Universal reinforcing steel bar connecting assembly

Abstract

The invention relates to a universal reinforcing steel bar connecting assembly for connecting a first target reinforcing steel bar and a second target reinforcing steel bar. The universal reinforcingsteel bar connecting assembly comprises a first barrel, a connecting rod and a second barrel. The universal reinforcing steel bar connecting assembly is characterized in that one end of the connectingrod is spherically hinged to the first target barrel while the other end of the connecting rod is spherically hinged to the second barrel; a first connecting part connected to the first target reinforcing steel bar is detachably mounted in the first barrel, and a second connecting part connected to a second target reinforcing steel bar is detachably mounted in the second barrel. The universal reinforcing steel bar connecting assembly can connect two target reinforcing steel bars mechanically. Compared with an existing grouting bushing, the universal reinforcing steel bar connecting assembly is small in size, great in fault tolerance, reliable in connection and low in cost after batch production, can be widely applied to prefabricated shear walls, prefabricated columns, prefabricated beams, prefabricated floorslabs and the like, and can promote assembled buildings to take a giant step forward.

Description

technical field [0001] The invention relates to a universal steel bar connection assembly, which belongs to the technical field of prefabricated buildings. Background technique [0002] Industrialized prefabricated buildings are the general trend of the development of the construction industry, and the connection between the steel bars of adjacent prefabricated components has become a bottleneck restricting the further improvement of the prefabricated rate. One of the more recognized connectors at present is the grouting sleeve. Its invention and application have promoted the upgrading of prefabricated building technology from the fifth generation to the sixth generation. However, there are also some shortcomings in the grouting sleeve: [0003] 1. The fault tolerance range is small, generally only 5mm, that is, the steel bars corresponding to the two prefabricated components cannot be installed if the cumulative error is greater than 5mm. The cumulative error here include...

Problems solved by technology

This makes the hoisting of related prefabricated components very difficult, high cost and low efficiency

[0004] 2. Because a certain anchoring length must be met, the size of the grouting sleeve is relatively large, and it depends on high-strength grouting materials, which requires high material costs and high labor costs

Because of the high cost, it is currently mainly used in prefabricated shear walls and prefabricated columns, and in order to reduce the cost in the design, the spacing of the stressed longitudinal reinforcement is generally enlarged by 3 times (the spacing of the single side of the stressed longitudinal reinforcement is as high as 600mm), Unsatisfactory stress condition of the longitudinal reinforcement of the member
