Technical Field

[0001] The present application relates to the technical field of steel structure trusses, and in particular to a truss structure. Background Art

[0002] Steel truss structures are a common structural form in modern industrial buildings. They are widely used due to their light weight, factory-fabricated construction, quick installation, short construction cycles, and excellent seismic resistance. However, steel structure construction places high demands on the environment. According to design specifications, the ambient temperature range for steel structure construction must be within ±25°C, and the truss closure and welding must be performed within an ambient temperature range of 5°C to 15°C.

[0003] When the truss hoisting period is from April to August, especially from June to August, the outdoor ambient temperature exceeds 15°C. Therefore, it is difficult to ensure that the hoisting and closing process will be carried out within the specified period of time within the temperature range of 5°C to 15°C. Utility Model Content

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a truss structure.

[0006] Optionally, the lower end of the limiting plate is fixedly connected to the span column, and the limiting plate abuts against the support assembly.

[0007] Optionally, the support assembly includes a spherical support and a connecting piece, the spherical support is arranged on the span side column and movably connected to the span side column, the spherical support and the connecting piece are fixedly connected, and the connecting piece is used to connect the spherical support and the main truss.

[0008] Optionally, the height of the limiting plate is not lower than the height of the spherical support.

[0009] Optionally, a connecting beam is further included. There are multiple main trusses, and the connecting beam is arranged between two adjacent main trusses. The limiting plate on one side of the connecting beam is arranged between the spherical support and the connecting beam.

It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0029] In the description of the embodiments of the present application, "multiple" and "several" mean more than two (including two), unless otherwise clearly and specifically defined.

[0030] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] According to some embodiments of the present application, referring to Figures 1 to 4 As shown. Among them, Figure 1 This is a schematic plan view of the truss structure according to an embodiment of the present application. Figure 2 This is a schematic plan view of the left side column of the truss structure of an embodiment of the present application. Figure 3 This is a schematic plan view of the right span side column of the truss structure of an embodiment of the present application. Figure 4This is a schematic structural diagram of the support assembly of the embodiment of the present application. The truss structure of the embodiment of the present application includes: a span side column 1, a main truss 2, a support assembly 3 and a limit plate 4. There are two span side columns 1, and the two span side columns 1 are symmetrically arranged; the main truss 2 is installed between the two span side columns 1; the support assembly 3 is arranged between the main truss 2 and the span side column 1, the support assembly 3 is fixed to the main truss 2, and the support assembly 3 is movably connected to the span side column 1; the limit plate 4 is arranged on both sides of the support assembly 3, so that the support assembly 3 can only move in a direction parallel to the main truss 2. The lower end of the limit plate 4 is fixedly connected to the span side column 1, and the limit plate 4 is against the support assembly 3.

[0032] Specifically, the limiting plate 4 and the support assembly 3 are in contact with each other at both sides of the limiting plate 4 and the support assembly 3 . It is only necessary to ensure that the support assembly 3 can slide between the two limiting plates 4 without retaining too much space.

[0033] Since the construction of steel structures has high requirements on the environment. According to the design specifications, the ambient temperature difference range for steel structure construction is ±25°C, and the steel trusses are constructed between an atmospheric temperature of 5°C and 15°C when they are closed and welded. However, when the truss hoisting period is from April to August, especially from June to August, the outdoor ambient temperature exceeds 15°C. In order to ensure that the hoisting and closing is carried out between 5°C and 15°C within the established construction period, the support assembly 3 is movably connected to the span column 1, and limit plates 4 are set on both sides of the support assembly 3. The support assembly 3 can only move in a direction parallel to the main truss 2, so that the main truss 2 can only move in a direction parallel to the main truss 2 under temperature stress. After the enclosure structure is closed and the heating reaches a temperature between 5-15°C, the support assembly 3 is firmly welded to the span column to ensure the safety of the main truss structure, solving the problem that construction cannot be carried out at the current temperature.

[0034] According to some embodiments of the present application, reference Figures 4 to 6 As shown, Figure 5 This is a front view of the support assembly of an embodiment of the present application. Figure 6 This is a top view of the support assembly of an embodiment of the present application. Support assembly 3 includes a spherical support 31 and a connector 32. Spherical support 31 is mounted on and flexibly connected to span column 1. Spherical support 31 and connector 32 are fixedly connected, connecting spherical support 31 to main truss 2. The height of stop plate 4 is no less than that of spherical support 31.

