Description

Technical Field

[0001] The present application relates to the field of prefabricated building components, and in particular to a lifting ring for prefabricated buildings. Background Art

[0002] When making prefabricated buildings, lifting rings are often used. By installing lifting rings on the concrete model, the transportation of the manufactured prefabricated building components becomes more convenient. The lifting ring is usually U-shaped. When making the components of the prefabricated building, it is necessary to put the U-shaped open end of the lifting ring into the mold and then pour concrete into the mold. After the concrete solidifies, the two legs of the U-shaped open end of the lifting ring will be fixed in the concrete, and the U-shaped closed end of the lifting ring will be exposed to the outside, making it easier to transport the building components through the closed end of the lifting ring exposed to the outside. However, during the concrete pouring process, it is difficult to control the part of the lifting ring exposed outside the concrete. The concrete may cover the entire lifting ring or the concrete may splash onto the lifting ring and block the closed end of the lifting ring, affecting the subsequent transportation work through the lifting ring.

[0003] Reference Figure 1 In order to reduce the probability of concrete covering the lifting ring 1, a protective cover 2 is currently installed on the closed end of the lifting ring 1. The protective cover 2 is provided with a groove 21 for the closed end of the lifting ring 1 to be embedded. When in use, the closed end of the lifting ring 1 is directly inserted into the groove 21 on the protective cover 2. The closed end of the lifting ring 1 can be protected by the protective cover 2, reducing the probability of concrete blocking the closed end of the lifting ring 1.

[0004] However, when the closed end of the lifting ring is installed on the protective cover, the protective cover easily slides relative to the lifting ring when pouring concrete, causing the position of the poured concrete relative to the lifting ring to be different, resulting in different lengths of the exposed part of the lifting ring, affecting subsequent handling work. Utility Model Content

[0005] In order to reduce the relative sliding between the lifting ring and the protective cover and improve the consistency of the lifting ring exposed to the outside, the present application provides a lifting ring for assembled buildings.

[0006] The present application provides an assembled building lifting ring adopting the following technical solution:

[0007] A lifting ring for assembled buildings, comprising a lifting ring that is generally U-shaped, a protective cover that is detachably connected to the lifting ring, and a connecting assembly arranged between the lifting ring and the protective cover for fixing the position of the lifting ring on the protective cover. The cross-section of the protective cover is semicircular, and a groove for the lifting ring to be embedded is provided on the plane of the protective cover. The connecting assembly is located in the groove.

[0008] By adopting this technical solution, the protective cover is detachably connected to the lifting ring and secured by a connecting assembly. This reduces the probability of relative slippage between the lifting ring and the protective cover due to the influence of concrete during concrete pouring. The protective cover also protects the closed end of the lifting ring, reducing the probability of concrete covering the closed end or splashing onto the lifting ring, causing blockage. The semicircular cross-section of the protective cover allows the concrete pouring height to be limited during pouring, ensuring the uniformity of the exposed surface of each lifting ring.

[0009] Optionally, the connecting assembly includes two integrally arc-shaped clamping plates fixed to the bottom of the groove, the arc-shaped openings of the two clamping plates are arranged opposite to each other, and a fixed space for the lifting ring to be embedded is formed between the two clamping plates.

[0010] By adopting the above technical solution, the connecting assembly includes two integrally arc-shaped clamping plates fixed to the bottom of the groove, the arc-shaped openings of the two clamping plates are arranged opposite to each other, and a fixed space for the lifting ring to be embedded is formed between the two clamping plates, thereby achieving a stable connection between the lifting ring and the protective cover, preventing the protective cover from sliding relative to the lifting ring when pouring concrete, ensuring that the exposed part of the lifting ring is of consistent length, and improving the reliability of subsequent handling work.

[0011] Optionally, a guide plate is fixedly connected to a side of each of the clamping plates away from the bottom of the groove, and the distance between the two guide plates gradually increases from the side close to the clamping plate to the side away from the clamping plate.

[0012] By adopting the above technical solution, the design of the guide plate enables the lifting ring to be guided more smoothly when embedded in the fixed space, thereby improving the assembly efficiency between the lifting ring and the protective cover and ensuring that the lifting ring is stably fixed on the protective cover.

[0013] Optionally, a shielding member is provided at the opening of the groove for preventing external concrete from reaching the groove, and the shielding member is slidably engaged with the inner wall of the groove. A pull ring for removing the protective cover from the hanging ring is provided on the arc surface of the protective cover facing away from the groove, and the pull ring is slidably engaged with the protective cover. A transmission member is provided between the pull ring and the shielding member for driving the shielding member to slide through the movement of the pull ring.

