Description

TECHNICAL FIELD

[0001] The present application relates to the field of basement, in particular to a basement waterproof structure. BACKGROUND

[0002] Multi-storey and high-rise buildings require deeper foundations, and to make use of this height, basements are built under the ground floor of the building, which not only increases the usable area, but also saves backfilling. However, the basement is deeply buried underground, and the walls of the basement are prone to cracking under the static pressure of the soil and water, allowing water in the soil to seep into the interior of the basement.

[0003] At present, the related technology discloses a basement waterproof structure, which comprises a floor and a ceiling located above the floor. The top surface of the floor is fixedly installed with an outer wall and an inner wall in the circumferential direction. The inner wall is located inside the outer wall, and the top side of the outer wall and the top side of the inner wall are fixedly connected with the bottom surface of the ceiling. A plurality of support columns are fixedly installed between the inner wall of the outer wall and the outer wall of the inner wall, and the support columns are uniformly distributed on the outer wall of the inner wall. The outer wall bears the static pressure of the soil and water, and after the outer wall cracks, the water in the soil seeps into the space between the outer wall and the inner wall, thereby reducing the occurrence of the situation that the water in the soil seeps into the interior of the basement. Because the original single wall is split into an outer wall and an inner wall, the thickness of the outer wall and the inner wall is generally less than that of the original single wall, so the outer wall is supported by the support columns, thereby reducing the occurrence of the situation that the outer wall collapses under the extrusion of the soil and water.

[0004] According to the related technology in the above, the inventors believe that after the outer wall is extruded by the soil, the outer wall exerts pressure on the inner wall through the support columns, thereby easily causing the inner wall to crack. Then the water in the soil seeps into the space between the outer wall and the inner wall from the cracks of the outer wall, and then the water between the outer wall and the inner wall evaporates and enters the interior of the basement from the gaps of the inner wall. SUMMARY

[0005] In order to reduce the cracking of the inner wall, the present application provides a basement waterproof structure.

[0006] The basement waterproof structure provided by the present application adopts the following technical scheme:

[0007] The basement waterproof structure comprises a floor and a ceiling located above the floor, a top surface of the floor is fixedly installed with an outer wall body and an inner wall body in a circumferential direction, the inner wall body is located inside the outer wall body, a top side of the outer wall body and a top side of the inner wall body are fixedly connected with a bottom surface of the ceiling, a gap is left between the outer wall body and the inner wall body, the floor, the ceiling, the outer wall body and the inner wall body enclose a partition cavity, a plurality of sleeves are fixedly installed on an inner bottom wall of the partition cavity, the sleeves are arranged at intervals along the circumferential direction of the floor, the sleeves are provided with support rods, one end of each support rod is screwed into the sleeve, the other end of each support rod is fixedly inserted into the bottom surface of the ceiling, a plurality of support blocks are installed on the support rods, the support blocks are arranged at intervals along the length direction of the support rods, and the support blocks abut against the inner wall of the outer wall body.

[0008] By adopting the above technical scheme, the sleeve is inserted into the concrete after the floor is poured. After the concrete solidifies to form the floor, the sleeve is fixedly connected with the floor. Then, the formwork for pouring the outer wall body and the inner wall body is installed on the floor, and the concrete is poured to form the outer wall body and the inner wall body. The support rod is screwed into the sleeve, and the support block is installed on the support rod. The outer wall body is supported by the support block, thereby reducing the cracking of the outer wall body caused by the extrusion of the soil layer. Meanwhile, the support rod and the support block do not contact the inner wall body. The extrusion of the outer wall body by the soil layer is not applied to the inner wall body through the support rod and the support block, thereby reducing the cracking of the inner wall body caused by the extrusion. In this way, the entry of water vapor into the basement is reduced. After the installation of the support block and the support rod is completed, the ceiling is poured on the top side of the outer wall body and the inner wall body. The support rod is pre-buried in the ceiling, so that the ceiling is fixedly connected with the support rod after the concrete solidifies. Through the ceiling and the support rod, the rotation of the support block caused by the extrusion of the outer wall body is reduced.

[0009] Optionally, one side of the support block is fixedly installed with a sliding block, a sliding groove is formed in the rod body of the support rod for the sliding block to slide up and down, a support strip is fixedly installed on the top side of the sliding block, and the support strip is located in the sliding groove.

[0010] By adopting the above technical scheme, the support rod is screwed into the sleeve first, and then the sliding block is inserted into the sliding groove, so that the support block is installed on the support rod. Then, the support rod is continuously screwed into the sleeve, so that the support block is tightly abutted against the inner wall of the outer wall body, thereby facilitating the support block to play a good supporting role on the outer wall body. The support strip is used to separate the adjacent two support blocks on the same support rod, thereby facilitating the interval installation of the support blocks on the support rod.

