Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation, in particular to an integrated non-disassembly formwork structure for thermal insulation structures of ultra-low energy consumption buildings. Background Art

[0002] Vacuum Insulation Panel (VIP) and Graphite Polystyrene (GPS) are two common building insulation materials. VIP is relatively expensive, but its excellent insulation performance makes it suitable for applications with extremely high insulation requirements. Graphite Polystyrene, on the other hand, is less expensive and suitable for general building insulation needs.

[0003] The vacuum insulation composite insulation board is composed of a vacuum insulation board and a hardened protective shell. It can effectively avoid heat conduction caused by air convection, so that the thermal conductivity coefficient can be greatly reduced, meeting the high thermal insulation and ultra-low energy consumption requirements in the construction field.

[0004] When installing vacuum insulation composite insulation panels on building walls, holes are usually drilled in the hardened protective shell first, and then anchor bolts are inserted into the holes to fix them. Since the vacuum insulation panels are close to the edge of the hardened protective shell, the vacuum insulation panels are easily damaged during drilling, resulting in the loss of the insulation performance of the vacuum insulation composite insulation panels. In addition, the installation of a vacuum insulation composite insulation panel requires multiple anchor bolts for fixation, which not only reduces installation efficiency but also wastes installation materials. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated, non-disassembly formwork structure for thermal insulation structures used in ultra-low energy consumption buildings, so as to solve the above-mentioned defects caused by the prior art.

[0006] An integrated, non-disassembly formwork structure for an ultra-low energy consumption building insulation structure comprises a composite insulation board and a graphite polystyrene board. The composite insulation board and the graphite polystyrene board are staggered with their long sides and bonded together by flame-retardant polyurethane foam adhesive. The graphite polystyrene board is fixed to the building wall by a plurality of thermal break anchor bolts, and the thermal break anchor bolts are located at the joint between the two composite insulation boards spliced together.

[0007] Preferably, a plurality of fixing holes are provided on the edge of the graphite polystyrene plate, and the thermal break anchor bolts are correspondingly inserted into the fixing holes.

[0008] Preferably, the thickness of the composite insulation board is 40-60 mm, the thickness of the graphite polystyrene board is 50-80 mm, and the width of the composite insulation board and the graphite polystyrene board are both 0.4-0.8 m, and the length are both 1.4-3.5 m.

[0009] Preferably, the number of thermal break anchor bolts used is no less than 6 per square meter.

[0010] Preferably, the middle core material of the composite thermal insulation board is a vacuum insulation board, and all surfaces of the vacuum insulation board are covered with non-combustible thermal insulation slurry.

[0011] Preferably, the thickness of the non-combustible thermal insulation slurry is not less than 12.5 mm, and is provided with a glass fiber mesh and no less than 4 threaded steel reinforcement strips with a diameter of not less than 6 mm.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 6 As shown, an integrated non-disassembly formwork structure for an ultra-low energy consumption building insulation structure includes a composite insulation board 11 and a graphite polystyrene board 12. The composite insulation board 11 and the graphite polystyrene board 12 are staggered with their long sides and bonded together by flame-retardant polyurethane foam glue 13. The graphite polystyrene board 12 is fixed to the building wall by a plurality of thermal bridge anchor bolts 14, and the thermal bridge anchor bolts 14 are located at the joint between the two composite insulation boards 11 spliced together.

[0025] In this embodiment, the edges of the graphite polystyrene board 12 are provided with a plurality of fixing holes 12a, and the thermal break anchor bolts 14 are correspondingly inserted into the fixing holes 12a. During actual construction, the fixing holes 12a can be drilled on-site in the graphite polystyrene board 12 to facilitate fixing the insulation structure of the present application to the building wall via the thermal break anchor bolts 14, thereby improving installation efficiency and saving installation materials.

[0026] In this embodiment, the thickness of the composite insulation board 11 is 40 mm, and the thickness of the graphite polystyrene board 12 is 50 mm. The width of the composite insulation board 11 and the graphite polystyrene board 12 are both 0.6 m and 3 m respectively. The thickness of the insulation structure in this application is only 90 mm, while the thickness of traditional insulation materials is more than 250 mm.

[0027] In this embodiment, the number of thermal break anchor bolts 14 used is 6 per square meter. The thermal insulation structure in this application requires a certain number of thermal break anchor bolts 14 to be effectively fixed to the wall.

[0028] In this embodiment, the composite insulation board 11 comprises a vacuum insulation panel 111 as the central core material. All surfaces of the vacuum insulation panel 111 are coated with a non-combustible insulation slurry 112. Because the composite insulation board 11 comprises a vacuum insulation panel 111 as the central core material, perforations cannot be made to prevent the vacuum insulation panel 111 from damage, leakage, and failure, making bolt connection more complex.

[0029] In this embodiment, the non-combustible insulation slurry 112 is at least 12.5 mm thick and is provided with a glass fiber mesh 113 and at least four threaded steel reinforcement strips 114 with a diameter of at least 6 mm. These threaded steel reinforcement strips 114 are symmetrically arranged on the upper and lower surfaces of the vacuum insulation panel 111 and secured together with stainless steel wire. The glass fiber mesh 113 and threaded steel reinforcement strips 114 in the non-combustible insulation slurry 112 protect the vacuum insulation panel 111 and increase its flexural load.

[0030] This ultra-low energy consumption building insulation structure integrated non-disassembly formwork structure consists of a composite insulation board 11 and a graphite polystyrene board 12 staggered and bonded together by flame-retardant polyurethane foam glue 13. The thickness of this insulation structure is only 90mm, which not only saves materials but also reduces carbon emissions, but can achieve a thermal resistance value R greater than 5.71m 2 K / W, heat transfer coefficient value K is less than 0.175W / m 2 K, meeting the ultra-low energy consumption K value of 1.5-3W / m 2 Requirements between K.

[0031] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
