Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a lightweight and low-energy composite thermal insulation board. Background Art

[0002] Thermal insulation materials are known as the "fifth energy source". Vigorously developing and actively promoting the application of thermal insulation materials is an effective energy-saving and environmental protection measure. At present, with the booming development of the energy-saving building materials industry, low-energy thermal insulation boards have been widely used in construction projects. The existing thermal insulation boards are usually in the structural form of single thermal insulation materials, which cannot take into account the different requirements for performance such as thermal insulation, fire protection, and compressive strength in different construction projects, and have poor applicability. At the same time, the energy-saving and thermal insulation performance of the existing thermal insulation boards needs to be further improved, and the bulk density needs to be further reduced.

[0003] A steel mesh is usually fixed on the outer surface of the thermal insulation board to facilitate the spraying operation of the mortar for the plastering layer and ensure the structural strength. In traditional thermal insulation boards, the steel mesh lacks a special fixing structure. Usually, the steel mesh is fixed by winding the steel mesh with iron wire and inserting it into the thermal insulation layer. The operation is not standardized, the fixing is not firm, the flatness of the steel mesh sheet is poor. Usually, the steel mesh sheet is close to the heat-insulating board near the position of the fixing wire, while the steel mesh sheet away from the fixing wire bulges out of the heat-insulating board, which is not conducive to the adhesion of the mortar during the spraying operation of the mortar. At the same time, the steel mesh sheet cannot be completely reserved within the spraying thickness, affecting the structural strength and flatness of the spraying layer. In addition, the fixing wire is inserted into the thermal insulation layer, damaging the integrity of the thermal insulation layer and reducing the wall protection and thermal insulation performance.

[0004] Based on this, developing a new type of lightweight and low-energy composite thermal insulation board for engineering practice is an urgent problem to be solved at present. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lightweight and low-energy composite thermal insulation board for the above problems, so as to solve the problems of single material of the existing thermal insulation board, poor applicability, the need to further improve the thermal insulation performance, and the need to further reduce the bulk density. At the same time, it solves the problem that the existing thermal insulation board lacks a reliable fixing device for the steel mesh sheet, resulting in poor flatness of the steel mesh sheet layout, and the fixing wire is inserted into the thermal insulation board, damaging the wall protection and thermal insulation performance.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0007] A lightweight and low-energy composite thermal insulation board includes a thermal insulation layer. A protective layer is arranged outside the thermal insulation layer. The protective layer and the thermal insulation layer are combined through bonding mortar or adhesive to form a composite thermal insulation board. The thermal insulation layer selects a board with a thermal conductivity lower than 0.04W / mK, and the protective layer selects a board with a compressive strength greater than 0.15Mpa.

[0008] Preferably, the heat insulation layer is in the form of a multi-layer board composite structure, which includes two or more of molded polystyrene board, graphite polystyrene board, extruded polystyrene board, graphite extruded board and polyurethane heat insulation board.

[0009] Preferably, the protective layer is made of non-combustible thermosetting composite polystyrene board or phenolic foam board.

[0010] Preferably, a steel mesh is arranged on the outer side of the protective layer, and a fixing device is arranged on the protective layer corresponding to the steel mesh. The fixing device includes a support seat, and a fixing claw for clamping the steel mesh is arranged on the support seat corresponding to the steel mesh.

[0011] Preferably, the fixing claw is connected to the support seat through a support rod. The fixing claw is an opening structure arranged at the front end of the support rod, forming a clamping groove for clamping the steel bars on the steel mesh. The width of the clamping groove is set corresponding to the diameter of the steel bars on the steel mesh.

[0012] Preferably, an anti-displacement protrusion is arranged at the top of the clamping groove corresponding to the steel bars of the steel mesh to limit the displacement of the steel bars in the clamping groove.

[0013] Preferably, the clamping groove is a cross-shaped notch structure arranged at the front end of the support rod. The cross-shaped notch structure corresponds to the intersection of the horizontal and vertical steel bars of the steel mesh, so that the intersection position of the steel bars of the steel mesh can be clamped in the cross-shaped notch.

