Description
Technical field
The present invention relates to the construction field of derrick crane, concretely relate to the double pre-buried joint of a kind of tower crane and construction thereof
Method.
Background technology
Along with the increase of construction project scale, the tower crane of conventional model cannot meet construction requirement, the most large-scale public affairs
Build in project and multi-storey basement project, often there is local or specific construction part, it is necessary to use the tower crane of larger number to replace
The generation tower crane of conventional model is constructed.
Pre-buried joint for be embedded in concrete foundation in advance, the portion being connected with foundation for tower crane joint or the superstructure such as standard knot
Point, be typically different the tower crane of model and need to arrange in pairs or groups the pre-buried joint of respective model is installed, the specification of tower crane model the most pre-buried different joint and
Form is the most different, and the tower crane of different model cannot use the pre-buried joint of same to construct.
Meanwhile, the size of concrete foundation, arrangement of reinforcement etc. require to carry out respective design, if by difference also according to the model of tower crane
The tower crane of model arbitrarily uses the different tower crane that the concrete foundation cushion cap of same model, especially performance parameter differ bigger with,
Will result in bigger potential safety hazard, even result in tower crane and the security incident such as topple.
If desired use different model tower crane in the different construction stages, then original concrete foundation cushion cap must be carried out weight
New construction, makes the tower crane concrete foundation cushion cap meeting construction requirement.But, construction concrete foundation cushion cap is not only subject to again
To the strict restriction of site condition, also it is greatly increased construction cost, affects the normal progress of construction, unfavorable to construction.
Therefore, practice of construction the most just considers large-scale tower crane is installed, and large-scale tower crane lease, use etc. take
With costly, roll up the input of construction cost.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide the double pre-buried joint of a kind of tower crane and construction party thereof
Method, effectively solves the technical barrier that size type tower crane is replaced in construction, not only greatly reduces tower crane operating cost, it is ensured that
The job safety of tower crane displacement, structural safety is reliable, simple to operation.
For achieving the above object, the technical scheme is that the double pre-buried joint of a kind of tower crane, including the most pre-buried
Joint, little pre-buried joint, connecting rod, bearing diagonal and brace.Wherein, little pre-buried joint is arranged in big pre-buried joint, and little pre-buried joint is with the most pre-buried
Joint is connected by connecting rod.
Preferably, in described little pre-buried joint, it is provided with bearing diagonal and brace, in big pre-buried joint, also is provided with brace, increase structure
Bonding strength.
Preferably, described connecting rod is arranged on big pre-buried joint diagonal position, is connected with the supporting leg of little pre-buried joint, both can play
Interconnection function may also function as skewed horizontal load effect, strengthens structural integrity.
Preferably, described big pre-buried joint is parallel with little pre-buried joint upper surface, it is ensured that the flatness of upper surface.
Preferably, described big pre-buried joint and little pre-buried joint are cast in same concrete foundation cushion cap.
Preferably, the described size of concrete foundation cushion cap, arrangement of reinforcement etc. require to be satisfied by the design requirement of big pre-buried joint.
Preferably, described connecting rod, bearing diagonal and brace are all fixed by welding in structure.
Preferably, described big pre-buried joint and little pre-buried joint are in the double pre-buried joint of same tower crane, by same specialized factory
Design and produce.
Present invention also offers the construction method of the double pre-buried joint of a kind of tower crane, the technical scheme used mainly includes following
Step:
Step one: make the double pre-buried joint of tower crane so that it is the tower crane meeting two kinds of different models uses, it is ensured that big pre-buried joint is pre-with little
Bury joint upper surface parallel；
Step 2: design tower crane concrete foundation cushion cap by big model foundation for tower crane requirement；
Step 3: earth excavation to absolute altitude at the bottom of column foot cap design of pile, the double pre-buried joint embedment precalculated positions of colligation cushion cap reinforcing bar also general,
The length of embedment of double pre-buried joints is satisfied by designing requirement with stretching out foundation platform height, and the installation completing double pre-buried joint is fixed；
Step 4: install template, casting concrete foundation platform.
Further, in described step 3, during double pre-buried joint integral built-in, it is ensured that levelness is in 1 ‰.
The invention has the beneficial effects as follows: the double pre-buried joint of a kind of tower crane and construction method thereof, embedded little pre-buried with big pre-buried joint
The integral form of joint buries as in tower crane concrete foundation, it is not necessary to the most embedding, not only efficiently solves big small-sized tower crane in construction
The technical barrier of middle displacement, greatly reduces tower crane operating cost, it is ensured that the job safety of tower crane displacement, on double pre-buried joints
The flatness on surface is guaranteed the most simultaneously, and only need to pour tower crane concrete foundation once reduces difficulty of construction, ensures
Construction speed, this device good integrity, double pre-buried joint location, pre-buried accuracy have been effectively ensured, fixing simple, operation side
Just.
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
