Description

A ground three-dimensional assembly method of space pipe truss

technical field

The invention relates to the field of steel structure construction, in particular to a ground three-dimensional assembling method of a space pipe truss.

Background technique

In recent years, with the development of steel structures, there are more and more large-space steel structure buildings, and the structural form of large-space steel structure buildings mostly adopts space pipe truss steel structures, and the large-span space pipe trusses are larger in size (height and width are more greater than 5m). The construction methods of this type of truss mostly use ground assembly and segmental hoisting, and there are various ground assembly methods, most of which are not systematic, and cannot complete the assembly of pipe trusses efficiently and with quality and quantity.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned defects, and provide a three-dimensional ground assembling method for space pipe trusses that can quickly realize the ground assembly of space pipe trusses while ensuring the safety and reliability of the assembled support system and the quality of truss assembly.

In order to achieve the above object, the present invention is achieved in that:

A three-dimensional ground assembly method for space pipe trusses, including vertical ladders, high-altitude horizontal passages, adjustable corbels, fall arresters, rigid tie rods, oblique supports, horse stools, ground beams, columns, and flexible inter-column supports; The above steps:

Step 1. Assemble the column, ground beam, oblique support, adjustable corbel, vertical ladder, fall arrester, and horse stool into a single piece on the ground;

Step 2. Set up the single piece assembled in step 1 as a whole, and install rigid tie rods and flexible inter-column supports to form a stable structural system;

Step 3, install the high-altitude horizontal channel, and complete the installation of the entire assembled tire rack system;

Step 4. Lift the lower chord of the space pipe truss on the horse stool;

Step 5. Lift the upper chord of the space pipe truss on the adjustable corbel;

Step 6, hoisting the diagonal members of the space pipe truss to complete the welding of the entire space truss;

Step 7, hoisting the space tube truss as a whole.

This three-dimensional assembly method is a bent support system composed of support column system, longitudinal rigid tie rod, flexible support between columns, ground beam, oblique support and adjustable corbel. The components are connected by bolts to facilitate disassembly. It can be installed and adjusted repeatedly, and can be flexibly adjusted according to the type of space truss to achieve the effects of quick assembly, quick adjustment, and repeated turnover.

Detailed ways

The present invention is further illustrated below by specific examples.

As shown in Figures 1 to 4, a three-dimensional assembly method for space pipe trusses on the ground, including vertical ladders 1, high-altitude horizontal passages 2, adjustable corbels 3, fall arresters 4, rigid tie rods 5, oblique supports 6, Horse stool 7, ground beam 8, column 9, support 10 between flexible columns; also include the following steps:

Step 1. Assemble the column 9, the ground beam 8, the oblique support 6, the adjustable corbel 3, the vertical ladder 1, the fall arrester 5, and the horse stool 7 into a monolithic whole on the ground;

Step 2, erecting the single piece assembled in step 1 as a whole, installing rigid tie rods 5 and flexible inter-column supports 10 to form a stable structural system;

Step 3, install the high-altitude horizontal channel 2, and complete the installation of the entire assembled tire frame system;

Step 4, hoisting the lower chord of the space pipe truss on the horse stool 6;

Step 5, hoisting the upper chord of the space pipe truss on the adjustable corbel 3;

Step 6, hoisting the diagonal members of the space pipe truss to complete the welding of the entire space truss;

Step 7, hoisting the space tube truss as a whole.

This three-dimensional assembly method is a bent support system composed of support column system, longitudinal rigid tie rod, flexible support between columns, ground beam, oblique support and adjustable corbel. The components are connected by bolts to facilitate disassembly. It can be installed and adjusted repeatedly, and can be flexibly adjusted according to the type of space truss to achieve the effects of quick assembly, quick adjustment, and repeated turnover.
