technical field

The utility model relates to the technical field of building template construction, in particular to an adjustable several-shaped telescopic beam for a formwork.

Background technique

In order to reduce the consumption of energy and resources and slow down the damage to the environment, the Chinese government followed the world trend and promulgated the "Green Building Evaluation Standard" in early 2006, followed by the "Green Construction Guidelines" to actively promote green building construction. Building construction takes a very short time in the entire building life, but its impact on the environment is great, and the consumption of resources and energy is also very concentrated. Therefore, to create a green building, green construction must be implemented. Green construction refers to construction activities that save resources and reduce negative impacts on the environment to the greatest extent through scientific management and technological progress under the premise of ensuring basic requirements such as quality and safety, so as to achieve energy saving, land saving, and water saving. , the four sections of material saving and environmental protection. In building construction, formwork and scaffolding have been widely used as a recyclable turnover material and machine tools. Therefore, the basic requirements that the building formwork system must meet under the requirements of green construction are: ① consume as little energy as possible; ② cause no or minimal harm to the environment; ④ When it is expected to be discarded, it should be reasonably harmless treated and recycled as resources; ⑤ At the current stage, the manufacturer must have a reliable recycling system that can ensure the realization of the above requirements, or guarantee that the product Complete harmless degradation can be achieved in nature.

In the "Green Construction Guidelines", templates and scaffolding are used as turnover materials and tools, emphatically emphasizing: ① should choose durable, easy maintenance and disassembly turnover materials and tools; Carry out formwork engineering construction; ③ formwork should be based on the principle of saving natural resources, and promote the use of shaped steel molds, steel frame bamboo molds, and bamboo plywood; ④ the formwork project plan should be optimized before construction. Multi-storey and high-rise buildings use reusable formwork systems, and formwork supports should be supported by tools; ⑤ optimize the external scaffolding scheme of high-rise buildings, and adopt schemes such as overall lifting and segmental overhang; 6. Promote the use of external wall insulation boards instead of concrete Construction formwork technology; ⑦ Take effective technical and management material-saving measures to increase the turnover times of formwork and scaffolding; 8. Vigorously develop the research and application of fair-faced concrete construction technology and new formwork and scaffolding technology. The main problem in existing formwork construction is that the size of the formwork is fixed, resulting in low applicability. Second, the size-adjustable formwork that has appeared recently has a complex structure, high manufacturing costs, and high technical requirements for on-site construction. Therefore, there is an urgent need for a low-cost formwork. , Simple structure, flexible and adjustable according to the needs of the new type of formwork with adjustable several-shaped telescopic beams, to meet the requirements of green construction.
