Description

Technical Field

[0001] This invention relates to the field of building construction, and more particularly to a prefabricated wall connection device. Background Technology

[0002] During the installation of precast walls, a crane is used to lift the precast wall to the required installation position. Then, the steel bars on the precast wall are bent manually. After the position of the precast wall is adjusted manually, the crane lowers the precast wall and places shims under it. Then, the sleeve under the precast wall is fitted onto the steel bars at the installation position. Cement grout is then poured into the precast wall. Once the cement grout has solidified, the installation of the precast wall is complete. However, since the installation environment of the precast wall is outdoors, it is unavoidable that wind will rise during the installation process. Since the precast wall is suspended by the crane, it will sway constantly due to the wind, making it difficult for manual installation.

[0003] Furthermore, the process requires manual bending of each steel bar on the precast wall, which consumes a lot of manpower. In addition, the steel bars at the installation location of the precast wall are often crooked, which is difficult for workers to detect before installation. When the precast wall is lowered, it cannot be adjusted manually, so the precast wall must be moved aside before the steel bars at the installation location can be adjusted. After that, the precast wall is moved back and then lowered for installation. The whole installation process is cumbersome. Summary of the Invention

Detailed Implementation

[0028] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] A prefabricated wall connection device, such as Figures 1-2 and Figures 6-7 As shown, it includes a first vehicle body 1 and a second vehicle body 2; the first vehicle body 1 is provided with six first fixing parts 1a; all the first fixing parts 1a are detachably connected to the second vehicle body 2;

[0031] It also includes a fixing frame 3, a rotating rod 4, a first rotating wheel 5, a binding strap 6, and a first motor 7; a fixing frame 3 is fixedly connected to both the first vehicle body 1 and the second vehicle body 2; a rotating rod 4 is rotatably connected to all fixing frames 3; six first rotating wheels 5 are fixedly connected to all rotating rods 4; a binding strap 6 is wrapped around all the first rotating wheels 5 on the first vehicle body 1, and the other end of the binding strap 6 is detachably connected to the first rotating wheel 5 on the second vehicle body 2, so as to fix the precast wall through the binding strap 6, so that the precast wall will not sway in the wind; a first motor 7 is bolted to all fixing frames 3, and the output shaft of all the first motors 7 is fixedly connected to the adjacent rotating rod 4.

[0032] It also includes a fixing unit, which is connected to the first vehicle body 1 to prevent the precast wall from swaying left and right. The fixing unit includes a gear 201, a lead screw 202, a third fixing plate 203, a rotating plate 204, a fixing rod 205, a rack 206, and a third push rod 207. All the first fixing parts 1a are rotatably connected to two gears 201 distributed front and rear. All gears 201 are provided with a connecting part 201a, and all gears 201 are rotatably connected to a lead screw 202 through the connecting part 201a. All lead screws 202 are connected to a... The third fixed plate 203; two adjacent third fixed plates 203 are connected to a rotating plate 204; a fixed rod 205 is connected to the left side of all rotating plates 204, and the precast wall is fixed by the fixed rod 205 to prevent the precast wall from swaying left and right during movement; six racks 206 are slidably connected to the first vehicle body 1 and the second vehicle body 2, and the racks 206 mesh with the adjacent gears 201; six third push rods 207 are bolted to the first vehicle body 1 and the second vehicle body 2, and the telescopic end of the third push rod 207 is fixedly connected to the adjacent rack 206.

[0033] The working steps of the above embodiment are as follows: First, the present invention is placed at the position where the prefabricated wall needs to be installed. Then, the binding strap 6 is fixed on the first rotating wheel 5 on the second vehicle body 2. Then, the first motor 7 on the second vehicle body 2 drives the first rotating wheel 5 to rotate forward while the first motor 7 on the first vehicle body 1 rotates in reverse, so that the first rotating wheel 5 on the second vehicle body 2 winds up a part of the binding strap 6. Then, the first motor 7 stops rotating. Then, the present invention is moved to the position where the prefabricated wall needs to be installed. Then, the prefabricated wall is hoisted above the present invention by an external crane. Then, the prefabricated wall is brought into contact with the binding strap 6 by the crane, so that the binding strap 6 supports the lower part of the prefabricated wall, so that the wind cannot blow the prefabricated wall. Therefore, the lower part of the prefabricated wall will not sway under the support of the binding strap 6, and the upper part of the prefabricated wall is still suspended by the crane, so that not all the weight of the prefabricated wall is applied to the binding strap 6.

