Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a detachable foundation pit support device for building construction. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings. Waterproofing and drainage work should be done. For shallow excavations, slope protection can be used to stabilize the soil slope. The slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods can be used. Therefore, a detachable excavation pit support device for building construction is used to support the excavation pit.

[0003] Existing technologies, such as patent CN218373918U, disclose a support device for foundation pits. This patent uses a base, a lifting plate, and a mounting frame. A motor is fixedly mounted on the upper surface of the mounting frame, and a screw is fixedly connected to the output end of the motor. A moving block is threadedly connected to the circumferential side of the screw, and connecting rods are hinged to both sides of the moving block. A support plate is hinged to one end of each connecting rod. Guide grooves are provided on both sides of the lifting plate, and guide rods are slidably connected within the guide grooves. The guide rods are fixedly connected to the support plate. This utility model device solves the problems of existing foundation pit support devices, such as the inability of the support plate to be adjusted according to the size of the foundation pit, and the inability to support only one inner wall of the foundation pit, resulting in poor support performance.

[0004] In daily operation, the existing equipment is difficult to adapt to foundation pits of different depths, requiring different models of equipment for support, which makes the equipment difficult to use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment is unable to quickly support foundation pits of different depths, and to propose a detachable foundation pit support device for building construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable foundation pit support device for building construction, comprising a base, a support plate, a connecting arm, a positioning block, and a connecting head. The support plate is positioned above the base. The positioning block is fixedly connected to the side of the support plate. The connecting arm is rotatably connected inside the positioning block. The connecting head is fixedly connected to the end of the connecting arm away from the positioning block. An adjustment device is provided at the upper end of the base. The adjustment device includes a first threaded rod and a connecting column. The first threaded rod is fixedly connected to the lower end of the connecting head. The connecting column is fixedly connected to the upper end of the base. The first threaded rod moves up and down inside the connecting column. A rotating groove is opened at the upper end of the connecting column. A gear is rotatably connected inside the rotating groove. A first nut is fixedly connected to the upper end of the gear. The first nut is threadedly connected to the surface of the first threaded rod. A connecting seat is fixedly connected to the side of the connecting column.

[0007] Furthermore, a connecting block is fixedly connected to the upper end of the connecting seat, and a locking rod is slidably connected inside the connecting block. By setting the locking rod, the gear can be limited, reducing the situation where the gear rotates randomly during use and it is difficult to effectively fix the threaded rod.

[0008] Furthermore, a spring is fixedly connected to one end of the lever, and the end of the spring away from the lever is fixedly connected to the inside of the connecting block. The spring is provided to facilitate the application of a restoring force to the lever.

[0009] Furthermore, the end of the lever away from the spring engages with the surface of the gear.

[0010] Furthermore, a connecting device is provided on the surface of the support plate. The connecting device includes a fixing block and a connecting cylinder. The fixing block is fixedly connected to the side of the support plate, and the connecting cylinder is located on the side of the support plate. A stabilizing block is provided inside the fixing block. A second threaded rod is fixedly connected to one end of the stabilizing block. The end of the second threaded rod away from the stabilizing block is rotatably connected to the inside of the connecting cylinder. By providing the second threaded rod, both ends of the connecting cylinder can be extended, reducing the difficulty of the connecting cylinder effectively supporting the two support plates during use.

[0011] Furthermore, a mounting block is fixedly connected to the surface of the connecting cylinder, and a rotating tube is rotatably connected inside the mounting block. The rotating tube facilitates the limiting rotation of the second nut.

[0012] Furthermore, a second nut is fixedly connected to one end of the rotating tube, and the second nut is threadedly connected to the surface of the second threaded rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when using the equipment, the user places the base inside the foundation pit and then supports the support plate at both ends of the foundation pit. When using the equipment, the user moves the clamping rod, which causes the spring to deform and generate elastic force. The clamping rod then disengages from the surface of the gear, and the rotating gear drives the first nut to rotate. The first nut then drives the first threaded rod to move upward inside the connecting column, moving the connector. By setting an adjustment device, the height of the connector can be effectively adjusted, thus reducing the difficulty of adapting existing equipment to foundation pits of different depths, requiring different models of equipment for support, which makes the equipment difficult to use. This adjustment device allows for flexible adjustment of the support plate height to adapt to foundation pits of different depths, greatly improving adaptability to different construction scenarios and meeting diverse foundation pit support needs.

