As can be seen from fig. 1, the building bottom plate comprises a bearing surface, lapping parts which are oppositely arranged on two sides of the bearing surface, a strengthening wave crest is arranged between the lapping parts, the lapping parts on two sides of the bearing surface are that the bearing surface extends upwards and is bent downwards reversely to form a convex rib I1, the convex rib I1 is bent upwards to form an extending surface after extending horizontally, and the extending surfaces of the two lapping parts are bent towards the same direction again to form a combined surface. The shape of the joint surfaces of the lap parts at the two sides of the bearing surface is the same, but the sizes of the joint surfaces are different, the lap parts of the adjacent building bottom plates can be connected through the bending lap joint buckling force of the joint surfaces with different sizes, and after the lap parts of the two adjacent building bottom plates are connected through buckling lap joint, a groove 3 with a chute 2 structure formed by combining the two convex edges I1 is formed at the connecting position. The inner sides of two sides of each building bottom plate, which are close to the convex edges I1, are provided with a groove 3 which is parallel to the convex edges I1 so as to fix other suspension components.

Fig. 2 to 6 are schematic structural views of different angles of the support in a preferred embodiment of the invention. Fig. 2 is a front view, fig. 3 is a side view, fig. 4 is a top view, fig. 5 is a bottom view, and fig. 6 is a schematic perspective view. As can be seen from fig. 2 to 6, the support is composed of two pallets 41 with the same size and specification, a riser 42 with an overall trapezoidal structure, and two assembly members 5 at the bottom of the pallet 41. The two sides of the upper surface of the supporting plate 41 are provided with ribs II43 with the same size and specification. The support can be made of different parts which are fixedly connected, and can also be integrally formed by casting. The same two side surfaces of the support plate 41 are oppositely arranged, and the two support plates 41 are connected into a whole by the convex ribs II43 which are vertical to the corresponding side surfaces on the two sides of the upper surface of the support plate 41. Meanwhile, between the two ribs II43, two ends of the bottom edge of the vertical plate 42 are respectively fixedly connected with the upper surface part of the supporting plate 41. The plane of the supporting plate 41 is perpendicular to the plane of the vertical plate 42. The retainer plate 41 is provided with a screw hole 46 penetrating the circular table of the attachment 5 and penetrating into the retainer plate 41. As a result, the riser 42 can likewise take up forces on the pallet 41 when the fitting 5 and the pallet 41 are pulled. In order to reduce the weight of the vertical plate 42, a hollow structure 421 penetrating the plate body is provided on the vertical plate 42. Meanwhile, the outer side of the supporting plate 41, which is not connected with the vertical plate 42, is also provided with a through hole for a T-shaped screw rod and the like to pass through so as to fixedly connect the support with the building bottom plate. The assembly part 5 is a combination of a circular truncated cone and a bent plate with an L-shaped section. The side surface of the long-edge free end of the L-shaped cross section of the bent plate is fixedly connected with the side surface of the circular truncated cone, and the corner of the L-shaped cross section of the bent plate is of a fillet structure.

The corresponding side surfaces of the two support plates 41, the bottoms of the vertical plates 42 and the bottoms of the convex ribs II43 at the upper parts of the corresponding spaces form a limiting groove 44, and the span of the limiting groove 44, namely the distance between the corresponding side surfaces of the two support plates 41 is not less than the width of the upper flange of the used I-beam, so that the upper surface of the I-beam is just embedded into the limiting groove 44. Therefore, the supporting plates 41 extending from the two sides of the upper flange of the I-beam expand the supporting area of the upper flange of the I-beam and are crossed with the I-beam, and the supporting of the building bottom plate is facilitated. Meanwhile, the vertical plates 42 connected with the supporting plate 41 can also share the pressure on the I-beam and the supporting plate 41.

Meanwhile, the invention also provides a mounting assembly for mounting the I-beam by using the support. The mounting assembly includes at least an upper layer connector and a lower layer connector. Wherein, fig. 7 is a front view structure diagram of the upper layer connecting piece. Fig. 8 is a schematic structural view of the lower layer connecting piece. As can be seen from fig. 7, the upper layer connecting member is composed of a support 4, two fixing members 6, two fastening bolts 7, and two T-bolts (not shown). Wherein, the support 4 is fixedly connected with the fixing piece 6 into a whole through the threaded hole 46 and the fastening bolt 7. The T-shaped screw rod fixes the support on the building bottom plate through the through hole.

The fixing member of the upper connecting member is different from that of the lower connecting member (fig. 7 and 8). The whole section of the upper fixing piece 61 of the upper connecting piece is of an inverted trapezoidal structure without an upper edge, and a through hole or a threaded hole for penetrating and connecting the fastening bolt 7 is formed in the bottom surface. One side is connected with the L-shaped round corner of the bent plate through a connecting cylinder, and the other side is provided with a supporting surface for supporting the bottom of the parallel surface on the I-shaped beam 9. The difference of lower floor's connecting piece and upper strata connecting piece lies in: on one hand, the length of the fastening bolt 7 is longer because the bottom surface of the lower flange of the I-beam needs to be supported; on the other hand, only one fixing piece 6 is arranged, and the fixing piece 6 is of a channel structure with a through hole at the top and no bottom at the right side. Two ends of the fixing member 6 are connected to the two fastening bolts 7, and the other ends of the two fastening bolts 7 are connected to the threaded holes 46 of the two support plates 41, respectively. Thus, the lower fixing member 62 forms a support structure with the two fastening screws 7 so as to support the bottom surface of the lower parallel surface of the i-beam. The lower surface of the lower fixture 62 is provided with holes or slots for bolting so that the lower fixture 62 itself serves as a foundation for attaching other suspension members.

Fig. 9 is a mounting shaft view of a mounting assembly in a preferred embodiment of the invention (T-screw omitted). Fig. 10 is a side view of the structure of fig. 9. Fig. 11 is a schematic structural view of a lower-layer connecting member of a mounting assembly in a preferred embodiment of the invention. As can be seen from fig. 9 to 11, the mounting assembly comprises a total of 2 lower level connectors and 5 upper level connectors. This embodiment also includes 7 downwardly opening building floors 8 and an i-beam 9. Wherein, the top of the T-shaped screw 10 is connected with the chute 2 and fixed by a screw cap at the bottom of the through hole of the support 4. Downward slope-shaped protrusions are arranged on two sides of the T-shaped screw 10 to prevent the T-shaped bolt 10 from being fastened when the nut is rotated. Wherein, the riser 42, the recess 3 and the bead II43 cooperation of building bottom plate can prevent that when the fastening installation, support 4 uses fastening bolt to take place to rotate as the center, influences the installation. Meanwhile, when the limiting groove 44 is bridged on the I-beam, the vertical plate 42 of the connecting supporting plate 41 can provide stress with enough strength. In this kind of structure, the installation that hangs the piece is an assembly process, only need through the cooperation between each part structural feature connect can, need not to puncture and punch, perhaps welding operation to make whole installation more swift convenient, efficiency is higher, the security is also higher, and the energy consumption then is lower.
