Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to a device for monitoring the thickness of continuous and uninterrupted spraying of fireproof coatings on steel structures. Background Technology

[0002] During the application of fire-retardant coatings to steel structures, it is necessary to measure the coating thickness to confirm whether it meets the design standards. In this field, manual measurement is usually used. This method requires the operator to stop the spraying operation and use measuring tools to measure whether the coating thickness meets the standard. This usually requires multiple measurements, which not only affects the spraying speed but also causes quality problems such as uneven thickness, inconsistent transitions, and coating layering due to repeated spraying operations. Summary of the Invention

[0003] The purpose of this invention is to provide a thickness monitoring device for continuous and uninterrupted spraying of fireproof coatings on steel structures, in order to solve the quality problems caused by repeated spraying operations due to operators stopping spraying to measure and check whether the coating thickness meets the standard, resulting in uneven thickness, discontinuous joints, and coating delamination.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a thickness monitoring device for continuous uninterrupted spraying of fireproof coating on steel structures, including a magnet and a zinc oxide electrode sheet connected thereto, wherein the sum of the thicknesses of the magnet and the zinc oxide electrode sheet is equal to the design value of the spraying thickness, and also including a power supply and an indicator light, wherein the power supply, the indicator light and the zinc oxide electrode sheet are connected by wires to form a series circuit.

[0005] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying thickness monitoring device provided by the present invention, the steel structure surface is flat, and the corresponding magnet and its connected zinc oxide electrode sheet are also flat.

[0006] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying thickness monitoring device provided by the present invention, the steel structure surface is an arc-shaped surface, and the corresponding magnet and its connected zinc oxide electrode sheet are also arc-shaped surfaces.

[0007] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the magnet and the zinc oxide electrode sheet are detachably connected.

[0008] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the magnet is a neodymium iron boron magnet.

[0009] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, both the magnet and the zinc oxide electrode sheet are annular.

[0010] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the zinc oxide electrode sheet includes an annular base and an annular wall.

[0011] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the power source is a rechargeable battery.

[0012] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the rechargeable battery is a lithium battery.

[0013] Furthermore, in the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device provided by the present invention, the indicator light is an LED light.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The steel structure fire-retardant coating continuous uninterrupted spraying thickness monitoring device provided by this invention, before the steel structure is sprayed, is magnetically attached to the steel structure, and the zinc oxide electrode is exposed to the air. Its resistance value is extremely high, causing the series circuit to be in a broken state, at which time the indicator light is off. During the continuous uninterrupted spraying of the fire-retardant coating on the steel structure, when the fire-retardant coating covers the end of the zinc oxide electrode, the zinc oxide electrode is blocked from contact with the air by the sprayed fire-retardant coating. The resistance value of the zinc oxide electrode decreases, causing the series circuit to be in a closed state, and the indicator light is lit, indicating that the spraying thickness of the fire-retardant coating on the steel structure has reached the design value, and the spraying operation is stopped. Compared to manually measuring whether the thickness of the fire-retardant coating reaches the design value, this method enables continuous and uninterrupted one-time spraying of fire-retardant coating on steel structures. This avoids the quality problems caused by repeated spraying operations due to manual measurement after stopping the spraying operation, which can lead to uneven thickness, discontinuous joints, and coating delamination. It has the advantages of uniform, continuous, and non-delamination fire-retardant coating thickness, thereby improving the spraying quality of fire-retardant coating on steel structures.

[0015] To solve the above-mentioned technical problems, another technical solution provided by the present invention is: a thickness monitoring device for continuous and uninterrupted spraying of fireproof coating on steel structures, comprising a magnet and a detachably connected calibration component, wherein the sum of the thicknesses of the magnet and the calibration component is equal to the design value of the spraying thickness.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The steel structure fire-retardant coating continuous spraying thickness monitoring device provided by this invention uses a magnet to adhere to the steel structure before spraying. The fire-retardant coating is continuously sprayed onto the steel structure. When the thickness of the fire-retardant coating reaches the end of the calibration component, it indicates that the coating thickness has reached the design value, and spraying stops. Compared with manually measuring the coating thickness, this device allows for continuous, uninterrupted, one-time spraying of fire-retardant coating onto the steel structure. It avoids the quality problems caused by repeated spraying operations due to manual measurement after stopping spraying, which can lead to uneven coating thickness, discontinuous transitions, and coating delamination. It offers the advantages of uniform, continuous, and non-delaminating fire-retardant coating thickness, thereby improving the spraying quality of fire-retardant coatings on steel structures. By changing the thickness of the calibration component, online detection of fire-retardant coatings with different thickness standards can be performed. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0019] Example 1 Please refer to Figures 1 to 3Embodiment 1 of the present invention provides a thickness monitoring device 100 for continuous uninterrupted spraying of fireproof coating on steel structures, including a magnet 101 and a zinc oxide electrode 102 connected thereto. The sum of the thicknesses of the magnet 101 and the zinc oxide electrode 102 is equal to the design value of the spraying thickness. It also includes a power supply 103 and an indicator light 104. The power supply 103, the indicator light 104 and the zinc oxide electrode 102 are connected by a wire 105 to form a series circuit.

