Abstract

The invention relates to a manufacturing method of a vibration-isolating rubber bearing for building, which adopts a mould to make internal steel plates and internal rubber by pressing to form an internal rubber and internal steel plate composite layer and an internal rubber, internal steel plate and internal rubber composite layer, and the size is precise and the thickness error is 0.05mm. The invention solves the offset problem of the internal steel plates, and simultaneously no residual rubber is removed; no air is generated in the process of curing mold, so no air needs to be exhausted. Since the rubber protective layer of the vibration-isolating rubber bearing for building adopts an injection rubber process, the rubber protective layer of the vibration-isolating rubber bearing for building can adopt more anti-aging special rubber different from the internal rubber, such as EPDM rubber, halogenated butyl rubber, mixing polyurethane rubber and the like, thereby improving the quality and service life of products.

Description

Technical field: [0001] The invention relates to a building vibration isolation rubber support and a manufacturing method thereof, in particular to a natural rubber used as an internal rubber building vibration isolation rubber support and a manufacturing method thereof. Background technique: [0002] The existing building vibration isolation rubber bearings are generally composed of two-layer sealing steel plates with connecting holes, multiple internal rubbers, multiple internal steel plates, and rubber bearing protective layers. Generally, the existing building rubber shock-isolation bearings are manufactured by molding. The internal steel plate of the product manufactured by the existing molding method will be offset. The reason for the offset is that the single-layer internal steel plate and the single-layer internal rubber are sequentially placed into the vulcanization mold cavity. In the initial stage of the external pressure molding vulcanization process, the internal rub...
