Abstract
Description
Technical Field
[0001] The utility model relates to a post-cast strip structure of a basement floor. Background Art
[0002] The current post-cast strip of the underground garage floor is to simply disconnect the basement floor, add a common plain concrete cushion layer, and set a waterproof layer and its protective layer on top. Although this method can achieve the effect of the post-cast strip, it is easy to cause underground backflow, damage to the waterproof layer, poor post-casting quality, poor ground flatness, and even easy water seepage in the post-cast strip in the face of complex construction environments. Utility Model Content
[0003] The utility model aims to provide a basement floor post-cast strip structure with improved construction quality and waterproof performance.
[0004] The purpose of the utility model is achieved in this way:
[0005] A post-cast strip structure of a basement floor, comprising a basement floor, a concrete cushion layer, a reinforced concrete pre-construction floor with a thickness of 200 mm and a split joint in the middle, and expansive concrete, wherein the basement floor is provided with the concrete cushion layer, a single-sided polymer-modified asphalt waterproofing membrane with a thickness of 1.5 mm, and a pre-laid plastic waterproofing membrane P with a thickness of 1.2 mm in sequence from bottom to top;
[0006] The concrete cushion layer is provided with a post-casting zone, and the post-casting zone is provided with a waterproof additional layer;
[0007] The reinforced concrete first construction bottom plate is arranged on the range of the post-casting zone and above the waterproof additional layer;
[0008] The concrete cushion layer is located on both sides of the reinforced concrete first construction bottom plate, and reinforced concrete layers are arranged, and the reinforced concrete layers are located above the pre-laid plastic waterproofing membrane P type;
[0009] The expansive concrete is arranged above the concrete first construction base plate;
[0010] The split seam positions are provided with waterproof caulking materials;
[0011] The expansive concrete and reinforced concrete first construction base plates are both provided with a steel plate waterstop with a thickness of 3 mm.
[0012] Enhanced base slab waterproofing performance: A double-layer waterproofing structure combining 1.2mm thick pre-laid plastic waterproofing membrane P type and 1.5mm thick single-sided polymer modified asphalt waterproofing membrane (tired type) is used to improve the overall performance of the waterproof layer, effectively prevent groundwater infiltration, and ensure that the base slab waterproofing layer is not easily damaged during construction and use.
[0013] The construction environment is clean and tidy: first construct a 200mm thick base plate and set joints to ensure the cleanliness of the post-pouring zone, avoid the impact of the complex environment in the later stage on the base plate construction, and facilitate the smooth progress of the later construction.
[0014] Improve construction quality: set up a waterproof additional layer within the post-pouring zone, and use waterproof caulking materials at the joint positions to ensure the overall high construction quality of the base plate, good ground flatness, and reduce construction errors and quality problems.
[0015] Reliable waterproofing measures: Use a 3mm thick steel waterstop to water-stop the expansive concrete and the first constructed base plate, further enhancing the waterproofing effect of the post-cast strip and ensuring the waterproofing performance of the underground garage during use.
[0016] Convenience of construction: The method of constructing part of the base plate first and setting the joints makes the construction of the post-casting strip more convenient and is not affected by the complexity of the later construction environment. It simplifies the construction process and improves construction efficiency.
[0017] Easy post-maintenance: Complete waterproof layer construction and reliable water-stopping measures reduce the difficulty and frequency of post-maintenance, reduce maintenance costs, and extend the service life of the basement floor.
[0018] The beneficial effects of the utility model are as follows:
[0019] The utility model, by optimizing the structure and construction method of the post-cast strip of the basement floor, not only improves the waterproof effect and construction quality, but also significantly improves the construction environment and convenience, and has significant practical value and promotion prospects.
