Description

Technical Field

[0001] This application relates to the technical field of precast wall construction, and in particular to a method for hoisting and constructing precast walls. Background Technology

[0002] Precast walls refer to reinforced concrete components that are prefabricated according to design specifications. Precast walls are a part of prefabricated construction, which involves transferring a large amount of on-site work from traditional construction methods to factories. The prefabricated walls are then transported from the factory to the construction site for assembly and installation. During construction, the precast walls are typically hoisted to a designated area and secured.

[0003] The relevant technology regarding the hoisting method of precast walls includes: inspecting the quality of the precast wall before hoisting, then hooking hooks onto the precast wall, and then slowly hoisting the precast wall. When moving the precast wall to the floor, the installer manually adjusts the position of the precast wall while holding it. At the same time, a mirror is placed below the precast wall to determine whether the lower sleeve of the precast wall is aligned with the connecting steel bars on the floor. After alignment, the precast wall is placed on the floor. Finally, the precast wall is supported before proceeding with subsequent operations.

[0004] In the aforementioned technologies, aligning the precast wall and connecting steel bars requires workers to constantly adjust the position of the precast wall and simultaneously use mirrors to continuously observe the position of the precast wall and connecting steel bars. This process is cumbersome and affects construction efficiency. Summary of the Invention

[0005] To improve construction efficiency, this application provides a method for hoisting and installing precast walls.

[0006] The precast wall hoisting construction method provided in this application adopts the following technical solution:

[0007] A method for hoisting and installing precast walls includes the following steps:

[0008] S1: Mark the installation location of the precast wall on the floor, and mark the guide line with the vertical marking line on the floor. The distance between the guide line and the end of the marking line is the same as the distance from the hoisting bar on the precast wall to the edge of the precast wall.

[0009] S2: Install a support rod on the guide line, and install a top rod on the support rod to support the support rod, so that the support rod is tilted towards the direction of the marking line;

[0010] S3: Install a guide device at the lifting point of the reinforcing bar on the precast wall;

[0011] S4: Use steel wire ropes and hoisting bars to connect the steel wire ropes to the tower crane, and hoist the precast wall to the marked position;

[0012] S5: Gradually lower the precast wall, and at the same time, connect the end of the guide device and the support rod and continue to lower the precast wall until the precast wall is placed on the marking line;

[0013] S6: Use cement mortar to fill the gaps between the precast walls and the floors for caulking.

[0014] By adopting the above technical solution, the support rod is placed in the designated position, and then the position of the precast wall is adjusted to the designated position through the cooperation of the guide device and the support rod. At the same time, the phenomenon of displacement during the placement of the precast wall is reduced, so that the precast wall can be placed on the floor and cooperate with the connecting bars, thereby improving construction efficiency.

[0015] Optionally, the guiding device includes a clamping plate, a middle rod, and a guide frame. Two clamping plates are provided, and the two clamping plates are respectively provided on both sides of the precast wall. The middle rod is provided between the two clamping plates. The guide frame is provided on the side of the precast wall near the support rod and is set on the clamping plate. The clamping plate is provided with fixing bolts for fixing the clamping plate to the precast wall. The end of the support rod near the guide frame is provided with a clamping rod. The guide frame has openings on both the side near the support rod and the floor. The clamping rod is clamped in the guide frame through the opening. The support rod passes through the opening and is connected to the clamping rod.

[0016] By adopting the above technical solution, when hoisting the precast wall, the clamping rod enters the guide frame through the opening, and the support rod is connected to the clamping rod through the opening to continue moving the precast wall. The clamping rod restricts the position of the guide frame, reducing the phenomenon of the precast wall shifting, so as to place the precast wall in the designated position.

[0017] Optionally, the support rod is provided with a mounting base at one end near the floor, the mounting base is connected to the floor, a stabilizing rod is provided on the mounting base, the stabilizing rod is arranged horizontally toward the precast wall, and a top rod is provided on the stabilizing rod, the top rod is connected to the support rod away from the stabilizing rod to support the support rod.

[0018] By adopting the above technical solution, a top rod is set to support the support rod, so that the support rod can be stably kept in an inclined state and the position of the precast wall can be stably guided, thereby improving the stability of the precast wall during placement.

[0019] Optionally, a stabilizing frame is provided on the stabilizing rod along its length, and a slider is provided inside the stabilizing frame. The slider is slidably disposed along the length of the stabilizing rod. The support rod and the mounting base are rotatably connected. The top rod and the support rod are rotatably connected. The end of the top rod away from the support rod is rotatably connected to the slider. The end of the top rod near the support rod is inclined in a horizontal direction toward the mounting base. The stabilizing frame is provided with a control component for adjusting the position of the slider.

