Description
技术领域technical field
本实用新型涉及建筑设备技术领域，尤其涉及一种桁架结构。The utility model relates to the technical field of construction equipment, in particular to a truss structure.
背景技术Background technique
桁架是一种将上弦筋、下弦筋和腹筋等杆状结构按照特定的排布连接形成的空间支撑结构，其能够承受拉力或者压力，充分发挥材料的作用，通过使用数量很少、质量很轻的杆状结构就获得较大的承载力。按照桁架的制作材料可以将桁架分为钢桁架、钢筋混凝土桁架、木桁架、钢与木组合桁架和钢与混凝土组合桁架等。按照桁架的形状可以将桁架分为三角形桁架、梯形桁架、多边形桁架、平行弦桁架和空腹桁架等。A truss is a spatial support structure formed by connecting rod-shaped structures such as upper chords, lower chords, and abdominal tendons according to a specific arrangement. It can withstand tension or pressure, and give full play to the role of materials. The rod-shaped structure can obtain greater bearing capacity. According to the material of the truss, the truss can be divided into steel truss, reinforced concrete truss, wood truss, steel and wood composite truss and steel and concrete composite truss. According to the shape of the truss, the truss can be divided into triangular truss, trapezoidal truss, polygonal truss, parallel chord truss and vierendeel truss, etc.
在使用桁架前，需要将桁架安装至被安装设备或者被安装结构的底板上。但是由于桁架为由上弦筋、下弦筋和腹筋搭建形成的空间结构，其底端一般包括多根下弦筋，在固定下弦筋和底板时，每一根下弦筋均需要采用单独的连接件与底板连接，这就要求在底盘上设置多个连接孔，多个连接孔的连接不仅操作复杂，且组装效率很低。此外，由于相邻连接孔的孔距需要根据对应的下弦筋的间距调整，连接孔的位置精度直接影响桁架与底板的连接强度和稳定性，因此，连接孔的位置精度要求很高，很难使用自动化设备统一打孔并安装，自动化程度低。Before using the truss, the truss needs to be installed on the bottom plate of the installed equipment or the installed structure. However, since the truss is a spatial structure formed by upper chord bars, lower chord bars, and web bars, its bottom generally includes multiple lower chord bars. When fixing the lower chord bars and the bottom plate, each lower chord bar needs to use a separate connector and the bottom plate Connection, which requires multiple connection holes on the chassis, the connection of multiple connection holes is not only complicated to operate, but also low in assembly efficiency. In addition, since the distance between adjacent connecting holes needs to be adjusted according to the spacing of the corresponding lower chord bars, the position accuracy of the connecting holes directly affects the connection strength and stability of the truss and the bottom plate. Use automated equipment to punch holes and install them uniformly, with a low degree of automation.
