Specifications of Main Parts for Space FRAME
Supporting Type of Space Frame
Periphery-supporting S pace Frame(Fig.6) This supporting type is widely used as it transmits force directly and gets evenly. Point-Supporting S pace Frame(Fig.7) The space frame can be put on 4 or more-point support with upper chord or column cap supporting's(Fig.8).
Combined Periphery and point Supporting S pace Frame This kind of support is specially suited to t he large area industry workshop and other architecture. Three-side-supporting One-side-opening(Fig.9)or Two-side Supporting Two-side Opening(Fig.10)S pace Frame In this case,the un supporting side(free sides)should specially be treated, such as increasing layer of space frame near the free sides,adding joints or increasing the height o f space frame.
Structures of supporting joints and suspending joints
Main Installation Method of Space Frame
Full Scaffold Aerial Bulking method(Fig.12) This installation method is applied to the bo lted-ball joint space Frame,and in places where there is no enough hoisting capacity and the full scaffold can be set up. Aerial Sliding method(Fig.13) This assembling method is applied to the places where is a hoisting area and ho isting area and hoisting equipment. Integral Hoisting Method(Fig.14) This assembling method is applied to the places where is a hoisting area and ho isting equipment. Working Platform Sliding Method(Fig.15) This installation method is applied to the large pillar supporting space frame with fine stiffness.
