Prefabricated light concrete elevator shaft module with steel keel and manufacturing method thereof

Abstract

The invention provides a prefabricated light concrete elevator shaft module with a steel keel and a manufacturing method thereof. The prefabricated light concrete elevator shaft module comprises the light steel keel, wall surface sealing layers, a filling layer, a connecting box fixed to the inner side of the lower end of the light steel keel and embedded bolts fixed to the upper end of the light steel keel; the light steel keel is provided with an upper end face framework with embedded bolt holes, a lower end face framework with a connecting box, a longitudinal framework used for fixing the wall surface sealing layers and a transverse framework used for transverse connection; the wall surface sealing layers are non-dismantling formworks fixed to the inner surface and the outer surface of the module and located on the light steel keel; and light concrete is poured into a cavity formed between the inner wall surface sealing layer and the outer wall surface sealing layer, and the prefabricated module is formed through maintenance. By means of the prefabricated light concrete elevator shaft module, a modularized elevator shaft assembled on site can be formed. The prefabricated light concrete elevator shaft module has the beneficial technical effects that construction is safe and convenient, the construction period is short, the weight of the module is small, the construction cost is low, and the comprehensive performance is good.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an elevator installation project after an old building, and in particular to a prefabricated light concrete elevator shaft module with a steel keel and a manufacturing method thereof. Background technique [0002] The multi-storey buildings built from the 1950s to the 1990s did not have elevator equipment. As the population in these multi-storey buildings ages, daily going up and down stairs makes the elderly daunting. For those who are weak or need to use wheelchairs Residents, travel is even more difficult. [0003] As the city enters the deep aging process, people's demand for a better life continues to increase. The installation of elevators in multi-storey housing has become a major "just need". The gage is large. [0004] When installing elevators in old-fashioned residences, the elevator shaft can only be reinstalled on the outside of the outer wall. The tradition...

Problems solved by technology

[0004] When installing elevators in old-fashioned residences, the elevator shaft can only be reinstalled on the outside of the outer wall. The traditional method is to use steel structure elevator shafts for on-site assembly or cast-in-place concrete elevator shafts. Steel structures are easy to construct but have poor thermal insulation performance. The heat is good, but the on-site construction period is long, and the weight of the concrete well is high and the cost is high
