Laminated precast concrete lift shaft connecting device

Abstract

A laminated precast concrete lift shaft connecting device comprises a floor plate, a floor beam, an extruded sheet, a corrugated pipe, a steel reinforcement, a grouting material, an upper section of precast lift shaft, a lower section of precast lift shaft and mortar; the extruded sheet is placed between the upper section of precast lift shaft and the floor beam in the upper layer; the corrugatedpipe is placed at the top of the upper section of precast lift shaft and the bottom of the floor beam in the upper layer; the steel reinforcement is placed in the corrugated pipe; the grouting material is placed in the corrugated pipe; the mortar is placed between the upper section of precast lift shaft and the lower section of precast lift shaft and between the lower section of precast lift shaftand the floor plate; and the upper section of precast lift shaft and the lower section of precast lift shaft are fixedly connected with each other, and the lower section of precast lift shaft and thefloor beam are fixedly connected with each other. The laminated precast concrete lift shaft connecting device has the advantages that the process is simple, the mounting is convenient and fast, the quality is reliable, only a small quantity of wet operations are on site, construction wastes cannot be generated, each requirement of an assembled building is satisfied and so on.

Description

technical field [0001] The invention relates to a stacked precast concrete elevator shaft, in particular to a stacked precast concrete elevator shaft connection device. Background technique [0002] With the continuous improvement of my country's economic level and construction level, more and more multi-storey, high-rise and super high-rise buildings have appeared, and elevators are indispensable equipment. Many high-rise buildings often use frame, frame-shear wall and other structural systems, and elevator shafts in frame, frame-shear wall and other structures are generally formed by bricklaying or prefabricated wall panels on the floor beams (using existing Except for pouring concrete load-bearing shear walls that also serve as wells), the use of brick wells or prefabricated wall panels has the following disadvantages: ① Brick elevator wells have many procedures, labor and time, and human factors are greatly affected, and the quality is difficult to guarantee. ② The bric...
