Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an assembled concrete wall panel steel structure connection device. Background Art

[0002] Prefabricated concrete wall panel steel refers to a modular building component formed by combining concrete wall panels with steel structure frames through factory prefabrication. This component can be quickly assembled on site, which can greatly shorten the construction period and improve construction efficiency.

[0003] Prefabricated concrete wall panel steel is prefabricated in the factory, and only simple assembly and connection are required at the construction site, which greatly reduces the on-site construction time and improves construction efficiency. Since the prefabricated components are standardized in the factory, quality control is more stringent, which can effectively reduce quality problems and safety hazards in on-site construction. Prefabricated buildings reduce material waste and environmental pollution in on-site construction. At the same time, the steel structure itself is recyclable and reusable, which is in line with the concept of sustainable development.

[0004] For example, an assembled wall panel connection device with publication number CN118601179A relates to the technical field of assembled wall panel installation. The prior art includes a transparent wall panel and a hanging ring, wherein stabilizing components are provided on the left and right sides of the wall panel, and reinforcing components are provided on the upper and lower sides of the wall panel; the stabilizing component includes a plurality of reinforcing rings, and filling grooves are fixedly opened at both ends of the wall panel, and a plurality of reinforcing rings are evenly fixedly assembled inside the filling grooves, and the ends of a plurality of reinforcing rings extend to the outside of the filling grooves, and reinforcing ribs are installed on the inner sides of a plurality of reinforcing rings; the reinforcing component includes a double-headed threaded rod, a threaded hole is opened at the upper end of the wall panel, one end of the double-headed threaded rod is threadedly rotated and assembled inside the threaded hole, an assembly port is opened on the lower side of the wall panel, and a straight slot connected to the assembly port is opened at the lower end of the wall panel, and the straight slot is slidably matched with the double-headed threaded rod.

[0005] However, the above prior art still has some defects when it comes to wall panel installation and connection:

[0006] When the wall panels in the above-mentioned prior art are installed, the wall panels are heavy and inconvenient to carry. It is difficult to ensure verticality during installation, which causes the wall panels to deviate during installation.

[0007] During the connection process of two wall panels, the verticality of the double-headed threaded rods preset on the foundation cannot be guaranteed. If the double-headed threaded rods themselves are tilted, it will directly affect the verticality of the wall panels. Once the double-headed threaded rods themselves are tilted, it will directly cause the wall panels to shift during installation. Even if the adjustable wall panel diagonal support rods are used for fine-tuning later, it is difficult to completely correct this initial deviation.

[0008] At the same time, when using nuts to fix the lower side of the wall panel to the double-ended threaded rod, uneven tightening force may cause a small but significant displacement of the wall panel, affecting the verticality.

[0009] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for the installation and connection of wall panels. Summary of the invention

[0010] In order to solve the above technical problems, the present application provides a prefabricated concrete wall panel steel structure connection device, which adopts the following technical solutions:

[0011] An assembled concrete wall panel steel structure connection device comprises a prefabricated wall and a bottom plate, wherein the prefabricated wall is provided with a plurality of rows of positioning holes in a height direction, and one side of the prefabricated wall is provided with a plurality of pin holes distributed in a matrix, and the pin holes penetrate into a plurality of positioning holes in the same row;

[0051] The following combination Figures 1 to 19 This application is described in further detail.

[0052] An embodiment of the present application discloses an assembled concrete wall panel steel structure connection device, which fixes two adjacent walls at the same time and then calibrates the two adjacent walls so that the two adjacent walls maintain the same verticality. Thereafter, the gap between the two walls is enclosed and connected by pouring with reinforced cement to ensure the verticality of the prefabricated wall.

[0053] Embodiment 1:

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, an assembled concrete wall panel steel structure connection device includes a prefabricated wall 1 and a base plate 2. The prefabricated wall 1 is provided with multiple rows of positioning holes 11 along the height direction (the figure shows a common two-row structure), and one side of the prefabricated wall 1 is provided with a plurality of pin holes 12 distributed in a matrix. The pin holes 12 penetrate into multiple positioning holes 11 in the same column, that is, the pin holes 12 penetrate the positioning holes 11 in the same column in sequence from one side of the prefabricated wall 1, but do not penetrate the prefabricated wall 1, and multiple pin holes 12 are provided at different horizontal heights.

