Description

Technical Field

[0001] This utility model relates to the field of foundation pit support, specifically a support device for a pit within a pit. Background Technology

[0002] Many pit-within-pit structures often exist in existing foundation pits. These pit-within-pit structures require support devices for protection to prevent collapse. The existing support method is generally to weld multiple support rods together according to the size of the pit-within-pit to support pits of different lengths. However, this support structure has low construction efficiency. The length of the connectors needs to be cut or welded according to the size of the pit-within-pit, which further increases the workload and reduces the efficiency and convenience of the support structure construction. Utility Model Content

[0003] The purpose of this utility model is to provide a support device for pit-within-pit structures, which can solve the technical problems of low construction efficiency and large workload of existing support structures, improve the efficiency and convenience of support construction for pit-within-pit structures of different sizes, and ensure the stability of the support structure.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A support device for a pit-within-a-pit includes multiple support rods in contact with the sidewalls of the pit. Vertical and horizontal connectors are symmetrically arranged between the support rods. Each vertical connector includes end rods and a middle rod. Each horizontal connector includes a horizontal bar and an adjusting rod positioned between the horizontal bars on the left and right sides. The two ends of the end rods are connected to the upper and lower horizontal bars, respectively. The two ends of the middle rod are connected to the adjusting rods on the upper and lower sides, respectively. The adjusting rod is threadedly connected to the horizontal bars on both sides. The adjusting rod has multiple transversely movable connectors. The two ends of the middle rod are movably connected to the connectors on the upper and lower sides, respectively. Symmetrically arranged connecting plates are provided on each connector, and each connecting plate is connected to one of the support rods.

[0006] Furthermore, a rotating sleeve is rotatably connected to the connector head, and the rotating sleeve is threaded to the outside of the adjusting rod.

[0007] Furthermore, the width of the rotating sleeve is greater than the width of the connector.

[0008] Furthermore, L-shaped connecting blocks are symmetrically arranged on both sides of the connector, and the connecting plate is set at the top of the vertical part of the L-shaped connecting block. The connecting plate is connected to the side of the support rod.

[0009] Furthermore, the connector head is provided with a U-shaped block, and the end of the central vertical rod is movably inserted into the interior of the U-shaped block.

[0010] Furthermore, diagonal braces are provided between the end vertical rod and the horizontal rod, and between the middle vertical rod and the adjusting rod.

[0011] Furthermore, both the vertical and horizontal connecting parts are connected to the support rod by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model includes horizontal and vertical connectors between multiple support rods. The horizontal connectors include horizontal rods and adjusting rods disposed between the horizontal rods on both sides. The vertical connectors include end vertical rods and middle vertical rods. The two ends of the end vertical rods are respectively connected to the upper and lower horizontal rods, and the two ends of the middle vertical rods are respectively connected to the upper and lower adjusting rods. The adjusting rods are threadedly connected to the horizontal rods on both sides. When supporting pits of different lengths, this structure only requires rotating the adjusting rods to adjust their length by threading them with the horizontal rods on both sides. This allows for adaptive adjustment of the dimensions of the horizontal connectors without the need for cutting or welding the connectors, greatly reducing the workload of construction, improving construction efficiency and convenience, and meeting the support needs of pits of different lengths.

[0014] 2. Multiple transversely movable connectors are installed on the adjusting rod. The two ends of the central vertical rod are movably connected to the connectors on the upper and lower sides, respectively. Connecting plates are symmetrically provided on the connectors, and the connecting plates are connected to one of the support rods. This structure allows for the adaptive installation of multiple connectors according to the length of the adjusting rod. After the connector is moved laterally to the designated position, its connecting plate is connected to the support rod. Then, the central vertical rod is connected between the upper and lower connectors. This structure allows for the adaptive installation of multiple central vertical rods according to the length of the adjusting rod, thus enabling the installation of multiple central vertical rods when supporting pits of different lengths. This improves the stability of the support structure. Furthermore, the central vertical rod is connected to both the adjusting rod and the support rod, further enhancing the stability and effectiveness of the support at the central position and improving the overall stability of the pit-in-pit structure.

