Description

Technical Field

[0001] The utility model relates to the technical field of coating thickness detection, in particular to a thick fire retardant coating thickness controller. Background Art

[0002] Thick fire retardant coating is a commonly used fire retardant material in building fire protection. During the steel structure construction process, the spray thickness of the thick fire retardant coating determines whether it can achieve the fire protection effect required by the specification. However, on many irregularly shaped special-shaped steel structures and curved steel structures, conventional spray fire retardant coating is difficult to spray evenly and cannot guarantee the fire protection effect. At the same time, it affects the appearance of the structure and the subsequent renovation workload is large.

[0003] Publication No. CN109059724A discloses a fire retardant coating thickness detection device for building components, which includes a base and a pointed rod, and the pointed rod is connected as a whole. The pointed rod is composed of a conical end and a cylindrical connecting section. The cylindrical connecting section is connected to the base, and the diameter of the cylindrical connecting section is smaller than the diameter of the base. The base and the pointed rod have the same center line. The distance between the end point of the conical end and the end face of one end of the base connected to the pointed rod is the minimum value of the fire retardant coating thickness of the building component. A movable movable connecting piece is provided in the first horizontal connecting hole and the second horizontal connecting hole. The structure of the present invention is very simple, the detection is accurate, and it is practical and reliable.

[0004] However, when the above-mentioned device detects the fire retardant coating, it is necessary to detect the thickness of the fire retardant material after the fire retardant coating is sprayed or during the spraying process to detect whether the spraying thickness of the fire retardant coating meets the requirements. This requires manual stopping of the spraying for multiple times during the spraying process to detect whether the spraying thickness of the fire retardant coating meets the requirements, which increases the cumbersome process of use. Moreover, when the spraying thickness has only a slight thickness difference, there is no relevant direct reference object, and it is difficult to manually control the spraying thickness to exactly meet the thickness requirement, thereby reducing the accuracy of the spraying thickness. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a thick fire retardant coating thickness controller to solve the problem in the prior art that when testing the fire retardant coating, it is necessary to test the thickness of the fire retardant material after the fire retardant coating is sprayed or during the spraying process to detect whether the spraying thickness of the fire retardant coating has reached the requirement. This results in the need to manually stop the spraying for multiple times during the spraying process to detect whether the spraying thickness of the fire retardant coating has reached the requirement, which increases the cumbersome process of use. Moreover, when the spraying thickness has only a slight thickness difference, there is no relevant direct reference object, and it is difficult to manually control the spraying thickness to just reach the thickness requirement, thereby reducing the accuracy of the spraying thickness.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A thick fire retardant coating thickness controller comprises a plastic sleeve, the upper end of which is detachably connected with a thickness control sheet, and the bottom of which is connected with a magnetic attraction piece.

[0008] As a further solution of the utility model: it also includes multiple groups of extension tubes, and the multiple groups of extension tubes are connected between the plastic sleeve and the thickness control sheet.

[0009] As a further solution of the utility model: an inner thread groove is formed at one end of the plurality of extension tubes, a stud is fixedly connected to the other end of the plastic sleeve, and the plurality of extension tubes are threadably connected to each other.

[0010] As a further solution of the utility model: a threaded buckle is fixedly connected to the middle of one side of the thickness control sheet, and the threaded buckle is threadedly connected to the plastic sleeve.

[0011] As a further solution of the utility model: the magnetic attraction component includes a neodymium magnet, the bottom of the plastic sleeve is fixedly connected with a plastic slot, and the neodymium magnet is arranged inside the plastic slot.

[0012] As a further solution of the utility model: a plurality of groups of slots are provided on the thickness control sheet.

[0013] Beneficial effects of the utility model:

[0014] 1. In the utility model, the upper end of the plastic sleeve is threadedly connected and fixed with the upper end of the thickness control sheet, and then the neodymium magnet is used to absorb it into the spraying range of the steel structure.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, a thick fire retardant coating thickness controller includes a plastic sleeve 1, the upper end of the plastic sleeve 1 is detachably connected to a thickness control sheet 2, the bottom of the plastic sleeve 1 is connected to a magnetic suction piece 3, and the plastic sleeve 1, the thickness control sheet 2 and the magnetic suction piece 3 form a T-shaped whole that is adsorbed on the outer wall of the steel structure for use.

