A process for the construction of an aluminum alloy formwork in the rear of the stair section

Abstract

The invention discloses process for stair bench one-layer-postponed construction with an aluminum alloy formwork. The process comprises the following steps that the construction of a N-1 layer beam plate is completed, and pouring space of a N-1 layer ladder beam used for connecting an upper bench is reserved; the construction of a N layer beam plate wall is completed, and the pouring space of a Nlayer ladder beam is reserved; the construction of N+1 layer beam plate wall, the N-1 layer ladder beam used for connecting an upper bench, N-layer bench and a N-layer ladder beam used for connectinga lower bench are completed, and the pouring space of the N+1 layer ladder beam and the a N-1 layer ladder beam used for connecting an upper bench are reserved; the construction of N+2 layer beam plate wall, N layer ladder beam used for connecting an upper bench, N+1 layer bench and the N+1 layer ladder beam used for connecting a lower bench are completed, and the pouring space of N+2 layer ladderbeam and the N+1 layer ladder beam used for connecting an upper bench are reserved; the previous step is repeated until the pouring of the last standard layer M layer is completed; and the construction of pouring a M layer bench, M+1 layer ladder beam used for connecting an upper bench and M layer ladder beam used for connecting a lower bench is completed. The process for the stair bench one-layer-postponed construction with the aluminum alloy formwork has the advantages that a large number of special-shaped plates are reduced, tread surfaces no longer have bubbles, disassembly and assembly by workers is simple and quick, and good technical and economical effects are achieved.

Description

technical field [0001] The invention relates to a stair construction method of an aluminum alloy formwork, in particular to a construction process in which an aluminum alloy formwork is placed behind a staircase section. Background technique [0002] After the aluminum alloy formwork system has matured, it is widely used in various fields of reinforced concrete structures, and has also been applied and developed in stairs. [0003] At present, the aluminum formwork for stairs adopts a fully enclosed formwork method. In addition to supports, fasteners and accessories, aluminum formwork for stairs mainly includes wall formwork, beam formwork, floor formwork, stair floor, step Cover plate, side sealing plate of steps and various corner components. Due to the complex structure, various forms and many corners of the stairs, there will be a large number of non-standard parts, which can only be used in a certain building and are not universal. [0004] The aluminum alloy formwork...
