Abstract
The utility model relates to a tower crane base and belongs to the tower crane technical field. The tower crane base comprises four drilled grouting piles and is characterized in that the top end of each drilled grouting pile is provided with a steel latticed column in a fitting mode. A platform is arranged at the top end of the four steel latticed columns. A tower crane is arranged on the platform. The tower crane base has the advantages of being simple in structure, convenient to install on site, fast in construction speed, light and handy and firm, and greatly reducing cost of construction due to the fact that the platform and the steel latticed columns can be recycled and utilized, not occupying earthwork excavation construction period and greatly reducing construction period and project amount of an earthwork construction stage.
Description
Technical field
The utility model belongs to the tower crane technical field, is specially a kind of tower crane.
Background technology
At present, in existing tower crane construction technology, mostly adopt the tower crane of reinforced concrete structure, its advantage is that construction technology is ripe, and reliability is high, but it is larger to build tower crane concrete Foundation Design amount, tower crane concrete basis needs maintenance a period of time to reach the design strength requirement, often takies other operations duration, and, tower crane concrete basis can not reuse, sometimes in addition construction be difficult to process after finishing.This shows that there is long, the problem such as engineering quantity large, can not reuse of construction period in tower crane concrete basis.
The utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that a kind of tower crane is provided, on-the-spot easy for installation, speed of application is fast, the construction period is short, light and handy firm, and platform and all reusable edible or recovery of steel lattice column greatly reduce cost.
Described a kind of tower crane comprises four bored piles, it is characterized in that every bored pile top is equipped with steel lattice column, and four steel lattice column tops are equipped with platform, and tower crane is installed on the platform.
Described a kind of tower crane is characterized in that the interlocking of bored pile top arranges steel lattice column, and the degree of depth of steel lattice column inlay bur hole pouring pile is 2.5-3.5 rice.
Described a kind of tower crane is characterized in that being equipped with the shearing support between each adjacent steel lattice column.
Described a kind of tower crane is characterized in that platform cooperates with each steel lattice column top welding, and adopts steel gusset reinforcement of weld.
Described a kind of tower crane is characterized in that described platform is made of steel plate, channel-section steel welding.
Described a kind of tower crane is characterized in that described shearing support is made of horizontal connecting rod and the welding of oblique connecting rod.
Above-mentioned a kind of tower crane, simple in structure, on-the-spot easy for installation, speed of application is fast, and is firmly light and handy; Platform and steel lattice column reusable edible or recovery greatly reduce cost; And adopt this tower crane, do not take the cubic metre of earth and stone and excavate the duration, can greatly reduce duration in restoration in earth-rock construction stage and engineering quantity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is platform schematic diagram of the present utility model;
Among the figure: 1-bored pile, 2-steel lattice column, 3-shearing support, 4-platform, 4a-steel plate, 4b-channel-section steel, 5-steel gusset, 6-tower crane.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in the figure, this tower crane comprises four bored piles 1, and every bored pile 1 top is equipped with 2, four steel lattice column 2 tops of steel lattice column and is equipped with platform 4, on the direct mounting platform 4 of tower crane 6 usefulness bolts.The interlocking of bored pile 1 top arranges steel lattice column 2, and the degree of depth of steel lattice column 2 inlay bur hole pouring piles 1 is 2.5-3.5 rice, stable connection.Be equipped with shearing support 3 between each adjacent steel lattice column 2, described shearing support 3 is made of horizontal connecting rod and the welding of oblique connecting rod, and four steel lattice columns 2 are reinforced into whole by shearing support 3.Platform 4 cooperates with each steel lattice column 2 tops welding, and adopts steel gusset 5 reinforcement of welds.Described platform 4 is made of two steel plate 4a and eight channel-section steel 4b welding.Bored pile 1 is that the tower crane of installing is special-purpose, the position of four bored piles 1 and spacing meet the institute desired position of installation tower crane and underlying parameter, and tower crane 6 weight are distributed to the center line of four steel lattice columns 2 of center line and bottom of four installation feet and tower crane Special drill castinplace pile 1 center line on same straight line.This tower crane is owing to adopted full steel structure, and on-the-spot easy for installation, speed of application is fast, and the construction period is short, and is firmly light and handy, and platform and steel lattice column reusable edible or recovery, greatly reduces cost.
