DEVICE FOR FIXING OF SHUTTERING PANELS Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: this relates to civil and industrial building activities, and particularly to design of devices for fixing panels of shuttering used in concrete work. Device for fixing shuttering panels is made in the form of rod installed in coaxial holes of panels which are located in parallel planes. Device is located between panels of spacer member. Rod is inserted into hole of spacer member. Device has nuts which are turned on end parts of rod. Rod is made of lengths of reinforcing rod with diameter preferably of 12-16 mm. Each nut is of standard type-size and with thread corresponding to profile of reinforcing rod so as to allow for fastening nuts on rods of various diameter. At least threaded part of nut is slotted in length into segments which are bracket-like secured on members which are elastically deformable by means of holder which embraces them. Holder is movable along axis of rod. Holder is made preferably in the form of external nut. Nut can be made slotted into segments which are located in holder with possible radial preferably synchronous movement relative to rod and fixing in preset position. Spacer member can be made in the form of bush. Diameter of hole in bush exceeds diameter of rod over circumference of protrusions by 0.1-2.0 of rod diameter. Bush is of cylindrical and/or taper or double-taper configuration over entire length or on separate sections. Application of aforesaid embodiment of fixing device allows for reduction of material- and labour-input due to fact that utilized in function of rods are basically discarded pieces of reinforcing rods together with minimized amount of nuts and this makes construction operations speedier. EFFECT: higher efficiency. 3 cl, 2 dwg
