Abstract

The invention relates to a double-sealed sound and heat insulating floor maintenance cover, which comprises a maintenance frame, a sound-insulating rubber layer, a noise-reducing spongy layer and a perforated aluminum net, wherein the sound-insulating rubber layer, the noise-reducing spongy layer and the perforated aluminum net are arranged in the maintenance frame, the sound-insulating rubber layer is at the upper part of the maintenance frame, the noise-reducing spongy layer is arranged under the sound-insulating rubber layer, and the perforated aluminum net is arranged under the noise-reducing spongy layer. Compared with the prior art, the double-sealed sound and heat insulating floor maintenance cover provided the invention has the advantages of being simple and convenient to assemble and being capable of saving the assembling time and enhancing the production speed of a production line. The double-sealed sound and heat insulating floor maintenance cover adopts a double-sealed structure and fine workmanship, has favorable sealing performance and is in close fit with a maintenance port, so that the sealing performance and the sound and heat insulating performance of the maintenance cover are greatly enhanced. The maintenance cover is modularized, thus being favorable to purchase and store management. Moreover, the maintenance cover is standard in specification, thus saving the production flow.

Description

technical field [0001] The invention relates to a bus floor fitting, in particular to a double-seal sound-insulation and heat-insulation floor maintenance cover. Background technique [0002] At present, the inspection port of the urban bus floor is a simple single-layer sealed structure. The inspection port is tailor-welded, and the sealing structure is sealed with a single-layer rubber strip; the inspection cover is a wooden floor with aluminum profiles and an iron sheet cladding structure. The operation of this structure is time-consuming, the process is rough, the product is made on site, the manufacturing precision is low, the sealing effect is poor, and it is easy to produce deviations between the inspection port and the inspection cover, which cannot meet the heat insulation and noise reduction requirements of the floor inspection port. Contents of the invention [0003] The object of the present invention is to provide a double-seal sound-insulation and heat-insula...
