Description

Technical Field

[0001] This application relates to the field of precast concrete walls, and particularly to a precast concrete wall with earthquake resistance and heat insulation. Background Art

[0002] With the development of modern building technology, wall materials not only need to meet the basic load-bearing and enclosure functions, but also need to have good heat insulation and earthquake resistance performance. Precast concrete walls are widely used because of their advantages such as easy construction and controllable quality. Precast concrete walls are mainly processed in prefabrication factories or construction sites for building assembly, aiming to improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the building construction period. However, the earthquake resistance and heat insulation performance of traditional precast concrete walls still need to be improved.

[0003] Currently, in order to improve the heat insulation performance of walls, the conventional method is to add heat insulation material layers inside and outside the walls, such as polystyrene foam boards, etc. In order to improve the earthquake resistance performance, usually the thickness of the wall is increased or higher-strength concrete is used. However, these methods often lead to an increase in wall cost and construction difficulty. The earthquake resistance and heat insulation solutions in the prior art are often isolated and do not form an integrated system. In addition, adding heat insulation layers and earthquake resistance measures may lead to an increase in wall thickness, which not only affects the usable space of the building, but also may increase the building cost. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, this application provides a precast concrete wall with earthquake resistance and heat insulation, which has the advantages of effectively improving the earthquake resistance and heat insulation performance and construction efficiency of the precast concrete wall without increasing the wall thickness.

[0005] To sum up, this application provides the following technical solution: A precast concrete wall with earthquake resistance and heat insulation, including a first concrete wall panel, a second concrete wall panel, and a heat insulation layer arranged between the first concrete wall panel and the second concrete wall panel. A plurality of connecting members are arranged on the side wall of the first concrete wall panel.

[0006] The connecting member includes a connecting block and a connecting sleeve. The connecting block is arranged on the side wall of the first concrete wall panel. The connecting sleeve is embedded inside the first concrete wall panel on the side away from the connecting block. A top block is integrally fixed on the side of the connecting block away from the first concrete wall panel. Two installation cavities are opened inside the connecting sleeve. An inclined plate is rotatably connected inside the installation cavity. Locking blocks are fixedly connected to the opposite sides of the two inclined plates. A slot adapted to the locking block is opened on the side wall of the top block. A torsion spring is arranged on the side of the inclined plate away from the locking block.

[0007] By adopting the above technical solutions, this application can form a thermal insulation sandwich structure, effectively improving the thermal insulation performance of the wall, reducing energy consumption, and the grid-like layout and variable density design of the reinforcing ribs significantly enhance the seismic resistance of the wall, reducing the damage risk during an earthquake. Moreover, the provision of the connecting block and the connecting sleeve facilitates the quick connection of adjacent walls and improves the construction efficiency.

[0008] Further, a groove is provided on the inner wall of the connecting sleeve, and a movable groove is provided inside the connecting sleeve between the groove and the installation cavity. A push rod is slidably connected inside the movable groove.

[0009] The beneficial effect of adopting the above further solution is that by providing the groove, when the connecting block is inserted into the connecting sleeve, the top block will be inserted into the groove.

[0010] Further, both ends of the push rod are in a bevel structure, and a limiting convex block is fixedly connected to the side wall of the push rod.

[0011] The beneficial effect of adopting the above further solution is that by setting both ends of the push rod to be in a bevel structure, when the top block is inserted into the groove, it will push the push rod to move to the side away from the top block.

[0012] Further, the locking block is in a trapezoidal structure, and both ends of the push rod are respectively located inside the installation cavity and the groove.

[0013] The beneficial effect of adopting the above further solution is that when the push rod moves, it will push the inclined plate to rotate, so that the locking block is inserted into the slot, and the connecting block can be limited.

[0014] Further, the connecting block is adapted to the inner wall of the connecting sleeve, and the end of the top block away from the connecting block is in a trapezoidal structure.

[0015] The beneficial effect of adopting the above further solution is that by providing the connecting block and the connecting sleeve, the connecting blocks on adjacent walls can be inserted into the connecting sleeve to quickly connect and install adjacent precast walls.

[0016] Further, reinforcing ribs are provided inside both the first concrete wall panel and the second concrete wall panel, and the reinforcing ribs are grid-like reinforcing ribs.

[0017] The beneficial effect of adopting the above further solution is that the grid-like layout and variable density design of the reinforcing ribs significantly enhance the seismic resistance of the wall, reducing the damage risk during an earthquake.

[0018] Further, reflective films are provided on both sides of the thermal insulation layer, and the first concrete wall panel, the thermal insulation layer, and the second concrete wall panel form a thermal insulation sandwich structure.

