Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, and in particular relates to a temporary sealing device for post-construction pouring strips. Background Technology
[0002] In the field of building construction, post-cast strips are a construction technique used to address differential settlement between the main building and the podium of high-rise buildings, control concrete shrinkage cracks, and reduce temperature stress caused by hydration heat. Post-cast strips usually need to be poured with concrete only after the main structure is completed and the settlement is stable. During this waiting period, the post-cast strip is in an open state and faces multiple challenges. Traditional methods for temporarily sealing post-pouring strips mainly include covering them with wooden boards, plastic sheets, or building temporary retaining walls. These methods have significant drawbacks: ordinary wooden board coverings are not effective at waterproofing and are easily displaced by wind; plastic sheet coverings, while offering some waterproofing, have poor wind resistance and durability, are easily damaged, and cannot prevent construction waste from falling in; temporary retaining walls, although stable, are cumbersome to construct, generate a large amount of construction waste during demolition, increasing construction costs and time, especially during the rainy season. Rainwater entering the post-pouring strip not only soaks the foundation soil layer, affecting the quality of subsequent pouring, but may also cause steel reinforcement corrosion, reducing structural durability. In addition, if tools, materials, and various debris fall into the post-pouring strip, cleaning is difficult, increasing labor costs, delaying the construction period, and even potentially creating safety hazards. Summary of the Invention
[0003] The purpose of this invention is to provide a temporary sealing device for post-construction pouring strips to solve the problems in the prior art. The specific technical solution is as follows: A temporary sealing device for a construction post-pouring strip includes a sealing main component. The lower ends of both sides of the sealing main component are provided with elastic support seats. The two elastic support seats are respectively abutted against the ground on both sides of the post-pouring strip. The lower end of the elastic support seats is provided with a water-stop strip. The sealing main component is fixed to the steel bars in the post-pouring strip by fastening components.
[0004] Furthermore, the elastic support base is made of elastic rubber, and the waterstop strip is installed in the groove provided at the lower end of the elastic support base.
[0005] Furthermore, the waterstop strip absorbs water and expands, then adheres tightly to the ground on both sides of the post-cast strip.
[0006] Furthermore, the enclosed main body component includes a support frame, which is slidably connected to the top plate unit. Middle plate units are rotatably connected to both sides of the support frame. The middle plate units are slidably connected to the bottom plate unit. Fastening components are installed on the bottom plate unit. Elastic support seats are provided at the lower ends of both sides of the bottom plate unit. A locking unit is provided between the end of the support frame and the middle plate unit.
[0007] Furthermore, the top plate unit includes a movable block, which is slidably connected to the middle of the support frame. The lower end of the movable block is widened, and the upper end of the movable block is fixedly connected to the sealed top plate. The support frame is threadedly connected to a threaded rod, one end of which abuts against the movable block, and the other end of which is fixed with a knob.
[0008] Furthermore, the middle layer plate unit includes two rotating frames, which are rotatably connected to both sides of the support frame. The two rotating frames are fixedly connected to the inner sides of the two sealed middle layer plates, and a locking unit is provided between the ends of the two sealed middle layer plates and the ends of the support frame.
[0009] Furthermore, the base plate unit includes two sealing base plates, each of which is provided with a fastening component. The lower ends of the two sealing base plates are respectively connected to two elastic support seats. The two sealing base plates are respectively slidably connected to two sealing middle plates. The sealing base plates are provided with limiting grooves. The threaded columns provided on the sealing middle plates are slidably connected in the limiting grooves. The threaded columns are threadedly connected to a locking nut. A rubber gasket is provided between the sealing base plate and the locking nut.
[0010] Furthermore, the locking unit includes two hexagonal sliding columns, which are respectively inserted into hexagonal sliding holes at the ends of the two rotating frames. The two hexagonal sliding columns are fixedly connected to two rotating blocks. Each of the two rotating blocks is provided with positioning teeth. The two sets of positioning teeth are respectively engaged in two sets of tooth grooves at the ends of the support frame. Both rotating blocks are rotatably connected to the function plate. The lower end of the function plate is rotatably connected to the adjusting rod. The adjusting rod is rotatably connected to the lower end of the support frame. The two rotating frames are fixedly connected to two half-tooth rings, and the two half-tooth rings mesh and drive each other.
