Description

High-strength arc truss structure
Technical field
The present invention relates to construction steel structure, particularly a kind of high-strength arc truss structure.
Background technology
Shaped steel welding production being used conventional arched truss structure, although the belfast truss structure structure being welded using shaped steel more Intensity is high, but has the following disadvantages:1st, traditional truss structure skeleton is that many web members are welded between upper and lower chord member, welding During the complicated production process such as Structure of need combination, welding, weld bond cleaning, Crater antiseptic, structure adjustment, and web member is short Small, welding node is more, and workload is big, low production efficiency.2nd, welding process needs jig, welding machine, bonding wire and supporting electricity A large amount of facilities such as gas and professional welding technique workman, manufacturing cost are high.3rd, framework of glasshouse big shack deformation is big after welding, and adjustment is difficult Degree is big, and overall structure is irregular.4th, the anticorrosive coat of welding destruction skeleton, Crater antiseptic is unable to reach former anti-corrosion function.5th, weld Flue gas causes environmental pollution, and influence producers are healthy.
The content of the invention
The present invention is in order to solve the above-mentioned technical problem can to improve production efficiency, reduction manufacturing cost there is provided one kind, overall Compound with regular structure, reduction weld bond quantity, the high-strength arc truss knot for not influenceing the anti-corrosion function of skeleton, not causing environmental pollution Structure.
The present invention technical solution be:
A kind of high-strength arc truss structure, including arc bar, it is characterised in that:Arc bar outer bottom along its length Multiple connectors are installed with, wherein between the end of the connector correspondence arc bar at two ends, spaced apart two connectors Be removably connected with long chord member and adjacent two long-chord bars formation chi structure, and connector positioned at arc boom end and and its Short chord member is detachably connected between adjacent connector, the short chord member close to the long chord member of arc boom end with intersecting;Mutual Support bar I is removably connected between the intersection and arc bar of two chord members intersected, in each connector and just right with it Chord member between be removably connected with support bar II.
As further preferred, the arc bar is formed by tube bending, and Stability Analysis of Structures implementations are not being reduced to realize Lower mitigation arc bar weight, saves material cost.
As further preferred, the arc bar is formed by angle steel or T-steel bending.
As further preferred, the connector is welded on arc bar.
As further preferred, detachably connected by bolt between the two ends of the long and short chord member and corresponding connector Connect.
As further preferred, contiguous block I, support bar I upper ends are respectively welded at arc bar outer bottom correspondence support bar I It is bolted on contiguous block I, the lower end of support bar 1 is connected between the crosspoint of corresponding two chord members by bolt Connect.
As further preferred, contiguous block II, support bar are respectively welded at correspondence support bar II on each long chord member II upper and lower ends are bolted on corresponding connector and contiguous block II respectively.
As further preferred, the connector positioned at arc boom end is horizontal.
The beneficial effects of the invention are as follows:
1st, because the outer bottom in arc bar is installed with multiple connectors along its length, wherein the connector positioned at two ends Long chord member is removably connected between the end of correspondence arc bar, spaced apart two connectors and two adjacent long-chord rods Short chord member is detachably connected into chi structure, and between the connector and connector adjacent thereto of arc boom end, it is described Short chord member close to the long chord member of arc boom end with intersecting;Therefore simple in construction, overall construction intensity and stability are good, installation side Just, fast, manufacturing cost greatly reduces, the set-up time is shortened, operating efficiency is improved, prevents from causing environmental pollution.
2nd, due to being removably connected with support bar I between the intersection and arc bar of cross one another two chord members, Each connector and with its just to chord member between be removably connected with support bar II;Therefore it further enhancing overall structure strong Degree, can prevent arc bar and long and short chord member flexural deformation or damage that high wind, accumulated snow etc. are caused.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is Fig. 1 partial enlarged drawing.
In figure:1- arc bars, 2- connectors, the long chord members of 3-, the short chord members of 4-, 5- support bars I, 6- support bar II, 7- contiguous block I, 8- contiguous block II.
Embodiment
As depicted in figs. 1 and 2, a kind of high-strength arc truss structure of the present invention, an including arc bar 1, it is described Arc bar 1 is formed by the bending of steel pipe, angle steel or T-steel, and the weight of arc bar 1 is mitigated in the case of structural stability is not reduced to realize Amount, saves material cost.Multiple connectors 2 are welded with along its length in the outer bottom of arc bar 1, wherein the company positioned at two ends The end of the corresponding arc bar 1 of fitting 2 and horizontally disposed, long chord member 3 has been bolted between spaced apart two connectors 2 And adjacent two long chord member 3 formation chi structure, and connector 2 positioned at the end of arc bar 1 and connector 2 adjacent thereto it Between be bolted short chord member 4, the short chord member 4 and the long chord member 3 close to the end of arc bar 1 intersect.
Support bar I5 is bolted between the intersection and arc bar 1 of cross one another two chord members, every Individual connector 2 and with its just to chord member between be bolted support bar II6.In the bottom surface of arc bar 1 correspondence support bar Contiguous block I7 is respectively welded at I5, support bar I5 two ends are bolted on contiguous block I7 and two chord members of correspondence respectively 4 intersection.Contiguous block II8, support bar II6 two ends point are respectively welded at correspondence support bar II6 on each chord member 4 It is not bolted on corresponding connector 3 and contiguous block II8.
The high-strength arc truss structure can be used as light roof supporting construction and use.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited In specific details and shown here as the legend with description.
