[0002] The selection of the structural form of the room for large-span buildings, such as single-story, large-span and ultra-high space industrial buildings, is the focus of research in the industry. Such structures usually adopt a lattice building structure based on truss assembly, and an inverted triangle truss is used on the roof of the building. Large-span building structures will withstand more and stronger earthquake and wind loads than other conventional structures, which puts higher requirements on the stability of large-span building structures, especially the connection stability between beams and columns. However, existing building structures, such as patent document CN109372269A, only support and weld the roof by hoisting and mounting it directly above the column. If an inverted triangle truss is used to construct the roof, then one of the side edge tie rods of the inverted triangle truss faces the column, the contact area between the roof and the column is small, and there are few connection points. This will cause the connection between the roof and the column to be unstable and cannot meet the stability requirements.

[0003] Therefore, how to increase the stability of buildings has become an urgent problem to be solved by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to better illustrate the present application, numerous specific details are provided in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0029] The present application provides a lattice building structure based on truss assembly, including a first column 100 , a first reinforcement portion and more than two first triangular trusses 300 .

[0030] The axial directions of two or more first triangular trusses 300 are consistent, and the two or more first triangular trusses 300 are adjacently distributed along the width direction thereof, the first reinforcement portion includes a first connecting portion 210, and the first connecting portion 210 includes a first connecting member, and a first connecting member is provided between two adjacent first triangular trusses 300, and opposite ends of the first connecting member are respectively connected to the side walls of the two adjacent first triangular trusses 300, and both axial ends of the first triangular trusses 300 are connected to columns;

[0031] One axial end of the first column 100 is connected to the first triangular truss 300, and a first compression rod 310, a second compression rod 320 and a tension rod 330 are provided at three side edges of the prism structure of the first triangular truss 300. The first compression rod 310 and the second compression rod 320 are both connected to the radial side wall of the first column 100, and the tension rod 330 is provided with a second reinforcement part 340 at both ends of the axial direction of the first triangular truss 300. The second reinforcement part 340 is Y-shaped, and the two opposite ends of the Y-shape of the second reinforcement part 340 are respectively connected to the side wall of the first column 100, and the remaining end of the Y-shape of the second reinforcement part 340 is connected to the tension rod 330;

[0032] The other axial end of the first column 100 protrudes out of the side wall of one end of the first triangular truss 300 provided with a tension rod 330 and is fixed to the ground.

[0033] The present application forms a roof of the building by connecting the first triangular truss 300 and the first reinforcement part. The roof is supported off the ground by connecting the first column 100 with the first triangular truss 300 and the ground, forming an internal space of the building under the roof.

[0034] Among them, the two tension rods of the first triangular truss 300 are toward the top of the roof, which are compression rods; one tension rod is toward the bottom of the roof, which is the tension rod 330. On the basis of ensuring the compression and tension capacity of the roof and the building, the steel consumption of the truss can be reduced, the stability of the building can be ensured, and the stability requirements of the large-span and ultra-high structure can be met. In addition, the end of the tension rod 330 of the triangular truss is divided into two by the second reinforcement part 340, and is firmly connected to the side wall of the column in a triangular shape. The triangle has stability and can improve the connection stability between the first triangular truss 300 and the first column 100. Compared with the existing building, only the roof is erected on the upper end of the column. If an inverted triangular truss is used, the contact area is small, the connection points are few, and the connection between the roof and the column is unstable. In this application, the axial end of the triangular truss is fixed to the radial end side wall of the first column 100, avoiding the problem of unstable connection caused by the small contact area. And the second reinforcement part 340 increases the connection node, forming a more stable triangular connection structure.

The maximum stress ratio of the first connection occurs in the end diagonal web, which is 0.55 and is controlled by the stability check. The maximum stress ratio of the third connection occurs in the end diagonal web, which is 0.66 and is controlled by the stability check. The maximum stress ratio of the inter-column support occurs in the end diagonal web, which is 0.40 and is controlled by the stability check.

[0066] Deformation calculation: The maximum vertical displacement of the triangular truss beam under 1.0 dead load + 1.0 live load is -30mm, and the ratio to the span is 1 / 1017, which is less than the limit value L / 300 of the "Standard for Design of Steel Structures" GB50017-2017. Under 1.0 dead load + 0.5 live load + 1.0 earthquake, the maximum displacement of the top of the column in the X direction is 7mm, and the maximum displacement of the top of the column in the Y direction is 11.7mm. Under the action of +Y wind, the maximum displacement of the top of the column is 52.1mm, and the maximum displacement of the top of the column in the -Y direction is 50.0mm. Under the action of +X wind, the maximum displacement of the top of the column is 3.5mm, and the maximum displacement of the top of the column in the -X direction is 3.1mm. From the calculation comparison of multiple schemes, it can be seen that since the overall structure adopts lattice columns, truss beams, truss tie rods, etc., the structure has a light weight and a small response under earthquake action. Ultimately, the wind load controls the lateral deformation of the structure.

[0067] Eigenvalue buckling analysis: Linear buckling analysis is performed with (1.0 dead load + 1.0 live load) as the load condition. The 1st, 2nd, and 5th order buckling modes are all out-of-plane buckling of the plane truss support between lattice columns, and the 3rd, 4th, and 6th orders are out-of-plane buckling of the main transverse truss of the roof truss. The lattice columns did not buckle in the first 50 orders. The first order buckling mode is the local instability of the plane truss support between lattice columns. The load factor is 37, that is, the maximum buckling load is: 37×(1.0 dead load + 1.0 live load), and the critical coefficient of the eigenvalue buckling analysis is λ b The results of the eigenvalue buckling analysis are shown in the following table:
