Abstract
The invention relates to a prefabricated foundation, in particular to a prefabricated tower and mast structure foundation, belonging to the technical field of construction engineering. The prefabricated tower and mast foundation comprises an inner cylinder, a bottom plate and a counterweight ring, and all the components are prefabricated in a factory and assembled into a whole at the construction field, wherein the inner cylinder is placed on the bottom plate, and the counterweight ring is sleeved outside the inner cylinder and self-locked on the inner cylinder by self weight to form a whole foundation. The prefabricated foundation is assembled without the aid of pre-stressed tendons or bolts and other traditional assembling means, but is assembled by a gravity self-locking effect generated by the self weights of the components, therefore, installation of the prefabricated foundation is more convenient, quicker and lower in cost compared with the traditional prefabricated foundations, and the foundation can be conveniently disassembled to realize repeated use.
Description
Technical field
The present invention relates to a kind of prefabricated assembled basis, particularly relate to a kind of prefabricated assembled tower mast structure basis, belong to construction engineering technical field.
Background technology
Along with the Chinese society expanding economy, in construction project, all kinds of tower mast structures as: the application of tall and slender structures such as communications tower, high lamp stand, billboard constantly increases.The main cast-in-situ steel reinforced concrete base form that adopts in the basis of present domestic tower mast structure.The cast-in-situ steel reinforced concrete basis needs formwork, bundle muscle, fluid concrete at the construction field (site), and can install portion's structure after needing the base concrete maintenance to reach design strength.The cast-in-situ concrete foundation construction cycle is long, and is big to the job site ambient influnence, and the basis can only disposablely use, and is prone to produce building waste, causes the wasting of resources, do not meet the requirement of environmental protection and civilized construction.Therefore, need the prefabricated basis that exploitation is suitable for to tower mast structure, with satisfy the special construction environment as: construction can not influence scene and surrounding enviroment and special construction condition like the requirement of duration anxiety in the urban district.Prefabricated basis is prefabricated in the factory, and quality is guaranteed; Generally do not need wet trade, quick construction at the construction field (site); Prefabricated basis can also be reused, and meets the requirement of environmental protection and civilized construction.But when prefabricated basis was used for bigger structure, the basic scale of construction was huge, if integral manufacturing is then made, transports, installs all inconvenient.Therefore, the necessary precast block in large scale prefabricated basis is assembled into integral body again to the job site.The erection method on present prefabricated basis mainly contains: back pouring concrete assembly unit, presstressed reinforcing steel assembly unit, bolt assembly unit.Back pouring concrete assembly unit needs the cast on-site concrete, can cause claim for eot; Presstressed reinforcing steel assembly unit and bolt assembly unit meeting make basic mounting technique complicacy and cause basic cost to rise.Therefore seek the basic piecemeal of advantages of simple and a key and the difficult problem that erection method is prefabricated assembled basis.
Summary of the invention
The objective of the invention is for overcoming the weak point of above-mentioned prior art, a kind of prefabricated assembled tower mast structure basis is provided, this prefabricated assembled tower mast basis includes inner core, base plate and counterweight ring, and each member is assembled into integral body at the construction field (site) by prefabrication.Inner core is shelved on the base plate; The side dependence outer tube of counterweight ring set is self-locking on the inner core, forms base integral.The assembly unit on this prefabricated basis need be by traditional assembly unit means such as presstressed reinforcing steel or bolts; But " the gravity self-locking effect " of leaning on member dead weight to produce realizes basic assembly unit; Therefore the more traditional prefabricated basis of the installation on this prefabricated basis is more convenient, quick; Expense is lower, and the basis can be dismantled the realization repeated use easily.
The present invention realizes with following technical scheme: a kind of prefabricated assembled tower mast structure basis; It includes inner core (1), base plate (2) and counterweight ring (3); Inner core is seated on the base plate; It is characterized in that: described inner tank theca is up-small and down-big truncated cone, is with some counterweight rings on the inner tank theca from top to bottom; The inwall of described counterweight ring is up-small and down-big truncated cone, and the counterweight ring relies on deadweight to form integral body from locking on the inner core with inner core, between each counterweight ring and between counterweight ring and the base plate vertical gap is arranged.
Described inner core is a hollow shape, the sealing of inner core end face, and there is circular open the bottom surface, and connecting bolt is arranged at the inner core top, and inner core is fixed through connecting bolt and top tower mast structure.
The shear key that truncated cone is arranged in the middle of the described plate upper surface.
The invention has the beneficial effects as follows: the assembly unit on this prefabricated assembled basis does not need cast-in-place concrete, need be by traditional assembly unit means such as presstressed reinforcing steel or bolts yet, but " the gravity self-locking effect " that rely on member dead weight to produce realizes the assembly unit on basis.The assembly unit simple and fast on basis, cost is low, and is safe and reliable.Basic requirement to different loading conditions and different ground situation can realize through the quantity of adjustment counterweight ring and the size of counterweight ring, helps realizing the standardization and the modularization production on prefabricated basis.The basis convenient disassembly, the situation that basic presstressed reinforcing steel that can not occur being prone in traditional erection method or bolt rust are waited indefinitely and be difficult to dismantle, the basis is reusable, meets the building requirements of environmental protection.

Among the figure, 1, inner core, 2, base plate, 3, the counterweight ring, 4, bolt, 5, shear key.
The specific embodiment
As shown in the figure: a kind of prefabricated assembled tower mast structure basis, it includes inner core 1, base plate 2 and counterweight ring 3, and inner core is seated on the base plate 2, and described inner core 1 outer wall is up-small and down-big truncated cone, is with some counterweight rings 3 on the inner tank theca from top to bottom; The inwall of described counterweight ring is up-small and down-big truncated cone, and the counterweight ring relies on deadweight to form integral body from locking on the inner core with inner core, between each counterweight ring and between counterweight ring and the base plate vertical gap is arranged.
Described inner core 1 is a hollow shape, the sealing of inner core end face, and there is circular open the bottom surface, and connecting bolt 4 is arranged at the inner core top, and inner core is fixed through connecting bolt and top tower mast structure.
The shear key 5 that truncated cone is arranged in the middle of described base plate 2 upper surfaces.
Described each member can be made in the factory for prefabrication, and inner core, base plate and counterweight ring can adopt Reinforced Concrete Materials to make, and wherein inner core also can adopt steel to make, and steel surface need carry out preservative treatment.
The course of work: according to basic part size excavation pit; The bed course levelling is done in the foundation ditch bottom, puts into base plate; Sit slurry back mounting inner cylinder on the base plate, the shear key interlock that inner core bottom surface circular hole and base plate are protruding; The counterweight ring is installed on inner core; Pit backfill soil and compacting; The top tower mast structure is installed.This basic part can be dismantled repeated use, and disassembly sequence and erection sequence are opposite.
