Abstract
Description
Technical Field
[0001] The utility model relates to the field of power station building overpasses, in particular to a special-shaped curved surface communication overpass for power station buildings. Background Art
[0002] The statements in this section merely mention the background technology related to the present invention and do not necessarily constitute the prior art.
[0003] The connecting overpass is an important part of the public building transportation system of a thermal power plant. As a representative horizontal structure in the power plant, it connects the public buildings closely together like a bond and is an important part of improving the convenience of the power plant.
[0004] As an important node building in the power station, the connecting bridge is greatly restricted by its structural type. For example, the upper and lower structures are separated, and the upper structure of the building is set on the upper part of the lower structure. The components of each part are designed separately through connection points, and the overall stability of the structure is poor. Another example is the use of traditional steel frames or bulky multi-layer steel truss structure systems, such as H-shaped steel columns or box-shaped steel columns + horizontal H-shaped steel beam structures or concrete vertical piers. However, since the construction of the beam-column connection nodes is relatively difficult, the node method occupies a relatively large space, and the amount of steel used is large, the cost is high, and the process pipelines can usually only be arranged at the bottom of the beam inside the bridge and leak out, which occupies a relatively large space. Utility Model Content
[0005] In order to address the deficiencies of the prior art, the first aspect of the present invention provides a special-shaped curved connecting bridge for a power station building, the purpose of which is to improve the overall stability of the bridge by proposing a new spatial structure, while saving the space occupied by the bridge and material costs.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] As an embodiment, a hollow structure is formed between the horizontal floor and the bottom end of the lower curved structure, for accommodating cable trays and control cables.
[0011] As an embodiment, a storage module is provided in the hollow structure between the horizontal floor and the lower end of the lower curved structure.
[0012] As an embodiment, the horizontal floor slab adopts a modular assembled composite slab or a concrete composite floor slab with a corrugated steel plate bottom formwork.
[0013] As an embodiment, the horizontal transverse beam is an arc square steel beam, and the longitudinal circular beam is a circular steel pipe.
[0014] As an implementation method, a maintenance curtain wall is provided on the surface of the upper curved surface structure and the lower curved surface structure. The maintenance curtain wall adopts an integral unit curtain wall and is wrapped around the outside of the overpass body.

[0028] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.
[0029] It should be noted that the present invention is a construction scheme. As for the various device units involved therein, the specific structures for realizing the functions they should realize already exist in the prior art, and the protocols, software or programs involved in the work processing between them also already exist in the prior art. Those skilled in the art are fully aware that the present invention does not make any improvements to the units of each device, and therefore does not involve the content of the software, but relies on the organic integration of various components into a whole, that is, providing a construction scheme.
[0030] As mentioned in the background technology of this application, the connecting bridge is an important node building in the power station and is greatly limited by its structural type. For example, the upper and lower structures are separated, and the upper structure of the floor slab is arranged on the upper part of the lower floor structure, which is realized through connection points and the combined components of each part are designed separately, and the overall stability of the structure is poor. Another example is the use of traditional steel frames or bulky multi-layer steel truss structure systems, such as H-shaped steel columns or box-shaped steel columns + horizontal H-shaped steel beam structures or concrete vertical piers. However, since the construction of the beam-column connection nodes is relatively difficult, the node method occupies a relatively large space, and the amount of steel used is large, the cost is high, and the process pipelines can usually only be arranged at the bottom of the beam inside the overpass and leak out, which occupies a relatively large space.
[0031] The utility model provides an overpass with a stable structure and reasonable space; at the same time, it changes the current situation of disordered process pipelines in traditional overpasses, fully utilizes the top and bottom space of the new overpass, unifies the planning and integration of various process pipelines, and sets up a comprehensive pipeline corridor in the bottom and upper ceiling space of the overpass, thereby improving the space utilization rate of the overpass.
[0032] like Figure 1-Figure 4 The figure shows the overall structure of a new type of special-shaped power station building connecting bridge. The bridge adopts a three-dimensional spatial tube truss system, including the bridge body and supporting structure. The bridge body includes an integrated upper curved surface structure 1 and a lower curved surface structure 2. Multiple horizontal transverse beams 3 and longitudinal circular beams 4 are set on the sides of the upper curved surface structure 1 and the lower curved surface structure 2. The multiple horizontal transverse beams 3 and longitudinal circular beams 4 are fixedly connected.
[0033] The lower curved structure 2 is provided with a horizontal floor 8, and the supporting structure includes a horizontal supporting member 5 and a longitudinal supporting member 6; the horizontal supporting member 5 is provided at the bottom of the horizontal floor 8 and extends and is fixed to the building structure, and the longitudinal supporting member 6 is provided on the bottom surface of the overpass body.
