Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction, and in particular relates to a device for controlling the thickness of thick fireproof coatings for steel structures. Background Technology

[0002] In steel structure construction, fire-retardant coatings are typically applied to the steel surface to ensure fire safety, thereby improving the material's fire resistance and the fire resistance limit of components, and guaranteeing the building's fire resistance performance. In some industrial buildings with special fire protection requirements, the thickness of the fire-retardant coating often exceeds 25mm. Conventional spraying methods make it difficult to precisely control the coating thickness, resulting in poor verticality and flatness of the steel structure surface, leading to substandard appearance and fire resistance, especially at external corners, requiring additional manual treatment. Furthermore, the large area to be covered and the cumbersome application process increase the workload for workers, negatively impacting construction schedules and project costs. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a thickness control device for thick fireproof coating on steel structures, which can accurately control the coating thickness, reduce the labor intensity and workload of workers, and improve construction efficiency.

[0004] The technical solution adopted by this utility model is: a thickness control device for thick fireproof coating on steel structures, including a leveling mechanism and a hand-held mechanism. The leveling mechanism includes a leveling component and a limiting component. The leveling component includes at least one leveling surface. The limiting component is connected to both ends of the leveling component and includes rollers that are parallel to and spaced apart from the leveling surface. The distance between the rollers and the leveling surface is adjustable. The hand-held mechanism is connected to the middle of the leveling component and is used by workers to hold it.

[0005] Furthermore, the limiting component also includes a clamping plate, one end of which is threadedly connected to the scraping component, and the other end extends away from the scraping surface; the roller is movably connected to the clamping plate; the inner side of the clamping plate is provided with several detachable pads, one end of which is flush with the scraping surface.

[0006] Furthermore, the leveling assembly includes a leveling member having the leveling surface and threaded rods disposed at both ends of the leveling member, the threaded rods passing through the clamping plate and the pad.

[0007] Furthermore, the clamping plate is provided with an elongated hole, the length direction of which is perpendicular to the scraping plane; the roller is rotatably connected to a rotating shaft, which passes through the elongated hole.

[0008] Furthermore, the limiting component also includes a fixing member disposed on the outside of the clamping plate. The fixing member is provided with a connecting rod parallel to the length direction of the elongated hole. One end of the rotating shaft is provided with a ring, which is sleeved on the connecting rod and fixed by fasteners.

[0009] Furthermore, the leveling component is provided with a leveling bubble.

[0010] Furthermore, the handheld mechanism includes a pole and magnets disposed at both ends of the pole, and the scraping mechanism is respectively attracted to the magnets.

[0011] Furthermore, it also includes a support mechanism, the two ends of which abut against the leveling mechanism and are disposed opposite to each other on both sides of the handheld mechanism.

[0012] Furthermore, the support mechanism includes a support rod, a sleeve, and a sealing plate. The sleeve is threaded to one end of the support rod, and the sealing plate is respectively disposed at the other end of the support rod and the sleeve.

[0013] A method for controlling the thickness of thick fire-retardant coatings for steel structures, using the aforementioned thick fire-retardant coating thickness control device for steel structures, includes the following steps:

[0014] Manufacturing the leveling mechanism, hand-held mechanism, and support mechanism;

[0015] Before the fire-retardant coating initially sets, the scraping mechanism is temporarily fixed to the steel structure at a set interval;

[0016] Adjust the levelness of the scraping mechanism, the distance between the two side clamps, and the distance between the roller and the scraping surface;

[0018] The handheld mechanism is installed between the leveling mechanism and the support mechanism;

[0019] Slowly move the handheld mechanism, causing the scraping mechanism and the support mechanism to move along the steel structure.

[0020] The advantages and positive effects of this utility model are:

[0021] (1) By setting up a leveling component and a limiting component, the leveling surface of the leveling mechanism and the steel structure are set to have a set distance. The leveling operation is carried out by the leveling mechanism, so that the coating thickness of the fireproof coating is precisely controlled, thereby ensuring that the verticality and flatness of the steel structure after the fireproof coating is applied meet the requirements.

