Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blocking the post-cast strip of the basement outer wall, in particular to a waterproof structure for blocking the post-cast strip of the basement in advance. Background Art
[0002] The traditional additional protective layer structure on the outside of the post-cast strip of the basement exterior wall is generally sealed by brickwork, prefabricated panels, etc., which eventually forms a thick sealing layer protruding from the exterior wall of the basement. When waterproofing the sealing layer, the protruding position forms an unfavorable structure of a inner corner and a outer corner, making it difficult to handle the waterproofing of this part, which is very likely to cause quality risks of leakage after the building is delivered for use.
[0003] In the prior art, steel plates are used for blocking, which can form a thinner blocking layer and facilitate the construction of the waterproof layer. However, the steel plates are heavy and the construction is inconvenient. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a basement post-cast strip advanced plugging waterproof structure with simple construction, thin plugging layer and good plugging effect.
[0005] In order to achieve the above purpose, the utility model provides a waterproof structure for pre-sealing the post-cast zone of the basement, and the technical scheme is as follows:
[0006] The waterproof structure for advanced plugging of the post-cast strip of the basement comprises: a plugging layer, the width of the plugging layer is greater than the width of the post-cast strip; the plugging layer comprises plugging plates spliced from top to bottom; the vertical sides of the plugging plates are fixed to the concrete walls on both sides of the post-cast strip by expansion bolts; the plugging plates comprise inner supporting plates, outer supporting plates and ribs arranged from top to bottom between the inner supporting plates and the outer supporting plates; the inner supporting plates, outer supporting plates and ribs are FRP (glass fiber reinforced plastic) plates; a leveling layer, the leveling layer is arranged on the outer side of the plugging layer and the outer side of the concrete walls on both sides of the plugging layer; a waterproof layer, the waterproof layer is arranged on the outer side of the leveling layer.
[0007] First of all, compared with steel plates, the use of FRP plates as the main material of the waterproof structure of the basement post-casting zone has the following advantages: The density of FRP plates is much lower than that of steel plates, making FRP plates lighter during transportation and installation. FRP plates have excellent chemical corrosion resistance and are very suitable for use in underground buried environments without the need for additional anti-corrosion treatment. FRP plates have good toughness and impact resistance, can better resist foundation pit deformation and external forces, and improve the durability of the overall structure. FRP plates have good processability and can be directly cut into suitable sizes and assembled by bonding or mechanical connection. The construction operation is relatively simple. The raw materials and production costs of FRP plates are low, and they have certain economic advantages.
[0008] Secondly, the blocking plate includes an inner support plate, an outer support plate, and ribs arranged from top to bottom between the inner support plate and the outer support plate, wherein the inner and outer layers of the support plates can form an integral load-bearing frame, thereby improving the overall rigidity and deformation resistance; the ribs are arranged at intervals along the longitudinal direction, which play a reinforcing role and can effectively transmit and disperse the pressure in the upper and lower directions; the synergistic effect of the inner and outer support plates and the ribs forms an overall structure with high rigidity and strong bearing capacity, which can reliably resist various loads at the edge of the foundation pit.
[0009] It can be seen that the waterproof structure of the basement post-cast strip advance plugging of the utility model has a simple structure and is easy to construct. The comprehensive performance of the plugging board composited with FRP boards is relatively outstanding, and it can form a plugging layer with high strength and good stability. In practical applications, it can better meet the various performance requirements of the basement post-cast strip construction project.
[0010] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast zone of the basement: the plugging layer also includes elastic strips filled between the ribs of the upper and lower plugging plates. As a result, the elastic strips can play the following roles: enhance the overall rigidity and bearing capacity of the entire plugging plate, improve its anti-deformation performance, and improve the stability and reliability of the overall structure; play a certain buffering role, absorb and disperse the local stress concentration caused by external loads, and enhance the overall impact resistance; the filling of the elastic strips can reduce the gap between the inner and outer support plates, and improve the waterproof compactness of the entire plugging layer; the elastic strips have a certain deformation capacity, and can provide buffering when the temperature change causes structural deformation, reducing the harm of temperature stress.
[0011] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast strip of the basement: the width of the outer support plate is greater than the width of the inner support plate, the width of the inner support plate is adapted to the distance between the concrete walls on both sides of the post-cast strip, and the vertical sides of the outer support plate are fixed to the concrete walls on both sides of the post-cast strip by expansion bolts. As a result, the width of the outer support plate is greater than that of the inner support plate, forming a "convex" structure, which can make the inner support plate smoothly embedded in the space between the walls while making the two sides of the outer support plate better fit with the concrete walls on both sides of the post-cast strip, making the overall structure more stable and better able to resist various forces at the edge of the foundation pit.
[0012] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast strip of the basement: the vertical distance of the two sides of the outer support plate exceeds the inner support plate by 150-250mm. Thus, the distance is appropriate, so that the two sides of the outer support plate can better fit with the post-cast strip wall, and the connection strength between the entire plugging layer and the concrete wall is enhanced.
[0013] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast strip of the basement: the vertical sides of the outer support plate are fixed to the concrete walls on both sides of the post-cast strip by two rows of expansion bolts. Thus, the overall stability of the entire plugging waterproof structure is improved, the risk of deformation is reduced, and its long-term reliable use is ensured.
[0014] As a further improvement of the above-mentioned basement post-cast zone advance plugging waterproof structure: the expansion bolts are M8 expansion bolts.
[0015] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast zone of the basement: the thickness of the FRP plate is 2-4 mm; the spacing between the inner support plate and the outer support plate is 1-2.5 cm; the spacing between the ribs is 1-2.5 cm. In this way, the load-bearing requirements can be met without being too heavy, which is convenient for construction operation.
[0016] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast zone of the basement: the waterproof layer is made of waterproof rolls, and the width of the joint is 300-500mm; the leveling layer is a cement mortar layer, thereby ensuring the waterproof performance and facilitating the construction operation.
[0017] As a further improvement of the above-mentioned waterproof structure for advanced plugging of the post-cast zone of the basement: it also includes a protective layer arranged outside the waterproof layer, and the protective layer is a polystyrene board or a foam board. Thus, the protective layer can take into account both waterproofing and heat preservation requirements, can effectively protect the waterproof layer from damage by various external factors, and greatly extend the service life of the waterproof layer.
