Abstract

The invention relates to a device and method for the removal construction of vertical posts positioned on the lower part of a large-span net rack. The device comprises the large-span net rack, a temporary supporting structure, a fixed structure, an installation device and an operation scaffold, wherein the large-span net rack comprises a target removing support post, a pair of fixed support posts and a net rack top surface, wherein the pair of fixed support posts are arranged at both sides of the target removing support post, the net rack top surface is arranged on the upper ends of the pair of fixed support posts, and the pair of fixed support posts include a first fixed support post arranged at one side of the target removing support post and a second fixed support post arranged at the other side of the target removing support post; the temporary supporting structure is arranged between the net rack top surface and the ground; the fixed structure is fixedly arranged below the net rack top surface; the installation device comprises an autocrane and a pair of hoisting machines; and the operation scaffold is arranged on the bottom surface positioned below the large-span net rack, surrounds the temporary supporting structure and upwards extends to the lower side of the net rack top surface. The invention has the advantages of effectively controlling the risk of construction, realizing the transformation of building functions, meeting the requirements for construction safety and progress and reducing the construction cost.

Description

technical field [0001] The invention relates to a building engineering construction technology, in particular to a construction device and method for extracting columns at the lower part of a large-span network frame. Background technique [0002] In construction projects, if the building is a steel structure and is quite old, the renovation process needs to take the old structure as the frame, attach the old structure, and rebuild the stadium inside. The construction risk control and reasonable plan layout are crucial to the success or failure of the project. play a decisive role. The main disadvantage of the prior art is that it has a great influence on the construction progress and increases the construction cost. [0003] In view of the above problems, the present invention discloses a construction device and method for extracting the lower column of a large-span network frame. It has the technical features as described below to solve the existing problems. Contents ...