[0035] Specifically, the movable connection between the spherical support 31 and the span side column 1 means that after the high-altitude welding operation of the main truss 2 of each span is completed, a reserved weld 8 is set between the span side column 1 and the spherical support 31, so that the spherical support 31 can slide between the two limit plates 4.

[0036] The spherical support 31 and the main truss 2 are fixedly connected by the connector 32. The size of the connector 32 can be selected to match the distance between the main truss 2 and the spherical support 31, so it has high flexibility in construction. At the same time, the connector 32 is smaller in size than other structures. Connectors 32 of various sizes can be prefabricated in advance by the factory. Connectors 32 of appropriate sizes are selected for welding during construction, which can reduce manufacturing costs and usage costs. A reserved weld 8 is set between the span column 1 and the spherical support 31, and the spherical support 31 can slide between the two limit plates 4. Since the connector 32 and the main truss 2 are connected at the top of the spherical support 31, the volume and weight of the main truss 2 are relatively large, so the height of the limit plate 4 needs to be no lower than the height of the spherical support 31 to ensure that the spherical support 31 will not roll over when sliding between the two limit plates 4, thereby ensuring the stability of the overall structure.

[0037] According to some embodiments of the present application, reference Figures 4 to 6 The truss structure further includes a connecting beam 5. Multiple main trusses 2 are provided. The connecting beam 5 is provided between two adjacent main trusses 2. A limiting plate 4 on one side of the connecting beam 5 is provided between the spherical support 31 and the connecting beam 5. The width of the limiting plate 4 on one side of the connecting beam 5 is not less than the width of the cross section of the connecting beam 5.

[0038] Truss structures are often used in buildings with large spans and require multiple main trusses 2 arranged parallel and spaced apart in a single direction. Adjacent main trusses 2 are connected by connecting beams 5. A stop plate 4, located on one side of the connecting beam 5, is positioned between the spherical support 31 and the connecting beam 5. Because the spherical support 31 inevitably rubs against the stop plate 4 during movement, the stop plate 4 is designed to be at least as wide as the cross-sectional width of the connecting beam 5 to prevent friction and ensure overall structural stability.

[0039] In some instances, reference Figure 4 The connector 32 is provided with a plurality of reinforcing ribs 321 , which are arranged at intervals. The connector 32 is connected to the spherical support 31 by bolts 6 . The bolts 6 are located between two adjacent reinforcing ribs 321 .

[0040] The plurality of reinforcing ribs 321 provided on the connector 32 can increase the structural bearing capacity of the connector 32. At the same time, the use of bolts 6 to connect the connector 32 and the spherical support 31 facilitates on-site construction and reduces the risk of on-site welding.

[0041] refer to Figure 2 and Figure 3 A support plate 7 is provided on the span side column 1 , and the lower end portion of the main truss 2 is placed on the support plate 7 .

[0042] A support plate is set on the span side column 1, and the lower end of the main truss 2 is placed on the support plate 7. The support plate 7 can provide support for the main truss 2 and reduce the risk of the main truss 2 falling. At the same time, the use of a built-up connection method facilitates construction and improves construction efficiency.

[0043] The working principle of the truss structure will be introduced in detail below.

[0044] Since the construction of steel structures has high requirements on the environment. According to the design specifications, the ambient temperature difference range for steel structure construction is ±25°C, and the steel trusses are constructed between an atmospheric temperature of 5°C and 15°C when they are closed and welded. However, when the truss hoisting period is from April to August, especially from June to August, the outdoor ambient temperature exceeds 15°C. In order to ensure that the hoisting and closing is between 5°C and 15°C within the established construction period. The support assembly 3 in the truss structure in this application includes a spherical support 31 and a connector 32, wherein the spherical support 31 is movably connected to the span column 1, and a limit plate 4 is provided on both sides of the spherical support 31. The spherical support 31 can only move in a direction parallel to the main truss 2, so that the main truss 2 can only move in a direction parallel to the main truss 2 under temperature stress. After the enclosure structure is closed and the heating reaches between 5-15°C, the spherical support 31 is firmly welded to the span column 1 to ensure the safety of the main truss structure, solving the problem that construction cannot be carried out at the current temperature.
