Description
Technical field
The utility model relates to transmission tower technical field, especially relates to a kind of basis of transmission tower.
Background technology
Existing transmission tower foundation is generally by pre-embedded anchoring bolts in concrete with the connection of transmission tower, stone bolt is connected with the column foot plate of transmission tower, column foot plate is placed directly on the end face on basis, is admittedly connected with the matching used nut of stone bolt by twisting.Shaft tower passes to the shearing that basic power comprises pulling force, pressure and horizontal direction to basic vertical direction, and this part shearing will pass to basis by stone bolt.The shear stress that can bear because of it due to stone bolt makes its tensile strength reduce, and thus its rate of utilization of strength is not not fully exerted.Further, when basic role power is large or horizontal force is large, can there is small slip in stone bolt, and then affect the stability of transmission tower.
Utility model content
Based on this, the utility model is the defect overcoming prior art, provides a kind of basis of transmission tower, and it can less horizontal shear be on the impact of transmission tower effectively, and improve stone bolt rate of utilization of strength, the safety being conducive to transmission tower is fixed.
Its technical scheme is as follows:
A kind of basis of transmission tower, transmission tower is fixed on described basis, transmission tower is provided with column foot plate near the one end on described basis, described basis is arranged with the shearing groove with described column foot plate form fit, be embedded with at least one stone bolt in described shearing groove, described column foot plate is provided with the fixing hole coordinated with described stone bolt.
Wherein in an embodiment, the degree of depth of described shearing groove is not less than the thickness of described column foot plate.
Wherein in an embodiment, described shearing groove is arranged at the end face central area on described basis.
Wherein in an embodiment, in described basis, be also provided with the distribution bar arranged around described shearing groove.
Wherein in an embodiment, described stone bolt is multiple, and multiple described stone bolt is circumferentially evenly arranged around the center of described shearing groove.
The beneficial effects of the utility model are:
The basis of transmission tower provided by the utility model is made up of concrete casting, it is arranged with shearing groove, the column foot plate of transmission tower is positioned at shearing groove, the horizontal shear that column foot plate is born is directly passed in the concrete around shearing groove, reduce the horizontal shear that stone bolt bears, improve the rate of utilization of strength of stone bolt, simultaneously, effectively prevent column foot plate from sliding, ensure that transmission tower safety is fixing.
The degree of depth of described shearing groove is not less than the thickness of described column foot plate, ensures that column foot plate is positioned at shearing groove, reduces horizontal shear to the impact of column foot plate, effectively strengthens the fixed effect of transmission tower.
Described shearing slot, in the end face central area on described basis, ensures that shearing groove surrounding has the concrete of same thickness, realizes the uniform stressed of shearing groove, improve shear strength, strengthen basic application life.
Also be provided with the distribution bar arranged around described shearing groove in described basis, be conducive to resisting larger transmission tower foundation active force.
Described stone bolt is multiple, and multiple described stone bolt is circumferentially evenly arranged around the center of described shearing groove, strengthens being fixedly connected with of column foot plate further, meanwhile, makes stone bolt uniform force, ensure its tensile strength.

Detailed description of the invention
Below embodiment of the present utility model is described in detail:
As shown in Figure 1, a kind of basis of transmission tower, is made up of concrete casting, and transmission tower 200 is fixed on basis 100.Transmission tower 200 is provided with column foot plate 210 near the one end on basis 100, basis 100 is arranged with the shearing groove 110 with column foot plate 210 form fit, at least one stone bolt 120 is embedded with in shearing groove 110, stone bolt 120 one end is embedded in the concrete below shearing groove 110, the other end stretches out the bottom of shearing groove 110, and column foot plate 210 is provided with the fixing hole coordinated with stone bolt 120.The utility model column foot plate 210 is fixed in shearing groove 110, the horizontal shear that column foot plate 210 is born is directly passed in the concrete around shearing groove 110, reduce the horizontal shear that stone bolt 120 bears, improve the rate of utilization of strength of stone bolt 120, simultaneously, effectively prevent column foot plate 210 from sliding, ensure that transmission tower 200 safety is fixing.
In the present embodiment, stone bolt 120 is multiple, and multiple stone bolt 120 is circumferentially evenly arranged around the center of shearing groove 110, strengthens being fixedly connected with of column foot plate 210 further, meanwhile, makes stone bolt 120 uniform force, ensure its tensile strength.
Basis 100 is provided with end face 130 near one end of transmission tower 200, shearing groove 110 is arranged at the central area of end face 130, ensures that shearing groove 110 surrounding has the concrete of same thickness, realizes the uniform stressed of shearing groove 110, improve shear strength, strengthen the application life on basis 100.The degree of depth of shearing groove 110 is preferably not less than the thickness of column foot plate 210, makes column foot plate 210 be positioned at shearing groove 110, reduces horizontal shear to the impact of column foot plate 210, effectively strengthens the fixed effect of transmission tower 200.
Also be provided with the distribution bar (accompanying drawing does not identify) arranged around shearing groove 110 in the concrete on basis 100, be conducive to resisting larger transmission tower foundation active force.
In sum, described in the utility model basic 100 utilize the side drag of shearing groove 110 to offset the horizontal shear suffered by stone bolt 120, improve the rate of utilization of strength of stone bolt 120, and effectively prevent column foot plate 210 from sliding, enhance the stability of transmission tower 200, ensure equipment use safety, meanwhile, its structure is simple and easy to realization, cost of manufacture is cheap.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this manual is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
