Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a precast concrete shear wall sandwich insulation wall panel. Background Technology
[0002] During the installation of precast concrete shear wall sandwich insulation wall panels, the connection and fixing process between the wall panel and the pre-reserved vertical steel bars in the wall is quite complicated. Workers often need to first adjust the position of the wall panel so that the steel bars are aligned with the pre-reserved holes on the wall panel, and then fix it with temporary supports or binding. This is not only labor-intensive and time-consuming, but also has poor stability. In particular, the wall panel itself is heavy and may tilt or even fall over if it is hit by a slight external force. This not only affects the construction progress, but also easily injures on-site workers, posing a considerable safety hazard.
[0003] More importantly, most existing connection structures only focus on the final fixing strength, but ignore the limiting requirements during the installation process. For example, if the gap between the steel bar and the hole in the wall panel is too large, the wall panel is prone to shaking during adjustment, making it difficult to align in one go. Or, there is a lack of special quick-fixing components, requiring workers to repeatedly calibrate, which affects efficiency and makes it difficult to guarantee connection accuracy. With the widespread application of precast wall panels in building construction, these connection inconveniences and safety risks during installation are becoming increasingly prominent. There is a need for a structure that can quickly fix and limit the wall panel and the vertical steel bar to improve construction safety and efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a precast concrete shear wall sandwich insulation wall panel to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A precast concrete shear wall sandwich insulation wall panel includes a concrete wall panel, an insulation layer installed inside the concrete wall panel, two steel reinforcement frames fixedly connected to the outer wall of the concrete wall panel, the ends of the steel reinforcement frames being located inside the concrete wall panel, and two connecting mounting plates fixedly connected to the outer wall of the concrete wall panel.
[0007] The outer wall of the connecting mounting plate is fixedly equipped with multiple limiting mechanisms for abutting and fixing the concrete reinforcing bars, and the outer wall of the concrete wall panel is also fixedly equipped with a connecting mechanism for quick docking with the hydraulic arm.
[0008] As a further aspect of this solution, the limiting mechanism includes multiple connecting pipes, and the outer wall of the connecting mounting plate has multiple through holes, with each connecting pipe welded and fixed to the inner wall of an adjacent through hole.
[0009] As a further aspect of this solution, a sliding tube is fitted onto the outer wall of the connecting pipe, and multiple connecting columns are fixedly connected to the bottom of the sliding tube. A mating base is fixedly connected between the bottoms of all the connecting columns, and a return spring is fixedly connected between the upper end of the mating base and the connecting mounting plate.
[0010] As a further aspect of this solution, the upper end of the slide tube is fixedly connected to an abutment sleeve, the upper end of the connecting tube is fixedly connected to a connecting ring, and the upper end of the connecting ring is rotatably connected to multiple abutment clamps with reset functions.
[0011] As a further aspect of this solution, the connecting mechanism includes a connecting block, which is fixedly connected to the outer wall of the concrete wall panel. An elastic telescopic arm is fixedly connected to the outer wall of the connecting block. A rotating cylindrical block is rotatably connected to the output end of the elastic telescopic arm. A cooperating rotating arm with a reset function is rotatably connected to the end of the rotating cylindrical block away from the elastic telescopic arm.
[0012] As a further aspect of this solution, the outer wall of the connecting block is also fixedly connected to a mating sleeve. The outer wall of the mating sleeve has a connection opening, and the outer wall of the mating sleeve also has a first mating groove and a second mating groove, both of which are connected to the connection opening.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When this utility model is used, during the hoisting and docking of concrete wall panels, when the wall panel contacts the ground, the base will drive the connecting column and sliding tube to move upward, causing the abutment clamp to automatically gather and tightly abut against the outer wall of the steel bar, forming an instant fixed limit. No manual adjustment or temporary support is required. It can effectively prevent the wall panel from shaking or tilting the moment it hits the ground, thus avoiding safety accidents caused by the collapse of the wall and ensuring the safety of construction personnel. It can also save the tedious steps of repeatedly calibrating the position of the steel bar and the hole in the wall panel.
[0015] 2. By inserting the round opening at the end of the hydraulic arm into the mating sleeve, rotating the mating rotating arm and squeezing the elastic telescopic arm, it is made to pass through the second mating groove and enter the connection opening. Then, the restoring force of the elastic telescopic arm is used to make the mating rotating arm tightly abut against the inner wall of the first mating groove. The precise docking and limiting of the hydraulic arm and the wall panel can be completed in a short time. This not only solves the problems of inaccurate positioning and loose fixing when connecting traditional hydraulic equipment to the wall panel, but also ensures the stability after docking through the self-locking characteristics of the mechanical structure, preventing the hydraulic arm from slipping or displacing during operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figure 1 As shown in the embodiment of this utility model, a precast concrete shear wall sandwich insulation wall panel includes a concrete wall panel 1. An insulation layer is installed inside the concrete wall panel 1. The insulation layer is made of fiber-reinforced composite material, which is composed of alkali-resistant glass fiber and epoxy resin. Two steel frame frames 2 are fixedly connected to the outer wall of the concrete wall panel 1. The ends of the steel frame frames 2 are located inside the concrete wall panel 1. Two connecting mounting plates 4 are also fixedly connected to the outer wall of the concrete wall panel 1 by bolts. Each connecting mounting plate 4 is located directly below an adjacent steel frame frame 2. Multiple limiting mechanisms 101 are fixedly installed on the outer wall of the connecting mounting plates 4 to abut and fix the concrete steel bars to be connected and poured. A connecting mechanism 201 is also fixedly installed on the outer wall of the concrete wall panel 1. The connecting mechanism 201 can quickly connect with the hydraulic arm used for support.
