Abstract
The present invention relates to a construction method for constructing a concrete cylinder body without a headframe or a scaffold. The present invention is characterized in that a lift-type door frame is attached to the cylinder wall of the cylinder body and is provided with a lifting device which is matched with the cylinder body to increase height; the door frame can be lifted along the cylinder wall and has the function of a vertical headframe; an operating platform and a template system are suspended on the cylinder wall to follow the pouring operation and the solidifying operation of the concrete of each circle of the cylinder body to rotate from bottom to top to be lifted to perform the function of the scaffold; the coordinate centering method is adopted to control the construction center of the cylinder body not to offset, etc. The present invention is suitable for the construction of the concrete cylinder body of any height, and the headframe and the scaffold are saved. Thereby, steel materials are saved, and the economic benefit is obvious.
Description
The invention belongs to building field, relate to the concrete barrel building method, be applicable to the building of the concrete barrel of any height, the building as chimney, high pressure stringing tower, TV transmission tower etc. does not need to run derrick and scaffold.
Prior art concrete barrel construction method generally is to run derrick, erecting under the scaffold condition, adopting the sliding formwork method, carry modulus method, job practicess such as turnover panel method.
A kind of building concrete chimney stack method SU1441038 is disclosed as the Soviet Union, establishing central authorities in its stack shell runs derrick, and pursue joint and set up, it is long to take man-hour, though running derrick, perpendicular central authorities lack than the steel quantity consumption that runs derrick outward, but also need considerable steel material, and steel using amount increases and increases along with the concrete barrel design height.Adopt the interior working platform of mechanical lifting mechanism, play perpendicular interior scaffold effect, but cylinder body outer wall does not have working platform, the constructor props up template, when tying up reinforcing bar, operates extremely inconvenience, uneasy again congruent weak point outside cylindrical shell.
And for example France discloses a kind of reinforcement concrete chimney construction method 2587393, and it adopts and carries modulus method, and its vertical transport adopts hydraulic test to promote, and costs an arm and a leg.
At present still disputable to the construction quality of slip-form construction method, be prone to scalelike mark as the concrete barrel inwall, outer wall causes transverse crack easily or S distortion etc. occurs, influences the concrete barrel quality.
Comprehensively above-mentioned, there is main weak point in prior art:
1. generally adopt and run derrick, erect scaffold, need to consume great deal of steel, one-time investment is big;
2. the employing hydraulic test that has promotes, and costs an arm and a leg;
3. the construction quality of slip-form construction method remains in some problems etc.
Purpose of the present invention, for overcoming present technical deficiency part, a kind of job practices of building concrete cylindrical shell is provided, i.e. employing is adhered to the lift-type door frame and is replaced running derrick, and adopts the suspension type operating platform to replace perpendicular scaffold, employing turnover panel job practices etc., thereby saved the great deal of steel that runs derrick and consumed, saved the expensive investments of hydraulic lifting device, and construction safety has been arranged, advantage such as quality is good.
Technical scheme of the present invention: employing is adhered to the lift-type door frame and is replaced running derrick; Adopt place's two circle suspension type operating platforms replacement scaffolds (comprising suspension type tripod and typing frame plate) in the cylindrical shell; The job practices of concrete barrels such as the turnover panel construction method of employing unit combination template system and employing centering platform coordinate centralising device.Adhere to the lift-type door frame attached on the barrel of building the concrete barrel that solidifies, door frame uses lifting appliance can cooperate cylindrical shell to build height, promotes by joint; Template system along with the concrete pouring of the every circle of cylindrical shell, solidify, from bottom to top have enough to meet the need turnover panel method construction; Adopt coordinate centering method to control and build cylindrical shell center non-migration.Work progress is: pouring → lifting → pouring again → promote again, until being built into the barrel designs height.
The major advantage of the building method of concrete barrel of the present invention:
1, building method of the present invention is applicable to the building of the concrete barrel of any height, as buildings such as chimney, high pressure stringing tower, TV transmission tower, do not need to run derrick, do not need scaffold, as adhere to the lift-type door frame, use lifting appliance, can cooperate cylindrical shell to build height, can promote by joint, replaced running derrick, played the effect that runs derrick.
2, one-time investment is few, saves steel, and economic benefit is remarkable especially.Make one and adhere to the lift-type door frame, only need about 3 tons of steel, add template etc. again and need 4.2 ten thousand yuan altogether, more than run derrick or sliding formwork instrument and pole-climbing steel quantity consumption few.Just need 5.3 ten thousand yuan and erect 150 meters high derricks, adding steel sliding formwork, hydraulic test etc. again needs 26.3 ten thousand yuan altogether, 4.3 times of saving funds, and chimney of electric plant uses building method of the present invention up to 270 meters at present, and saving steel and fund are more remarkable.
3, job practices tube list of the present invention, easily grasp, the artificial easily control of construction quality.Adopt coordinate centering method as the cylindrical shell center, control and guarantee cylindrical shell building center non-migration.Template system and for example, adopt the unit template, artificial available adjustment template is adjusted the width and the gradient, mesh tightly not spillage between template, the seam crossing concrete surface is smooth etc. between upper and lower two-layer template, manually according to after the concrete setting by the joint reverse mould, can not look like slip-form construction method, take place easily that S reverses, scalelike mark etc. influences construction quality.
4, construction safety is reliable, and mechanical accident is few, and safety factor is big.As adopting inside and outside two-layer lapful safety net, the inside and outside wall of cylindrical shell is provided with two operating platforms, railing, handrail etc.Also adopt double joint wire rope, hoisting rope, its safety factor is multiple safety precautions such as 14 times.
5, facility of the present invention is as adhering to the lifting door frame, compact conformation, and it is little to take the construction plant, is specially adapted to the narrow and small structure engineering construction in place.
6, construction techniques of the present invention is more simple to operate than construction methods such as sliding formworks, and general skilled worker just can grasp, and the saving of labor, saves time, so this method unit in charge of construction is willing to adopt, broad prospect for its application is arranged.
