locking. During assembly, the clamping plate is first clamped and pre-positioned, and then the bolts are tightened, ensuring precise installation and alignment. The pad fills the gap, improving the connection sealing and structural stability. The curtain wall and the column are firmly clamped and fixed. During disassembly and assembly, the fastener and the support column can be separated by reverse disassembly.

[0017] In one specific implementation, the fastener has first lugs formed on both sides of the first lug, and a sealing pad is installed on the fastener through the first lugs; the first column has second lugs formed on both sides of the second lug, and a sealing pad is also installed on the first column through the second lugs.

[0018] By adopting the above technical solution, the sealing gaskets can be quickly installed on both sides of the mounting ears. The sealing gaskets fit the curtain wall panel, sealing the assembly gap between the curtain wall and the column, improving the overall waterproof and dustproof performance of the curtain wall. The gaskets can be disassembled and installed without adhesive, and can be replaced individually after aging.

[0019] In one specific implementation scheme, the first column is formed with two first folded ears on the side near the second column, and the first folded ears are both oriented to the same side. The second column is formed with a first limiting groove to accommodate the first folded ears, and the second column is formed with a second folded ear. The first column is formed with a second limiting groove to accommodate the second folded ear. The first column and the second folded ear are tightened and fixed by screws.

[0020] By adopting the above technical solution, the first folding ear and the first limiting groove, and the second folding ear and the second limiting groove are interlocked to form a concave-convex positioning structure. During splicing, they are automatically aligned to prevent the two columns from shifting to the left or right. After the insertion, the screws are tightened to fix them. The split columns are spliced ​​to form a complete double-cavity support column. When disassembling, the screws can be removed to separate them, making segmented transportation, maintenance and replacement flexible.

[0021] In one specific implementation scheme, a first fastening platform is formed on the first ear plate, and a third folded ear is formed on the side of the first ear plate near the curtain wall; a second fastening platform is formed on the second ear plate, and a cover plate is detachably installed on the first ear plate and the second ear plate, and a fastening plate that engages with the first fastening platform and the second fastening platform is connected to the cover plate.

[0022] By adopting the above technical solution, the cover plate is pre-fixed to the buckle plate and the buckle platform, and then locked to the third folding ear with screws. It can cover the installation area of ​​the clamping components, cover the internal structure and improve the cleanliness of the curtain wall appearance. The cover plate is detachable and can be opened to directly operate the clamping components, which is convenient for the inspection and replacement of light strips and decorative parts.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The support column adopts a separate and detachable splicing structure of the first column and the second column, abandoning the traditional one-piece molded double-cavity column. The profile can be transported in sections and assembled on site, reducing the difficulty of hoisting construction. In case of local damage, a single column section can be replaced, which greatly reduces maintenance costs.

[0024] 2. Based on the structure of the first column, a special clamping component is set to hold the light strip and decorative parts, replacing the traditional pasting and binding method. The clamping strip can be quickly unlocked and locked by pressing the push plate. The decorative parts can be disassembled and assembled without damage, which is convenient for later maintenance and replacement. The rubber clamping pads also protect the surface of the decorative parts.

[0025] 3. The fasteners and support columns are detachably connected by snap-fit ​​bolts, and equipped with hanging ear-type sealing gaskets, which ensures good sealing of the curtain wall assembly and simple disassembly and assembly process; the split columns are connected by concave and convex folding ears for precise splicing and positioning, and the overall structure is stable and reliable.

The third connecting groove 312 is also a dovetail groove and is opposite to the first connecting groove 111. A retaining plate 33 is engaged with the connecting plate 31 through the third connecting groove 312. The end of the retaining plate 33 away from the connecting plate 31 is engaged in the first connecting groove 111 on the fixing member 1.

[0042] When assembling the fastener 1 and the first column 21, first install the sealing gasket in the first mounting groove 121 and the second mounting groove 2121. Then, snap the connecting plate 31 into the fastener 1 using the clamping plate 33. Finally, tighten and fix the fastener 1, connecting plate 31, pad 32, first column 21, and curtain wall using bolts. It should be noted that the bolt connection positions are close to both ends of the first column 21.

[0043] Reference Figure 3 , Figure 4 and Figure 6 The first column 21 is connected to the second column 22 on the side away from the curtain wall. The first column 21 has two first folding ears 213 on the side closer to the second column 22. The first folding ears 213 are all facing the same side. The second column 22 has a first limiting groove 221 to accommodate the first folding ears 213 and a second folding ear 222. The first column 21 has a second limiting groove 214 to accommodate the second folding ear 222.

[0044] When assembling the second column 22 onto the first column 21, align the second folding lug 222 with the second limiting groove 214 on the first column 21, insert the second folding lug 222 into the second limiting groove 214, and then push the second column 22 to slide so that the first folding lug 213 is inserted into the first limiting groove 221. At this time, the second folding lug 222 abuts against the wall of the first column 21. Drive screws from one side of the first column 21 toward the second folding lug 222 to tighten and fix the first column 21 and the second folding lug 222. Then, tighten and fix the first column 21 and the second column 22 by driving bolts into the walls of the first column 21 and the second column 22 that are close to each other.

[0045] Reference Figure 1 and Figure 3 A first ear plate 215 and a second ear plate 216 are fixedly connected to the first column 21. The first ear plate 215 is closer to the curtain wall than the second ear plate 216. A first fastening platform 2151 is formed on the first ear plate 215. A third folding ear 2152 is formed on the side of the first ear plate 215 closest to the curtain wall. A second fastening platform 2161 is formed on the second ear plate 216. A cover plate 217 is detachably installed on the first ear plate 215 and the second ear plate 216. Two fastening plates 2171 are fixedly connected to the cover plate 217.

