Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a steel column roof waterproofing structure and building. Background Technology

[0002] In prefabricated buildings, it is common to see main structures extending beyond the roof, such as roof-mounted structural layers, roof-mounted machine rooms, and roof-mounted stairwells. In these roof-mounted structures, steel columns penetrate the roof structure. Current technology typically does not provide separate treatment at the junction of the steel column and the concrete roof, or simply applies a waterproof coating after construction. However, due to the temperature deformation of the steel column and the shrinkage and creep of the roof concrete, the steel column deforms more significantly with temperature, while the concrete undergoes less volume change. This inconsistent deformation can easily lead to cracks at the junction of the steel column and the concrete roof, causing leaks and posing potential quality risks. Utility Model Content

[0003] In view of this, the present invention provides a steel column roof waterproofing structure and building to solve the problem of leakage at the junction of steel column and concrete roof.

[0004] In a first aspect, this utility model provides a steel column roof waterproofing structure, comprising: a roof structure layer; a steel column penetrating the roof structure layer along its thickness direction; a waterstop plate, which is annular and is fixedly connected to the steel column, the waterstop plate being located within the roof structure layer; and a waterproof coating disposed on the outer side of the roof structure layer, the waterproof coating being applied to the joint between the steel column and the roof structure layer and being disposed around the steel column.

[0005] Beneficial effects: By connecting a ring-shaped waterstop plate to the outer surface of the steel column, extending the waterstop plate in a direction perpendicular to the center line of the steel column and away from the steel column, the leakage path is lengthened. Furthermore, the waterstop plate is located within the roof structural layer, not affecting the building's appearance, and the roof structural layer provides protection for the waterstop plate, preventing damage and increasing structural reliability. Simultaneously, by adding a waterproof coating at the joint between the roof structural layer and the steel column as a waterproofing and leak-stopping material, the waterproof coating seals any minor cracks, forming an extra layer of protection. The combination of the waterproof coating and the waterstop plate increases the difficulty of leakage, preventing leakage between the steel column and the roof structural layer, thus avoiding safety hazards caused by leakage. Moreover, the ring-shaped waterstop plate has a simple structure and can be directly assembled with the steel column, facilitating assembly and modularization, making construction convenient and conducive to industrial production and promotion.

[0006] In one optional embodiment, the steel column roof waterproofing structure further includes: mortar-covered foot, which is located at the corner formed by the intersection of the outer surface of the roof structure layer and the outer periphery of the steel column, and the mortar-covered foot covers the waterproofing coating.

[0007] Beneficial effects: By setting a mortar rim at the intersection of the outer surface of the roof structure layer and the outer perimeter of the steel column, corrosion of the steel column base is prevented, increasing structural durability and aligning with the concepts of green building and green development. Furthermore, by covering the anti-seepage coating with the mortar rim, the protective effect of the anti-seepage coating is enhanced. Thus, the combination of the mortar rim and the anti-seepage coating further strengthens the anti-seepage effect at the junction of the roof structure layer and the steel column, eliminating the safety hazards caused by leakage and corrosion of the steel column at the junction of the steel column and the roof structure layer.

[0008] In one optional embodiment, the steel column roof waterproofing structure further includes: a sealant applied at the junction of the mortar base and the steel column.

[0009] Beneficial effects: By applying sealant at the junction of the mortar base and the steel column, cracks are prevented between the mortar base and the steel column, further improving the water-stopping and seepage prevention effect.

[0010] In one alternative embodiment, the mortar base has a top surface facing away from the roof structure layer, the top surface being inclined relative to the roof structure layer, and the side of the top surface away from the steel column being lower than the side of the top surface close to the steel column, and the sealant is applied at the junction of the top surface and the steel column.

[0011] Beneficial effects: By setting the top surface of the mortar base at an angle relative to the roof structure layer, i.e., the top of the mortar base is a slope, water can flow smoothly down the slope, which can prevent water from accumulating on the top of the mortar base, thereby reducing the soaking of the sealant, extending the service life of the sealant, and further improving the water-stopping and seepage prevention effect.

[0012] In one alternative embodiment, the sealant is an elastic, weather-resistant, and waterproof material.

[0013] Beneficial effects: By using an elastic, weather-resistant, and waterproof sealant, the sealant possesses excellent anti-aging and waterproof properties. Furthermore, when the steel column and roof structure deform, and the deformation of the steel column and concrete is inconsistent, the elastic sealant can deform accordingly, promptly filling the cracks at the joint between the steel column and the roof structure. This ensures that the entire steel column-to-roof waterproof structure is free of cracks and gaps, achieving a water-stopping and seepage-proof effect.