[0034] Furthermore, the precast wall can be prevented from tilting significantly by using a crane. During the process of placing the precast wall on the binding strap 6, the precast wall will sway due to the wind, causing it to tilt when placed on the binding strap 6. Therefore, after the precast wall is placed on the binding strap 6, the first motor 7 drives the first wheel 5 on the first vehicle body 1 and the second vehicle body 2 to rotate in opposite directions, thereby moving the binding strap 6 and adjusting the position of the precast wall on the binding strap 6 so that the precast wall can be kept perpendicular to the floor slab.

[0035] Since the precast wall is placed on the binding strap 6, the precast wall and the binding strap 6 are in a swing-like state, which makes the precast wall prone to swaying in the left and right directions. Therefore, after the precast wall is placed on the binding strap 6, the third push rod 207 pushes the rack 206 to move, so the rack 206 drives the gear 201 to rotate, so the gear 201 drives the lead screw 202, the third fixing plate 203 and the rotating plate 204 and all the connected parts to move upward, so that the fixing rod 205 moves upward and inserts into the sleeve below the precast wall, thereby limiting the precast wall and preventing the precast wall from swaying in the left and right directions.

[0036] The precast wall is then transported manually to the installation location. During the movement, the reinforcing bars on the precast wall are adjusted to facilitate subsequent installation. The first motor 7 drives the binding strap 6 to rotate, lowering the precast wall downwards. Simultaneously, a crane lowers the precast wall downwards. The position of the precast wall is then manually adjusted so that the sleeve at the bottom of the precast wall can fit onto the reinforcing bars at the installation location. Jacks are then placed to the left and right of the bottom of the precast wall to support it. Next, the third push rod 207 pulls the rack 206, causing the lead screw 202 to move downwards, thus removing the fixing rod 205 from the lower sleeve of the precast wall. The second vehicle body 2 and the first fixing part 1a are then disassembled manually. The first vehicle body 1 is then pulled away from the second vehicle body 2. Simultaneously, the first motor 7 drives the binding strap 6 to rotate, lowering the precast wall downwards. Machine 7 drives the first rotating wheel 5 on the first vehicle body 1 to rotate and wind up the binding strap 6. When the binding strap 6 on the first rotating wheel 5 on the second vehicle body 2 has been fully pulled out, the connection position between the binding strap 6 and the first rotating wheel 5 on the second vehicle body 2 is exposed, making it convenient for manual disassembly. Then, the manual removes the binding strap 6 from the first rotating wheel 5 on the second vehicle body 2, thus completing the separation of the first vehicle body 1 and the second vehicle body 2. At this time, the manual uses a jack to completely lower the precast wall, and when there is a little distance left, a pad is placed under the precast wall. After the pad supports the precast wall, the jack is removed. Then, the manual adjusts the verticality of the precast wall and fixes it in place. Then, grout is poured into the precast wall to complete the connection of the precast wall. After the manual reconnects the first vehicle body 1, the second vehicle body 2, and the binding strap 6, the connection of the next precast wall can be carried out.

[0037] Example 2

[0038] Based on Example 1, such as Figures 3-5 As shown, it also includes a rebar adjustment unit, which is used to bend the rebar of the precast wall to facilitate the installation of the precast wall. The rebar adjustment unit consists of a first fixing plate 101, a first push rod 102, a second fixing plate 103, a first sliding plate 104, a second push rod 105, and rebar adjustment components. Two first fixing plates 101 are fixedly connected to the upper sides of the first vehicle body 1 and the second vehicle body 2. Three first push rods 102 are bolted to all the first fixing plates 101. The telescopic ends of all the first push rods 102 are fixedly connected to the second fixing plates 103. All the second fixing plates 103 on the same first fixing plate 101 are slidably connected to the first sliding plate 104. A second push rod 105 is bolted to all the second fixing plates 103, and the telescopic ends of all the second push rods 105 are fixedly connected to the adjacent first sliding plate 104. Six rebar adjustment components are connected to all the first sliding plates 104.

