Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a vacuum insulation board for building used to reduce the cold and hot bridge effect. Background Art

[0002] Vacuum insulation panel is a kind of vacuum insulation material, which can effectively avoid heat transfer caused by air convection and greatly reduce the thermal conductivity. Vacuum insulation panel is mainly composed of core material, barrier film and getter, and the core material is the key factor that determines the insulation performance of vacuum insulation panel. Common core materials include particle core material, foam core material, fiber core material and composite core material, among which fiber core material has the advantages of low density, small diameter and low thermal conductivity.

[0003] However, in actual use, the size of the traditional vacuum insulation panels is fixed, but the size of the building is not fixed. In order to insulate buildings of various sizes, the vacuum insulation panels inevitably need to be spliced. The insulation effect in the middle of the finished vacuum insulation panel is completely fine, but since the splicing position is made up of two groups of vacuum insulation panels spliced ​​together, a gap will be generated in the middle. Even though these gaps are usually sealed with structural adhesives, the inside of the vacuum insulation panel is in a vacuum state, and the joints of the vacuum insulation panels are in direct contact with each other, resulting in inconsistent insulation effects at the edge and center of the vacuum insulation panel, and a serious cold and hot bridge effect. Therefore, a building vacuum insulation panel with reduced cold and hot bridge effect is proposed. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a vacuum insulation panel for building that reduces the cold and hot bridge effect, so as to solve the technical problems raised in the above background.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] A vacuum insulation panel for building that reduces the effect of cold and heat bridges, such as Figures 1 to 7As shown, it includes an inner barrier film bag layer 100, a sealing assembly 200 is installed on the inner side of the inner barrier film bag layer 100, a core material layer 300 is arranged on the side of the sealing assembly 200 away from the inner barrier film bag layer 100, a supporting isolation assembly 400 is installed on the end of the core material layer 300 away from the sealing assembly 200, an outer barrier film bag layer 500 is arranged on the end of the supporting isolation assembly 400 away from the core material layer 300, a vacuum hole penetrating to the inner side of the inner barrier film bag layer 100 is opened on the outer side, and a sealing plug 600 is arranged inside the vacuum hole;

[0030] The inner barrier film bag layer 100 and the adjacent inner barrier film bag layer 100 are connected by a sealant at their contact gaps, and the outer barrier film bag layer 500 and the adjacent outer barrier film bag layer 500 are connected by a sealant at their contact gaps;

[0031] When the staff are splicing and installing the vacuum insulation panels, they first use sealants and insulation materials to fix the sides of a group of vacuum insulation panels to the building, and ensure that there is no gap between the building and the sides of the vacuum insulation panels. Then, sealants are applied to the other sides of the vacuum insulation panels, and the other vacuum insulation panels are placed in order and according to the needs. It should be noted that when applying sealants, the surface must be cleaned first, and the surface of the building must also be cleaned at the contact position with the building, and the building and the insulation material must be fixed first. Finally, the insulation material is fixed to the vacuum insulation panel to reduce the heat transfer at the contact position between the building and the vacuum insulation panel. At the same time, the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 need to be glued in the middle when they are in contact with other materials, and ensure that after the connection, there is glue overflow on both sides of the edge of the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500, and the glue overflow needs to be uniform to prevent leakage due to insufficient glue overflow when the vacuum insulation panel joint position is vacuumed later;

[0032] After the staff has completed the installation of the required positions and confirmed that each set of overflow glue has dried, the staff will open the sealing plug and use multiple sets of vacuum machines to vacuum the connection positions of the vacuum insulation panels;

[0033] The sealing assembly 200 includes a transverse limiting frame 210 clamped with the inner barrier film bag layer 100, and longitudinal limiting frames 220 are installed on both sides of the transverse limiting frame 210, and the top and bottom ends of the longitudinal limiting frame 220 are installed with transverse limiting frames 210;

[0034] In the above structural design, sealing components 200 are arranged between the inner barrier film bag layer 100 and the core material layer 300, and between the core material layer 300 and the outer barrier film bag layer 500, so that the center position of the vacuum insulation panel can be vacuumed in the factory first, and the splicing position is vacuumed after the vacuum insulation panel is installed on site by splicing the vacuum insulation panels. This reduces the problem of the vacuum insulation panel being too large to be transported during transportation, and the subsequent vacuuming of the gap position reduces the cold and hot bridge effect at the joints of the vacuum insulation panels.

[0035] Please refer to Figures 4 to 6 As shown, the transverse limit frame 210 includes an arc rod 211 connected to the end of the core material layer 300, and guide limit columns 212 are installed on both sides of the arc rod 211. The end of the arc rod 211 away from the core material layer 300 is fixedly connected to a connecting horizontal plate 214, and one end of the connecting horizontal plate 214 is located on one side of the guide limit column 212 and is installed with a limit connection sleeve 213. Limit grooves 215 are provided on both sides of the connecting horizontal plate 214, and the end of the connecting horizontal plate 214 away from the arc rod 211 is equipped with a first connecting vertical plate 216;

[0036] Please refer to Figure 6 As shown, the longitudinal limit frame 220 includes a limit strip 222 that is clamped in the limit groove 215, a sealing plate 221 is installed on the side of the limit strip 222 away from the limit groove 215, and a second connecting vertical plate 223 is installed on the side of the sealing plate 221 away from the limit strip 222;

[0037] Please refer to Figure 4 and Figure 5 As shown, the arc rod 211 and an adjacent group of arc rods 211 are distributed in a mirror-symmetrical manner to form a card and a piece, and the card and the piece are distributed in an equidistant array along the length direction of the connecting horizontal plate 214, and the limiting connecting sleeve 213 is distributed in an equidistant array along the length direction of the connecting horizontal plate 214;

[0038] Due to the integral plate structure of the vacuum insulation panel, it is not only necessary to isolate the cold and hot bridge effect, but also has certain requirements on the material strength itself. When the vacuum insulation panel is evacuated, due to the inconsistent internal and external pressures, the hardness of the surface material of the vacuum insulation panel is a great test. However, with the increase of hardness, the cost of many materials will also increase. Therefore, the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 are supported by supporting the isolation component 400 in conjunction with the sealing component 200, and the sealing component 200 is located at the edge position of the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500, and supports the weak positions of the edges of the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500, thereby preventing the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 from deformation.

[0039] Please refer to Figure 2 , Figure 3 and Figure 7 As shown, both sides of the core material layer 300 are equipped with support isolation components 400, and the inner barrier film bag layer 100 and the outer barrier film bag layer 500 are respectively connected to the two groups of support isolation components 400 on the side away from the core material layer 300. The support isolation components 400 include a first hollow insulation rod 410 sleeved with the limiting connection sleeve 213, and the outer wall of the first hollow insulation rod 410 is equipped with a connecting strip 420, and the side of the connecting strip 420 away from the first hollow insulation rod 410 is equipped with a support insulation strip 430, and the two sides of the support insulation strip 430 are equipped with connecting strips 420, and the side of the support insulation strip 430 away from the first hollow insulation rod 410 is equipped with a second hollow insulation rod 440;

[0040] The inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 are supported at the center by supporting the isolation assembly 400 to prevent the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 from having too large an area at the center and deformation or pits caused by inconsistent internal and external pressures. In addition, since the first hollow insulation rod 410 is circular as a whole, the contact area with the outer wall of the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500 is small, which not only maintains its good support, but also reduces the influence of temperature among the inner barrier film bag layer 100, the core material layer 300 and the outer barrier film bag layer 500.

[0041] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
