Description
Technical Field
[0001] The utility model relates to the field of post-cast strip construction, in particular to a post-cast strip supporting device. Background Art
[0002] At present, the post-cast strip mainly adopts an independent support system. When the formwork and support are removed, the post-cast strip area is not removed and the original formwork support is retained. This method can mainly avoid the structural concrete strength when it has not reached the required strength or there is a load transferred from the upper part to ensure that the post-cast strip has sufficient support. However, in the final construction of the post-cast strip, the construction joint of the post-cast strip needs to be cleaned first. At this time, the original supported formwork must be removed again before cleaning. At this time, there is a situation where the support is separated from the cast structure, causing the post-cast strip to lose support; at the same time, the settlement post-cast strip must be capped after the main body has been cast before it can be closed. As a result, when the secondary structure construction of the underground structure begins, the post-cast strip frame has not been removed. Because the post-cast strip is a full-floor support system, the frame must be destroyed or the support method must be changed for the transportation of materials and the passage of vehicles. In this process, there is also a situation where the support structure is separated from the cast structure, which is not good for the safety of the building structure, and it consumes manpower and material resources, and there are certain safety hazards.

[0006] Furthermore, a plurality of adjusting rods are threadedly connected to the support beam, and the support plate is rotatably connected to the top of the adjusting rod.
[0007] Furthermore, one end of the reinforcing rib plate is rotatably connected to the bottom of the support plate, and the other end of the reinforcing rib plate is movably connected to the side of the support beam.

[0021] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0022] See attached Figure 1 and 2 The utility model is a post-cast strip support device. The main structure includes a plurality of support columns 2 arranged below the poured layer 1. The support columns 2 generally adopt a steel pipe structure. The bottom of the support column 2 is fixed to the bottom surface of the underground structure by anchor bolts, thereby playing a supporting role. The area between adjacent poured layers 1 constitutes a post-cast strip layer 3. The sealing time of the post-cast strip layer 3 needs to be carried out after the main body is capped, and the construction cannot be too late to avoid a large difference in structural strength with the poured layer 1, and ensure the strength of the structure connected to the poured layer 1. The bottom of the poured layer 1 is provided with a main beam 4 and a secondary beam 5. The main beam 4 and the secondary beam 5 are vertically crossed to form a supporting structure at the bottom of the poured layer 1 to ensure the overall firmness of the poured layer 1. Refer to the attached Figure 4The support column 2 is arranged at the intersection of the main beam 4 and the secondary beam 5. Since the structural strength of the main beam 4 and the secondary beam 5 is obviously greater than that of other positions of the cast layer 1, the top of the support column 2 is connected to the intersection of the main beam 4 and the secondary beam 5, which can ensure sufficient support effect and support strength. Support rods 6 are welded or bolted between adjacent support columns 2. The support rods 6 are arranged in the transverse direction to connect adjacent support columns 2. A support beam 7 is provided below the cast layer 1. The support beam 7 extends along the length direction of the post-cast strip layer 3 to achieve overall support for the edge position close to the post-cast strip layer 3. The bottom of the support beam 7 is connected to multiple support rods 6 at the same time. The bottom of the support beam 7 is supported by multiple support rods 6, thereby achieving indirect support of the support beam 7 by multiple support columns 2, so that the support points of the support beam 7 are more and the support structure is better. The structure is more solid. A plurality of support plates 8 in contact with the bottom of the poured layer 1 are arranged on the support beam 7. Due to the existence of the main beam 4 and the secondary beam 5, the support beam 7 may not be able to directly contact the floor slab of the poured layer 1. Therefore, a plurality of support plates 8 are arranged on the support beam 7 to realize direct contact support for the positions other than the main beam 4 and the secondary beam 5 on the poured layer 1. The support plates 8 extend to the edge of the poured layer 1 close to the post-cast strip layer 3 to ensure that the support plates 8 effectively support the edge of the post-cast strip layer 3, avoid the end of the poured layer 1 from being suspended in the air, and ensure the firmness of the overall structure of the post-cast strip. A reinforcing rib plate 9 is arranged between the end of the support plate 8 and the support beam 7. The setting of the reinforcing rib plate 9 can further improve the force effect of the overall part of the support plate 8, realize the uniformity of the support of the support beam 7 to the plurality of support plates 8, and further improve the firmness of the supporting structure.
