Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, relates to the construction of high bridge piers, and specifically relates to a high bridge pier reinforcement binding frame based on a rigid frame. Background Art

[0002] like Figure 1 As shown, high bridge piers are usually constructed in sections. When installing the steel bars of each section, a rigid skeleton needs to be set in the pier body steel cage to ensure the stability of the pier body steel bars. The rigid skeleton includes four vertical bars 12 set at the four corners of the pier body steel cage, and a layer of horizontal bars 13 are welded between the four vertical bars at a certain interval. The usual method of installing high pier steel bars is to first install the rigid skeleton, then install the pier body main bars 10 one by one, and finally tie stirrups 11 on the main bars. This construction method is inefficient, the construction workers have to work at high altitude for a long time, and the labor intensity is high. Summary of the invention

[0003] The utility model aims to solve the above problems and provides a high pier steel bar binding frame for bridges based on a rigid skeleton, which binds the steel bars of a pier body segment into a whole on the ground and then hoists and installs the whole frame to improve construction efficiency.

[0004] The technical solution of the utility model is as follows:

[0005] A reinforcement binding frame for high piers of bridges based on a rigid skeleton, characterized in that it comprises two parallel longitudinal beams, at least three transverse beams are welded equidistantly between the tops of the two longitudinal beams, a long strip of vertical plates are welded at both ends of each transverse beam, a long strip of toothed plate is vertically movably installed on the upper edge of each vertical plate, the outer side of the toothed plate is connected to the vertical plate by bolts, a plurality of main reinforcement slots are equidistantly provided on the inner side of the toothed plate, and a plurality of main reinforcement positioning grooves are equidistantly provided on the top surface of each transverse beam along the horizontal direction.

[0006] The utility model can form the pier body reinforcement cage by assembling it horizontally on the ground in sections, and use the rigid frame as a reinforcement cage lifting bracket to lift the reinforcement cage vertically to the installation position, thus giving full play to the advantage of the strong rigidity of the rigid frame rod material, and can greatly improve the pier body reinforcement installation construction efficiency.

[0013] like Figure 2 , Figure 3 As shown, the utility model comprises two parallel longitudinal beams 1, at least three transverse beams 2 are equidistantly welded between the tops of the two longitudinal beams, a long vertical plate 3 is welded at both ends of each transverse beam, the plate surface of the vertical plate is parallel to the longitudinal axis of the transverse beam, a long tooth plate 4 is vertically movably installed on the upper edge of each vertical plate, the inner side of the tooth plate 4 is connected to the vertical plate by bolts 5, a plurality of main reinforcement bayonet holes 6 are equidistantly provided on the inner side of the tooth plate, and a plurality of main reinforcement positioning grooves 7 are equidistantly provided on the top surface of each transverse beam 2 along the transverse direction of the transverse beam.

[0014] When the utility model is implemented, two strip-shaped slide grooves 8 can be arranged on each vertical plate 3 in the horizontal direction, and the connecting bolts 5 between the vertical plate and the tooth plate are inserted in the slide grooves 8 and can slide along the slide grooves. When the bolts 8 are loosened, the tooth plate 4 can slide along the slide grooves 8 together with the bolts 8, thereby adjusting the position of the tooth plate 4; when the bolts are tightened, the position of the tooth plate can be fixed.

[0015] To facilitate the movement of the toothed plates, a push-pull handle 9 can be welded on each toothed plate 4 .

[0016] When the utility model is implemented, the spacing between the main reinforcement slots 6 on the tooth plate 4 and the spacing between the main reinforcement positioning grooves 7 on the crossbeam 2 are set according to the spacing between the main reinforcements of the pier body.

[0017] like Figure 4 , Figure 5 As shown, the method for tying the pier body reinforcement of the utility model is as follows:

[0018] Place the main reinforcement 10 of the pier horizontally in the main reinforcement slots 6 on the tooth plates 4 on both sides of the tire frame, and in the main reinforcement positioning grooves 7 on each crossbeam 2, place the rigid frame horizontally between the tooth plates on both sides, and place the main reinforcement at the designed spacing of the main reinforcement on the top cross bar 13 of the rigid frame, weld all the main reinforcements to the rigid frame, and then install the stirrups 11 and weld them to the main reinforcement 10, and the steel bars of a pier segment are welded into an integral steel cage. Loosen the fixing bolts of the tooth plate, slide the tooth plate backward, and make the main reinforcements on both sides disengage from the tooth plate slots.

[0019] like Figure 6 As shown in the figure, hanging points are set at the four corners of the rigid frame. The crane is connected to the hanging points through steel wire ropes, and the steel cage is lifted to a vertical state. It is then lifted above the pier and slowly lowered to connect with the main reinforcement of the pier and the rigid frame that have been constructed below, thus completing the steel bar installation of a segment.
