Description

Technical Field

[0001] This application relates to the field of construction technology for ultra-long water tanks, and in particular to a rolling support for an ultra-long, seamless water tank. Background Technology

[0002] With urban development and population growth, the structural dimensions of municipal water tanks have become increasingly larger, far exceeding the limits stipulated in regulations. To prevent cracks caused by temperature stress, multiple expansion joints are required, which significantly impacts the overall performance of the tank. Furthermore, these expansion joints are often weak points, prone to leakage. Seamless water tanks have become an effective solution to this problem. Currently, ultra-long seamless water tanks typically have a sliding layer at the bottom, usually achieved by fully covering the bottom with a thin, flexible material (e.g., a two-layer felt, three-layer oil sliding layer). This reduces the coefficient of friction at the bottom, but the reduction is limited. Moreover, the flexible sliding layer is mostly made of plastic, which is easily torn or degraded over time, failing to provide long-term effectiveness. This makes it difficult to effectively control temperature stress in the long term, thus limiting the length of seamless water tanks and still making them prone to cracking. Summary of the Invention

[0003] In order to further increase the length of the water tank without setting expansion joints, while reducing the cracks generated in the water tank, this application provides a rolling support for an ultra-long, seamless water tank.

[0004] The construction method for an ultra-long seamless water tank provided in this application adopts the following technical solution: A construction method for an ultra-long, seamless water tank includes the following steps: S1. Construct several foundation bases, with the foundation bases set along the length of the pool. S2. Pour the foundation layer, and make sure the top surface of the foundation layer is at the same elevation as the top surface of the foundation base; S3. Install a rolling support on the base base. The fixed part of the rolling support is fixed on the base base, and the moving part of the rolling support is set to move along the length of the pool. S4. A plastic sheet is laid on the pad, and the support part of the rolling bearing and the plastic sheet are used as the bottom template of the pool. S5. Pouring water into the pool.

[0005] By adopting the above technical solution, the rolling bearing acts as a template, supports the upper structure, and transmits force. When the concrete cools and shrinks, the shrinkage at the bottom of the pool causes the moving part of the rolling bearing to move along the shrinkage direction of the concrete. Since the main tensile stress direction of the ultra-long pool is the length direction of the pool, the tensile stress in other directions can be ignored. Therefore, by setting the moving part of the rolling bearing to move along the length direction of the pool, the foundation constraint force (friction) on the bottom of the pool can be reduced, thereby reducing the tensile stress on the bottom of the pool and thus reducing the generation of cracks. Furthermore, the plastic sheet only serves as a template and does not bear load, thus concentrating the load on the sliding support. The foundation constraint force on the bottom of the pool corresponding to the plastic sheet is greatly reduced. When used in conjunction with the rolling support, the tensile stress on the bottom of the pool can be further reduced. Therefore, with the basic constraint force on the bottom of the pool significantly reduced, the design length of the pool can be greatly increased, thereby improving the pool's applicability.

[0006] Optionally, in step S3, the distance between adjacent rolling supports is 5-15 meters; Step S4 also includes step S4.1, filling the space between the plastic sheet and the rolling support with waterproof sealant; The plastic sheeting is made of polystyrene board, and the waterproof sealing material is polysulfide sealant.

[0007] By adopting the above technical solutions, polysulfide sealant can reduce the seepage of groundwater from the gap between the plastic sheet and the rolling bearing into the rolling bearing, and at the same time, it can also reduce the seepage of concrete slurry from the gap between the plastic sheet and the rolling bearing into the rolling bearing.

[0008] This application also provides a rolling support for an ultra-long seamless water tank, which adopts the following technical solution: A rolling support for an ultra-long seamless water tank, applied to the aforementioned construction method for an ultra-long seamless water tank, includes a supporting base plate fixed on a foundation base. The supporting base plate is rotatably connected to several rollers, which are parallel to each other and jointly support a supporting top plate. A first vertical plate is arranged along the circumference of the supporting top plate, and a rubber pad is arranged between the first vertical plate and the supporting base plate. The rubber pad is always in a compressed state.

