Description

Technical Field

[0001] This utility model relates to the field of aerocondensed felt structure technology, specifically to a snap-fit ​​aerocondensed felt composite board structure. Background Technology

[0002] Aerogel, as a novel functional material with a three-dimensional nanoporous structure, has attracted much attention due to its excellent properties such as extremely low thermal conductivity, high porosity, and low density. Among them, aerogel felt is a flexible thermal insulation material made by combining nano-silica as the main substrate with carbon fiber, ceramic glass fiber, or pre-oxidized fiber felt through special processes. It has a very broad application space in the field of thermal insulation and has been widely used in many fields such as construction, industrial pipelines, and new energy.

[0003] However, when aerogel felt is applied to building interior insulation projects, dust is easily shed during use due to the nanoscale pores and loose structure on the surface of the aerogel felt. This not only adversely affects the stability of the material's insulation performance but also pollutes indoor air. Long-term exposure to such an environment may pose potential health risks to the respiratory system. To address these issues, we propose a snap-fit ​​aerogel felt structure. Utility Model Content

[0004] The present invention aims to provide a snap-fit ​​aerocondensed felt composite board structure to solve the problem that aerocondensed 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 snap-fit ​​type aerosol felt composite board structure, including aerosol felt, a panel and a wrapping layer disposed on both sides of the aerosol felt, and a snap fastener, the snap fastener including a snap head and a snap cap, the snap head passing through the panel and the aerosol felt in sequence and snapping with the snap cap.

[0006] The beneficial effects of this solution are as follows: by wrapping the aerosol felt with the wrapping layer, the aerosol felt and the fasteners can be bound together as a whole, preventing the aerosol felt from falling powder or breaking 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. It does not restrict the normal state of the aerosol felt, but also improves the tear resistance of the overall structure. The composite board can significantly shorten the assembly time and is suitable for mass production or rapid on-site construction.

[0007] Preferably, the panel has a first countersunk hole for mounting the card head, and after the card cap is connected to the card head, the wrapping layer wraps the card cap around the surface of the aerosol felt.

[0008] Preferably, the clamping head includes a top plate and a clamping rod vertically fixed to the top plate, the panel has a first countersunk hole for the top plate to be inserted, and the clamping cap includes a bottom plate and a clamping cylinder vertically fixed to the bottom plate.

[0009] Preferably, the wrapping layer is a mixture of an air-barrier membrane or a reinforcing mesh and mortar, and the cap is located between the wrapping layer and the aerosol felt or on the outside of the wrapping layer.

[0010] The beneficial effects are: the air-tight membrane has strong sealing performance, which can effectively protect the internal aerosol felt structure and prevent damage and particle escape. The mixed layer, which is a mixture of reinforcing mesh and mortar, can also protect the internal aerosol felt structure and prevent damage and particle escape.

[0011] Preferably, the wrapping layer has a U-shaped cross-section and wraps around the edge of the aerosol felt.

[0012] The beneficial effects are as follows: the U-shaped structure with a single-sided opening can cover the panel with the insulation layer on the U-shaped structure to ensure the fixation of the wrapping layer. At the same time, the panel can cover the opening of the wrapping layer, which facilitates on-site installation and customized design. It is suitable for indoor thermal insulation scenarios with high requirements for structural strength.

[0013] Preferably, the wrapping layer is set as an inner plate, and the edge of the aerosol felt is wrapped with a mixture of air-tight membrane or reinforcing mesh and mortar. The inner plate has a second countersunk hole for the insertion of the card cap.

[0014] The beneficial effect is that the edge wrapping can seal the sides of the aerosol felt, thereby reducing the problem of dust falling during the construction of building materials.

[0015] Preferably, the end of the clamp is provided with a crown-shaped cap, and the clamp is provided with a stepped structure corresponding to the crown-shaped cap.

[0016] The beneficial effects are as follows: when the crown cap is inserted into the clamping cylinder, the crown cap squeezes and deforms the clamping cylinder elastically. After the crown cap is fully inserted, the stepped structure of the clamping rod and the clamping cylinder are fully engaged, ensuring the stability of the engagement.

[0017] Preferably, the top plate is symmetrically hinged with abutment members on its upper and lower sides, and a torsion spring is provided between the abutment members and the top plate. The abutment members include a buffer plate for abutting against the clamping cylinder and a support plate for abutting against the first countersunk hole. The torsion spring is used to abut the buffer plate against the clamping cylinder.

[0018] Preferably, the angle between the buffer sheet and the support sheet is an obtuse angle.

[0019] The beneficial effects are as follows: the support plate will not protrude from the active cavity, but will be set horizontally at the edge of the top plate, while the buffer plate needs to protrude from the active cavity in the initial state so that the clamping cylinder can contact the buffer plate immediately. Therefore, in order to ensure that the clamping cylinder drives the support plate to rotate in real time through the buffer plate without delay, the included angle between the buffer plate and the support plate needs to be an obtuse angle.

Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: aerosol felt 1, panel 2, first countersunk hole 21, inner plate 3, clip 4, clip head 41, top plate 411, abutment part 4111, buffer piece 4112, support piece 4113, clip rod 412, crown cap 4121, clip cap 42, bottom plate 421, and clip cylinder 422.

