Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of thermal -insulated heat preservation, especially relates to vacuum heat insulation external wall heat preservation system. BACKGROUND

[0002] Compared with traditional buildings, one of the important features of green buildings is to achieve better use function with lower energy consumption, wherein increasing the thermal insulation performance of buildings becomes an important technical means to effectively reduce building energy consumption.

[0003] At present, the building external wall insulation material mainly takes ordinary insulation board and vacuum heat insulation board as the main part. The thermal insulation efficiency of ordinary insulation board is relatively limited, and the vacuum heat insulation board has the advantages of low thermal conductivity and excellent thermal insulation performance, which is in sharp contrast with traditional insulation materials. Under the premise of achieving the same insulation effect, the thickness of the vacuum heat insulation board is only one fifth of that of the ordinary insulation material, which not only effectively saves the building space, but also greatly reduces the material usage and construction cost, and shows good economy and practicability.

[0004] In the construction of traditional building external wall insulation, the installation of vacuum heat insulation board mainly adopts wet sticking process: first, the bonding mortar is applied on the surface of the base wall, and then the vacuum heat insulation board is pasted and fixed piece by piece. The system realizes the stability of the board through two-way constraint - the anchoring force of the mortar bonding layer in the vertical direction, and the plane constraint formed by the extrusion force between the boards in the horizontal direction. However, during long-term service, this construction system has significant quality risks: under the influence of thermal expansion and contraction effect caused by alternating environment temperature and humidity, freeze-thaw cycle and wind load, stress concentration is easy to occur at the bonding interface between the vacuum heat insulation board and the base layer, resulting in time-dependent decay of the bonding strength. When the interfacial bonding strength decreases to the critical threshold, the insulation system will have interlayer peeling phenomenon, not only causing a cliff-like drop in thermal insulation performance, but also possibly causing local or even overall falling accidents, which poses a serious threat to building safety and has major safety hazards such as high-altitude falling objects.

[0036] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will make further detailed description to the utility model combined with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0037] As Figures 1 to 4 The utility model discloses a base wall 1, the surface of base wall 1 is provided with vacuum heat insulation board 2 and support piece 3, support piece 3 is arranged below vacuum heat insulation board 2 correspondingly, support piece 3 can support vacuum heat insulation board 2, reduce the influence of its own gravity on the bonding strength, prolong the bonding life between it and base wall 1, prevent vacuum heat insulation board 2 from falling off from base wall 1.

[0038] Support piece 3 includes support plate 31 and connecting plate 32, support plate 31 is perpendicular to connecting plate 32, support plate 31 is abutted to the bottom of vacuum heat insulation board 2, connecting plate 32 is arranged below support plate 31, connecting plate 32 is fixedly connected to base wall 1, connecting plate 32 plays the role of fixing support piece 3 as a whole on base wall 1, and support plate 31 supports vacuum heat insulation board 2 abutted to it, reduces the influence of the gravity of vacuum heat insulation board 2 on the bonding strength, prevents separation and falling off from base wall 1, improves the heat preservation performance, prolongs the heat preservation life.

[0039] In the application, the surface of base wall 1 is bonded to vacuum heat insulation board 2 through polymer mortar 4.

[0040] As Figure 5 Vacuum heat insulation board 2 includes core plate 21 and barrier bag 22, and barrier bag 22 is wrapped on the outer side of core plate 21, as shown in the figure. Barrier bag 22 includes two barrier films 23 which are identical in structure and oppositely arranged, and the edges of the two barrier films 23 are fixedly connected. The two barrier films 23 are tightly attached to core plate 21 and wrap it. The surface of barrier bag 22 is sprayed with a sealing layer 24, and the sealing layer 24 wraps the connecting edges of the two barrier films 23.

[0041] Specifically, the barrier film 23 comprises an inner barrier layer 231 arranged close to the core plate 21 and an outer barrier layer 232 arranged outside the inner barrier layer 231, and a sealing layer 24 is sprayed on the surface of the outer barrier layer 232. By spraying the sealing layer 24 on the surface of the outer barrier layer 232, the sealing layer 24 can block the external air, preventing the external air from entering the inside of the barrier bag 22 from the outer barrier layer 232, and the sealing layer 24 also wraps the connecting edges of the two barrier films 23, which can prevent the external air from entering the inside of the barrier bag 22 from the connecting edges of the two barrier films 23, preventing the vacuum thermal insulation board 2 from swelling and bulging, prolonging the thermal insulation life, and avoiding the building wall decoration layer from falling off.

