Detailed Description

The utility model is described in detail below with reference to the figures and specific embodiments.

A temporary stand structure of a combination and assembly type according to the present invention, as shown in the accompanying drawings, comprises a third member C, the third component C is an isosceles trapezoid structure, the left and right second components B respectively comprise a top plate 4 and a bottom plate which are arranged in parallel up and down along the horizontal direction at intervals, the length of the bottom plate 8 is less than that of the top plate 4, an outer steel plate 7 arranged along the vertical direction is fixed between the top plate 4 and the left side of the bottom plate, the top wall of an inner steel plate 5 arranged along the vertical direction is fixed on the bottom wall of the right side of the top plate 4, the length of the outer steel plate 7 is greater than that of the inner steel plate 5, the upper end of an inclined plate 6 is fixedly connected with the bottom of the inner wall of the inner steel plate 5, the lower end of the inclined plate is fixedly connected with the right end of a bottom plate 8, and a front wall plate and a rear wall plate are respectively plugged at the front and rear frames enclosed by the top plate 4, the bottom plate, the outer steel plate 7, the inner steel plate 5 and the inclined plate 6.