[0011] Furthermore, the upper surfaces of the sealing top plate, sealing middle plate, and sealing bottom plate are all covered with a metal skin. Baffles are provided on both sides of the sealing top plate, sealing middle plate, and sealing bottom plate. The middle part of the baffles protrudes upward. The baffles of the sealing top plate rest on the upper part of the baffles of the sealing middle plate, and the baffles of the sealing middle plate rest on the upper part of the baffles of the sealing bottom plate.
[0012] Furthermore, the fastening assembly includes a fixing bolt, which is slidably connected to the sealing base plate. A support seat is threadedly connected to the lower end of the fixing bolt. Rotary rods are rotatably connected to both sides of the support seat. Both rotating rods are engaged in the reinforcing bars in the post-cast strip. The ends of both rotating rods are bent upwards. A locking nut is threadedly connected to the upper end of the fixing bolt. A rubber gasket is provided between the upper end of the sealing base plate and the locking nut. A sealing bolt is fixed to the upper end of the fixing bolt. A sealing shell is sleeved on the outside of the sealing bolt. A rubber gasket is provided between the lower end of the sealing shell and the fixing bolt. A locking nut is threadedly connected to the sealing bolt. The lower end of the locking nut rests against the sealing shell.
[0013] The advantages of this invention are: The enclosed main component serves as the primary protective structure, spanning across the post-pouring strip. Elastic support seats at both lower ends abut against the concrete surfaces on either side of the post-pouring strip, forming a stable support. When rainwater is encountered, the waterstop strip first contacts the ground and deforms under pressure, filling uneven ground gaps. The enclosed main component is fixed to the pre-embedded reinforcing bars within the post-pouring strip via fastening components, forming a stable support structure. This effectively prevents the device from shifting under wind or external forces. The entire device forms a complete physical barrier, not only preventing rainwater from entering the post-pouring strip but also blocking tools, materials, and construction debris that may fall during construction, ensuring the cleanliness of the post-pouring strip area and providing favorable conditions for subsequent post-pouring strip construction. This avoids the additional labor costs and time delays required for cleaning up debris. Attached Figure Description

Detailed Implementation
[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0017] Example 1: As Figures 1-13 As shown, a temporary sealing device for a construction post-pouring strip includes a sealing main component 1. The lower ends of both sides of the sealing main component 1 are provided with elastic support seats 2. The two elastic support seats 2 are respectively abutted against the ground on both sides of the post-pouring strip. The lower end of the elastic support seat 2 is provided with a waterstop strip 3. The sealing main component 1 is fixed to the reinforcing steel bar 5 in the post-pouring strip by fastening components 4. The working principle of the above technical solution is as follows: The enclosed main component 1, as the main protective structure, spans across the post-pouring strip. The elastic support seats 2 at the lower ends on both sides abut against the concrete surface on both sides of the post-pouring strip, forming a stable support. When encountering rainwater, the waterstop strip 3 first contacts the ground and deforms under a certain pressure, filling the uneven ground gaps. The enclosed main component 1 is fixed to the pre-embedded steel bars 5 in the post-pouring strip by the fastening component 4, forming a stable support structure. This effectively prevents the device from shifting under the action of wind or external forces. The entire device forms a complete physical barrier, which not only prevents rainwater from entering the post-pouring strip, but also blocks tools, materials and construction waste that may fall during construction, ensuring the cleanliness of the post-pouring strip area and providing good conditions for subsequent post-pouring strip construction. This avoids the labor costs and time delays caused by debris falling in and needing to be cleaned up.
[0018] Example 2: Figures 1-13 As shown, the elastic support 2 is made of elastic rubber, and the waterstop strip 3 is installed in the groove provided at the lower end of the elastic support 2. The working principle of the above technical solution is as follows: The elastic support seat 2 is made of elastic rubber material, which has good compression deformation ability and resilience, and can adapt to ground with different flatness. When the device is placed on both sides of the post-pouring strip, the elastic support seat 2 will undergo moderate deformation under its own weight and external pressure, increasing the contact area with the ground and improving the support stability. The waterstop strip 3 is precisely installed in the specially made groove at the lower end of the elastic support seat 2. The groove design can not only ensure the accurate positioning of the waterstop strip 3, but also protect the waterstop strip 3 from damage during installation and use. The elastic support seat 2 and the waterstop strip 3 form a double sealing structure. The former provides the main support force, while the latter focuses on the waterproof function. The two work together to enable the device to maintain good sealing performance on uneven base surfaces, effectively preventing water from seeping into the post-pouring strip from the bottom.
