[0003] The traditional elevator shaft construction platform adopts a floor-standing steel pipe fastener scaffolding platform, which takes a long time to set up and requires a lot of manpower and material resources. As the height of the scaffolding increases, the bracket becomes more unstable, posing a greater safety hazard; at the same time, the workload and quality of the I-beam openings and wall connection openings are not up to standard, resulting in uneven exterior walls and water leakage in the later stage; the handover of the elevator shaft is delayed. The non-floor-standing elevator shaft construction platform includes an upper load-bearing platform and a lower supporting member. The supporting member includes a vertical keel and a horizontal crossbar. The vertical keel is vertically fixed under the load-bearing platform, and a horizontal crossbar is set at the bottom of the vertical keel. Since the dimensions of the load-bearing platform in all directions are smaller than the corresponding dimensions of the elevator shaft, when in use, the horizontal crossbar is supported at the lower elevator shaft opening, and the end of the load-bearing platform away from the upper elevator shaft opening is against the shaft wall of the elevator shaft, causing the load-bearing platform to tilt to a certain extent.

For example, the vertical micro-tilt keel 21 and the oblique keel 22 are both made of 10# I-beam, and the crosspiece 23 is made of 16# I-beam.

[0032] The multi-purpose steel platform for the elevator shaft provided in the embodiment of the present application has the following advantages: 1. When constructing the main structure of the H layer, the crosspiece 23 of the supporting member 2 is fixed on the H-2 layer, the load-bearing platform 1 is on the H-1 layer, and the operating frame 3 is installed on the load-bearing platform 1. The operator constructs the H layer on the operating frame 3; after the construction of the main structure of the H layer is completed, the operating frame 3 is lifted off the elevator shaft 4, and the load-bearing platform 1 and the supporting member 2 are lifted down one layer, so that the top surface of the load-bearing platform 1 is lifted to the H-2 layer. At this time, the template of the H-2 layer reaches the removal condition, and the load-bearing platform 1 can be temporarily 1. As an unloading platform, the formwork, steel pipes, wooden beams and other construction materials 5 are transported to the load-bearing platform 1, and lifted to the material yard in time for maintenance and turnover; 2. Through the design of the vertical slightly inclined keel 21 at an obtuse angle to the load-bearing platform 1, when the cross bar 23 is supported on the H-2 floor elevator shaft opening and the end of the load-bearing platform 1 away from the H-1 floor elevator shaft opening is against the shaft wall of the elevator shaft 4, the horizontality of the load-bearing platform 1 can be ensured as much as possible, thereby ensuring the verticality of the operating frame 3 installed on the load-bearing platform 1, reducing the risk of the operating frame 3 tipping over, and improving the construction safety factor.

[0033] In this embodiment, the load-bearing platform 1 includes a load-bearing main keel 11, a load-bearing secondary keel 12 and a load-bearing steel plate 13.

In this way, by setting a double triangular keel structure (the vertical micro-tilt keel 21 and the oblique keel 22 each include two), the structural strength and stability of the support member 2 are improved; by setting a cross brace 25 between the triangular keel structures, the structural strength and stability of the support member 2 are further improved.

[0039] In this embodiment, the support member 2 further includes a diagonal brace 26, one end of which is connected to the upper side of the crosspiece 23, and the other end is connected to the vertical slightly tilted keel 21. Exemplarily, the diagonal brace 26 is made of No. 16 I-beam, and is connected to the vertical slightly tilted keel 21 and the crosspiece 23 by welding.
