Elevator steel structure hoistway guide rail fixing device and construction method

Abstract

The invention discloses an elevator steel structure hoistway guide rail fixing device and a construction method. The elevator steel structure hoistway guide rail fixing device comprises a guide rail bracket, the guide rail bracket is fixedly connected with a steel structure hoistway through a guide rail bracket connecting arm, guide rails are arranged on one side of the guide rail bracket towardsthe inner side of the steel structure hoistway, the elevator steel structure hoistway guide rail fixing device also comprises a limiting plate group, the limiting plate group is installed on the guiderail bracket, the limiting plate group can limit the lateral displacement of the guide rails, and the guide rails can move vertically relative to the limiting plate group and be fixed at any positionin the vertical direction through the limiting plate group. According to the elevator steel structure hoistway guide rail fixing device and the construction method, the lateral displacement of the guide rails is limited through a guide rail horizontal positioning plate and the guide rail bracket after the position and perpendicularity of the guide rails are adjusted well, so that the later construction and calibration accuracy is improved; and in addition, the locking of the guide rails is realized through a guide rail pressing plate after the adjacent guide rails are aligned, so that it is ensured that the guide rails can not slide in the vertical direction after alignment, the whole adjustment process is very convenient, the relative positions of the guide rails can be adjusted when theguide rails are preassembled in a factory, the construction efficiency is improved and manpower and material resources are saved.

Description

technical field [0001] The invention relates to elevator construction technology, in particular to a guide rail fixing / pre-installation device for an elevator steel structure shaft, and a fast and accurate elevator steel structure shaft construction method realized by using the guide rail fixing / pre-installation device. Background technique [0002] The support of the elevator mainly depends on the elevator steel structure shafts connected to each other between the floors. The general elevator steel structure shafts are the steel structure frames fixed in the floors. According to past experience, most of the existing elevator steel structure shafts are quadrilateral Frame structure. In addition, the elevator can slide up and down along the elevator steel structure shaft mainly by using the guide rails in the steel structure shaft. Therefore, the installation position of the guide rails and the verticality of the guide rails directly affect the operation reliability of the ele...

[0002] The support of the elevator mainly depends on the elevator steel structure shafts connected to each other between the floors. The general elevator steel structure shafts are the steel structure frames fixed in the floors. According to past experience, most of the existing elevator steel structure shafts are quadrilateral Frame structure. In addition, the elevator can slide up and down along the elevator steel structure shaft mainly by using the guide rails in the steel structure shaft. Therefore, the installation position of the guide rails and the verticality of the guide rails directly affect the operation reliability of the elevator;

[0003] In addition, since buildings with high floors are generally constructed in sections during elevator construction, they need to be transported to the construction area after the steel structure shaft of the elevator leaves the factory, and then the construction personnel will calibrate and install the adjacent steel structure shaft of the elevator. During construction and installation, the guide rails must be aligned, but in actual construction, it often happens that the guide rails and even the entire steel structure shaft cannot be aligned, or even if they can be aligned, the construction personnel will consume a lot of manpower and material resources. Therefore, The more traditional construction methods in the existing technology, which mainly use hoisting and manual calibration, can no longer meet the requirements of elevator construction at this stage