[0055] The prefabricated wall 1 is prefabricated in a factory and is simply assembled and connected at the construction site. During construction, a section of steel bars is reserved on the building foundation. When installing the prefabricated wall 1, the reserved steel bar section is first corrected to ensure the horizontality and verticality of the steel bar section, providing a stable benchmark for the installation of the prefabricated wall 1 and ensuring that the prefabricated wall 1 can remain vertical after installation.

[0056] When installing the prefabricated wall 1, first, the walking wheel 21 arranged on the base plate 2 will drive the base plate 2 to move with the positioning plate 3 hinged on one side thereof, so that the positioning plate 3 slides away from the side of the base plate 2 and the symmetrically arranged lifting plate 4 approaches the prefabricated wall 1. At this time, the angle adjuster 6 arranged between the base plate 2 and the positioning plate 3 will ensure that the angle of the positioning plate 3 is consistent with the angle of the prefabricated wall 1.

[0057] The pin holes 12 set on one side of the lifting plate 4 correspond to the pin tube 5 one by one and are aligned with the pin holes 12, so that the pin tube 5 is pinned into the pin holes 12 to limit the prefabricated wall 1. The motor drives the screw rod to rotate, and the nut connects the lifting plate 4 to move the lifting plate 4 on the positioning plate 3 to lift the prefabricated wall 1. Then the angle adjuster 6 will make the positioning plate 3 drive the prefabricated wall 1 to tilt toward the side of the bottom plate 2, and then the walking wheel 21 will drive its bottom plate 2 to drive the prefabricated wall 1 to move to the installation position, and then the angle adjuster 6 will calibrate the prefabricated wall 1 so that the prefabricated wall 1 is perpendicular to the ground, and the positioning hole 11 is aligned with the steel bar segment reserved on the foundation.

[0058] The lifting plate 4 descends to make the prefabricated wall 1 contact the ground, and the steel bar segment is inserted into the positioning hole 11. The angle adjuster 6 calibrates the prefabricated wall 1 again, thereby completing the mobile installation of the prefabricated wall 1. The prefabricated wall 1 is installed in place in turn by moving the base plate 2, completing the assembly of the entire wall.

[0059] A gap is reserved between two adjacent prefabricated walls 1 on the foundation. During the connection process of the two prefabricated walls 1, the walking wheel 21 drives the bottom plate 2 to drive the positioning plate 3 to move between the two prefabricated walls 1, so that the operating port 31 opened between the positioning plates 3 is aligned with the gap, and the pin tubes 5 on the two lifting plates 4 are respectively aligned with the half of the pin holes 12 on the two prefabricated walls 1, so that the pin tube 5 on a single lifting plate 4 is pinned into the half of the pin hole 12 on the corresponding prefabricated wall 1. Then the angle adjuster 6 will calibrate the two adjacent prefabricated walls 1 so that the two adjacent prefabricated walls 1 maintain the same verticality. Then, the gap between the two prefabricated walls 1 is enclosed through the operating port 31, and reinforced cement is used for pouring and connection.

[0060] Reference Figure 4 , Figure 5 and Figure 6As shown, specifically, the angle adjuster 6 includes an arc-shaped guide seat 61 symmetrically arranged on the base plate 2, an arc-shaped rack 62 connected to the positioning plate 3 is slidably arranged inside the arc-shaped guide seat 61, and a support 63 connected to the arc-shaped guide seat 61 is symmetrically arranged on the base plate 2, and the arc-shaped guide seat 61 is further supported by the support 63 to ensure the stability of the arc-shaped guide seat 61.