[0014] In one optional embodiment, the steel column roof waterproofing structure further includes a structural beam disposed on the side of the roof structural layer opposite to the waterproofing coating.

[0015] Beneficial effects: The structural beams are connected to the steel columns to form a steel structural frame, which plays a load-bearing role and supports the roof structural layer. By setting up structural beams to support the roof structural layer, the reliability of the main structure of the building is ensured.

[0016] In one alternative embodiment, the waterstop is a steel plate.

[0017] Beneficial effects: Steel plate structures have high strength and reliability, and the materials are readily available and have low cost.

[0018] In one alternative embodiment, the waterstop is welded to the steel column.

[0019] Beneficial effects: By welding the waterstop to the steel column, a stable connection between the waterstop and the steel column can be ensured. The welding has high reliability and good sealing performance, which can prevent leakage gaps at the connection between the waterstop and the steel column, thereby further preventing roof leakage.

[0020] In one optional implementation, the material of the anti-leakage coating is a leak-stopping agent;

[0021] And / or, the material of the roof structure layer is concrete.

[0022] Beneficial effects: Leak-stopping compound is commonly used for waterproofing and leak sealing. It is a leak-proof material that integrates waterproofing, moisture-proofing, crack resistance, seepage resistance, and leak sealing. It can solidify quickly during use and has high strength after solidification. It is highly reliable, readily available, and easy to use.

[0023] Concrete roofing is the structural layer of a roof. Concrete roofing features high strength and durability. It is formed through casting, a mature technology, and has high reliability.

[0024] Secondly, this utility model also provides a building, including: the aforementioned steel column roof waterproofing structure. Since the building includes the steel column roof waterproofing structure, it has the same effect as the steel column roof waterproofing structure, and will not be described further here.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] In prefabricated steel structure buildings, it is common to see main structures extending above the roof, such as roof-mounted structural layers, roof-mounted machine rooms, and roof-mounted stairwells. In these roof-mounted structures, steel columns penetrate the roof structure. Due to temperature deformation of the steel columns and shrinkage and creep of the roof concrete, cracks easily form between the steel columns and the roof concrete structure, causing roof leaks and posing potential quality risks. Current methods either do not address this separately or simply apply waterproof coating after construction. Because steel columns deform significantly due to temperature, while concrete undergoes relatively small volume changes, their deformation is inconsistent, still easily leading to cracks at the junction of the steel column and the concrete roof, creating a potential leak. Furthermore, due to factors such as rainfall and snowfall, the junction between the steel column and the concrete roof is prone to corrosion, affecting building durability and structural safety, which is inconsistent with the concept of green development. Therefore, optimizing the steel column extension joint to eliminate potential leaks is crucial.

[0032] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0033] According to an embodiment of this utility model, a steel column roof waterproofing structure is provided, comprising: a roof structural layer 4, a steel column 1, a waterstop plate 2, and a waterproofing coating 6. The steel column 1 penetrates the roof structural layer 4 along its thickness direction; the waterstop plate 2 is annular, surrounding and fixedly connected to the steel column 1, and is located within the roof structural layer 4; the waterproofing coating 6 is applied to the outer side of the roof structural layer 4, and is scraped onto the joint between the steel column 1 and the roof structural layer 4, surrounding the steel column 1. It should be noted that the steel column roof waterproofing structure is a structure on a building, and the outer side of the roof structural layer 4 refers to the outer side of the building. Further combined with... Figure 1 As shown, the steel column 1 extends vertically, and the outer side of the roof structure layer 4 refers to the upper side, that is, along... Figure 1 The direction indicated by the middle arrow is the side in the direction of "up"; the thickness direction refers to... Figure 1 The direction indicated by the middle arrow is "up and down".

[0034] The building waterproofing structure of this embodiment uses an annular waterstop plate 2 connected to the outer surface of the steel column 1. The waterstop plate 2 extends away from the steel column 1 along a direction perpendicular to the center line of the steel column 1, thus extending the leakage path. The waterstop plate 2 is located within the roof structure layer 4, without affecting the building's appearance. The roof structure layer 4 provides protection for the waterstop plate 2, preventing damage and increasing structural reliability. Simultaneously, an anti-leakage coating 6 is added at the joint between the roof structure layer 4 and the steel column 1 as a waterproofing and leak-stopping material. When small cracks appear, the anti-leakage coating 6 seals them, forming an extra layer of protection. Furthermore, the combination of the anti-leakage coating 6 and the waterstop plate 2 increases the difficulty of leakage, preventing easy leakage between the steel column 1 and the roof structure layer 4, thereby avoiding safety hazards caused by leakage. The annular waterstop plate 2 has a simple structure and can be directly assembled with the steel column 1, facilitating assembly and modularization, making construction convenient and promoting industrial production.

