The term "reflection glass curtainwall" refers to a building envelope structure or a decorative structure in which a supporting structure system can have a certain displacement capacity with respect to the main structure and does not share the role of the main structure. There are two kinds of single and double glass walls. Glass curtain wall is a beautiful and novel building wall decoration method, which is a distinctive feature of modern high-rise buildings. According to the Fatal Light Awareness Program (FLAP) statistics from the Bird Protection Volunteer Organization in 2013, only 1 to 9 million migratory birds die in these glass curtain walls every year in Toronto. Glass curtain wall is one of the most commonly used materials in many modern high-rise buildings. It is composed of mirror glass and ordinary glass, combining organic functions such as modern architectural aesthetics, fashion and atmosphere, but also presents a dynamic with the changes of light. nice. The glass curtain wall is so superior. Then do you know about the price of glass curtain walls? What is the construction plan of the glass curtain wall ? Then let's take a look at the price of glass curtain walls and the construction plan of glass curtain walls .
Glass curtain wall
Glass curtain wall refers to a building envelope or decoration structure that is composed of a support structure system and glass and can have a certain displacement ability relative to the main structure, but does not share the role of the main structure. Usually it has a single layer and a double layer. The points. The combination of mirror glass and ordinary glass in the glass curtain wall is beautiful and novel. It is a distinctive feature of high-rise buildings in the new era.
Glass curtain wall features
The glass curtain wall is used as the mirror glass of the exterior wall of the building. It is made by adding some trace elements such as Fe, Ni, Co, Se and so on to the composition of the float glass. It can effectively absorb infrared rays, reduce the solar radiation entering the room, soften the visual effect, reduce the indoor temperature, and achieve the effect of warm winter and cool summer. In addition, it reflects light and transmits light.
The glass curtain wall is a new type of wall, light and beautiful, not easy to pollute and save energy. The outer side of the outer glass is coated with a colored metal coating, which looks like a mirror from the outside and reflects the sky and the surrounding environment. When the light changes, the reflected image is colorful and changes. It is very interesting. . When installed in a glass curtain wall room, it will not be exposed to strong light and the light will be softened.
Glass curtain wall price
Regarding the price of glass curtain walls, it mainly depends on the area and the type of materials you want to set. First, there are many kinds of glass curtain wall materials, such as size and profile wall thickness, and then the types of glass. The prices of insulating glass, laminated glass, coated glass, and LOW-E glass are all different. The ordinary glass curtain wall is different. The price is mostly between 850-1200 yuan.
Glass curtain wall construction plan
1. Related materials and tools to collect and prepare
Before construction, go to the construction site to collect relevant information. As there may be some changes in the construction of the civil works, the actual size may not always conform to the design drawings. All-glass curtain walls have high requirements on the size of civil structures. Therefore, before the design, you must go to the site to measure, obtain first-hand data, and then you can draw a practical and feasible wall partition diagram according to the requirements of the owner. For parts with door entrances and exits, it must also cooperate with the units that make automatic revolving doors and full glass doors so that the glass curtain walls have reliable closing on the doors and doors, and also the requirements for the installation and maintenance of automatic revolving doors. The tools to be used should also be prepared in advance.
2. Design and construction plan is determined
In the design separation of glass curtain walls, in addition to considering the uniform appearance of the appearance, attention should also be paid to minimizing the specifications and models of the glass. As the outdoor designs of all types of buildings are not the same, it is necessary to pay attention to coordinating the overall construction sequence and progress for projects such as outdoor canopies and driving ramps to prevent the construction of other outdoor facilities from affecting crane walking and glass curtain walls. installation. Before the formal construction, the construction site should also be leveled and filled, and the site should be cleaned to ensure that the crane can walk smoothly.
Glass curtain wall construction practices and construction techniques
1, curtain wall installation
1) The use of (laser) theodolites, spirit levels, line hammers and other instrumental tools shall be used to measure the center position of the connection points between the frame material and the main structure one by one on the main structure. The permissible deviations in the three directions of the X, y and Z axes are: ±1.0mm.
2) For component-type curtain walls, if the glass is tempered glass, hollow glass or other glass that cannot be cut on the spot, the actual size of the glass should be inspected in advance. If it is inconsistent with the design size, the center of the connection point between the frame and the main structure should be adjusted. Or you can customize the glass according to the actual installation position (size) of the frame material.
3) Fix the fastener by the measured center point of the connection point to ensure firmness.
4) The unit curtain wall installation should be carried out from the bottom up. Component curtain wall frame should be installed from top to bottom.