[0034] Through the above solution, the traditional separate upper and lower structural structures are solved and an integrated three-dimensional spatial tube truss system is adopted to ensure the overall stability of the structure.
[0035] In this embodiment, the upper curved surface structure 1 and the lower curved surface structure 2 are symmetrically arranged, with a hollow structure in the middle. After being assembled, the appearance is cylindrical. The bottom surface of the cylinder serves as the two end surfaces of the overpass body and is perpendicular to the horizontal ground. Horizontal transverse beams 3 and longitudinal circular beams 4 are set on the side surfaces of the cylinder.
[0036] In this embodiment, the horizontal transverse beam 3 is an arc-shaped square steel beam, and the structure uses an arc-shaped square steel tube instead of the conventional transverse H-shaped steel beam and column; the longitudinal circular beam 4 uses a circular steel tube to connect the arc-shaped square steel together to form an integral corridor of a three-dimensional tube truss.
[0037] In this embodiment, the horizontal transverse beams 3 and the longitudinal circular beams 4 can be arranged according to the set number and angle, such as Figure 4 The figure shows one of the arrangements; other numbers and angles can also be used.
[0038] In this embodiment, the horizontal support member 5 is welded to the bottom of the horizontal floor slab 8;
[0039] The longitudinal support member 6 is welded to the bottom of the overpass body;
[0040] In this embodiment, the upper curved surface structure 1 is provided with a suspended ceiling 7. A hollow structure is formed between the suspended ceiling 7 and the top of the upper curved surface structure 1 to accommodate fire protection pipes and HVAC passages 9.
[0041] The lower curved structure 2 is provided with a horizontal floor 8, and a hollow structure is formed between the bottom of the horizontal floor 8 and the lower curved structure 2 for accommodating cable trays and control cables 10, etc.;
[0042] Since the connecting overpass is generally of great height, the horizontal floor 8 adopts a prefabricated composite slab or a concrete composite slab with a corrugated steel plate bottom formwork, which has obvious advantages over traditional steel plates or cast-in-place concrete slabs.
[0043] like Figure 5 As shown, in order to ensure the floor rigidity, cross tubular horizontal diagonal braces are added between the steel beam components at the bottom of the horizontal floor 8. According to the height and span of the overpass, the horizontal corridor is supported by vertical components such as steel columns and steel tube trusses to form a connecting overpass; the structural components adopt standardized modular design to the maximum extent.
[0044] Through the above structure, this new type of overpass not only effectively plans and integrates process pipelines and equipment, but also breaks the previous square and monotonous image of overpasses.
[0045] The space above the suspended ceiling 7 and below the horizontal floor 8 can be used as a process integrated pipeline corridor, and at the same time, installation space for floor heating equipment can be provided as needed; the space between the top curved steel beam and the suspended ceiling can be used as fire water pipes and HVAC pipes, and at the same time, cable trays and control cable equipment are arranged under the horizontal floor 8.
[0046] In this embodiment, a power storage module 11 is further provided below the horizontal floor 8 to meet the needs of self-use and external supply.
[0047] like Figure 5 As shown, a maintenance curtain wall 13 is provided on the surface of the upper curved structure 1 and the lower curved structure 2. The maintenance curtain wall 13 adopts an integral unitized curtain wall and is wrapped around the outer side of the overpass body.
[0048] In this embodiment, the protective curtain wall 13 adopts BIPV photovoltaic glass or LOWE energy-saving glass, and the protective system forms a closed system to disperse rainwater.
[0049] Through the above structure, the internal space is made safe and unobstructed, the landscape view is better, and it is effectively combined with BIPV photovoltaic glass or LOWE energy-saving glass.
[0050] In this embodiment, the longitudinal support members can be in various forms such as steel columns, plane tube trusses, three-dimensional tube trusses, etc. according to the height of the connecting overpass.
[0051] In this embodiment, the lower curved structure is provided with an armrest, and an electric blind 12 is provided below the armrest.
[0052] In this embodiment, the welding spacing between the steel beams is 8 mm.
[0053] It should be noted that the curved surface structure in this embodiment can be a semicircular structure, or other curved structures, which can be set according to the actual scenario.
[0054] This new overpass utilizes a tubular truss system that integrates the main structure with the floor structure, resulting in improved overall structural stability and seismic resistance. Compared to conventional multi-story and split steel truss systems, this reduces steel usage, significantly lowering construction costs. The tubular truss design also facilitates later renovations, reducing costs.
[0055] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
