Everyone knows GRC It is a kind of chemical fiber concrete polymer material with alkali resistant glass fiber as the raw material for improvement and mixed mortar as the base material. It is also a kind of cement component for decorative design of building details. So there must be relevant standards and regulations for installation related to engineering buildings. Otherwise, improper operation may lead to life safety and other unnecessary damage.
Then go on Baotou GRC Tell everyone about the proper installation method of GRC prefabricated components?
First of all, we should remind you that the net weight of larger GRC prefabricated components is relatively heavy, which is very easy to fall out. Therefore, we can carry out temporary structural reinforcement according to the way of setting support points to facilitate the construction of the project.
1、 Proper installation method of GRC prefabricated components:
1. First, snap out the positioning line (center line or border line) according to the engineering drawing at the location where GRC prefabricated components are to be installed
2. Then install GRC prefabricated components with laser cutting specifications according to the engineering drawings. When laser cutting GRC prefabricated components, how to master the size of GRC prefabricated components? First of all, we should ensure that the stitching width is appropriate.
3. When pasting GRC prefabricated components, the alkali resistant mesh cloth can be unwrapped and immediately pasted. High quality plastering mortar can be applied to carry out adhesion according to the method of full layer pasting, and cement mortar can be squeezed from GRC prefabricated components vigorously. The adhesive joint shall be hooked up at the same time, and the total width shall be less than 3mm, so as to maintain the smoothness and cleaning of the adhesive joint.
4. The installation of GRC prefabricated components shall be carried out. The size of GRC prefabricated components shall be measured first, and the trial assembly shall be carried out on the flat ground first. If the gap between GRC components is less than 3mm, high-quality plastering mortar can be used for bonding. Pay attention to the uniformity of plastering mortar.
5. Check the assembled GRC prefabricated components, and polish the plastering mortar at the interface with sanding paper. After the plastering mortar is dry, the GRC prefabricated component crack resistant fiber special adhesive can be used for further pasting.
2、 Product quality standards for installation of GRC prefabricated components:
1. Prefabricated components are installed horizontally, vertically and vertically, generally released, and the relief pattern is checked in detail. The curve is smooth and smooth, and the surface of prefabricated components is free of pollution and damage.
2. The installation connection points of prefabricated components shall be aligned accurately to avoid the deformation of prefabricated components due to the installation ground stress caused by the strong torsion in place due to the displacement of embedded parts.
3. Precast member nodes must be connected in time and cannot be ignored. The screw connection must be tight and tight.
4. Prefabricated component connectors shall be smooth, and the joints shall be less than 11mm.
5. The longitudinal prefabricated members shall prevent the upper prefabricated members from being stacked on the bottom prefabricated members layer by layer, and each section of prefabricated members shall be independently suspended on the wall.
6. After the installation of prefabricated components, the dust and dirt on the surface shall be cleaned up from top to bottom, the joints shall be rounded, polished and leveled.
Above are the five processes and product quality standards for the proper installation of GRC prefabricated components that Baotou GRC has sorted out for everyone today. If there are other installation methods, you are warmly welcome to fill~
