A waterproof structure for building curtain wall

Abstract

The utility model provides a building curtain wall waterproof structure, which solves the problem that the sealing glass bead is easily affected by temperature changes and expands and contracts, resulting in a gap between the sealing glass bead and the curtain wall glass, and affecting the overall waterproof sealing performance of the building curtain wall. The utility model arranges a spring on the internal threaded stud on the installation mechanism, so that when the bolt is rotated, the head of the internal threaded stud moves forward to squeeze the spring, and the spring applies a force toward the rear to the internal threaded stud. The spring applies a force toward the rear to the bolt through the internal threaded stud, so that the bolt can always apply a force toward the rear to the mounting plate. Even if the sealing glass bead is easily affected by temperature changes and expands and contracts, the mounting plate can always clamp the curtain wall glass to the front and rear sealing glass bead through the bolts, avoiding the gap between the sealing glass bead and the curtain wall glass.

Description

It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. Most building curtain walls are glass curtain walls. Common glass curtain wall structures include: open frame, semi-hidden frame, hidden frame, point type, and full glass type. Among them, the open frame glass curtain wall is the most traditional form, the most widely used, and has reliable working performance. The glass of the open frame glass curtain wall is inlaid in the aluminum frame to form a curtain wall component with aluminum frames on all four sides. The curtain wall components are inlaid on the beams and columns to form a facade with exposed beams and columns and obvious aluminum frame divisions. Compared with the hidden frame glass curtain wall, it is easier to meet the construction technology level requirements.

[0021] Embodiment 1: A building curtain wall waterproof structure, such as Figure 1-3 As shown, it includes a curtain wall frame 1, which is a criss-cross "well" type structure. A mounting mechanism 2 is provided in front of the curtain wall frame 1 along its extension direction, and a curtain wall glass 3 is fixed on the mounting mechanism 2. The mounting mechanism 2 is used to fix the curtain wall glass 3 in front of the curtain wall frame 1. Specifically, the mounting mechanism 2 includes a mounting plate 21, and the mounting plate 21 is located in front of the curtain wall frame 1. Two sealing glass strips 22 are detachably fixed on one side of the mounting plate 21 opposite to the curtain wall frame 1, and the end of the curtain wall glass 3 is arranged between the two corresponding sealing glass strips 22 at the front and rear.

[0022] A U-shaped profile 23 with a rear opening structure is fixedly provided at the middle of the front end of the curtain wall frame 1. A plurality of internally threaded studs 24 with a front opening structure and spaced apart along the extension direction thereof are provided in the U-shaped profile 23. The heads of the internally threaded studs 24 are regular hexagonal nuts. Both sides of the heads of the internally threaded studs 24 slide against both sides of the inner wall of the U-shaped profile 23 to prevent the internally threaded studs 24 from rotating in the U-shaped profile 23. A long groove which is arranged along the extension direction thereof and is transparent from front to back is provided at the front end of the U-shaped profile 23. The internally threaded studs 24 slide through the long groove. The diameter of the heads of the internally threaded studs 24 is larger than the groove width of the long groove, so that the internally threaded studs 24 cannot rotate from The internal threaded stud 24 is completely passed through the long groove, the front end of the internal threaded stud 24 passes through the long groove, and the internal thread of the internal threaded stud 24 is penetrated by a bolt 25. A plurality of oblong grooves 5 are opened on the mounting plate 21, and the plurality of oblong grooves 5 correspond to the plurality of bolts 25 front and back. The front end of the bolt 25 passes through the oblong groove 5 and extends to the front side of the mounting plate 21. The oblong groove 5 provides a larger installation margin for the internal threaded stud 24 and the bolt 25, so that the bolt 25 can be installed in place more easily, thereby improving the assembly efficiency. The head of the bolt 25 is located on the front side of the mounting plate 21, and the mounting plate 21 is used to clamp and fix the curtain wall glass 3 between the front and rear two sealing glass strips 22 through the bolt 25.

[0023] A spring 26 is sleeved on the internal threaded stud 24, and the spring 26 is located between the head of the internal threaded stud 24 and the front end of the U-shaped profile 23; when the mounting plate 21 is driven to move by rotating the bolt 25 to clamp the curtain wall glass 3 between the front and rear two sealing glass strips 22, the head of the internal threaded stud 24 moves forward to squeeze the spring 26, and the spring 26 applies a force toward the rear to the internal threaded stud 24, and the spring 26 applies a force toward the rear to the bolt 25 through the internal threaded stud 24, so that the bolt 25 can always apply a force toward the rear to the mounting plate 21, even if the sealing glass strip 22 is easily affected by temperature changes and has thermal expansion and contraction, the mounting plate 21 can always clamp the curtain wall glass 3 between the front and rear two sealing glass strips 22 through the bolt 25, so as to avoid the formation of a gap between the sealing glass strip 22 and the curtain wall glass 3, resulting in the overall waterproof sealing performance of the building curtain wall being affected.

[0024] The space between the front end of the U-shaped profile 23 and the mounting plate 21 is filled with insulation cotton 6, and the front end of the internal threaded stud 24 is inserted into the insulation cotton 6. The insulation cotton 6 can insulate the heat between the U-shaped profile 23 and the mounting plate 21 to avoid the cold bridge phenomenon.

[0025] The mounting plate 21 is a U-shaped plate structure with a rear opening. A cover plate 4 is provided on the front side of the mounting plate 21. The cover plate 4 is a U-shaped plate structure with a rear opening. The cover plate 4 is buckled on the mounting plate 21. The front end of the cover plate 4 is against the front side of the curtain wall glass 3. The head of the bolt 25 is located between the mounting plate 21 and the cover plate 4. The cover plate 4 can protect the head of the bolt 25 and improve the aesthetics of the outer surface.

[0026] A foam rod 7 is fixedly provided between the end of the curtain wall glass 3 and the U-shaped profile 23. The foam rod 7 is used to prevent the end of the curtain wall glass 3 from directly contacting and colliding with the U-shaped profile 23, which may cause damage to the curtain wall glass 3. A sealant 8 is filled between the end of the curtain wall glass 3 and the U-shaped profile 23. The sealant 8 is located in front of the foam rod 7. The sealant 8 can prevent rainwater from entering the room through the gap between the curtain wall glass 3 and the U-shaped profile 23, thereby further enhancing the sealing performance of the building curtain wall.

[0027] Working principle: During construction, the sealing glass molding 22 is installed and fixed at the front end of the curtain wall frame 1, and then a plurality of internal threaded studs 24 with springs 26 are installed in the U-shaped profile 23 from the end of the long groove at a certain interval, and at the same time, the front end of the U-shaped profile 23 is passed through the long groove, and then the end of the curtain wall glass 3 is placed in front of the sealing glass molding 22 located at the rear, and then the mounting plate 21 with the sealing glass molding 22 is placed in front of the curtain wall glass 3, and then the front end of the bolt 25 is passed through the long circular groove 5 and screwed into the internal threaded stud 24, and by gradually rotating the bolt 25, the mounting plate 21 is driven to move and clamp the curtain wall glass 3 between the front and rear sealing glass moldings 22, and at the same time, the head moves forward to squeeze the spring 26, and the spring 26 applies a force toward the rear on the internal threaded stud 24, and the spring 26 applies a force toward the rear on the bolt 25 through the internal threaded stud 24, so that the bolt 25 can always apply a force toward the rear on the mounting plate 21.
