Description
Technical Field
[0001] This invention belongs to the field of building engineering structural technology, and in particular relates to a waterproof structure specifically for post-cast strips in basements. Background Technology
[0002] During the construction process, if relatively large structures such as foundation slabs, walls, and beams are all poured at once, harmful cracks will occur in various parts of them due to uneven shrinkage and settlement.
[0003] Therefore, a common approach is to break down the large structure into smaller, independent sections. This involves first casting multiple relatively independent sections, and then filling the gaps between these sections after the shrinkage and settlement stresses have become fully apparent. The filling material is typically reinforced concrete, and the resulting strip-shaped structure is known as a post-cast strip.
[0004] On the other hand, the uneven settlement phenomenon is particularly prominent in basements of building structures, so post-cast strips in basements are one of the most common types of post-cast strips.
[0005] It is important to note that a gap will form between the post-cast strip and the previously poured building structure. This gap is highly susceptible to water leakage before the post-cast strip has fully cured. Therefore, the aforementioned waterproofing structure is used to cover this gap.
[0006] For example, Chinese utility model patent with patent publication number CN216920473U and publication date of July 8, 2022, discloses a waterproof structure for a post-cast strip on a basement roof slab. The structure consists of pre-cast concrete, a post-cast concrete strip, a steel mesh, an additional waterproof layer, and a waterproof layer. A gap is formed between adjacent pre-cast concrete sections, and the post-cast concrete strip fills the gap. A construction joint is formed between the pre-cast concrete and the post-cast concrete strip. A vertical steel mesh is installed in the construction joint. An additional waterproof layer is applied to the surface of the pre-cast concrete and the post-cast concrete strip. The additional waterproof layer covers the construction joint. A waterproof layer is applied to the surface of the additional waterproof layer. The waterproof layer covers the additional waterproof layer and extends to the surface of the pre-cast concrete where no additional waterproof layer has been applied.
[0007] The waterproof structure of the post-pouring strip in this utility model patent has a thickened water-facing structure to form a guide angle flashing, which can guide water flow outward from the structural angle and increase the adhesion of the waterproof material. This prevents rainwater from falling into the basement during construction, and the accumulated water can be drained down the slope to a location away from the construction joint, ultimately achieving a better waterproof coverage effect.
[0008] However, this post-pouring strip waterproofing structure still has at least two shortcomings in actual construction and use, which are also the technical problems that this invention aims to solve:
[0009] 1. Even if the waterproof layer and soil covering structure cover a large area and can divert water to a distant location, there will still be gaps between it and the surface of the pre-poured concrete. The small amount of residual water will still seep in little by little and eventually enter the gaps of the post-poured strip, resulting in a significant reduction in the waterproofing effect.
[0010] 2. Correspondingly, the applicant of the waterproof structure also discovered the problem mentioned in point 1 above. Therefore, the shape of the first-poured concrete was designed to be inclined upward in the middle, making it difficult for residual water to penetrate and flow back. However, this is only a mitigation method, not a radical solution. Moreover, on the other hand, this will also affect the flatness of the basement floor slab, which is not worth the effort.
[0011] Therefore, in summary, there is an urgent need for a waterproof covering structure that can prevent residual water from seeping in and has a better backflow effect, for use on the post-pouring strip of the basement. Summary of the Invention
[0012] This invention provides a waterproof structure specifically for basement post-cast strips. By installing a skeleton plate unit, annular vertical plate unit, inclined plate, and rope unit on the sloping panel, and an annular groove on the cured plate, the following advantages are achieved: 1. Unavoidable backflow water at the gap between the sloping panel and the cured plate is effectively intercepted by the annular groove, preventing backflow water from reaching or entering the post-cast strip, thus ensuring the comprehensiveness and durability of the waterproofing effect; 2. The annular vertical plate unit further blocks backflow water, enhancing the strength of the waterproofing performance of the post-cast strip; 3. The sloping panel and its waterproof structure are securely installed on the annular groove; 4. The entire waterproof structure can be removed later, and the annular groove can be filled later without affecting the normal use of the basement floor.
