Description

Technical Field

[0001] This invention belongs to the field of intermediate retaining wall construction technology, specifically relating to an auxiliary frame for precast beam casting and a method for casting precast beams. Background Technology

[0002] During the construction of the intermediate retaining wall, in order to reduce the amount of high-altitude construction work and shorten the construction period, the connecting beams between the main beams were prefabricated. The prefabricated connecting beams were then hoisted between the connecting slots of the two main beams and formwork and pouring were carried out to fix the connecting beams on the main beams. However, in order to ensure the safety of the construction process, auxiliary frames need to be erected between the two main beams during the formwork and pouring of the connecting beams. However, the erected auxiliary frames are not easy to move. When auxiliary formwork and pouring are carried out for connecting beams at other positions between the two main beams, the auxiliary frames need to be hoisted and moved again, which is a cumbersome operation and reduces the construction efficiency of prefabricated beam pouring. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an auxiliary frame for precast beam casting and a method for casting precast beams, which solves the problem of low efficiency due to frequent hoisting of auxiliary frames during the casting of connecting beams in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An auxiliary frame for precast beam casting and installation includes an auxiliary frame body, a support assembly, a moving assembly, a lifting assembly, and a drive assembly. The auxiliary frame body includes a base plate and a guardrail, with first fixing plates at both ends of the guardrail. The support assembly is used to fix the auxiliary frame body to two adjacent main beams, located on the side of the connecting beam. The moving assembly drives the auxiliary frame body to reciprocate along the main beam. The lifting assembly controls the raising or lowering of the moving assembly relative to the support assembly. The drive assembly controls the raising and lowering of the lifting assembly, as well as the reciprocating movement of the moving assembly along the main beam.

[0006] Both the support component and the moving component are located at the lower end of the first fixed plate. The moving component can move up and down relative to the support component. The first fixed plate is provided with a lifting component to control the raising and lowering of the moving component. When the auxiliary frame body needs to move, the moving component is controlled to descend to the main beam and then move on the main beam. When the auxiliary frame body moves to the target position, the moving component is controlled to rise, the support component is subjected to force, and the auxiliary frame body is fixed on the main beam.

[0007] A first mounting box is provided on the guardrail, and a drive component is provided inside the first mounting box. The drive component is connected to the lifting component and is used to drive the lifting action of the lifting component.

[0008] A second mounting box is installed on the outside of the first mounting box, and a labor-saving component is installed inside the second mounting box to drive the operation of the drive component.

[0009] The drive assembly and the lifting assembly are connected by a pull rope, and the lifting assemblies on both sides move synchronously.

[0010] Limiting components are provided on both sides of the guardrail. The limiting components are used to press the two ends of the auxiliary frame body against the side wall of the main beam during construction.

[0011] The limiting component is also provided with a guide component for the limiting component drive adjustment.

[0012] A method for casting precast beams includes the following steps:

[0013] Step 1: Fix the main beam to the upper end of the support platform using a support frame. Set several connecting grooves at intervals on the main beam. After pouring, place both ends of the connecting beam in the connecting grooves.

[0014] Step 2: On the side of the connecting beam to be poured, an auxiliary frame for precast beam pouring and installation is erected between two adjacent main beams.

[0015] Step 3: Install the formwork for the connecting beams and pour the concrete.

[0016] Step 4: Activate the lifting assembly of the installation auxiliary frame, lower the moving assembly onto the main beam to bear the load, and move the installation auxiliary frame to the side of the next connecting beam to be poured;

[0017] Step 5: Repeat steps 3 and 4 until all connecting beams are poured.

[0018] Step 6: Remove the installation auxiliary frame to complete the construction.

[0019] After the precast beam casting and installation auxiliary frame is installed, adjust the limiting components of the auxiliary frame to be close to the side of the main beam. After the construction is completed, loosen the limiting components first, and then move the auxiliary frame.

[0020] After the auxiliary frame moves to the target position, the moving component is first raised to return to its initial state, so that the supporting component is subjected to force.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The precast beam casting and installation auxiliary frame, through the cooperation of support components, moving components, lifting components and drive components, facilitates the movement of the installation auxiliary frame body between the two main beams after hoisting, and adjusts the usage position of the installation auxiliary frame body.

[0023] 2. The precast beam casting and installation auxiliary frame has a simple structure and is easy to operate. During application, the auxiliary frame is firmly attached to the main beam by the limiting components, which further enhances safety.