[0019] Example 3: Figures 1-13 As shown, the waterstop strip 3 absorbs water and expands, then adheres tightly to the ground on both sides of the post-cast strip; The working principle of the above technical solution is as follows: The waterstop strip 3 is made of a special polymer material, which has the characteristic of swelling when exposed to water. When the ambient humidity increases or when it rains, the waterstop strip 3 absorbs water and gradually increases in volume. The expansion force makes it fit more tightly against the ground on both sides of the post-cast strip, especially filling the tiny gaps in uneven ground. This adaptive sealing mechanism enables the device to achieve reliable waterproofing under different base surface conditions. As the expansion process proceeds, the contact pressure between the waterstop strip 3 and the ground increases, further improving the sealing effect and forming a dynamic waterproof barrier. When the environment is dry, the waterstop strip 3 will gradually shrink and return to its original shape, facilitating the disassembly and reuse of the device. This intelligent response characteristic enables the device to maintain excellent waterproofing performance under various weather conditions, greatly extending the effective period of temporary sealing.
[0020] Example 4: Figures 1-13 As shown, the enclosed main body component 1 includes a support frame 101, which is slidably connected to the top plate unit. The middle plate unit is rotatably connected to both sides of the support frame 101. The middle plate unit is slidably connected to the bottom plate unit. The fastening component 4 is installed on the bottom plate unit. The lower ends of both sides of the bottom plate unit are provided with elastic support seats 2. A locking unit is provided between the end of the support frame 101 and the middle plate unit. The working principle of the above technical solution is as follows: The enclosed main component 1 adopts a modular design. The support frame 101 serves as the core skeleton to provide overall structural strength. The sliding connection between the top plate unit and the support frame 101 allows for vertical adjustment to adapt to different height requirements. The middle plate unit achieves angle adjustment through rotational connection, which can be unfolded to form a wide coverage or folded to reduce volume. The sliding connection between the bottom plate unit and the middle plate unit provides lateral adjustment capability, enabling the entire device to flexibly adapt to post-pouring strips of different widths. The locking unit fixes the middle plate after it is unfolded to the working position to prevent accidental rotation and ensure structural stability. This design gives the device a high degree of adaptability and flexibility. During installation, simply place the bottom plate unit on both sides of the post-pouring strip, adjust the angle of the middle plate unit, and lock the locking unit to complete the rapid deployment. Disassembly is done in reverse, rotating and merging the middle plate unit, which greatly reduces the space occupied, facilitates transportation and storage, significantly improves construction efficiency, and reduces labor intensity.
[0021] Example 5: Figures 1-13 As shown, the top plate unit includes a movable block 102, which is slidably connected to the middle of the support frame 101. The lower end of the movable block 102 is widened, and the upper end of the movable block 102 is fixedly connected to the sealing top plate 103. The support frame 101 is threadedly connected to the threaded rod 104. One end of the threaded rod 104 abuts against the movable block 102, and the other end of the threaded rod 104 is fixed with a knob 105. The middle layer plate unit includes two rotating frames 106, which are rotatably connected to both sides of the support frame 101. The two rotating frames 106 are fixedly connected to the inner side of two sealed middle layer plates 107, and a locking unit is provided between the end of the two sealed middle layer plates 107 and the end of the support frame 101. The base plate unit includes two sealing base plates 108, each of which is provided with a fastening component 4. The lower ends of the two sealing base plates 108 are respectively connected to two elastic support seats 2. The two sealing base plates 108 are respectively slidably connected to two sealing middle layer plates 107. The sealing base plate 108 is provided with a limiting groove 110. The threaded post 109 provided on the sealing middle layer plate 107 is slidably connected in the limiting groove 110. The threaded post 109 is threadedly connected to a locking nut 111. A rubber gasket 112 is provided between the sealing base plate 108 and the locking nut 111. The working principle of the above technical solution is as follows: the rotation restriction between the support frame 101 and the rotating frame 106 is released by the locking unit, and the two sealing middle plates 107 are rotated to both sides, which drives the two sealing bottom plates 108 to rotate with the two sealing middle plates 107 respectively. When the two sealing middle plates 107 rotate to a suitable angle, the rotation between the support frame 101 and the rotating frame 106 is