Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and in particular to a building structure system. Background Art

[0002] In traditional structures, the structure obtains its rigidity from geometry and materials. This type of structure that mainly obtains its rigidity from geometry and materials is called a rigid structure. Rigid structures do not require prestressing to maintain stability. Rigid structures have been widely used due to their advantages such as reasonable force, simple calculation, high rigidity, material saving, single rod member, and easy production and installation. Among the many spatial structural forms, the steel truss structure is a typical rigid structure. Steel trusses are widely used. For example, in the roofs (roof trusses, etc.) of industrial and civil buildings and crane beams (i.e., crane trusses), bridges, cranes (their towers, beams or arms, etc.), hydraulic gates, and offshore oil platforms, steel trusses are often used as the main components of the load-bearing structure. Various types of steel grids that are commonly used in the roof structures of large-span public buildings are spatial steel trusses.

[0003] However, spatial steel trusses also have drawbacks that cannot be ignored. They are heavy, have large cross-sections, require a lot of steel, have low load-bearing efficiency, have poor boundary adaptability, are weak in corrosion resistance, and have high maintenance costs. Furthermore, they require a specific grid structure, often failing to meet the requirements of complex architectural designs. Furthermore, spatial steel trusses block a large area and lack transparency, significantly impacting daylighting and making them difficult to use in buildings with high transparency requirements. Steel trusses (grid frames) often struggle to meet the aesthetic demands of modern architecture when applied to buildings with exposed structures. Summary of the Invention

[0038] The specific embodiments of the present invention will be described in more detail below in conjunction with the schematic diagrams. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the attached drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0039] Figure 1 is a schematic diagram of a building structure system according to an embodiment of the present invention, Figure 2 is a schematic diagram of the upper chord structural surface, outer ring beam and inner ring beam of a building structure system according to an embodiment of the present invention, Figure 3 is a front elevation schematic diagram of a building structure system according to an embodiment of the present invention. Please refer to Figure 1 、 Figure 2 and Figure 3, an embodiment of the present invention provides a building structure system. Taking a flat roof as an example, the structure system includes an outer ring beam 01, an inner ring beam 02, an upper chord structural surface 03, a lower chord structural surface 21, and multiple struts 05. It can be understood that both the outer ring beam 01 and the inner ring beam 02 are annular. In this embodiment, there is no limitation on the shape, and both can be regular annular shapes, such as circular or polygonal annular shapes. Of course, they can also be irregular annular shapes. The inner ring beam 02 is coplanar with the outer ring beam 01, and the inner ring beam 02 is located within the outer ring beam 01. The upper chord structural surface 03 is planar, and the upper chord structural surface 03 includes multiple upper chord bars 20. The upper chord structural surface 03 is rigidly connected coplanarly between the outer ring beam 01 and the inner ring beam 02. That is, the connection mode between the upper chord bar 20 connected to the outer ring beam 01 and the outer ring beam 01 is rigid connection, and the connection mode between the upper chord bar 20 connected to the inner ring beam 02 and the inner ring beam 02 is rigid connection; the ends of the multiple upper chord bars 20 are connected to make the upper chord structural surface in a grid shape, that is, the upper chord structural surface includes multiple polygonal grids. Any three pairwise adjacent upper chord bars 20 are rigidly joined to form a first junction end M. It can be understood that the grid of the upper chord structural surface is formed by multiple upper chord bars connected end to end. The material of the upper chord bar is aluminum alloy. Optionally, the upper chord bar 20 is an aluminum alloy profile with a closed cross-section or an open cross-section. The lower chord structural surface 21 is curved, and the lower chord structural surface 21 connects the outer ring beam 01 and the inner ring beam 02. The lower chord structural surface 21 includes multiple lower chord tie rods 04. The ends of the multiple lower chord tie rods 04 are hinged to each other to make the lower chord structural surface 21 in a grid shape, that is, the lower chord structural surface 21 includes multiple polygonal grids. The grid of the lower chord structural surface 21 is formed by multiple lower chord tie rods 04 connected end to end. That is, the lower chord tie rods 04 are hinged to form a polygonal tension ring, and multiple polygonal tension rings are connected to form a spatial lower chord curved surface. The lower chord tie rods 04 within the same tension ring may or may not be coplanar. Any three pairwise adjacent lower chord tie rods meet to form a second junction end N. The multiple first junction ends M of the upper chord structural surface and the multiple second junction ends N of the lower chord structural surface 21 correspond one by one, and the normal projection of the second junction end N on the horizontal plane coincides with the first junction end M; all the first junction ends M and the second junction ends N are three-bar intersections. It can be understood that the grids of the upper chord structural surface and the lower chord structural surface 21 can be arbitrary polygons, such as triangles, quadrilaterals, pentagons, etc. Therefore, such a grid structure can be applicable to any irregular boundary conditions. In addition, the connection mode between the lower chord tie rod 04 connected to the outer ring beam 01 and the outer ring beam 01 is hinged, and the connection mode between the lower chord tie rod 04 connected to the inner ring beam 02 and the inner ring beam 02 is hinged. The two ends of the strut 05 are respectively connected to the first junction end M and the second junction end N, and the corresponding three upper chord bars 20 and the corresponding three lower chord tie rods 04 are all hinged to the strut 05;

