Abstract
The utility model relates to a hub bell-and-spigot node for a triangular lattice steel latticed shell, which is composed of a node part, a cover plate, a screw bolt, a screw cap, a spring shim, and a bell-and-spigot rod, wherein, two end surfaces of the node part form plane surfaces; after the bell-and-spigot rod is inserted in a slot of the node, the cover plate and the node part are of plane junction; a fringe node of the steel latticed shell is formed by the method that a processed steel sheet and the node are welded with each other by a special mould for welding.
Description
The utility model is the node about steel screen, particularly about having the node of triangular mesh steel screen.
The top cover of the present various major diameter storage tanks of China generally adopts on-the-spot method to welding to connect.There are many deficiencys in the method that this traditional field welding connects.After problems of welded quality, welding, the internal stress of weld seam is bigger, easily cracking.Secondly, must there be the electric power and the welding equipment of enough capacity the job site.Now, along with expanding economy, desired storage tank list tankage size constantly enlarges, single jar of diameter is during greater than 32 meters, single top cover of irritating if adopt conventional design to become board-like or rib of slab formula structure, obviously reaches requirement at stress performance and material consumption and preparation process etc.So in large-scale single top ends of cans design, be used to connect and the processing method of fixed roof and technology Gonna breakthrough, development.In recent years, the space single-layer lattice shell because of characteristics such as its stress performance are good, attractive in appearance, had obtained being extensive use of.Particularly the parts of its node and rod member are all less, are convenient to production and processing and construction arrangement.But its end face of node commonly used is at present made complicated, and processing cost is higher, and the operation difficulty of construction is big, and productivity is lower, applies to be under some influence.
The purpose of this utility model is to provide a kind of triangular mesh steel mesh shell hub type spigot and socket type node, it does not need welding, just can realize the connection of single each pole of top ends of cans easily, the various shortcomings that it can avoid above-mentioned field welding to cause, while is easy operating again, and cost is lower.
The purpose of this utility model is achieved in that a kind of triangular mesh steel mesh shell hub type spigot and socket type node, it includes node part, node cover plate, bolt, nut, compression spring and spigot and socket type rod member, it is characterized in that: its two ends of described node part are the plane, its hub shape spigot and socket type slotted eye angle perforate in accordance with regulations; Described cover plate and node part are plane engagement, and the fringe node of described steel screen is to be welded by the weld mold and the manufactured node of three blocks of manufactured steel plates by special use.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is node part end face signal of the present utility model.
Fig. 3 is fringe node structural representation of the present utility model.
Embodiment 1, a kind of structure of the present utility model as shown in Figure 1, it comprises bolt 6, nut 5, compression spring 4, cover plate 3, node part 1, spigot and socket type rod member 2.The node method of processing parts has machining and precision casting; Machining is by round steel blanking, lathe cutting, drilling machine boring, and four steps of milling machine groove milling finish, and precision is raised and made is that the casting of node part by one-step is formed.The spigot and socket type rod member is to form the rod end embedded piece by i shaped steel (or steel pipe) and smart casting to be welded.In installation process, as long as the spigot and socket type rod member is inserted in the node hub shape spigot and socket type slotted eye, cover plate 3 is a plane engagement with node part 1 two ends, combines with compression spring 4, bolt 6, nut 5 then.
Embodiment 2: edge contact of the present utility model as shown in Figure 3, it contains steel plate 7, steel plate 8, steel plate 9 and node part 1 ' and is welded, it welds with manufactured node mutually by processing the weld mold of block plate by special use.
The utility model saves land as long as rod member one is saved one in large diameter single top ends of cans processing Insert in the above-mentioned node, just can realize easily the triangular mesh of steel screen Connect. Save original a large amount of Site Welding work, plane node engages simultaneously, again Greatly alleviated the labour intensity of installing, the reduction of erection time, construction cost effectively reduces. The institute With, the utility model is easily manufactured, and with low cost.
Claims (2)
1, a kind of triangular mesh steel mesh shell hub type spigot and socket type node, it includes node part, node cover plate, bolt, nut, compression spring and spigot and socket type rod member and forms, it is characterized in that: node part both ends of the surface are the plane, and the slotted eye and the rod end of its hub shape spigot and socket type are complementary.
2, according to the described node of claim 1, it is characterized in that: node part two ends and node cover plate mating face are the plane.