restricted by the locking unit to ensure the overall stability. Two sealing base plates 108 are supported on the ground on both sides of the post-pouring strip by two elastic support seats 2. Pressing down on the sealing top plate 103 causes the moving block 102 to move down. The two ends of the sealing top plate 103 abut against the two sealing middle plates 107 respectively. Rotating the knob 105 causes the threaded rod 104 to move within the support frame 101. The front end of the threaded rod 104 abuts against the moving block 102 to prevent the moving block 102 and the sealing top plate 103 from moving at will. The lower end of the fastening component 4 is clamped onto the steel bar 5 in the post-pouring strip. The overall enclosed main component 1 is easy and quick to install. Rainwater can slide off from the sealing top plate 103, the sealing middle plate 107 and the sealing base plate 108 to prevent rainwater and debris from entering the post-pouring strip. Loosen the locking nut 111, and the sealing middle plate 107 and the sealing base plate 108 can slide. The threaded column 109 moves in the limiting groove 110. After adjustment, tighten the locking nut 111 to fix the sealing middle plate 107 and the sealing base plate 108, thereby changing the protection width. This design can adapt to post-pouring strips of different widths. This design greatly improves the adaptability of the device, enabling it to cope with post-pouring strips of various specifications. At the same time, it ensures the stability of the installation and the reliability of the seal, effectively preventing rainwater and debris from entering, and creating good conditions for the construction of post-pouring strips. Rotating knob 105 causes threaded rod 104 to separate from moving block 102, pulling sealing top plate 103 upward and moving moving block 102 upward. Sealing top plate 103 separates from sealing middle plate 107 to prevent sealing top plate 103 from affecting the rotation of sealing middle plate 107. The rotation restriction between support frame 101 and rotating frame 106 is released through locking unit. The two sealing middle plates 107 are rotated in the middle, causing the two sealing bottom plates 108 to rotate with the two sealing middle plates 107 respectively. After the two sealing middle plates 107 are in contact, the enclosed main body component 1 is stored, thereby reducing the overall volume of the enclosed main body component 1 and facilitating the transfer and transportation of the enclosed main body component 1.
[0022] Example 6: Figures 1-13As shown, the locking unit includes two hexagonal sliding columns 115, which are respectively inserted into the hexagonal sliding holes 114 provided at the ends of the two rotating frames 106. The two hexagonal sliding columns 115 are respectively fixedly connected to two rotating blocks 116. Each of the two rotating blocks 116 is provided with positioning teeth 117. The two sets of positioning teeth 117 are respectively engaged in the two sets of tooth grooves 113 provided at the ends of the support frame 101. Both rotating blocks 116 are rotatably connected to the function plate 118. The lower end of the function plate 118 is rotatably connected to the adjusting rod 119. The adjusting rod 119 is rotatably connected to the lower end of the support frame 101. The two rotating frames 106 are respectively fixedly connected to two half-tooth rings 120, and the two half-tooth rings 120 mesh and drive each other. The working principle of the above technical solution is as follows: The locking unit adopts a precise mechanical linkage structure. The rotation of the adjusting rod 119 drives the functional plate 118 to move horizontally, thereby controlling the engagement state of the rotating block 116 and the positioning tooth 117 with the tooth groove 113. When the positioning tooth 117 is fully engaged with the tooth groove 113, the rotating frame 106 is firmly fixed, and the entire middle plate unit remains in a stable unfolded state. When the positioning tooth 117 disengages from the tooth groove 113, the rotating frame 106 can rotate freely, facilitating angle adjustment or storage. The cooperation between the hexagonal sliding column 115 and the hexagonal sliding hole 114 ensures that the rotating block 116 can only move horizontally and cannot rotate, thus ensuring the engagement state of the positioning tooth 116. The precise meshing of the toothed rings 17 and 113, along with the meshing transmission design of the two half-toothed rings 120, ensures that the rotating frames 106 on both sides rotate synchronously, maintaining structural balance and preventing deformation or damage caused by uneven force on one side. This locking structure is easy to operate; simply rotating the adjusting rod 119 is sufficient to lock or unlock it without additional tools. The synchronous transmission mechanism ensures the coordinated movement of the middle plate units on both sides, giving the overall structure excellent stability and load-bearing capacity in the unfolded state. In the folded state, it is compact in size, making it easy to transport and store. This design significantly improves construction efficiency, reduces manpower requirements, and enhances the safety and durability of the device.
