One-way building formwork

Abstract

The invention discloses a one-way building formwork which is capable of saving materials, simple in force transmission, not prone to deforming, good in bearing effect and convenient to construct. The one-way building formwork comprises a panel (1), lateral longitudinal rib plates (2) which are located on the two sides of the panel (1) and are equal to the panel (1) in length, at least one inner longitudinal rib plate (4) which are located between the lateral longitudinal rib plates (2) and are equal to the lateral longitudinal rib plates in length and parallel to the lateral longitudinal rib plates, a plurality of seal plates (3) located at the two ends of the panel (1) and a plurality of transverse reinforcing ribs (5) located between the lateral longitudinal rib plates (2) and / or between the inner longitudinal rib plates (4). The seal plates (3) enable the two ends of the panel (1), the lateral longitudinal rib plates (2) and the inner longitudinal rib plates (4) to be sealed, the two ends of the transverse reinforcing ribs (5) are fixedly connected with the lateral longitudinal rib plates (2) and / or the inner longitudinal rib plates (4) and used for providing stable constraint for the lateral longitudinal rib plates (2) and the inner longitudinal rib plates (4), the inner longitudinal rib plates (4) and the lateral longitudinal rib plates (2) are the same in height, the end faces of the inner longitudinal rib plates (4) are flush with the end faces of the lateral longitudinal rib plates (2), the side faces of the inner longitudinal rib plates (4) are flush with the side faces of the lateral longitudinal rib plates (2) and a plurality of parallel one-way main beams are formed by the lateral longitudinal rib plates (2) and the inner longitudinal rib plates (4) to divide the panel (1) into a plurality of one-way panel bodies. The one-way building formwork can be widely applied to the field of building formworks.

Description

Technical field [0001] The invention relates to a metal building template used in cast-in-place concrete structure engineering, in particular to a one-way building template. Background technique [0002] With the continuous development of the construction industry, the proportion of cast-in-place concrete structures is increasing, and labor costs are increasing. The traditional wooden formwork has low strength, few turnover times, and consumes a lot of wood and human resources; the steel formwork is heavy and difficult to demold, and construction requires mechanical equipment. Aluminum alloy building formwork is a new type of building formwork. It has the advantages of light weight, many turnover times, and low cost of multiple turnovers. It is gradually being used in cast-in-place concrete structures. Such as Figure 1~4 As shown, the existing aluminum alloy formwork includes a two-way panel 10 for supporting concrete, side ribs 20 located on both sides of the two-way panel 10 a...

AI Technical Summary

Problems solved by technology

This formwork needs to adopt several I-beams 50 in the form of two-way panels 10 and side ribs 20 to be connected. There are situations such as bulging deformation of the panels, and the size and welding area of ​​the stressed secondary beams are relatively large. The side ribs 20 are easily deformed under concentrated stress. Even if the improvement method of adding short longitudinal ribs inside is adopted to turn the panel into a partial one-way plate, the force still needs to be transmitted through the secondary beam, and there is no fundamental solution to the problem.

Therefore, the current formwork is easy to cause waste of materials, difficulty in guaranteeing welding quality, self-heavy and difficult construction, etc.
