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
The present invention relates to a kind of chimney internal cylinder glass fiber reinforced plastic expansion joint, be used for the flexible position expansion shrinkage-compensating of industry chimney internal cylinders such as thermal power generation power plant, chemical industry, metallurgy, belong to heavy aseptic technic field.
Background technology
Concrete or brick inner core chimney are provided with the expansion joint mostly, this expansion joint deals with very difficulty in the preservative treatment process in later stage, defectives such as seepage appear often, therefore need a kind of simple and reliable processing mode, with the sealing and the flexible problem at effective solution chimney internal cylinder expansion joint, avoid occurring anticorrosion back seepage phenomenon.
Summary of the invention
The glass fiber reinforced plastic expansion joint that the purpose of this invention is to provide a kind of safe and reliable, convenient construction, when remedying old chimney anticorrosion flexible position handle complicated, the present situation of seepage appears easily.
In order to achieve the above object, technical scheme of the present invention provides a kind of chimney internal cylinder glass fiber reinforced plastic expansion joint, it is characterized in that, comprise that at least two "＞" shapes that are parallel to each other are supported spoke, the two ends of "＞" shape support spoke are fixed on the both sides at chimney expansion joint on the inner wall of stack by nail, the place, summit that "＞" shape is supported spoke links together by connecting line, "＞" shape supports spoke and the connecting line outside is fixed with supporting network, the supporting network outside is provided with glass steel shell, and the two ends of glass steel shell are fixed on the inner wall of stack;
Wherein, described supporting network comprises steel wire, is fixed on the glass cloth in the steel wire outside and is fixed on the glass cloth outside "＞" shape and supports glass epoxy on the square region between spoke and the connecting line.
Further, the apex angle of described "＞" shape support spoke is 30 °-120 °.
The present invention makes glass steel shell separate with chimney internal cylinder owing to take the technology of prefabricated supporting network, field fabrication supporting surface, on-the-spot lamination fiberglass, thereby utilizes the toughness of fiberglass to realize the compensation Telescopic.
Advantage of the present invention is:
(1) applied widely: as to can be used for chimney internal cylinders such as concrete, brick.
(2) flexible wide ranges:, can satisfy the requirement of the various strokes of chimney by adjusting the big small-sized shape of "＞" shell body.
(3) basal plane is required low: because that the fiberglass of in-place forming can stick with the matrix of different shape is fine.
(4) good seal performance: because on-the-spot lamination, the fiberglass at two ends well is fixed in chimney internal cylinder and also can finely sticks in the collective surface by the bonding of itself and the peg of spoke, and the tangent plane table can also carry out the anticorrosion of other modes, thereby good seal performance;
(5) speed of application is fast: owing to adopt the way of prefabricated supporting network, greatly reduce the difficulty of field fabrication fiberglass, solved the netted object plane of one spot and be difficult to a married difficult problem with fiberglass, thereby accelerated speed of application;
(6) heatproof, good corrosion resistance, the intensity height.Thereby can produce the glass fiber reinforced plastic expansion joint of various premium properties by selecting different resins and reinforcing material for use.