[0013] The technical solution adopted by the present invention to solve the above problems is: a waterproof structure for basement post-pouring strips, including a sloping panel, an annular groove disposed on the upper surface of the cured panel, surrounding the post-pouring strip and covered by the sloping panel, a skeleton plate unit disposed on the sloping panel, an annular vertical plate unit disposed on the lower surface of the skeleton plate unit, supported on the bottom surface of the annular groove and used to block backflow water, an inclined plate disposed on the inner side of the annular vertical plate unit and used to clamp the annular groove, and a pull rope unit disposed on the annular vertical plate unit and used to pull down and tighten the inclined plate.
[0014] A further preferred technical solution is that the skeleton plate unit includes an annular plate disposed within the inclined plate, and a central reinforcing plate disposed on the annular plate.
[0015] A further preferred technical solution is that the skeleton plate unit further includes a protruding post disposed on the annular plate, with its lower end face exposed on the lower surface of the inclined plate, and used for installing the pull rope unit.
[0016] A further preferred technical solution is that the annular vertical plate unit includes an annular vertical plate disposed on the lower surface of the annular plate, and an opening disposed on the annular vertical plate for the passage of the pull rope unit.
[0017] A further preferred technical solution is that the annular vertical plate unit further includes an annular support plate disposed on the lower surface of the annular vertical plate, and an annular sealing plate disposed on the lower surface of the annular support plate.
[0018] A further preferred technical solution is that the rope unit includes a rope body disposed on the opening and connected at one end to the inclined plate, and a ring disposed on the other end of the rope body for fitting the protruding post.
[0019] A further preferred technical solution is that the inclined surface of the inclined panel is also provided with a vertical groove for lifting the bottom edge of the inclined panel and for monitoring the flow of water.
[0020] A further preferred technical solution is that the rope pulling unit also includes a radial column disposed on the rope body and extending beyond the bottom edge of the inclined panel through the ring, thereby twisting to disperse the silt.
[0021] A further preferred technical solution is that the length of the radial column is greater than the diameter of the opening.
[0022] A further preferred technical solution is that the number of the vertical groove, the inclined plate, and the rope unit are equal. Attached Figure Description

[0039] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
[0040] As attached Figure 1-11 As shown, a waterproof structure specifically for basement post-pouring strips includes a sloping panel 11, an annular groove 1 disposed on the upper surface of the cured plate a, surrounding the post-pouring strip b and covered by the sloping panel 11, a skeleton plate unit 2 disposed on the sloping panel 11, an annular vertical plate unit 3 disposed on the lower surface of the skeleton plate unit 2, supported on the inner bottom surface of the annular groove 1, and used to block backflow water c, an inclined plate 4 disposed on the inner side of the annular vertical plate unit 3 and used to clamp the annular groove 1, and a pull rope unit 5 disposed on the annular vertical plate unit 3 and used to pull down and tighten the inclined plate 4.
[0041] In this embodiment, the shape of the inclined panel 11 includes an upper rectangular plane, a lower rectangular plane, and four inclined planes located between the upper and lower parallel planes.
[0042] Furthermore, the entire post-pouring strip b is located within the annular groove 1, and the entire annular groove 1 is located within the contour area of the lower surface of the inclined panel 11. The inner and outer sides of the annular groove 1 are both rectangular. The unavoidable backflow water c between the inclined panel 11 and the cured plate a can only reach the post-pouring strip b after the annular groove 1 is filled, which is extremely difficult and time-consuming. Therefore, conversely, this demonstrates the comprehensive and durable waterproofing performance of this waterproof structure.
[0043] The annular vertical plate unit 3 is fixed to the lower surface of the inclined plate 11 and abuts against the bottom surface of the annular groove 1. Therefore, it can block the backflow water c accumulated in the annular groove 1, making it difficult for even the evaporation part of the backflow water c to come into contact with the post-pouring strip b. Thus, the waterproofing effect is further optimized.
[0044] Finally, the rope unit 5 works in conjunction with the inclined plate 4, so that the inclined plate 4 can clamp the inner side of the annular groove 1, ensuring that the entire "rear-mounted part" of the inclined plate 11, the skeleton plate unit 2, the annular vertical plate unit 3, the inclined plate 4 and the rope unit 5 can be stably installed on the annular groove 1.
