Description

Building structure unit and basement exterior wall structure

The invention relates to a building structure unit and a basement exterior wall structure composed of a plurality of the building structure units.

Common basement wall structures include columns surrounding the basement and walls connecting between the columns. However, since there may be groundwater on the outside of the basement wall structure, and it is difficult to achieve a completely tight connection between the wall and the column in the conventional basement wall structure, there is often a problem of water seepage at the interface between the wall and the column.

Therefore, how to effectively solve the problem of water leakage of the basement exterior wall structure without greatly increasing the construction cost and construction complexity is what the industry is looking forward to.

The reason is that, in order to achieve the above purpose, an aspect of the present invention is related to a building structure unit, which includes a pillar, a first wall, a second wall and an additional structure. One end of the first wall is connected to a first side of the pillar. A first interface is defined between the end of the first wall and the first side surface of the pillar. One end of the second wall is connected to a second side of the pillar. A second interface is defined between the end of the second wall and the second side surface of the pillar. The added structure extends and connects along one side of the first wall, at least one first part of the pillar, and one side of the second wall. The added structure covers one side of the first interface and one side of the second interface.

Another aspect of the present invention relates to a basement exterior wall structure, which is a closed structure composed of a plurality of building structural units as described above.

The building structure unit provided by the present invention and the basement outer wall structure formed by it can effectively prevent the water leakage of the basement outer wall structure without affecting the appearance of the basement. In addition, the reinforced structure provided by the present invention can also increase the structural strength and stability between the walls and columns of the basement exterior wall structure.
