Description

Technical Field

[0001] This application relates to the field of foundation pit construction technology, and in particular to a channel device. Background Technology

[0002] An excavation pit is a temporary space excavated for the construction of the underground part of a building or structure (such as a basement, foundation, bridge abutment, etc.). Excavation pits are quite deep, and on-site construction workers usually use access devices to enter the excavation pit for construction work, and can also use access devices to leave the excavation pit.

[0003] The passageway device typically includes multiple ladder cages, which can be further assembled as the foundation pit is excavated to gradually extend with the depth of the foundation pit, thereby facilitating the entry and exit of construction personnel using the passageway device.

[0004] In the existing technology, in order to enable the ladder cages of the passage device to be reused, the traditional welding connection method is abandoned and a threaded connection method is adopted between the ladder cages to facilitate the disassembly and installation of the ladder cages. However, the vibration generated by the construction workers when the ladder cages pass through can be easily transmitted and amplified in the ladder cages, and the threaded connection is prone to loosening due to vibration after long-term use, which brings a great safety hazard to the passage device. Utility Model Content

[0005] The main objective of this application is to provide a channel device that improves the existing channel device where the connection between the ladder cages is made by threaded connection, which makes it easy for vibration to be transmitted and amplified in the ladder cage, thus causing safety hazards.

[0006] To achieve the above objectives, this application proposes a channel device for installation in a foundation pit. The channel device includes a fixed support, multiple ladder cages, and multiple connecting components. The fixed support is fixedly installed at the top of the foundation pit. The multiple ladder cages are fixedly connected to each other via the connecting components and arranged along the depth direction of the foundation pit. One ladder cage closest to the top of the foundation pit is fixedly connected to the fixed support.

[0007] Each of the aforementioned connecting components includes a connector, a connector, and an elastic pad. The connector has a connecting groove extending through it along the depth direction. The connecting groove has an upper connecting portion, a receiving space, and a lower connecting portion arranged sequentially along the depth direction. The upper connecting portion is used to fixably connect to the upright of the ladder cage located above the connector. The connector is movably installed in the lower connecting portion along the depth direction. One end of the connector away from the upper connecting portion extends out of the connecting groove and is fixedly connected to the upright of the ladder cage located below the connector. The elastic pad is accommodated in the receiving space and elastically abuts against the corresponding upright and the connector, respectively.

[0008] In some embodiments of this application, a fixing block protrudes from the wall of the connecting groove, and the fixing block and the wall of the connecting groove together form the lower connecting part. One end of the connector protrudes from the abutting block, and the abutting block abuts against the fixing block. The other end of the connector extends through the slot on the side of the connecting groove away from the upper connecting part, so as to be fixedly connected to the column of the ladder cage located below the connector.

[0009] In some embodiments of this application, the upright of each ladder cage is a square tube, and the two ends of the square tube are respectively provided with mating holes. The square tube is inserted into the connecting groove. The upper connecting part is provided with a connecting hole. The square tube is fixedly connected to the upper connecting part by passing through the connecting hole and the mating hole with a screw structure.

[0010] In some embodiments of this application, the channel device further includes a plurality of wall ties, which are distributed at intervals of Xm along the depth direction. One end of each wall tie is fixedly connected to the side wall of the foundation pit, and the other end of each wall tie is fixedly connected to the ladder cage, wherein 4≦X≦6.

[0011] In some embodiments of this application, one end of the wall tie rod is fixedly connected to the side wall of the foundation pit through an embedded part of the foundation pit;

[0012] And / or, the other end of the wall tie rod is fixedly connected to the ladder cage by a clamp.

[0013] In some embodiments of this application, the channel device further includes a bracket assembly, which is fixedly disposed on the bottom wall of the pit, and the side of the bracket assembly facing away from the bottom wall of the pit is used to support the ladder cage.

[0014] In some embodiments of this application, the bracket assembly includes a base, a frame, and a plurality of bolts. The base is fixedly disposed on the bottom wall of the pit, the frame is connected to the base, and the plurality of bolts are respectively threaded to the side of the frame away from the base. The side of the bolts away from the base is used to support the ladder cage.

[0015] In some embodiments of this application, the base includes a plate and a connecting cylinder. One side of the plate is in close contact with the bottom wall of the pit, and the connecting cylinder is fixedly connected to the other side of the plate. The frame is provided with a support column that is inserted and engaged with the connecting cylinder.

[0016] In some embodiments of this application, each of the ladder cages is surrounded by a perimeter enclosure.

[0017] In some embodiments of this application, both the ladder cage near the top of the pit and the ladder cage near the bottom wall of the pit are provided with movable doors.

[0018] The channel device provided in this application embodiment, through the above-described structural configuration, allows the channel device to be suspended from the foundation pit by a fixed bracket. The ladder cage above the connecting component is suspended by the connector and connecting piece, maintaining the overall stability of the channel device. When the bottom of the channel device is on the bottom of the foundation pit, the ladder cage below the connecting component provides sufficient support for the connecting piece, and the ladder cage above the connecting component presses against the elastic pad. That is, the column below the connecting component supports the column above the connecting component through the connecting piece and the elastic pad, maintaining the overall stability of the channel device. In this way, when a ladder cage vibrates, the elastic pad absorbs some of the kinetic energy to reduce the vibration, thereby weakening or preventing the transmission and amplification of the vibration, thus improving the reliability of the connection between the ladder cages and eliminating safety hazards.

