[0048] The present invention will be further explained below in conjunction with the drawings:

[0049] Combine figure 1 , figure 2 As shown, the spherical tank system with the combined support of the reticulated shell-ring truss-shaped combined column can be moved slightly, including the combined spherical tank 1, the combined support of the reticulated shell-ring truss-shaped combined column, and the rubber ball-damper for shock absorption and energy consumption. Device; combined support of reticulated shell-ring truss-shaped composite column, ring truss 3 surrounds the outside of reticulated shell 2, ring truss 3 is connected with special-shaped composite column 4; combined spherical tank 1 is set in the combination of reticulated shell-ring truss-shaped composite column On the support, a rubber ball-damper shock absorption and energy dissipation device is arranged between the reticulated shell node 18 and the combined spherical tank 1. The ring truss 3 is arranged between the reticulated shell 2 and the special-shaped composite column 4, the load of the spherical tank and the reticulated shell 2 is transmitted to the special-shaped composite column 4 through the ring truss 3, and the special-shaped composite column 4 transfers the load to the foundation.

[0050] In the present invention, the combined spherical tank 1 is formed by connecting a single layer of spherical arc-shaped GFRP plates 14. A connecting slot is arranged between the spherical arc-shaped GFRP plates 14, and a reliable connection is realized by bolts after butting.

[0051] In the present invention, the combined spherical tank 1 can also be formed by connecting the inner and outer layers of spherical arc-shaped GFRP plates 14. Connecting keys are arranged between the double-layer spherical arc-shaped GFRP plates 14, so that the two layers of GFRP plates 14 can bear the force together and improve The stiffness and strength of the spherical tank.

[0052] The combined spherical tank 1 of the present invention can also be formed by connecting double-layer spherical GFRP plates 14 filled with lightweight aggregate concrete or reactive powder concrete to form a combined spherical tank wall. When the diameter of the spherical tank needs to be larger, the Fill light aggregate concrete or reactive powder concrete between two layers of GFRP board 14 to improve the stability of the spherical tank, such as Figure 7 The combined spherical tank shown is formed by connecting two-layer spherical arc-shaped GFRP plates.

[0053] Combine Figure 4 , Figure 5 , Image 6 , Figure 7 The rubber ball-damper shock absorption and energy dissipation device is composed of a damper 6 and a rubber ball 5. The rubber ball 5 is arranged at one end of the damper 6. The outer wall of the combined spherical tank 1 has an inner concave slide 7, and the rubber ball 5 is located in the inner concave slide. In the road 7, the other end of the damper 6 is fixed to the reticulated shell node 18; the rubber ball-damper damping energy dissipation device can shrink back and forth under the action of force to achieve the purpose of energy dissipation and shock absorption, not only can load the spherical tank It is transmitted to the reticulated shell structure, and can ensure that the tank body can move slightly in any direction, thereby transmitting the energy of the spherical tank itself and ensuring that the spherical tank is intact.

[0054] Refer to image 3 As shown, the special-shaped composite column 4 is composed of solid web section steel 8 and reinforced concrete 9. The solid web section steel 8 is placed in the reinforced concrete 9. The top of the combined column has an L-shaped support base, which can be used for two-way plate rubber Energy-consuming supports provide support. The special-shaped composite column 4 not only has high bearing capacity, but also has good seismic performance. To select a special-shaped column and to meet the needs of functions, horizontal and vertical support anchors can be welded to the built-in steel at the top of the column or at the variable section.

[0055] Such as Figure 8 As shown, the annular truss 3 and the special-shaped composite column 4 are connected by a two-way plate type rubber energy dissipation support, which is fixed together by a node support 10, a rubber plate 11 and a backing plate 16 through an anchor 17 Formed, there are two pairs of node support 10, rubber plate 11 and backing plate 16, one pair is arranged horizontally, and the other pair is arranged vertically. The two-way plate type rubber energy dissipation support passes through the anchor bolt 17 and the L of the combined column. Type support bases are connected; two-way plate-type rubber energy dissipating bases are welded to the nodes of the ring truss through node supports. Reliable connection can be achieved through the two-way plate rubber energy-consuming support, which can play the role of energy dissipation and shock absorption, and greatly reduce the seismic force of the reticulated shell under the action of earthquake.

