Problems solved by technology

[0003] The technical problem to be solved by the present invention is that during the construction and installation of the containment, the conventional hanger platform is suitable for the shell structure, but it cannot be hung for the spherical structure of the dome, and there is no operating platform for the on-site construction, and the safety risk is extremely great during the construction process. The purpose is to provide A hemispherical structural surface scaffolding and its erection method, which can solve the problem of erecting an operating platform during the construction and installation of a spherical structure, and provide a safe and reliable operating platform and an erecting method for construction of similar structures

Embodiment 1

[0032] Such as figure 1 , figure 2 and image 3 As shown, the present invention has a hemispherical structural surface scaffolding and its erection method, including a number of stress cones 1 pre-embedded in the hemispherical concrete structure 14, which are sequentially arranged along the hemispherical surface of the hemispherical concrete structure from bottom to top Multiple rows of stress cones 1, each row of stress cones 1 are evenly arranged along the horizontal circumferential direction of the concrete structure, each stress cone 1 is arranged along a direction parallel to the radial direction of the concrete structure and the end points to In the center of the concrete structure, two rows of arc-shaped steel pipes 2 are laid on the outer wall of the concrete structure at one place of each row of force-bearing cones along the circumferential direction, and a locking screw 3 is arranged between the two rows of arc-shaped steel pipes 2, and the locking screw 3 One end...

Embodiment 2

[0040] A method for erecting a scaffold with a hemispherical structural surface, comprising the steps of:

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

[0042] S2: Pre-embed multiple rows of stressed cones in the concrete structure according to the circumferential, longitudinal and transverse erection distances determined in S1;

[0043] S3: After the construction of the concrete structure is completed, the stress cones are cleaned, and the support members are installed on the bottom row of acceptance cones through locking screws, and the outer surface circumference of the concrete structure at the rest of each row of stress cones Install two rows of arc-shaped steel pipes, one end of the locking screw passes between the two rows of arc-shaped steel pipes and connects with the stressed vertebral body, and the other end is set with a fastening plate to fasten the arc-shaped steel pipes to the outer wall of the concr...

Abstract

The invention discloses a hemispherical structural surface scaffolding and its erection method, which comprises a plurality of stressed cones, two rows of arc-shaped steel pipes are arranged on the outer wall of the concrete structure at each row of stressed cones, and the two rows of arc-shaped steel pipes pass through locks. The tight screw and the fastening backing plate are fixed on the outer wall of the concrete structure, and it also includes multiple rows of scaffolding poles. The outer wall of the lower end of each row of scaffolding poles is connected with the outer wall of the arc-shaped steel pipe through fasteners. There are two adjacent scaffolding poles in each row. A longitudinal horizontal bar is arranged between the scaffolding poles, and a horizontal horizontal bar perpendicular to both the longitudinal horizontal bar and the scaffolding pole is set above the longitudinal horizontal bar. The hemispherical structural surface scaffolding of the present invention can solve the problem of setting up the working platform in the construction and installation process of the spherical structure, and provide a safe and reliable working platform and setting up method for the construction of similar structures.

Description

technical field [0001] The invention relates to a scaffold, in particular to a scaffold with a hemispherical structural surface and an erection method thereof. Background technique [0002] The reactor building of a nuclear power plant is the third barrier of radioactive containment, which is used to prevent the release of radioactive materials to the environment during normal operation and accidents. Under normal working conditions and accident conditions, provide radiation protection for on-site personnel, and at the same time protect the various systems inside the reactor building from external disasters. Its containment is a reinforced concrete cylinder structure, including the cylinder body and the hemispherical dome. During the construction and installation of the containment, the conventional hanger platform is suitable for the shell structure, but it cannot be hung for the dome spherical structure, and there is no operating platform for on-site construction, so the ...
