Embodiment Construction

[0013] Embodiments of the present invention: the double supports of the arc-shaped large-space network frame of the present invention can be made according to the following method: the network frame support ball 6, stiff rib plate 5, and base plate 4 can be made by materials such as steel or iron; Drill 3 to 6 through holes on the two base plates 4 respectively, and weld the two base plates 4 on the two rib plates 5 respectively; weld the two rib plates 5 on the grid support ball 6, and make the The supporting surfaces 2 and 3 of the two base plates 4 are kept perpendicular to each other. Correspondingly, two supporting surfaces perpendicular to each other should also be made on the foundation short column 7 connected with the double support. During use, the two supporting surfaces 2 and 3 of the double support are respectively fixed on the two supporting surfaces of the foundation short column 7 by bolts, and then the arc-shaped large-space grid 9 is connected with the double...

Abstract

The invention discloses a method for treating a circular arc spacious net rack bearer and a double bearer thereof. The method for treating the circular arc spacious net rack bearer of the invention is as follows: the circular arc spacious net rack is used in the method, firstly a basic short column supporting the circular arc spacious net rack is provided with a horizontal plane and a vertical plane vertical to each other, and two net rack double bears, bearing surfaces of which are vertical to each other, are fixed on the horizontal plane and the vertical plane of the basic short column respectively, and the circular arc spacious net rack is connected with the double bearers, therefore, the horizontal force generated by the circular arc spacious net rack can be directly transferred to the basic short column, thereby the stability of the circular arc spacious net rack is improved. Compared with prior art, the double bearer used in the invention can make the circular arc spacious net rack generate tremendous horizontal force to be directly transferred to the basic short column, thereby avoiding the horizontal force supported by welding seams, greatly improving the stability of the circular arc spacious net rack structure and bring the safety guard for manufacturing and processing.

Description

technical field [0001] The invention relates to a processing method for a support of an arc-shaped large-space network frame and a double support thereof. Background technique [0002] Arc-shaped large-space grid structures are often used in production and processing. For example, the homogenization silo is about 230-320m in length, 42m in span, and 20m in radius, with a large arc-shaped space grid structure, and a steel platform with an elevation of 12.000 is suspended on the grid (see Figure 3). The self-weight of the steel platform and the grid produces a large horizontal force at the support of the grid. The usual method of grid support is to make the support into a single support. The method of single support is to weld a grid support stiffener under the grid support ball, and weld a bottom plate under the grid support stiffener. Bolt the bottom plate to the level of the foundation studs (as attached figure 2 ). In this way, the horizontal force generated by the gri...
