Description
Technical field
This utility model relates to construction steel structure, particularly a kind of high-strength arc truss structure.
Background technology
Conventional arched truss structure many employings shaped steel welding production, although adopting the belfast truss structure structural strength that shaped steel is welded high, but have the disadvantage in that 1, tradition truss structure skeleton is to weld many web members between upper and lower chord member, the production process that in welding process, Structure of need combination, welding, weld bond cleaning, Crater antiseptic, structure adjustment etc. are complicated, and web member is short and small, welding node is many, and workload is big, and production efficiency is low.2, welding process needs a large amount of facility such as jig, welding machine, bonding wire and mating electrical and specialty solder technology workman, and manufacturing cost is high.3, after welding, framework of glasshouse big shack deformation is big, and adjustment difficulty is big, and overall structure is irregular.4, welding destroys the anticorrosive coat of skeleton, and Crater antiseptic is unable to reach former anti-corrosion function.5, welding flue gas causes environmental pollution, affects producers healthy.
Utility model content
This utility model is to solve above-mentioned technical problem, it is provided that one can improve production efficiency, reduce manufacturing cost, and overall structure is regular, reduce weld bond quantity, do not affect the anti-corrosion function of skeleton, do not cause the high-strength arc truss structure of environmental pollution.
Technical solution of the present utility model is:
A kind of high-strength arc truss structure, including arc bar, it is characterized in that: the outer bottom at arc bar is installed with multiple connector along its length, wherein it is positioned at the end of the connector correspondence arc bar at two ends, it is removably connected with long-chord bar between spaced apart two connectors and adjacent two long-chord bars form chi structure, and the short chord member that removably connects between the connector and the connector being adjacent of arc boom end, described short chord member intersects with the long-chord bar near arc boom end；Between the intersection and arc bar of cross one another two chord members, be removably connected with support bar I, each connector and and its just to chord member between be removably connected with support bar II.
As it is preferred that, described arc bar is to be formed by tube bending, to realize alleviating arc bar weight under not reducing Stability Analysis of Structures implementations, saves material cost.
As it is preferred that, described arc bar is to be bent by angle steel or T-steel to form.
As it is preferred that, described connector is welded on arc bar.
As it is preferred that, removably connected by bolt between two ends and the corresponding connector of described long and short chord member.
As it is preferred that, be respectively welded contiguous block I, support bar I upper end at arc bar outer bottom correspondence support bar I place and be bolted on contiguous block I, described support bar 1 lower end with and the cross point of corresponding two chord members between be bolted.
As it is preferred that, on each long-chord bar, corresponding support bar II place is respectively welded the two ends up and down of contiguous block II, support bar II respectively through on the connector and the contiguous block II that are bolted to correspondence.
As it is preferred that, the connector being positioned at arc boom end is horizontal.
The beneficial effects of the utility model are:
1, owing to being installed with multiple connector along its length at the outer bottom of arc bar, wherein it is positioned at the end of the connector correspondence arc bar at two ends, it is removably connected with long-chord bar between spaced apart two connectors and adjacent two long-chord bars form chi structure, and the short chord member that removably connects between the connector and the connector being adjacent of arc boom end, described short chord member intersects with the long-chord bar near arc boom end；Therefore simple in construction, overall construction intensity and good stability, easy for installation, quick, manufacturing cost is greatly reduced, shortens the set-up time, improve working performance, it is prevented that cause environmental pollution.
2, owing to being removably connected with support bar I between the intersection of cross one another two chord members and arc bar, each connector and and its just to chord member between be removably connected with support bar II；Therefore further enhancing overall construction intensity, it is possible to prevent arc bar that high wind, accumulated snow etc. causes and long and short chord member flexural deformation or damage.

Fig. 2 is the partial enlarged drawing of Fig. 1.
In figure: 1-arc bar, 2-connector, 3-long-chord bar, the short chord member of 4-, 5-support bar I, 6-support bar II, 7-contiguous block I, 8-contiguous block II.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of high-strength arc truss structure that this utility model relates to, including an arc bar 1, described arc bar 1 is to be bent by steel pipe, angle steel or T-steel to form, to realize alleviating arc bar 1 weight under not reducing Stability Analysis of Structures implementations, save material cost.Outer bottom at arc bar 1 is welded with multiple connector 2 along its length, wherein it is positioned at the end of the corresponding arc bar 1 of connector 2 at two ends and horizontally disposed, it is bolted long-chord bar 3 between spaced apart two connectors 2 and adjacent two long-chord bars 3 form chi structure, and between the connector 2 and the connector 2 being adjacent of arc bar 1 end, it being bolted short chord member 4, described short chord member 4 intersects with the long-chord bar 3 near arc bar 1 end.
Between the intersection and arc bar 1 of cross one another two chord members, be bolted support bar I5, each connector 2 and and its just to chord member between be bolted support bar II6.Contiguous block I7, support bar I5 two ends it are respectively welded respectively through being bolted on contiguous block I7 and the intersection of corresponding two chord members 4 at arc bar 1 bottom surface correspondence support bar I5 place.On each chord member 4, corresponding support bar II6 place is respectively welded contiguous block II8, and the two ends of support bar II6 are respectively through on the connector 3 and the contiguous block II8 that are bolted to correspondence.
This high-strength arc truss structure can be used as light roof supporting construction and uses.
Although embodiment of the present utility model is disclosed as above, but listed utilization that it is not restricted in description and embodiment, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, it is easily achieved other amendment, therefore, under the general concept limited without departing substantially from claim and equivalency range, this utility model is not limited to specific details and shown here as the legend with description.
