Technical Field
The utility model relates to the technical field of anchoring of main bearing members of concrete bridges, in particular to a high-strength aluminum alloy anchoring structure.
Background
The shear key is used as an important component in the corrugated steel web girder bridge, is one of the most critical stress components for ensuring the joint work of two different materials of steel and concrete in the girder bridge structure, and has the main functions of resisting the horizontal shear force at the interface of the steel and the concrete and preventing the mutual sliding between the steel and the concrete; and secondly, the lifting between the concrete member and the steel member is resisted. The anchor bolt is suitable for anchoring main bearing members of the concrete bridge and is not suitable for the severely weathered concrete bridge. In the existing common technology, a vertical perforated plate is added at the upper end of a corrugated steel web, then anchors transversely penetrate through the perforated plate, a plurality of anchors bear the shearing force of steel members, and as the perforated plate is positioned in the middle of the anchors, the shearing force born by the anchors is concentrated, the anchors are easy to deform under stress, and even the anchoring structure fails.
The Chinese patent CN209323342U discloses a novel corrugated steel web girder bridge Twin_PBL shear key, the proposal is added with two perforated steel plates to improve the integral rigidity and the torsion resistance of the shear key on the basis of shearing resistance of the original PBL shear key, and simultaneously utilizes isotropy of stud shearing resistance to enhance the transverse shearing resistance of the shear key. According to the scheme, the contact point or the contact area is increased, so that the effect of dispersing shear force is achieved, the torsion resistance and the transverse shear resistance of the PBL shear key are expected to be enhanced, and finally the overall rigidity is increased. However, in use, the basalt fiber steel is easy to be anchored and damaged under the action of external force, the repairing difficulty is high, the transverse constraint of the perforated steel plate is insufficient, and the single fiber steel still needs to bear high shearing force. Considering the working environment of the anchor bolts, the conventional fiber steel cannot meet the actual requirements.
The high-strength aluminum alloy anchoring structure can provide transverse constraint, improve the stress condition of an anchor, greatly improve the overall performance of the structure, and improve the strength and corrosion resistance of the anchor bolt structure by adopting high-strength aluminum alloy materials.

Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
The utility model is provided by figures 1 to 3, which comprises an open-pore steel plate 1, wherein a plurality of anchoring parts are uniformly distributed on the open-pore steel plate 1, a plurality of through holes corresponding to the anchoring parts one by one are uniformly distributed on the open-pore steel plate 1, each anchoring part comprises a U-shaped bolt 2 with an upward opening, the U-shaped bolt 2 penetrates through the open-pore steel plate 1 through the through hole, a horizontal transverse strut 3 is fixed in a cavity of the U-shaped bolt 2, and the open-pore steel plate 1 is provided with a relief hole corresponding to the transverse strut 3.
In order to improve the deformation resistance of the anchoring piece, a plurality of transverse struts 3 are arranged in each U-shaped bolt 2, and the transverse struts 3 are distributed up and down.
In order to provide reliable constraint for the transverse direction of the perforated steel plate 1, the outer surfaces of the transverse struts 3 are in a threaded structure, a plurality of nuts 4 are rotated on each transverse strut 3, and the nuts 4 are distributed on two sides of the perforated steel plate 1.
In order to improve the corrosion resistance of the anchoring structure, the U-shaped bolt 2, the transverse strut 3 and the nut 4 are all made of high-strength aluminum alloy materials.
It should be noted that the anchoring structure can be suitable for the positioning requirement of a single perforated steel plate 1, and also can be suitable for the structure of a plurality of perforated steel plates 1 in the background art, and similarly, for convenience of illustration and understanding, only the perforated steel plates 1 are shown in the drawings, but it should be noted that two or more parallel perforated steel plates 1 can be fixed on the same anchor, and nuts 4 are arranged on two sides of each steel plate to realize transverse constraint.
Before the anchor assembly is carried out on the perforated steel plate 1, the U-shaped bolt 2 and the transverse strut 3 are separated, when the perforated steel plate 1 is assembled, the U-shaped bolt 2 passes through the through hole, then the transverse strut passes through the abdication hole, then the end part of the transverse strut 3 is welded and fixed with the U-shaped bolt 2, the nut 4 is screwed, the perforated steel plate 1 is fixed by the nut 4, at the moment, one anchor assembly is finished, and finally a plurality of anchors are sequentially installed on the perforated steel plate 1, so that the perforated steel plate can be normally used.