[0024] 3. Using this auxiliary frame for precast beam construction makes it easier to assist in the pouring and formwork of connecting beams at other positions between two main beams after the auxiliary frame body is hoisted and placed. This eliminates the need to repeatedly lift and move the auxiliary frame body, thus improving the construction efficiency of precast beam pouring. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0038] An auxiliary frame for precast beam casting and installation includes an auxiliary frame body, a support assembly, a moving assembly, a lifting assembly, and a drive assembly. The auxiliary frame body includes a base plate and a guardrail, with first fixing plates at both ends of the guardrail. The support assembly is used to fix the auxiliary frame body to two adjacent main beams, located on the side of the connecting beam. The moving assembly drives the auxiliary frame body to reciprocate along the main beam. The lifting assembly controls the raising or lowering of the moving assembly relative to the support assembly. The drive assembly controls the raising and lowering of the lifting assembly, as well as the reciprocating movement of the moving assembly along the main beam.

[0039] Specific embodiments, such as Figures 1 to 11 As shown,

[0040] An auxiliary frame for casting and installing precast beams includes an installation auxiliary frame body 6 disposed on one side of a connecting beam 4. The installation auxiliary frame body 6 consists of a base plate 601 and a guardrail 602. The guardrail 602 is fixed to the upper end of the base plate 601. The connecting beam 4 is disposed between two main beams 2. The main beams 2 are provided with multiple connecting grooves 5 for connecting and placing the connecting beam 4. The main beams 2 are fixed to the upper end of a support platform 1 by a support frame 3. First fixing plates 7 are fixed on both sides of the guardrail 602. The two first fixing plates 7 are provided with support components that facilitate the erection and movement of the installation auxiliary frame body 6. The movable component, the guardrail 602 is provided with limiting components on both sides for supporting and limiting the installation auxiliary frame body 6 after it is erected. Through the cooperation of the support component, movable component, lifting component and drive component, the installation auxiliary frame body 6 can be moved between the two main beams 2 after being hoisted, and the position of the installation auxiliary frame body 6 can be adjusted. This makes it easier for the installation auxiliary frame body 6 to assist in the pouring and formwork of the connecting beams 4 at other positions between the two main beams 2 after it is hoisted, without the need to repeatedly lift and move the installation auxiliary frame body 6, thus improving the construction efficiency of precast beam pouring.

[0041] Specifically, the support assembly includes support rods 801 fixed at the four corners of the lower end of the first fixed plate 7, and a support plate 802 is fixed to the lower end of each support rod 801.

[0042] Specifically, the moving component includes a sliding plate 901 located below the first fixed plate 7, each support rod 801 slidably connected to the sliding plate 901, and four rotating wheels 902 fixed at the lower corners of the sliding plate 901. The first fixed plate 7 is provided with a lifting component for raising and lowering the sliding plate 901.

[0043] Specifically, the lifting assembly includes a first threaded tube 1002 rotatably connected to the first fixed plate 7, a first threaded rod 1001 threadedly engaged with the first threaded tube 1002, one end of the first threaded rod 1001 being fixed to the upper end of the sliding plate 901, a first mounting box 11 fixed on the guardrail 602, and a rotating assembly provided on the first mounting box 11 for synchronously rotating the first threaded tubes 1002 on both sides of the auxiliary frame body 6. Through the rotating assembly, the first threaded tubes 1002 on the two first fixed plates 7 are driven to rotate. During the rotation of the first threaded tube 1002, the sliding plate 901 is driven to rise and fall through the mutual meshing transmission between the first threaded tube 1002 and the first threaded rod 1001 and the guiding effect of each support rod 801 on the sliding plate 901.

[0044] Specifically, the rotating assembly includes two symmetrically arranged mounting shafts 1201 rotatably connected inside the first mounting box 11. First winding reels 1202 are fixed to the two mounting shafts 1201, and pull ropes 1203 are wound onto the two first winding reels 1202. Second winding reels 1204 are fixed to the upper ends of the two first threaded tubes 1002. The other ends of the two pull ropes 1203 pass through the first mounting box 11 and are respectively wound onto the two first threaded tubes 1002. The two mounting shafts 1201 are connected by a transmission assembly. The first mounting box 11 is provided with mounting shafts... The drive assembly driven by 1201 has a push assembly on the guardrail 602 for pushing the two pull ropes 1203. The drive assembly drives the two mounting shafts 1201 on the first mounting box 11 to rotate. During the rotation of the two mounting shafts 1201, the two first winding reels 1202 are driven to rotate. The rotation of the two first winding reels 1202 pulls and winds the pull ropes 1203. During the pulling and winding of the two pull ropes 1203, the pull ropes 1203 drive the first threaded tubes 1002 on the two first fixed plates 7 to rotate.

