The following describes an embodiment of the present invention based on its overall structure.

Example

As shown in Figure 1-9, a high-rise building steel structure construction method includes the following steps: Step 1, design and preparation: conduct site survey, engineers determine the size, shape, material and specifications of the steel structure according to the architectural design drawings and relevant specifications, survey the construction site, determine the layout of the steel structure, foundation form, bracket type and other information, and perform relevant site leveling and preparation work; Step 2, building material hoisting mechanism enters the site: organize personnel to enter the site in advance, assemble the building material hoisting mechanism according to the plan, and test it for use; Step 3, electric forklift enters the site: lift the electric forklift through the building material hoisting mechanism and place it steadily on the roof; Step 4, building materials enter the site: personnel lift the columns and beams through the building material hoisting mechanism, place them steadily on the roof for use; Step 5, on-site Site construction: Workers will build the skeleton of the steel structure at the predetermined location in accordance with the requirements of the construction drawings to ensure the stability, rigidity and safety of the steel structure, and provide necessary support and guarantee for subsequent construction; Step 6, Painting and anti-corrosion: Workers will paint and anti-corrosion the steel to prevent the steel from being affected by corrosion and other damage, ensure the durability and aesthetics of the steel structure, and extend its service life; Step 7, Debugging and acceptance: Workers will debug and accept the completed steel structure to ensure that it meets the design requirements and standards. If there are defects or the requirements are not met, workers will repair and rectify them until they meet the design requirements and standards. Finally, personnel from the construction unit, supervision unit, design unit and other relevant parties will jointly participate in the acceptance to confirm that the project quality has reached the expected goals.

It should be noted that the construction steps of this application are clear to ensure the quality and progress of the installation project. In step one, the layout, foundation form, bracket type and other information of the steel structure are determined, and relevant site leveling and preparation work are carried out. The steel components are transported to the site according to the installation progress. After the components arrive at the site, the number and number of the components are checked according to the freight list on the vehicle to see if they match. If any problems are found, the manufacturer should take prompt measures to replace or supplement the components to ensure the urgent needs of the site. According to the actual needs of the site, the precise arrival time of each component and material is clarified, and a detailed component arrival plan is prepared. The arrival plan is accurate to the day and component number. The components are delivered to the site at the latest two days before the lifting. The limited storage yard on the site during installation is fully considered, and the relationship between the installation site and the production and processing is coordinated as much as possible to ensure that the installation is carried out as planned. The markings of the components should be exposed and can remain durable and can withstand sunlight and wear. If necessary, steel stamps can be used for easy identification and inspection in case of special conditions such as damage, wind and rain erosion, etc. The markings of bundled components should be in one direction, and there should be a summary of the components on the outer packaging. The summary should accurately include the information of the components and materials in the bundle. The packed components should be numbered and there should be a detailed summary of the components outside the box. The summary marks should be clear and recognizable. Pay attention to the safety of hoisting and stacking of component loading and unloading to prevent accidents. Contact the on-site command center before the components enter the site, and coordinate and arrange the yard, unloading personnel, and machinery in a timely manner. For large quantities and multiple vehicles entering the site at one time, the entry order, entry time, and queue parking positions of all vehicles should also be clarified. After the components are transported to the site, the handover and acceptance procedures should be handled according to the prescribed procedures. The loading, unloading, transportation, and stacking of components must be explained to the workers and drivers so that each worker and driver is clear about the work content and precautions, etc., to ensure the safety and efficiency of the components entering the site;

Furthermore, after entering the site, the components are inspected on site to ensure the specifications, quantity, weld quality, coating quality, component appearance and size inspection, and the acceptance and handover of production materials. The focus of quality control is on the steel structure manufacturing plant. After inspection, components with defects exceeding the allowable deviation range are repaired on site. They can only be accepted after meeting the requirements. Components that cannot be repaired on site should be sent back to the factory for repair;

Furthermore, in step 4, based on the site conditions, the site conditions should be fully utilized as much as possible. The assembly, installation and other professional construction sites will not produce plane interference and three-dimensional intersection to avoid affecting the various construction sites on site. The building materials hoisting organization should prepare for the laying of pipelines and the erection of lines in advance. The component entry plan and the on-site installation sequence should be appropriately adjusted and transferred when necessary to minimize the secondary transportation of components and meet the construction needs of the site. When hoisting and stacking components, they should be stacked in an order that is convenient for installation, that is, the components installed first should be stacked close to the assembly equipment or hoisting equipment, and the components installed later should be stacked in a place that is convenient for hoisting. When stacking components, be sure to expose the component numbers and logos for easy viewing. During steel structure construction, other professionals are under construction at the same time. The time of steel component material entry and the layout of the stacking site should take all parties into consideration. When unloading, stacking and sorting components, personnel safety briefings and protective measures should be carried out, and mechanical equipment inspections should be carried out to prevent safety accidents.
