Abstract
The utility model discloses an anchoring component in the base of an inclined pylon. The anchoring component comprises a concrete soleplate that is provided with a bottom surface and a top surface; the anchoring component is fixed in the soleplate and is arranged in an inclined way corresponding to the bottom surface; the inclination angle of the anchoring component and the inclination angle of the feet of the pylon are similarly identical or identical; the lower end of the anchoring component is fixedly provided with at least one layer of transverse frames; one side of the transverse frames is fixedly connected with the anchoring component, and the other side is inserted in the base of the pylon. The anchoring component adopts a structure of an angle-clip type anchor, and has the beneficial effects of simple structure and low costs. After the anchoring component is used for a long time, the anchoring effects are reliable and the stability of the base of the pylon can be further improved in the long-term use.
Description
Technical field
The utility model relates to electric power transmission ﹠ distribution field, relates in particular to a kind of anchoring piece that is applied to batter post formula iron tower foundation.
Background technology
Iron tower foundation is the common infrastructure of electric power transportation art, considers for economy, adopts the straight column type iron tower foundation of shallow embedding mostly in the past.
Iron tower mostly is up-narrow and down-wide positive ladder type greatly.As shown in Figure 1, the column foot 2 of iron tower generally is fixed on the right cylinder 1 in the inclination mode.For increasing the bonding strength of right cylinder 1 and column foot 2, general meeting pre-buried a plurality of foundation bolts 11 in concrete right cylinder 1.
But because foundation bolt 11 be metal material, different with the coefficient of thermal expansion of the right cylinder 1 of concrete material, so service time long after, can the generation slit between foundation bolt 11 and the right cylinder 1.Because the existence in this slit, all in theory foundation bolts 11 can move to a direction, thereby make the whole iron tower that is fixed on the foundation bolt 11 produce lateral displacement, reduce the connective stability and the overturning or slip resistance analysis performance of iron tower foundation.
Therefore, those skilled in the art is devoted to research and develop the good anchoring piece that is used for iron tower foundation of a kind of stability in use simple in structure, long-term for a long time always.
The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides the anchoring piece in a kind of simple in structure, cost is low, long-term stability in use is good batter post formula iron tower foundation.
For achieving the above object, the utility model provides the anchoring piece in a kind of batter post formula iron tower foundation, comprise concrete sole plate, described sole plate has a bottom surface and an end face, be set with anchoring piece in the described sole plate, the described relatively bottom surface of described anchoring piece is obliquely installed, and the angle of inclination of described anchoring piece is roughly the same or identical with the angle of inclination of iron tower column foot, and described anchoring piece lower end is set with one deck lateral frame at least; Fixedly connected with described anchoring piece in one side of described lateral frame, the another side of described lateral frame is plugged in the described iron tower foundation.
Preferably, described anchoring piece by the welding of a plurality of angle steel make and form can ccontaining iron tower column foot hollow hub.
Preferably, described anchoring piece and described lateral frame is fixedly connected as welding.
Especially, can adopt with iron tower column foot same specification angle steel and make anchoring piece, be plugged in the iron tower foundation, be connected to one with the form that the cornerite steel is connected, to obtain more firm connection effect with iron tower column foot master material.
According to the size of upper load, the lateral frame of single or multiple lift angle cleat can be set on anchoring piece.
Anchoring piece of the present utility model has adopted the technical scheme of angle cleat anchoring, and the lateral frame of welding angle cleat on the anchoring piece of oblique cutting is one side make being plugged in the concrete foundation of lateral frame angle cleat.
After using the long period, though between the iron tower foundation of anchoring piece that metal material makes and concrete material, also can produce because the slit that coefficient of expansion difference causes.But because the deadweight that anchoring piece is bearing iron tower, the anchoring piece that this deadweight is obliquely installed to lower compression, one side of the lateral frame angle cleat that is plugged in the concrete foundation is squeezed on the concrete foundation, between the two above-mentioned gap space is disappeared and can't relative displacement, anchoring effect is reliable, thereby has improved the stability of iron tower foundation in long-term the use.
And the utility model reduced the influence of the horizontal component that may cause the concrete division, so the steel quantity consumption of anchoring piece is also lower, has reduced the manufacturing cost of batter post formula iron tower foundation integral body owing to made full use of the withstand voltage characteristic of concrete.
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the structural representation of the pillar iron tower foundation in the prior art;
Fig. 2 is the structural scheme of mechanism of the utility model one specific embodiment;
Fig. 3 is an A-A cross-sectional schematic among Fig. 2.
The specific embodiment
Be a specific embodiment of anchoring piece of the present utility model as shown in Figure 2, batter post formula iron tower foundation 1 comprises the concrete foundation base plate with a bottom surface and an end face, anchoring piece 2 relative bottom surfaces are obliquely installed in sole plate 1, and anchoring piece 2 lower ends are set with two-layer lateral frame 21.Anchoring piece 2 and lateral frame 21 make for being angle cleat, and one side of lateral frame 21 is connected to one with anchoring piece 2, and the another side of lateral frame 21 is plugged in the concrete of iron tower foundation 1.
In the present embodiment, anchoring piece 2 is made by the welding of a plurality of angle steel, and form can ccontaining iron tower column foot hollow hub.Employing makes anchoring piece 2 with the angle steel of iron tower column foot same specification, is illustrated in figure 3 as its cross sectional representation, is plugged in the iron tower foundation 1, is connected to one with the form that the cornerite steel is connected with iron tower column foot master material, to obtain more firm connection effect.
After using the long period, also can form the slit between anchoring piece that metal material makes and the iron tower foundation of concrete material 1 because of the coefficient of expansion is different.But because the deadweight that anchoring piece 2 is bearing iron tower, the anchoring piece 2 that is obliquely installed in this deadweight to lower compression, one side of lateral frame 21 angle cleats that are plugged in the iron tower foundation 1 is squeezed on the concrete iron tower foundation 1, between the two above-mentioned gap space is disappeared and can't relative displacement, because concrete has good voltage endurance, the anchoring effect of whole iron tower foundation 1 is reliable, thereby has improved the stability of iron tower foundation 1 in long-term the use.
In other specific embodiments,, the lateral frame of single or multiple lift angle cleat can be set on anchoring piece according to the difference of upper load size.
In sum, described in this manual is several preferred embodiment of the present utility model, and above embodiment is only unrestricted in order to the explanation the technical solution of the utility model.All technician in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within claim protection domain of the present utility model.
