Construction technology for protecting tool type elevator shaft installed on front vertical face without disassembly and change

Abstract

The invention discloses a front facade installation tool type elevator shaft protection construction process without disassembly and change, which comprises the following steps: after a protection frame and a hard isolation layer are erected in a shaft, firstly drilling holes in the inner side of the wall of the shaft, then installing a steel plate with holes, and finally welding a round pipe. And a round pipe is welded on a crosspiece on the protective fence door and is conveyed to a mounting position. The short end of the connecting piece is inserted into the round pipe of the rear steel plate, the long end with the thread is inserted into the round pipe of the upper crosspiece of the protective fence door, and the nut is screwed down. When an elevator front room is decorated, the lower crosspiece of the protective fence door is heightened, so that the distance between the protective fence door and the outer side face of the shaft wall has the requirement for decoration operation. Before construction of the elevator front room terrace, the cushion block below the lower crosspiece of the protective fence door is pulled out, so that the distance required by terrace construction is reserved between the lower crosspiece of the protective fence door and the terrace surface, and the lower crosspiece of the protective fence door is tightly attached to the decoration finished surface; and the lower crosspiece of the protective fence door is lifted backwards and upwards, so that a gap convenient for garbage cleaning is formed between the lower opening of the lower crosspiece and the elevator shaft wall.

Description

technical field [0001] The invention relates to a construction process for a tool-type elevator shaft protection installed on the front facade that does not need to be dismantled and modified, in particular to a construction process of the tool-type elevator shaft protection installed on the front facade without the need for removal and modification, and in particular to a tool type elevator shaft protection installed on the outer side of the elevator shaft During the decoration and the construction of the elevator front room floor, the construction process can be completed as long as the elevator shaft protective fence door is slightly changed, such as padding. Background technique [0002] With the development of building construction technology and the variety of human needs, various reinforced concrete buildings with elevators have sprung up like mushrooms after a rain. [0003] In the stage of organizing the implementation of reinforced concrete buildings, the protectio...
