A SET OF PREFABRICATED TRAVELLING TUNNEL-TYPE FORMS Russian patent published in 1997 - IPC

FIELD: equipment applicable in erection of residential and public cast-in-situ buildings with a set of prefabricated travelling tunnel-type forms. SUBSTANCE: a set of prefabricated travelling tunnel-type forms has tunnel-type forms for one setting including prefabricated L-shaped panels-semitunnels and L-shaped panels with end face which form tunnel when assemble by pairs. Forms set includes embedded members in form of concrete crosses installed between semitunnels to adjust the latter in the upper position, fastening members to butt the panels to one another, braces of adjustable length and load-carrying channel beams to impart rigidity to panels comprising the system of form stabilization, rollers for forms travelling and auxiliary equipment - scaffolds. Load-carrying parallel channel stiffening beams of vertical panels are reinforced with longitudinal walls of channels on panels and installed in a spaced relation to each other, and provided with coupling device in form of additional inserts of channel section of smaller size in places of joining of vertical panels. Inserts are located on both sides of joined panels inside the stiffening beams and secured with each other by threaded joints. Members of fastening of ceiling panels to each other are made in form of a pair of bolts of retainers with pivot secured on different sides of joined panels. Pivot has locating pin inserted into respective recess of panel. Auxiliary equipment-scaffords are installed at the same level over the periphery of the building. Fastening members of bolts-retainers are made in form of locking turning clamp. EFFECT: higher efficiency. 2 cl, 11 dwg