[0039] The rebar adjustment component includes a second sliding plate 106, a pressing block 107, a spring telescopic rod 108, a push plate 109, a first rope 1010, a gravity ball 1011, a second rotating wheel 1012, a second motor 1013, and a second rope 1014. The first sliding plate 104 is connected to the second sliding plate 106. The second sliding plate 106 is slidably connected to the pressing block 107. The second sliding plate 106 is fixedly connected to two symmetrically distributed spring telescopic rods 108, and the other end of each spring telescopic rod 108 is fixedly connected to the pressing block 107. The pressing block 107 is fixedly connected to the first rope 1010, and the other end of the first rope 1010 is fixedly connected to... A gravity ball 1011 is used to fix the steel bars on the precast wall through the gravity ball 1011 and the first rope 1010; a first sliding plate 104 is rotatably connected to two second rotating wheels 1012; a second motor 1013 is bolted to the first sliding plate 104, and the output shaft of the second motor 1013 is fixedly connected to the second rotating wheels 1012; all the second rotating wheels 1012 are wound with a second rope 1014, and the other end of the second rope 1014 passes through the second fixing part 104a and the second sliding plate 106 and is fixedly connected to the extrusion block 107. The steel bars on the precast wall are pulled downward by the second rope 1014, thereby causing the steel bars to bend downward.

[0040] The rebar adjustment component also includes a push plate 109; the extrusion block 107 is fixedly connected to the push plate 109; when the spring telescopic rod 108 pushes the extrusion block 107, it can drive the push plate 109 to move, thereby pushing the gravity ball 1011 to rotate rapidly upward through the push plate 109, which can better fix the rebar on the precast wall.

[0041] The extrusion block 107 is provided with a V-shaped groove and is inclined on the side opposite to the first sliding plate 104, so that when the second rope 1014 pulls the extrusion block 107, the gravity ball 1011 will not detach from the steel bar.

[0042] The extrusion block 107 is made of magnetic material, and the first sliding plate 104 and the second sliding plate 106 are slidably connected, so that the extrusion block 107 can attract the steel bars on the precast wall and move along the steel bars. When the second rope 1014 pulls the extrusion block 107, it can be pulled adaptively according to the inclination of the steel bars on the precast wall, so that all the steel bars on the precast wall are bent to the required degree.

[0043] The working steps of the above embodiment are as follows: After the precast wall is placed on the binding strap 6, the second fixing plate 103, the first sliding plate 104, the second push rod 105 and all their connected parts are pushed by the first push rod 102 to move towards the precast wall. Then, when the pressing block 107 contacts the steel bars on the precast wall, the second fixing plate 103 stops moving. Then, the pressing block 107 sucks up the steel bars on the precast wall. Then, the second push rod 105 pulls the first sliding plate 104 to move away from the precast wall. This causes the extrusion block 107 to move along the reinforcing bars on the precast wall. When the extrusion block 107 moves to the bend of the reinforcing bars in the precast wall, it stops moving. Since the extrusion block 107 moves along the reinforcing bars on the precast wall, when the extrusion block 107 is pulled down to bend the reinforcing bars, the reinforcing bars can be pulled to the required bending degree regardless of whether the reinforcing bars on the precast wall are tilted upward or downward. And when the gravity ball 1011 is pushed to fix the reinforcing bars, the reinforcing bars can be fixed regardless of whether they are tilted to the left or right.

