Description

Technical Field

[0001] The utility model relates to the technical field of bridge reinforcement, in particular to a bridge pier reinforcement structure. Background Art

[0002] Bridge piers are important components that support bridge structures and are usually made of concrete or steel. They bear the weight of the bridge superstructure (such as the bridge deck, beams, etc.) and transfer the gravity to the foundation or piers, and finally disperse it to the ground or pier foundations; during the construction process, piers are usually cast or assembled according to the design drawings to ensure that they have sufficient strength and stability to support the entire bridge structure.

[0003] Since bridge piers bear huge loads from the road surface, bridges and vehicles, they will age or crack after a certain number of years of use. The existing construction method is usually to directly demolish and rebuild or to use molds to surround and pour reinforced concrete for reinforcement. However, direct demolition and reconstruction will cause huge consumption of resources, time and costs for piers that can still be used, while pouring reinforced concrete for reinforcement requires more manual participation and more precise construction technology and equipment, resulting in high overall construction costs and long construction time. Utility Model Content

[0004] The utility model aims to provide a bridge pier reinforcement structure, which can facilitate the reinforcement of the bridge pier, accelerate the overall construction progress, and save construction costs.

[0005] The embodiment of the utility model is realized by the following technical scheme: A bridge pier reinforcement structure, comprising:

Example

[0027] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4As shown, the utility model is a bridge pier reinforcement structure, including hoop plates 1, which are multiple and arc-shaped, hingedly installed between two to form a long strip, and the hinge shafts between adjacent hoop plates 1 are pin-shaped to achieve detachable connection, so as to adjust the number of hoop plates 1, and ear plates 14 are welded at both ends of the multiple hoop plates 1, and the hoop plates 1 at both ends are fixed by bolts 8 passing through the ear plates 14; the bending frame 2 is hingedly installed at the upper and lower ends of each hoop plate 1. The hinge axis is tangent to the outer circumference of the pier; the plywood 3 is in the shape of an arc sheet, and is fixedly welded to one end of each bending frame 2 away from its own hinge point, and is used to press against the pier, and after the multiple plywood 3 is rotated and fitted on the pier, the whole forms a circular ring, so as to better reinforce the pier;

[0028] Reference Figure 2 , Figure 3 A grouting groove 11 is provided on one side of each hoop piece 1 and the splint 3 near the pier column, and a steel mesh 5 is fixedly welded in the grouting groove 11. The steel mesh 5 is laid in the grouting groove 11 and is located in the middle position of the grouting groove 11. A grouting hole 31 connected with the grouting groove 11 is provided near the upper end of each hoop piece 1 and the splint 3, so as to inject cement mortar into the grouting groove 11, and a plurality of thorn rods 12 are fixedly welded on the bottom wall of the grouting groove 11. The thorn rod 12 is made of stainless steel metal material, and the thorn rod 12 extends out of the grouting groove 11 toward one side of the pier column. At the same time, the thorn rod 12 is provided with a plurality of bending notches 121 along its length direction. After the hoop piece 1 and the splint 3 are tightly fixed on the pier column, a part of the thorn rod 12 will pierce the pier column, or bend along the bending notch 121. After the cement mortar is injected into the grouting groove 11, the cement mortar can be better combined and fixed with the pier column.

[0029] A connecting opening 32 is provided between adjacent hoop pieces 1 to connect the grouting grooves 11 between adjacent hoop pieces 1. There are multiple connecting openings 32, and the multiple connecting openings 32 are all opened toward the side of the pier. At the same time, a connecting opening 32 is also provided between adjacent plywood 3 to connect the grouting grooves 11 between adjacent plywood 3. The connecting opening 32 of the plywood 3 is also opened toward the side of the pier. The connecting opening 32 allows cement mortar to flow in, thereby improving the strength of the entire plywood 3 and hoop piece 1. Rubber pads 13 are provided in the gaps between adjacent hoop pieces 1 and the gaps between adjacent plywood 3. The rubber pads 13 can prevent cement mortar from flowing out, thereby reducing the overall strength.

[0030] Reference Figure 2 , Figure 3In order to improve the connection strength between the upper and lower clamping plates 3 and the hoop pieces 1, U-shaped clamping rods 6 are vertically penetrated on the upper adjacent clamping plates 3, and the U-shaped clamping rods 6 pass through the lower adjacent hoop pieces 1 and the adjacent clamping plates 3 at the same time. At the same time, the U-shaped clamping rods 6 pass through the connecting openings 32 between the adjacent hoop pieces 1 and the adjacent clamping plates 3. When the cement mortar is poured in, the cement mortar will be poured together with the U-shaped clamping rods 6, thereby improving the overall strength and being able to improve the connection strength between the adjacent hoop pieces 1 and the adjacent clamping plates 3.

[0031] Reference Figure 1 , Figure 2 The fixing part 4 includes a hoop 41, which is divided into two halves, which are hingedly installed with each other and are made of high-strength stainless steel.

Positioning slots 71 for inserting the positioning rod 7 are correspondingly opened on the upper and lower end surfaces of the hoop 1. When the positioning rod 7 is inserted into the positioning slot 71, the clamp 3 is in a position close to the side wall of the pier, and the positioning rod 7 is threaded with a positioning stud 72 connected to the bottom wall of the positioning slot 71. When the clamp 3 is abutted and fixed on the pier, the positioning rod 7 is tightened by the positioning stud 72, so as to further fix the position of the clamp 3, thereby preventing the clamp 3 from rotating and opening and failing when subjected to excessive external force.

[0033] The working process of this embodiment is: first, adjust the number of appropriate hoop plates 1 according to the diameter of the pier, and then tighten the multiple hoop plates 1 to the parts of the bridge pier that need to be processed, use bolts 8 to pass through the ear plates 14 to tighten and fix all hoop plates 1, and then rotate the clamps 3 to make all the clamps 3 press against the pier, and then use the clamps 41 to fix the positions of all the clamps 3 on the upper and lower sides of the hoop plates 1 respectively, and insert the U-shaped clamp rod 6 vertically corresponding to the adjacent clamps 3 along the top, tighten the positioning studs 72 to fix the positioning rods 7 to further fix the clamps 3, and finally pour cement mortar through the grouting holes 31 of each hoop plate 1 and clamp 3. After the cement mortar solidifies, the pier is reinforced. The overall operation is simple, the fixing effect is good, the construction efficiency is high, and the construction cost is saved.