[0031] This application discloses a passage device 100 for installation in a foundation pit, allowing construction workers to enter or leave the pit. Please refer to the relevant reference. Figures 1 to 5The channel device 100 includes a fixed support 10, multiple ladder cages 20 and multiple connecting components 30. The fixed support 10 is fixedly installed on the top of the pit. The multiple ladder cages 20 are fixedly connected to each other through the connecting components 30 and arranged along the depth direction of the pit. The ladder cage 20 closest to the top of the pit is fixedly connected to the fixed support 10.

[0032] The fixed support 10 is typically fixedly connected to a support beam or concrete platform at the top of the foundation pit. Specifically, it can be anchored into the support beam or concrete platform using expansion bolts. The fixed support 10 typically comprises multiple I-beams and / or multiple channel steels. The ladder cage 20 and the fixed support 10 can be fixedly connected by welding, threaded connections, or other methods. Preferably, the ladder cage 20 and the fixed support 10 are fixedly connected by welding.

[0033] Please refer to Figure 2 Typically, each ladder cage 20 includes at least a staircase, a landing platform, and a frame for installing the staircase and landing platform, the frame including uprights 21. Considering the safety of construction workers, in some examples, the ladder cage 20 is surrounded by a perimeter fence 22, i.e., the fence 22 is fixedly installed on the frame to prevent construction workers from accidentally falling. Specifically, the ladder cage 20 near the top of the pit and the ladder cage 20 near the bottom wall of the pit are equipped with movable doors for construction workers to enter or leave the ladder cage 20. Furthermore, access control can be installed on the movable doors to prevent unauthorized personnel or those without proper authorization from entering the pit using the access device 100. In other examples, the staircase is equipped with handrails for construction workers to use for support.

[0034] Each connecting component 30 includes a connector 31, a connector 32, and an elastic pad 33. The connector 31 has a connecting groove 311 extending through it along the depth direction. The connecting groove 311 has an upper connecting part 312, a receiving space 313, and a lower connecting part 314 arranged sequentially along the depth direction. The upper connecting part 312 is used to fixally connect to the column 21 of the ladder cage 20 located above the connector 31. The connector 32 is movably installed in the lower connecting part 314 along the depth direction. One end of the connector 32 away from the upper connecting part 312 extends out of the connecting groove 311 and is fixedly connected to the column 21 of the ladder cage 20 located below the connector 31. The elastic pad 33 is accommodated in the receiving space 313 and elastically abuts against the corresponding column 21 and connector 32 respectively.

[0035] The upper connecting part 312 is typically fixedly connected to the column 21 using a detachable fixed connection method. This is intended to facilitate disassembly and installation, allowing the cage 20 to be reused. Examples include threaded connections and snap-fit ​​connections. In another example, the upper connecting part 312 may also be fixedly connected to the column 21 using a non-detachable fixed connection method, such as welding. Similarly, the connection between the connector 32 and the column 21 of the cage 20 located below the connector 31 is similar and will not be elaborated further.

[0036] It should be emphasized that the connector 32 is movably installed on the lower connecting part 314 along the depth direction. That is, the connector 32 can only move up and down relative to the lower connecting part 314 along the depth direction, and cannot rotate relative to the lower connecting part 314. After the channel device 100 is assembled, the connector 32 will not detach from the lower connecting part 314 unless there are special circumstances (e.g., the connector 31 is damaged or the connector 32 is damaged).

[0037] The passage device 100 provided in this application embodiment, through the above-described structural configuration, when the passage device 100 is suspended in the pit by the fixed bracket 10, the ladder cage 20 located above the connecting component 30 is suspended by the connector 31 and the connector 32, maintaining the overall stability of the passage device 100. When the bottom of the passage device 100 lands at the bottom of the pit, the ladder cage 20 located below the connecting component 30 can provide sufficient support for the connector 32, and the ladder cage 20 located above the connecting component 30 will press on the elastic pad 33. That is, the column 21 located below the connecting component 30 is supported by the connector 32 and the elastic pad 33, maintaining the overall stability of the passage device 100. In this way, when a ladder cage 20 vibrates, the elastic pad 33 will absorb part of the kinetic energy to reduce the vibration, thereby weakening or avoiding the transmission and amplification of the vibration, thereby improving the reliability of the connection between the ladder cages 20 and eliminating safety hazards.

[0038] In some examples, such as Figure 3 and Figure 4 As shown, a fixing block 3111 protrudes from the wall of the connecting groove 311. The fixing block 3111 and the wall of the connecting groove 311 together form the lower connecting part 314. One end of the connector 32 is provided with an abutting block 321, which abuts against the fixing block 3111. The other end of the connector 32 extends out through the groove opening on the side of the connecting groove 311 away from the upper connecting part 312, so as to be fixedly connected to the column 21 of the ladder cage 20 located below the connector 31.