[0020] The steel structure fireproof coating continuous uninterrupted spraying thickness monitoring device 100 provided in Embodiment 1 of the present invention, before spraying the steel structure 200, is attracted to the steel structure 200 by a magnet 101, and the zinc oxide electrode 102 is exposed to the air. Its resistance value is extremely high, so the series circuit is in an open state, and the indicator light 104 is off at this time. During the continuous uninterrupted spraying of the fireproof coating on the steel structure 200, when the fireproof coating covers the end of the zinc oxide electrode 102, the zinc oxide electrode 102 is blocked from contact with the air by the sprayed fireproof coating. The resistance value of the zinc oxide electrode 102 decreases, so the series circuit is in an open state, and the indicator light 104 is lit, indicating that the spraying thickness of the fireproof coating on the steel structure 200 has reached the design value, and the spraying operation is stopped. Compared to manually measuring whether the thickness of the fire-retardant coating reaches the design value, this method enables continuous and uninterrupted one-time spraying of fire-retardant coating on the steel structure 200, i.e., online monitoring. This avoids the quality problems caused by repeated spraying operations due to manual measurement after stopping the spraying operation (i.e., offline monitoring), which can lead to uneven thickness, discontinuous joints, and coating delamination. It has the advantages of uniform, continuous, and non-delamination fire-retardant coating thickness, thereby improving the spraying quality of fire-retardant coating on the steel structure 200.

[0021] The steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device 100 provided in Embodiment 1 of the present invention consists of a magnet 101, a zinc oxide electrode 102, a power supply 103, an indicator light 104 and a wire 105. It has the advantages of simple structure, small size, easy use, does not interfere with the spraying construction, and has simple and efficient measurement.

[0022] To adapt to steel structures 200 with different surfaces, the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device 100 provided in Embodiment 1 of the present invention has the following characteristics: the surface of the steel structure 200 is a plane, and the corresponding magnet 101 and its connected zinc oxide electrode sheet 102 are also planes; the surface of the steel structure 200 is an arc-shaped surface, and the corresponding magnet 101 and its connected zinc oxide electrode sheet 102 are also arc-shaped surfaces.

[0023] To facilitate monitoring of design values ​​for different coating thicknesses, Embodiment 1 of this invention provides a continuous, uninterrupted coating thickness monitoring device 100 for fire-retardant coatings on steel structures. The magnet 101 is detachably connected to the zinc oxide electrode 102. By changing the thickness of the zinc oxide electrode 102, the design value of the coating thickness can be altered, thereby monitoring different coating thicknesses and meeting the needs of various application scenarios.

[0024] To improve the adsorption effect, the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device 100 provided in Embodiment 1 of the present invention uses a neodymium iron boron magnet 101 as the magnet 101.

[0025] To reduce costs, the steel structure fireproof coating continuous uninterrupted spraying thickness monitoring device 100 provided in Embodiment 1 of the present invention includes a magnet 101 and a zinc oxide electrode 102, both of which are annular. The zinc oxide electrode 102 may include an annular base and an annular wall.

[0026] To reduce interference from wiring harnesses during spraying operations, the steel structure fireproof coating continuous uninterrupted spraying thickness monitoring device 100 provided in Embodiment 1 of this invention uses a rechargeable battery as its power source 103. To reduce size, the rechargeable battery can be a lithium battery.

[0027] To facilitate the operation of the indicator light 104, the steel structure fireproof coating continuous uninterrupted spraying operation thickness monitoring device 100 provided in Embodiment 1 of the present invention uses an LED light as the indicator light 104.

[0028] Example 2 Please refer to Figure 4This invention provides a second embodiment of a device 100 for monitoring the thickness of continuous, uninterrupted spraying of fire-retardant coatings on steel structures. It is an improvement upon the first embodiment, differing in that a calibration component 106 replaces the zinc oxide electrode 102, and the power supply 103, indicator light 104, and wires 105 are removed. Specifically, it includes a magnet 101 and a detachably connected calibration component 106. The sum of the thicknesses of the magnet 101 and the calibration component 106 equals the designed spraying thickness. The calibration component 106 can be made of any material; for easy detachable connection with the magnet 101, it can be made of steel, allowing for detachable magnetic connection. To reduce costs, both the magnet 101 and the zinc oxide electrode 102 are annular. The zinc oxide electrode 102 may include an annular base and an annular wall. To improve adsorption capacity, the magnet 101 can be a neodymium iron boron magnet 101. To accommodate steel structures 200 with different surfaces, when the surface of the steel structure 200 is flat, the corresponding magnet 101 and its connected calibration component 106 are both flat; when the surface of the steel structure 200 is curved, the corresponding magnet 101 and its connected calibration component 106 are both curved.

[0029] The steel structure fire-retardant coating continuous uninterrupted spraying thickness monitoring device 100 provided in Embodiment 2 of the present invention, before the steel structure is sprayed, is attracted to the steel structure by a magnet 101, and the fire-retardant coating is continuously sprayed onto the steel structure. When the thickness of the fire-retardant coating reaches the end of the calibration component 106, it indicates that the thickness of the fire-retardant coating on the steel structure has reached the design value, and the spraying operation is stopped. This achieves online monitoring of the thickness of the fire-retardant coating while continuously spraying, i.e., online monitoring. Compared with the method of manually measuring whether the thickness of the fire-retardant coating reaches the design value, it can achieve continuous and uninterrupted one-time spraying of fire-retardant coating on the steel structure, avoiding the quality problems of uneven thickness, discontinuous connection, and coating delamination caused by repeated spraying operations due to manual measurement after stopping the spraying operation (i.e., offline monitoring). It has the advantages of uniform, continuous, and non-delamination fire-retardant coating thickness, thereby improving the spraying quality of fire-retardant coating on steel structures. By changing the thickness of the calibration component 106, online testing can be performed on fire-retardant coatings of different thickness standards.
