Description

Technical Field

[0001] The present application relates to the technical field of concrete floor structures, and in particular to a non-flammable and oil-proof concrete floor structure. Background Art

[0002] In the field of industrial buildings, most factory floors are made of concrete. For Class A factories that emit heavy flammable gases and Class B factories with dust and fiber explosion hazards, non-flammable concrete floors should be used because metal or hard stone objects are prone to sparks when they have mechanical effects such as friction and impact with the ground, which may cause flammable substances to cause explosions in fires.

[0003] Oil leakage often occurs in diesel generator sets and fire pump room oil supply standby units in industrial equipment rooms. Oil leakage into the ground will damage the concrete floor structure, thereby causing the non-flammable concrete floor to degrade or even lose its non-flammable function, and there is still a risk of causing accidents. Utility Model Content

[0004] In order to improve the problem of accident risks caused by oil leakage, the present application provides a non-flammable oil-proof concrete floor structure.

[0005] The non-fire-resistant oil-proof concrete floor structure provided in this application adopts the following technical solution:

[0006] A non-flammable oil-proof concrete floor structure comprises a base layer, an oil-proof layer and a non-flammable concrete surface layer which are arranged in sequence from bottom to top.

[0007] By adopting the above technical scheme, the base layer serves as the foundation of the building and plays a role in supporting the upper structure; the non-flammable concrete surface layer can prevent sparks from being emitted when the ground is subjected to mechanical impact, thereby increasing the fire resistance and safety of the ground structure; the provision of the oil-proof layer can prevent the oil from seeping into the base layer and damaging the ground structure when it leaks, thereby ensuring the non-flammable function of the non-flammable concrete surface layer.

[0008] Optionally, the oil-proof layer is a polyurethane oil-proof film.

[0009] By adopting the above technical solution, the polyurethane has good viscosity before it dries, and can form a good oil-proof and waterproof effect as an oil-proof layer. In addition, the polyurethane is colorless and odorless, and is safe and environmentally friendly to use as a waterproof layer.

[0010] Optionally, a pressure-resistant layer is provided between the base layer and the oil-proof layer, and the pressure-resistant layer is steel fiber concrete.

[0011] By adopting the above technical solution, adding steel fiber material to concrete can effectively prevent ground cracking and hollowing, so that the compression layer can withstand a larger load, prevent the ground from cracking due to the heavy load of heavy machinery and equipment on the ground, and improve the overall strength of the concrete floor structure.

[0012] Optionally, the upper surface of the pressure-resistant layer is inclined, and an oil collecting groove is provided at the lower end of the upper surface of the pressure-resistant layer. The oil collecting groove extends in the transverse direction, and a filter screen is provided on the top of the oil collecting groove.

[0013] By adopting the above technical scheme, the upper surface of the pressure-resistant layer is inclined so that the oil-proof layer is also inclined along with the pressure-resistant layer. The oil that penetrates into the upper surface of the oil-proof layer flows down to the oil collecting tank under the action of gravity and is collected and stored, thereby reducing the probability of the non-flammable concrete surface layer on the upper part of the oil-proof layer being soaked and damaged by the oil, and extending the service life of the concrete floor; the setting of the filter plate can prevent impurities from entering the oil collecting tank.

[0014] Optionally, the width of the top of the oil collecting tank is smaller than the width of the bottom, and a drain pipe is provided on the oil collecting tank.

[0015] By adopting the above technical solution, the width of the top of the oil collecting tank is set to be smaller than the width of the bottom, so that the oil collecting tank can be stably embedded in the pressure-resistant layer, reducing the up and down shaking of the oil collecting tank, thereby making it difficult for the oil to leak from the oil collecting tank; the setting of the drain pipe enables the staff to regularly discharge the oil collected and stored in the oil collecting tank through the drain pipe to avoid oil overflow.

[0016] Optionally, a protective layer is provided between the compression-resistant layer and the base layer, and the protective layer is a fine stone concrete layer.

[0017] By adopting the above technical solution, the protective layer is cast with concrete having a strength higher than that of the base layer, which can provide protection for the base layer. At the same time, the fine stone concrete layer can play a waterproof role to a certain extent, reducing the probability of underground water vapor infiltrating upward from the base layer.

