Description

Technical Field

[0001] This utility model relates to the field of seamless construction technology, and in particular to a seamless construction structure for swimming pool wall concrete. Background Technology

[0002] Seamless concrete construction is a technology that uses special processes and materials to achieve seamless connection during concrete pouring, realizing integrated construction. It can improve construction efficiency and quality, reduce waste and pollution, and is widely used in various concrete buildings. Especially during the construction of swimming pool walls, the concrete is prone to gaps due to temperature differences between the inside and outside, affecting waterproofing and structural stability. Seamless construction equipment is needed for insulation and temperature control to maintain the optimal setting temperature of the concrete to avoid gaps and ensure construction quality.

[0003] Existing seamless concrete construction equipment for swimming pool walls mostly uses fixed-size covers that cannot be adjusted in length. When dealing with long swimming pool walls, multiple covers need to be spliced ​​together: this not only increases the cost of transporting and handling the covers and the burden on manpower, but also requires each cover to be positioned and fixed individually, leading to more repetitive operations, longer construction cycles, and reduced efficiency; moreover, poor sealing at the joints of the covers allows for the leakage of hot air, resulting in localized temperature differences and uneven concrete setting, which causes cracks. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a seamless construction structure for pool wall concrete, aiming to improve the problem that the cover of existing seamless construction equipment for pool wall concrete is mostly of fixed size and cannot adjust the coverage length.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seamless construction structure for pool wall concrete, comprising a cover for wrapping the pool wall concrete formwork and concrete to form an insulated space, a hot air blower provided on one side of the cover to deliver hot air into the cover to regulate the temperature of the insulated space and prevent the concrete from solidifying and causing gaps, a controller provided on one side of the hot air blower to control the start and stop of the hot air blower and its operating parameters, a connecting plate provided on one side of the cover for fixing the cover to the concrete formwork, a handrail provided on one side of the cover to facilitate moving the cover, and an extension device provided on one side of the cover to increase the coverage length of the cover to adapt to the insulation requirements of pool wall concrete of different lengths.

A bolt for passing through the circular holes and cooperating with the threaded groove to fix the position of the concave plate is threadedly connected to the inner wall of the threaded groove. The surface size and shape of the bolt are adapted to the size and shape of the inner wall of the circular hole.

[0007] Preferably, a pull ring is fixedly connected to one side of the rectangular plate to facilitate pulling the rectangular plate to move the concave plate, and a plurality of anti-slip protrusions are fixedly connected to the inner side of the pull ring to prevent the hand from slipping.

[0008] Preferably, one end of the bolt is fixedly connected to a plurality of screw blocks that facilitate the rotation of the bolt, and the plurality of screw blocks are arranged at equal intervals.

[0009] Preferably, a rectangular hole is provided on one side of the cover, the inner wall of the rectangular hole is connected to the inner wall of the concave groove, and a circular block is fixedly connected to one side of the concave plate for sliding along the rectangular hole to prevent the concave plate from disengaging from the concave groove, and the surface of the circular block is slidably connected to the inner wall of the rectangular hole.

[0010] Preferably, one side of the cover is provided with a protective device to prevent external objects from colliding with the hot air blower and causing it to break. The protective device includes a support plate fixedly connected to the cover, a guide rod fixedly connected to one side of the support plate, a screw fixedly connected to one side of the support plate, a threaded ring threaded to the surface of the screw, a circular hole plate slidably connected to the surface of the guide rod and sleeved on the surface of the screw, the surface of the threaded ring being larger than the inner wall of the circular hole plate, and a circular frame fixedly connected to one side of the circular hole plate and sleeved on the surface of the hot air blower and controller to form a protective structure.

[0011] Preferably, the inner wall of the circular frame is fixedly connected to a filter plate for filtering the airflow entering the air inlet of the hot air blower, and the surface of the filter plate is in contact with the surface of the air inlet of the hot air blower.

[0012] Preferably, the end of the guide rod away from the support plate is fixedly connected to a limiting plate for preventing the circular hole plate from detaching from the guide rod, and the surface of the limiting plate is larger than the inner wall of the circular hole plate.

[0013] Preferably, the perforated plate and the circular frame are integrally formed, and the height of the circular frame of the protective device is not less than the total height of the hot air blower and the controller.

[0014] Preferably, the connecting seat of the extension device has a mounting hole, and the diameter of the mounting hole is the same as that of the mounting hole on the connecting plate, so as to use the same specification of screw connector.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model presents a seamless concrete construction structure for pool walls, which solves the core pain points of poor adaptability and low construction efficiency of traditional fixed-size covers in pool wall construction, while ensuring the construction goal of seamless concrete solidification. The cover used to wrap the pool wall concrete formwork and concrete can form a closed and insulated space, providing a stable temperature environment for concrete solidification; a hot air blower on one side of the cover delivers hot airflow into the insulated space, and the controller on the side can adjust the start and stop of the hot air blower and its operating parameters in real time according to different ambient temperatures, ensuring that the concrete is always in the optimal solidification temperature range, completely reducing solidification gaps caused by internal and external temperature differences, and significantly improving the structural integrity and waterproof performance of the pool wall concrete.

