Problems solved by technology

From the perspective of construction methods, both methods have higher requirements on the site. The bulk method requires that there should be no facilities within the length of the grid, otherwise hoisting and assembly operations cannot be carried out. The tire frame moving method requires the installation of the tire frame Therefore, both methods will affect the normal operation of all construction or production facilities in the grid area, resulting in disadvantages such as slow construction progress and long construction period.

Embodiment Construction

[0024] The present invention takes the following steps to carry out:

[0025] a. An operation platform 1 with a steel structure frame is erected at one end of the longitudinal axis of the grid structure outside the area covered by the grid structure. The outer contour of the operation platform 1 matches the lower surface of the grid structure 3, and the width of the operation platform 1 is the width of a small unit grid;

[0026] b. Lay the sliding track 2 along the length direction of the grid structure on the top surface of the independent foundation on both sides of the installation grid structure 3, and lay the sliding track 2 on the outside of the operating platform 1 at the same time, so that the sliding on the outside of the operating platform 1 The track 2 is connected with the sliding track 2 on the top surface of the independent foundation;

[0027] c. Use a crane to lift the grid material of the assembled grid structure 3 to the operation platform 1, install the su...

Abstract

The invention provides a large roof grid structure assembling and installing method, and belongs to the technical field of high-altitude and large-span grid structure installing methods. The method is used for assembling and installing a large roof grid structure. An operation platform is arranged outside a grid structure coverage area, grid structure assembling work is conducted on the operation platform, the assembled grid structure slides and is assembled through sliding rails, sliding power is provided through a hydraulic crawl device, and the grid structure can slide in place on the premise that the overall stability of the grid structure is kept. The large roof grid structure assembling and installing method is scientific and reasonable in design and easy and convenient to implement, construction quality is ensured, the construction speed is increased, various construction and production activities in the grid structure coverage area can not be influenced, and the method has remarkable economic benefits and general popularization value.

Description

technical field [0001] The invention relates to an assembly and installation method of a large-scale roof grid structure used in industry, agriculture, markets and entertainment facilities, and belongs to the technical field of installation methods for high-altitude large-span grid structures. Background technique [0002] With the development of production and the needs of people's lives, many large roof grid structures are widely used in industrial plants, agricultural greenhouses, farmers' markets, botanical gardens, zoos, playgrounds and other places, providing important activities for people's work and life site. At present, the assembly and installation methods of the large-span roof grid structure mainly include the loose assembly method and the tire frame moving method. The loose assembly method is to start assembling a small section of grid on the ground, use a crane to lift and install it, and then install it in pieces in the air, and advance step by step until th...