[0009] By adopting the above technical solution, since the rubber pad is always in a compressed state and is pressed tightly against the first vertical plate, the supporting top plate will not shake during the installation and pouring vibration process, reducing the possibility of the supporting top plate being misaligned after construction. At the same time, the rubber pad still has a deformation margin, which allows the concrete to still move the supporting top plate along the shrinkage direction of the concrete during the shrinkage process, thereby reducing the tensile stress of the concrete and reducing the occurrence of cracks. Meanwhile, the compressed rubber pad also serves as a waterproofing element, reducing the risk of groundwater seeping into the support base plate and causing roller corrosion. It also prevents the first vertical plate from squeezing against the support base plate, which could lead to deformation of the support base plate or the rollers. This improves the service life of the rolling support. Compared to traditional sliding layers, it can further reduce the probability of cracks appearing in ultra-long seamless water tanks after long-term use.

[0010] Optionally, the supporting base plate is provided with a second vertical plate around its perimeter, and a plurality of rollers are rotatably connected to two corresponding second vertical plates, with the rubber pad located between the first vertical plate and the second vertical plate.

[0011] By adopting the above technical solution, the second vertical plate has a larger contact area with the rubber pad, and the second vertical plate, together with the first vertical plate, can easily compress the rubber pad and make the compression effect of the rubber pad better.

[0012] Optionally, the supporting top plate is provided with a raised plate, and a plurality of rollers jointly support the raised plate. The rubber pad supports the supporting top plate, and the top elevation of the rubber pad is higher than the top elevation of the second vertical plate. The space between the supporting plate and the second vertical plate is filled with polysulfide sealant.

[0013] By adopting the above technical solution, the protruding plate can prevent the supporting top plate from contacting the second vertical plate, thereby avoiding friction between the supporting top plate and the second vertical plate during movement, thus reducing the constraint force on the concrete and further reducing the occurrence of concrete cracks. Meanwhile, the polysulfide sealant, combined with the rubber gasket, further enhances the waterproofing of the rolling bearing.

[0014] Optionally, the bottom elevation of the first vertical plate is higher than the top elevation of the base, and the space between the first vertical plate, the polystyrene board, and the base is filled with polysulfide sealant.

[0015] By adopting the above technical solution, the first vertical plate is prevented from contacting the foundation base, thereby avoiding friction between the first vertical plate and the foundation base during movement, which in turn reduces the constraint force on the concrete and further reduces the occurrence of cracks in the concrete.

[0016] Optionally, the supporting top plate has an installation opening, and the supporting top plate has a supporting groove along its inner sidewall. The bottom of the protruding plate is supported on the supporting groove. The second vertical plate is detachably connected to a sealing plate along its length. The sealing plate is bolted to the supporting top plate. All the sealing plates, the supporting top plate, the rubber pad, and all the second vertical plates together enclose a sealing space. The sealing plate has at least two injection ports.

[0017] By adopting the above technical solution, when filling the space between the top support plate and the second vertical plate with polysulfide sealant, the sealing plate is first fixed to the second vertical plate, and then the protruding plate is removed from the top support plate. The top support plate is then pressed onto the rubber pad, while the first vertical plate and the second vertical plate work together to compress the rubber pad. The top support plate and the sealing plate are then tightened with bolts to further compress the rubber pad. Polysulfide sealant is then injected into one injection port. When the polysulfide sealant overflows from another injection port, the injection is complete. After the polysulfide sealant has solidified, the sealing plate is removed, and the protruding plate is reinstalled on the top support plate. The design of the sealing plate allows for a fuller injection of polysulfide sealant and, in conjunction with the top support plate, further compresses the rubber pad. It also facilitates construction and further improves the waterproof performance of the rolling bearing.

