Abstract
It the utility model is related to the tower-crane foundation structure that building surrounding is covered in suitable for multi-layer underground building.Tower-crane foundation structure includes the tower body of building underground structure, tower crane and tower crane；Building underground structure includes more than one layer of hypogee and bottom plate or raft plate, tower crane base pitch and standard knot are sequentially connected composition；Improvement is：Tower crane one-piece casting is on bottom plate or raft plate；Tower body passes through more than one layer of hypogee, and the lower end of the tower crane base pitch of tower body foot is fixed on tower crane.Tower-crane foundation structure of the present utility model avoids increases supporting construction similar to lattice column for construction tower crane, and constructing operation is simple and convenient, and safety guarantee coefficient is big, does not influence underground main structure construction, effectively reduces working measure and takes.
Description
Technical field
The utility model belongs to building engineering technical field, and in particular to the tower crane installation suitable for architectural engineering is applied
Work.
Background technology
In building engineering, in especially present more single buildings of the big scale of construction and integral multi-layered construction of underground structure,
Part tower crane directly can not construct on foundation, be made troubles to tower crane construction and installation use.Currently, have and much apply
Work order position adds lattice column to be supported as tower crane using cast-in-situ bored pile, and lattice column stretches out underground structure top board, tower crane
It is cast on lattice column.Such a tower-crane foundation structure has the following disadvantages：1. lattice pillar tower crane complicated construction technique, into
This is higher, and safety wind is dangerous big；2. in lattice column insertion cast-in-situ bored pile, the difficult control of construction quality, quality directly affects
Tower crane bearing capacity；3. pouring tower crane on lattice column again, equivalent to sky assembling reinforcement is faced, supporting module, coagulation is poured
Soil, difficulty of construction are big.
Utility model content
Farthest to ensure tower crane construction safety, easy for construction and economic, the utility model provides a kind of suitable
The building tower-crane foundation structure of building surrounding is covered in for multi-layer underground building.
Specific technical solution is as follows：
The tower-crane foundation structure of building surrounding, including building underground structure, tower are covered in suitable for multi-layer underground building
Hang basis（1）With the tower body of tower crane；The building underground structure includes more than one layer of hypogee and bottom plate or raft plate 2,
The tower body of tower crane is sequentially connected and formed by base pitch and standard knot 4；Improvement is：
The one-piece casting of tower crane 1 is on bottom plate or raft plate 2；
The tower body passes through more than one layer of hypogee, and the lower end of the tower crane base pitch of tower body bottom is fixed on tower crane
1。
The technical scheme further limited is as follows：
When bottom plate or raft plate 2 are constructed after tower crane 1, steel plate for sealing water 9 is embedded with advance on tower crane 1.
The building underground structure also includes the pile foundation 8 being made up of the pile of more than four, and the tower crane 1 is set
In in pile foundation 8.
Described more than one layer of hypogee includes underground negative one floor plate 5, the minus two floors plate 6 in underground and underground structure top
Plate 7.
Advantageous effects of the present utility model embody in the following areas：
1. the utility model tower crane 1 on the bottom plate or raft plate 2 in hypogee, is avoided as tower crane base of constructing
Plinth and increase the supporting construction similar to lattice column, effectively reduce working measure take.
2. standard section of tower crane 4 passes through hypogee floor and top plate, constructing operation is simple and convenient, and safety guarantee coefficient is big,
Underground main structure construction is not influenceed, and its economic benefit is constructed also above the tower crane of other modes.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is Fig. 1 tower crane profile.
Fig. 3 is the utility model structural representation for having pile foundation.
Fig. 4 is Fig. 3 tower crane profile.
Sequence number in upper figure：Tower crane 1, bottom plate or raft plate 2, bed course 3, standard section of tower crane 4, underground negative one floor plate 5,
Under minus two floors plate 6, underground structure top board 7, pile foundation 8, steel plate for sealing water 9, pre-embedded bolt 10.
Embodiment
Below in conjunction with the accompanying drawings, by embodiment, the utility model is further described.
Embodiment 1
Referring to Fig. 1 and Fig. 2, the tower-crane foundation structure of building surrounding is covered in suitable for multi-layer underground building includes building
The tower body of underground structure, tower crane 1 and tower crane.
Building underground structure includes underground negative one floor plate 5, the minus two floors plate 6 in underground, underground structure top board 7 and bottom plate
Or raft plate 2.The tower body of tower crane is sequentially connected and formed by tower crane base pitch and standard section of tower crane 4.
Improvement is：The one-piece casting of tower crane 1 is on bottom plate or raft plate 2；Tower body through underground structure top board 7,
Under minus two floors plate 6 and underground negative one floor plate 5, the lower end of the tower crane base pitch of tower body foot is fixed on tower crane 1.
Embodiment 2
Referring to Fig. 3 and Fig. 4, when natural characteristic value of foundation bearing capacity is insufficient for tower crane requirement for bearing capacity, then tower of constructing
Before hanging basis 1, four pile foundations 8 of first constructing, for improving the bearing capacity of tower crane 1.Tower crane 1 is arranged in pile foundation 8.
Pile foundation 8 is generally four pile foundations, but is not limited to four.
