Embodiment 2

[0044] A fireproof paint spraying device for steel structures, in order to further make the device uniform when spraying steel structures, such as Figure 5 As shown, this embodiment makes the following additions on the basis of Embodiment 1: the outer wall of the top of the nozzle base 304 is fixedly connected with a hollow base 311; the inner wall of the bottom of the hollow base 311 is fixedly connected with a telescopic spring 312; the telescopic spring 312 A telescopic link 313 is fixedly connected to the top outer wall; the outer wall around the telescopic link 313 is slidably connected to the inner wall of one side of the hollow base 311 .

[0045] In order to make the fireproof coating rotate and spray inside the spray nozzle 3, as Figure 5 As shown, the outer wall of the top end of the telescopic connecting rod 313 is rotatably connected with a blocking ball 314; the diameter of the blocking ball 314 is greater than the inner diameter of the outlet cylinder 301; cyl...

Embodiment 3

[0048] A fireproof paint spraying device for steel structures, in order to enable the device to realize the function of instant start-up and stop-off function, such as Figure 6 , Figure 7 As shown, this embodiment makes the following improvements on the basis of Embodiment 2: the inner wall of the bottom end of the nozzle base 304 is fixedly connected with the electric telescopic rod 321 by screws; The telescopic rod 321 is electrically connected with the internal control unit; the gap between the ball 314 and the outlet cylinder 301 is controlled by the electric telescopic rod 321. When the electric valve inside the electric valve box 4 stops operating, there is a fireproof paint inside the outlet cylinder 301. And the operation of the electric telescopic rod 321 will block the export tube 301 by blocking the ball 314, so that the fireproof coating inside the export tube 301 cannot overflow, and realize the instant function of the device, that is, stop when it is closed.

Abstract

The invention discloses a fireproof coating spraying device for a steel structure and a spraying method of the fireproof coating spraying device, and relates to the technical field of steel structure fireproof coating spraying. The problem that a steel structure is not uniform when a fireproof coating is sprayed is solved. The fireproof coating spraying device for the steel structure comprises a spraying rack and a stirring box. A conveying belt is arranged on the inner wall of one side of the spraying rack, and fixing mechanisms are arranged on the inner walls of the two sides of the spraying rack. The spraying method of the fireproof coating spraying device for the steel structure comprises the following steps that fireproof coating raw materials are added into the stirring box through a feeding opening, a driving motor is started, and the raw materials in the stirring box are stirred for 30 minutes. The steel structure moves on the conveying belt, the steel structure is moved to the position below spraying nozzles through the fixing mechanisms, multiple electric valves are arranged in an electric valve box and connected with the multiple spraying nozzles correspondingly, and therefore the device can conduct fireproof coating spraying on the steel structure quickly, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fireproof paint spraying for steel structures, in particular to a fireproof paint spraying device for steel structures and a spraying method thereof. Background technique [0002] Steel is a non-combustible building material. It has the characteristics of earthquake resistance and bending resistance. In practical applications, steel can not only increase the load capacity of buildings, but also meet the needs of architectural design aesthetics; it also avoids the need for concrete Such building materials cannot be bent or stretched. However, as a building material, steel has some unavoidable defects in fire prevention. Its mechanical properties, such as yield point, tensile strength and elastic modulus, will all be affected by the temperature rise. Therefore, it is necessary to spray fireproof coatings on steel structures. At present, in the prior art, fireproof coatings on steel structures are sprayed ma...
