Abstract
The utility model provides a kind of spreading connection structure of steel truss, in the vertical pole junction of two fashioned iron segments, a connection piece is set, connector includes a rectangular top plate, and two long sides of top plate are separately connected a riser vertical with top plate, forms the structure that cross section is inverted U；Multiple through-holes are equipped on top plate and riser；The connecting pin of two steel truss segment vertical poles is respectively between two risers of connector both ends insertion connector, the top board undersurface of connector is close to the top surface of vertical pole, connector top plate and riser periphery are welded by weld all around and vertical pole, and are welded in the through-hole on top plate and riser by plug welding and vertical pole.The utility model overcomes existing butt welding connection heavy workload, welding quality is difficult to ensure, and is bolted unworkable problem.
Description
Technical field
The utility model relates to steel truss structures used in architectural engineering, and in particular to one kind is connected by multiple segments
Made of steel truss connection structure.
Background technique
When steel truss is bridge construction through frequently with steel construction, for large span connect or support.Steel truss is logical
It often include at least two vertical poles, vertical pole uses fashioned iron, such as channel steel to make, connected by lateral with diagonal brace between vertical pole.For length
Longer steel truss is spent, for easy to process and transport, multiple truss segments are usually first processed, at the construction field (site) further according to length
It needs to connect multiple truss segments.The double-walled steel jacket box that certain the highway bridge main pier bearing platform constructed such as the applicant uses, by
Big in structure size, bottom slab stress structure uses steel truss, and the vertical pole of truss uses make-up channel steel.Truss adds in factory's segmentation
Work production, it is integral to be transported to joint connection in site.
Truss connection mainly docks the vertical pole end of two truss segments, and common type of attachment has directly welding and spiral shell
It tethers and connects two kinds.Directly welding is by the butt welding of end parts of two vertical poles, and welding workload is big, and the intensity of weld is difficult to ensure；
Being bolted is that connecting plate is arranged in vertical pole end, and two vertical pole ends are connected with by connecting plate, are bolted installation side
Just, bolt is connected when but due to truss use will bear shearing force, will affect the service life of truss, there is also certain safety
Hidden danger.And for the steel truss that vertical pole is process by make-up channel steel, it is bolted place since make-up channel steel inner space is small,
There is also the installation unworkable problems of bolt.
Summary of the invention
The purpose of this utility model is that connect the above problem encountered for the medium-sized steel truss of constructing, providing a kind of can subtract
Small connection difficulty improves the spreading connection structure of the steel truss of connection speed and quality,
The technical solution of the utility model is as follows:
A kind of spreading connection structure of steel truss, the steel truss are formed by connecting by multiple truss segments, each purlin
The vertical pole of frame segment is made of make-up channel steel, it is characterised in that: the vertical pole end of every two segment is connected using connector
It connects, the connector includes a rectangular top plate, and two long sides of the top plate are separately connected a riser vertical with top plate, shape
It is the structure of inverted U at cross section；Spacing between two risers is equal to the width of steel truss vertical pole make-up channel steel；The top plate
With multiple through-holes are equipped on riser；The connecting pin of two steel truss segment vertical poles is respectively from connector both ends insertion connector
Between two risers, the top board undersurface of connector is close to the top surface of vertical pole, and connector top plate and riser periphery pass through weld all around and vertical pole
Welding, and welded in the through-hole on top plate and riser by plug welding and vertical pole.
The utility model carries out the connection of steel truss by special connector, and connector is stuck in the company of two fashioned iron vertical poles
End is connect, is jumped a queue the welding manner of weldering with steel truss vertical pole using weld all around, welding workload is connected compared with normal welding and reduced, cancels
It is bolted, speed of application is fast, and quality of connection is reliable, is particularly suitable for vertical pole and is connected using the spreading between the truss of make-up channel steel
It connects.

Specific embodiment
As shown in Figure 1 and Figure 2, the spreading connection structure of a kind of steel truss provided by the utility model, the steel truss
1 is formed by connecting by multiple truss segments, and the vertical pole 2 of each truss segment is made of make-up channel steel, the vertical pole of every two segment
End is attached using connector 3.
The structure of the connector 3 as shown in figure 3, figure 4 and figure 5, an including rectangular top plate 31, the top plate 31
Two long sides are separately connected a riser 32 vertical with top plate, form the structure that cross section is inverted U；Spacing between two risers 32
Equal to the width of steel truss vertical pole make-up channel steel；Multiple through-holes 33 are equipped on the top plate and riser.
The connecting pin of two steel truss segment vertical poles respectively from 3 both ends of connector insertion connector two risers 32 between,
31 bottom surface of top plate of connector be close to the top surface of steel truss vertical pole 2, connector top plate 31 and 32 periphery of riser by weld all around with
Vertical pole 2 welds, and is welded in the through-hole 33 on top plate and riser by plug welding and vertical pole.
Batter brace bar 4 in Fig. 1 is installed again after the connection of vertical pole 2.
The utility model is when it is implemented, can also be respectively welded one and top along two long sides on the top plate 31 of the connector
The vertical stiffening plate 34 of plate, to enhance the bending resistance of link position.
