SYSTEM FOR INSTALLATION OF FORM NEAR INNER-CORNER OF STRUCTURE

摘要

PURPOSE: A system for installation of a form is provided to make the form easily used and released and to protect swelling of the form by pressure of concrete introduced into the form. CONSTITUTION: The system comprises a rectangular beam(100); two sheets of connection panels(120) adjacent to the beam(100) and to support inner side of concrete introduced; a general panel(110) lined to the panels(120); and a coupling pin(200) to engage the beam(100) and the panels(120). The beam(100) is straightly set up on top side of a cross bar. The cross bar is perpendicular to another cross bar placed on top side of a concrete floor. Two sides crossing above the beam(100) have a number of elongated hollows and are arranged inside inner corner of a structure. Each of the sides is adjacent to respective connection panel(120).