[0017] The connecting plate on one side of the cover firmly fixes it to the concrete formwork, preventing the cover from shifting due to vibration and collision during construction, and preventing local concrete from falling off the insulation protection and causing quality problems; the handrail provides a convenient point of leverage for moving the cover, and construction workers can easily adjust the position of the cover according to the pouring progress, greatly improving the flexibility of operation.

[0018] The extension device can increase the coverage length of the pool wall and flexibly adjust the coverage range according to the actual length of the pool wall. It eliminates the need to splice multiple devices, which reduces the workload of transporting, handling and re-installing the pool wall, lowers labor and time costs, avoids sealing gaps at the joints, and ensures that the entire pool wall concrete is in a uniform heat-insulating environment, further guaranteeing construction quality and efficiency.

[0019] 2. In this utility model, the concave groove of the extension device provides a stable sliding trajectory for the concave plate. Multiple circular holes, threaded grooves, and bolts cooperate to precisely fix the concave plate in different positions, enabling flexible adjustment of the cover length. The rectangular plate effectively expands the coverage area, and the connecting seat ensures a stable connection between the rectangular plate and the concrete formwork, allowing the extended structure to maintain reliable insulation and fixation. The pull ring provides a clear force point for pulling the rectangular plate, and the anti-slip protrusions on the inner side increase the friction between the hand and the pull ring, preventing hand slippage during pulling. Construction personnel can easily adjust the extension length without additional force, improving operational convenience. Multiple equidistant screw blocks at one end of the bolt increase the contact area between the hand and the bolt, allowing construction personnel to easily turn the bolt without tools, avoiding the difficulty of turning or hand slippage caused by the small force point of traditional bolts, and accelerating the fixing efficiency of the concave plate. The rectangular holes and circular blocks cooperate to restrict the movement trajectory of the concave plate when it slides along the concave groove, effectively preventing the concave plate from detaching from the concave groove due to uneven force, ensuring the stability of the extension device adjustment process, and avoiding construction interruption caused by component detachment.

[0020] The protective device is fixed to the cover via a support plate. A guide rod guides the sliding of the perforated plate, and a screw and screw ring lock the position of the perforated plate, ensuring the circular frame precisely fits onto the surfaces of the hot air blower and controller, forming a physical protective barrier. This intercepts external objects such as building materials and tools that may fall during construction, preventing damage to the hot air blower from impacts and ensuring the continuous and stable operation of the temperature control system. A filter plate adheres to the air inlet of the hot air blower, filtering dust, sand, and other impurities from the airflow. This prevents impurities from entering the hot air blower, clogging the air ducts, or wearing down parts, extending the lifespan of the hot air blower, and ensuring clean output airflow to prevent impurities from affecting the surface quality of the concrete. A limiting plate prevents the perforated plate from detaching when sliding along the guide rod, ensuring structural stability after assembly and preventing the perforated plate from falling off and causing protective failure.

[0021] The integrated molding structure of the perforated plate and the circular frame reduces the gap between components, enhances the structural strength of the protective device, and prevents deformation over long-term use. The height of the circular frame is no less than the total height of the hot air blower and the controller, enabling complete coverage of both and eliminating blind spots. The mounting holes of the connecting seat and the connecting plate have the same diameter, allowing the fixed rectangular plate and the fixed cover to share the same specification of screw connectors. This eliminates the need to prepare multiple specifications of accessories, reduces accessory management costs, simplifies assembly steps, and further improves construction efficiency.

Extension device 6 can flexibly adjust the coverage length, hot air blower 2 and controller 3 can maintain the optimal solidification temperature of concrete, and connecting plate 4 and handrail 5 respectively ensure the convenience of fixing and moving.

