Description

Technical Field

[0001] This utility model relates to the field of wall insulation building, specifically to a self-locking aerosol felt composite board. Background Technology

[0002] The wall insulation building structure includes a connecting layer close to the base wall and a finishing layer away from the base wall. The connecting layer is used for fixed connection with the base wall, and an insulation layer is connected between the connecting layer and the finishing layer. The insulation layer material can be aerogel felt, cement-based aerogel insulation board, inorganic foamed aerogel insulation board, etc. Among them, aerogel felt is a flexible insulation material composed of aerogel and fiber-reinforced materials. It has extremely low thermal conductivity, is lightweight, highly hydrophobic, and has good mechanical properties. By combining nano-scale aerogel with fiber materials, it solves the problems of fragility and low strength of traditional aerogel, making it widely applicable in the construction field.

[0003] However, during the installation of existing wall insulation buildings, the instability of the connectors between the connecting layer and the finishing layer often leads to uneven thickness between the connecting layer and the finishing layer, ultimately resulting in an uneven finishing layer. In addition, the flatness of the finishing layer is often adjusted by manual measurement, but manual measurement is subject to many influencing factors that can lead to uneven installation of the finishing layer, and it is also time-consuming and labor-intensive, which will result in low installation efficiency. Based on this, the following improvements are proposed. Utility Model Content

[0004] The present invention aims to provide a self-locking aerocondensing felt composite board to solve the problem that aerocondensing felt is prone to dust shedding during use, which not only adversely affects the stability of the material's thermal insulation performance but also pollutes indoor air.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking aerosol felt composite board, comprising aerosol felt, first plates disposed on both sides of the aerosol felt and a wrapping layer, and a connector, wherein the connector comprises a screw and a threaded cylinder, the screw passing through the first plate in sequence and being threadedly connected to the threaded cylinder.

[0006] The beneficial effects of this solution are as follows: by wrapping the aerosol felt with the wrapping layer, the aerosol felt and connectors can be bound together as a whole, preventing the aerosol felt from shedding powder or cracking due to looseness. At the same time, the wrapping layer has a certain degree of toughness and can expand and contract with the slight deformation of the aerosol felt, which does not restrict the normal state of the aerosol felt and can improve the tear resistance of the overall structure. The composite board can significantly shorten the assembly time and is suitable for large-scale production or rapid on-site construction.

[0007] Preferably, as an improvement, the wrapping layer is set as a mixture of an air-barrier membrane or a reinforcing mesh and mortar, the threaded cylinder is located on the inner or outer side of the wrapping layer, the cross-section of the wrapping layer is U-shaped and wraps the edge of the aerosol felt.

[0008] Preferably, as an improvement, the wrapping layer is set as a second plate, the second plate has a positioning hole for the threaded cylinder to pass through, and the edge of the aerosol felt is wrapped with a mixture of air-tight membrane or reinforcing mesh and mortar.

[0009] Preferably, as an improvement, the first plate has a fixing hole for the screw to pass through.

[0010] Preferably, as an improvement, the first plate is radially slidably provided with a stop block at the fixing hole. The stop block is provided with an inclined surface. The stop block is used to push the inclined surface against the head of the screw, and the stop block is used to support the screw through the inclined surface.

[0011] The beneficial effect is that the screw head is embedded in the fixing hole, and long-term suspension causes the fixing hole to deform, resulting in poor structural stability. Therefore, the use of abutment can effectively reduce the damage to the fixing hole, thus ensuring the stability of the first plate suspension structure.

[0012] Preferably, as an improvement, the abutment is slidably connected to the upper and lower sides of the fixing hole, and a spring is provided between the abutment and the first plate. The spring is used to push the inclined surface of the abutment against the screw head, and the inclined surface has a groove for the screw head to be inserted.

[0013] The beneficial effects are as follows: When the screw is screwed into the threaded cylinder, it will penetrate the cylinder. At this time, the screw head will press against the inclined surfaces of the upper and lower abutments. The abutments will drive the inclined surfaces to slide vertically, widening the distance between the upper and lower abutments. Finally, the edge of the screw head will be engaged in the groove, and the groove and the screw head will be locked. A spring is also provided between the abutment and the finishing layer. Therefore, the spring can dampen the vibration of the finishing layer and prevent the vibration from being transmitted to the connecting layer and affecting the stability of the structure. In addition, the engagement between the screw head and the groove provides support for the screw from the top and bottom, thereby ensuring that the fixing holes of the finishing layer will not be damaged.

