Problems solved by technology
[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 Sealing and stretching of joints to avoid leakage after anti-corrosion

Embodiment
[0021] Such as figure 1 Shown is the cross-sectional view of the FRP expansion joint of the chimney inner tube. The chimney inner tube glass fiber reinforced plastic expansion joint is composed of ">" shaped support spokes 3, nails 4, connecting wires 5, support nets 6 and glass fiber reinforced plastic shells 7. The two ends of the ">"-shaped support spoke 3 are fixed on both sides of the chimney expansion joint 2 on the chimney inner wall 1 by nails 4, such as figure 2 As shown, it is a schematic diagram of the connection of the supporting spokes. The vertices of the ">" shaped supporting spokes 3 are connected together by connecting lines 5, and the outer sides of the ">" shaped supporting spokes 3 and the connecting lines 5 are fixed with supporting nets 6, and the outer sides of the supporting nets 6 are provided with Fiberglass shell 7 is arranged, and the two ends of glass steel shell 7 are fixed on the chimney inner wall 1, as Figure 4 Shown is the front view of th...

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 ofthe 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...
