Description

A wall insulation layer structure

technical field

The utility model relates to the technical field of buildings, in particular to the technical field of wall thermal insulation, in particular to a wall thermal insulation layer structure.

Background technique

As known in the industry, directly attaching decorative materials on the body of the building, such as marble or other similar materials, only plays a decorative role, but cannot play the role of heat insulation and fire prevention. The smaller the heat transfer coefficient of the building wall decoration material, the more energy-saving it will be. For example, in the hot summer, the smaller the degree of heat transfer from the outside to the room, the greater the temperature difference between the room and the outside. Therefore, when used indoors When the air conditioner is used, heat energy can be saved; on the contrary, in cold winter, because the indoor temperature is not easily transmitted to the outside world, it can ensure that the indoor temperature is significantly higher than the outdoor ambient temperature, so when the air conditioner or heating is used indoors, energy saving can also be reflected. The building insulation layer is conceived under the concept of energy saving. Existing thermal insulation layers are usually formed by directly bonding thermal insulation boards on the body of wall. Since there is no fireproof structure between adjacent two thermal insulation boards, the fireproof performance of this thermal insulation layer is relatively poor.

Detailed ways

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

In the description of the present utility model, it should be understood that the terms "first" and "second" are only used for descriptive purposes, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the number of indicated technical features . Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present utility model, "plurality" means two or more, unless otherwise specifically defined.

Referring to Fig. 1, a wall insulation layer structure with good fireproof performance, from the outer surface of the wall to the direction away from the outer surface of the wall, includes adhesives, insulation layers and panels connected in sequence; the wall includes the base wall and the setting In the plastering layer on the surface of the base wall, the wall insulation layer structure is usually arranged outside the plastering layer.

The insulation layer is composed of multiple insulation boards, and the multiple insulation boards are set in parallel. The parallel setting here means that the multiple insulation boards are arranged on the same plane in the form of rows and columns (forming the insulation layer), and any two insulation boards There is no overlapping or crossing between the boards; a fireproof insulation layer is provided in the joint between two adjacent insulation boards, and the fireproof insulation layer extends to the outer surface of the wall; the setting of the fireproof insulation layer has an Insulation boards are isolated, which can effectively prevent the spread of fire. In order to better play a fireproof role, a fireproof insulation layer can also be set on the four sides of each insulation board. The surface of the fireproof heat insulation layer is covered by a calcium-plastic board shell. and rising bolts are fixed on each side of the insulation board circumference. The fire barrier is preferably made of inorganic materials. The advantages of inorganic materials are excellent flame retardant properties, fiber reinforced cement boards, fiber reinforced calcium silicate boards, etc. have a high thermal coefficient ≤0.30, good impermeability, not easy to fall off, and excellent fire resistance. On the side of each insulation board close to the outer surface of the wall, the side of the insulation board close to the outer surface of the wall is bonded to the plastering layer on the outer surface of the wall by means of frame points. This connection method can not only The insulation board is firmly bonded to the plastering layer, and the amount of adhesive can be reduced as much as possible, so that the cost of the wall insulation layer structure is lower. The thermal insulation board adopts the prior art, and the bonding agent is a special bonding mortar. Bonding with adhesive in the frame point method refers to firstly selecting the bonding point on the side of the insulation board close to the outer surface, and then applying the adhesive to the selected transition point, the bonding area is not less than 40% . The panels are connected to the insulation board in one-to-one correspondence, so that the joints between the adjacent two panels correspond to the joints between the adjacent two insulation boards, and a sealing structure is provided between the adjacent two panels. Sealing; on the one hand, the sealing structure seals the seams between two adjacent panels, and on the other hand also seals the seams between two adjacent insulation boards.

The sealing structure is preferably made of silicone weather-resistant sealant. Silicone weather-resistant sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented with crosslinking agent, filler, plasticizer, coupling agent, and catalyst in a vacuum state. By reacting with water in the air it should cure to form elastic silicone rubber. The main function of silicone weather-resistant sealant is to seal the joint between two adjacent panels. As the panels will be affected by temperature changes and deformation of the main structure, the displacement will cause the joint width to change accordingly. Silicone weather-resistant sealant has a good ability to withstand joint displacement, and does not crack when it withstands changes in joint width for a long time.

The panel is preferably made of inorganic resin material, the inorganic resin material is preferably fiber reinforced cement board or fiber reinforced calcium silicate board. layer.
