Platform beam for cantilever structure

Abstract

The invention provides a platform beam for a cantilever structure, the cantilever structure is a concrete single cantilever beam, and the platform beam comprises a special-shaped superposed clamping sleeve beam; the special-shaped overlapped clamping sleeve beam comprises long I-shaped steel and T-shaped steel; the T-shaped steel is fixedly connected to the two ends of the lower portion of the long I-shaped steel and arranged on the two sides of the concrete single suspension beam. The special-shaped overlapped clamping sleeve beam is clamped with an embedded part above the concrete single suspension beam through long sleeve sets arranged on the two sides of the long I-shaped steel; the special-shaped overlapped clamping sleeve beam is fixedly connected with a concrete single cantilever side face embedded anchor plate assembly through a connecting end plate on the side, close to the concrete single cantilever side face, of the long I-shaped steel. Each truss of platform beam extends towards the cantilevers at the two ends on the cantilever beam, so that expansion of the vertical rod foundation of the formwork support is achieved, it is guaranteed that the height-width ratio of the formwork support meets the standard requirement, and the accident risk of overturning and collapse is avoided.

Description

technical field [0001] The invention relates to the technical field of high-altitude formwork support for single cantilevered beams, in particular to a platform beam used for a cantilevered structure. Background technique [0002] When independent cantilever beams are used to support formwork at high altitudes, if only the poured independent cantilever beams on the lower floor are used as the pole foundation, the width of the foundation will be insufficient, resulting in the height-to-width ratio of the erected formwork frame seriously failing to meet the specification requirements and prone to overturning and collapse. Extended pole base. Therefore, it is necessary to arrange a number of platform beams perpendicular to the independent cantilever beams on the poured independent cantilever beams as the foundation of the formwork frame. The cantilever extends to both ends, so as to realize the expansion of the vertical rod foundation of the formwork frame, so as to ensure tha...

Problems solved by technology

[0003] In the prior art, the solution for high-altitude formwork support of independent cantilever beams usually avoids the setting of concrete independent cantilever beams and replaces them with steel structure independent cantilever beams. Therefore, fire prevention and anti-corrosion performance are prone to fail to meet standards, and there are huge potential safety hazards

For the single cantilever beam solution, there is currently no good high-altitude formwork support solution to ensure the safety and stability of the formwork support platform as well as the bending and shear resistance performance. Therefore, there is an urgent need for a single cantilever beam formwork support platform system that meets the requirements of fire prevention and corrosion protection.
