Problems solved by technology
The traditional construction protection platform is manually welded to the steel column. It is difficult and dangerous to work at heights. After the steel column is docked, the platform needs to be dismantled and cannot be reused. For steel columns of different specifications and sizes, the protection needs to be remade. The platform, labor, materials, and mechanical equipment are hugely consumed, which will result in expensive measures

Embodiment Construction
[0027] Such as Figure 1-6 As shown in the figure, 1 is a triangular steel wedge, 2 is an operation adjustment platform, 3 is a corbel avoidance platform, 4 is a lifting lug, 5 is a pull ring, 6 is a positioning bolt, and 7 is a fixed platform.
[0028] The straight-moving protection platform of the present invention includes a rectangular mobile operation adjustment platform 2 around the steel structure column and a mobile corbel avoidance platform 3 between adjacent operation adjustment platforms. A fixed platform 7 is arranged around the structural column, and the upright triangular steel wedge 2 is welded around the steel structural column, and the fixed platform and the connection end of the steel structural column are welded with an inverted triangle that forms a clamping position with the upright triangular steel wedge. A steel wedge, four lifting lugs 4 and a pull ring 5 are arranged on the fixed platform.
[0029] As for the vertically movable protective platform, th...

The invention relates to steel structure construction. A vertically-moving protection platform is mainly composed of a fixed platform, bracket avoidance platforms and a column operation adjusting platform system; the fixed platform is mainly used for providing internal and external force transmission of a construction protection and consuming system. The fixed platform and the bracket avoidance platforms work together to generate a bunching effect; the bracket avoidance platforms have the main effect that regarding multi-section column butt-joint positions, reserved brackets for mounting steelgirders are arranged, and aisles are made by adjusting the bracket avoidance platforms, so that the vertically-moving protection platform lifts smoothly; operation adjusting platforms have the main effects that regarding steel columns of different specifications and sizes, distances are adjusted, so that the operation adjusting platforms are in contact with and clamp the steel columns to fix thewhole vertically-moving protection platform; the operation adjusting platforms can move freely, inverted triangular steel wedges are welded to the ends, in contact with the steel columns, of the operation adjusting platforms, and the inverted triangular steel wedges and triangular steel wedges are clamped to prevent the vertically-moving protection platform from falling, wherein the triangular steel wedges are welded to the steel columns. The vertically-moving protection platform is convenient to operate, safe, reliable and capable of being recycled, and the working efficiency is improved.
Description
technical field [0001] The invention relates to steel structure construction, in particular to a protective platform for installing multi-section columns in steel structure construction. Background technique [0002] At present, the installation of multi-section columns of steel structures generally requires butt welding or bolt connection of the upper and lower section columns at high altitudes, and a temporary construction protection platform needs to be erected below the butt joints to provide construction workers with a working surface. The traditional construction protection platform is manually welded to the steel column. It is difficult and dangerous to work at heights. After the steel column is docked, the platform needs to be dismantled and cannot be reused. For steel columns of different specifications and sizes, the protection needs to be remade. The platform, manpower, materials, machinery and equipment consume a lot, which will result in expensive measures. Co...