[0025] like Figure 2 and Figure 3 As shown, the above-mentioned thick fire retardant coating thickness controller also includes multiple groups of extension tubes 4, which are connected between the plastic sleeve 1 and the thickness control plate 2. An inner screw groove 401 is opened at one end of the multiple groups of extension tubes 4, and a stud 402 is fixedly connected to the other end of the plastic sleeve 1. The multiple groups of extension tubes 4 are threadedly connected to each other. By setting the multiple groups of extension tubes 4, the height of the thickness control plate 2 on the steel structure can be increased or decreased, which is convenient for controlling the different thickness requirements of the fire retardant coating sprayed on the steel structure, thereby improving the convenience of use. The setting of the inner screw groove 401 and the stud 402 at both ends of the extension tube 4 facilitates the connection between the multiple groups of extension tubes 4, and also facilitates the connection between the extension tube 4 and the plastic sleeve 1 and the thickness control plate 2.

[0026] like Figure 1 and Figure 2 As shown, a threaded buckle 202 is fixedly connected in the middle of one side of the thickness control sheet 2, and the threaded buckle 202 is threadedly connected to the plastic sleeve 1 to complete the installation and fixation of the thickness control sheet 2 and improve the convenience of installation and disassembly.

[0027] like Figure 1 and Figure 5 As shown, the magnetic attraction component 3 includes a neodymium magnet 301, a plastic slot 302 is fixedly connected to the bottom of the plastic sleeve 1, the neodymium magnet 301 is arranged inside the plastic slot 302, and the plastic sleeve 1 and the plastic slot 302 are connected by adhesive bonding. Before connection, the neodymium magnet 301 is placed inside the plastic slot 302, and at the same time, multiple neodymium magnets 301 can be prevented to increase the stability of magnetic adsorption between the neodymium magnet 301 and the steel structure.

[0028] like Figure 1 and Figure 4 As shown, the thickness control sheet 2 is provided with a plurality of groups of grooves 201. The arrangement of the grooves 201 makes it convenient to observe the thickness of the fire retardant coating sprayed below the thickness control sheet 2, and also makes it convenient to spray the fire retardant coating below the thickness control sheet 2, thereby avoiding a large gap below the thickness control sheet 2.

[0029] The working principle of the utility model is as follows: during the specific implementation, the neodymium magnet 301 is put into the plastic card slot 302, and then the plastic card slot 302 is fixedly connected to the bottom of the plastic sleeve 1 by means of adhesive bonding, and the upper end of the plastic sleeve 1 is threadedly connected and fixed with the upper end of the thickness control sheet 2 by means of the threaded buckle 202 to form a whole, and then the neodymium magnet 301 itself is magnetically adsorbed to the steel structure spraying range, and when the fire retardant coating is sprayed, the thickness of the fire retardant coating on the surface of the steel structure is observed, and when the thickness reaches the bottom of the thickness control sheet 2, the spraying of the fire retardant coating is stopped, and at this time, the fire retardant coating reaches the required thickness for spraying, and there is no need to manually insert the fire retardant coating multiple times. The spray thickness of the fire retardant coating is measured to improve the convenience of thickness control. At the same time, it is convenient to accurately control the thickness of the fire retardant coating sprayed, improve the accuracy of the fire retardant coating spray thickness, and then pull the fire retardant coating thickness controller out of the fire retardant coating, and then fill the holes left by the fire retardant coating thickness controller with fire retardant coating to complete the spraying of the fire retardant coating. The fire retardant coating thickness control can be set up in multiple groups on the steel structure for use, so that the fire retardant coating can be sprayed evenly and flatly on the steel structure, reducing the subsequent finishing workload and achieving a smooth effect on the entire coating surface. After spraying in one spraying range is completed, the thickness controller will be used for the next spraying area.

[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