[0031] Example 2, refer to Figures 1-4Based on Embodiment 1, the extension device 6 includes a concave groove 61 formed on one side of the cover 1. A plurality of circular holes 62 are formed on one side of the cover 1, and the inner walls of the circular holes 62 are all connected to the inner wall of the concave groove 61. A concave plate 64, which can move along the concave groove 61 to adjust the extension length, is slidably connected to the inner wall of the concave groove 61. A rectangular plate 65 for expanding the coverage area of ​​the cover 1 is fixedly connected to one side of the concave plate 64. A connecting seat 66 for fixing the rectangular plate 65 to the concrete formwork is fixedly connected to one side of the rectangular plate 65. A threaded groove 67 is formed on one side of the concave plate 64, and a threaded connection is made to the inner wall of the threaded groove 67 for passing through the circular holes 62 and threaded... The groove 67 is used to fix the position of the concave plate 64 with the bolt 68. The surface size and shape of the bolt 68 are adapted to the size and shape of the inner wall of the circular hole 62. In the extension device 6, the concave plate 64 slides along the concave groove 61 to adjust the extension length. The bolt 68 passes through the circular hole 62 and is screwed into the threaded groove 67 to fix the concave plate 64. The rectangular plate 65 expands the coverage area of ​​the cover 1. The connecting seat 66 fixes the rectangular plate 65. It can flexibly adapt to the coverage requirements of the cover 1 and ensure the stability of the structure after extension. The concave groove 61 provides a stable sliding trajectory for the concave plate 64. The bolt 68 cooperates with the circular hole 62 and the threaded groove 67 to achieve precise fixation. The rectangular plate 65 and the connecting seat 66 ensure reliable coverage expansion and fixation. A pull ring 611 is fixedly connected to one side of the rectangular plate 65, facilitating the movement of the rectangular plate 65 and the concave plate 64. Multiple anti-slip protrusions are fixedly connected to the inner side of the pull ring 611 to prevent hand slippage. The pull ring 611 provides a clear point of force application, and the anti-slip protrusions on its inner side enhance the contact friction between the hand and the pull ring 611. Pulling the pull ring 611 moves the rectangular plate 65 and the concave plate 64 along the concave groove 61, easily adjusting the length of the extension device 6 and preventing hand slippage. Multiple screw blocks 69 are fixedly connected to one end of the bolt 68, facilitating the rotation of the bolt 68. These screw blocks 69 are arranged at equal intervals. The equally spaced screw blocks 69 at one end of the bolt 68 expand the contact range for hand force application, facilitating force application. When rotating the bolt 68, it can be easily screwed into the threaded groove 67 to fix the concave plate 64 without additional tools, and hand slippage is prevented. A rectangular hole 63 is provided on one side of the cover 1. The inner wall of the rectangular hole 63 is connected to the inner wall of the concave groove 61. A circular block 610 is fixedly connected to one side of the concave plate 64 for sliding along the rectangular hole 63 to prevent the concave plate 64 from dislodging from the concave groove 61. The surface of the circular block 610 is slidably connected to the inner wall of the rectangular hole 63. The sliding of the circular block 610 in the rectangular hole 63 restricts the movement trajectory of the concave plate 64 and prevents it from deviating from the concave groove 61. When the concave plate 64 slides along the concave groove 61, the circular block 610 slides synchronously with the concave plate 64 along the rectangular hole 63, which can prevent the concave plate 64 from dislodging from the concave groove 61 and ensure the stability of the adjustment process of the extension device 6.A protective device 7 is provided on one side of the cover 1 to prevent damage to the hot air blower 2 caused by collisions with external objects. The protective device 7 includes a support plate 71 fixedly connected to the cover 1. A guide rod 72 is fixedly connected to one side of the support plate 71, and a screw 74 is fixedly connected to one side of the support plate 71. A threaded ring 75 is threaded onto the surface of the screw 74. A circular hole plate 76 is slidably connected to the surface of the guide rod 72 and sleeved on the surface of the screw 74. The surface of the threaded ring 75 is larger than the inner wall of the circular hole plate 76. One side of the circular hole plate 76... A circular frame 77 is fixedly connected to the side and sleeved on the surface of the hot air blower 2 and the controller 3 to form a protective barrier. The circular frame 77 can form a physical protective barrier. The screw ring 75 and the screw 74 can securely lock the position of the circular frame 77. Pushing the circular frame 77 causes the circular plate 76 to slide along the guide rod 72 and be sleeved on the surface of the screw 74. Rotating the screw ring 75 squeezes the circular plate 76 to fix the circular frame 77. The circular frame 77 wraps around the hot air blower 2 and the controller 3, which can prevent the hot air blower 2 from being damaged by collisions with external objects and ensure the stable operation of the temperature control system.