[0056] In the present invention, the reticulated shell 2 can be divided into a single-layer concave-shaped reticulated shell supporting system with apex Picture 9 Shown) and single-layer concave non-apex reticulated shell support system (such as figure 1 As shown), considering the convenience of oil inlet and outlet at the upper and lower ends of the spherical tank, a single-layer recessed no-apex reticulated shell support system can be used. For storage tanks where the storage medium enters and exits the tank body for a long period of time, a single-layer recessed grid shell support system with apex can be used, and holes are opened at the grid shell spaces at both ends of the storage tank as entrances and exits. In areas of high seismic intensity, a single-layer, apex integral reticulated shell support system (such as Picture 11 Shown) and single-layer non-vertex integral reticulated shell support system (such as Picture 10 Shown). A rubber ball-damper shock absorption and energy dissipation device is arranged between all the reticulated shell nodes and the spherical tank, which can not only make the spherical tank have a small displacement, but also effectively limit the vertical vibration of the spherical tank.

[0057] For spherical tanks with special requirements for the storage medium, a reticulated dome 12 can be set on the top of the spherical tank, so as to avoid rain, snow, impurities, etc. on the top of the tank. A single-layer concave prestressed reticulated shell support system (such as Figure 13 Shown) and single-layer concave prestressed reticulated shell multi-point support system (such as Figure 14 As shown), the single-layer concave prestressed reticulated shell multi-point support system is also supported by vertical trusses, such as Figure 18 As shown, one side of the vertical truss is fixed to the special-shaped composite column 4, and the other side is connected to the reticulated shell node 18. One end of a steel strand suspension rod is fixed on the spherical tank supporting ring truss, and the other end is connected to the top of the special-shaped composite column, or a tie rod system is set on the column to connect to the mesh shell node to transmit the load to the composite column. This kind of pre-stressed reticulated shell support system can not only make full use of high-strength materials to realize multi-path load transfer, but also can uninterrupted medium access in bad weather.

[0058] There are multiple joint supports of reticulated shell-ring truss-shaped composite column, and two adjacent reticulated shells-ring truss-shaped composite column joint supports share a special-shaped composite column 4, see Figure 16 The cross-section of the shared special-shaped combined column 4 is cross-shaped, and the connecting beams 15 are arranged between the special-shaped combined columns 4; each net shell 2 is provided with a combined spherical tank 1.

[0059] Figure 15 It is a schematic diagram of the joint support of two reticulated shells and special-shaped composite columns. This is a single-layer reticulated shell-special-shaped composite column joint support system. Two reticulated shells and special-shaped composite columns are jointly supported on the same layer.

[0060] Figure 19 A schematic diagram of the combined support of four reticulated shells and special-shaped combined columns is provided. This is a single-layer reticulated shell-shaped combined column combined support system. The four reticulated shells and special-shaped combined columns are jointly supported on the same layer. Figure 17 It is a schematic diagram of the four reticulated shells-special-shaped combined columns supporting the middle reticulated shell.

[0061] Picture 20 It is a schematic diagram of the combined support of multi-layer reticulated shells and special-shaped composite columns. This is a two-layer reticulated shell-shaped composite column combined support system. The two reticulated shells in the lower layer are jointly supported by special-shaped composite columns, and the upper layer also has two reticulated shells-shaped Combined column joint support.

