Abstract
Description
Technical Field
[0001] The utility model relates to the technical fields of basement waterproofing, balcony moisture-proofing and earth backfilling, in particular to a protective system under a residential cantilevered balcony. Background Art
[0002] With the acceleration of urbanization, people's living standards are constantly improving, and material living conditions are constantly increasing. To meet people's growing material needs, in residential projects, project designers and construction companies are constantly pursuing the utilization and development of underground space. In addition, to meet the demand for landscaping, a large amount of planting soil is backfilled on the basement roof to meet people's living and leisure needs.
[0003] During backfill construction, manual labor combined with compaction machinery is used to meet the backfill compaction requirements and reduce problems such as damage to the garden caused by subsequent settlement. The backfill beneath the cantilevered balcony slabs of residential buildings cannot be compacted using compaction machinery due to the height limit of the completed balcony slabs. It can only be filled loosely. Over time or after heavy rain, rainwater enters the backfill, often causing uneven sinking of the backfill, cracking the scuttle or sinking with it. This can cause cracks between the scuttle and the structure, and may cause water seepage from cracks in the basement roof. The water vapor in the cavity will cause moisture to return to the balcony structural slabs, causing erosion and damage to the building surface, seriously affecting the quality of subsequent use. Utility Model Content
[0004] In response to the deficiencies in the above-mentioned background technology, the present invention proposes a protective system under a residential cantilevered balcony, which solves the problems in the prior art of difficulty in backfilling the cavity under the cantilevered balcony and local collapse and settlement caused by long-term garden water use and rainwater erosion.
[0005] The technical solution of the present utility model is achieved as follows:
[0006] A protective system under a residential cantilevered balcony comprises a closed supporting structure arranged below a balcony structural plate, a backfill structure being provided on the side of the closed supporting structure facing the outdoors, and a waterproof and heat-insulating structure being constructed between the backfill structure and the closed supporting structure; the closed supporting structure comprises a masonry wall and a retaining wall, the masonry wall being arranged between the end of the balcony structural plate and the basement structure top plate and flush with the balcony structural plate, the masonry wall forming a closed space with the basement structure top plate, the balcony structural plate and the basement outer wall, the closed space being provided with at least one retaining wall, and the bottom of the balcony structural plate being paved with a moisture-proof layer. By constructing a moisture-proof layer under the balcony structural slab, the erosion resistance of the balcony structural slab is improved; by setting up a thermal insulation and moisture-proof structure, a good foundation waterproof function is laid to prevent the erosion of the balcony structural slab by water accumulated in the cavity under the balcony; by setting up a waterproof and thermal insulation structure, the anti-leakage capacity of the enclosed space under the balcony structural slab and the area above the basement structure top plate is strengthened; by setting up a closed support structure, a closed space is formed under the balcony structural slab, and by setting up a retaining wall, the anti-collapse and anti-subsidence effect is improved, and then by setting up a backfill structure, the soil around the balcony is consolidated to reduce the erosion of rainwater on the masonry wall, ensure the greening rate of the garden, and improve the survival rate of the garden.
[0007] Furthermore, the waterproof and thermal insulation structure includes a plaster layer, an insulation layer, and a masonry protective layer. The plaster layer is disposed on the outside of the masonry wall and extends to the top of the balcony structural slab. The plaster layer protects the masonry wall from adverse environmental factors. The insulation layer is disposed on the outside of the plaster layer and at the same height as the plaster layer, providing insulation for the enclosed space under the balcony structural slab. A waterproof layer and an additional waterproof layer are disposed between the plaster layer and the insulation layer. This double layer of protection enhances the waterproofing of the cavity. A masonry protective layer is disposed on the outside of the insulation layer to protect the enclosed space under the balcony structural slab.
[0008] Furthermore, a waterproof protective layer is laid on the top surface of the basement structure roof, one end of the waterproof protective layer extends to the outer wall of the basement and overlaps with the moisture-proof layer to form a first waterproof layer, thereby improving the moisture-proof and waterproof capabilities; a concrete protective layer is laid on the waterproof protective layer, and the concrete protective layer extends outward from the outer wall of the basement to the lower part of the backfill structure, thereby improving the waterproof protection of the bottom of the system.
[0009] Furthermore, the concrete protective layer is provided with a reserved groove outside the masonry wall and corresponding to the waterproof insulation structure, and the waterproof additional layer and the waterproof layer are overlapped with the waterproof protective layer at the reserved groove, thereby enhancing the waterproof ability of the waterproof insulation structure.
[0010] Furthermore, the joints between the moisture-proof layer and the waterproof protective layer are caulked with sealing grease to improve the sealing performance and enhance the waterproof performance.
[0011] Furthermore, a heat-insulating and moisture-proof structure is provided within the enclosed space and close to the basement's outer wall. The heat-insulating and moisture-proof structure comprises a protective layer and a brick wall protective layer. The protective layer is applied outside the first waterproof layer to improve waterproofness. A brick wall protective layer is stacked outside the protective layer to improve thermal insulation.
[0012] Furthermore, the retaining wall is located between the masonry wall and the brick wall protective layer, and the distance between two adjacent retaining walls is ≤1.5 meters, so as to resist the horizontal stress of the masonry wall caused by the lateral pressure of the earth.
[0013] Furthermore, the moisture-proof layer evenly covers the bottom surface of the balcony structural board and is folded down 5 cm along the outer wall of the basement, thereby improving the waterproof performance of the bottom of the balcony structural board.
[0014] Furthermore, drainage ditches and splashbacks are opened around the main body of the balcony. The drainage ditches are 600-1000mm away from the main structure of the building, and the splashback slope is not less than 3%, which reduces the infiltration of rainwater and timely diverts rainwater to the external network.
[0015] Furthermore, the backfill structure includes ash soil backfill and planting soil backfill. The ash soil backfill is close to the waterproof and thermal insulation structure, and the planting soil backfill extends outward with the ash soil backfill as the boundary. A 3:7 ash soil backfill is performed on the slope outside the waterproof and thermal insulation structure and limited to the boundary of the drainage ditch to strengthen the waterproof structure and improve the survival rate of the garden.