[0016] Example 1 like Figure 1 The self-locking aerogel felt 2 composite board shown includes an aerogel felt 2, which can be made of aerogel felt, cement-based aerogel insulation board, or inorganic foamed aerogel insulation board. A first board 3 and a wrapping layer 1 are respectively provided on both sides of the aerogel felt 2. The first board 3 can be made of cement fiberboard, calcium silicate board, gypsum board, wood-plastic composite material (such as bamboo carbon fiber board), medium-density fiberboard, plywood, blockboard, etc. The wrapping layer 1 can be set as an air-barrier membrane, which can be made of building waterproof breathable membrane, geotextile, alkali-resistant fiberglass mesh composite geotextile, or skeleton non-woven fabric (skeleton type, purification type). Materials include formaldehyde-based, polyester fiber felt, PVC fiberglass coated felt, and cement fiberglass coated felt; the wrapping layer 1 can also be a mixed layer of reinforcing mesh and mixed mortar, wherein the reinforcing mesh is made of alkali-resistant fiberglass mesh cloth, which is wrapped around the side and edge of the aerosol felt 2 away from the first plate 3, and then mortar is applied to the surface of the reinforcing mesh to achieve the sealing performance of the mixed layer. The cross-sections of the air barrier membrane and the mixed layer are both U-shaped; in addition, the wrapping layer can first wrap the aerosol felt, and then connect the threaded cylinder and the screw, so that the threaded cylinder fixes the wrapping layer to the surface of the aerosol felt.

[0017] The first plate 3 is provided with a plurality of screws 31 and a plurality of fixing holes 32 for the screws 31 to be inserted. The screws 31 are of the same length and are vertically fixed to the first plate 3. The surface of the aerosol felt 2 is provided with a threaded cylinder 112. The inner ring of the threaded cylinder 112 is provided with threads that match the screws 31. After the screws 31 pass through the aerosol felt 2, they are threadedly connected to the threaded cylinder 112, thereby fixing the threaded cylinder 112 to the aerosol felt 2. The threaded cylinder 112 is provided with a base. The threaded cylinder 112 is inserted into the aerosol felt 2 and connected to the screws 31. Then the base abuts against the surface of the aerosol felt 2. After the screws 31 and the threaded cylinder 112 are connected, the wrapping layer 1 wraps the base of the threaded cylinder 112 to the surface of the aerosol felt 2, thereby fixing the threaded cylinder 112 to the aerosol felt 2.

[0018] Example 2 The difference between Example 2 and Example 1 is that the wrapping layer 1 in Example 2 is set as a second plate. The second plate has a number of positioning holes for the threaded cylinder 112 to pass through. The number of positioning holes is the same as the number of threaded cylinders 112 and they correspond one-to-one. In addition, the edge of the aerosol felt 2 is wrapped separately with an air-tight membrane or with a mixed layer of reinforcing mesh and mortar. The reinforcing mesh is made of alkali-resistant fiberglass mesh. The mortar is smoothed on the surface of the mesh to ensure the sealing of the edge of the aerosol felt 2.

[0019] The second panel serves as a connecting layer for connecting the base wall, while the first panel 3 serves as a finishing layer. The first panel 3, as the finishing layer, can be made of cement fiberboard, calcium silicate board, gypsum board, wood-plastic composite material (such as bamboo carbon fiber board), medium-density fiberboard, plywood, or blockboard. The second panel, as the connecting layer, can be made of cement fiberboard, calcium silicate board, bamboo carbon fiber board, KT board (made of polystyrene granules foam), PVC board (polyvinyl chloride), acrylic board (plexiglass), aluminum plate and aluminum composite panel, or PP board.

The sliding grooves 33 are connected to the fixing hole 32. The upper and lower sliding grooves 33 are symmetrically slidably connected with abutment blocks 34. A spring 35 is connected between the abutment blocks 34 and the sliding grooves 33. The spring 35 is used to push the abutment blocks 34 into the fixing hole 32. The upper and lower abutment blocks 34 are provided with inclined surfaces 341 on the opposite side. The inclined surfaces 341 on the opposite side of the upper and lower abutment blocks 34 are symmetrically opened with abutment grooves 342 for the screw head to be inserted.
