1, construction height of more than 50m curtain wall installation project;
2, construction height of more than 80m of the facade of the painting, refurbishment, lighting installation and other works;
< Strong>3, special installation form and the addition of sub-basket basket construction.
3.0.4 provisions as follows: 3.0.4 basket construction object is usually the building facade decoration works. According to the provisions of the Ministry of Construction General Office of the building office quality [2018] No. 31, the height of the building curtain wall installation project to reach and exceed 50m belongs to more than a certain size of the danger of large sub-items of the project needs to be organized expert technical demonstration, but the non-curtain wall hanging basket construction is not clear. Therefore, the provisions of this article, when the curtain wall construction selection of hanging basket as a construction platform, reaching and exceeding 50m hanging basket construction program should be with the curtain wall construction program - or separate organization expert technical demonstration. When the building facade painting, facade refurbishment and sporadic lighting, equipment installation project selection of hanging basket as a construction platform, due to the construction content is relatively single, it is appropriate to give relaxation, the provisions of the suspension device installation height more than 80m ( including ) when the need to organize expert technical demonstration. Special installation form of hanging basket due to installation conditions, installation surface bearing capacity, program design and special installation form of components production and processing quality uncertainty is greater, involving more factors of safety construction, so the provisions of any installation height of special installation form of construction should be organized expert technical demonstration. Special emphasis, the basket special construction program must pay special attention to the basket installation configuration table and the installation of the preparation of the layout plan. They are to guide the development of the basket components into the field plan and the important basis for on-site installation. The content must be complete, in line with the actual situation of the project. Installation configuration table should be basket installation number, installation height, hanging device before and after reaching length, hanging platform length, installation form, with wire rope length and so on; Installation layout plan should be appropriate size, clear text, according to the proportion of drawing. Drawing on the surface of only different elevations on the installation site of the suspension device contour lines, labeling daughter walls, stairwells, elevators, patios, trenches at the elevation and installation of the main peripheral dimensions, and draw the site crane installation location and suspension device before and after the extension of the beams, weights of the schematic location. For the building elevation on the smaller size of the protruding and receding position should be locally enlarged drawing, so that the demonstration of experts, installers, users and all relevant management personnel in the layout plan can be a clear understanding of the suspension device is feasible to install, whether there is a centralized stacking of counterweights, suspension platform and the distance between the construction surface is in line with the operational requirements, as well as the safety rope layout and fixing method and other information. Basket program structure In order to make the special construction program clear, complete and operable, the program structure should be in line with the provisions of the Jianban quality [2018] No. 31, the preparation of the basic content:1, project overview
(1) project overview: project name, project address; the surrounding environmental conditions, Site conditions at the time of entry; floor area, maximum elevation, building roof and fa?ade shape; volume of work; expected construction period. Available list and related plans, elevations. (2) the parties involved in the construction: construction units, construction general contractors, construction units, specialized subcontracting units, supervision units and basket installation and maintenance units. (3 )Professional work content overview: the basket work object and construction scope of the overall introduction; need to bring material to lift the type of material, specifications, weight parameters and placement requirements; basket type and installation methods.2, the preparation of the basis
(1) survey and design documents: and the installation of hanging baskets related to architectural drawings, curtain wall installation project special construction program, special construction methods for external decoration. (2) laws and regulations and regulatory documents: the relevant content of the construction of the basket. State Council Decree No. 393 and provincial and municipal regulations. (3) technical standards: prioritize the citation of low standards, but can not violate the high standards and related laws and regulations. Commonly used are the following standards, regulations: "Crane Design Regulations" GB 3811 "Crane, wire rope maintenance, maintenance, inspection and scrapping" GB/T 5972 "Basket of work at height" GB/T 19155 "Building construction tool-type scaffolding safety technical regulations" JGJ202 "Construction lifting equipment and facilities inspection standards" JGJ 305 "Construction lifting equipment and facilities inspection standards" JGJ 305 "Construction lifting equipment and facilities inspection standards" JGJ 305 "Construction lifting equipment and facilities inspection standards" JGJ 305 "safety technical regulations for the use of construction machinery" JGJ 33 "building construction safety management specification" DB 33/1116 (4) construction unit management system documents3, the basket equipment description
Basket equipment information: basket manufacturer, factory year and month; basket model, the main technical parameters. Basket model, the main technical parameters; special installation form selection and structural characteristics, special design and components manufacturing enterprises.4, basket installation layout design
Drawing basket installation layout, prepare basket installation configuration table. Should be clear on-site lifting machinery installation location, indicating the net distance between the adjacent basket platform and suspension platform and elevator cage, list marked by the machine position using the basket specification model, platform length, installation height, suspension device installation type, beam outreach length, weight support before and after the spacing, the number of weights and other basic parameters and the number of special distribution box and installation location. The complexity of the building elevation should draw special parts of the construction of the basket section.5, the building structure supporting capacity verification
Calculation of the basket hanging device in the most unfavorable conditions, the maximum force exerted on the building supporting structure; (if any) pre-embedded parts or anchors related to the calculation; entrusted to the relevant units of the verification of the building structure of the local and the whole can withstand the action of the basket exerted force; (if necessary) to provide local or overall structural strengthening measures.6, special installation form of hanging basket safety requirements and measures
Provide design calculations and manufacturing enterprises to confirm the certificate; components production and acceptance requirements; structural type and characteristics, important nodes, installation location, use of the requirements and safety and technical measures and other detailed description.7, construction operation plan
Personnel organization plan, full-time safety management personnel and installation/dismantling of special operations and supporting construction staffing plan, materials and equipment entry plan, power supply and distribution plan, installation/dismantling construction progress plan.8, construction safety and technical measures
