Abstract

The invention discloses a scaffold with a hemispherical structural surface and an erection method thereof. The scaffold comprises a plurality of stress cones, and further comprises a plurality of rowsof scaffold vertical rods; two rows of arc-shaped steel pipes are arranged on the outer wall, at each row of stress cones, of a concrete structure and are fixed on the outer wall of the concrete structure through locking screws together with fastening base plates; the outer walls of the lower ends of each row of scaffold vertical rods are connected to the outer walls of the corresponding arc-shaped steel pipes through fasteners; a longitudinal horizontal rod is arranged between every two adjacent scaffold vertical rods in each row of scaffold vertical rods; and transverse horizontal rods which are perpendicular to the longitudinal horizontal rods and the scaffold vertical rods are erected at the upper parts of the longitudinal horizontal rods. The scaffold with the hemispherical structural surface has the advantages that the problem of erection of an operation platform in the construction process of a spherical structure can be solved, and a safe and reliable operation platform and anerection method are provided for the construction of a similar structure.

Description

Technical field

[0001] The invention relates to a scaffold, in particular to a scaffold with a hemispherical structure surface and a erecting method thereof. Background technique

[0002] The nuclear power plant reactor building is the third barrier for radioactive containment, used to prevent the release of radioactive materials to the environment during normal operation and accidents. Under normal operating conditions and accident conditions, radiation protection is provided for on-site personnel, while protecting the internal systems of the reactor building from external disasters. The containment is a reinforced concrete tube structure, including the tube body and the hemispherical dome. During the construction and installation of the containment, the conventional pylon platform is suitable for the cylinder structure, and the spherical structure of the dome cannot be hung. There is no operating platform for on-site construction, and the safety risk during the construction pr...

Examples

Embodiment 1

[0032] Such as figure 1 , figure 2 with image 3 As shown, a scaffold with a hemispherical structure surface of the present invention and its erection method include a plurality of force-bearing cones 1 embedded in the hemispherical concrete structure 14 in order from bottom to top along the hemispherical surface of the hemispherical concrete structure. Multiple rows of force cones 1, each row of force cones 1 are evenly arranged along the horizontal circumferential direction of the concrete structure, and each force cone 1 is arranged along a direction parallel to the radial direction of the concrete structure and its end points In the center of the concrete structure, there are two rows of arc-shaped steel pipes 2 on the outer wall of the concrete structure along the circumferential direction at 1 of each row of force cones. A locking screw 3 is arranged between the two rows of arc-shaped steel pipes. One end is inserted into the force cone 1, the other end of the locking sc...

Embodiment 2

[0040] A method for erecting a scaffold with a hemispherical structure surface includes the following steps:

[0041] S1: Determine the erection spacing of each component and scaffold according to the load design;

[0042] S2: Pre-bury multiple rows of force cones in the concrete structure according to the hoop, longitudinal, and transverse spacing determined in S1;

[0043] S3: After the construction of the concrete structure is completed, the force cone is cleaned, and the supporting member is installed on the bottom row of the accepting cone through the locking screw, and the outer surface circumference of the concrete structure at each remaining row of the force cone Install two rows of arc-shaped steel pipes, one end of the locking screw passes through the two rows of arc-shaped steel pipes to connect with the stressed cone, and the other end is sleeved with a fastening pad to fasten the arc-shaped steel pipes to the outer wall of the concrete structure;

[0044] S4: Lay the bott...
