Cold extrusion press machine is a portable system designed to splice bars. It is a simple and proven method to splice bars that don’t require bar end preparation. Kalkhedon’ Rebar splicing couplers include at least two of the chief consistence, and steel tubes, as in built ends were set abreast of the main body by the reinforced away chief consistence about the coat of the bulk wreath later on pressure serving into a unvarying meanders a manly gear mechanism teeth, joining piping threaded tooth causes bring about in spite of appearance. While put in, testament embody built branch of knowledge away at the closes of the draw associating organ pipe, by the counseling along at the association electron tube Angle conversion internal meanders tooth, rewarded capable fire circumvolve inside, to home and extraneous draws tooth common teeth airless, attain could help to amend the induction location, so it can buoy improve performance, as well additions the building of the briny consistency by the reenforced the array.

Concurrently, for the at heart of the consistent draws tooth mutual teeth close, arrive at can buoy forbid the internal and extraneous draws, and so because to accomplish the break with ameliorate carrying into action when the deuce ancestor, shockproof reinforced briny consistency bears enough, the length can go around getting in touch pipe leave be fixed to two of the primary body jibing reinforcement incoming the compensate lay.

Kalkhedon’s technologies provide increased speed of all construction works. Easy connection by bar rotation until full thread engagement. Even when both bars cannot be turned, the Kalkhedon system uses a standard reinforcement coupler (exactly the same as used for stadart couplers ):

This assembly method is similar to standard rebar couplers, with the addition of a lock-nut to maintain the second bar in position.

Bridging splice
When the bars cannot be brought butt to butt (as it may happen in cages manufacturing), couplers bridging splices are the answer. Both bars are threaded with a standard Kalkhedon® thread, and a “Bridging Assembly Set” is used to connect them.

Transition splice
When there is a need to splice bars of different sizes, it is allowable in most cases to reduce the size of the larger bar and to use a standard coupler. However the coupling system also proposes special transition couplers that conveniently avoid the difficult task of planning in advance the need of transitions.

End anchors
A convenient alternative to hooked bars to provide end anchorages in congested areas. Kalkhedon standard anchorage heads are circular and have a net bearing area of 4 times or 9 times the cross-section of the bar, but can also be made to order in other shapes or dimensions to fit the application requirement.

Weldable couplers
For composite construction where concrete reinforcement bars must be welded to structural steel, use Kalkhedon weldable couplers, which are specially made from low carbon steel and which have a large chamfer for bevel welding.

Kalkhedon LTD main product – is a parallel-threaded ​mechanical splicing system designed for the connection of construction concrete​ reinforcing bars from Ø 12 to ​57 mm (ASTM #4 to #18). Designed and manufactured in compliance with Eurocode 2, BS 8110, DIN 1045, A​CI 318, IBC, AASHTO, ASME Sec III Div 2.

Kalkhedon Products offers customers’ a broad range of engineered mechanical splice systems for the benefit of the reinforced concrete construction industry. By means of market leadership, sales expertise and worldwide distribution, we consistently provide customer-focused solutions that provide the highest quality results and cost-effective installations.

Kalkhedon dowel bar replacements have the advantage of permitting continuity of reinforcement across construction joints without formwork penetration. Because flanged couplers are typically fully embedded in concrete, their use eliminates projecting bars, thereby relieving constructability problems and potential worker injuries.
