Abstract
A core sampling device of the type utilized in forming concrete test cores in situ including a double-walled sleeve which is placed into the wet, fluid concrete in combination with an insertion tool whereby the sleeve, due to its configuration, may be pressed or "screwed" into the fluid concrete. By virtue of the double-walled construction of the sleeve, once the concrete has cured, the test core may be easily removed therefrom.
Claims8
A core sampling device of the type primarily intended for forming concrete test cores in situ and facilitating the removal of such test cores, said core sampling device comprising:
- sleeve means comprising first wall means defining the exterior of said device and second wall means correspondingly configured as said first wall means and disposed within said first wall means, said first and second wall means being interconnected at their bases;
- a plurality of insertion ledge means formed in interconnecting relation between said first and second wall means bases;
- and insertion means removably engageable with said sleeve means, said insertion means comprising body means dimensioned and configured for being removably disposed within the space defined between said first and second wall means, said insertion means further comprising a plurality of insertion finger means formed around a peripheral edge of said body means, said finger means being dimensioned and configured to operatively engage said insertion ledge means, whereby said insertion means may be utilized to place said sleeve means within fluid concrete to form a test core at least partially defined by said second wall means.
