Row test run；
Step 8: the casting concrete between inner template 10 and exterior sheathing 11；
Step 9: by hydraulic system and jack, inner template 10 and exterior sheathing 11 are carried out sliding, climbs pour for the first time
When the control of every layer concrete height at 30 centimetres hereinafter, uniformly pouring in four times full, every layer concrete height difference is less than ten centimetres, often
Layer interval time at one hour or so, enter for the first time mould concrete beginning initial rise in three to five hours (view temperature fixed) one to two
Stroke is no more than every time later and mentions a stroke in, prevents template from bonding, guarantee concrete mould unloading strength 0.2~
It is transferred to normal sliding when 0.4Mpa, sliding formwork concrete slump is inserted into lower layer at five centimetres or so, upper layer concrete vibrating
Concrete depth without departing from 50 millimeters, it is sliding in stack shell because self-strength is still in growth, by wind load, equipment and materials weight
The various factors such as amount, frictional force influence, and after the moment has certain shaking, each pouring layer to promote 60 centimetres, are hung with plumb bob
In it is primary, when deviation exceeds ten millimeters, low rectified a deviation immediately, avoid the occurrence of sharp turn phenomenon；
Step 10: assembling reinforcement in the space between inner template 10 and exterior sheathing 11, vertical cutting length are four to six
Rice, when carrying out binding overlap joint, lap of splice 35d, same level nipple number is less than 25%, and circumferential muscle segmentation is in order to wear
Hoisting frame 7 is crossed, the lap of splice is unified；
Step 11: the casting concrete between inner template 10 and exterior sheathing 11；
Step 12: it repeats step 9 and tops out to step 11 until concreting is completed, when carrying out demoulding
Hydraulic-pressure control apparatus is first removed, then removes periphery ring 8, exterior sheathing 11, interior enclosure 9 and inner template 10, then hangs foot inside and outside dismounting
Hand, then lifting means such as dismantling operation platform 5, hoisting frame 7, jack.
It is high to solve high material consumption, danger coefficient that previous stay in place form support system occurs using slipform process
Problem has saved the materials such as a large amount of steel pipe, fastener, big plate, obtains huge economic benefit, while slding form operation speed
Fastly, construction in normal one day can reach three to four meters, and 80 meters of chimneys construction in one month completion ensure that construction speed, comprehensive analysis
Chimney template construction is carried out using this engineering method, it is convenient and efficient, formwork speed is greatly enhanced, has saved manually, has been produced
Raw economy, environmental protection, security civilization, energy conservation and social equivalent Yidu is huge.
Working principle: in use, one layer of 1 bottom of chimney outer cylinder, along barrel outside once assemble it is high by about 120
Centimetre hoisting frame 7, intermediate installation periphery ring 8 and the interior enclosure 9 of vertical bars 14 are promoted at two, is installed in the outside of interior enclosure 9
Inner template 10, assembling reinforcement in the space between inner template 10 and exterior sheathing 11, hangs between the reinforcing bar and periphery ring 8 of binding
Exterior sheathing 11 is sealed, top boom 19, lower boom 20 and brace 21 are passed through into fastener shaped by lapping, and upper berth in the inside of interior enclosure 9
Flitch and walkway board construct operating platform 5, installation oil pump, jack and hydraulic circuit, and jack uses six tons of ball-types very heavy
Top, hydraulic device use YHJ-36 type console, install cage and Tai Ling, cage handling concrete, reinforcing bar is transported in platform spirit, and inserts
Enter support rod, carry out test run, the casting concrete between inner template 10 and exterior sheathing 11 will by hydraulic system and jack
Inner template 10 and exterior sheathing 11 carry out sliding, and every layer concrete height control of climbing when pouring for the first time is at 30 centimetres hereinafter,
Even to pour in four times completely, for every layer concrete height difference less than ten centimetres, each interval time at one hour or so, enters mould coagulation for the first time
Soil started one to two stroke of initial rise at three to five hours (fixed depending on temperature), is no more than one hour every time later and mentions a stroke,
It prevents template from bonding, normal sliding, sliding formwork Control Measures for Concrete Slump is transferred to when guaranteeing concrete mould unloading strength in 0.2~0.4Mpa
Degree at five centimetres or so, upper layer concrete vibrating be inserted into lower-layer concrete depth without departing from 50 millimeters, it is sliding in stack shell
Because self-strength is still in growth, influenced by various factors such as wind load, equipment and materials weight, frictional force, the moment has certain
Shake, after each pourings layer promotes 60 centimetres, with plumb bob hang in it is primary, when deviation is beyond ten millimeters, carry out immediately low
Correction, avoids the occurrence of sharp turn phenomenon, assembling reinforcement in the space between inner template 10 and exterior sheathing 11, and vertical cutting length is
Four to six meters, when carrying out binding overlap joint, lap of splice 35d, same level nipple number less than 25%, the segmentation of circumferential muscle with
Convenient for across hoisting frame 7, the lap of splice is unified, the casting concrete between inner template 10 and exterior sheathing 11, and repetition climbs, binds
Reinforcing bar and casting concrete step top out until concreting is completed, and first remove hydraulic control when demoulding and set
It is standby, then periphery ring 8, exterior sheathing 11, interior enclosure 9 and inner template 10 are removed, foot hand then is hung inside and outside dismounting, then dismantling operation is flat
The lifting means such as platform 5, hoisting frame 7, jack.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
