The utility model discloses the safety class technical problem that will solve solves traditional construction method not enough, provides a preparation simply, and convenient and practical can overcome and repeatedly take and tear open the scaffold frame and cause the not enough of wasting of resources, can solve again because the untimely marginal potential safety hazard, safe and reliable's an operation platform that appears of PC stair installation.
In order to achieve the aim, the utility model adopts the following technical scheme that the PC staircase safety protection operating platform is characterized by comprising a support frame and a horizontal operating platform arranged on the support frame; an inclined plane is arranged below the supporting frame, and two ends of the inclined plane are respectively provided with a horizontal supporting surface; when the support frame is placed on the upper stair beam and the lower stair beam of each stair layer, the horizontal support surface is just abutted against the steps arranged on the edges of the stair beams for installing the PC stairs.
The supporting frame is of a regular triangle structure and is formed by welding a plurality of steel materials.
The horizontal supporting surface is formed by welding a plurality of steel materials, and holes are reserved on the horizontal supporting surface; when the support frame is placed between the upper stair beam and the lower stair beam, the embedded screws for fixing the PC stairs are respectively positioned in the holes to limit the support frame at the step positions of the upper stair beam and the lower stair beam. The steel is a square steel pipe.
And a hoisting mechanism for hoisting is arranged on the horizontal operation platform. The hoisting mechanism is a hoisting ring.
By adopting the operation platform, the problem of staircase safety protection is effectively solved, the operation platform required by staircase reinforcement and wall column formwork is solved, the resource waste caused by repeated mounting and dismounting of the conventional steel pipe filling frame is avoided, and the safety protection problem caused by delayed installation due to untimely supply of PC staircase materials is effectively prevented. The comprehensive results show that the operating platform has the characteristics of simple manufacture, convenient installation, safety, reliability and cost saving.

Detailed Description
The utility model provides an operation platform for solving PC stairwell safety protection problem, refers to fig. 1 and fig. 2, includes horizontal operation platform 1, and its material is thick decorative pattern steel sheet, and the steel sheet that adopts the decorative pattern material can be anti-skidding. The thickness of the horizontal operation platform can be enough to reach the supporting strength, and the horizontal operation platform cannot be too heavy, so that the hoisting and the bearing of the stair beam are influenced. And a hanging ring 11 is also welded on the horizontal operation platform and used for fixing a lifting rope during hoisting.
The horizontal operation platform is supported by the support frame 2. The lower inclined plane 3 of the supporting frame is a right-angled triangle structure in the embodiment, and the inclined plane is the hypotenuse of the right-angled triangle. The upper end and the lower end of the inclined plane are respectively provided with a horizontal supporting surface 4; when the support frame is placed on the upper stair beam and the lower stair beam of a first stair, the horizontal support surfaces at two ends of the inclined surface of the support frame just abut against the steps arranged on the edges of the stair beams for installing the PC stairs, and the upper surface of the horizontal operation platform is basically flush with the upper surface of the stair beam above.
The support frame is formed by welding square steel pipes, and the support frame and the horizontal operation platform are also welded. During manufacturing, attention needs to be paid to double-sided welding for welding square steel, the welding seam is full, the standard requirement of welding specifications is met, and potential safety hazards caused by the problem of welding quality are avoided; meanwhile, the welding size is accurate, the error is not allowed to exceed 50mm, the angle is accurate when the platform is installed, and the platform is tightly attached to the stair beam.
Because the whole square steel pipe welding that is formed of support frame, consequently, the support frame is frame construction, also is frame construction in horizontal holding surface 4 department, all keeps the space in the frame. Because the stair beam is a prefabricated one used for installing the PC stairs, the screw rod for fixing the PC stairs is also pre-embedded at the step for limiting for installing the PC stairs on the stair beam. The stair beam structure is a stair beam structure which is commonly used for installing a PC stair. When the support frame hoists to two stair girders of the one-storey building, which are located at the upper side and the lower side of the one-storey building and are provided with the PC stairs, the horizontal support surface on the inclined surface of the support frame not only just abuts against the step of the stair girder, but also is just located in the gap of the frame at the horizontal support surface. Through the cooperation in screw rod and space, prevent that the carriage from receiving when vibrations, taking place the displacement in stair roof beam department.
The operation platform solves the edge-facing potential safety hazard caused by installation lag of the PC stairs, and provides a reliable operation platform for formwork support of the next-floor stairwell. The specific operation method of the operation platform is as follows, referring to fig. 3, the floors are divided into three floors of N-2, N-1 and N as an example, suspended stair girders 5 and stair girders 6 are prepared in each floor in advance, and each stair girder is provided with a step 7 and a pre-buried screw 8.
(1) Before the N layers of structural steel bars are bound, the operation platform is manually hoisted at the positions of the N layers of floor stair girders 6 and the N-1 layers of the stair girders 6 by adopting a tower crane in a matching way, the upper horizontal supporting surface and the lower horizontal supporting surface of the supporting frame are respectively lapped and abutted against the steps of the stair girders 5 and 6 for limiting, and simultaneously, the pre-embedded screw is inserted into the gap of the frame at the horizontal supporting surface, so that the sliding phenomenon caused by construction vibration after the platform is installed is effectively avoided;
(2) workers can stand on a platform consisting of the stair beams and the operating platform and bind wall column reinforcing steel bars and wall column templates of N layers of staircases for installation; after the installation, pouring retarded soil, and after the pouring, standing a worker on a platform consisting of the stair beam and the operating platform to remove the wall column template;
(3) after the wall column template of the staircase is completely removed, the operation platform can be temporarily hoisted to the floor, and the PC staircases 9 with N-1 layers are installed;
(4) after the PC stairs are installed, hoisting the operation platform to the positions 5 and 6 of the top plate stair beams of the N layers, and repeating the operation of the step (1);
(5) if the PC stairs are not supplied timely and cannot be installed timely and other special conditions occur, the steps (3) and (4) can be changed into the steps of directly lifting the operation platform to the positions 5 and 6 of the top plate stair beams of the N floors to repeat the steps (1) and (2) in the operation
By adopting the operation platform, the problem of staircase safety protection is effectively solved, the operation platform required by staircase reinforcement and wall column formwork is provided, the resource waste caused by repeated mounting and dismounting of the conventional steel pipe filling frame is avoided, and the safety protection problem caused by delayed installation due to untimely supply of PC staircase materials is effectively prevented. The comprehensive results show that the operating platform has the characteristics of simple manufacture, convenient installation, safety, reliability and cost saving.
