Fast and precise measuerement of couplings and similar components

In bridge building and on large projects, parts of the reinforcement often have to be connected with a coupler joint. To ensure that the reinforcement is placed in exactly the right position, the couplers must be checked for their exact position before concreting work.

On large projects with numerous couplers, this is a very time-consuming task for the surveyor. The measurements become even more complicated if the couplers do not protrude vertically from the floor, but rather laterally or at an angle from the wall.

With our adapters, these measurements can now be carried out quickly and precisely:

• For couplers that need to be measured laterally, two prisms are mounted on the adapters. First, the outer prism (gray in picture below center) is measured, followed by the second prism (red in picture), determining the direction to the coupler head (as in measuring by dual-prism offset). The centre of the coupler head is then determined by the specified height offset from prism two to the coupler head.
• When measuring vertical connections, one prism is sufficient, but in this case, we recommend our 220 degree prism RSMP480 so as not to lose contact with the station when turning the adapter.
