Description

A wall panel structure integrating light decoration, heat insulation and heat preservation

technical field

The invention belongs to the technical field of building wall panels, in particular to a wall panel structure integrating light decoration, heat insulation and heat preservation.

Background technique

Existing lightweight exterior wall systems have some of the following problems:

1. The structure of the plate is 30mm concrete outer layer + light steel keel + 10mm cement fiber board/calcium silicate board/9 cc board, and the light steel is exposed, there is no tongue and groove structure, and the hidden danger of water leakage is great;

2. The inner wall of the outer wall is a thin plate, and the material texture of the indoor partition wall (aerated block or strip) is not uniform, and there is no heavy feeling. The user's indoor experience is not good, and it is connected with the inner wall and indoors. It is inconvenient to connect and use materials during decoration;

3. The content of the adapter is relatively large, which increases the cost of the adapter;

4. On-site installation is difficult, the on-site welding volume is large, and the impact on the environment is large; and the adjustment allowance is relatively small;

5. The structural measures without interlayer expansion joints cannot absorb the horizontal displacement of the main structure during an earthquake, and the in-plane deformation performance of the plate is poor;

6. Under the same material cost, the thermal insulation performance is poor, and more thermal insulation material costs need to be added.

Therefore, in view of the above problems, it is of great significance to provide a wall panel structure integrating light decoration, heat insulation and heat preservation to solve the above problems.

SUMMARY OF THE INVENTION

The present invention provides a wall panel structure integrating light decoration, heat insulation and heat preservation, which effectively solves the above problems.

The light-weight decoration, thermal insulation and thermal insulation integrated wall panel structure of the present invention comprises a high-performance concrete surface layer, a light steel keel frame layer and an ALC board sequentially arranged from outside to inside;

The back of the light steel keel frame layer is hung on the main structure through wall panel adapters and bolt assemblies, and the upper and lower ends of the overall wall panel structure are grooved concrete flanging; the light steel keel frame The layer is arranged between the high-performance concrete surface layer and the ALC board, the light steel keel frame layer and the high-performance concrete surface layer are fixedly connected by stainless steel embedded parts, and the light steel keel frame layer and the ALC board are connected. They are fixed and connected by self-tapping screws; the two adjacent wall panel structures are snapped together by a tongue-and-groove concrete flanging, and a cavity gap is formed, and the cavity gap is filled with EPDM airtight glue The outer opening and inner opening of the cavity gap are filled and sealed with weather-resistant sealant through foam strips respectively; one end of the light steel keel frame layer of the wall panel structure is fixed and installed with a sleeve connector by bolts. The other end is fixed and installed with a U-shaped steel adapter by bolts; the adjacent wall panel structures are connected by a threaded steel sleeve installed between the U-shaped steel adapter and the sleeve connector; The connection parts of the wall panel structure are sealed by sealant;

The light steel keel frame layer of the wall panel structure is filled with fireproof insulation cotton.

The present invention has the following beneficial effects:

1. Concrete flanging with tongue and groove structure is used in the structure to ensure the waterproof performance of the plate. At the same time, the weather-resistant sealant on the outside prevents the entry of water on the outside. The internal test adopts EPDM air-tight dogma to compact the plate joints. A cavity is formed between them, which is equal to the indoor and outdoor air pressure, which ensures that the rainwater on the outside will not enter the gap of the board due to the difference in air pressure. The setting of the two materials and the tongue and groove structure greatly improves the waterproof performance of the outer wall;

2. The use of ALC board in the inner page not only ensures the overall fireproof and thermal insulation performance of the wallboard, but also saves the use of thermal insulation materials to a certain extent. It is basically a homogeneous material, which makes the connection processing of the two at the handover position more convenient, and it is also more convenient for later interior decoration. , which can realize the arrangement of electrical conduits, which is more cost-effective than cement fiberboard with a similar price;

3. Compared with the previous exterior wall system, this light exterior wall system has added a structural measure of interlayer expansion and contraction composed of U-shaped steel adapters, sleeve connectors and connected threaded steel sleeves, which can absorb the main structure. The horizontal displacement under the action of earthquake load, etc., avoids the plane deformation and damage caused by the failure of the wall panel to absorb the displacement under this action; the setting of the expansion joint can not only ensure the plane deformation performance of the plate under the action of earthquake, but also change the structural joint. It can also be used as a sliding hinged support for the plate, and the original transfer support is used as a fixed hinged support, which is more in line with the force model of a simply supported beam;

4. Through the setting of inter-layer telescopic nodes, the amount of adapters is greatly reduced, thereby reducing the cost of wall panels; at the same time, the difficulty of on-site installation is also greatly reduced by changing from the original vertical connection to the hanging connection. Improve the installation efficiency, shorten the installation period, and reduce the installation cost; at the same time, the workload such as on-site welding is reduced, water and electricity are saved, pollution is reduced, and the impact on the environment is greatly reduced.

5. The light exterior wall system adopts the all-dry construction method, and integrates decoration, heat insulation and heat preservation. It has a great contribution to the promotion of horizontal components and three-board areas to improve the assembly rate of buildings. Green building rating evaluation also has a positive contribution.

Of course, it is not necessary for any product embodying the present invention to achieve all of the above-described advantages simultaneously.
