Specific embodiment
It runs derrick dislocation template idea of the invention is that overcoming the deficiencies of the prior art and provide a kind of chimney stalk
Inside-out formulation construction method, construction method is simple and easy, shortens the duration, even more significantly reduces security risk and engineering
Cost.
It is described in detail below with reference to embodiment referring to attached drawing, to be carried out more to technical characteristic of the invention and advantage
Deep annotation.
It is of the invention as shown in Figure 1, the present invention is run derrick dislocation template inside-out formulation construction method using chimney stalk,
Include the following steps；
Step a builds basic chimney shaft 1；
Step b sets up and rises derrick 2 and lifting system；
Step c sets up first layer platform on basic chimney shaft；
Step d checks chimney centralized positioning size again；
Step e, chimney shaft reinforcement installation；
Step f, template system installation, first installs exterior sheathing 3, then install inner template 4；
Step g sets up second layer platform on the template system being installed, and after second layer platform building is good, carries out mixed leaching soil
It pours,
Lifting system is risen one layer along derrick is risen, is repeated in step d, e, f, g operation by step h；
Step j is removed and is risen derrick, lifting system and platform, completes construction, and plugging construction hole.
If Fig. 1-7 is specially work progress are as follows: carry out engineering survey, build 1.6 meters high of basic chimney shaft；It is constructed
Afterwards, the rising derrick that construction height is 125 meters in chimney barrel is specifically set up using 48*3.6 steel pipe scaffold；Lifting system
It is mounted on and rises on derrick, lifting system will be built wooden springboard etc. needed for the first platform and be promoted onto basic chimney barrel, pass through
Iron wire binding and fixing build first layer platform on rising derrick on basic chimney shaft；Again review chimney center is fixed
After the size of position, then by lifting system by chimney shaft reinforcing bar, template system etc. is promoted onto first layer platform, installs external mold
It after plate and inner membrance, is built on template system on second layer platform, lifting system will carry out in mixed leaching soil promotion to the second platform
It pours, completes level-one chimney shaft and pour；
Lifting system is lifted up one layer, reinforcing bar is promoted to progress chimney shaft reinforcing bar peace on the second platform by lifting system
Exterior sheathing after fractionation is integrally lifted up after one layer row assembling again after inner membrance disassembly by lifting system and passes through promotion by dress
System improving turns as new inner membrance to the second platform, while the first platform being promoted on the inside and outside template system newly assembled
Fang Hou, then the inside and outside template system newly assembled is poured, the chimney body for completing upper level pours；The chimney shaft
It is provided with plug-in ladder 12.Plug-in ladder upper end, which is fixed on, to be risen on derrick, chimney barrel outer wall is suspended on, for carrying work
People is convenient for the external template construction of worker.
It repeats the above process, lifting system is promoted along derrick is risen, and the first and second platform alternately moves up, and exterior sheathing is whole
Fractionation assembles after moving up, and inner membrance disassembly turns into new inner membrance, until removing after reaching chimney height and rising derrick, promote system
System and platform complete construction, and plugging construction hole.
As shown in figure 5, the specific manufacturing process of exterior sheathing are as follows: exterior sheathing selects material, and stack shell external mold is all made of 2mm thickness, wide
The thin aluminum top of a length of 1000 × 2000mm is made；Calculate contracture ratio, according to the diameter of chimney and shrinkage rates with CAD into
Row setting-out, calculates shrinkage rates；Exterior sheathing processing and fabricating, four groups of template point are processed, and every group of template reserves 1m on both sides
Contracture side, every aluminum alloy pattern plate processed by calculated shrinkage ratio degree, 1.9 meters of every section height, using circle between plate and plate
Hook bolt and U-shaped fixing card are attached, spacing 110mm, anchor bolt from inside to outside on, make concordant inside template；At every group
The top of plate uses the reinforcing bar of Φ 14, installation climbing shuttering hook every 2m spacing (i.e. every one block of plate)；It is inside and outside to ensure
The clear spacing of mould, and thickness is protected, stainless steel round steel 5, stainless steel are welded on the corresponding stack shell reinforcing bar of exterior sheathing upper/lower terminal
Round steel end rests against on the inside of thin aluminum top, and spacing along the circumferential direction every 300mm mono- is arranged in stainless steel round steel；Sub- external mold board group
It after the completion of dress, is centered around outside stack shell reinforcing bar, the U-shaped fixing card of steel wire penetrating, both ends are controlled using clamping screw, pour concrete
When fasten external mold；Hook is connect with lifter, with lifter that external mold is uniform section by section after concrete reaches strength of mould stripping 1.2N/mm2
It is promoted.
Such as Fig. 2, the lifting system includes interior derrick 6, portal frame lifting beam 7 and pulley blocks 8, the interior derrick
It is mounted on and rises on derrick, portal frame lifting beam is fixedly mounted on interior derrick, and pulley blocks are mounted in portal frame lifting beam, sliding
Wheel group includes top sheave 9 and turning pulley 10, and wirerope connect around pulley blocks with hoist engine；Interior derrick middle position reserves
Square hole 11 of the 0.9m × 0.9m as channel；It is provided with guide rail below the square hole, is slidably fitted with loading plate on guide rail；Dress
There is the carrying ladle of reinforcing bar, mixed leaching soil etc. to be placed on loading plate, is moved to below square hole along guide rail, wirerope and carrying ladle connect
It connects, corresponding height is promoted by hoist engine, for constructing；Springboard, small handcart or other materials can also pass through
Hoist engine is promoted.
The present invention is existed compared with the construction method of traditional chimney stalk using scaffold using the construction method used
The form that lower channel, job platform and material hoisting system are set up inside chimney promotes exterior sheathing plate, to inner template
Plate carries out reverse mould installation, and the factors such as overcoming high altitude operation, difficulty of construction is big, and construction risk is big ensure that the same of construction period
When, so that construction quality is effectively controlled, substantially increases surface smoothness, entity quality and impression quality.