[0018] Optionally, the first vertical plate is detachably connected to the top support plate, the second vertical plate is detachably connected to the bottom support plate, the bottom support plate is connected to the foundation base via a connector, and the first vertical plate is provided with a clamping member for further compressing the rubber pad.

[0019] By adopting the above technical solution, during the transportation of the rolling support, the protruding plate can be inverted on the top support plate with the protruding blocks of the protruding plate facing upwards. Then, the top support plate is pressed onto the bottom support plate, and the first vertical plate and the second vertical plate are placed on top of the top support plate. The top support plate, the protruding plate, the first vertical plate and the second vertical plate are packaged and transported together, while the roller is packaged and transported separately. The detachable design of the first vertical plate, the second vertical plate and the protruding plate allows the four components to be rearranged and integrated, reducing the space occupied during transportation. During on-site installation, the support base plate is fixed to the foundation base with connectors. Then, the second vertical plate on one side is installed, and one end of the roller shaft is inserted into the second vertical plate on one side. Then, the other second vertical plates are installed, and the other end of the roller shaft is inserted into the second vertical plate on the same side. Then, a rubber pad is placed on the side of the second vertical plate away from the roller shaft. Next, the first vertical plate is connected to the support top plate. The support top plate and the first vertical plate are hoisted and fastened to the support base plate. Polysulfide sealant is injected into the space between the support top plate and the second vertical plate. The protruding plate is then installed, and the installation of the rolling bearing is completed.

[0020] Optionally, the connecting component includes a plurality of tensioning sleeves, each tensioning sleeve being connected to the supporting base plate with one end located inside the supporting base plate. An adjusting screw passes through the tensioning sleeve, and a tensioning part is provided at the end of the adjusting screw extending out of the supporting base plate. An adjusting nut is rotatably connected to the end of the tensioning sleeve located inside the supporting base plate, and the adjusting nut is threadedly connected to the adjusting screw. The plurality of tensioning sleeves are arranged along the same straight line. A lead screw is rotatably connected inside the supporting base plate, and an adjusting rack block is slidably connected inside the supporting base plate. The adjusting rack block is threadedly connected to the lead screw, and the length direction of the lead screw is the same as the arrangement direction of the plurality of tensioning sleeves. An adjusting gear is coaxially fixed to the adjusting nut, and the adjusting rack block engages sequentially with the plurality of adjusting gears during movement.

[0021] By adopting the above technical solution, mounting holes corresponding to the support sleeve are opened on the base. The end of the support sleeve extending out of the support plate is inserted into the mounting hole. Then, the lead screw is rotated, which drives the adjusting rack block to move. During the movement, the adjusting rack block drives several adjusting gears to rotate in sequence. The adjusting gears drive the adjusting nut to rotate. The adjusting nut drives the tensioning part of the adjusting screw to gradually extend into the support sleeve and open the support sleeve, so that the support sleeve is locked in the mounting hole, thus completing the fixation of the support base plate. Compared to other installation methods, whether using bolted connections with ear plates or welding with pre-embedded steel bars, the support is fixed on the side, which makes the support occupy more space. At the same time, the pre-embedded steel bars are prone to displacement during the construction of the foundation base, and time is still needed to correct them during installation. Furthermore, it is not convenient to lay the polystyrene board flat. Therefore, this connection method not only improves the ease of installation and fixing, but also makes the positioning of the rolling support more accurate by opening the mounting hole later. At the same time, the support base has no through holes, so groundwater will not seep into the support base through through holes and corrode the roller shaft. In addition, it can provide good construction conditions for the surrounding polystyrene boards.

[0022] Optionally, the clamping element includes a clamping plate, which is slidably disposed within the first vertical plate. The clamping plate can extend from the first vertical plate toward the roller shaft. The clamping plate is connected to a plurality of guide posts, which are slidably disposed within the first vertical plate. The clamping plate is connected to a push block, which has an insertion hole. The first vertical plate is threadedly connected to an adjusting bolt, one end of which extends into the insertion hole. The adjusting bolt is threadedly connected to the first vertical plate.