[0040] Preferably, the lower chord tie rod 04 is made of alloy steel material, and the strut 05 is made of round steel pipe. Therefore, the lower chord tie rod 04 and the strut 05 have the advantages of small cross-section and high strength, little light shielding, and improved permeability of the entire roof.

[0041] With the above configuration, the normal projection of the first intersection end M of the upper chord structural surface 03 and the corresponding second intersection end N of the lower chord structural surface 21 on the horizontal plane coincides. This can make the normal projection of the upper chord rod 20 of the upper chord structural surface 03 and the lower chord tie rod 04 of the corresponding lower chord structural surface 21 on the horizontal plane coincide. Furthermore, the normal projections of the grids of the upper chord structural surface and the lower chord structural surface 21 on the horizontal plane coincide. Thus, when the building structure system of the present invention is viewed from above, the effect is transparent. The lower chord tie rods 04 and the upper chord rods 20 correspond one by one, without the visual impact of the lower chord tie rods 04 passing through the grids of the upper chord structural surface 03, without the problem of light shielding, with good lighting, and the entire roof has a light and transparent architectural effect, which can meet the requirements of buildings with high permeability requirements. On the one hand, the upper chord rods 20 of the upper chord structural surface 03 are rigidly connected structures, and the lower chord tie rods 04 and struts 05 are both hinged members at both ends. The lower chord tie rods 04 are hinged to each other to form a grid-shaped polygonal tension ring. The polygonal tension ring forms a space curved surface, forming a spatial continuous tie rod form, and its form is obtained by integral form finding. The boundary conditions and span are the main factors affecting its form. The purpose of controlling the form of the lower chord tie rod 04 is to make the vertical deformation of the upper chord of the structure under dead load a small deformation, and the initial geometric basic form remains unchanged. Thus, the aluminum alloy upper chord structural surface 03, outer ring beam 01, inner ring beam 02, lower chord tie rod 04 and strut 05 together form a cable-strut structure, which can span a large space, has strong boundary adaptability, and can be applied to large-span space structures with any boundary conditions, having excellent mechanical properties. On the other hand, the upper chord rods 20, inner ring beam 02, and outer ring beam 01 of the present invention are all made of aluminum alloy, the lower chord tie rod 04 is made of alloy steel material, and the strut 05 is made of round steel pipe, which can give full play to the material advantages. At the same time, aluminum and steel are used. The lower chord tie rod 04 and the strut 05 have the advantages of small cross-section and high strength, so that the entire roof has a light and transparent architectural effect. Aluminum alloy materials have the characteristics of good durability, corrosion resistance, light self-weight, easy processing, maintenance-free, recyclable, etc., and have broad development prospects in the field of large public buildings. Alloy steel tie rods have a significantly improved strength compared to conventional carbon steel, and can give full play to the material strength in tension members. The structural system formed by aluminum alloy, cable, and steel structure can give full play to the performance advantages of their respective materials, can meet the requirements of complex building forms and large-space permeability, and can also adapt to the requirements of complex irregular boundary buildings.

