Embodiment 1

[0042] Such as figure 1 , 2 As shown, a reinforcement structure for a beam-column support foundation, the reinforcement structure is arranged on the periphery of the foundation 1, including a reinforcement assembly 2 and a support assembly 3, the reinforcement assembly 2 is connected to the foundation 1, and the reinforcement assembly includes a reinforcement pile component 21 and The first enlarged foundation 22 connected with the reinforced pile part, the reinforced pile part 21 includes a plurality of reinforced piles 211 arranged along the circumference of the foundation 1, the first enlarged foundation 22 is arranged on the top of the reinforced pile part 21, the first enlarged foundation 22 is In the overall structure, the support assembly 3 is arranged outside the reinforcement base assembly 2 , the support assembly 3 includes a support pile component 31 , and the support pile component 31 includes a plurality of support piles 311 arranged along the circumference of the...

Embodiment 2

[0046] Such as image 3 , 4 As shown, a reinforcement structure for a beam-column support foundation, the difference between this embodiment and Embodiment 1 is that the support assembly 3 includes a support pile part 31 and a support frame 32, and the support frame 32 and the support pile part 31 and a reinforcement assembly 2 connection, the support frame 32 is an integral structure, the support frame 32 is a concrete member, and a steel mesh is arranged in the concrete member, the steel mesh is arranged horizontally, and there is at least one layer, and the strength of the support frame 32 is greater than or equal to C30 concrete. The top surface of the support frame 32 is flush with the top surface of the foundation 1 . The foundation 1, the reinforcement component 2 and the support component 3 form an integral structure.

Embodiment 3

[0048] Such as Figure 5 , 6 As shown, a reinforcement structure for a beam-column support foundation, the difference between this embodiment and Embodiment 1 is that the support assembly 3 includes a support pile part 31 and a support frame 32, and the support frame 32 and the support pile part 31 and a reinforcement assembly 2 connection, the support frame 32 is not an integral structure, the support frame 32 includes several support beams 321 arranged horizontally, the support beams 321 are concrete members, and each support beam 321 connects each support pile 311 with the first enlarged The foundation 22 is connected to realize the overall connection of the reinforcement component 2 and the support component 3 .

Abstract

The invention discloses a reinforcing structure used for a beam column type bracket base and a construction method thereof. The reinforcing structure is arranged at the periphery of the base, and comprises a reinforcing assembly and a supporting assembly, wherein the reinforcing assembly is connected to the base; the reinforcing assembly comprises a reinforcing pile part and a first expanding baseconnected to the reinforcing pile part; the first expanding base is arranged on the top of the reinforcing pile part; the first expanding base is of an integral structure; the supporting assembly isarranged at the outer side of the reinforcing assembly; and the supporting assembly comprises a supporting pile part. In case of not dismounting the original bracket, the reinforcing structure reinforces a bracket system base; and the reinforcing structure and the base define an integral stress structure, so that integral stability of the base is improved, and the whole bracket system meets stressrequirements.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a reinforcement structure and a construction method for beam-column support foundations. Background technique [0002] With the rapid development of bridge construction, bridge construction varies according to the address and environmental factors of the bridge. Lightning-beam composite support method, etc. Among them, the beam-column support has the advantages of meeting the requirements of vehicle traffic and navigation in the construction of box girders across roads and rivers, and has the advantages of short construction period, less materials and labor, stable foundation, and small settlement. Widely used, the use of beam-column support can avoid large-scale foundation treatment and reduce personnel input. [0003] The beam-column support structure is composed of foundations, piers, longitudinal beams, beams, formwork and other parts. During the construction process, the b...