[0062] The construction method of the single-layer concave reticulated shell-ring truss-special-shaped combined column combined support system in the present invention:

[0063] First, complete the reinforced concrete foundation under the built-in solid-web steel special-shaped composite column 4, fix the built-in steel in the foundation, and then tie the steel bars on the periphery, support the formwork, and pour the concrete. Because the special-shaped column is taller, it is generally required to be poured in sections. When pouring to the top, the anchors 17 of the 8 horizontal and vertical two-way plate rubber energy dissipation bearings are welded with the built-in section steel and embedded in the concrete. After the compressive strength reaches the design value, install the two-way plate-type rubber energy-consuming support, and fix the two-way plate-type rubber energy-consuming support on the combined column by tightening the nuts of 8 groups of anchor bolts.

[0064] Transport the prefabricated round steel pipe rods and nodes to the site, and assemble them on the ground into an upper convex reticulated shell 2, with or without vertices, and then weld the ring-shaped lower steel truss with the reticulated shell nodes. The structural system at this time The placement is just the opposite of the use. The purpose of this is to facilitate construction, and the system can be placed on the ground smoothly with good stability. After welding, the prefabricated rubber ball-damper energy dissipation device is installed on the inner node of the reticulated shell, and the direction points to the center of the sphere. After debugging the rubber ball-damper damping energy dissipation device and the node connection are all normal, use the crane to turn the reticulated shell 2 upside down, hoist it in translation and place it on the two-way plate rubber energy dissipation support, adjust the nodes and nodes of the ring truss The support 10 is well welded.

[0065] Assemble the GFRP combination spherical tank 1, connect the single-layer spherical arc-shaped GFRP plate 14 to the connecting slot and achieve reliable connection through special bolts. The nut is glued to the corresponding inner bolt opening, and the end of the screw is flush with the inner nut after tightening , Connect the single-layer spherical arc-shaped GFRP board 14 standard parts in sequence and accurately.

[0066] If a spherical tank composed of double-layer spherical GFRP plates 14 is used, the double-layer standard parts are connected to the slot and the special bolts are used to achieve reliable connection. The inner nut is glued to the corresponding bolt opening, and the special bolt is screwed from the outside to the inside. In order to enter, the length of the screw is required to be very high, and the reliable connection of the two-layer GFRP board 14 must be realized, and the end surface of the screw is flush with the inner nut after tightening. Connect the standard parts of the double-layer spherical arc-shaped GFRP board 14 in sequence and accurately.

[0067] When the diameter of the spherical tank needs to be larger, lightweight aggregate concrete or reactive powder concrete can be filled between the two layers of GFRP panels 14 to form a combined spherical tank wall, which greatly increases the bearing capacity and rigidity of the spherical tank.

[0068] After the spherical tank is assembled, it is hoisted to the reticulated shell-ring truss-combined column support system to complete the main structure construction.

[0069] The construction method of the single-layer integral reticulated shell-ring truss-special-shaped combined column combined support system in the present invention:

[0070] First, complete the reinforced concrete foundation under the built-in solid web shaped steel special-shaped composite column, fix the built-in steel in the foundation, and then bind the steel bar, support form, and pour the concrete on the periphery. Because the special-shaped column is taller, it generally needs to be poured in sections , When pouring to the top, weld the anchors 17 of the 8 horizontal and vertical two-way plate rubber energy dissipation bearings with the built-in section steel and embed them in the concrete. When the concrete compressive strength reaches the design value, install the two-way plate For the rubber energy-consuming support, the two-way plate rubber energy-consuming support is fixed on the combined column by tightening the nuts of 8 groups of anchor bolts.

[0071] Transport the round steel pipe rods and nodes prefabricated in the factory to the site, and assemble the designed A group and B group on the ground, a total of two sets of convex reticulated shells, with or without vertices, of which group A will be used as a concave The net shell is placed under the spherical tank, and group B is still used as an upward convex net shell and placed on the spherical tank. Weld the ring-shaped lower steel truss with the reticulated shell of Group A. At this time, the reticulated shell system is placed just opposite to the use. The purpose of this is to facilitate the construction, and the system can be placed on the ground smoothly with good stability. After welding, install the prefabricated rubber ball-damper energy dissipation device on the inner nodes of the A and B reticulated shells, with the direction pointing to the center of the sphere. After debugging the rubber ball-damper energy dissipation device and the connection of the nodes are all normal, use a crane to turn the group A reticulated shell upside down, hoist it and place it on the bidirectional plate rubber energy dissipation support of the special-shaped column, adjust the ring truss The joint and the joint support are well welded.

