Description
Technical field
The present invention relates to a kind of template construction method, particularly a kind of template construction method of heating furnace furnace wall.
Background technology
General water beam, flue, chimney, hot-air duct and the insulation in furnace body, stove of the furnace lining of smelting and heating system
Used in several process procedures such as hole.Wherein core process link is furnace body and flue, accounts for total system furnace lining workload
More than 70%.Furnace lining can be divided into furnace roof, furnace bottom, the part of furnace wall three, and wherein furnace wall is using thermal insulation layer and the mixing furnace lining of working lining
Structure, working lining is generally with castable or moldable, it is necessary to carry out template support (requisite measure of construction).
In existing furnace wall work progress, moldable working lining generally shores the mold method of steel form using scaffold tubes：
Supported with common scaffold, scaffold tubes cross-brace is between both walls, and operating space is small when moldable transport and construction；Pin
Hand pipe laterally withstands forces relatively small, and not only quantity is big with scaffold tubes for formwork, and swollen mould phenomenon (template is easily produced in work progress
Rigidity not enough, reinforce loosely or off-design drawing), and scaffold tubes castable be difficult carry out large area cast, construction speed
It is slower.Castable working lining supports the mold method of steel form using I-steel：Supported, grasped using punching block supporting with I-steel
Make easy, but punching block board size is more compared with small splicing seam, but it is more to be often repeatedly used in turn rear damaged surfaces, is poured after causing construction
Material feeding surface smoothness and sensorial effects are poor；I-steel peace, which tears open to drive a vehicle, to be lifted, and all uses I-shaped bracing members, prop up,
I-steel lifting amount is larger during form removal, and driving limited amount, constrains construction speed in factory building.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of template construction method of heating furnace furnace wall, work progress is solved
In swollen mould phenomenon, increase operating space, accelerating construction progress.
In order to solve the above-mentioned technical problem, the invention provides a kind of template construction method of heating furnace furnace wall, including stove
Wall thermal insulation layer is constructed and boiler brickwork layer construction：
S1：For using moldable boiler brickwork layer construction, selecting polylith steel form；For the furnace wall using castable
Working lining is constructed, selection polylith plank sheathing or steel form；

To the inwall for being horizontally fixed on the heating furnace, the I-steel is provided with multiple first shuttering supporting standpipes, and the scaffold tubes are set
There are multiple second shuttering supporting standpipes；
S3：Furnace wall thermal insulation layer is built by laying bricks or stones in the inwall of the heating furnace；
S4：For using moldable boiler brickwork layer construction, from bottom to top successively by the template erection corresponding
On first shuttering supporting standpipe and the second shuttering supporting standpipe, often set up one layer of template, this layer of template and the furnace wall every
Region between thermosphere carries out boiler brickwork layer ramming construction；
For the boiler brickwork layer construction using castable, each layer template erection is completed from bottom to top, in each layer template and
Region between the furnace wall thermal insulation layer carries out boiler brickwork layer casting and constructing；
S5：The template is removed from top to bottom.
The step S2 includes：The I-steel bottom and Bottom of Heating Furnace are welded and fixed, using angle steel by I-steel
Top and the heating-furnace top solder are fixed.
The step S2 includes：Hole for hoist is opened up at the top of the I-steel, boom hoisting will by the hole for hoist
I-steel is vertically hung to the inwall of the heating furnace, then is welded and fixed.
The step S2 includes：Nut is set on the inwall of the heating furnace, screw rod is arranged on the nut, will
The scaffold tubes are horizontally fixed on the screw rod.
The step S2 includes：Sleeve is set on the screw rod.
Nut in the step S2 is thickeies nut, and the screw rod is Screw arbor with nut at both-ends.
The step S4 includes：The template is fixed on the scaffold tubes with goat's horn fastener.
It is integrated poured using large area to the boiler brickwork layer of the castable in the step S4.
The boiler brickwork layer of the castable is poured into a mould using storehouse method piecemeal is jumped in the step S4.
After the step S5 removes the template, the brushing releasing agent in the template.
Compared with prior art, the beneficial effects of the present invention are：Using I-steel and scaffold tubes mixing support, increase workman
Operating space, improves operating efficiency；While reducing the overall usage amount of I-steel, formwork speed is lifted, significantly shortens the duration.
For the boiler brickwork layer of moldable boiler brickwork layer and castable, successively supporting (erection) template successively ramming is selected respectively
The mode of the integrated poured construction of mode and integer support (erection) template of construction, effectively reduces the generation for the film phenomenon that rises, reduction
Spillage of material, it is ensured that wall lining flatness, the requirement of perpendicularity equidimension, improves construction quality.I-steel of the present invention, pin hand
Pipe and the repeatable recycling of template, energy-conserving and environment-protective, with good economic and social benefit.
