Description
Technical field
The utility model is related to chord members and web member connecting joint structure, and in particular to a kind of large span truss-like purlin chord member
With the connecting joint structure of web member.
Background technology
Roof purline is important time structural elements in metal building system, is shelved in roofing main structure, thereon generally
It is laid with metal roofing board.Roof purline is primarily subjected to roofing vertical load, also doubles as the flat out of plane constraint tie-rod of main structure sometimes,
Ensure the globality of structure.Usual purlin of the 9m columns away from left and right, using cold-rolled forming section C, Z-type form, economy is good；Work as building
When column is away from more than 12m, cold-rolled forming section C, Z-shaped purline can not need the higher purlin form of bearing capacity at this time by calculating.It passes
On system, welded H section steel, ratio-frequency welding H profile steel or joist, bracket etc. are since its design is ripe and manufacture craft is simply preferred shape
Formula, but seem heavy and uneconomical, construction is inconvenient, particularly when column away from it is larger when（More than 20m）.Steel flanged beam purlin is not
The needs of high-speed railway passenger platform rain cover structure design can be met.
The truss-like purlin structural system come into being makes building more light and handy, simple and direct, efficient, is a kind of novel use
In the empty stomach time structure of long-span roofing system.Truss-like purlin is by winding up, lower edge, web member form, and upper and lower string uses M types
（Or " several " type）Light gauge cold-formed steel shape, web member use welded still pipe, and main economic sex expression is in " empty stomach ".Due to truss
Every meter of weight it is not high with the highlights correlations degree of truss, and the load-bearing capacity of truss is directly proportional to truss depth, utilizes this
Feature, the appropriate height for increasing truss, load-bearing capacity is with regard to that can greatly improve.Correlation experience shows the unit of truss-like purlin
Steel using amount is usually not as good as welded H section steel, the half of ratio-frequency welding H profile steel purlin.
Invention content
The purpose of this utility model is to provide the connecting joint structure of a kind of large span truss-like purlin chord member and web member, can
The making process velocity of truss-like purlin node is effectively improved, and safe and reliable.
Technical solution is used by the utility model：
A kind of connecting joint structure of large span truss-like purlin chord member and web member, it is characterised in that：
Including purlin chord member and two purlin web members, the end bending and the fixation on purlin chord member of two purlin web members
It is fixedly connected after place's overlapping by bolt or self threading pin.
Purlin web member is round steel pipe, and end is flattened and bent, the flattening bending segment docking overlapping of two purlin web members, and
Center setting trepanning, is fixedly connected by bolt or self threading pin.
Purlin web member is T-steel, and end machines away web, edge of a wing bending, the bending edge of a wing docking weight of two purlin web members
It is folded, and trepanning is set in center, it is fixedly connected by bolt or self threading pin.
The utility model has the following advantages：
The utility model can effectively improve truss-like purlin web using the node connection mode of non-solder and be connect with chord member
The speed of application of node can effectively reduce truss-like purlin web and the cost of labor of chord member connecting node construction, so as to promote
Extensive use of the truss-like purlin in reality, and it is safe and reliable.

Specific embodiment
The utility model is described in detail With reference to embodiment.
The connecting node of purlin web member and chord member is typically the weakness of truss-like purlin, general to use the side of being welded to connect
Formula, the utility model is related to a kind of large span truss-like purlin chord member and web member connecting joint structure, including purlin chord member 1
With two purlin web members 2, pass through bolt 3 after the end bending of two purlin web members 2 and bearing's overlapping on purlin chord member 1
Or self threading pin 4 is fixedly connected.
When purlin web member 2 is round steel pipe, end is flattened and is bent, the flattening bending segment docking overlapping of two purlin web members 2,
And trepanning is set in center, it is fixedly connected by bolt 3 or self threading pin 4.
When purlin web member 2 is T-steel, end machines away web, edge of a wing bending, the bending edge of a wing pair of two purlin web members 2
Overlapping is connect, and trepanning is set in center, is fixedly connected by bolt 3 or self threading pin 4.
