Erfeng Stage Truss (stage quality must be guaranteed) Zhengzhou Jining Erfeng Stage Truss Truss Factory warmly reminds you that it is a spatial structure composed of multiple rods connected through nodes according to a certain grid form. It has the advantages of space stress, light weight, high stiffness and good seismic resistance, and can be used as roofs for stadiums, theaters, exhibition halls, waiting halls, stadium stand awnings, aircraft hangars, two-way large column spacing workshops and other buildings. The disadvantage is that there are a large number of rods that meet at the nodes, and the production and installation are more complicated than a flat structure. Classified grid structures can be divided into double-layer plate grid structures, single-layer and double-layer shell grid structures according to different shapes. The rods of plate type grids and double-layer shell type grids are divided into upper chords, lower chords and web poles, which mainly bear tension and pressure. The poles of single-layer shell type grids not only bear tension and pressure, but also bear bending force. moment and shear force. At present, most grid structures in China adopt plate grid structures. Grid structure plate grid structure is mainly divided into three categories according to its composition form. The first type is composed of a plane truss system, including two-way orthogonal orthogonal grid, two-way orthogonal and diagonal grid, and two-way diagonal grid. There are four types of grids and three-way grids. The second type is composed of quadrangular pyramid units, including square pyramid grids in the forward position, evacuated quadrangular pyramid grids in the forward position, square pyramid grids in the oblique position, checkerboard-shaped quadrangular pyramid grids and Five forms of star-shaped quadrilateral pyramid grid The third category is composed of triangular pyramid units, and has three forms: triangular pyramid grid, evacuated triangular pyramid grid and honeycomb triangular pyramid grid. According to the shell form, the shell grid structure mainly includes cylindrical shell grid, spherical shell grid and hyperbolic parabolic shell grid. According to the materials used, grid structures are divided into steel grids, reinforced concrete grids and combined grids composed of steel and reinforced concrete. Among them, steel grids are used more frequently. The internal stage force analysis grid structure is a high-order statically indeterminate structural system. When analyzing the plate grid, it is generally assumed that the nodes are hinged, and the external load is acted on the nodes according to the static equivalent principle. The calculation can be carried out according to the space truss displacement method, that is, the finite element method of the articulated rod system. Simplified calculation methods can also be used, such as the differential analysis method of cross-beam systems and the pseudo-plate method, to calculate internal forces and displacements. The nodes of single-layer shell grids are generally assumed to be rigidly connected and should be calculated according to the finite element method of rigidly connected rod systems. Double-layer shell grids can be calculated according to the finite element method of articulated rod systems. The pseudo-shell method can also be used to simplify calculations for single-layer and double-layer shell grids. Rod section design and node construction The rod section of the grid structure should be determined based on strength and stability calculations. In order to reduce the calculated length of the pressure rod and increase its stability, measures such as adding subdivision rods and support rods can be adopted. Stage points are built using the joints of plate-type grids and double-layer shell-type grids made of steel. There are three main forms: cross-plate nodes, welded hollow ball nodes and bolted ball nodes. The cross plate joint is suitable for the grid structure of the steel rods. The connection between the rods and the node plate is welded or high-strength bolted. Hollow ball joints and bolt ball joints are suitable for grid structures of steel pipe members. The nodes of the single-layer shell-type grid should be able to withstand the bending internal force. Generally, the steel consumption of the nodes accounts for ~ of the steel used in the entire steel grid structure. The construction and installation methods of the grid structure are divided into two categories. One is the overall jacking method, the overall lifting method and the overall hoisting method that are assembled on the ground. The other is the bulk assembly, strip and block assembly and high-altitude installation. Sliding in place assembly and other methods. Mr. Zhang Yuming, vice president of the Zhengzhou Federation of Industry and Commerce Etiquette and Celebration Industry Chamber of Commerce, president of the Jining City Federation of Industry and Commerce Etiquette and Celebration Industry Chamber of Commerce, and chairman of the company, wholeheartedly welcomes new and old customers to come and negotiate cooperation! Set up stage Telephone Website Address National Highway, Yanzhou City, Jining City, Zhengzhou Province Stage truss next to Wanglu Overpass (China Annual Exhibition Equipment Truss Factory, octagonal prism products continue to be optimistic about development) In addition to the points mentioned above, a good booth design must also consider the use of graphics and text. Graphics and text mainly refer to In terms of text descriptions, illustrations, photo backgrounds, etc., it plays the same important role as the exhibits. Especially in the booth design of some small exhibits, the importance of graphics and text is even more prominent. It conveys relevant information about the company's products to the audience. , and strive to leave a deep impression on the audience. In the specific design, the size and direction of the graphics and text should be determined according to the location of the booth and the flow direction of the audience. The graphics and text need to give people a "getting to the point" effect, rather than The audience is required to spend a certain amount of time and energy on setting up the stage to guess which company it is and what product it is. In order to provide humanized services in cross-arm exhibition venues, we must first analyze the types of exhibition activities. Different exhibition activities have very different service requirements for venues. For example, trade fairs are different from pure conferences, and pure conferences are different from large-scale festivals. Therefore, distinguishing the nature of the event can provide corresponding services in a targeted manner. Secondly, venue managers can analyze the participants of exhibition activities, divide them into different categories, analyze the behavioral characteristics of each category of participants, and provide targeted differentiated services to satisfy most participants. needs. Finally, humane services at venues require education and training for staff. Excellent service quality actually comes from the performance of the on-site staff at the venue. A warm smile and an intimate greeting will give people a warm feeling when setting up a stage.