[0032] Example 3, referring to Figures 1-4Based on Embodiment 1 or Embodiment 2, a filter plate 78 for filtering the airflow entering the air inlet of the hot air blower 2 is fixedly connected to the inner wall of the circular frame 77. The surface of the filter plate 78 is in contact with the surface of the air inlet of the hot air blower 2. The filter plate 78 can directly intercept impurities in the airflow, and the contact with the air inlet of the hot air blower 2 ensures that there is no omission in the filtration. When the hot air blower 2 is working, the filter plate 78 on the inner wall of the circular frame 77 is in contact with the air inlet of the hot air blower 2, filtering the impurities in the airflow entering the hot air blower 2. This can prevent impurities from clogging the air duct of the hot air blower 2 or wearing down the internal parts, ensuring the clean operation of the hot air blower 2 and extending its service life. The end of the guide rod 72 away from the support plate 71 is fixedly connected to a limiting plate 73 to prevent the circular hole plate 76 from detaching from the guide rod 72. The surface of the limiting plate 73 is larger than the inner wall of the circular hole plate 76. The larger surface of the limiting plate 73 can effectively intercept the sliding trajectory of the circular hole plate 76. When the circular hole plate 76 slides along the guide rod 72, the limiting plate 73 at the end of the guide rod 72 away from the support plate 71 blocks the circular hole plate 76 from continuing to move, which can prevent the circular hole plate 76 from detaching from the guide rod 72 and ensure the stable assembly of the protective device 7. The perforated plate 76 and the circular frame 77 are integrally formed. The height of the circular frame 77 of the protective device 7 is not less than the total height of the hot air blower 2 and the controller 3. The integral forming of the perforated plate 76 and the circular frame 77 reduces the connection gap to improve stability. The circular frame 77 is high enough to ensure that the components to be protected are completely covered. The height of the circular frame 77 is not less than the total height of the hot air blower 2 and the controller 3, which can fully wrap the hot air blower 2 and the controller 3 and prevent the protective device 7 from deforming, ensuring stable protection effect. The connecting seat 66 of the extension device 6 has a mounting hole, and the diameter of the mounting hole is the same as the mounting hole diameter on the connecting plate 4, so as to share the same specification of screw connectors. The same mounting hole diameter on the connecting seat 66 and the connecting plate 4 makes the connectors universal, eliminating the need to prepare screws of different specifications. When fixing the rectangular plate 65, the same specification of screw connectors can be used, reducing the types of construction accessories, reducing management costs, and simplifying assembly steps.

[0033] Working principle: During construction, the cover 1, used to wrap the pool wall concrete formwork and concrete to form an insulated space, is first moved with the help of the handrail 5, so that the cover 1 completely covers the pool wall concrete formwork and concrete. Then, the cover 1 is fixedly connected to the concrete formwork by the connecting plate 4. Next, the hot air blower 2 is started, and the hot air blower 2 delivers hot air into the cover 1 to regulate the temperature of the insulated space. The start and stop and operating parameters of the hot air blower 2 are controlled by the controller 3 to ensure that the concrete solidifies at a suitable temperature to avoid gaps. When the length of the pool wall is long and the coverage length of the cover 1 needs to be extended, the extension device 6 is operated: the rectangular plate 65 is pushed, so that the rectangular plate 65 drives the concave plate 64 to slide along the concave groove 61 on one side of the cover 1 until the concave plate 64 moves to a position that meets the coverage requirements. At this time, the threaded groove 67 on one side of the concave plate 64 is aligned with a circular hole 62 on one side of the cover 1, and the inner wall of the circular hole 62 is connected to the inner wall of the concave groove 61. The bolt 68 is passed through the circular hole 62 and screwed into the threaded groove 67. The size and shape of the bolt 68 are adapted to the size and shape of the inner wall of the circular hole 62, thereby fixing the position of the concave plate 64. Then, the rectangular plate 65 is fixed to the concrete template through the connecting seat 66 on one side of the rectangular plate 65, thus completing the expansion of the coverage length of the cover 1 to adapt to the insulation requirements of pool walls of different lengths.

[0034] To prevent damage to the hot air blower 2 from collisions with external objects, a protective device 7 is installed on one side of the cover 1. The support plate 71 of the protective device 7 is fixedly connected to the cover 1. Pushing the circular frame 77 causes the circular frame 77 to slide along the guide rod 72 on one side of the support plate 71. At the same time, the circular frame 76 moves on the surface of the screw 74 on one side of the support plate 71 until the circular frame 77 is completely fitted onto the surfaces of the hot air blower 2 and the controller 3. Then, the screw hole ring 75 on the surface of the screw 74 is rotated. The surface of the screw hole ring 75 is larger than the inner wall of the circular frame 76, causing the screw hole ring 75 to move along the surface of the screw 74 toward the circular frame 76 and press against the circular frame 76, thereby fixing the position of the circular frame 76 and the circular frame 77. The circular frame 77 forms a protective barrier for the hot air blower 2 and the controller 3. The filter plate 78 fixed to the inner wall of the circular frame 77 is in contact with the air inlet surface of the hot air blower 2. The filter plate 78 filters impurities in the airflow entering the air inlet of the hot air blower 2 to avoid blockage inside the hot air blower 2. The surface of the limiting plate 73 at the end of the guide rod 72 away from the support plate 71 is larger than the inner wall of the circular hole plate 76. The limiting plate 73 prevents the circular hole plate 76 from detaching from the guide rod 72 when it slides along the guide rod 72.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
