Abstract
The utility model discloses a kind of prefabricated filled-type truncated cone type shell foundation, there is the rigid foamed carcass of truncated cone-shaped and hollow round table shape housing, the rigid foamed carcass of truncated cone-shaped fills full hollow round table shape enclosure interior, hollow round table shape housing is steel plate material or steel concrete material, prefabricated filled-type truncated cone type shell foundation of the present utility model and manufacture method thereof make the truncated cone type basis of building and structure realize factorial praluction by particular technology process, thus shorten the time of foundation construction, and reach the convenient transport of light-weighted requirement by special form of structure, lifting, simultaneously, obviously can save construction costs, and the cost that can reduce social need-oriented significantly and soil is reclaimed.
Description
Technical field
The utility model belongs to concrete structure construction field, is specifically related to a kind of shell foundation.
Background technology
Shell foundation is a kind of hollow thin-wall basis.Because thin shell structures has the feature of " Space-Work ", available less material, thinner thickness makes structure have larger Rigidity and strength, can bear larger load.It is compared with usual bulk basis, has and saves material, advantage such as reduction cost and Accelerating The Construction speed etc.Adopt space thin walled construction formula to replace the mass foundation continued to use, make structure transfer the main state by membrane internal force to from the state mainly by curved internal force, this just can save material in a large number.Engineering practice proves, adopts shell foundation to replace solid bulk basis can save concrete and is about 30%-50%, saves reinforcing bar and is about 10%-20%, and for large-scale structure and autonomous device basis, its economic indicator is just lower.Due to the minimizing of earth volume and amount of concrete, labour and engineering time be also all corresponding to be reduced to some extent.
Facts have proved, underground construction adopts thin shell structures to have condition advantageously than superstructure, and such as can make full use of native tire is mould, thus solves the template problem of shell.Past, often by the native tire dug up, form a kind of " sandwich " structure, co-operation with housing shell is inner now, this stability for basis, resist horizontal force, slip and opposing sedimentation performance all beneficial.And, on soft foundation shell foundation sedimentation and tilt all very little, some building that must drive piles in past, avoids piling after have employed shell foundation, reduces cost, accelerate construction speed.
Because shell foundation is large compared with plane with the contact surface of soil, the factor such as co-operation of the better and native tire of shell surface elastic makes shell foundation also have the performance of vibration damping.
Shell foundation requires higher construction quality, and key is formation and the concreting of native tire.Soil tire digs and carry out secondary unwrapping wire to shell top mark height, and with manually shelling soil from level to level, native tire should retain not by the undisturbed soil of disturbance.Concrete compactness direct relation the anti-crack ability of shell, therefore, match ratio, water/binder ratio, the slump, to vibrate and maintenance all should conscientiously be carried out.
Although the advantage of shell foundation is many, promote the use of for many years slowly, its reason is as follows:
One, the shaping of tire of shell foundation soil by manually completing, must be unfavorable for mechanized construction;
Two, compared with mass foundation, design is complicated, and construction also bothers, and therefore uses face large not enough.First problem of perception should be solved.Construction work infrastructure investment accounts for very large proportion, affects whole construction costs.The shell foundation of truncated cone shape and combination form thereof, is used for general industry and civic building base for post and barrel-shaped structure (as chimney, water tower, feed bin, medium and small blast furnace etc.) basic.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of prefabricated filled-type truncated cone type shell foundation, prefabricated filled-type truncated cone type shell foundation of the present utility model makes the truncated cone type of building and structure basis realize factorial praluction thus shorten the time of foundation construction by particular technology process, and reach the convenient transport of light-weighted requirement, lifting by special form of structure, simultaneously, obviously can save construction costs, and the cost that can reduce social need-oriented significantly and soil is reclaimed.
The utility model in order to the technical scheme solving its technical problem and adopt is:
A kind of prefabricated filled-type truncated cone type shell foundation, has the rigid foamed carcass of truncated cone-shaped and hollow round table shape housing, and the rigid foamed carcass of described truncated cone-shaped fills full described hollow round table shape enclosure interior.
Say further, described hollow round table shape housing can be steel plate material hollow round table shape housing.
Say further, described hollow round table shape housing is steel concrete material hollow round table shape housing.When there being larger requirement to bearing capacity, described steel concrete material hollow round table shape hull outside has and is fixed with compressor wire and cement sand bed.
Say further, the rigid foamed carcass of described truncated cone-shaped is truncated cone-shaped RPUF carcass.
The beneficial effects of the utility model are: the utility model cast-in-placely changes into truncated cone type shell foundation prefabricated by traditional, while making truncated cone type shell foundation be applicable to the basis of small-sized basis and structure, overcomes the problem that design is complicated; By the change of base form, greatly alleviate basis weight than mass foundation, simplify the step of foundation construction, lower construction costs; Circular platform type RPUF replaces native tire as shell inside stuffing, overcomes the drawback of original soil tire construction forming difficulty; The middle-size and small-size basic regularization of a lot of infrastructure is made by factorial praluction, as the basis of enclosure wall, the basis of direction board, the basis of light pole, the basis etc. of bus platform, not only accelerating construction progress, and cost-saving, and the cost that can reduce social need-oriented significantly and soil is reclaimed; Prefabricated filled-type truncated cone type shell foundation of the present utility model simplifies the program of foundation construction, accelerate the speed of foundation construction, for precast assembly building provides brand-new thinking, precast assembly is built and finds breach in foundation, full precast assembly is built becomes possibility.
