Intelligent defoaming and smoothing device and method for repairing thin layers of chopped fiber cement-based materials

technical field

The invention belongs to the technical field of building construction, and in particular relates to an intelligent defoaming and smoothing device and method for repairing thin layers with chopped fiber cement-based materials.

Background technique

It is known that slurry extraction is an important concept in concrete pouring. In order to separate the concrete into layers through vibration and other actions, the finer slurry floats to the surface under the action of capillary, etc. The process of slurry extraction can not only make the concrete surface smoother, and realize It is beautiful and enhances the effect of surface stress. It can also eliminate air bubbles and make the internal texture of concrete smooth, improving the strength of concrete as a whole.

Therefore, there are many kinds of vibrating and smoothing devices in the prior art based on the above principles, most of which are vibrating motors installed on a flat plate to achieve vibrating and smoothing of concrete. For example, the patent ZL202021650555.8 is a hand-held concrete trowel. The trowel includes a scraper and a handle. The top surface of the scraper and the handle are connected by a connecting rod. A vibration motor and a battery for powering the vibration motor are arranged on the top surface of the scraper. A switch is arranged on the handle, and the battery, the vibrating motor and the switch are connected in series through wires to form a loop. However, the battery is located on the top surface of the scraper, and the vibration during use will cause the battery to vibrate greatly, which is prone to instability. Also, ZL202021861313.3 designed a concrete vibrating and smoothing device, including a base plate, a control rod, a vibrating motor and a battery. The substrate is arranged horizontally, the control rod is located on the upper side of the substrate, one end of the control rod is connected to the substrate, the vibration motor is located on the upper side of the substrate, the battery is located on the control rod, and the battery is electrically connected to the vibration motor.

However, in the process of modern concrete construction, various chopped fibers are often added to increase the strength. It is easy to agglomerate and knot during the pouring and vibration process, resulting in uneven physical properties of the concrete and hidden dangers. Neither of the above two patents Handles fiber clumping in materials incorporating chopped fibers. Moreover, more importantly, for thin-layer repair, the existing vibrating and smoothing device has a relatively fast vibration speed, which is prone to bubbles and is difficult to level. However, if the vibration speed is simply reduced, the vibrating effect will be poor, and it will cost more workers strength and time.

In view of the above deficiencies, the applicant designed this invention by collecting relevant materials, after multiple evaluations and considerations, and based on years of experience accumulated in this industry, through continuous trials and modifications.

【Implementation】

In order to achieve the above-mentioned or other purposes and effects, the technical means and structures adopted in this creation are hereby drawn to illustrate in detail the features and functions of the preferred embodiments of this creation as follows, and the advantages and disadvantages are fully understood.

Please refer to Figures 1 to 3, an intelligent defoaming and smoothing device for repairing thin layers of chopped fiber cement-based materials, including a panel system, a power system, and an intelligent monitoring level adjustment system.

The panel system includes a rough panel 1 and a smooth panel 3 connected at an obtuse angle; in this embodiment, both the rough panel 1 and the smooth panel 2 are 0.5mm thick stainless steel plates, and the rough panel 1 and the smooth panel 3 are welded together , the angle formed by the direction of the non-working surface is 120° to 160°, in order to ensure the connection strength, a connecting rod 2 can be arranged between the rough panel 1 and the smooth panel 3 .

It should be understood that it is necessary to set different vibration frequencies on both sides of the smooth panel 2, and the thinner the stainless steel plate is, the more favorable it is to achieve a larger vibration difference on both sides, but the corresponding rigidity also becomes worse, which is not only easy to Correspondingly, when the stainless steel plate is thicker, its rigidity becomes stronger, but its deformation performance will also decrease, which may cause the vibration sources on both sides to interfere with each other and cannot achieve vibration Poor. According to tests, the boards commonly used in the prior art can achieve the expected effect with a thickness of 0.5 to 2.0 mm. After knowing this principle, it is easy for those skilled in the art to choose the board and its thickness.

The working surface of the rough panel 1 is provided with a carding cone 101; in this embodiment, the shape of the carding cone is conical, with 4 horizontal and 6 vertical distributions, a taper of 1:10, and a root diameter of 5 mm. In order to avoid that when using the smooth panel 2 to work, too long combing teeth 101 will touch the concrete surface and cause interference, the height of the combing cone close to the connection between the rough panel 1 and the smooth panel 2 can be gradually reduced, such as, preferably near the connection The length of the two rows of combing teeth 101 is gradually reduced by 50%, which not only avoids interference, but also uses the method of pulling back when working with the rough panel 1, and can also make the combing teeth transition from short to long. Experiments have proved that this scheme is adopted Not only the combing effect is significantly better, but also the wrist force is significantly reduced.

For the convenience of holding, in some embodiments, a handle bar 12 is also provided. The handle bar 12 is a hollow handle with a battery box 14 inside. The handle bar 12 is connected to the smooth panel 2 through the connecting rod 10. Specifically, the connecting rod 12 The rod 10 is a hollow steel pipe welded to the center of the smooth panel 2, and a hole is reserved near the welding position for threading.

