The entire foundation is a concrete preformed member; and a middle foundation seat, a transitional connection foundation, a tail-end foundation and a fastener for the tail-end foundation are connected into a whole by self-fastening and by using pre-stressed steel strands. The foundation of the invention has the advantages of simple structure, high overall stability, high bearing capacity, high resistance to overturning and torsion, convenient, rapid, time-saving and labor-saving assembly, disassembly and transportation and long-term repeated use, eliminates the defects of fixed foundations for tower cranes, reduces the construction cost, saves the resources and accelerates the construction progress, thus achieving the purpose of environmental protection and bringing economic and social benefits at the same time.
Description
One, technical field
But the present invention relates to a kind of split-mounting type foundation for tower crane, belong to building machinery industry is installed.
Two, technical background
Along with the develop rapidly of building trade, the use of pillar crane is more and more, and with the increasing of annual several times, but the tower crane foundation that uses at present, great majority all adopt the cast-in-situ steel reinforced concrete basis.Every use once will be watered and smash once, remove once, cause resource, economy and artificial significant wastage; Building waste after dismounting or the explosion is contaminated environment again, is embedded in underground concrete foundation of not removing, and also will cause artificial hidden danger to the urban construction in future.Cast-in-place concrete foundation, fabrication cycle is long, a foundation for tower crane needs about about one month, if in the winter time then the time longer, not only influenced the construction speed of engineering but also reduced the turnover utilization rate of tower machine.
For overcoming the problems referred to above, but the present invention a kind of split-mounting type foundation for tower crane, adopt steel concrete, steel plate default, each basic assembly unit self-clinching connects, closely be formed by connecting with prestress wire, this foundation structure is simple, monolithic stability, anti-twisting is strong, be convenient to demolition, installation, transportation, can recycle for a long time, be i.e. environmental protection, economize on resources again, the saving of labor, save time, save land, be the cast-in-place substitute products of deciding foundation for tower crane of making firm by ramming of present building operations, have very high economic benefit and social benefit.
Three, summary of the invention
But a kind of split-mounting type foundation for tower crane of the present invention belongs to the building machinery industry.
Its objective is: but a kind of split-mounting type foundation for tower crane is provided, integral body is steel bar concrete and part steel plate, through punching block, smashing concrete is made, wherein form by 2-1 intermediate base seat, 3-1 transition connection basis, the terminal basis of 4-1, the terminal basic buckling piece of 6-1, the integral body on basis connects, be to disperse high-strength low relaxed prestress steel strand to be connected in one through self-clinching and employing, making whole basis is the full prestressing structure, the tower machine of corresponding different model on grade beam, pre-buried correspondingly foot bolt connects with the foundation for tower crane joint with stone bolt.As shown in Figure 1, integral body is 8 rib bodies, and the centre is the plum blossom body, its simple and beautiful structure, practicality.1, intermediate base seat Fig. 2, the centre is cross shape Ji Liang, leaves groove 2-2 in the middle of cross, is convenient to the easy to connect of tower machine connecting-rod bolts.Described from snapping body Fig. 2 B shape, by stretched under the last slow arc,, leave the 8-10 degree self-clinching arm of angle at the place, base angle, put into the reservation steel plate in the 2-4 position, strengthen collision lifetime, be convenient to Rapid Combination.At the 2-3 place, leave steel strand perforation place, this hole is a through hole.
2, transition connects foundation drawing 3: integral planar is shown in Fig. 3 B, for top is the semicircle angle body, in the 3-5 position is stone bolt, shown in Fig. 3 A, leave the 8-10 degree self-clinching steel plate arm of angle at Fig. 3 A3-2 place, base angle, during the weldable steel network framework and the welded corner joint of steel plate button together, 3-4 is a round end T font hook, the locking site when being used to sling.3-6 is the prestress wire perforation, and integral body is flat type, connects prestress wire with flat type ground tackle, and whole stressed more even, its drift angle form is beneficial to the alleviation of weight power.It is shown in the 3-7 that transition connects mutual pressure position, position, basis, and 4 transition connect bases as shown in Figure 1, withhold mutually, interconnect, and adherence ground is long-pending bigger, and fastness is stronger, and load-bearing will strengthen between the 10-15% than monomer.3-8 is the semicircle gusset, and purpose is used for the crowbar application point, prevents that cement from destroying, and also is beneficial to the insertion of crowbar, carries out driving fit as soon as possible, improves working efficiency.
3, a terminal basic seat integral planar is shown in Fig. 4 B, and the lower end is the semicircle angular shape, and width is bigger, adherence ground is extensive, and support force is strong, and 4-2 is the 8-10 degree self-clinching steel plate arm of angle, the 4-6 position is and withholds plate 6-2 junction that two ends closely interlock, and make whole terminal basis more firm.
4, each basis when assembly unit as shown in Figure 5, require tight and seam, the integral body on each basis connects through self-clinching and adopts and disperse high-strength low relaxed prestress prestress wire and ground tackle, be connected as a single entity by the cassette jack, there is the firm plate angle of 8-10 degree on each basis, and is closely knit for splicing, durable, snapping is rigorous, provides convenience.
5, terminal basic buckling piece as shown in Figure 6: 6-1 integral body is inverted ladder-shaped body, and 6-2 place and terminal basic 4-6 closely withhold, and increases the column foot own wt, strengthens anti-twisting, and the integral working of column foot is improved.Terminal buckling piece increases terminal basis and ground compressive stress, under the tilting moment effect, terminal basis is not occurred or occurs tensile stress less, has improved the anti-ability of inclining, thereby has guaranteed the resistance to overturning requirement, makes more steadily safety of tower machine.
6, Fig. 7 is a column foot plinth stone bolt drawing of site, and according to tower machine model difference, the stone bolt position is also different.Stone bolt gives and buries connection as shown in Figure 8: stone bolt 8-1 is a regular screw threads 45# steel, and 8-3 penetrates in the crotch of stone bolt bottom, and the lower margin bolt must not weld, and other all weld.
