Description

Technical Field

[0001] This utility model relates to the field of bridge pier reinforcement protective layer control technology, specifically an auxiliary control device for pier protective layer. Background Technology

[0002] In the construction of bridge piers, the coordinates of the pier body need to be measured and located on the pier platform using a total station. Then, the formwork for the pier body is installed. After the formwork is installed, steel bars are erected inside the formwork, and then concrete is poured. There needs to be space between the steel bars and the inner wall of the formwork to prevent the steel bars from being exposed. After the concrete is poured, the concrete between the outermost wall of the pier body and the inner steel bars serves as a protective layer.

[0003] In existing technologies, concrete spacers are typically installed on the outer wall of the reinforcing bars to separate them from the inner wall of the formwork. However, conventional spacers require manual adjustment by prying the reinforcing bars with a crowbar, which is easy to get your hands caught and is labor-intensive. Moreover, the spacers are very prone to breakage during transportation, which has certain adverse effects on the use of the product. Therefore, we propose a device for controlling the thickness of the protective layer of reinforcing bars for bridge piers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary control device for the protective layer of pier columns, which has advantages such as easy installation and adjustment, and can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary control device for the protective layer of a pier column, comprising an auxiliary control device for auxiliary control of the protective layer of the pier column, wherein the auxiliary control device consists of a T-shaped screw and a rotating nut;

[0006] The rotating nut has a detachable torsion structure inside. The torsion structure includes a telescopically connected first sleeve and second sleeve, and a connecting end welded to one end of the second sleeve. The lower surface of the connecting end is fixedly installed with a locking block that engages with the inside of the rotating nut. The inside of the rotating nut has a locking groove that matches the locking block.

[0007] A measuring structure is fitted onto the outer surface of the T-shaped screw. The measuring structure includes a telescopic sleeve and a telescopic tube that are telescopically connected. A scale for measurement is provided on the outer surface of the telescopic tube.

[0008] Furthermore, the outer surface of the T-shaped screw and the inner side of the rotating nut are provided with matching threads.

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1 An auxiliary control device for the protective layer of a pier column includes an auxiliary control device 1 for auxiliary control of the protective layer of the pier column. The auxiliary control device 1 consists of a T-shaped screw 101 and a rotating nut 102. The outer surface of the T-shaped screw 101 and the inner side of the rotating nut 102 are provided with matching threads 103. The threads 103 are formed on the outer surface of the end of the T-shaped screw 101 away from the pier column reinforcement. The rotating nut 102 is threadedly connected to the T-shaped screw 101.

[0025] Specifically, the T-bolt 101 is fixed to the pier column reinforcement by welding. The welded connection has the advantages of simple structure, good sealing and high structural rigidity. It does not require drilling holes in the steel or auxiliary parts, which can make full use of the material and ensure the stability and reliability of the connection.

[0026] Furthermore, it has a strong load-bearing capacity. The welded connection and the design of the T-bolt 101 give the entire structure a high load-bearing capacity, enabling it to withstand large external forces and pressures, thus ensuring the safety and stability of the structure.

[0027] Example 2:

[0028] Please see Figures 1 to 3 Based on Embodiment 1, a torsion structure 2 is detachably installed inside the rotating nut 102. The torsion structure 2 is designed to be detachable, allowing for easy inspection, repair, or replacement of various components when needed, thereby extending the service life of the overall structure. The torsion structure 2 includes a telescopically connected first sleeve 201 and second sleeve 202, and a connecting end 203 welded to one end of the second sleeve 202. A locking block 204, which engages with the inside of the rotating nut 102, is fixedly installed on the lower surface of the connecting end 203. A slot 205, adapted to the locking block 204, is provided inside the rotating nut 102. The first sleeve 201 is hollow inside, with one end communicating with the outside. The end of the second sleeve 202 away from the connecting end 203 extends into the first sleeve 201. The hollow design of the first sleeve 201 not only saves material costs but also reduces the weight of the overall structure.

[0029] Specifically, both the first sleeve 201 and the second sleeve 202 have adjustment holes 206 inside, and positioning rods are inserted into the adjustment holes 206. The positioning rods inserted into the adjustment holes 206 allow for precise adjustment of the relative position between the first sleeve 201 and the second sleeve 202. This adjustment method is simple and effective, ensuring stable performance of the structure during use. Furthermore, adjusting the lengths of the first sleeve 201 and the second sleeve 202 makes it easier for operators to rotate the nut 102.

[0030] Example 3:

[0031] Please see Figure 4 Based on Embodiment 1, a measuring structure 3 is fitted onto the outer surface of the T-screw 101. The measuring structure 3 includes a telescopic sleeve 302 and a telescopic tube 303, which are telescopically connected. A scale 304 for measurement is provided on the outer surface of the telescopic tube 303. The scale 304 on the outer surface of the telescopic tube 303 allows the user to visually read the extension length of the telescopic tube 303, thereby achieving accurate measurement and positioning of the T-screw 101. A collar 301, which is fixed to the bottom end of the telescopic sleeve 302, is provided on the outer surface of the T-screw 101, and a locking bolt for fixing is installed inside the collar 301. The telescopic tube 303 is hollow inside, with an open top, and its bottom end extends into the interior of the telescopic tube 303. The locking bolt installed inside the collar 301 is used to fix the relative position of the telescopic sleeve 302 and the T-screw 101, ensuring that the measuring structure 3 will not loosen or fall off due to external forces during use.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the T-shaped screw 101 is welded to the pier column reinforcement, and then the clamp 204 is connected to the clamp slot 205. By rotating the twisting structure 2, the rotating nut 102 can be easily rotated. The thickness of the protective layer can be adjusted and controlled by rotating the nut 102. Then, by using the telescopic tube 303 in conjunction with the scale 304, the movement distance can be detected, so that the construction personnel can intuitively understand the current adjustment status and spacing.

[0034] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0035] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
