Description

The concrete foundation structure of tower machine
Technical field
The utility model relates to field of civil engineering, specifically is a kind of pillar crane concrete foundation structure of (being called for short the tower machine).
Background technology
Along with the fast development of urban construction and the exploitation of the large-scale underground space of highrise building, also more and more widely as the application of the pillar crane of one of main construction machinery (being called for short the tower machine) in engineering construction.The hoisting moment of the tower machine of different model is different; And the load that the concrete foundation structural requirement that the bigger tower machine of hoisting moment is installed carries, moment of torsion etc. are all bigger, and the load of the concrete foundation structural requirement carrying of the less tower machine of hoisting moment, moment of torsion etc. are smaller naturally.So the middle-size and small-size tower machine that generally hoisting moment is less than or equal to 80Tm in the industry is installed on the small-size concrete foundation structure, and the big-and-middle-sized tower machine of hoisting moment greater than 80Tm is installed on the large-sized concrete foundation structure.
In practice of construction, the work progress later stage begins up construction building owner body structure from basement bottom board during, need the steel pipe column or the steel column of hoisting large-size, must adopt the bigger big-and-middle-sized tower machine of hoisting moment this moment; And before this, when just construction foundation pit supporting and protection structure reaches earth excavation, only adopt the less middle-size and small-size tower machine of hoisting moment just can satisfy the construction needs.Must adopt big-and-middle-sized tower machine when considering construction in later period, be the large-sized concrete foundation structure that is used to install big tower machine so the workman pours into a mould on-site, and large-sized concrete foundation structure can only be installed big-and-middle-sized tower machine and the trourelle machine can not be installed; Like this; In construction in earlier stage, when just construction foundation pit supporting and protection structure reached earth excavation, this stage often will continue about 1 year; Though can adopt middle-size and small-size tower machine fully in this stage; But because the large-sized concrete foundation structure of installing on the building site can only be installed big tower machine and the trourelle machine can't be installed, this just causes hoisting moment waste seriously more than needed, and lease uses big tower machine expense higher.
Summary of the invention
The technical problem that the utility model will solve is that a kind of concrete foundation structure that the tower machine of middle-size and small-size tower machine and big-and-middle-sized tower machine can successively be installed is provided.
The technical solution of the utility model is, a kind of concrete foundation structure with tower machine of following structure is provided, and it comprises reinforced concrete footing; Be embedded with four vertical crab-bolts in the concrete bed, the end face of reinforced concrete footing is stretched out on the top of crab-bolt, and crab-bolt upper end is provided with and is used for the device that is connected with big-and-middle-sized tower machine; Four crab-bolts are two parallel row and arrange; Whenever classify two crab-bolts as, four crab-bolts are four jiaos of distributions, and it also comprises the base section steelframe that is positioned at four crab-bolts centres; The bottom of base section steelframe is anchored in the reinforced concrete footing, and the top of base section steelframe is provided with and is used for the device that is connected with middle-size and small-size tower machine.
After adopting above structure, the concrete foundation structure of the utility model tower machine compared with prior art has the following advantages:
Because the concrete foundation structure of this tower machine has had four crab-bolts that are used for being connected with big-and-middle-sized tower machine concurrently and has been used for and middle-size and small-size tower machine connection basis joint steelframe; So in earlier stage in construction; Just about 1 year of construction foundation pit supporting and protection structure and following earth excavation, can middle-size and small-size tower machine be fixed on the base section steelframe, in the construction later stage; During beginning up construction building owner body structure from basement bottom board; The middle-size and small-size tower machine of can dismantling, and cut away the base section steelframe that exposes the concrete bed end face, and utilize crab-bolt to install and fix big-and-middle-sized tower machine; So the seriously rich phenomenon of wasting of the gravitational moment that adopts big-and-middle-sized tower machine to cause in the time of effectively avoiding in earlier stage constructing is saved in earlier stage the cost of leasing, using big-and-middle-sized tower machine significantly.
As improvement, each crab-bolt comprises a vertical angle steel and a base plate, and the lower end of angle steel and base plate welding are welded with floor between angle steel and the base plate, such crab-bolt structure, firm, stable and saving material.
As improving, every row crab-bolt also comprises one group of two parallel dowel again, and two base plate spot welding of two crab-bolts of every dowel and these row are fixed, and like this, can strengthen the connection between two crab-bolts of same row, makes it more firm.
As also improving; Be welded with two first split heads muscle on lower floor's steel mesh reinforcement of reinforced concrete footing; The end face of each first split heads muscle and one group of dowel spot welding are fixed; Like this, can crab-bolt and lower floor's steel mesh reinforcement be fixed through the dowel and the first split heads muscle, crab-bolt is impacted displacement by concrete when preventing to water the concrete of smashing reinforced concrete footing.
As improving again; The two orthogonal risers upper end of the angle steel of every crab-bolt is provided with the junction plate of a band through hole, and also is provided with the bolt via hole corresponding with the junction plate through hole on the column of big-and-middle-sized tower machine lower end, and the bolt of the bolt via hole through passing junction plate through hole and column just can be fixed up the column and the crab-bolt of big-and-middle-sized tower machine lower end; And; Junction plate on the crab-bolt is orthogonal two, like this, and with every root post of big-and-middle-sized tower machine and every crab-bolt fixedly the time; Two bolts are vertical each other, from level to X, Y axle both direction column and angle steel are fixed.
As further improvement, the base plate of every crab-bolt is provided with the breach of ccontaining base section steelframe near the angle of base section steelframe, and like this, the base section steelframe in the middle of avoiding interferes with each other with the base plate of four crab-bolts all around.
As further improving, the base section steelframe is by four root posts and the cuboid framework that two-layer level is formed to square frame at least again, and such sound construction is stable, and saves material.
As further improving again; The upper strata square frame of base section steelframe is provided with vertically to the hole; And also be provided with vertical bolt via hole on the standard knot steelframe of middle-size and small-size tower motor spindle; Like this, can utilize pass this base section steelframe vertically be spirally connected the standard knot steelframe of this base section steelframe and middle-size and small-size tower motor spindle fixing to the bolt of the bolt via hole of hole and standard knot steelframe.
As also further improving; Be welded with the second split heads muscle on lower floor's steel mesh reinforcement of reinforced concrete footing; Lower floor's square frame spot welding of the end face of the second split heads muscle and base section steelframe is fixed; Like this, can the lower floor's steel mesh reinforcement and the base section steelframe of concrete bed be fixed through the second split heads muscle, base section steelframe occurred level is to displacement when preventing the concrete of casting reinforced concrete base.
