For example, as shown in fig. 1 to 2, the first segment 1 and the second segment 2 are connected by a temporary connection structure 3 (flange) provided with a bracket 31, and the flanges of the two segments are connected by bolts 4 and welded by a permanent weld 5 after the anchor cable is installed.
However, practical application finds that the flange structure adopted at present has some defects, firstly, the number of bolts on the flange is too large, and the bolts are arranged in the steel pipe, so that the alignment and the bolt installation during the hoisting of the overhead cable are not facilitated, and particularly, when the wind power of overhead operation is large, the steel pipe is particularly difficult to align and install, so that the construction risk of the overhead operation is increased; secondly, the structure of the inner flange plate inside the steel pipe is complex, the inner space of the steel pipe is occupied greatly, and when concrete is injected into the pipe in the later stage, the compactness of the concrete at the position has problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: aiming at the problems of more bolts of the traditional flange plate, difficult alignment and incompact pressure injection of concrete in the pipe in the prior art, the temporary connection structure of the steel pipe arch ring segments is provided.
In order to realize the purpose, the utility model discloses a technical scheme be:
the utility model provides a steel pipe arch ring section temporary connection structure, includes a plurality of otic placodes that are located the arch ring section outside, all the otic placode along the circumference interval of arch ring section sets up, just the otic placode with the steel pipe outer wall fixed connection of arch ring section the otic placode with still be connected with a plurality of brackets, adjacent two between the otic placode of arch ring section is connected through the bolt.
Temporary connection structure, including otic placode and bracket, the rethread bolt is connected, otic placode and bracket all set up the steel pipe outer wall at the arch ring festival section, do not influence steel pipe inner structure, therefore do not have any influence to the flow of concrete when intraductal concrete pressure is annotated, have guaranteed the closely knit nature of intraductal concrete. Simultaneously, all otic placodes set up along the circumference interval of hunch circle segment, the installation work load of connecting bolt that has significantly reduced, and the otic placode is arranged in the outside of steel pipe, is convenient for more counterpoint installation operation, has shortened high altitude construction time, has reduced the construction risk. In addition, after the permanent welding seam welding of two adjacent arch ring sections is completed, the temporary connection structure can be directly cut off, and steel can be recycled, so that the energy conservation and the environmental protection are facilitated.
As a preferred embodiment of the present invention, all of the ear plates are arranged along the circumferential symmetry of the arch ring segment.
As the utility model discloses a preferred scheme, every the symmetry is equipped with a plurality ofly on the otic placode the bracket.
As the preferred scheme of the utility model, the otic placode the bracket respectively with steel pipe outer wall welded connection.
As the preferred scheme of the utility model, the otic placode the bracket is the steel sheet.
As the utility model discloses an optimal scheme, along the circumference symmetrical welding of hunch circle segment has 4 the otic placode, every the otic placode all is through 3 the bracket with the steel pipe outer wall is connected, and every all be equipped with 2 bolt holes on the otic placode to through bolted connection adjacent two the hunch circle segment.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
temporary connection structure, including otic placode and bracket, the rethread bolt is connected, otic placode and bracket all set up the steel pipe outer wall at the arch ring festival section, do not influence steel pipe inner structure, therefore do not have any influence to the flow of concrete when intraductal concrete pressure is annotated, have guaranteed the closely knit nature of intraductal concrete. Simultaneously, all otic placodes set up along the circumference interval of hunch circle segment, the installation work load of connecting bolt that has significantly reduced, and the otic placode is arranged in the outside of steel pipe, is convenient for more counterpoint installation operation, has shortened high altitude construction time, has reduced the construction risk. In addition, after the permanent welding seam welding of two adjacent arch ring sections is completed, the temporary connection structure can be directly cut off, and steel can be recycled, so that the energy conservation and the environmental protection are facilitated.
