Due to certain errors in manual operation, the spacing of the main steel bars is often uneven and the positioning is inaccurate, which causes certain difficulties in the connection of the steel reinforcement cages made in sections, seriously affecting the overall quality of the steel reinforcement cage and the construction operation of the subsequent concrete pouring. Content of the Utility Model

A plurality of steel bar clamps are provided and detachably fixed on the outer circumference of the semi-circular framework.

[0006] Further, the steel bar clamp comprises two slats with U-shaped notches at the ends and a bolt and nut connecting piece connected between the slats. The two slats are clamped on the annular positioning framework.

[0007] Further, the U-shaped elastic clamp comprises a U-shaped rod and an L-shaped rod. One end of the L-shaped rod is connected to one end of the U-shaped rod and is perpendicular to the U-shaped rod. The U-shaped rod clamps the straight rod sections of the two semi-circular frameworks, and the other end of the L-shaped rod horizontally penetrates through the straight rod sections of the two semi-circular frameworks.

[0008] Further, two U-shaped elastic clamps are arranged at intervals along the length direction of the straight rod section of the annular positioning framework.

[0009] The utility model has the following beneficial effects:

[0010] 1.

[0011] 2. The components of the utility model are delicate, facilitating production and carrying. After the device is installed, only the two semi-circular frames need to be installed and removed through the U-shaped elastic fixture. Subsequently, it is not necessary to re-measure and arrange the positions of the main reinforcement bars of the steel reinforcement cage, and the device can be adjusted according to the actual construction site requirements, greatly improving the work efficiency.

[0017] The following will be a detailed description of the present utility model in conjunction with the drawings and specific embodiments.

[0018] Refer to Figures 1 - 4 , the prefabricated steel reinforcement cage positioning device of this embodiment includes an annular positioning skeleton 1 and a steel bar fixture 2. The annular positioning skeleton 1 includes two semi-circular frames and a U-shaped elastic fixture 3 detachably connected between the two semi-circular frames. After the two semi-circular frames are assembled, they form a circular ring. A plurality of steel bar fixtures 2 are provided and detachably fixed on the outer circumference of the semi-circular frame. According to the requirements of the engineering construction, after determining the number and spacing of the main reinforcement bars, the steel bar fixture 2 can be installed on the annular positioning skeleton 1 to achieve the positioning and fixing of the main reinforcement bars.

[0019] The steel bar fixture 2 includes two strip plates with U-shaped notches at the ends and a bolt and nut connecting member connected between the strip plates. The two strip plates are clamped on the annular positioning skeleton 1 for fixing the steel bar fixture 2 to the annular positioning skeleton 1.

[0020] The U-shaped elastic fixture 3 includes a U-shaped rod and an L-shaped rod made of spring steel. One end of the L-shaped rod is connected to one end of the U-shaped rod and is perpendicular to the U-shaped rod. The U-shaped rod clamps the straight rod segments of two semi-circular frames, and the other end of the L-shaped rod horizontally penetrates the straight rod segments of the two semi-circular frames; Two U-shaped elastic fixtures 3 are arranged at intervals along the length direction of the straight rod segment of the annular positioning framework 1. By inserting the semi-circular frames and buckling the straight rod segments of the semi-circular frames, the splicing and fixing of the annular positioning framework 1 can be realized to carry the reinforcing ribs, which is convenient for the positioning and welding of the main bars of the steel reinforcement cage.

[0022] When it is necessary to fabricate a steel reinforcement cage, the positioning annular positioning framework 1 is processed and fabricated according to the designed diameter of the steel reinforcement cage. The positioning annular framework 1 is composed of two semi-circular frames, and the two semi-circular frames are connected by two U-shaped elastic fixtures 3 arranged at intervals along the length direction of the straight rod segments of the semi-circular frames. Insert the L-shaped rod part of the U-shaped elastic fixture 3 into the framework connection hole, and rotate the U-shaped elastic fixture 3 so that the U-shaped part is clamped on the annular positioning framework 1, so that the two semi-circular frames are connected to form the annular positioning framework 1. According to the designed spacing of the main bars of the steel reinforcement cage, the steel bar fixtures 2 are connected by bolt and nut connectors to thread-connect the upper and lower slats of the steel bar fixtures 2, and the steel bar fixtures 2 are evenly fixed on the outer circumference of the annular positioning framework 1. The steel bar fixtures 2 can be finely adjusted by the bolt and nut connectors so that the required positions of the steel bar fixtures 2 can be evenly distributed on the same circumference before being fixed. When fabricating the steel reinforcement cage, place the main bars in the card slots of the steel bar fixtures 2. After welding and fixing the main bars and the reinforcing ribs of the steel reinforcement cage one by one, remove the U-shaped elastic fixture 3 to separate the two semi-circular frames to end the fabrication of the steel reinforcement cage; When it is necessary to connect the steel reinforcement cage in segments, place the device at the joint part of the steel reinforcement cage, place each main bar in the steel bar fixture 2, ensure the consistency of the connection joint spacing of the main bars at both ends of the steel reinforcement cage, which is convenient for the joint welding of the steel reinforcement cage, significantly improves the construction efficiency and construction quality of the steel reinforcement cage, and the device can be adjusted according to the actual construction site requirements, which is beneficial to improving the engineering efficiency.