[0018] Optionally, an isolation layer is provided between the pressure-resistant layer and the protective layer, and the isolation layer is a PE waterproof film.

[0019] By adopting the above technical solution, the isolation layer made of PE waterproof membrane can completely block water vapor, prevent underground water vapor from infiltrating upward and damaging the concrete floor, and extend the service life of the concrete floor.

[0020] Optionally, a non-flammable epoxy floor layer is provided on the non-flammable concrete surface layer.

[0021] By adopting the above technical scheme, the non-flammable epoxy floor layer is usually made of epoxy floor paint with waterproof water-based coating, which can play a buffering and protective role on the non-flammable concrete surface layer, and is non-flammable itself, and has the effects of fire prevention, waterproof and oil resistance.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The coordinated arrangement of the base layer, the oil-proof layer and the non-inflammable concrete surface layer can prevent the concrete floor structure of the present application from emitting sparks when subjected to mechanical impact, thereby improving the fireproof performance. In addition, due to the arrangement of the oil-proof layer, the probability of damage caused by water and oil in the concrete floor structure due to oil and water leakage can be reduced, thereby ensuring the fireproof function of the non-inflammable concrete surface layer;

[0024] 2. Polyurethane oil-proof film is used as a waterproof layer, which has strong viscosity and good waterproof effect. In addition, since polyurethane is colorless and odorless, its use as a waterproof layer meets the requirements of safety and environmental protection;

[0025] 3. The inclined pressure-resistant layer on the upper surface and the coordinated setting of the oil collecting trough can make the oil on the upper surface of the oil-proof layer flow into the oil collecting trough and be stored under the action of gravity, reducing the probability of the non-flammable concrete surface layer above the oil-proof layer being soaked in oil and damaged and failing, thereby extending the service life of the concrete floor.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a non-flammable oil-proof concrete floor structure. Figure 1 The non-flammable oil-proof concrete floor structure includes a base layer 1, a protective layer 2, an isolation layer 3, a compression layer 4, an oil-proof layer 5 and a non-flammable concrete surface layer 6. The base layer 1 includes a compacted layer 11, a cushion layer 12 and a foundation raft 13 arranged from bottom to top. The compacted layer 11 is compacted with plain soil, and the compaction coefficient is 0.97; the cushion layer 12 is cast with 100mm thick C15 concrete, C15 represents the concrete strength grade, the same below; the foundation raft 13 is a 500mm thick reinforced concrete raft. The common arrangement of the compacted layer 11, the cushion layer 12 and the foundation raft 13 makes the base layer 1 have a high strength and can provide good support and protection for the upper ground structure.

[0032] The protective layer 2 is located on the upper surface of the foundation raft 13. The protective layer 2 is cast and leveled with 50mm thick C20 concrete. The protective layer 2 uses concrete with a strength grade higher than that of the foundation raft 13 to protect the base layer 1. The isolation layer 3 is located on the upper surface of the protective layer 2. The isolation layer 3 is paved with a 0.25mm thick PE film. The isolation layer 3 is used to block the return of underground water and moisture to prevent the ground from being soaked due to excessive moisture content. The compression layer 4 is cast and formed with 250mm thick C30 steel fiber concrete. The steel fiber concrete is cast and leveled as it is cast to ensure the flatness of the upper surface of the compression layer 4. Adding steel fiber material to concrete can effectively prevent cracking and hollowing of the ground. The setting of the compression layer 4 can prevent the ground from cracking due to the heavy load of heavy machinery and equipment on the upper ground.

[0033] After the steel fiber concrete construction is completed and people can go on it, the moisture content of the compression layer 4 is tested. After the test is qualified, the oil-proof layer 5 is set on the upper surface of the compression layer 4. The oil-proof layer 5 is coated with liquid polyurethane to form a polyurethane oil-proof film. The thickness of the polyurethane oil-proof film is not less than 1.5mm. As a waterproof and oil-proof material, polyurethane material has good oil-proof effect, is colorless and odorless, and is safe and environmentally friendly to use. The non-fireable concrete surface layer 6 is set on the upper surface of the oil-proof layer 5. The aggregate used to configure the non-fireable concrete is natural mineral limestone or dolomite, and its particle size should be 0.15-30mm. The aggregate texture should be hard and the surface should be rough. If it is soft, the grain size should be adjusted. Pour 40mm thick C20 fine stone concrete, quickly and evenly spread it to the basic level and vibrate it to make it dense. Pay special attention to the blind areas such as the edge of the template, the wall, and the foot of the column, which need to be vibrated.

