Abstract
The utility model relates to a truss device that is used for cigarette wind channel to bear subordinate's economizer. To reform transform the in -process in some engineerings at present, often to appear because nervous the take root condition of difficulty of subordinate's economizer that leads to in space is had to to change the appearance in cigarette wind channel or is required the framework specialty to set up the new roof beam of takeing root specially in order takeing root, the optimum cost of perhaps increasing input can not be accomplished in the design that so often makes cigarette wind channel and framework. The utility model discloses the constitution includes: the truss body (1), the truss body including entablature (4), entablature and middle cross beam (7) between respectively the welding have vertical rib (8), diagonal bar (3), connecting plate A (2), connecting plate B (5), middle cross beam and bottom end rail between respectively the welding have vertical rib the diagonal bar connecting plate A connecting plate B, the bottom end rail both sides welded reinforcing plate (9) respectively. The utility model discloses a truss device that is used for cigarette wind channel to bear subordinate's economizer.
Description
Technical field：
The utility model is related to a kind of girder device that subordinate's economizer is carried for cigarette air channel.
Background technology：
At present during some are engineered, Jing often occurs because space anxiety causes subordinate's economizer to be taken root difficulty
Situation, has to change the profile in cigarette air channel to take root or requires that framework specialty specially sets up new beam of taking root, so past
Toward preventing the design of cigarette air channel and framework from accomplishing optimum or cost of increasing input.
Utility model content：
The purpose of this utility model is to provide a kind of girder device that subordinate's economizer is carried for cigarette air channel.
Above-mentioned purpose is realized by following technical scheme：
A kind of girder device that subordinate's economizer is carried for cigarette air channel, its composition includes：Joist body, described joist body
Including entablature, vertical bar, diagonal bar, connecting plate A, connecting plate B are respectively welded between described entablature and middle cross beam, it is described
Middle cross beam and sill between be respectively welded described vertical bar, described diagonal bar, described connecting plate A, described company
Fishplate bar B, described sill both sides are respectively welded reinforcing plate.
The described girder device for carrying subordinate's economizer for cigarette air channel, described joist body bottom is provided with province of subordinate
Coal device erecting by overhang, described subordinate's economizer erecting by overhang is arranged on subordinate's economizer top.
Beneficial effect：
1. the utility model is a kind of girder device and method for designing that subordinate's economizer is carried for cigarette air channel, is passed through
The new truss structure of STAAD.Pro designs, not only can ensure that cigarette air channel is indeformable, and can hang subordinate's economizer, should
Structure can be used in subordinate's economizer be placed on pre-heater inlet flue and framework cannot beam when, hang subordinate's economizer,
And Successful utilization is in the improvement project of state's electricity Shuangyashan.
The utility model is mainly adopted by 14 I-steel, 13 support tubes, 37 pieces of connecting plates compositions, wherein it is upper, in and
Sill adopts I-steel, the Type of Welding between I-steel and connecting plate.
The utility model is calculated through the checking of STADD softwares, it can be seen that I-steel stress sidewards than larger, so
The horizontal I-steel of longer one adopts work № 32a, another horizontal I-steel to reinforce every 400mm distance two pieces of gussets of weldering,
Through calculating support tube Φ 108 × 8, connecting plate need to be adopted to adopt the steel alloy of δ 12.
Description of the drawings：
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of joist body in accompanying drawing 1.
Accompanying drawing 3 is the A-A sectional views in accompanying drawing 2.
Accompanying drawing 4 is the enlarged drawing of B in accompanying drawing 2.
Specific embodiment：
Embodiment 1：
A kind of girder device that subordinate's economizer is carried for cigarette air channel, its composition includes：Joist body 1, described truss
Body includes entablature 4, and vertical bar 8, diagonal bar 3, connecting plate A2, connection are respectively welded between described entablature and middle cross beam 7
Described vertical bar, described diagonal bar, described connecting plate is respectively welded between plate B5, described middle cross beam and sill 6
A, described connecting plate B, described sill both sides are respectively welded reinforcing plate 9.
Embodiment 2：
The girder device for carrying subordinate's economizer for cigarette air channel according to embodiment 1, described joist body bottom
Subordinate economizer erecting by overhang 10 is installed, described subordinate's economizer erecting by overhang is arranged on the top of subordinate's economizer 11.
Embodiment 4：
The Verification method of the girder device that subordinate's economizer is carried for cigarette air channel according to embodiment 1-2,
The method includes following content：
First it is that the truss that will be designed sets up out 3d models, in modeling engineering, flue is modeled due to software
Need to realize designing a model by simplifying piece truss structure complete is limited, makes calculating data truer；
After modeling, need to increase corresponding fulcrum, when fulcrum is selected, the constraint that take into full account fulcrum is released
Put, because whether it is fixing point and the Impact direction and connected mode of the fulcrum that restraint release determines the fulcrum, fulcrum
Selection and fulcrum restraint release it is extremely important to the stability of truss；
After determining fulcrum, need to increase load, load needs to consider many-sided, including dead load, hanging economizer
Load, the load of insulation, load, the internal pressure load of flue inside dust stratification that needs bear, and need to calculate under blowing out state
With the operating mode load under running status；
It is then determined that the material behavior of truss structure each several part, including the material and board of I-steel, support tube, connecting plate
Number, analysis model is performed, finding out vicious place and modeling process in model has where exception, to be corrected, most
Design truss structure according to the checking of software result of calculation afterwards to meet the requirements.