[0045] Specifically, the driving component includes a rotating shaft 1301 rotatably connected to the guardrail 602. A support wheel 1302 is fixed at the upper end of the rotating shaft 1301. The pull rope 1203 is abutted against the support wheel 1302. The support wheel 1302 supports the pull rope 1203, which facilitates the stable transmission of the pull rope 1203.

[0046] Specifically, the transmission assembly includes a first gear 1401 and a second gear 1402 respectively fixed on two mounting shafts 1201, with the first gear 1401 and the second gear 1402 meshing with each other. The drive assembly includes a connecting shaft 1501 rotatably connected to the first mounting box 11, with a worm gear 1502 fixed on the connecting shaft 1501. A worm wheel 1503 is fixed to one end of the mounting shaft 1201, with the worm gear 1502 and the worm wheel 1503 meshing with each other. A second mounting box 11 is fixed to the outside of the first mounting box 11. The second mounting box 16 is equipped with a force-saving component for driving the connecting shaft 1501. The force-saving component drives the connecting shaft 1501 to rotate. During the rotation of the connecting shaft 1501, the meshing transmission between the worm gear 1502 and the worm wheel 1503 drives the mounting shaft 1201 to rotate. During the rotation of the mounting shaft 1201, the meshing transmission between the first gear 1401 and the second gear 1402 drives the two mounting shafts 1201 on the first mounting box 11 to rotate.

[0047] Specifically, the labor-saving component includes a third gear 1701 disposed inside the second mounting box 16. One end of the connecting shaft 1501 is located inside the second mounting box 16 and fixed to the third gear 1701. A drive shaft 1702 is rotatably connected to the second mounting box 16. A fourth gear 1703 is fixed to one end of the drive shaft 1702. The third gear 1701 and the fourth gear 1703 are meshed with each other, and the number of teeth of the third gear 1701 is several times the number of teeth of the fourth gear 1703. A first handle 1704 is fixed to one end of the drive shaft 1702. Through the first handle 1704, the fourth gear 1703 at one end of the drive shaft 1702 is driven to rotate. During the rotation of the fourth gear 1703, the connecting shaft 1501 is driven to rotate through the meshing transmission between the fourth gear 1703 and the third gear 1701. During the entire driving process, because the number of teeth of the third gear 1701 is several times the number of teeth of the fourth gear 1703, the lever principle makes the driving process more labor-saving.

[0048] Specifically, the limiting component includes a second fixing plate 1801 fixed to one side of the guardrail 602. A second threaded tube 1802 is rotatably connected to the second fixing plate 1801. A second threaded rod 1803 is threadedly engaged with the second threaded tube 1802. A limiting plate 1804 is fixed to one end of the second threaded rod 1803, and a second handle 1805 is fixed to one end of the second threaded tube 1802. A guide component is provided between the second fixing plate 1801 and the limiting plate 1804 to guide the movement of the limiting plate 1804. The guide component includes multiple sleeves 1901 fixed to the second fixing plate 1801. A sliding rod 1902 is slidably connected to each sleeve 1901. The other end of the sliding rod 1902 is connected to the limiting plate 1804. Plate 1804 is fixed, and the second threaded tube 1802 is driven to rotate by the second handle 1805. During the rotation of the second threaded tube 1802, the limiting plate 1804 is driven to move by the meshing transmission between the second threaded tube 1802 and the second threaded rod 1803. During the movement of the limiting plate 1804, the limiting plate 1804 moves towards the main beam 2 and abuts against one side of the main beam 2 by the guiding action of the sleeve 1901 and the slide rod 1902. The limiting plates 1804 on both sides of the installation auxiliary frame body 6 abut against the two main beams 2 respectively, limiting the installation auxiliary frame body 6 after it is hoisted, so that the installation auxiliary frame body 6 can be operated and used more stably.

[0049] The specific working principle and process of this auxiliary frame are as follows:

[0050] After the prefabricated connecting beam 4 is placed in the connecting groove 5 of the two main beams 2, the installation auxiliary frame body 6 is lifted and moved by the external lifting equipment. During the lifting and moving process, the installation auxiliary frame body 6 is placed between the two main beams 2 and on one side of the connecting beam 4. During the lifting and placement of the installation auxiliary frame body 6, the support plates 802 of the four support rods 801 at the lower end of the two first fixing plates 7 abut against the upper end of the main beam 2. The support plates 802 support the entire installation auxiliary frame body 6, which facilitates the stable auxiliary construction operation of the installation auxiliary frame body 6.

