Description

Technical Field

[0001] The present invention relates to the technical field of building walls, and more particularly to an environmentally friendly, energy-saving and heat-insulating wall. Background Art

[0002] In the energy consumption structure of a building throughout its life cycle, the operation stage (especially heating, air conditioning and ventilation) accounts for a considerable proportion and is a key link in energy conservation and emission reduction.

[0003] As the physical divider between indoor and outdoor environments, the thermal performance of the building envelope has a decisive impact on building energy consumption. Walls, the largest component of the building envelope, have a direct impact on the building's overall energy efficiency and indoor thermal comfort. Traditional non-insulated walls (such as solid brick walls and ordinary concrete walls) generally suffer from low thermal resistance, poor thermal inertia, and significant thermal bridging. These factors lead to significant indoor heat loss in winter and excessive heat intrusion in summer, forcing HVAC systems to operate at high loads for extended periods, resulting in significant energy waste and increased operating costs.

[0004] To this end, strategies have emerged in the market to change the installation method of the thermal insulation composite interlayer. For example, the exterior wall insulation construction method and thermal insulation exterior wall with patent number CN110805177B achieves thermal insulation of the exterior wall by installing thermal insulation modules on the exterior wall.

[0005] However, the external wall will aggravate the loss of thermal insulation performance due to the practical environment. In response to this, Jiangsu Nigao Technology Co., Ltd. has disclosed a polyurethane foam pouring wall insulation system with patent number CN115370026B. The polyurethane foam pouring wall insulation system uses the polyurethane foam insulation layer as part of the wall sandwich. It mainly relies on pouring polyurethane foam into the wall to form an insulation interlayer.

[0006] However, we also found that the filling performance of the insulation wall as mentioned above is not good. The main problem is that the filling insulation layer cannot fully contact the wall. Therefore, we consider using other insulation layers with built-in filling materials, such as placing the covering material in the wall and then filling it with insulation material. There are also some problems with this method. The covering material after filling may not be able to fully fill the wall, which will also cause a thermal bridge effect in the wall and affect insulation. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an environmentally friendly and energy-saving insulation wall with a filling insulation interlayer having sufficient deformation ability, which is easy to install and provides good protection for the insulation unit and high density.

[0014] The present invention is further configured as follows: the flow pressure balancer includes a diaphragm structure arranged between the covering part and the extension part, a plurality of flow channels arranged on the diaphragm structure, and a regulator arranged in each flow channel, and the regulator is configured so that when the fluid pressure of the covering part is greater than that of the extension part, the fluid of the covering part flows to the extension part through the regulator; when the flow pressure in the extension part is greater than the fluid pressure in the extension part, the fluid of the extension part flows to the covering part through the regulator.

[0015] The present invention is further configured as follows: the diaphragm structure also includes a plurality of membrane cavities arranged inside the diaphragm structure and enclosing fluid, an inner membrane plate arranged in each of the membrane cavities, and a plurality of buffer chambers arranged inside the diaphragm structure and used to extend the membrane cavity, and the buffer chamber is used to limit the maximum deformation of the thickness of the membrane cavity, the fluids in each of the membrane cavities are independent of each other, and the membrane cavity is configured so that when the inner wall of the membrane cavity is impacted by the fluid in the second insulation unit, it moves into the buffer chamber.

[0016] The present invention is further configured such that: the regulator is a double-chamber balancing valve or a breathing valve.

[0017] A construction method applicable to the above-mentioned environmentally friendly and energy-saving insulation wall, the specific construction method comprises the following steps: S1, preparing a sandwich insulation unit: preparing a plurality of sandwich insulation units with double-layer insulation units according to the above-mentioned structure for use;

[0018] S2. External wall masonry: clean the foundation surface, set the bottom waterproof layer, and place the pre-treated blocks on the mortar according to the required external wall thickness until the external wall and the interlayer insulation unit are consistent in height with the external wall;

[0019] S3. Place the sandwich insulation unit: Place the assembled sandwich insulation unit against the exterior wall. Before placement, place a first baffle on the exterior wall near the insulation composite interlayer. After the sandwich insulation unit is placed, place a second baffle on the other side of the insulation composite interlayer. Apply pressure until the second deformation space is filled, and then secure the baffles on both sides.

