Problems solved by technology

[0003] 1. The durability and reliability are poor, and the service life of the insulation material and the main body of the building is not synchronized
[0004] 2. The process is complex, the workload of plastering in wet work is large, and the degree of industrialization and standardization is low. The current polystyrene board or extruded board is a block material, which needs to be pasted on the surface of the outer wall piece by piece, which is labor-intensive and time-consuming. It is prone to defects such as misplacement, cracking of high-strength slurry insulation materials, cracking and falling off of facing brick veneer, and poor fire resistance
The thermal bridge will increase the overall heat transfer coefficient of the external wall, resulting in greater conduction heat loss, increasing the energy consumption of building heating and cooling; the difference between indoor and outdoor temperature and absolute humidity is large, and local condensation will occur on the inner wall or inside of the thermal bridge of the external wall Problem: due to the existence of temperature change stress, it is easy to cause cracks in the joints of the insulation board, the bottom of the parapet wall along the roof panel of the top floor building, and the cantilevered components outside the outer wall; the inner insulation of the outer wall is made of foamed polystyrene board or Extruded polystyrene board, due to low hardness and tensile strength, affects interior decoration and hanging and fixing objects; in addition, the installation process is complicated

Embodiment 1

[0038] ②. If Figure 6 , Figure 7 , Figure 8 , Figure 9 Shown: The connection method of the single-cavity gypsum insulation board used for internal insulation of the main body of the building. It is composed of a single-cavity gypsum insulation board and a brick-concrete wall. The number of single-cavity gypsum insulation boards 6 is increased or decreased according to the internal insulation requirements, such as Figure 8 When the internal insulation requirements cannot be met, use Figure 9 In the form of single-chamber gypsum insulation board 6 inner side keel 7 and brick wall 23, coat one layer of adhesive or adopt expansion tube to fix. Embodiment 1: A connection structure in which the exterior wall of a building is connected with a double-cavity gypsum insulation board 1 by using an overhanging concrete member

[0039] as an example

[0040] Such as image 3 , Figure 4 Shown: when the external concrete member is used, the main structural form of the shear wal...

Embodiment 2

[0042] Example 2: Taking the connection structure between the embedded steel parts in the building exterior wall and the double-cavity gypsum insulation board 1 as an example

[0043] Such as Figure 5 Shown: When pre-embedding steel components, pre-embed steel components 20 in the shear wall 12, fix B steel plates 21 on the double-cavity gypsum insulation board 1 corresponding to the pre-embedded steel components 20 and weld them, There is a B gap 22 between the insulation board 1 and the shear wall 12 to form an air cavity to increase heat preservation and sound insulation effects, and a layer of exterior wall paint 19 is also coated outside the double-chamber gypsum insulation board 1 .

[0044] Its advantage is identical with embodiment 1.

Embodiment 3

[0045] Example 3: Take the connection method of single-cavity gypsum insulation board for building thermal insulation as an example

[0046] Such as Figure 9 Shown: The single-cavity gypsum insulation board is used for the connection structure of the main body of the building for thermal insulation. It is composed of a single-cavity gypsum insulation board and a brick-concrete wall. The cavity gypsum insulation board 6 is connected to the keel 7 inside the single cavity gypsum insulation board 6 and the brick wall 23 through an adhesive (or an expansion tube connection).

[0047] Its advantage is identical with embodiment 1.

Abstract

The invention relates to a gypsum heated board and a method for connecting the gypsum heated board and a major building structure. The gypsum heated board is divided into a double-cavity gypsum heated board and a single-cavity gypsum heated board which take gypsum as a raw material, and the two-layer cavity structure has one hollow cavity and one solid cavity or two hollow cavities; and when the two-layer cavity structure has one hollow cavity and one solid cavity, an inner cavity is the hollow cavity, the inside of an outer cavity is filled with heat-insulating materials, and the inner cavity and the outer cavity are provided with ribs which are arranged in the staggered form. The gypsum heated board is used for external heat preservation of an external wall of a building and heat preservation of roofing. The connecting method is to connect the board and the major building structure by means of exterior projecting of a concrete member or a pre-buried steel member in a wall body. The single-cavity gypsum heated board is used for internal heat preservation of the external wall of the building; the inside of the single-cavity gypsum heated board is fixed with a keel; and the single-cavity gypsum heated board is connected with the major building structure through an adhesive or an expand tube. The gypsum heated board has the advantages of reutilization of industrial waste, energy-saving raw materials, environmental protection, sound insulation, water resistance, heat preservation, good fire resistance, convenient construction, quick assembly speed and wide application scope.

Description

technical field [0001] The invention relates to a thermal insulation material and its connection with a wall, in particular to a gypsum thermal insulation board and its connection method with a building main structure. Background technique [0002] As we all know, the current practice of domestic residential exterior wall insulation system is to paste polystyrene board or extruded polystyrene board on the exterior wall of the building. The external wall insulation system has the following shortcomings in practical application: [0003] 1. The durability and reliability are poor, and the service life of the insulation material and the main body of the building is not synchronized. [0004] 2. The process is complex, the workload of plastering in wet operation is large, and the degree of industrialization and standardization is low. The current polystyrene board or extruded board is a block material, which needs to be pasted on the surface of the outer wall piece by piece, whi...
