Description

A prefabricated elevator shaft operating platform

technical field

The utility model belongs to the technical field of operating platforms in construction engineering, and in particular provides a prefabricated elevator shaft operating platform.

Background technique

In construction, the elevator shaft operation platform mostly uses the wall to leave holes to build scaffolding. This method has the disadvantages of poor mechanical performance and stability caused by the lack of vertical poles, and there are certain potential safety hazards, and the scaffolding is labor-intensive and material-intensive.

Utility model content

The purpose of the utility model is to provide a prefabricated elevator shaft construction platform, which solves the problems of poor mechanical performance and poor stability caused by setting up scaffolds with holes left in the wall. Made of channel steel, the structure and manufacture are simple, the installation and construction are convenient, turnaround, and repeated use can improve efficiency, ensure safety, and reduce construction costs.

The utility model comprises: a platform frame 1, a frame leg 2, a frame leg oblique support 3, lifting lugs 4, and a platform panel 5. Frame leg 2 is welded vertically to one side of platform frame 1, one end of frame leg slant support 3 is welded to the bottom 100mm of frame leg 2, the other end is welded to the opposite side of the connecting side of platform frame 1 and frame leg 2, and lifting lug 4 is connected to platform frame 1 The four corners are welded vertically. The platform panel 5 is welded to the platform frame 1 . The components are connected to form a whole elevator shaft operation platform.

First, according to the actual length and width of the elevator shaft, cut the 14# channel steel 5cm shorter than the actual size of the elevator shaft. Combine them into a rectangular skeleton by vertical welding connection, weld three horizontal 14# channel steel supports in the middle of the platform skeleton to form platform skeleton 1; then cut two 14# channel steels with the same length as the floor height. Two 14# channel steels are welded and connected by 12# channel steels, the width of which is 20cm shorter than the width of the elevator shaft door opening, and the distance between 12# channel steels is 500mm. 14# channel steel with a length of 150mm is vertically welded at 100mm at one end of two 14# channel steels respectively. Weld and fix with triangular brackets to form frame legs 2; then cut two pieces of 14# channel steel, the length of which is the length of the hypotenuse of the triangle formed by the depth of the elevator shaft and the height of the floor, which is the diagonal support 3 of the frame legs; then use no less than 8mm thick A steel plate with an inner diameter of 50mm is used to make the lifting lug 4; a 5mm thick steel plate is used to cut the platform panel 5 according to the actual size of the elevator shaft.

The utility model has the advantages of simple manufacture, flexible and convenient operation, good stress performance and stability, saving safety time, time and labor, high work efficiency and saving construction cost.

detailed description

The utility model comprises: a platform frame 1, a frame leg 2, a frame leg oblique support 3, lifting lugs 4, and a platform panel 5. Frame leg 2 is welded vertically to one side of platform frame 1, one end of frame leg slant support 3 is welded to the bottom 100mm of frame leg 2, the other end is welded to the opposite side of the connecting side of platform frame 1 and frame leg 2, and lifting lug 4 is connected to platform frame 1 The four corners are welded vertically. The platform panel 5 is welded to the platform frame 1 . The components are connected to form a whole elevator shaft operation platform.

In order to further understand the invention content, characteristics and effects of the present utility model, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Step 1: First, weld the platform frame 1, frame legs 2, frame leg oblique supports 3, lifting lugs 4, and platform panels 5 according to the position of the design drawing, which are made according to the actual length and width of the elevator shaft and the height of the floor.

The second step: then pass the lifting lug 4 through the steel wire rope on the tower crane, hoist it to the top of the elevator shaft, and drop it vertically and uniformly in the completed elevator shaft, so that the frame legs 2 are located on the floor at the door of the completed elevator shaft, as Support points to support the entire operating platform. After checking the safety, release the wire rope of the tower crane.

Step 3: After the construction of the operation floor is completed, that is, the inner formwork of the elevator shaft is removed, and then the wire rope on the tower crane passes through the lifting lug 4 to lift the prefabricated operation platform to the previous floor.
