Detailed description of the invention
Illustrating embodiments of the invention below in conjunction with the accompanying drawings, embodiment is not construed as limiting the invention:
A kind of easy steel pipe arch bridge arch rib closure device, it is characterized in that, comprise string pipe, the position of two string pipe docking is docking sleeve pipe, comprising in docking sleeve pipe and spend blue nut, spend blue nut inner wall to comprise screw thread, also comprise that spiral accesses the both sides spent in blue nut spends blue screw rod, the blue screw rod of spending of both sides each connects a backing plate, and backing plate chord pipe connects.Technique effect and the process that realizes thereof of the essence that the technical scheme at this place is played are as follows: rotate and spend blue nut, drives two spend blue screw rod close to or far away from, convenient dock.
Described backing plate avris comprises locating slot, spends blue screw rod through location steel tank, location steel tank also comprises and spends blue bolt spacing hole.Described backing plate connects floor.Described floor comprises more than a piece of, and a piece of above floor is respectively positioned on inside string pipe around floor central distribution, floor and backing plate.Internal lining pipe is also comprised between described floor.Described floor is welded to connect the inwall of string pipe.
More specifically realize process as follows:
Main arch steel pipe about when steel pipe arch bridge closure connects, main arch steel pipe i.e. string pipe, it is respectively provided with in main arch steel pipe and is evenly arranged eight pieces of ribs for base and backing plate, it is provided with location steel tank connection, steel tank horizontally arranged limited location hole, location and backing plate before backing plate to be connected by bolt with location steel tank and be connected, instantaneous closure is configured to spend blue bolt, spends blue bolt to include bolt and positions, with being provided with on screw rod, screw rod, the spacing hole that steel tank is identical.The operation principle spending blue bolt is: spending blue nut to be fabricated to reverse thread, rotating and spending blue nut is that blue screw rod into or out simultaneously is spent in both sides.
Closing construction job content is as follows: rib for base is welded in before sections installation steel pipe arch bridge inwall in advance, after completing the installation of left and right sides main arch sections, install to put in place and adjust its position by location steel tank on left and right sides backing plate and be up to the standard, treat environment temperature, after arch rib absolute altitude reaches closure condition, instantaneous closure structure is installed, the nut spending blue bolt is loaded in the steel tank of location with screw rod, and adjust the spacing hole position spending blue screw rod, the spacing hole making location steel tank and Hua Lan screw rod is in same position and limits its rotation with wearing pin, rotary flower orchid nut makes both sides arch rib hold out against simultaneously, complete instantaneous closure；Having captured that the operation of existing steel pipe arch bridge closing construction is complicated, closure operation elapsed time is longer, safety coefficient is relatively low and closes up precision and the problem of main arch Stress non-homogeneity.
Present configuration design is simple, rationally, constructing operation is convenient, the instantaneous closing construction completing steel pipe arch bridge that can be time saving and energy saving, and join the two sections of a bridge, etc precision and stress of arch costal can preferably be adjusted, reduce the security risk of long-time work high above the ground, there is reasonable in design, the advantage that simple to operate and construction cost is low.
Adjusting the main arch lifting sections of the left and right sides, in advance rib for base and base are welded on left and right sides rib-lifting section, the rib for base of welding is evenly arranged on supervisor's inwall, and the center internal lining pipe in rib for base is fixed.During environment temperature and arch rib Pass line adjustment, installing location steel tank, the angle of regulation location steel is close to vertically.Under the conditions of suitable closure, blue bolt will be spent to put into location steel tank, both sides spend blue screw rod and the spacing hole positioning steel tank to fix spacing with wearing pin, spend blue nut to make both sides arch rib hold out against under instantaneous closure constructs in the middle of regulation.
In specific implementation process: steel tube arch rib uses non-support cable crane system system to install, the most symmetrical free cantilever erection in two sides, stayed knotting method installation, arch rib reserves closure section in vault span centre portion；After both sides main arch rib is installed to closure section, adjust arch rib integral linear, adjust the length spending blue bolt according to the distance of location, the both sides steel tank of closure condition, and carry out the instantaneous closure of installation.
The mouth of pipe of Guan Zhongyi string pipe of said two string comprises apron, and apron comprises apron periphery, and the when of two string pipe docking, apron can be extruded.Technique effect and the process that realizes thereof of the essence that the technical scheme at this place is played are as follows: can extrude at the apron of two string pipes when of extruding, it is possible to form waterproof structure, it is to avoid water flows between two string pipes.
The mouth of pipe of Guan Zhongyi string pipe of said two string comprises extruding plate, and extruding plate is round and can push down apron periphery.Technique effect and the process that realizes thereof of the essence that the technical scheme at this place is played are as follows: extruding plate is round and can push down apron periphery, therefore, it is possible to cover sealing, it is possible to the position water inlet avoided contact with, and then affect sealing.
The each self-contained inclined wall of part of said two string pipe docking.Technique effect and the process that realizes thereof of the essence that the technical scheme at this place is played are as follows: inclined wall can water guide, be avoided that water is entered to interface position.
In a creative way, each effect above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
The technique effect that above structure realizes realizes clear, and discounting for additional technical scheme, this patent title can also is that a kind of closure structure.Part details not shown in figure.
It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, the most mutually restrict, but it can also be mutually combined in the case of not conflicting, reach multiple effect and jointly realize.
The general principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Those skilled in the art is it should be recognized that the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within claimed scope.
