Abstract

The utility model relates to a high mound bracket supports bracket anchor structure, pre-buried anchor bolt in the high mound pier body, be equipped with 3 horizontal tenons on the bracket anchor board, bracket mounted position is equipped with the recess that the tenon on 3 and the anchor board corresponds on the mound body, 3 tenons on the anchor board gomphosis respectively to 3 recesses on the mound body in, the anchor board passes through anchor bolt and pier body anchor. The utility model has the advantages that 3 tenon structures on the bracket anchoring plate are occluded with the reserved opening of the pier body, so that the vertical load acting on the anchoring plate is borne by the concrete of the pier body, and the stress capacity is stronger; the bracket mounting and dismounting process has no welding and cutting operation, the structure of the bracket is not damaged, and the bracket can be used in a circulating way.

Description

High mound bracket supports bracket anchor structure

Technical Field

The utility model belongs to the technical field of the bridge construction, a bearing structure of bridge superstructure construction bracket is related to, concretely relates to anchor structure of high mound bracket support bracket.

Background

In the process of bridge construction, overhanging concrete pouring construction is usually carried out, such as a No. 0 block, a cable tower cross beam, a high pier capping beam and the like of a rigid frame bridge. When the pier is higher, the ground support cannot be erected, and the bracket method is mainly adopted for the concrete construction of the overhanging part. The bracket needs to be supported by means of a bracket anchored to the pier body. The anchor of the bracket and the pier body is usually in two modes, one mode is to embed a bolt in the pier body, the bracket is anchored with the pier body through the embedded bolt, the vertical shearing force is resisted through the friction force between the pier body and the bracket and the high-strength bolt, but the bracket and the pier body are not tightly attached due to the uneven concrete surface of the pier body, the friction force generated in the compression process is small, the shearing resistance of the bolt is weak, and the safety and reliability of the support are low; the other mode is that the steel plates are embedded in pier body concrete, and the brackets are welded with the embedded steel plates, but a large amount of field overhead welding operation is needed, the construction safety risk is large, the welding quality is difficult to control, and the brackets need to be cut when being detached, so that the nondestructive turnover cannot be realized, the material waste can be caused, and the construction cost is high.

Disclosure of Invention

The utility model aims at improving the structure of traditional bracket and pier shaft anchor mode, improving bracket and pier shaft anchor strength and security to cancel on-the-spot welding process, convenient construction, reduce cost.

The technical scheme of the utility model as follows:

the utility model provides a high mound bracket supports bracket anchor structure, pre-buried anchor bolt in the high mound pier body, the bracket includes the anchor board, and anchor board one side welding has bracket roof and side riser, and the anchor board passes through anchor bolt anchor on the mound body, its characterized in that: the other side of the anchoring plate is provided with 3 transverse tenons, and the tenons are provided with screw holes corresponding to the anchoring bolts; the bracket mounted position is equipped with the recess that 3 tenons on with the anchor board correspond on the pier shaft, and pre-buried anchor bolt front end is outstanding to the pier shaft outside in the recess in the pier shaft, 3 tenons on the anchor board gomphosis respectively to 3 recesses on the pier shaft, and the screw and spiro union nut on the tenon are passed to anchor bolt front end and are anchored with the anchor board.

The utility model has the advantages that 3 tenon structures on the bracket anchoring plate are meshed with the reserved notches of the pier body, so that the vertical load acting on the anchoring plate is born by the pier body concrete, the characteristic of high compressive strength of the concrete is fully exerted, the contact area between the anchoring plate and the concrete is increased, the mutual friction force between the anchoring plate and the concrete is enhanced, and the stress capacity is stronger; the bracket is welded in advance, and is installed through the embedded bolt on site, so that the construction speed is high, welding and cutting operations are not required in the installation and disassembly processes, the structure of the bracket is not damaged, the bracket can be used in a turnover manner, and the economic benefit is obvious.

Detailed Description

As shown in fig. 1, the utility model discloses pre-buried anchor bolt 2 that has in high mound pier shaft 1, the bracket includes

anchor board

3, and 3 one side welding of anchor board have bracket roof 4 and side riser 5, and anchor board 3 is through anchor bolt 2 anchor on pier shaft.

The corbel is structured as shown in fig. 2 and 3, 3 transverse tenons 31 are arranged on the other surface of the anchoring plate 3, and screw holes 32 corresponding to anchoring bolts are arranged on the tenons 31.

As shown in fig. 4 and 5, 3 grooves 6 corresponding to the tenons on the anchoring plates are arranged at the bracket mounting positions on the pier body 1, and the front ends of the anchoring bolts 2 pre-embedded in the pier body protrude out of the pier body from the grooves.

As shown in figure 1, 3 tenons 31 on the bracket anchor plate 3 are respectively embedded into 3 grooves on the pier body, and the front end of the anchor bolt 2 passes through a screw hole on the tenon and is screwed with a nut 7 to be anchored with the anchor plate 3.

When the utility model is implemented, the bracket is welded on the ground in advance, the thickness of the tenon on the anchoring plate is not less than 3cm, and the distance is 15 cm; when pouring pier body concrete, reserving a groove at the designed installation position of the bracket, and embedding an anchor bolt; when the bracket is installed, the anchoring plate is directly embedded into the groove on the pier body and is anchored with the pier body through the anchoring bolt. The installation rate is fast, convenient to detach, and after the construction, the bracket of dismantling can have enough to meet the need the use.

Claims

1. The utility model provides a high mound bracket supports bracket anchor structure, pre-buried anchor bolt in the high mound pier body, the bracket includes the anchor board, and anchor board one side welding has bracket roof and side riser, and the anchor board passes through anchor bolt anchor on the mound body, its characterized in that: the other side of the anchoring plate is provided with 3 transverse tenons, and the tenons are provided with screw holes corresponding to the anchoring bolts; the bracket mounted position is equipped with the recess that 3 tenons on with the anchor board correspond on the pier shaft, and pre-buried anchor bolt front end is outstanding to the pier shaft outside in the recess in the pier shaft, 3 tenons on the anchor board gomphosis respectively to 3 recesses on the pier shaft, and the screw and spiro union nut on the tenon are passed to anchor bolt front end and are anchored with the anchor board.