[0042] Further, the building structure system further includes an outer support tube 07 and an inner support tube 08. The outer support tube 07 includes a plurality of vertical outer structural columns 22 arranged in sequence along the circumferential direction of the outer ring beam, and the outer structural columns 22 are hinged to the outer ring beam. The inner support tube 08 includes a plurality of vertical inner structural columns 23 arranged in sequence along the circumferential direction of the inner ring beam, and the inner structural columns 23 are hinged to the inner ring beam. In some other embodiments, the present invention may not provide the outer support tube 07 and the inner support tube 08, but directly land or support on the top of a rigid structure. Specifically, the outer ring beam 01 and the inner ring beam 02 can be directly hinged to the lower rigid structure. For example, in this embodiment, both the inner structural column 23 and the outer structural column 22 are steel structural columns.

[0043] It can be understood that the upper ends of the steel structural columns are hinged to both the outer ring beam 01 and the inner ring beam 02, and the lower ends of the steel structural columns are used for rigid connection with other structures of the house. Preferably, please refer to Figure 4 , the outer support tube 07 further includes a plurality of outer tube diaphragm beams 09, and at least one outer tube diaphragm beam 09 is rigidly connected between two adjacent outer structural columns 22. Preferably, the outer tube diaphragm beam 09 is perpendicular to the outer structural column 22. The inner support tube 08 further includes a plurality of inner tube diaphragm beams 10, and at least one inner tube diaphragm beam 10 is rigidly connected between two adjacent inner structural columns 23. Preferably, the inner tube diaphragm beam 10 is perpendicular to the inner structural column 23. The arrangement of the outer tube diaphragm beam 09 and the inner tube diaphragm beam 10 enhances the stiffness of the outer support tube 07 and the inner support tube 08. Further, both the outer tube diaphragm beam 09 and the inner tube diaphragm beam 10 are made of steel.

[0044] Preferably, please refer to Figure 10 , the inner support tube 08 is further provided with column bracings, and the column bracings are rigidly connected to the inner tube diaphragm beam 10 and / or the inner structural column 23. The column bracings include multiple groups of intersecting members 24, and the multiple groups of members 24 are vertically arranged on the inner support tube 08. Specifically, each group includes two intersecting members 24, and the members 24 connect at least two adjacent inner structural columns 23 in sequence. Of course, the members 24 can also connect the inner tube diaphragm beam 10 between the inner structural columns 23. The multiple groups of members 24 are vertically arranged in sequence and extend to both ends of the inner structural column 23. In this embodiment, multiple sets of column bracings are provided on the inner support tube 08. In this way, the ability of the building to resist horizontal forces is enhanced, and the cross-sectional area of the outer structural column 22 can be significantly reduced. Moreover, the outer structural column 22 mainly bears vertical loads, and the outer support tube 07 does not need to be provided with column bracings, making the building's exterior facade transparent and beautiful.

[0045] For example, the upper end of the strut 05 is hinged at the intersection of the corresponding three upper chord members 20 (i.e., the first intersection end M). Specifically, please refer to Figure 5 and Figure 6, a second connecting ear plate 12 is provided at the intersection of the upper chord 20, and two first reinforcing ribs 18 are provided on the second connecting ear plate 12. The first reinforcing ribs 18 are, for example, triangular, and are used to increase the strength of the second connecting ear plate 12. At the upper end of the strut 05, two parallel first connecting ear plates 11 are provided. Each first connecting ear plate 11 is provided with three parallel second reinforcing ribs 19. The second reinforcing ribs 19 are, for example, triangular, and are used to increase the strength of the first connecting ear plate 11. The first connecting ear plate 11 is parallel to the second connecting ear plate 12 and is located between the two second connecting ear plates 12. The first connecting ear plate 11 and the second connecting ear plate 12 are connected by a spherical plain bearing 17 to achieve a two-way hinged connection.

[0046] Further, please refer to Figure 7 and Figure 8 , the building structure system further includes a third connecting ear plate 13. The third connecting ear plate 13 is provided at the second intersection end N. The third connecting ear plate 13 is provided with three tie rod connecting parts 131. The tie rod connecting parts 131 are hinged to the tie rod fork ears 14 provided at the ends of the lower chord tie rod 04. Specifically, the three tie rod connecting parts 131 are all plate-shaped. The tie rod fork ear 14 has two parallel extension arms. The tie rod connecting parts 131 are located between the two extension arms of the tie rod fork ear 14 and are hinged to the extension arms. The specific hinging method is not limited. In this embodiment, the pin hinge method is adopted. In this embodiment, the third connecting ear plate 13 is made of steel.

