Description

Technical Field

[0001] The utility model belongs to the field of large-span grid structure coal storage shed design, and in particular relates to a large-span grid structure coal storage shed gable structure. Background Art

[0002] As the span and height of the coal storage shed increase, the span and height of the gables at both ends are also getting higher and higher. Therefore, based on the design requirements of economy, storage and transportation, cleanliness, environmental protection, and green energy saving, it is very important to choose a reasonable structural form for the gable design. A reasonable gable structure can not only meet the requirements of bearing the gable wind load, but also reduce the temperature stress in the gable span direction and the horizontal thrust transmitted to the grid structure supports at both ends, and ensure the stability of the structural system and better economic indicators. At present, there are mainly the following types of gables for large-span grid structure coal storage sheds:

[0003] (1) Grid gable. The main gable is made into a double-layer flat grid, which is supported on the top of the lower concrete column and the upper chord node of the grid structure coal storage shed. It has a large overall stiffness. In addition to transmitting wind loads, it can also share the end roof vertical load with the grid structure coal storage shed. It is the gable structure with the largest number of rods. Its disadvantages are that there are many rods, the temperature along the span direction is high, resulting in a large cross-section of the rods between the supports, and the horizontal thrust transmitted to the grid structure coal storage shed supports at both ends is particularly large, so it is necessary to set a temperature joint, use a large amount of steel, the grid height is high, the installation is difficult, there are many high-altitude operations, the construction period is long, and the site space is too large.

[0004] (2) Lattice truss gable. Lattice trusses are used as gable wind trusses, and rigid tie rods and support systems are set outside the truss plane. The wind trusses are supported on the top of concrete columns and the upper chord nodes of the grid structure coal storage shed, which reduces the problem of temperature stress. However, since the gable height exceeds 50m, the truss height is relatively high, and the truss cross-section size is too large, which affects the coal stacking and bucket wheel operation near the gable. At the same time, the cross-section of the truss rods is also large, and the amount of steel used is large, which is not economical.

[0005] (3) Steel gable. H-shaped steel or box-shaped sections are used as gable wind-resistant columns, and rigid tie rods and support systems are set outside the plane. Since the height of the gable exceeds 50m, the solid-web wind-resistant columns have large sections and heavy weight, making them difficult to lift and install. In addition, they use a large amount of steel, which is not economical and also results in a large section of the lower concrete column. Utility Model Content
