Abstract
The invention provides an embedded type steel anchor box, and belongs to the technical field of bridge structure design. The embedded type steel anchor box comprises a horizontal steel pulling plate, an anchor bearing plate, a seat plate, an upper force transfer plate, a lower force transfer plate, a rubber plate and a felt. The rubber plate forms a deformation cushion zone between the steel anchor beam and the concrete at the joint surface of the steel and concrete; the horizontal component force of the inhaul cable is maximally suffered by the steel anchor box via the deformation effect of the deformation cushion zone, thereby greatly reducing the horizontal force suffered by the tower wall, thus ensuring the load-bearing safety of the tower columns. The embedded type steel anchor box can be widely applied to the field of engineering design; such an embedded type steel anchor box can be installed in smaller space of tower columns of medium and small scales of cable-stayed bridge; the stress of the concrete tower wall is greatly reduced at the same time. The embedded type steel anchor box makes the structure design more flexible, makes the stress more reasonable, and makes the engineering construction convenient.
Description
Technical field
The invention belongs to bridge structure design technical field, relate to the structure design of a kind of main bearing member of cable stayed bridge, be related specifically to a kind of can the steel anchor beam of Transducers Embedded in Concrete.
Background technology
At present, tower body is the cable stayed bridge of concrete structure, and on tower, drag-line anchorage style mainly adopts steel anchor box anchoring and the anchoring of steel anchor beam.The force-transmission mechanism of steel anchor box anchorage style is that the horizontal component of king-post both sides drag-line is born jointly by the horizontal steel plate of anchor case and king-post, vertical force component is delivered on the concrete of king-post by the shear connector of the vertical steel plate in anchor case both sides, this anchor type major defect is that no small horizontal force shared by tower wall, is enough to make tower wall concrete cracking.The force-transmission mechanism of steel anchor beam anchor type is that the vertical force component of drag-line passes to king-post by the vertical support of steel anchor beam by bracket, when both sides drag-line horizontal component is equal, the horizontal component of drag-line self is born by steel anchor beam completely, when both sides drag-line horizontal component is unequal, the uneven horizontal force of suspension cable finally passes to tower wall by the support frictional resistance under gooseneck or along bridge to the positive stop at two ends, this anchorage style greatly reduces the horizontal force that tower wall bears, but need in tower, have enough spaces to lay steel anchor beam, and need in tower to increase bracket structure, whole bridge tower structure is made to become bulky complex, therefore this anchor type is difficult to realize on middle-size and small-size cable stayed bridge.
Summary of the invention
The invention provides a kind of flush type steel anchor box, this steel anchor box can directly be nuzzled in tower body concrete in advance, anchor-hold on the tower of middle-size and small-size cable stayed bridge.This steel anchor box power transmission is reliable and stable, by felt of draining the oil at steel anchor box and concrete bottom joint pad, other joint sticker rubber plate, form the submissile moding shape buffer strip of steel anchor beam and concrete king-post horizontal direction, the horizontal distortion of steel anchor box under the effect of drag-line horizontal component is absorbed by the deformation buffer band that rubber tile is formed substantially, namely steel anchor beam is consistent without the need to compatibility of deformation with concrete king-post junction, the horizontal component of drag-line is so just made to be born by steel anchor box to greatest extent, also significantly reduce the horizontal force that tower wall bears simultaneously, ensure that the stressed safety of king-post.
Technical scheme of the present invention is:
A kind of flush type steel anchor box, comprises horizontal steel arm-tie, anchor plate, seat board, upper force transmitting board, lower force transmitting board, rubber tile and asphaltic felt.
A kind of flush type steel anchor box, its steel anchor box is divided into agent structure and accessory structure, steel anchor box agent structure has two pieces of horizontal steel arm-ties 1, horizontal steel arm-tie size is determined according to drag-line horizontal component size, two pieces of horizontal steel arm-ties 1 are arranged in parallel, upper force transmitting board 4 and lower force transmitting board 5 are arranged in parallel between two horizontal steel arm-ties, angle is identical with suspension cable angle, anchor plate 2 and upper force transmitting board 4, lower force transmitting board 5 is connected, be arranged vertically with suspension cable, seat board 3 is connected with horizontal steel arm-tie, be arranged in the bottom of steel anchor box, the all connections of steel anchor box main part all adopt welding.
Single steel anchor box accessory structure part places asphaltic felt 7 bottom seat board 3, pastes rubber tile 6 at steel anchor box and other mating face places concrete.
The invention has the beneficial effects as follows that steel anchor beam can prefabrication, be then directly embedded in concrete king-post, this anchor type can be realized in less king-post.Rubber tile is pasted at steel anchor box and concrete mating face (except mating face, bottom), form the deformation buffer band between a steel anchor beam and concrete, by the metamorphosis of deformation buffer band, the horizontal component of drag-line is born to greatest extent by steel anchor box, substantially reduce the horizontal force that tower wall bears, thus ensure that the stressed safety of king-post.The prefabricated property of this flush type steel anchor box is strong, flexible arrangement, simple structure, reliably stressed, the construction applications at middle-size and small-size cable stayed bridge is used widely, has a good application prospect.

Detailed description of the invention
The specific embodiment of the present invention is described in detail below in conjunction with technical scheme and accompanying drawing.
This flush type steel anchor box divides body structure portion and accessory structure part
Steel anchor box main part has two pieces of horizontal steel arm-ties 1, the firm arm-tie size of level is determined according to drag-line horizontal component size, two pieces of horizontal steel arm-ties are arranged in parallel, upper force transmitting board 4, lower force transmitting board 5 are arranged in parallel between horizontal steel arm-tie, and angle is identical with suspension cable angle, and anchor plate 2 is connected with upper force transmitting board 4, lower force transmitting board 5, be arranged vertically with suspension cable, seat board 3 is connected with horizontal steel arm-tie, is arranged in the bottom of whole anchor case, and all connections of steel anchor box main part all adopt welding.
Single steel anchor box appendage places asphaltic felt 7 bottom seat board 3, pastes rubber tile 6 at steel anchor box and other mating face places concrete.
Enter pre-buried for steel anchor box before king-post concreting, then build.
Besides these examples, all make within thought of the present invention and principle amendment, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
