Description
Technical field
The present invention relates to a kind of double-deck quadrangular pyramid reticulated shell steel structure cooling tower, and in particular to a kind of bilayer four of local strengthening
Pyramid reticulated shell steel structure cooling tower, belongs to field of civil engineering.
Background technology
At present now, gravity-flow ventilation Hyperbolic cooling tower uses traditional reinforced concrete structure mostly, 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 individual layer head tower structural elements and nodal moment are big, the bending rigidity of assembling type node is difficult to meet to want
Ask.Using welding rigid joint, overhead welding constructional difficulties and quality is difficult to ensure.In addition, individual 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.
The content of the invention
The present invention for solve existing ultra-large type single-layer steel structure cooling tower fabricated construction difficulty is big, bearing capacity is highly low,
The problem of cost is higher, and then propose a kind of double-deck quadrangular pyramid reticulated shell steel structure cooling tower of local strengthening.
The present invention adopts the technical scheme that to solve the above problems：The present invention include Double-level Reticulated Shell, the oblique column of lattice,
Multiple rings strengthen truss and multiple longitudinally reinforced truss, and multiple rings are strengthened truss and from top to bottom set gradually, multiple longitudinal directions
Strengthen truss to be along the circumferential direction arranged on ring reinforcement truss, multiple rings strengthen truss and multiple longitudinally reinforced truss compositions
From top to bottom the cone table of flaring, Double-level Reticulated Shell are sleeved on the cone table one outline successively, and the oblique column of lattice is set
Put in the bottom of the cone table.
Further, Double-level Reticulated Shell, ring strengthen truss, longitudinally reinforced truss is by multiple quadrangular pyramid structure compositions.
Further, the network structure that the oblique column of lattice is made up 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 beneficial effects of the invention are as follows：1st, the present invention is than individual layer, and double-deck quadrangular pyramid reticulated shell rod member distribution of force is uniform, material
Expect that rate of utilization of strength is high；2nd, the present invention can use assembled bolted spherical node than individual layer, node, it is easy to accomplish assembled is applied
Work, speed of application are fast；3rd, for the present invention than general clad steel cooling tower, the charming appearance and behaviour stability bearing capacity and rigidity of structure are higher, whole
Body is good.And structure partial unstable failure is not susceptible to, the bearing capacity of structure can be played more.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the structural representation for the cone table that ring strengthens truss and longitudinally reinforced truss composition；
Fig. 3 is the structural representation of the oblique column of lattice.
