Description

Vacuum cavity composite wall

Technical Field

The utility model relates to a building wall body thermal insulation technology especially relates to a vacuum cavity composite wall.

Background

The wall body (especially the outer wall body) is an important part of the building envelope structure and has direct influence on the heat preservation and insulation performance of the building. In recent years, techniques for improving the thermal insulation performance of walls by using vacuum structures have been widely used. The existing vacuum wall body module is limited by the area of the vacuum cavity, the area is difficult to be enlarged, a plurality of modules are required to be assembled during installation, the installation process is complex, installation gaps exist, and the heat insulation performance is influenced.

For example, patent CN200820300974.1 discloses a wall module with glass vacuum tubes as thermal insulation material, in which the glass vacuum tubes as thermal insulation material are sealed in a cavity. Patent CN200720140926.6 discloses a composite vacuum external wall thermal insulation decorative wall board, which is provided with a vacuum layer (vacuum glass, etc.) between a decorative board and an internal connection board, and the thermal resistance of the wall body is improved by using the vacuum layer. Patent CN201910683926.8 discloses a prefabricated wallboard of concrete assembled, this wallboard includes double-deck vacuum insulation board layer, and every layer of vacuum insulation board layer is formed by the concatenation of polylith vacuum insulation panel. Patent CN201721717511.0 discloses an assembled composite vacuum insulation panel self preservation temperature wallboard, this wallboard embeds vacuum insulation panel equally, forms the integration wall body through splicing each other between the wallboard.

The wall bodies in the patent are all sandwich walls, the existing sandwich walls generally adopt hard heat insulation materials, then concrete is cast on two sides to be prefabricated into the wall bodies, or the wall bodies on two sides are built, and the heat insulation materials are filled in the middle. The difference between the above patents is that a vacuum layer is used as the insulating material layer.

However, the walls of the above patents must be made into modular wall panels due to the vacuum floor area constraints. If the area of the vacuum cavity is directly enlarged, firstly, the side walls of the vacuum cavity are easily attached to each other and deform, secondly, the volume of the vacuum cavity shrinks when the vacuum cavity is vacuumized, suction can be generated on an external structure, and therefore the external wallboard deforms.

Therefore, how to provide a vacuum cavity composite wall which can be made into a larger wall area without splicing becomes a problem to be solved urgently.

The housing 2 of the vacuum chamber 1 may be made of organic films such as polycarbonate film, polyethylene film, polyvinyl chloride film, polystyrene film, polyester film, or polypropylene film, or organic plates such as polycarbonate plate, polymethyl methacrylate plate, polyvinyl chloride plate, polystyrene plate, PETG plate, or resin plate. The vacuum cavity 1 made of materials such as organic films and organic plates has strong sealing performance, and the thickness and weight of the wall body can be reduced. When the volume of the vacuum chamber 1 is large, the deformation due to the vacuum suction force is more significant, and therefore, a support structure needs to be provided in the vacuum chamber 3. In the present embodiment, the inner circumferential side of the vacuum chamber 3 is filled with the inner frame 12, and the backup pad 13 is provided between the opposite side surfaces of the casing 2 to prevent the both sides of the vacuum chamber 3 from being attached together.

In this embodiment, the outer blade 5 is a cast-in-place plate, so the inner formwork 4 needs to be disposed between the outer blade 5 and the vacuum chamber 1 as a casting formwork, and after the outer blade 5 is poured, the inner formwork 4 is left in the wall body and is not removed.

If the vacuum cavity 1 and the inner template 4 are arranged in a close contact manner, the inner template 4 can be deformed by pressure difference when the vacuum cavity 1 is vacuumized. Therefore, a balance cavity 8 is reserved between the vacuum cavity 1 and the inner template 4, and when the vacuum is pumped, the balance cavity 8 is filled with the cavity inwards, so that the pressure difference borne by the inner template 4 is reduced, and the deformation of the inner template 4 is avoided.

In addition, the balance cavity 8 is arranged, so that the vacuum cavity 1 and the outer blade plate 5 can be separated, the outer blade plate 5 cannot deform due to the fact that the inner pressure difference and the outer pressure difference are borne, the difficulty of wall manufacturing is reduced, and the connection in enclosure is more convenient.