The power system includes a vibration motor 9 arranged on the rough panel 1, and a dual-frequency vibration motor 5 arranged on the smooth panel 2. In this embodiment, there are 4 dual-frequency vibration motors, which are arranged symmetrically near the smooth panel. 3 The positions of the four sides can be specifically referred to as shown in Figure 1; the vibration motor 9 can be selected and set with reference to the prior art, and the dual-frequency vibration motor 5 means that it has two working states. For example, in some embodiments, it can be set but Not limited to the frequency of the first working state is 50HZ, and the frequency of the second working state is 100HZ. In terms of the original surface layer of construction, the quality of the aggregate is not good, the crushing value of the aggregate and the compressive strength of the stone are too poor and slender If the content of flat particles is too high, it is easy to cause bumps. Due to the low frequency of the smoothing device in the prior art, it is not easy to flatten it. Therefore, in the prior art, generally all are to realize flattening by exerting greater pressure, but this will cause wrist fatigue. In this technical solution, different frequencies are set on both sides of the smoothing device to solve this problem, and the effect is good. After testing, when the frequency reaches 100HZ, the flattening effect is the best, and when the frequency reaches 50HZ, the effect of vibration to reduce air bubbles is the best. Therefore, in this embodiment, the low frequency (first working state) of the dual-frequency vibrating motor 9 can be set to 50 Hz, and the high frequency (second working state) can be set to 100 Hz.

The poor strength of thin metal plates is not suitable for direct connection of accessories. Therefore, in some embodiments, the gasket 8 is pre-welded at the position where the accessories need to be connected to ensure the connection strength. The accessories can be welded on the gasket, such as the connecting rod 10. This kind of welding is implemented; screw holes can also be preset on the gasket, and accessories are screwed on the gasket, such as the vibration motor 9 and the dual-frequency vibration motor 10, which can implement this kind of screw connection.

The intelligent monitoring level adjustment system includes a miniature level sensor 13 arranged on the smooth panel 3, the miniature level sensor 13 is electrically connected to the integrated circuit board 12, the vibration motor 9 and the dual-frequency vibration motor 10, and the switch arranged on the handle bar 11 111 and the battery case 14 in the hand-held bar 11, in the present embodiment, level sensor, can choose HCA biaxial horizontal tilt sensor, BLK622 biaxial horizontal tilt sensor in the existing model; Perfect and diverse, strong performance, low power consumption, 8 kilobytes of programming memory, the working cycle can be set, the working voltage is between 3.3 and 5.5V, and the working frequency is between 0 and 40MHz.

The specific setting method is: the switch 111 can be in three gears, when the first gear, only the vibration motor 9 works; when the second gear, the vibration motor 9 stops working, and the dual-frequency vibration motor 10 starts to work. In some embodiments, the specific strategy is as follows: : when the miniature level sensor 13 was horizontal, the dual-frequency vibrating motor 10 was all vibrating at a low frequency; The dual-frequency vibrating motor 10 vibrates at a low frequency. During the third gear, the vibration motor 9 and the dual-frequency vibration motor 10 all do not work. After the above-mentioned strategy mechanism is clarified, it is not difficult to imagine that the miniature level sensor 13 can be arranged laterally along the left and right of the smooth panel 3, so that two groups of dual-frequency vibration motors 10 on the left and right sides vibrate at different frequencies when they are in a non-horizontal position. It can be set vertically and frontally, the principle is the same, the difference is only in the way of use.

An intelligent defoaming and smoothing method for repairing thin layers of chopped fiber cement-based materials, using any one of the above-mentioned intelligent defoaming and smoothing devices for repairing thin layers of chopped fiber cement-based materials; using the rough panel 1 The combing teeth 101 provided on the top vibrate, and the specific method can be: set the switch 111 to a first gear, insert the combing teeth 101 into the repair slurry, comb while vibrating, and comb the direction of the chopped fibers to make them In line with the direction of force, it is conceivable that combing in one direction like combing is more conducive to the smoothness of chopped fibers. When the repair slurry is relatively viscous or bleeding occurs, extend the comb teeth to insert into the repair slurry to vibrate. When pounding, move the rough panel slowly, or insert and pull repeatedly while vibrating, until the slurry reaches a uniform effect. At this point, the switch 111 can be switched to the second gear to carry out the smoothing work. When the vibration frequency is obviously increased, you can stop for a while and press down slightly. Defoaming, vibrating and smoothing, smoothing the smooth panel back and forth in the direction perpendicular to each other, when the smooth panel is in balance, turn off the switch on the hand lever, and finish the surface with a smooth plane;

In some embodiments, the smooth panel 2 is also provided with a level 7, which can assist in leveling and check whether the miniature level sensor 13 works normally.

The above is only a preferred embodiment of the application, and does not limit the technical scope in any way. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the application still belong to the technology of this application. within the scope of the program.