[0014] By adopting this technical solution, the shielding member effectively prevents external concrete from entering the groove, preventing clogging of the closed end of the lifting ring. The pull ring allows the protective cover to be easily removed from the lifting ring. Simultaneously, the shielding member is driven to slide by the transmission element, enabling precise adjustment of its position and ensuring reliable protection of the closed end of the lifting ring.

[0015] Optionally, there are two shielding members, which are respectively located on opposite sides of the groove, and both sides of the groove are provided with sliding grooves for the shielding members to slide. There are also two transmission members, which are respectively arranged between the two shielding members and the two ends of the pull ring.

[0016] By adopting the above technical solution, two shielding members are provided and slide on opposite sides of the groove, and two transmission members are respectively arranged between the two shielding members and the two ends of the pull ring, which can more effectively prevent concrete from entering the groove, ensure that the closed end of the lifting ring is not blocked, and at the same time improve the stability and reliability of the shielding member action.

[0017] Optionally, the shielding member includes a shielding plate slidably connected to the sliding groove.

[0018] Optionally, the transmission member includes a screw threadedly connected to the side of the baffle plate facing the bottom of the slide groove, a gear fixed to the screw, and a rack fixed to one end of the hanging ring and meshing with the gear. An installation groove is provided in the protective cover for the rack to be embedded and slide.

[0019] By adopting the above technical solution, the baffle can slide through the transmission relationship between the screw, gear and rack, effectively preventing external concrete from entering the groove and preventing the closed end of the lifting ring from being blocked. At the same time, it ensures the stability of the position of the protective cover relative to the lifting ring, and ensures that the length of the exposed part of the lifting ring is consistent, which is convenient for subsequent handling.

[0020] Optionally, a limiting groove with a semicircular cross-section is provided on one side of the rack, and a limiting strip with a semicircular cross-section is fixed to one side of the mounting groove. When the pull ring drives the rack to slide so that the baffle is located in the slide groove, the limiting strip is embedded in the limiting groove.

[0021] By adopting the above technical solution, the limit groove opened on one side of the rack and the limit bar fixed on one side of the installation groove can enable the limit bar to be embedded in the limit groove when the pull ring drives the rack to slide so that the baffle is located in the slide groove, thereby realizing the positioning of the rack during the sliding process, avoiding the rack from shifting during the sliding process, ensuring that the opening of the groove is open under normal circumstances, and facilitating the installation and disassembly of the lifting ring.

[0022] Optionally, both ends of the U-shaped lifting ring are fixed with reinforcement pieces that increase the fixing area between the lifting ring and the concrete.

[0023] By adopting the above technical solution, the contact area between the lifting ring and the concrete is increased, the bonding strength between the lifting ring and the concrete fixed part is improved, and the load-bearing capacity and stability of the lifting ring are further improved.

[0024] Optionally, the reinforcement member includes a reinforcement rod fixed to the open end of the lifting ring, and the reinforcement rod is U-shaped as a whole.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This application provides a detachable protective cover and connecting assembly to fix the position of the lifting ring on the protective cover, thereby preventing the protective cover from sliding relative to the lifting ring during concrete pouring, ensuring the consistency of the exposed length of the lifting ring, and improving the reliability of the handling work;

[0027] 2. The clamping plate and guide plate structure in the connecting assembly can effectively fix the position of the lifting ring on the protective cover, preventing the lifting ring from being displaced due to the side pressure of the concrete, and further improving the accuracy of the lifting ring positioning;

[0028] 3. The shielding member and transmission member provided at the opening of the groove can prevent external concrete from entering the groove, thus preventing the concrete from clogging the closed end of the lifting ring and ensuring the normal use of the closed end of the lifting ring.

[0037] The following is combined with Figure 2-7 This application is described in further detail.

[0038] The embodiment of the present application discloses a lifting ring for assembled buildings. Figure 2 and Figure 3 The prefabricated building lifting ring includes a U-shaped lifting ring 1, a protective cover 2 detachably connected to the lifting ring 1, and a connecting assembly 3 disposed between the lifting ring 1 and the protective cover 2 for securing the lifting ring 1 on the protective cover 2. The protective cover 2 has a semicircular cross-section and defines a groove 21 for the lifting ring 1 to fit into. The connecting assembly 3 is located within the groove 21. The connecting assembly 3 secures the lifting ring 1 within the groove 21, thereby reducing the chance of the protective cover 2 slipping relative to the lifting ring 1 during concrete pouring, improving the stability of the lifting ring 1, and ensuring the safety and reliability of the construction project.

