Formwork supporting structure of dismounting-free external wall formwork

Abstract

The invention discloses a formwork supporting structure of a dismounting-free external wall formwork. The formwork supporting structure comprises two rows of external wall formworks, two rows of formwork positioning devices, two bases, an upper pressing device and a lower pressing device, wherein the formwork positioning devices are arranged at the outer sides of external walls arranged at two sides of a building and are connected with the external wall formworks; the bottom end of each formwork positioning device is connected onto the corresponding base; the tops of the two rows of external wall formworks are higher than the external wall of the building, and the upper pressing device is connected among the tops of the two rows of external wall formworks and the external wall of the building; and the lower pressing device is connected between each formwork positioning device and the building bottom structure of a support external wall. When the formwork supporting structure is used, the pressing force can be conveniently regulated; the supporting formwork is stable and firm; after the construction, the formwork supporting structure of the external wall formwork does not need to be dismounted; and after the formwork supporting structure is used for construction, the additional waterproof and heat insulation construction is not needed.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to the related structure of external wall formwork. Background technique [0002] In the field of building construction, it is often necessary to pour the external wall after supporting the formwork. In the traditional external wall construction, the formwork is often supported by the tension bolt against the tension formwork method. In many occasions, concrete walls (such as the outer walls of tunnels and subway station buildings) have waterproof requirements. The use of tension bolts to the tension formwork construction method is bound to destroy the integrity of the structure and reduce the waterproof performance of the wall. For exterior wall structures that require the effect of fair-faced concrete, the treatment of bolt holes in the prior art cannot achieve the effect of native fair-faced concrete. During construction, the installation and removal of tension bolts an...

Problems solved by technology

For the external wall structure that requires the effect of fair-faced concrete, the existing technology can not achieve the effect of original clear-faced concrete on the treatment of the bolt holes

The installation and dismantling of pull bolts and exterior wall formwork during construction increases construction steps and quality control links, reducing construction efficiency
