Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a non-destructive and efficient adjustment device for the thickness of the protective layer of a pier column. Background Technology

[0002] During the construction of bridge piers and box girders, steel reinforcement cages or skeletons are required. To prevent corrosion of the steel reinforcement, a certain thickness of the protective layer is necessary to protect it from rust and extend the service life of the project. Therefore, the thickness adjustment device for the protective layer of bridge pier pouring is an important construction component. Currently, when raising the strength pads for the protective layer of the pier reinforcement cage, manual steel pry bars are used. However, this method is inconvenient because it is done inside the formwork in a confined space. Secondly, the point stress can easily deform the reinforcement cage, resulting in uneven and highly volatile protective layer test data. Thirdly, it can cause irreversible scratches on the stainless steel surface, affecting the appearance of the concrete and reducing the turnover rate of the formwork. Utility Model Content

[0003] To facilitate the adjustment of the protective layer thickness and reduce the probability of deformation of the reinforcing cage and scratches on the formwork, this application provides a non-destructive and efficient adjustment device for the protective layer thickness of pier columns.

[0004] This application provides a non-destructive and efficient adjustment device for the protective layer thickness of pier columns, which adopts the following technical solution:

[0005] A non-destructive and efficient adjustment device for the protective layer thickness of a pier column includes two support bars, both of which are located between the reinforcing cage and the formwork. The ends of the two support bars that are close to each other are fixedly connected to a nut, and an adjusting screw is threaded into the nut.

[0006] By adopting the above technical solution, when adjusting the thickness of the protective layer of the pier column, first place two support bars between the steel cage and the formwork. At this time, both support bars are in contact with the steel bars on the steel cage. Then, manually rotate the adjusting screw. The end of the adjusting screw close to the formwork is in contact with the formwork and moves the formwork away from the steel cage. When it moves to the specified distance, place the shim between the steel cage and the formwork. This realizes the adjustment of the thickness of the protective layer of the pier column, improves the construction efficiency and quality in a narrow space, and reduces the probability of deformation of the steel cage and scratches on the formwork.

[0007] Optionally, a handle is fixedly connected to the end of the adjusting screw away from the template.

[0008] By adopting the above technical solution, the handle makes it easier to rotate the adjusting screw, thereby improving construction efficiency.

[0009] Optionally, a reinforcing mechanism is also installed on the support bar. The reinforcing mechanism includes a slider. Two grooves are opened on the side wall of the slider. The slider is slidably connected to the two support bars through the two grooves. An arc-shaped groove is opened along the length direction on the end face of the slider away from the template. The outer ring steel bar of the steel cage is located in the arc-shaped groove.

[0010] By adopting the above technical solution, the arc-shaped groove on the slider is used to fix the support bar, thereby reducing the probability that the support bar will rotate when the adjusting screw is rotated, and thus improving the adjustment stability of the entire device.

[0011] Optionally, the sidewalls at both ends of the slider are provided with first screw holes, and the two first screw holes are respectively connected to the two slide grooves. The reinforcement mechanism also includes two tightening bolts, which are respectively threaded into the two first screw holes.

[0012] By adopting the above technical solution, when fixing the support bar, manually slide the slider to the position of the annular steel bar on the outside of the steel cage, and then fix the slider through the arc groove. At this time, manually rotate the tightening bolt, and the tightening bolt will press the slider against the support bar.

[0013] Optionally, a tightening mechanism is installed at one end of the adjusting screw near the template. The tightening mechanism includes an arc-shaped block and a rotating assembly. The arc-shaped block is mounted on the adjusting screw via the rotating assembly, and the rotating assembly is mounted on the arc-shaped block via a fixing assembly.

[0014] By adopting the above technical solution, since the top of the adjusting screw covers a small area of ​​the inner wall of the template, when the adjusting screw is rotated, the template only moves partially away from the reinforcing cage, making it difficult to insert the spacer. The arc-shaped block increases the contact area between the adjusting screw and the template, so that when the adjusting screw is rotated, the entire end face of the template moves away from the reinforcing cage, making it easier to insert the spacer and improving the efficiency of adjusting the thickness of the protective layer of the pier column.