[0020] S4, inner wall masonry: along the length direction of the second baffle and at a position 10mm-20mm outward from the second baffle, carry out the masonry method of step S2, and carry out inner wall masonry, and the masonry height of the inner wall is consistent with the masonry height of the outer wall. After the inner wall masonry is completed, the first baffle and the second baffle are removed until the interlayer insulation unit is fully filled with the wall interlayer;

[0021] S5. Loop steps S2-S4, and build the outer wall on the original outer wall until the outer wall and the sandwich insulation unit are at the same height as the outer wall. Place the sandwich insulation unit against the outer wall. Before placement, place a first baffle on the side of the outer wall close to the insulation combination interlayer. After placing the sandwich insulation unit, place a second baffle on the other side of the insulation combination interlayer, and apply pressure until the second deformation space is filled. Fix the baffles on both sides, and build the inner wall along the length direction of the second baffle and at a position 10mm-20mm outward from the second baffle in the same way as step S2. The building height of the inner wall is kept consistent with the building height of the outer wall. After completing the inner wall building, remove the first baffle and the second baffle until the sandwich insulation unit fills the wall interlayer.

[0022] By adopting the above technical scheme, beneficial effects are achieved. 1. In the technical scheme of the present invention, a thermal insulation composite interlayer is placed in the building wall, and then the thermal insulation composite interlayer is composed of a number of interlayer insulation units. A single insulation unit includes a first insulation unit and a second insulation unit, and each of the second insulation units is placed in the middle of each first insulation unit. The first insulation unit is formed by a first coating material and includes a seal composed of an insulation fluid with a first fluid pressure; the second insulation unit is formed by a second coating material and includes a seal composed of a filling fluid with a second fluid pressure, and the second fluid pressure is set to be greater than the first fluid pressure. In order to ensure that the first insulation unit is effectively reset after installation, the first insulation unit has sufficient deformation space so that it can be deformed between it and the wall. Better automatic fitting, and the first and second insulation units form an inner and outer double-layer insulation structure. The double-layer support structure can ensure that a good strong support structure foundation is formed in the wall, avoiding the need for a single structure to be supported by direct filling, resulting in poor fitting with the wall, or causing greater wear between the insulation unit and the wall, thereby affecting the service life. During installation, the first insulation unit is pressurized, and the fluid pressure in the first insulation unit is used to squeeze the second insulation unit. After the first insulation unit is released, the second insulation unit will reset because the fluid pressure is greater than the first insulation unit, thereby making the first and second insulation units more comprehensive in filling the wall, reducing the generation of thermal bridge effect, thereby greatly ensuring the insulation effect and greatly improving practicality;

[0023] 2. The second thermal insulation unit is configured to include at least one portion surrounded by the first thermal insulation unit, and the surrounded portion of the second thermal insulation unit is configured to be disconnected from the first thermal insulation unit, so that when the first thermal insulation unit is subjected to pressure, the portion of the second thermal insulation unit surrounded by the first thermal insulation unit is squeezed by the increase in pressure, so as to reduce the fluid pressure in the first thermal insulation unit, thereby facilitating the installation of the sandwich thermal insulation unit and forming a reset space, and the second thermal insulation unit has a second deformation space when squeezed by the first thermal insulation unit. The second deformation space is specifically the inner space surrounded by the second thermal insulation unit, so as to form an inner buffer space when the flow pressure in the second thermal insulation unit increases, and of course also to form an effective reset when the pressure of the first thermal insulation unit is subsequently released;

[0024] 3. In order to adjust the speed of the fluid entering the extension part according to the pressure change when the covering part is under pressure, the regulator can adjust the flow rate according to the pressure change of the first insulation unit, thereby balancing the pressure on both sides of the diaphragm structure of the second insulation unit, thereby reducing the impact on the extension part of the second insulation unit. At the same time, it can also improve the protection of the first insulation unit during installation and reduce the impact of the squeezing force of the wall;

