As shown in fig. 1 to 8, a prefabricated cavity 204 member for a space structure floor includes: the base 1 comprises a bottom plate 10 and a plurality of ribs 11 extending upwards along the bottom plate 10; the main body module 2 is arranged on the bottom plate 10 and comprises a first formwork 20, a second formwork 21, a third formwork 22 and a fourth formwork 23 which are arranged alternately in sequence; the first formwork 20, the second formwork 21, the third formwork 22 and the fourth formwork 23 are all arranged in a triangular prism shape and respectively comprise an upper bottom 201, a side wall 202 and a lower bottom 203 which are sequentially connected from top to bottom; the upper bottom 201, the side walls 202 and the lower bottom 203 enclose a cavity 204 with side openings; the side openings of the cavities 204 of the first formwork 20, the second formwork 21, the third formwork 22 and the fourth formwork 23 face the front side, the right side, the rear side and the left side of the main body module 2 respectively, and the side walls 202 of the four form a pouring channel 200 of the main body module 2; the pouring channel 200 is arranged in a cross shape and is positioned at the opposite angle of the main body module 2, and the reinforcement columns 11 penetrate through the pouring channel 200. Namely, the first formwork 20, the second formwork 21, the third formwork 22 and the fourth formwork 23 preferably enclose four mutually communicated pouring channels 200, so that the support strength of the spatial structure floor is maximized, and the overall structure strength is improved.

It should be explained that the first mold shell 20, the second mold shell 21, the third mold shell 22 and the fourth mold shell 23 have the same structure, that is, the first mold shell 20, the second mold shell 21, the third mold shell 22 and the fourth mold shell 23 are actually the same mold shell, and the positions thereof can be interchanged, thereby reducing the types of mold shells, reducing the number of molds used for molding the mold shells, and further reducing the manufacturing cost of the mold shells. Specifically, the shuttering is connected by an upper base 201, a side wall 202 and a lower base 203 to form a triangular prism shape. The upper bottom 201 is parallel to the lower bottom 203, and the upper bottom 201 and the lower bottom 203 are both arranged in a right triangle; the side walls 202 comprise a first side wall 202A and a second side wall 202B which are perpendicular to each other, the first side wall 202A is connected between a right-angle side of the upper bottom 201 and a right-angle side of the lower bottom 203, and the second side wall 202B is connected between the other right-angle side of the upper bottom 201 and the other right-angle side of the lower bottom 203.

After concrete is poured in the pouring channel 200, the tops of the first formwork 20, the second formwork 21, the third formwork 22 and the fourth formwork 23 are also poured, and the reinforcement columns 11 extend out, so that the top of the hollow floor is well connected with the bottom plate 10 at the bottom. A plurality of steel bars 12 are arranged in the bottom plate 10 side by side along the length direction and the width direction of the bottom plate, and the plurality of steel bars 12 can be understood as steel bar meshes or steel wire meshes or exposed bars or exposed nets.

In the practical use process, the prefabricated hollow member is formed by combining a base 1 and a first formwork 20, a second formwork 21, a third formwork 22 and a fourth formwork 23 which have the same structure, the first formwork 20, the second formwork 21, the third formwork 22 and the fourth formwork 23 are arranged at intervals and oppositely to form four pouring channels 200, reinforcing columns 11 on the base 1 penetrate through the four pouring channels 200, and after concrete is poured, main ribs or beams or walls of a cast-in-place structure can be formed.
