Abstract
The utility model relates to a high-strength bolted connection node of a steel structure multi-rod piece, which comprises rod pieces, and a node center pole and is characterized by comprising connection modules, wherein each connection module comprises an internal end plate and an external end plate used in pairs, a node connection plate for connecting the internal end plate with the node center pole, and a rod piece connection plate for connecting the external end plate with the rod piece; the internal end plates are arranged vertically along the periphery of the node center pole; the two ends of the node connection plates are in welded connection with the internal end plates and the node center pole respectively; the two ends of the rod piece connection plates are in welded connection with the external end plates and the end parts of the rod pieces respectively; and the internal end plates are in bolted connection with the external end plates. With the adoption of the design, the node is not required to be subjected to precision casting; welding portions can be accomplished outside a site; the welding quality is ensured; the rod pieces are in bolted connection with the node completely; the node is free from environmental influence; and the on-site mounting efficiency is improved. The rod pieces can be connected as required, and the connection of the rod pieces at different angles can be achieved.
Description
Technical field
The utility model relates to steel building construction field, is specially a kind of many rod members of steel work high-strength bolt connected node.
Background technology
The many rod members of steel work connect many, as rack, net shell and various truss etc., and the standard according to " spatial mesh structure tecnical regulations " JGJ7-2010: pass through mutually welding node, hollow ball node, hub node, cast steel node can be classified as rigid joint.
Wherein, welded hollow spherical joints and tubular joint power transmission are effective, and node rigidity is large, but all need Site Welding, and when installation, local rod member difficulty in place, meanwhile, is affected by the factors such as environment temperature, and welding quality is also not easy to guarantee.The on-the-spot installation of embedded hub node that " the embedded hub node of single-layer lattice shell " JG/T136 provides do not need welding, but hub body diameter only has 100mm-165mm, and node is less than normal, and range of application has certain restriction.Pass through mutually welding node to pipe diameter size and rod member angle, rod member radical has certain limitation.
Summary of the invention
The purpose of this utility model is, provides that a kind of welding quality is guaranteed, operating efficiency is high, connects many rod members connected node of good rigidly.
In order to achieve the above object, the utility model is achieved in that
A kind of many rod members of steel work high-strength bolt connected node; It comprises some rod members and a node center post; Also comprise the link block for connecting rod and node center post, each link block includes the some groups of inside and outside end plates that use in pairs, for connecting inner end plate with the node junction plate of node center post, for being connected the rod member junction plate of outer end plate and rod member; Described inner end plate is along the peripheral vertically layout of node center post, and the two ends of node junction plate are welded to connect with inner end plate, node center post respectively; The two ends of rod member junction plate are welded to connect with outer end plate, Rod end respectively; Between interior outer end plate, be bolted.
For the bonding strength of reinforcing member and rod member junction plate, also comprise head plate: in the time that Rod end is opening, head plate is welded in Rod end opening part so that its end face sealing.
Node junction plate, rod member junction plate, according to the difference of application demand, strength demand, through calculating, can adopt simple shear plate or four-bladed vane.
The utility model adopts above-mentioned design, and node does not need hot investment casting, and welding portion can complete outside the venue, has guaranteed welding quality; Rod member is connected completely with bolts with node, not affected by environment, has improved on-the-spot installation effectiveness.As required, can realize many rod members and connect, can realize the connection of different angles rod member.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model central post part and link block.
Fig. 2 is the structural representation of the utility model rod member part and link block.
Fig. 3 is structural representation of the present utility model.
The specific embodiment
Further illustrate the utility model by specific embodiment below.
As shown in Figure 1, Figure 2 and Figure 3, a kind of many rod members of steel work high-strength bolt connected node; It comprises seven rod members 4 and a node center post 1; Also comprise the link block for connecting rod 4 and node center post 1, each link block includes one group of inside and outside end plate using in pairs 3,7, for connecting inner end plate 3 with the node junction plate 2 of node center post 1, for being connected the rod member junction plate 6 of outer end plate 7 and rod member 4; Described inner end plate 3 is along the peripheral vertically layout of node center post 1, and the two ends of node junction plate 2 are welded to connect with inner end plate 3, node center post respectively; The two ends of rod member junction plate are welded to connect with outer end plate 7, rod member 4 ends respectively; Between interior outer end plate 3,7, connect by bolt 8.
For reinforcing member 4 and the bonding strength of rod member junction plate 6, also comprise head plate 5: in the time that rod member 4 ends are opening, head plate 5 is welded in open-ended the sentencing of rod member 4 and makes its end face sealing.
According to node bending rigidity needs; Node junction plate 2, rod member junction plate 7 can adopt simple shear plate or four-bladed vane to make, and meanwhile, the edge of node junction plate 2, rod member junction plate 7 can cut at an angle so that the rod member 4 with certain inclination angle is installed.
This connected node adopts above-mentioned structure, and its node does not need hot investment casting, and welding portion completes in factory, has guaranteed welding quality.Rod member is connected completely with bolts with node, not affected by environment, has improved on-the-spot installation effectiveness.Design of node more flexibly, more excellent performance, applicability be stronger.Node, under guaranteeing that bolt installing space requires, can be accomplished as far as possible littlely, does not take up room.As required, can realize many rod members and connect, can realize the connection of different angles rod member.
