The silo top construction method comprises the steps that a steel tube truss (2) is erected; a slip-form lifting system is prepared; the steel tube truss (2) is fixed through restraint of an upper enclosure (71) and a lower enclosure (72) of the slip-form lifting system; slip-form construction is conducted on the upper portion of a silo hopper, and the steel tube truss (2) is lifted to the construction position of a construction layer of a silo top in a supported mode; the steel tube truss (2) is separated from the slip-form lifting system, the slip-form lifting system is detached, the steel tube truss (2) is fixed, and therefore a supporting system of silo top construction is formed; the silo top is formed on the steel tube truss (2); after construction of the silo top is completed, the steel tube truss supporting system is detached. The silo top construction method has the advantages that construction is convenient and rapid, the work period can be obviously shortened, and the structure is simple; due to the fact that force transmission is definite, the work period can be shortened and the construction cost can be reduced; components are reusable, so that resources are saved.

Description

Top, a kind of silo storehouse construction method
Affiliated technical field
The invention belongs to structural engineering technical field, relate to top, a kind of silo storehouse construction method.
Background technology
Along with continuous increase and the raising to environmental protection requirement of coal demand, reserves are large, floor space is little, and the novel coal bunker that meets strategy of sustainable development requirement is widely applied at Coalmine Coal Preparation Plant and coal storage system.In coal bunker engineering construction, roof construction construction in storehouse is one of key link in work progress, and the design of storehouse roof construction support system and checking computations are particularly important to Cang Ding construction.The construction method of tradition support system is set up for full hall frame, and still along with the progress of construction technology, full hall frame formwork system is because its expense is high, speed is replaced by some novel Construction Supporting Systems slowly gradually.What first promote is that fastener type steel pipe trussed construction and center derrick combination form replace traditional full hall scaffold, derrick and steel pipe truss structures are connected as a single entity as the support system of deck construction, derrick is along with the lifting of slip form platform is progressively set up, drag-line is set on derrick height to be socketed support body, guarantee its stability, it is solid that derrick is set up ground, guarantees that derrick support body does not sink.After barrel slding form operation finishes, then carry out being connected of derrick and steel pipe truss system, this supporting form has well solved the construction of 18-22m Span-line Loading Dome layer, cost is relatively low, but increased center derrick, set up link, generally, promotional value is very high.On the basis of this support system, there is again shaped steel central frame radiation support platform, this structure is fastener type steel pipe truss and steel truss beam combination structure, mainly to utilize steel truss beam, as horizontal stiffness stiffening girder, steel pipe truss is retrained to reinforcement, the problem of the steel pipe truss structures supporting capacity deficiency causing because of the excessive generation excessive deformation of load in control use procedure, these two kinds of method constructions are convenient, safe and reliable, work efficiency is high, cost is low, but still break away from from silo bottom, does not set up the link of support.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of quick construction is provided, obvious reduction of erection time, simple structure, top, the silo storehouse construction method that power transmission is clear and definite.Method provided by the invention, has improved operating personnel's safety guarantee in construction, simultaneously the energy reduction of erection time, reduce construction cost, and member is reusable, has saved resource, meets structural-load-carrying capacity and the normal requirement of using.Technical scheme of the present invention is as follows:
Top, a silo storehouse construction method, comprises the following steps:
1) utilize steel pipe and fastener to set up into the space truss structure of the orthogonal spatial being comprised of a series of plane frame, be referred to as steel pipe truss (2), the size of steel pipe truss (2) is determined according to the internal diameter of the barrel of silo (10);
2) prepare sliding formwork Hoisting System, whole sliding formwork Hoisting System comprises hoisting frame (4), platform (5), template (6), upper enclosure (71), lower enclosure (72), the bar that climbs (8) and jack (9);
3) the upper enclosure (71) that sliding formwork Hoisting System is fixed on by right-angle coupler in the end that steel pipe truss (2) winds up is upper, and the end of lower edge is fixed in lower enclosure (72) by right-angle coupler;
4) above silo funnel, start slding form operation, steel pipe truss (2) is entrusted to top, storehouse construction layer construction location;
5) steel pipe truss (2) top oblique pull one is enclosed to wire rope (1) on silo, bottom is supported on silo by support (3) under a circle, form the support system of Cang Ding construction, method is: wire rope (1) one end is bundled on steel pipe truss (2) lower-chord panel point, the other end is bundled in silo and climbs on bar (8), lower support (3) one end is connected by on-right angle fastener with steel pipe truss (2) lower-chord panel point, and the other end is supported on silo.
6) bar (8) that will climb is stayed silo bulkhead the inside, removes sliding formwork Hoisting System;
7) in steel pipe truss (2) top, set up full framing, complete successively the construction of large ring beam (11), Exchanger with Inclined Taper Shell (12), little ring beam (13) and platform beam slab (14), form Cang Ding;
8) etc. Cang Ding construction complete after, then remove steel pipe truss support system, thereby Cang Ding construction is complete.
As preferred embodiment, the slding form operation method of step 4) is: around silo one circle, be covered with sliding formwork Hoisting System, concrete is watered in template grooving by the suitable for reading of template (6), in template grooving, undermost concrete reaches after certain intensity, template grooving relies on the lifting force of jack (9) by hoisting frame (4), edge is the barrel of placing of concrete (10), sliding one section of height makes progress, on one side that template grooving is upwards sliding to placing of concrete in template grooving so on one side, make the continuous demoulding of in type concrete, so continuous circulation is constructed to the position of silo Cang Ding construction, along with sliding formwork Hoisting System entrusts steel pipe truss (2) to top, storehouse construction layer construction location.
Beneficial effect of the present invention is:
1) top, silo of the present invention storehouse construction method, by setting up top, storehouse steel pipe truss system, on ground, set up steel pipe truss, the vertical support system transition that tradition is adopted is space horizontal supporting system, avoid setting up the process of support system in the air, improved operating personnel's safety guarantee in construction.
2) sliding to Cang Ding by slding form operation overall structure, shorten construction period.
3) temporary supporting system of setting up in work progress, employing be all steel tube component, member is simple, power transmission is clear and definite, has good functional performance.Because member is less, the Cang Ding complete dismounting of constructing is quite convenient, and recycling rate of waterused is high.
