Description
Technical field
The utility model relates to a kind of lattice tower cranes, belong to technical field of building construction.
Background technique
In modern construction engineering, tower crane is as a kind of lifting equipment most common on construction site, using just further frequently.
Rationally correctly tower crane can not only save engineering cost, moreover it is possible to avoid loss brought by potential security risk.For
The construction of deep basal pit generallys use lattice tower crane, the common support tower of the lattice column to be installed on each bored concrete pile top
Hang basic platform.For common lattice tower crane independently of the structure of surrounding, such tower crane needs are that basic tower crane is beaten
If independent bored concrete pile and lattice column, there are construction costs it is high, overall stability is poor the disadvantages of.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of lattice tower cranes, can be mixed using reinforcing bar
Solidifying soil support trestle is as tower crane, it is no longer necessary to set up special lattice column and bored concrete pile for tower crane cushion cap.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
A kind of lattice tower crane, including four hold-down support built-in fittings and the tower being mounted on hold-down support built-in fitting
Superstructure is hung,
The hold-down support built-in fitting is embedded in and trestle beam slab formed by integrally casting and the consistent right-angled intersection steel of top surface absolute altitude
On reinforced concrete foundation beam cushion cap, four of the right-angled intersection reinforced concrete foundation joist support platform are each embedding between apex angle and bottom plate
If a steel lattice column, the steel lattice column passes through the reinforced concrete support and bottom plate below the trestle beam slab, steel latticework
The bottom end of column is embedded in the cast-in-place concrete pile below the bottom plate.
Further, the periphery of the right-angled intersection reinforced concrete foundation joist support platform is equipped with anticollision barricade.
Further, the anticollision barricade is reinforced concrete structure or steel construction.
Further, horizontal cross brace and vertical bridging are welded between adjacent steel lattice column.
Further, the horizontal cross brace and vertical bridging are made of channel steel.
The principles of the present invention are, since right-angled intersection reinforced concrete foundation joist support platform is integrally poured with trestle beam slab
It builds, the lattice column that tower crane load passes through under trestle beam slab transmits downwards, can be from setting independent steel in foundation beam cushion cap periphery
Lattice column and pour support of the special bored concrete pile as tower crane.Simultaneously tower crane be connected with trestle beam slab and
Lattice column is connected with concrete support, each contributes to the enhancing integrally-built stability of tower crane.Introduce horizontal cross brace and
Vertical bridging can further strengthen the connection between adjacent steel pile, to provide more stable support for tower crane.
To sum up, compared with prior art, the utility model has the beneficial effects that: the lattice tower crane base of the utility model
Plinth stable structure is reliable, and when construction can set lattice column and bored concrete pile from being individually for tower crane cushion cap, keeps construction cost aobvious
Writing reduces, while being also avoided that the independent box out on basement floor, and the construction for subsequent basement floor provides convenience.Tower crane
The effect on basis and trestle beam slab group effect, keeps tower crane more stable and safe.
Detailed description of the invention
Fig. 1 is the top view of one preferred embodiment of the utility model.
Fig. 2 is the sectional view of one preferred embodiment of the utility model.

Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It is said according to following
Bright, the purpose of this utility model, technical solution and advantage will be apparent from.It should be noted that described embodiment is this
The preferred embodiment of utility model, instead of all the embodiments.
Referring to figs. 1 and 2, a kind of lattice tower crane, including four hold-down support built-in fittings 7 and it is mounted on institute
The tower crane superstructure 6 on hold-down support built-in fitting 7 is stated, the hold-down support built-in fitting 7 is embedded in right-angled intersection reinforced concrete
On earth foundation joist support platform 1, the right-angled intersection reinforced concrete foundation joist support platform 1 is with 2 formed by integrally casting of trestle beam slab and top surface is marked
It is high consistent.A steel latticework is respectively embedded between four apex angles and bottom plate 4 of the right-angled intersection reinforced concrete foundation joist support platform 1
Column 3, the top of the steel lattice column 3 are embedded into right-angled intersection reinforced concrete foundation joist support platform 1, and shaft runs through trestle beam slab
The reinforced concrete support 11 and bottom plate 4 of 2 lower sections, the bottom end of steel lattice column 3 are embedded in the cast-in-place concrete pile of 4 lower section of bottom plate
In 5.That is, the upper end support trestle beam slab 2 and right-angled intersection reinforced concrete foundation joist support platform 1 of steel lattice column 3, lower end
Cast-in-place concrete pile 5 is delivered load to through reinforced concrete support 11 and bottom plate 4.
In the work progress of deep basal pit, it can be exempted from using the lattice column 3 and cast-in-place concrete pile 5 that support under trestle beam slab 2
In setting steel lattice column in 1 periphery of right-angled intersection reinforced concrete foundation joist support platform and pour special bored concrete pile as tower crane base
The support of plinth.But armored concrete trestle supports cushion cap tower-crane foundation structure stress more complex, and this kind of tower crane is in setting
Force request need to be met.
The periphery of the right-angled intersection reinforced concrete foundation joist support platform 1 is equipped with anticollision barricade 8.The anticollision barricade 8 is
Reinforced concrete structure or steel construction.
In conjunction with Fig. 2 and Fig. 3, horizontal cross brace 9 and vertical scissors made of channel steel are welded between adjacent steel lattice column 3
Support 10.
The lattice tower-crane foundation structure of the utility model is reliable and stable, and when construction can be from being individually for tower crane cushion cap
Special lattice column and bored concrete pile are set, construction cost is significantly lower.The effect of tower crane and trestle beam slab group effect, institute
It is more stable and safe to state tower crane.
The above is only the description explanation of the preferred embodiment in the utility model, not to scope of protection of the utility model
Restriction, it is clear that anyone skilled in the art based on the above embodiment, can readily occur in replacement or variation to obtain
Other embodiments, these, which should all cover, is within the protection scope of the utility model.
