Description
Technical field
The present invention relates to industrial building Steel Structure Installation field, specifically relate to a kind of detachable assembly platform and furnace shell welding aligning method.
Background technology
In industrial building Steel Structure Installation field, blast furnace and hot-air stove shell are generally transported to erecting bed again in factory's burst making and install.For ensureing in-site installation progress and quality, need on the ground the furnace shell of sheet to be carried out assembled after, then carry out integral hoisting.But, at present for the platform structure of assembling, mainly there is complex structure, cannot recycle, levelling difficulty causes the defects such as welding precision is lower.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide that a kind of structure is simple, convenient disassembly, can to recycle and levelling easier furnace shell welding centering platform, can disassembly and assembly platform.Meanwhile, present invention also offers a kind of furnace shell welding aligning method.
To achieve these goals, the technical solution adopted in the present invention is: a kind of detachable assembly platform, and this assembly platform is made up of girder, secondary beam and inner circle part; Girder has some, and arranges along inner circle part central point with annular array; Connected by some secondary beams between adjacent girder, form circular ring to be supported by girder in the outside of inner circle part by secondary beam.
Described girder selection model is the H profile steel web of H294*200*8*12, and secondary beam selects I20 steelframe, and inner circle part selects annular I-steel; Secondary beam end stretches into girder inside, and it is inner that end of main beam stretches into inner circle part, and three top flushes; The installing plate being placed in girder inside is that girder and secondary beam are connected and fixed by the bolt of M20 by model; The installing plate being placed in inner circle part inside is that girder and inner circle part are connected and fixed by the bolt of M20 by model.
The method of furnace shell welding centering, step is as follows:
1), in the assembling concrete place of assembling cast in situs 20m*20m, or, do not build, directly levelling then compacting;
2), at place central point set aside pre-embedded part, then start assembled assembly platform, first set up level meter, inner circle part is welded with built-in fitting;
3), first screw in bolt girder, secondary beam and inner circle part are assembled, control its absolute altitude error by level meter, then tight a bolt, complete the assembled of assembly platform;
4), according to the radius of furnace shell, temporary weld stopper slot on girder, puts into stopper slot by the furnace shell of sheet;
5), furnace shell interior welds fixing card more than two, connect furnace shell and assembly platform by M30 wire tensioner;
6), by above-mentioned steps, furnace shell by preliminary centering, then by level meter and centerline approach, control furnace shell diameter and concentricity within the scope of tolerance after, finally weld to form toroidal shell to sheet furnace shell.
Detachable assembly platform of the present invention and furnace shell welding aligning method, its beneficial effect shows:
Because Platform Designing becomes pin-connected panel, the time of erecting bed can be reduced like this, simultaneously because can repeatedly use, thus reduce construction cost, add the competitiveness in market.Assembly platform structure is simple, and it is convenient to remove, and is easy to manufacture and keeping.Be applicable to installation period short, install unit price lower when consider.
Carry out furnace shell welding centering by this detachable assembly platform, both ensure that the installation quality of furnace shell, and in turn ensure that the assembled speed of furnace shell, decrease the manpower consumption that furnace shell is assembled simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of detachable assembly platform.
Fig. 2 is the sectional view at A place in Fig. 1.
Detailed description of the invention
For further describing detachable assembly platform of the present invention and furnace shell welding aligning method, below in conjunction with accompanying drawing, it is described in further detail.
Refer to Fig. 1 and 2, a kind of detachable assembly platform, is made up of girder 3, secondary beam 2 and inner circle part 1; Girder 3 has some, and arranges along inner circle part 1 central point with annular array; Connected by some secondary beams 2 between adjacent girder 3, form circular ring to be supported by girder 3 (being similar to spider web shape) in the outside of inner circle part 1 by secondary beam 2.
Described girder 3 selects model to be the H profile steel web of H294*200*8*12, and secondary beam 2 selects I20 steelframe, and inner circle part 1 selects annular I-steel; It is inner that girder 3 is stretched in secondary beam 2 end, and it is inner that inner circle part 1 is stretched in girder 3 end, and three top flushes; The installing plate 5 being placed in girder 3 inside is that girder 3 and secondary beam 2 are connected and fixed by the bolt 4 of M20 by model; The installing plate 5 being placed in inner circle part 1 inside is that girder 3 and inner circle part 1 are connected and fixed by the bolt 4 of M20 by model.
Girder length dimension is determined according to blast furnace and hot-blast stove, such as: when blast furnace is 650m
3to 1080m
3during blast furnace, girder peripheral diameter 10m just meets the demands.If furnace capacity becomes large, the just corresponding increase of the corresponding size of girder.
Utilize this detachable assembly platform to carry out the method for furnace shell welding centering, be specially:
In the assembling concrete place of assembling cast in situs 20m*20m, or, do not build, directly levelling then compacting.At place central point set aside pre-embedded part, then start assembled assembly platform, first set up level meter, inner circle part 1 is welded with built-in fitting.First screw in bolt 4 girder 3, secondary beam 2 and inner circle part 1 are assembled, control its absolute altitude error by level meter, then tight a bolt, complete the assembled of assembly platform.
Because platform is all bolted substantially, once after on-the-spot platform builds, less people just can be arranged to start immediately to carry out assembled (decreasing the processes such as the buying of auxiliary material, picture, blanking, making).Furnace shell is assembled on this platform simultaneously, decreases the relative elevation deviation that furnace shell is assembled.When furnace shell is assembled on assembly platform, first according to the radius of furnace shell, temporary weld stopper slot on platform girder, puts into stopper slot by the furnace shell of sheet.The fixing card of every sheet furnace shell interior welds two groups, connects furnace shell and assembly platform by M30 wire tensioner, can regulate the perpendicularity of furnace shell like this, prevent furnace shell from collapsing (each furnace shell necessarily requires more than two being fixed) simultaneously.
Through above step, the preliminary centering of furnace shell, then by the method such as level meter and center line, control furnace shell diameter and concentricity within the scope of tolerance after.Finally weld to form toroidal shell to sheet furnace shell.
Namely be ensure that the installation quality of furnace shell by above step, in turn ensure that the assembled speed of furnace shell.Decrease the manpower consumption that furnace shell is assembled simultaneously.In assembled process, ensure that girder top absolute altitude is consistent by level meter.When after the assembled end of furnace shell, remove immediately.Be convenient to protection like this.When next building site needs, can use rapidly.By the measure cost that each blast furnace etc. is installed can be reduced after repeatedly using, realize cost efficiency.
Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