[0045] Additional notes should be provided: 1. After the post-pouring strip b has fully cured, the aforementioned "post-installed part" can be removed, and the annular groove 1 can be filled in the end to ensure that the entire waterproof structure does not affect the normal use of the basement floor; 2. When the amount of water flowing through the inclined panel 11 is relatively large, the annular groove 1 can be periodically pumped out. The method is to first lift the bottom edge of the inclined panel 11 and then insert a pumping pipe. This method is suitable for basements such as those in aquatic product processing basements and basements attached to swimming pools.
[0046] The skeleton plate unit 2 includes an annular plate 201 disposed within the inclined plate 11, and a central reinforcing plate 202 disposed on the annular plate 201.
[0047] In this embodiment, the inclined panel 11 is made of ordinary rubber, the skeleton plate unit 2 is made of ordinary steel, the annular plate 201 is also rectangular in shape, and the number of the central reinforcing plates 202 is set to 3-10.
[0048] The skeleton plate unit 2 also includes a protruding post 203 disposed on the annular plate 201, with its lower end face exposed on the lower surface of the inclined plate 11, and used for mounting the rope unit 5.
[0049] In this embodiment, the protruding column 203 is cylindrical, and the skeleton plate unit 2 and the inclined panel 11 are integrally formed.
[0050] The annular vertical plate unit 3 includes an annular vertical plate 301 disposed on the lower surface of the annular plate 201, and an opening 302 disposed on the annular vertical plate 301 for the passage of the pull rope unit 5.
[0051] In this embodiment, the annular vertical plate 301 is also rectangular in shape, and it is fully inserted into the annular groove 1 and located at the outer ring of the post-cast strip b, thus blocking the backflow water c. When the backflow water c accumulates slightly on the outside of the annular vertical plate 301, the annular vertical plate 301 can also block the evaporation of water vapor, so that the post-cast strip b remains as dry as possible and can solidify as quickly as possible, which is very efficient.
[0052] On the other hand, the size of the opening 302 should be as small as possible to ensure that the rope unit 5 can pass through and pull the inclined plate 4, since water vapor can pass through the opening 302, which is relatively harmful.
[0053] The annular vertical plate unit 3 further includes an annular support plate 303 disposed on the lower surface of the annular vertical plate 301, and an annular sealing plate 304 disposed on the lower surface of the annular support plate 303.
[0054] In this embodiment, the annular plate 201, the central reinforcing plate 202, the annular vertical plate 301, and the annular support plate 303 are integrally formed and are all made of corrosion-resistant metal. The annular support plate 303 reduces the pressure exerted by the annular vertical plate 301 on the inner bottom surface of the annular groove 1. The annular sealing plate 304 is made of ordinary rubber, ensuring a more adequate seal and waterproof performance between the annular support plate 303 and the inner bottom surface of the annular groove 1, and minimizing the possibility of backflowing water c flowing inward past the annular vertical plate 301.
[0055] On the other hand, the annular vertical plate unit 3 also ensures that the inclined panel 11 above the annular groove 1 will not be easily crushed or deformed by passing pedestrians and vehicles.
[0056] The rope unit 5 includes a rope body 501 disposed on the opening 302 and connected at one end to the inclined plate 4, and a ring 502 disposed on the other end of the rope body 501 and used to loop the protruding post 203.
[0057] In this embodiment, during the initial installation of the "rear-mounted part", the inclined plate 4 is in the unsecured position f, at which time the inclined plate 4 is difficult to fully clamp the inner side of the annular groove 1.
[0058] Therefore, the function of the rope 501 is to appropriately pull down the inclined plate 4 so that the non-installation end of the inclined plate 4 is still tilted upward, but the upward tilt is reduced, thus fully clamping the inner side of the annular groove 1 and fully securing the entire "rear-mounted part".
[0059] Furthermore, when the "rear-mounted part" is initially installed downwards on the annular groove 1, the ring 502 is left outside the bottom edge of the inclined panel 11 to ensure that the subsequent pulling operation of the rope 501 does not require lifting the bottom edge of the inclined panel 11. Of course, when the ring 502 is placed back on the protruding post 203, it is necessary to lift the bottom edge of the inclined panel 11.