[0011] Optionally, the support rod is a hollow structure with open ends, the sliding groove is in communication with the interior of the support rod, first clamping grooves are formed on both sides of the sliding block for the two side walls of the sliding groove, and second clamping grooves are formed on both sides of the support strip for the two side walls of the sliding groove.

[0012] By adopting the above technical scheme, after the support block abuts against the outer wall, the support block is driven by the reaction force of the outer wall to move the sliding block to the interior of the support rod, so that the inner side wall of the first clamping groove abuts against the outer wall of the support rod, the inner side wall of the second clamping groove abuts against the outer wall of the support rod, and then the sliding block and the support strip block the part of the sliding groove below the ceiling. Then, when the concrete of the ceiling is poured, the concrete enters the interior of the support rod. The sliding block and the support rod are connected together by the concrete, thereby improving the firmness of the connection between the support block and the support rod.

[0013] Optionally, the support block is semicircular, and one side of the straight edge of the support block is connected with the support rod.

[0014] By adopting the above technical scheme, when the sleeve is installed on the floor, there may be errors, so that the distance between each support rod and the outer wall is different. By making the support block semicircular, each semicircular block can be tightly abutted against the outer wall after the support rod is rotated.

[0015] Optionally, one side of the arc edge of the support block is provided with a scraping strip, the scraping strip is vertically arranged, a connecting rod is fixedly installed on the strip body of the scraping strip, an expansion hole is formed in the support block from one side of the straight edge to one side of the arc edge for the expansion of the connecting rod, a limiting plate is fixedly installed on the end of the connecting rod away from the scraping strip, a first spring is fixedly installed between the limiting plate and the straight edge of the support block, and the first spring is sleeved on the connecting rod.

[0016] By adopting the above technical scheme, the first spring drives the limiting plate to move towards the straight edge of the support block, so that the connecting rod extends from the arc edge of the support block. During the rotation of the support rod into the sleeve, the support block gradually approaches the outer wall, so that the scraping strip scrapes the outer wall, thereby facilitating the mutual abutment of the support block and the outer wall. After the support block abuts against the outer wall, the scraping strip also abuts against the outer wall, thereby increasing the support force on the outer wall.

[0017] Optionally, the sleeve is fixedly installed with a first support plate, and the first support plate is fixedly connected with the top surface of the floor.

[0018] Through the above technical scheme, after the concrete floor is poured, the sleeve is placed in the concrete. The sleeve is suspended above the concrete by the first supporting plate, so as to reduce the occurrence of the sleeve settlement. Then, when the concrete is solidified to form the floor, the sleeve and the first supporting plate are connected with the floor. The outer wall body pushes the sleeve through the supporting block and the supporting rod, and the first supporting plate increases the connecting area of the sleeve and the floor, so as to reduce the occurrence of the floor cracking under the extrusion of the sleeve.

[0019] Optionally, the top end of the supporting rod is provided with a second supporting plate, the second supporting plate is provided with a through hole for the supporting rod to pass through, and the second supporting plate is fixedly connected with the bottom surface of the ceiling.

[0020] Through the above technical scheme, when the template is laid to form the ceiling, a hole is reserved for the supporting rod to be inserted into the ceiling. Then, the second supporting plate blocks the hole reserved by the template for the supporting rod to pass through, so as to reduce the leakage of concrete from the gap between the supporting rod and the hole reserved by the template. After the concrete is solidified to form the ceiling, the supporting rod is fixedly connected with the ceiling, and the second supporting plate is also fixedly connected with the ceiling, so as to increase the connecting strength between the supporting rod and the ceiling.

[0021] Optionally, the supporting rod is provided with a third supporting plate, the third supporting plate is located below the second supporting plate, a second spring is fixedly installed between the second supporting plate and the third supporting plate, and the second spring is sleeved on the supporting rod.

[0022] Through the above technical scheme, the second supporting plate is driven away from the third supporting plate by the second spring, so as to conveniently abut against the bottom side of the template for pouring the ceiling.

[0023] Optionally, the outer wall body is provided with a water collecting tank, a drain pipe is fixedly installed between one side of the water collecting tank and the outer wall of the outer wall body, the inside of the water collecting tank is communicated with the partition cavity through the drain pipe, a ventilation pipe is fixedly installed on the top side of the water collecting tank, and a ventilator is installed on the end of the ventilation pipe away from the water collecting tank.

