Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a highly self-adjusting integrated scanning and drilling precision rebar installation device. Background Technology

[0002] Structural columns, made of reinforced concrete, are an indispensable component of masonry walls. They enhance the overall structural integrity, improve the ductility and load-bearing capacity of the masonry walls, and improve seismic performance. Reinforcing bars for structural columns can be pre-installed within the main structure or installed post-installed. If post-installation is used, installing bars at the bottom of beams or slabs requires working at height. When encountering dense reinforcement at the bottom of beams, a rebar scanner must first locate the reinforcement positions before drilling and installing bars within the gaps. Otherwise, repeated drilling may result in a "honeycomb" pattern at the bottom of the beam, causing irreversible damage to the structure.

[0003] When carrying out the work, the workers need to climb up to get close to the rebar installation location, then use a handheld rebar scanner to find the location of the rebar at the bottom of the beam before drilling can be carried out. Working at height is inherently dangerous, and this operation has many steps, which will further increase the time the operator spends at height, thus further increasing the danger of the operation.

[0004] The existing cable termination auxiliary devices have the following problems when in use;

[0005] 1. High safety risks: Currently, the reinforcement of structural columns at the bottom of beams is generally installed after the reinforcement is installed. This usually requires the setting up of scaffolding or mobile platforms, and workers have to climb to the height to operate. This method is cumbersome and has high safety risks.

[0006] 2. Low construction efficiency: Existing technologies often require multiple adjustments to the position of scaffolding and moving platforms during inspection and drilling. This necessitates workers repeatedly climbing up and down the scaffolding, wasting a significant amount of time and reducing construction efficiency. Utility Model Content

Detailed Implementation

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] See the examples. Figures 1 to 5 As shown, this utility model provides a highly self-adjusting integrated scanning and drilling precision rebar installation device, including a base 1 for supporting the entire device. The base 1 is configured as a rectangular plate, and a second fixed bracket 5 and a first fixed bracket 4 for supporting other components are fixedly connected to the upper surface of the base 1.

[0028] The outer wall of the second fixed bracket 5 is fixed with a second support plate 15 by a fourth fastening bolt 16. The second support plate 15 can support the bottom end of the second movable bracket 7. The outer wall of the second fixed bracket 5 is fixed with a second movable bracket 7 for controlling the drilling depth by a second fastening bolt 12. The outer wall of the second movable bracket 7 is provided with a second clamp 11 for further fixing the second movable bracket 7. The upper surface of the second support plate 15 is rotatably connected with a second pry bar 18 through a connecting shaft 19. By pressing the exposed part of the second pry bar 18, the right end of the second pry bar 18 can be lifted, thus pushing the second movable bracket 7 to move up and down. A drill bit 22 for drilling operations is installed on the upper surface of the second movable bracket 7.

[0029] The outer wall of the first fixed bracket 4 is fixedly connected to a first support plate 13 for supporting the bottom of the first movable bracket 6 by a third fastening bolt 14. The outer wall of the first fixed bracket 4 is connected to a first movable bracket 6 for controlling the measurement height by a first fastening bolt 10. The outer wall of the first movable bracket 6 is provided with a first clamp 9 for further locking the first movable bracket 6. The upper surface of the first support plate 13 is rotatably connected to a first pry bar 17 for driving the first movable bracket 6 to move by a connecting shaft 19. The upper surface of the first movable bracket 6 is fixedly connected to a bracket 20 for supporting the rebar scanner 21 and the marker pen 30. The rebar scanner 21 and the marker pen 30 are installed on the upper surface of the bracket 20. The detection end of the rebar scanner 21 is attached to the structural column.

A set of fixing straps 24 is respectively installed on the vertical plate 44 and the end of the bracket 20 near the drill 22 by fixing bolts 25. When installing the drill 22, the drill 22 can be placed on the top of the bracket 20 first, and then the fixing bolts 25 can be used to fix the fixing strap 24. At the same time, the fixing strap 24 needs to be wrapped around the outer wall of the drill 22. In this way, the drill 22 can be fixed. The grip part of the drill 22 and the upper surface of the bracket 20 are filled with a shock-absorbing pad 26 to reduce vibration.

[0032] Furthermore, the upper surface of the bracket 20 is also fixedly connected with a fixing strap 24 for fixing the rebar scanner 21 by fixing bolts 25. The fixing strap 24 is wrapped around the handle of the rebar scanner 21. The upper surface of the bracket 20 is equipped with an ear plate 27 for guiding the marker pen 30. The marker pen 30 is inserted into the inner wall of the ear plate 27. The marker pen 30 can move up and down on the inner wall of the ear plate 27 and can rotate around the contact point between it and the ear plate 27. The upper surface of the ear plate 27 is equipped with a clip 29 for limiting the movement trajectory of the marker pen 30. The lower surface of the marker pen 30 is equipped with a marker pen extension rod 28. By moving the marker pen extension rod 28, the marker pen 30 can be moved, thus marking the drilling position. The lower surface of the base 1 is equipped with casters 2 for supporting the movement of the entire device. The outer wall of the casters 2 is equipped with brakes 3.