[0061] During calibration, the existing servo motor is used to drive the driving shaft 64 that rotates and passes through the two supports 63 to rotate. The rotating driving shaft 64 will drive the driving gear 641 set thereon to rotate together. The driving gear 641 will drive the arc-shaped rack 62 to move telescopically in the arc-shaped guide seat 61 through engagement with the arc-shaped rack 62. The arc-shaped rack 62 will drive the positioning plate 3 to rotate at the hinge point on the base plate 2, thereby changing the angle of the positioning plate 3. The lifting plate 4 is driven by the positioning plate 3 to calibrate the prefabricated wall 1. By synchronously controlling the angles of the two prefabricated walls 1, it can be ensured that the two prefabricated walls 1 maintain the same verticality, thereby improving the structural stability of the wall.

[0062] That is to say, by driving the driving shaft 64 to rotate forward and reverse, the contraction of the arc-shaped rack 62 in the arc-shaped guide seat 61 is controlled, and the angle of the positioning plate 3 is changed by the contraction of the arc-shaped rack 62 to calibrate the horizontal verticality of the prefabricated wall 1. That is, when the driving shaft 64 rotates forward, the driving gear 641 drives the arc-shaped rack 62 to extend out of the arc-shaped guide seat 61 through meshing, and the angle between the base plate 2 and the positioning plate 3 increases; conversely, when the driving shaft 64 rotates reversely, the driving gear 641 drives the arc-shaped rack 62 to contract in the arc-shaped guide seat 61 through meshing, and the angle between the base plate 2 and the positioning plate 3 decreases.

[0063] When the arc-shaped rack 62 contracts into the arc-shaped guide seat 61, the return spring 65 provided in the arc-shaped rack 62 and the arc-shaped guide seat 61 will be compressed. Conversely, when the arc-shaped rack 62 extends out of the arc-shaped guide seat 61, the return spring 65 will be released, ensuring stable engagement between the driving gear 641 and the arc-shaped rack 62, thereby achieving precise angle adjustment and reliable mechanical transmission.

[0064] At the same time, the return spring 65 can provide a certain rebound force, enhance the positioning accuracy of the positioning plate 3, ensure that the prefabricated wall 1 always maintains the correct angle and position during the installation process, and make the arc rack 62 and the positioning plate 3 automatically return to the initial position or preset position. In the process of adjusting the angle, the movement of the mechanical structure may produce impact and vibration. The return spring 65 can absorb these impacts and vibrations, reduce damage to other parts of the device, and extend the service life of the equipment.

[0065] Reference Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, a partition 66 is provided in the pin tube 5, and the partition 66 divides the pin tube 5 into an upper pipe 67 and a lower pipe 68. The gap between the two prefabricated walls 1 is then enclosed through the operation port 31. While reinforced cement is used for pouring and connection, cement is injected into the cavity 69 of the lifting plate 4 through an existing grouting pump. Since one end of the upper pipe 67 and the lower pipe 68 are both connected to the cavity 69, and the outlet of the upper pipe 67 is close to the positioning holes 11 of the outer row, which are the positioning holes 11 far away from the side of the pin tube 5, cement will enter the positioning holes 11 of the outer row through the upper pipe 67, and the outlet of the lower pipe 68 is close to the positioning holes 11 of the inner row, which are the positioning holes 11 close to the side of the pin tube 5, cement will enter the positioning holes 11 of the inner row through the lower pipe 68.

[0066] The cement flows in the positioning hole 11, wrapping the steel bar segment at the bottom to form a strong bond, forming a stable structure with the prefabricated wall 1, thereby enhancing the connection strength between the prefabricated wall 1 and the foundation, and improving the stability and earthquake resistance of the entire wall.

[0067] Reference Fig.11 , Fig.12 and Fig.13 As shown, during the installation of the prefabricated wall 1 and during the process of connecting two prefabricated walls 1, when the pin tube 5 enters the pin hole 12, the limiter 7 provided on the pin tube 5 will limit the prefabricated wall 1 to prevent the prefabricated wall 1 from shifting during the installation and connection process, thereby enhancing the overall stability of the wall and reducing rework and repair work caused by installation errors.

