Description
Technical Field
[0001] The present application mainly relates to the field of building materials and construction technology, and in particular to an assembled building energy-saving wall. Background Art
[0002] At present, with the acceleration of urbanization, the construction industry has an increasing demand for efficient, environmentally friendly and quality-controlled construction methods. Although traditional cast-in-place concrete walls have high strength and durability, they have obvious shortcomings in terms of long construction period and serious environmental pollution. As an emerging construction technology, prefabricated building walls greatly shorten on-site construction time, improve construction efficiency and reduce environmental pollution through factory prefabricated components.
[0003] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.
[0004] Since the walls are assembled with various floor slabs, wall panels and insulation layers, people in the north need indoor heating in winter. When there is strong wind outside, the outdoor air pressure is lower than the indoor air pressure, causing the indoor gas to flow out through the wall. In the cold northern weather in winter, the indoor heat is lost out. Therefore, designing a prefabricated wall with good sealing performance is an urgent problem to be solved. Summary of the invention
[0005] In order to improve the sealing performance of prefabricated walls and reduce the outflow of indoor gas through the walls, the present application provides an assembled building energy-saving wall.
[0006] The present application provides an assembled building energy-saving wall that adopts the following technical solution:.
[0007] An assembled building energy-saving wall comprises a main wall, a cavity is formed in the main wall, a sealing sound insulation component is arranged in the cavity; the sealing sound insulation component comprises a sealing plate detachably connected to the main wall panel, the sealing plate is made of rubber material, a positioning groove is formed in the middle of the opposite side of the sealing plate, a sealing partition is inserted in the positioning groove, the sealing partition divides the cavity into a buffer cavity 1 and a buffer cavity 2, the sealing partition is made of a polyurethane sealing plate; a vent is formed on the side of the main wall close to the room, an adjustment component is arranged in the vent, and the adjustment component is used to control the indoor air volume to automatically enter and exit the cavity according to the outdoor wind force.
[0008] By adopting the above technical scheme, when the user uses it, when the wind is strong, the outdoor pressure is greater than the indoor pressure, and the indoor air enters the buffer chamber one through the vent, and the sealing plate and the sealing partition seal and separate the buffer chamber one and the buffer chamber two. The hardness range of the polyurethane sealing plate is wide, and it still has the elongation and resilience of rubber under high hardness. When the outdoor pressure is lower than the indoor pressure, the wind enters the buffer chamber one through the vent, and the wind pushes the sealing partition to deform in the direction of the buffer chamber two. The sealing partition separates the buffer chamber one and the buffer chamber two, reducing the gas in the buffer chamber one from entering the buffer chamber two. When the outdoor pressure decreases, the sealing partition pushes the wind to flow into the room, thereby returning the airflow in the buffer chamber one to the room through the vent, reducing the energy loss in the room.
[0009] Optionally, the adjustment component includes an adjustment plate arranged at the vent, the adjustment plate is slidably connected in the vent, the side wall of the adjustment plate abuts against the inner wall of the vent, an air outlet channel and an air inlet channel are opened in the adjustment plate, the air outlet channel is located above the air inlet channel, a plurality of air outlet grooves are opened on the top wall of the vent near the buffer chamber, and a plurality of air inlet grooves are opened at the bottom of the vent.
[0010] By adopting the above technical solution, when the user uses it, when the outdoor wind is strong and the indoor pressure is greater than the outdoor pressure, the indoor air pushes the adjustment plate to slide toward the outdoor direction, so that the air outlet channel and the air outlet groove on the top of the vent are connected, so that the indoor air enters the buffer chamber one through the air outlet channel and the air outlet groove. The sealing of the sealing baffle can reduce the gas entering the buffer chamber two. After the deformation of the sealing baffle and the reduction of the outdoor wind force, the sealing baffle rebounds, and the wind force pushes the adjustment plate to move toward the indoor direction, so that the gas in the sealed chamber one enters the room through the air inlet channel and the air inlet groove, thereby reducing the outflow of indoor air and reducing the loss of indoor energy in winter.
[0011] Optionally, a filter box is plugged into a side of the vent close to the room, and a sponge is placed in the filter box.
[0012] By adopting the above technical solution, when the user uses it, the sponge can block dust and the like from entering the vent, preventing dust from clogging the air inlet and outlet channels. The sponge does not affect air circulation, and the filter box is used to fix the sponge to prevent the sponge from being blown out of the vent by air pressure.
[0013] Optionally, a buffer groove is embossed on the sealing partition, and the buffer groove is in a corrugated, snake-shaped or long strip shape.
[0014] By adopting the above technical solution, when the user uses it, when the outdoor convection is large, after the indoor air enters the buffer chamber 1, the air can enter the buffer groove, and the wind force pushes the sealing baffle to undergo a certain deformation. The sealing baffle prevents the gas in the buffer chamber 1 from entering the buffer chamber 2, thereby reducing the loss of indoor gas to the outside and reducing the dissipation of indoor gas to take away the indoor energy.