[0034] The provision of the non-inflammable concrete surface layer 6 can prevent the ground surface from being mechanically impacted to generate sparks, thereby reducing the risk of fire. The provision of the oil-proof layer 5 can prevent the leaked oil from seeping downward and damaging the ground structure below the oil-proof layer 5, thereby ensuring the stability of the ground structure and the non-inflammable function of the non-inflammable concrete surface layer 6.

[0035] In addition, in order to timely discharge the oil above the oil-proof layer 5, the top surface of the pressure-resistant layer 4 is inclined at an angle of 1° to 5°, and 3° is used in this application. The bottom surface of the non-inflammable concrete surface layer 6 is consistent with the angle of the top surface of the pressure-resistant layer 4. Since the oil-proof layer 5 is brushed on the upper surface of the pressure-resistant layer 4, the oil-proof layer 5 is also inclined at 3°. The oil that penetrates through the non-inflammable concrete surface layer 6 slides down along the upper surface of the oil-proof layer 5 under the action of gravity and gathers at the lower end of the oil-proof layer 5, reducing the probability of oil soaking the non-inflammable concrete surface layer 6 and causing damage to the non-inflammable concrete surface layer 6, thereby ensuring the non-inflammable function of the non-inflammable concrete surface layer 6.

[0036] Reference Figure 2 , an oil collecting trough 7 is pre-set at the lower end of the upper surface of the pressure-resistant layer 4. The oil collecting trough 7 is pre-set in the pressure-resistant layer 4 when the pressure-resistant layer 4 is cast and formed, and the oil collecting trough 7 extends in the transverse direction. The oil collecting trough 7 is made of stainless steel, the top of the oil collecting trough 7 is open, and the top cover of the oil collecting trough 7 is provided with a filter screen plate 71, and the filter screen plate 71 is flush with the upper surface of the pressure-resistant layer 4; a drain pipe 72 is connected to the oil collecting trough 7. The oil flowing down from the upper surface of the oil-proof layer 5 enters the oil collecting trough 7 through the filter screen plate 71 and is collected. It is only necessary to regularly discharge the oil collected in the oil collecting trough 7 by connecting the drain pipe 72 through the pump body. Furthermore, in order to increase the stability of the setting of the oil collecting trough 7, the width of the top of the oil collecting trough 7 is smaller than the width of the bottom. The setting of the oil collecting trough 7 being narrow at the top and wide at the bottom can reduce the possibility of the oil collecting trough 7 shaking up and down, ensure the stability of the installation of the oil collecting trough 7, and reduce the possibility of oil leakage from the oil collecting trough 7.

[0037] Reference Figure 1 Furthermore, in order to enhance the oil-proof effect of the non-flammable oil-proof concrete floor, a non-flammable epoxy floor layer 8 is provided on the non-flammable concrete surface layer 6, and the non-flammable epoxy floor layer 8 is formed by brushing epoxy floor paint with waterproof water-based paint added.

[0038] The implementation principle of the non-inflammable oil-proof concrete floor structure of the embodiment of the present application is as follows: during construction, a base layer 1, a protective layer 2, an isolation layer 3, a pressure-resistant layer 4, an oil-proof layer 5, a non-inflammable concrete surface layer 6 and a non-inflammable epoxy floor layer 8 are formed in sequence from bottom to top. When the pressure-resistant layer 4 is cast, the upper surface is set to be inclined at 3°, and an oil collecting tank 7 is pre-set at the lower end of the upper surface of the pressure-resistant layer 4. The setting of the oil-proof layer 5 can block the infiltration of oil, prevent the infiltration of oil from causing damage to the concrete floor structure, and thus affect the non-inflammable function of the non-inflammable concrete surface layer 6. At the same time, the oil on the upper surface of the oil-proof layer 5 flows downward along the oil-proof layer 5 under the action of gravity into the oil collecting tank 7 and is collected, and can be discharged regularly through the oil drain pipe on the oil collecting tank 7, thereby reducing the probability of the non-inflammable concrete surface layer 6 losing its non-inflammable function due to the oil soaking.

[0039] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
