Description

Technical Field

[0001] The utility model relates to the technical field of UHPC plastering watering, in particular to a handheld UHPC plastering watering device. Background Art

[0002] CA-UHPC represents one of the most advanced cement-based composite materials in the world. In order to obtain the best mechanical properties of CA-UHPC, a low water-cement ratio is usually adopted, the total amount of cementitious materials is limited, sufficient mineral admixtures and chemical admixtures are added, and the amount of cement is minimized. The water-cement ratio refers to the ratio of the amount of water used in concrete to the amount of cementitious materials used. A low water-cement ratio means that the water content in the concrete is relatively low, which helps to improve the strength and durability of the concrete. However, the low water-cement ratio of CA-UHPC will lead to reduced fluidity and increased viscosity of the concrete, which may make concrete surface construction more difficult.

[0003] At present, in the preparation process of CA-UHPC, the construction site often uses a water spraying pot to level the concrete surface. This method is relatively simple and easy to operate, but it is greatly affected by human subjective factors. Especially in large-scale continuous production, some workers adopt a unified water spraying method for convenience, regardless of whether water spraying is needed, which causes a sharp increase in the water-cement ratio of the concrete surface and affects the quality of the finished product. In addition, on the one hand, a water spraying pot generally does not have a metering function, and a water spraying pot with a metering function is relatively bulky, which is not conducive to the staff to carry while working. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a handheld UHPC plastering sprinkler device, which has the advantages of a simple overall structure to facilitate operation and carrying by staff, and can also achieve quantitative water output through the setting of a flow meter.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0014] As a preferred solution of the utility model, the pressure sensor is threadedly connected to the scraper.

[0015] By adopting the above solution, the pressure sensor is arranged on the scraper by means of threaded connection, which can ensure the stability of the pressure sensor during use, thereby ensuring the accuracy and reliability of the measurement data.

[0017] By adopting the above solution, the handle can be conveniently replenished with water through the water inlet on the handle, thereby improving practicality and simplifying the operation process.

[0018] As a preferred solution of the utility model, the water storage component includes a water storage cavity, the handle has a water storage cavity inside, and the flow meter is connected to the water storage cavity.

[0019] As a preferred solution of the utility model, the water storage component includes a water tank, the handle has an installation cavity inside, the water tank is arranged in the installation cavity, and the flow meter is connected to the water tank.

[0020] As a preferred solution of the utility model, the connecting member is provided with a water supply channel, one end of the water supply channel is connected to the water storage member, and the other end is connected to the flow meter.

[0021] By adopting the above scheme, the water in the water storage member can enter the flow meter through the water delivery channel, thereby improving the water supply speed and efficiency and ensuring the continuity of the plastering process.

[0022] The above-mentioned handheld UHPC plastering sprinkler device has the following beneficial effects: through the integrated pressure sensor and flow meter, accurate control of the moisture in the UHPC plastering process is achieved, the plastering support beam is improved, the influence of human factors is reduced, and the flatness of the concrete surface is ensured.

It is worth noting that the water supply channel 9 is connected to the water tank 31; in some other embodiments, the water storage member 3 includes a water storage cavity, and the end of the water supply channel 9 away from the flow meter 4 is also connected to the handle 2 by welding, and the water supply channel 9 is connected to the water storage cavity; in some other embodiments, the water supply channel 9 may not be opened on the connecting member 1, the flow meter 4 is connected to the water tank 31 by a pipeline, or the flow meter 4 is connected to the water storage cavity. Specifically, the pipeline is also connected to the handle 2 by welding, and the pipeline is connected to the water tank 31 or the water storage cavity, so as to achieve the purpose of providing water to the flow meter 4. It is worth noting that, no matter the water tank 31 or the water storage cavity, a water inlet is provided on the handle 2, and the water inlet is connected to the water tank 31 or the water storage cavity.

[0032] Reference Figure 1 and Figure 2In one embodiment, a pressure sensor 8 is provided on the scraper 5. The pressure sensor 8 is located in the water outlet 6 and connected to the scraper 5. The pressure sensor 8 is connected to the controller 7. In this embodiment, the pressure sensor 8 is installed on the scraper 5 by means of a threaded connection. In some other embodiments, the pressure sensor 8 can also be installed on the scraper 5 by welding or other methods. As long as the pressure sensor 8 can be installed on the scraper 5, it will not be repeated here. When the pressure sensor 8 is provided on the scraper 5, when the staff sprays water on the concrete, they can first contact the scraper 5 with the concrete to make the pressure sensor 8 operate. The pressure value obtained by the pressure sensor 8 is used to judge from the side whether the current concrete hardness should be sprayed with water, which effectively improves the accuracy of concrete spraying and reduces human errors. The pressure sensor 8 is provided on the scraper 5 by means of a threaded connection, which can ensure the stability of the pressure sensor 8 during use, thereby ensuring the accuracy and reliability of the measurement data.

At the same time, through reasonable structural design, the portability and practicality of the device are improved, and the work efficiency of the staff in spraying water on concrete is effectively improved.

[0034] The working principle of the present application is as follows: place the scraper 5 on the concrete surface, start smoothing by manual pressure, and the pressure sensor 8 transmits the pressure data of the manual pressure to the controller 7. When the pressure data is less than or equal to 0.1Pa, the flow meter 4 will not start working. At this time, the concrete surface is relatively soft and no watering is required to carry out the smoothing work; when the pressure data is greater than 0.1Pa, the controller 7 controls the flow meter 4 to start working, and the flow meter 4 releases 10ml of water each time, and the water flows to the concrete surface along the water outlet 6.
