Early-removal formwork system for concreting of constructions comprising beams, plates and columns

Abstract

The invention discloses an early-removal formwork system for concreting of constructions comprising beams, plates and columns. The early-removal formwork system comprises a plurality of rectangular standard forms, a plurality of early-removal support columns, a plurality of auxiliary beams and auxiliary forms. Each standard form comprises a face plate and a form frame, and the form frame is provided with L-shaped corner pieces at four corners. Each early-removal support column comprises an upper support column and a lower support column in telescopic connection, a rectangular top plate is disposed at the top end of the upper support column, one corner of the top plate and an internal corner of the optional L-shaped corner piece on each form frame are complementary, an unloading mechanism is connected between the upper support column and the lower support column, an early removal mechanism for early removal of the standard forms is disposed on the upper support column, short support posts for supporting one form frame are disposed at four corners of the early removal mechanism, and a structure for preventing the corresponding form frame to slip out is formed between each short support post and the corresponding L-shaped corner piece. The form frames, the auxiliary forms, the auxiliary beams and suspension beams are all in removal combined structures. The early-removal formwork system has the advantages that no secondary auxiliary beam or secondary auxiliary form is needed, specifications and amount of forms are reduced, transport and storage are facilitated, volume and capacity can be reduced effectively, and material management and cost reduction are benefited.

Description

technical field [0001] The invention relates to a formwork and scaffolding for building construction equipment, in particular to an early demolition formwork system for pouring buildings with beam, plate and column structures. Background technique [0002] The advance or shortening of the construction period has always been the goal pursued by the owners and construction units. It is undoubtedly a solution to rely on a large number of formwork and staff. For example, multiple sets of formwork are equipped on the same site, but this will greatly increase the construction cost. cost. Only one set of formwork plus several sets of pillars is needed, which is the best solution recognized by international and domestic counterparts. Existing foreign systems cost too much and are not suitable for domestic building structures. Even the systems that are very popular abroad, such as PERI in Germany, are composed of pillars, beams, plates and many accessories due to their structural de...

Problems solved by technology

However, the frame of the formwork is a welded rigid structure, which takes up a lot of space for transfer and storage, resulting in inconvenient transportation and storage and high costs.

At the same time, the auxiliary formwork and the secondary auxiliary formwork have the same structure as the formwork and need to be made into various specifications, which will also cause inconvenient transportation and storage and high cost, and will also increase manufacturing costs.
