Abstract
The invention provides an anchorage method for a main cable of a suspension bridge. Anchor heads are arranged on the two ends of the main cable of the suspension bridge, wherein the anchor heads are fixedly connected with an anchor by a connecting device; and a preserved hole for penetrating through the two ends of the anchor is formed in the anchor. The anchorage method is characterized in that the connecting device is a tension rod arranged in the preserved holes of the anchor; the two ends, i.e., the front end and the rear end, of the tension rod extend out of the surface of the anchor, wherein the front end of the tension rod is connected with the anchor heads, and the rear end of the tension rod is connected with an anchor bearing plate. The anchorage method for the main cable of the suspension bridge is reliable in anchorage, high in connecting strength, simple in a connecting structure, convenient to construct, specific in stress, low in strength requirements for each connecting member, time-saving and force-saving, capable of greatly reducing the cost and suitable for large-scale application and popularization.
Description
Technical field
The present invention relates to a kind of anchoring process, specifically is a kind of main rope of suspension bridge anchoring process.
Background technology
The main supporting member of suspension bridge is a main push-towing rope, and main push-towing rope normally forms an integral body by the very high steel wire of some tensile strength by the mode that is arranged in parallel, and the two ends of main push-towing rope are through anchorage 5 and basic anchor connection.Because whether the anchoring property of main push-towing rope reliably is directly connected to the safety of suspension bridge, therefore, during the main push-towing rope anchoring, with anchorage 5 sizes do enough big, to guarantee itself and basic bonding strength.Simultaneously main push-towing rope is dispersed through loose cable saddle or diffusing noose and be multiply strand 1; Pass the preformed hole 4 in the anchorage 5; Carry out anchoring in anchorage 5 back,, reduce the pressure of main push-towing rope anchorage 5 to enlarge the contact area of main push-towing rope and anchorage 5; For reducing the influence of 4 pairs of anchorage 5 intensity of preformed hole, the size of preformed hole 4 is as far as possible little.
As shown in Figure 1; The anchoring process of traditional main push-towing rope and anchorage 5 is prestress wire 6 anchoring process; To be connected with anchorage 5 respectively through the strand 1 usefulness multi beam prestress wire of dispersing 6; Its method of attachment is that front end is connected with strand 1 through connector 3, and the rear end is fixing on the back anchor face of anchorage 5 through anchor plate 7 and ground tackle 8.
Because front end connects through connector 3, connector 3 is connected with strand 1 again, this multiple connection, and power transmission is complicated.Each connector requirement of strength is increased, and syndeton is more complicated, construction is more difficult.
Because steel strand 6 are standardization approved products, its maximum functional intensity is a rated value.Therefore in order to ensure bonding strength, the bundle number of steel strand 6 is more.Because anchorage 5 sizes are big, steel strand 6 length are big, cause steel strand 6 degree of disturbing big.
Summary of the invention
The objective of the invention is to: the deficiency to above-mentioned prior art provides a kind of easy row convenient and simple for operation, efficient quick, practical and reliable main rope of suspension bridge anchoring process.
The technical scheme that the present invention adopts is:
A kind of main rope of suspension bridge anchoring process, said main rope of suspension bridge two ends are provided with anchor head, and anchor head is fixedly connected with the anchor ingot through linkage, and the anchor ingot is provided with the preformed hole that runs through its two ends; It is characterized in that: said linkage is arranged on the interior pull bar of preformed hole of anchor ingot, and the two ends of pull bar are all stretched out the anchor ingot surface, are called the front-end and back-end of pull bar, and wherein: the front end of pull bar connects anchor head, the rear end connects anchor plate.
Said pull bar front end is provided with external screw thread, the anchor head rear end is provided with internal thread intermeshing with it.
Said anchor plate is provided with the installing hole of pull bar, and back end of tie rod passes this installing hole, makes anchor plate be adjacent to anchor ingot end face, and the back end of tie rod behind the anchor plate is provided with external screw thread and supporting locking nut thereof.
Be provided with spherical washer between said anchor plate and the locking nut.
The technique effect that the present invention produces is:
Main rope of suspension bridge anchoring process of the present invention, anchoring is reliable, bonding strength is high, simple, the easy construction, stressed clear of syndeton, little for the requirement of strength of each connector, time saving and energy saving, cost significantly reduces, and is applicable to use on a large scale and promote.

The specific embodiment
As shown in Figure 2; The present invention is a kind of main rope of suspension bridge anchoring process; Main rope of suspension bridge is dispersed through loose cable saddle or diffusing noose and is multiply strand 1, and the two ends of strand 1 are provided with anchor head 2, and anchor head 2 is fixedly connected with anchor ingot 5 through linkage; The back anchor face of anchorage 5 is fixedly connected with anchor plate 7, anchor plate 7 is fixed on the concrete foundation again.
Anchor ingot 5 is provided with the preformed hole 4 that runs through its two ends, and linkage of the present invention is arranged on the push-and-pull rod 9 in the preformed hole 4 of anchor ingot 5.The two ends of pull bar 9 are all stretched out anchor ingot 5 surfaces, are called the front-end and back-end of pull bar 9, and wherein: the front end of pull bar 9 connects anchor head 2, the rear end connects anchor plate 7.The structure that is strand 1 of the present invention and anchorage 5 is the same with traditional anchorage style, but because its strand 1 directly is connected with anchorage 5 interior push-and-pull rods 9, makes stressed clear, simple in structure, the easy construction of main push-towing rope.
The rear end that the front end of pull bar 9 is provided with external screw thread, anchor head 2 is provided with internal thread intermeshing with it, thus with the front end of pull bar 9 through being threaded on the anchor head 2, make pull bar 9 and strand 1 be connected to one.
Anchor plate 7 is provided with the installing hole of pull bar 9; The rear end of pull bar 9 is passed this installing hole, is made anchor plate 7 be adjacent to the installation of anchor ingot 5 rear end faces; Pull bar 9 rear ends behind the anchor plate 7 are provided with external screw thread and supporting locking nut 12 thereof; Utilize anchor plate 7 to support, behind the tensile force of assurance pull bar 9, regulate back end nut 12, be that above-mentioned connection is locked.Simultaneously, be provided with spherical washer between anchor plate 7 and the locking nut 12, what make locking nut 12 and pull bar 9 rear end screw threads cooperates, realizes length adjustment and fastening, promptly makes adjustable positions between locking nut 12 and the anchor plate 7 (anchor ingot 5).This spherical washer is 2 supporting Internal Spherical Surface packing rings 10 and spherical outside surface packing ring 11, can realize the rotation of pull bar 9, prevents to install the bending that just do not causing pull bar 9, influences safety.
