Problems solved by technology

However, even the local scaffold construction method needs to build a scaffold with a height equivalent to the highest point of the cylindrical reticulated shell. For extra large and super high cylindrical reticulated shells, the construction cost and construction difficulty are still relatively large

Embodiment Construction

[0014] As shown in the accompanying drawings, the method for installing a large-span cylindrical reticulated shell according to the present invention is characterized in that it includes the following steps:

[0015] A) The large-span cylindrical reticulated shell is divided into multiple mesh arches arranged in the axial direction in combination with the support situation, and each mesh arch belt includes at least four supports 1 symmetrically arranged on both sides and installed on the four A support 1 is connected to each other into grid-shaped ball joints and pull rods; first a mesh arch is installed, and this first installed mesh arch is called the mother arch. Both sides of the mother arch in the present embodiment have Two bearings 1, one movable ball joint 2 is respectively installed on the bearing 1 on either side of the mother arch. The movable ball joint 2 is installed on the support 1 in a manner that can rotate and the position of the center of the ball cannot be ...

Abstract

The invention relates to a method for constructing and mounting a wide-span cylindrical reticulated shell structure, in particular to a method for mounting a wide-span cylindrical reticulated shell. In the process, a mother arch is installed on the ground by a bulk method at first, and the construction is gradually boosted from one side of the mother arch to the other side during installation; and the extending tail end of the mother arch is lifted by matching lifting equipment so that the height of the extending tail end is always suitable for the requirement of the installation and construction of the ground. After the mother arch is installed, the construction is carried out by a high-altitude cantilevered method and extends and boosts along the axial direction of the mother arch, and other reticulated arches which are adjacent to the mother arch are sequentially installed till the installation of the whole wide-span cylindrical reticulated shell is finished. The installation process uses the lifting equipment, such as hoists, and the like as accessory appliances without erecting a scaffold, is simple and practical and has high reliability, low cost and short construction period.

Description

technical field [0001] The invention relates to a construction and installation method for a large-span cylindrical reticulated shell structure, in particular to a method for installing a large-span cylindrical reticulated shell. Background technique [0002] The dry coal shed of the thermal power plant usually has a static span of more than 76 meters due to the coal pouring machine process, and some even exceed 110 meters, and its net height is generally more than 28 meters. The scientific, economical and reasonable solution for this large-span and high-height closed shed is to adopt a cylindrical reticulated shell structure, which has been verified by mathematical and mechanical theoretical calculations. However, its installation process has been constantly changing and discussing. Using different installation techniques will result in different costs and construction periods, with different effects. The traditional construction technology is divided into overall scaffol...