[0039] Both ends of the opening of the lifting ring 1 are fixed with reinforcement members 4 for increasing the fixing area between the lifting ring 1 and the concrete. The reinforcement member 4 includes a generally U-shaped reinforcement rod 41. One end of the U-shaped opening of the reinforcement rod 41 is fixed perpendicularly to the end of the lifting ring 1 to enhance the fixing effect of the lifting ring 1 in the concrete, making the fixing of the lifting ring 1 in the concrete more secure.

[0040] Reference Figure 3 and Figure 4 The connecting assembly 3 includes two clips 31 with arcuate cross-sections. The arcuate openings of the two clips 31 are arranged opposite each other, and a fixed space 33 is formed between the two clips 31 for the lifting ring 1 to be inserted. When the closed end of the lifting ring 1 is inserted into the groove 21, the closed end of the lifting ring 1 can be inserted into the fixed space 33. The two clips 31 can firmly clamp the lifting ring 1, reducing the probability of the lifting ring 1 moving within the groove 21.

[0041] In order to allow the closed end of the lifting ring 1 to slide smoothly into the fixed space 33, the connecting assembly 3 also includes a guide plate 32 fixed to the side of each clamping plate 31 away from the bottom of the groove 21. The distance between the two guide plates 32 gradually increases from the side close to the clamping plate 31 to the side away from the clamping plate 31. The guide plate 32 plays a guiding role, which helps the lifting ring 1 to be more easily embedded in the fixed space 33. The guide plate 32 can also be replaced by an inclined groove structure or a wedge-shaped guide block. The guide plate 32 and the clamping plate 31 can be formed as one piece, or they can be fixed by welding or riveting to ensure that the guide plate 32 can form a whole with the clamping plate 31.

[0042] During use, the closed end of the lifting ring 1 is directly inserted into the groove 21. The closed end of the lifting ring 1 can then follow the guide plate 32 to enter the fixed space 33, thereby fixing the position between the lifting ring 1 and the protective cover 2. After the concrete is poured, the protective cover 2 is directly pulled upward to pull the lifting ring 1 out of the fixed space 33, releasing the fixed relationship between the lifting ring 1 and the protective cover 2.

[0043] Reference Figure 4 and Figure 5 When pouring concrete, concrete may enter from the groove 21, thereby affecting the removal of the protective cover 2. Therefore, a shielding member 5 is provided for preventing external concrete from reaching the groove 21, and the shielding member 5 slides with the inner wall of the groove 21; a pull ring 6 for removing the protective cover 2 from the lifting ring 1 is provided on the arc surface of the protective cover 2 away from the groove 21, and the pull ring 6 slides with the protective cover 2; a transmission member 7 is provided between the pull ring 6 and the shielding member 5, which drives the shielding member 5 to slide through the movement of the pull ring 6, so that the shielding member 5 can be controlled to block the open end of the groove 21 to allow concrete to enter, or the shielding member 5 can be controlled to open the opening of the groove 21 to facilitate the installation and removal of the lifting ring 1.

[0044] Among them, there are sliding grooves 22 on both sides of the groove 21, two shielding members 5 are provided, and the two shielding members 5 are respectively located in the two sliding grooves 22. There are also two transmission members 7, and the two transmission members 7 are respectively connected to the two shielding members 5 and the two ends of the lifting ring 1.

[0045] Specifically, the shielding member 5 includes a shielding plate 51 slidably connected to the chute 22. When the shielding plate 51 is inserted into the chute 22, the opening of the groove 21 is opened, and the lifting ring 1 can be smoothly inserted into the groove 21 or slid out of the groove 21. When the shielding plate 51 slides out of the chute 22, the two shielding plates 51 abut against each other on the side facing away from the chute 22 to close the open end of the groove 21.

