Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a roughening device for concrete construction joints. Background Technology

[0002] Construction joints are a common practice in concrete engineering construction. They refer to the interface between new and old concrete formed when the pouring process is interrupted due to various reasons. Good construction joint treatment can alleviate the shrinkage and creep of concrete during the hardening process and promote better bonding of the concrete. However, improper treatment of construction joints can also lead to problems such as cracks and leakage in the concrete.

[0003] Currently, the traditional method for treating construction joints involves manually roughening the surface of the concrete during the period between the initial pour and final setting. This typically involves using a hammer, chisel, or steel rod to create uniform grooves on the concrete surface. This serves two purposes: firstly, to enhance the bond between the old and new concrete, thereby increasing the bond strength at the construction joint and ensuring the integrity and durability of the concrete structure; and secondly, to increase the roughness of the contact surface between the old and new concrete, improving the impermeability of the construction joint and preventing cracks or leaks.

[0004] Traditional manual texturing methods are widely used in construction due to their flexibility, adaptability, and simple tools. However, manual texturing also has its limitations. For example, using tools such as hammers, chisels, or steel rods can generate dust and noise, and there is a risk of tools slipping or flying debris causing injury, which can affect the health of workers. At the same time, the labor intensity of workers is high, the efficiency is low, the construction period is long, and the manual texturing effect may be inconsistent in different areas, resulting in inconsistent texturing quality and affecting the overall construction quality. Utility Model Content

[0005] In view of the deficiencies of the prior art described above, the technical problem to be solved by this utility model is to provide a roughening device for concrete construction joints.

[0006] To achieve the above objectives, this utility model provides a roughening device for concrete construction joints, including a support frame and a roughening plate, a vibration mechanism, and a sliding mechanism mounted on the support frame. One end of the support frame is provided with a handle, and the other end is fixedly connected to the roughening plate. The vibration mechanism includes a vibration motor, a power source assembly, and a start / stop button. The vibration motor is connected to the roughening plate and fixedly connected to the support frame. The power source assembly is mounted on the support frame and electrically connected to the vibration motor. The start / stop button is located on the handle and electrically connected to the power source assembly. The sliding mechanism includes a slide groove, a slider, and a foot pedal. The slide groove is formed on the support frame and extends along the length of the support frame. The slider is slidably connected in the slide groove and can move up and down relative to the slide groove. The foot pedal is fixedly connected to one end of the slider.

[0007] Furthermore, the sliding mechanism also includes a return spring, one end of which is connected to the slider and the other end to the bracket. When the bracket moves downward relative to the slide groove, the return spring is in an elastic energy storage state.

[0008] Furthermore, the pressing plate also includes multiple pressing teeth, which are evenly arranged at the bottom of the pressing plate.

[0009] Furthermore, the support is made of steel.

[0010] Furthermore, the bracket is also equipped with a damping shock absorber.

[0011] Furthermore, the power source component is configured as a battery.

[0012] As described above, the concrete construction joint roughening device of this utility model has the following beneficial effects:

[0013] By installing a pressing plate, vibration mechanism, and sliding mechanism on the support, the construction efficiency of pressing is greatly improved. Compared with the traditional manual pressing method, the construction time is greatly shortened, the construction efficiency and quality are improved, the labor intensity of workers is reduced, and the safety hazards caused by manual operation are reduced. At the same time, the overall structure of the pressing device is simple, which makes it very easy for workers to operate and maintain. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] See Figures 1 to 4This utility model provides a roughening device for concrete construction joints, including a support 1, a roughening plate 2 mounted on the support 1, a vibration mechanism 3, and a sliding mechanism 4. One end of the support 1 is provided with a handle 101, and the other end is fixedly connected to the roughening plate 2. The vibration mechanism 3 includes a vibration motor 301, a power source assembly 302, and a start / stop button 303. The vibration motor 301 is connected to the roughening plate 2 and fixedly connected to the support 1. The power source assembly 302 is mounted on the support 1 and electrically connected to the vibration motor 301. The start / stop button 303 is mounted on the handle 101 and electrically connected to the power source assembly 302. Specifically, the vibration motor 301... 01 is used to drive the pressing plate 2 to vibrate, so that the pressing plate 2 can press the texture on the concrete surface. The power source component 302 is used to provide power to the vibration motor 301. The start / stop button 303 is used to control the opening and closing of the power source component 302. The sliding mechanism 4 includes a slide groove, a slider 401 and a foot pedal 402. The slide groove is opened on the bracket 1 and is set along the length extension direction of the bracket 1. The slider 401 is slidably connected in the slide groove and can move up and down relative to the slide groove. The foot pedal 402 is fixedly connected to one end of the slider 401. Preferably, the foot pedal 402 is fixedly connected to the bottom end of the slider 401.

