Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a support device that does not require dismantling. Background Technology

[0002] During the construction of subway station ancillary works, the locations connecting to the subway station are usually reinforced concrete structures such as entrances / exits, ventilation shafts, and transfer passages. Considering the construction techniques and foundation pit support methods, the retaining structure at the connection point needs to be removed after the ancillary structure construction. The conventional approach is to remove the section to be removed in segments and use concrete structures for segmental support to ensure the stability of the foundation pit. However, this method has a significant impact on the construction period. The concrete curing period during the segmented construction after removal is long; the specifications require that the post-pouring strip construction take no less than 42 days, which significantly affects the construction progress. Therefore, it is necessary to develop a new support device that, while providing support, can also be considered as permanently placing the connection structure in the concrete, ensuring structural construction safety while saving construction time.

[0003] In a support device with application number 202421153557.4, a protective structure is set up. When the sidewall of a cave needs protection, a first baffle is bolted between two support legs, and a second baffle is installed on the first baffle through the cooperation of a protruding block and a moving groove. Since the second baffle is longer than the first baffle, when the sidewall of the cave needs to be mined, the bolts in the connecting holes on the first baffle are removed, thereby eliminating the restriction on the second baffle and making the second baffle perpendicular to the first baffle. Through the rotational cooperation of the shielding plate and the top frame, the shielding plate is rotated to be parallel to the top frame, and the limiting plate is inserted into the limiting holes on the top frame and the shielding plate, thereby exposing the side of the entire support device, which facilitates mining and the collection of metal minerals.

[0004] However, most existing support devices require disassembly after use, which can easily lead to delays in the construction period. At the same time, the disassembly process can also damage the support devices, making them unsuitable for later use. Utility Model Content

[0005] The purpose of this utility model is to provide a support device that does not require dismantling, which solves the problem that most existing support devices need to be dismantled after use, which can easily lead to an extension of the construction period. At the same time, the dismantling process can also easily damage the support device, making it inconvenient for its later use.

[0006] To achieve the above objectives, this utility model provides a non-removable support device, comprising a first steel plate, a limiting frame symmetrically fixedly installed on the bottom side of one side of the first steel plate, a first reinforcing rib fixedly installed on one side of the first steel plate corresponding to the inner position of the limiting frame, a steel pipe fixedly installed on one side of the first steel plate corresponding to the outer position of the limiting frame, a second reinforcing rib fixedly installed on one side of the first steel plate corresponding to the outer position of the steel pipe, and a connecting pipe fixedly connected to the outer edges of the two steel pipes.

[0007] Preferably, the first steel plate has symmetrically formed limiting grooves at the top center, and limiting blocks are engaged inside the limiting grooves. A second steel plate is fixedly connected to one side of the two limiting blocks, and expansion bolts are embedded and fixedly installed on the inner side of the second steel plate.

[0008] Preferably, the inner side of the steel pipe is slidably connected to the limiting frame, and the outer side of the steel pipe and the inner side of the limiting frame are both welded and fixedly connected to one side of the first steel plate.

[0009] Preferably, the two ends of the connecting pipe are welded and fixedly connected to the outer sides of the two steel pipes respectively, and the longitudinal sections of the first reinforcing rib and the second reinforcing rib are both right-angled triangles.

[0010] Preferably, the top and bottom edges of the second steel plate are welded and fixedly connected to the outer side of the first steel plate, and the connection between the second steel plate and the first steel plate forms a 90-degree angle.

[0011] Preferably, a structural plate is fixedly connected to one side of the first steel plate and the second steel plate, a nameplate is embedded and fixedly installed at the top corner of the second steel plate, and a fastening groove is provided on one side of both the first steel plate and the second steel plate.

[0012] Preferably, the outer side of the structural plate is tightly fitted to the inner side of the fastening groove, and the inner side of the structural plate is fixedly connected to the outer side of the expansion bolt.

[0013] This utility model discloses a non-removable support device. Through the cooperation of a limiting frame, a first reinforcing rib, and a second reinforcing rib, it can improve the structural connection strength between the steel pipe and the first steel plate, thereby ensuring the stability of the steel pipe during use. At the same time, through the cooperation of the limiting groove and the limiting block, it is convenient for workers to align and weld the first steel plate and the second steel plate later, reducing the difficulty for workers to splice the first steel plate and the second steel plate. Thus, the entire support device can be directly used as a reinforced concrete structure in the engineering construction process, avoiding the need for workers to disassemble the entire support device later.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 As shown, a non-removable support device includes a first steel plate 1. A limiting frame 2 is symmetrically fixedly installed on the bottom side of one side of the first steel plate 1. A first reinforcing rib 3 is fixedly installed on the side of the first steel plate 1 at a position corresponding to the inner side of the limiting frame 2. A steel pipe 4 is fixedly installed on the side of the first steel plate 1 at a position corresponding to the outer side of the limiting frame 2. The inner side of the steel pipe 4 is slidably connected to the limiting frame 2, which can limit the movement direction of the steel pipe 4 and also support the steel pipe 4 after it has moved, reducing the difficulty for workers to weld the steel pipe 4 later. The outer edge of the steel pipe 4 and the inner edge of the limiting frame 2 are both connected to the first steel plate 1. The steel pipe 4 and the limiting frame 2 are fixedly welded on one side of the plate 1 to ensure the stability of the steel pipe 4 and the limiting frame 2 during use and to prevent the steel pipe 4 and the limiting frame 2 from separating from the first steel plate 1. A second reinforcing rib 5 is fixedly installed on one side of the first steel plate 1 at the position corresponding to the outer side of the steel pipe 4. The longitudinal section of the first reinforcing rib 3 and the second reinforcing rib 5 are both right-angled triangles. A connecting pipe 6 is fixedly connected to the outer side of the two steel pipes 4. The two ends of the connecting pipe 6 are welded and fixedly connected to the outer side of the two steel pipes 4 respectively, which can fix the other end of the two steel pipes 4 and improve the structural strength between the two steel pipes 4.