[0014] Preferably, an external thread is provided at the root of the support rod, and a threaded hole is arranged on the support seat corresponding to the external thread of the support rod. The support rod is screwed on the support seat, so that the height of the support rod extending out of the wall can be adjusted.

[0015] Preferably, a reinforcing through hole is provided on the support seat.

[0016] Preferably, a connecting rod is arranged at the tail end of the support seat for connecting and fixing the support seat. The connecting rod penetrates through the protection board and is screwed on the tail seat.

[0017] The beneficial effects of the present utility model are as follows:

[0018] The utility model forms a composite insulation board by bonding an insulation layer and a protective layer with bonding mortar or an adhesive, and sets the insulation layer in a multi-level structure form. By combining different performance parameters of different insulation materials, a composite insulation layer that meets the expectations is formed to meet the different usage requirements of buildings. This makes the composite insulation board of the utility model have both good heat insulation performance and mechanical strength. On the premise of meeting the engineering requirements, the overall thickness can be reduced, thereby reducing the bulk density of the insulation board, improving the heat insulation performance of the insulation board, and reducing building energy consumption. At the same time, the smaller bulk density and thickness parameters facilitate production, storage, transportation and on-site installation operations. In addition, the thinner insulation board increases the usable floor area rate of the building.

[0019] In the utility model, the setting of the fixing device replaces the traditional operation mode of fixing steel wires by passing through a steel wire mesh with the help of a steel bar mesh, avoiding the situation that the fixing steel bars randomly penetrate and damage the insulation board, standardizing the fixing operation of the steel wire mesh, ensuring the flatness of the layout of the steel wire mesh, and improving the fixing strength of the steel wire mesh.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] AsFigures 1-5 As shown in Figures 1-5 , a lightweight and low-energy composite insulation board includes an insulation layer 10. A protective layer 20 is provided outside the insulation layer 10. The protective layer 20 and the insulation layer 10 are combined through bonding mortar or adhesive to form a composite insulation board. The insulation layer 10 is made of insulation materials with a relatively low thermal conductivity, and the protective layer 20 is made of protective materials with relatively high compressive strength and tensile strength, so that the composite insulation board has good heat insulation performance and mechanical strength. Preferably, the insulation layer 10 is made of insulation materials with a thermal conductivity lower than 0.04W / mK, and the protective layer 20 is made of protective materials with a compressive strength greater than 0.15Mpa to ensure that the composite insulation board has good heat insulation performance and mechanical strength at the same time. The composite insulation board in this embodiment can reduce the overall thickness on the premise of meeting the engineering requirements, thereby reducing the bulk density of the insulation board, facilitating production, storage, transportation and on-site installation operations. In addition, the thinner insulation board increases the usable floor area rate of the building.

[0029] As a preferred embodiment, the insulation layer 10 is in a multi-layer combined structural form, which includes two or more of expanded polystyrene (EPS), graphite polystyrene (GEPS), extruded polystyrene (XPS), graphite extruded board (GXPS) and polyurethane insulation board. Different performance parameters of different insulation materials are combined to form a composite insulation layer 10 that meets expectations to meet the different usage requirements of buildings. For example, expanded polystyrene has good mechanical strength, but its thermal conductivity parameter is not excellent, while graphite polystyrene has excellent thermal parameters, but its mechanical strength is low. Bonding expanded polystyrene and graphite polystyrene to form a composite insulation layer 10 can ensure both the energy-saving and heat-insulating properties and mechanical strength of the insulation layer 10, balance the performance parameters of the insulation layer 10, and facilitate cost control. During production, the insulation layer 10 can be configured with different hierarchical structures according to engineering requirements, taking into account both the heat insulation performance and mechanical properties of the insulation board while meeting the engineering requirements, and obtaining a structure of the insulation layer 10 with an overall thickness, bulk density and production cost meeting expectations.