[0015] Optionally, both the buffer chamber 1 and the buffer chamber 2 are provided with heat insulation boards, and the heat insulation boards are glass fiber boards.
[0016] By adopting the above technical solution, when the user uses it, the fiberglass board has excellent sound absorption and sound insulation performance, has excellent sound insulation effect, and has good thermal insulation performance, can keep the indoor temperature stable, the fiberglass board also has flame retardant properties, improves the fire resistance of the wall, and has high safety.

[0018] By adopting the above technical solution, when the user uses it, the insulation board can form an insulation layer to minimize the temperature difference between indoor and outdoor, thereby playing a role in insulation, which is conducive to improving the stability of indoor temperature and reducing the frequency of use of heating or air conditioning. It is mainly used to improve the insulation performance of buildings and reduce energy consumption. The structure of the insulation board can play a good sound insulation effect, avoid interference from external noise, and improve the indoor noise environment. The positioning net is used to fix the insulation board to the main wall to prevent the insulation board from falling off after being damaged.

[0020] By adopting the above technical solution, when the user uses it, the water-absorbent resin can absorb water. In the hot summer, as the temperature rises, the water on the heat sink evaporates. When the liquid water turns into gas, the water molecules need to absorb heat. In this process, the surrounding heat energy is absorbed by the water molecules, which reduces the temperature of the surrounding environment, thereby reducing the heat brought by the summer from being transferred to the room, playing a cooling role.
[0021] Optionally, a connecting plate and an installation plate are respectively provided at the top and bottom of the main wall body, and a slope one is provided on the side of the connecting plate away from the main wall panel, and slope one slopes downward from the middle of the connecting plate to both ends, and a slope two is provided on the side of the installation plate away from the main wall panel, and slope two slopes downward from both ends to the middle of the installation plate.

[0025] The following is combined with Figure 1-7 This application is described in further detail.
[0026] The present application embodiment discloses an assembled building energy-saving wall, referring to Figure 1 and Figure 2, including a main wall panel 1, an insulation layer structure 2 and a panel 3 arranged outside the insulation layer structure 2 are arranged on the outer side of the main wall body 1, a cavity 11 is opened in the main wall panel 1, a sealing sound insulation component 12 is arranged in the cavity 11, and the sealing sound insulation component 12 is assembled in the cavity 11; a connecting plate 13 and a mounting plate 14 are respectively arranged on the top and bottom of the main wall body 1, a slope 131 is opened on the side of the connecting plate 13 away from the main wall panel 1, and the slope 131 is inclined downward from the middle part of the connecting plate 13 to both ends, and a slope 2 141 is opened on the side of the mounting plate 14 away from the main wall panel 1, and the slope 2 141 is inclined downward from both ends of the mounting plate 14 to the middle part to form a V shape. When two adjacent main walls 1 are assembled, the slopes 131 and 141 of the mounting plate 14 and the connecting plate 13 can abut and cooperate with each other, so that the connection between the two main walls 1 is tighter, reducing the energy flowing out through the connecting seam of the main wall 1.
[0027] Reference Figure 2 and Figure 3 The inner wall of the cavity 11 is symmetrically provided with a plug-in slot 111, which is vertically arranged and located at the middle position of the cavity 11. The sealing sound insulation component 12 includes a sealing plate 121 plugged into the plug-in slot 111, and the sealing plate 121 is made of rubber material; a positioning groove 122 is provided in the middle of the opposite side of the sealing plate 121, and a sealing partition 123 is inserted into the positioning groove 122, and the sealing partition 123 divides the cavity 11 into a buffer cavity 124 and a buffer cavity 125. Punching cavity 2 126, buffer cavity 1 124 and buffer cavity 2 126 are all provided with insulation boards 125, and the insulation boards 125 are glass fiber boards. The glass fiber boards have excellent sound absorption and sound insulation properties, excellent sound insulation effects, and good heat insulation properties, and can maintain indoor temperature stability. The glass fiber boards also have flame retardant properties, which improve the fire resistance of the wall and have high safety. The glass fiber boards are mainly used for the main wall 1 to have the characteristics of heat preservation, heat insulation, flame retardancy and noise reduction.
[0028] Reference Figure 3 and Figure 4 , wherein the sealing partition 123 is made of a polyurethane sealing plate 121, which has a wide hardness range and still has the elongation and resilience of rubber at high hardness. And a buffer groove 1231 is pressed on the sealing partition 123. The figure shows that the buffer groove 1231 is corrugated, but it is not limited to the corrugated shape. The buffer groove 1231 can be arranged in a serpentine shape or in a long strip shape. When the outdoor convection is large, the indoor air enters the buffer chamber 1 124, and the air can enter the buffer groove 1231. The wind force pushes the sealing partition 123 to undergo a certain deformation. The sealing partition 123 prevents the gas in the buffer chamber 1 124 from entering the buffer chamber 2 126, thereby reducing the loss of indoor gas to the outside and reducing the indoor gas from dissipating and taking away the indoor energy.