5) After the elements of the curtain wall frame or unit curtain wall are connected with the connecting elements, the whole curtain wall shall be inspected and corrected, and the joints shall be welded to the embedded structure of the main structure (including the anchor bolts). .
6) The gap of the unitary curtain wall is sealed with V and W-shaped or other types of rubber strips.
7) The elemental curtain wall shall be installed in accordance with the design drawings. After the glass is installed in place, it should be fixed with rubber strips and other embedded materials in time with the frame, and shall not be temporarily fixed or clearly suspended.
8) The rubber strips on each side of the glass should be a single solid material, and they should be broken at the glass corners. The rubber strip type should be correct and the inserts should be flat.
9) The sealant applied on the outside of the rubber strip shall be correct (the acetic acid-type silicone adhesive shall not be used on the rhodium plated surface of the coated glass). It shall be dense and even, and shall not be omitted. The appearance shall be smooth.
10) The gaps between the elements of the unitary curtain wall, the gaps between the frame materials of the elemental curtain wall, the gap between the frame material and the glass, and all other gaps shall be sufficient as required by the design drawings.
11) The gaps between the elements of the unit curtain wall and the gaps between the glass of the hidden curtain wall shall be installed according to the design requirements and shall remain uniform.
12) After the welding of galvanized joints, the coating shall be removed and the surface of the weld where the galvanized surface is damaged shall be brushed with two antirust paints. All materials in contact with aluminum alloy profiles (including Lianyungang joints) and construction measures shall comply with the design drawings, shall not be subject to contact corrosion, and shall not be in direct contact with materials such as cement mortar.
13) The lightning protection grounding of the curtain wall, and the installation and construction of all structural nodes (including fireproof nodes) and shutoff nodes shall be carried out in accordance with the requirements of the node structure specified in the design drawings.
14) The detergent for cleaning the curtain wall should be inspected, and it should not be corroded by aluminum alloy profile rhodium, glass and sealant, and it should be rinsed in time.
2. Installation process of unitary curtain wall
The on-site installation process of the united curtain wall is as follows:
Measure the payoff line → check the location of the embedded T-slot → penetrate the screw → fix the cow's leg → correct the cow's leg → correct alignment of the bull's leg → solder the leg of the cow's leg → hang the V-shaped and W-shaped tape roughly → lift the curtain wall and pad Damping pad → tightening screws → adjust the straightness of the curtain wall → insert the hot-pressed windbreak → install the interior window plate, the inner buckle plate → fill the fireproof and thermal insulation material between the beam and the column.
3, the installation process of the component curtain wall
1) Installation process of clear glass curtain wall
Inspection, sorting and stacking of curtain wall components → measuring payoffs → primary and secondary keel assembly → installation of floor fasteners → installation of main keel (strand) and copying, adjustment → installation of secondary keel (crossbar) → installation of heat-insulated galvanized steel → Welding rivets on galvanized steel plate → Install interlayer protection mineral wool → Install floor closed galvanized sheet → Install single-layer glass window sealing strip, card → Install single-layer glass → Install double-layered insulating glass seal, Card → Install double layer Insulating glass → installation side pressure plate → inlaid seal → installation of glass curtain wall aluminum cover bar → cleaning → acceptance, delivery.
2) Hidden Frame Glass Curtain Wall Installation Process
Measurement of payoffs → installation of fixed bearings → installation of column rails → installation of external protective structure components → sealing of external protective structure components and disposal of the surrounding edges → treatment of fire barriers → cleaning and others.
4, no skeleton glass installation process
As the glass is long, large and heavy, a mechanized construction method is generally used in construction. That is, an electric vacuum sucker is installed on the forklift, the glass is sucked in place, the operator stands on a scaffold erected on both sides of the glass upper end, and the glass is clamped by the clamping device. The upper end is fixed and fixed, and each glass is caulked with silicone.
Editor's summary: The above is the introduction of glass curtain wall construction plan and glass curtain wall construction technology and practice. Although the production and construction technology of glass curtain wall is mature, it can ensure that all indicators of glass are in compliance with the relevant regulations of building materials, but at present The maintenance of the glass curtain wall has not received sufficient attention from the owners. Last year, Shanghai caused an accidental injury caused by the sudden breaking of the glass curtain wall of the tower. The various materials of the glass curtain wall have a certain period of use. The owner must pay attention to the replacement of the material that is about to exceed the deadline. At the same time, he must pay attention to the maintenance of the glass curtain wall during the use period. On the one hand, the material use time must be extended. Aspects can also prevent accidents.