[0035] It should be noted that steel column 1 is a structural column in prefabricated steel structure buildings, and square columns are commonly selected, further combined with... Figure 2 As shown, the waterstop 2 is a square ring connected to the outer periphery of the steel column 1. It can be understood that, as an alternative implementation, the steel column 1 can also be a cylinder, in which case the waterstop 2 is a ring.

[0036] In one embodiment, the waterstop 2 is made of steel plate. Steel plate has high structural strength and reliability, and the material is readily available and inexpensive. Specifically, the annular waterstop 2 is made of steel plate with a width of 100mm to 250mm and a thickness of 15mm to 30mm.

[0037] In one embodiment, the waterstop 2 is welded to the steel column 1. By welding the waterstop 2 to the steel column 1, a stable connection between the waterstop 2 and the steel column 1 can be ensured. The welding has high reliability and good sealing performance, which can prevent leakage gaps from forming at the connection between the waterstop 2 and the steel column 1, thereby further preventing roof leakage.

[0038] Preferably, the waterstop 2 is fully welded to the steel column 1, that is, the entire inner ring of the waterstop 2 is welded to the steel column 1, and all contact parts between the waterstop 2 and the steel column 1 are fused welded, which can achieve a seamless connection between the waterstop 2 and the steel column 1, thereby further increasing the waterproof performance of the structure.

[0039] In one embodiment, the roof structural layer 4 is made of concrete. The concrete roof is the structural layer of the roof, possessing high strength and durability. It is manufactured through a mature casting process, ensuring high reliability. It should be noted that during the concrete pouring, the concrete encases the waterstop 2, bonding the waterstop 2 with the concrete and facilitating its fixation to the roof structural layer 4. This ensures waterproofing and leak prevention within the roof structural layer, further enhancing reliability.

[0040] In one embodiment, the steel column roof waterproofing structure further includes a structural beam 3, which is disposed on the side of the roof structural layer 4 opposite to the waterproof coating 6. It should be noted that the structural beam 3 is typically located inside the building. The structural beam 3 connects to the steel column 1 to form a steel structural frame, serving a load-bearing function to support the roof structural layer 4. By setting the structural beam 3 to support the roof structural layer 4, the reliability of the main building structure is ensured.

[0041] In one embodiment, structural beam 3 is a steel beam, which is a structural beam of a prefabricated steel structure building. The steel beam has high structural strength and high reliability. The steel beam and steel column work together to form the main body of the steel structure.

[0042] In one embodiment, the steel column roof waterproofing structure further includes a mortar-lined base 5, which is located at the corner formed by the intersection of the outer surface of the roof structural layer 4 and the outer periphery of the steel column 1, and the mortar-lined base 5 is covered with a waterproofing coating 6. It should be noted that the outer surface of the roof structural layer 4 refers to the surface of the roof structural layer 4 facing the outside of the building, i.e., the upper surface of the roof structural layer 4. The upper surface refers to... Figure 1The surface in the direction indicated by the middle arrow ("up"); the part where the steel column 1 connects to the outer surface of the roof structure layer 4 is the column base, where water easily accumulates. By setting a mortar-lined base 5 at the intersection of the outer surface of the roof structure layer 4 and the outer perimeter of the steel column 1, corrosion of the steel column base is prevented, increasing structural durability and aligning with the concepts of green building and green development. Furthermore, by covering the anti-seepage coating 6 with the mortar-lined base 5, the protective effect of the anti-seepage coating 6 is increased. Thus, the combination of the mortar-lined base 5 and the anti-seepage coating 6 further strengthens the anti-seepage effect at the junction of the roof structure layer 4 and the steel column 1, eliminating the safety hazards caused by leakage and corrosion of the steel column at the junction of the steel column 1 and the roof structure layer 4.

[0043] In one embodiment, the mortar-covered foot 5 has a width of 100mm to 150mm and a height of 50mm to 150mm. The height being in the same direction as the centerline of the steel column 1 means along... Figure 1 The dimensions in the "up and down" direction indicated by the middle arrow; the mortar foot 5 is set around the steel column 1, and the orthographic projection of the mortar foot 5 on the roof structure layer 4 in the up and down direction is a ring. The width refers to the ring width of the orthographic projection of the mortar foot 5 on the roof structure layer 4.

[0044] In one embodiment, the steel column roof waterproofing structure further includes: sealant 7, which is applied to the junction of the mortar base 5 and the steel column 1. By applying sealant 7 to the junction of the mortar base 5 and the steel column 1, cracks are prevented between the mortar base 5 and the steel column 1, further improving the waterproofing effect.

