Insulated Precast Concrete Sandwich Wall Panel for Office/Bathroom/Factory
Information of Sandwich Wall Panel
The sandwich wall panel uses ordinary portland cement, sand and fly ash or other industrial waste such as water slag, slag, etc. as fine aggregate, and then adds polystyrene particles and a small amount of inorganic chemical additives to cooperate with full automatic high efficiency A special mixing system for forced light aggregates, which introduces air during the mixing process to form a honeycomb-like stable pore in the core layer to further reduce the product bulk density, which not only reduces the material cost, but also achieves the ideal thermal insulation and sound insulation effects. Polystyrene particles and pores are evenly distributed inside the product, so that the concrete forms a circular honeycomb skeleton, which supports each other and increases the pressure resistance. The addition of fly ash not only improves the workability of the concrete slurry, but most importantly, it enhances the strength of the cement in the late stage, thereby enhancing the strength after the product is cured, the flexural strength is increased by 80%, and the modulus of rupture is increased by more than 50%.
Features of Sandwich Wall Panel
1. Light weight: The wall weight is about one third of the brick wall, which reduces the building load and reduces the construction cost.
2. Thin body: The thickness of the wall is about one half of that of the brick wall. The wall occupies less area and has a large practical area.
3. Solid core: the wall is non-foaming, no hollow drum, can be slotted, digging, single-point hanging force exceeds 50 kg.
4. Fast: The wall adopts the assembled dry construction method without plastering, and the construction efficiency is 5 times higher than that of the masonry method.
5. Fire resistance: The wall has good fire resistance and heat insulation performance. The wall temperature is only 60 ºC when it is burned at 1000 ºC for 1 hour.
6. Waterproof: The wallboard is directly cemented into a pool without waterproofing. After being filled with water, it is left for 48 hours without leakage.
7, Sound insulation: SGS authoritative testing, wall (100mm) sound insulation can reach 42dB.
8. Energy saving: The wall insulation effect is 3 times that of the brick wall, and the energy saving of air conditioning and heating equipment is 60%.
Usage of Sandwich Wall Panel
1. Lightweight EPS sandwich panel as non-load-bearing internal partition wall can be used in hotels, hotels, schools, hospitals, office buildings, high-end apartments, stadiums, exhibition centers and other buildings to meet different customers' needs for modern and indoor indoor and outdoor environments. Claim. This product is simple and convenient for splicing and installation, more than 6 times faster than the block wall, which can greatly shorten the construction period, and the construction is particularly fast.
2. Hotel, ktv, meeting room, pay more attention to privacy and sound insulation. The lightweight EPS sandwich panel is a solid wall board, which meets the Chinese people's need for a solid wall. The closed microporous structure inside the plate effectively blocks the dual functions of sound transmission and sound absorption to ensure privacy. The air insulation is ≥48dB, and its sound insulation effect is better than that of ordinary aerated bricks.
3. For leisure and entertainment restaurants, due to the high strength of lightweight partition boards, it can hang heavy objects such as wall cabinets, air conditioners, and televisions: decorative plates can be directly nailed to the wall boards with iron nails. It can be sawed, nailed, drilled, cut, and the building pattern can be made at will. The surface of the lightweight partition board has good flatness, no plastering is required, and wallpaper, wall tiles, and spray coating can be directly applied after filling.
4. Workshops and factories (including steel structures). Lightweight partition boards are mainly considered as fire prevention and fire protection requirements as workshop and factory partition walls. Lightweight partition boards have undergone high-temperature combustion tests at 1000 ºC. The test requires that no harmful gas is generated during the combustion process, and it belongs to Class A fireproof materials.
Installation Process of Sandwich Wall Panel
1. Grass-roots cleaning
Clean up the grassroots that needs to be constructed, and the mortar or concrete protruding from the wall must be cleaned with tools to facilitate the construction of the next sandwich wall panel.
2. Elastic line bin
Perform the elastic line operation on the ground and the appropriate position of the wall surface to ensure that the installed sandwich wall panel can be horizontal and vertical. Position and grade the edges of the partition wall and the edges of the doors and windows, and then select the plates with the same specifications according to the dividing lines.
3.Sizing preparation
Cut the sandwich wall panel as needed, pay attention to adjust the width and length of the sandwich wall panel to minimize unnecessary losses. Then mix cement and medium sand in a ratio of 1: 2, and then add building glue to prepare a paste. When sizing, first use the water to paint the uneven grooves of the partition board, and then apply the polymer mortar to the uneven grooves of the partition board and the baseline of the floor.
4.Install wall panels
Move the sandwich wall panel to the position where it needs to be installed, stand it up, and align it up and down with the baseline. Use a shovel to pry the partition board from the bottom of it, and then press the board firmly against the board. , Make the mortar overflow from the joint, and then temporarily fix it with a wooden wedge, check the flatness and verticality of the partition wall board. After the inspection is completed, the connecting part between the wall panel and the wall panel needs to be fixed with a special steel bar at an angle of 45 downwards.
5. Grouting construction
After the sandwich wall panel is installed and calibrated, it is filled with cement mortar with a mix ratio of 1: 2 and the building glue is blended. The upper and lower gaps of the wall board and the joints between the boards must be used as much as possible mortar to fill. In the process of grouting, if you want to bury a concealed pipeline or a switch box in the wall, you can use mortar to fill it after the installation is complete.
6.Finishing
If you want to install a door frame on a lightweight partition wall, you can use a splint to cover the door directly on the wall panel, fix it with iron nails, and then use a decorative panel for the cover. Finally, the surface of the partition wall is coated with paint. You can also choose to paste your favorite porcelain to achieve certain aesthetic requirements.
