Description

Integral cement composite thermal insulation exterior wall

1. Technical field

The utility model relates to an integral cement composite thermal insulation outer wall.

2. Background technology

At present, there are generally two forms of energy-saving buildings: one is to make an insulation layer outside the wall. This method has the following disadvantages: 1. The outer insulation layer needs to be re-constructed, which is labor-intensive, time-consuming, and material-intensive. 2. Large thermal bridge area. 3. The construction period is long. 4 The self-weight of the building is large, and the anti-seismic performance is poor. The second is to use glass fiber reinforced cement (GRC) external wall insulation board (JC | T893-2001), this method still has great shortcomings: 1. The cost is high, and quick-drying cement must be used in production, while ordinary cement cannot Production, and quick-drying cement is twice as much as ordinary cement. 2. The thermal bridge area of the composite board is large. The thickness of the ribs on both sides of the composite board is about 1 cm, and the adhesive seam is calculated with 5 mm. The thermal bridge area of each board is 0.075 square meters. 3. The impact resistance and bending force of the composite board are poor, and the surface layer and the insulation layer basically have no adhesion, so they cannot form a whole, and can only rely on the palm force of the ribs on both sides. 4. It is difficult to remove cracks when this type of board is installed. 5. The installation and construction are complex, including seams, glues, wedges, clips, windows, doors and other processes.

3. Contents of the invention

In order to overcome the defects of the above energy-saving buildings in construction, material production and supporting equipment, the utility model proposes a bridge-free, non-cracking, low-cost, high-quality and one-time construction of water, electricity, gas pipes, doors and windows. The overall cement composite thermal insulation exterior wall.

The utility model is realized in the following way: pre-treat the heat-insulating laminates, open grooves around the required heat-insulating laminates, and open grid-like grooves on the upper and lower sides, the bottom of the grooves is larger than the upper part to form a trapezoid, and water and electricity are opened on the inner surface of the wall. 1. The air pipe groove, open the door and window, and the surrounding area should be larger than the actual opening size, and then spray the adhesive mortar. The excavated insulation board is made into the actual size of the door and window, and the thickness of the cement plastering layer is thickened on it, and then placed flat in the middle of the opening, and the steel wire mesh is vertically placed in the surrounding seams, and the water, electricity, and gas pipes are placed in the groove Put the insulation board cover on the inside and the outlet. Lay reinforced steel wire on the insulation layer, expose the connector, and connect with the vertical steel wire mesh in the opening, plaster the surface and spread glass fiber mesh cloth, and lay isolation film on it, which can be multi-layered and pressed for continuous production operation, without isolation film After the cement is less solidified, it can also be laminated and produced in multiple layers; after the upper cement layer is solidified, it can be reversed to make the other side. Both sides of the inner wall can be made at one time.

The installation and construction of the integral cement composite thermal insulation exterior wall is carried out at the same time as the frame. After the vertical frame steel bars are bundled, the integral wall is hung up and placed between the two frame steel bars. , the reserved steel wires on the wall are respectively connected with the steel bars on the frame, the end face of the wall can be used as the left and right side formwork of the vertical frame and the bottom formwork of the upper frame, and the outer formwork of the frame can be used as a single-sided cement composite insulation strip, the frame After the inner formwork is installed, cement, sand and gravel are poured, and the frame and the integral wall are firmly combined into a whole.

The integral cement composite thermal insulation exterior wall has the following characteristics:

1. The heat insulation effect is good. Because the whole wall has no side ribs, bridge heat is eliminated, so this process is superior to all external insulation, internal insulation and slat insulation boards. It is not only suitable for buildings and living rooms, but also suitable for large-scale cold storage construction.

2. Light weight. The overall cement composite thermal insulation exterior wall weighs about 38 kilograms per square meter, which is only 760 kilograms for a 20-square-meter wall. The general brick wall weighs about 8 tons, which can reduce the total cost of the building by one-half. The weight creates conditions for earthquake resistance.

3. Anti-earthquake and anti-seismic, the surface layer of the overall cement composite thermal insulation exterior wall is composed of cement, bonding mortar and thermal insulation layer. No detachment, increased flexural load and enhanced impact resistance. During installation, the reinforcing ribs of the wall are connected with the frame ribs, and the grooves on the end face are added. After the frame is poured with cement, the two are connected as a whole. Even if the building falls, the wall will not collapse and hurt people.

4. The construction method of simultaneous construction of the integral cement composite thermal insulation exterior wall and the frame breaks the traditional construction mode of laying the frame first and then building walls or installing slats. It saves many construction procedures: (1), saves water , laying of electricity and gas pipelines and lines. (2), save the construction of doors and windows. (3), save the construction of external insulation. (4), save the wall construction. (5) The installation and disassembly of most templates is omitted.

5. After construction, the wall can be put on or not, and the paint and finish can be painted directly, or the finish layer can be made at one time when making the wall. The finish layer is paint, wall paint, tile, stone , plastic aluminum plate, etc.

In short, the integral cement composite thermal insulation exterior wall can make the building thermally insulated, energy-saving and environmentally friendly. Effect. This technology is not only suitable for the construction of buildings and living rooms, but also for the construction of cold storage. It is not only suitable for the production and installation of exterior walls, but also for the production and installation of interior walls. Its promotion will definitely produce immeasurable economic and social benefits. .