[0020] By adopting the above technical solution, a control component is set to adjust the position of the slider. After the precast wall is placed in the designated position, the position of the slider is adjusted to drive the top rod to rotate, which in turn drives the support rod to rotate, so that the clamping rod remains in contact with the inner wall of the guide frame, thereby improving the stability of the cooperation between the support rod and the precast wall.

[0021] Optionally, the control component includes a bolt head and a screw, the screw being rotatably disposed within the stabilizing frame, the screw passing through the slider and being threadedly connected to the slider, the end of the screw extending through the stabilizing frame to the outside of the stabilizing frame, and the bolt head being disposed outside the stabilizing frame and connected to the end of the screw.

[0022] By adopting the above technical solution, rotating the bolt head causes the screw to rotate, and the rotation of the screw causes the slider to move within the stabilizing frame, thereby adjusting the position of the top rod.

[0023] Optionally, two intermediate rods are provided, with the two intermediate rods respectively located on both sides of the lifting rib. An installation groove is provided on the side of the clamping plate near the intermediate rod. The intermediate rod is slidably arranged in the installation groove in the direction toward the lifting rib. A rack is provided at the end of the intermediate rod near the installation groove. The rack is arranged in the sliding direction of the intermediate rod. The racks on the two intermediate rods are spaced apart. A gear is rotatably arranged in the installation groove. The gear meshes with the racks on both intermediate rods simultaneously.

[0024] By adopting the above technical solution, the intermediate rods are placed on both sides of the lifting rib, and then the intermediate rods are moved until they abut against the lifting rib. At the same time, under the action of gears and racks, the two intermediate rods move simultaneously. After the intermediate rods abut against the lifting rib, the center position of the clamping plate corresponds to the lifting rib, and the clamping plate is then placed in the designated position, thereby improving installation efficiency.

[0025] Optionally, the mounting groove is provided with an elastic element for adjusting the position of the intermediate rod, and the elastic element is connected to the intermediate rod and the inner wall of the mounting groove respectively.

[0026] By adopting the above technical solution, the elastic element drives the intermediate rod to move in the direction of the lifting rib, so that the intermediate rod is in contact with the lifting rib, and at the same time, it is easy to quickly place the intermediate rod in the designated position.

[0027] Optionally, the stabilizer bar is rotatably mounted on the mounting base, and the stabilizer bar is provided with a support bolt, which passes through the stabilizer bar and abuts against the floor to support the stabilizer bar.

[0028] By adopting the above technical solution, the stabilizer bar is rotated to a position parallel to the floor level, and the position of the stabilizer bar is fixed by the support bolts, thereby improving the stability of the top bar and the support bar.

[0029] Optionally, the end of the stabilizer bar is spaced apart from the precast wall, and an auxiliary plate is provided at the end of the stabilizer bar near the precast wall. An auxiliary bolt is threaded onto the stabilizer bar, and the auxiliary bolt is connected to the auxiliary plate to drive the auxiliary plate to abut against the precast wall.

[0030] By adopting the above technical solution and setting up auxiliary panels to abut against the precast walls, the stability of the precast walls is further improved.

[0031] Optionally, the guide frame has a guide section on the side away from the precast wall, and the guide section bends away from the precast wall on the side closest to the floor.

[0032] By adopting the above technical solution, a guide is set up so that the clamp rod can be placed in the guide frame during the placement of the precast wall. At the same time, the position of the precast wall is gradually guided and adjusted during the placement process until the precast wall is adjusted to the designated position, thereby improving the adjustment accuracy.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] By using support rods and guide frames, precast walls are gradually placed on the floor at designated locations, reducing the need for repeated manual adjustments to the position of the precast walls and improving construction efficiency. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0045] This application discloses a method for hoisting and installing precast walls. The method includes the following steps:

[0046] S1: Mark the installation position of the precast wall 2 on floor 1, and mark the guide line with the vertical marking line on floor 1. The spacing between the guide line and the end of the marking line is the same as the spacing between the hoisting rod 21 on the precast wall 2 and the edge of the precast wall 2.

[0047] S2: Install support rod 3 on the guide line, and install top rod 33 on support rod 3 to support support rod 3, so that support rod 3 is tilted towards the direction of the marking line;

[0048] S3: Install guide device 4 at the hoisting reinforcement 21 on the precast wall 2;

[0049] S4: Connect the precast wall 2 to the marking line by connecting the steel wire rope and the hoisting rod 21, and connect the steel wire rope to the tower crane;

[0050] S5: Gradually lower the precast wall 2, and at the same time, after the ends of the guide device 4 and the support rod 3 are engaged, continue to lower the precast wall 2 until the precast wall 2 is placed on the marking line;

[0051] S6: Use cement mortar to fill the gap between precast wall 2 and floor 1 for caulking treatment.