[0024] Through the above technical scheme, after the outer wall body cracks, part of the water enters the partition cavity from the cracks of the outer wall body. After the water in the partition cavity evaporates, the water vapor in the partition cavity is discharged through the ventilation pipe, the ventilator and the drain pipe, so as to reduce the occurrence of the water vapor in the partition cavity further penetrating into the basement from the inner wall body. At the same time, when it rains continuously for several days, more water penetrates into the partition cavity. The water in the partition cavity flows into the water collecting tank from the drain pipe, and after the rain stops, the water in the water collecting tank evaporates and is gradually discharged from the ventilation pipe, so as to facilitate keeping the partition cavity dry.

[0025] Optionally, a drain hole is arranged on the bottom side of the water collecting tank, a shielding plate is arranged on the inner bottom wall of the water collecting tank, a float is fixedly installed on the top surface of the shielding plate, a guide rod is fixedly installed on the top surface of the float, a guide ring is fixedly installed on the inner side wall of the water collecting tank, and the guide rod is arranged in the guide ring.

[0026] By using the above technical scheme, when the water in the water collecting tank is too much, the float drives the shielding plate to float up, and then the water in the water collecting tank is discharged from the drain hole, so that the water in the water collecting tank is conveniently discharged.

[0027] To sum up, the present application has at least one of the following beneficial technical effects:

[0028] 1. The support rod is installed on the floor through the sleeve, and then the support rod is rotated to make the support block tightly abut against the inner wall of the outer wall body to play a supporting role. When the outer wall body is extruded, the outer wall body will not extrude the inner wall body through the support block and the support rod, thereby reducing the occurrence of cracking of the inner wall body.

[0029] 2. When the support rod is rotated to drive the support block to tightly abut against the inside of the outer wall body, the scraping strip can scrape the inner wall of the outer wall body, thereby facilitating the mutual abutment of the support block and the inner wall of the outer wall body.

[0030] 3. After the outer wall body cracks, water seeps into the partition cavity from the cracks of the outer wall body, and the water in the partition cavity evaporates and is discharged through the drain pipe, the ventilation pipe and the ventilator, thereby reducing the aggregation of water in the partition cavity, and then the occurrence of corrosion of the inner wall body by the water aggregated in the partition cavity.

DETAILED DESCRIPTION

[0039] The following description will be made in conjunction with the accompanying drawings. Figures 1-7 The application is further described in detail.

[0040] The basement waterproof structure disclosed by the embodiments of the application.

[0041] Reference Figure 1 , Figure 2 A basement waterproof structure, comprising a floor 1 and a ceiling 2 located above the floor 1, and a top surface of the floor 1 is fixedly installed with an outer wall 3 and an inner wall 4 in a circumferential direction, the inner wall 4 is located inside the outer wall 3, and a gap is left between the outer wall 3 and the inner wall 4. The top side of the outer wall 3 and the top side of the inner wall 4 are fixedly connected with the bottom surface of the ceiling 2. The floor 1, the ceiling 2, the outer wall 3 and the inner wall 4 enclose a partition cavity 5.

[0042] The outer wall 3 is used to bear the static pressure of the soil layer and water. After the outer wall 3 cracks, water seeps into the partition cavity 5 from the outer wall 3. The water in the partition cavity 5 is hindered by the inner wall 4, so that the situation that water enters the inside of the basement occurs, thereby improving the waterproof performance of the basement.

[0043] Reference Figure 2 , Figure 3 The outer wall 3 is used to bear the static pressure of the soil layer and water. After the outer wall 3 cracks, water seeps into the partition cavity 5 from the outer wall 3. The water in the partition cavity 5 is hindered by the inner wall 4, so that the situation that water enters the inside of the basement occurs, thereby improving the waterproof performance of the basement.

[0044] Reference Figure 2 , Figure 3The bottom side of the water collecting tank 6 is provided with a drain hole 8, and the inside of the water collecting tank 6 is provided with a shielding plate 9. The shielding plate 9 is located above the drain hole 8. The top surface of the shielding plate 9 is fixedly installed with a floating block 10, and the top side of the floating block 10 is fixedly installed with a guide rod 11. The inner wall of the water collecting tank 6 is fixedly installed with a guide ring 12 for the guide rod 11 to pass through.

[0045] When the water in the water collecting tank 6 accumulates to a certain amount, the floating block 10 drives the shielding plate 9 to move upwards, thereby opening the drain hole 8, and facilitating the discharge of water in the water collecting tank 6. After the water in the water collecting tank 6 is discharged, the shielding plate 9 is lowered again to shield the drain hole 8, thereby reducing the occurrence of the case that the water in the soil layer returns to the partition cavity 5 after evaporation.

