Background of Early-stripping aluminum formwork system
It is an objective for which owners and construction units have been striven to bring forward or shorten the construction period. For this purpose, it is undoubtedly a solution to equip with a large amount of formworks and workers, for example, one identical construction site is equipped with a plurality of sets of formworks, which however, will increase the construction cost greatly. Thus an early-stripping formwork set-forming technology only needing one set of formwork as well as several sets of props becomes the best solution recognized by persons of the same occupation at home and abroad. Existing foreign systems have too high costs and are inappropriate to the domestic building structures.
The Value of Early-stripping aluminum formwork system
The invention is aimed to provide an early-stripping aluminum formwork system for construction comprising beams, slab and columns which has low transportation and storage cost and is convenient to use, overcome the short comings of the past existing early-stripping aluminium formwork system of construction of floors comprising beams, slab and columns
Technical solutions of Early-stripping aluminum formwork system
An early-stripping aluminium formwork system for concreting of constructions comprising beams, slab and columns, comprising several standard formworks, props with multiple early-stripping support mechanisms, several filler beams mainly used for supporting construction beams of floors, and filler panels; the standard formwork consists of a panel and a formwork frame and is in right-angle quadrilateral shape, and the formwork frame of the standard formwork is provided with L-shaped corners at its four corners; the early-stripping prop consists of an upper support inner tube and a lower support outer tube which forms a telescopic connection, a rectangular head plate is disposed at the top end of the upper support inner tube, and one corner of the head plate is complementary to an internal corner of any one of the L-shaped corners on the formwork frame; a load-releasing mechanism which causes the upper support inner tube to descend by a predetermined height is connected between the upper support inner tube and the lower support outer tube; an early stripping mechanism for early stripping of the standard formwork is disposed on the upper support inner tube, short posts for supporting the formwork frame are disposed at four corners of the early stripping mechanism, and a structure for preventing the formwork frame from slipping outwards is formed between the short post and the L-shaped corner; the formwork frame is in a detachable combined structure.
The early stripping mechanism, the load-releasing mechanism and the rectangular head plate are in correspondingly the same structure with the early stripping mechanism, the load-releasing mechanism and the rectangular head plate in the patent publication CN101591973A respectively.
In the invention adopting the preceding technical solution, due to the adoption of the detachable combined structure, the formwork frame can be detached into parts and components before being stored and transported for the convenience of storage and transportation, which can efficiently save space of storage and transportation and reduce warehouse capacity and transport capacity, thereby reducing cost of storage and transportation and being convenient to use.