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] Reference Figure 1 and Figure 2This utility model describes a support device for a pit-within-a-pit structure. The main structure includes multiple support rods 1 that contact the sidewalls of the pit-within-a-pit. The support rods 1 are installed on the sidewalls of the pit-within-a-pit. Specifically, the support rods 1 on the upper and lower sides are arranged in a horizontal array, and the support rods 1 on the left and right sides are arranged in a vertical array. Vertical and horizontal connectors are symmetrically arranged between the multiple support rods 1. The horizontal connectors are installed on the upper and lower support rods 1 to connect the horizontally arrayed support rods 1, and the vertical connectors are installed on the left and right support rods 1 to connect the vertically arrayed support rods 1. The ends of the horizontal connectors are connected to the ends of the vertical connectors. This ensures that the entire support structure is stably installed on the sidewalls of the pit-within-a-pit. To effectively protect the pit-within-a-pit structure, the vertical connecting members include end vertical rods 2 and middle vertical rods 3. The end vertical rods 2 are located on the side wall of the pit-within-a-pit and are used to connect multiple vertical support rods 1, as well as the ends of the horizontal connecting members on the upper and lower sides. The middle vertical rods 3 are used to connect and support the middle positions of the horizontal connecting members on the upper and lower sides. When the length of the pit-within-a-pit is long, the length of the horizontal connecting members is also long, and the middle lacks effective support. Therefore, multiple middle vertical rods 3 are used to support the middle of the suspended horizontal connecting members, further improving the stability of the entire support structure. The horizontal connecting members include horizontal rods 4 and adjusting rods 5 set between the horizontal rods 4 on the left and right sides. The two ends of the end vertical rods 2 are respectively connected to the horizontal rods 4 on the upper and lower sides by bolts. Alternatively, a welding connection can be used. The two ends of the central vertical rod 3 are connected to the upper and lower adjusting rods 5 respectively. The adjusting rods 5 are threadedly connected to the horizontal rods 4 on both sides. This structure allows for the selection of an adjusting rod 5 of appropriate length when supporting pits of different lengths. Preferably, the adjusting rod 5 can be composed of multiple rods connected by threads, further improving the adaptability of the adjusting rod 5's length. By assembling its two ends with the horizontal rods 4 on both sides through threaded connections, the length of the resulting transverse connecting piece matches the length of the pit, eliminating the need for cutting or welding the connecting piece, greatly reducing the workload, improving construction efficiency and convenience, and meeting the support needs of pit structures of different lengths. The adjusting rod 5 is equipped with multiple... Multiple transversely movable connectors 6, each capable of lateral movement relative to the adjusting rod 5, are connected at both ends of the central vertical rod 3 to the upper and lower connectors 6 respectively. The number of connectors 6 can be set according to the length of the adjusting rod 5, and the connectors 6 are moved to designated positions at certain intervals. Then, the central vertical rod 3 is connected between the upper and lower connectors 6. This structure allows for the adaptive setting of a corresponding number of central vertical rods 3 according to the length of the pit within the pit, thereby using multiple central vertical rods 3 to support the middle of the suspended transverse connector, improving the transverse support effect. Connecting plates 7 are symmetrically fixed to the connectors 6 by welding or bolts, and the connecting plates 7 are connected to one of the support rods 1.After the connector 6 moves into position along the adjusting rod 5, its connecting plate 7 connects to the nearest support rod 1. This allows the connector 6 to connect to both the adjusting rod 5 and the support rod 1 simultaneously, making the central vertical rod 3 between the upper and lower connectors 6 more robust and further improving the overall stability of the support structure.

[0022] Preferred, refer to Figure 3 The connector 6 is rotatably connected to a rotating sleeve 8 via a bearing. Specifically, a fixing ring is provided on the connector 6, and the rotating sleeve 8 is rotatably connected inside the fixing ring via a bearing. The rotating sleeve 8 is threadedly connected to the outside of the adjusting rod 5, and the rotating sleeve 8 is sleeved on the outside of the adjusting rod 5. This structure allows the rotating sleeve 8 to rotate and move along the adjusting rod 5 under the action of the threaded connection when it is rotated, so that the connector 6 rotatably connected to it can move along the adjusting rod 5. This makes the movement and adjustment of the connector 6 relative to the adjusting rod 5 more efficient and convenient. After adjustment, the threaded connection between the rotating sleeve 8 and the adjusting rod 5 can be used to keep the connector 6 in the specified position, further improving the stability of the position of the connector 6.