[0015] 2. In this utility model, by setting a connecting device, when the user rotates the rotating tube during use, the rotating tube drives the second nut to rotate, and the second nut drives the second threaded rod to rotate. When the second threaded rod rotates, it drives the stabilizing block to extend and connect and fix the support plate. By setting a connecting device, the support plate is effectively connected, which plays a role in the installation and positioning of the support plate. This reduces the possibility of the support plate rotating easily during use, making it difficult for the support plate to effectively support the foundation pit. This connecting device effectively supports and connects the support plate, improving the practicality of the equipment. Attached Figure Description

The support plate 2 is located above the base 1. The positioning block 4 is fixedly connected to the side of the support plate 2. The connecting arm 3 is rotatably connected inside the positioning block 4. The connector 5 is fixedly connected to the end of the connecting arm 3 away from the positioning block 4.

[0023] The specific settings and functions of its adjustment device 6 and connecting device 7 will be described in detail below.

[0024] In this embodiment: An adjustment device 6 is provided at the upper end of the base 1. The adjustment device 6 includes a first threaded rod 61 and a connecting post 62. The first threaded rod 61 is fixedly connected to the lower end of the connector 5. The connecting post 62 is fixedly connected to the upper end of the base 1. The first threaded rod 61 moves up and down inside the connecting post 62. A rotating groove 65 is provided at the upper end of the connecting post 62. A gear 63 is rotatably connected inside the rotating groove 65. A first nut 64 is fixedly connected to the upper end of the gear 63. The first nut 64 is threadedly connected to the surface of the first threaded rod 61. A connecting seat 66 is fixedly connected to the side of the connecting post 62.

[0025] Specifically, a connecting block 67 is fixedly connected to the upper end of the connecting seat 66, and a locking rod 68 is slidably connected inside the connecting block 67.

[0026] In this embodiment, by setting the locking rod 68, the gear 63 can be limited, reducing the possibility of the gear 63 rotating freely during use and making it difficult to effectively fix the threaded rod.

[0027] Specifically, a spring 69 is fixedly connected to one end of the lever 68, and the end of the spring 69 away from the lever 68 is fixedly connected to the inside of the connecting block 67. The spring 69 is provided to facilitate the application of a reset force to the lever 68.

[0028] Specifically, the end of the lever 68 away from the spring 69 engages with the surface of the gear 63.

[0029] In this embodiment: a connecting device 7 is provided on the surface of the support plate 2. The connecting device 7 includes a fixing block 71 and a connecting cylinder 74. The fixing block 71 is fixedly connected to the side of the support plate 2. The connecting cylinder 74 is located on the side of the support plate 2. A stabilizing block 72 is provided inside the fixing block 71. A second threaded rod 73 is fixedly connected to one end of the stabilizing block 72. The end of the second threaded rod 73 away from the stabilizing block 72 is rotatably connected to the inside of the connecting cylinder 74.

[0030] In this embodiment: the second threaded rod 73 is provided to extend both ends of the connecting cylinder 74, reducing the difficulty for the connecting cylinder 74 to effectively support the two support plates 2 during use.

[0031] Specifically, a mounting block 77 is fixedly connected to the surface of the connecting cylinder 74, and a rotating tube 76 is rotatably connected inside the mounting block 77. The rotating tube 76 is provided to facilitate the limiting rotation of the second nut 75.

[0032] Specifically, one end of the rotating tube 76 is fixedly connected to the second nut 75, and the second nut 75 is threadedly connected to the surface of the second threaded rod 73.

[0033] Working Principle: When using the equipment, the user places the base 1 inside the pit and then supports the support plate 2 at both ends of the pit. During use, the user moves the lever 68, causing the spring 69 to deform and generate elastic force. The lever 68 then disengages from the surface of the gear 63, and the rotating gear 63 drives the first nut 64 to rotate. The first nut 64 then drives the first threaded rod 61 to move upwards inside the connecting column 62, moving the connector 5. By setting the adjustment device 6, the height of the connector 5 can be effectively adjusted, thus reducing the difficulty of adapting existing equipment to pits of different depths, requiring different models of equipment for support, and making the equipment difficult to use. This adjustment device 6 allows for flexible adjustment of the height of the support plate 2 to adapt to pits of different depths, greatly improving adaptability to different construction scenarios and meeting diverse pit support needs.

[0034] When the equipment is in use, the user rotates the rotating tube 76, which in turn drives the second nut 75 to rotate. The second nut 75 then drives the second threaded rod 73 to rotate. When the second threaded rod 73 rotates, it causes the stabilizing block 72 to extend and connect to and fix the support plate 2. By setting the connecting device 7, the support plate 2 is effectively connected, serving to position and install it. This reduces the risk of the support plate 2 rotating during use, which could make it difficult for the support plate 2 to effectively support the foundation pit. This connecting device 7 effectively supports and connects the support plate 2, improving the practicality of the equipment.
