Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and more specifically to a clamping device for exposed frame glass curtain walls. Background Technology

[0002] Traditional glass curtain wall installation is inefficient, typically requiring extensive on-site caulking and bolting. Point-supported curtain walls, while aesthetically pleasing, are technically complex and expensive. Unitized curtain walls, on the other hand, demand sophisticated hoisting equipment and are difficult to maintain and replace later. Currently, various glass curtain wall installation devices exist, but each has its limitations.

[0003] For example, Chinese invention patent application CN220790259U (publication date: April 16, 2024) discloses an energy-saving and environmentally friendly glass curtain wall, including a glass curtain wall body and columns for installing the glass curtain wall body. The columns are equipped with two sets of connectors corresponding to individual glass curtain wall panels. A suspension block is provided on the upper set of connectors, and a connecting block is provided on the lower set of connectors. A pressing block is connected to the connecting block. An upper snap-on plate is provided at the top of the glass curtain wall body, forming a downward-opening suspension groove that engages with the suspension block. A lower snap-on plate is provided at the bottom of the glass curtain wall body, forming an upward-opening pressing groove that engages with the pressing block. This invention provides an energy-saving and environmentally friendly glass curtain wall that uses a curtain wall installation method combining suspension support and downward pressing limit, which is more stable and practical while being easier to operate.

[0004] Chinese invention patent application CN108118809A (published on June 5, 2018) discloses an auxiliary clamping device for aluminum alloy decorative covers of exposed frame glass curtain walls, including two steel pipe slide rails arranged side by side and a clamping assembly sleeved between the two steel pipe slide rails. The clamping assembly includes a clamping handle and a slide rail accessory. The clamping handle is slidably connected to the two steel pipe slide rails through the slide rail accessory, and one end of the clamping handle is pivotally connected to the slide rail accessory.

[0005] In summary, while existing technologies have improved installation convenience, they still have shortcomings in structural stability, three-dimensional adjustment capability, and safety against detachment. How to balance installation efficiency and structural stability, while providing sufficient adjustment margin to accommodate building structural deviations, remains a technical problem that needs to be solved. Summary of the Invention

[0006] To address the aforementioned issues, this application proposes a clamping device for exposed-frame glass curtain walls, comprising: a column, a sliding base, a clamping assembly, a fixing assembly, a glass curtain wall, and a sealing strip; The column extends horizontally or vertically along the exposed frame glass curtain wall and is composed of multiple aluminum alloy chain links connected by elastic hinges. The column is provided with a guide rail near the glass panel, and the guide rail contains a support plate, a first limiting block and a second limiting block. The slide block is slidably engaged with the guide rail. A slot is opened at the center of the upper surface of the slide block, and the bottom of the slide block is provided with a first limiting groove and a second limiting groove that match the first limiting block and the second limiting block. The fastening assembly is inserted into the slot of the slide block by a fastening block. The fastening assembly is equipped with a rotating locking rod. The rotating locking rod rotates 90 degrees around the axis of the fastener and is inserted into the locking slot of the glass curtain wall for primary fixing of the glass curtain wall. The fixing component is located between the clamping component and the glass curtain wall. The clamping handle of the clamping component presses the fixing plate of the fixing component against the surface of the outer glass panel through the adjusting screw, thereby realizing the secondary fixing of the glass curtain wall. The adhesive strip is installed between the fixing component and the outer glass panel and between the inner glass panel and the column.

[0007] Furthermore, the clamping assembly includes a clamping handle, a gasket, an adjusting screw, a fixing groove, a nut, a seal, a locking element, a rotating locking rod, and a locking block.

[0008] Furthermore, the rotating locking rod is symmetrically welded to the outer side of the middle part of the card.

[0009] Furthermore, the card is movably connected to the slide via a card block.

[0010] Furthermore, the adjusting screw passes through the pre-drilled hole in the center of the fixed pressure plate and is threadedly connected to the nut welded in the fixed groove. The sealing element fills the gap between the fixed groove and the adjusting screw.

[0011] Furthermore, the end of the clamping handle has a roller, and a gasket is provided between the roller and the fixing component. The gasket is used to distribute the clamping force and protect the surface of the fixing component.

