PURPOSE:To increase strength of forms and working efficiency, by using concrete blocks as a form used for a concrete building foundation and constructing dry forms with fastened steel bars and base plates. CONSTITUTION:Anchors 2 are fastened every certain interval on the ground, on which a ...
An effective solution is to use wire cages: these are fastened to the bottom of the form and clearly indicate where anchors and tendons need to be placed separately [5]. Again, similar structural challenges and their solutions are provided in further detail by existing educational literature....
Procedure to nail steel anchors by mechanical devices in concrete, masonry work and similar materials, characterized in that the hammer kinetic energy, during each penetration phase is exerted in coaxial direction to the body axis of the anchor by a stamp located on the anchor and because this ...
Improvements in the object of the patent of invention no. 215212 for process and device for driving steel anchors by mechanical hammering devices in concrete, masonry work and similar materials, characterized by an anchorage guided in a determined manner in at least two axially spaced positions, ...
SOLUTION: A box-shaped bracket 6 is arranged at the front end section of a separator 3, in which the base end section side is fixed onto an existing concrete wall 1 by anchors, while a connecting fitting 9 is projected and disposed at the place of coupling with the separator 3 on the...
