Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a hollow pier inner formwork operating platform. Background Art

[0002] In the field of bridge engineering, hollow piers are increasingly used as a structural optimization design. The main feature of hollow piers is that they are made of concrete or reinforced concrete materials to form a hollow thin-walled structure, such as Figure 4 As shown in the figure. This design not only reduces the deadweight of the pier, but also improves the stability and bearing capacity of the structure. Since the interior of the hollow pier is usually designed to gradually widen from bottom to top, the internal space size of the hollow pier is inconsistent at different heights.

[0003] Traditional working platforms are often designed with fixed specifications, which are difficult to meet the changing space requirements inside the hollow pier. The construction team has to design and build multiple working platforms of different specifications according to the different positions of the hollow pier. This approach not only increases the complexity of construction, but also significantly increases the construction cost. Therefore, we propose a hollow pier inner mold working platform to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0024] The present application provides a hollow pier inner mold work platform, which is mainly used to solve the problem that the traditional work platform in the prior art is often designed with fixed specifications, which is difficult to meet the variable space requirements inside the hollow pier. The construction team has to design and build multiple work platforms of different specifications according to the different positions of the hollow pier. This practice not only increases the complexity of construction, but also significantly increases the construction cost. The following technical solutions are provided. Figure 1-Figure 3 Make a detailed description:

[0025] A hollow pier inner mold working platform, comprising:

[0026] Hollow plate 1, both ends of the hollow plate 1 are open structures, and strip-shaped through holes 101 are constructed on both sides of the top of the hollow plate 1:

[0027] The slide plate 2 is symmetrically slidably inserted into the hollow plate 1, and an extension plate 3 is fixedly provided at an equal interval on one side of the slide plate 2 close to the outside of the hollow plate 1;

[0028] A steel wire rope 4 is connected to one end of the extension plate 3 located outside the slide plate 2, and a connecting piece 5 for connecting to the inner wall of the hollow pier is provided at the free end of the steel wire rope 4;

[0029] The locking mechanism 6 is arranged at the strip-shaped through hole 101 and is used to fix the slide plate 2 at a specified position. The locking mechanism 6 includes bolts 601 fixedly arranged on both sides of the top of the slide plate 2. A limiting plate 602 is placed at the position of the top of the hollow plate 1 corresponding to the strip-shaped through hole 101. Limiting holes 6021 are arranged at equal intervals on both sides of the limiting plate 602. One end of the bolt 601 away from the slide plate 2 passes through the strip-shaped through hole 101 and the limiting hole 6021 in sequence, and a locking nut 603 is threadedly connected to the end thereof.

[0030] The bearing table 7 is laid on the top of the hollow plate 1, and the length of the bearing table 7 is adjustable.

[0031] Working principle description:

[0032] The hollow pier inner mold working platform adjusts the base length through the sliding mechanism of the slide plate 2 inside the hollow plate 1. The staff can adjust the length of the extension plate 3 protruding from the hollow plate 1 according to actual needs to adapt to the spatial dimensions of different positions inside the hollow pier. The locking mechanism 6 ensures that the slide plate 2 can be firmly locked after being adjusted to the appropriate position to prevent sliding through the coordinated use of the bolt 601 and the limit hole 6021. The length of the load-bearing table 7 is adjustable to adapt to working areas of different widths. The wire rope 4 is connected to the pull ring on the inner wall of the hollow pier through a hook, providing additional stability for the working platform to ensure that the platform will not shift or tip over during construction. The hollow pier inner mold working platform effectively solves the limitation that traditional working platforms cannot adapt to changes in the internal space of the hollow pier through its unique design and flexible adjustment mechanism, thereby improving construction efficiency and reducing costs.

[0033] like Figure 2 As shown, in some embodiments, the connecting member 5 is a hook, and pull rings compatible with the hooks are pre-embedded at equal intervals on the inner wall of the hollow pier. More specifically, the provision of the pre-embedded pull rings allows workers to quickly connect the hooks with them, greatly reducing the time for building the work platform. When the position of the work platform needs to be adjusted, the design of the hook and the pull ring is also convenient for disassembly and reconnection, thereby improving the flexibility of construction. The combination of the hook and the pull ring can effectively prevent accidental slippage during construction and ensure the safety of the workers.

[0034] like Figure 1 As shown, in some embodiments, a fixed plate 8 is connected to the front and rear corners of the hollow plate 1, and a lifting lug 9 is provided on the top of the fixed plate 8. More specifically, when the height of the operating platform needs to be adjusted, the staff can connect the traction rope of the crane to the lifting lug 9, and then assemble and disassemble the hook and the pull ring.

[0035] like Figure 3 As shown, in some embodiments, the bearing table 7 includes a main steel mesh 701 placed in the middle of the top of the hollow plate 1, and a plurality of secondary steel meshes 702 are detachably connected to both sides of the main steel mesh 701, and the main steel mesh 701 is connected to the secondary steel mesh 702 and the adjacent secondary steel meshes 702 by self-locking hooks 703. More specifically, the bearing table 7 is composed of a main steel mesh 701 and a plurality of secondary steel meshes 702, and its length can be adjusted by adding or reducing the secondary steel meshes 702 to adapt to working areas of different widths. The connection method of the self-locking hook 703 provides a stable locking mechanism to ensure that the connection between the main steel mesh 701 and the secondary steel mesh 702 and between the adjacent secondary steel meshes 702 is firm and reliable, thereby enhancing the stability and safety of the entire bearing table 7. It should be noted that the self-locking hook 703 is a prior art and its working principle is not described in detail.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
