[0023] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] refer to Figures 1 to 5 This utility model provides a steel beam under-concrete beam enclosure device, including a lower sealing plate 1. Several first bolt groups 2 are provided on both sides of the lower sealing plate 1. Two side sealing plates 3 are symmetrically fixedly connected above the lower sealing plate 1 via the first bolt groups 2. A first end sealing plate 4 is provided at the same end of the lower sealing plate 1 and the side sealing plates 3. A second end sealing plate 5 is provided at the end of the lower sealing plate 1 and the side sealing plates 3 away from the first end sealing plate 4. A fixing mechanism for fixing the device under the I-shaped steel beam is provided above the side sealing plates 3. The fixing mechanism includes fixing blocks 6 fixedly connected to the upper ends of the two side sealing plates 3 respectively. An mounting block 7 is fixedly connected above the fixing block 6. A sliding groove is provided in the mounting block 7. A positive threaded rod 8 is rotatably connected in the sliding groove located above one of the two side sealing plates 3, and a negative threaded rod 9 is rotatably connected in the sliding groove located on the other side sealing plate 3. Symmetrical L-shaped clamping blocks 10 are slidably connected in the sliding groove. The L-shaped clamping blocks 10 are threadedly connected to the positive threaded rod 8 and the negative threaded rod 9 respectively.

[0026] In use, the side sealing plate 3 and the lower sealing plate 1 are fixed with the first bolt group 2. Then, the first end sealing plate 4 and the second end sealing plate 5, which are set at both ends of the side sealing plate 3 and the lower sealing plate 1, are used to close the two ends of the side sealing plate 3 and the lower sealing plate 1, thereby forming a closed casting space between the side sealing plate 3, the lower sealing plate 1, the first end sealing plate 4, and the second end sealing plate 5. Then, the equipment is transported to the bottom of the I-shaped steel beam, and the L-shaped clamping block 10 is positioned above the horizontal plate below the I-shaped steel beam. In the initial state, the two opposing L-shaped clamping blocks 10 are far apart from each other. At this time, the positive thread rod 8 and the negative thread rod 9 are rotated synchronously. The L-shaped clamping blocks 10, which are threaded to the positive thread rod 8 and the negative thread rod 9, will gradually approach the vertical plate of the I-shaped steel beam from both sides, and the space between the two opposing L-shaped clamping blocks 10 is... The distance is less than the width of the horizontal plate below the I-shaped steel beam to limit the equipment from falling. At the same time, after the L-shaped clamp 10 is pressed against the vertical plate of the I-shaped steel beam, the equipment is stably fixed under the I-shaped steel beam. Then, steel bars can be installed and concrete can be poured in the pouring space. After the concrete has completely solidified, the first end sealing plate 4 and the second end sealing plate 5 can be removed first. After removing the first bolt group 2, the lower sealing plate 1 and the side sealing plate 3 can be removed in sequence. During this process, the side sealing plate 3 can directly drive the L-shaped clamp 10 to be removed from both sides of the I-shaped steel beam. Therefore, it is not necessary to reverse the positive thread rod 8 and the negative thread rod 9 at a high position to drive the L-shaped clamp 10 to reset. After the equipment is removed and placed on the ground, the positive thread rod 8 and the negative thread rod 9 can be reversed to drive the L-shaped clamp 10 to reset, and it can be used again.

[0027] This setup allows for the rapid and stable installation of the equipment using L-shaped clamps 10, positive thread rods 8, and negative thread rods 9, thereby effectively improving construction efficiency and quality and ensuring construction safety. Furthermore, by simultaneously removing L-shaped clamps 10 when removing side sealing plates 3, the dismantling process can be simplified, avoiding excessive operations by workers at heights that could increase potential risks and further ensuring construction safety.

[0028] Furthermore, the end of the positive thread rod 8 near the negative thread rod 9 extends to the outside of the mounting block 7 and is fixedly connected to a limiting sleeve 11. A flower-shaped groove is provided in the limiting sleeve 11. The end of the negative thread rod 9 near the positive thread rod 8 extends to the outside of the mounting block 7 and is fixedly connected to a flower-shaped rod 12. The flower-shaped rod 12 is slidably inserted into the flower-shaped groove.

[0029] When using the device, when installing the side sealing plate 3 onto the lower sealing plate 1 using the first bolt group 2, the flower-shaped rod 12 needs to be inserted into the flower-shaped groove first. Due to the flower-shaped structure of the flower-shaped rod 12 and the flower-shaped groove, when either the limiting sleeve 11 or the flower-shaped rod 12 rotates, the other will also rotate. Therefore, when fixing the device, only one of the positive thread rod 8 and the negative thread rod 9 needs to be rotated to synchronously drive the two opposing L-shaped clamps 10 to move closer to each other and fix the device. When removing the side sealing plate 3 and the L-shaped clamps 10, the flower-shaped rod 12 will slide out of the flower-shaped groove as the side sealing plate 3 is removed from both sides of the I-shaped steel beam, thus ensuring that the device is stably removed.

[0030] This setup allows for the synchronous driving of the positive thread rod 8 and the negative thread rod 9 using the flower-shaped rod 12, flower-shaped groove, and limiting sleeve 11 without affecting the normal assembly and disassembly of the side sealing plate 3. This further improves the ease of operation of the equipment and the fixing stability of the L-shaped clamp 10, ensuring safe and stable construction of the project.