Fireproof coating. Detailed Implementation

[0031] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0032] This utility model provides a device for controlling the thickness of thick fire-retardant coatings on steel structures. This device ensures that the fire-retardant coating is evenly distributed on the surface of the steel structure after application but before initial setting, without requiring additional treatment. This guarantees the coating effect and is simple and quick to operate, reducing labor intensity and workload for workers and improving construction efficiency.

[0033] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a thickness control device for thick fireproof coating on steel structures, including a leveling mechanism 100 and a handheld mechanism 200. The leveling mechanism 100 includes a leveling component and a limiting component. The leveling component includes at least one leveling surface. The limiting component is connected to both ends of the leveling component 101 and includes rollers 108 that are parallel to and spaced apart from the leveling surface. The distance between the rollers 108 and the leveling surface is adjustable. The handheld mechanism 200 is connected to the middle of the leveling component and is used by workers to hold it. The aforementioned scraping surface is used to smooth the fire-retardant coating 500 on the surface of the steel structure 400, and the surface of the steel structure 400 coated with the fire-retardant coating 500 is defined as the coating surface. The aforementioned limiting component is used to limit the position of the scraping surface. It can be understood that the steel structure 400 is usually a three-dimensional structure with multiple surfaces. In this application, the coating surface has opposing surfaces, and the roller 108 rolls in contact with these opposing surfaces. The distance between the roller 108 and the scraping surface is set according to the size of the steel structure 400 and the set coating thickness of the fire-retardant coating 500, so that when the roller 108 is in contact with the opposing surface, the distance between the scraping surface and the coating surface is consistent with the set coating thickness. The handheld mechanism 200 is used to apply external force to the smoothing mechanism 100. To ensure that the roller 108 contacts the opposing surface and moves along the extension direction of the steel structure 400, the roller 108 reduces the friction between the limiting component and the steel structure 400, allowing the scraping mechanism 100 to smoothly scrape the entire coating surface. This enables precise control of the coating thickness of the fire retardant coating 500, achieving uniform application and ensuring that the verticality and flatness of the steel structure 400 meet requirements after applying the fire retardant coating 500. The entire device is easy to use, reducing the labor intensity and workload of workers and improving construction efficiency. Furthermore, by making the distance between the scraping surface and the roller 108 adjustable, different coating thickness requirements can be met, further expanding the applicability of the device.

[0034] The aforementioned steel structure 400 can be a steel column or a steel beam, and the coating surface can be a vertical or horizontal surface; the cross-sectional shape of the steel structure 400 can be square, rectangular, or other polyhedrons; correspondingly, the number of rollers 108 can be one or two; in a specific embodiment, the steel structure 400 is an H-beam, the coating surface is the outer surface of its flange, the opposite surface is the inner surface of the flange, and two rollers 108 are set, respectively corresponding to the free ends of the flanges; in other embodiments of this application, when the steel structure 400 is a steel column with a rectangular cross-sectional shape, one roller 108 can also be set.

[0035] Furthermore, such as Figure 1As shown, the aforementioned limiting assembly also includes a clamping plate 105, one end of which is threadedly connected to the leveling assembly, and the other end extends away from the leveling surface. A roller 108 is movably connected to the clamping plate 105. Several removable pads 110 are provided on the inner side of the clamping plate 105, one end of which is flush with the leveling surface. The clamping plate 105 is used to clamp the two sides of the steel structure 400, providing an installation base for the roller 108 and also forming a lateral limiting effect on the leveling assembly, ensuring the stability and uniformity of the leveling operation as the leveling assembly performs leveling work along the set route and direction. When both sides of the steel structure 400 also need to be coated with fire-retardant paint 500, by reasonably setting the spacing between the clamping plates 105, three surfaces of the steel structure 400 can be leveled simultaneously, effectively ensuring the perpendicularity of the external corners of the steel structure 400. By setting the clamping plate 105 to be threadedly connected to the leveling assembly, the clamping plate 105 and the leveling assembly... The connection position of the components can be adjusted as needed, so that the distance between the two clamping plates 105 is adapted to the size of the steel structure 400 and the set coating thickness. The aforementioned pad 110 is used to fill the gap between the clamping plate 105 and the scraping surface. When the length of the scraping surface is less than the width of the coating surface of the steel structure 400, by adjusting the number of pads 110, the end face formed by the scraping surface and the pads 110 is connected to form an expanded scraping surface, which is adapted to the width of the coating surface. Through the above settings, the distance between the clamping plates 105 and the expanded scraping surface can be adapted to steel structures 400 of different specifications. By moving the scraping mechanism 100, the scraping operation within the entire coating surface area can be completed, ensuring that the fireproof coating 500 is uniformly applied to the steel structure 400 at the set thickness, improving the coating effect and work efficiency of the fireproof coating 500. It also makes the device applicable to steel structures 400 of various specifications, further expanding the applicability of the device.

