The specific embodiment

As shown in Figure 1, the utility model arena stage comprises the girder 23 that is arranged on the middle part, girder 23 is by

left pillar

21 and 22 supportings of right pillar, as shown in Figure 2, the left end of girder 23 rides on the left pillar 21, and left pillar 21 and girder 23 corresponding positions are provided with pin hole, by insert latch 24a in pin hole, make to fix between the two and the changing of the relative positions can not take place, right pillar 22 and girder 23 fix in the same way.

Again as shown in Figure 1, be symmetrical arranged two pack modules along girder 23, first pack module comprises 10 module 1-10 that be arranged in parallel, the 2nd pack module also comprises 10 module 11-20 that be arranged in parallel, module 11 to 20 and module 1 are symmetrical arranged one by one to 10, and two pack modules constitute two semi-circular portion of an arena stage respectively.

Wherein, an end of each module is by girder 23 supporting, and the other end is by 31 supportings of two pillars, and two adjacent blocks can a shared pillar, and for example, shown in Fig. 1,3, an end of module 5 is supported by girder, and the other end is by

pillar

35,36 supportings; One end of module 6 is supported by girder, and the other end is by

pillar

36,37 supportings, and pillar 36 is

module

5 and 6 shared pillars, and pillar 37 is module 6 and 7 shared pillars, and the support pattern of other module similarly.