[0023] Example 7: Figures 1-13 As shown, the upper surfaces of the sealing top plate 103, the sealing middle plate 107, and the sealing bottom plate 108 are all covered with metal skins. The sealing top plate 103, the sealing middle plate 107, and the sealing bottom plate 108 are all provided with baffles 121 on both sides. The baffles 121 protrude upward in the middle. The baffles 121 of the sealing top plate 103 rest on the upper end of the baffles 121 of the sealing middle plate 107, and the baffles 121 of the sealing middle plate 107 rest on the upper end of the baffles 121 of the sealing bottom plate 108. The working principle of the above technical solution is as follows: The metal outer skin provides a robust outer layer of protection for the sealing plate, effectively resisting mechanical impacts and wear at the construction site. It also has excellent waterproof performance, preventing water from penetrating into the internal structure. The baffle plate 121 is designed with a central upward convex shape, forming an effective water guiding channel. When rainwater falls on the plate surface, it flows rapidly along the slope of the baffle plate 121 to the edge and drips off, without accumulating on the plate surface. When multiple devices are used side-by-side, the baffle plates 121 of adjacent devices overlap, with the upper baffle plate 121 covering the lower baffle plate 121. 1. Forming a tile-like layered structure, the baffle 121 bulges upward in the middle, preventing rainwater from seeping in even with tiny gaps at the overlap due to surface tension and the bulging structure. Instead, the water flows out along the bulging surface to both sides. This design creates multiple waterproof barriers, ensuring that the post-pouring strip remains dry and clean even under heavy rainfall conditions. Furthermore, the combination of the metal skin and the baffle 121 greatly extends the service life of the device, enabling it to withstand harsh construction environments, reducing replacement frequency and maintenance costs, and providing a durable and reliable temporary sealing solution for construction.
[0024] Example 8: Figures 1-13 As shown, the fastening assembly 4 includes a fixing bolt 401, which is slidably connected to the sealing base plate 108. The lower end of the fixing bolt 401 is threadedly connected to a support seat 408. Both sides of the support seat 408 are rotatably connected to rotating rods 409. Both rotating rods 409 are engaged in the reinforcing bars 5 in the post-cast strip. The ends of both rotating rods 409 are bent upwards. The upper end of the fixing bolt 401 is threadedly connected to a second locking nut 403. A second rubber gasket 402 is provided between the upper end of the sealing base plate 108 and the second locking nut 403. A sealing bolt 404 is fixed to the upper end of the fixing bolt 401. A sealing shell 406 is sleeved on the outside of the sealing bolt 404. A third rubber gasket 405 is provided between the lower end of the sealing shell 406 and the fixing bolt 401. A third locking nut 407 is threadedly connected to the sealing bolt 404. The lower end of the third locking nut 407 abuts against the sealing shell 406. The working principle of the above technical solution is as follows: The fastening component 4 achieves a firm connection with the reinforcing steel 5 in the post-pouring strip through a clever mechanical structure. The fixing bolt 401 can slide up and down to adjust its height. The support base 408 connected at the lower end has rotating rods 409 on both sides. The ends of the rotating rods 409 are bent upward to form a hook-like structure, which can be inserted into the reinforcing steel 5 at different heights in the post-pouring strip. When the locking nut 403 is tightened, the rubber gasket 402 acts as a buffer, causing the fixing bolt 401 to drive the entire closed main component 1 to press downward. At the same time, the elastic support base 2 and the waterstop strip 3 are more tightly attached to the ground, enhancing the sealing effect. The design of the sealing bolt 404 and the sealing shell 406 forms a double... A waterproof barrier, rubber gasket 405 prevents moisture from seeping in through the gap between fixing bolt 401 and enclosure 406, and locking nut 407 further tightens the seal, ensuring that the entire fastening area is completely waterproof. This structural design allows the device to adapt to steel bars 5 at different heights and positions, making installation convenient and the connection firm. Under strong winds or external forces, the device will not easily shift, maintaining a stable sealing effect. At the same time, the protective design of enclosure 406 effectively prevents rainwater from seeping in through the fasteners, solving the problem of water leakage at the connection points of traditional temporary sealing devices, greatly improving the overall waterproof reliability, and ensuring that the post-pouring strip area remains dry and clean while waiting for pouring.
