Device and method for permanently connecting and fixing arc plates

Abstract

The invention provides a device and method for permanently connecting and fixing arc plates. The device comprises a pair of U-shaped prefabricated arc plate end surfaces, wherein a pair of bottom plates is mounted at the bottom of the end surface of each prefabricated arc plate; the planes of the bottom plates are perpendicular to the plane of the end surface of the corresponding prefabricated arc plate, and half of each bottom plate is inserted and fixed in the end surface of the corresponding prefabricated arc plate; a small connecting plate is mounted at the upper part of the left end surface of the end surface of each prefabricated arc plate, and a large connecting plate which corresponds to the small connecting plate is mounted at the upper part of the right end surface of the prefabricated arc plate; each small connecting plate and the corresponding large connecting plate are connected through transverse beams, so that the corresponding left end surface and the corresponding right end surface are fixed; inclined beams are connected between each large connecting plate and the bottom plate of the corresponding end surface for fixing. According to the method, the device is adopted for connection and fixing. Through the adoption of the device and method, disclosed by the invention, the mounting quality of prefabricated arc plates can be improved, the mounting speed of prefabricated arc plates can be raised, and the input of per machine per team is reduced; besides, the fixing method of joints of the arc plates is simplified, so that the fixing method is convenient for on-site operation, and the high safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a permanent connection and fixing device and method for arch slabs used for butt joint installation of bridge prefabricated slabs. Background technique [0002] In the installation process of bridge prefabricated arch slabs, the positioning and fixing of prefabricated arch slab joints is one of the key processes. The most time-consuming, it is necessary to wait for the welding of the connecting steel bars at the end of the arch slab to be completed, and the concrete at that place reaches a certain strength before proceeding to the next process of construction. If the control is not good, it will easily cause quality hazards and safety accidents. And once quality and safety problems occur during the installation process, the post-processing is very difficult. [0003] At present, domestic prefabricated arch slabs are mostly connected by pre-embedded steel bar joints...

AI Technical Summary

Problems solved by technology

[0004]The installation efficiency of this process is low, there are many links, the cycle is long, the installation quality is greatly affected by factors such as time and environment, the molding quality is not easy to control, and there are certain safety hazards

During the installation of on-site prefabricated arch slabs, due to the insufficient support of the steel bars at the joints, the installation line of the arch slabs cannot be on the same arc, and even the settlement at the joints is uneven, causing the welded steel bars to be strained. , affecting the overall landscape effect of the arch bridge