[0012] Furthermore, longitudinal protrusions are provided on both sides of the fixing groove, and the protrusions are welded to the inner wall of the clamp to form a box-type load-bearing structure.

[0013] Furthermore, the fixing component includes a rubber pad, a fixing plate, a fixing arm, and a limiting hole.

[0014] Furthermore, there are at least four rubber pads, located at the four corners of the fixed pressure plate, for elastic contact with the glass curtain wall.

[0015] Furthermore, the width of the fixed arm gradually narrows from the fixed pressure plate body towards the rubber pad, and there is an arc transition between the two fixed arms to improve rigidity and reduce weight.

[0016] Furthermore, the slot of the slide is a square slot, and the bottom of the card is provided with an inverted trapezoidal card block. After the card block is inserted into the slot, it is limited along the guide rail direction and self-locked in the vertical direction.

[0017] Furthermore, the guide rail of the column is integrally formed with the support plate, and there are two of each of the first and second limiting blocks, which are symmetrically arranged on the top surface of the support plate and protrude upwards to limit the sliding block.

[0018] Furthermore, the glass curtain wall consists of an outer frame and double-layered glass panels embedded in the frame. The outer frame has a locking groove on the side facing the column. After the rotating locking rod rotates 90°, it is locked into the locking groove. Molecular sieves are filled between the locking groove and the glass cavity for moisture absorption.

[0019] Furthermore, the adhesive strip is embedded in the groove on the top surface of the column, and the thickness of the adhesive strip is slightly higher than the edge of the groove, so that the adhesive strip is higher than the edge of the groove after being embedded, which is used to buffer the load of the glass curtain wall.

[0020] Furthermore, a method for installing a clamping device for an exposed-frame glass curtain wall includes the following steps: Step S1: Connect the columns according to the height of the curtain wall and fix them to the main structure; Step S2: Embed the adhesive strip into the groove on the top surface of the column; Step S3: Insert the slide block into the end of the guide rail, slide it to the appropriate position and fix it; Step S4: Insert the clip of the snap-fit ​​component into the sliding block slot, rotate the clip to drive the rotating locking rod into the locking slot of the glass curtain wall, and complete the first-level fixation; Step S5: Rotate the clamping handle to the appropriate position by adjusting the screw, and press down the clamping handle to make the fixing component press against the glass curtain wall, thus completing the secondary fixing; Step S6: Repeat the above operation until all glass panels are installed.

[0021] Compared with existing technologies, the advantages and effects of this application are as follows: 1. This application adopts a mechanical clamping structure with a fixed component, a clamping handle, and a rotating locking rod for fixing. The clamping handle uses the lever principle to apply force evenly to the glass plate through the fixed pressure plate. The clamping force can be adjusted and maintained by adjusting the screw, avoiding problems such as uneven impact force, chipping of the coating on the cover surface, and exposed aluminum caused by manual hammering in traditional installation methods.

[0022] 2. This application incorporates adhesive strips between the fixing components and the outer glass panel, as well as between the inner glass panel and the columns, forming a buffer system that provides all-around protection for the glass curtain wall. This prevents scratches or breakage caused by direct contact between the glass and hard metal, and avoids the risk of glass breakage due to excessive point stress. Furthermore, molecular sieves are installed near the columns of the glass curtain wall for moisture absorption, ensuring the airtightness and watertightness of the curtain wall.

[0023] 3. This application uses a column made of multiple chain links connected by hinges, which can be flexibly adapted to various building facades, including curved and curved curtain walls, ensuring convenient installation while reducing the difficulty of curtain wall construction.

[0024] 4. The longitudinal protrusions on both sides of the fixing groove of this application are welded to the inner wall of the clamp to form a robust "box-type load-bearing structure," which evenly distributes the enormous pressure generated by the clamping handle, avoids local stress concentration, and improves the rigidity and durability of the entire clamping device. Furthermore, if it is necessary to replace or repair a piece of glass, simply reverse the operation: loosen the adjusting screw and rotate to open the locking lever, facilitating maintenance.
