Abstract
The utility model discloses a kind of combined type of spread foundation adding rock anchor pole bases, including the rock foundation, bed course and spread foundation set gradually from top to bottom；The combined type basis further includes rock-bolt, and the lower end of the rock-bolt anchors into rock foundation, and the upper end of the rock-bolt passes through the bed course and anchors with the spread foundation.The utility model structure is simple, is linked together spread foundation and rock foundation by rock-bolt, while enhancing spread foundation bending resistance, antidumping equal strength requires, reduces the excavated volume and base concrete amount of rock foundation, to accelerate construction speed.
Description
Technical field
The utility model relates to technical field of building construction, and in particular to a kind of combined type of spread foundation adding rock anchor pole
Basis and tower crane.
Background technique
As urban land is fewer and fewer and underground space development, the under ground portion of building is increasing, deeper and deeper,
Basement bottom board reach substantially to middle weathering or more than rock stratum.In building trade, tower crane be to building engineering construction material into
The important means of the horizontal and vertical transport of row.Existing tower crane is generally located under basement bottom board, mainly uses spread foundation
Form.In order to meet antidumping requirement, foundation platform size is larger, and size is not able to satisfy tower crane much between building basis
Arrangement, not only influenced building basis, and but also affected the arrangement of tower crane, for this purpose, being badly in need of a kind of easy for construction and being able to satisfy
It is required that basal profile.
Utility model content
The utility model is in view of the deficiencies of the prior art, to provide a kind of combined type of spread foundation adding rock anchor pole
Basis and tower crane reduce basement rock excavation and amount of concrete while meeting bending resistance, shearing resistance, the requirement of antidumping equal strength,
Shorten the construction time.
The utility model is achieved through the following technical solutions:
The utility model first aspect provides a kind of combined type basis of spread foundation adding rock anchor pole, including from it is lower to
On the rock foundation, bed course and the spread foundation that set gradually, further include rock-bolt, the lower end of the rock-bolt anchors into rock
Ground, the upper end of the rock-bolt pass through the bed course and anchor with the spread foundation.
By the way that rock-bolt is arranged, spread foundation and rock foundation can be linked together, substantially increase spread foundation
Bending resistance, shearing resistance and anti-overturning.
Further, the rock-bolt is made of symmetrical dowel, and the dowel is in inverted L shape.
Further, the bed course is concrete cushion.
Further, the spread foundation is reinforced concrete foundation.
In addition, the utility model second aspect also provides a kind of tower crane, the tower crane is mounted on the spread foundation and adds rock
On the basis of the combined type of killagh bar.
On the basis of tower crane is mounted on the combined type, the key dimension of tower crane is effectively reduced, while also strengthening tower
Hang the anti-overturning energy on basis.
Compared with prior art, the utility model has the beneficial effects that
The utility model is structurally reasonable, easy for construction, on the basis of tower crane is mounted on the combined type, effectively reduces tower
The size on basis is hung, and then reduces the excavated volume of rock foundation, greatly accelerates construction speed.At the same time, rock-bolt
Top tower crane moment of flexure caused by heavy load, wind load etc. by can be born, the anti-overturning energy of spread foundation can be effectively improved, is protected
The safe operation of tower crane work is demonstrate,proved.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
One embodiment for those of ordinary skill in the art without any creative labor, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is the overall structure diagram of the utility model.
Wherein, the meaning of appended drawing reference is as follows:
Rock foundation 1, bed course 2, spread foundation 3, tower crane 4, bolthole 5, rock-bolt 6.
Specific embodiment
In order to better understand and implement, with reference to the accompanying drawings and examples, to specific embodiment of the present utility model
It is described in further detail.Following embodiment is merely to illustrate the utility model, is not intended to limit the scope of the present invention.
The utility model discloses a kind of combined type of spread foundation adding rock anchor pole basis and tower cranes, as shown in Figure 1, packet
Include the rock foundation 1 set gradually from top to bottom, bed course 2, spread foundation 3 and tower crane 4.It in addition to this, further include rock-bolt
6.Bolthole 5 is offered on the rock foundation 1, the lower end of the rock-bolt 6 is inserted and fixed the bolthole 5
Interior, the upper end of the rock-bolt 6 passes through the bed course 2 and anchors with the spread foundation 3.
In the present embodiment, the bed course 2 is concrete cushion；The spread foundation 3 is reinforced concrete foundation；It is described
Rock-bolt 6 is made of symmetrical dowel, and the dowel is in inverted L shape.
By the way that rock-bolt 6 is arranged, spread foundation 3 and rock foundation 1 can be linked together, effectively increase spread foundation
3 anti-overturning energy plays moment of flexure caused by heavy load, wind load etc. and vertical load with this to bear top tower crane 4 jointly, protects
The safe operation of the work of tower crane 4 is demonstrate,proved.
The working principle of the utility model is as follows:
The diameter of rock-bolt 6, length and required radical are determined by calculation out first, arranges rock-bolt 6
The distance between after, corresponding bolthole 5 is opened up on rock foundation 1, the lower end in rock-bolt 6 is inserted and fixed
In bolthole 5.The then casting concrete bed course 2 on rock foundation 1, and build reinforcing bar on concrete cushion 2 and pour mixed
Solidifying soil forms spread foundation 3, and the upper end of rock-bolt passes through the concrete cushion 2, and is cast in concrete spread foundation 3
It is interior, to spread foundation 3 and rock foundation 1 are linked together, with load brought by this common receiving top tower crane 4.
Technological means disclosed in the utility model is not limited only to technological means disclosed in above embodiment, also
Including technical solution consisting of any combination of the above technical features.It should be pointed out that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
