After the installation of steel mesh, it can be said that there are many advantages and advantages in use. Therefore, the reinforcement mesh now has a good prospect. Steel mesh is a kind of steel mesh with longitudinal reinforcement and transverse reinforcement arranged at a certain distance and at right angles, and all cross welding points are welded together. However, before the reinforcement mesh is put into use, it must go through the installation procedure. Therefore, the installation method will determine the use of good or bad.
At present, there are three commonly used installation methods of steel mesh: one is direct welding installation, one is using installation clamp, the other is using angle steel embedded installation. But these three installation methods have their own advantages and disadvantages.
1、 Fixed welding method
This method is a common method to install steel mesh. During installation, there are four welding points around the reinforcement mesh. As long as these four welding points are welded firmly, it can be put into use basically. However, if the steel mesh needs to be weighed frequently, it is necessary to find several more welding points on the basis of the welding of the four welding points.
2、 Fixing method of mounting frame
This method of installation of steel mesh is also more common, but the general method will be used in the steel mesh bearing mechanical equipment. The number of open welding at the intersection of building steel mesh reinforcement shall not exceed 1% of the total number of crossing points of the whole mesh. Moreover, the number of open welding points on any steel bar shall not exceed half of the total number of crossing points on the steel bar. No open welding is allowed at the intersection of the outermost reinforcement of the mesh. Using this installation method, first of all, there is a more prominent advantage is that the installation and construction is relatively simple, and then if there is a demand for disassembly, it will be more convenient.
3、 Angle steel inlay fixing method
For such installation method, if the reinforcement mesh is installed on the pipe trench as the trench cover plate, it is a very good installation construction method. During the construction, during the installation, two angles are fixed on both sides of the trench, and then the steel mesh is embedded on the two angles. The use of this installation method can be said to be completely independent, and the welding method can not be used any more, and the fixing clip can be used for installation.
The above several installation methods of steel mesh, first of all, different installation methods should be applied to different installation construction, and another point is that each installation method has its own advantages and disadvantages in each construction. The appearance of welded steel mesh is of great significance in improving construction efficiency, structural quality, safety and reliability, and changing the traditional construction method. It can be used for reinforcement of reinforced concrete structure and ordinary reinforcement of prestressed concrete structure. First of all, when there is a long-term construction method, we should avoid the short-term installation.