[0030] The protective layer 20 is made of non-combustible board, preferably non-combustible thermosetting composite polystyrene board or phenolic foam board, so that the protective layer 20 has good flame retardant performance.

[0031] Preferably, as Figures 1-2As shown, a steel mesh 30 is arranged outside the protective layer 20, and the steel mesh 30 is fixed outside the protective layer 20 at a certain distance from the protective layer 20. When spraying mortar on-site, the steel mesh 30 will be used to carry the mortar, facilitating the mortar spraying operation. After the mortar spraying is completed, the steel mesh 30 will be reserved in the mortar, playing a role in strengthening the strength of the plaster layer. To facilitate the installation and fixation of the steel mesh 30, a fixing device 40 is provided on the protective layer 20 corresponding to the steel mesh 30. The fixing device 40 includes a support base 41, and fixing claws 42 are provided on the support base 41 corresponding to the steel mesh 30, enabling the steel mesh 30 to be clamped on the fixing claws 42, forming a supporting and fixing effect on the steel mesh 30, and at the same time enabling the steel mesh 30 to be arranged outside the protective layer 20 at a uniform interval distance. This embodiment replaces the traditional operation method of fixing the steel mesh 30 by passing fixing wires through the steel mesh 30, avoiding the situation where the fixed steel bars randomly penetrate and damage the insulation board, standardizing the fixing operation of the steel mesh 30, and ensuring the flatness of the layout of the steel mesh 30.

[0032] Preferably, as Figure 1 、 3 、Figure 4 shows, the fixing claw 42 is connected to the support base 41 through a support rod 43. The fixing claw 42 is an open structure provided at the front end of the support rod 43, forming a clamping groove 44 for clamping the steel bars on the steel mesh 30. The width of the clamping groove 44 is set corresponding to the diameter of the steel bars of the steel mesh 30.

[0033] Preferably, as Figure 3 shown, an anti-displacement protrusion 45 is provided at the top of the clamping groove 44 corresponding to the steel bars of the steel mesh 30 to limit the displacement of the steel bars in the clamping groove 44, enabling the steel mesh 30 to be firmly fixed in the clamping groove 44.

[0034] Furthermore, as Figure 4 shown, the clamping groove 44 is a cross-shaped notch structure provided at the front end of the support rod 43. The cross-shaped notch structure corresponds to the intersection points of the horizontally and vertically staggered steel bars of the steel mesh 30, enabling the intersection points of the steel bars of the steel mesh 30 to be clamped in the cross-shaped notch, further enhancing the fixing strength of the steel mesh 30.

[0035] Furthermore, as Figure 5As shown, an external thread is provided at the root of the support rod 43, and a threaded hole corresponding to the external thread of the support rod 43 is provided on the support base 41. The support rod 43 is screwed onto the support base 41, so that the height of the support rod 43 extending out of the wall can be adjusted, thereby realizing the adjustment of the support height of the steel mesh 30 to meet the construction requirements of different shotcrete thicknesses. When the requirement for the shotcrete thickness changes, rotate the support rod 43 so that the height of the clamping groove 44 meets the requirement for the shotcrete thickness, and the adjustment of the distance between the steel mesh 30 and the wall can be quickly completed, improving the operation convenience and expanding the applicable range.

[0036] Further, as Figure 2 , 4 shown, a reinforcement through hole 46 is provided on the support base 41. During the construction of the plaster layer, the sprayed mortar will fill into the reinforcement through hole 46, so that the support base 41 is firmly reserved in the plaster layer and firmly adhered to the protective layer 20.

[0037] As a preferred embodiment, as Figure 1 , 5 shown, a connecting rod 47 is provided at the tail end of the support base 41 for connecting and fixing the support base 41. The connecting rod 47 penetrates through the protective plate and is screwed onto the tail seat 48, ensuring the reliable installation of the fixing device 40.

[0038] The specific embodiments of the present invention disclosed above are only for illustration, but the present invention is not limited thereto. For those of ordinary skill in the art, any modifications made without departing from the principle of the present invention shall be considered as belonging to the protection scope of the present invention.
