Description
Technical field
The utility model relates to building field more particularly to a kind of concrete-filled steel tube truss-armoured concrete slab combination knots
Structure.
Background technique
It is lightweight, high-strength and greatly across the trend for being modern architecture.Tubular truss is because of its efficient power transmission mechanism and good economy
Benefit and architectural effect, and in ocean engineering, science of bridge building, public building, such as stadiums, conference centre, exhibition center, machine
It is widely applied in field terminal etc. and the structures such as overpass, Urban Landscape Bridge.But greatly across, large space,
In the requirement of the large scales such as Super High, stability, bending stiffness and the torsional rigidity of empty steel pipe truss are insufficient, examine for needs
Consider the large span roof structure of larger negative sense wind action, common empty steel pipe truss structures need more constructions to guarantee to tie
The wind resisting stability of structure.Therefore, engineers and technicians need a kind of concrete-filled steel tube truss-armored concrete board combining structure,
Improve the building performance of large-span structure.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of concrete-filled steel tube truss-is provided
Armored concrete board combining structure, to improve the building performance of large-span structure.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of concrete-filled steel tube truss-reinforcing bar
Concrete slab composite structure, including be made of concrete-filled steel tube truss, armoured concrete slab；The armoured concrete slab pours paving
It is located on concrete-filled steel tube truss, forms the truss stress system of completion；The concrete-filled steel tube truss include top boom, under
Chord member, diagonal web member peace joining beam；The skeleton of two top booms and a lower boom composition triangular truss system, wherein on
Chord member and lower boom are concrete filled steel tube bar；Fixation is attached by lateral bar between the top boom；The top boom with
Fixation is attached by diagonal web member between lower boom, diagonal web member and lateral bar form triangular truss, along the elongated cloth of top boom
It sets, forms complete girder system.
Preferably, the lateral bar and diagonal web member are sky steel tube member bar.
Preferably, the rod size of the lower boom is greater than the size of top boom.
The beneficial effects of the utility model are: the utility model improves in addition to that can improve node strength and anti-fatigue performance
Fire resistance, except saving steel, the overall stability of structure and local stability can obtain biggish improvement；For
Need to consider the large span roof structure of larger negative sense wind action, the self weight of the utility model concrete filled can be mentioned effectively
Its high wind resisting stability, to directly weaken the problem of wind force proofing design；For turn of Staggered Truss Structure Systems and skyscraper
Layer is changed, the pipe-line equipments such as communication, water power can be laid with using its empty stomach part, to reduce layer height, to reduce total cost, is used
Concrete-filled steel tube truss conversion layer can reduce local quality than beam-type transition layer and concentrate, conducive to the smooth transition of the rigidity of structure.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.

Wherein, 1 is concrete-filled steel tube truss, and 1-1 is top boom, and 1-2 is lower boom, and 1-3 is diagonal web member, and 1-4 is lateral
Bar, 2 be armoured concrete slab.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figs. 1-2, a kind of concrete-filled steel tube truss-armored concrete board combining structure, the structure is mainly by steel pipe
Concrete truss 1, armoured concrete slab 2 form；Armoured concrete slab 2, which pours, to be laid on concrete-filled steel tube truss 1, has been formed
At truss stress system；Concrete-filled steel tube truss 1 includes top boom 1-1, lower boom 1-2, diagonal web member 1-3 peace joining beam
1-4；A two top boom 1-1 and lower boom 1-2 form the skeleton of triangular truss system, wherein top boom 1-1 and lower edge
Bar 1-2 is concrete filled steel tube bar；Fixation is attached by lateral bar 1-4 between top boom 1-1；Top boom 1-1 and lower boom
Fixation is attached by diagonal web member 1-3 between 1-2, diagonal web member 1-3 and lateral bar 1-4 form triangular truss, along top boom
The elongated arrangement of 1-1, forms complete girder system.
In specific implementation, lateral bar 1-4 and diagonal web member 1-3 are sky steel tube member bar.
In specific implementation, the rod size of lower boom 1-2 is greater than the size of top boom 1-1.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