[0068] Specifically, the limiting member 7 includes a guiding inclined surface 71 disposed at one end of the pin tube 5 , a limiting block 72 is slidably disposed on the guiding inclined surface 71 , a guiding groove 73 is provided on the guiding inclined surface 71 , and a sliding block 74 connected to the limiting block 72 is slidably disposed in the guiding groove 73 .

[0069] A limit spring 75 located on one side of the slider 74 is pressed into the guide groove 73. The limit spring 75 will move the limit block 72 along the guide slope 71 to one side of the lifting plate 4 through the slider 74. At this time, the limit block 72 protrudes outward from the pin tube 5 and presses against the positioning hole 11, locking the pin tube 5 in the pin hole 12, ensuring that the prefabricated wall 1 will not deviate during the installation and connection process.

[0070] A guiding slope 76 is provided on the limit block 72, and an electric push rod 77 corresponding to the guiding slope 76 is embedded in the pin tube 5. When the pin tube 5 is to enter or exit the pin hole 12, the telescopic end of the electric push rod 77 is retracted and extended, and the inclined surface 78 provided at the telescopic end of the electric push rod 77 pushes the guiding slope 76 by corresponding to the guiding slope 76, so that the limit block 72 shrinks into the pin tube 5, and the limit block 72 drives the slider 74 to move in the guide groove 73 and compress the limit spring 75, so that the limit block 72 is unlocked, so that the pin tube 5 can smoothly exit or enter the pin hole 12.

[0071] Reference Fig.14 As shown, in addition, during the calibration process of the prefabricated wall 1, the horizontal positioning instrument 8 arranged on the positioning plate 3 can provide high-precision horizontality and verticality measurement to ensure that the prefabricated wall 1 meets the design requirements during the installation process.

[0072] Specifically, the horizontal positioning instrument 8 includes a level ruler 81 arranged on the positioning plate 3, an infrared transmitter 82 located at the center of the level ruler 81 is arranged on the positioning plate 3 through a bracket, an infrared receiver 83 located on the other side of the level ruler 81 is arranged on the positioning plate 3 through a bracket, and a level ball 84 is movably arranged in the level ruler 81. The level ball 84 is used to indicate the horizontal state. When the positioning plate 3 is in a horizontal state, the level ball 84 is located at the center position of the level ruler 81.

[0073] When calibrating the prefabricated wall 1, the infrared transmitter 82 emits a laser, which passes through the transparent level 81 and level ball 84 and is received by the infrared receiver 83. At this time, the positioning plate 3 is vertical to the ground, and the liquid filled in the level 81 is opaque.

[0074] When the positioning plate 3 is tilted, the level ball 84 will lean to one side, and the middle position of the level ruler 81 will be filled with opaque liquid. The laser cannot pass through the opaque liquid and will not be received by the infrared receiver 83, thereby judging that the positioning plate 3 is not in a horizontal state. At this time, the drive shaft 64 will rotate to calibrate the positioning plate 3 until the laser passes through the transparent level ruler 81 and the level ball 84 and is received by the infrared receiver 83. At this time, the positioning plate 3 is vertical to the ground.

[0075] Embodiment 2:

[0076] Reference Fig.14 , Fig.15 and Fig.16As shown, on the basis of Example 1, a connecting ring 85 located between the infrared receiver 83 and the level ruler 81 is provided on the positioning plate 3 through a bracket, a plurality of evenly distributed light blocking plates 86 are provided on the connecting ring 85, and a light-transmitting hole 861 is provided between the plurality of light blocking plates 86; a guide groove 851 corresponding to the light blocking plates 86 is slidably provided on the connecting ring 85, a sliding rod 87 connected to the light blocking plates 86 is slidably provided in the guide groove 851, an adjusting ring 88 is rotatably provided on one side of the connecting ring 85, an arc-shaped guide groove 89 corresponding to the guide groove 851 is provided on the adjusting ring 88, and one end of the sliding rod 87 is located in the corresponding arc-shaped guide groove 89.

