TH10832C3 - Installation method of precast concrete wall panels with hollow holes - Google Patents

Abstract

New request, revised 18/8/2016 This invention is to develop a method for installing pre-hollowed concrete walls to prevent unwanted cracks in the building walls. Installing wall panels to the building structure such as floor columns or concrete beams There will be a dowel bar to be fixed between the panels. With building structure Add shear key to the junction between the wall panels and the fiber glass mesh to strengthen the junction between the wall panels. Which processes Install the walls according to this invention. This will help prevent cracks in the joints between the wall panels and the joints between the wall panels and the building structure. Which results in building walls that are stable, strong and Neat and beautiful Reduce the problem of cracking of the wall
