Problems solved by technology

For example, some nodes are inconvenient to install on site, resulting in higher installation costs; some nodes that are more convenient to install, such as plate nodes, will have certain protrusions at the nodes after installation, which will affect the tightness of the formed steel reticulated shell structure and skin and some nodes cannot be used in the large-span reticulated shell structure of the oil storage tank due to restrictions such as self-weight; in addition, the strength of some nodes cannot meet the standard

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention will be further described.

[0020] Such as figure 1 -As shown in 4 and 6, a joint between the top rods of the reticulated shell of the vault storage tank includes a lower plate body 1, an upper plate body 2, six bolts 3, six nuts 4, and six grooved formed steel 5; The disc body 1 and the upper disc body 2 are regular hexagonal annular structures symmetrical up and down, with threaded through holes 6 at the top corners of the hexagon, and a slit 7 at the midpoint of each side of the hexagonal structure. ;

[0021] Such as Figure 5 As shown, the grooved formed steel 5 is made up of a rib plate 51, two wing plates 52 of the same shape and size and two fixing blocks 53 of the same shape and size, and the two fixing blocks 53 are installed on the upper and lower sides of the left end of the rib plate 51 respectively. On both sides, two wing plates 52 are installed on the upper and lower sides of the r...

Abstract

The invention discloses a node between vault petroleum storage tank reticulated shell ejector pins. The node comprises plate components, bolts, nuts, springs and gaskets. The node has the advantages that the node is convenient to mount, small in overall stress in actual application, simple in structure, novel in concept, safe and reliable, and applicable to vault reticulated shell storage tanks above 20000m<3> in volume, and various pieces of forming steel are connected through the node by using fastening principles to form a reticulated shell.

Description

technical field [0001] The invention relates to a node between ejector rods of a reticulated shell of a vault storage tank, belonging to the field of petrochemical storage and transportation equipment. Background technique [0002] The reticulated shell structure is widely used in civil engineering, mostly in large venues such as gymnasiums, and its structure and technology are relatively mature. With the development of large-scale refined oil storage tanks, it has become an inevitable trend to adopt space reticulated shell structure as the tank roof. Although the reticulated shell structure has a mature theory and design basis in the construction industry, there are still many technical problems in how to apply it to large storage tanks. For example, some nodes are inconvenient to install on site, resulting in higher installation costs; some nodes that are more convenient to install, such as plate nodes, will have certain protrusions at the nodes after installation, which ...
