Description

Technical Field

[0001] The present application relates to the technical field of factory floor, and in particular to a factory floor with an ultra-large area and a solidification construction method thereof. Background Art

[0002] With the rapid development of industry, the design and construction of large-scale factory floors are facing higher and higher requirements. These requirements include not only that the floor must be able to withstand heavy loads and frequent traffic, but also involve the flatness, durability, sealing and aesthetics of the floor. Modern industrial production has continuously improved the requirements for the internal environment of the factory. As an important part of the factory, the performance of the floor directly affects the production efficiency and product quality. Therefore, developing a floor curing construction method suitable for ultra-large-area factories is of great significance to improving the efficiency of factory use and the quality of the production environment.

[0003] At present, the construction of large-scale factory floors generally adopts the method of pouring concrete in blocks. Although this traditional method meets the load-bearing and durability requirements of the floor to a certain extent, it also exposes some limitations. Especially in the construction of ultra-large areas, due to the shrinkage and temperature changes of concrete during the curing process, cracks are prone to appear on the floor. These cracks not only affect the appearance of the floor, but may also damage the structural integrity and durability of the floor, thereby increasing long-term maintenance costs and potential production risks.

[0004] Since the ground construction area of ​​large factory buildings is large, a continuous and flat surface needs to be maintained during the construction process. The shrinkage and temperature changes of concrete during the curing process may cause the continuous and flat surface to crack, thereby forming cracks on the surface, which not only affects the appearance of the floor, but may also damage the structural integrity and durability of the floor. Summary of the invention

[0005] The purpose of this application is to solve the problem that shrinkage and temperature changes of concrete during the curing process may cause cracks, thereby damaging the structural integrity and durability of the floor. This application provides a large-area factory floor and its curing construction method.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A factory floor with an extra-large area comprises a gravel base layer, a concrete cushion layer is cast on the top of the gravel base layer, a waterproof membrane layer is laid on the top of the concrete cushion layer, a cast-in-place slab layer is cast on the top of the waterproof membrane layer, a sealing surface layer is laid on the top of the cast-in-place slab layer, a first grid steel frame is fixedly connected to the inside of the concrete cushion layer, a second grid steel frame is fixedly connected to the inside of the cast-in-place slab layer, and a compaction component for reducing ground deformation is arranged on the periphery of the gravel base layer.

[0007] By adopting the above technical scheme, by setting up the coordinated use of concrete cushion layer, cast-in-place slab layer, grid steel frame and compaction component, the double-layer foundation setting of concrete cushion layer and cast-in-place slab layer is made, which effectively improves the bearing stability and impermeability of the ground, reduces the impact of uneven settlement of gravel base layer on the ground, and at the same time, grid steel frame is set to strengthen the internal structural strength of concrete cushion layer and cast-in-place slab layer, and when the top of cast-in-place slab layer bears a large weight, the cast-in-place slab layer cooperates with the compaction component to squeeze the side of the gravel base layer, and pushes the gravel base layer to be compacted and gathered in the middle, so as to further improve the bearing strength of the ground, reduce the occurrence of cracks in the ground, and enhance the integrity of the ground.

[0008] Furthermore, microfiber material is added inside the cast-in-place slab layer.

[0009] By adopting the above technical solution, by setting up microfiber materials and utilizing their excellent toughness and ductility to form a network structure, the bonding force between materials is enhanced, stress is effectively absorbed and dispersed, and the formation of cracks is reduced.

[0010] Furthermore, the waterproof membrane layer is configured as a high-density polyethylene waterproof membrane.

[0011] By adopting the above technical solution, the waterproof effect of the ground is effectively improved by setting the waterproof roll material layer to a high-density polyethylene waterproof roll material.

[0012] Furthermore, the sealing surface layer is made of polyurethane material.

[0013] By adopting the above technical solution and providing a sealing surface layer made of polyurethane material, the impermeability and dustproofness of the ground surface are effectively improved.

[0014] Furthermore, the compaction assembly includes an annular base wall fixedly connected to the periphery of the gravel base layer, a concrete compaction ring is cast on the periphery of the cast-in-place slab layer, one end of the second grid steel frame extends to the interior of the concrete compaction ring, and a telescopic filler is filled between the gravel base layer and the annular base wall, and the telescopic filler is installed below the concrete compaction ring.

