It can be seen that the stone curtain wall is essentially the enclosure structure of the building. The construction drawings for dry hanging stone mainly refer to the construction methods for stone installation. There is no design calculation book related to it. Dry hanging stone is a type of decoration that is integrated with the exterior wall. According to the requirements of the "Code for Quality Acceptance of Building Decoration and Renovation Engineering", it is necessary for a construction unit with corresponding decoration construction qualifications to carry out a detailed design of the building construction based on the original building drawings. The design drawings of dry hanging stone should be verified and confirmed by the original structural design unit or a qualified design unit through checking the relevant original data of the existing building, verifying and confirming the safety of the existing building structure. There is no need to approve the safety and physical properties of the dry hanging stone wall that is about to be constructed.
4. The amount of water added is 16% to 18% of the weight of the repair material, which is 8-9 kilograms of water per bag of material
Construction method:
1. Before use, it is necessary to clean the loose materials and dust on the surface of the repaired concrete, and only when there is no visible water can construction be carried out.
2. When mixing, the repair material should be mixed evenly according to the water consumption provided in the instructions (i.e. 8-9 kilograms of water per bag) before pouring for construction. If the pouring area and volume are too large, a small amount of fine stones or large sand can be added to reduce concentrated exothermic reactions. Pour the mixed slurry into the area that needs to be repaired, compact and smooth it, and cover it with plastic film and water it for curing in a timely manner after the repair slurry has finally set. In winter, it is necessary to cover it with cotton felt for insulation protection.
Modified phenolic fireproof insulation board is a composite board made by adding flame retardants, curing agents, smoke suppressants, and foaming agents to the board. The original phenolic board itself is an organic material that emits harmful gases such as thick smoke when burned. The modified product reduces these drawbacks, and the fire prevention effect can reach level A, with a thermal conductivity of. 29. The modified phenolic foam fire insulation board will not drop, melt, curl and other original phenomena during combustion, and will form a protective layer due to carbon formation during combustion, but a fatal and easily broken defect remains unchanged. The construction technology of phenolic insulation board is similar to that of polystyrene board. The general process is: leveling the foundation wall - marking the line - pasting phenolic board - mortar - grid cloth - grid cloth - decorative layer.
3. Road opening hours: Depending on the customer's design intensity and construction season, the fast opening hours are 2-8 hours.
Attention: This product is packaged in 50kg/bag (kraft paper composite bag)
Storage conditions: Dry environment for 12 months without affecting use
Study on the influence of various raw materials in EPS external insulation mortar on compressive strength, bond strength, and thermal conductivity of extruded polystyrene board to improve the insulation and crack resistance of EPS mortar. On this basis, the dosage of raw materials was adjusted, and the corresponding dosage of raw materials was determined to improve the insulation effect of EPS external insulation mortar; The influence of raw materials, composite additives, and sand cement ratio on compressive strength, softening coefficient, water absorption rate, porosity, drying shrinkage rate, cracking index, and crack resistance of crack resistant mortar was studied, and the raw materials were determined Research and analysis of lightweight composite insulation wall panels for children's photography. As a new type of building material for interior walls, there are many similar composite wall panels in current construction projects. However, our research on lightweight composite insulation wall panels overcomes the shortcomings of overweight and cracking in current wall panels, and has good energy-saving performance characteristics. Applying it to shear wall systems will be a wall material with good energy-saving properties.
