Abstract
The utility model discloses an individual layer net shell bolted connection node is including the node body, conical head or shrouding, high strength bolt and nut. The node body is opened there are a plurality of bolt holes, it has two round holes from top to bottom to open on conical head or the shrouding, high strength bolt's screw rod is divided into big screw section, polygon section and little screw section from nut to another end in proper order. This node has that construction convenience, atress are equitable, the easy advantage such as assurance of quality.
Description
Technical field
Patent of the present invention relates to the connection node of spatial mesh structure, belongs to construction steel structure field.
Background technology
One of principal mode as large span spatial structure, single-layer lattice shell is widely applied, and its most commonly used joint form is welded spherical node.But welded spherical node net shell needs Site Welding, the loaded down with trivial details and weldquality of constructing not easily ensures, does not meet the development trend of building industrialization.Bolt connection node does not need Site Welding, it is only necessary to tights a bolt and is attached, and the duration is fast and construction quality is prone to ensure, meets the requirement of building industrialization.Bolt connection node is widely applied in two layer of space network, but application is seldom in single-layer lattice shell, trace it to its cause, traditional bolted spherical node only has single bolt connecting rod and bolt sphere, its mechanical model is close to hinged, and single-layer lattice shell should adopt the node that bending resistance is bigger, simultaneously traditional bolted spherical node there is also the shortcoming that " false twist " etc. affects construction quality.It is therefore proposed that the node of a kind of easy construction, good mechanical performance will promote the industrialization development process of single-layer lattice shell.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is proposed to a kind of easy construction, reasonable stress, quality are prone to the single-layer lattice shell assembling type node ensured, it only need to carry out bolt connection at the scene, it is not necessary to welding, meet the development trend of building industrialization.
Technical scheme is as follows:
A kind of single-layer lattice shell bolt connection node, including node body, conehead or shrouding, high-strength bolt and nut.Described node body has some bolts hole；Described conehead or shrouding have upper and lower two circular holes；The screw rod of described high-strength bolt is divided into major thread section, polygon section and minor thread section from nut to another termination；Described nut and high-strength bolt major thread section match, and the bolt hole of described node body and the minor thread section of corresponding high-strength bolt match；Described conehead or shrouding and node body are connected by high-strength bolt and nut, and described conehead or shrouding and net shell rod member weld.
The major thread section of described high-strength bolt screw rod and the hand of spiral of minor thread section are contrary.
Circularhole diameter 0.5-2mm bigger than the big footpath of corresponding high-strength bolt major thread section on described conehead and shrouding.
Described nut quantity is one or two for each high-strength bolt.
Beneficial effects of the present invention:
Site operation is convenient and construction quality is prone to ensure: conehead or shrouding are at factory and steel-pipe welding, and scene only needs bolt is screwed into node body, then fastening nut, quick for installation and be prone to remove and reuse；Reasonable stress: node can be assumed that as hinged in net shell plane, out-of-plane bending rigidity is bigger, rod end axle power dough-making powder Moments is undertaken by the tension and compression of upper and lower two high-strength bolts, when high-strength bolt tension, by the extruding of nut and conehead or shrouding, pulling force is passed to screw rod, when high-strength bolt pressurized, by the extruding of nut and conehead or shrouding, pressure is passed to screw rod.

Detailed description of the invention
Embodiment one:
As depicted in figs. 1 and 2, a kind of single-layer lattice shell bolt connection node, including node body 1, conehead 5 or shrouding 4, high-strength bolt 6 and nut 7.This example interior joint body 1 global shape is six terrace with edges, and the angle of each faceted pebble is determined according to the space angle of node linked member, and the bolt hole axis of each faceted pebble is perpendicular to this faceted pebble；Conehead 5 or shrouding 4 have upper and lower two circular holes；The screw rod of high-strength bolt 6 is divided into major thread section, regular hexagon section and minor thread section from nut to another termination；Nut 7 and high-strength bolt 6 major thread section match, and the bolt hole of node body 1 and the minor thread section of corresponding high-strength bolt 6 match；Conehead 5 or shrouding 4 and node body 1 are connected by high-strength bolt 6 and nut 7, and conehead 5 and net shell rod member 3 weld, and shrouding 4 and net shell rod member 2 weld.In the present embodiment, net shell rod member is rectangular steel pipe, and a nut joined by each high-strength bolt.
Construction installation method: (1) first makes each parts of node and net shell rod member in factory process；(2) by high-strength bolt 6 through corresponding conehead 5 or shrouding 4 circular hole, nut 7 is screwed into the major thread section of high-strength bolt 6, by conehead 5 or shrouding 4 and corresponding steel-pipe welding；(3) during in-site installation, the minor thread section of high-strength bolt 6 is screwed in the corresponding bolt hole of node body 1 by the polygon section first rotating high-strength bolt 6, until polygon section and node body 1 hold out against, then to nut direction rotating nut 7, until nut 7 and conehead 5 or shrouding 4 hold out against.
Claims (4)
1. a single-layer lattice shell bolt connection node, including node body, conehead or shrouding, high-strength bolt and nut, it is characterised in that described node body has some bolts hole；Described conehead or shrouding have upper and lower two circular holes；The screw rod of described high-strength bolt is divided into major thread section, polygon section and minor thread section from nut to another termination；Described nut and high-strength bolt major thread section match, and the bolt hole of described node body and the minor thread section of corresponding high-strength bolt match；Described conehead or shrouding and node body are connected by high-strength bolt and nut, and described conehead or shrouding and net shell rod member weld.
2. a kind of single-layer lattice shell bolt connection node according to claim 1, it is characterised in that: the major thread section of described high-strength bolt screw rod and the hand of spiral of minor thread section are contrary.
