[0002] Before the pouring of reinforced concrete structure, the skeleton steel bar and the stirrup, the horizontal bar and other steel bars need to be installed at the construction site, and the installation interval needs to be controlled accordingly during installation. Due to the error of the predicted skeleton steel bar in the operation process, there is a problem of not being able to butt joint when the skeleton of different segments is spliced. However, since the skeleton has been shaped, when this problem occurs, two people often need to cooperate to forcibly adjust the steel bars that need to be butt jointed in the skeleton to the appropriate position. This way is difficult to operate, not easy to control, low in efficiency, and often needs the cooperation of two or more workers, wasting human resources.

[0029] Reference Figures 1-6 The present embodiment provides a calibration device for skeleton steel bar 6, which comprises a main rod 1 and two groups of clamps arranged at intervals on the main rod 1; the clamps comprise clamping grooves 4, which can be used to clamp the steel bars to be positioned; at least one group of clamps in the two groups of clamps is a movable clamp 3; the movable clamp 3 moves along the length direction of the main rod 1 to adjust the distance between the two groups of clamps; the main rod 1 comprises two groups of adjusting pieces 5, which are arranged at both ends of the movable clamp 3, and the two groups of adjusting pieces 5 can release or lock the movement of the movable clamp 3.

[0030] This calibration device, through its simple structural design, enables rapid adjustment of the spacing of precast steel reinforcement bars. It has the advantages of simple manufacturing, convenient use, precise adjustment, and wide applicability. It is suitable for the docking operations of various precast steel reinforcement cages and can significantly improve construction efficiency and quality.

[0031] Specifically, the two sets of clamps are divided into fixed clamps 2 and movable clamps 3; the fixed clamps 2 are fixed to one end of the main rod 1, and the movable clamps 3 are movably disposed at the other end of the main rod 1 (e.g., Figure 1 The movable clamp 3 includes a movable sleeve 31 (e.g., Figure 4 The movable sleeve 31 is a hollow sleeve, and a groove 4 is welded on the movable sleeve 31; the movable sleeve 31 is slidably installed on the main rod 1, and the movable sleeve 31 can slide up and down along the rod body of the main rod 1.

[0032] The adjusting component 5 is an adjusting nut 51 (e.g., Figure 3 The main rod 1 is threaded 11; the adjusting nut 51 is screwed onto the main rod 1. The main rod 1 is a threaded rod, and the main rod 1 serves as the main force-bearing rod for adjusting the spacing between the two reinforcing bars. A fixing clamp 2 with a groove 4 is welded to the top of one side of the main rod (e.g., Figure 2 Two adjusting nuts 51 are provided, respectively arranged at both ends of the movable sleeve 31.

[0033] The two sets of adjusting nuts 51 are movably arranged along the length of the main rod 1; the two sets of adjusting nuts 51 can move closer to or further apart from each other. When the two sets of adjusting nuts 51 move further apart from each other, the movable clamp 3 moves between the spacing of the two sets of adjusting nuts 51, providing adjustable space for the movable clamp 3. When the two sets of adjusting nuts 51 move closer to each other, the movable clamp 3 is fixed until it is pressed against the space between the two sets of adjusting nuts 51.

[0034] The two sets of adjusting nuts 51 are far apart from each other, and the adjusting nuts 51 at both ends limit the movable clamp 3 to prevent the movable clamp 3 from detaching from the main rod 1. When docking, the movable clamp 3 is pre-fixed at a certain distance to facilitate adjustment.

[0035] The working principle of this calibration device is as follows: when the precast skeleton steel reinforcement is 6 (e.g., Figure 5 During connection, the groove 4 of the fixing clamp 2 at one end of the main rod 1 is used to clamp one of the reinforcing bars. The upper and lower adjusting nuts 51 are adjusted so that the clamp on the movable sleeve 31 clamps the adjacent reinforcing bars (such as...). Figure 6Adjusting the adjusting nut 51 upwards can decrease the spacing between the two reinforcing bars; adjusting the adjusting nut 51 downwards can increase the spacing between the two reinforcing bars; by adjusting the nut 51 up and down, the precast skeleton reinforcing bars 6 of different segments can be smoothly spliced.

[0036] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
