Description
Technical field
The present invention relates to a kind of anti-expansion bridging arrangement of furnace wall corner flap.
Background technology
Furnace body corner insulation outer casing is typically designed to flap and both sides furnace wall contour plate rivet interlacement, longitudinally about every
Once, that is, flap is directly fixed on furnace wall contour plate to 0.5m nailing, and such set-up mode is although connect fastening, but cannot answer
Furnace wall is expanded.
During unit operation, furnace body easily produces lateral expansion because temperature raises, and its swelling stress mainly acts on corner,
Corner flap cannot tackle expansion because being fixedly connected with both sides furnace wall contour plate nailing, easily causes outer casing to pull open, neither
Attractive in appearance and furnace wall cannot be played a protective role, it is being not easy to operate when keeping in repair to insulation outer casing, maintenance process is very
Loaded down with trivial details.
Content of the invention
The purpose of the present invention is for overcoming above-mentioned the deficiencies in the prior art, providing a kind of flap anti-expansion in furnace wall corner to overlap
Structure, corner insulation outer casing and both sides furnace wall contour plate no follow closely overlap joint, can free wxpansion, it is to avoid furnace wall expands and backplate is drawn
Open.
For achieving the above object, the present invention adopts following technical proposals:
The anti-expansion bridging arrangement of furnace wall corner flap, including insulation outer casing, described insulation outer casing and furnace wall contour plate
Between there is setting gap, and be incubated and be connected by multiple connectors between outer casing and furnace wall contour plate, tool between connector
There is setting spacing；Described furnace wall contour plate edge is connected with support member, and described support member is fixedly connected with limiting plate；Limiting plate
End extend to the outer surface of adjacent insulation outer casing so that limiting plate parallel is set with the adjacent outer surface being incubated outer casing
Put, and there is setting gap between the two, in the vertical direction or horizontal directions mistake are arranged.
Setting gap between outer casing and furnace wall contour plate will be incubated, and the edge of furnace wall contour plate will be passed through support member
Connect limiting plate, limiting plate overlaps to insulation outer casing, between insulation outer casing, limiting plate and furnace wall contour plate all not
Nailing, when unit operation occurs thermal expansion, it is possible to achieve free wxpansion, is not in the phenomenon that insulation outer casing pulls open.With
When limiting plate also can be to insulation outer casing with restriction effect, the expansion more preferably limiting insulation outer casing disconnects.
Preferably, the bottom of described furnace wall contour plate and sidepiece are respectively connected with insulation outer casing, and furnace wall contour plate sidepiece is even
Between the insulation outer casing of the insulation outer casing connecing and the connection of furnace wall contour plate bottom, there is setting gap.By furnace wall contour plate
Sidepiece and bottom are respectively provided with insulation outer casing, and the insulation outer casing of furnace wall contour plate sidepiece and bottom is provided separately, and make
Insulation outer casing outside furnace wall contour plate will not be integrally formed, and preferably tackles the expansion of furnace wall edge.
It is further preferred that described limiting plate is right angle flap, described right angle flap includes first end, pars intermedia and the
Two ends, first end and the second end are vertically set on the two ends of pars intermedia respectively, and first end and the second end from
Contrary by end bearing of trend.
Still more preferably, the first end of described right angle flap and the side of furnace wall contour plate are parallel to each other, right angle
The second end of flap is parallel to each other with the bottom surface of furnace wall contour plate.Limiting plate is arranged to right angle flap, the two of right angle flap
Can be matched with the insulation outer casing of furnace wall contour plate sidepiece and bottom respectively in side, need not be equipped with other structures again
To during furnace expansion, restriction effect is imposed to insulation outer casing.
Preferably, the first end of described right angle flap apart from furnace wall contour plate side apart from a and the second end distance
Furnace wall contour plate bottom surface equal apart from b.The both ends of right angle flap are arranged on away from furnace wall contour plate same distance, more accurate
Really match with insulation outer casing, operating security and stability is strengthened.
Preferably, described limiting plate is 0.5-5mm with the distance between the outer surface of adjacent insulation outer casing.
Preferably, described support member includes first in, pars intermedia and second, first while and be respectively perpendicular setting when second
At the two ends of pars intermedia, and first while and free end bearing of trend when second contrary.
First side of described support member and the side of furnace wall contour plate are parallel to each other, the second side of support member and furnace wall die mould
The bottom surface of plate is parallel to each other.
First side of described support member is fixedly connected with the first end of right angle flap, the second side of support member and right-angle folding
The second end of plate is fixedly connected.Support member is also configured as structure of right angle tyoe, the both sides of support member can respectively with right-angle folding
The both ends of plate connect, and the connection tightness of support member and right angle flap is higher, and connected mode is convenient, can be preferably real
Existing support member and the connection of right angle flap.
The pars intermedia of described support member is connected by connector with the corner of furnace wall contour plate.Connector can be flat
Steel or connecting-rod body.Support member pars intermedia is connected with the corner of furnace wall contour plate, will support member spacing in furnace wall
Edge, when furnace wall expands and produces stress to edge, because support member and furnace wall contour plate are that no nail overlaps, Ke Yishi
Existing free wxpansion, is not in that insulation outer casing is opened；The distance away from furnace wall contour plate for the support member is also outer than insulation simultaneously protects
The distance away from furnace wall contour plate for the plate is farther, and the stress that support member is subject to can reduce, and preferably ensures integrally-built safety.
Described connector is band steel.
The invention has the benefit that
The right angle flap in corner is overlapped using no nail by the present invention with both sides furnace wall contour plate, and right angle flap is directly fixed on
On support member, to the certain distortion allowance of insulation outer casing, effectively prevent backplate expansion and pull open.
The present invention solves the problems, such as that furnace wall corner backplate expands and pulls open, and greatly reduces the probability that backplate breaks down,
Avoid backplate and remove the artificial and waste of material recovering to cause, and construction technology is simple, facilitates implementation.
The present invention will be incubated setting gap between outer casing and furnace wall contour plate, and by outside the insulation outside furnace wall contour plate
Backplate is provided separately, and in the edge setting right angle flap of furnace wall contour plate, and right angle flap is overlapped on outside insulation outer casing
Side, in insulation outer casing, equal not nailing between limiting plate and furnace wall contour plate, when unit operation occurs thermal expansion, Ke Yishi
Existing free wxpansion, is not in the phenomenon that insulation outer casing pulls open.
