Glass curtain wall construction practices and construction techniques

This project glass curtain wall project by the professional curtain wall company production and installation, here only introduce the general practice and requirements of the glass curtain wall

1. Basic requirements

(1) operating conditions

1) should be prepared for the curtain wall construction design, and strictly in accordance with the sequence of the design of the construction organization of the construction.

2)Curtain wall should be started after the construction of the main structure. For high-rise building curtain wall, the real needs of the schedule, should be under the premise of ensuring quality and safety, according to the construction organization design along the high section construction. In three-dimensional intersection with the upper structure of the construction of the curtain wall, the structure of the construction layer below and above the construction of the curtain wall, must take reliable protective measures.

3) curtain wall construction, the original main structure of the construction of the external scaffolding should be retained, and according to the requirements of the curtain wall construction of the necessary demolition (scaffolding from the main structure of the inner layer of not less than 300mm). Such as the use of hanging baskets to install the curtain wall, the basket must be safe and reliable

4) curtain wall construction, should be equipped with the necessary safe and reliable lifting and hoisting tools and equipment.

5)When the decoration sub-projects will cause pollution or damage to the curtain wall, the project should be arranged before the construction of curtain wall construction, or the curtain wall should take reliable protection measures.

6)Should not be in the windy and rainy climate for the construction of the curtain wall. When the temperature is lower than -5 ℃ shall not carry out glass installation, should not be carried out in the rain sealant construction.

7)Should be in the main structure of the construction control and check the fixed curtain wall of each floor (roof) elevation, side line dimensions and embedded parts position deviation, and before the construction of the curtain wall should be checked and measured. When the deviation of structural side line size is too big, necessary corrections should be made to the structure first; when the deviation of the position of the embedded parts is too big, the pitch of the frame should be adjusted or the connection between the connecting parts and the main structure should be modified.

(2)Curtain wall installation

1)Instruments and tools such as (laser) latitude and longitude, level, line hammer should be used to measure the center position of the connection point of frame material and main structure layer by layer on the main structure, and the permissible deviation of the position of the three directions of X, y and Z axes should be ±1.0mm.

2)For the component curtain wall, such as the glass is toughened glass, insulating glass, etc., the site should be adjusted in advance to ensure that the glass can be cut. Can not cut the glass, the actual size of the glass should be checked in advance, such as inconsistent with the design dimensions, should be adjusted to the center of the connection point between the frame material and the main structure. Or the glass can be customized according to the actual installation position (size) of the frame material.

3)Fix the connectors according to the measured center position of the connection point to ensure firmness.

4)Installation of unit-type curtain wall should be carried out from bottom to top. Component type curtain wall frame material should be installed from top to bottom.

5)When the component curtain wall framing or unit curtain wall units and connecting pieces connected, the entire curtain wall should be checked and corrected, and then the connecting pieces and the main structure (including anchoring with expansion bolts) of the embedded parts welded.

6) unit curtain wall gap with V and W-shaped or other type of adhesive tape sealing, embedded filling, not to be missed.

7)Component curtain wall should be required by the design drawings for glass installation. Glass installation in place, should be used in a timely manner rubber strips and other inlay materials and frames fixed, not temporary fixed or floating pendulum.

8) glass perimeter of each side of the rubber strip should be a single whole material, in the glass corner are disconnected, the rubber strip type should be error-free, inlay leveling.

9)Rubber strips outside the sealant, the species should be correct (coated glass preservation surface is strictly prohibited to use acetate-type organic silicone adhesive), should be dense and uniform, no leakage, the appearance of flat

10)Unit-type curtain wall of the gap between the units, components of the curtain wall of the gap between the frame material, the frame material and the gap between the glass, as well as all other gaps, should be required according to the design drawings Be left enough.

11)The gap between the units of unit-type curtain wall and the gap between the glass of the hidden curtain wall should be installed according to the design requirements, to maintain uniformity.

12)Galvanized connectors should be removed after welding flux skin, galvanized surface damage at the weld surface should be brushed with two anti-rust paint. All materials in contact with aluminum alloy profiles (including Lianyungang junction) and construction measures, should be in line with the design drawings, shall not be contact corrosion, and shall not be in direct contact with cement mortar and other materials.

13) should be in accordance with the node construction requirements specified in the design drawings, the curtain wall lightning protection grounding, and all structural nodes (including fire nodes) and closing node installation and construction.

14)The detergent for cleaning the curtain wall shall be tested, and shall have no erosion effect on the aluminum alloy profile plating preservation, glass and sealing tape, and shall be rinsed out in time.

2. Installation process of unit-type curtain wall

The on-site installation process of unit-type curtain wall is as follows:

Measuring and placing lines→Checking the position of pre-embedded T-slot→Threading in the screw→Fixing the bull's leg→Finding the bull's leg to be straight→Finding the bull's leg to be straight→Welding the bull's leg→Hanging the V-shaped and W-shaped tape roughly→Lifting up the curtain wall and padding the damping pads→Tightening the screws→Adjusting the flatness and straightness of the curtain wall→Corking the hot compression joint windproof tape→Announcing the curtain wall. Hot crimping windproof tape → Installation of indoor window sill plate, internal buckling plate → Filling and beams, columns between the fire insulation material.

3. Component curtain wall installation process

1) open frame glass curtain wall installation process

Inspection, sorting and stacking of curtain wall components→measuring and placing of lines→main and secondary keel assembly→floor fasteners installation→installation of the main keel (solid rod) and leveling and adjustment→installation of secondary keel (crossbar)→installation of heat preservation galvanized steel→welding and riveting screws on galvanized steel→installation of inter-story protection Mineral wool → installation of floor closed galvanized plate → installation of single glass window sealing strip, card → installation of single glass → installation of double insulating glass sealing strip, card → installation of double insulating glass → installation of side pressure plate → inlay sealing strip → installation of glass curtain wall aluminum cover strips → cleaning → acceptance, handover.
