Description
Technical field
The utility model relates to bridge engineering and the engineering field of taking precautions against natural calamities, specifically a kind of interim linkage of suspension bridge steel case beam beam section base plate.
Background technology
Suspension bridge is in when construction and close up the back in order to adjust linear needs, and usually at the interim linkage of the intersegmental employing of steel case beam beam, when not needing interim linkage, linkage can be removed.The interim linkage of steel case beam base plate is installed on the base plate of adjacent steel case beam, generally is made up of pull bar and the steel plate framework that is welded on beam section edge, thereby forms a kind of post limbs and be with setting up the beam section.When steel case beam beam section took place in opposite directions with opposing motion, the interim connector that is arranged on the case beam was converted to a power with the moment of flexure of beam section, and is born by the loaded plate that pull bar passes on the steel plate framework.The interim linkage structure of existing suspension bridge steel case beam base plate is as follows: on two adjacent steel case soffits 2 loaded plates are set respectively, two steel case beams link to each other by the pull bar that runs through 4 loaded plates, 2 vertical yoke plates are installed between 2 loaded plates on the steel case beam, its position is in the left and right sides of pull bar respectively, all is equipped with the power transmission nut on the pull bar in the loaded plate outside.Because suspension bridge is generally built in the coastal area, the big internal force of its beam section under strong wind atmosphere may cause the interim linkage of base plate to be damaged or come off, because only at loaded plate outside assembling power transmission nut, loaded plate on each steel case beam all is stressed separately, therefore there is the hypodynamic problem of carrying in the interim linkage of base plate, if under strong wind atmosphere, be damaged, the wind resistance safety of setting up steel case beam beam section will be threatened directly.
Summary of the invention
The purpose of this utility model is in order to solve the hypodynamic technical problem of carrying that the interim linkage of existing suspension bridge steel case beam beam section base plate exists, to provide a kind of supporting capacity the strong interim linkage of suspension bridge steel case beam beam section base plate.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of interim linkage of suspension bridge steel case beam beam section base plate, on two adjacent steel case beam base plates 2 loaded plates are set respectively, two steel case beams link to each other by the pull bar that runs through 4 loaded plates, 2 vertical yoke plates are installed between 2 loaded plates on the steel case beam, its position is in the left and right sides of pull bar respectively, all be equipped with the power transmission nut on the pull bar in the loaded plate outside, it is characterized in that all being equipped with the power transmission nut on the pull bar of described every loaded plate inboard.The power transmission nut is all assembled in both sides inside and outside loaded plate, and it is stressed to make two loaded plates to unite, and has directly improved the bearing capacity of linkage.
As preferably, all be welded with stull between the vertical yoke plate of the described pull bar left and right sides, the stull position is in the intersection of vertical yoke plate and loaded plate inside wall, the stull position also can be in the middle part of vertical yoke plate, vertical yoke plate is subjected to the big moment of flexure that loaded plate applies in the distortion of restriction loaded plate, produced bigger stress in the junction of two plates and concentrated, stull can improve the stressed of vertical yoke plate by the mode that limits its distortion, to improve the total bearing capacity of linkage.
As preferably, the junction of described vertical yoke plate and loaded plate is welded with the rib of putting more energy into, and the rib of putting more energy into can be eliminated vertical yoke plate and concentrate with the stress of loaded plate junction, improves the stress distribution of junction by the mode of reinforcement local stiffness.
Owing to adopted the interim linkage of suspension bridge steel case beam beam section base plate of above-mentioned technical scheme, had novel structure, the advantage that supporting capacity is strong.
Description of drawings
Fig. 1: the structural representation of embodiment of the present utility model.
The specific embodiment
Make a detailed explanation below in conjunction with 1 pair of specific embodiment of the present utility model of accompanying drawing.
The interim linkage of a kind of suspension bridge steel case beam beam section base plate as shown in Figure 1 is provided with 2, two steel casees of 2 loaded plates beam 1 respectively and links to each other by 1 pull bar 5 that runs through 4 loaded plates 2 respectively on two adjacent steel case beam 1 base plates.2 vertical yoke plates 3 all are installed between 2 loaded plates 2 on each steel case beam 1, and the position is in the left and right sides of pull bar 2.All be equipped with power transmission nut 4 on the pull bar 5 in every loaded plate 2 outsides, all be equipped with power transmission nut 8 on the pull bar 5 of every loaded plate 2 inboards.All be welded with stull 6 between the vertical yoke plate 3 of pull bar 5 left and right sides, stull 6 positions are in the intersection of vertical yoke plate 3 and loaded plate 2 inside walls.The junction of vertical yoke plate 3 and loaded plate 2 is welded with the rib 7 of putting more energy into.
When there is relative motion in two steel case beams 1, because on the loaded plate 21, preceding loaded plate 21 produced after the distortion before the effect of inside and outside bilateral power transmission nut 4,8, power can at first be passed to, axle power just can continue to be delivered on the loaded plate 22 of back by pull bar 5, and two loaded plates 2 are just joined together stressed jointly.The interim linkage of above-mentioned base plate has adopted the dual reinforcement measure of the stull 6 and the rib 7 of putting more energy into, vertical yoke plate 3 distortion and stressed improvement are significant, compare original member, under same function power, the member amount of deflection decrease by 55.64%, maximum stress decreases by 41.16%, vertical yoke plate 3 upper stress concentrated areas reduce, integrated stress distributes and improves, and lower stress level helps the lifting of member total bearing capacity, has also strengthened safety factor simultaneously.
The foregoing description only is a this patent embodiment preferably, and for example the position of stull 6 also can be welded on the middle part of vertical yoke plate 3, and the intersection that also can be in vertical yoke plate 3 and loaded plate 2 inside walls is to the zone between the middle part of vertical yoke plate 3.The structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
