A high-strength arc-shaped truss structure which can improve production efficiency, reduce manufacturing cost and decrease welded junction number and is regular in overall structure, free of influences on the anticorrosion function of a framework and free of environment pollution comprises arc-shaped rods, wherein a plurality of connecting pieces are fixedly arranged on the outer bottom faces of the arc-shaped rods in the length direction, the connecting pieces at the two ends correspond to the ends of the arc-shaped rods, a long chord member is detachably connected between every two adjacent connecting pieces arranged in a spaced mode, a crossed structure is formed by every two adjacent long chord members, a short chord member is detachably connected between the connecting piece at the end of each arc-shaped rod and the corresponding adjacent connecting piece, and the short chord members and the long chord members close to the ends of the arc-shaped rods are crossed. A supporting rod I is detachably connected between the crossed point of every two crossed chord members and the corresponding arc-shaped rod, and a supporting rod II is detachably connected between each connecting plate and the corresponding chord member right opposite to the connecting plate.
Description
Technical field
The present invention relates to construction steel structure, particularly a kind of high-strength arc trussed construction.
Background technology
Conventional arched trussed construction many employings shaped steel welding production, although the belfast truss structure structural strength adopting shaped steel to be welded is high, but there is following shortcoming: 1, traditional trussed construction skeleton welds 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 large, and production efficiency is low.2, welding process needs a large amount of facilities such as jig, welding machine, bonding wire and mating electrical and professional solder technology workman, and manufacturing cost is high.3, after welding, framework of glasshouse big shack deformation is large, and adjustment difficulty is large, overall structure irregularity.4, welding destroys the anticorrosive coat of skeleton, and Crater antiseptic cannot reach former anti-corrosion function.5, weld flue gas and cause environment pollution, affect producers healthy.
Summary of the invention
The present invention is to solve the problems of the technologies described above, and provides one can enhance productivity, 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 trussed construction of environment pollution.
Technical solution of the present invention is:
A kind of high-strength arc trussed construction, comprise arc bar, it is characterized in that: be installed with multiple connector along its length at the outer bottom of arc bar, wherein be positioned at the end of the corresponding arc bar of connector at two ends, long-chord bar is removably connected with and adjacent two long-chord bars formation chi structures between spaced apart two connectors, and the short chord member that removably connects between the connector and the connector be adjacent of arc boom end, described short chord member intersects with the long-chord bar near arc boom end; Between the crosspoint place and arc bar of cross one another two chord members, be removably connected with support bar I, each connector and and its just right chord member between be removably connected with support bar II.
As further preferably, described arc bar is formed by tube bending, to realize alleviating arc bar weight not reducing under Stability Analysis of Structures implementations, saves material cost.
As preferred further, described arc bar is bent by angle steel or T-steel to form.
As preferred further, described connector is welded on arc bar.
As further preferably, removably connected by bolt between the two ends of described long and short chord member and corresponding connector.
As further preferably, at arc bar outer bottom, corresponding support bar I place is welded with contiguous block I respectively, and support bar I upper end is bolted on contiguous block I, described support bar 1 lower end with and the crosspoint of corresponding two chord members between be bolted.
As preferred further, on each long-chord bar, corresponding support bar II place is welded with contiguous block II respectively, and the two ends up and down of support bar II are connected on corresponding connector and contiguous block II respectively by bolt.
As preferred further, the connector being positioned at arc boom end is horizontal.
The invention has the beneficial effects as follows:
1, because the outer bottom at arc bar is installed with multiple connector along its length, wherein be positioned at the end of the corresponding arc bar of connector at two ends, long-chord bar is removably connected with and adjacent two long-chord bars formation chi structures between spaced apart two connectors, and the short chord member that removably connects between the connector and the connector be adjacent of arc boom end, described short chord member intersects with the long-chord bar near arc boom end; Therefore structure is simple, and overall construction intensity and good stability are easy for installation, quick, greatly reduce manufacturing cost, shorten the set-up time, improve operating efficiency, prevent from causing environment pollution.
2, owing to being removably connected with support bar I between the crosspoint place and arc bar of cross one another two chord members, each connector and and its just right chord member between be removably connected with support bar II; Therefore further enhancing overall construction intensity, the arc bar that can prevent high wind, accumulated snow etc. from causing 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 trussed construction that the present invention relates to, comprises an arc bar 1, and described arc bar 1 forms by steel pipe, angle steel or T-steel are bending, to realize alleviating arc bar 1 weight not reducing under Stability Analysis of Structures implementations, save material cost.Multiple connector 2 is welded with along its length at the outer bottom of arc bar 1, wherein be positioned at the end of the corresponding arc bar 1 of connector 2 at two ends and horizontal arrangement, long-chord bar 3 is bolted and adjacent two long-chord bars 3 form chi structure between spaced apart two connectors 2, and short chord member 4 has been bolted between the connector 2 and the connector 2 be adjacent of arc bar 1 end, described short chord member 4 intersects with the long-chord bar 3 near arc bar 1 end.
Between the crosspoint place and arc bar 1 of cross one another two chord members, be bolted support bar I5, each connector 2 and and its just right chord member between be bolted support bar II6.At arc bar 1 bottom surface, corresponding support bar I5 place is welded with contiguous block I7 respectively, and support bar I5 two ends are connected on contiguous block I7 and the crosspoint place of corresponding two chord members 4 respectively by bolt.On each chord member 4, corresponding support bar II6 place is welded with contiguous block II8 respectively, and the two ends of support bar II6 are connected on corresponding connector 3 and contiguous block II8 respectively by bolt.
This high-strength arc trussed construction can be used as light roof braced structures and uses.
