Description
Technical field
This utility model be related to boiler rigid boom device and in particular to a kind of for boiler truss rigidity boom device.
Background technology
Boiler buckstay is around and is suspended on boiler wall periphery, the steel structures coating that furnace wall is shielded.It
Effect be the rigidity strengthening burner hearth and back-end ductwork, reduce the vibration of pipe wall, protection pipe allows pressure in boiler maximum instantaneous
Without damage under power effect.Buckstay can be divided into spirally-wound type and grid type two class, and China typically now adopts band-wound rigid beam.
Band-wound rigid beam effect load be boiler expansive force, expansive force be due to the artificial Expansion Center of boiler with naturally expansion in
The heart is inconsistent and produce (suspention boiler furnace expansive force see table).
The intensity of buckstay need to adopt allowable stress method, allowable stress σ=0.6fy.Under furnace enclosure design pressure, buckstay
Stress must not exceed allowable stress；Allow under pressure in burner hearth maximum instantaneous, the stress of buckstay is up to yield limit；Weldering
The buckstay adnexa being connected on pressure parts should leave enough allowances.Buckstay when furnace pressure is for 2kpa, buckstay
Relative Deflection cannot be greater than 1/360.Typically adopt based on I-steel, H type steel or steel plate splicing structure during Design of Buckstay, right
Select I-steel section in span less horizontal stiffness beam routine, but the horizontal stiffness beam for large span needs to choose
H type steel or large-scale steel plate splicing beam, this partly rigid beam section big, deadweight is heavier, causes load big heating surface tube group.Just
Property beam design when should meet the furnace expansion power of boiler and require, also the intensity of buckstay to be met, rigidity and amount of deflection require.Institute
So that when design is compared with cauldron buckstay, the horizontal buckstay of boiler is to meet requirements above, and its section is all larger, heavier-weight,
Heating surface tube group is caused with certain load, and material is caused with certain waste.
Utility model content

It is connected with a steel I-beam, two channel-section steel formula truss, two steel I-beams and four groups between adjacent two sets of corner coupling assemblies
Corner coupling assembly connects and composes quadra structure.
The beneficial effects of the utility model are: one, rationally, this utility model adopts purlin to this utility model scientific structure design
Frame form, with the channel-section steel compared with small dimension as the housing of truss, collectively constitutes truss with small dimension I-steel and small dimension channel-section steel,
Replace the buckstay of big specification H type steel and steel plate splicing structure with this truss, reduce steel consumption, play minimizing heating surface load
And the effect of reduces cost.This truss buckstay can adopt different composite types according to different situations, structure constraint with
And during limited space, can reasonably adjust the specification of little shaped steel in the truss width to adjust total, compared with conventional rigid
Beam design has higher motility.
2nd, reinforcing beam corner junction novel connecting form in this utility model, using one block of attachment strap and some reinforcements
The structure of plate is connected on the frame of truss, and side one block of common steel plate of welding of truss is combined with connecting plate and is fixed on water-cooled
On wall or back-end ductwork bag wall, so more favourable and raising integral rigidity, it is more uniformly stressed.
3rd, this utility model is cheap for manufacturing cost compared with prior art, saves more than 30% manufacturing expense.This reality
High with new type of safe, there is motility, polygon, this utility model is easy to use, applied widely.
