Description

A basement structure with waterproof structure

technical field

The utility model relates to a basement structure, in particular to a basement structure with a waterproof structure.

Background technique

Under the conventional design, the basement of a building should be a complete structure connected by construction joints between the roof, side walls, and bottom plates, and the waterproof layer of the roof, side walls, and bottom plates wraps it into a closed system. However, under certain conditions, such as the phased construction of the basement, when the basement of the first phase is constructed, the basement of the second phase does not have the conditions for excavation, and a reinforced concrete layer needs to be added between the first and second phases as a side wall retaining soil. In this case, the basement roof and floor are reserved for the second phase of construction by way of post-casting strips, but the newly added side walls cannot be connected with the roof and floor with construction joints, and the construction work area is insufficient. The conventionally designed flexible waterproof layer cannot be constructed on the newly added side wall.

Contents of the invention

The purpose of this utility model is to provide a basement structure with a waterproof structure under specific conditions. In the utility model, the specific condition is that when the basement of the first phase is constructed, the basement of the second phase has excavation conditions. The basement structure with a waterproof structure meets the phased construction and waterproof requirements of the basement, and meets the construction requirements under the condition of lack of a construction work surface.

In order to achieve the above object, a basement structure with a waterproof structure includes a basement main structure roof and a basement main structure bottom plate, a roof waterproof layer is provided on the basement roof, and a basement waterproof layer is provided on the basement main structure bottom plate; the basement main structure roof and the basement There is a side wall structural plate between the bottom plates of the main structure. The side wall structural plate is located between the first-phase basement and the second-phase basement. The waterproof layer of the side wall structural plate is a cement-based permeable crystalline waterproof coating layer. The cement-based The permeable crystalline waterproof coating layer overlaps with the waterproof layer of the top plate and the waterproof layer of the bottom plate.

Since the side wall structural plate is a newly added structure that cannot be constructed at the same time in the first and second phases, it cannot be constructed according to the construction joint technology. The waterproof layers are overlapped with each other, and the waterproof structure is strengthened at the junction of the structures to meet the requirements of daily use and facilitate construction, so as to solve the problem of insufficient construction work surface.

Further, structural joints are formed between the roof of the main structure of the basement and the structural plates of the side walls, structural joints are formed between the bottom plate of the main structure of the basement and the structural plates of the side walls, and cement-based permeable crystalline seals are sealed at the structural joints layer. This structure further improves the waterproof performance and further solves the problem of insufficient construction work surface.

Further, the top second-stage structural reinforcement is reserved at the end of the main structure roof of the basement close to the second-phase basement, and the second-stage structural reinforcement of the basement is reserved at the end of the main structure bottom plate of the basement close to the second-phase basement. This structure can guarantee the strength of the basement construction in the second phase.

Further, a top protective concrete layer is poured outside the second-stage structural steel bars at the top, and a bottom protective concrete layer is poured outside the second-stage structural steel bars at the bottom. It can well protect the top secondary structural reinforcement and the bottom secondary structural reinforcement.

Further, the side wall structural slab is a reinforced concrete slab.

detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the basement structure with waterproof structure includes the basement main structure top plate 1 and the basement main structure bottom plate 2, the basement roof 1 has a roof waterproof layer, and the basement main structure bottom plate 2 has a bottom plate waterproof layer.

As shown in Figure 2, the top second-stage structural reinforcement 3 is reserved at the end of the main structure roof 1 of the basement close to the second-phase basement, and a top protective concrete layer 4 is poured outside the top second-stage structural reinforcement 3. At the end of the basement main structure floor 2 close to the second-stage basement, a second-stage structural steel bar 5 is reserved, and a bottom protective concrete layer 6 is poured outside the second-stage structural steel bar 5 at the bottom. This structure has a connection foundation during the construction of the second phase of the basement, which can ensure the strength of the second phase of the basement construction, and can well protect the top second phase structural steel bars 3 and the bottom second phase structural steel bars 5 .

A side wall structural plate 7 is provided between the basement main structure top plate 1 and the basement main structure bottom plate 2. The side wall structural plate 7 is located between the first-phase basement and the second-phase basement, and the side wall structural plate 7 is a reinforced concrete plate . A structural seam is formed between the basement main structure top plate 1 and the side wall structural plate 7, and a structural joint is formed between the basement main structure bottom plate 2 and the side wall structural plate 7; the side wall structural plate 7 has a waterproof layer, and the side wall structure The waterproof layer of the board is a cement-based permeable crystalline waterproof coating layer. The cement-based permeable crystalline waterproof coating layer is overlapped with the roof waterproof layer and the bottom plate waterproof layer, and a cement-based permeable crystalline sealing layer is sealed at the structural joint position 8 .

The above-mentioned structure is suitable for phased construction of the basement. When the basement of the first phase is constructed, the basement of the second phase does not have the conditions for excavation.

Due to the lack of a construction work surface on the outside of the side wall structural plate 7, its waterproof layer adopts a cement-based permeable crystalline waterproof coating layer. Effectively overlap and overlap, and seal the cement-based permeable crystalline sealing layer 8 at the structural joints, so that the structure of the entire building is stable and waterproof, thereby solving the problem of insufficient construction work surfaces.
