Problems solved by technology

[0005] In view of the above problems, at present domestic and foreign in the field have developed targeted connection joints such as steel grouting sleeves, but, the present prior art The cost of the steel grouting sleeve joint is still high, and if it is applied to the connection of horizontal steel bars, the length requirements for the steel bar joints are still relatively long, and the applicability in actual construction projects is still relatively poor
[0006] In view of the existence of the above problems, a new, widely applicable and relatively low cost can be conveniently and effectively connected two steel bars that are difficult to rotate freely but can be connected It is imperative to invent the invention of steel bars that are too short to meet the requirements of steel bar lap joints, where the steel bar joints are located in a small space and cannot be welded, or with a large welding workload.

Abstract

The invention provides standardized complete equipment for mechanical connection of reinforcing steel bars. The equipment comprises a first component and a second component which are connected, and further comprises a third component for connecting the first component and the second component, wherein the first component or the second component is mechanically connected to two ends of the third component. The technical scheme of the invention is a new invention technology which is wide in applicability, relatively low in cost and capable of conveniently and effectively connecting two building accessories which are difficult to rotate freely, short in connectable length of the steel bars and cannot meet the lap joint requirement of the steel bars, small in space where a steel bar joint is located and cannot adopt a welding form or are large in welding workload.

Description

technical field [0001] The invention relates to a standardized complete set of steel bar mechanical connection standardization equipment for building components in the field of civil engineering, and more specifically relates to a steel bar mechanical connection joint when the connected steel bar is difficult to rotate freely. Background technique [0002] In the civil engineering field of the existing technology, the steel bar engineering is the basic skeleton of the building structure, and the connection method and connection measures of the steel bar are the key technologies in the civil engineering. [0003] At present, the main methods of steel bar connection in this field include steel bar binding connection, steel bar welding, steel bar mechanical connection, etc. Of course, different steel bar connection methods are applicable to certain specific environmental conditions of engineering construction. [0004] For some engineering construction conditions, if the two st...
