Description

Technical Field

[0001] The utility model belongs to the technical field of highway construction, and in particular relates to a portable ladder cage attachment, fixing and clamping device for high pier column construction. Background Art

[0002] During the construction of highway piers, the ladder cage is attached to the pier through a scaffold as a passage for the construction workers to go up and down. The stability of the ladder cage is related to the safety of the construction workers and the construction efficiency. At present, there is no special tool for the attachment and connection between the ladder cage and the pier. Ordinary scaffolding is usually used for crisscross fixing. The installation and disassembly is difficult, the process is cumbersome, and the installation is not in place, which causes the high pier ladder cage to shake, posing a safety hazard and affecting the construction efficiency. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a portable high pier construction ladder cage attachment fixing and clamping device which can adjust the appropriate ladder cage attachment spacing, quickly install and disassemble, and is stable and safe by utilizing the embedded climbing cone on the pier.

[0004] A portable ladder cage attachment, fixing and clamping device for high pier construction, comprising a U-shaped clamp sleeved on the ladder cage column, a U-shaped clamp bolt, a steel pipe scaffold fixed on the U-shaped clamp, a standard fastener, an attachment scaffold, and a steel plate with holes welded and attached to one end of the steel pipe scaffold; the steel plate at one end of the scaffold is fixedly connected to a climbing cone pre-buried in the pier column by bolts, and the other end is connected to the steel pipe scaffold by standard fasteners.

[0005] Furthermore, a cage attachment, fixing and clamping device is arranged on the high pier every 4.5 meters.

[0006] Furthermore, the steel pipe scaffolding is φ48mm and 40cm in length, welded to the back of the U-shaped clamp and arranged vertically with the ladder cage column.

[0007] Furthermore, the thickness of the steel plate is 10 mm, and the hole is capable of passing a φ32 mm bolt.

[0008] Furthermore, the climbing cone adopts a special embedded component for hollow pier formwork.

[0009] The utility model has the following beneficial effects:

[0010] The utility model connects the attachment scaffolding and the steel pipe scaffolding with standard fasteners, and adjusts the appropriate attachment spacing of the ladder cage according to construction needs; the standard fasteners are used to connect the attachment scaffolding and the steel pipe scaffolding, and the U-shaped clamps and U-shaped clamp bolts are sleeved on the ladder cage columns, so that the ladder cage is firmly attached to the high pier column, and the installation and disassembly are fast and simple, which ensures the safety of construction personnel and improves construction efficiency. After the construction is completed, it can be disassembled and used in a turnover manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the utility model;

[0012] Figure 2 It is a schematic diagram of the connection relationship between the ladder cage column and the high pier column of the utility model;

[0013] Figure 3 This is a diagram of the use status of the utility model during the construction of high pier columns. DETAILED DESCRIPTION

[0014] The content of the utility model is further described below in conjunction with the accompanying drawings and embodiments of the specification.

[0015] like Figure 1 , Figure 2 As shown, a portable ladder cage attachment, fixing and clamping device for high pier construction includes a U-shaped clamp 1 mounted on the ladder cage column B, a U-shaped clamp bolt 2, a steel pipe scaffold 3 fixed on the U-shaped clamp, a standard fastener 4, an attachment scaffold 5, and a steel plate 6 with a hole 61 welded to one end of the steel pipe scaffold; the steel plate at one end of the attachment scaffold is fixedly connected to the climbing cone pre-buried in the pier A through the hole 61 and the bolt 7, and the other end is connected to the steel pipe scaffold through the standard fastener. Connecting the steel pipe scaffold and the attachment scaffold through the standard fastener is a prior art, and the climbing cone is a connector with bolt holes pre-buried in the pier and is commercially available. The selection of the two makes it convenient for construction workers to obtain materials and install and disassemble. Figure 3 As shown, in order to more firmly attach and fix the ladder cage on it, a climbing cone is set every 4.5 meters on the high pier column to connect a ladder cage attachment and fixing clamping device, which is suitable for the construction of high piers; in a more optimal design, the steel pipe scaffolding is φ48mm and 40cm in length, welded on the back of the U-shaped clamp and vertically arranged with the ladder cage column, and the steel pipe scaffolding extends vertically out of the ladder cage column for easy connection with the attachment scaffolding 5. When connecting, the standard fasteners 4 are not only fast and simple to connect, but also can adjust the appropriate ladder cage attachment spacing according to construction needs. The standard fasteners are used to connect the attachment scaffolding and the steel pipe scaffolding, and the U-shaped clamps and U-shaped clamp bolts are sleeved on the ladder cage column. The ladder cage is firmly attached and fixed to the pier column to ensure the safety of construction personnel; the utility model designs the steel plate to be 10mm thick, and the holes on the steel plate are equipped with φ32mm bolts 7. The climbing cone adopts a special embedded component for the hollow pier template, which makes installation and disassembly faster and simpler, and can be used in a turnover manner after disassembly after construction.

[0016] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