[0052] Reference Figures 1 to 3Two hoisting ribs 21 are spaced apart on the precast wall 2. Two guide devices 4 and two hoisting ribs 21 are also correspondingly provided. The guide device 4 includes a clamping plate 41, a middle rod 42, and a guide frame 43. Two clamping plates 41 are provided, and the middle rod 42 is positioned between the clamping plates 41, perpendicular to the clamping plates 41. The guide frame 43 is positioned on one of the clamping plates 41, on the side of the clamping plate 41 facing away from the precast wall 2. The middle rod 42 abuts against the side of the precast wall 2 closest to the hoisting ribs 21. Fixing bolts 412 are provided on the clamping plates 41, threadedly connected to the clamping plates 41, and passing through the clamping plates 41 to abut against the precast wall 2. Before construction, the clamping plates 41 are placed on both sides of the precast wall 2, and then the fixing bolts 412 are rotated until their ends abut against the precast wall 2, fixing the clamping plates 41 to the sides of the precast wall 2.

[0053] Reference Figure 2 and Figure 3 The support rod 3 has a mounting base 31 at its end, which is fixed to the floor 1 by anchors. The mounting base 31 is positioned on the guide line and spaced apart from the precast wall 2. The end of the support rod 3 away from the mounting base 31 is inclined towards the precast wall 2 to support it. The guide frame 43 has openings 431 on both the side near the floor 1 and the side away from the clamping plate 41. A clamping rod 32 is located at the end of the support rod 3 near the guide frame 43, abutting against the inner wall of the guide frame 43. When hoisting the precast wall 2, the clamping rod 32 enters the guide frame 43 through the opening 431, while the support rod 3 passes through the opening 431 on the side of the guide frame 43. After the precast wall 2 is placed on the floor 1, the side of the clamping rod 32 abuts against the inner wall of the guide frame 43, supporting the precast wall 2. The mounting base 31 is set on the guide line. During installation, when the clamping rod 32 and the guide frame 43 cooperate, the sleeve below the precast wall 2 corresponds to the connecting bar on the floor 1, thereby improving the installation efficiency.

[0054] Reference Figure 3 and Figure 4 A guide section 432 is provided on the side of the guide frame 43 away from the precast wall 2. The guide section 432 is bent away from the precast wall 2 on the side closer to floor 1. That is, after the precast wall 2 is bent, the area of ​​the opening 431 of the guide frame 43 on the side closer to floor 1 is increased. So that when the precast wall 2 is placed, the clamping rod 32 is placed in the opening 431 through the guide section 432. At the same time, the clamping rod 32 and the side of the guide section 432 abut against each other. As the precast wall 2 moves continuously, the clamping rod 32 gradually moves within the guide frame 43, correcting the position of the precast wall 2 so as to fit the precast wall 2 with the connecting reinforcement.

[0055] Reference Figure 5 and Figure 6 A stabilizing rod 5 is installed on the mounting base 31, and the stabilizing rod 5 is positioned horizontally towards the precast wall 2. A top rod 33 is installed on the stabilizing rod 5, with one end connected to the stabilizing rod 5 and the other end rotatably connected to the end of the support rod 3 near the clamping rod 32. Before installation, the support rod 3 is supported by the top rod 33, keeping the support rod 3 in an inclined state so that the clamping rod 32 and the guide frame 43 can cooperate.

[0056] Reference Figure 5 and Figure 6 A support rod 3 and a mounting base 31 are rotatably connected. A stabilizing frame 51 is provided on the stabilizing rod 5, and the stabilizing frame 51 is set along the length of the stabilizing rod 5. A slider 52 is slidably set inside the stabilizing frame 51, and the slider 52 is rotatably connected to the support rod 3 at one end and to the slider 52 at the other end. The end of the top rod 33 away from the slider 52 is inclined horizontally toward the mounting base 31. A control component 6 for adjusting the position of the slider 52 is provided on the stabilizing frame 51. After the locking rod 32 moves into the guide frame 43, the slider 52 is moved toward the mounting base 31 by the control component 6. The slider 52 drives the top rod 33 to rotate, and the top rod 33 drives the support rod 3 to rotate in the direction away from the floor 1, causing the locking rod 32 to abut against the inner wall of the guide frame 43, thus providing stable support for the precast wall 2.