[0042] Preferably, the core plate 21 is a silica plate, which has the advantages of low density, high specific surface area and high porosity, and is a high-efficiency thermal insulation material.

[0043] The inner barrier layer 231 is an aluminum foil layer, which has excellent flexibility and moisture resistance, can tightly adhere to the core plate 21, effectively blocks the external moisture, prevents the water vapor from penetrating into the core plate 21, and avoids the influence of moisture on the thermal insulation performance of the silica plate; at the same time, the aluminum foil has high reflectivity to thermal radiation, can reflect most of the heat back, and further enhances the thermal insulation effect of the overall structure.

[0044] The outer barrier layer 232 is a glass fiber mesh layer, which has good wear resistance, corrosion resistance and low-temperature toughness, and the use of the glass fiber mesh layer for packaging the core plate 21 can improve the service life of the vacuum thermal insulation board 2, and even if the glass fiber mesh layer is damaged and leaks, the vacuum thermal insulation board 2 will not swell and bulge, avoiding the building wall decoration layer from falling off.

[0045] The sealing layer 24 is a film-forming aid layer sprayed on the surface of the outer barrier layer 232, and the thickness of the film-forming aid layer is not greater than 1mm. The film-forming aid can reduce the glass transition temperature of the polymer emulsion, so that the emulsion particles can also fuse at a lower temperature to form a continuous coating film. Therefore, it is helpful to form a protective film with good performance on the surface of the outer barrier layer 232 during film formation, and since the thickness is not greater than 1mm, it can play an effective role without affecting the overall structure or causing other adverse effects due to excessive thickness.

[0046] Moreover, the core plate 21 and the barrier film 23 are both rectangular, the size of the barrier film 23 is greater than that of the core plate 21, the length of the core plate 21 is 600mm, and the width of the core plate 21 is 200-600mm. The size of the core plate 21 needs to be changed according to the actual situation on site.

[0047] For example, Figure 2 , Figure 4 , Figure 6As shown in the drawings, the support plate 31 is fixed with an inner baffle 33 in the same plane as the connecting plate 32, and is fixed with an outer baffle 34 outside the inner baffle 33, and there is a gap between the inner baffle 33 and the outer baffle 34, and the support plate 31, the inner baffle 33 and the outer baffle 34 collectively wrap the vacuum heat insulation board 2.

[0048] When the construction is carried out, the bottom of the vacuum heat insulation board 2 is inserted between the inner baffle 33 and the outer baffle 34, and is clamped and fixed by the inner baffle 33 and the outer baffle 34, and is supported by the support plate 31.

[0049] Preferably, the top of the inner baffle 33 and the outer baffle 34 is arc-shaped in the vertical direction. By setting the top of each to be arc-shaped, when the vacuum heat insulation board 2 is clamped by the inner baffle 33 and the outer baffle 34, it can prevent the inner baffle 33 and the outer baffle 34 from causing wear to the vacuum heat insulation board 2, and prevent affecting the vacuum insulation effect of the vacuum heat insulation board 2.

[0050] The support plate 31, the inner baffle 33, the outer baffle 34 and the connecting plate 32 are integrally formed and have the same thickness, which is convenient to manufacture and reduces the cost.

[0051] In order to facilitate the fixing and connecting of the connecting plate 32 with the base wall 1, in the present application, the connecting plate 32 is provided with a nail hole 35, and the wall nail 5 passes through the nail hole 35 to fix and connect the connecting plate 32 with the base wall 1.

[0052] In use, first, the vacuum heat insulation board 2 is adhered to the base wall 1 by the polymer mortar 4, then the inner baffle 33, the outer baffle 34 and the support plate 31 on the support 3 are fixed at the bottom of the vacuum heat insulation board 2, and after the support plate 31 abuts against the vacuum heat insulation board 2 and the inner baffle 33 and the outer baffle 34 collectively clamp the vacuum heat insulation board 2, the connecting plate 32 is nailed to the base wall 1 by the wall nail 5.

[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
