Description
Technical field
The utility model is related to a kind of double-deck quadrangular pyramid reticulated shell steel structure cooling towers, and in particular to a kind of pair of local strengthening
Layer quadrangular pyramid reticulated shell steel structure cooling tower, belongs to field of civil engineering.
Background technology
Now currently, gravity-flow ventilation Hyperbolic cooling tower mostly uses greatly traditional reinforced concrete structure, but in recent years, with
The superior structure performance of implementation and steel construction high-strength light energetically of national building industrialization, steel structure cooling tower is increasingly
Favored.But ultra-large type single layer head tower structural elements and nodal moment are big, and the bending stiffness of assembling type node is difficult to meet and want
It asks.Using welding rigid joint, overhead welding constructional difficulties and quality is difficult to ensure.In addition to this, single layer head tower steel using amount it is big,
Rigidity very stability bearing capacity is all relatively low.Therefore, it is directed to current single-layer steel structure cooling tower problems faced, it is proposed that a kind of
The double-deck quadrangular pyramid reticulated shell steel structure cooling tower of local strengthening.
Utility model content
The utility model big, bearing capacity height for the existing ultra-large type single-layer steel structure cooling tower fabricated construction difficulty of solution
Low, the higher problem of cost, and then propose a kind of double-deck quadrangular pyramid reticulated shell steel structure cooling tower of local strengthening.
The utility model adopts the technical scheme that in order to solve the above problem：The utility model includes Double-level Reticulated Shell, lattice
The oblique column of formula, multiple circumferential reinforcement truss and multiple longitudinally reinforced truss, multiple circumferential truss of reinforcing from top to bottom are set gradually,
Multiple longitudinally reinforced truss be along the circumferential direction mounted on it is circumferential reinforce on truss, multiple circumferential truss and multiple longitudinally reinforced reinforced
Truss forms an outer profile, and from top to bottom the cone table of flaring, Double-level Reticulated Shell are sleeved on the cone table successively, lattice
Oblique column is arranged in the bottom of the cone table.
Further, Double-level Reticulated Shell, circumferential reinforcement truss, longitudinally reinforced truss are by multiple quadrangular pyramid structure compositions.
Further, the reticular structure that the oblique column of lattice is made of multiple lattice columns and multiple lattice column web members.
Further, multiple longitudinally reinforced truss refer to six longitudinally reinforced truss, and six longitudinally reinforced truss are with described
Cone table center is that the center of circle is along the circumferential direction uniformly arranged.
The utility model has the beneficial effects that：1, the utility model is compared with single layer, the double-deck quadrangular pyramid reticulated shell rod piece stress point
Cloth is uniform, and strength of materials utilization rate is high；2, for the utility model compared with single layer, assembled bolted spherical node can be used in node, is easy to
Realize that fabricated construction, speed of application are fast；3, the utility model stablizes carrying compared with general clad steel cooling tower, the charming appearance and behaviour of structure
Power and rigidity higher, globality are good.And it is not susceptible to structure partial unstable failure, the bearing capacity of structure can obtain bigger journey
Degree plays.
