Greatly, with the obvious advantage, development prospect is wide.
Existing building adds the elevator basis of elevator engineering mainly using cast-in-situ steel reinforced concrete basis, such basis is deposited
In long construction period, complex procedures, pollute the defects of low environment, recycling rate of waterused and poor mechanical property.In addition existing building increases
If when elevator, since operating space is small, construction is inconvenient, so that assembling type base draws attention.
Certain air base radar system signal tower foundation in Greenland has used a kind of novel fabricated basis, due to lattice
Mound Orchid Island is close to the arctic, and ground belongs to permanent frozen soil, and long-term low temperature, wind speed is big, and the only trimestral hot weather construction phase, this gives
Situ wet operation brings very big technology and logistical challenge, and seriously consumes the limited construction time.The novel fabricated
The prefabricated components on basis are produced in USA, and only there are two types of forms for prefabricated components, transport directly to Greenland and installed, are passed through
Scene splicing, post-tensioning anchoring, then the form being in the milk form entirety, and the above problem is avoided and solved well.
Chinese Patent Application No.：201610514412.6 disclosing a kind of Manual assembled type basis.The Manual assembled type base
Plinth, including base unit block, the base unit block is square, and the upper surface edge of base unit block is provided with positioning
Protrusion, the lower surface of base unit block are provided with the location dimples matched with the positioning protrusion of another base unit block, fixed
Position high spot is provided with location hole through base unit block, and for positioning hole through there is locating rod, locating rod upper end is provided with locking
Nut.The invention, which has, to be able to carry out disassembly, is conveniently replaceable column foot position, the utilization rate for effectively improving column foot etc. beneficial to effect
Fruit, but have simultaneously and height is required to each component installation accuracy, working procedure is cumbersome, and basic Punching Shear and anti-horizontal sliding are stablized
Property is not easy the defects of guaranteeing.
In conclusion assembling type base is with having standardized designs, the factorial production, assembled in situization is constructed, wet work
The features such as industry amount is few and environmental pollution is small.Although having been taken both at home and abroad for the research and development of the assembling type base of power transmission tower and communication base station
Certain achievement is obtained, but is directed to steel construction elevator assembling type base, corresponding developmental achievement is seldom.Therefore, we should borrow
Research and development experience, summary have prefabrication and assembly construction technology to mirror both at home and abroad, and research and development are suitable for the assembling type base of steel construction elevator, to shorten
Construction period reduces the influence to ambient enviroment, and large-scale popularization application.
Summary of the invention

Solidifying soil prefabricated section, convex concrete precast block, prestress wire, anchorage, steel column, foundation bolt, gasket, nut and brick wall etc.
It constitutes.Assembled Raft Foundation Design principle is that vertical direction is snapped connection using the tongue and groove between block, and horizontal direction passes through
Prestress wire carries out tensioning connection, to improve the overall stability of structure.
Further embodiment is：Steel column is quadrate steel pipe column, connect one end with basis and is welded with end plate, is reserved with spiral shell on end plate
Keyhole.
Further embodiment is：Spill concrete precast block and convex concrete precast block be all made of specific mold at
Type all has the preformed hole for meeting design requirement, and Forming Quality is high, good mechanical performance, is convenient for assembled in situ.
Further embodiment is：Pass through prestress wire between spill concrete precast block and convex concrete precast block
Tensioning connection is carried out, prestress wire both ends are anchored using specific anchorage, eventually form assembled raft foundation.
Further embodiment is：Anchorage is made of steel sleeve and intermediate plate, can well to prestress wire both ends into
Row anchoring.
Further embodiment is：Foundation bolt passes through the bolt hole of assembled raft foundation, then passes through the end plate of steel column,
Steel column and assembled raft foundation are connected to become entirety.
Further embodiment is：After steel column connect with assembled raft foundation it is integral after, steel column and steel in every side
Intercolumniation builds the brick wall of certain altitude, prevents surrounding soil from entering elevator foundation pit, guarantees that elevator just at operation, ultimately forms applicable
In the assembled raft foundation structural system of steel construction elevator.
It is an advantage of the invention that：The structural system on-site wet operation amount is few, and environmental pollution is small, short construction period；Concrete
Prefabricated section uses standardized designs, the factorial production, light weight, formed precision height；By convenient for assembly between concrete precast block
And disassembly.Its active response country widelys popularize the call of assembled architecture, highly meets the production method of green construction.
