Building construction elevator shaft protection structure and construction method

Abstract

The invention discloses a building construction elevator shaft protection structure and a construction method, and belongs to the technical field of building construction. The structure comprises a floor slab in which floor slab steel bars are distributed, and the floor slab steel bars extend into a hole of an elevator shaft to form a steel bar protection layer; the steel bar protection layer is of a protection structure formed by transverse steel bars and / or longitudinal steel bars penetrating through the hole of the elevator shaft; and the transverse steel bars and the longitudinal steel bars which are arranged side by side within the range of the opening of the elevator shaft penetrate through the opening of the elevator shaft at the interval of one steel bar respectively. According tothe building construction method, when the steel bars are poured and arranged on a floor slab, the steel bars of the floor slab extend to penetrate through the hole of the elevator shaft, and the steel bar protection layer is formed in the hole. According to the building construction method, the elevator shaft can be sealed and protected in the floor slab steel bar construction stage, no extra installation in the later period is needed, extra labor and material cost is basically not generated, therefore the safety protection is achieved, the falling risk of operators during additional installation cost installation is avoided, and the method is essentially different from an existing elevator shaft safety protection method.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to the protection construction technology for the entrance of an elevator shaft in a high-rise building, and more specifically relates to a construction elevator shaft protection structure and a construction method. Background technique [0002] In building construction, the elevator is an important part of the building, and the height of the building determines the vertical depth of the elevator shaft. Therefore, the protection of the elevator shaft has always been one of the key safety concerns. However, due to the deficiencies in the protection of elevator shafts, accidents of people falling often occur. At present, most of the protection of elevator shafts is to add protective fences at the entrance of the door opening. This is a very imperfect protective measure. It cannot be guaranteed that people will not fall during the construction process, so there is no guaran...

Problems solved by technology

[0006] The invention provides a protective structure for elevator shafts in building construction, and its purpose is to solve the problems that safety accidents are likely to occur when the elevator shaft is open in the construction of high-rise buildings, but the existing protective measures require additional installation, the cost is relatively high, and there are risks in disassembly and assembly.