[0045] In one embodiment, sealant 7 is an elastic, weather-resistant, and waterproof material. It should be noted that weather resistance refers to the ability of a material or product to resist aging phenomena such as fading, discoloration, cracking, and chalking when exposed to sunlight, temperature changes, wind, rain, and other natural environments over a long period. By setting sealant 7 as an elastic, weather-resistant, and waterproof material, sealant 7 possesses excellent anti-aging and waterproof properties. Furthermore, when the steel column 1 and the roof structure layer 4 deform, and the deformation of the steel column and the concrete is inconsistent, the elastic sealant 7 can deform accordingly, promptly filling the cracks at the joint between the steel column 1 and the roof structure layer 4. This ensures that the entire steel column's roof waterproofing structure is free of cracks and gaps, achieving a water-stopping and seepage-proof effect.

[0046] In one embodiment, the mortar-covered foot 5 has a top surface 501 facing away from the roof structure layer 4. The top surface 501 is inclined relative to the roof structure layer 4, and the side of the top surface 501 away from the steel column 1 is lower than the side of the top surface 501 close to the steel column 1. Sealant 7 is applied at the junction of the top surface 501 and the steel column 1. The top surface 501 is the edge of the mortar-covered foot 5. Figure 1The surface on the side indicated by the middle arrow pointing to the "up". By setting the top surface 501 of the mortar foot 5 at an angle relative to the roof structure layer 4, that is, the top of the mortar foot 5 is a slope, it is easy for water to flow smoothly down the slope, which can prevent water from accumulating on the top of the mortar foot 5, thereby reducing the soaking of the sealant 7, extending the service life of the sealant 7, and further improving the water-stopping and seepage prevention effect.

[0047] In one embodiment, the material of the anti-leakage coating 6 is a leak-stopping compound. Leak-stopping compound is commonly used for waterproofing and leak sealing. It is an anti-leakage material that integrates waterproofing, moisture resistance, crack resistance, seepage prevention, and leak sealing. It solidifies quickly during use and has high strength after solidification. It is highly reliable, readily available, and easy to use.

[0048] The steel column roof waterproofing structure in this embodiment does not change the original steel structure and roof structure, and the steel columns and beams of the prefabricated building can be constructed normally. A ring-shaped waterstop 2 is welded circumferentially to the steel column 1 at the position corresponding to the roof structural layer 4. The waterstop 2 surrounds the steel column 1. During the concrete pouring of the roof structural layer 4, the waterstop 2 bonds with the concrete, providing waterproofing and leak prevention at the structural level. After the concrete pouring of the roof structural layer 4 is completed, a 30mm-50mm thick layer of sealant is applied around the bottom of the steel column 1. This seals any minor cracks, providing an extra layer of protection. Then, mortar is used to wrap the base of the steel column 1 to prevent corrosion and increase structural durability, aligning with green building and green development concepts. Finally, at the junction of the top surface 501 of the mortar-wrapped base and the steel column 1, an elastic weather-resistant sealant 7 is applied to further prevent cracking. When the steel column 1 and the concrete deform inconsistently, the sealant 7 deforms accordingly, ensuring that no cracks or gaps appear in the roof waterproofing structure, achieving a waterproofing and leak-proof effect.

[0049] The anti-leakage structure of the steel column protruding from the roof in this embodiment extends the leakage path by welding a water-stop steel plate around the steel column 1, adding an anti-leakage coating 6 at the joint between the steel column 1 and the roof structure layer 4, and adding mortar to the column base 5, etc., to eliminate the potential leakage at the joint between the steel column 1 and the roof structure layer 4, prevent the column base from rusting, and avoid the safety hazards caused by roof leakage and steel column corrosion.

[0050] The steel column roof-extension waterproofing structure in this embodiment solves the problems of hollowness, cracking and easy leakage at the steel column roof-extension node through optimized design and construction. It adopts a standardized and modular design, requires no complicated process, is highly compatible with industrialized construction process, has high versatility, is applicable to various steel column extension roof structures, and greatly meets the requirements of standardized production.

[0051] The steel column roof waterproofing structure in this embodiment is simple in structure, requires no complex skills, and does not increase the workload of construction workers. All materials used are common on-site materials and are readily available environmentally friendly. Without significantly increasing costs, it significantly improves waterproofing performance, effectively prevents corrosion at the column base, increases structural durability, and achieves excellent results. It reduces resource consumption and environmental pollution, fully embodying the concepts of industrialized and green building. Practice has proven that the steel column roof waterproofing structure in this embodiment significantly improves project quality and waterproofing reliability, greatly increases the durability of the steel column base, and delays corrosion.