[0039] Specifically, the fixing block 3111 can extend circumferentially along the connecting groove 311, that is, it can be wrapped around the groove wall of the connecting groove 311. Similarly, the abutting block 321 can extend circumferentially along the connecting member 32, that is, it can be wrapped around the connecting member 32. This is intended to increase the contact area between the fixing block 3111 and the abutting block 321, and improve the reliability of the connection between the lower connecting part 314 and the connecting member 32.

[0040] The technical solution of this embodiment not only facilitates the installation of the connector 32 from the slot on one side of the upper connecting part 312 of the connecting groove 311 onto the lower connecting part 314, improving installation efficiency, but also improves the reliability of the connection between the lower connecting part 314 and the connector 32 by the abutting block 3111 abutting against the abutting block 321.

[0041] The connector 32 is movably mounted on the lower connecting portion 314 along the depth direction. Other specific mounting methods exist. In some examples, the connecting groove 311 is provided with a guide rail along the depth direction to form the aforementioned lower connecting portion 314. The connector 32 can be directly or indirectly slidably mounted on the guide rail. The number of guide rails is not listed here, but four are preferred.

[0042] In some examples, such as Figure 3 and Figure 4 As shown, the uprights 21 of each cage 20 are square tubes, and the two ends of the square tubes are respectively provided with mating holes. The square tubes are inserted into the connecting grooves 311. The upper connecting part 312 is provided with connecting holes 3121. The square tubes are fixedly connected to the upper connecting part 312 by passing through the connecting holes 3121 and the mating holes with screws.

[0043] This design allows the square tube to be inserted into the connecting groove 311, ensuring that the peripheral wall of the square tube abuts against the inner wall of the connecting groove 311, preventing the square tube from twisting. Simultaneously, the tube is fixedly connected to the upper connecting part 312 via screws, facilitating the disassembly and assembly of the channel device 100.

[0044] In some examples, such as Figure 2 As shown, the passage device 100 also includes multiple wall ties 40, which are distributed at intervals of X m along the depth direction. One end of each wall tie 40 is fixedly connected to the side wall of the pit, and the other end of each wall tie 40 is fixedly connected to the ladder cage 20, wherein 4 ≤ X ≤ 6. This arrangement aims to improve the overall stability of the passage device 100 and effectively prevent the passage device 100 from shaking.

[0045] In some examples, one end of the wall tie 40 is fixedly connected to the side wall of the pit via an embedded part in the pit. This arrangement is intended to improve the reliability of the connection between the connector 32 and the pit.

[0046] In some examples, the other end of the wall tie 40 is fixedly connected to the ladder cage 20 by a clamp. This arrangement is intended to facilitate the connection and separation of the wall tie 40 and the ladder cage 20, thereby improving the assembly and disassembly efficiency of the passage device 100.

[0047] In some examples, such as Figure 5 As shown, the passage device 100 also includes a bracket assembly 50, which is fixedly mounted on the bottom wall of the pit. The side of the bracket assembly 50 facing away from the bottom wall of the pit is used to support the ladder cage 20. This arrangement aims to keep the ladder cage 20, which is far from the top of the pit, away from the bottom wall, thus reducing damage to the ladder cage 20 and allowing for better reuse. Furthermore, the bottom of the passage device 100 rests on the bottom of the pit, meaning the bracket assembly 50 is fixed to the bottom wall of the pit, providing stable support for the entire passage device 100.

[0048] In some examples, such as Figure 5 As shown, the bracket assembly 50 includes a base 51, a frame 52, and multiple bolts 53. The base 51 is fixedly installed on the bottom wall of the pit. The frame 52 is connected to the base 51. The multiple bolts 53 are threadedly connected to the side of the frame 52 away from the base 51. The side of the bolts 53 away from the base 51 is used to support the ladder cage 20.

[0049] With this configuration, the height of the bracket assembly 50 can be adjusted by rotating bolt 53, allowing the bracket assembly 50 to better support the ladder cage 20. Figure 2 and Figure 5 As shown, in this example, each ladder cage 20 includes four uprights 21, and the bracket assembly 50 includes four bolts 53 corresponding to the four uprights 21.

[0050] In some examples, such as Figure 5 As shown, the base 51 includes a plate 511 and a connecting cylinder 512. One side of the plate 511 is tightly attached to the bottom wall of the pit, and the connecting cylinder 512 is fixedly connected to the other side of the plate 511. The frame 52 is provided with a support column 521 that is inserted and engaged with the connecting cylinder 512. This arrangement is intended to facilitate the assembly and disassembly of the bracket assembly 50, and at the same time, to facilitate the adjustment of the bolts 53 on the frame 52 corresponding one-to-one with the columns 21.

[0051] The number of support columns 521 is usually set one-to-one with the number of upright columns 21. In some examples, the frame 52 includes connecting rods (not shown) for connecting the support columns 521. Specifically, the connecting rods are perpendicular to the support columns 521, and their two ends are fixedly connected to two support columns 521 respectively.

[0052] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
