Description

A kind of external connection structure and storage tank of storage tank tank deck and tank skin
Technical field
The present invention relates to Process Equipment Technology fields, in particular to the outside between a kind of storage tank tank deck and tank skin Connection structure and a kind of storage tank.
Background technique
In Process Equipment design, as tank diameter increases, tank deck self weight is continued to increase, and tradition is reinforced ring structure and is difficult to Operative constraint is provided for tank deck, it can not operative constraint tank deck periphery circumferential direction and radial moment of flexure.
Summary of the invention
The present invention is directed to solve at least one of the technical problems existing in the prior art or related technologies.
In view of this, it is an object of the present invention to provide the external connection knots between a kind of storage tank tank deck and tank skin Structure.
It is another object of the present invention to provide a kind of external connection knots between above-mentioned storage tank tank deck and tank skin The storage tank of structure.
To achieve the goals above, the technical solution of first aspect present invention provides between a kind of storage tank tank deck and tank skin External connection structure, tank deck be set to tank skin on the upside of, comprising: multiple mounting brackets, mounting bracket are successively set along the circumferential direction of tank deck It sets;Multiple fixed brackets, fixed bracket are fixedly arranged on the outside of tank skin and are correspondingly arranged with mounting bracket, fix bracket and tell peace It is detachably connected to fill bracket.
The external connection structure between storage tank tank deck and tank skin that this programme provides, being capable of operative constraint tank deck periphery circumferential direction With radial moment of flexure, tank deck and tank skin tie point are improved in carrying compared with the Local security under big load, while being provided reliable Design considerations.It effectively prevents in standard calculation and check, is checked because lacking Local security, generate security risk.Energy simultaneously It is enough preferably to cope with corrosive conditions.
Specifically, fixed bracket and mounting bracket are detachably connected, by fixing the cooperation of bracket and mounting bracket, Form rigid joint.The axial force and moment of flexure of tank deck can transmit downwards completely and by tank deck, fixed bracket, mounting bracket and Tank skin shared, so as to increase the local bearing capacity of tank skin and tank deck coupling part, operative constraint tank deck peripheral ring To with radial moment of flexure.
Under special big load operating condition, this programme offer structural bearing capacity is more preferable, significantly increases tank deck and tank skin Load-carrying properties at tie point have contained that local stability is low, have been also easy to produce the problem of crippling, while significantly having been promoted To the non-deformability of sporadic load, the risk hidden danger in design can be decreased or even eliminated.
It is worth noting that abandoned the mode that traditional tank deck and tank skin are welded to connect in this programme, can be avoided because Welding defect leads to tank deck and the below standard possibility of tank skin bonding strength.Mounting bracket and fixed branch are set up in tank deck and tank skin Outside, both it is convenient for the installation of tank deck and tank skin, while can be avoided under corrosive conditions because corrosion causes tank deck to connect by force with tank skin The case where degree reduces.
It is also pointed out that multiple mounting brackets are correspondingly arranged with multiple fixed brackets in this programme, it is both strong convenient for guaranteeing Degree, additionally it is possible to save material, reduce self weight and the production cost of the external connection structure between storage tank tank deck and tank skin, be convenient for Large-scale application.
