Description

Technical Field

[0001] The utility model belongs to the field of subway station construction, and particularly relates to a supporting device and a side wall steel bar protective layer. Background Art

[0002] Controlling the thickness of subway side wall reinforcement and adjusting the reinforcement skeleton are key links in ensuring structural safety and construction quality.

[0003] In existing technology, the side wall reinforcement cover within the side wall is constructed by welding several short steel bars vertically between the two sides of the reinforcement skeleton to support the skeleton. Spacers are attached to the outside of the reinforcement skeleton. When making the side wall reinforcement cover, construction workers first use a tape measure to measure the distance between the side wall formwork and the ground tie wall to determine the required short steel bar length. After welding the short steel bars, they can tap and adjust the bent short steel bars to support the reinforcement skeleton, ensuring that the spacers fit the formwork and that the qualified rate of the side wall reinforcement cover meets the requirements.

[0004] The drawbacks of this method are that it relies heavily on manual labor, which is not only inefficient but also difficult to ensure accuracy and consistency. Furthermore, the complex construction site environment requires a portable, durable, and easy-to-use tool to assist in completing these tasks. Furthermore, when measuring the distance between the side wall formwork and the ground-connected wall, construction workers cannot maintain a vertical ruler, resulting in inaccurate measurements. This can cause the rebar to be too long or too short during welding. Excessive length can damage the spacers and waterproofing membranes, while excessive shortness can prevent the support structure from being erected, leading to repetitive work.

[0005] Therefore, it is crucial to provide a supporting device to effectively solve the problems of difficulty in controlling the thickness of the steel bar cover and low efficiency of manual adjustment. Utility Model Content

[0025] like Figure 3 、 Figure 4 As shown, the side wall steel bar protection layer includes steel bar skeletons on both sides and a plurality of supporting devices arranged between the steel bar skeletons on both sides.

[0026] like Figure 1 、 2 The supporting device shown includes a telescopic rod 1 with adjustable length, and a first connecting device 13 and a second connecting device 14 provided at both ends of the telescopic rod 1 and capable of connecting with corresponding steel bar skeletons respectively.

[0027] The first connecting device 13 and the second connecting device 14 are both slot-type buckles, which are quick-matching structures and are convenient for construction workers to quickly install and disassemble on site.

[0028] The first connecting device 13 and the second connecting device 14 are respectively connected and fitted to the steel bars of the steel bar skeleton on the corresponding side.

[0029] The telescopic rod 1 comprises an outer tube 11 and an inner tube 12 that is telescopically disposed within the outer tube 11 to adjust its length. Both the outer tube 11 and the inner tube 12 are made of an aluminum alloy, a lightweight, high-strength material that is painted for enhanced wear and corrosion resistance. This ensures sufficient mechanical strength, ease of portability, and the ability to withstand long-term use without deformation or damage.

[0030] Example 1: Figure 1 As shown, the telescopic rod 1 is a screw-type manual telescopic rod. The inner tube 12 and the outer tube 11 are threaded together to rotate and extend. The first connecting device 13 is rotatably mounted on the corresponding end of the outer tube 11, and the second connecting device 14 is fixed to the corresponding end of the inner tube 12. A flat surface is milled along the length of the inner tube 12, and a length scale is provided on the flat surface.

[0031] The inner surface of the outer tube 11 has an internal thread, and the inner tube 12 is a screw with an external thread on the outer surface. The external thread of the inner tube 12 is matched with the internal thread on the inner surface of the outer tube 11. The total length between the outer tube 11 and the inner tube 12 can be adjusted by rotating the outer tube 11.

[0032] Although not shown, the telescopic rod 1 may also be a linear manual telescopic rod, with a handle between the outer tube 11 and the inner tube 12 for tightening the two. By tightening the handle, the position between the outer tube 11 and the inner tube 12 is locked at a required length.

[0033] Example 2: Figure 2 As shown, the telescopic rod 1 is an electric telescopic rod, and the inner tube 12 can only be slidably arranged in the outer tube 11. The telescopic rod 1 also includes a motor 15 arranged in the outer tube 11 and a drive rod 16 with one end fixed to the output shaft of the motor 15. The inner tube 12 and the drive rod 16 are threadedly matched.

[0034] The support device also includes a mobile battery pack 2 for powering the motor, a power cord 3 having one end electrically connected to the mobile battery pack 2, a switch assembly 4 being provided on the power cord, and a power interface being provided on the outer tube 11 to be plugged into the other end of the power cord, which is used to power the motor 15 after connection. By adopting an electric drive, the positioning efficiency of the side wall protective layer is improved, and the adjustment process is simplified. Accurate and rapid adjustment is achieved through electric drive, thereby quickly and effectively controlling the thickness of the side wall concrete protective layer, improving adjustment efficiency and accuracy. The control switch assembly 4 is a magnetic switch, which is convenient for construction workers to use in complex environments and is not affected by water, oil, ice, dirt, etc.; the motor has overload protection and automatic power-off functions to ensure safe use.

[0035] Not shown, the length markings include an inner tube marking on the inner tube 12, which extends from the extended end of the inner tube 12 toward the outer tube 11. Also included is a marking on the outer tube 11 that indicates the total length of the outer tube 11. The total length of the telescopic rod is the sum of the extended length of the inner tube 12 and the total length of the outer tube 11. The markings are laser-engraved with high precision, offering wear and corrosion resistance. They remain clearly visible even after long-term use, allowing construction workers to precisely control the telescopic length and improving construction accuracy and consistency.

[0036] Working principle: During construction, first, the electric telescopic rod is matched or matched with the steel frame through the connecting devices at both ends; the motor is started by controlling the button, and the motor drives the inner rod to extend and retract inside the outer rod, and is adjusted to the required length according to the scale mark; after the telescopic rod is adjusted into place, its sturdy and durable characteristics are used to maintain a stable position, assisting in completing the control of the thickness of the steel cover and the adjustment of the steel frame.