[0023] By adopting the above technical solution, rotating the adjusting bolt causes the push block to move, which in turn causes the pressing plate to squeeze the rubber pad, thereby further compressing the rubber pad.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. It can reduce the basic constraint force (friction force) on the bottom of the pool, thereby reducing the tensile stress on the bottom of the pool and thus reducing the occurrence of cracks; 2. The plastic sheet only serves as a template and does not bear load, thus concentrating the load on the sliding support. The foundation constraint force on the bottom of the pool corresponding to the plastic sheet is greatly reduced. When used in conjunction with the rolling support, the tensile stress on the bottom of the pool can be further reduced. 3. With the foundation constraint force at the bottom of the pool significantly reduced, the design length of the pool can be greatly increased, thereby improving the pool's applicability; 4. The compressed rubber pad also serves as a waterproofing element, reducing the risk of groundwater seeping into the support base plate and causing roller corrosion. It also prevents the first vertical plate from squeezing against the support base plate, which could lead to deformation of the support base plate or the rollers. This improves the service life of the rolling support. Compared to traditional sliding layers, it can further reduce the probability of cracks appearing in ultra-long seamless water tanks after long-term use. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] Embodiment 1 of this application discloses a construction method for an ultra-long, seamless water tank.

[0033] The construction method for an extra-long, seamless water tank includes the following steps: S1. Foundation excavation, construction of several reinforced concrete foundation bases 1, several foundation bases 1 are arranged at equal intervals along the length of the pool, and the top surface elevation of the reinforced concrete foundation bases 1 is higher than the soil layer elevation. S2. Pour the foundation layer 2, and the top surface elevation of the foundation layer 2 is the same as the top surface elevation of the foundation base 1; S3. Install a rolling support on each base 1. The fixed part of the rolling support is fixed on the base 1, and the moving part of the rolling support is set to move along the length of the pool. The distance between adjacent rolling supports is 10 meters. S4. Polystyrene board 3 is laid on the pad 2. The polystyrene board 3 around the rolling support is partially laid on the reinforced concrete foundation base 1. The top surface elevation of the polystyrene board 3 is flush with the top surface elevation of the rolling support. The support part of the rolling support and the polystyrene board 3 are used as the bottom template of the pool. S4.1, fill the space between the polystyrene board 3 and the rolling support with polysulfide sealant 4; S5. Construct the concrete base slab and water tank in sequence.

[0034] In this embodiment, the seamless water tank is poured in one direct pour. In other embodiments, the seamless water tank can be poured using a skip-pour method or by applying prestress to the steel reinforcement of the water tank before pouring.

[0035] The rolling bearing serves as a template, supporting the superstructure and transferring forces. When the concrete cools and shrinks, the shrinkage at the bottom of the pool causes the moving part of the rolling bearing to move along the shrinkage direction of the concrete. Since the main tensile stress direction of the ultra-long pool is the length direction of the pool, the tensile stress in other directions can be ignored. Therefore, by setting the moving part of the rolling bearing to move along the length direction of the pool, the foundation constraint force (friction) on the bottom of the pool can be reduced, thereby reducing the tensile stress on the bottom of the pool and thus reducing the generation of cracks, thereby achieving the goal of ultra-long pools without cracks. Furthermore, the plastic sheet only serves as a template and does not bear load, thus concentrating the load on the sliding support. The foundation constraint force on the bottom of the pool corresponding to the plastic sheet is greatly reduced. When used in conjunction with the rolling support, the tensile stress on the bottom of the pool can be further reduced. Compared to existing methods, the coefficient of friction can be reduced to over 90%. With a significant reduction in the basic constraint force at the bottom of the pool, the design length of the pool can be greatly increased, thereby improving the pool's applicability.

