Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for building construction, and in particular to a device for quickly marking the spacing of steel bars in a top slab. Background Technology

[0002] During building construction, the accurate spacing of the top slab reinforcement is crucial to the quality and performance of the concrete structure. Traditional manual marking and positioning methods are inefficient and prone to errors, especially when constructing large-area top slabs, where it is difficult to guarantee the accuracy and speed of marking, thus affecting the progress and quality of subsequent reinforcement binding and concrete pouring. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a device for quickly marking the spacing of the top slab reinforcement bars, so as to solve the problems pointed out in the background art.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A device for quickly marking the spacing of reinforcing bars in a roof slab includes a mounting plate. A push rod is mounted on one side of the mounting plate, and a mounting shaft is fixed to the center of the other side. A rotating plate is rotatably mounted on the mounting shaft. An annular tube filled with ink is fixedly mounted on the rotating plate via a fixing assembly. The annular tube is transparent, allowing the operator to visually observe the remaining ink level and replenish it promptly, preventing marking interruptions. The annular tube has a filling port with a filling cap. Multiple outlet tubes are evenly spaced around the annular tube. A rigid cylindrical sponge is attached to the outlet end of each outlet tube, and a cap is threaded onto the outlet end. The caps at the outlet ends are tightened when not in use to prevent the sponge from drying out or accidentally leaking ink, maintaining sponge moisture and keeping the device clean.

[0005] As a further improvement of this utility model, a threaded sleeve is fixed on one side of the mounting plate, one end of the push rod is threaded into the threaded sleeve, and the other end is fixed with a handle.

[0006] As a further improvement of this utility model, a washer and a mounting nut are sequentially provided on both sides of the rotating plate on the mounting shaft, and the rotating plate is rotated and fixed on the mounting shaft by the two mounting nuts on both sides of the rotating plate.

[0007] As a further improvement of this utility model, the fixing assembly includes two arc-shaped clamping plates symmetrically arranged inside the annular tube. A fastening screw is fixed on the rotating plate, and the fastening screw passes through the mounting hole on the arc-shaped clamping plate and is threaded to a fastening nut. A pressure plate for pressing the annular tube is symmetrically arranged on the side of the arc-shaped clamping plate near the annular tube. The fixing assembly can firmly clamp the annular tube onto the rotating plate, preventing loosening and displacement during operation. The rubber pad increases friction and prevents the pressure plate from directly contacting the hard annular tube and causing damage. Loosening the fastening nut allows for quick disassembly and replacement of the annular tube or addition of ink, making maintenance convenient.

[0008] As a further improvement of this utility model, a rubber pad is fixed on the side of the pressure plate that contacts the annular tube.

[0009] As a further improvement of this utility model, the annular tube is provided with six liquid outlet pipes at equal intervals along its circumference.

[0010] As a further improvement of this utility model, a sealing gasket is fixed to the inner side of the filling cap. The filling port is equipped with a filling cap with an inner sealing gasket, which effectively prevents ink leakage or evaporation when not being added, reducing environmental pollution and waste.

[0011] The beneficial effects of this utility model are as follows: By integrating multi-point ink output through an annular tube, hard sponge printing dots, adjustable push rod, rotatable installation, and convenient fixing and sealing structure, this utility model achieves high efficiency, accuracy, clarity, and convenience in rebar spacing marking operations, significantly improving construction quality and efficiency, reducing labor costs and error risks, and has high practical value.