[0044] Subsequently, the second motor 1013 drives the second rotating wheel 1012 to rotate, thereby causing the second rope 1014 to wind up. This pulls the extrusion block 107 away from the reinforcing bars on the precast wall, compressing the spring telescopic rod 108. When the extrusion block 107 contacts the first sliding plate 104, the second motor 1013 stops rotating. Then, the second motor 1013 reverses, causing the extrusion block 107 to stop compressing the spring telescopic rod 108. The spring telescopic rod 108 then pushes the extrusion block 107 back to its original position. The extrusion block 107 then drives the push plate 109 to move closer to the reinforcing bars on the precast wall, thus impacting the gravity ball 1011. This causes the gravity ball 1011 to swing closer to the reinforcing bars. After passing around the reinforcing bars on the precast wall, the gravity ball 1011 impacts the second sliding plate 106 and stops rotating. At this point, the gravity ball 1011 is located at the extrusion block 107. Between the pressing block 107 and the first sliding plate 104, the reinforcing bar can be moved by the gravity ball 1011 and the first rope 1010 when the pressing block 107 is pulled. Then, the second rope 1014 is wound up by the rotation of the second motor 1013. When the pressing block 107 moves to contact the first sliding plate 104, it continues to be pulled. At this time, since the spring telescopic rod 108 can no longer retract, the continued pulling will pull the second sliding plate 106 and the pressing block 107 downward. Since the gravity ball 1011 is restricted between the pressing block 107 and the first sliding plate 104, the gravity ball 1011 cannot separate from the reinforcing bar, thus pulling the reinforcing bar downward. When the second sliding plate 106 moves downward to the position of the second fixed part 104a, the pulling stops. At this time, the reinforcing bar has been bent downward, which facilitates the subsequent installation of the precast wall.

[0045] Example 3

[0046] Based on Example 2, such as Figures 6-7 As shown, the fixing rod 205 is a hollow cylinder, and the inner diameter of the fixing rod 205 is larger than that of the reinforcing bar, so that the fixing rod 205 can be used to detect whether the reinforcing bar at the installation position is skewed.

[0047] The rotating plate 204 is rotatably connected to the fixed rod 205, and two adjacent rotating plates 204 are rotatably connected to the fixed rod 205. The first vehicle body 1 is provided with another first fixing part 1a, which is located on the far left. The other first fixing part 1a is also connected to a gear 201 and a lead screw 202. The other two lead screws 202 are fixedly connected to another rotating plate 204. The other rotating plate 204 is rotatably connected to the rightmost fixed rod 205 on the right. The same rack 206 and third push rod 207 are provided on the left and right sides of the other first fixing part 1a. The third fixing plate 203 is rotatably connected to the rotating plate 204. Thus, by rotating the two adjacent racks 206 and moving the two adjacent rotating plates 204 up and down, the fixed rod 205 can tilt in the same direction as the skew of the steel bar at the installation position, so that the steel bar at the installation position can be corrected by the fixed rod 205.

[0048] The first vehicle body 1 and the second vehicle body 2 are each fixedly connected to two left and right distributed cleaning blocks 301. The cleaning blocks 301 sweep away cement blocks or stones on the moving path of the present invention, thereby preventing the cement blocks or stones from causing the first vehicle body 1 and the second vehicle body 2 to bump, and thus preventing the precast wall from shaking.

[0049] The above-described working steps are as follows: Since the reinforcing bars at the installation location of the precast wall may be misaligned, when lowering the precast wall, the third push rod 207 first pulls the rack 206, causing the lead screw 202 to move downwards. Then, the downward movement of the fixing rod 205 checks whether the reinforcing bars at the installation location are misaligned. If misalignment is found, the third push rod 207 pushes the rack 206 again, causing the fixing rod 205 to move upwards. When the distance between the fixing rod 205 and the reinforcing bars at the installation location is three to five centimeters, the fixing rod 205 stops moving upwards. Then, the third push rod 207 pulls the rack 206 again, causing the fixing rod 205 to move upwards. The device moves downwards again, and during this movement, the third push rod 207 repeatedly pushes the rack 206 to move left and right, causing the lead screw 202 to move up and down repeatedly. The two lead screws 202 on the same connecting part 201a rotate in opposite directions, and the two adjacent lead screws 202 on the left and right also rotate in opposite directions. This allows the fixing rod 205 to sway back and forth and left and right repeatedly during the downward movement, so that the fixing rod 205 can be fitted onto the skewed steel bar at the installation position. The repeated swaying of the fixing rod 205 corrects the skewed steel bar at the installation position, thereby allowing the sleeve below the precast wall to be fitted onto the steel bar at the installation position.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
