Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective structure technology, specifically an explosion-proof unit and explosion-proof wall for industrial plants. Background Technology
[0002] In places where there are leaks of flammable gases or liquids, such as chemical plants, flour mills, and petrochemical plants, especially in flammable and explosive industrial plants, explosion-proof walls are often required for structural protection.
[0003] The existing construction process uses reinforced concrete explosion-proof walls, which have a long construction period, cannot be artificially connected to the beams and columns of the portal steel frame structure, have poor explosion-proof effect at the connection, and are prone to contaminating the surrounding finished steel components when pouring concrete. They are difficult to meet the needs of modern portal steel frame structure industrial plants.
[0004] There is an urgent need to develop a new explosion-proof wall structure to meet the current technical requirements of short cycle, easy connection, and low pollution. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an explosion-proof unit and explosion-proof wall for industrial plants, which solves the problems of long construction period of explosion-proof wall, inability to construct connection with the beams and columns of portal steel frame structure, poor explosion-proof effect at the connection, and easy contamination of surrounding finished steel components when pouring concrete.
[0006] To achieve the above objectives, this utility model provides the following technical solution: First, an explosion-proof unit for an industrial plant includes vertical keels, which are respectively arranged on the left and right sides of the explosion-proof unit. Horizontal keels are fixedly connected to the bottom, top, and middle positions of the two sets of vertical keels. Fireproof rock wool is filled between the vertical and horizontal keels. Each vertical keel includes a vertical main body, a first side wall, and a second side wall. A first explosion-proof plate is fixedly connected between the opposing first side walls of the two sets of vertical keels, and a second explosion-proof plate is fixed between the second side walls. This effectively prevents contamination of surrounding finished steel components during concrete pouring.
[0007] As a further technical solution, the vertical keel is welded and fixed to the horizontal keel.
[0008] As a further technical solution, the vertical keel, the horizontal keel and the first explosion-proof plate are fixed together by self-tapping screws; the vertical keel, the horizontal keel and the second explosion-proof plate are fixed together by self-tapping screws.
[0009] As a further technical solution, the self-tapping screws are inserted 15mm from the edge of the first or second explosion-proof plate, and the installation distance between the two self-tapping screws is 300mm.
[0010] As a further technical solution, the vertical keel is a C-shaped steel with a height of 2400mm, and the distance between the two sets of vertical keels is 1200mm.
[0011] As a further technical solution, the transverse keel is a C-shaped steel with a length of 1200mm, and the distance between the two sets of transverse keels is 1200mm.
[0012] As a further technical solution, both the first and second explosion-proof plates are made of fiber cement composite steel plates with a height of 2400mm, a width of 1200mm, and a thickness of 9.5mm.
[0013] Secondly, an explosion-proof wall for industrial plants is constructed from explosion-proof units. The top and bottom surfaces of the wall are fixed to the upper and lower structural surfaces, respectively; the left and right sides are fixed to the left and right structural steel columns, respectively. The explosion-proof units can be prefabricated, solving the problems of long construction periods and difficult operation in confined work areas. The upper and lower structural surfaces and the left and right structural steel columns are in direct contact with the horizontal and vertical keels, and are fixed in two ways. The welded joints between the horizontal and vertical keels are welded to the upper and lower structural surfaces or the left and right structural steel columns; the remaining contact points are fixed with angle brackets and screws, enhancing the explosion-proof effect at the joints.
[0014] As a further technical solution, the vertical keels of adjacent explosion-proof unit splicing parts are connected back-to-back by welding to form vertical double keels, and the horizontal keels are connected back-to-back by welding to form horizontal double keels.
[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model solves the problems of long construction period and difficult operation due to narrow construction work area by designing a prefabricated explosion-proof unit; the explosion-proof unit is fixed by welding and self-tapping screws, realizing the fabrication connection between the explosion-proof wall and the portal steel frame structure beams and columns, which enhances the explosion-proof effect at the connection; the filling material is fireproof rock wool, which effectively avoids contamination of the surrounding finished steel components when pouring concrete.
[0016] The explosion-proof unit of this invention has the advantages of being lightweight, easy to install and disassemble, and recyclable. After being spliced, installed, and fixed as an explosion-proof wall, it has the ability to resist blast shock waves, limiting the destructive effects of an explosion to outside the workshop, thus meeting the requirements for use in factory workshops.
