[0002] In structures such as building buildings and subway stations, walls are generally reinforced with double rows of bidirectional steel bars on both sides, with the main bars being vertical steel bars. During construction, the spacing between the main steel bars, the row spacing between the two rows of main steel bars, and the thickness of the concrete cover are easily affected by the skill level of the workers and subsequent concrete pouring processes, leading to deviations and affecting the quality of wall construction. Controlling the row spacing and the thickness of the concrete cover is a key aspect to ensure the quality of the wall structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 4This utility model provides a technical solution: an auxiliary control device for the spacing and protective layer of wall reinforcement bars, including a concrete pouring surface 1 and two side wall formwork 2. Multiple sets of main side wall reinforcement bars 3 are arranged on both sides of the concrete pouring surface 1. Single-sided slotted angle steel 4 is tied to the surface of the main side wall reinforcement bars 3 with wire. A spacing control beam assembly 5 is arranged between the two main side wall reinforcement bars 3. A square tube 6 for controlling the protective layer thickness is arranged on the outer side of the main side wall reinforcement bars 3. Through the combination of the single-sided slotted angle steel 4, square tube 6, slot 7, and spacing control beam assembly 5, the spacing of the main reinforcement bars, the spacing of the reinforcement bars, and the thickness of the protective layer are effectively controlled sequentially during construction. This reduces and eliminates deviations in the spacing and protective layer caused by poor worker skill levels, concrete pouring, and vibration, thereby improving the pass rate of the wall's reinforcement spacing and protective layer, and ultimately improving the overall construction quality of the project. The row spacing control beam assembly 5 includes a first beam 501 and a second beam 502 mounted on the main reinforcement bars 3 of the side wall. One end of the first beam 501 has an adjustment groove 503, into which an adjustment beam 504 is inserted. A fixing hole is provided on the outer side of the first beam 501, through which an adjustment fixing post 505 passes. A beam support leg 506 is welded to one side of both the first beam 501 and the second beam 502. Through the arrangement of the row spacing control beam assembly 5, it is possible to adjust the spacing according to different wall structures. The purpose of the reinforcement design requirement is to quickly adjust the spacing to control the length of the crossbeam assembly 5. During use, the two limit caps 10 of the adjusting fixing column 505 are unscrewed, allowing the adjusting beam 504 on the second crossbeam 502 to move inside the adjusting groove 503 of the first crossbeam 501. The corresponding adjusting hole 8 is quickly selected according to the measuring line 11, and then the adjusting fixing column 505 is inserted into it and fixed with the limit caps 10. Thus, in different wall reinforcement design requirements, it is not necessary to replace the entire crossbeam, which helps to improve the versatility of the device.

[0020] The outer side of the single-sided slotted angle steel 4 has several slots 7 with the same spacing as the main reinforcement bars 3 of the side wall. These slots are used to control the distance between two adjacent main reinforcement bars 3 of the side wall. The slots 7 are used to accurately position and fix the spacing of the main reinforcement bars 3 of the side wall, preventing the reinforcement bars from shifting during the binding or pouring process.

[0021] The surface of the adjusting beam 504 is provided with several adjusting holes 8, which are adapted to the adjusting fixing column 505. The cooperation between the adjusting holes 8 and the adjusting fixing column 505 facilitates the adjustment and locking of the row spacing to control the length of the crossbeam assembly 5, thus adapting to the construction needs of different wall thicknesses.

[0022] The surface of the adjusting fixing column 505 is perforated with a shim 9, and one end of the surface of the adjusting fixing column 505 is threaded with two limit caps 10. The shim 9 and the limit caps 10 enhance the connection stability and prevent the adjusting fixing column 505 from loosening, ensuring that the row spacing control beam remains fixed during use.

[0023] The crossbeam support leg 506 is made of diameter steel bar. One side of the crossbeam support leg 506 is attached to one side of the single-sided slotted angle steel 4. The crossbeam support leg 506 plays the role of supporting and positioning the row spacing control crossbeam assembly 5, so that it is stably erected between the single-sided slotted angle steel 4 on both sides.

[0024] A measuring line 11 is provided above the surface of the adjusting beam 504. The spacing of the measuring line 11 is consistent with that of the adjusting hole 8. The measuring line 11 helps to quickly locate the position of the adjusting hole 8, making it convenient for construction personnel to make intuitive and accurate length adjustments.

[0025] The first crossbeam 501 and the second crossbeam 502 are installed perpendicular to the wall direction on two single-sided slotted angle steels 4 and fixed with tie wire. The installation method perpendicular to the wall direction effectively controls the spacing between the two rows of side wall main reinforcement bars 3, ensuring that the reinforcement arrangement meets the design requirements.

[0026] The square tube 6 is fixed above the single-sided slotted angle steel 4 by binding wire, so that the distance between the main reinforcement 3 of the side wall and the side wall formwork 2 is consistent. The setting of the square tube 6 plays a role in uniformly controlling the thickness of the reinforcement protective layer, preventing the reinforcement from sticking to the formwork or the protective layer thickness from being uneven during concrete pouring.

[0027] In this invention, the working steps of the device are as follows: First step: When binding the reinforcing bars on site, to control the spacing of the main reinforcing bars, customize the single-sided slotted angle steel 4 according to the diameter and spacing of the single-sided slotted angle steel 4. The spacing of the slots 7 of the single-sided slotted angle steel 4 is the same as the spacing of the main reinforcing bars 3 of the side wall. Insert the main reinforcing bars 3 of the side wall into the slots 7 of the single-sided slotted angle steel 4 one by one. Use the slotted structure to control the spacing of the main reinforcing bars 3 of the side wall. Then, use tie wire to bind and fix the single-sided slotted angle steel 4 and the main reinforcing bars 3 of the side wall. After the spacing of the main reinforcing bars 3 of the side wall is controlled, control the spacing of the reinforcing bar rows. The second step: When using it, according to the different wall reinforcement design requirements, unscrew the two limit caps 10 of the adjusting fixing column 505, so that the adjusting beam 504 on the second beam 502 moves inside the adjusting groove 503 of the first beam 501. Quickly select the corresponding adjusting hole 8 according to the measuring line 11, then insert the adjusting fixing column 505 into it, and then fix it with the limit cap 10. Adjust the row spacing to control the length of the beam.

[0028] The third step: The spacing control beam assembly 5, with welded beam support legs 506, is placed perpendicular to the wall between two single-sided slotted angle steels 4. The beams are installed every two meters and fixed with tie wire to control the spacing of the reinforcing bars. Finally, according to the thickness of the protective layer, the square tube 6 is fixed above the single-sided slotted angle steel 4 with tie wire to make the distance between the main reinforcement 3 of the side wall and the side wall formwork 2 uniform and consistent, thereby controlling the thickness of the protective layer.
