Chimney internal cylinder glass fiber reinforced plastic expansion joint

Abstract

The technical scheme of the invention provides a chimney internal cylinder glass fiber reinforced plastic expansion joint which is characterized by comprising at least two parallel support spokes shaped like greater-than signs, wherein both ends of support spokes shaped like greater-than signs are fixed at the positions at both sides of a chimney shrinking seam on the inner wall of a chimney by nails; the peak positions of the support spokes shaped like greater-than signs are connected into a whole by a connecting wire; a support mesh is fixed at the outer sides of the support spokes shaped like greater-than signs and the connecting wire and comprises a steel wire mesh, a glass cloth fixed at the outer side of the steel wire mesh and a glass steel plate which is fixed at the outer side of the glass cloth and corresponds to the position between the support spokes shaped like greater-than signs and the connecting wire. The invention has a shrinking compensation function and the characteristics of seal, corrosion resistance, endurance and convenient construction.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic expansion joint in a chimney inner cylinder, which is used for expansion and contraction compensation of the expansion and contraction parts of the chimney inner cylinder in thermal power plants, chemical industry, metallurgy and other industries, and belongs to the technical field of heavy anticorrosion. Background technique [0002] Concrete or brick inner tube chimneys are mostly equipped with expansion joints, which are very difficult to deal with in the later anti-corrosion treatment process, and defects such as leakage often occur. Therefore, a simple and reliable treatment method is needed to effectively solve the expansion and contraction of the inner tube of the chimney The closure and expansion of the seam can avoid leakage after anti-corrosion. Contents of the invention [0003] The purpose of the present invention is to provide a safe, reliable and convenient construction of FRP ex...
