What are the requirements for foam board construction?
Release time: 2018/10/24 11:45:59
Foam boards are widely used in modern construction projects, such as the application in building insulation engineering, which can play a very good thermal insulation effect. However, the foam board construction requirements are relatively high, so that the foam board can play an effective role. So, what are the requirements for foam board construction ? Attention should be paid to the treatment of the wall, the detection of the foam board, the protection of the project, the technique of laying the foam board, etc., to ensure that the laying of the foam board is smooth and firm, and it can play an effective role in thermal insulation.
1. Before the construction of the foam board, the outer wall must be treated and kept clean and free of dirt, mud, dust, etc., so as not to affect the bonding effect of the foam board.
2. The base wall should be kept flat and strong, otherwise, it may affect the firmness of the foam board bonding.
3. When the foam board is constructed in summer, it is necessary to take sun protection measures to avoid direct sunlight on the construction layer, and the temperature during winter construction is not lower than zero, so as not to adversely affect the construction quality of the foam board.
4. In the rainy season construction, it is necessary to take waterproof measures and pay attention to the protection of the construction wall, so as to avoid rain erosion affecting the construction quality of the foam board.
5. Before construction, the performance of the foam board should be tested and re-inspected. The re-inspection should be checked by sampling. Generally, the density, age, thermal conductivity, bond strength, mechanical properties and corrosion resistance of the foam board are generally checked to ensure the foam. The performance of the board is stable and can meet the needs of thermal insulation engineering.
6. The thickness of the foam board must comply with the relevant provisions of China's wall design. It is necessary to ensure that the bonding between the foam board and each structural layer is strong. The bonding strength and connection method must also comply with relevant national regulations, so as to ensure the quality of thermal insulation construction. .
7. The sticking of the foam board should start from the detail nodes and the yin and yang corners to the middle. During construction, it is required to control the straightness of all the yin and yang corners of the building's outer wall along the full-height line. Use the ink fountain to make the bottom horizontal line in advance. And control lines to ensure horizontal paving. The paving within the section is from top to bottom.
8. When pasting, the board seams should be squeezed tightly. Adjacent boards should be flush. Control the gap between boards should not be greater than 2mm, and the height difference between boards should not be greater than 1.5mm. If the gap between boards is greater than 2mm, use extruded boards. The strips are filled with gaps. The planks cannot be bonded with mortar or adhesive. The flatness difference between the planks> 1.5mm is smoothed with wood files, coarse sandpaper or abrasive wheels on the construction surface.
9. Cut the foam board according to the size that has been arranged in advance, and overlap the vertical staggers from the corners. The corners are required to be straight and complete along the full height of the building.
In the construction of foam boards, there are many things that people need to pay attention to. It is necessary to create good construction conditions and master the construction techniques so as to ensure the construction quality of foam boards. Linyi Jinshun Foam is a Linyi foam board manufacturer . The foam board supply is stable and has a wide range of applications. People pay attention to the correct construction and can play a good role.
