Technical Field

[0001] This invention relates to the field of rebar drilling technology, specifically to an auxiliary support tool for rebar drilling in secondary structures. Background Technology

[0002] During the secondary structural construction of a building, it is necessary to install rebar holes in the floor slabs and top slabs, and to drill holes in the walls or columns at certain intervals and insert tie bars to increase the integrity and stability of the walls and ensure the quality of the construction project.

[0003] During the current construction process, when the secondary structure construction begins, the floor formwork support frame has been removed. When drilling holes, it is necessary to re-erect movable scaffolding. The scaffolding is moved to the location where the hole needs to be drilled, and workers climb the scaffolding to carry out the drilling operation. The scaffolding erection process is quite cumbersome and difficult to move. At the same time, construction workers need to frequently go up and down the scaffolding, which increases the workload of the workers. In addition, working at height will also increase the safety risks for the workers. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary support tool for drilling and anchoring rebar in secondary structures, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary support tool for drilling holes for rebar installation in a secondary structure, comprising a threaded support column, with pads fixedly connected to both sides of the threaded support column, a limiting groove provided at the side end of the threaded support column, an adjusting sleeve provided in the middle of the threaded support column, a driving ring provided at the lower end of the adjusting sleeve, multiple limiting plates snapped onto the side end of the driving ring, the driving ring and the threaded support column being threadedly connected, a support plate fixedly connected to the side end of the adjusting sleeve, a reinforcing rib fixedly connected to the side end of the adjusting sleeve, the top end of the reinforcing rib fixedly connected to the support plate, a slide rail column provided at the top end of the support plate, guide grooves provided on both sides of the slide rail column, a fixed seat provided at the upper end of the slide rail column, both ends of the fixed seat being slidably connected to the guide grooves, an electric drill fixedly connected to the middle of the fixed seat, a control plate fixedly connected to the lower end of the fixed seat, a displacement control mechanism fixedly connected to the lower end of the control plate, and a pressing drive mechanism provided at the lower end of the slide rail column, the pressing drive mechanism abutting against the lower end of the displacement control mechanism.

The upper end of the limiting plate 15 is engaged with the auxiliary ring. A limiting block 16 is fixedly connected to the inner wall of the adjusting sleeve 3. The limiting block 16 is slidably connected in the limiting groove 13. The limiting plate 15 connects the adjusting sleeve 3 and the drive ring 14. By rotating the drive ring 14, the drive ring 14 moves upward and drives the adjusting sleeve 3 to move together. The limiting groove 13 restricts the limiting block 16, so that the adjusting sleeve 3 can only move vertically to adjust the height of the electric drill 8.

[0022] The displacement control mechanism 17 consists of a fixed ring 171, a fixed plate 172, a reset ring 173, a reset spring 174, and a guide member 175. The fixed ring 171 is fixedly connected to the slide rail column 5, and the reset ring 173 is sleeved on the slide rail column 5. The reset ring 173 is located at the lower end of the fixed ring 171. The fixed plates 172 are arranged in a ring at the lower end of the fixed ring 171. The reset ring 173 and the fixed plate 172 are slidably connected.

Both the mounting part 12 and the snap-fit ​​groove 11 are T-shaped structures. The mounting part 12 is snapped into the snap-fit ​​groove 11, and then the mounting part 12 and the support plate 4 are fixed with bolts. This can connect the slide rail column 5 and the threaded support column 1 into a whole, which is convenient for installation and disassembly, for moving the device, and for adjusting the direction of the slide rail column 5, thereby drilling holes in the floor and ceiling.

[0025] The mounting 12 is snapped into the snap-fit ​​groove 11. The electric drill 8 is adjusted according to the drilling position. The slide rail column 5 and the threaded support column 1 are spliced ​​and installed. After the threaded support column 1 is installed and fixed, the handle 183 is turned. The connecting protrusion 184 at the upper end of the handle 183 squeezes the reset ring 173, thereby compressing and storing the reset spring 174. The electric drill 8 performs preliminary drilling. Then, the handle 183 and the control ring 181 are rotated along the auxiliary protrusion 19, so that the connecting protrusion 184 moves along the guide member 175. Guided by the guide member 175, the height of the electric drill 8 is adjusted to control the drilling depth.
