The support frame 2 includes a main support rod 2.1 located at one end of the work platform 1 near the elevator shaft door opening, a diagonal support rod 2.2 located at the other end of the work platform, and a tie rod 2.3 for connecting the main support rod 2.1 and the diagonal support rod 2.2. The included angle α between the main support rod 2.1 and the work platform 1 is greater than 90°. The bottom of the support frame 2 is provided with a support leg 3 that overlaps with the elevator shaft door opening. This design of the support frame can maintain the work platform in a horizontal state while engaging with the elevator shaft door opening; simultaneously, after installation, the end of the work platform away from the elevator shaft door opening and the support leg share the load.

[0037] As attached Figure 1 To be continued Figure 3 As shown, the support plate 5 is movably mounted on the side of the bottom frame 1.1 near the elevator shaft door opening. The linear actuator 4 is located inside the bottom frame 1.1 and connected to the support plate 5. The linear actuator is used to push the support plate out and press it against the inner wall of the elevator shaft. Preferably, there are 1 to 2 linear actuators 4, and their push rods pass through the bottom frame 1.1 and are connected to the support plate. The linear actuator 4 is one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder. In specific implementation, after the construction platform is installed, the linear actuator can be used to push out the support plate and press it against the inner wall of the elevator shaft to form the internal support structure of the working platform. This allows the working platform to be internally supported against the inner wall of the elevator shaft, which can greatly reduce the stress on the support legs and improve the service life of the support legs during subsequent operations.

Figure 2 To be continued Figure 4 As shown, the support plate 5 also includes a top plate 5.3, which is located on top of the support plate body 5.1 and is used to contact the bottom surface of the elevator shaft door opening. The length of the top plate 5.3 is less than the width of the elevator shaft door opening. This design allows the top plate of the support plate to bear part of the vertical load, further reducing the stress on the support legs.

[0041] Preferred options are listed below. Figure 3 and attached Figure 4 As shown, the lengths of the support plate body 5.1 and the base plate 5.2 are equal, and the lengths of both are greater than the width of the elevator shaft door opening and less than the inner width of the elevator shaft.

[0042] Preferred options are listed below. Figure 2 As shown, the side of the support plate body 5.1 and the top plate 5.3 that contacts the elevator shaft door opening is also provided with a rubber pad 8, which has a good cushioning effect and anti-slip effect.

[0043] Preferred options are listed below.Figure 1 As shown in the drawings, the panel 1.2 located at the position of the linear actuator 4 on the work platform 1 is provided as a reversible open-close panel 1.2.1, facilitating the installation and maintenance of the linear actuator.