[0025] 4. In the construction method of the present invention, based on the different pressure values ​​of the fluid in the first insulation unit and the fluid in the second insulation unit, a pressure difference is formed by the first insulation unit squeezing the second insulation unit after being subjected to pressure, and the baffle is fixed until the wall construction is completed. The baffle is then removed to allow the second insulation unit to self-regulate. Because sufficient second deformation space is left for the second insulation unit, the first insulation unit still has good deformation ability when subjected to gradually increasing pressure. While ensuring the filling of the space between the walls, it can also ensure the protection of the first insulation unit and reduce damage. In addition, because the fluid pressure in the second insulation unit is greater than the fluid pressure in the first insulation unit, the recovery ability of the first insulation unit is stronger.

[0026] At the same time, in the construction method of the embodiment of the present invention, a segmented masonry method is adopted to ensure that the interlayer insulation unit can fit better with the wall, thereby greatly reducing the generation of thermal bridge effect and greatly improving the insulation effect, which is easy to promote.

Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0034] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0035] An environmentally friendly and energy-saving thermal insulation wall, comprising a thermal insulation composite interlayer, the thermal insulation composite interlayer being placed in a building wall, the thermal insulation composite interlayer comprising a first thermal insulation unit 10, which is formed by encapsulating a thermal insulation fluid having a first fluid pressure with a first coating material and sealing the resultant;

[0036] The second heat preservation unit 11 is formed by encapsulating a filling fluid having a second fluid pressure with a second encapsulating material and sealing the filling fluid;

[0037] The second fluid pressure is greater than the first fluid pressure, and each of the second heat-insulating units 11 is placed between the first heat-insulating units 10 to form a sandwich heat-insulating unit 12. The first heat-insulating unit 10 has a first deformation space 101 after being subjected to force toward the second heat-insulating unit 11, and the second heat-insulating unit 11 has a second deformation space 110 after being subjected to force.

[0038] The thermal insulation composite interlayer is configured to pre-extrude the first thermal insulation unit 10 after the outer wall is built, until the first thermal insulation unit 10 squeezes the second thermal insulation unit 11 to form a first deformation space 101 and a second deformation space 110, both of which are compressed. After the inner wall is built, the compressed first and second deformation spaces are released, so that the interlayer thermal insulation unit 12 fills the interlayer between the building walls.

[0039] In the technical solution of the present invention, a thermal insulation composite interlayer is placed in the building wall, and then the thermal insulation composite interlayer is composed of a plurality of interlayer insulation units 12, a single insulation unit includes a first insulation unit 10 and a second insulation unit 11, and each second insulation unit 11 is placed between each first insulation unit 10, the first insulation unit 10 is formed by a first coating material and includes a seal of an insulation fluid with a first fluid pressure; the second insulation unit 11 is formed by a second coating material and includes a seal of a filling fluid with a second fluid pressure, and the second fluid pressure is set to be greater than the first fluid pressure, in order to ensure that the first insulation unit 10 is effectively reset after installation, the first insulation unit 10 has sufficient deformation space so that it can automatically fit better with the wall 1, In addition, the first and second insulation units form an inner and outer double-layer insulation structure. The double-layer support structure can ensure that a good strong support structure foundation is formed in the wall 1, avoiding the need for a single structure to be supported by direct filling, resulting in a poor fit between the wall 1, or affecting the greater wear between the insulation unit and the wall 1, thereby affecting the service life. During installation, the first insulation unit 10 is subjected to pressure, and the fluid pressure in the first insulation unit 10 is combined to squeeze the second insulation unit 11. After the first insulation unit 10 is released, the second insulation unit 11 will be reset because the fluid pressure is greater than the first insulation unit 10, thereby making the filling effect of the first and second insulation units on the wall 1 more comprehensive, reducing the generation of thermal bridge effect, thereby greatly ensuring the insulation effect and greatly improving practicality.