[0036] like Figure 1 and Figure 2 Embodiment 1 of this application also provides a rolling support for an ultra-long seamless water tank, which is applied to the construction method of the ultra-long seamless water tank in Embodiment 1. It includes a supporting base plate 5, which is a square plate. The supporting base plate 5 has a second vertical plate 51 integrally formed along its circumference. Two corresponding second vertical plates 51 are rotatably connected to a roller 6. The rotatable connection between the second vertical plate 51 and the roller 6 is as follows: through holes are opened on the second vertical plate 51. The roller 6 is a variable diameter shaft. The radii at both ends of the roller 6 are smaller than the radius of the middle section of the roller 6. The two ends of the roller 6 are respectively inserted into the corresponding through holes and adapted to the through holes. Several rollers 6 are parallel to each other. A rubber pad 7 is attached to the side of the second vertical plate 51 away from the roller shaft 6. The rubber pad 7 surrounds all the second vertical plates 51. A supporting top plate 8 is supported on the rubber pad 7. A first vertical plate 81 is integrally formed along the circumference of the supporting top plate 8. The supporting top plate 8 is a square plate. The size of the supporting top plate 8 is larger than the size of the supporting bottom plate 5. The first vertical plate 81 and the second vertical plate 51 together press the rubber pad 7 and keep the rubber pad 7 in a compressed state. The supporting bottom plate 5 is placed on the reinforced concrete foundation base 1. The supporting bottom plate 5 is welded and fixed to the pre-embedded steel bars of the reinforced concrete foundation base 1. The bottom surface elevation of the first vertical plate 81 is higher than the bottom surface elevation of the supporting bottom plate 5. The supporting base plate 5 has a raised plate 82 integrally formed on the side facing the roller 6. Several rollers 6 jointly support the raised plate 82. The top surface of the rubber pad 7 is in contact with the bottom surface of the supporting top plate 8. There is a space between the second vertical plate 51 and the supporting base plate 5. Polysulfide sealant 4 is injected into the space between the second vertical plate 51 and the supporting base plate 5.

[0037] When installing the rolling support, the support base plate 5 is first welded to the pre-embedded steel bars of the reinforced concrete foundation base 1. The central axis of the roller 6 is perpendicular to the length direction of the pool. Polysulfide sealant 4 is injected between the first vertical plate 81 and the polystyrene board 3, and between the first vertical plate 81 and the reinforced concrete foundation base 1. When pouring the water tank, the supporting top plate 8 and polystyrene board 3 are used as the bottom formwork for the concrete base slab. Reinforcing bars are welded and anchored into the supporting top plate 8. The concrete base slab is poured on the bottom formwork. After the concrete base slab reaches the required strength, the water tank is poured.

[0038] Since the rubber pad 7 is always in a compressed state, the rubber pad 7 is pressed against the first vertical plate 81, and the supporting top plate 8 will not shake during the installation and pouring vibration process, reducing the possibility of the supporting top plate 8 being misaligned after construction. Meanwhile, the rubber pad 7 still has room for deformation, allowing the concrete to still move the supporting top plate 8 along the direction of concrete shrinkage during the shrinkage process, thereby reducing the tensile stress of the concrete and reducing the occurrence of cracks. The compressed rubber pad 7 also serves as a waterproofing element, reducing the infiltration of groundwater into the support base plate 5 and preventing corrosion of the roller 6. Furthermore, it prevents the first vertical plate 81 from being squeezed against the support base plate 5, thus avoiding deformation of the support base plate 5 or the roller from being squeezed and deformed. This improves the service life of the rolling support. Compared to traditional sliding layers, it can further reduce the probability of cracks appearing in ultra-long seamless water tanks after long-term use. The protruding plate 82 can prevent the supporting top plate 8 from contacting the second vertical plate 51 and the first vertical plate 81 from contacting the foundation base 1, thereby preventing the supporting top plate 8 from generating friction with the second vertical plate 51 during movement and the first vertical plate 81 from generating friction with the foundation base 1 during movement, thus reducing the constraint force on the concrete and further reducing the occurrence of cracks in the concrete. Polysulfide sealant 4 can reduce the seepage of groundwater into the rolling bearing from the gap between the polystyrene board 3 and the rolling bearing, and reduce the seepage of concrete grout into the rolling bearing from the gap between the polystyrene board 3 and the rolling bearing. At the same time, polysulfide sealant 4, together with rubber pad 7, improves the waterproofing of the rolling bearing as a whole, reduces the corrosion of the roller 6, and helps to further improve the service life of the rolling bearing.