[0046] Reference Figure 4 、 Figure 5 and Figure 6The transmission member 7 includes a screw 71 threadedly connected to the bottom of the sliding groove 22 of the shielding plate, a gear 72 fixed to the screw 71, and a rack 73 fixed to the end of the pull ring 6 and meshing with the gear 72. A mounting groove 23 for the rack 73 to be embedded and slide is provided in the protective cover 2. Among them, the rack 73 can be replaced with a T-rail or a dovetail shape to enhance the tightness of its fit. Under normal circumstances, the pull ring 6 is located on the side away from the protective cover 2. At this time, both shielding plates are located in the sliding groove 22. The staff directly inserts the closed end of the lifting ring 1 into the groove 21. The closed end of the lifting ring 1 will pass through the guide plate 32 to reach the fixed space 33, which can fix the position of the lifting ring 1 in the protective cover 2. When the pull ring 6 is then slid toward the protective sleeve 2, it drives the rack 73 to slide within the mounting groove 23, causing the rack 73 to rotate the screw 71. The screw 71 then drives the shielding plate 51, which is threadedly connected to it, to slide out of the chute 22 until the two shielding plates 51 abut against each other, sealing the groove 21. As the pull ring 6 moves, it also drives the protective sleeve 2 toward the lifting ring 1, ensuring that the closed end of the lifting ring 1 is located within the fixed space 33. When the lifting ring 1 is fixed to the concrete, simply pulling the pull ring 6 upward will cause the rack 73 to slide in the opposite direction through the pull ring 6. At this time, the rack 73 also drives the screw 71 in the opposite direction via the gear 72, driving the shielding plate 51 to slide into the chute 22, thereby opening the groove 21. Once the shielding plate 51 slides into the chute 22, continuing to pull the pull ring 6 upward will cause the protective sleeve 2 to slide away from the lifting ring 1, separating the protective sleeve 2 from the lifting ring 1.

[0047] Reference Figure 5 and Figure 7 To ensure that the pull ring 6 is always located away from the protective cover 2 under normal conditions and prevent the rack 73 from sliding downward due to gravity, causing the shielding plate 51 to slide out of the chute 22, a semicircular cross-sectional limiting bar 74 is fixed to the side wall of the mounting groove 23. A limiting groove 75 for the limiting bar 74 to engage is defined on one side of the rack 73. When the pull ring 6 is located away from the protective cover 2, the limiting bar 74 also engages with the limiting groove 75, thereby fixing the shielding plate 51 in the chute 22 and ensuring that the lifting ring 1 can be smoothly inserted into the groove 21.

[0048] The design of the shielding member 5 and the transmission member 7 allows the lifting ring 1 to more effectively prevent concrete from splashing into the groove 21. When the protective cover 2 is installed in the mold of the building component, the pull ring 6 drives the rack 73 up and down, which in turn drives the gear 72 to rotate. The gear 72 drives the screw rod to rotate, causing the shielding plate 51 to slide. The shielding plate 51 slides within the chute 22 to close and open the groove 21, thereby preventing clogging of the portion of the lifting ring 1 exposed outside the concrete.

[0049] The principle of the lifting ring for prefabricated buildings according to the present application is as follows: During use, the closed end of the lifting ring 1 is directly inserted into the groove 21 and embedded in the fixed space 33. The pull ring 6 is then operated to slide toward the protective cover 2, causing the pull ring 6 to drive the rack 73 to slide within the installation groove 23. At this time, the limit bar 74 also slides out of the limit groove 75 under the action of hard force, and finally causes the two shielding plates 51 to slide out of the slide groove 22 and abut together, thereby blocking the groove 21. At this time, the open end of the lifting ring 1 can be placed in the mold of the building component, and concrete is poured into the mold of the building component until the concrete reaches the protective cover 2. After the concrete cools and solidifies, the pull ring 6 is directly operated to slide away from the protective cover 2. The pull ring 6 will drive the rack 73 to slide within the installation groove 23 and drive the shielding plate 51 to embed in the slide groove 22 until the limit bar 74 slides into the limit groove 75. As the pull ring 6 continues to slide, it will drive the protective cover 2 to slide away from the lifting ring 1, allowing the protective cover 2 to be removed from the lifting ring 1. At this point, the lifting ring 1 is fixed to the building component as a whole. Since the lifting ring 1 is fixed within the protective cover 2 via the clamping plate 31, the probability of relative sliding between the lifting ring 1 and the protective cover 2 due to the influence of the concrete during the concrete pouring process is reduced. The protective cover 2 also fixes the distance of each lifting ring 1 relative to the top of the concrete, improving the consistency of the exposed lifting ring 1. The pull ring 6 facilitates the removal of the protective cover 2 from the lifting ring 1 while also controlling the sliding of the shielding plate 51, making the operation more convenient and labor-saving.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
