Description

Technical Field

[0001] The utility model relates to the technical field of structural engineering steel structures, in particular to a radial fish-belly type conversion truss. Background Art

[0002] With the development of society and the advancement of science and technology, people's demand for buildings has shifted from simple functionality to diversification, especially for public buildings and commercial buildings. These buildings not only need to meet people's basic needs, but also give people a beautiful visual enjoyment, and at the same time have a large span of column-free space to meet the needs of various commercial activities. As an important structural form for realizing the conversion of building space, steel structure conversion trusses play a vital role in the stability, bearing capacity and space utilization of building structures.

[0003] However, it still has the following disadvantages in actual use:

[0004] Traditional conversion trusses are usually arranged orthogonally. Although this layout is simple and practical, it is difficult to meet the pursuit of artistry and smooth appearance in modern architecture. When the position of the structural column is along the arc line, or the number of structural columns is the cardinality, the arrangement and positioning of the orthogonal truss becomes more complicated, which imposes many restrictions on the structural arrangement and building layout. In addition, if the truss support adopts a rigid connection method, the truss will be subjected to a large bending moment, and higher-strength materials and larger-section components will be required to meet the load-bearing requirements. This will further increase the weight and cost of the entire structure, which is not conducive to creating a light and transparent architectural space effect. Therefore, it is necessary to explore new forms of conversion trusses.

[0005] Therefore, a new radial fish-belly conversion truss is proposed to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a radial fish-belly conversion truss to achieve the unification of architectural aesthetics and functionality while meeting the requirements of bearing capacity, thereby realizing a large-span column-free space.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The utility model is a radial fish-belly conversion truss, comprising:

[0009] A radial fish-belly truss, wherein a support end solid web section is fixed on the outside of the radial fish-belly truss, a lattice-type reinforced transition section is fixed on the rear side of the support end solid web section, and a radial fish-belly truss diagonal web member is welded to the upper chord of the radial fish-belly truss;

[0010] A ring-shaped secondary truss, wherein a ring-shaped secondary truss web member is fixed on the top of the ring-shaped secondary truss;

[0011] Truss support. Furthermore, radial fish-belly truss web bars are welded to the sides of the radial fish-belly truss diagonal web bars, radial fish-belly truss lower chord bars are welded to the bottom of the radial fish-belly truss web bars, and radial fish-belly truss upper chord bars are welded to the top of the radial fish-belly truss web bars. The radial fish-belly truss lower chord bars can be changed into straight, broken line or parabola according to the appearance of the building.

[0012] Furthermore, the lower chord of the annular secondary truss web is fixed with the lower chord of the annular secondary truss, and the upper chord of the annular secondary truss web is fixed with the upper chord of the annular secondary truss.

[0013] Among them, the annular secondary truss is arranged between the radial fish-belly trusses and connected to the radial fish-belly trusses. The annular secondary truss is a parallel chord truss or a hollow truss. A plane truss or an arc truss can be used according to the requirements of the building form. The web bars of the annular secondary truss are hingedly connected or fixedly connected to the upper chord bars and the lower chord bars of the annular secondary truss. The annular secondary truss is one or more.

[0014] Furthermore, the radial fish-bellied truss is radially hingedly connected to the truss support, the support end has a solid cross-section, and a lattice-type reinforced steel plate transition section is between the truss and the solid cross-section. The radial fish-bellied truss and the truss support can be connected using, including but not limited to, finished supports or pins.

[0015] Further, it also includes a truss center node;

[0016] The periphery of the central node of the truss is provided with upper and lower chord flange special-shaped steel plates, a central circular tube is welded and fixed inside the central node of the truss, a reinforcing steel plate at the junction of the circular tube and the chord flange is welded at the lower end of the outer surface of the central circular tube, an oblique web along the radial direction of the fish-belly truss is fixed outside the central circular tube, and the upper and lower chord webs are located between the upper and lower chord flange special-shaped steel plates.

[0017] Furthermore, there are seven solid cross-sections at the support end, which are equidistantly distributed on the outer surface of the central node of the truss, and the center line of the radial fish-bellied truss is collinear with the center line of the truss support.

[0018] Furthermore, the cross-section types of the upper chord, lower chord and web of the radial fish-bellied truss are box-shaped, H-shaped or round tube-shaped, and the radial fish-bellied truss and the annular secondary truss are connected with the concrete floor slab by bolts and work together to form a combined structure. On the one hand, the bearing capacity and rigidity of the steel beam are improved, saving the cost; on the other hand, the restraining effect of the floor slab on the upper chord is increased, improving the stability of the structure.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The utility model has a good structural system integrity, high rigidity, large bearing capacity, clear force transmission, and meets the requirements of building safety and stability.

[0021] Second, based on the beneficial effect 1, it has excellent functionality and provides flexible spatial layout and variable architectural forms for buildings. This structural system can be flexibly adjusted and changed according to different needs to meet the requirements of modern architecture for spatial layout and architectural form. At the same time, this structural system can also provide buildings with variable appearance effects, enhancing the artistic quality and spatial expression of the building.

[0022] 3. Based on the second beneficial effect, the overall height is small and the cross-section of the components is small, which can reduce the waste of materials. This structural system can effectively reduce the weight and cost of the building, while reducing the consumption and waste of natural resources. In addition, the construction difficulty of this structural system is relatively low, which can shorten the construction period and improve the construction efficiency.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 4 , Figure 6 As shown, the utility model discloses a radial fish-belly conversion truss structure system, comprising:

[0039] A radial fish-belly truss 1, a support end solid web section 1-1 is fixed to the outside of the radial fish-belly truss 1, a lattice-type reinforced transition section 1-2 is fixed to the rear side of the support end solid web section 1-1, and the upper chord of the radial fish-belly truss 1 is connected to a radial fish-belly truss diagonal web member 1-6;

[0040] A ring-shaped secondary truss 2, with a ring-shaped secondary truss web member 2-3 fixed on the top of the ring-shaped secondary truss 2;

[0041] Truss support 4.

[0042] like Figure 3 As shown, the radial fish-belly truss is composed of a support end solid web section 1-1, a lattice-type reinforced steel plate transition section 1-2, a radial fish-belly truss upper chord 1-3, a radial fish-belly truss lower chord 1-4, a radial fish-belly truss web member 1-5, a radial fish-belly truss diagonal web member 1-6, and a stiffening steel plate. The radial fish-belly truss web member 1-5, the radial fish-belly truss diagonal web member 1-6, the radial fish-belly truss upper chord 1-3, and the radial fish-belly truss lower chord 1-4 are hingedly connected or fixedly connected. The radial fish-belly truss lower chord 1-4 is changed into a straight line, a broken line, or a parabola according to the shape of the building. The cross-sections of all the above-mentioned components are H-shaped, box-shaped, or round tubes.

[0043] like Figure 4 As shown, the annular secondary truss 2 includes an annular secondary truss upper chord 2-1, annular secondary truss lower chord 2-2, annular secondary truss web 2-3 and stiffening steel. The annular secondary truss web 2-3 is hingedly connected or fixedly connected to the annular secondary truss upper chord 2-1 and the annular secondary truss lower chord 2-2.
