Description
Technical field
The utility model is related to Suspension bridge structure, rope net curtain wall construction, beam-string structures, are a kind of novel cable body connection sides
Formula.
Background technology
In existing Suspension bridge structure, rope net curtain wall construction, beam-string structure, main rope and hoist cable (or strut or sunpender) it
Between generally use cast node connect, cast node will be according to main rope, hoist cable (or strut or sunpender) specification, primary and secondary cord clip angle
And stress size is specially designed, cast node is all often single product, can not quantify to produce.Moreover, cast node
To pass through the programs such as finite element analysis, casting in-depth, die sinking, casting, polishing, the process-cycle is long, and project cost is high.
Also individual engineerings substitute cord clip using forging and stamping clamping plate, a pair of of clamping plate is required for being fastened with bolt up and down.But because needing
To continue to employ enough spaces to fastening bolt, connecting node is big, influences beauty.
Utility model content
In order to overcome traditional design to cause using cast node, long in time limit, project cost is high, or forging and stamping node is unsightly etc.
Disadvantage, the utility model design new connection type-rope clamp formula cord clip, feature using steel wire rope folder：Be easy to buying, processing,
Simple installation, period be short, low cost, appearance are beautiful.
The principle of steel wire rope clamp is that two strand steel wire ropes are tightened together by U-bolt and holder, utilizes friction mechanical resistance
The only opposite sliding of steel wire rope even loosens (see 1 steel wire rope clamp of attached drawing).The ingenious work that steel wire rope clamp is utilized of the utility model
Principle and construction, U-bolt is straddled on main rope, puts on holder, T-type part respectively, then with nut by main rope, holder, T-type part
It tightens together.T-type part web holes connect hoist cable (or strut or sunpender) by axis pin.Design be easy to buying, processing,
Simple installation, period be short, low cost novel product, sees attached drawing 2.
Rope clamp formula cord clip only consists of two parts, i.e. two sets of steel wire rope clamps, a T-type part.Rope clamp is upward according to main rope specification
Type selecting nearby, rope clamp GB/T5976《Steel wire rope clamp》Fixed product, is easily purchased；T-type part makes in steel construction processing factory, passes through
Several processes such as Numerical control cutting, welding, drilling, preservative treatment can be completed, and not need especially complex processing.
T-type part steel plate welding processing, the optional Q345B~E of material, web thickness pitch ear according to cable body producer of cable body producer
Value, wing plate thickness determine opening size according to Strength co-mputation nearby downwards.If selecting strut or sunpender (non-hoist cable) in structure,
Web thickness also needs strength check to determine.
See that attached drawing 3, T-type part A values are equal to GB/T5976《Steel wire rope clamp》Middle A values；P values are pressed at main push-towing rope inclination maximum (i.e. most
Close to tower mast) cord clip chosen by geometrical analysis, and rope clamp nut can not be collided with hoist cable (or sunpender or strut)；S, M, N value are
Construct value.In same engineering, A, M, N, S, P can choose definite value, and Q values then will according to main rope and hoist cable (or sunpender, or
Strut) angle determines, it is ensured that and extra bending is not present in main rope at node.T-type part needs to do heavy antisepsis processing, and heat is done in construction
It is zinc-plated.
It is producer's approved product that hoist cable, which pitches ear, and hoist cable specification is identical in general same engineering, and fork ear is also identical.Thus same
T-type part web plate thickness is chosen as unified value in engineering.In same engineering, it is proposed that will be according to the upward value of Strength co-mputation, by T-type
Part wing plate thickness is also set as unified value.
Each cord clip uses two or more rope clamps, and the relative positioning between rope clamp and T-type part earhole is adjusted by design,
To realize that redundancy bending does not occur for main rope.
The utility model has the beneficial effects that the operation principle and construction of steel wire rope clamp is utilized, by the U-shaped of steel wire rope clamp
Bolt straddles on main rope, puts on holder, T-type part respectively, then main rope, holder, T-type part are tightened together with nut.T-type part
Web holes connect hoist cable (or strut or sunpender) by axis pin, start rope clamp formula cord clip.Rope clamp formula cord clip is only by steel wire rope
Folder and T-type part composition, rope clamp is international product, is easy to purchase, and T-type part is that factory's welding is completed.The buying processing of rope clamp formula cord clip
Period is short, low cost, handsome in appearance, simple installation.Suitable for main rope diameter phi 60 and Suspension bridge structure below, rope net curtain wall
In structure, beam-string structure.

Specific implementation mode：
【Embodiment】
The a certain suspension bridge that crosses the river, cable body planar development are shown in Fig. 4.Main rope specification φ 38, hoist cable specification φ 12.Determine steel wire rope
Folder is M40, and rope clamp A values are 69mm, U-bolt M27.It is 22mm, fork ear outer rim half that cable body producer, which provides hoist cable fork ear opening,
Diameter 69mm, it is 16 to choose T-type part web thickness, and strength check determines that T-type part wing plate thickness is 40mm.It is simulated through CAD entities, sees Fig. 5,
It is 51mm, fork ear and rope clamp clearance only 10mm to take P values, and fork ear is not collided with rope clamp, and is unlikely to T-type part being made too
Greatly.
Holder C values are 131mm, take M=40, the wide 149mm of T-type part wing plate, are slightly larger than C values, and holder is opposite with wing plate to be coordinated
It is beautiful.N should be not less than M values, and this case takes 60mm, sees attached drawing 6.
Each point hoist cable and main rope tangent line angle, each T-type part Q values are different, are analyzed according to mechanics scoreboard and determine that Q values are shown in
Fig. 7.
T-type part is in factory process, web full penetration, controls weld reinforcement, it is necessary to when need grinding process, it is ensured that weldering
Seam is not fought with rope clamp nut.Postwelding is by first-order weld UT flaw detections, and corner angle of polishing modify surface, and galvanizing after the completion is handled.
Main rope is tensioned in erecting bed with jack level, is measured each cord clip anchor point, is put on rope clamp U-bolt, T-type part,
Fastening nut.Cord clip will pay special attention to the corner of cord clip and main rope before fixing, this case is by main rope, hoist cable design in approximately the same plane
Interior, when installation, allows cord clip to naturally droop.Hoist cable is hung up after main rope installation, method is simple and practicable.
