STR Coupler

This coupler with two different sizes on the coupler connects rebars with different sizes.SAHAND produces the couplers according to the customer needs but STR coupler is always available if difference of diameter of rebars is only one step in their sizes . SAHAND produce couplers from 20 to50mm .The solid round steel DIN 1.1191 is used for the couplers. Universal and CNC machines are used to produce the couplers.

Description

STR coupler | Transition coupler

Reinforced concrete design and construction has historically focused on the use of lap joints as a method of load transfer between reinforcing bars. Connecting the cover of reinforcement is not the most suitable method for connection, in many cases and situations, using mechanical rebar connections is more convenient from the design point of view and more desirable from the construction point of view

Rebar coupler systems, also known as mechanical connectors, are used as an alternative to lap joints in concrete. These connections transfer the load on the rebar directly from one rebar to another without relying on the concrete bond and concrete conditions around the rebar

Now that we are familiar with the philosophy of the coupler, we should know that there are cases in which two rebars of two different sizes meet at the same point and must be connected to each other to form a single rebar. In these cases, the coupler that is used to connect these two rebars is different from the normal rebar, in fact, this coupler has two different thread sizes on its sides and can provide the possibility of connecting two rebars with different diameters on both sides