[0019] The beneficial effects of adopting the above further solution are as follows: By arranging reflective films on both sides of the thermal insulation layer, the heat transfer loss through the concrete layer can be reduced, thereby further improving the thermal insulation effect.

[0020] Furthermore, thin thermal insulation coatings are provided on the sides of the first concrete wall panel and the second concrete wall panel away from the thermal insulation layer.

[0021] The beneficial effects of adopting the above further solution are as follows: By arranging thin thermal insulation coatings on the outer walls of the first concrete wall panel and the second concrete wall panel, which are composed of nano-ceramic particles and binders, the thermal insulation effect of the wall can be further improved, and it has a certain waterproof function.

[0022] For this earthquake-resistant and thermally insulated precast concrete wall, by arranging the second concrete wall panel between the first concrete wall panel and the thermal insulation layer and the thin thermal insulation coating on the outer wall of the first concrete wall panel, a thermal insulation sandwich structure is formed, effectively improving the thermal insulation performance of the wall, reducing energy consumption. Moreover, the grid-like layout and variable density design of the reinforcing ribs significantly enhance the earthquake resistance of the wall, reducing the risk of damage during an earthquake. In addition, the arrangement of the connecting blocks and the connecting sleeves facilitates the quick connection of adjacent walls, improving the construction efficiency.

[0028] Please refer to Figures 1-3 , in a precast concrete wall with earthquake resistance and thermal insulation in this embodiment, it includes a first concrete wall panel 1, a second concrete wall panel 2, and a thermal insulation layer 3 arranged between the first concrete wall panel 1 and the second concrete wall panel 2. A plurality of connecting members are provided on the side wall of the first concrete wall panel 1.

[0029] The connecting piece includes a connecting block 4 and a connecting sleeve 6. The connecting block 4 is arranged on the side wall of the first concrete wall panel 1. The connecting sleeve 6 is embedded inside the first concrete wall panel 1 on the side away from the connecting block 4. One side of the connecting block 4 away from the first concrete wall panel 1 is integrally fixed with a top block 41. The inside of the connecting sleeve 6 is provided with two installation cavities 7. The inside of the installation cavity 7 is rotatably connected with an inclined plate 8. One side of the two inclined plates 8 facing each other is fixedly connected with a locking block 9. The side wall of the top block 41 is provided with a slot 11 adapted to the locking block 9. A torsion spring 10 is arranged on the side of the inclined plate 8 away from the locking block 9. The connecting block 4 is adapted to the inner wall of the connecting sleeve 6. One end of the top block 41 away from the connecting block 4 is of a trapezoidal structure.

[0030] It should be noted that by arranging the second concrete wall panel 2 between the first concrete wall panel 1 and the thermal insulation layer 3 and the thin thermal insulation coating arranged on the outer wall of the first concrete wall panel 1, a thermal insulation sandwich structure is formed, effectively improving the thermal insulation performance of the wall and reducing energy consumption. The grid-like layout and variable density design of the reinforcing ribs 5 significantly enhance the seismic resistance of the wall and reduce the damage risk during an earthquake. The arrangement of the connecting block 4 and the connecting sleeve 6 facilitates the quick connection of adjacent walls and improves the construction efficiency.

[0031] It can be understood that when connecting and installing adjacent precast concrete walls, when the two ends of the walls are translated and fitted together, the connecting block 4 will be inserted into the inside of the connecting sleeve 6, and the top block 41 will be inserted into the inside of the groove 12, thereby pushing the two sides of the push rod 13 to move, pushing the inclined plate 8 to tilt so that the locking block 9 is clamped into the inside of the slot 11, thereby achieving the locking effect. Due to the limitation of the locking block 9, the connecting block 4 will not move out of the connecting sleeve 6, thus ensuring the stability of the connection between adjacent precast walls.

[0032] Please refer to Figure 3 In this embodiment, a groove 12 is provided on the inner wall of the connecting sleeve 6. An activity groove 14 is provided inside the connecting sleeve 6 between the groove 12 and the installation cavity 7. A push rod 13 is slidably connected inside the activity groove 14. Both ends of the push rod 13 are of a bevel structure. A limiting convex block is fixedly connected to the side wall of the push rod 13. The locking block 9 is of a trapezoidal structure. Both ends of the push rod 13 are respectively located inside the installation cavity 7 and the groove 12.

[0033] It should be noted that the arrangement of the limiting convex block has a limiting effect on the push rod 13 to prevent the push rod 13 from completely falling into the inside of the groove 12. When the push rod 13 does not contact the inclined plate 8, the torsion spring 10 will make the locking block 9 located inside the installation cavity 7.

