Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall construction, specifically a waterproof installation structure for curtain walls. Background Technology
[0002] A curtain wall is a lightweight wall structure installed on the exterior of a building using a keel system. It does not bear weight and serves only a decorative purpose. Water seepage and leakage are prone to occur at the gaps in curtain wall panels, therefore waterproofing is necessary during installation. The utility model patent application number CN202322173197.6 describes a method of sealing the gaps by installing sealing strips on the keel at the curtain wall panel gaps. However, this sealing method is prone to poor contact between the sealing strip and the curtain wall panel due to positional errors during installation, leading to localized seal failure and leaks. Some curtain walls use silicone sealant to seal the gaps after installation, but this method suffers from rapid aging and cracking due to sealant leakage, resulting in seal failure. Summary of the Invention
[0003] This utility model provides a waterproof installation structure for curtain walls, with the aim of improving the reliability and durability of the waterproof curtain wall structure.
[0004] The technical solution includes an installation frame composed of longitudinal and transverse skeletons. Each skeleton of the installation frame has a spacer plate parallel to it on its outer surface. It also includes a sealing strip and a fixing strip. The sealing strip is embedded in the gap of the curtain wall glass, and the inner side of the sealing strip contacts the spacer plate. The fixing strip has a T-shaped cross section. The head of the T-shape is embedded in the gap of the curtain wall glass and contacts the sealing strip. The tail of the T-shape presses against the outer surface of the curtain wall glass. It also includes a fixing bolt. The spacer plate has threaded holes. The fixing bolt passes through the fixing strip and the sealing strip and is screwed into the threaded holes of the spacer plate.
[0005] The width of the portion of the fixing strip embedded in the glass gap is less than the width of the gap, and a cavity is formed between the fixing strip and the two sides of the glass. The cavity is filled with glass glue to form a sealing layer.
[0006] The sealing strip has multiple layers, and a separator is provided between two adjacent layers of sealing strip.
[0007] It also includes a temporary fixing plate, which is a flat plate with a length greater than the width of the glass gap. The temporary fixing plate has clearance holes for the fixing bolts to pass through.
[0008] This invention uses a fixing strip and a spacer plate to press the sealing strip together, forming a multi-layer conventional seal in the glass gap. Then, by injecting glass glue into the cavity formed between the fixing strip and the glass side, a glue-filled sealing layer is formed that can completely fill the gap, ensuring reliable waterproof performance at the installation gap. In addition, neither the sealing strip nor the glue layer leaks out, which can greatly slow down the aging rate of the sealing strip and glass glue, and has long-term reliability.

[0015] Referring to the accompanying drawings, this utility model includes an installation frame 1 composed of longitudinal and transverse skeletons. The installation frame 1 is fixed to the wall by expansion bolts or pre-embedded bolts on the wall. Each skeleton of the installation frame 1 has a parallel partition plate 2 on its outer surface. The longitudinal and transverse partition plates 2 form a rectangular installation grid. The curtain wall glass is installed within the grid and is limited by the partition plates 2 on all sides. It also includes a sealing strip 3 and a fixing strip 4. The sealing strip 3 is embedded in the gap of the curtain wall glass, and the inner side of the sealing strip 3 contacts the partition plate 2. The fixing strip 4 has a T-shaped cross-section, and the head of the T-shape is embedded in the curtain wall glass. In the gap of the wall glass, it contacts the sealing strip 3. The T-shaped tail presses against the outer surface of the curtain wall glass to prevent the curtain wall glass from falling off. It also includes fixing bolts 5. The partition plate 2 has threaded holes 6. Both the sealing strip 3 and the fixing strip 4 are provided with clearance holes for the fixing bolts 5 to pass through. The fixing bolts 5 pass through the fixing strip 4 and the sealing strip 3 and are screwed into the threaded holes 6 of the partition plate 2, thereby pressing the fixing strip 4 and the sealing strip 3 together and fixing the curtain wall glass. At the same time, the sealing strip 3 is compressed so that the two sides of the sealing strip 3 are pressed tightly against the sides of the curtain wall glass to seal it.
[0016] The width of the portion of the fixing strip embedded in the glass gap is less than the width of the gap. A cavity 7 is formed between the fixing strip and the sides of the glass. The cavity 7 is filled with glass glue to form a sealing layer. The specific construction method is to install the fixing panel after installing the sealing strip 3, fill the glass gap with glass glue, and press the fixing strip 4 into the gap immediately before the glass glue solidifies. Excess glass will be squeezed out, and the cavity 7 will be filled with glass glue. After solidification, a sealing layer is formed. The overflowing glass glue is wiped off before solidification.
[0017] The sealing strip 3 has multiple layers, and a separator 8 is provided between two adjacent sealing strips 3 to form a multi-layer seal.
[0018] It also includes a temporary fixing plate 9, which is a flat plate with a length greater than the width of the glass gap. The temporary fixing plate 9 has clearance holes for the fixing bolts 5 to pass through. After the sealing strip 3 is installed, the fixing strip 4 cannot be installed temporarily because glass glue needs to be applied. At this time, the temporary fixing plate 9 is pressed tightly to the outside of the glass gap with the fixing bolts 5 to temporarily fix the glass. After the glass glue is applied, the fixing strip 4 is installed. Then, the temporary fixing plate 9 at the gap is removed and the fixing strip 4 is installed.
[0019] During installation, the mounting frame 1 is first fixed to the wall using expansion bolts or pre-embedded bolts. Then, the curtain wall glass panels are installed one by one within the squares of the mounting frame 1. The curtain wall glass is fixed and limited around its perimeter by partition plates 2. Next, sealing strips 3 and partition strips 8 are embedded into the gaps between adjacent curtain wall glass panels. Then, temporary fixing plates 9 are placed on the outside of the gaps, and fixing bolts 5 are screwed on to tighten the temporary fixing plates 9, temporarily fixing the curtain wall glass. Figure 6 As shown; after the curtain wall glass in a certain area is installed, apply glass sealant to the gaps in the curtain wall glass. Before the glass sealant hardens, remove the temporary fixing plate 9 outside the gap, press the fixing strip 4 into the gap, and the excess glass sealant is squeezed out. The cavity 7 between the fixing strip 4 and the side of the glass is filled with glass sealant. Install the fixing bolts 5 to press the fixing strip 4 tightly, and wipe away the overflowing glass sealant. After the glass sealant hardens, it forms the first level of waterproof layer, and the sealing strip 3 forms the subsequent multi-level waterproof layer.
[0020] For aesthetic purposes, decorative buckles can be installed on the outside of the fixing strip 4 to cover the fixing strip 4 and the fixing bolts 5.
[0021] This invention ensures reliable waterproofing at installation gaps through the sealing strip 3 and the adhesive sealing layer; in addition, neither the sealing strip 3 nor the adhesive layer leaks out, which can greatly slow down the aging rate of the sealing strip 3 and the glass glue, and has long-term reliability.
