Abstract
The utility model discloses a connection structure of a bridge support padstone and an abutment. The connection structure of the bridge support padstone and the abutment comprises the abutment and the support padstone on the abutment, wherein the support padstone is embedded in the abutment, and a U-shaped vertical steel bar in the support padstone extends into the abutment and is fixedly welded to a main reinforcing bar in the abutment. The connection structure of the bridge support padstone and the abutment adopts a raggle embedded type pouring method, compared with a traditional method that a steel bar is embedded before pouring, the shearing resistance and compressive strength are good, the construction is convenient, the concrete between the support padstone and a bent cap of the abutment is well combined, and overall stress is benefited.
Description
Technical field
The utility model relates to the bridge construction field, is specifically related to bridge pad pinner and pier syndeton.
Background technology
According to the bridge design standard, for satisfying partial pressing and changing the bearing needs, the bearing below must arrange bearing pad stone.The dead load of bridge superstructure and dynamic load are delivered to infrastructure and basis by bearing pad stone, are the most concentrated stressed positions.Traditional bearing pad stone job practices is pre-buried pinner reinforcing bar when building the pier bent cap, treats that the pier bent cap builds to relocate after the moulding to build pinner, plays the shearing resistance effect.Thereby need in bent cap, to reserve vertical shear reinforcement, and need during the bent cap construction template is punched or the reserved steel bar head later stage carries out reinforced mesh and makes, cause pinner to be combined bad with the bent cap end face, it is numerous and diverse to construct, the pinner shear strength is little, very easily damages, thereby causes serious hidden danger of quality.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of bridge pad pinner and pier syndeton, and bearing pad stone embeds in the pier, and shearing resistance and compressive strength are good, concrete is combined between easy construction, bearing pad stone and pier bent cap, and it is stressed to be conducive to integral body.
The utility model is achieved through the following technical solutions:
Bridge pad pinner and pier syndeton comprise the bearing pad stone of pier and top thereof, and described bearing pad stone embeds in the pier, and the vertical reinforcement in the bearing pad stone stretches in the pier, with the fixing welding of the main muscle in the pier.
The further improvement of the utility model scheme is that the vertical reinforcement in the described bearing pad stone is " U " type.
Further improvement project of the present utility model is, the interlaced distribution that makes progress of described " U " type vertical reinforcement opening.
The job practices that the bridge pad pinner is connected with pier, described job practices are the embedded casting method of raggle, specifically may further comprise the steps:
(1) Dun Ding cutter hair: after the bent cap body of pier is built and is finished, treat that intensity reaches 70% after, determine the pinner position, cut prefabricated pinner scope place bent cap concrete to exposing main muscle in the bent cap, form rectangular recess;
(2) steel bar framework of bearing pad stone is made: vertical reinforcement is positioned in the groove, and its base point solid welding is fixed on the main muscle of bent cap, the short muscle of colligation structure, the steel bar framework integral body of formation bearing pad stone; (3) formwork erection is built bearing pad stone: shuttering around the steel bar framework of bearing pad stone, in template, build stone concrete then, and namely finish the syndeton of bearing pad stone and pier after the moulding.
Vertical reinforcement described in the step (2) is " U " type, opening interlaced being positioned in the groove that make progress.
The utility model compared with prior art has following obvious advantage:
One, the utility model is because bearing pad stone embeds in the pier bent cap, and circumferential concrete can play the cuff effect, and shearing resistance and compressive strength improve greatly.
Two, need not pre-buried pinner reinforcing bar before the construction of the utility model bearing pad stone, reduced difficulty of construction, convenient construction.
Three, the utility model since to pier bent cap jacking row cutter hair, build bearing pad stone concrete with between the pier bent cap and be combined better, it is stressed to be conducive to integral body.

Fig. 1 is the utility model elevation.
Fig. 2 is the utility model plan view.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises the bearing pad stone 2 of pier 1 and top thereof, and described bearing pad stone 2 embeds in the pier 1, and " U " type vertical reinforcement 3 in the bearing pad stone 2 stretches in the pier 1, with the main muscle 4 fixing welding in the pier 1, the interlaced distribution that makes progress of vertical reinforcement 3 openings.
The job practices that the bridge pad pinner is connected with pier is the embedded casting method of raggle, specifically may further comprise the steps:
(1) pier top cutter hair: after the bent cap body of pier is built and is finished, treat that intensity reaches 70% after, determine the pinner position, cut prefabricated pinner scope place bent cap concrete to exposing main muscle in the bent cap, form rectangular recess;
(2) steel bar framework of bearing pad stone is made: will " U " type vertical reinforcement by structure apart from opening interlaced being positioned in the groove that make progress, and its base point solid welding is fixed on the main muscle of bent cap the short muscle of colligation structure, the steel bar framework integral body of formation bearing pad stone; (3) formwork erection is built bearing pad stone: shuttering around the steel bar framework of bearing pad stone, in template, build stone concrete then, and namely finish the syndeton of bearing pad stone and pier after the moulding.
Claims (3)
1. bridge pad pinner and pier syndeton, the bearing pad stone (2) that comprises pier (1) and top thereof, it is characterized in that: described bearing pad stone (2) embeds in the pier (1), vertical reinforcement (3) in the bearing pad stone (2) stretches in the pier (1), with the fixing welding of the main muscle (4) in the pier (1).
2. bridge pad pinner according to claim 1 and pier syndeton is characterized in that: the vertical reinforcement (3) in the described bearing pad stone is " U " type.
3. bridge pad pinner according to claim 2 and pier syndeton is characterized in that: the interlaced distribution that makes progress of described " U " type vertical reinforcement (3) opening.
