[0003] This method, on the one hand, after the lattice column is broken, the fragments cannot be used for other purposes, and can only be sold as construction waste, which is a pity; on the other hand, even if certain shock absorption and safety protection measures are taken during the crushing process, but In the process of breaking the lattice column, not only the falling fragments are in the danger of falling from a high altitude, but also the breaking process will cause vibration and impact to the structure, causing the structure to leave a safety hazard

Embodiment Construction
[0025] The method for removing the lattice column of the present invention will be further described in detail below.
[0026] The invention will now be described in more detail with reference to the accompanying drawings, in which preferred embodiments of the invention are shown, it being understood that those skilled in the art may modify the invention described herein and still achieve the advantageous effects of the invention. Therefore, the following description should be understood as the broad knowledge of those skilled in the art, but not as a limitation of the present invention.
[0027] In order to make the purpose and features of the present invention more comprehensible, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpo...

The invention provides a lattice-column dismounting method. Firstly, the upper portion of a lattice column to be dismounted is cut, so that the lattice column is divided into an upper column section and a lower column portion body; a chain block is arranged on the upper column section, one end of the chain block is provided with a stay cable, the other end of the chain block is provided with a pothook, the upper end of the lower column portion body is hooked by the pothook, and the chain block is tightened through the stay cable; then inclined cutting is conducted on the lower portion of the lower column portion body, so that the lower column portion body is divided into a column body middle section and a column lower section; finally, the lower end of the column body middle section is pulled sideward through a pulling rope, the pothook is gradually released downwards at the same time, and therefore the column body middle section is taken down. When the lattice column is dismounted, the chain block is used for lifting, so that impact damage to the structure caused by an existing crushing method is avoided, and meanwhile fragment high-altitude falling accidents are eliminated. Thus, because the main body of the lattice column can be used after being stored, very prominent economic benefits are obtained.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for removing lattice columns. Background technique [0002] At this stage, most of the temporary lattice columns are dismantled using the cutting method, which specifically refers to setting up a temporary scaffolding system on one side of the lattice column, breaking the lattice column into small pieces from top to bottom, and then stacking them in one place Waiting to be moved. [0003] This method, on the one hand, after the lattice column is broken, the fragments cannot be used for other purposes, and can only be sold as construction waste, which is a pity; on the other hand, even if certain shock absorption and safety protection measures are taken during the crushing process, but During the crushing process of the lattice column, not only the falling fragments pose the danger of falling from a high altitude, but also the crushing process causes vibr...
