When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0023] Referring to Figures 1-4 , a device for positioning wall steel bars and controlling the cover thickness, including a sleeve 1. Both ends of the sleeve 1 are provided with telescopic grooves 4. Telescopic and adjustable positioning rods 2 are installed in the telescopic grooves 4 at both ends. The ends of the positioning rods 2 extend out of the telescopic grooves 4 and are fixedly installed with concrete seats 11. An adjustable movable lock 10 is sleeved on the positioning rods 2.

[0024] Furthermore, a screw rod 3 is strung on the positioning rod 2. Nuts 5 are rotatably connected to both ends of the sleeve 1. The nuts 5 are threadedly connected to the screw rod 3. One end of the positioning rod 2 located in the telescopic groove 4 is slidably connected to the groove wall. According to the thickness of the required protective layer, by adjusting the telescopic length of the positioning rod 2, just hold the sleeve 1 and rotate the nuts 5 at both ends. The screw rod 3 moves, and then the telescopic of the positioning rod 2 can be driven to adjust the position of the concrete seat 11.

[0025] Furthermore, a slider 8 is fixedly connected to the top of one end of the positioning rod 2 located in the telescopic groove 4. A sliding groove 7 is provided along the length direction of the top of the sleeve 1. The slider 8 is slidably connected in the sliding groove 7. Under the limiting action of the slider 8 and the sliding groove 7, the telescopic of the screw rod 3 is enabled.

[0026] Furthermore, scale lines 9 are provided on the top of the sleeve 1 at the length sides of the sliding groove 7. When the positioning rod 2 expands and contracts, the slider 8 slides in the sliding groove 7, and the telescopic distance can be accurately adjusted through the scale lines 9.

[0027] Furthermore, the movable lock 10 includes a sliding sleeve 101 sleeved on the positioning rod 2. A tightening bolt 102 is threadedly connected to the side wall of the sliding sleeve 101. A first arc-shaped clamping plate 103 is fixedly connected to the front side of the sliding sleeve 101. The two ends of the first arc-shaped clamping plate 103 are butted with a second arc-shaped clamping plate 104 through a locking bolt 105. Slide the sliding sleeve 101 to the corresponding position, lock the position by tightening the tightening bolt 102, so that a pair of vertical steel bars 15 are respectively clamped in a pair of first arc-shaped clamping plates 103, and then butt the second arc-shaped clamping plate 104 and tighten a pair of locking bolts 105 to clamp the vertical steel bars 15.

[0028] Furthermore, a T-shaped plate 12 is welded to the end of the positioning rod 2, and the concrete seat 11 wraps the T-shaped plate 12.

[0029] Furthermore, a spirit level 6 is embedded between a pair of sliding openings 7 at the top of the sleeve 1. The level is calibrated by the spirit level 6 to improve the construction quality.

[0030] The movable latch 10 can adjust its position according to the spacing between the steel bars at two rows of embedded parts. Just slide the sliding sleeve 101 to the corresponding position and lock the position by tightening the fastening bolt 102, so that a pair of vertical steel bars 15 are respectively clamped in a pair of first arc-shaped clamping plates 103.

[0031] According to the required thickness of the protective layer, adjust the telescopic length of the positioning rod 2. Just hold the sleeve 1 and rotate the nuts 5 at both ends. Under the limiting action of the slider 8 and the sliding opening 7, the screw rod 3 moves, which can drive the positioning rod 2 to telescope, adjust the position of the concrete seat 11, control the thickness of the wall steel bar protective layer, and also control the wall cross-sectional size to meet the design requirements.

[0032] When the positioning rod 2 telescopes, the slider 8 slides in the sliding opening 7. The telescopic distance can be accurately adjusted through the scale line 9, and the level is calibrated by the spirit level 6 to improve the construction quality.

[0033] Before pouring the concrete of this layer, install this device at 50 mm and 500 mm away from the floor surface of the cast-in-place wall 13 respectively. At 50 mm, the concrete seat 11 at one end of the device directly abuts against the formwork 14. After calibrating the level by the spirit level 6, according to the spacing between the two rows of vertical steel bars 15 designed in the drawing, fix the device to the vertical steel bars through the movable latch 10 in the device. Then hang it vertically and install the second device in the same way. After installation, the concrete can be poured, so as to ensure that the steel bars at the embedded part will not shift and the protective layer will also meet the design requirements.