[0036] The aforementioned leveling assembly includes a leveling component 101 with a leveling surface and threaded rods 103 disposed at both ends of the leveling component 101. The threaded rods 103 pass through the clamping plate 105 and the pad 110. In a specific embodiment, the leveling component 101 is made of square steel tubing. Both the clamping plate 105 and the pad 110 are provided with connecting holes adapted to the threaded holes. One end of the threaded rod 103 is welded to the square steel tubing, and the other end passes through the connecting holes on the clamping plate 105 and the pad 110, and is fixed by bolts. The leveling component 101, the threaded rod 103, the clamping plate 105, and the pad 110 are connected to form an integral structure with good stability. Through this arrangement, the spacing between the clamping plates 105 can be adjusted, and the length of the expanded leveling surface formed after the pad 110 is connected to the leveling surface can also be adjusted. The adjustment is simple and easy to control.

[0037] Furthermore, in this embodiment, the clamping plate 105 is provided with an elongated hole 109, the length direction of which is perpendicular to the scraping plane; the roller 108 is rotatably connected to the rotating shaft 107, which passes through the elongated hole 109. By adjusting the position of the rotating shaft 107 along the length direction of the elongated hole 109, the distance between the roller 108 and the scraping plane can be adjusted to meet the set thickness requirements for applying the fire-retardant coating 500.

[0038] In one specific embodiment, there is one shaft 107 and one roller 108. The two ends of the shaft 107 pass through the elongated holes 109 on the two side clamps 105 and are fixed to the clamps 105 with bolts. In another specific embodiment, there are two shafts 107 and two rollers 108, which are arranged opposite each other in the elongated holes 109 on the two side clamps 105. The two sides of the shaft 107 are fixed to the clamps 105 with bolts. The end of the shaft 107 away from the clamps 105 is provided with a limiting pin for preventing the roller 108 from disengaging from the shaft 107.

[0039] Furthermore, to further precisely adjust the distance between the roller 108 and the scraping surface, the limiting component in this embodiment also includes a fixing member 106 disposed on the outside of the clamping plate 105. The fixing member 106 is provided with a connecting rod parallel to the length direction of the elongated hole 109. One end of the rotating shaft 107 is provided with a ring, which is sleeved on the connecting rod and fixed by a fastener 104. The ring is disposed at the end of the rotating shaft 107 that passes through the clamping plate 105. By adjusting the position of the ring on the connecting rod, the rotating shaft 107 can be moved along the length direction of the elongated hole 109, thereby improving the adjustment accuracy. The connecting rod is provided with an external thread, and the fastener 104 is provided with an internal thread. By fixing the fastener 104 to both sides of the ring, the ring can be firmly fixed in the set position of the connecting rod, thereby enhancing the stability of the connection between the rotating shaft 107 and the clamping plate 105.

