Abstract
A foundation bolt eccentric connecting structure of a power transmission line iron tower foundation comprises foundation bolt bars located in a foundation main post. The foundation bolt bars are connected through foundation bolt stirrups. Foundation bolts fix a tower foot plate on the top surface of the foundation main post through a base plate, the outer sides of the foundation bolts are covered with a protecting cap, the center of a foundation bolt group and the enter of the top surface of the foundation main post do not coincide, anchoring short ribs are welded to the inner side of the lower end of every foundation bolt bar, and the upper portions of the two foundation bolt bars in the diagonal direction of an iron tower are in sleeved connection together through a foundation bolt pulling rib. The anchoring short ribs are welded to one side of the lower end of every foundation bolt; after the short ribs are placed towards the inner side of the foundation bolt group, space occupied by traditional anchoring parts at the lower ends can be saved and serve as a newly increased deviation value, four corners of the tower foot plate are subjected to corner cutting, the round protecting cap is used, the interval between the protecting cap and the edge of the foundation main post becomes large, and an increased value of the interval between the protecting cap and the edge of the foundation main post is the newly increased deviation value. The limit offset of the foundation bolt group is increased on the premise that the size of an original main post is kept unchanged.
Description
Technical field
The present invention relates to a kind of eccentric pattern that connects of stone bolt of power transmission line iron tower foundation.
Background technology
As shown in Fig. 1-3, when power transmission line iron tower foundation adopts stone bolt to connect, traditional approach is all that stone bolt group is placed in to basic principal post center, i.e. stone bolt group center and basic principal post center superposition.In recent years, along with the development of technology, iron tower foundation starts to adopt the eccentric connection of stone bolt gradually.
As shown in Fig. 4-6, be connected and compare with traditional Di Luo center, stone bolt group center departs from basic central point along steel tower diagonal, is equivalent to vertical and applies a reverse bending moment at basic capital, and offset by the level of active force is on basic impact to a certain extent.Appear compared with large and class basis and bored concrete pile foundation are dug in less the drawing of principal post sectional dimension for some principal posts, horizontal force generally plays the effect of controlling key dimension, adopts this kind of mode, can effectively reduce key dimension, can not increase difficulty of construction, there is considerable economic and social profit simultaneously.
Existing iron tower foundation adopts when stone bolt is eccentric to be connected; because conventional tower sole and protective cap are generally square; its diagonal is identical with steel tower and stone bolt group's diagonal; therefore; when eccentric placement, stone bolt group and column foot plate, protective cap are all along the skew of steel tower diagonal, and its critical distance that can be offset is generally subject to the control of the factor such as stone bolt bar and the interior stirrup distance of basic principal post, foot bolt fastening end and the main muscle distance of basic principal post, protective cap and basic principal post Edge Distance.
For saving base concrete amount, when basic engineering, all reduce as far as possible foundation main column dimension, therefore, be subject to the impact of above-mentioned governing factor, hour, the actual distance that can be offset of stone bolt group is also smaller, is difficult to bring into play the advantage of stone bolt group bias for foundation main column dimension.Increase ground spiral shell eccentricity value if want, need to strengthen foundation main column dimension, but increasing principal post size certainly will cause the increase of base concrete amount, produces waste.
Summary of the invention
The object of this invention is to provide a kind of when foundation main column dimension hour, keeping, under the prerequisite of original principal post size constancy, further increasing the connection pattern of stone bolt group limit side-play amount.
For achieving the above object, the present invention is by the following technical solutions:
A stone bolt eccentric connecting structure for power transmission line iron tower foundation, it comprises the stone bolt bar that is positioned at basic principal post, between stone bolt bar, fixes with stone bolt stirrup; Described stone bolt is fixed on foundation main capital face by backing plate by column foot plate, and the outside of stone bolt covers with protective cap; Described stone bolt group center does not overlap with foundation main capital face center, the short muscle of inner side, each stone bolt bar lower end welding anchoring; Two stone bolt bar tops along steel tower diagonal connect together by stone bolt lacing wire.
Described column foot plate is rectangle, and carries out corner cut at rectangle four jiaos; Described protective cap is circular protective cap.
Described stone bolt lacing wire is S type or O type.
Adopt the present invention of technique scheme, stone bolt lower end one side is welded short muscle anchoring, and after short muscle is placed towards stone bolt group inner side, tradition anchoring piece shared space in lower end can be saved out, as newly-increased deviant; Four jiaos of column foot plates carried out corner cut and use circular protective cap, make the spacing at protective cap and basic principal post edge become large, being newly-increased deviant apart from increase value between the two.The present invention is keeping under the prerequisite of original principal post size constancy, increases stone bolt group limit side-play amount, meanwhile, does not substantially increase difficulty of construction, has considerable economic and social profit.

Detailed description of the invention
As shown in Fig. 7-9, basis principal post 1 should be made up of stirrup 10, the outer stirrup of principal post and concrete in the main muscle 9 of principal post, principal post, at the interior stone bolt bar 6 that arranges of basic principal post 1, stone bolt bar 6 is generally four, and fixing with stone bolt stirrup 7 between stone bolt bar 6, the quantity of stone bolt stirrup 7 is depending on the length of stone bolt bar 6.Stone bolt 2 is fixed on basic principal post 1 end face by backing plate 3 by column foot plate 5, and the outside of stone bolt 2 covers with protective cap 4.
In the present invention, stone bolt group center does not overlap with basic principal post 1 end face center, i.e. eccentric connection.For increasing stone bolt group's limit side-play amount, at the short muscle 12 of each stone bolt bar 6 inner side, lower end welding anchoring, space shared traditional anchoring piece can be saved out like this, as newly-increased side-play amount., connect together by stone bolt lacing wire 11 along two stone bolt bar 6 tops of steel tower diagonal, stone bolt lacing wire 11 can be S type or O type meanwhile.
In addition, in the present invention, column foot plate 5 is rectangle, and carries out corner cut at rectangle four jiaos; And protective cap 4 is circular protective cap.Make like this protective cap 4 and the spacing at basic principal post 1 edge increase, be newly-increased offset value delta apart from increase value between the two.
