Description

Technical Field

[0001] The present invention relates to the technical field of thermal power steel structures, and more specifically, to a thermal power steel structure component and a thermal power steel structure that can be quickly spliced. Background Art

[0002] Thermal power plants use coal-fired boilers to heat water to generate steam, which drives the turbine generator to generate electricity. The flue gas generated by the coal burning in the boiler is transported through the flue, and after dust removal, desulfurization and denitrification, it is discharged into the atmosphere from the chimney. Therefore, the flue plays an indispensable role in the operation of thermal power plants.

[0003] In the prior art, the flue is composed of four flue walls, and a plurality of steel frame members are arranged and fixed at equal intervals along the flow direction of the flue on each side of the flue outer wall, and the steel frame members on adjacent outer walls are connected. The arrangement structure of the flue inner support rods is arranged in each flue cross section surrounded by the steel frame members, and the arrangement structure includes three transverse inner support rods arranged in the vertical direction and one vertical inner support rod arranged in the horizontal direction.

[0004] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0005] As the number of large-scale thermal power plants in China increases, the huge amount of flue gas leads to a larger and larger cross-sectional area of ​​the flue, and the horizontal loads such as wind load and earthquake load borne by the transverse inner support rods increase accordingly. With the increase of the cross-sectional area of ​​the flue, the horizontal stiffness and horizontal bearing capacity of the arrangement structure of the inner support rods of the existing flue are weak, which easily causes excessive horizontal deformation of the flue and poses a hidden danger to production safety. In addition, the steel structure of the existing thermal power plant generally adopts steel structure rods, which are spliced ​​on site, which leads to a longer processing time cycle and affects the progress of the project.

[0028] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] See also Figure 1 , and combined with Figure 2 , Figure 3 and Figure 4 As shown, a rapidly assembled firepower steel structure assembly of the present invention includes a main rod 10 , a connecting rod 11 and four frame rods 12 .

[0030] Among them, four frame rods 12 are arranged in parallel in a rectangular shape with the main rod 10 as the center. The main rod 10 is arranged with the frame rod 12 in parallel. The frame rods 12 are connected by connecting rods 11. The connection between the connecting rods 11 and the frame rods 12 can be vertical or inclined. In order to ensure the strength of the overall connection, the connection between the connecting rods 11 and the frame rods 12 of the present invention is a mixed connection, that is, within the same spacing, the connecting rods 11 and the frame rods 12 between the four frame rods 12 are vertical, and the connecting rods 11 and the frame rods 12 between the frame rods 12 are connected in an inclined manner. The vertical structure of the frame rods 12 and the connecting rods 11 ensures the stability of the overall frame, and the connecting rods 11 and the frame rods 12 connected in an inclined manner ensure the balance of force, thereby effectively improving the overall strength.

[0031] Please continue reading Figure 1 As shown, a plurality of support rings 20 are evenly spaced apart on the main rod 10 of the present invention, and connecting rods 21 connected to the frame rods 12 are provided on the support rings 20, and connecting rods 11 are provided between the frame rods 12, that is, the main rod 10 and the frame rods 12 are connected by the connecting rods 21 on the support rings 20. When the frame rods 12 are subjected to force, the force can be transmitted to the main rod 10 through the connecting rods 21, and the connecting rods 11 on the support rings 20 can be used to realize rapid transmission of the force, so as to quickly decompose the force and ensure its strength.

[0032] One end of the frame rod 12 of the present invention is provided with a connector 14, and the connector 14 is provided with a connecting hole 15; the other end of the frame rod 12 is provided with a slot 16, and the slot 16 is adapted to the connector 14 and a connecting screw 17 is installed on the connector 14. That is, in actual use, since the length of the firepower steel structure is relatively large, it needs to be spliced ​​and welded on site. At present, its processing mainly depends on processing various profiles in the factory according to the design, and transporting them to the site for assembly welding. However, this steel structure is located at a relatively high position, so it is difficult to weld on site, and the construction safety hazards of the construction personnel are great. By adopting the technical solution of the present invention, the module processing can be carried out in the factory according to the design to form a firepower steel structure assembly that can be quickly spliced ​​in the present application, and then it can be transported to the site, and the site can be hoisted according to the design, and then the structure of the slot 16 and the connecting hole 15 on the frame rod 12 on the firepower steel structure assembly that can be quickly spliced ​​is combined on site, and the construction period is short, and the installation is convenient and fast.

[0033] It is worth noting that the main rod 10, the frame rod 12 and the connecting rod 11 of the present invention are hollow rods, and the main rod 10, the frame rod 12 and the connecting rod 11 can be straight or curved to meet different needs.

[0034] Preferably, a pull rod 22 is provided on the support ring 20 of the present invention, and the pull rod 22 passes through the support ring 20 and the main rod 10.

[0035] The present invention further comprises a seat body 30 mounted on the member to be connected, and the seat body 30 is connected to the adapter 24 via an inclined tie 31 .

[0036] During the processing, in order to ensure that it can be quickly connected with the on-site wall parts, the present invention is provided with a pull rod 22 on the support ring 20. Through the structural design of the pull rod 22, utilizing the card groove 16 and the locking shaft 26 on the pull rod 22, it can be quickly spliced ​​with the on-site wall parts to achieve its fixation, thereby reducing the difficulty of lifting during the construction process.

[0037] Furthermore, the seat body 30 of the present invention is arranged at intervals in the length direction of the main rod 10, and the seat body 30 is arranged between two adjacent support rings 20, and the connectors 14 on the two adjacent support rings 20 are connected to the same seat body 30 through the inclined pull 31, and the angle between the two inclined pulls 31 on the seat body 30 is greater than 60° and less than 135°. The specific structure is as follows Figure 6 shown.

[0038] The present invention designs the support rings 20 on the main rod 10 with an even number structure, and utilizes the inclined pulls 31 on adjacent support rings 20 to connect with the same seat body 30, thereby achieving self-offsetting of external forces, thereby improving its overall force stability.

[0039] Further, in order to improve its overall stability, the connecting rods 11 near the two ends of the frame rod 12 of the present invention are designed in a rectangular structure, and a splicing plate 32 is mounted on the connecting rod 11.

[0040] When in use, during the splicing process, the splicing plate 32 can be fixed and locked by means of the connection holes 15 and bolts, etc., to further ensure the stability of the overall structural force and the strength of the connection.

[0041] like Figure 4As shown, the present invention also provides a firepower steel structure, including a firepower steel structure assembly that can be quickly spliced ​​as above, and the firepower steel structure assembly is connected by a slot 16 and a connector 14 and is locked by connecting bolts.