[0051] After the installation auxiliary frame body 6 is hoisted between the two main beams 2, the second threaded tube 1802 is driven to rotate by the second handle 1805. During the rotation of the second threaded tube 1802, the limiting plate 1804 is driven to move by the mutual meshing transmission between the second threaded tube 1802 and the second threaded rod 1803. During the movement of the limiting plate 1804, the limiting plate 1804 moves towards the main beam 2 and abuts against one side of the main beam 2 by the guiding action of the sleeve 1901 and the slide rod 1902. The limiting plates 1804 on both sides of the installation auxiliary frame body 6 abut against the two main beams 2 respectively, limiting the installation auxiliary frame body 6 after hoisting, so that the installation auxiliary frame body 6 can be operated and used more stably.

[0052] After auxiliary formwork support and pouring are completed between the auxiliary frame body 6 and the main beam 2 and connecting beam 4, the auxiliary frame body 6 is moved between the two main beams 2 to assist in the construction of the connecting beam 4 at other positions between the two main beams 2. During the movement of the auxiliary frame body 6, the connecting shaft 1501 is driven to rotate through the labor-saving component. During the rotation of the connecting shaft 1501, the installation shaft 1201 is driven to rotate through the meshing transmission between the worm gear 1502 and the worm wheel 1503. During the rotation of the installation shaft 1201, the two installation shafts 1201 on the first installation box 11 are driven to rotate through the meshing transmission between the first gear 1401 and the second gear 1402. During the rotation of the two installation shafts 1201, the two first winding reels 1202 are driven to rotate. The rotation of the two first winding reels 1202 pulls and winds the pull rope 1203. During the pulling and winding of the two pull ropes 1203, the pull ropes 1203 drive the two first fixing plates 7. The first threaded tube 1002 rotates. During the rotation of the first threaded tube 1002, the sliding plate 901 is driven to move downward by the meshing transmission between the first threaded tube 1002 and the first threaded rod 1001 and the guiding effect of each support rod 801. The downward movement of the sliding plate 901 causes the rotating wheel 902 below each sliding plate 901 to abut against the upper end of the main beam 2. At this time, the rotating wheel 902 facilitates the movement of the installation auxiliary frame body 6 between the two main beams 2, and adjusts the usage position of the installation auxiliary frame body 6. This facilitates the auxiliary pouring and formwork of the connecting beam 4 at other positions between the two main beams 2 after the installation auxiliary frame body 6 is hoisted, eliminating the need to repeatedly hoist and move the installation auxiliary frame body 6, thus improving the construction efficiency of precast beam pouring. After the installation auxiliary frame body 6 has moved, the sliding plate 901 is driven to rise and reset. At this time, the installation auxiliary frame body 6 is supported by each support plate 802, which facilitates the stable use of the installation auxiliary frame body 6.

[0053] The method for casting precast beams using this auxiliary frame includes the following steps:

[0054] Step 1: Fix the main beam to the upper end of the support platform using a support frame. Set several connecting grooves at intervals on the main beam. After pouring, place both ends of the connecting beam in the connecting grooves.

[0055] Step 2: On the side of the connecting beam to be poured, an auxiliary frame for precast beam pouring and installation is erected between two adjacent main beams.

[0056] Step 3: Install the formwork for the connecting beams and pour the concrete.

[0057] Step 4: Activate the lifting assembly of the installation auxiliary frame, lower the moving assembly onto the main beam to bear the load, and move the installation auxiliary frame to the side of the next connecting beam to be poured;

[0058] Step 5: Repeat steps 3 and 4 until all connecting beams are poured.

[0059] Step 6: Remove the installation auxiliary frame to complete the construction.

[0060] After the precast beam casting and installation auxiliary frame is installed, adjust the limiting components of the auxiliary frame to be close to the side of the main beam. After the construction is completed, loosen the limiting components first, and then move the auxiliary frame.

[0061] After the auxiliary frame moves to the target position, the moving component is first raised to return to its initial state, so that the supporting component is subjected to force.

[0062] This invention relates to a precast beam casting and installation auxiliary frame. Through the cooperation of support components, moving components, lifting components, and driving components, the installation auxiliary frame body is easily moved between two main beams after being hoisted. The position of the installation auxiliary frame body can be adjusted, which facilitates the auxiliary casting and formwork of other connecting beams between the two main beams after the installation auxiliary frame body is hoisted. This eliminates the need for repeated hoisting and moving of the installation auxiliary frame body, thus improving the construction efficiency of precast beam casting.