[0039] The implementation principle of Embodiment 1 of this application is as follows: the rolling support acts as a template, supports the upper structure and transmits force. When the concrete cools and shrinks, the shrinkage at the bottom of the pool causes the moving part of the rolling support to move along the shrinkage direction of the concrete. Since the main tensile stress direction of the ultra-long pool is the length direction of the pool, the tensile stress in other directions can be ignored. Therefore, by setting the moving part of the rolling support to move along the length direction of the pool, the foundation constraint force (friction) on the bottom of the pool can be reduced, thereby reducing the tensile stress on the bottom of the pool and thus reducing the generation of cracks.

[0040] Example 2 Embodiment 2 of this application also provides a rolling support for an ultra-long, seamless water tank.

[0041] like Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 is that the supporting top plate 8 has an installation port 83, and the installation port 83 has a supporting groove 84 along its side wall. The longitudinal section of the supporting groove 84 is L-shaped. The protruding plate 82 is supported on the supporting groove 84. The protruding plate 82 is connected to the supporting top plate 8 with countersunk bolts. The first vertical plate 81 is bolted to the supporting top plate 8, and the second vertical plate 51 is also bolted to the supporting bottom plate 5. A sealing plate 52 is connected to the side of the second vertical plate 51 facing the roller shaft 6. The sealing plate 52 is arranged along the length of the second vertical plate 51 and is bolted to the bottom of the supporting top plate 8. All the sealing plates 52, the supporting top plate 8, the rubber pad 7, and all the second vertical plates 51 together form a sealing space. The sealing plate 52 has two injection ports 521, which are arranged opposite to each other. The supporting bottom plate 5 is connected to the foundation base 1 by a connector 9. The first vertical plate 81 is provided with a clamping member 85 for further compressing the rubber pad 7.

[0042] During the transportation of the rolling support, the protruding plate 82 can be inverted on the supporting top plate 8 with the protruding blocks of the protruding plate 82 facing upwards. Then, the supporting top plate 8 is pressed onto the supporting bottom plate 5, and the first vertical plate 81 and the second vertical plate 51 are placed on top of the supporting top plate 8. The supporting top plate 8, the protruding plate 82, the first vertical plate 81 and the second vertical plate 51 are packaged and transported together. The roller 6 is packaged and transported separately. The detachable design of the first vertical plate 81, the second vertical plate 51 and the protruding plate 82 allows the parts to be rearranged and integrated, reducing the space occupied during transportation. During on-site installation, the support base plate 5 is fixed to the foundation base 1 by the connector 9. Then, the second vertical plate 51 on one side is installed, one end of the roller 6 is inserted into the second vertical plate 51 on one side, and then the other second vertical plates 51 are installed, and the other end of the roller 6 is inserted into the second vertical plate 51 on the same side. Then, a rubber pad 7 is set on the side of the second vertical plate 51 away from the roller 6. Then, the first vertical plate 81 is connected to the support top plate 8. Then, the sealing plate 52 is fixed to the second vertical plate 51, and the protruding plate 82 is removed from the supporting top plate 8. The supporting top plate 8 is pressed onto the rubber pad 7, and at the same time, the first vertical plate 81 cooperates with the second vertical plate 51 to compress the rubber pad 7. Then, the supporting top plate 8 and the sealing plate 52 are tightened with bolts to further compress the rubber pad 7. Then, polysulfide sealant 4 is injected into one injection port 521. When the polysulfide sealant 4 overflows from the other injection port 521, it indicates that the injection is complete. After the polysulfide sealant 4 solidifies, the sealing plate 52 is removed, and the protruding plate 82 is installed on the supporting top plate 8. Then, the clamping part 85 is adjusted to further compress the rubber pad 7, thus completing the installation of the rolling bearing. The design of the sealing plate 52 allows for a fuller injection of polysulfide sealant 4, and, in conjunction with the supporting top plate 8, it allows for further compression of the rubber pad 7, facilitating construction and further improving the waterproof performance of the rolling bearing.