[0072] Assemble the GFRP combination spherical tank 1, connect the single-layer spherical arc-shaped GFRP plate 14 to the connecting slot and achieve reliable connection through special bolts. The nut is glued to the corresponding inner bolt opening, and the end of the screw is flush with the inner nut after tightening , Connect the single-layer spherical arc-shaped GFRP board 14 standard parts in sequence and accurately.

[0073] If a spherical tank composed of double-layer spherical GFRP plates 14 is used, the double-layer standard parts are connected to the slot and the special bolts are used to achieve reliable connection. The inner nut is glued to the corresponding bolt opening, and the special bolt is screwed from the outside to the inside. In order to enter, the length of the screw is required to be very high, and the reliable connection of the two-layer GFRP board 14 must be realized, and the end surface of the screw is flush with the inner nut after tightening. Connect the standard parts of the double-layer spherical arc-shaped GFRP board 14 in sequence and accurately.

[0074] When the diameter of the spherical tank needs to be larger, lightweight aggregate concrete or reactive powder concrete can be filled between the two layers of GFRP panels 14 to form a combined spherical tank wall, which greatly increases the bearing capacity and rigidity of the spherical tank.

[0075] The quality of the reticulated shell-ring truss-combined special-shaped column combined support spherical tank system is concentrated on the spherical tank. Multi-directional vibration is prone to occur in the high seismic intensity area, the spherical tank will roll, and the normal operation of the spherical tank will be affected. No rolling occurs, only movement occurs. An inner concave slide is set on the outer wall of the combined spherical tank and the position corresponding to the energy-consuming damping device. When installing, the slide 7 on the spherical tank corresponds to the rubber ball 5 of the device, which effectively restricts The rolling of the spherical tank.

[0076] After the spherical tank is assembled, it is hoisted into position in the group A reticulated shell. Then the assembled group B reticulated shell is hoisted and placed on the A group, and the rods of the B group reticulated shell and the nodes of the A group are welded together to form an integral reticulated shell system to wrap the spherical tank. Although the group B reticulated shell does not bear the load of the GFRP spherical tank, the installation of the rubber ball-damper energy dissipation device has a better restraint on the vertical vibration of the spherical tank caused by the earthquake, which greatly limits the spherical tank. The vertical displacement effectively prevents the spherical tank from colliding with the net shell. Then, reliable welding is realized between the upper ring steel truss, the lower ring steel truss and the reticulated shell nodes. In addition to providing support, the ring truss 3 can also be used as a platform for inspection and maintenance of the system to complete the construction of the main structure.

[0077] The construction method of the single-layer concave prestressed reticulated shell-ring truss-special-shaped combined column combined support system in the present invention:

[0078] First, complete the reinforced concrete foundation under the built-in solid-web steel special-shaped composite column, fix the built-in steel in the foundation, and then tie the steel bars on the periphery, support the formwork, and pour the concrete. Because the dome reticulated shell is used as the roof, the special-shaped column needs to be made into a variable-section column, and a support for the spherical tank system is set at the variable section. The following section uses 1-1 section, and the column top supports the dome roof with a 3-3 section. Because the special-shaped column is taller, it is generally required to be poured in sections. When pouring to the variable cross-section, the anchor bolts of the 8 horizontal and vertical two-way plate type rubber energy dissipation bearings and the built-in steel are welded and pre-embedded in the concrete. When pouring to the top of the column, the pre-stressed embedded parts are embedded in the concrete. When the compressive strength of the concrete reaches the design value, install the two-way plate rubber energy-dissipating support, and tighten the nuts of 8 groups of anchor bolts. The support is fixed on the combined column.

