Detailed explanation of the construction process of roof rock wool board
I. Introduction. With the continuous development of the construction industry, the selection of roof insulation materials and construction technology are also constantly improving. As a high-efficiency thermal insulation material, rock wool board has been widely used in roof insulation projects because of its good thermal insulation performance, fire performance and environmental protection characteristics. This article will introduce the construction process of roof rock wool board in detail, including material preparation, base treatment, rock wool board laying, fixing and connection, construction of plastering layer, acceptance and maintenance, etc., in order to provide technical guidance and reference for relevant construction personnel.
2. Preparation of materials.
1.Rock wool board: select the rock wool board that meets the requirements of the specification to ensure that its quality is qualified and the specifications and dimensions meet the design requirements.
2.Special binder: choose a special rock wool board binder to ensure its adhesion performance with the rock wool board.
3.Auxiliary materials: including mesh cloth, anchors, sealants, etc., which are fully prepared according to the design requirements.
3. Grassroots treatment.
1.Clean the base layer: remove the oil, dust and other debris on the surface of the base to ensure that the base is dry, smooth, and free of sand and cracking.
2.Leveling treatment: For the uneven area of the base layer, the leveling mortar is used for leveling treatment to ensure the flatness of the base layer.
Fourth, the laying of rock wool boards.
1.Nesting planning: According to the design requirements, the nesting planning of the rock wool board is carried out, and the laying sequence and plate size are determined.
2.Laying the rock wool board: lay the rock wool board on the base layer according to the plan to ensure that the rock wool board is closely attached to the base layer and there is no gap.
3.Bonding and fixing: use a special binder to bond the rock wool board to the base layer, and at the same time use anchors to fix it to ensure that the rock wool board is stable and does not fall off.
5. Fixation and connection.
1.Anchor installation: According to the design requirements, install anchors on the rock wool board to ensure that the anchors are accurately positioned and evenly spaced.
2.Connection treatment: At the connection between the rock wool plates, special sealant is used for sealing treatment to ensure that the connection is seamless and leakage-free.
Sixth, the construction of the plastering layer.
1.Plastering mortar preparation: According to the design requirements, prepare an appropriate amount of plastering mortar to ensure that the quality of the mortar is qualified.
2.Plastering mortar construction: apply a layer of plastering mortar on the surface of the rock wool board to ensure that the mortar is evenly applied and there is no leakage.
3.Mesh cloth laying: Before the plastering mortar is dry, lay the mesh cloth to enhance the crack resistance of the plastering layer.
4.Secondary plastering: apply the plastering mortar again, so that the mesh cloth and the mortar are closely combined to form a complete plastering layer.
7. Acceptance and maintenance.
1.Quality acceptance: After the construction is completed, a comprehensive inspection of the roof rock wool board insulation project is carried out to ensure that the construction quality meets the design requirements and relevant specifications.
2.Maintenance: Regularly maintain the roof, check whether the anchors, grid cloth, etc. are in good condition, and repair them in time if there is any damage, so as to ensure the long-term stable operation of the roof rock wool board insulation project.
8. Conclusion. The construction process of roof rock wool board involves multiple links, and the construction personnel need to operate in strict accordance with the requirements of the specification. Through the detailed introduction of this article, it is believed that the relevant construction personnel have a deeper understanding of the construction process of the roof rock wool board. In the actual construction, the construction personnel should combine the actual situation of the project and flexibly use the knowledge learned to ensure the quality and effect of the roof rock wool board insulation project. At the same time, the construction unit and the supervision unit should strengthen the supervision and management of the construction process to ensure the quality and safety of the construction.