[0023] Example 2: Please refer to Figure 2 - Figure 3As shown, the limiting mechanism 101 includes multiple connecting pipes 5. The outer wall of the connecting mounting plate 4 has multiple through holes 6. Each connecting pipe 5 is welded and fixed to the inner wall of an adjacent through hole 6. The outer wall of the connecting pipe 5 is fitted with a sliding pipe 7. Multiple connecting posts 8 are fixedly connected to the bottom of the sliding pipe 7. The multiple connecting posts 8 are circumferentially distributed at the bottom of the sliding pipe 7. The outer wall of each connecting post 8 slides through the inside of the connecting pipe 5. A mating base 10 is fixedly connected between the bottoms of all the connecting posts 8. An anti-slip rubber pad is fixedly connected to the bottom of the mating base 10 to effectively increase the friction between the mating base 10 and the ground. The mating base 10 is located directly below the connecting mounting plate 4. A return spring 9 is fixedly connected between the upper end of the mating base 10 and the connecting mounting plate 4. The return spring 9 is fitted on the outer wall of the adjacent connecting post 8.
[0024] The upper end of the sliding tube 7 is fixedly connected to the abutment sleeve 11 by bolts. The abutment sleeve 11 is "wider at the top and narrower at the bottom". The abutment sleeve 11 is fitted on the outer wall of the connecting tube 5. The upper end of the connecting tube 5 is fixedly connected to the connecting ring 12. The upper end of the connecting ring 12 is rotatably connected to multiple abutment clamps 13 with reset function through a rotating shaft. Each abutment clamp 13 is engaged with a reset torsion spring between itself and the connecting ring 12. The multiple abutment clamps 13 are circumferentially distributed on the upper end of the connecting ring 12. Multiple anti-slip strips are fixedly connected to the opposite ends of the multiple abutment clamps 13. When all the abutment clamps 13 converge in the opposite direction, they will abut against the corresponding outer wall of the steel bar. The anti-slip strips can effectively enhance the friction between the abutment clamps 13 and the outer wall of the steel bar.
[0025] Please see Figure 1 , Figure 4 As shown, the connecting mechanism 201 includes a connecting block 16, which is fixedly connected to the outer wall of the concrete wall panel 1 by bolts. An elastic telescopic arm 14 is fixedly connected to the outer wall of the connecting block 16. The output end of the elastic telescopic arm 14 is rotatably connected to a rotating cylindrical block 21 via a rotating shaft. The end of the rotating cylindrical block 21 away from the elastic telescopic arm 14 is rotatably connected to a cooperating rotating arm 15 with a reset function.
[0026] A reset torsion spring is engaged between the rotating arm 15 and the rotating cylindrical block 21. A mating sleeve 19 is also fixedly connected to the outer wall of the connecting block 16. The elastic telescopic arm 14 is located inside the mating sleeve 19. A connection opening 20 is provided on the outer wall of the mating sleeve 19. A first mating groove 17 and a second mating groove 18 are also provided on the outer wall of the mating sleeve 19. Both the first mating groove 17 and the second mating groove 18 are connected to the connection opening 20.
[0027] The working principle of this utility model is as follows:
[0028] When using this utility model, the concrete wall panel 1 is fixed by a crane or hoist. When the concrete wall panel 1 is suspended above the prefabricated house, the connecting steel bars of the prefabricated house are passed through the inside of the steel frame 2. Each steel bar also needs to be passed through the corresponding through-hole 6 and the inside of the connecting pipe 5. Note that at this time, the concrete wall panel 1 is not yet in contact with the ground of the prefabricated house. When the concrete wall panel 1 is in contact with the ground of the prefabricated house, the base 10 will first contact the ground of the prefabricated house. The base 10 will drive all the connecting columns 8 to move upward. The connecting columns 8 will drive the sliding pipe 7 to move upward. The sliding pipe 7 will contact the outer wall of all the contact clamps 13. When all the contact clamps 13 are gathered together, they will contact and limit the outer wall of the steel bar. At this time, the contact clamps 13 will fix and limit the steel bar, effectively preventing the concrete wall panel 1 from shaking. It has a limiting function for the concrete wall panel 1, making it easier to operate and install.
[0029] The round opening at the end of the hydraulic arm passes through the outer wall of the mating sleeve 19. At this time, the mating rotating arm 15 is rotated 90 degrees, and the elastic telescopic arm 14 is squeezed by the mating rotating arm 15, so that the mating rotating arm 15 passes through the second mating groove 18 and enters the connection opening 20. The mating rotating arm 15 and the rotating cylindrical block 21 are rotated. When the mating rotating arm 15 and the first mating groove 17 are on the same horizontal plane, the squeezing of the elastic telescopic arm 14 is released. At this time, the elastic telescopic arm 14 will drive the mating rotating arm 15 to abut against the inner wall of the first mating groove 17. At this time, the mating rotating arm 15 can abut and limit the round opening of the hydraulic arm, realizing rapid docking.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