[0047] Preferably, the building structure system includes a plurality of diagonal web members 06. The diagonal web members 06 are located between at least some adjacent struts. One end of the diagonal web member 06 is hinged to the upper chord, and the other end of the diagonal web member 06 is hinged to the lower chord tie rod. The diagonal web members 06 can be locally provided according to the boundary conditions, rise and force requirements. The diagonal web members 06 can effectively improve the structural stiffness. The stiffness of the roof structure can be increased by increasing the number of diagonal web members 06, and the stiffness of the roof structure can be reduced by reducing the number of diagonal web members 06. Therefore, by setting the number of diagonal web members 06, the out-of-plane stiffness of the roof structure can be controlled, and then the magnitude of the deformation of the roof structure can be controlled.

[0048] Further, two diagonal web members 06 are provided between at least some adjacent struts 05, and the diagonal web members are inclined relative to the struts. One end of each of the two diagonal web members 06 is hinged to the same location of the upper chord (such as the middle part of the upper chord), and the other ends of the two diagonal web members 06 are respectively hinged to the corresponding second intersection ends N of the two struts 05. That is, both ends of the diagonal web member 06 are hinged connections. The force characteristics of the hinge are that it can transmit axial force, can transmit shear force but cannot transmit torque. In order not to transmit bending moment, both ends of the diagonal web member 06 are hinged.

[0049] The diagonal web member 06 is hinged at the intersection with the lower chord tie rod 04. Specifically, in this embodiment, please refer to Figure 9, a web member connecting portion 133 is provided on the third connecting ear plate 13. The web member connecting portion 133 is plate-shaped. Two mutually parallel fourth connecting ear plates 16 are provided at the end of the diagonal web member 06. The web member connecting portion 133 is located between the two fourth connecting ear plates 16 and is hinged to the fourth connecting ear plates 16. One end of the two diagonal web members 06 converges and is hinged on the upper chord 20. Specifically in this embodiment, a sixth connecting ear plate is provided on the upper chord 20, and an ear plate corresponding to the sixth connecting ear plate is provided at the end of the diagonal web member 06, so as to be hinged to the sixth connecting ear plate. In this embodiment, the diagonal web member 06 is, for example, a circular steel pipe.

[0050] Furthermore, please refer to Figure 8 and Figure 9 , a strut connecting portion 132 is also provided on the third connecting ear plate 13. The strut connecting portion 132 is hinged to the end of the strut 05. Specifically, the strut connecting portion 132 is plate-shaped. Two mutually parallel fifth connecting ear plates 15 are provided at the lower end of the strut 05. The strut connecting portion 132 is located between the two fifth connecting ear plates 15 and is hinged to the fifth connecting ear plates 15.

[0051] In this embodiment, the strut 05, the diagonal web member 06, and the lower chord tie rod 04 are all two-end hinged members. The hinged manner makes the flexibility of the roof structure relatively large, capable of absorbing the impact force of natural disasters such as earthquakes, reducing the vibration response of the structure, and is very suitable for places that need to consider the earthquake influence such as high-rise buildings and long-span structures. It is also applicable to buildings that need to pre-arch the upper chord roof during construction, and can have a certain deformation amount to ensure that the upper chord roof remains flat under the combination of dead load and live load, etc.

[0052] The structural system of the present invention is applicable to single-slope roofs or flat roofs. During construction, it is necessary to pre-arch the upper chord roof, that is, to pre-arch the aluminum alloy upper chord structure surface. The pre-arching can be achieved by adjusting the initial length of the lower chord tie rod 04 to ensure that the aluminum alloy upper chord structure surface remains flat under the combination of dead load and live load, etc. Under reliable boundary support conditions, the present invention will form a self-balanced structural system in which the aluminum alloy upper chord structure surface is compressed, the lower chord tie rod 04 is tensioned, and the strut 05 is compressed. The diagonal web member 06 may be compressed or tensioned.
