First-class construction team, ultra-low cooperation price, looking forward to your call. Under the node load evenly distributed along the span of the triangular stage truss, the axial force of the upper and lower chord members is maximum at the end points, and the opposite is true for the axial force of the web members that gradually decreases toward the mid-span. Triangular trusses are mostly used in roof trusses with tile roofs due to the large difference in the internal forces of the chords and unreasonable material consumption. Compared with triangular trusses, trapezoidal trusses have improved rod stress conditions, and when used in roof trusses, they can more easily meet the process requirements of some industrial plants. If the upper and lower chords of a trapezoidal truss are parallel, it is a parallel chord truss. The stress of the rods is slightly worse than that of the trapezoidal truss, but the types of web rods are greatly reduced, and they are mostly used in bridges and trestles. Polygonal trusses are also called polygonal trusses. The upper chord node is located on the quadratic parabola. If the upper chord is arched, the bending moment generated by the internodal load can be reduced, but the manufacturing is more complicated. Under the action of uniform load, the shape of the truss is similar to the bending moment pattern of a simply supported beam, so the upper and lower chord axial forces are evenly distributed, the web rod axial force is small, and the material consumption is the least. It is a commonly used truss form in engineering. The open-web truss basically adopts the outer movable truss price shape of the polygonal truss, with straight lines between the upper chord nodes, no oblique web bars, and only vertical web bars connected to the upper and lower chords. The axial force distribution of the rod is similar to that of the polygonal truss, but the bending moment value of the rod end changes greatly under the action of asymmetric load. The advantage is that there are fewer rods intersecting at the nodes, and construction and manufacturing are convenient. The Shenzhen-Hong Kong-Macao International Famous Wine Exhibition will be held in Shenzhen next month. The second Shenzhen-Hong Kong-Macao International Famous Wine Exhibition, organized and hosted by Shenzhen Huajuchen Industrial Co., Ltd., will be held at the Shenzhen Convention and Exhibition Center from October to October. Based on the first edition of the exhibition, the exhibition has been expanded to a new level. The exhibition area has been increased to 10,000 square meters, and there are 2 international standard booths. When purchasing trusses, you generally need to consider these factors. During the peak period, various machines and even some special machines, such as ton forklifts, are put into use one after another. Sometimes machines are working together without interruption. At a glance, the construction site is The machines and vehicles are uneven, giving the impression of a stacked bed frame house. In this case, it is best for exhibitors to book the shipping time earlier, preferably - a week in advance. Moreover, there will be party activities and performances every night. The stage of the party will be a panoramic open assembled stage for the first time, breaking the past practice of fixing the stage at one end of the site. Set the stage in the center of the venue and set up mobile small stages around it. The entire stage is assembled using two large bronze drum stands, which can be gathered or dispersed. Each bronze drum can blossom into many small stages, forming a variety of lifelike and exquisite pictures, bringing a full range of visual impact to the audience. It also uses a variety of suspended props, lights and fireworks and other latest technologies, combined with modern multimedia visual media such as large-scale shapes and giant projections, to create a variety of colorful images that fill the entire venue, putting the entire audience in the immersive experience. In a dreamlike and beautiful realm. What factors determine the quality of exhibition trusses? There are many companies selling trusses on the market, and the products of various specifications and models are not particularly uniform. Therefore, customers have a lot of freedom when purchasing trusses. Here I would like to give some suggestions to my customers and friends, hoping to help you purchase movable trusses with real prices and good products when purchasing trusses.
