EPS cement sandwich panels are a popular choice in modern construction. The two outer cement - based facings are formulated to resist weathering and mechanical stress. The EPS foam in - between is a lightweight, closed - cell material. This combination results in a panel that is both light and strong. During production, the cement slurry is carefully applied to both sides of the pre - formed EPS board, followed by curing to enhance the bond. The surface of these panels can be smooth or textured. With a natural gray - white color from the cement, they can also be pigmented. They meet various national and industry standards regarding strength, insulation, and fire resistance.
Boards: smooth, non-asbestos, calcium silicate boards , 5mm thickness each side
Core: lightweight core of portland cement and expanded polystyrene bead aggregates
Finishing: no need for plastering
Between panels: tongue and groove system using adhesive material
No Smoke emission, No Toxic gas distillation and No Water penetration
Strength: No cracking, No breakage
High efficiency and short construction period
The composite wall panel is easy to install and does not need bricklaying, so it can shorten the construction period, that is, ready to use. The slotting is quick, the water and electricity pipeline is easy to install, and the construction efficiency is several times that of the general masonry. Install a wall panel (1.49) = masonry 120 standard bricks + 7.2M2 (double-sided secondary) plastering, every ordinary worker can install 30M2 wallboard on average every day, ie = technical workers masonry 1500 bricks +86M2 plastering.
Earthquake resistance, Anti-seismic
Since the composite wall panel is a fabricated wall, the panel itself is a three-in-one structure. The board is connected as a whole, and the impact resistance and bending resistance are all incomparable to the masonry wall. Generally, the masonry will hit a big hole when it is impacted; it will endanger life and property when the earthquake collapses.
Sound insulation
The sound insulation effect of the lightweight wall board reaches 42dB, which is in line with the national national sound insulation test standard GBJ121-88. Due to the high density and easy reflection of the material, it has a strong sound insulation effect, which is superior to the general masonry; the general sound insulation effect of the masonry is 35-37dB.
Moisture and Water resistance
Due to the special properties of fiber cement boards, the moisture-proof and water-resistant functions are particularly prominent. Experiments have shown that the wall panels can be cemented into the pool without any waterproof finish, and the back of the wall can be kept dry without leaving any marks. In the wet weather, the walls will not show condensation water. . Ordinary masonry is not moisture-proof, and it will be peeled off in a long time.
Environmentally friendly
There is no pollution in the production process of light wall panels. All materials of wallboards do not contain harmful substances and radioactive substances. They are in line with the National Standard for Radiation Hygiene Protection of Building Materials (GB6566-86) and are green products. The use of fly ash and coal gangue to recycle waste is extensively used, and the insulation function of the calcium silicate board could saves energy.
Low price
From the aspects of increasing the practical area, reducing the transportation volume, reducing the labor intensity, reducing the structural cost, and constructing civilization, the cost is very low. In terms of the practical area of 1 square meter per wall for each extension of 12 square meters, the wall panel has increased the use area. If we consider the use of lightweight wall panels from the design, it can reduce the standard of structural materials, and the overall cost of the building can be greatly reduced.
1.Put wire,transport board in place, pop up or down the wall plate and gauge double in the respective axis mount.
2.Any use of drilling to cut according to wall plate specifications.
3.Put cement binder and wall board in foundation.
4.Put cement binder,two pieces of the tenon on one side cement to wipe polymer mortar on any tongue and sides.
5.Installation,firstly prepare for the installation of plate moved into connection location,wall correction with a crowbar,use force tightly,to let polymer mortar extrusion from the joints in high spirits.
6.Adjustment,use wood wedge to bit into the bottom of the wall plate so that it adjust vertical formation
7.Correction,fix,use more than 2m or 2m guiding rule to check vertical,flat correction.
8.Grout,fill the pulp,use polymer mortar to infill and flatness after correcting the wall body,use polymer mortar to fill the gap size up or down.
9.Fixed,upper part of wall panels with Φ6mm or Φ8mm steel reinforce in the middle of walls by 45 degrees to bit into,the bottom with "7shaped"ribbed steel,one head is bitten into concrete base,the other head is bitten into the wall plate.
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.
