Problems solved by technology

Compared with ordinary carbon steel, aluminum alloy has the advantages of lighter weight and corrosion resistance, but its corrosion resistance is not as good as that of pure aluminum. A protective oxide layer will form on the surface of aluminum alloy in a clean and dry environment.

Abstract

The invention discloses a support device for an early-demolished formwork. The support device comprises a support device body. The support device body comprises a bottom fixed rod. A strut is connected to the top position of the bottom fixed rod. An outer thread is arranged in the position, close to the top, of the surface of the strut and is provided with an adjusting nut in a matched mode. A movable casing is arranged in the position, located at the top of the adjusting nut, of the surface of the strut. Support blocks are arranged on the left and right sides of the movable casing. Extendingblocks are arranged in the positions, close to the outer sides, of the top faces of the support blocks. First extending blocks are arranged in the positions, close to the inner sides, of the top facesof the support blocks. The support device is provided with the adjusting nut matched with the movable casing, thus convenience is provided during both installation and demolition, meanwhile, if one is different from others in height, fine adjustment can be conducted through a connection bolt, and the overall stability is improved through the arrangement of a fixed base. The strut is prepared fromaluminum alloy materials according to a conventional process.

Description

technical field [0001] The invention relates to a supporting device for an early demolition formwork. Background technique [0002] Early demolition of the formwork is a formwork support device and method adopted to realize the early demolition of the floor formwork. Its working principle is "remove the slab without dismantling the columns". Keep the span of the floor formwork not exceeding the span requirements specified in the relevant codes, so that the floor formwork and some supports can be removed as long as the concrete strength reaches 50% of the design strength, while the inter-column, column and adjustable support remain in the support state , when the concrete strength meets the design requirements, remove all vertical supports. In order to reduce the consumption of energy and resources and slow down the damage to the environment, the Chinese government followed the world trend and promulgated the "Green Building Evaluation Standard" in early 2006, followed by th...