[0023] Preferably, the width of the rotating sleeve 8 is greater than the width of the connector 6. This structure allows the two sides of the rotating sleeve 8 to extend outward relative to the two sides of the connector 6 by a certain distance. Therefore, when adjusting the position of the connector 6, it is only necessary to hold the extended parts on both sides of the rotating sleeve 8 and rotate them. The relative structure of the rotating sleeve 8 and the connector 6 is more reasonable, which improves the convenience of adjusting the position of the connector 6.

[0024] Preferably, L-shaped connecting blocks 9 are symmetrically fixed to both sides of the connector 6 by welding or integral molding. The connecting plate 7 is fixed to the top of the vertical part of the L-shaped connecting block 9 by welding or integral molding. The connector 6 and the horizontal part of the L-shaped connecting block 9 are fixedly connected by welding or integral molding. The connecting plate 7 is connected to the side of the support rod 1, specifically by bolts. This structure allows the connector 6 to be connected and fixed to the support rod 1 through the connecting plate 7 at the top of the L-shaped connecting blocks 9 on both sides, further improving the firmness of the connector 6 relative to the support rod 1. This makes it less likely for the connected connector 6 to move relative to the adjusting rod 5 after connection, further improving the structural firmness of the connector 6 relative to the adjusting rod 5.

[0025] Preferably, a U-shaped block 10 is fixed to the connector 6 by welding or integral molding, and the end of the central vertical rod 3 is movably inserted into the interior of the U-shaped block 10. This structure makes the connection operation of the central vertical rod 3 and the U-shaped block 10 simpler and more convenient. After the two are inserted and matched, they are connected by bolts, making the resulting connection structure more robust.

[0026] Preferably, diagonal braces 11 are provided between the end vertical rod 2 and the horizontal rod 4, and between the middle vertical rod 3 and the adjusting rod 5. The diagonal braces 11 can improve the relative structural stability between the horizontal and vertical connecting parts, avoid bending deformation when the length is too long, and further improve the stability of the support structure.

[0027] Preferably, both the vertical and horizontal connectors are connected to the support rod 1 by bolts. This structure allows the bolts to be pre-anchored to the side wall of the pit within the pit. After the support rod 1 is fitted onto the anchored bolts, the horizontal or vertical connector is fitted onto the outside of the bolts and finally fixed with nuts. This not only connects and fixes the horizontal connectors, vertical connectors, and support rod 1, but also makes the formed support structure more firmly connected to the side wall of the pit within the pit, further improving the stability of the support structure.

[0028] Working Principle: The structure of this utility model features horizontal and vertical connectors between multiple support rods 1. The horizontal connectors include horizontal bars 4 and adjusting rods 5 positioned between the horizontal bars 4 on both sides. The vertical connectors include end vertical bars 2 and middle vertical bars 3. The two ends of the end vertical bars 2 are connected to the upper and lower horizontal bars 4 respectively, and the two ends of the middle vertical bars 3 are connected to the upper and lower adjusting rods 5 respectively. The adjusting rods 5 are threadedly connected to the horizontal bars 4 on both sides. This structure allows for easy adjustment of the length of pits of different lengths when supporting them, simply by rotating the adjusting rods 5 to adjust their length through threaded engagement with the horizontal bars 4. This enables adaptive adjustment of the dimensions of the horizontal connectors, eliminating the need for cutting or welding adjustments, significantly reducing construction workload, improving efficiency and convenience, and meeting the support requirements for pits of different lengths. The adjusting rods 5 are equipped with… Multiple transversely movable connectors 6 are provided. The two ends of the central vertical rod 3 are movably connected to the upper and lower connectors 6 respectively. Connecting plates 7 are symmetrically provided on the connectors 6. The connecting plates 7 are connected to one of the support rods 1. This structure can adaptively set multiple connectors 6 according to the length of the adjusting rod 5. After the connector 6 is moved laterally to the designated position, the connecting plates 7 on it are connected to the support rod 1. Then, the central vertical rod 3 is connected between the upper and lower connectors 6. This structure can adaptively set multiple central vertical rods 3 according to the length of the adjusting rod 5. Thus, multiple central vertical rods 3 can be adaptively set when supporting pits of different lengths, thereby improving the stability of the support structure. In addition, the central vertical rod 3 is connected to both the adjusting rod 5 and the support rod 1, further improving the stability and effectiveness of the support at the central position and improving the stability of the entire pit-in-pit structure.