[0043] like Figure 5 The connector 9 includes several tension sleeves 91. The tension sleeves 91 are connected to the support base plate 5 and one end of the tension sleeve 91 is located inside the support base plate 5. The tension sleeves 91 are arranged along the length direction of the support base plate 5 in two rows. An adjusting screw 92 passes through the tension sleeve 91. The end of the adjusting screw 92 extending out of the support base plate 5 is provided with a tensioning part 93. The tensioning part 93 is truncated cone-shaped. An adjusting nut 94 is rotatably connected to the end of the tension sleeve 91 located inside the support base plate 5. The adjusting nut 94 is threadedly connected to the adjusting screw 92. Two lead screws 95 are rotatably connected inside the support base plate 5. The length direction of the lead screws 95 is the same as the arrangement direction of the tension sleeves 91. The two lead screws 95 correspond to the two rows of tension sleeves 91 respectively. An adjusting rack block 96 is slidably connected inside the supporting base plate 5. The adjusting rack block 96 is threadedly connected to the lead screw 95. An adjusting gear 97 is coaxially fixed to the adjusting nut 94. During the movement, the adjusting rack block 96 engages with several adjusting gears 97 in sequence.

[0044] An installation hole corresponding to the support sleeve 91 is made on the base 1. The end of the support sleeve 91 that extends out of the support plate is inserted into the installation hole. Then, the lead screw 95 is rotated. The lead screw 95 drives the adjusting rack block 96 to move. During the movement, the adjusting rack block 96 drives several adjusting gears 97 to rotate in sequence. The adjusting gears 97 drive the adjusting nut 94 to rotate. The adjusting nut 94 drives the tensioning part 93 of the adjusting screw 92 to gradually extend into the support sleeve 91 and open the support sleeve 91, so that the support sleeve 91 is locked in the installation hole, thus completing the fixation of the support base plate 5. Compared to other installation methods, whether using bolted connections with ear plates or welding with pre-embedded steel bars, the support is fixed on the side, which makes the support occupy more space. At the same time, the pre-embedded steel bars are prone to displacement during the construction of the foundation base 1, and time is still needed to correct them during installation. Furthermore, it is inconvenient to lay the polystyrene board 3 flat. Therefore, this connection method not only improves the ease of installation and fixing, but also makes the positioning of the rolling support more accurate by opening the mounting hole later. At the same time, the support base has no through holes, so groundwater will not seep into the support base through the through holes and corrode the roller 6. It can also provide good construction conditions for the surrounding polystyrene board 3.

[0045] like Figure 4The clamping member 85 includes a clamping plate 851, which is slidably disposed within the first vertical plate 81. The clamping plate 851 can extend from the first vertical plate 81 toward the roller shaft 6. The clamping plate 851 is connected to a plurality of guide posts 852, which are slidably disposed within the first vertical plate 81. The clamping plate 851 is connected to a push block 853, which has an insertion hole 854. The first vertical plate 81 is threadedly connected to an adjusting bolt 855, one end of which extends into the insertion hole 854. The adjusting bolt 855 is threadedly connected to the first vertical plate 81 and is located at the center of the first vertical plate 81.

[0046] Rotating the adjusting bolt 855 causes the push block 853 to move, which in turn causes the clamping plate 851 to press the rubber pad 7, thereby further compressing the rubber pad 7.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