[0060] It should be noted that the waterproof structure can be used once or repeatedly. When the former method is adopted, the "re-installed part" is directly removed by breaking it. When the latter method is adopted, the "re-installed part" needs to be lifted upward. At this time, the inclined plate 4 will be tightened first and then completely loosened. Therefore, the upward lifting action requires a relatively large force.
[0061] The inclined surface of the inclined panel 11 is also provided with a vertical groove 6 for lifting the bottom edge of the inclined panel 11 and for monitoring the flow of water.
[0062] In this embodiment, the vertical groove 6 has at least the following two functions:
[0063] 1. Using the upper part and outer edge of the annular groove 1 as fulcrum, the vertical groove 6 is the position g where the bottom edge of the inclined panel is lifted. At this time, the part of the inclined panel 11 corresponding to the vertical groove 6 is appropriately concave, and the bottom edge of the inclined panel 11 can be appropriately lifted. Then, the actions of taking and putting in the ring 502 and inserting the sludge pump h can be carried out smoothly. The downward force action at the vertical groove 6 is canceled, and the bottom edge of the inclined panel 11 is reattached to the upper surface of the solidified plate a.
[0064] 2. The amount of water accumulated in the vertical trough 6 is positively correlated with the amount of water accumulated in the annular trough 1. Therefore, monitoring the amount of water in the vertical trough 6 can provide guidance and instructions on the appropriate time to use the sludge pump h, which is very convenient.
[0065] The rope unit 5 also includes a radial column 503 disposed on the rope body 501 and extending beyond the bottom edge of the inclined panel 11 via the ring 502 and then twisted to disperse the silt d.
[0066] In this embodiment, the sludge pump h is generally only used to pump out the return water c in the annular trough 1 that exceeds the preset warning value. However, in the above-mentioned use scenarios such as the basement of aquatic product processing and the basement attached to a swimming pool, the return water c will inevitably carry a large amount of impurities, eventually turning "accumulated water" into "sludge".
[0067] Therefore, before the sludge pump h is inserted into the annular groove 1, the sludge needs to be broken up; otherwise, the sludge will be difficult to remove quickly and completely. This is the action of the radial column 503.
[0068] The specific method of using the radial column 503 is as follows:
[0069] First, initially, the middle section of the rope 501 hangs down on the bottom surface of the annular groove 1. During the silt formation process, the radial column 503 is buried in the silt.
[0070] Second, after the ring 502 is taken outward in the aforementioned manner, the rope 501 is twisted appropriately so that the radial column 503 can break up the silt that is likely to have clumped at this time, and finally the sludge pumping machine can quickly and completely suck it out.
[0071] In other words, if the clumps of silt are not removed, it is equivalent to reducing the effective volume of the temporary water storage in the annular groove 1, making it easier for the return water c to cross the annular vertical plate 301 and seep into the post-cast strip b, which needs to be avoided.
[0072] The length of the radial column 503 is greater than the diameter of the opening 302.
[0073] In this embodiment, the opening 302 is positioned relatively high on the annular vertical plate 301 to prevent water from easily passing through the opening 302. All the radial columns 503 cannot pass through the opening 302, and most of the radial columns 503 hang down on the inner bottom surface of the annular groove 1, ensuring better subsequent sludge dispersal effect.
[0074] The number of the vertical groove 6, the inclined plate 4, and the rope unit 5 are equal.
[0075] In this embodiment, the vertical groove 6, the inclined plate 4, and the rope-pulling unit 5 are positioned as close as possible to each other in the left and right directions. Furthermore, if the vertical groove 6 does not sufficiently raise the bottom edge of the inclined plate 11, an external, supplementary upward tilting operation can be performed on the bottom edge of the inclined plate 11 to ensure that the ring 502 can be easily placed and removed, and that the tube of the sludge pump h can be smoothly inserted into the bottom of the annular groove 1.
[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of the present invention. These are non-inventive modifications and are protected by patent law as long as they fall within the scope of the claims of the present invention.
