Description

Technical Field

[0001] The present invention relates to the technical field of glass curtain walls, and particularly to a point-supported glass curtain wall structure and a construction method thereof. Background Art

[0002] Curtain wall projects are mainly applicable to high-rise urban buildings, large-span buildings, special-shaped buildings, building daylighting roofs, public buildings or building complexes, such as high-class office buildings, hotels, stadiums, airports, stations, convention centers, shopping malls, etc. As the outer enclosure structure of a building, a building curtain wall can meet the external decoration needs of the building through different facing materials and different structures.

[0003] When installing the existing point-supported glass curtain wall, first, a screw is passed through the installation hole of the glass curtain wall, then the screw is passed through the connecting claw, and then fixed by using a nut. Since the nut is located between the skeleton and the glass curtain wall, if a certain piece of glass curtain wall is broken due to external reasons, it is inconvenient for the staff to turn the bolt to replace the glass curtain wall. For this reason, we propose a point-supported glass curtain wall structure and a construction method thereof. Summary of the Invention

[0009] Optionally, a reinforcing arc rod is fixedly installed at the bottom end of the connecting claw. A second sealing pad is sleeved on the side end of the insertion rod of the limiting ring. Opposite sides of the first sealing pad and the second sealing pad are both in contact with the curtain wall main body.

[0010] Optionally, a mounting groove is opened at the top end of the fixed column. One end of the connecting claw is inserted into the mounting groove. A threaded hole is opened on one side of the connecting claw. A first bolt is provided on one side of the fixed column. The first bolt passes through the threaded hole and is threadedly connected to the fixed column. The fixed column and the connecting column are fixed by a second bolt.

[0011] Optionally, a plugging groove is opened on one side of the framework. The connecting column is inserted into the plugging groove. A cavity is opened inside the framework. A bidirectional screw rod is rotatably installed in the cavity of the framework. L-shaped insertion blocks are threadedly installed on both sides of the bidirectional screw rod.

[0015] A construction method for a glass curtain wall of a point-supported glass curtain wall structure comprises the following steps:

[0016] a. First, fix the frame to the outside of the exterior wall;

[0017] b. Connect the connecting column to the insertion slot on the frame, rotate the worm to drive the worm wheel, and then rotate the bidirectional screw to drive the two L-shaped plugs to move towards each other, so that the L-shaped plugs are inserted into the locking slot;

[0018] c. Then install the fixing column and the connecting column by using No. 2 bolts;

[0019] d. Then, use the insertion rod to pass through one side of the docking claw, and then pass the insertion rod through the installation hole on the curtain wall body;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By using the plug rod to pass through the installation holes of the docking claws and the curtain wall body respectively, the connecting rings of different lengths can be replaced according to the actual situation to limit the curtain wall body. In the process of plugging, the limit blocks at the bottom and top of the plug rod extend into the receiving groove through the cooperation of the spring and the telescopic column to lock the plug rod and enhance the connection stability.

[0023] 2. When the curtain wall body needs to be replaced, a special tool is used to pass through the through hole and press down the limit block in the receiving groove to disengage the limit block from the receiving groove and remove the limit ring, so as to facilitate the replacement of the curtain wall body, enhance practicality, and improve the replacement efficiency of the curtain wall body. By arranging the first sealing gasket and the second sealing gasket on the plug rod, the curtain wall body is protected and damage to the curtain wall body during the clamping installation process is avoided as much as possible.

[0024] 3. By opening a plug-in slot on one side of the frame, the connecting column is inserted into the plug-in slot. The staff uses a special hand wheel and a protrusion that matches the key slot at the hand wheel to make the protrusion plug into the key slot, which is convenient for rotating the worm. The worm gear is then driven to rotate by rotating the worm, and the two-way screw is then driven by the worm gear to rotate, so that the two L-shaped plugs move toward each other and are inserted into the locking slots on both sides of the connecting column to lock and fix the connecting column, thereby improving the installation efficiency of the connecting column.

[0025] 4. An installation groove is provided at the side end of the fixed column. By inserting the splicing claw into the installation groove, a threaded hole is provided at the side end of the splicing claw. By using a first bolt to pass through one side of the fixed column and the threaded hole and threadedly connecting with the fixed column, the splicing claw is fixed, making the splicing claw easy to be disassembled and replaced individually, enhancing the connectivity. By providing a reinforcing arc rod at the side end of the splicing claw, the supporting strength of the splicing claw is enhanced, and the service life is prolonged.

[0026] 5. Ventilation holes are provided on both sides of the frame outside the curtain wall main body, facilitating the circulation of external air and internal air. A dust-proof net is provided at the ventilation holes to prevent external dust from flowing into the room through the ventilation holes as much as possible. By providing a sliding rod and a sliding groove, it plays a guiding and supporting role in the movement of the L-shaped insertion block, improving the movement stability. A sealing plug is provided in the placement groove to prevent external dust and rainwater from flowing into the receiving groove as much as possible, protecting the spring. By providing a anti-loss rope, the loss of the sealing plug is avoided as much as possible, enhancing the practicability. BRIEF DESCRIPTION OF THE DRAWINGS
