At present, the types of exterior wall materials and high-rise buildings and steel skeleton filled walls commonly used in the construction industry include: 1. Plus 2C panels; 2. Hollow straw interior wall panels; 3. Gypsum interior wall decorative panels; 4. Cement hollow panels; 5. Brick-concrete structure filling wall; 6. Aerated concrete block. Although these wall materials have their own advantages, they also have the following disadvantages: the 2C board has poor strength, no waterproof, no heat insulation, short life, and basically no load-bearing; the hollow straw inner wall board has no sound insulation, low strength, and is easy to be affected by moisture. Deformation, easy to be heated and caught fire; gypsum interior wall decorative board, mainly for decoration and beautification, is easy to damage; cement hollow board, bulky, takes up a lot of space, poor sound insulation, heat protection and warmth preservation; brick-concrete structure filled wall, heavy weight, consumes energy Many, pollute the environment, waste resources and high cost; although aerated concrete blocks have certain advantages over the above materials, they still have the problems of large space occupation, difficult construction, high resource consumption and high production costs.

Invention content:

In order to solve the shortcomings of the above-mentioned exterior wall materials, high-rise buildings and steel skeleton filled walls, the purpose of this utility model is to provide a high-strength composite molding exterior wall panel with good comprehensive performance, wide application, and meeting the requirements of energy saving and environmental protection.

The technical scheme of the utility model is realized in the following manner:

A high-strength composite molding exterior wall panel, which is composed of a steel mesh layer, a cement layer, and a flame-retardant heat-insulating inner core, wherein the front and back surfaces of the exterior wall panel are both front and back cement layers, which are closely attached to the inner surface of the cement layer. There are two steel mesh layers in one body, and there is a flame-retardant and heat-insulating inner core between the two steel mesh layers. There are also multi-point connection supports between the two steel mesh layers. The two steel mesh layers and the supports form a cage that will The heat insulation inner core is wrapped; the front and back cement layers are molded by the wall panel machine on the two steel mesh layers to form the front and back sides of the outer wall panel.

The flame-retardant and heat-insulating inner core may be a rock wool board or a polystyrene board.

Both sides of the exterior wall panels are provided with connecting convex grooves or connecting grooves for splicing.

The thickness of the cement layer 5 is 25-30mm.

The thickness of the formed exterior wallboard is 110mm.

The positive effect of the utility model is:

1. Fire protection: Because the steel wire grid is filled with flame-retardant, heat-insulating and heat-insulating materials, 25-30mm thick cement mortar is compounded in the mold on both sides, and a solid and complete firewall board will be formed after solidification.

2. Anti-shock: It uses a steel wire mesh cage as the skeleton. After assembly, the steel wire mesh is connected into one. performance.

3. Sound insulation: When both sides are coated with 30mm thick cement mortar, the sound insulation is 48db; when both sides are coated with 25mm cement mortar, the sound insulation is 48db, which can meet the requirements of the secondary standard for partition walls.

4. Freeze resistance and moisture resistance: the inner core material is rock wool board or polystyrene board, the water absorption rate of rock wool board is 0.1%-0.32%, polystyrene board hardly absorbs water, and its moisture resistance is better than that of red brick wall. Its frost resistance reaches the D25 level frost resistance label.

5. Small size: After plastering mortar on both sides of this high-strength composite exterior wall panel, the thickness does not exceed 110mm. Compared with the brick wall, the same building area can increase the utilization factor of the usable area by more than 13%.

6. Low construction energy consumption and good building energy conservation: the high-strength composite molded exterior wall panel has low energy consumption in manufacturing and the lowest energy consumption in use. The manufacturing energy consumption of high-strength composite molding exterior wall panels with a 110mm thick rock wool inner core is 14.30kg standard coal/m ² , while the manufacturing energy consumption of a 240mm thick brick wall is 25.61kg standard coal/m ² ; the 490mm thick brick wall Manufacturing energy consumption is 53.50kg standard coal/m ² . Compared with brick walls, every 1m ^{2 of} high-strength composite molded exterior wall panels can save 5kg of standard coal for heating.

7. Convenient transportation and construction, no loss, and short construction period: The high-strength composite molding exterior wall panel is light in body, convenient in transportation, assembled construction, fast in speed, without loss, and the plate can be disassembled and reused for many times. The construction speed is faster than that of red bricks. Ten times that of 24 walls, 4 times lighter than red bricks, and the service life is much longer than red brick walls; the strength of a single board exceeds the third-grade hollow cement floor, and each board has concave and convex grooves, which is very convenient for assembly, up, down, long and short Arbitrary connection, it is the first choice for the internal and external filling walls of modern high-rise buildings, large steel roof truss factories, and internal and external walls.

8. It is convenient for cutting and splicing and adding various finishes: during construction and installation, any size can be cut and spliced according to the needs, and various interfaces and special shapes can be made. Various finishes can be made on the surface of cement mortar, such as mosaics , architectural coatings, facing bricks, wallpaper and tiles, etc., can also hang various wall cabinets.

9. Low overall cost: Using this high-strength composite molded exterior wall panel as wall and roof materials can save 5%-15% of the cost.
