Description
Technical field
The present invention relates to technical field of bridge engineering, in particular to the structure linkage section of a kind of segment assembled pier stud and its
Design method, construction method.
Background technique
In municipal traffic engineering and railway engineering, design, production and the construction of segment assembled beam are more mature, existing
The beam method processed such as some long line methods, short line casting has been widely used in the construction of size bridge, and bridge pier column is with cast-in-place construction
Cause the whole bridge construction completion time of project tediously long based on mode, is to realize one of fabricated important obstruction of full-bridge, limits assembled
The performance of structural advantage.Integral prefabricated pier stud is a kind of engineer application form for realizing that pier stud is prefabricated assembled, but this method is deposited
Construction weight is big, size and volume are big, the outstanding problems such as limited by transporting, lifting.Segment assembled pier stud (PSBC), will
The segmented prefabrication and assembly construction of pier stud can significantly reduce the weight and size of prefabricated components.
For pier stud as main lateral resistant member, anti-seismic performance is to evaluate a key index of pier stud assembled technology.
Existing segment assembled pier stud (PSBC) mainly uses two kinds of combination assembling forms based on stem grafting seam connection between segment:
The first is the segment assembled pier stud of prestressing force connection, and each segment is only leaned on through full pier stud in vitro or in vivo
Deformed bar connection, it is discontinuous that muscle is indulged in each segment.Stress, deformation and the injury characteristic of this segment assembled pier stud are the same as cast-in-place
There is very big difference in pier stud.Under geological process, it is small that configuration deformed bar leads to residual deformation after small shake, but lacks continuous
Vertical muscle cause whole energy dissipation capacity poor, destroying is in brittleness, therefore is not suitable for the application in middle and high earthquake intensity area.
Another segment assembled pier stud is aided with the energy consumption muscle material such as vertical muscle, each segment to improve anti-seismic performance between segment
Between mainly using grout sleeve connect.A kind of this segment assembled pier stud, each segment both ends of pier stud are both needed to pre-buried multiple grouting
Sleeve, and grout hole and slurry outlet are reserved for each grout sleeve, it is perfused using dedicated grouting material.Grout sleeve with it is dedicated
The price of grouting material is higher, and grouting construction is relatively complicated, and with increasing for joint face, connection is increased with material price, when construction
Between extend, it is serious to limit the engineering application value of the segment assembled pier stud using this method.
Summary of the invention
It is an object of the invention to overcome the above-mentioned deficiency in the presence of the prior art, a kind of segment assembled pier stud is provided
Structure linkage section and its design method, construction method, can reduce construction cost and difficulty, further improve component standard
Change, preferably carries out industrialized mass production.
In order to achieve the above-mentioned object of the invention, the present invention provides following technical schemes:
A kind of structure linkage section of segment assembled pier stud, including public segment and parent segment；

Described first assembled end and the second assembled end are equipped with the first annular recess, third assembly end and the 4th assembly
It holds and is equipped with the second annular recess, the shape size of first annular recess and the second annular recess is identical.
More for prefabricated subsection assembled pier stud seam, vertical muscle is difficult to elongated arrangement, and then influences economy and practicability
Etc. practical problems, prefabricated subsection is designed as two class standard segments, the first kind is with vertical muscles and joints-vital links in a speech section (public segment), and second is
It connects segment (parent segment).The vertical muscle of the first of public segment stretches out, and general without setting crotch, the first vertical muscle protrudes into the perforation of parent segment
In hole, and carry out slip casting connection.One parent segment can connect two public segments up and down, be saved by designing male segment and mother
Section, it can be achieved that the vertical muscle mechanical property of segment assembled pier stud it is continuous, and without grout sleeve or slurry anchor, significantly reduce
The difficulty of construction and cost of seam crossing are reduced because segmentation bring connects difficulty.Further, in public segment and parent segment
Contact surface on set concrete shear key, while improving shear behavior, realize the positioning and limit in installation process.Segment
The first annular groove and second annular groove and sealing material being arranged at seam are used cooperatively, and improve intersegmental sealing
Performance meets the requirement of durability of pier column.
Meanwhile the public segment and parent segment be a part of pillarwork, meets corresponding structural strength, rigidity

Logical hole provides one to the vertical muscle to be connected and binding material and reliably constrains bad border, offsets vertical muscle without crotch to cohering
The reduction of slip property.It penetrates through hole and parent segment length is isometric, opening is big, the corresponding minimum of various sizes of vertical muscle coheres length
Degree does not play control action in the design, it can be achieved that common high-strength mortar or self-leveling concrete mortar depositing construction, without cohering
The high prices proprietary material grouting construction such as mortar, saves material cost, reduces difficulty of construction.The vertical muscle and stirrup of parent segment
The ratio of reinforcement can be identical as public segment, the intensity of parent segment no longer needs to be checked, and bond length, which meets minimum bond length, to be wanted
It asks, seam crossing adhesion strength does not play control action, is consistent the design method of segment assembled pier stud with cast-in-place pier stud, drops
Low design difficulty.Assembling process uses consistent operational procedure, reduces difficulty of construction.If uniline dosage is big, lead to
Design standard segment is crossed, industrialized production is realized, the prefabricated processing cost of segment can be further decreased.
Preferably, several second vertical muscle are additionally provided on the parent segment, the second vertical muscle is along second ontology
Elongated arrangement, the quantity of the second vertical muscle are equal to the quantity of the described first vertical muscle, and the sectional area of the second vertical muscle is equal to institute