[0046] Referring to Figure 2 , Figure 3 , the top side of the water collecting tank 6 is fixedly installed with a ventilation pipe 13, and the end of the ventilation pipe 13 away from the water collecting tank 6 extends out of the ground. The end of the ventilation pipe 13 away from the water collecting tank 6 is fixedly installed with a ventilator 14. When the outer wall 3 cracks and it is not raining, the water in the soil layer will evaporate and seep into the inside of the partition cavity 5, and the water in the inside of the partition cavity 5 is less. The pipe and the ventilator 14 are used to strengthen the ventilation in the inside of the partition cavity 5, thereby facilitating the discharge of the water in the inside of the partition cavity 5 after evaporation, and thereby reducing the occurrence of the case that the water accumulates in the inside of the partition cavity 5.

[0047] Referring to Figure 2 , Figure 4 , the inner bottom wall of the partition cavity 5 is fixedly installed with a plurality of sleeves 15, and the sleeves 15 are arranged at intervals along the circumference of the floor 1. The sleeves 15 are fixedly installed with a first support plate 16, and the first support plate 16 is fixedly connected with the top surface of the floor 1. The first support plate 16 increases the connection strength between the sleeves 15 and the floor 1.

[0048] Referring to Figure 5 , Figure 6 , each sleeve 15 is provided with a support rod 19, and the rod body of the support rod 19 is provided with a sliding groove 20. The support rod 19 is a hollow structure with open ends, and the sliding groove 20 communicates with the inside of the support rod 19. One end of the support rod 19 is threadedly passed through the sleeve 15. Each support rod 19 is provided with a plurality of support blocks 21, and the support blocks 21 are semicircular.

[0049] Referring to Figure 6 , Figure 7 , the middle part of one side of the straight edge of the support plate is fixedly installed with a sliding block 22, and the sliding block 22 is slidingly arranged in the inside of the sliding groove 20. The two sides of the sliding block 22 are provided with first clamping grooves 23 for the inside walls of the sliding grooves 20 to enter. The top side of the sliding block 22 is fixedly installed with a support strip 25, and the support strip 25 is located in the inside of the sliding groove 20. The sliding openings of the same support rod 19 are separated from each other by the support strip 25. The two sides of the support strip 25 are provided with second clamping grooves 24 for the two side walls of the sliding groove 20 to enter.

[0050] The support rod 19 is screwed into the sleeve 15, and the sliding groove 20 is directed away from the outer wall 3. Then the sliding block 22 and the sliding strip are placed in the sliding groove 20, and the support block 21 is installed on the support rod 19. The support block 21 is spaced apart on the support rod 19 under the support of the support strip 25. Then the support rod 19 is continuously rotated, and the support rod 19 drives the support block 21 to tightly abut against the inner wall of the outer wall 3. The outer wall 3 is supported by the support block 21, so as to reduce the cracking of the outer wall 3. At the same time, the outer wall 3 is not extruded to extrude the inner wall 4 through the support block 21 and the support rod 19, so as to reduce the cracking of the inner wall 4.

[0051] When the support block 21 tightly abuts against the inner wall of the outer wall 3, the support block 21 pushes the sliding block 22 to move to the inside of the support rod 19, so that the inner wall of the first clamping groove 23 tightly abuts against the outer wall of the support rod 19, and the inner wall of the second clamping groove 24 tightly abuts against the inner wall of the support rod 19, thereby blocking the sliding groove 20. After the sliding groove 20 is blocked, the inside of the support rod 19 is poured with concrete, and the support block 21 and the support rod 19 are connected together through the concrete, so as to reduce the loosening of the support block 21 on the support rod 19.

[0052] Referring to Figure 7 The support block 21 is provided with at least two scraping strips 26, and the scraping strips 26 are vertically arranged. In the embodiment of the application, the scraping strips 26 are two and are respectively located on the two sides of the support rod 19. The scraping strips 26 are fixedly installed with connecting rods 27, and the support block 21 is provided with expansion holes 28 for the connecting rods 27 to pass through from the straight side to the arc side. The connecting rods 27 are fixedly installed with limiting plates 29 away from the scraping plates, and the limiting plates 29 and the straight side of the support block 21 are fixedly installed with first springs 30. The first springs 30 are sleeved on the connecting rods 27.

[0053] When the support rod 19 drives the support block 21 to tightly abut against the outer wall 3, the first spring 30 pulls the limiting plate 29 to move to the limiting block, so that the scraping strip 26 tightly abuts against the outer wall 3. The inner wall of the outer wall 3 is scraped flat by the scraping strip 26, so as to facilitate the support block 21 to abut against the inner wall of the outer wall 3.