[0040] The second insulation unit 11 includes at least one portion surrounded by the first insulation unit 10, and the surrounded portion of the second insulation unit 11 is not connected to the first insulation unit 10, so that when the first insulation unit 10 is subjected to pressure, the increase in pressure squeezes the portion of the second insulation unit 11 surrounded by the first insulation unit 10 to reduce the fluid pressure in the first insulation unit 10, thereby facilitating the installation of the interlayer insulation unit 12 and forming a reset space, and the second insulation unit 11 has a second deformation space 110 when squeezed by the first insulation unit 10. The second deformation space 110 is specifically the inner space surrounded by the second insulation unit 11, in order to form an inner buffer space when the flow pressure in the second insulation unit 11 increases, and of course, to form an effective reset when the pressure of the first insulation unit 10 is subsequently released.

[0041] The present invention is further configured such that the second insulation unit 11 includes a covering portion 21 covered by the first insulation unit 10 and an extension portion 22 arranged between each connected first insulation unit 10, the covering portion 21 and the extension portion 22 are both filled with filling fluid, the covering portion 21 and the extension portion 22 are connected to each other, and a flow pressure balancer 3 is provided between the covering portion 21 and the extension portion 22, the flow pressure balancer 3 is used to form a buffer for the fluid pressure in the covering portion 21 after being subjected to the fluid pressure in the first insulation unit 10, so that the covering portion 21 will adjust the speed of the fluid entering the extension portion 22 according to the change in pressure when being pressurized, then the flow pressure balancer 3 can form different flow rate adjustments according to the change in pressure of the first insulation unit 10, thereby reducing the impact on the extension portion 22 of the second insulation unit 11, and at the same time, it can also improve the protection of the first insulation unit 10 during installation and reduce the extrusion force from the wall 1.

[0042] In an embodiment of the present invention, the flow pressure balancer 3 is configured to include a diaphragm structure 30 provided between the covering portion 21 and the extension portion 22, a plurality of flow channels 31 provided on the diaphragm structure 30, and a regulator 32 provided in each flow channel 31. Then, because the regulator 32 is configured so that when the fluid pressure of the covering portion 21 is greater than that of the extension portion 22, the fluid of the covering portion 21 flows to the extension portion 22 through the regulator 32; when the flow pressure in the extension portion 22 is greater than the fluid pressure in the extension portion 22, the fluid of the extension portion 22 flows to the covering portion 21 through the regulator 32, at this time, the pressure of the covering portion 21 can be adjusted according to the flow pressure change of the first heat preservation unit 10. 21 of the fluid flows, and the flow pressure on the extended portion 22 is increased. It is worth noting that the second deformation space 110 surrounded by the second insulation unit 11 needs to cover the maximum deformation range of the second insulation unit 11 when the first insulation unit 10 is subjected to the maximum extrusion pressure, that is, after the second insulation unit 11 is subjected to the maximum flow pressure, if the first insulation unit 10 continues to apply pressure, then the second insulation unit 11 will form an extrusion of the second deformation space 110 inward to provide the first insulation unit 10 with a second deformation space 110 after being pressurized. Therefore, the deformation range reached by the second deformation space 110 needs to meet the second deformation space 110 brought about by the above-mentioned extrusion pressure.

[0043] In this embodiment, the diaphragm structure 30 includes a plurality of membrane cavities 33 arranged inside the diaphragm structure 30 and enclosing fluid, an inner membrane plate 330 arranged in each of the membrane cavities 33, and a plurality of buffer chambers 34 arranged inside the diaphragm structure 30 and used to extend the membrane cavity 33, and the buffer chamber 34 is used to limit the maximum deformation of the thickness of the membrane cavity 33. The fluids in each of the membrane cavities 33 are independent of each other. The membrane cavity 33 is configured so that when it is impacted by the fluid in the second insulation unit 11, the inner wall of the membrane cavity 33 moves toward the buffer chamber 34 and forms a first buffer for the impact of the fluid, thereby improving the overall installation stability of the insulation interlayer unit.

