Description

Technical Field

[0001] This invention relates to the field of building construction, and more specifically to an auxiliary device for anchoring rebar in structural columns in building engineering. Background Technology

[0002] In building construction, structural columns are key components that enhance the seismic performance of masonry structures and frame infill walls. Rebar anchoring technology is an important means of ensuring a reliable connection between structural columns and the main structure (such as beams, slabs, and walls). Through rebar anchoring, structural columns form a rigid connection with the main structure, effectively restraining cracking and deformation of masonry walls and improving the overall integrity of the building. Under earthquakes or wind loads, anchored structural columns can work together to prevent wall collapse and improve the building's seismic resistance. Rebar anchoring technology for structural columns is a crucial process for ensuring building structural safety, improving seismic performance, and adapting to modern construction needs. Its core value lies in reliable connection, precise construction, and high efficiency and economy, having a profound impact on the quality and durability of building projects.

[0003] However, in actual construction, there are many problems with rebar installation in structural columns, especially in the upper part of the structural column. Due to the influence of working at height, the quality of construction depends entirely on the technical level and experience of the operators, resulting in unstable hole quality, reduced construction efficiency, and significant safety hazards associated with working at height. This does not meet the current industry requirements for refined, standardized, and tool-based construction. Summary of the Invention

[0004] To address the problems of slow construction efficiency, unstable quality, and poor safety in traditional structural column rebar installation techniques, this invention provides an auxiliary device for structural column rebar installation that simultaneously meets multiple functions, including high efficiency of tool-type hole forming; high quality of precise and stable hole forming; multi-functionality of simultaneous hole cleaning; and high safety of ground operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structural column rebar anchoring auxiliary device is characterized by comprising a support device, a rotating device, a drilling device, and a hole cleaning device; the support device is connected to the rotating device and can be adjusted by turning; the drilling device and the hole cleaning device are installed on the turntable in the rotating device to achieve the dual functions of drilling and hole cleaning.

[0007] The support device includes a circular top support, a top support screw, a column, a bottom support screwdriver, a bottom support screw, and a square bottom support, all made of steel.

[0008] The column is equipped with a top support screw and a bottom support screw at its upper and lower ends, respectively. The top support screw, the bottom support screw and the column are integrated as one piece. A round top support is welded to the upper part of the top support screw. A square bottom support is welded to the lower part of the bottom support screw. The height can be adjusted by turning the thread of the bottom support screw with a bottom support screw tightener.

[0009] The rotating device includes a turntable with a drilling guide tube and a cleaning guide tube mounted on it. A threaded hole is provided at the center of the turntable's axis. The turntable is fixed and adjusted by screwing the top support screw in the support device through the threaded hole, thereby adjusting the height of the rotating device. At the same time, the rotating device adjusts the position of the drilling guide tube and the cleaning guide tube by rotating, achieving high efficiency in constructing all rebar holes of the same structural column with a single fixation of the device.

[0010] The drilling device includes a drilling device, a jacking device, a fixed frame, a sliding groove, a pressure rod hole, a cable groove, and a cable, wherein the fixed frame, sliding groove, drill rod, jacking rod, pressure rod, and connecting pin are all made of steel.

[0011] The drill rod is inserted into the drilling guide tube in the rotating device; the fixed frame is bolted to the turntable to achieve synchronous rotation with the rotating device; the fixed frame is equipped with a sliding groove to realize the up and down sliding of the drilling device; the fixed frame is equipped with a cable groove and a pressure rod hole on both sides respectively. The cable groove is used to connect the external power supply of the drilling device cable, and the pressure rod hole is used for the pressure rod to push the drilling device.

[0012] The drilling device includes a drill rod, a motor, a switch, and a power cord. The drill rod passes through the upper drilling guide tube to achieve the guiding function of drilling positioning. The lower part of the drilling device is connected to a jacking device.

[0013] The drill pipe is connected to the motor, the motor is connected to the switch, and the switch is connected to the power cord.

[0014] The jacking device includes a jacking rod, a jacking rod connecting hole, a pressure rod, and a connecting pin. The upper end of the jacking rod is connected to the motor in the drilling device, and the lower end of the jacking rod is connected to the pressure rod through the jacking rod connecting hole and the connecting pin. The pressure rod passes through the pressure rod hole to push the drilling device upward to achieve drilling, ensuring the convenience and safety of ground drilling. The jacking rod is equipped with multiple jacking rod connecting holes and pressure rod holes. By adjusting the position of the pressure rod connecting to the jacking rod and the position of the pressure rod passing through the pressure rod hole, the practicality of drilling operations on structures of different heights can be met.

[0015] The hole cleaning device includes a jet nozzle, a duct, a fixing rod, fixing clips, and a control valve. The upper part of the duct is connected to the jet nozzle to clean the rebar holes with gas, and the lower part of the duct is connected to an air compressor to supply gas. A control valve is installed at the end of the duct connected to the air compressor. The upper part of the duct passes through a hole cleaning guide tube of the rotating device to guide the jet nozzle for hole cleaning. The upper part of the fixing rod is bolted to a turntable to achieve synchronous rotation with the rotating device. Fixing clips are evenly distributed on the fixing rod to secure the duct.

[0016] This invention solves many shortcomings and problems of traditional rebar drilling for structural columns, such as unstable drilling quality, incomplete hole cleaning, low construction efficiency, and significant safety hazards. First, the rotating device achieves high efficiency by fixing the device once and drilling all rebar holes in the same structural column at once. Second, the stabilizing and guiding functions of this tool-type rebar drilling auxiliary device achieve high-quality, precise, and stable hole formation. Third, the hole cleaning device enables simultaneous hole cleaning and multi-functionality. Fourth, the inclusion of a jacking device in the drilling apparatus solves the extreme safety risks of high-altitude drilling operations, achieving high safety for ground-based operations.
