Description

Prefabricated load-bearing thermal insulation decorative composite wall panel

technical field

The utility model relates to a load-bearing and enclosure wallboard with thermal insulation performance, in particular to a prefabricated load-bearing thermal insulation decorative composite wallboard.

Background technique

During the implementation process of banning the use of clay bricks in my country's construction industry, a large number of non-clay products have emerged, but generally speaking, these non-clay products lack breakthroughs, and they have not been able to get rid of the traditional clay bricks. Poor performance and low construction efficiency. In order to meet the required building energy-saving standards, thermal insulation must be done on the outside of the wall, and with the gradual improvement of energy-saving standards, the practice of continuously increasing the thickness of the external insulation layer will become more and more unfeasible. Because this approach not only reduces the usable area, but also increases the construction cost, sometimes it is even difficult to implement. In addition, the existing insulation boards made of organic materials are mainly extruded, molded polystyrene or foamed polyurethane. These organic materials are all derived from petroleum, not only costly, not flame retardant, but also cause great pollution to the environment when burned and discarded. The insulation board made of inorganic materials is mainly based on rubber powder particle insulation slurry, XR inorganic insulation slurry, etc. Although this type of inorganic material insulation board has higher strength than organic material insulation board, it has a large thermal conductivity and poor thermal insulation performance; and because of its strong water absorption, the requirements for waterproof surface layer are relatively high, which makes the construction cost It has been greatly improved; moreover, when the waterproof surface layer is thicker, it is necessary to carry out multiple plastering procedures to complete the operation, and the wet operation volume is large, and it is also greatly affected by the weather.

Utility model content

The purpose of this utility model is to provide a prefabricated load-bearing thermal insulation decorative composite wallboard which can overcome the deficiencies in the prior art and has the functions of fire prevention, waterproof, environmental protection, heat preservation and decoration.

The utility model is realized as follows: a prefabricated load-bearing thermal insulation decorative composite wallboard, the composite wallboard is wrapped with a thin-walled shell outside the thermal insulation core board with a waterproof protective film, and a reinforcing body is arranged in the thin-walled shell.

The reinforcing body in the thin-walled shell can be reinforced materials such as steel bars, bamboo bars, glass fibers or chopped organic short fibers that can support and strengthen the shell panels of the thin-walled shell, so that Effectively improve the strength of the thin-walled shell, ensure the mechanical performance of the composite wall panel, and meet the needs of use in buildings.

The thermal insulation core board with a waterproof protective film is made by putting thermal insulation material into a bag made of a waterproof protective film and then vacuum-sealed, that is, with thermal insulation properties such as scattered expanded perlite or expanded vermiculite. The good material is filled in the bag made of plastic film, and after the film is prepacked and evacuated to shape, it becomes the insulation core board with waterproof protective film.

The thin-walled shell of the utility model has no obvious reduction in strength under long-term wet and water environments; in addition, the waterproof protective film on the heat preservation core board has excellent waterproof and airtightness, which can meet the temperature tolerance under the use environment; Even when the moisture content of the wallboard is high, the insulation performance of the insulation core board can remain unchanged. Therefore, the utility model has stronger waterproof performance. The thermal insulation material in the thermal insulation core board of the utility model can not only withstand higher temperatures, but also as long as the thin-walled shell does not undergo major changes, even if the internal waterproof protective film fails, the waterproof coating layer can be added outside the wall. It can also restore the original enclosure and thermal insulation performance of the composite wallboard.

The utility model effectively and rationally combines the load-bearing, enclosure, heat preservation, decoration and other performances of the wall, and overcomes the poor fireproof and waterproof performance, non-environmental protection, high cost and large area occupied by the existing external wall heat preservation method. Many disadvantages. The use of the utility model can reduce the thickness of the wall body, increase the use area, and reduce the cost of building materials and construction costs of the wall body. The utility model is suitable not only as a load-bearing wall body of a new low-rise building, but also as an enclosure wall body of a multi-storey or high-rise building.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Directly used as the pouring inner film of the thin-walled shell, the whole body is poured together to form the composite wallboard

As shown in Fig. 1 and Fig. 2, the exterior of the utility model is a lath-shaped thin-walled shell 1, which can be made of cement, concrete, high-strength gypsum, magnesite cement and other materials that can be poured and maintained. The wall thickness of the thin-walled shell 1 can generally be controlled at 20-40mm. A reinforcing body 2 is lined in the wall plate of the thin-walled shell 1, and the reinforcing body can be selected from steel bars, bamboo bars, glass fibers or chopped organic short fibers.

The insulation core board 3 in the middle of the thin-walled shell 1 is to put a plastic film bag into a shaped container and fill it with insulation materials such as expanded perlite and/or expanded vermiculite in bulk, and of course other materials with good insulation performance can also be used; Then vibrate, vacuumize, seal and shape, and make it into the desired shape. The thermal insulation core board 3 can be directly used as the pouring inner membrane tool of the thin-walled shell 1 after prepacking and vacuumizing the shape of the film, and integrally poured together with the thin-walled shell 1 to form a composite wallboard. If the processing enterprise has a high degree of industrialization, it is also possible to efficiently prefabricate the thin-walled shell 1 with ports first, then put the waterproof film bag into the cavity of the thin-walled shell 1, and then fill it with insulation and materials, and vibrate Solid, vacuumize, seal, and finally close the port of the thin-walled shell 1, that is, the cost composite wallboard.

The vacuum-pumping and shaping of the insulation core board 3 does not require a complete vacuum state, but a quasi-vacuum state is sufficient. In addition, the plastic film bag of the waterproof protective film used for the thermal insulation core board 3 should have good performances such as waterproof, sealing, resistance to corresponding temperature and aging resistance, so as to ensure the thermal insulation performance of the thermal insulation core board 3 during use.

In addition, the thermal insulation core board 3 in the thin-walled shell 1 can be a whole, or a composite structure assembled from multiple units.

The external dimensions of the composite wallboard are preferably selected as follows: the board length is 2400-4500mm, the width is 600-1200mm, and the thickness is 200-300mm; the wall thickness of the thin-walled shell 1 is 20-40mm. The length of the composite wall panel is selected to correspond to the floor height of the building, and the selection of other dimensions is determined comprehensively with reference to the length of the wall panel and the longitudinal and lateral forces on the panel.

In addition, the plate side ribs and plate ends of the thin-walled shell 1 are not designed in a simple plane, and several grooves or ribs may be provided, so as to minimize the influence of thermal bridges. Between the grooves, connecting ribs can be arranged to strengthen the connection.