[0054] Referring to Figure 5 , Figure 6The support rod 19 is provided with a second support plate 17 and a third support plate 18, the third support plate 18 is located below the second support plate 17. And the third support plate 18 is located above each support block 21. The second support plate 17 is fixedly connected with the bottom surface of the ceiling 2, and the second support plate 17 is provided with a through hole 32 for the support rod 19 to pass through. The support rod 19 is fixedly inserted into the ceiling 2 after passing through the second support plate 17. And the top end of the uppermost support strip 25 located on the support rod 19 is higher than the top surface of the second support plate 17. The second spring 31 is fixedly installed between the second support plate 17 and the third support plate 18, and the second spring 31 is sleeved on the support rod 19.

[0055] When laying the template for pouring the ceiling 2, the support rod 19 passes through the template. Then the second spring 31 drives the second support plate 17 to tightly abut against the bottom surface of the template, thereby reducing the leakage of concrete from the gap between the template and the support rod 19. At the same time, after the concrete solidifies into the ceiling 2, the top end of the second support plate 17 and the support rod 19 are fixedly connected with the ceiling 2, thereby reducing the situation that the outer wall body 3 extrudes the support block 21 to make the support rod 19 inclined.

[0056] The basement waterproof structure of the present application comprises the following construction steps:

[0057] The template is installed in the foundation pit for pouring the floor 1, and then the concrete is poured into the template. Then the sleeve 15 is placed in the un-solidified concrete, and the first support plate 16 abuts against the top side of the un-solidified concrete. The sleeve 15 floats on the concrete through the first support plate 16, thereby reducing the situation that the sleeve 15 sinks. After the concrete solidifies into the floor 1, the first support plate 16 is fixedly connected with the floor 1, and the sleeve 15 is also fixedly connected with the floor 1.

[0058] After the floor 1 solidifies, the template used for pouring the floor 1 is removed. Then the template for pouring the outer wall body 3 and the inner wall body 4 is installed on the top side of the floor 1, and the concrete is poured. The opening is reserved on the outer wall body 3 for installing the drain pipe 7. After the concrete solidifies, the template is removed to form the outer wall body 3 and the inner wall body 4. Then the drain pipe 7 is installed on the opening of the outer wall body 3, and the water collecting tank 6, the ventilation pipe 13 and the ventilator 14 are installed after the installation of the drain pipe 7 is completed.

[0059] After the construction of the outer wall body 3 and the inner wall body 4 is completed, the support rod 19 is screwed into the sleeve 15 part. Then the support block 21 is installed on the support rod 19, and then the support rod 19 is rotated, so that the support block 21 tightly abuts against the inner wall of the outer wall body 3.

[0060] Afterwards, the formwork is laid on the top side of the outer wall body 3 and the inner wall body 4 for pouring the ceiling 2. The formwork for pouring the ceiling 2 is provided with holes for the support rod 19 to pass through. Then the second support plate 17 is pushed against the formwork by the second spring 31, so as to reduce the leakage of concrete from the gap between the support rod 19 and the formwork. The concrete is poured into the formwork, and after the concrete solidifies to form the ceiling 2, the second support plate 17 is fixedly connected with the ceiling 2, and the top end of the support rod 19 is fixedly connected with the ceiling 2.

[0061] Compared with the prior art in which the outer wall body 3 and the inner wall body 4 are connected by the support column, the formwork for installing the outer wall body 3 and the inner wall body 4 needs to be provided with the formwork for the support column, thereby increasing the difficulty of installing the formwork for the outer wall body 3 and the inner wall body 4. When the inner wall body 4 and the outer wall body 3 need to be removed, the gap of the partition cavity 5 is small, and the support column in the prior art further hinders the removal of the formwork. In the present application, the outer wall body 3 and the inner wall body 4 are poured together, but are not connected together, thereby facilitating the installation of the formwork for pouring to form the inner wall body 4 and the outer wall body 3.

[0062] The implementation principle of the basement waterproof structure in the embodiment of the present application is that the support rod 19 is screwed into the sleeve 15, and the support rod 19 drives the support block 21 to tightly abut against the inner wall of the outer wall body 3, so as to reduce the occurrence of the cracking of the outer wall body 3 under the extrusion of the soil layer and the water static pressure, and further improve the waterproof performance of the basement. When the outer wall body 3 is extruded, the outer wall body 3 will not exert pressure on the inner wall body 4 through the support rod 19 and the support block 21, so as to reduce the occurrence of the cracking of the inner wall body 4.

[0063] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