[0079] Transport the prefabricated round steel pipe rods and nodes to the site, and assemble them on the ground into an upper convex reticulated shell, with or without vertices, and then weld the ring-shaped lower steel truss with the reticulated shell nodes. At this time, the structural system is placed It's just the opposite of using it. The purpose of this is to facilitate construction, and the system can be placed on the ground stably with good stability. After welding, install the prefabricated rubber ball-damper energy dissipation and shock absorption device on the inner node of the reticulated shell 2, with the direction pointing to the center of the sphere. After debugging the damping device and the connection of the nodes are all normal, use a crane to turn the reticulated shell 2 upside down, hoist it in translation and place it on the two-way plate-type rubber energy-consuming support. After adjustment, the nodes of the ring truss and the node supports 10 are welded intact.

[0080] Assemble the GFRP combined spherical tank, connect the single-layer arc-shaped GFRP plate 14 with the connecting slot and realize reliable connection through special bolts, glue the nut to the corresponding inner bolt opening, and tighten the screw end face to be flush with the inner nut. Connect the standard parts of the single-layer spherical GFRP board 14 accurately in sequence.

[0081] If a spherical tank composed of double-layer spherical GFRP plates 14 is used, the double-layer standard parts are connected to the slot and the special bolts are used to achieve reliable connection. The inner nut is glued to the corresponding bolt opening, and the special bolt is screwed from the outside to the inside. In order to enter, the length of the screw is required to be very high, and the reliable connection of the two-layer GFRP board 14 must be realized, and the end surface of the screw is flush with the inner nut after tightening. Connect the standard parts of the double-layer spherical arc-shaped GFRP board 14 in sequence and accurately.

[0082] When the diameter of the spherical tank needs to be larger, lightweight aggregate concrete or reactive powder concrete can be filled between the two layers of GFRP panels 14 to form a combined spherical tank wall, which greatly increases the bearing capacity and rigidity of the spherical tank.

[0083] After the spherical tank is assembled, it is hoisted to the reticulated shell-ring truss-combined column support system to accurately place it. Then install the reticulated shell dome 12 and assemble the reticulated shell 2 on the ground. It is hoisted and placed on the top of the column, and it is fixedly connected with the support to achieve a reliable connection. Since this part of the construction is a normal practice, it will not be elaborated.

[0084] Then, one end of the high-strength steel wire boom is fixed on the shared node of the spherical tank supporting ring truss 3 and the reticulated shell 2, and the other end is connected with the embedded part of the special-shaped composite column top, and the 4 groups of prestressed steel wires are stretched and anchored.

[0085] In order to transmit the load of the spherical tank to the reticulated shell to the composite column through multiple channels, in addition to the tensioned prestressed steel wire, the embedded parts are set at the designed position on the column to form a wall-mounted vertical truss. Tie rods are set between the reticulated shells to disperse the load to the composite column, and then complete the construction of the main structure. This kind of pre-stressed reticulated shell support system can not only make full use of high-strength materials to realize multi-path load transfer, but also can uninterrupted medium access in bad weather.

[0086] The construction method of the two-layer group tank system supported by the reticulated shell-ring truss-special-shaped combined column in the present invention:

[0087] First, complete the reinforced concrete foundation under the built-in solid-web steel special-shaped composite column, fix the built-in steel in the foundation, and then tie the steel bars, support the formwork, and pour the concrete on the periphery. Since the combined column needs to support two layers of spherical tanks, the special-shaped column needs to be changed in section twice, and the support of the spherical tank system is set at the variable cross section respectively. Because the special-shaped column is taller, it is generally required to be poured in layers. The frame beam is poured at the designed position and connected with the flange of the composite column. When pouring to the variable cross-section, 8 horizontal and vertical two-way plate rubber The anchor 17 of the energy dissipating support is welded with the built-in section steel and embedded in the concrete. When the compressive strength of the concrete reaches the design value, install the two-way slab rubber energy consuming support. The two-way slab is fixed by tightening the nuts of 8 sets of anchor bolts. The rubber energy dissipating support is fixed on the combined column. Then continue pouring the composite column to complete the pouring of the second-story frame beam. When pouring to the second-story variable section, the anchor bolts of the 8 horizontal and vertical two-way plate rubber energy dissipation bearings and the built-in section steel are welded and pre-embedded in In the concrete, when the compressive strength of the concrete reaches the design value, install the two-way plate rubber energy dissipation support, and fix the two-way plate rubber energy dissipation support on the combined column by tightening the nuts of 8 groups of anchor bolts 17 to complete all the supports in sequence. Installation of the seat.

