The connection structure form of material, attachment strap and abutment and attachment strap and roadbed also has relationship.In consideration of it, solving abutment and attachment strap junction
Problem of Cracking have huge social effect.
Summary of the invention
In order to solve the problems, such as abutment and attachment strap, attachment strap and roadbed junction pavement cracking and destroy, the utility model is mentioned
The embed-type UHPC lap slab of bridge construction of multistage fixed for oblique anchor pole.
A kind of technical solution of the utility model is a kind of embed-type UHPC lap slab of bridge structure of multistage fixed with oblique anchor pole
Make, including the lap slab of bridge that abutment is connected with abutment, attachment strap is laid with by multistage is prefabricated, two attachment strap junctions and attachment strap with
Roadbed junction is provided with sleeper beam, and two layers of TGXG is provided with above attachment strap and roadbed junction, is to banket above attachment strap, fills out
It is road surface on soil, attachment strap and abutment junction are provided with bracket, bracket and abutment one-piece casting, with oblique anchor between bracket and attachment strap
Bar connection.
Further, it is formed close to Abutment attachment strap by UHPC is prefabricated, other attachment straps are formed by normal concrete is prefabricated.
Further, the sleeper beam of setting is concave character type.
Further, the material of oblique anchor pole is stainless steel.
Further, the position that oblique anchor pole is stretched out at bracket is bracket upper side plane.
Further, the gradient that attachment strap is laid with is 2%-8%, and high close to abutment side.
It is connected in a manner of oblique anchor pole between abutment and attachment strap, the presence of oblique anchor pole can reinforce the entirety of attachment strap and abutment
Property, attachment strap can greatly enhance attachment strap in the mechanical properties such as the shearing resistance of bracket junction, reinforcement structure durability using UHPC.Attachment strap
Multistage design main purpose be to reduce adjacent sedimentation difference at two sections, can effectively inhibit the generation of pavement crack.Sleeper beam
It is designed to that concave character type is the straight skidding of attachment strap in order to prevent.Simultaneously as it is opposite smaller by shearing far from abutment side attachment strap, from
Economic aspect considers, using normal concrete attachment strap.
Compared with prior art, the utility model has the following beneficial effects:
(1) pavement crack of abutment Yu attachment strap and attachment strap and road surface junction has been prevented.
(2) durability of attachment strap is enhanced, later maintenance investment significantly reduces, and structure is safe and reliable.
(3) mechanical properties such as shearing resistance of attachment strap are significantly increased, and the diseases such as attachment strap fracture effectively reduce.
(4) it effectively prevent being detached between attachment strap and abutment.
Detailed description of the invention
It is that the technical solution of the utility model is described in conjunction with attached drawing below, attached drawing is only used for showing specific implementation
The purpose of example, and it is not considered as limitations of the present invention.
Fig. 1 is a kind of embed-type UHPC lap slab of bridge organigram of the multistage fixed with oblique anchor pole.
1 UHPC attachment strap in figure, 2 oblique anchor poles, 3 abutments, 4 brackets, 5 sleeper beams, 6 TGXG, 7 road surfaces, 8 normal concretes
Attachment strap.
Specific embodiment
Specifically describing the embodiments of the present invention with reference to the accompanying drawing, wherein attached drawing constitutes part of this application,
And it is used to illustrate the principles of the present invention together with the embodiments of the present invention.
A kind of embed-type UHPC lap slab of bridge of multistage fixed with oblique anchor pole constructs the construction of the present embodiment as shown in Figure 1:,
Including the lap slab of bridge 1 that abutment 3 is connected with abutment 3, attachment strap is laid with by multistage is prefabricated, two attachment strap junctions and attachment strap with
8 roadbed junctions are provided with sleeper beam 5, and two layers of TGXG 6 is provided with above attachment strap 8 and roadbed junction, are to fill out above attachment strap
Soil, banket on for road surface 7, attachment strap 1 and 3 junction of abutment are provided with bracket 4, bracket 4 and 3 one-piece casting of abutment, 4 He of bracket
It is connected between attachment strap 1 with oblique anchor pole 2.
In the present embodiment, it is formed close to Abutment attachment strap 1 by UHPC is prefabricated, other attachment straps 8 are prefabricated by normal concrete
