Metal keyway for concrete slabs.
16 gauge avail able on special order.
I m having a 24 x 18 4 slab poured tomorrow and the concrete guy said to use a keyway on the middle to have something to straight edge by and also be used for an expansion joint.
Using the quickey system reduces installation time and provides for a smoother level pour.
Keyways are not recommended for thin slab less than 250mm thick because of the difficulty in construction.
It is a stay in place metal keyed control joint former.
The false form k30 is fabricated in 18 gauge metal for 8 to 12 slabs.
Meets aci and pca recommendations.
We will go back after a few days and saw cut lines through.
Though the installation of keyway joint does not appear to increase the load transfer efficiency of longitudinal joint it proves to help reduce the deflection of concrete pavement.
It has square knockouts for square and round dowels.
This provides better load transfer over round dowels and also reduced edge curl in slabs.
Quickey is a stay in place metal keyed control joint former.
In this video i take you along as we pour a 36x46 concrete slab for a steel building to go on.
These relatively simple tools not only allow for multiple slabs or strips of concrete to be poured at once but they also minimize the risk of cracking within your slabs.
K30 and k33 metal keyway center strip metal keyways are available to form keyways along longitudinal and transverse joints in concrete slabs.
If keyways are to be used in such circumstances it might be well to thicken the edge to 6 inches and use a keyway made for a 6 inch thick slab.
I though i remember reading that you shouldn t use one in a slab that thin.
This product is for use in concrete flatwork as a control or construction joint.
Manufactured of 24 gauge g60 hot dipped mill galvanized steel.
Standard steel forms are often constructed with a keyway in place.
The small amount of concrete above the keyway in a 4 or 5 inch thick slab offers less resistance to spalling than in a thicker slab.
Qk35 is used in concrete applications.
Helps minimize floating.
Metal screed joint keyway concrete accessories.
Is that true or will it be ok.
The general center strip k33 is fabricated in 18 and 20 gauge metal for 5 to 10 slabs.
Keyfold joint systems.
We offer a galvanized keyfold joint system for concrete slabs in depths of 3 4 6 8 10 and 12.
Proper steps for using screed key joints in concrete slabs to make pouring multiple slabs of concrete more efficient screed key joints can be used.
Keyways are formed with templates of metal or wood.
The slab may be too thin.
Any wood insert in concrete such as a keyway should be well soaked in water prior to concrete placement or be resin sealed.
