Description
Technical field
The utility model relates to a kind of space truss structure of architectural space form of structure.
Background technology
Space truss structure architectural be a kind of very outstanding space structures form, but have from heavy and light, can be used for characteristics such as large span bidirectional stress, at home and abroad used in a large number.Generally speaking, the upper chord of space truss structure, lower chord and web member three form the integral body of a space-load by node, and two kinds of types of attachment are mainly adopted in the connection between the rack member, and a kind of is that the bolted spherical node method connects, and a kind of is that the welded spherical node method connects.
The bolted spherical node method connects the main flow joint form as space truss structure, is widely used in the various space truss structures.Yet there is the relatively poor shortcoming of aesthetic property in the space truss structure that the bolted spherical node method connects and composes, when space truss structure is winded up transparent materials such as adopting glass during as building coats, with need to arrange rest on the bolted spherical node that is connected that winds up, set up purlin at rest then and could connect building coats materials such as glass, thereby make the rack upper strata comparatively complicated, increase height and the weight of space truss structure, had a strong impact on architectural effect.
It is the connected mode of another space truss structure that the welded spherical node method connects, except having with the bolted spherical node method is connected the same shortcoming, the space truss structure that the welded spherical node method connects and composes is installed at the scene also needs a large amount of high-altitude weld jobs, the safety of structure and the level that just depends on the welder to a great extent attractive in appearance thus, and welding procedure itself consuming time, take material, economy is relatively poor.
No matter be that the bolted spherical node method connects or the member of the space truss structure that the welded spherical node method connects and composes can only adopt pipe usually, this has also caused two problems: at first it has lost flexibility in appearance; Secondly structurally the pipe axial carrying capacity is very strong, but bending resistance is not good.Because the circular structure of chord member has caused directly fixed building surface layer, must establish purlin in addition and come not only to have raised cost for the fixed building surface layer on rack winds up node, and increase height and the weight of space truss structure.
Therefore, how purlin is not set in space truss structure, upper chord directly fixed building surface layer becomes problem demanding prompt solution.
The utility model content
The purpose of this utility model is to provide a kind of space truss structure, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
A kind of space truss structure that the utility model provides comprises: complex root has chord member and the node of head plate, it is characterized in that: also comprise a plurality of threaded fasteners; Chord member is that cross section is the hollow stem of rectangle; Intra-node has cavity, the operating space that provides threaded fasteners that head plate is fixedlyed connected with node; The connection surface configuration unanimity that the fixedly connected connection surface configuration of head plate is fixedly connected with corresponding node.
In addition, a kind of space truss structure that the utility model provides can also have following feature: cavity is cylindrical, stiffening rib is set in cylindrical.
In addition, a kind of space truss structure that the utility model provides can also have following feature: the connection surface configuration is the plane.
Further, a kind of space truss structure that the utility model provides can also have following feature: space truss structure also comprises a plurality of web members, and web member and node are connected and a kind of connection during the welded spherical node method is connected for the bolted spherical node method.
Utility model effect and effect
The space truss structure that provides according to the utility model, because this space truss structure has the hollow chord member that cross section is rectangle, both can bear axial force, and can bear the internode moment of flexure that roof panel causes again, space truss structure need not to arrange rest and purlin again, so, the building roof plate can directly be supported on the plane of rack chord member formation, and architectural effect is brief more lucid and lively, and steel using amount is comparatively saved, and need not welding during on-the-spot the installation, time saving and energy saving.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to set forth further.
Embodiment
Fig. 1 is the utility model space truss structure schematic diagram in embodiment one.
Fig. 2 is the vertical view of Fig. 1.
As depicted in figs. 1 and 2, this space truss structure has web member 4, node 8 and eight interior hexagonal high-strength bolts 7 formations of bolt by four 3, four of upper chords with head plate 5.
Node 8 is made up of hemisphere 1 and cylinder 2.Be provided with to the quartering screwed hole that the bolt with web member 4 matches on the hemisphere 1.Cylinder 2 inside have a tubular cavity, and the space of hexagonal high-strength bolt 7 in the operation is provided.Cylinder 2 arranges two through holes, totally eight through holes up and down on each position of halving corresponding with the screwed hole of quartering setting.The openend of cylinder 2 is provided with stiffening rib 6, improves the stress characteristic of node 8.
Four web members 4 are fixedlyed connected with four screwed hole on the hemisphere 1 of node 8 respectively by bolt, and identical with the node connected mode with web member in the existing space truss structure, namely the bolted spherical node method connects.
Every upper chord 3 both can bear axial force for cross section is the hollow stem of rectangle, can bear the internode moment of flexure that roof panel causes again.Each end face of upper chord 3 has head plate 5, and the connection surface configuration that the cylinder of head plate 5 and node 82 is fixedly connected and the profile of cylinder 2 are consistent, and namely the connection surface configuration of head plate 5 is one section identical circular arc of cylinder 2 radiuses.Two screwed holes are arranged above the head plate 5, two lead to the hole site on the cylinder 2 of the position of screwed hole and node 8 on certain position of halving are consistent, and the position of screwed hole makes four upper chords 3 with after node 8 is fixedlyed connected, and a face of four upper chords 3 is in a plane; Screwed hole and interior hexagonal high-strength bolt 7 match.
Every upper chord 3 passes through hole on the cylinder 2 of node 8 by two interior hexagonal high-strength bolts 7 respectively, and the cavity by cylinder 2 is screwed into the screwed hole on the head plate 5, realizes that upper chord 3 fixedlys connected with node 8.Adopt two interior hexagonal high-strength bolts 7 to fix and to prevent the axial rotation of upper chord 3 distaffs, and increase bonding strength.And after fixing, four upper chords 3 are with after node 8 is fixedlyed connected, and a face of four upper chords 3 is in a plane.
