Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road construction technology, specifically relating to a rebar anchoring mechanism for the junction of new and old cement concrete pavements. Background Technology
[0002] In existing technologies, rebar installation at the junction of new and old concrete pavements requires workers to use hand-held impact drills or electric picks, squatting or kneeling on the roadbed to perform drilling operations, which makes it impossible to take efficient and safe construction measures.
[0003] To address the aforementioned technical problems, patent number 202321870939.4 discloses a rebar installation device for the junction of old and new concrete pavements. This patent controls the impact drill by pushing and pulling a pressure rod, thereby controlling the drilling speed and depth. The device is completely controlled without requiring workers to squat down, keeping it away from potential hazards, ensuring worker safety, and improving drilling efficiency. However, the rebar installation device in the aforementioned patent has a frame structure, which is complex and bulky. When installing rebar on-site, since the spacing between adjacent rebar installation sites is 90 centimeters, moving the rebar from one site to another requires two or three people to lift and move it, which is time-consuming, labor-intensive, and takes up a large area, making it inconvenient to carry. Summary of the Invention
[0004] The purpose of this utility model is to propose a rebar anchoring mechanism for the junction of old and new cement concrete pavements. This utility model simplifies the structure of existing rebar anchoring mechanisms through a novel structural design, making it small in size, lightweight and easy to use.
[0005] To achieve the above objectives, this utility model adopts the following technical solution:
[0006] A rebar anchoring mechanism for the junction of old and new cement concrete pavements includes two H-shaped equipment height control square steel bars connected as one unit by a track square steel bar. A movable square steel bar, capable of horizontally moving between the two equipment height control square steel bars, is fitted onto the track square steel bar. A carrying handle is hinged to the track square steel bar. The carrying handle is connected to the movable square steel bar via a hinged rod, forming a structure where the movable square steel bar moves horizontally along the track square steel bar under the action of the carrying handle. Two clips are provided on the movable square steel bar for securing an electric drill.
[0007] The two height control square steels are respectively fitted onto the corresponding fixed square steels and can move up and down along the fixed square steels to adjust the height of the rebar installation mechanism.
[0008] This utility model proposes a rebar anchoring mechanism for the junction of old and new cement concrete pavements. The entire rebar anchoring mechanism is made of square steel, has a small footprint, and a compact structure, which can be easily lifted by a single operator. It is lightweight and easy to move. When drilling, the operator controls the electric drill by holding the handle, controlling the drilling speed and depth. The control and movement of the equipment do not require the operator to squat or kneel on the ground, keeping it away from construction hazards, ensuring the safety of the operator, and improving the quality and efficiency of drilling.

[0014] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:
[0015] like Figures 1-3 As shown, a rebar anchoring mechanism is used at the junction of old and new cement concrete pavement. The rebar anchoring mechanism has two H-shaped equipment height control square steels 5. The two equipment height control square steels 5 are connected as one unit by a track square steel 6. A movable square steel 7, which can move horizontally between the two equipment height control square steels, is sleeved on the track square steel 6. A handle 1 is hinged to the track square steel 6. The handle 1 is made of square steel, and its lower end is hinged to the track square steel 6. One side of the handle is hinged to a hinge rod 2, and the other end of the hinge rod 2 is connected to a fixing plate 3 fixed on the movable square steel 7, so that the movable square steel 6 can move horizontally along the track square steel under the action of the handle 1. Two buckles 8 are provided on the movable square steel 7 for fixing an electric drill.
[0016] The fixing plate 3 is also provided with a buckle for vertically fixing the electric drill equipment.
[0017] The hinge rod 2 and the fixing plate 3 are both made of square steel.
[0018] The two height control square steels 5 are respectively fitted onto the corresponding fixed square steels 4 and can move up and down along the fixed square steels 4 to adjust the height of the rebar installation mechanism.
[0019] This equipment can be carried by a single worker along the construction route, making it lightweight and easy to move. When drilling, the worker can control the position of the electric drill by pushing or pulling the handle, and control the drilling speed and depth by controlling the position of the electric drill.