[0023] Preferably, see Attachment Figure 3 A plurality of adjusting rods 10 are threadedly connected to the support beam 7, and the support plate 8 is rotatably connected to the top of the adjusting rod 10 through a bearing. Such a structure can be adaptively adjusted according to the different heights of the support beam 7 and the bottom of the cast layer 1. By rotating the adjusting rod 10, the support plate 8 rotatably connected to the top can accurately contact the bottom of the cast layer 1, thereby achieving effective support for different types of post-cast strip layers 3, further improving the scope of application and the adaptability of the support structure.
[0024] Preferably, one end of the reinforcing rib plate 9 is rotatably connected to the bottom of the support plate 8 by a pin or a hinge, and the other end of the reinforcing rib plate 9 is movably connected to the side of the support beam 7, and can be specifically connected by bolts. In such a structure, when the adjusting rod 10 drives the support plate 8 to move up and down, the reinforcing rib plate 9 avoids the support beam 7 by rotation, thereby avoiding interference during the installation process. After the support plate 8 contacts the bottom of the cast layer 1, the reinforcing rib plate 9 is rotated so that its bottom contacts the side of the support beam 7, and then it is fixed with bolts, so that the overall structure is smoother during installation, further improving the convenience and efficiency of installation.
[0025] Preferably, a fixed slot plate 11 is welded or bolted on the support column 2, and the fixed slot plate 11 is a plate-like structure with a fixed slot on the top. The two ends of the support rod 6 are movably connected to the fixed slots of the fixed slot plate 11 on the adjacent support column 2, and can be specifically fixed with bolts. Such a structure makes the connection support between the two ends of the support rod 6 and the side of the support column 2 more secure, avoids tilting or shaking of the support column 2 after installation, and ensures the firmness of the support beam 7 structure at the top of the support rod 6.
[0026] Preferably, a support plate 12 is welded or integrally formed on the support column 2, and the support plate 12 is sleeved on the outside of the support column 2. The fixed slot plate 11 is welded or bolted to the support plate 12. Such a structure utilizes the support plate 12 to expand the support area of the side of the support column 2, so that the connection between the fixed slot plate 11 and the side of the support column 2 is more stable.
[0027] Preferably, see Attachment Figure 5 The support rods 6 between the multiple adjacent support columns 2 form a triangle. The triangular structure can effectively support the support beam 7 and the multiple support plates 8, while adjacent support columns 2 are not prone to misalignment or shaking, making the overall support structure more solid.
[0028] Working principle: The structure of the utility model is provided with support columns 2 on the main crossbeam 4 and the secondary crossbeam 5 at the bottom of the poured layer 1, and support rods 6 are provided between adjacent support columns 2. A support beam 7 is provided below the poured layer 1, and the bottom of the support beam 7 is connected to multiple support rods 6 at the same time. Such a structure utilizes multiple support rods 6 to achieve effective support for the support beam 7, and multiple support plates 8 are provided on the support beam 7, and the support plates 8 extend to the edge of the post-casting belt layer 3. A reinforcing rib plate 9 is provided between the bottom of the support plate 8 and the support beam 7. Such a structure utilizes multiple support plates 8 on the support beam 7 to achieve effective support for the edge of the post-casting belt layer 3, and There is no need to remove the post-cast strip layer 3 when cleaning the edge gap, which ensures effective support for the post-cast strip at all times, ensures the stability of the post-cast strip structure, and greatly reduces possible safety hazards; the support column 2 is arranged at the intersection of the main beam 4 and the secondary beam 5. This arrangement can ensure effective support for the support beam 7 while greatly reducing the number and floor space of the support columns 2 connected to the underground structure. Therefore, when vehicles or materials are transported during the construction of the underground structure, there is no need to remove the support column 2, thereby ensuring the effectiveness of the support structure, reducing the workload of the demolition construction, and making the construction of the underground structure more convenient and efficient.
