Steel structure bridge damping foundation support and preparation method thereof

Abstract

The invention discloses a steel structure bridge damping foundation support and a preparation method thereof. The steel structure bridge damping foundation support comprises an installation seat, a damping air cylinder and a base, the installation seat is located at the upper end of the damping air cylinder, the base is connected to the lower end of the damping air cylinder, a slide rail is arranged in the installation seat, protection plates are arranged above the slide rail, and sliding blocks are connected with the lower ends of the protection plates; the protection plates are slidably connected with the slide rail through the sliding blocks, rotary shafts are connected with the two ends of the slide rail, the sliding blocks are movably connected with the rotary shafts, a telescopic column is in piston connection with the upper end of the damping air cylinder, and a supporting seat is connected with the upper end of the telescopic column. The protection plates are additionally arranged at the two ends of the installation seat to clamp and protect a bridge pier stud when the bridge pier stud is installed, the installation stability is higher, meanwhile, the interior of the installation seat is provided with water seepage holes, the bottom end of the base is provided with a flow guiding groove which can filter and dredge the rainwater and the substrate filtration to some extent, and the situation that the steel structure support bed is corroded by deposit of a water source, and thus the service life and the safety are affected can be avoided.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a steel structure bridge damping base and a preparation method thereof. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields. Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. With the advancement of manufacturing technology, steel Structures ar...

Problems solved by technology

[0003] There are also certain limitations in the installation and use of the shock-absorbing foundation of steel structure bridges. It needs to be constructed in a targeted manner during installation and construction. In order to match the actual bridge piers, it increases the construction cost and time. The cost and engineering quantity are increased, and for the actual construction environment in different regions, the environmental adaptability of the steel structure base is different, and the corrosion resistance effect is uncontrollable, which will affect its service life and safety. Shorter time intervals come with higher labor costs
