Cantilever frame vertical rod safety positioning device and construction method thereof

Abstract

The invention discloses a cantilever frame vertical rod safety positioning device and a construction method thereof, and belongs to the technical field of cantilever beam positioning construction. The cantilever frame vertical rod safety positioning device comprises a vertical rod, wherein a foot locking rod is arranged in the vertical rod, a clamping sleeve is fixedly connected to the bottom of the foot locking rod, the foot locking rod is fixedly welded to the clamping sleeve, the vertical rod is matched with the foot locking rod in an inserted mode, the clamping sleeve is composed of an upper steel plate and a lower steel plate, and an outer hexagon bolt is jointly installed on the plate surfaces of the upper steel plate and the lower steel plate. According to the cantilever frame vertical rod safety positioning device and the construction method thereof, the structure is simple, operation is convenient, the vertical rod is matched with the foot locking rod in the inserted mode so as to achieve the anti-skid and positioning effects, the vertical rod is used for external protection of a main body structure to form an outer scaffold system, the construction high-altitude safety is guaranteed so as to facilitate operation of constructors, I-shaped steel is a stress bearing device of the outer scaffold system, by using the vertical rod safety positioning device, the adjustment of the position of the vertical rod is more flexible, simpler and more convenient when a cantilever scaffold is erected, and the construction convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cantilever beam positioning construction, and more specifically relates to a cantilever beam safety positioning device and a construction method thereof. Background technique [0002] In the process of building construction, especially when it involves high-rise and super-high-rise construction, in the construction of cantilevered scaffolding, different types of I-beams are selected as cantilevered beams according to the design requirements of the scheme, and the upper scaffolding pole stands on it. Due to the limitations and particularities of the building structure and the erection site, there are different design requirements for the cantilever section of the section steel protruding from the building and the anchor section inside the building. The traditional "external frame pole positioning pile" is to directly weld a short steel bar head or short round tube on the cantilever beam, but many uncertain...

Problems solved by technology

The traditional method of "outer frame pole positioning pile" is to directly weld a short steel bar head or short round tube on the cantilever beam, but many uncertain factors on the construction site make it impossible to accurately insert the outer frame pole into it. The construction operation procedures are cumbersome and require the on-site cooperation of welding and cutting workers to complete, and because of welding technology and environmental influences, the welding quality cannot be guaranteed; the welding pile head cannot move freely according to needs, and the installation process of different construction methods is very restricted; the removal of the cantilever When steel beams are stored and stored, the welding pile heads are in the way, and the pile heads are basically removed by the workers, which cannot meet the national environmental protection requirements for energy conservation and emission reduction. In this case, the positioning piles directly welded on the cantilever beams will not work. became an obstacle

Especially in special parts such as the corner position of the structure or the reserved opening, due to the different requirements for the length of the cantilever beam, it will affect the accuracy of the establishment of the position of the upper pole. It will be very troublesome to adjust