[0046] When the cover plate 217 is installed on the first column 21, the buckle plate 2171 is inserted between the first ear plate 215 and the second ear plate 216, so that the buckle plate 2171 is fastened to the first buckle platform 2151 and the second buckle platform 2161 respectively to complete the initial fixation. Then, screws are driven in from one side of the cover plate 217 toward the third folding ear 2152 to complete the second fixation.

[0047] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 A clamping assembly 4 for clamping light strips or decorations is installed on the first column 21. The clamping assembly 4 is installed between the first ear plate 215 and the second ear plate 216. The clamping assembly 4 includes a guide rail 41, which is fixedly installed on the first column 21. The guide rail 41 is an L-shaped plate. A sliding plate 42 is slidably installed between the guide rail 41 and the first column 21. Two clamping strips 43 are rotatably installed on the sliding plate 42. A clamping pad 431 is fixedly installed on one side of the clamping strips 43 that are close to each other. The clamping pad 431 is made of rubber.

[0048] Two fixing plates 44 are fixedly installed on the first column 21. The two fixing plates 44 are respectively installed close to the two guide rails 41. The fixing plates 44 are also L-shaped plates, with an arc surface 441 at the end of the fixing plate 44 near the clamping strip 43. A stop block 45 for limiting the clamping strip 43 is slidably installed on the fixing plate 44. A control component 46 for controlling the movement of the stop block 45 is installed on the fixing plate 44. The fixing plate 44 has a guide groove 442. The control component 46 includes a movable plate 461, which is slidably installed on the fixing plate 44 through the guide groove 442. The sides of the two movable plates 461 that are close to each other extend out of the guide groove 442 and extend directly below the connection position between the clamping strip 43 and the slide plate 42. A spring 462 is fixedly installed on the movable plate 461, with the end of the spring 462 away from the movable plate 461 fixedly connected to the fixing plate 44. A pull rod 463 is fixedly installed on the movable plate 461, and a slide rod 464 is fixedly installed on the pull rod 463. A slide groove 451 is provided on the stop block 45. The slide groove 451 is inclined, and the slide grooves 451 on the two stops 45 form an inverted V-shape. The slide rod 464 is inserted into the slide groove 451 and slidably connected to the stop block 45. A push plate 465 is fixedly installed on the movable plate 461. The push plate 465 extends out of the guide groove 442 and slidably connects to the fixed plate 44.

[0049] Insert the LED strip or LED wire into the two clamping strips 43. When inserting the LED strip, if one end of the LED strip is fixed first, then you need to leave enough length for the LED strip to move with the clamping strip 43. Pinch the clamping strip 43 to clamp the LED strip, and then push the clamping strip 43 into the two fixing plates 44. After one end of the clamping strip 43 is inserted between the two fixing plates 44, the fixing plates 44 block the clamping strip 43, and the clamping strip 43 is still in the state of clamping the LED strip. Then you can pull the LED strip or push the sliding plate 42 to make the clamping strip 43 move along the fixing plate 44. When the clamping bar 43 moves, the push plate 465 is pressed down, which drives the movable plate 461 to move downward. The movable plate 461 drives the pull rod 463 to move downward. The pull rod 463 drives the slide rod 464 to slide in the guide groove 442 on the stop block 45. Through the action of the oblique guide groove 442, the slide rod 464 will squeeze the stop block 45, causing the two stop blocks 45 to move away from each other, thereby moving the stop block 45 out of the movement path of the clamping bar 43. When the clamping strip 43 moves between the stop block 45 and the movable plate 461, the push plate 465 is released. The spring 462 rebounds and drives the push plate 465 to move upward. The push plate 465 drives the slide rod 464 to move and push the stop block 45 out of the fixed plate 44 so that the stop block 45 covers the side of the clamping strip 43 away from the push plate 465 again. Finally, the push plate 465 will abut against the clamping strip 43. The spring 462 pulls the push plate 465 so that the clamping strip 43 is clamped between the push plate 465 and the stop block 45, thereby completing the fixing and positioning of the light strip.

[0050] The implementation principle of this application embodiment is as follows: This application splits the traditional integrated double-cavity column into two separate profiles, the first column 21 and the second column 22. The profiles are quickly assembled by using the folded ears on the first column 21 and the limiting grooves on the second column 22 for limiting insertion and screw locking. The single profile is lightweight, which greatly reduces the difficulty of transportation and hoisting. Local damage can be replaced individually, solving the problem of inconvenience in disassembling and repairing integrated profiles.

[0051] The curtain wall and the supporting column 2 are assembled using a detachable connector with a pre-clamped bolt locking plate 33, and a sealing gasket, which makes disassembly and assembly convenient and provides excellent sealing and waterproofing.

[0052] Based on the shape and structure of the first column 21, an independent clamping component 4 is added to replace the pasting and binding of the decorative light strip: two sets of rotatable clamping strips 43 clamp the decorative parts, and rubber clamping pads 431 provide protection and anti-slip; pressing the exposed push plate 465 will activate the spring 462, slide rod 464, and inclined slide groove 451 to drive the stop block 45 to move back, unlock the clamping strips 43 to slide freely to adjust the position or remove the decorative parts, and automatically lock when released. No glue or cable ties are needed throughout the process, and the decorative parts can be quickly and easily disassembled without damage, which is convenient for later maintenance and replacement.

[0053] The matching detachable cover plate 217 covers the clamping components in 4 areas, which not only ensures the aesthetics of the curtain wall facade, but also allows direct operation of the internal clamping structure by opening the cover plate 217, further improving the overall ease of use.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
