Description

Technical Field

[0001] The utility model belongs to the field of building anti - floating, and particularly relates to an anti - floating structure for the basement floor slab. Background Art

[0002] At present, the traditional basement anti - floating measures mainly include: increasing the self - weight of the basement for anti - floating, adding anti - floating anchor rods to the basement floor slab, and arranging anti - pulling piles. Although this method can control basement anti - floating within a certain range, there are still relatively large drawbacks. Considering the many uncertainties in the value of the anti - floating water level in the exploration, in case of continuous heavy rainfall, after being replenished by rainfall infiltration and lateral groundwater runoff, the groundwater level will rise sharply, and in the short term, it will generate a huge buoyancy force on the floor slab. Especially during the construction period, since the upper main body has not been completed and the load has not been fully loaded, in this case, the floor slab is extremely likely to crack or the whole basement floats due to the huge buoyancy force that appears in the short term. The traditional anti - floating structure has problems such as high project cost, serious waste of resources, and often a long construction period.

[0003] The Chinese utility model patent with the publication number CN205348235U discloses a new type of basement drainage anti - floating system, which includes an exterior basement wall, a drainage blind ditch, a drainage pipe, a basement floor slab, an interior basement drainage ditch, and a sump. The drainage blind ditch is opened along the outer periphery of the exterior basement wall for one week, and the drainage pipe is arranged at an appropriate height on the side wall of the exterior basement wall; the sump and the interior basement drainage ditch are opened on the basement floor slab along the inner side of the exterior basement wall, which can ensure the anti - floating effect and save costs. However, this device still has some other problems. For example, the drainage blind ditch of this device is arranged on the outer side of the exterior basement wall, and the drainage speed is relatively slow. When a heavy rain comes, the groundwater level rises rapidly, and the basement floor slab is subjected to a large buoyancy force, which is likely to cause the floor slab to crack and damage the underground structure.

[0034] As Figures 1 - 3 shown, this embodiment provides an anti-floating structure for the basement floor slab, including:

[0035] The basement floor slab body 100;

[0036] The exterior basement wall 200, configured around the basement floor slab body 100;

[0037] The water inlet hole 210, opened on the exterior basement wall 200, and the position of the water inlet hole 210 is higher than the upper surface of the basement floor slab body 100;

[0038] The flood discharge groove 110, opened on the upper surface of the basement floor slab body 100;

[0043] The adjustment assembly 160, configured on the lower surface of the fixed seat 130.

[0044] In this technical solution, in order to facilitate the adjustment of the drainage speed, a flood discharge groove 110 is provided inside the basement floor body 100. The outer basement wall 200 is fixedly arranged around the basement floor body 100, and a through water inlet hole 210 is provided on the outer basement wall 200. Through the water inlet hole 210, the groundwater outside the basement can be discharged into the basement and then flow into the flood discharge groove 110. A drainage pipe 120 is connected to the bottom plate inside the flood discharge groove 110. At the same time, a fixed seat 130 is fixedly arranged inside the flood discharge groove 110, and a drainage baffle 140 is fixedly arranged below the fixed seat 130. Through holes 150 are provided through the drainage baffle 140 and the fixed seat 130. The through holes 150 can discharge the groundwater inside the basement into the flood discharge groove 110, and then the groundwater inside the flood discharge groove 110 can be discharged from the basement through the drainage pipe 120. At the same time, an adjustment component 160 is fixedly arranged on the lower surface of the fixed seat 130, and the drainage speed can be changed.

[0045] This embodiment provides an anti-floating structure for the basement floor. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0046] As Figures 1 - 3 shown, in this embodiment, the diameter of the drainage baffle 140 is smaller than that of the fixed seat 130, and the adjustment component 160 is arranged below the fixed seat 130 and on the periphery of the drainage baffle 140.

[0047] In this technical solution, in order to facilitate the adjustment component 160 to adjust the size of the drainage hole 150, the diameter of the drainage baffle 140 is set smaller than that of the fixed seat 130. In this way, the adjustment component 160 can be fixed on the periphery of the drainage baffle 140 and on the lower surface of the fixed seat 130. In this way, when the adjustment component 160 operates, it will not affect the work of the drainage baffle 140, and at the same time, the adjustment component 160 can be closely attached to the drainage baffle 140.

[0048] This embodiment provides an anti-floating structure for the basement floor. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0049] As Figures 1 - 3 shown, in this embodiment, a filter screen 170 is fixedly arranged on the upper surface of the flood discharge groove 110.

[0050] In this technical solution, in order to prevent impurities inside the basement from blocking the drain hole 150 during drainage, a filter screen 170 is fixedly arranged on the surface of the flood discharge trough 110. The filter screen 170 is fixed on the upper surface of the basement floor body 100. In this way, when groundwater drains into the interior of the flood discharge trough 110, it can pass through the filtration of the filter screen 170, thereby reducing the risk of the drain hole 150 being blocked and enabling timely drainage.

[0051] This embodiment provides an anti-floating structure for the basement floor. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0052] As Figures 1 - 3 shown, in this embodiment, a fixing cylinder 180 is arranged between the fixing seat 130 and the drainage baffle 140. A fixing groove 181 is formed on the fixing cylinder 180, and a fixing shaft 182 is fixedly arranged inside the fixing groove 181. The fixing shaft 182 is arranged at a relatively lower position inside the fixing groove 181.

