Anti-falling full framing structure and construction method

Abstract

The invention discloses an anti-falling full framing structure and a construction method. The structure comprises a full framing body. A bottom support is arranged below the full framing body; a jacking is arranged above the full framing body; and a cast-in-place beam is arranged above the full framing body, a door opening is arranged in the full framing body, stand columns are arranged on the twosides of the door opening, a distribution beam is arranged above the door opening, bearing beams are arranged between the stand columns and the distribution beam, extending plates are arranged at thetwo ends of each bearing beam, and a strip-shaped bamboo plywood is arranged between the extending plates of every two adjacent bearing beams. Stress safety of the structure is guaranteed, and meanwhile the strip-shaped bamboo plywood arranged on a cross beam extension plate in a lap joint mode well prevents objects falling from the upper portion of the door opening from high altitudes. An effective driving width of a bracket passing door opening is increased, the structure and the method are suitable for erecting a large-span passing door opening, a stress system is good, and the construction safety can be ensured. Life and property losses caused by falling objects above the passing door opening can be effectively prevented.

Description

technical field [0001] The application relates to the field of bridge engineering construction, in particular to a structure and construction method of a fall-preventing full hall support. Background technique [0002] In recent years, with the development of urban bridges, in addition to meeting the basic requirements of traffic, the design function of modern bridges has added requirements such as landscaping, which has led to the emergence of more bridges with complex structures and various forms. The superstructure of many large and medium-sized bridges in China has adopted variable cross-section cast-in-place box girders, and the construction methods are different. [0003] The full hall bracket is a common support form in engineering construction. In order to meet the normal traffic of existing traffic roads during the construction period, it is necessary to build a doorway structure at the place where the existing traffic passes through the cast-in-place beam full hall...

AI Technical Summary

Problems solved by technology

This support system can reduce the area of ​​foundation treatment, and is especially suitable for areas with complex terrain. At the same time, it reduces the amount of steel pipes, bowl fasteners, etc., increases the space of the site, and makes the support system more stable. However, it does not solve the problem of passing vehicles and pedestrians under the door opening. safe question