[0015] By adopting the above technical scheme, by setting up the coordinated use of the annular foundation wall, the telescopic filler and the concrete compaction ring, when the cast-in-place slab layer and the concrete cushion layer bear a heavy weight, the telescopic filler can be pushed downward by the second grid steel frame to squeeze the side of the gravel base layer, and the gravel base layer is pushed to be compacted and gathered in the middle with the four side surfaces as the force surfaces, and at the same time, the telescopic filler is deformed by the force and forms a conflict with the inner side of the annular foundation wall, thereby reducing the situation where the gravel base layer, the concrete cushion layer and the cast-in-place slab layer collapse to the surroundings when bearing a heavy weight and cause cracks in the ground, thereby extending the service life of the ground.

[0016] Furthermore, a geotextile cover is fixedly connected between the crushed stone base layer and the bottom of the telescopic filler, and one end of the geotextile cover extends between the telescopic filler and the annular foundation wall.

[0017] By adopting the above technical scheme, by setting up the coordinated use of the geotextile cover with the crushed stone base and the telescopic filler, it is convenient to use the geotextile cover to filter and intercept the water flow passing through the crushed stone base and the telescopic filler, so that the internal raw materials of the crushed stone base and the telescopic filler are intercepted by the geotextile cover and retained in the crushed stone base or the telescopic filler, thereby effectively reducing the soil and water loss inside the crushed stone base and the telescopic filler and improving the stability and integrity of the ground.

[0018] A method for solidifying the floor of a large-scale factory building, the steps of the method are as follows: S1: First, a foundation pit is excavated and a circular foundation wall is cast inside the foundation pit to provide support for the ground structure; S2: Lay a geotextile cover at the bottom of the foundation pit to reduce soil erosion; S3: Lay a crushed stone base on top of the geotextile cover to provide a solid foundation for the ground; S4: Lay the first grid steel frame on the top of the gravel base, and pour the concrete cushion layer. At the same time, lay the waterproof membrane layer on the top of the concrete cushion layer to enhance the waterproof effect and the rigidity of the ground and prevent the rise of groundwater and moisture. S5: laying a second mesh steel frame on the top of the waterproof membrane layer, and pouring a cast-in-place slab layer, while adding microfiber material inside the cast-in-place slab layer, so that the cast-in-place slab layer, the second mesh steel frame and the microfiber material are integrated into one; S5: Fill the expansion filler between the gravel base and the annular foundation wall, and at the same time pull one end of the geotextile cover to extend between the annular foundation wall and the expansion filler to reduce the impact of water scouring on the gravel base and the expansion filler; S6: Pour a concrete compaction ring around the outer periphery of the cast-in-place slab layer and fix it to the top of the telescopic filler so that the cast-in-place slab layer forms a conflict with the side of the crushed stone base through the telescopic filler to reduce cracking.

[0019] S7: Lay a sealing surface layer on the top of the cast-in-place slab to enhance its impermeability, dustproofness and aesthetics; S8: After completing all construction steps, conduct final inspection and acceptance to ensure the stability and usability of the ground.

[0020] Furthermore, during the pouring of the concrete cushion layer and the cast-in-place slab layer, a vibrating rod is used for vibration.

[0021] Furthermore, when pouring the cast-in-place slab layer, a floor trowel is used to perform multiple passes of troweling.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. By setting up a concrete cushion layer, a cast-in-place slab layer, a grid steel frame, and a compaction component, a double-layer foundation setting of a concrete cushion layer and a cast-in-place slab layer is made, which effectively improves the bearing stability and impermeability of the ground, and reduces the impact of uneven settlement of the gravel base on the ground. At the same time, a grid steel frame is set to strengthen the internal structural strength of the concrete cushion layer and the cast-in-place slab layer. When the top of the cast-in-place slab layer bears a large weight, the cast-in-place slab layer cooperates with the compaction component to squeeze the side of the gravel base layer, and push the gravel base layer to be compacted and gathered in the middle, so as to further improve the bearing strength of the ground, reduce the occurrence of cracks in the ground, and enhance the integrity of the ground.