[0053] In this technical solution, in order to facilitate the cooperation with the adjusting mechanism, a fixing cylinder 180 is fixedly arranged below the middle of the drainage baffle 140. The through groove inside the fixing cylinder 180 extends to the fixing seat 130 and the drainage baffle 140. Fixing grooves 181 are formed around the fixing cylinder 180. Multiple groups of drain holes 150 are formed, and multiple fixing grooves 181 are also formed. Each group of drain holes 150 is respectively provided with a corresponding fixing groove 181. A fixing shaft 182 is fixedly arranged inside the fixing groove 181. The fixing shaft 182 is arranged at a relatively lower position inside the fixing groove 181, so as to facilitate the cooperation between the fixing cylinder 180 and the adjusting component 160.

[0054] This embodiment provides an anti-floating structure for the basement floor. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0055] As Figures 1 - 3 shown, in this embodiment, an installation hole 171 is formed in the middle of the filter screen 170. A power component 190 is arranged inside the installation hole 171 and the fixing cylinder 180. The power component 190 includes a buoyancy ball 191. A pull wire 192 is fixedly connected below the buoyancy ball 191. A limiting block 193 is fixedly arranged at the lower end of the pull wire 192, and the limiting block 193 is smaller than the fixing cylinder 180.

[0056] In the present technical solution, in order to facilitate the adjustment of the adjustment component 160 according to the size of the water flow, a through mounting hole 171 is opened in the middle of the filter screen 170, and a power component 190 is arranged inside the mounting hole 171 and the fixing cylinder 180. The buoyancy ball 191 of the power component 190 passes through the fixing seat 130 and the drainage baffle 140 and is arranged inside the flood discharge groove 110. One end of the pull wire 192 is fixedly connected to the bottom of the buoyancy ball 191, and the other end of the pull wire 192 is fixed to the bottom of the buoyancy ball 191. The limit block 193 is connected and is arranged below the fixed cylinder 180 through the pull wire 192. The diameter of the mounting hole 171 is set smaller than the diameter of the fixed cylinder 180, and the limit block 193 is set smaller than the diameter of the fixed cylinder 180 and larger than the mounting hole 171. In this way, when the buoyancy ball 191 is driven to rise by the accumulated water, the limit block 193 can be inside the flood discharge groove 110, and the height of the inside of the fixed cylinder 180 can be changed, but it will not go beyond the mounting hole 171 and disengage from the adjustment component 160.

[0057] This embodiment provides an anti-floating structure for a basement floor, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0058] like Figures 1 - 3 As shown, in this embodiment, the adjustment component 160 includes:

[0059] The rotating seat 161 is disposed on the lower surface of the fixed seat 130 and is arranged on the periphery of the drainage baffle 140;

[0060] A rotating plate 162, one end of which is rotatably connected to the rotating seat 161;

[0061] The connecting block 163 is disposed on the lower surface of the rotating plate 162, and the connecting block 163 is disposed at one end of the rotating plate 162 away from the rotating seat 161;

[0062] The connecting rope 164 has one end fixedly connected to the connecting block 163 , and the connecting rope 164 passes around the fixed shaft 182 and is connected to the limiting block 193 .

[0063] In this technical solution, in order to enable the power component 190 to control the adjustment component 160 so as to control the size of the drain hole 150, a rotating seat 161 is fixedly arranged on the lower surface of the fixed seat 130 and around the periphery of the drain baffle 140. One end of the rotating plate 162 is rotatably connected to the inside of the rotating seat 161. A connecting block 163 is fixedly arranged on the lower surface of the other end of the rotating plate 162. A connecting rope 164 is fixedly connected to the connecting block 163. The other end of the connecting rope 164 bypasses the fixed shaft 182 and is fixedly connected to the limiting block 193. In this way, when the water level in the basement rises, the buoyancy ball 191 drives the pull wire 192 to rise. Finally, the limiting block 193 is driven by the pull wire 192 to rise. Since the fixed shaft 182 limits one end of the pull wire 192, when the length of the pull wire 192 is fixed, when the limiting block 193 drives one end of the connecting rope 164 to change the height upward, the connecting rope 164 fixed on the connecting block 163 can drive the rotating plate 162 to rotate around the rotation axis. In this way, the rotating plate 162 can be separated from the drain hole 150, so as to increase the drainage rate. When the water level line drops, on the contrary, the buoyancy ball 191 drives the limiting block 193 and the pull wire 192 on the limiting block 193 to drop, so that the connecting block 163 and the connecting rope 164 fixed on the connecting block 163 rise, so as to slowly block the drain hole 150, so as to realize changing the drainage speed according to the size of the water flow rate.

[0064] This embodiment provides an anti-floating structure for the basement floor. In addition to including the technical solution of the above embodiment, it also has the following technical features.

[0065] As Figures 1 - 3 shown, in this embodiment, a counterweight 165 is arranged inside one end of the rotating plate 162 close to the fixed cylinder 180.

[0066] In this technical solution, in order to facilitate that when the water surface is not enough to reach the upper surface of the basement floor body 100, a small amount of water can also flow into the flood discharge groove 110 through the drain hole 150 and be discharged through the drain pipe 120. Therefore, a counterweight 165 is arranged on the lower surface of one end of the rotating plate 162 close to the fixed cylinder 180. The lighter counterweight 165 can slightly move one end of the rotating plate 162 away from the drain baffle 140, so that a small amount of drain holes 150 can drain the groundwater inside the basement.

[0067] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive.
