Abstract
The utility model discloses a detachable concrete prefabricating assembled tower crane foundation, which is formed by fixedly assembling a concrete prefabricated center component, a support part, a transition part and end parts. End surfaces of the center component are all sequentially connected with the support part, the transition part and the end parts, and the support part is provided with foundation bolts. The detachable concrete prefabricated assembled tower crane foundation is strong in integral stability, simultaneously is convenient in detachment and can be recycled. In addition, the detachable concrete prefabricated assembled tower crane foundation has the advantages of convenient, fast, general, economical and practical properties and the like, is small in occupied area and large in relative earthing area, and can be applicable to regions with lower foundation bearing force.
Description
Technical field:
The utility model relates generally to the foundation for tower crane of building field, relates in particular to a kind of dismountable concrete precast assembly foundation for tower crane.
Technical background:
In the use of pillar crane, tower crane foundation occupies critical role, and still, tower crane foundation design does not at present still have standard and can comply with, the Cast-in-situs type reinforced concrete foundation is generally adopted in countries in the world, and there is following limitation in this basis: (1), long in time limit.Remove on basis after foundation dredging, basic making, concrete curing and even tower machine are finished using, all need take a long time; (2), expense height.Remove from the basis of foundation dredging after finish using, and the disposal of the building waste of foundation for tower crane all need spend more expense; (3), do not reach civilized construction and environmental protection requirement.On-the-spot cast-in-situ steel reinforced concrete column foot inevitably can influence surrounding environment, produces building waste, does not reach civilized construction and requirement on environmental protection; (4), can not reuse.On-the-spot cast-in-place fixedly foundation for tower crane is of a great variety, and form is different, and versatility is poor, and relative fixed generally can not be reused again; Influence the later stage engineering construction, need cost manually to pound cutter or explosion treatment in a large number under some situation.
Patent Office of the People's Republic of China discloses a kind of combination foundation for tower crane of square rood beam plated construction with notification number CN201003171Y, has overcome many shortcomings of Cast-in-situs type reinforced concrete foundation substantially, have assembling and dissembling speed fast, economize on resources, feature such as environmental protection.But its prefabricated section spare is complicated, and contact area is little and relative floor space is big, has limited in the use of bearing capacity of foundation soil than low country, and the shearing resistance male and female member is set between each piece spare, and is higher relatively to the making requirement of prefabricated component.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of dismountable concrete precast assembly foundation for tower crane is provided, its rounded beam and slab structure in combination back, resistance to overturning is strong, the basis floor space is little and relative contact area is big, reduce the bearing capacity of foundation soil requirement, enlarged the scope of application.
The utility model is achieved through the following technical solutions:
A kind of dismountable concrete precast assembly foundation for tower crane, it is characterized in that: described foundation for tower crane splices the beam slab circular configuration that is assembled into by the fan-shaped assembly in each end face outside around concrete prefabricated square center element and the center element, and described fan-shaped assembly includes seat member, transition piece and extremity piece; Described seat member be provided with stone bolt; Seat member, transition piece and extremity piece are down " T " font, are cross beam slab circular configuration with whole basis, center element combination back.
Described dismountable concrete precast assembly foundation for tower crane is characterized in that the body internal upper part of described seat member, transition piece and extremity piece is penetrated with a duct that supplies steel strand to pass, and the bottom is penetrated with two ducts that supply steel strand to pass; Corresponding with the duct on seat member, transition piece and the extremity piece, be penetrated with six ducts that supply steel strand to pass in the center element body; The steel strand that are arranged in the described duct by stretch-draw are assembled into integral body with each assembly.
The utility model adopts 13 concrete prefabricated assemblies, whole basis, combination back " ten " font beam slab circular configuration axisymmetricly, and its floor space is little and relative contact area is big; And form each the piece spare of prestress steel twist bundle of lines that is arranged in the duct by stretch-draw respectively in the corresponding duct in the combination back rest body and be assembled into an integral body, its stability is stronger, described foundation for tower crane joint connects with seat member by stone bolt, can arrange different stone bolt according to different tower machine models, the difference that is different tower machine models only is embodied on the seat member, and other prefabricated section spare can be general.
The utility model has the advantages that:
1. convenient, fast, reusable, economic benefits are given prominence to;
2. floor space is little and relative contact area is big, applicable to the lower area of bearing capacity of foundation soil;
3. the difference on different tower machine model bases only is embodied on the seat member, and other prefabricated section spare can be general, and whole versatility is stronger.
Description of drawings:
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model cross-sectional view.
Fig. 3 is a design sketch before the utility model 1/4 assembling.
Fig. 4 is a design sketch after the utility model overall package.
The specific embodiment:
Referring to Fig. 1,2, a kind of dismountable concrete precast assembly foundation for tower crane includes concrete cushion 7, foundation for tower crane, on the described concrete cushion 7 foundation for tower crane is installed; Described foundation for tower crane fixedly is assembled by concrete prefabricated center element 1 and the fixedly connected fan-shaped assembly of each end face of center element, and described fan-shaped assembly includes seat member 2, transition piece 3 and extremity piece 4; End face offers three ducts 6 respectively on seat member 2, transition piece 3 and extremity piece 4 by orthogonal two directions around the described center element 1, arrange that by stretch-draw steel strand are in duct 6, make the assembling of assembling type base in aggregates, the steel strand of two vertical direction intersect in center element 1 body, spatially dodge mutually in the duct 6 of two vertical direction in center element 1 body, the top of described seat member 2 is provided with stone bolt 5, is used to install the tower crane joint.
Stone bolt 5 on the seat member 2 is to arrange according to different tower machine models.
