Abstract
The invention discloses a socket-joint type prefabricated part of a ring wall foundation. The prefabricated part is in the shape of an arc-shaped part formed after the ring wall foundation is equally divided along the perimeter, and two ends of the prefabricated part are arranged to be grooves and tongues. The invention further discloses the ring wall foundation which is composed of multiple prefabricated parts. The arc-shaped reinforced concrete prefabricated part with a rectangular section is simple in structure, the ring wall foundation is easy to mount during construction, and additional arrangement of steel bars and set-up of a formwork are not required, so that curing time is reduced, and construction is quickened greatly; meanwhile, the prefabricated part is easy for industrial standard part production.
Description
Technical field
The present invention relates to a kind of geotechnical engineering basis, particularly a kind of steel tank ringwall basis prefabricated units.
Background technology
Steel tank is a kind of use special equipment very widely, and the big or small steel tank that China builds every year and transforms is countless.Base of steel tank generally has bank protection formula and ringwall (beam) formula, and ring wall foundation is owing to adjusting tank body foundation uneven settlement successful, and takes up an area less, is suitable for all kinds of soft foundations and is widely adopted.Ring wall foundation can be divided into Cast-in-situs type and prefabricated assembled again, but at the bottom of prefabricated assembled template utilization rate, during construction assembling, easily produce alignment error, when particularly prefabricated component connects, adopt ater-casting (sleeper form) connected mode, need to set up in addition template and reinforcing bar is set, construction bothers, curing time is long, thereby in engineering, substantially adopts Cast-in-situs type ringwall basis at present.But it is that Cast-in-situs type ringwall basis is incomparable that concrete adopts the prefabricated assembled feature that is easy to the production of industrialized standard part, if take a kind of rationally prefabricated component connection efficiently make, overcome ringwall basis prefabricated component and connect intrinsic defect, the basis of this form is to have very much application value.A key in prefabricated ringwall basic engineering is: it is that a kind of full section is continuous, the tension of take is main concrete component, in the process connecting, needs the member resistance to tension that guarantees link position place to be not less than prefabricated units itself.
Those skilled in the art is devoted to study a kind of new ringwall basis, to solve the technical problem on prefabricated assembled ringwall basis in prior art.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome in prior art at the bottom of prefabricated assembled ringwall foundation construction template utilization rate, during construction assembling, easily produce alignment error, reinforcement construction trouble is set in ater-casting, the problems such as the concrete curing time is long, provide a kind of ringwall basis spigot-and-socket prefabricated units and ringwall basis.
The present invention solves above-mentioned technical problem by following technical proposals:
Basis spigot-and-socket prefabricated units, its feature is, described prefabricated units be shaped as ringwall basis along the arc component forming after girth decile, described prefabricated units two ends are set to tongue and groove.
Preferably, the inside that described prefabricated units are positioned at tongue and groove place is provided with steel frame.
Preferably, the arc length of described prefabricated units is not less than 1.5 meters.
Preferably, the arc length of described prefabricated units is 1.5～2 meters.
Preferably, described prefabricated units are made by steel concrete.
Preferably, described prefabricated units cross section is rectangle.
A kind of ringwall basis, its feature is, described ringwall basis is connected to form by tongue and groove socket joint mode by a plurality of aforesaid prefabricated units.
Preferably, between the tongue and groove of adjacent two prefabricated units, leave gap, gap is filled with and is filled out with contraction-free grouting concrete.
In the present invention, above-mentioned optimum condition can be combined on the basis that meets this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: steel concrete rectangle section arc prefabricated units of the present invention are simple in structure, simple installation during ringwall foundation construction, do not need to arrange in addition reinforcing bar and set up template, thereby minimizing curing time, greatly improved speed of application, meanwhile, prefabricated units are easy to realize the production of batch production standard component.

The specific embodiment
Embodiments of the invention describe with reference to the accompanying drawings.In Figure of description, element or the device with similar structures or function will represent with identical component symbol.Accompanying drawing is each embodiment of the present invention for convenience of explanation just, is not to carry out to the present invention the explanation of exhaustive, neither limit scope of the present invention.
Fig. 1 has disclosed the schematic top plan view on Large Steel storage tank ringwall basis under one embodiment of the invention.In this embodiment, ringwall basis is by 16 equal and opposite in directions, and the single prefabricated units 1 that shape is identical form.Those skilled in the art can understand, the diameter on ringwall basis is determined by supported steel tank diameter.In general, the diameter on ringwall basis is larger, need to be more along the quantity of girth decile.The monolithic weight of aliquot-sized after with each member decile is easy to construction hoisting and is as the criterion, and conventionally can be 1.5 ~ 2.0 meters of arc length.These single prefabricated units, can carry out standard component Prefabrication in factory very easily, and structure manufacture quality can be guaranteed, and during on-the-spot installation, directly lift erection, form steel tank ringwall basis.
Fig. 2 is the schematic perspective view of single prefabricated units.These prefabricated units consist of monolithic steel concrete, and member intermediate body member 11 is arcuation, and member cross section is rectangle, and tongue and groove shape is made at member two ends, and tongue and groove comprises protuberance 12 and recess 13.
Fig. 3 and Fig. 4 show the schematic diagram that single prefabricated units are combined into ringwall basis.In this embodiment, two prefabricated units vertically insert by tongue and groove, protuberance 12 and recess 13 between prefabricated units 1 agree with each other, and the seam crossing after two prefabricated units connect guarantees to leave the gap of 20-30mm, forms the bayonet joint of prefabricated component.After connection is in place, with temporary formwork 2, seal gap, place, the gap perfusion slurry 3 between tongue and groove, this slurry 3 can be contraction-free grouting concrete, also can be the pea gravel concreten with microdilatancy, gap be filled out slurry by filling and is sealed, thereby guarantees closely to connect between member.
Fig. 5 and Fig. 6 show the steel frame position of single prefabricated units inside.In general, single prefabricated units are not less than the resistance to tension of prefabricated units body 11 at the resistance to tension at recess 13 and protuberance 12 places, therefore configure in prefabricated units beyond plain bars, steel frame 13 are also set separately.The structure of steel frame is determined by full section ringwall stretching resistance, can make with angle steel, also can make with other suitable material.While preventing like this, largely ringwall basis under tension, cause member fracture.
Although described above the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection scope of the present invention.
