Steel member splicing pretensioner and method for connecting component elements with pretensioner

Abstract

The invention discloses a steel member splicing pretensioner which comprises a plate-shaped keel. The plate-shaped keel is longitudinally arranged. Rectangular arch grooves are formed in the lower portion of the plate-shaped keel. Fixing plates are horizontally clamped between the rectangular arch grooves of the plate-shaped keel. Two pairs of supporting side plates which are arranged upwards in an extending mode on the side faces of the plate-shaped keel on two side edges of the fixing plates are respectively and fixedly connected with two side faces of the plate-shaped keel. Rectangular through holes are defined by the upper surfaces of the fixing plates and two sides faces and the top faces of the rectangular arch grooves. Fixing through grooves are formed in the positions, corresponding to the rectangular through holes, of the fixing plates. The steel member splicing pretensioner has the advantages of being simple in structure, convenient to operate, strong in universality and capable of being used repeatedly. Meanwhile, the invention further provides a method for connecting component elements with the pretensioner, two thin elements (such as steel sheets) can be connected, and meanwhile the thicknesses and the directions of the component elements are not limited, and the problems of assembling, separating, lifting and the like of the component elements in a large steel structure equipment manufacturing industry are solved.

Description

technical field [0001] The invention relates to an auxiliary device for manufacturing and installing large-scale equipment, in particular to a splicing pretensioner for steel components, and also relates to a method for connecting subcomponents using the pretensioner. Background technique [0002] During the manufacture and installation of large-scale steel structure equipment, it is generally necessary to decompose the overall equipment into several sub-components to facilitate hoisting and transportation. After the sub-components are manufactured, the sub-components are assembled into a whole, and the relevant test data and functional parameters are obtained through debugging. When the equipment needs to be transported to other places, the overall equipment needs to be disassembled and transported in sub-component units. [0003] At present, temporary welding or bolt connection is generally used to solve the assembly of sub-components in the manufacture of large-scale ste...
