Abstract
The invention relates to a transverse fastening type female and male flange device. The transverse fastening type female and male flange device comprises a female sleeve and a male sleeve of the flange device. The lower end of a cylinder of a tower body upper section serves as an outer ring of the female sleeve. A female sleeve auxiliary gasket is welded into the cylinder. A female sleeve inner ring is welded to the auxiliary gasket to form a reverse U shape. A male sleeve circular ring is welded into an upper cylinder of a tower body lower section and extends into the upper portion of the female sleeve after being matched with the upper portion of the female sleeve, and the male sleeve circular ring and the upper portion of the female sleeve are fastened and connected through transverse high-strength pin shaft bolts. The sections of a single-pipe tower body are installed and connected into a whole through the method. A conventional flange connection method is broken through, and safety and reliability are achieved.
Description
Technical field
Original post and telecommunications steel tower, its form of structure has trussed construction, the self-supporting steel tower of the single tube structure composition of box and Guywire tower, with regard to the single-pipe tower of box, because tower body height is higher, for convenience of transport and installation, generally be divided into multiple sections to carry out high-altitude to scene and splicing single tube steel tower is installed, sections connects the general outward flange that adopts and connects, for the purpose of good looking appearance, inner flange is generally adopted to be connected with cover joint formula at present, namely outward appearance looks and only stays about one connecting sewing, flange bolt is in cylindrical shell, personnel are climbed up by cat ladder in cylindrical shell and tighten high-strength bolt at inwall.Epimere tower body lower end is enclosed within hypomere tower body upper end by cover joint formula, and its socket length must be greater than the 1.5d(d--junction tower body diameter of junction diameter) more than, and not resistance to vertical earthquake.Along with the development of post and telecommunications cause, single-pipe tower height progressively drops to 30 ~ 35m, and tower body diameter drops to 600 ~ 300mm, and when adopting inner flange tower section to connect, personnel at tower in-vivo procedures, even if the inner flange that higher tower body adopts, cannot also manufacture complicated cost high.
Summary of the invention
The object of the invention is to provide a kind of horizontal fastening-type concave-convex flange device, off the beaten track Flange joint is flange is fluctuating plate, it is concavo-convex inner-outer sleeve that the upper and lower perpendicular fastener of high-strength bolt changes flange into, high-strength bolt changes shear-pin axle bolt into, shearing resistance can tighten again the concavo-convex inner-outer sleeve frictional force of flange is worked, and flange inner sleeve fluting, both ensured that flange inner-outer sleeve was adjacent to, reach frictional high-strength bolts and pay anastomosis, reaching again flange is that concavo-convex cover joint formula becomes double shear stress, ensures to be perfectly safe reliably.
To achieve the above object of the invention, technical scheme of the present invention is:
A kind of horizontal fastening-type concave-convex flange device, comprise the recessed cover of flange apparatus and convex cover, recessed cover as the outer shroud of recessed cover, is welded with a recessed cover sub-gasket by the lower end of tower body epimere cylindrical shell in cylindrical shell, sub-gasket to be burn-on recessed cover inner ring, formed and fall " recessed " shape; In the cylindrical shell of tower body hypomere upper end, be welded with a convex cover annulus, with top recessed overlap coordinate after put in the recessed cover in top, and carry out being fastenedly connected by the method the single-pipe tower tower body of segmentation being installed with horizontal high-strength pin bolt and connect into entirety.
2 times, edge d(d-high-strength pin diameter is left at concavo-convex cover) place, be drilled with high-strength bearing pin screw, in addition fastening with high-strength pin bolt.
Fit tightly in order to ensure recessed cover flange, reach high-strength bolt and connect the frictional connection paid and require, in recessed cover inner ring, each high-strength bolt interval has shrinkage joint, and this shrinkage joint, by tightening laterally high-strength pin bolt, reaches the object that concavo-convex cover inside and outside wall fits tightly.Laterally its Main Function of high-strength pin bolt bears the tower body epimere shearing that drawing causes under wind-force effect, and when high-strength bolt is tightened, the recessed cover of tower body concave-convex flange and the convex cover of concave-convex flange are fitted tightly.
In order to reach the comprehensive shearing resistance of high-strength pin bolt, the high-strength nut front end that recessed cover inner ring is burn-on is provided with an adjustment space.
Laterally high-strength pin bolt adopts Materials with High Strength and in addition heat treatment, makes its shear strength reach >=tower body mother metal more than 2 times.Simultaneously in order to ensure that the bearing pin part of high-strength pin bolt contacts (reaching double shear stressed) completely with recessed cover inner ring, leave a transition rings being welded in the nut front end in recessed cover inner ring, stressed to ensure high-strength pin bolt double shear.
This connection tower body barrel place exposes and has that the slim round end of a high-strength bolt is thick about has about 8mm.Comparatively the connection of cover joint exceeds tower body more than a wall thickness >10mm, slightly attractive in appearance, as complete hidden linkage will be made, can by the thickness of concavo-convex cover toward the high-strength pin bolt round end of indentation one in tower body cylindrical shell, the thin plate case of external application 0.3mm covers.
In order to aesthetic function, sheathing can also be provided with outside the high-strength pin bolt of described transverse direction.Specifically, as entirely hidden in concave-convex flange junction will be reached, by the thickness of concave-convex flange inner and outer ring to the high-strength pin bolt round end of indentation in tower body one, on external application 0.3mm thin plate case cover, concave-convex flange can be connected and reaches entirely hidden.
Compared with prior art, the present invention:
(1) utilize the material of tower body cylindrical shell self to add epirelief cover annulus and recessed cover inner ring, tower body splicing Flange joint can be completed.Save tunica joint mechanism tower body epimere and need pack into tower body hypomere >=1.5d(d--junction tower body diameter) code requirement.About save 2/3 of tower body cover material-saving material.
(2) the present invention adopts horizontal fastening type flange device, and personnel can carry out at the outer laterally fastening high-strength bolt of tower body a kind of New concave-convex flange connecting apparatus that tower body saves connection up and down.It is characterized in that having a whole set of Flange joint and fastening structure to guarantee to connect and fastening reliability and safety according to horizontal fastening-type concave-convex flange device.