[0023] 2. By setting up the annular foundation wall in conjunction with the telescopic filler and the concrete compaction ring, when the cast-in-place slab layer and the concrete cushion layer bear a large weight, the telescopic filler can be pushed downward by the second grid steel frame to squeeze the side of the gravel base layer. At the same time, the telescopic filler is deformed by the force and forms a conflict with the inner side of the annular foundation wall, thereby reducing the situation where the gravel base layer, the concrete cushion layer and the cast-in-place slab layer collapse in all directions after being stressed. At the same time, the deformation characteristics of the telescopic filler are used to reduce the hard conflict between the cast-in-place slab layer, the concrete cushion layer and the annular foundation wall, thereby improving the bearing strength of the annular foundation wall and extending the service life of the ground.

[0024] 3. By setting up the geotextile cover in conjunction with the crushed stone base and the telescopic filler, it is convenient to use the geotextile cover to filter and intercept the water flow passing through the crushed stone base and the telescopic filler, so that the internal raw materials of the crushed stone base and the telescopic filler are intercepted by the geotextile cover and retained in the crushed stone base or the telescopic filler, thereby effectively reducing the soil and water loss inside the crushed stone base and the telescopic filler, and improving the stability and integrity of the ground.

[0031] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0032] The embodiments of the present application disclose a large-area factory floor and a solidification construction method thereof.

[0033] Reference Figure 1-Figure 3 , a super-large area factory floor, comprising a gravel base layer 1, a concrete cushion layer 2 is cast on the top of the gravel base layer 1, a waterproof membrane layer 3 is laid on the top of the concrete cushion layer 2, a cast-in-place slab layer 4 is cast on the top of the waterproof membrane layer 3, a sealing surface layer 5 is laid on the top of the cast-in-place slab layer 4, a first grid steel frame 6 is fixedly connected inside the concrete cushion layer 2, a second grid steel frame 7 is fixedly connected inside the cast-in-place slab layer 4, and a compaction component for reducing ground deformation is arranged on the periphery of the gravel base layer 1; Among them, microfiber material is added inside the cast-in-place slab layer 4; Moreover, the waterproofing coiled material layer 3 is provided as a high-density polyethylene waterproofing coiled material; Furthermore, the sealing surface layer 5 is made of polyurethane material.

[0034] When in use, firstly, a crushed stone base layer 1 is set to provide a stable support for the ground, and then a concrete cushion layer 2 is poured on the top of the crushed stone base layer 1 to prevent the rise of groundwater and moisture, while reducing the impact of uneven settlement of the crushed stone base layer 1 on the ground, and a waterproof membrane layer 3 composed of a high-density polyethylene waterproof membrane is laid on the top of the concrete cushion layer 2 to improve the waterproof effect of the ground; Then, a cast-in-place slab layer 4 is poured on the top of the waterproof membrane layer 3 to provide the main bearing capacity of the ground, and then a sealing surface layer 5 made of polyurethane material is laid on the top of the cast-in-place slab layer 4 to enhance the impermeability and dustproofness of the ground, and enhance the durability and aesthetics of the ground; In the process of pouring the concrete cushion layer 2 and the cast-in-place slab layer 4, a vibrating rod or a flat vibrator is used to vibrate the concrete to reduce the gaps inside the concrete cushion layer 2 and the cast-in-place slab layer 4, so that the concrete cushion layer 2 and the cast-in-place slab layer 4 are poured more densely. At the same time, a first grid steel frame 6 is added in the process of pouring the concrete cushion layer 2 and the cast-in-place slab layer 4 to improve the structural strength of the concrete cushion layer 2 and the cast-in-place slab layer 4, improve the bearing strength of the ground, and reduce the cracking of the internal structure of the concrete cushion layer 2 and the cast-in-place slab layer 4; In the process of pouring the cast-in-place slab layer 4, microfiber material is added to absorb and disperse stress by utilizing the good toughness and ductility of the microfiber material. At the same time, the microfiber forms a mesh structure inside the cast-in-place slab layer 4, thereby strengthening the bonding force of the internal structure of the cast-in-place slab layer 4 and further reducing the occurrence of cracks in the internal structure of the cast-in-place slab layer 4. Then, when the top of the cast-in-place slab 4 bears a heavy weight, the cast-in-place slab 4 transfers the weight to the side of the gravel base layer 1 through the compaction assembly, and the side of the gravel base layer 1 is stressed and compacted and gathered toward the middle, thereby effectively reducing the situation where the gravel base layer 1 spreads around after being stressed, further improving the compression resistance and integrity of the ground, and reducing the cracking of the ground.

