Large diameter steel bar connecting sleeve

Abstract

The invention relates to a steel bar mechanical connection process in building construction, particularly to a large diameter steel bar connecting sleeve. The large diameter steel bar connecting sleeve comprises a connecting sleeve, a clamping piece and a fastening sleeve and is characterized in that the clamping piece is positioned at the internal side of the connecting sleeve; the fastening sleeve is positioned at the external side of the connecting sleeve; and the clamping piece and the connecting sleeve are wrapped inside the fastening sleeve. The large diameter steel bar connecting sleevecan connect two large diameter steel bars (above 16 diameters) coaxially and firmly and effectively bear and transfer the axial tension or the axial pressure of the two steel bars. In the case of thesteel bar mechanical connection process adopted at present, the invention can effectively reduce the equipment investment and save the occupied construction site and the labor force. Because the specialization and the social division of labor of product production are realized, the quality of products is reliable, working procedures are simple and rapid, and the construction progress can be accelerated.

Description

Technical field: [0001] The invention relates to a steel bar mechanical connection process in building construction, and relates to a large-diameter steel bar connection sleeve. technical background: [0002] At present, there are several types of steel bar mechanical connection (thick diameter) technology in my country's construction, such as steel bar sleeve extrusion connection, steel bar taper thread sleeve connection, steel bar upsetting straight thread sleeve connection, steel bar rolling straight thread sleeve connection, etc. Compared with welding connection, the mechanical connection of steel bars not only saves a lot of steel, but also saves auxiliary materials such as electric energy and solder. However, the above-mentioned types of mechanical connection processes have common shortcomings, that is, special steel processing equipment is required. , and need to occupy limited construction site land, need to be equipped with a certain number of operators for processing...

Problems solved by technology

[0002] At present, there are several types of steel bar mechanical connection (thick diameter) technology in my country's construction, such as steel bar sleeve extrusion connection, steel bar taper thread sleeve connection, steel bar upsetting straight thread sleeve connection, steel bar rolling straight thread sleeve connection, etc. Compared with welding connection, the mechanical connection of steel bars not only saves a lot of steel, but also saves auxiliary materials such as electric energy and solder. However, the above-mentioned types of mechanical connection processes have common shortcomings, that is, special steel processing equipment is required. , and need to occupy limited construction site land, need to be equipped with a certain number of operators for processing, and because the processing quality is not stable, it is also necessary to be equipped with special quality inspection personnel for inspection. At the same time, the processing progress of steel bars directly affects the next process. It even affects the construction progress of the entire project, not only wastes resources, but also the quality and progress of the construction cannot be well guaranteed
