Embodiment Construction

[0023] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0024] Please refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , the present invention provides a new type of steel spring floating plate sealing strip, including an inner seal assembly 1 and an outer seal assembly 2, the inner seal assembly 1 is vertically connected to the middle of the outer seal assembly 2; the inner seal assembly 1 is an inverted cone structure.

[0025] The present invention adopts inner and outer two-layer sealing components, uses the inner sealing component 1 to embed into the gap, and fills in the gap, thereby buckling the floating plate from the inside, preventing the sealing strip from falling, and sealing the gap from the inside, using the outer sealing component 2 Close to the outer wall of the gap from the outside of...

Abstract

The invention provides a novel steel spring floating slab sealing strip which comprises an inner sealing assembly and an outer sealing assembly, and the inner sealing assembly is vertically connected with the middle of the outer sealing assembly; and the inner sealing assembly is of an inverted cone structure. According to the sealing strip, subway site construction is facilitated, the workload of batch drilling during traditional sealing strip installation is reduced in a press-in installation mode, the sealing strip is in an extrusion shape, production and machining are convenient, the inverted cone structure is adopted, installation is firm, and attachment is convenient.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a novel steel spring floating plate sealing strip. Background technique [0002] With the continuous expansion of the city scale, especially the central big cities, more and more cities are building subways. With the development of the first- and second-tier metropolitan circles, the subway construction of these central cities has also expanded to the surrounding neighboring cities. Urban rail transit is developing rapidly, and nearly 40 cities across the country have carried out subway construction. [0003] In urban rail transit, in order to effectively reduce the impact of vibration and noise on the surrounding environment when subway trains are running, rail vibration isolation systems are often used to achieve the purpose of reducing vibration and noise. A large number of engineering practices in the field of rail transit have proved that the floating slab track...
