Technical field

This application involves field of bridge construction, in particular to a kind of arch rib closure construction method and rib structure.

Background technique

In arch rib work progress, the lifting of arch rib closure section (the arch rib segmentation finally set up) is particularly important, and one As when constructing, arch rib closure section component is sent to corresponding position by loop wheel machine, after adjusting, is fixed temporarily in surrounding using code plate Afterwards, then by after the main weldering seam welding of part, loop wheel machine can loose hook, complete the installation of arch rib closure section.

In current work progress, the weight of arch rib closure section is almost transmitted on underlying holder, to falsework Requirement for bearing capacity is very high；It further needs exist for after welding main weld part, loop wheel machine could break off relations, and can postpone to actually accomplish operation Time.

Summary of the invention

The embodiment of the present application is designed to provide a kind of arch rib closure construction method.It is intended to improve existing arch rib and closes The big problem of the bearing capacity of falsework below when imperial.

The application first aspect provides a kind of arch rib closure construction method, for by the opposite first end of closure section, second End is connected with the segmentation of the first arch rib, the segmentation of the second arch rib respectively；Arch rib closure construction method mainly comprises the steps that

In closure section first end end face, at least three first connectors, opposite second end end face setting at least three are set Second connector；At least two at least three first connectors are located at the opposite two sides in first end end face；At least three At least two in a second connector are located at the opposite two sides in second end end face.

End face setting and the one-to-one third connector of the first connector in the segmentation of the first arch rib, in the second arch rib point End face setting and one-to-one 4th connector of the second connector of section.

Closure section is lifted to predeterminated position, connects the first connector and third connector；Connect the second connector and the 4th Connector.Keep closure section, the segmentation of the first arch rib and the segmentation of the second arch rib relatively fixed.

The weld seam of closure section, the segmentation of the first arch rib and the segmentation of the second arch rib is welded again.

By the setting of the first connector, the second connector, third connector and the 4th connector, closure can be shortened The Connection Time that section, the segmentation of the first arch rib and the second arch rib are segmented.By the first connector of connection and third connector, and Connect third connector and the second connector, can make before welding the weight load of closure section along arch be transferred to positioned at its two The segmentation of first arch rib and the segmentation of the second arch rib at end.It is further transferred at arch springing, reduces the load-bearing of lower part falsework, mention The safety of height construction.

In some embodiments of the application first aspect, two at least three first connectors are located at first The two sides for holding end face opposite；At least one remaining first connector is located at the upper end of first end end face.

Two at least three second connectors are located at the opposite two sides in second end end face；It is remaining at least one the Two connectors are located at the upper end of second end end face.
