The fixing member 8 in this embodiment supports the prefabricated tire membranes, specifically, supports the first prefabricated composite slab 1 and the second prefabricated composite slab 2, so that the first prefabricated composite slab 1 and the second prefabricated composite slab 2 can be firmly erected at the correct positions during and after the assembly process.
In this embodiment, at least one third embedded nut 9 matched with the fixing bolt 82 is disposed on the lower portion of the outer side surface of the first prefabricated composite slab 1.
In this embodiment, at least one fourth embedded nut 12 having the same specification as the third embedded nut 9 is disposed on the lower portion of the outer side surface of the second prefabricated composite slab 2.
One surface of the second corner brace 81 is fixed into the third embedded nut 9 or the fourth embedded nut 12 through the fixing bolt 82, and the other surface is fixed on the ground through the fixing bolt 82, so that the prefabricated tire membrane is fixed.
It should be noted that a layer of cement mortar setting slurry is laid in advance on the ground where the bearing platform is to be applied, and the prefabricated tire membranes are assembled on the cement mortar setting slurry. In the process, the fixing member 8 plays a role in supporting the first prefabricated composite slab 1 and the second prefabricated composite slab 2, that is, one side of the fixing bolt 82 penetrating through one side of the second corner connector 81 is fixed in the third embedded nut 9 or the fourth embedded nut 12 of the first prefabricated composite slab 1 or the second prefabricated composite slab 2, and the other side of the fixing bolt 82 penetrating through the other side of the second corner connector 81 is fixed on the ground after cement mortar is solidified. And after the prefabricated tire membranes are installed, concrete is poured, and the fixing piece 8 is detached after the concrete of the bearing platform is finished, so that the fixing piece 8 can be repeatedly used, and the cost of accessories is saved.
In the technical scheme, 2-5 fixing pieces 8 are arranged at the fixing position of each first prefabricated composite slab 1 and the ground; and 2-5 fixing pieces 8 are arranged at the fixing positions of the second prefabricated composite slab 2 and the ground.

In this embodiment, the chamfer 10 is provided on the edge of the inner side surface where the first prefabricated laminated slab 1 and the second prefabricated laminated slab 2 are spliced together.
Because there is the dislocation condition when first prefabricated superimposed sheet 1 splices with 2 concatenation of second prefabricated superimposed sheets, these dislocation can lead to the concatenation of first prefabricated superimposed sheet 1 and second prefabricated superimposed sheet 2 not tight, can produce the hourglass thick liquid phenomenon at the concreting in-process. And the edge of the medial surface that first prefabricated superimposed sheet 1 or the prefabricated superimposed sheet 2 of second spliced mutually sets up chamfer 10, can make the concatenation department of first prefabricated superimposed sheet 1 or the prefabricated superimposed sheet 2 of second form a concatenation seam 11 (as shown in fig. 1), and after first prefabricated superimposed sheet 1 or the prefabricated superimposed sheet 2 of second spliced mutually again with cement mortar to splice seam 11 and trowel, the problem that produces when concreting because of the concatenation of first prefabricated superimposed sheet 1 and the prefabricated superimposed sheet 2 of second is not tight can be solved in the setting of chamfer 10 and leak the thick liquid.
The specific assembling sequence of the prefabricated tire membranes and the manufacturing process of the bearing platform in the embodiment are as follows:
s001, paving a layer of cement mortar on the ground where the bearing platform is required to be arranged, and installing a fixing piece 8 after the cement mortar is solidified;