[0034] It is worth mentioning that the setting of the torsion spring 10 makes one end of the inclined plate 8 close to the push rod 13 at a lower position in the initial state, while the end provided with the locking block 9 is at a higher position, which will make the locking block 9 located inside the installation cavity 7, thus not hindering the insertion of the connecting block 4.

[0035] Among them, by setting the groove 12, when the connecting block 4 is inserted into the inside of the connecting sleeve 6, the top block 41 will be inserted into the inside of the groove 12.

[0036] By setting the two ends of the push rod 13 as inclined surface structures, when the top block 41 is inserted into the inside of the groove 12, the push rod 13 will be pushed to move to the side away from the top block 41.

[0037] It can be understood that when the push rod 13 moves, it will push the inclined plate 8 to rotate, so that the locking block 9 is inserted into the inside of the slot 11, and then the connecting block 4 can be limited, preventing the connecting block 4 from moving out of the connecting sleeve 6.

[0038] Among them, by setting the connecting block 4 and the connecting sleeve 6, inserting the connecting block 4 on the adjacent wall into the inside of the connecting sleeve 6 can quickly connect and install the adjacent precast walls.

[0039] Please refer to Figure 1 , reinforcing ribs 5 are arranged inside both the first concrete wall panel 1 and the second concrete wall panel 2, and the reinforcing ribs 5 are grid-shaped reinforcing ribs.

[0040] By adopting the above technical solution, the seismic capacity of the wall is significantly improved through the grid layout and variable density design of the reinforcing ribs 5, reducing the damage risk during an earthquake.

[0041] It should be noted that reflective films are arranged on both sides of the thermal insulation layer 3. The first concrete wall panel 1, the thermal insulation layer 3 and the second concrete wall panel 2 form a thermal insulation sandwich structure. By arranging reflective films on both sides of the thermal insulation layer 3, the heat transfer loss through the concrete layer can be reduced, thereby further improving the thermal insulation effect.

[0042] It is worth mentioning that the insulation layer 3 can be replaced by other high-efficiency insulation materials, such as aerogels, nanoporous insulation materials, etc., and the seismic reinforcement ribs can be replaced by high-performance fiber composite ribs. High-performance fiber composite ribs (FRP ribs) are a new type of building material that is composited by a specific process using high-performance fiber materials (such as carbon fiber, glass fiber, aramid fiber, etc.) and resin matrices (such as epoxy resin, vinyl resin, etc.). The density of FRP ribs is much smaller than that of steel bars, usually only about a quarter of that of steel bars, which significantly reduces the deadweight of the structure, helps to reduce the load on the supporting structure and reduce transportation and installation costs. FRP ribs have excellent tensile strength, which is two to three times that of steel bars of the same specification. This means that when subjected to tension, FRP ribs can provide higher strength and increase the safety of the structure. Therefore, high-performance fiber composite ribs are provided to reduce the weight of the wall while maintaining seismic performance.

[0043] The thermal insulation effect of nanoporous insulation materials is based on their nano-scale microporous structure, which can greatly limit the movement of gas molecules and heat transfer, and maintain extremely low thermal conductivity even at high temperatures. Due to its special nano-microporous structure, this material has very low thermal conductivity, which is much better than traditional thermal insulation materials.

[0044] Wherein, a thin thermal insulation coating is provided on one side of the first concrete wall panel 1 and the second concrete wall panel 2 away from the thermal insulation layer 3 .

[0045] A thin thermal insulation coating is arranged on the outer wall of the first concrete wall panel 1 and the second concrete wall panel 2. The coating is composed of nano-ceramic particles and a binder. The thin thermal insulation coating will not increase the thickness of the wall, but can further improve the thermal insulation effect of the wall and has a certain waterproof function.

[0046] The working principle of the above embodiment is as follows: an insulating sandwich structure is formed by the first concrete wall panel 1, the second concrete wall panel 2 and the insulation layer 3, which effectively improves the insulation performance of the wall and reduces energy consumption, while the grid layout and variable density design of the reinforcing ribs 5 significantly improve the seismic resistance of the wall and reduce the risk of damage during an earthquake. When connecting and installing adjacent prefabricated concrete walls, the two ends of the wall are translated and embedded together, and the connecting block 4 is inserted into the interior of the connecting sleeve 6, and the top block 41 is inserted into the interior of the groove 12, thereby pushing the push rods 13 on both sides to move, which will push the inclined plate 8 to tilt and make the locking block 9 snap into the interior of the slot 11, thereby achieving a locking effect, thereby facilitating quick connection and improving construction efficiency.
