Floor installation and maintenance knowledge

No matter what kind of floor, suspension installation method: well-known. Even if the rails are left expansion joints. If the floor and floor are firmly nailed to death, affected by the climate, the floor and floor materials are different, the coefficient of retraction must be different, and cracking and deformation will occur. Bamboo flooring adopts scientific suspension installation method, which is in line with the physical characteristics of bamboo flooring. It takes full account of the expansion factors of cement floor and bamboo floor, and uses bamboo flooring to spliced ​​together on four sides, and does not bond to the ground. Certain expansion joints (safety joints) are covered with the foot above, adhere to the overall appearance of the floor, and give the bamboo floor space to shrink, the bamboo floor will not bend. Using suspension installation method, no need to fight dragon skeletons, do not lay flat panels, do not glue, do not hit nails, do not sand, do not paint (each bamboo floor has been sealed with imported UV paint on all sides, the appearance has been formed Sturdy wear-resistant layer) saves time, labor, material, and money (Paving costs only one-third of the wood floor paving costs) Disassembly, preparation before installation 1 leveling the ground, with grout Smooth and dry. 2 Use asphalt to paint the ground 12 to enlighten and dry it. 3 Use 3mm thick foam board with plastic sheet to lay the floor. It is required to be flat, non-overlapping and non-crease. 4 ready to use 1.21.2cm fir bar number. Second, install a good amount of bamboo flooring size, reasonable materials. All cut-off plates must be sealed with varnish to prevent moisture. 2 When laying bamboo flooring, put fir sticks (1.21.2cm) at the roots of the surrounding walls and begin to lay the first piece vertically.

Rolling Machine

Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
