A traction device for vibrating concrete on steep slopes

Abstract

This application discloses a traction device for vibrating concrete on steep slopes in the field of concrete pouring technology. It includes a vibrator and a steel wire embedded in the reinforcing cage of the slope. A hexagonal nut is connected to the vibrator 10-15 cm from its bottom. Both ends of the steel wire are connected to the main reinforcing bars at the top and bottom of the slope, respectively, and pass through the nut to form a traction structure, guiding the vibrator to vibrate along the slope. This device, through the mechanical constraint of the steel wire and the nut, solves the problem of insufficient vibration caused by the vibrator falling vertically due to gravity when vibrating concrete on steep slopes. It allows the vibrator to move directionally along the slope, ensuring uniform and dense concrete compaction, effectively avoiding quality defects such as honeycomb and pitting, improving construction quality and reducing rework costs. It is suitable for the construction of steep slope concrete components such as chimney foundations and cooling tower A-frame columns.

Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, specifically to a traction device for vibrating concrete on steep slopes. Background Technology

[0002] In thermal power projects, the construction of steeply sloping concrete components (such as chimney foundation bases and cooling tower A-frame columns) presents significant challenges: Traditional vibration methods cause vibrators to fall vertically due to gravity, preventing sufficient compaction along the slope and resulting in quality issues like honeycombing, surface defects, and root defects. Current technologies lack specialized structures for sloping surface vibration, making it difficult to guarantee construction quality and leading to high rework costs. Utility Model Content

[0003] The present invention aims to provide a traction device for vibrating concrete on steep slopes, in order to solve the technical problem that the vibrator falls vertically due to gravity and cannot fully vibrate along the slope direction, resulting in quality defects such as honeycomb and pitted surface in the concrete.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a traction device for vibrating concrete on a steep slope, comprising:

[0005] The vibrator has a traction component connected to it 10-15cm from the bottom.

[0006] The steel wires are embedded in the inclined steel cage, and the two ends of the steel wires are connected to the main reinforcement bars at the top and bottom of the inclined plane, respectively. The spacing between adjacent steel wires is 500-800mm.

[0007] The steel wire is inserted into the traction component of the vibrator to form a traction structure, guiding the vibrator to vibrate along the inclined plane.

[0008] The working principle of this invention is as follows: A hexagonal nut is welded to the front end of the vibrator and a steel wire pre-embedded in the inclined steel cage is inserted to form a directional traction track. During concrete pouring, the vibrator moves along the steel wire track, forcibly maintaining an angle of ≤10° with the inclined plane. By adjusting the spacing and tension of the steel wires, the vibration path and depth are precisely controlled, transforming traditional free vibration into directional vibration. This effectively solves the problem of vibrator displacement caused by gravity in steep inclined concrete, achieving a uniform and dense vibration effect.

[0009] The beneficial effects of this invention are as follows: By setting a traction component at a specific position on the vibrator and combining it with a pre-embedded steel wire to form a traction structure, the vibrator can be forcibly guided to vibrate along the inclined plane, effectively avoiding the problem of the vibrator falling vertically due to gravity in traditional vibration, significantly improving the density of concrete, and avoiding quality defects such as honeycomb and pitting. This structure enables precise control of the vibration path, covers the effective vibration range of the vibrator, reduces missed vibration, and at the same time reduces rework costs and improves construction efficiency by achieving the standard in one pour.

[0010] Furthermore, the traction component is a hexagonal nut. Confining the traction component to a hexagonal nut utilizes its standard structure to form a stable connection with the steel wire, preventing jamming or detachment. The hexagonal outer wall also facilitates adjustment of the vibration angle by construction personnel, enhancing operational convenience. The nut uses common hardware, resulting in low cost, simple welding process, and mass production, thus reducing equipment costs.

[0011] Furthermore, the top of the steel wire is equipped with a detachable buckle, and the bottom of the steel wire is tied and fixed to the reinforcing cage by a hook. The detachable buckle at the top and the hook at the bottom allow for flexible adjustment of the steel wire tension, preventing it from being too loose or too tight and affecting the vibration effect. The hook at the bottom is used to fix the steel wire to the reinforcing cage, ensuring that it does not shift during construction, improving the reliability of the fixation, and reducing the risk of vibration failure.

[0012] Furthermore, the steel wire is parallel to the inclined reinforcing cage. This parallel alignment ensures the traction direction matches the slope, guaranteeing the vibrator operates in a suitable direction, resulting in uniform concrete aggregate distribution, adaptability to steep slopes, and avoidance of vibration dead zones.

[0013] Furthermore, there is a certain distance between the steel wire and the inclined reinforcing cage. Maintaining a certain distance between the steel wire and the reinforcing cage avoids direct contact between the steel wire and the reinforcing bars, preventing vibration transmission, providing space for the vibrator to move, preventing scratching of the anti-corrosion layer of the reinforcing bars, reducing the loss of vibration energy by the reinforcing bars, and improving vibration efficiency.

[0014] Furthermore, a rubber damping block with a thickness of 20-30mm is connected to the bottom of the steel wire. This rubber damping block absorbs the vibration reaction force, reduces the energy transmitted to the reinforcing cage, protects the stability of the connection between the reinforcing steel and the formwork, reduces construction noise, meets environmental protection requirements, and avoids related rectification costs.

[0018] The following detailed description illustrates the specific implementation method:

[0019] The basic implementation examples are as follows: Figure 1 - Appendix Figure 2 As shown: A traction device for vibrating concrete on a steep slope includes a vibrator 2, a steel wire 3, and a hexagonal nut 4. The vibrator 2 is a 50mm diameter model, and an M12 hexagonal nut 4 is welded 12cm from its bottom. The hexagonal nut 4 is made of 304 stainless steel, and its inner diameter is compatible with the 12mm diameter pre-embedded steel wire 3. A working frame 1 is set at the top of the reinforcing cage. The steel wire 3 is made of D12Q235B carbon steel and is arranged parallel to the inclined reinforcing cage. There is a certain distance between the steel wire 3 and the inclined reinforcing cage. The reinforcing cage is vertically set by horizontal bars 5 and vertical bars 6. The top of the steel wire 3 is fixedly connected to the top horizontal bar 5 or vertical bar 6 by a detachable buckle, and the bottom of the steel wire 3 is fixed to the bottom horizontal bar 5 or vertical bar 6 by a hook binding method. The spacing between adjacent steel wires 3 is 750mm.

[0020] The specific implementation process is as follows: During construction, steel wires 3 are pre-embedded at intervals during the steel cage binding stage. The bottom hooks are firmly tied to the main reinforcement of the ring base, and the top clips are not fixed for the time being. When the concrete is poured to the slope, the nut of the vibrator 2 is inserted into the steel wire 3 on the work frame 1. The clips are adjusted to make the tension of the steel wire 3 moderate. The vibrator 2 is started to vibrate along the traction direction of the steel wire 3. The insertion depth is controlled at 2 / 3 of the thickness of the concrete layer. Vibration is continued until the surface is covered with slurry and no air bubbles overflow.
