Second, the resistance plate installation method
First, the embedded installation method is as follows:
1. The thickness and thermal expansion and contraction of the root plate are different from those of the support frame, and sufficient embedment is reserved for wind pressure and snow pressure loads. Generally, the edge of the plate extends into the fixing frame for more than 25mm, so it is required to install at least two ribs in the fixing area, and the thermal expansion coefficient is 0.065mm/m. ..
2. According to the local climatic conditions and the temperature during installation, determine the reserved distance of thermal expansion between plates. Usually, when installing in summer, the reserved distance can be less, and when installing in winter, the reserved space should be larger. For embedded installation, the length of the board should not be too long, because the longer the length, the greater the thermal expansion length.
3. Be realistic in installation: at the end of installation, the plate can still move slightly on the bracket without affecting the combination of the filling material or the bracket. Therefore, the filling material needs to have certain adhesion and flexibility.
Type II: The screw installation method is as follows:
1. When installing screws or rivets through holes, the hole diameter of the plate must be 50% larger than that of the screws or rivets to prevent the plate from moving when it expands when heated and contracts when cooled. It is forbidden to directly open holes, fix or rivet at the same time, and no space can be reserved for thermal expansion and cold contraction.
2. When drilling holes in the board, the spacing between holes should not be too large or too small. If the spacing is large, the cumulative thermal expansion length will be large, and if the reserved space is not enough, the movement of the plate will be seriously restricted if the spacing is small. The stress is too concentrated, and if it is allowed to bend outward during thermal expansion, part of the stress can be offset.
3. Usually, when drilling holes in the plate, the hole spacing is 50CM, and the distance between the hole and the edge of the plate is suggested to be above 3-5CM.
4. The rivet head diameter should be larger than the handle diameter by two parts, and gaskets or washers should be added to avoid damaging the plate under the high pressure produced locally.
5. Screw should be tightened too tightly to avoid fracture of bone plate, and it is best to allow slight displacement of bone plate after fixation.
6. PVC gaskets or waterproof tapes containing asphalt components should not be used, because the chemical additives precipitated from them will cause chemical corrosion to the plate, resulting in cracks or even cracks on the surface of the plate.
7. When cold bending, avoid fixing the bent part with screws.
8. All pores should be filled with neutral silicone structural sealant to prevent the cleaner from infiltrating into the edge and affecting the quality of the plate.
What I recommend to you today is the difference between flame-retardant cables and fire-resistant cables. In addition, we also introduce the classification of fire-resistant cables according to grades. Therefore, firstly, the flame-retardant cable, as its name implies, has good thermal stability and will not cause the fire to spread, but it can control the fire risk. However, compared with fire-resistant cables, they still have some special features and are suitable for different places. When buying, everyone should choose the size and specifications according to their own differences and the advice of professionals. I believe this will achieve the final satisfactory effect and purpose.
