In the prior art, the building structure is usually a single concrete structure, and compared with the structure made of other materials, the building structure has better integrity, can be poured into a whole, has better mouldability, can be poured into structures with various shapes and sizes according to different requirements of construction, and has durability and fire resistance as well as lower manufacturing cost and maintenance cost. However, in construction and practice, the disadvantages of complex construction process and long construction period are also exposed.
Under the prior art, the reinforced concrete large-section frame beam is also used as a construction mode of a basic beam of the lifting equipment, and is widely accepted and applied due to the characteristics of short construction period, economy, durability, safety, reliability and the like. The job site needs more large-scale construction equipment usually, under prior art, large-scale equipment's transportation and installation all need consume a large amount of manpowers, and in the construction of high-rise building, construction equipment's promotion and location also become comparatively numerous and diverse problem, generally, under prior art, large-scale equipment can only install at the earth's surface, and must support single equipment foundation, in high-rise building, adopt manpower or the lifting means who establishes in addition to the equipment that can carry usually to transport, and can only carry out the construction back on the earth's surface basis to the equipment that can't transport, promote the transport again, such construction mode space limitation is great, and waste time and energy, in addition factor of safety in the high altitude transportation also is difficult to obtain the guarantee. And the reinforced concrete large-section frame beam also serves as a construction mode of a basic beam of the lifting equipment, and can be installed on the frame beam with any designed height through hoisting, so that the limitation to the space in the traditional construction mode is effectively overcome. In the existing mode, a large-diameter sleeve is pre-buried in a reinforced concrete frame beam, then large equipment can be arranged and mounted on the pre-buried large-diameter sleeve after being hoisted, and the large equipment can also be mounted and lifted at any height, so that the construction mode that the frame beam replaces a single earth surface foundation is realized, the construction flow is greatly simplified, and the internal consumption phenomenon in subsequent engineering is effectively relieved.
