In addition, the plate surface of the top plate 13 is vertical to the plate surface of each side plate 11; the plate surface of the bottom plate 14 is perpendicular to the plate surface of each side plate 11.

Since the thickness of the web 12 is smaller than the width of the side plate 11 (obviously, the width direction of the side plate 11 is perpendicular to the plate surface of the web 12), the web 12 and each side plate 11 can be surrounded to form a web groove, and the web 12 is used as a groove bottom and each side plate 11 is used as a groove wall. Wherein, the number of the ventral troughs may be one or more, specifically:

Or, a belly connecting plate 151 which is in close contact with the web 12 and an edge connecting plate 152 which is in close contact with the corresponding edge plate 11 extend from the corresponding side edge of the sheet-like plate, and based on this structure, while the structural strength and rigidity of the top plate 13 and the bottom plate 14 are ensured, the weight of the top plate 13 and the bottom plate 14 can be effectively reduced, and the connecting operation (especially, the bolt connection) between the top plate 13/the bottom plate 14 and the base body 10 is facilitated; meanwhile, bracket structures are formed between the sheet-shaped plates and the belly connecting plates 151 and between the sheet-shaped plates and the edge connecting plates 152, so that the bearing capacity and the stress performance of the top plate 13 and the bottom plate 14 can be guaranteed.

For the solution that the top plate 13 and the bottom plate 14 are respectively embedded in the web groove, the top plate 13/the bottom plate 14 and the corresponding plate body are preferably fixedly connected by bolts, wherein, taking the top plate 13 as an example, the top plate 13 and the web 12 are preferably fixedly connected by a plurality of bolts, and the top plate 13 and each side plate 11 are fixedly connected by at least one bolt. In the above scheme that the top plate 13/the bottom plate 14 includes a plurality of sub-plates 15, taking the top plate 13 as an example, preferably, the bolts sequentially penetrate through one of the sub-plates 15, the web 12 and the other sub-plate 15 and are locked by nuts, so that the sub-plates 15 are connected into a whole to cooperatively bear force, and meanwhile, the bolt assembly operation is facilitated, and the connection reliability is ensured. When the top plate 13/the bottom plate 14 are block-shaped plates, two ends of the block-shaped plates are preferably closed ends, and two ends of the block-shaped plates and the corresponding side edge plates 11 can be connected by self-tapping screws, or operation windows are formed in the block-shaped plates so as to facilitate nut screwing operation; when the top plate 13/the bottom plate 14 are formed of sheet-like plates, sufficient space for the bolts to be fitted between the edge connecting plates 152 and the corresponding side plates 11 is provided.

It can be understood that, based on the above structural design, the top plate 13 and the bottom plate 14 can adopt the same structure and can be replaced with each other, thus facilitating standardized production and standardized construction, eliminating the need for classifying prefabrication, transportation, storage and installation of the top plate 13 and the bottom plate 14, and significantly improving construction convenience and efficiency.

In an alternative embodiment, a rest beam is installed in the web groove for resting the cross beam and can act as a transverse stiffening rib, further improving the structural strength and the stress performance of the building element 1; the joist can adopt the same structural components and the same installation mode (only bolt installation holes are correspondingly arranged on the base body 10) as the top plate 13, and the installation position of the joist is positioned below the top plate 13. It will be appreciated that the joist may also be of the same standard construction as the top and

bottom panels

13, 14, which may further facilitate the standardized production and standardized construction of the building element 1 described above.

Further preferably, as shown in fig. 6, a vertical stiffener 16 is further disposed on the web 12, and a length direction of the vertical stiffener 16 is parallel to a length direction of the sideboard 11.

For the scheme that the split prefabricated building component 1 is a prefabricated column component, the vertical stiffening rib plates 16 are not required to be arranged.

The weight of the building element 1 can be reduced by the existence of the abdominal groove, and in a preferred scheme, the abdominal groove can also be used as a filling space of a heat insulation material, namely, the abdominal groove is filled with a heat insulation layer, so that the heat insulation performance of the building element 1 and a related building can be effectively improved. The heat-insulating layer can be made of heat-insulating materials such as heat-insulating cotton, foamed concrete or building blocks; for example, if the rock wool block is adopted, the rock wool block is adhered to the surface of the web 12; when the foamed concrete is used, it may be consolidated in the abdominal groove by means of shotcrete or the like. The heat-insulating layer can be simultaneously applied when the components are prefabricated, and can also be applied on the construction site.

The building component 1 is further optimized, and the connecting part is used for being connected with an adjacent component, so that the assembly construction is facilitated; in one embodiment, as shown in fig. 1 to 13, the connecting portion includes bolt mounting holes opened on the corresponding plate body. The bolt assembly holes are preferably communicated with the abdominal grooves, after two adjacent prefabricated parts are aligned, the bolts penetrate through the bolt assembly holes of the two prefabricated parts and then are locked through the nuts, so that the two prefabricated parts can be assembled and fixedly connected, the stability and the reliability of the assembly structure are high, and the bolt assembly holes can be bolt through holes or threaded holes; it can be seen that the bolt assembly is allowed by the web 12 with a small thickness, and the assembly efficiency and effect can be improved because of the sufficient operation space.