[0031] Furthermore, a plurality of first screws 13 are fixedly connected to the end of the side sealing plate 3 and the lower sealing plate 1 near the first end sealing plate 4. The first end sealing plate 4 has a plurality of first mounting holes, and the first screws 13 are inserted into the first mounting holes. A plurality of first nuts 14 are provided on the side of the first end sealing plate 4 away from the side sealing plate 3, which are threadedly connected to the first screws 13. A plurality of threaded holes are provided on the end of the side sealing plate 3 and the lower sealing plate 1 near the second end sealing plate 5. The second end sealing plate 5 has a plurality of second mounting holes, and a second screw 15 is inserted into the second mounting hole and threadedly connected to the threaded hole.

[0032] When it is necessary to remove the first end sealing plate 4, unscrew the first nut 14 on the first screw 13, and then push the first end sealing plate 4 away from the side sealing plate 3 and the lower sealing plate 1 to remove the first end sealing plate 4. Similarly, the above operation can be reversed to assemble the first end sealing plate 4 with the lower sealing plate 1 and the side sealing plate 3. When it is necessary to disassemble or assemble the second end sealing plate 5, unscrew or screw the second screw 15 out of the threaded hole to disassemble or assemble the second end sealing plate 5.

[0033] This setup allows for the rapid disassembly and installation of the first end plate 4 and the second end plate 5 using the first screw 13, the first nut 14, and the second screw 15, thereby effectively improving the equipment's disassembly and assembly efficiency and ensuring efficient construction.

[0034] Furthermore, assembly blocks 16 are fixedly connected to both ends of the lower sealing plate 1. A third mounting hole is provided in the assembly block 16. A second bolt group 17 is provided in the third mounting hole near the second end sealing plate 5. A fourth mounting hole is provided on the fixing block 6. A third bolt group 18 is provided in the fourth mounting hole near the second end sealing plate 5.

[0035] When the construction length of a concrete beam is long, multiple sets of equipment can be prepared for assembly. The following description will take the assembly of two sets of equipment as an example, and assume that the two sets of equipment are the first set and the second set, respectively:

[0036] During the assembly process, the second end sealing plate 5 on the first device and the first end sealing plate 4 on the second device must first be removed. Then, the first screw 13 on the second device is inserted into the threaded hole on the first device, and the ends of the side sealing plates 3 and the lower sealing plate 1 of the first and second devices are respectively attached. At this time, the assembly block 16 and the fixing block 6 located near the assembly point on the first device will be attached to the assembly block 16 and the fixing block 6 located near the assembly point on the second device. Then, the two devices can be assembled by the second bolt group 17 and the third bolt group 18 set on the first device. Similarly, the above operations can be used to assemble multiple devices in sequence, thereby ensuring the stable progress of the engineering construction.

[0037] This setup allows for free assembly of the equipment using the second bolt group 17 and the third bolt group 18, effectively improving the equipment's applicability and ensuring that it can be quickly assembled according to project requirements. This further enhances the project's construction efficiency. Furthermore, by inserting the first screw 13 into the threaded hole, the assembled equipment becomes more stable, thereby effectively improving the equipment's stability and ensuring high-quality construction.

[0038] Furthermore, the ends of the positive thread rod 8 and the negative thread rod 9 that are far apart extend to the outside of the mounting block 7 and are fixedly connected to a rotating head 19.

[0039] In use, by setting the rotating head 19, the positive thread rod 8 and the negative thread rod 9 can be rotated more conveniently, thereby further improving the ease of operation of the equipment and ensuring the safety of the user.

[0040] The working principle of this utility model:

[0041] In use, the side sealing plate 3 and the lower sealing plate 1 are first fastened together using the first bolt group 2. Then, the two ends of the side sealing plate 3 and the lower sealing plate 1 are sealed by the first end sealing plate 4 and the second end sealing plate 5 installed at both ends, thus creating a closed casting area between the side sealing plate 3, the lower sealing plate 1, the first end sealing plate 4, and the second end sealing plate 5. Subsequently, the device is moved below the I-shaped steel beam, ensuring that the L-shaped clamping block 10 is positioned above the horizontal plate below the I-shaped steel beam. Initially, the two opposing L-shaped clamping blocks 10 are far apart. At this time, the positive thread rod 8 and the negative thread rod 9 are rotated synchronously, causing the L-shaped clamping blocks 10, which are threaded to the positive thread rod 8 and the negative thread rod 9, to slowly approach the vertical plate of the I-shaped steel beam from both sides. When the distance between the two opposing L-shaped clamping blocks 10 is less than that of the I-shaped steel beam... After the width of the horizontal plate below the beam is reduced, the equipment is restricted from falling. When the L-shaped clamp 10 is in close contact with the vertical plate of the I-shaped steel beam, the device will be firmly fixed under the I-shaped steel beam. Next, the reinforcing bars can be placed in the pouring area and concrete can be poured. After the concrete has completely hardened, the first end sealing plate 4 and the second end sealing plate 5 are removed first. Then, after removing the first bolt group 2, the lower sealing plate 1 and the side sealing plate 3 are removed in sequence. During this process, the side sealing plate 3 can directly drive the L-shaped clamp 10 to be removed from both sides of the I-shaped steel beam. This eliminates the need to rotate the positive thread rod 8 and the negative thread rod 9 in the opposite direction at a high position to reset the L-shaped clamp 10. After the device is removed and placed on the ground, the positive thread rod 8 and the negative thread rod 9 are rotated in the opposite direction to reset the L-shaped clamp 10. After that, it can be put into use again.