[0088] The round steel pipe rods and nodes prefabricated in the factory are transported to the site. Since the spans of the two-layer reticulated shell support system are different, the two-span reticulated shell structure must be assembled. First assemble a layer of supporting reticulated shell, and assemble it on the ground into an upper convex no-vertex reticulated shell, and then weld the ring-shaped lower steel truss to the reticulated shell nodes respectively. At this time, the structural system is placed just opposite to the one in use. The purpose of this is The construction is convenient, and the system can be stably placed on the ground with good stability. After welding, the prefabricated rubber ball-damper energy dissipation device is installed on the inner node of the reticulated shell, and the direction points to the center of the sphere. After debugging the damping device and the node connections are all normal, use a crane to turn the reticulated shell upside down, hoist it in translation and place it on a layer of special-shaped column bidirectional plate rubber energy dissipation support. After adjustment, the nodes of the ring truss and the node supports are well welded .

[0089] Assemble the GFRP combined spherical tank, connect the single-layer arc-shaped GFRP plate 14 with the connecting slot and realize reliable connection through special bolts, glue the nut to the corresponding inner bolt opening, and tighten the screw end face to be flush with the inner nut. Connect the standard parts of the single-layer spherical GFRP board 14 accurately in sequence.

[0090] If a spherical tank composed of double-layer spherical GFRP plates 14 is used, the double-layer standard parts are connected to the slot and the special bolts are used to achieve reliable connection. The inner nut is glued to the corresponding bolt opening, and the special bolt is screwed from the outside to the inside. In order to enter, the length of the screw is required to be very high, and the reliable connection of the two-layer GFRP board 14 must be realized, and the end surface of the screw is flush with the inner nut after tightening. Connect the standard parts of the double-layer spherical arc-shaped GFRP board 14 in sequence and accurately.

[0091] When the diameter of the spherical tank needs to be larger, lightweight aggregate concrete or reactive powder concrete can be filled between the two layers of GFRP panels 14 to form a combined spherical tank wall, which greatly increases the bearing capacity and rigidity of the spherical tank.

[0092] After the spherical tank is assembled, it is hoisted to a layer of reticulated shell-ring truss-combined column support system to complete the construction of the main structure of the first layer.

[0093] Assemble the two-layer supporting reticulated shell, and assemble the upper convex non-vertex reticulated shell on the ground, and then weld the ring-shaped lower steel truss to the reticulated shell nodes respectively. At this time, the structural system is placed just opposite to the one used.

After debugging the damping device and the node connections are all normal, use a crane to turn the reticulated shell upside down, hoist it in translation and place it on the two-story special-shaped column two-way plate rubber energy dissipation support. After adjustment, the ring truss node and the node support 10 are welded intact .

[0094] Assemble the two-layer GFRP combined spherical tank in the same way. The diameter of the two-layer spherical tank is larger than that of the first-layer spherical tank.

[0095] After the second-story spherical tank is assembled, it is hoisted to the second-story reticulated shell-ring truss-combined column support system to complete the construction of the second-story main structure. A connecting belt is set between the lower mouth of the second-layer spherical tank and the upper mouth of the first-layer spherical tank, and the liquid medium can be directly injected through the second-layer inlet to achieve the purpose of centralized oil transportation.
