Description

Forging machine damping cast-in-situ concrete foundation formwork support system and construction method Technical Field The invention relates to the technical field of constructional engineering, in particular to a vibration-damping cast-in-situ concrete foundation formwork support system of a forging machine and a construction method. Background In the field of heavy machinery manufacturing, forging machines are used as core production equipment, and their normal operation relies on a robust and reliable equipment foundation. Because the forging machine generates huge impact load and vibration in the working process, the foundation of the forging machine is generally designed into a damping structure, and the vibration is isolated from being transmitted to the surrounding civil engineering structure by arranging a damper, so that the equipment precision and the service life are ensured. The damping foundation generally comprises a foundation slab, a peripheral shear wall, a damper, a floating block, a bracket for connecting the shear wall and the floating block and other functional components, and has the advantages of complex structure and extremely high construction precision requirement. Currently, for formwork construction of large-volume concrete foundations, an all-steel formwork system or a traditional wood formwork system is generally adopted. However, for projects with special construction requirements such as forging machine damping foundations, the existing formwork support technology has the following defects: Firstly, the construction support and the permanent shock absorption function are difficult to coordinate. The core of the damping foundation of the forging machine is that the floating blocks are finally supported by the dampers so as to realize the vibration isolation effect. However, in the construction stage, when the damper is not loaded, the large-volume concrete pouring of the floating blocks needs a temporary supporting system to provide stable support. In the prior art, the temporary support and the permanent shock absorber cannot be coordinated and arranged at the same elevation, so that a support system needs to be adjusted repeatedly in the construction process, or the stable transfer of load to the shock absorber is difficult to realize after concrete pouring, and the shock absorption effect is affected. Secondly, the molding precision of key parts is difficult to ensure. The bottom surface of the floating block is directly contacted with the shock absorber, and the flatness and the elevation precision of the floating block directly influence the stress uniformity and the equipment operation stability of the shock absorber. The bracket is used as a key force transmission component for connecting the shear wall and the floating block, and the forming quality of the bottom surface of the bracket is also important. The traditional template system is difficult to provide enough rigidity and precision control in the construction of the cantilever structure and the large-area bottom die, and the problems of elevation deviation, insufficient flatness and the like are easily caused after concrete is formed, so that the stress performance of the structure is affected. Thirdly, the complex node template is difficult to prop up. At the junction between the shear wall and the slider, the corbel structure tends to be overhanging, and the fixation and support of the bottom formwork lacks reliable stress points. In the prior art, the node templates are often supported by full scaffold or temporarily suspended, so that the construction efficiency is low, the stability is poor, and the safety risks of template deformation, template running and even collapse exist. Fourth, the process cross interference is much, and the construction period is long. In the traditional construction method, multiple working procedures such as foundation slab, shear wall, shock absorber installation, floating block construction, bracket construction and the like are often mutually interfered, the follow-up operation can be carried out after the preceding working procedures reach a certain strength, and a template supporting system among the working procedures is difficult to cooperate, so that the construction period is prolonged, and the management is complex. In order to solve the above problems, it is needed to develop a formwork support system and a matched construction method which are specially suitable for a forging machine to damp cast-in-situ concrete foundation, so as to coordinate construction support and permanent damping functions, ensure the forming precision of key parts, simplify complex node construction, and improve the overall construction efficiency and quality. Disclosure of Invention In view of the above, the invention provides a vibration-damping cast-in-situ concrete foundation formwork support system of a forging machine and a construction method, which aim to solve the problems that the
