[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-2 This utility model describes a device for adjusting the protective layer of reinforcing bars in a pier.

[0026] This embodiment provides a device for adjusting the protective layer of the pier reinforcement, including: a template, a thrust member, and a limiting device.

[0027] The template is set on the outside of the pier reinforcement, the thrust member is movably set between the template and the pier reinforcement, and the thrust member can contact the outside of the pier reinforcement. The limiting device is set between the thrust member and the template, and the limiting device contacts the side of the thrust member away from the pier reinforcement. It is used to fix the thrust member in the required position when the thrust member contacts the outside of the pier reinforcement.

[0028] This configuration, through the movable design of the thrust member, allows for the positioning of different sizes of pier reinforcement and concrete cover thickness. The position of the thrust member can be adjusted according to design requirements to ensure close contact with the outer side of the pier reinforcement, and the thrust member can be fixed in the required position by the limiting device. This enables precise control of the pier reinforcement cover thickness and avoids quality problems caused by uneven cover thickness.

[0029] In this embodiment, the template is set according to the outer contour shape of the pier reinforcement, and the whole is waist-shaped. The template includes an arc template 10, which is located at both ends of the template and can be in the form of a semi-circular structure. The arc template 10 corresponds to the arc segment of the pier reinforcement. The thrust member includes a first thrust member 11, which is movably set between the arc template 10 and the arc segment of the pier reinforcement, and the first thrust member 11 can contact the outer side of the arc segment of the pier reinforcement.

[0030] This configuration allows for accurate positioning of the curved segment of the pier reinforcement through the first thrust member 11. By contacting the curved segment of the pier reinforcement with the first thrust member 11, the pier reinforcement is prevented from approaching the curved template 10, ensuring that the thickness of the protective layer between the curved segment of the pier reinforcement and the curved template 10 meets the construction requirements. This reduces errors caused by human factors, improves the overall construction quality, and the mobility of the first thrust member 11 allows for fine-tuning of its position during installation to adjust the thickness of the protective layer according to actual needs.

[0031] Reference Figure 1 In this embodiment, the limiting device includes an adjusting rod 12, a positioning nut 13, and a first fixing member 14. The first fixing member 14 is connected to the arc-shaped template 10, the positioning nut 13 is threadedly connected to the adjusting rod 12, one end of the adjusting rod 12 abuts against the first fixing member 14, the first thrust member 11 passes through the adjusting rod 12, one side of the first thrust member 11 abuts against the positioning nut 13, and the other side of the first thrust member 11 is used to contact the outer side of the arc-shaped section of the pier reinforcement. The axial direction of the adjusting rod 12 is the same as the radial direction of the arc-shaped section of the pier reinforcement. In other words, by contacting the first thrust member 11 with the arc-shaped section of the pier reinforcement, the arc-shaped section of the pier reinforcement is fixed in position. The first fixing member 14 can withstand the axial force transmitted by the pier reinforcement through the adjusting rod 12, prevent the adjusting rod 12 from moving axially, and fix the arc-shaped section of the pier reinforcement in the current position. The installation and position adjustment of the first thrust member 11 are completed by adjusting the position of the positioning nut 13 on the adjusting rod 12. Moreover, the threaded connection can play an anti-loosening role and prevent the positioning nut 13 from moving in the opposite direction after positioning.

[0032] In some embodiments, the first fixing member 14 includes a connecting part 141 and a fixing part 142. The connecting part 141 is connected to the arc-shaped template 10, and the fixing part 142 abuts against the end of the adjusting rod 12. For example, the first fixing member 14 is an angle steel. One end of the angle steel is fixedly connected to the arc-shaped template 10, and the other end of the angle steel is used to abut against the end of the adjusting rod 12 to provide a reverse force to the adjusting rod 12, fix the first thrust member 11 in the desired position, and prevent the arc-shaped section of the pier reinforcement from approaching the arc-shaped template 10.

[0033] Optionally, the connecting part 141 is detachably connected to the arc-shaped template 10. For example, the top of the arc-shaped template 10 is provided with a plurality of first fixing holes, and the connecting part 141 is provided with a corresponding first connecting hole. The connecting part 141 is connected to the arc-shaped template 10 by passing a bolt through the first connecting hole and the first fixing hole.

[0034] This design ensures the construction quality of the pier reinforcement and protective layer, and facilitates their removal after construction, allowing for multiple uses.

[0035] Furthermore, the template in this embodiment also includes a straight template 20, which corresponds to the straight segment of the pier reinforcement; the thrust member includes a second thrust member 21, which is movably disposed between the straight template 20 and the straight segment of the pier reinforcement, and the second thrust member 21 can contact the outer side of the straight segment of the pier reinforcement.

[0036] This configuration allows for accurate positioning of the straight section of the pier reinforcement through the second thrust member 21. By contacting the straight section of the pier reinforcement with the second thrust member 21, the pier reinforcement is prevented from approaching the straight formwork 20, ensuring that the thickness of the protective layer between the straight section of the pier reinforcement and the straight formwork 20 meets the construction requirements. This reduces errors caused by human factors, improves the overall construction quality, and the mobility of the second thrust member 21 allows for fine-tuning of its position during installation to adjust the thickness of the protective layer according to actual needs.

[0037] In some embodiments, the limiting device includes a second fixing member 22 and a positioning bolt. One end of the second fixing member 22 is connected to the straight template 20, and the other end of the second fixing member 22 is provided with an adjustment hole 23. The adjustment hole 23 extends in a direction perpendicular to the straight template 20, and the positioning bolt is disposed in the adjustment hole 23, abutting against the second thrust member 21. That is, the adjustment hole 23 extends in a direction perpendicular to the straight template 20, allowing the positioning bolt to be freely adjusted in this direction. By adjusting the position of the positioning bolt in the adjustment hole 23, the installation and fixed position adjustment of the second thrust member 21 are completed. Then, by the second thrust member 21 contacting the straight section of the pier reinforcement, the position of the straight section of the pier reinforcement is fixed, thereby realizing the adjustment of the distance between the straight section of the pier reinforcement and the straight template 20, so as to meet the construction requirements for the thickness of the protective layer of the pier reinforcement. The straight template 20 provides a reverse force to the second fixing member 22 to ensure that the limiting device will not shift or loosen.

[0038] With this configuration, the rigid structure of the straight template 20 can effectively resist deformation that may occur during construction, thereby ensuring the straightness of the steel reinforcement installation. This helps to maintain the stability and positional accuracy of the steel reinforcement during installation, ensures that the thickness of the protective layer of the pier reinforcement meets the construction requirements, and reduces the risk of safety accidents caused by steel reinforcement displacement or tipping.

[0039] like Figure 2 As shown, in some embodiments, the second thrust member 21 is a horizontally arranged stop bar. The stop bar can contact multiple positioning bolts simultaneously, and the stop bar is used to contact the vertical reinforcing bars in the pier body. By setting a stop bar, the position of multiple vertical reinforcing bars can be fixed.

[0040] like Figure 2 As shown, the second fixing member 22 is a strip plate, and the length direction of the second fixing member 22 is perpendicular to the length direction of the straight template 20.

[0041] Optionally, the straight template 20 and the second fixing member 22 can be detachably connected. For example, the top of the straight template 20 is provided with a plurality of second fixing holes, and the second fixing member 22 is provided with a corresponding second connecting hole. The second fixing member 22 is connected to the straight template 20 by passing a bolt through the second connecting hole and the second fixing hole.

[0042] The standardization and reusability of the thrust stop and limiting device of this invention reduce material consumption and waste generation, and help achieve green construction and cost control.