[0022] The top center of the first steel plate 1 is symmetrically provided with limiting grooves 7, and limiting blocks 8 are engaged inside the limiting grooves 7. The two limiting blocks 8 are fixedly connected to one side of the second steel plate 9, which facilitates the workers to limit the position of the second steel plate 9 during the subsequent welding process and avoids the phenomenon of the second steel plate 9 shifting position. The top edge and bottom edge of the second steel plate 9 are welded and fixedly connected to the outer side of the first steel plate 1. The connection between the second steel plate 9 and the first steel plate 1 forms a 90-degree angle, which can fix the second steel plate 9 and the first steel plate 1, ensuring the structural strength of the second steel plate 9 and the first steel plate 1 during use. Expansion bolts 10 are embedded and fixedly installed on the inner edge of the second steel plate 9. The expansion bolts 10 are of type M20x250.

[0023] A structural plate 11 is fixedly connected to one side of the first steel plate 1 and the second steel plate 9. The inner side of the structural plate 11 is fixedly connected to the outer side of the expansion bolt 10, which enables the second steel plate 9 to be fixedly connected to the structural plate 11. A nameplate 12 is embedded and fixedly installed at the top corner of the second steel plate 9. A fastening groove 13 is opened on one side of both the first steel plate 1 and the second steel plate 9. The outer side of the structural plate 11 is tightly fitted to the inner side of the fastening groove 13, which can enhance the structural strength of the connection between the first steel plate 1, the second steel plate 9 and the structural plate 11.

[0024] The worker moves the limiting frame 2 until one side of the limiting frame 2 contacts the outer side of the first steel plate 1. After the limiting frame 2 is placed in the appropriate position, the worker welds the inner side of the limiting frame 2 where it contacts the first steel plate 1. Simultaneously, the first reinforcing rib 3 is welded to the connection points of the first steel plate 1 and the limiting frame 2 to ensure the stability of the limiting frame 2 during use. Then, the worker moves the steel pipe 4, which slides between its inner side and the outer side of the limiting frame 2, thus limiting the direction of movement of the steel pipe 4. When one end of the steel pipe 4 contacts one side of the first steel plate 1... When touched, the movement position of the steel pipe 4 can be limited. After the steel pipe 4 moves to the appropriate position, the worker welds the connection between the outer side of the steel pipe 4 and the first steel plate 1. Then, the second reinforcing rib 5 is welded to the connection between the first steel plate 1 and the steel pipe 4 respectively, thus ensuring the stability of the steel pipe 4 during use. At this time, the worker welds the two ends of the connecting pipe 6 to the two steel pipes 4 respectively, which can improve the structural strength of the connection between the two steel pipes 4. After that, the worker moves the limiting block 8 fixedly installed on one side of the second steel plate 9, and slides the limiting block 8. The limiting groove 7, connected to the top of the first steel plate 1, limits the movement direction of the second steel plate 9. After the second steel plate 9 moves to the appropriate position, the workers weld the contact area between the second steel plate 9 and the first steel plate 1, thus completing the splicing of the second steel plate 9 and the first steel plate 1, and subsequently assembling the support device. Then, the expansion bolts 10, which are embedded and fixedly installed inside the second steel plate 9, are fixedly connected to the structural plate 11. The fastening grooves 13 on the outer sides of the first steel plate 1 and the second steel plate 9 are tightly fitted to the surface of the structural plate 11, ensuring that the first... Steel plate 1 and second steel plate 9 are fixedly connected to structural plate 11. When the support device is in use, steel pipe 4 is fixedly connected to the external reinforced concrete structure through stirrups, which enables the support device to support and protect the reinforced concrete structure. Finally, after the construction of the reinforced concrete structure is completed, the workers directly pour concrete on the left side of the first steel plate 1 at the position of steel pipe 4, so that the support device can be used as part of the reinforced concrete structure. Finally, the nameplate 12 is embedded in the corner of the second steel plate 9 to facilitate the workers to understand the information of the support device.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
