Abstract
The invention discloses an anti-fracturing metal anchorage which comprises a connecting piece and a movable piece. The connecting piece is welded with a power generation boiler metal casing. The movable piece is movably connected with the connecting piece, and is poured in a refractory layer on the inner wall of the power generation boiler metal casing. The connecting piece comprises a substrate and vertical upsiding down edges arranged on two sides of the substrate and perpendicular to the substrate. The two vertical upsiding down edges are welded with the power generation boiler metal casing. A stripped hole is formed in the center of the substrate. The movable piece comprises a horizontal connecting rod. A minor diameter section is arranged at one end of the horizontal connecting rod. A symmetrical bump is arranged at the tail end of the minor diameter section. The minor diameter section is inserted in the stripped hole. The width of the symmetrical bump is larger than the aperture of the stripped hole. A symmetrical concave column is arranged at the other end of the horizontal connecting rod.
Description
Technical field
The present invention relates to electricity generation boiler and build field by laying bricks or stones, particularly relate to flame retardant coating and the electricity generation boiler metallic walls anchoring piece of furnace wall.
Background technology
During current domestic electricity generation boiler is built by laying bricks or stones, owing to furnace wall height is high, brick is easy to fall down when building by laying bricks or stones, so needing to strengthen fixing with metal anchorage, existing commonly used metal anchorage is Y, V-type, and above-mentioned anchoring piece one end is welded with metal shell, and one end is cast in flame retardant coating, it is and is rigidly connected, in use, high temperature causes the STRESS VARIATION that it is interior, stress longitudinally and radially to eliminate, it is easily caused anchoring piece fracture, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of effective elimination shear stress longitudinally and radially, effectively prevent the anti-metal anchorage that fractures that anchoring piece ruptures.
For realizing the object of the invention, provide techniques below scheme: one resists the metal anchorage that fractures, it is characterized in that the connector with the welding of electricity generation boiler metal-back and the movable part being flexibly connected with connector, movable part is cast in the refractory masses of electricity generation boiler metal-back inwall, described connector includes the vertical flange that substrate, substrate both sides are vertical with substrate, two vertical flange weld with electricity generation boiler metal-back, and substrate center offers bar hole；Movable part includes that horizontal brace rod, horizontal brace rod one end are provided with path section, and path section end arranges the projection of symmetry, and path section is inserted in bar hole, and symmetrical bump width is more than the aperture of bar hole, and the horizontal brace rod other end is symmetrically arranged with projection.
As preferably, a length of 80 ~ 120mm of bar hole.
As preferably, horizontal brace rod is strip plate body, and path section is set to cylinder, a length of 30 ~ 50mm of path section.
As preferably, the thickness of strip plate body is 20 ~ 30mm.
As preferably, projection center offers the counter sink that the degree of depth is 8mm.
The method have the benefit that the present invention by being divided into two parts of flexible connection by anchoring piece so that it is there is displacement space the most radially and longitudinally, eliminate shearing stress, greatly strengthen its anti-intensity that fractures, so that furnace wall is more firm.
