Description
Technical field
The present invention relates to the buckstay device of boiler, be specifically related to a kind of truss buckstay device for boiler.
Background technology
Boiler buckstay is around and is suspended on boiler wall periphery, the steel structures coating shielding furnace wall.It
Effect be to strengthen burner hearth and the rigidity of back-end ductwork, reduce the vibration of pipe wall, protection pipe allows pressure in boiler maximum instantaneous
Under power effect without damage.Buckstay can be divided into spirally-wound type and grid type two class, and China typically now uses band-wound rigid beam.
The load of band-wound rigid beam effect is the expansive force of boiler, expansive force be due to the artificial Expansion Center of boiler with naturally expansion in
The heart is inconsistent and produces (suspention boiler furnace expansive force see table).
The intensity of buckstay need to use allowable stress method, allowable stress σ=0.6fy.Under furnace enclosure design pressure, buckstay
Stress must not exceed allowable stress；Under burner hearth maximum instantaneous allows pressure, the stress of buckstay is up to yield limit；Weldering
The buckstay adnexa received on pressure parts should leave enough allowances.Buckstay when furnace pressure is 2KPa, buckstay
Relative Deflection cannot be greater than 1/360.It is main for typically using I-steel, H profile steel or steel plate splicing structure during Design of Buckstay, right
Select I-steel cross section in the horizontal stiffness beam routine that span is less, but the horizontal stiffness beam for large span needs to choose
H profile steel or large-scale steel plate splicing beam, this part buckstay cross section is big, conducts oneself with dignity heavier, causes load big heating surface tube group.Just
Property beam design time should meet the furnace expansion power requirement of boiler, the intensity of buckstay to be met, rigidity and amount of deflection requirement.Institute
With when designing relatively cauldron buckstay, the horizontal buckstay of boiler is for meeting requirements above, and its cross section is the biggest, heavier-weight,
Heating surface tube group is caused certain load, and material is caused certain waste.
Summary of the invention
The present invention is relatively big for solving the cross section of existing boiler buckstay, and steel consumption is big, conducts oneself with dignity heavier, to water-cooling wall and bag
The problem of the heavy load of wall, and then a kind of truss buckstay device for boiler is provided.
The present invention solves that above-mentioned technical problem adopts the technical scheme that:

Adjacent two set corners connect to connect between assembly a steel I-beam, two channel-section steel formula truss, two steel I-beams and four groups
Corner connects assembly and connects and composes quadra structure.
The invention has the beneficial effects as follows: one, present configuration design science is reasonable, the present invention uses truss form, with relatively
The channel-section steel of small dimension, as the housing of truss, collectively constitutes truss with small dimension I-steel and small dimension channel-section steel, with this truss generation
For big specification H profile steel and the buckstay of steel plate splicing structure, reduce steel consumption, play minimizing heating surface load and reduce cost
Effect.This truss buckstay can use different composite types according to different situations, at structure constraint and limited space
Time, can reasonably adjust the specification of the medium and small shaped steel of truss to adjust the width of total, the design of relatively conventional rigid beam has
Higher motility.
Two, reinforcing beam corner junction novel connecting form in the present invention, uses one block of attachment strap and some reinforcing plates
Structure is connected on the frame of truss, the side of truss weld one block of common steel plate and connecting plate combination be fixed on water-cooling wall or
On back-end ductwork bag wall, more favourable and raising integral rigidity, it is more uniformly stressed.
Three, the present invention is cheap for manufacturing cost compared with prior art, saves the manufacturing expense of more than 30%.The present invention pacifies
Quan Xinggao, has motility, polygon, and the present invention is easy to use, applied widely.
