Description

Technical Field

[0001] This patent relates to the field of building spraying protection technology, specifically to a protective device for spraying paint on steel structure columns and beams. Background Technology

[0002] Currently, steel structure design is widely used in the construction industry to meet the requirements of assembly rate. After the steel structure is installed, fireproof coating needs to be sprayed. Generally, the fireproof coating for steel structure columns is non-expandable, while that for steel structure beams is expansive. The two are different in terms of material properties and thickness. At the junction of beams and columns, the traditional method is to use double-sided tape or ordinary tape to fix plastic film for protection. This is not effective, and the double-sided tape is difficult to clean and requires a lot of labor.

[0003] Therefore, it is essential to design a steel structure spray anti-pollution tool to address the above technical issues. Summary of the Invention

[0004] The purpose of this utility model is to provide a steel structure spraying anti-pollution tool to solve the problem of difficult protection of finished sprayed products during the construction of steel structures.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for spraying paint on steel structure columns and beams includes a fixed corner frame, a movable corner frame, an adjuster, a telescopic pressure bar, and a protective plate. The movable corner frame includes a movable horizontal bar and a movable vertical bar connected perpendicularly to each other. The fixed corner frame includes a fixed horizontal bar and a fixed vertical bar that are perpendicular to each other. The movable horizontal bar is slidably sleeved on the outside of the fixed horizontal bar. The movable vertical bar and the fixed vertical bar are respectively located at the far ends of the movable horizontal bar and the fixed horizontal bar. The telescopic pressure bar is sleeved on the inside of the movable vertical bar and / or the fixed vertical bar. The adjuster includes a corner frame adjuster for adjusting the distance between the fixed corner frame and the movable corner frame, and a pressure bar adjuster for limiting the telescopic length of the telescopic pressure bar. The fixed corner frame, the movable corner frame, and the telescopic pressure bar form a frame structure, and the protective plate is laid inside the frame structure.

[0007] The aforementioned protective devices for coating steel structure columns and beams use hollow rods for fixed corner brackets, movable corner brackets, and telescopic pressure bars; movable horizontal bars and movable vertical bars are connected by welding; and fixed horizontal bars and fixed vertical bars are connected by welding.

[0008] The aforementioned protective device for spraying paint on steel structure columns and beams includes a corner bracket adjuster comprising a connecting screw, a connecting nut, a fixing plate, an adjusting plate, and an adjusting hole. The fixing plate seals the far end of the movable crossbar. The adjusting plate is located at the joint between the fixed crossbar and the movable crossbar. The adjusting holes are respectively located on the fixing plate and the adjusting plate. The connecting nut is located in the cavity of the fixed crossbar. The connecting screw passes sequentially through the adjusting hole of the fixing plate, the cavity of the movable crossbar, and the adjusting hole of the adjusting plate before being screwed into the connecting nut.

[0009] The aforementioned protective device for coating spraying of steel structure columns and beams includes a pressure rod adjuster comprising a pressure rod screw hole and a pressure rod bolt. The pressure rod screw hole is located on the upper part of the movable vertical rod or the fixed horizontal rod, and the pressure rod bolt is screwed into the pressure rod screw hole and abuts against the telescopic pressure rod.

[0010] The aforementioned protective device for coating spraying on steel structure columns and beams includes a telescopic pressure bar comprising a telescopic vertical bar and a horizontal pressure bar. The telescopic vertical bar is sleeved inside the movable vertical bar or the fixed vertical bar, and the horizontal pressure bar is parallel to the movable horizontal bar.

[0011] The aforementioned protective device for coating spraying on steel structure columns and beams includes a protective plate and a baffle. The protective plate is laid flat on the inner side of the frame structure, and the baffle is vertically snapped onto the front end of the protective plate.

[0012] The aforementioned protective device for spraying paint on steel structure columns and beams has a groove at one end of the baffle. The baffle and the groove are made of rubber, and the groove is engaged with the edge of the protective plate.

[0013] The beneficial effects of this utility model's protective device for spraying paint on steel structure columns and beams are as follows: This protective tool is applicable to the protection of finished steel structure columns and beams of different sizes. By combining the tools and using an adjuster to adjust the distance between the moving and fixed angle brackets, it ensures a close fit when using different models of steel beams. Adjusting the distance between the telescopic pressure bar and the vertical bar ensures that the protective plate on the top surface is tightly attached to the steel beam. Using a baffle, protection can be provided in the recessed areas of the steel beam. Using a slot to install the baffle facilitates disassembly and assembly while adapting to the internal spaces of different models of steel beams. During spraying, this device effectively protects the finished product. After spraying, it can be promptly disassembled and cleaned, offering advantages such as simple installation and disassembly, good safety, and economy. Attached Figure Description
