Description
Technical field
The utility model relates to the prefabricated foundation for tower crane member of a kind of assemble type concrete.
Background technology
The prefabricated foundation for tower crane of existing assemble type concrete mainly is made up of a square central part, the square transition piece of four group leaders and four group leader's square end spares, four groups of transition pieces are arranged in four outsides of central part, four groups of extremity pieces are arranged in the outside of four groups of transition pieces, connect to form crossly between central part, transition piece, the extremity piece by steel hinge line, be respectively equipped with stone bolt box, anchor (bolt) hole, the stone bolt that cooperates with anchor (bolt) hole, stone bolt pad on transition piece, the extremity piece.Because this cross splicing structure makes the basis too little with the contact surface on ground, has greatly influenced basic stability, particularly the stability on power basis is carried in the base, lowland.
The utility model content
The utility model purpose is to design a kind of being convenient to and produces, installs, and the prefabricated assembling foundation for tower crane of power concrete member is carried in the base, lowland of improving base fixed.
The utility model comprises a central part of being made by steel concrete, four groups of transition pieces, four groups of extremity pieces, four groups of transition pieces are arranged in four outsides of central part, four groups of extremity pieces are arranged in the outside of four groups of transition pieces, connect to form cross between central part, transition piece, the extremity piece by steel hinge line, be respectively equipped with stone bolt box, anchor (bolt) hole, the stone bolt that cooperates with anchor (bolt) hole, stone bolt pad on transition piece, the extremity piece, transition piece is provided with two flanks, extremity piece also is provided with two flanks, and basic component also comprises eight ladder type pieces; Be provided with corresponding ladder type piece between the adjacent transition piece, the both sides of every ladder type piece are limited between two groups of adjacent transition pieces; Also be provided with corresponding ladder type piece between the adjacent extremity piece, the both sides of every ladder type piece are limited between two groups of adjacent extremity pieces; Two ladder type pieces between adjacent transition piece and extremity piece are connected with central part by steel hinge line.
After basic part assembling finished, between transition piece and the transition piece, set up two ladder type pieces between extremity piece and the extremity piece, in the corresponding increase of four direction, amounting to 17 stretch-draw basic part, ladder type piece fastening by steel strand by eight directions again was an integral body.Like this, not only increase the weight on basis self, also increased cube amount (being counterweight) of basic backfill, also increased basic floor space simultaneously.By calculating, the utility model basis is compared with former field fabrication basis, and the weight (deadweight+counterweight) on basis has increased by 20%～30%, and the base requirement of carrying power has reduced by 60%～80% over the ground.Strengthened basic stability greatly.By increasing the floor space on basis, with the basis over the ground the base requirement of carrying power be reduced to below the 5T/M2, to be suitable for more riverine, coastal and the relatively low area of power is carried in the base, ground.Another purpose that the utility model has been set up two ladder type piece designs is that the weight of ladder type piece monomer members is reduced, and is convenient to install, removes, transports.
In addition, between the utility model central part and the transition piece, be provided with the concavo-convex stepped end face that is connected that cooperatively interacts between transition piece and the extremity piece.
Above-mentioned technology has changed the plane contact between part and the part, compares with the prefabricated foundation for tower crane of other concrete, has increased contact area, has correspondingly just increased the horizontal anti-shearing force between them; On the contact end face, convex body, groove are arranged, come to reach up and down between reinforcement and the part anti-shearing force of horizontal direction.The anti-shearing structure of the prefabricated foundation for tower crane of its alternative other concrete, and basic part between anti-displacement formation, can reduce production costs.Stairstepping is made at the two ends of transition piece, is more conducive to and being located by connecting of central part, transition piece, and has made things convenient for installation.
In order to guarantee the stability on basis, the anti-shearing force between reinforcement and the part is provided with groove and the convex body that cooperatively interacts between the stepped end face of transition piece of the present utility model and the stepped end face of central part.
In like manner, be provided with groove and the convex body that cooperatively interacts between the stepped end face of the stepped end face of transition piece and extremity piece; Be respectively equipped with groove and the convex body that cooperatively interacts on the ladder type piece of adjacent transition piece and the central part opposing end faces; Two ladder type piece opposing end faces between adjacent transition piece and extremity piece are respectively equipped with groove and the convex body that cooperatively interacts.
Fixedly install hollow section and hard tube connector in the extremity piece of the present utility model, the outer end of hard tube connector splits the outer end at extremity piece, the mutual socket of the inner of hard tube connector and hollow section, steel hinge line is set in hollow section and the hard tube connector, the outer end of steel hinge line is positioned at the outer end of hard tube connector, and is fixed on the outside of extremity piece by ground tackle.
By using prestressing technique, install on the basis, when removing, can select arbitrary extremity piece to carry out stretch-draw, move back anchor according to the situation in place.Solved other the prefabricated foundation for tower crane of concrete, when the steel strand of stretch-draw end because impaired destruction and can not move back anchor, the awkward situation that the basis can't be removed.The prefabricated foundation for tower crane of other concrete is that an end is fixed with the extruding rivet clasp; Tensioned at one end, move back anchor.Install, remove more convenient by comparison.
In order to strengthen the compressive strength of extremity piece, increase the compression area of extremity piece, the utility model also is provided with heavy pressing plate between ground tackle and extremity piece.
In addition, the stone bolt of the utility model transition piece is threaded in the stone bolt pad, offers at least two horizontal pin-and-holes on stone bolt, cooperates latch on the stone bolt of the below of stone bolt pad.
The stone bolt of extremity piece is threaded in the stone bolt pad, offers at least two horizontal pin-and-holes on stone bolt, cooperates latch on the stone bolt of the below of stone bolt pad.
Adjusting for the ease of the stone bolt height, can be according to different tower machines, on the stone bolt of transition piece, extremity piece, select pin-and-hole position correspondingly, regulate the height of stone bolt simultaneously according to the cross deck-molding of tower machine, realize the effect of " base " multitower, removed the trouble that stone bolt will be changed in the prefabricated basis of other concrete from.
