Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically, to an auxiliary reinforcement structure of a bridge support. Background Art

[0002] In construction projects, bridge columns made of reinforced concrete are usually used to support bridges. This support method is low-cost and can achieve good support effects.

[0003] Construction projects must not only meet usage requirements, but also safety performance requirements. During the construction of bridges, although the pillars made of reinforced concrete can basically meet the requirements of the construction party, for the sake of higher bridge safety, it is still necessary to set up reinforcement structures to assist in reinforcing the bridge pillars. In the process of reinforcing bridge columns using traditional external steel reinforcement methods, there is a lack of structural design, so that the steel used for reinforcement is only reinforced by the strength of the material itself and lacks structural auxiliary reinforcement.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0010] The utility model is further configured as follows: a gap 2 is provided between the lower end surface of the support frame and the lower end surface of the support plate.

[0011] The utility model is further configured as follows: the support plate, the support block and the support frame are all made of D406A type high-strength steel.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Example: Auxiliary reinforcement structure of bridge pillars, such as Figure 1-Figure 3As shown, it includes a plurality of connecting sleeves 2 which are detachably connected to the periphery of each bridge column 1 of the bridge through a bolt member 1, a support plate 3 is fixedly installed through the connecting sleeve 2 by a bolt member 2, a plurality of support blocks 31 are arranged in an array on the support plate 3, the support blocks 31 are vertically arranged with the support plates 3 and the support blocks 31 are fixedly connected to the support plates 3 by welding, a gap of equal height is provided between the support blocks 31 on the opposite end faces of two support plates 3 on the same bridge column 1, a support frame 4 is provided between the support plates 3 on the same side, a support rod 41 which matches the gap is fixedly connected in the support frame 4, and the support frame 4 is fitted with the support block 31 through the support rod 41 to support The pressure of the bridge on the support frame 4 is dispersed to each support block 31. At the same time, the support plate 3, the support block 31 and the support frame 4 are all made of D406A type high-strength steel. The selection of materials enhances the supporting and reinforcing effect of the bridge of the utility model. The utility model disperses the pressure of the bridge to the external support plate 3, reduces the pressure on the bridge column 1, and makes the weight of the bridge not only need to overcome the material strength of the bridge column 1, but also need to overcome the material strength of the support plate 3 at the lower end of the bridge and the connection strength of the support block 31 welded to the support plate 3, which greatly enhances the supporting effect on the bridge and ensures the safety and stability of the bridge.

[0019] like Figure 1-Figure 3 As shown, the support plate 3 is arranged perpendicular to the horizontal plane through the connecting sleeve 2, and the bottom end of the support plate 3 and the bottom end of the bridge column 1 are located in the same horizontal plane. At the same time, a support plate 42 is fixedly installed on the upper end surface of the support frame 4, and the upper end surface of the support plate 42 contacts the lower surface of the bridge, and the support plate 42 and the upper surface of the bridge column 1 are located in the same horizontal plane. The design of these structures aims to ensure that the force exerted on the bridge column 1 can be dispersed to the support plate 3, so that the support plate 3 can maximize its own material and structural advantages and better reinforce the bridge. A spacing of two is provided between the lower end surface of the support frame 4 and the lower end surface of the support plate 3. The spacing of two makes the support frame 4 separated from the ground. This arrangement allows the pressure of the bridge exerted on the support frame 4 to be fully transferred to the support plate 3 through the support rod 41 and the support block 31, so that the strength of the support plate 3 can better play a supporting and reinforcing role.

[0020] like Figure 1-Figure 3 As shown, each bridge column 1 is provided with at least two connecting sleeves 2, and the connecting sleeves 2 include a secondary sleeve 21 and a main sleeve 22 which are connected to each other. The secondary sleeve 21 and the main sleeve 22 are tightly connected to the periphery of the bridge column 1 by a bolt. The design purpose of this structure is to facilitate the installation of the connecting sleeve 2 and to allow the connecting sleeve 2 to be stabilized at a certain fixed height on the bridge column 1. The secondary sleeve 21 and the main sleeve 22 are fixedly connected with a mounting plate 23 for connecting the support plate 3. The mounting plates 23 on the same bridge column 1 are all arranged in the same vertical horizontal plane to ensure that the support plate 3 is placed vertically, thereby improving the supporting effect on the bridge.

[0021] Working principle: When building a bridge, use bolts to sleeve the secondary sleeve 21 and the main sleeve 22 on the outer surface of the bridge column 1, and use the same method to install at least two connecting sleeves 2 in a way that the mounting plates 23 are located in the same horizontal plane. Then, install the support plate 3 on one side on the mounting plate 23 on a connecting sleeve 2, and place the support frame 4 reasonably on the support block of the support plate 3. Under the action of the support rod 41 and the support block 31, the mounting frame is initially fixed, and then another support plate 3 is installed and fixed on the mounting plate 23. After tightening the bolts to strengthen the connection of the connecting sleeve 2, the installation is completed. After the construction of the bridge is completed, the bridge can not only be supported by the bridge column 1, but also by the support plate 3 made of D406A high-strength steel, which greatly improves the support and reinforcement effect of the bridge, and improves the safety and life of the bridge.
