Abstract
The utility model discloses a kind of bridge cable body anchoring anchor head, comprise the bearing plate of rectangular configuration, along both sides, long limit vertical symmetry is welded with anchor plate to bearing plate upper surface, between symmetrically arranged anchor plate, interval vertical is welded with multiple gusset plate, the spaced apart through hole be provided with for wearing cable body on bearing plate, anchor plate is corrugated sheet steel, is positioned on the cable body below bearing plate and is arranged with anchor plate and clamp nut successively from top to bottom, and the bonding surface welding of anchor plate and bearing plate is connected.The utility model advantage is that structure is simple, easy for installation, safety factor is high, change the anchor plate of original plane structure into wavy shaped configuration, improve the anti-flexion stiffness of anchor device, make it that cripling distortion not easily occur, reduce the second inner force effect that it connects between structure, increase the service life; The number of minimizing gusset plate, thus reduce weld seam quantity, reduce endurance failure probability, weight is lighter, is more convenient to lifting, and installation location is more accurate.
Description
Technical field
The utility model relates to the bridge technology field of highway and urban road, especially relates to a kind of bridge cable body anchoring anchor head.
Background technology
Suo Liang (or Sarasota) anchorage zone complex structure in bridge construction, stressed concentrated, be one of key position controlling bridge structure safe operation.In current Suo Liang (or Sarasota) anchorage zone anchor head used by material can be divided into steel anchor head and concrete anchor first two; Steel anchor head is compared with concrete anchor head, and force path is clear and definite, and dead load is comparatively light, and lifting is convenient, and can batch production process, the accuracy of manufacture is high, in-site installation accurate positioning, and the structure space of anchorage zone is less, size is more optimized; Therefore, in existing Suo Liang (or Sarasota) anchorage zone, anchor head used mostly is steel anchor head.
In bridge construction, Suo Liang (or Sarasota) anchor structure itself is a region that local stress is large, power transmission is complicated, the huge Suo Li come from cable body transmission will be distributed on girder (or king-post) cross section by it, the stress concentration phenomenon that easy appearance is excessive, therefore, the whether reliable degree of safety being directly connected to whole bridge of cable body anchoring.But current existing bridge cable body steel anchor head, because of steel plate structure form, the reason restrictions such as construction method, be centre that plain plate that some block sizes differ the is welded steel box structure with multiple gusset plate, the plane flexion stiffness of plain plate is less, easy generation cripling, in actual use for preventing plain plate generation cripling, usually number or thickness by increasing gusset plate improve the rigidity of steel anchor head, therefore steel using amount will be caused to increase, weld seam increases, under long-term dynamic load and action of static load, occur that the probability of fatigue failure is higher.
Summary of the invention
It is simple that the utility model object is to provide a kind of structure, the bridge cable body anchoring anchor head that anti-flexion stiffness is high.
For achieving the above object, the utility model can take following technical proposals:
Bridge cable body anchoring anchor head described in the utility model, comprise the bearing plate of rectangular configuration, along both sides, long limit vertical symmetry is welded with anchor plate to described bearing plate upper surface, between described symmetrically arranged anchor plate, interval vertical is welded with multiple gusset plate, the spaced apart through hole be provided with for wearing cable body on described bearing plate, described anchor plate is corrugated sheet steel, be positioned on the described cable body below described bearing plate and be arranged with anchor plate and clamp nut successively from top to bottom, the bonding surface welding of described anchor plate and bearing plate is connected.
Described anchor plate is one deck or the sandwich construction be connected bonded to each other.
The utility model advantage is that structure is simple, and anti-flexion stiffness is high, easy for installation, and safety factor is high.By changing the anchor plate of original plane structure into wavy shaped configuration, substantially increasing the anti-flexion stiffness of anchor device, making it that cripling distortion not easily occur, reducing the second inner force effect that it connects between structure, increase the service life; Decrease the number of gusset plate simultaneously, thus reduce weld seam quantity, reduce endurance failure probability; Reduce the consumption of steel, make weight lighter, be more convenient to lifting, installation location is more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be Fig. 1 be unkitted cable body structural representation.
Detailed description of the invention
As shown in Figure 1, 2, bridge cable body anchoring anchor head described in the utility model, comprise the bearing plate 1 of rectangular configuration, along both sides, long limit vertical symmetry is welded with anchor plate 2 to bearing plate 1 upper surface, between symmetrically arranged anchor plate 2, interval vertical is welded with multiple gusset plate 3, the lower end of gusset plate 3 and bearing plate 1 upper surface vertical welding, form upper shed steel box structure; The spaced apart through hole 5 be provided with for wearing cable body 4 on bearing plate 1; For improving the anti-flexion stiffness of anchor head, reduce the second inner force effect connected between structure, anchor plate 2 is symmetrically arranged corrugated sheet steel, because the anti-flexion stiffness of corrugated sheet steel is high, therefore the consumption of gusset plate 3 can be reduced, weld seam also reduces thereupon, reduces the fatigue failure phenomenon caused because of long-term dynamic load and action of static load.Be positioned on the cable body 4 below described bearing plate 1 and be arranged with anchor plate 6 and clamp nut 7 from top to bottom successively, the bonding surface welding of anchor plate 6 and bearing plate 1 is connected.Anchor plate 6 is one deck or the sandwich construction be connected bonded to each other, and when for sandwich construction, the upper surface being positioned at the anchor plate 6 of the superiors welds mutually with bearing plate 1 soffit and is connected.
Claims (2)
1. a bridge cable body anchoring anchor head, comprise the bearing plate (1) of rectangular configuration, along both sides, long limit vertical symmetry is welded with anchor plate (2) to described bearing plate (1) upper surface, between described symmetrically arranged anchor plate (2), interval vertical is welded with multiple gusset plate (3), at the upper spaced apart through hole (5) be provided with for wearing cable body (4) of described bearing plate (1), it is characterized in that: described anchor plate (2) is corrugated sheet steel, be positioned on the described cable body (4) below described bearing plate (1) and be arranged with anchor plate (6) and clamp nut (7) from top to bottom successively, the bonding surface welding of described anchor plate (6) and bearing plate (1) is connected.
