Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and specifically relates to a space truss system factory building structure. Background Technology

[0002] Currently, the most commonly used factory building structure is the portal frame structure. This type of structure mainly uses columns and roof beams to form a transverse rigid frame, thereby providing lateral stiffness and resisting horizontal loads. Horizontal roof bracing is only installed at the two ends of the factory building (i.e., gable walls) and at longitudinal supports. This method has advantages such as clear force distribution and convenient construction. However, this type of structure has the following problems:

[0003] As factory building height increases, horizontal displacement under wind load becomes a major control point in structural design, especially in areas with high wind loads. In such cases, using a conventional portal frame structure requires very large column sections for calculation, while the strength required is relatively small, significantly increasing material consumption and affecting aesthetics. The main reason is that the high column height means that it is not effectively supported within its height range, resulting in an excessively large calculated length. Therefore, it is necessary to increase the cross-section to improve its stiffness and meet the calculation requirements of the specifications.

[0004] CN212957845U discloses a heavy-duty steel structure factory building system, including a steel roof truss and two rows of frame components arranged opposite each other below the steel roof truss for supporting it. The steel roof truss includes oppositely arranged longitudinal beams and multiple transverse beams arranged at intervals between the longitudinal beams. Each frame component includes two symmetrically inclined legs, with a support block at the top of each leg. The bottom of each leg is connected to a pier inserted into the ground, and multiple supports connect between the two legs. This method can resist longitudinal forces to a certain extent, but it occupies a large space, consumes a lot of engineering work, and is aesthetically unappealing, without fundamentally changing the force transmission form of the portal frame factory building structure.

[0005] CN219974026U discloses a single-story steel structure factory building, including a steel roof truss system and a gable wall system. The steel roof truss system includes an upper chord, a lower chord, and web members. The gable wall system includes wind-resistant columns, inter-column bracing, and transverse beams. The top of the wind-resistant columns is hinged or rigidly connected to the lower chord, and the base of the wind-resistant columns is hinged to the foundation. The transverse beams are hinged or rigidly connected to the wind-resistant columns. The inter-column bracing is located between the lower chord, the transverse beams, and the wind-resistant columns. This method can save a certain amount of steel, but its steel roof truss system uses upper and lower chords and web members, resulting in a large and complex roof system and high engineering costs. Utility Model Content

[0006] To address the technical problems existing in the prior art, this utility model provides a space truss system factory building structure.

[0007] This utility model provides a space truss system factory building structure, including frame columns, wind-resistant columns, roof beams, longitudinal supports, gable supports, and roof horizontal supports. The tops of the frame columns are connected to the roof beams. The wind-resistant columns are set inside the frame columns on the gable side, and the tops of the wind-resistant columns are connected to the roof beams. Longitudinal supports are set between the frame columns. Roof horizontal supports are set between the roof beams. Gable supports are set between the wind-resistant columns and the frame columns.

[0008] Preferably, it also includes frame beams, which are horizontally arranged between multiple frame columns to support the frame columns.

[0009] Preferably, longitudinal supports, gable wall supports, and roof horizontal supports can be set in one or more spans, and the specific number is determined according to factors such as the size of the factory building, local wind load, and seismic action.

[0010] Preferably, by setting horizontal roof supports, the roof system is simplified into a planar truss. The horizontal roof supports can be fully distributed on the roof or distributed in a dispersed manner. As long as the roof can form a rigid body (i.e., a geometrically invariant system) and the column tops are effectively constrained, they are all within the scope of this utility model.

[0011] Preferably, the frame columns and wind-resistant columns can be single columns or lattice columns.

[0012] Preferably, the longitudinal supports, gable supports, and roof horizontal supports are made of steel or concrete.

[0013] Preferably, the longitudinal supports, gable supports, and roof horizontal supports are made of steel structures, and their cross-sectional forms include angle steel, double angle steel, I-beams, H-beams, steel pipes, T-beams, cross steel, or lattice supports.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting up longitudinal supports, gable supports, and roof horizontal supports, the factory building forms a spatial truss system, making the wind-resistant columns and frame columns into two-way non-lateral displacement components. This significantly shortens the calculation length of the factory building columns, thereby fully leveraging the strength advantages while meeting the code requirements for the stability of the factory building columns, reducing the size of the column cross-section, saving a lot of engineering materials, and making the factory building lightweight and beautiful.

[0016] 2. The roof system is simplified into a planar truss, forming a spatial truss system with the longitudinal and gable walls of the factory building. This reduces the number of upper and lower chords, web members, and other members on the roof, making the roof lightweight and simple. While saving materials, it also reduces the self-weight, thereby reducing the overall height of the factory building while ensuring the effective usable height of the factory building.

[0023] The present invention will now be described in detail with reference to the accompanying drawings:

[0024] like Figure 1 As shown, this utility model includes frame columns 1, wind-resistant columns 2, roof beams 3, longitudinal supports 4, gable wall supports 5, roof horizontal supports 6, and frame beams 7. The tops of the frame columns 1 are connected to the roof beams 3; the wind-resistant columns 2 are located inside the gable-side frame columns 1, and their tops are connected to the roof beams 3; longitudinal supports 4 are installed between the frame columns 1; roof horizontal supports 6 are installed between the roof beams 3; gable wall supports 5 are installed between the wind-resistant columns 2 and the frame columns 1; and frame beams 7 are horizontally installed between multiple frame columns 1. The longitudinal supports 4, gable wall supports 5, and roof horizontal supports 6 constitute the lateral force resisting system of this factory building structure.

[0025] A continuous horizontal roof support 6 is installed in the roof structure to form a roof planar truss system, making it equivalent to a rigid roof. Gable supports 5 are installed at the gables to restrict the lateral movement of the roof along the factory building. Longitudinal supports 4 are installed in the factory building to restrict the longitudinal movement of the roof along the factory building. Through the constraints of the gable supports 5 and the longitudinal supports 4, the roof can provide effective restraint for the factory building columns. Therefore, the roof structure can be equivalent to a support, restricting the column top displacement of the factory building to meet the relevant standard specifications.

[0026] Figure 2 , Figure 3 , Figure 4 , Figure 5The diagram illustrates four arrangements of horizontal roof supports. The key to this invention lies in achieving the desired roof planar truss structure. The horizontal roof supports should be determined based on design conditions such as the number of transverse spans and longitudinal length of the building, while also considering aesthetic appeal. Any arrangement of the horizontal supports that allows the roof to form a rigid body (i.e., a geometrically invariant system) will satisfy the requirements of a spatial truss system.

[0027] The above descriptions of the embodiments are only intended to help understand the principles of the embodiments of this utility model; those skilled in the art should understand that modifications and alterations can be made to the specific implementation methods and applications without departing from the protection scope and spirit of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.

[0028] A further technical feature of this utility model is that, in addition to bearing the wind load of the gable wall, the wind-resistant column also serves to connect the gable wall frame columns, forming a rigid body (i.e., a geometrically invariant system) through the gable wall support.
