Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a built-in supporting bracket structure suitable for thin-walled hollow piers. Background Art

[0002] Traditional thin-walled hollow piers use flip-over mold construction, and the working platform is mainly made of simple bamboo springboards or scaffolding built by hand. In actual construction, the turnover of large quantities of scaffolding brings more safety risks, especially in environments affected by typhoons, monsoons, and low temperatures. The working environment of workers is poor, the effective working time in the field is limited, the work efficiency is greatly reduced, the safety risks are multiplied, and the construction quality is difficult to control. Therefore, a new, highly stable and safe built-in fully enclosed operating platform for thin-walled hollow piers is needed.

[0003] The built-in fully enclosed operating platform requires built-in corbels as supporting components. In the prior art, utility model patent CN217923148U discloses an assembled corbel suitable for bridge support construction, including: a climbing cone screw and a positioning steel plate. The climbing cone screw penetrates the positioning steel plate and is installed at a specific position on the bridge pier. Two positioning steel plates are arranged on the left and right, and the front and rear positions are adjustable. They are welded and connected to the vertical main reinforcement of the pier body to position the steel corbels and the climbing cone screws, and prevent misalignment and deviation during the pouring of the pier concrete. The climbing cone head is installed on the outside side of the climbing cone screw pier body, and the steel corbel is fastened to the climbing cone head through a climbing cone nut. However, the assembled corbel has the following shortcomings:

[0004] 1. The bracket is used to support the bracket outside the bridge pier, not to support the internal operating platform;

[0005] 2. The mounting holes on the corbel are regular circles, and there are multiple of them. This makes it difficult to quickly align the climbing cone screw with the mounting hole when installing the corbel, making the installation difficult. Utility Model Content

[0006] The utility model aims to address the above shortcomings and provide a built-in supporting corbel structure suitable for thin-walled hollow piers, thereby improving the installation and disassembly efficiency of the corbel.

[0007] The purpose of the utility model is achieved in this way:

[0008] A built-in supporting corbel structure suitable for a thin-walled hollow pier comprises a corbel body and a fixing piece, wherein the corbel body is fixed to the inner side of the thin-walled hollow pier through the fixing piece.

[0009] In certain embodiments, the corbel body includes a vertically arranged mounting member and a transverse support member vertically connected to the top end of the mounting member, and the transverse support member and the mounting member are further connected via an obliquely arranged reinforcement member.

[0010] In certain embodiments, the angle between the reinforcement member and the lateral support member is 45°.

[0011] In certain embodiments, the mounting member is provided with a mounting hole and a slot that are interconnected, the mounting hole is located above the slot, and the inner diameter of the slot is larger than the inner diameter of the mounting hole.

[0012] In certain embodiments, the fixing member includes a climbing cone pre-embedded in the precast concrete segment and a screw rod matched with the climbing cone, and the screw rod passes through the mounting member and is connected to the climbing cone.

[0013] In certain embodiments, the screw rod passes through the mounting hole and is connected to the climbing cone.

[0014] In certain embodiments, a gasket is disposed between the mounting member and the nut of the screw rod, and a diameter of the gasket is larger than an inner diameter of the mounting hole.

[0015] In certain embodiments, the outer diameter of the screw nut is smaller than the inner diameter of the slot and larger than the inner diameter of the mounting hole.

[0016] The beneficial effects of the utility model are:

[0017] The supporting corbel structure of the utility model is installed on the inner side of the thin-walled hollow pier and has high stability. An operating platform can be placed on it, thereby improving the stability of the operating platform and reducing the safety risk compared with the traditional inner mold installation of the operating platform. On the other hand, the utility model provides a card slot with a larger aperture below the installation hole. When installing the corbel body, the corbel body first passes through the card slot through the screw rod, and then falls under the action of gravity, allowing the screw rod to pass through the installation hole. This allows the corbel body to be installed on the fixing part as a whole by hoisting, thereby improving the installation and disassembly efficiency compared with traditional scaffolding.

[0026] By arranging the corbel body 1 on the inner side of the hollow pier, it is convenient to subsequently build an operating platform on the corbel body 1, so that the operating platform is located inside the hollow pier. The size of the operating platform can be set to be close to the internal plane of the hollow pier, so that construction personnel can work inside the entire hollow pier, which greatly increases the working space. Compared with the traditional scaffolding construction during the construction, the safety is greatly improved.

[0030] In some preferred embodiments, the angle between the reinforcement member 5 and the transverse support member 4 is 45°, and the reinforcement member 5 is 8-15 cm away from the end of the transverse support member 4 away from the mounting member 3, so that the structure of the corbel body is more stable.

[0031] In some preferred embodiments, the mounting member 3 is provided with a mounting hole 6 and a slot 7 that are interconnected, the mounting hole 6 is located above the slot 7 and the inner diameter of the slot 7 is larger than the inner diameter of the mounting hole 6, so that the installation and disassembly of the corbel body 1 is facilitated.
