Problems solved by technology

The disadvantage of it is that the material recycling rate is low and the waste is large.
In addition, welding brackets and pre-embedded steel plates are mainly welded and fixed by vertical welding and overhead welding. Since the bridge piers using the bracket construction method are generally high, workers have little room for fixing and welding steel trusses, and the welding quality is not easy to guarantee.

Embodiment

[0015] Consists of symmetrically arranged shaped truss platforms 3 such as figure 1 As shown, the upper end side of the forming truss platform 3 is connected to the upper hinge seat X through the connecting steel pin 5, and the lower end side of the forming truss platform 3 is connected to the lower hinge seat Y through the connecting steel pin 5. The upper hinge seat X and The lower hinge seat Y is connected to the symmetrically arranged upper hinge seat X and the lower hinge seat Y via the connecting shaft and the JM anchor 2.

[0016] The bottom surfaces of the upper hinge seat X and the lower hinge seat Y are provided with pressure-resistant rubber pads 4, as shown in Figures 3 and 5. Place

[0017] The connecting shaft described above is high-strength finish-rolled rebar 1.

[0018] There are at least two connecting shafts.

[0019] The embodiment of this device is composed of high-strength finish-rolled rebar 1, JM anchorage 2, forming truss platform 3, upper hinge se...

Abstract

The invention relates to a bearing bracket, comprising symmetrical molded truss platforms. One side of the upper end of each molded truss platform is connected with an upper hinge pedestal through a steel coupling pin and one side of the lower end of each molding girder platform is connected with a lower hinge pedestal through a steel coupling pin. The upper hinge pedestal and the lower hinge pedestal are connected with an upper hinge pedestal and a lower hinge pedestal which are symmetrically arranged through a connecting shaft and a JM anchor. Therefore, the invention solves the technical problem in the suspended casting construction of the bearing bracket at the top of a continuous pier in bridge construction. The bearing bracket is simple in stress and is safe and reliable, convenient to install and disassemble and can be used repeatedly; so the bearing bracket is widely applied in the construction of various concrete piers.

Description

Technical field [0001] The invention relates to a load-bearing bracket, in particular to a load-bearing bracket on the top of a continuous beam pier with a suspension casting method. Background technique [0002] Suspension cast continuous beam is a common design method in the design of long-span bridges. The 0# block at the top of continuous girder pier with cantilever casting method is generally constructed by welded bracket cast-in-place method, and the bracket is mostly erected in the following way: the pre-embedded steel plate is buried close to the side wall formwork of the pier body, and the steel truss is placed in the designated processing site according to Welding is required, and after the formwork is removed from the pier body, the formed steel trusses are welded to the pre-embedded steel plates to form brackets. Utilize the bracket to set up the mold, install the steel bars, and pour the 0# block concrete on the top of the pier, and the bracket can also be used...