[0040] Furthermore, the aforementioned leveling component 101 is equipped with a leveling bubble 102. In a specific embodiment, the fire-retardant coating 500 thickness control device proposed in this application is used for leveling the fire-retardant coating 500 on the vertical plane of a steel column. The leveling component 101 is made of square steel tubing, with one side of the square steel tubing serving as the leveling surface. The leveling bubble 102 is set on the other side of the square steel tubing, facing outwards or upwards during use. Construction personnel can conveniently adjust the levelness of the leveling component 101 by observation, thereby ensuring that the spacing between the clamping plates 105 matches the width of the steel column. The leveling component 101 can move up and down along the steel column to complete the leveling operation on the entire coating surface of the steel column, thus avoiding the situation where some areas cannot be reached due to the leveling component 101 being tilted. When used for leveling the fire-retardant coating 500 on the horizontal plane of a steel beam, the leveling bubble 102 can also ensure the consistency of the spacing between the leveling surface and the coating surface.

[0041] Preferably, in one embodiment of this application, such as Figure 2 As shown, the handheld mechanism 200 in this application includes a pole 201 and magnets 203 disposed at both ends of the pole 201. The leveling mechanism 100 is respectively attracted to the magnets 203. That is, there are two leveling mechanisms 100, which are respectively connected to both ends of the handheld mechanism 200. The two leveling mechanisms 100 cooperate to perform leveling operations on the coating surface in turn, so as to further improve the leveling effect, reduce the number of reciprocating movements of the device, and thus improve the efficiency of the leveling operation.

[0042] In the above embodiment, the handheld mechanism 200 also includes a handle 202, which is located in the middle of the upright 201 so that construction personnel can hold it; the magnet 203 has sufficient adsorption force to stably fix the leveling mechanism 100 at both ends of the handheld mechanism 200, and by moving the handheld mechanism 200, the two leveling mechanisms 100 can be moved synchronously.

[0043] Furthermore, such as Figure 3 As shown, the fire-retardant coating 500 thickness control device proposed in this application embodiment further includes a support mechanism 300. The two ends of the support mechanism 300 abut against the leveling mechanism 100 and are respectively disposed on both sides of the handheld mechanism 200. By providing the support mechanism 300, the two leveling mechanisms 100 are supported by the handheld mechanism 200 and the support mechanism 300, ensuring that the distance between the two leveling mechanisms 100 remains consistent along their length. This improves the stability of the leveling mechanisms 100 during leveling operations, preventing tilting or deviation and ensuring the uniformity of the fire-retardant coating 500 thickness.

[0044] In the above embodiment, the support mechanism 300 includes a support rod 301, a sleeve 303, and a sealing plate 302. The sleeve 303 is threaded to one end of the support rod 301, and the sealing plate 302 is respectively disposed at the other end of the support rod 301 and the sleeve 303. The sealing plate 302 has a connecting surface for abutting against the leveling component 101 to ensure a stable connection between the sealing plate 302 and the leveling component 101. By providing the sleeve 303, the overall length of the support mechanism 300 can be adjusted to achieve abutting connection with the leveling components 101 on both sides.

[0045] The aforementioned steel structure thick fireproof coating thickness control device is made of common materials found on construction sites, making it easy to process and inexpensive. At the same time, the leveling mechanism 100, the hand-held mechanism 200, and the support mechanism 300 are all connected in a detachable manner, making them easy to assemble and store.

A fixing component 106 is welded to the clamping plate 105, aligning the connecting rod of the fixing component 106 with the elongated hole 109 of the end plate. A rotating shaft 107 is passed through the elongated hole 109, and the ring at one end of the rotating shaft 107 is fitted onto the connecting rod, locked with nuts on both sides. Then, a roller 108 is fitted onto the rotating shaft 107, and a limiting pin is installed at the other end of the rotating shaft 107, completing the fabrication of the leveling assembly and the limiting assembly. Subsequently, according to the width of the coating surface of the steel structure 400, the clamping plate 105 and a matching number of pads 110 are installed on the threaded rod 103 and initially fixed with bolts. Based on the set coating thickness and the dimensions of the steel structure 400, the positions of the ring and fasteners 104 are initially adjusted, completing the assembly of the leveling mechanism 100.

[0049] Install the handle 202 in the middle of the upright 201, and then embed the magnet 203 at both ends of the upright 201 to complete the assembly of the hand-held mechanism 200.
