Description

Technical Field

[0001] The utility model belongs to the technical field of elevator installation auxiliary equipment, and specifically relates to a rotatable elevator shaft operating platform. Background Art

[0002] In high-rise and super-high-rise buildings, the elevator shaft structure of residential buildings is basically a frame shear wall core tube structure. When constructing the elevator shaft, if traditional steel pipe scaffolding is used as the construction operation frame and formwork support frame, its overall rigidity is poor, and the stability and safety of the frame are poor. Pre-embedding work must be done before pouring concrete, and this step will cause great damage to the core tube structure.

[0003] The details are as follows:

[0004] (1) When constructing an existing elevator shaft, it is necessary to reserve openings in the shear walls on both sides and install I-beams before erecting the frame. Two I-beams need to be installed every four floors. At the intersection of the frame uprights and the I-beams, 150mm high steel bar heads are welded on the I-beams. Two steel pipes need to be embedded in the floor at the elevator door every two floors, and the steel pipes need to be connected to the frame, which requires more construction processes.

[0005] (2) During the construction process, the frame cannot be dismantled, and the installation of I-beams is cumbersome, causing a large number of holes in the elevator shaft structure. When the frame is dismantled later, welders are required to cut the embedded parts when removing the I-beams; after the I-beams are removed, the embedded holes need to be repaired, which is a large workload and causes much damage to the elevator shaft structure. The cut I-beams cannot be reused.

[0006] In addition, the traditional scaffolding system has some disadvantages such as long erection period, more construction materials and higher erection cost.

[0007] Therefore, there is a need for an elevator shaft operating platform that is easy to install and disassemble, can be turned around, and has high utilization efficiency to solve the above problems. Utility Model Content

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0024] As shown in the figure, the utility model describes a rotatable elevator shaft operating platform, including a horizontal top frame 1, a vertical support frame 2 and a diagonal brace 3 forming a right-angled triangle structure, a steel pipe 5 is laid above the horizontal top frame 1 through an I-beam 4, the steel pipe is welded to the I-beam, a wooden square is provided above the steel pipe 5, and hooks 6 are provided on both sides of the horizontal top frame 1, and a movable supporting foot frame 7 is provided below the vertical supporting frame 2, and the supporting foot frame 7 includes a short vertical steel 8 and a short flat steel 9, and the short vertical steel 8 and the short flat steel 9 are set at 90°. After installation and fixation, the short vertical steel 8 and the vertical support frame 2 are on the same vertical line, the short flat steel 9 as a whole is on the same axis with the diagonal brace 3, and the lower plane of the short flat steel 9 is in a horizontal state.

[0025] The utility model describes a rotatable elevator shaft operating platform. The right-angled triangle structure must meet the size requirements of the core tube inside the elevator shaft. Before installation, the area around the elevator shaft must be kept clean and tidy. Hoisting can be carried out after there are no construction workers in the elevator shaft. When the strength of the next layer of concrete reaches the corresponding requirements, the operating platform is slowly placed into the shaft by a hoisting machine. The short flat steel 9 is placed horizontally on the crossbeam at the elevator shaft opening and fixed. The lower plane of the short vertical steel 8 is located on the outside of the side of the floor at the elevator shaft door opening. The side of the operating platform is fixed to the elevator shaft to prevent it from tipping over to the side. The overall structure is a triangular structure that is not easy to shake. An isolation layer is laid on the wooden square to make the surface of the operating platform flat, easy to construct and safe. If it needs to be hoisted upwards, loosen the pin 10 of the supporting footrest 7, and rotate it so that the outside of the short flat steel 9 is in a vertical state, such as Figure 3 As shown, in order to facilitate lifting, after the operating platform is transferred to the upper level, the protection of the door opening of the lower stairwell must be in place in time, and the door opening of each level must be protected.