[0035] Reference Figure 2 and Figure 4 , Figure 5 The compaction assembly includes an annular foundation wall 8 fixedly connected to the periphery of the crushed stone base layer 1, a concrete compaction ring 10 is cast on the periphery of the cast-in-place slab layer 4, one end of the second grid steel frame 7 extends to the interior of the concrete compaction ring 10, and a telescopic filler 9 is filled between the crushed stone base layer 1 and the annular foundation wall 8, and the telescopic filler 9 is installed below the concrete compaction ring 10.

[0036] When in use, firstly, a layer of annular foundation wall 8 is fixed on the periphery of the crushed stone base layer 1, so that the annular foundation wall 8 wraps and shapes the sides of the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4. When the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4 are deformed in all directions by force, the crushed stone base layer 1, the concrete cushion layer 2, the cast-in-place slab layer 4, and the inner side of the annular foundation wall 8 are in conflict, thereby reducing the situation that the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4 collapse in all directions after being stressed. Then, when the top of the cast-in-place slab layer 4 is subjected to force to squeeze the concrete cushion layer 2 and the gravel base layer 1 downward, the cast-in-place slab layer 4 pulls the second grid steel frame 7 to drive the concrete compaction ring 10 to apply pressure downward, and the concrete compaction ring 10 pushes the telescopic filler 9 to squeeze the side of the gravel base layer 1, thereby pushing the gravel base layer 1 to be compacted and gathered in the middle with four side surfaces as force surfaces, so that the cast-in-place slab layer 4 pushes the gravel base layer 1 to be compacted in the middle when bearing a large weight, so as to reduce the situation where the gravel base layer 1 collapses to the surroundings when bearing a large weight and causes cracks in the ground; When the cast-in-place slab layer 4 and the concrete cushion layer 2 are deformed due to bearing heavy weight, the cast-in-place slab layer 4 drives the concrete compaction ring 10 to squeeze the telescopic filler 9 from the top through the second grid steel frame 7. At the same time, the side of the concrete cushion layer 2 directly squeezes the telescopic filler 9, and utilizes the shrinkage characteristics of the telescopic filler 9 to deform with the extrusion force applied by the cast-in-place slab layer 4 and the concrete cushion layer 2, thereby reducing the rigid conflict between the cast-in-place slab layer 4 and the concrete cushion layer 2 deformed due to bearing heavy weight and the annular foundation wall 8, thereby improving the bearing strength of the annular foundation wall 8 and extending the service life of the ground.

[0037] Reference Figure 1 and Figure 2 A geotextile cover 11 is fixedly connected between the crushed stone base layer 1 and the bottom of the telescopic filler 9 , and one end of the geotextile cover 11 extends between the telescopic filler 9 and the annular foundation wall 8 .

[0038] When in use, first lay a geotextile cover 11 inside the foundation, and then lay a gravel base layer 1 on the top of the geotextile cover 11, so that the geotextile cover 11 can be used to filter the underground water flow that is in direct contact with the gravel base layer 1, so as to reduce the water flow passing through the bottom of the gravel base layer 1 to scour the raw materials inside the gravel base layer 1, and reduce the loss of raw materials inside the gravel base layer 1. At the same time, one end of the geotextile cover 11 is pulled to extend between the telescopic filler 9 and the annular foundation wall 8, so that the geotextile cover 11 filters and intercepts the underground water flow flowing to the inside of the telescopic filler 9, so that the water flow passes through the geotextile cover 11 and flows away, while the internal raw materials of the telescopic filler 9 are filtered and intercepted by the geotextile cover 11 and remain in the telescopic filler 9, so as to reduce the loss of raw materials inside the telescopic filler 9, thereby effectively reducing the soil and water loss inside the gravel base layer 1 and the telescopic filler 9, and improving the stability and integrity of the ground.