[0044] It is worth mentioning that the flow channel 31 and the regulator 32 in the diaphragm structure 30 are used to pass fluid and constant pressure, while the membrane cavity 33, the inner membrane plate 330 and the buffer chamber 34 rely on the fluid filling in the membrane cavity 33 to form a pressurized space. When the fluid in the coating part 21 is pressurized and wants to enter the extension part 22 through the regulator 32, the impact of the fluid in the coating part 21 can be reduced through the membrane cavity 33 structure. The membrane cavity 33 is cooperated with the buffer chamber 34 on its peripheral side to achieve pressure buffering of the fluid in the membrane cavity 33 and realize radial transfer of pressure.

[0045] A construction method applicable to the above-mentioned environmentally friendly and energy-saving insulation wall, the specific construction method comprises the following steps: S1, preparing a sandwich insulation unit 12: preparing a plurality of sandwich insulation units 12 with double-layer insulation units according to the above-mentioned structure for use;

[0046] S2, exterior wall masonry: clean the foundation surface, set the bottom waterproof layer, and place the pre-treated blocks on the mortar according to the required exterior wall thickness until the exterior wall and the interlayer insulation unit 12 are at the same height as the exterior wall;

[0047] S3. Place the sandwich insulation unit 12: Place the assembled sandwich insulation unit 12 against the exterior wall. Before placement, place a first baffle on the exterior wall near the insulation composite interlayer. After the sandwich insulation unit 12 is placed, place a second baffle on the other side of the insulation composite interlayer. Apply pressure until the second deformation space 110 is filled, and then secure the baffles on both sides.

[0048] S4, inner wall masonry: along the length direction of the second baffle and at a position 10mm-20mm outward from the second baffle, carry out the masonry method of step S2, and carry out inner wall masonry, and the masonry height of the inner wall is consistent with the masonry height of the outer wall. After the inner wall masonry is completed, the first baffle and the second baffle are removed until the interlayer insulation unit 12 is filled with the interlayer of the wall 1;

[0049] S5. Loop steps S2-S4, and build the outer wall on the original outer wall until the outer wall and the sandwich insulation unit 12 are at the same height as the outer wall. Place the sandwich insulation unit 12 against the outer wall. Before placement, place a first baffle on the side of the outer wall close to the insulation combination interlayer. After placing the sandwich insulation unit 12, place a second baffle on the other side of the insulation combination interlayer, and apply pressure until the second deformation space 110 is filled. Fix the baffles on both sides, and build the inner wall along the length direction of the second baffle and at a position 10mm-20mm outward from the second baffle in the same way as step S2. The building height of the inner wall is kept consistent with the building height of the outer wall. After completing the inner wall building, remove the first baffle and the second baffle until the sandwich insulation unit 12 fills the wall 1 interlayer.

[0050] In the construction method of the present invention, according to the different pressure values ​​of the fluid in the first insulation unit 10 and the fluid in the second insulation unit 11, a pressure difference is formed by squeezing the second insulation unit 11 by the first insulation unit 10 after being subjected to pressure, and the pressure difference is fixed by a baffle until the construction of the wall 1 is completed, and the baffle is removed to allow the second insulation unit 11 to form self-regulation. Because sufficient second deformation space 110 of the second insulation unit 11 is reserved, the first insulation unit 10 still has good deformation ability when subjected to gradually increasing pressure. While ensuring the filling of the space between the walls 1, it can also ensure the protection of the first insulation unit 10 and reduce damage. In addition, because the fluid pressure in the second insulation unit 11 is greater than the fluid pressure in the first insulation unit 10, the recovery ability of the first insulation unit 10 is stronger.

[0051] At the same time, in the construction method of the embodiment of the present invention, a segmented masonry method is adopted to ensure that the interlayer insulation unit 12 can fit better with the wall 1, thereby greatly reducing the generation of thermal bridge effect and greatly improving the insulation effect, which is easy to promote.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
