The width of the aluminum veneer glue seam and the width of the anti-seismic glue

Reading: The development of the city is changing with each passing day. The decoration of the curtain wall is like dressing. It is necessary to stand out in a colorful city. The novelty, safety, environmental protection and durability of the curtain wall material are bound to become the basic characteristics.

As we all know, aluminum alloy has excellent rigidity, light weight, and strong plasticity. It is convenient for aluminum veneer curtain wall manufacturers to conduct customized processing of various shapes, and attentive friends will find that aluminum curtain wallboard construction usually has 10-20mm. Wide seismic joints, what is this?

Because of the construction of metal curtain walls, there are mainly two kinds of joint processes. The first one is to leave the plastic joints, mainly aluminum alloy curtain walls are more expensive than the relative aluminum-plastic plates, so the general thickness is basically between 1.5~3.0mm, in order to increase the curtain wall. The board surface is rigid, so the manufacturer needs to carry out four-folding and welding angle processing, and at the same time at the four-folded edge, the dislocation is fixed and installed in a corner to facilitate the construction and fixing. In fact, this is the objective reason for leaving seams of aluminum veneer curtain walls, because the strength of the materials produced by the company's strong metal curtain wall manufacturers are all good. For 1200*2400mm panels, the gap control is no problem at 2mm. The subjective reason is because of the curtain wall. Staying seams is safer than seamless stitching. In general, the construction is just to fix the corners on the keel steel frame behind the backboard. Over time, wind, rain, and rain will cause the phenomenon of rust and loosening of the node screws. It is easy to cause potential safety hazards, so the gaps are glued to make the curtain wall materials stick together to form a safe and secure whole. The problem of ground settlement can also reduce the deformation of the curtain wall.

The so-called close-fitting curtain wall construction, relatively speaking, the gap is relatively small, the early aluminum-plastic plate, because it can not bend and welding, so it is all this way construction. We spread the metal curtain wall, some of which have artistic designs on the board surface, such as punching, engraving, etc. If this type of curtain wall board left seams, it will affect the overall effect of the pattern, and sometimes this kind of close fitting installation method will be adopted. There are two types of seamless close-joint nodes. One is the back panel, glued directly, and this method can only be used indoors. Another construction method is still using a steel frame keel. The joints are fixed with flat screws or rivets. At the same time, the screws also need to be baked. There is no color difference after the construction.

About the width of anti-seismic glue, and the choice of sealant:

In the foregoing, we mentioned that in some years after the completion of construction, some buildings are more or less difficult to avoid the problem of subsidence due to slight foundations. At this time, the role of 10-20mm seismic joints reserved for aluminum curtain walls is obvious, which can offset the dislocation of settlements. The gap is such that the curtain wall panels will not deform and bulge. The construction process generally uses neutral weathering glue, and can be color-matched according to the surface color, and even completely without color. Sealant life is generally more than 10 years, so the aluminum curtain wall board left a great effect!