S5: laying a second mesh steel frame 7 on the top of the waterproof membrane layer 3, and pouring the cast-in-place slab layer 4, while adding microfiber material inside the cast-in-place slab layer, so that the cast-in-place slab layer 4 is integrated with the second mesh steel frame 7 and the microfiber material; S5: Fill the telescopic filler 9 between the gravel base 1 and the annular foundation wall 8, and at the same time pull one end of the geotextile cover 11 to extend between the annular foundation wall 8 and the telescopic filler 9 to reduce the impact of water scouring on the gravel base 1 and the telescopic filler 9; S6: Cast a concrete compaction ring 10 on the periphery of the cast-in-place slab layer 4 and fix it to the top of the telescopic filler 9, so that the cast-in-place slab layer 4 forms a conflict with the side of the crushed stone base layer 1 through the telescopic filler 9 to reduce cracking.

[0040] S7: Laying a sealing surface layer 5 on the top of the cast-in-place slab layer 4 to enhance the impermeability, dustproofness and aesthetics; S8: After completing all construction steps, conduct final inspection and acceptance to ensure the stability and usability of the ground; Wherein, during the pouring process of the concrete cushion layer 2 and the cast-in-place slab layer 4, a vibrating rod is used for vibration; Furthermore, when pouring the cast-in-place slab layer 4, a floor trowel is used to perform multiple rounds of troweling.

[0041] The implementation principle of the ultra-large-area factory floor and its solidification construction method in this embodiment is as follows: first, a foundation pit is dug, and a circular foundation wall 8 is cast inside the foundation pit, and then a geotextile cover 11 is laid at the bottom of the foundation pit to reduce soil erosion, and then a crushed stone base layer 1 is laid on the top of the geotextile cover 11 to provide a solid foundation for the ground, and then a concrete cushion layer 2 is poured thereon, which not only enhances the rigidity of the ground, but also effectively prevents the rise of groundwater and moisture, and then a waterproof roll layer 3 composed of a high-density polyethylene waterproof roll is laid on the concrete cushion layer 2 to further enhance the waterproof effect of the ground; Then cast the cast-in-place slab layer 4, which is the main load-bearing part of the ground structure. Vibrate the concrete by using a vibrating rod or a flat plate vibrator to ensure that the concrete is dense and has no voids, thereby improving the overall strength and durability of the ground; Then, the telescopic filler 9 is filled between the crushed stone base layer 1 and the annular foundation wall 8, so that the bottom of the telescopic filler 9 is in conflict with the side of the crushed stone base layer 1, and then a layer of concrete compaction ring 10 fixedly connected to the top of the telescopic filler 9 is poured on the periphery of the cast-in-place slab layer 4, and one end of the second grid steel frame 7 is extended to the inside of the concrete compaction ring 10, so that the cast-in-place slab layer 4 and the concrete compaction ring 10 are connected as one, and at the same time, when the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4 are deformed in all directions under force, the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4 squeeze the telescopic filler 9 and the inner side of the annular foundation wall 8 to form a conflict, and squeeze the crushed stone base layer 1 from all directions to the middle for compaction, thereby reducing the situation where the crushed stone base layer 1, the concrete cushion layer 2, and the cast-in-place slab layer 4 collapse in all directions after being stressed; While filling the telescopic filler 9, one end of the geotextile cover 11 is pulled to extend between the telescopic filler 9 and the annular foundation wall 8, so that the geotextile cover 11 filters and intercepts the water flowing underground to the telescopic filler 9 and the gravel base 1, so that the water flows through the geotextile cover 11, and the internal raw materials of the telescopic filler 9 are filtered and intercepted by the geotextile cover 11, so that the internal raw materials of the gravel base 1 and the telescopic filler 9 are intercepted by the geotextile cover 11 and remain in the gravel base 1 or the telescopic filler 9, thereby effectively reducing the soil and water loss inside the gravel base 1 and the telescopic filler 9, and then a sealing surface layer 5 made of polyurethane material is laid on the top of the cast-in-place slab layer 4, which not only enhances the impermeability and dustproofness of the ground, but also improves the durability and aesthetics of the ground; A first grid steel frame 6 and a second grid steel frame 7 are added to the concrete cushion layer 2 and the cast-in-place slab layer 4 respectively. The setting of the first grid steel frame 6 and the second grid steel frame 7 helps to disperse stress and prevent the formation of cracks. Finally, microfiber material is added to the cast-in-place slab layer 4, and its excellent toughness and ductility are utilized to form a mesh structure, which enhances the bonding force between materials, effectively absorbs and disperses stress, and reduces the formation of cracks, thereby ensuring the long-term stability and performance of the ground.
