Description
Technical Field
[0001] This utility model relates to the field of waterway engineering construction technology, specifically to an auxiliary device for moving large-volume concrete formwork. Background Technology
[0002] In the construction of waterway projects, such as wharves and breakwaters, which involve a wide range of areas, it is necessary to pour high-strength, durable, and large-volume concrete slabs as the foundation structure. The volume of concrete to be poured is large and the construction period is long. In this process, large-volume concrete formwork is needed to support the large-volume concrete slabs. Its main function is to ensure that the concrete maintains the required shape and size during the pouring and solidification process, while bearing the weight and pressure of the concrete. It plays a vital role in concrete construction.
[0003] When pouring large-volume concrete slabs, their weight is significant. Therefore, extra care must be taken to ensure the stability of the supporting structure when constructing the formwork. In the current technology, given the numerous locations of large-volume concrete slabs involved in the construction, the formwork needs to be dismantled and rebuilt at each location. Since the formwork itself is large, dismantling and moving it not only consumes a lot of time, but also requires repeated adjustments to its position after manual handling or mechanical hoisting, thus reducing construction efficiency.

[0007] Preferably, the limiting mechanism includes a limiting sleeve fitted on the hydraulic jack, a limiting block provided on the side of the limiting sleeve, a limiting groove provided on the inner wall of the force transmission steel mold, and the limiting block slidably connected to the inner wall of the limiting groove.
[0008] Preferably, the side of the force-transmitting steel mold is provided with a through groove, the position of which corresponds to the position of the retracted hydraulic jack.
[0009] Preferably, the first shaping mold frame includes a frame body, on which angle steel retaining pads are welded, and the end of the connecting rod passes through the angle steel retaining pads and is installed thereon with a nut.

[0011] Preferably, the support includes a channel steel frame, and a bottom support frame is welded to the bottom of the channel steel frame. Both the channel steel frame and the bottom support frame are connected to the first shaping mold frame by means of pin bolts.
[0012] Preferably, the channel steel frame has an internal support frame welded inside, the internal support frame is provided with a positioning bolt, and the internal support frame is equipped with a connecting rod through the positioning bolt.
[0013] Preferably, the first shaping mold frame is divided into multiple groups, and each group of the first shaping mold frame is connected in series with steel pipes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This auxiliary device for moving large-volume concrete formwork uses a support and adjustment mechanism on a first formwork frame. A support frame is installed behind the first formwork frame using connecting rods and top rods. This allows the adjustment mechanism on the first formwork frame and the support frame to control the height, enabling the first formwork frame and the support frame to move. During construction, the first formwork frame can be moved nearby via the support frame and adjustment mechanism, allowing it to be moved to another large-volume concrete slab construction site without disassembling the first formwork frame. This provides quick support without requiring significant disassembly and assembly time. Furthermore, the pushing capability allows the first formwork frame to move directly without hoisting or transporting, further improving construction efficiency.
[0016] 2. This auxiliary device for moving large-volume concrete formwork, by connecting a second formwork frame in series between adjacent first formwork frames, allows for easy movement of the formwork by connecting adjacent first formwork frames and the second formwork frames between them into a group. Then, a support frame is installed behind the first formwork frame by using a top-mounted rod to pass over the concrete slab, so that the grouped first formwork frame can move together with the second formwork frame to the nearest concrete slab construction site, thus improving the ease of formwork construction.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6An auxiliary device for moving large-volume concrete formwork includes: a first formwork frame 1, a support frame 2 is provided at the rear of the first formwork frame 1, the first formwork frame 1 and the support frame 2 are connected by a connecting rod 3, the top of the first formwork frame 1 and the support frame 2 are installed by a top rod 4, and a bracket 5 is provided on both the first formwork frame 1 and the support frame 2, and an adjustment mechanism 6 is welded on the bracket 5;
[0026] The adjustment mechanism 6 includes a force transmission steel mold 61 welded to the support 5. A hydraulic jack 62 is installed inside the force transmission steel mold 61. A piston rod 63 on the hydraulic jack 62 is installed inside the force transmission steel mold 61. A wheel box 64 is installed at the bottom of the hydraulic jack 62. A roller 65 is rotatably installed inside the wheel box 64. The roller 65 is retracted into the force transmission steel mold 61 by the hydraulic jack 62. A limiting mechanism 66 is sleeved on the hydraulic jack 62.