[0029] Reference Figure 4 and Figure 5 A plurality of adjustment components 15 are arranged on the side of the main wall 1 close to the room, and a vent 16 is provided on the main wall 1. The adjustment component 15 includes an adjustment plate 151 arranged at the vent 16, and the adjustment plate 151 is slidably connected to the vent 16. The side wall of the adjustment plate 151 abuts against the inner wall of the vent 16, and an air outlet channel 152 and an air inlet channel 153 are provided in the adjustment plate 151. The air outlet channel 152 is located above the air inlet channel 153. A plurality of air outlet grooves 154 are provided on the top wall of the vent 16 close to the buffer chamber 1, and a plurality of air inlet grooves 155 are provided at the bottom of the vent 16. When the outdoor wind is strong, the indoor pressure is greater than the outdoor pressure. When the air in the room pushes the regulating plate 151 to slide toward the outdoor direction, the air outlet channel 152 is connected with the air outlet slot 154 at the top of the vent 16, so that the air in the room enters the buffer chamber 1 124 through the air outlet channel 152 and the air outlet slot 154. The sealing of the sealing partition 123 can reduce the gas from entering the buffer chamber 2 126. After the deformation of the sealing partition 123 and the reduction of the outdoor wind force, the sealing partition 123 rebounds, and the wind force pushes the regulating plate 151 to move toward the indoor direction, so that the gas in the sealed chamber 1 enters the room through the air inlet channel 153 and the air inlet slot 155, thereby reducing the outflow of indoor air and reducing the loss of indoor energy in winter. A filter box 156 is inserted on the side of the vent 16 close to the room, and a sponge 157 is placed in the filter box 156. The sponge 157 can prevent dust from entering the vent 16 without affecting the passage of air.
[0030] Reference Figure 6 and Figure 7 The insulation layer structure 2 includes an insulation board 21 arranged on the outer wall of the main wall 1. The insulation board 21 is a foam board. The insulation board 21 can form an insulation layer to minimize the temperature difference between indoor and outdoor, thereby playing a role in insulation, which is beneficial to improve the stability of indoor temperature and reduce the frequency of use of heating or air conditioning. It is mainly used to improve the insulation performance of buildings and reduce energy consumption. The structure of the insulation board 21 can achieve good sound insulation effect, avoid interference from external noise, and improve the indoor noise environment. The insulation board 21 is perpendicular to the main wall 1 on both sides with positioning nets 22. The positioning nets 22 are used to fix the insulation board 21 to the main wall 1 to prevent the insulation board 21 from falling off after being damaged.
[0031] A heat sink 23 and a felt 24 are sequentially arranged on the side of the heat preservation board 21 away from the main wall 1, and the panel 3 is arranged on the felt 24. The heat sink 23 is a water-absorbent resin, and a water pipe 25 is arranged on the top of the heat sink 23. The water pipe 25 is reserved with a pipe connected to a water source, and a water sprinkling hole is opened on the water pipe 25. The water sprinkling hole sprays water onto the heat sink 23. The water-absorbent resin can absorb water. In the hot summer, as the temperature rises, the water on the heat sink 23 evaporates. When the liquid water changes into gas, the water molecules need to absorb heat. In this process, the surrounding heat energy is absorbed by the water molecules, so that the temperature of the surrounding environment drops, thereby reducing the heat brought by the summer from being transferred to the room, playing a cooling role.
[0032] The implementation principle of an assembled building energy-saving wall in an embodiment of the present application is as follows: when installing the wall, first fix the bottom mounting plate 14, and then install the main wall 1 on the mounting plate 14. After the main wall 1 is fixed, insert the sealing plate 121 into the plug-in slot 111 of the main wall panel 1, and then insert the sealing partition 123 into the positioning slot 122, and then place the insulation board 125 in the buffer cavity 124 and the buffer cavity 2 126, and then install the insulation board 21, the heat dissipation plate 23, the linoleum felt 24 and the panel 3 again.
[0033] When the outdoor wind is strong, causing the indoor pressure to be greater than the outdoor pressure, the indoor air pushes the adjustment plate 151 to slide toward the outdoor direction, so that the air outlet channel 152 is connected with the air outlet groove 154 at the top of the vent 16, so that the indoor air can enter the buffer chamber 124 through the air outlet channel 152 and the air outlet groove 154. The sealing of the sealing baffle 123 can reduce the gas entering the buffer chamber 2 126. After the deformation of the sealing baffle 123 and the reduction of the outdoor wind force, the sealing baffle 123 rebounds, and the wind force pushes the adjustment plate 151 to move toward the indoor direction, so that the gas in the sealed chamber 1 enters the room through the air inlet channel 153 and the air inlet groove 155, thereby reducing the outflow of indoor gas and reducing the loss of indoor energy.
[0034] In addition, the insulation board 21 can minimize the temperature difference between indoor and outdoor, thereby playing a role in insulation, which is beneficial to improving the stability of indoor temperature and reducing the frequency of use of heating or air conditioning. It is mainly used to improve the thermal insulation performance of buildings and reduce energy consumption. The insulation board 125 further reduces the temperature difference between indoor and outdoor.
[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