[0057] Reference Figure 5 and Figure 6 The control component 6 includes a bolt head 61 and a screw 62. The screw 62 is rotatably mounted within the stabilizing frame 51 and is positioned along the sliding direction of the slider 52. The screw 62 passes through the slider 52 and is threadedly connected to it. When the screw 62 rotates, it drives the slider 52 to slide within the stabilizing frame 51. The end of the screw 62 extends through the stabilizing frame 51 to the outside of the stabilizing rod 5. The bolt head 61 is located outside the stabilizing frame 51 and is welded to the end of the screw 62. By rotating the screw 62 through the bolt head 61, the position of the slider 52 is adjusted, which in turn drives the top rod 33 to rotate.

[0058] Reference Figure 5 and Figure 6 A stabilizer bar 5 is rotatably mounted on the mounting base 31. A support bolt 7 is installed on the stabilizer bar 5, passing through it and threadedly connected to it. The end of the support bolt 7 passes through the stabilizer bar 5 and abuts against the floor 1. During installation, rotating the support screw 62 rotates the stabilizer bar 5, simultaneously supporting it and keeping it parallel to the surface of the floor 1, thus improving the stability of the support for the top rod 33.

[0059] Reference Figure 5 and Figure 6 An auxiliary plate 8 is provided at the end of the stabilizer bar 5, spaced apart from the end of the stabilizer bar 5 and the precast wall 2. The auxiliary plate 8 is positioned between the stabilizer bar 5 and the precast wall 2. An auxiliary bolt 81 is threaded onto the stabilizer bar 5, with the auxiliary bolt 81 positioned towards the precast wall 2. After the clamping rod 32 and the inner wall of the guide frame 43 abut against each other, rotating the auxiliary bolt 81 moves the auxiliary plate 8 to abut against the side of the precast wall 2, further enhancing the stability of the precast wall 2.

[0060] Reference Figure 7 and Figure 8 To facilitate the installation of the clamping plate 41 at a designated position on the precast wall 2, two intermediate rods 42 are provided along the length of the side of the precast wall 2. An installation groove 411 is provided on the side of the clamping plate 41 near the intermediate rod 42. The end of the intermediate rod 42 extends into the installation groove 411 and slides within the installation groove 411 towards the other intermediate rod 42. A rack 9 is provided at the end of the intermediate rod 42 and slides within the installation groove 411 in the direction of the intermediate rod 42's slide. The racks 9 at the same end of the two intermediate rods 42 are spaced apart vertically. A gear 91 is rotatably mounted within the installation groove 411, meshing with the racks 9 on both intermediate rods 42 simultaneously. That is, when one intermediate rod 42 moves, the other intermediate rod 42 is moved via the gear 91. To ensure that the two intermediate rods 42 move the same distance, during installation, the two intermediate rods 42 are placed on both sides of the lifting rib 21, and then the intermediate rods 42 are slid until their sides abut against the sides of the lifting rib 21. At this point, the center of the clamping plate 41 corresponds to the lifting rib 21, and the clamping plate 41 is installed in the designated position. Both ends of the intermediate rod 42 are provided with racks 9, which simultaneously restrict the position of the intermediate rod 42, improving the stability of the intermediate rod 42 during movement.

[0061] Reference Figure 7 and Figure 8 An elastic element 92 is provided in the mounting groove 411. The elastic element 92 can be a spring. The spring is arranged along the length of the rack 9. One end of the spring is connected to the side of the intermediate rod 42, and the other end is connected to the mounting groove 411. The spring drives the intermediate rod 42 to slide in the direction toward another intermediate rod 42. After the intermediate rod 42 is placed outside the lifting rib 21, under the action of the spring, the intermediate rod 42 moves to a state of contact with the lifting rib 21, thereby improving the installation efficiency.

[0062] The implementation principle of this application is as follows: During construction, the support rod 3 is installed at the designated position, i.e., the position of the guide line. At the same time, when hoisting the precast wall 2, the clamping rod 32 and the guide frame 43 are coordinated. After the clamping rod 32 and the guide frame 43 are coordinated, the sleeve on the precast wall 2 and the connecting bar of the floor 1 are aligned in the vertical direction. The precast wall 2 is then placed. At the same time, under the action of the clamping rod 32 and the support rod 3, the phenomenon of displacement of the precast wall 2 is reduced. The coordination of the sleeve and the connecting bar reduces the phenomenon of repeated manual adjustment of the position of the precast wall 2, thereby improving construction efficiency.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
