Lifting and installation methods of machine-made rock wool panels

Machine-made rock wool panel is a building material with fireproof and heat-insulating properties, and is often used in partition walls and ceilings of buildings. The following are its common installation methods:

1. Preparation

Tool preparation

Choose suitable lifting equipment, such as a crane or electric hoist. The lifting capacity of the crane should be determined according to the weight of the rock wool board and the number of hoisting. For small-scale machine-made rock wool panel installation projects, electric hoists are a more flexible choice. At the same time, prepare the ropes for lifting. It is recommended to use nylon ropes with high strength and good flexibility. The diameter should be able to withstand the weight of the rock wool board to prevent the rope from breaking during the lifting process.

It is also necessary to prepare clamps for fixing the rock wool panels, such as metal clamps, which can firmly clamp the edges of the rock wool board to ensure that the rock wool boards will not slip during the lifting process.

Staff preparation

Arrange professional lifting operators, who must hold relevant operating certificates and be familiar with the operating procedures of the lifting equipment. At the same time, auxiliary personnel are also required to assist in the placement of the rock wool panels on the ground and at the installation location.

Site preparation

Clean the hoisting site to ensure that the site is flat and free of obstacles. Set up warning signs in the hoisting area to prevent unauthorized personnel from entering. For outdoor hoisting, pay attention to weather conditions and avoid hoisting operations in severe weather such as strong winds and heavy rain.

2. Bundling and fixing of rock wool panels

Bundling method

Bundle the machine-made rock wool panel according to a certain number and specifications. For thinner rock wool boards (such as those with a thickness of 50-100mm), bundle them in groups of 10-15 pieces. When bundling, ensure that the edges of the rock wool panels are aligned, and use nylon ropes to cross-bundle the length and width of the rock wool boards. The knots must be firm and cannot damage the surface of the rock wool sandwich panel.

Fixing measures

Install metal clamps on the edges of the rock wool panels, and the spacing between the clamps is generally 1-1.5m. The clamps must clamp the rock wool boards and be firmly connected to the hoisting ropes. For large rock wool sandwich panels (length or width exceeding 2m), a clamp can be added in the middle to ensure the stability of the rock wool board during the lifting process.

3. Lifting operation

Lifting process

After connecting the lifting rope to the clamp that fixes the rock wool panel, start the lifting equipment. Lift slowly to keep the rock wool sadnwich board balanced. Operators should pay close attention to the state of the rock wool panel.s Once the rock wool panel is found to be tilted or swaying, the lifting should be stopped immediately and the position of the rock wool panel should be adjusted to restore its balance.

Hoisting process

During the lifting process, the rock wool sandwich panel should maintain a certain height to avoid collision with surrounding objects. For the lifting of rock wool boards in multi-story buildings, ensure that the rock wool panels can pass through the openings or windows on each floor smoothly. If it is necessary to change the direction of the rock wool board during the lifting process, operate the lifting equipment extremely carefully and turn slowly.

4. Base treatment

Wall base

For the installation of machine-made rock wool boards on the wall, ensure that the wall is flat and dry. If the wall surface is uneven, cement mortar needs to be used for leveling. For oil stains, dust and other impurities on the wall, it should be thoroughly cleaned. If the flatness error of the wall exceeds 5mm, it needs to be repaired first, otherwise it will affect the installation effect and thermal insulation performance of the rock wool board.

Roof base

The roof base should be waterproofed, and the slope of the roof should meet the design requirements. Before installing the rock wool panel, check whether the drainage system of the roof is unobstructed. If there is water accumulation on the roof, the water accumulation problem should be solved first, because the water accumulation will cause the rock wool panel to be damp and reduce its thermal insulation and heat insulation performance.

5. Installation and fixation

Bonding method

Use a special thermal insulation adhesive to stick the rock wool panels to the surface of the base. Before sticking, apply the adhesive evenly on the back of the rock wool panel, and the thickness of the application is generally 3-5mm. The application area of ​​the adhesive should reach 40%-60% of the area of ​​the rock wool board. After sticking the rock wool panel on the base, use special tools to compact the rock wool board to ensure that the rock wool board fits tightly with the base. Excess adhesive can be squeezed from the center of the rock wool board to the edge to prevent hollowing.

Anchoring method

When the thickness of the rock wool board is large (such as more than 100mm) or the installation height is high, in addition to bonding, it is also necessary to use anchoring to fix it. Use special rock wool board anchors, generally plastic expansion anchors. The length of the anchor should be determined according to the thickness of the rock wool board and the condition of the base. Generally, it should penetrate the rock wool board and penetrate at least 30mm into the base wall. The spacing of the anchors is generally 3-5 per square meter. The edges and corners of the rock wool board should be appropriately encrypted, and the spacing can be reduced to 300-500mm. When installing the anchors, use an electric drill to drill holes in the rock wool board and the base, insert the anchors into the holes and tighten them to firmly fix the rock wool board on the base.

6. Splicing treatment

Panel seam treatment

During the installation of machine-made rock wool sandwich boards, gaps will appear between the boards. For horizontal gaps, the gap width should be uniform, generally controlled at 3-5mm. For vertical gaps, special sealants can be used to fill them. When filling the sealant, apply the sealant evenly in the gap, and ensure that the sealant is tightly combined with the edge of the rock wool board to prevent the penetration of air and moisture.

Corner treatment

At the corners of the wall or roof, special attention should be paid to the installation of rock wool panels. The rock wool sandwich panel can be cut into appropriate angles for splicing. For the insulation of the corners, the "L"-shaped rock wool panel splicing method is usually adopted. The rock wool board on one side is installed first, and then the other side is installed to ensure that the rock wool panels at the corner is tightly fitted without leaving gaps. After the splicing is completed, metal corner guards can be used at the corners for reinforcement to enhance the impact resistance and deformation resistance of the rock wool panel at the corners.

7. Surface protection and finishing work

Surface protection

After the installation, if the rock wool panel is used for exterior wall insulation, it is necessary to apply anti-cracking mortar on the surface of the rock wool panel. The thickness of the anti-cracking mortar is generally 3-5mm. Before the anti-cracking mortar is completely dry, the alkali-resistant mesh cloth is embedded in it. The alkali-resistant mesh cloth should completely cover the surface of the rock wool board and be flat and wrinkle-free. This can effectively prevent cracks on the surface of the rock wool board and improve its durability.

Cleaning and inspection

After the installation is completed, the construction site should be cleaned to remove the debris, adhesive and sealant residues of the rock wool panel. At the same time, the installed rock wool sandwich panel should be inspected, including the fixing of the rock wool board, the sealing of the board seams, the quality of the surface protection layer, etc. If problems are found, they should be repaired in time to ensure that the installation quality of the rock wool board meets the requirements.
