[0002] At present, a cast-in-place concrete slab refers to building a formwork on site, installing steel bars on the formwork, then pouring concrete on the formwork, and then removing the formwork. Compared with a precast floor slab, the cast-in-place layer can enhance the integrity and seismic resistance of the house and has a relatively large bearing capacity. At the same time, it also has certain advantages in aspects such as heat insulation, sound insulation, and waterproofing.

[0003] Among them, after the cast-in-place concrete slab is transported by a transport vehicle, it will be lifted to the top of the construction project by a crane for installation. During the transportation process of the cast-in-place concrete slab, the steel bars on the side wall of the cast-in-place concrete slab will inevitably be bent, which will greatly affect the installation accuracy of the cast-in-place concrete slab.

[0004] When the market straightens the steel bars on the side wall of the cast-in-place concrete slab, most of them straighten the steel bars with a wrench. Such an operation method is not only time-consuming and laborious, but also has a low straightening efficiency. Therefore, new technical solutions need to be designed to solve this problem.

[0021] Example 1, please refer to Figures 1-3 The utility model provides a technical solution: a construction auxiliary tool for the steel bar spacing of the structural slab of a building project, including a piston cylinder 1. An inner telescopic rod 11 is movably installed inside the piston cylinder 1. The other end of the telescopic rod 11 is fixedly installed with a handle 12. A steel bar correction mechanism is installed on the piston cylinder 1;

[0022] The steel bar correction mechanism includes sliding sleeves 2 movably installed on both sides of the piston cylinder 1, a first concave - shaped frame 21 rotatably installed on the side wall of one of the sliding sleeves 2 through a first pin shaft, a folding hook 22 fixedly installed at the bottom of the first concave - shaped frame 21, and a first support seat 23 rotatably installed at one end of the piston cylinder 1 through a second pin shaft. The bottom of the folding hook 22 corresponds to the steel bar.

[0023] In this technical solution, by placing the first support seat 23 on the steel bar correction mechanism on a group of concrete pouring slabs, the operator stands on another group of concrete pouring slabs, and makes the folding hook 22 installed on the piston cylinder 1 dock with the steel bars on the concrete pouring slabs. Slowly lifting the handle 12 on the telescopic rod 11 can correct the downward - bent steel bars, making the bent steel bars in a horizontal state, thereby ensuring the spacing between the steel bars on adjacent two groups of concrete pouring slabs. This device has a simple structure and is convenient to operate.

[0024] In some technical solutions, a positioning plate 3 is fixedly installed on the side wall of the piston cylinder 1. Multiple groups of equally - spaced first positioning holes 31 are opened on the positioning plate 3. Second positioning holes 32 are opened on one side of the two sliding sleeves 2, and the two second positioning holes 32 correspond to the multiple groups of first positioning holes 31.

[0025] In this technical solution, when the first positioning hole 31 is docked with the second positioning hole 32, it can be plugged with a pin to firmly fix the sliding sleeve 2 movably installed on the piston cylinder 1, further ensuring the firmness and stability of the sliding sleeve 2 on the piston cylinder 1.

[0026] In some technical solutions, insertion holes 4 are opened at both ends of the first pin shaft, the second pin shaft, the third pin shaft, and the fourth pin shaft. An anti - detachment pin 41 is inserted into each group of insertion holes 4.

[0027] In this technical solution, when the first pin shaft, the second pin shaft, the third pin shaft and the fourth pin shaft are installed, the anti-detachment pins 41 inserted on both sides of the first pin shaft, the second pin shaft, the third pin shaft and the fourth pin shaft can prevent the first pin shaft, the second pin shaft, the third pin shaft and the fourth pin shaft from falling off after installation.

[0028] In some technical solutions, a positioning knob 13 is installed on the side wall of the piston cylinder 1 by means of threads, and the other end of the positioning knob 13 corresponds to the side wall of the telescopic rod 11.

[0029] In this technical solution, when the operator bends the steel bars of the concrete casting slab, the positioning knob 13 on the piston cylinder 1 can be screwed to adjust the length of the telescopic rod 11, and the folding hook 22 can be lifted more easily.

[0030] Example 2, refer to Figures 1-3 This is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a construction auxiliary tool for the steel bar spacing of a building engineering structural slab, which can realize the correction of the steel bars on a single casting slab. It includes a second concave frame 34 rotatably installed on the side wall of another set of sliding sleeves 2 through a third pin shaft, and a second support seat 33 rotatably installed at the bottom of the second concave frame 34 through a fourth pin shaft. Anti-slip rubber pads 24 are fixedly installed at the bottoms of the first support seat 23 and the second support seat 33.

[0031] In this technical solution, when the operator bends the steel bars on a single concrete casting slab, the second support seat 33 and the second concave frame 34 can be installed on a set of upper sliding sleeves 2 to support one end of the piston cylinder 1. The folding hook 22 installed on the other set of sliding sleeves 2 is butted against the steel bars on the concrete casting slab, and the handle 12 on the telescopic rod 11 is slowly pressed down, so that the downward-bent steel bars can be corrected to make the bent steel bars in a horizontal state.

[0032] When a construction auxiliary tool for the steel bar spacing of a building engineering structural slab is in use, it should be noted that the present utility model is a construction auxiliary tool for the steel bar spacing of a building engineering structural slab, and each component is a general standard component or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or through conventional experimental methods.

[0033] During use, when the concrete casting slab is installed on a construction project, the steel bars located outside the concrete casting slab are extremely prone to bending under collision. When the operator holds a tool to bend the steel bars on two adjacent groups of concrete casting slabs, the operator can place the first support seat 23 on the steel bar correction mechanism on one group of concrete casting slabs, stand on the other group of concrete casting slabs, and align the folding hook 22 installed on the piston cylinder 1 with the steel bar on the concrete casting slab. Slowly lifting the handle 12 on the telescopic rod 11 can straighten the downward-bent steel bar, making the bent steel bar in a horizontal state, thereby ensuring the spacing between the steel bars on two adjacent groups of concrete casting slabs. Conversely, when the operator bends the steel bars on a single concrete casting slab, the second support seat 33 and the second concave frame 34 can be installed on one set of upper sliding sleeves 2 to support one end of the piston cylinder 1. Align the folding hook 22 installed on the other set of sliding sleeves 2 with the steel bar on the concrete casting slab, and slowly press down the handle 12 on the telescopic rod 11 to straighten the downward-bent steel bar, making the bent steel bar in a horizontal state. This device has a simple structure and is convenient to operate. At the same time, through a plurality of first positioning holes 31 evenly distributed at equal intervals are formed on the positioning plate 3, and the plurality of first positioning holes 31 correspond to the second positioning holes 32 formed on one side of the two sets of sliding sleeves 2. When the first positioning hole 31 is aligned with the second positioning hole 32, they can be plugged with a pin to firmly fix the sliding sleeve 2 movably installed on the piston cylinder 1, further ensuring the firmness and stability of the sliding sleeve 2 on the piston cylinder 1.
