EPS cement sandwich panel, made from surface panel calcium silicate board, core material with cement, eps, sand, fly ash.
After complicated chemical reaction under high temperature, high pressure and steam curing. Has the characteristic of lightweight, excellent fire insulation, water proof, sound proof performance.
Since eps cement sandwich panel is a highly thermally insulating cement-based material, it can be used for both internal and external construction. Besides, eps cement sandwich panel have good insulation capability.
One of its advantage in construction is its quick and easy installation. Because the material can be routed, sanded, or cut to size on site using standard carbon steel power tools.
Superiority of Sandwich Cement Board
1,High strength and not deformed
Because of the high strength and good overall performance of the lightweight sandwich cement board, it can be used as the wall spacing with high height. As long as the steel structure is simply anchored, the steel is buried in the wall, and the wall is large span and high. The body does not need to increase the cylinder of the wall, and its impact resistance is 1.5 times that of the general masonry. Walls with a height of more than 3 meters should be as thick as 220 mm if they are made of general masonry. When the height exceeds 5 meters, the column is added, and the labor cost and the place are occupied.
2, Increase the practical area
Generally, the indoor partition wall can be made of composite partition wall board with a thickness of 75mm. It is 85mm thinner than the traditional 120mm wall and plastering. For each 12m extension wall, the utility area can be increased by 1 square meter, and the overall room area increase rate is 4-6%, the added value of the real estate of the property is higher than the sandwich cement board cost. Generally, the masonry is at least 160 mm thick, occupying a valuable practical area. If you use the wall panel to make the inner partition, you can add a few square meters of the practical area by purchasing the same size of the house at the same price.
3, Lightweight, Arbitrary interval
Since the weight per unit area is 1/6 of that of a general 120mm thick masonry, the weight of the structural wall can be reduced, the bearing capacity of the beam and column can be reduced, and the indoor space can be arbitrarily spaced. A house is 180-200 tons (3 meters high) per 1000M2. An office building is reduced by 250-200 tons (3 meters high) per 1000M2. If the height of the house is more than 3.5 meters, the thickness of the masonry wall must be increased to 200mm. At this time, 600 tons can be reduced every 1000m2; the general masonry should be built above the beam, which can not be randomly spaced, which has great limitations.
4. Class A fireproof material
The composite wall board is burnt at 1000 °C for 120 minutes without damage. It has been tested by the National Fireproof Building Materials Quality Supervision and Inspection Center, and the fire performance has reached the national A-level standard to ensure absolute fire prevention. Generally, the masonry has no heat insulation function and conducts when exposed to heat, and not conducive to fire prevention.
5, Can be nailed, can be pasted
The lightweight wall panel can be bonded to the building lime sand, cement slurry, etc., and the wall decoration paste bricks need no special treatment. It can be nailed, drilled and anchored in any part. The single point hanging force is above 50 kg. Generally, masonry, especially solid masonry, can not be arbitrarily nailed, which brings trouble and difficulty to the later decoration work.
6, Construction is simple and civilized production
The installation process of the lightweight sandwich cement board is simple, the ordinary workers will be installed in a short time, the construction tools are simple, and there are no special requirements. The wall panel can be cut to adjust the width and length. During construction, the transportation is simple, stacking is hygienic, no need to be swayed, dry work, no mud, low loss, little waste on the construction site, and civilized construction. The weight of material transportation is 1/6 of the weight of the original masonry; general masonry construction waste is more, the construction site is dirty, chaotic, and poor, and the horizontal transportation and vertical transportation pressure are great.
7, 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 sandwich cement board on average every day, ie = technical workers masonry 1500 bricks +86M2 plastering.
8, 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.
9, 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.
10, 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.
11, Environmentally friendly
There is no pollution in the production process of light wall panels. All materials of sandwich cement board 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.
12, 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 sandwich cement board 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.
Installation manual of Sandwich Cement Board
1 Release and lift the board: The baseline of the projectile in the wallboard installation is perpendicular to the bottom of the board or the bottom of the beam to ensure that the wall panel is straight. A 1.49 square wall panel can be transported freely.
2 Saw board: According to the requirements, the machine can be arbitrarily cut and the width and length of the wall board can be adjusted to reduce the wall panel loss rate.
3 sizing: Use cement and medium sand (1:2) and add construction glue to make a paste. First use the water to brush the concave and convex grooves of the wet wallboard, then apply the polymer mortar to the concave and convex grooves of the wallboard and the floor baseline. .
4 Loading the board: Move the wall board with the good mortar to the loading position, raise the baseline position up and down, and use the iron shovel to lift the wall board from the bottom to make the board and the board tight.
5 In place: Firmly press the wallboard to squeeze the mortar out of the joint to ensure that the mortar is full and temporarily fix it with a wooden wedge.
6 Correction: Check the straightness of the flatness and verticality of 2 meters: the iron shovel adjustment, and then use the wooden wedge and the steel bar to fix it up and down.
7 Stapling: The connection between the wallboard and the wallboard must be anchored with Φ6×200mm steel bars inclined at 45°.
8 Fixing: After correcting with both sides of the 30×30mm wooden wedge, drill the hole at the 45° angle with the impact drill at the 45° angle, and then anchor with Φ6×200mm steel.
9 Grouting: Install the calibrated wallboard with cement mortar (1:2) and add the construction glue to adjust the seam between the upper and lower seams and the board to the polymer paste, and pull out the wooden wedge. The mortar is filled.
10 Slotted embedding pipe: If you want to embed dark pipeline, switch box, etc., you can install it with impact drill or portable electric saw cutting slot, and then fill it with mortar polymer after installation.
11 Door frame: The door frame can be covered with a splint directly on the wall panel, anchored with iron nails and the wall, and decorated with a cover.
12 Plastering Paint: Finally, apply the top coat. If the tile is attached, there is no need to scrape the ash, and the tile can be directly attached to the wallboard with the cement slurry, or the wallpaper, the wood slab, etc. can be directly pasted.
