Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of prefabricated assembled sinking basis of additional building elevator, including enclosure wall 1, bottom plate 2
With bed course 3.The bed course 3 is using plain mortar cast in situs in foundation pit；The bottom plate 2 is tabular, is put into bottom plate and passes through
Sit slurry mode to be placed on the bed course element mortar of the ot-yet-hardened of bed course 3, make bottom plate close with layer contacts, so as to the bottom of by
Various loads on plate are evenly transferred on the ground of periphery.The enclosure wall 1 is rectangular box, is consolidated by reinforced concrete anchorage style
The upper surface of the bottom plate is scheduled on, is tamped with soil layer 4 outside it.
As shown in Figure 1, shown in Figure 5, multiple hollow plastic ball 2-4 are filled in the inside of bottom plate 2, and each spheroid is all that top surface is plane
It is hemispherical, concrete amount can be reduced on the premise of proof strength；As shown in Fig. 1, Fig. 3, Fig. 4, the upper surface of bottom plate 2
It is prefabricated with and is engaged with the shapes and sizes of enclosure wall 1, is easy to be embedded in the rectangle concave station 2-9 of enclosure wall 1, concave station 2-9 using
In elevator hoistways can be born it is each be directly delivered to horizontal wind excitation, dynamic load by enclosure wall on bottom plate, reduce or eliminate
The horizontal loading that connection enclosure wall 1 is born with four muscle steel bar column 2-1, the vertical reinforcing bar 2-3 of bottom plate 2, improves elevator hoistways structure
The degree safe to use of system；The pre-buried steel plate 2-2 for being used to install various elevator accessories in concave station 2-9 upper surfaces；Beside concave station 2-9
Provided with the suspension ring 2-5 for lifting.
As shown in figure 4, bottom plate 2 is decomposed into two and half bottom plates according to elevator size is uniform in size, and use horizontal post-cast strip 5
Connection；As shown in Fig. 2 the enclosure wall 1 is decomposed into the half-enclosure of symmetrical two pieces of flute profiles, connected using two vertical post-cast strips 5
Connect.After enclosure wall 1, the Symmetric Decomposition of bottom plate 2, reduce volume, the weight of each component, be easy to it is prefabricated, suitable for common vehicle transport
It is defeated, and be easy in lifting construction in small space around existing building.As shown in Fig. 2 half-enclosure is across floor level post-cast strip
5, avoid horizontal post-cast strip from being appeared in vertical post-cast strip in same vertical plane and form the weakness zone of insertion, ensure this
Prefabricated assembled basic bulk strength.
As shown in Figure 1 and Figure 2, the top surface corner of enclosure wall 1 is provided with pre-embedded bolt 1-1, the pre-buried steel of installation elevator hoistways framework
The plate 1-2 and suspension ring 2-5 for lifting.
As shown in figure 8, two and half bottom plate interfaces and two pieces of half-enclosure interfaces are inner opening groove shape, can make
The gap on upstream face that component contacts with soil minimize, and reduces permeable probability, and can be stayed in groove for connection reinforcing bar
Go out enough construction spaces；The side reinforcing bar 2-8 and land side reinforcing bar 2- that meets water is set respectively from lower to upper in the half bottom plate groove
6；Ecto-entad sets the side reinforcing bar 2-8 and land side reinforcing bar 2-6 that meets water respectively in the half-enclosure groove；The side reinforcing bar that meets water
2-8 is connected with each other in a manner of overlapping chain intermittent weld, and the land side reinforcing bar 2-6 passes through plasm pouring in plane sleeve 5-1 or cold-extruded gland
Cylinder or solder design；The side reinforcing bar 2-8 that meets water is overlapped after the inside bending in end to reach length as defined in specification, then simultaneously
Row are welded as a whole, and ensure the bonding strength of reinforcing bar；Described meet water is provided with sealing between side reinforcing bar 2-8 and land side reinforcing bar 2-6
Steel plate 2-7, can blocking concrete seam, and be closely connected with basic blocks 1, post-cast strip concrete, prevent post-cast strip 4 from outside to inside
Infiltration.
As shown in figure 9, the four muscle steel bar column 2-1 includes four uniform reinforcing bars, more stirrups longitudinally are provided with along it, will
Its colligation into the transition of platform shape and lower small variable cross-section cylindricality upper greatly, wherein, heavy in section section, platform shape section are embedded to be cast in the bottom plate
It is interior；The steel bar column of small cross sections and more vertical reinforcing bar 2-3 expose concave station 2-9 upper surfaces in four muscle steel bar column 2-1, and insert
It is embedded in the bellows 1-3 in the bottom surface of enclosure wall 1, is reinforced outside bellows with tie hoop 1-4, such node can be strengthened
Shear resistance and bonding strength；High-strength mortar 5-2 is filled inside bellows 1-3, forms vertical connecting node.What bottom plate was reserved
Steel bar column 2-1 is handled through above-mentioned variable cross-section, directly can be connected with the less wall of thickness by grouting way, is avoided using company
Connect the grout sleeve of reinforcing bar, cold extrusion sleeve need to reserve it is longer after pour section, protective layer need to be thickened increase thickness of wall body etc.
The puzzlement of problem.As shown in Fig. 4, Fig. 6, Fig. 7, because size is limited near groove, not pre-buried bellows, then in the bottom plate 2
Positioned at vertical post-cast strip 5, nearby pre-buried vertical reinforcement, half reserved grout sleeve 1-5 of insertion enclosure wall 1 bottom are connected by being in the milk.
As shown in fig. 7, the inner side and outer side of the enclosure wall 1 and the connecting sewing of bottom plate 2 is blocked with waterproof material 6, this is prevented
Seam crossing seeps water.
As shown in figure 8, it is provided with longitudinal reinforcement 5-3 in the post-cast strip 5, it is ensured that it has enough bulk strengths.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
