[China Glass Net] The point-type glass curtain wall is the late show in the installation of the glass curtain wall. Because of its uniqueness, there are so many fans. Xiaobian talks about some of the knowledge related to the point glass curtain wall.
A. Form composition:
Point glass curtain walls are a new way of supporting. The point-type glass curtain wall, which is called the metal-supported structure point-type glass curtain wall, has developed rapidly in the city.
According to the different ways of the support structure, the point glass curtain wall can be divided into the following types:
Metal support structure point glass curtain wall. This is a form that is currently used more. It is made of a metal material as a supporting structure system, and the surface glass is firmly fixed on it through metal connecting members and fasteners, which is very safe and reliable. Taking full advantage of the flexibility of the metal structure to meet the needs of architectural modeling, one can clearly see the entire structural system of the supporting glass through the glass. The crystal clear and transparent metal structure, the embodiment of "beauty" and "force". Enhance the effect of "virtual" and "real" contrast. Point glass curtain walls are a new way of supporting. The point-type glass curtain wall, which is called the metal-supported structure point-type glass curtain wall, has developed rapidly in the city.
B. Point glass curtain wall:
(1), all-glass structure point glass curtain wall. It connects the glass support structure (glass rib) with the face glass through metal connectors and fasteners to form a building envelope. The construction is simple and cost-effective, and the glass surface and ribs form an open view, which makes people pleasing to the eye. The indoor and outdoor spaces of the building achieve a greater degree of visual blending.
(2), pull rod (cable) structure point type glass curtain wall. It adopts a stainless steel tie rod or a support structure for the curtain wall by using a cable corresponding to the glass split joint. The glass is secured thereto by a metal connector. The precision of the full-service machining in the building makes the components all the tension members. Therefore, the construction should be pre-stressed. This softening can reduce the breakage rate of the glass during vibration.
C. Components:
(1) Support system. The support system transmits the various loads received by the cover glass directly to the building's main structure. Therefore, it is the main force-bearing component, generally according to the load bearing size and architectural shape, such as glass ribs, stainless steel columns, aluminum profile columns or steel shelves with appropriate anti-corrosion and anti-surface treatment. Steel columns and stainless steel rods (cables).
(2), metal connectors. The metal connector includes a fixing member (commonly referred to as a claw seat and a paw) and a fastener. The fasteners are usually cast from stainless steel and the fasteners are stainless steel machined parts. In view of metal compatibility, the jaws must be of the same material as the support system or mechanically fixed. Metal connectors are the essence of architectural point technology. It fixes the face glass on the support structure not only creates additional stress on the edge of the glass hole, but also allows a small amount of displacement to adjust the construction error caused by the building installation, and also has shock absorption measures to improve the seismic resistance, so the design considerations The factors are multifaceted. The metal connector also produces a remarkable decorative effect, so in addition to meeting the functional requirements, it also has a beautiful design and fine processing, which plays the role of “finishing the finishing touchâ€.
(3), glass. The glass used in the construction of the point-type glass curtain wall reduces the strength of the glass at the edge of the hole by about 30%. Therefore, the point-type glass curtain wall must be made of high-strength tempered glass (the impact strength of the tempered glass is float glass 3) -5 times, the bending strength is 2-5 times that of float glass.) Another important characteristic of tempered glass is that it is safe to use and produces fine fragments without sharp angle when it is damaged by large external force (commonly known as "glass rain" "), not easy to hurt people.
D. Distinguished from tradition:
(1) Structure: The point-type glass curtain wall is a brand-new architectural space structure system which combines modern structural technology and glass technology designed by computer. The curtain wall skeleton is mainly made of seamless steel pipe and stainless steel rod (or re-laso). It is composed of stainless steel claw members, and its face glass is perforated at the corner position and connected to the all-glass curtain wall of the support structure by metal connectors. The general glass curtain wall is mostly the structure of the plane frame type and the vertical rod force system.
(2), glass fixed form: the glass of the point glass curtain wall is reliably fixed by the stainless steel claw piece through the pre-drilled hole on the glass, while the general glass curtain wall, such as the full implicit or semi-implicit type, is made of structural adhesive. Bonding is fixed to the frame.
(3) Component processing: The main metal components of the point glass curtain wall require precision machining of the car drilling and stamping machine tools, and batch production in the factory. The site installation precision is high and the quality is good. The aluminum alloy of the general glass curtain wall is mostly made by the electric motor on the construction site, and the processing is slightly rough, the precision is not high, and the performance is low.
(4), glass varieties and specifications: the glass used in the point glass curtain wall is mostly low-radiation or white-tempered insulating glass, and has a certain effect on solving urban light pollution, the glass specification limit is not so strict. In general, glass curtain walls often use coated reflective glass, and the glass specifications are generally small.