[0022] Example 1 For example, 1- Figure 6 The figure shows a snap-fit ​​type aerogel felt 1 composite panel structure, including an aerogel station. The aerogel felt 1 can be made of aerogel felt, cement-based aerogel insulation board, or inorganic foamed aerogel insulation board. A panel 2 and an air-barrier membrane are respectively provided on both sides of the aerogel felt 1. The panel 2 can be made of cement fiberboard, calcium silicate board, gypsum board, wood-plastic composite material (bamboo charcoal fiberboard, etc.), medium-density fiberboard, plywood, blockboard, etc. The air-barrier membrane can be made of building waterproof and breathable membrane, geotextile, alkali-resistant fiberglass mesh composite geotextile, skeleton non-woven fabric (skeleton type, formaldehyde-purifying type), etc. Materials include polyester fiber felt, PVC fiberglass coated felt, and cement fiberglass coated felt. In addition, the panel 2 has a first countersunk hole 21. The clip 41 is inserted into the panel 2 through the first countersunk hole 21 and passes through the aerosol felt 1. The clip 41 includes a top plate 411 and a clip rod 412 that is vertically fixed to the top plate 411. The end of the clip rod 412 is fixedly connected to a crown cap 4121. The top plate 411 and the first countersunk hole 21 of the clip 41 are both round. The top plate 411 is tangent to the first countersunk hole 21. The depth of the first countersunk hole 21 is not less than the thickness of the top plate 411.

[0023] The cap 42 is also embedded in the aerosol felt 1. The cap 42 includes a base plate 421 and a cylinder 422 vertically fixed to the base plate 421. The cylinder 422 is inserted into the aerosol felt 1, and the base plate 421 abuts against the surface of the aerosol felt 1. The end of the clamping rod 412 is provided with a crown cap 4121. The cap 42 is provided with a stepped structure corresponding to the crown cap 4121. When the clamping head 41 and the cap 42 are clamped, the crown cap 4121 is engaged with the stepped structure. Then, an air-tight membrane is used to seal the connection. The aerosol felt 1 is wrapped around the side and edge away from the panel 2. The air-barrier membrane also wraps around the base plate 421 of the clip 42. The cross-section of the air-barrier membrane is U-shaped, which fixes the base plate 421 to the surface of the aerosol felt 1, thereby realizing the connection between the clip 4 and the panel 2 and the air-barrier membrane. When installing the composite panel structure of the aerosol felt 1 on the wall, the air-barrier side of the composite panel structure needs to be attached to the wall, the panel 2 is placed on the side away from the wall, and then the first countersunk hole 21 is smoothed with adhesive material.

[0024] Example 2 The difference between Example 2 and Example 1 is that the wrapping layer is a mixed layer of reinforcing mesh and mixed mortar. The reinforcing mesh is made of alkali-resistant fiberglass mesh cloth. The mesh cloth is wrapped around the side and edge of the aerosol felt 1 away from the panel 2. Then, mortar is applied to the surface of the reinforcing mesh to achieve the sealing performance of the mixed layer. The cross-section of the mixed layer is also U-shaped. After the cap and the head are connected, the wrapping layer wraps the cap around the surface of the aerosol felt, or the cap is located on the outside of the wrapping layer.

[0025] Example 3 The difference between Example 3 and Example 1 is that the wrapping layer is set as an inner plate 3, which is also a panel 2 structure. The inner plate 3 can be made of cement fiberboard, calcium silicate board, bamboo charcoal fiberboard, KT board (made of polystyrene granules foam), PVC board (polyvinyl chloride), acrylic board (plexiglass), aluminum plate and aluminum-plastic panel, PP board; In addition, the inner plate 3 has a second countersunk hole for the bottom plate 421 of the card cap 42 to be inserted. The second countersunk hole and the bottom plate 421 are both circular, and the bottom plate 421 is tangent to the second countersunk hole. The thickness of the bottom plate 421 is equal to the depth of the second countersunk hole. The edge of the aerosol felt 1 is wrapped separately with an air-barrier membrane. The air-barrier membrane is made of building waterproof breathable membrane, geotextile, alkali-resistant fiberglass mesh composite geotextile, skeleton non-woven fabric (skeleton type, formaldehyde purification type), polyester fiber thin felt, PVC fiberglass coated felt, cement fiberglass coated felt, etc.

[0026] Example 4 The difference between Example 4 and Example 3 is that the edge of the aerosol felt 1 is wrapped with a mixed layer of reinforcing mesh and mortar. The reinforcing mesh is made of alkali-resistant fiberglass mesh, and the mortar is smoothed on the surface of the mesh to ensure the sealing of the edge of the aerosol felt 1.

[0027] Example 5 The difference between Embodiment 5 and Embodiments 3 and 4 is that: the top plate 411 of the card head 41 is symmetrically arranged on both the upper and lower sides and each side has a movable cavity. An abutment member 4111 is rotatably connected within the movable cavity. The abutment member 4111 includes a buffer plate 4112 and a support plate 4113 fixedly arranged to each other. The included angle between the buffer plate 4112 and the support plate 4113 is an obtuse angle. A mounting shaft is provided within the movable cavity, and the abutment member 4111 is rotatably connected to the mounting shaft. A torsion spring connects the abutment member 4111 and the mounting shaft. The torsion spring pushes the buffer plate 4112 of the abutment member 4111 out of the movable cavity and against the side of the top plate 411 of the card cylinder 422 facing the card cylinder 422. Meanwhile, the support piece 4113 is located in the movable cavity. When the cap 42 is inserted through the second countersunk hole, the head 41 is embedded in the cylinder 422. The end of the cylinder 422 abuts against the buffer piece 4112. The buffer piece 4112 can prevent the collision between the cylinder 422 and the head 41. As the cap 42 is pressed in, the cylinder 422 of the cap 42 presses against the buffer piece 4112 in the opposite direction. At this time, the torsion spring is compressed and deformed. The buffer piece 4112 drives the support piece 4113 to push out from the movable cavity and abut against the inner wall of the first countersunk hole 21. The support pieces 4113 on the upper and lower sides push out at the same time, thereby reducing the load on the head 41 when the composite plate is suspended.
