Description
Technical field：
The invention belongs to building structure technology field, is related to a kind of strop node of rope bar prestressed steel structure, particularly
A kind of strop node for concave plane rope net.
Background technology：
It by rope, bar is basic Component units that rope bar prestressed structure, which is, pass through prestressing force provide the rigidity of structure one kind it is empty
Between structural system.Rope bar prestressed structure can trace back to famous American architect R.B.Fuller in the 1940s earliest
The tension integral structure of proposition.After Fuller, there are many scholars and engineer again from different angles to such structure
System is analyzed and annotated.The eighties, the B.H.Geiger and M.Levy in the U.S. are further drilled Fuller thought
Become and develop, it is proposed that cable dome structure is simultaneously applied to Practical Project.After the appearance of flexible prestressing structure, numerous engineerings
Technical staff has started the exploration for blending conventional rigid structure and flexible prestressing structure.1993, Japanese law and politics university
Kawaguchi defend professor and propose a kind of hard and soft hybrid spatial form-suspended-dome structure so that prestressed spatial structure
Development and application has reached new height.
Strop is its core component in rope bar prestressed structure, can be connected a series of rod member and prestressed cable by strop
Pick up and, form space entirety stress system, strop node needs to connect the components such as radial cable, ring rope, strut, is in structure
Most important stress joint.The plane form of rope bar prestress system is often based on circular, regular polygon；As architect sets
Meter theory progressively develops, and the irregular form roof system shaped like free form surface is gradually favored by numerous architects, and this also causes
The strop plane configuration of rope bar prestress system gradually develops to randomization, ellipse, irregular polygon progressively occurs
Deng even free curve shape plane cable net.In circular or regular polygon plane form Suo Wangzhong, often strop and radial cable
Or the relative position of oblique cord is relatively more fixed；But for above-mentioned irregular rope net, strop and the relative position of radial cable or oblique cord are but
There is more change.Currently used strop node usually fixes the connection otic placode of radial cable or oblique cord and strop connector
Connection, still using a kind of or limited several strop nodes to reach the requirement that rope net is connected in regular planar rope net,
And joint form traditional in concave plane cable net structure can dramatically increase strop node species, this not only adds strop
Node fabricates difficulty, and is unfavorable for node standardized production, and then adds node processing and manufacturing cost.Therefore, compel
A kind of Novel ring socket point for concave plane rope net will be designed by being essential.
The content of the invention：
The defects of it is an object of the invention to overcome prior art to exist, meeting prestressed spatial structure strop node
On the premise of constructing structure requirement, design provides a kind of Novel ring socket point applied to concave plane rope net.
To achieve these goals, the agent structure of the strop node of the present invention for concave plane rope net includes
Bearing pin connector, oblique cord otic placode, strop connector, montant connection otic placode, bearing pin end plate, countersunk bolt, high-strength bolt, strop rope
Hole and oblique cord connecting hole；Bearing pin connector is made up of bearing pin and bearing pin swivel becket, and bearing pin swivel becket is sleeved on bearing pin, bearing pin end
Plate includes upper pin end plate and lower bearing pin end plate；Bearing pin connector respectively with oblique cord otic placode, strop connector and montant engaging lug
Plate connects；The top and bottom of bearing pin connector set upper pin end plate and lower bearing pin end plate, upper pin end plate and lower pin respectively
Shaft end plate is connected by countersunk bolt with bearing pin, and oblique cord otic placode is fixedly mounted on the lateral surface of bearing pin connector, oblique cord ear
The quantity of plate according to be actually needed determine；Oblique cord connecting hole is provided with oblique cord otic placode, the position of oblique cord connecting hole is according to external oblique
The angle-determining of rope and horizontal plane, oblique cord center line should be made to reduce the unbalanced moment on socket point by the node centre of form；Upper pin
Shaft end plate and lower bearing pin end plate are connected by high-strength bolt with strop connector, and strop connector is led to by strop connecting plate and cover plate
High-strength bolt connection composition is crossed, strop connecting plate is provided with rope hole, and external strop is connected realization through rope hole with strop connector
The purpose of fixed strop；Montant connection otic placode is welded with cover plate, external vertical strut passes through montant connection otic placode and node
It is connected, realizes being articulated and connected for vertical strut and whole node.
During present invention assembling, first bearing pin is connected with the lower bearing pin end plate of bearing pin connector bottom with countersunk bolt, then will
The bearing pin swivel becket for being connected with oblique cord otic placode is inserted in bearing pin, is then connected bearing pin with upper pin end plate with countersunk bolt, finally
Strop connector is fixed with high-strength bolt and upper pin end plate, lower bearing pin end plate connection.
Compared with prior art, its is simple in construction, scientific in principle, easy to operate, and connector is used as by the use of bearing pin by the present invention
Strop, oblique cord otic placode and vertical strut are connected, can arbitrarily change the angle between radial cable and strop, both be applicable to not advise
Then plane cable net, conventional regular planar rope net is more can be applied to, design studies can be standardized, realize standardization system
Make, so as to significantly save strop design of node, processing and manufacturing cost.