[0025] The basic working principle of the concrete construction joint roughening device of this utility model is as follows: When the roughening device is in use, the worker steps on the foot pedal 402 and presses the handle 101 downward to drive the roughening plate 2 to contact the concrete surface. At this time, the support 1 can slide downward relative to the slider 401 and foot pedal 402 through the sliding mechanism 4, that is, through the sliding groove and the slider 401. The worker can start the power source component 302 through the start / stop button 303, so that the vibration motor 301 drives the roughening plate 2 to vibrate, which makes it easier for the roughening plate 2 to press texture on the concrete surface, increase the surface roughness of the concrete, and meet the requirements of anti-slip and adhesion of the concrete. After the roughening treatment is completed, the worker can turn off the power source component 302 through the start / stop button 303, and move the support 1 upward relative to the slider 401 and foot pedal 402 through the handle 101 and the sliding mechanism 4, so that the worker can roughen other concrete construction joints.

[0026] See Figures 1 to 4 The present invention will be further described below with reference to a specific embodiment:

[0027] In this embodiment, see Figure 1As a preferred design, the sliding mechanism 4 also includes a return spring 403. One end of the return spring 403 is connected to the slider 401, and the other end is connected to the bracket 1. When the bracket 1 moves downward relative to the slide groove, the return spring 403 is in an elastic energy storage state. On the one hand, the return spring 403 can absorb impact energy to a certain extent and reduce the resonance of the bracket 1. On the other hand, when the roughening process is completed, the return spring 403 releases its elastic force, which can drive the bracket 1 to move upward relative to the slider 401 and the foot pedal 402 and automatically return to the initial position.

[0028] In this embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As a preferred design, the textured plate 2 also includes a plurality of textured teeth 201, which are evenly arranged on the bottom of the textured plate 2. The textured teeth 201 can create grooves on the concrete surface, further increasing the surface roughness of the concrete and further improving the anti-slip properties and adhesion of the concrete. Preferably, the number, shape and size of the textured teeth 201 can be flexibly set according to the construction joint, so that the textured teeth 201 can be designed according to the actual needs of the construction joint, which can fully guarantee the actual effect of the textured treatment.

[0029] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the support 1 is made of steel, which has high strength, good plasticity and toughness, is easy to process, and has a low cost.

[0030] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the bracket 1 is also equipped with a damping shock absorber, which can reduce the impact of the vibration motor 301 on the bracket 1 and prevent the bracket 1 from resonating.

[0031] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the power source component 302 is configured as a battery, which can store electrical energy and release it when needed, providing a basis for the portability and mobility of the pressing device, and ensuring the operation of the device in emergency situations.

[0032] As can be seen from the above, the concrete construction joint roughening device of this utility model has the following beneficial effects:

[0033] By setting up a pressing plate 2, a vibration mechanism 3, and a sliding mechanism 4 on the support 1, the construction efficiency of pressing is greatly improved. Compared with the traditional manual pressing method, the construction time is greatly shortened, the construction efficiency and quality are improved, the labor intensity of workers is reduced, and the safety hazards caused by manual operation are reduced. At the same time, the overall structure of the pressing device is simple, which makes it very easy for workers to operate and maintain.

[0034] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
