Description

A marking device for positioning steel reinforcement in steel structure concrete floor slabs Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a marking device for positioning steel reinforcement in steel structure concrete floor slabs. Background Technology

[0002] The marking device for positioning reinforcing bars in steel-structure concrete floor slabs is suitable for use on construction sites where precise marking of the reinforcing bar positions is required before tying the reinforcing bars. This device easily marks the reinforcing bar layout lines on the floor slab formwork, ensuring that the spacing and position of the reinforcing bars meet design requirements, improving construction efficiency and the accuracy of reinforcing bar tying, thereby guaranteeing the structural safety and quality of the steel-structure concrete floor slab.

[0003] However, existing technologies still have the following problems:

[0004] Existing methods for marking and positioning rebar in floor slabs still suffer from problems such as uneven line drawing, inconsistent ink distribution, and unclear point locations. In most methods, the lack of a stable scrolling mechanism and a uniform ink distribution system causes the pen to easily jam or jump during movement, resulting in discontinuous or distorted lines. Furthermore, uneven ink distribution leads to areas being too dark or too light, affecting the legibility of the points.

[0005] To address the aforementioned problems, the inventors proposed a marking device for positioning reinforcing bars in steel structure concrete floor slabs. Summary of the Invention

[0006] To address the problems of uneven line drawing, inconsistent ink distribution, and unclear dot positions, this utility model aims to provide a line drawing device for positioning steel reinforcement in steel structure concrete floor slabs.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: As shown in Figures 1-3, this utility model provides a marking device for positioning steel reinforcement in steel structure concrete floor slabs, including a handle 1, an anti-slip sleeve 36 fixedly provided on the outer side of the handle 1, an adjustment mechanism 3 fixedly provided at the lower end of the handle 1, and a marking mechanism 2 fixedly provided at the lower end of the adjustment mechanism 3. The marking mechanism 2 includes a housing 20, one side of the housing 20 is fixedly connected to the adjustment mechanism 3, and rollers 24 are rotatably provided on both sides of the housing 20. A roller 25 is fixedly provided on one side of both rollers 24. The inner side of the roller 25... The system includes an adsorption tray 26, on the outer side of which are fixed multiple equally spaced drawing pens 27. One end of each drawing pen 27 penetrates the outer side of a roller 25. An ink inlet 23 is located on the outer side of the roller 25, and an ink filling port 21 is located on the upper surface of the outer casing 20. The inner side of the rotating cylinder 31 is threaded into a threaded rod 34. When using the drawing mechanism 2, first align the ink inlet 23 and the ink filling port 21, then inject an appropriate amount of ink into the outer casing 20 through the ink filling port 21. The ink will flow into the adsorption tray 26 inside the roller 25. Since the adsorption tray 26 is a sponge tray, it can adsorb and evenly distribute the ink. Next, the drawing mechanism 2 is placed above the floor slab where lines need to be drawn. The rollers 24 rotating on both sides of the outer casing 20 ensure smooth rotation of the roller 25. As the roller 25 rotates, the multiple equally spaced drawing pens 27 fixed on its outer side will rotate accordingly, evenly drawing clear dots on the floor slab during the rolling process. If ink needs to be replenished, it can be added again through the ink filling port 21.

[0018] The adjustment mechanism 3 includes an adjustment cylinder 30, the upper end of which is fixedly connected to the lower end of the handle 1. A threaded rod 34 is slidably provided on the inner side of the adjustment cylinder 30. A limiting block 35 is fixedly provided on the upper end of the threaded rod 34, and the limiting block 35 is slidably fitted against the outer side of the adjustment cylinder 30. A connecting base 33 is fixedly provided on the lower end of the threaded rod 34, and one end of the connecting base 33 is fixedly connected to one side of the outer casing 20. A rotating cylinder 31 is rotatably provided on the lower end of the adjustment cylinder 30. When using the adjustment mechanism 3, first hold the handle 1, and rotate the rotating cylinder 31 to drive the threaded rod 34 at the lower end of the adjustment cylinder 30 to slide inside the adjustment cylinder 30. The limiting block 35 is fixedly provided on the upper end of the threaded rod 34, and the limiting block 35 is slidably fitted against the outer side of the adjustment cylinder 30 to ensure that the threaded rod 34 remains stable during the sliding process. A connecting base 33 is fixedly provided at the lower end of the threaded rod 34. One end of the connecting base 33 is fixedly connected to one side of the outer casing 20. Therefore, the sliding of the threaded rod 34 will cause the drawing line mechanism 2 to rise or fall as a whole, thereby realizing the adjustment of the drawing line height. After adjusting to a suitable height, the drawing line operation can be performed.

[0019] Both sides of the outer casing 20 are fixedly equipped with baffles 28. The inner side of the baffles 28 slides against the rollers 24, preventing the rollers 24 from shifting or shaking during rotation, thus improving the stability and drawing accuracy of the drawing mechanism 2. The upper end of the ink inlet 21 is fitted with a cover plate 22, which prevents ink from overflowing or evaporating when not needed, keeping the ink clean and effective. The suction tray 26 is a sponge tray that can absorb and evenly distribute ink, ensuring a uniform ink supply to the drawing pen 27 during the drawing process, thus improving the drawing quality.

[0020] Multiple annularly distributed anti-slip grooves 32 are provided on the outer side of the rotating cylinder 31, which can increase the friction of the rotating cylinder 31 during rotation, prevent slippage or uneven rotation, and improve the ease of use and adjustment accuracy of the adjustment mechanism 3. A limiting groove 37 is provided on the outer side of the adjustment cylinder 30. The inner side of the limiting groove 37 slides and fits against the limiting block 35, which can further limit the sliding range of the threaded rod 34, prevent over-adjustment or damage to the mechanism, and improve the reliability and safety of the adjustment mechanism 3.

[0021] Working principle: When using the line drawing mechanism 2, first align the ink inlet 23 and ink filling port 21, then inject an appropriate amount of ink into the outer casing 20 through the ink filling port 21. The ink will flow into the suction plate 26 inside the roller 25. Since the suction plate 26 is a sponge plate, it can absorb and evenly distribute the ink. Next, place the line drawing mechanism 2 above the floor where the line needs to be drawn, and ensure the smooth rotation of the roller 25 by the rotating rollers 24 on both sides of the outer casing 20. When the roller 25 rotates, the multiple equally spaced line drawing pens 27 fixed on its outer side will rotate accordingly, and draw clear dots evenly on the floor during the rolling process. If ink needs to be replenished, it can be added again through the ink filling port 21.

[0022] When using the adjustment mechanism 3, first hold the handle 1 and rotate the rotating cylinder 31 to drive the threaded rod 34 at the lower end of the adjustment cylinder 30 to slide inside the adjustment cylinder 30. A limiting block 35 is fixedly provided at the upper end of the threaded rod 34, and the limiting block 35 slides and fits against the outer side of the adjustment cylinder 30 to ensure the threaded rod 34 remains stable during sliding. A connecting base 33 is fixedly provided at the lower end of the threaded rod 34, and one end of the connecting base 33 is fixedly connected to one side of the outer casing 20. Therefore, the sliding of the threaded rod 34 will cause the drawing line mechanism 2 to rise or fall as a whole, thereby adjusting the drawing height. After adjusting to a suitable height, the drawing operation can be performed.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