[0027] The limiting mechanism 66 includes a limiting sleeve 661 fitted onto the hydraulic jack 62. A limiting block 662 is provided on the side of the limiting sleeve 661. A limiting groove 663 is provided on the inner wall of the force transmission steel mold 61. The limiting block 662 is slidably connected to the inner wall of the limiting groove 663. When the hydraulic jack 62 is in operation, the hydraulic jack 62 moves up and down in the force transmission steel mold 61 with the movement of the piston rod 63, so that the roller 65 set at the bottom of the hydraulic jack 62 can be directly extended, thereby giving the first shaping mold frame 1 the ability to move. Furthermore, when the hydraulic jack 62 moves, the limiting groove 663 provides a guiding function for the limiting block 662, limiting the movement path of the hydraulic jack 62 and avoiding the generation of torque force that could damage the hydraulic jack 62.
[0028] The force transmission steel mold 61 has a through groove 67 on its side. The position of the through groove 67 corresponds to the position of the retracted hydraulic jack 62. By opening the through groove 67, the control pipe of the hydraulic jack 62 can be directly connected to the outside. At the same time, it is convenient to inspect and maintain the hydraulic jack 62 after it is retracted.
[0029] The first shaping mold frame 1 includes a frame body 11, on which angle steel pads 12 are welded. The end of the connecting rod 3 passes through the angle steel pads 12 and is installed with them by nuts. By setting the angle steel pads 12 and installing them with one end of the connecting rod 3, the other end of the connecting rod 3 can cooperate with the top rod 4 after it is installed with the support frame 2, thereby increasing the stability of the first shaping mold frame 1 when it moves.
[0030] The frame 11 has a height adjustment mechanism 13 welded to its end and a top support frame 14 welded to its top. A pad frame 15 is installed on the top support frame 14. The top mounting rod 4 is installed on the pad frame 15 by bolts. After the first mold frame 1 is moved to the designated position, the frame 11 can be brought into contact with the ground by the height adjustment mechanism 13 after the hydraulic jack 62 is retracted, providing support for one end of the frame 11. The top support frame 14 and the pad frame 15 are then installed to increase the installation contact surface between the frame 11 and the top mounting rod 4, thereby improving the support capacity of the top mounting rod 4.
[0031] The support frame 5 includes a channel steel frame 51, and a bottom support frame 52 is welded to the bottom of the channel steel frame 51. Both the channel steel frame 51 and the bottom support frame 52 are connected to the first fixed mold frame 1 by setting pins 54. By setting pins 54, the support frame 5 can be connected with the adjustment mechanism 6 to become a detachable structure, so that the existing fixed mold frames on the market can be easily modified to install the moving auxiliary device. This makes the moving auxiliary device convenient to construct, low in modification cost, and improves work efficiency.
[0032] The channel steel frame 51 has an internal support frame 53 welded inside. The internal support frame 53 is equipped with a positioning bolt 55. The internal support frame 53 is connected to a connecting rod 7 via the positioning bolt 55. The positioning bolt 55 is installed on the bracket 5 so that adjacent first shaping mold frames 1 can be connected as one unit by installing the connecting rod 7. This ensures the stability of the first shaping mold frame 1 when it moves and prevents it from tipping over.
[0033] The first fixed formwork 1 is divided into multiple groups, and each group of first fixed formwork 1 is connected by steel pipes. Multiple second fixed formwork 8 are connected in series on the steel pipes between adjacent first fixed formwork 1 groups. When moving the formwork, it is only necessary to connect the adjacent first fixed formwork 1 and the second fixed formwork 8 between them into a group. Then, the support frame 2 is installed behind the first fixed formwork 1 by the top mounting rod 4 over the concrete slab, so that the grouped first fixed formwork 1 can move together with the second fixed formwork 8 to the nearest concrete slab construction site, which improves the convenience of fixed formwork construction.
[0034] The working principle is as follows: after the construction of a concrete slab is completed, when the formwork is dismantled to construct the next concrete slab, two adjacent first formwork frames 1 and the second formwork frame 8 sandwiched between them can be connected into one unit using steel pipes. The two adjacent first formwork frames 1 are fixedly installed by the connecting rod 7. Then, the top mounting rod 4 is used to cross the concrete slab and the support frame 2 is installed behind the first formwork frame 1. The height of a set of formwork is then raised by the adjustment mechanism 6, so that a set of formwork can be directly pushed along the direction of the concrete slab to the next construction position, thereby quickly supporting the next construction site.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