Further, in order to support the vacuum chamber 1 during installation to form the equilibrium chamber 8, a fixing pad 9 is provided between the vacuum chamber 1 and the inner mold plate 4. The fixed cushion blocks 9 can be arranged between each surface of the vacuum cavity 1 and the inner template 4, or only arranged between the front end surface and the rear end surface of the vacuum cavity 1 (namely the end surface with the largest area) and the inner template 4, and the deformation of the peripheral end surfaces is small due to the small area, so that the peripheral end surfaces can be directly and tightly abutted against the inner template 4.

For the evacuation of the vacuum chamber 1, an evacuation nozzle 6 can be provided on the housing 2. Correspondingly, an air exhaust slot hole 7 is arranged on the outer blade plate 5, one end of an air exhaust nozzle 6 is communicated with the vacuum cavity 3, and the other end of the air exhaust nozzle extends into the air exhaust slot hole 7. After the air exhaust is finished, the air exhaust nozzle 6 is closed, and the sealing mode of the air exhaust nozzle 6 is not limited in the application. Then the air-extracting slot hole 7 is sealed by the sealant 14.

Further, the equalizing chamber 8 may be communicated with the outside to completely eliminate the pressure difference formed in the inner mold plate 4 when the vacuum is drawn. Therefore, in a possible embodiment, the inner template 4 is provided with air supplement nozzles 10 on the side wall, the outer blade 5 is provided with air supplement slot holes 11, one end of the air supplement nozzle 10 is communicated with the balance cavity, and the other end extends into the air supplement slot holes 11. During vacuumizing, the air supplementing nozzle 10 is communicated with the atmosphere outside the wall body to supplement air in the balance cavity 8. After the vacuumizing is finished, the air supplement nozzle 10 is sealed, and the air supplement slot hole 11 is sealed by the sealant 14.

Preferably, the fixed cushion blocks 9 and the supporting cushion blocks 13 can be arranged correspondingly, and the vacuum cavity housing 2 arranged at the positions of the supporting cushion blocks 13 cannot be retracted, so that the fixed cushion blocks 9 arranged at the corresponding positions can ensure that the fixed cushion blocks 9 are always in close contact with the vacuum cavity 1, if the fixed cushion blocks 9 are arranged at other positions, the vacuum cavity housing 2 is retracted after vacuumizing, the fixed cushion blocks 9 are separated from the vacuum cavity 1, and the position of the vacuum cavity 1 in the wall body is not fixed.

The vacuum chamber 1 is not necessarily a single-layer structure, and as shown in fig. 4, a plurality of vacuum chambers 1 may be provided to form an integral structure. Each layer of vacuum cavity 1 is provided with an air suction nozzle 6 and a air supplement nozzle 10 independently.

and step two, respectively placing the air suction nozzle 6 and the air supplement nozzle 10 in an air suction groove sleeve and an air supplement groove sleeve, embedding the air suction groove sleeve and the air supplement groove sleeve in a pouring template of the outer blade plate 5, and then pouring and tamping the outer blade plate 5. After the casting and tamping are finished, an air exhaust slot 7 and an air supply slot 11 are formed in the air exhaust slot sleeve and the air supply slot sleeve. One end of the air suction nozzle 6 passes through the air suction slot hole 7 and the inner template 4 and then is communicated with the vacuum cavity 3 in the vacuum cavity 1, and the other end of the air suction nozzle 6 is left in the air suction slot hole 7; one end of the air supplement nozzle 10 penetrates through the air supplement slot hole 11 and the inner template 4 and then is communicated with the balance cavity 8, and the other end of the air supplement nozzle 10 is left in the air supplement slot hole 11;

and step three, vacuumizing the vacuum cavity 3 through the vacuumizing nozzle 6, and sealing the vacuumizing nozzle 6 after vacuumizing is finished. When the vacuum cavity 3 is vacuumized through the air suction nozzle 6, air is supplied through the air supply nozzle 10, and the air supply slot 11 is sealed by the sealant 14 after the vacuumization is finished.

During later maintenance, the sealant 14 can be pulled out, and whether the vacuum in the vacuum cavity 1 is insufficient or not is checked by the pressure gauge. If the vacuum is insufficient, the whole wall can be vacuumized again or replaced, so that the inspection and the control are realized.