[0077] By rotating the adjustment ring 88, the arc-shaped guide groove 89 on the adjustment ring 88 will force the sliding rod 87 to move in the guide groove 851, and drive the multiple light-blocking plates 86 to move synchronously, thereby changing the size of the light-transmitting hole 861 to change the accuracy of the laser passing through the light-transmitting hole 861. That is, when the light-transmitting hole 861 is opened wider, the range of laser penetration is also larger, and the vertical accuracy is lower; when the light-transmitting hole 861 is closed less, the range of laser penetration is also smaller, and the vertical accuracy is higher.

[0078] Embodiment three:

[0079] Reference Fig.17 , Fig.18 and Fig.19 As shown, based on the first and second embodiments, connection grooves 13 corresponding to the number of rows of positioning holes 11 are opened on both sides of the prefabricated wall 1, one side of the connection groove 13 is connected to the corresponding positioning holes 11 on both sides, and a detachable connection pin 9 is arranged in the connection groove 13.

[0080] Based on the above description, it can be known that a gap is reserved between two adjacent prefabricated walls 1 on the foundation. Before calibrating the verticality of the prefabricated wall 1, the connecting pin 9 is placed into the connecting groove 13 from the upper end of the gap through the operating port 31, and several connecting pins 9 are inserted into the corresponding connecting grooves 13 of the two adjacent prefabricated walls 1. The height positions of the connecting pins 9 are all located between the adjacent pin tubes 5, and the two walls are connected by the connecting pins 9.

[0081] After the calibration of the prefabricated wall 1 is completed, the gap between the two prefabricated walls 1 is enclosed through the operating port 31, and reinforced cement is used for pouring connection. The connecting pin 9 is poured between the two prefabricated walls 1 to form a rigid connection, making the two walls an integral structure, thereby enhancing the overall stability and shear resistance of the wall and improving the seismic performance.

[0082] Specifically, the connecting pin 9 includes a threaded connecting rod 91, and connecting rods 92 threadedly connected to the threaded connecting rod 91 are rotatably arranged on both sides, and the connecting rod 92 corresponds to the connecting groove 13. A ball pin 93 corresponding to the positioning hole 11 is arranged at one end of the connecting rod 92. The ball pin 93 is constructed as a hollow structure, and a plurality of connecting holes 94 are opened on the ball pin 93.

[0083] When placing the connecting pin 9 into the connecting groove 13 from the upper end of the gap, align the ball pin 93 with the positioning hole 11, move the threaded connecting rod 91 and the connecting rod 92 from the upper end of the gap downward, move the ball pin 93 between the adjacent pin tubes 5, and then rotate the connecting rod 92. Through the threaded connection, the connecting rods 92 on both sides are opened outward or contracted inward, so that the ball pin 93 is stuck in the positioning hole 11, thereby completing the fixation.

[0084] After the calibration of the prefabricated wall 1 is completed, the gap between the two prefabricated walls 1 is enclosed through the operating port 31, and reinforced cement is used for pouring and connection. The cement can enter the hollow structure of the ball pin 93 through the connecting hole 94, forming a firm mechanical connection with the ball pin 93 and the prefabricated wall 1. At the same time, the filling of cement increases the pull-out resistance and bearing capacity of the connecting pin 9.

[0085] The implementation principle of the present invention is:

[0086] (1): When installing the prefabricated wall 1, first calibrate the reserved steel bar segment to ensure the horizontality and verticality of the steel bar segment, provide a stable reference for the installation of the prefabricated wall 1, and ensure that the prefabricated wall 1 can remain vertical after installation.

[0087] (2): When installing the prefabricated wall 1, the pin tube 5 is inserted into the pin hole 12, and the limit spring 75 will move the limit block 72 along the guide slope 71 to one side of the lifting plate 4 through the slider 74. At this time, the limit block 72 protrudes outward from the pin tube 5 and presses against the positioning hole 11, locking the pin tube 5 in the pin hole 12, ensuring that the prefabricated wall 1 will not shift during the installation and connection process. The lifting plate 4 moves on the positioning plate 3 through the existing driving technology to lift the prefabricated wall 1.