[0015] Optionally, the rotating assembly includes a connecting block, which is mounted on the arc-shaped block via the fixing assembly. A rotating groove is formed on the end face of the connecting block away from the arc-shaped block, and a limiting groove is formed on the side wall of the rotating groove. A slot is also formed on the end face of the connecting block away from the arc-shaped block, and the slot communicates with the limiting groove. A limiting block is fixedly connected to the side wall of the adjusting screw, and the limiting block is rotatably connected to the limiting groove through the slot. A first annular block is also slidably connected to the adjusting screw, and an insert is fixedly connected to one end of the first annular block near the connecting block. The end of the insert, away from the first annular block, is inserted into the slot. The rotating assembly also includes a first fixing bolt, which passes through the first annular block and is threadedly connected to the connecting block.

[0016] By adopting the above technical solution, when adjusting the thickness of the protective layer of the pier column, first place the arc-shaped block between the template and the reinforcing cage and abut against the inner wall of the template. Then, insert the adjusting screw into the rotating groove. At this time, the adjusting screw drives the limiting block to be inserted into the limiting groove. Then, the first annular block abuts against the connecting block. At this time, the first annular block drives the insert block to be inserted into the slot. Then, the first annular block is installed on the connecting block through the first fixing bolt. At this time, rotate the adjusting screw. The adjusting screw drives the template to move through the arc-shaped block, thereby realizing the adjustment of the thickness of the protective layer of the pier column.

[0017] Optionally, the fixing component includes a second annular block, which is fixedly connected to the connecting block. The fixing component also includes a second fixing bolt, which passes through the second annular block and is threaded onto the arc-shaped block.

[0018] By adopting the above technical solution, the second annular block and the second fixing bolt enable the detachable connection between the connecting block and the arc block, which facilitates the replacement of arc blocks with different curvatures according to the curvature of the template, thereby improving the applicability of the entire device.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. When adjusting the thickness of the protective layer of the pier column, first place two support bars between the steel cage and the formwork. At this time, both support bars are in contact with the steel bars on the steel cage. Then, manually rotate the adjusting screw. The end of the adjusting screw close to the formwork is in contact with the formwork and moves the formwork away from the steel cage. When it moves to the specified distance, place the shim between the steel cage and the formwork. This achieves the adjustment of the thickness of the protective layer of the pier column, improves the construction efficiency and quality in a narrow space, and reduces the probability of deformation of the steel cage and scratches on the formwork.

[0021] 2. The arc-shaped groove on the slider fixes the support bar, thereby reducing the probability that the support bar will rotate when the adjusting screw is rotated, thus improving the adjustment stability of the entire device;

[0022] 3. The arc-shaped block increases the contact area between the adjusting screw and the template, which in turn causes the entire end face of the template to move away from the reinforcing cage when the adjusting screw is rotated, making it easier to insert the pad and improving the efficiency of adjusting the thickness of the protective layer of the pier column.

[0023] 4. The second annular block and the second fixing bolt enable the detachable connection between the connecting block and the arc block, which facilitates the replacement of arc blocks with different curvatures according to the curvature of the template, thus improving the applicability of the entire device.

[0030] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0031] This application discloses a non-destructive and efficient adjustment device for the thickness of the protective layer of a pier column.

[0032] Example 1:

[0033] refer to Figure 1 The non-destructive and efficient adjustment device for the protective layer thickness of the pier column includes two support bars 3. Both support bars 3 are located between the steel cage 1 and the formwork 2. The ends of the two support bars 3 that are close to each other are fixedly connected to nuts 4. The nuts 4 are threadedly connected to adjusting screws 5. The end of the adjusting screws 5 that is away from the formwork 2 is fixedly connected to a handle 6.

[0034] The implementation principle of Embodiment 1 of this application is as follows: When adjusting the thickness of the protective layer of the pier column, first place two support bars 3 between the steel cage 1 and the formwork 2. At this time, both support bars 3 are in contact with the steel bars on the steel cage 1. Then, manually rotate the adjusting screw 5. The end of the adjusting screw 5 close to the formwork 2 is in contact with the formwork 2 and drives the formwork 2 to move away from the steel cage 1. After moving to the specified distance, place the shim between the steel cage 1 and the formwork 2, thereby realizing the adjustment of the thickness of the protective layer of the pier column, improving the construction efficiency and construction quality in a narrow space, and reducing the probability of deformation of the steel cage 1 and scratches on the formwork 2.

