Steel soundproof door practice - steel soundproof door production points

When making steel soundproof doors , the door leaf core should be filled with ultra-fine glass wool or rock wool, but it should not be compacted and should be kept soft to ensure its sound insulation. The gap between the door leaf and the door frame is embedded in the groove on the door frame by using an elastic material such as a sponge rubber strip, and is firmly clamped. The cross-sectional dimension of the sponge rubber strip should be 1mm larger than the width of the groove on the door frame, and protrude 2mm from the frame edge to ensure that the gap can be tightened tightly after the door leaf is closed.

The door lap joint of the double-sector steel soundproof door shall be made into double L-shaped seams. In the middle of the lap joint, a sponge rubber strip should be placed. When the door leaf is closed, the sponge rubber strip will be squeezed on both sides of the lap joint, and a gap of 2 mm wide should be left between the door leaves, and the wood between the joint and the wood should not be in direct contact. Outsourced steel soundproof doors should be wrapped in artificial leather. The rockwool blanket should be filled between the artificial leather and the wooden door leaf, and then pressed on the surface of the door leaf with a double-layer artificial leather bead, and then nailed with a foaming nail. The surface of the artificial leather should be tightly packed and stretched.

A gap of 5 mm wide should be left between the bottom of the steel soundproof door leaf and the ground, and then a 3 mm thick rubber strip should be nailed to the lower part of the door leaf with a long flat iron. The rubber strip at the contact with the ground should be extended by 5 mm to close the door leaf. A gap between the ground. The soundproof fireproof door with waterproof requirements, the door leaf can be made of refractory fiberboard, each side is set with a 5mm thick asbestos board, and then the 26th galvanized iron sheet is full, and the exposed door frame part should also be wrapped with galvanized iron sheet. The hardware of the steel soundproof door should be compatible with the function of the steel soundproof door. For example, the hinge should use a silent hinge.

A steel rubber soundproof door shall be provided with a sponge rubber strip in the middle of the lap joint. When the door leaf is closed, the sponge rubber strip is squeezed on both sides of the lap joint, and a gap of 2 mm width should be left between the door fans. The wood at the joint should not be in direct contact with the wood.

The steel soundproof door should be wrapped with artificial leather. The rockwool blanket should be filled between the artificial leather and the wooden door leaf, and then pressed on the surface of the door leaf with a double-layer artificial leather bead, and then nailed with a foaming nail. The surface of the artificial leather should be tightly packed and stretched. A gap of 5mm wide should be left between the bottom of the steel soundproof door leaf and the ground. Then the 3mm thick rubber strip should be nailed to the lower part of the door leaf with the long flat iron. The rubber strip should be extended by 5mm when it touches the ground, and the door leaf and the ground should be closed. Gap.