[0088] (3): The inclined surface 78 set at the telescopic end of the electric push rod 77 pushes the guiding inclined surface 76 by corresponding to the guiding inclined surface 76, so that the limit block 72 shrinks into the pin tube 5. The limit block 72 will drive the slider 74 to move in the guide groove 73 and compress the limit spring 75, so that the limit block 72 is unlocked, allowing the pin tube 5 to smoothly exit or enter the pin hole 12.

[0089] (4): The angle adjuster 6 will then cause the positioning plate 3 to drive the prefabricated wall 1 to tilt toward the side of the base plate 2, and then the walking wheel 21 will drive the base plate 2 to drive the prefabricated wall 1 to move to the installation position. Subsequently, the angle adjuster 6 will calibrate the prefabricated wall 1 so that the prefabricated wall 1 is perpendicular to the ground and the positioning hole 11 is aligned with the steel bar segment reserved on the foundation.

[0090] (5): The lifting plate 4 is lowered to make the prefabricated wall 1 contact the ground, and the steel bar segment is inserted into the positioning hole 11. The angle adjuster 6 calibrates the prefabricated wall 1 again, thereby completing the mobile installation of the prefabricated wall 1. The prefabricated wall 1 is installed in place in turn by moving the base plate 2, completing the assembly of the entire wall.

[0091] (6): Place the connecting pin 9 from the upper end of the gap into the connecting groove 13 through the operating port 31, and insert several connecting pins 9 into the corresponding connecting grooves 13 of two adjacent prefabricated walls 1. The height position of the connecting pins 9 is located between the adjacent pin tubes 5, and the two walls are connected through the connecting pins 9.

[0092] (7): A gap is reserved between two adjacent prefabricated walls 1 on the foundation. During the connection process of the two prefabricated walls 1, the walking wheel 21 drives the bottom plate 2 to drive the positioning plate 3 to move between the two prefabricated walls 1, so that the operating port 31 opened between the positioning plates 3 is aligned with the gap, and the pin tubes 5 on the two lifting plates 4 are respectively aligned with the half of the pin holes 12 on the two prefabricated walls 1, so that the pin tube 5 on a single lifting plate 4 is pinned into the corresponding half of the pin hole 12 on the prefabricated wall 1.

[0093] (8): By rotating the adjustment ring 88, the arc-shaped guide groove 89 on the adjustment ring 88 will force the sliding rod 87 to move in the guide groove 851, thereby driving the multiple light-blocking plates 86 to move synchronously, thereby changing the size of the light-transmitting hole 861 to change the accuracy of the laser passing through the light-transmitting hole 861. That is, when the light-transmitting hole 861 is opened wider, the range of laser penetration is also larger, and the vertical accuracy is lower; when the light-transmitting hole 861 is closed smaller, the range of laser penetration is also smaller, and the vertical accuracy is higher.

[0094] (9): When calibrating the prefabricated wall 1, the middle position of the level ruler 81 will be filled with opaque liquid. The laser cannot pass through the opaque liquid and will not be received by the infrared receiver 83, thereby judging that the positioning plate 3 is not in a horizontal state. At this time, the drive shaft 64 will rotate to calibrate the positioning plate 3 until the laser passes through the transparent level ruler 81 and the level ball 84 and is received by the infrared receiver 83. At this time, the positioning plate 3 is vertical to the ground.

[0095] (10): By calibrating the two adjacent prefabricated walls 1 to maintain the same verticality, the gap between the two prefabricated walls 1 is then enclosed through the operating port 31, and reinforced cement is used for pouring connection. The cement can enter the hollow structure of the ball pin 93 through the connecting hole 94, forming a strong mechanical connection with the ball pin 93 and the prefabricated wall 1. At the same time, the cement filling increases the pull-out resistance and bearing capacity of the connecting pin 9.

[0096] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