[0035] Example 2:

[0036] refer to Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that a reinforcing mechanism 7 is installed on the support bar 3. The reinforcing mechanism 7 includes two sliders 71. Two through grooves 712 are opened on the side walls of the two sliders 71. The two sliders 71 are slidably connected to the two support bars 3 through the two grooves 712. Arc grooves 711 are opened along the length direction on the end face of the two sliders 71 away from the template 2. The outer ring steel bar of the steel cage 1 is located in the arc grooves 711. First screw holes 713 are opened on the side walls at both ends of the two sliders 71. Tightening bolts 72 are threaded into the four first screw holes 713.

[0037] When fixing the support bar 3, first slide the two sliders 71 to the outer ring bar of the steel cage 1, then snap the outer ring bar of the steel cage 1 into the arc groove 711, and then manually rotate the tightening bolt 72. The tightening bolt 72 tightens the support bar 3, thereby fixing the slider 71 on the support bar 3. This reduces the probability that the support bar 3 will rotate when the adjusting screw 5 is rotated, thereby improving the adjustment stability of the entire device.

[0038] refer to Figure 3 and Figure 4A tightening mechanism 8 is installed on the adjusting screw 5. The tightening mechanism 8 includes an arc-shaped block 81. A rotating component 82 is installed on the arc-shaped block 81 through a fixing component 83. The rotating component 82 is connected to the adjusting screw 5. Because the top of the adjusting screw 5 covers a small area of ​​the inner wall of the template 2, when the adjusting screw 5 is rotated, the template 2 only moves partially away from the reinforcing cage 1, which makes it difficult to insert the pad. The arc-shaped block 81 increases the contact area between the adjusting screw 5 and the template 2, so that when the adjusting screw 5 is rotated, the entire end face of the template 2 moves away from the reinforcing cage 1, which facilitates the insertion of the pad and improves the efficiency of adjusting the thickness of the protective layer of the pier column.

[0039] The rotating assembly 82 includes a connecting block 821, which is mounted on the arc-shaped block 81 via a fixing assembly 83. A rotating groove 84 is formed on the end face of the connecting block 821 away from the arc-shaped block 81. A limiting groove 85 is formed on the side wall of the rotating groove 84. A slot 86 is also formed on the end face of the connecting block 821 away from the arc-shaped block 81, communicating with the limiting groove 85. A limiting block 822 is fixedly connected to the side wall of the adjusting screw 5, located at the end of the adjusting screw 5 near the template 2. The slot 822 passes through the limiting block 822 and is rotatably connected to the limiting groove 85 via the slot 86. The rotating assembly 82 also includes a first annular block 823, which is slidably connected to a first annular block 823. A plug 824 is fixedly connected to one end of the first annular block 823 near the connecting block 821. The other end of the plug 824 away from the first annular block 823 is inserted into a slot 86. The first annular block 823 near the connecting block 821 has multiple first through holes 88, and the connecting block 821 near the first annular block 823 has multiple second screw holes 87. The rotating assembly 82 also includes multiple first fixing bolts 825, which are threaded through the multiple first through holes 88 and connected to the multiple second screw holes 87.

[0040] When adjusting the thickness of the protective layer of the pier column, first place the arc-shaped block 81 between the template 2 and the reinforcing cage 1 and abut against the inner wall of the template 2. Then, insert the adjusting screw 5 into the rotating groove 84. At this time, the adjusting screw 5 drives the limiting block 822 to be inserted into the limiting groove 85. Then, the first annular block 823 abuts against the connecting block 821. At this time, the first annular block 823 drives the insert block 824 to be inserted into the slot 86. Then, the first annular block 823 is installed onto the connecting block 821 through the first fixing bolt 825. At this time, rotate the adjusting screw 5. The adjusting screw 5 drives the template 2 to move through the arc-shaped block 81, thereby realizing the adjustment of the thickness of the protective layer of the pier column.

[0041] refer to Figure 5The fixing component 83 includes a second annular block 831, which is fixedly connected to the end of the connecting block 821 away from the adjusting screw 5. The end face of the second annular block 831 away from the arc-shaped block 81 is provided with a plurality of second through holes 833. The end face of the arc-shaped block 81 near the second annular block 831 is provided with a plurality of third screw holes 811. The fixing component 83 also includes a plurality of second fixing bolts 832, which are threaded through the plurality of second through holes 833 and connected to the plurality of third screw holes 811.

[0042] The second annular block 831 and the second fixing bolt 832 enable the detachable connection between the connecting block 821 and the arc block 81, thereby facilitating the replacement of arc blocks 81 with different curvatures according to the curvature of the template 2 and improving the applicability of the entire device.
