Abstract
The utility model discloses a continuous rigid frame bridge steel tie beam of assembled. The bridge pier comprises anchor bolts (2) which are embedded in the inner sides of two bridge piers (1) and symmetrically arranged, and the anchor bolts are connected with a bearing steel plate (4) through a connecting plate (3). Adopt the technical scheme of the utility model, tie beam and pier junction can not ftracture, have improved the durability of bridge. Additionally, the technical scheme of the utility model also can regard as the interim support in the pier construction, wait that the bridge construction finishes the back and demolish.
Description
Technical field
the utility model relates to a kind of assembling continuous rigid frame bridge steel binder, belongs to bridge construction and technical field of construction.
Background technology
prestressed concrete continuous rigid-framed bridge is one of current more common a kind of bridge pattern, the bridge pier of this kind of bridge generally adopts two board-like solid pier of limb or twin legged thin wall hollow pier, for the bridge pier that these are higher, generally steel concrete binder is set between two limbs.
existing binder cross section is generally board-like or case structure.In the process of actual motion, very easily produce crack at steel concrete binder and bridge pier junction, the appearance in crack can reduce the durability of bridge construction.
in addition, in the practice of construction of continuous rigid frame bridge bridge pier, for the bridge pier that some are not very high, binder is not set in design, but for increasing the interim rigidity of bridge pier and support, provisional lateral ties structure need be set between two limb bridge pier, after bridge builds up, then by these interim lateral ties structural demolitions.
Utility model content
the purpose of this utility model is, provides a kind of assembling continuous rigid frame bridge steel binder, to solve the technical problem that existing structure easily produces crack, solves the technical problem arranging interim lateral ties between two limb bridge pier simultaneously.
the technical solution of the utility model:
a kind of assembling continuous rigid frame bridge steel binder, comprise and be embedded in symmetrically arranged crab-bolt inside two bridge piers, crab-bolt is connected with carrying steel plate through junction plate.
in aforementioned steel binder, described crab-bolt is L shape, and one end, long limit of L shape is provided with screw thread, and the minor face of L shape and one section of long limit are embedded in bridge pier, and long limit establishes threaded end to expose bridge pier side to be connected with junction plate through nut.
in aforementioned steel binder, be provided with the crab-bolt of the equidistant horizontal distribution of two rows inside described bridge pier, two row's crab-bolts are symmetrical arranged.
in aforementioned steel binder, described junction plate is steel angle structure, and the two sides of angle steel are equipped with the through hole corresponding with crab-bolt spacing, and the through hole of junction plate side is enclosed within crab-bolt and establishes threaded one end, fixes through nut and bridge pier; Junction plate in two row's crab-bolts is symmetrical fixing back-to-back.
in aforementioned steel binder, described carrying steel plate is rectangle, and the both sides that rectangle is relative are clipped between junction plate fixing on two bridge piers, are fixedly connected with through bolt.
compared with prior art, the utility model provides a kind of standardized continuous rigid frame bridge bridge pier binder structure, and adopt the technical solution of the utility model, can not ftracture in binder and bridge pier junction, improve the durability of bridge.In addition, the technical solution of the utility model also can be used as the temporary support in Bridge Pier Construction, removes after treating bridge construction.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
being labeled as in accompanying drawing: 1-bridge pier, 2-crab-bolt, 3-junction plate, 4-carry steel plate, 5-nut, 6-bolt.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of assembling continuous rigid frame bridge steel binder, as shown in Figure 1, comprise and be embedded in symmetrically arranged crab-bolt 2 inside two bridge piers 1, crab-bolt 2 is connected with carrying steel plate 4 through junction plate 3.Crab-bolt 2 is L shape, and one end, long limit of L shape is provided with screw thread, and the minor face of L shape and one section of long limit are embedded in bridge pier 1, and long limit establishes threaded end to expose bridge pier 1 side to be connected with junction plate 3 through nut 5.Crab-bolt 2, the two row crab-bolt 2 being provided with the equidistant horizontal distribution of two rows inside bridge pier 1 is symmetrical arranged.Junction plate 3 is steel angle structure, and the two sides of angle steel are equipped with the through hole corresponding with crab-bolt 2 spacing, and the through hole of junction plate 3 side is enclosed within crab-bolt 2 and establishes threaded one end, fixes through nut 5 and bridge pier; Junction plate 3 in two row's crab-bolts 2 is symmetrical fixing back-to-back.Carrying steel plate 4 is rectangle, and the both sides that rectangle is relative are clipped between junction plate 3 fixing on two bridge piers 1, are fixedly connected with through bolt 6.
Embodiment
during concrete enforcement, first the tension and compressive resistance that need between continuous rigid frame bridge bridge pier two limb is calculated, the thickness and the width that carry steel plate 4 and junction plate 3 is determined according to result of calculation, and the quantity of cast-in fixing bolt 2 and arrangement, and determine quantity and the arrangement of bolt 5.Then assembled by shown in Fig. 1.
fig. 2 is the application site schematic diagram of the utility model on continuous rigid frame bridge, and in figure, circle labeling position is application site of the present utility model.
be more than embody rule example of the present utility model, do not form any restriction of the present utility model, if one piece carries the bearing capacity that steel plate 4 does not reach designing requirement, multiple carrying steel plate 4 can be set by said structure.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all belong to protection domain of the present utility model.
