Abstract
Description
Technical Field
[0001] This invention relates to the field of building foundation pit support technology, and in particular to a retractable anti-sliding retaining device for building foundation pit support. Background Technology
[0002] During the construction of a building foundation pit, retaining devices are key equipment to ensure the safety of the construction. Their main function is to support the soil on the side walls of the foundation pit, prevent the soil from collapsing or sliding, and provide a stable working environment for construction personnel and equipment.
[0003] For example, a pressure-reinforcing device for foundation pit support, disclosed in CN211773705U, includes a pressure-reinforcing mechanism. Two mudguards are fitted together on both sides of the inner wall of the foundation pit, and the pressure-reinforcing mechanism is located between the two mudguards. The pressure-reinforcing mechanism is used to compress the mudguards. The pressure-reinforcing mechanism includes a support block, a column, a base, a support rod, and a limiting block. The column is fixedly connected to the side of the mudguard away from the foundation pit. The column is a cylindrical structure with its central axis in a vertical direction. The bottom of the column is inserted into the bottom surface of the foundation pit. Several limiting blocks are fixedly connected to the column. The base is connected to the bottom surface of the foundation pit and is detachably connected to the support block. One end of the support rod is rotatably connected to the support block, and the other end of the support rod is located on the bottom surface of the limiting block and compresses against the limiting block. There are two pressure-reinforcing mechanisms, each located between two mudguards. This device solves the technical problems existing in the prior art, such as: the installation and disassembly are relatively troublesome, the effect of resisting soil pressure is generally poor, and it does not have prestress. However, because the mudguard of the foundation pit support is an integral fixed structure, when a part of the mudguard is damaged due to soil impact or collision, the damaged part cannot be replaced individually. Instead, the entire mudguard must be removed and replaced as a whole. This not only causes serious waste of materials and increases construction costs, but also prolongs the construction period. Furthermore, it is impossible to flexibly adjust the retaining area and support length according to the actual size and shape of the foundation pit, making it difficult to meet the support requirements of foundation pits of different specifications.
[0004] Therefore, a retractable anti-sliding retaining device for building foundation pit support has now been developed, which allows for individual replacement of damaged baffles and flexible adjustment of the number of baffles. Summary of the Invention
[0005] To overcome the shortcomings of existing foundation pit support devices, such as mudguards being a fixed, integrated structure that cannot individually replace damaged parts and is difficult to meet the support requirements of foundation pits of different specifications, this invention provides a telescopic anti-sliding retaining device for building foundation pit support that allows for individual replacement of damaged mudguards and flexible adjustment of the number of mudguards.
[0006] The technical solution is: a telescopic anti-sliding retaining device for building foundation pit support, including a mounting frame, baffles, support rods, fixing seats, fixing screws and stabilizing components. Multiple baffles are snapped onto the mounting frame. Support rods are connected to the right sides of the front and rear parts of the mounting frame through damping rotation. Fixing seats are connected to the lower side of the support rods through damping rotation. Fixing screws are threadedly connected to the front and rear parts of the mounting frame. Stabilizing components are provided on the fixing screws to enhance the stability of the inserted soil.
[0007] Furthermore, each mounting base is equipped with multiple insert rods.
[0008] Furthermore, each fixing screw is equipped with a knob on its upper part.
[0009] Furthermore, the lower part of the fixing screw is a tapered structure.
[0010] Furthermore, the stabilizing component includes a pressure rod, a screw block, a rotating cover, a limiting block, a guide block, and a connecting block. Each fixed screw is connected to a pressure rod via a damped sliding connection. Each fixed screw is connected to a screw block on its upper side. Each pressure rod is rotatably connected to a rotating cover on its upper side. Each pressure rod is connected to a connecting block on its lower side. Each connecting block is rotatably connected to multiple limiting blocks. Each fixed screw is connected to multiple guide blocks on its lower part. Each guide block is movably connected to an adjacent limiting block.
[0011] Furthermore, it also includes a splicing assembly, which includes a rotating block, a rotating handle, and a rotating shaft. Multiple rotating shafts are connected to the front side of the mounting plate frame via a damped rotational connection. Rotating blocks are connected to both the left and right sides of the rotating shaft, and rotating handles are connected to the right side of the rotating shaft.
[0012] The beneficial effects are as follows: 1. When a baffle is damaged, the present invention can simply remove the damaged baffle upwards and replace it with a new baffle. There is no need to replace the whole baffle. The operation is simple and convenient, which effectively reduces material waste and construction costs.
[0013] 2. This invention achieves continuous splicing of multiple baffles by inserting them one by one into the mounting frame from top to bottom. When supporting the foundation pit, the number of baffles can be flexibly increased or decreased according to the actual support length of the foundation pit to adapt to the support requirements of foundation pits of different specifications.

Detailed Implementation
[0020] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
[0021] A retractable anti-sliding retaining device for building foundation pit support, such as Figures 1-5 As shown, the device includes a mounting frame 1, baffles 11, support rods 12, fixing seats 13, fixing screws 14, and stabilizing components. Six baffles 11 are snapped onto the mounting frame 1. Support rods 12 are connected to the front and rear right sides of the mounting frame 1 via damping rotation. Fixing seats 13 are connected to the lower side of the support rods 12 via damping rotation. Each fixing seat 13 is equipped with four insert rods for easy fixing to the bottom of the pit. Fixing screws 14 are threaded to the front and rear of the mounting frame 1. Each fixing screw 14 is equipped with a knob on its upper part for easy gripping and rotation. The lower part of each fixing screw 14 has a conical structure for easy insertion into the soil. Stabilizing components are provided on the fixing screw 14.
[0022] like Figures 1-3 As shown, the stabilizing assembly includes a pressure rod 15, a screw block 16, a rotating cover 17, a limiting block 18, a guide block 19, and a connecting block 110. The pressure rod 15 is connected to the fixing screw 14 via a damping sliding mechanism. The screw block 16 is connected to the upper side of the fixing screw 14. The rotating cover 17 is rotatably connected to the upper side of the pressure rod 15. The connecting block 110 is connected to the lower side of the pressure rod 15. Four limiting blocks 18 are rotatably connected to the connecting block 110. Eight guide blocks 19 are connected to the lower part of the fixing screw 14. The guide blocks 19 are movably connected to the adjacent limiting blocks 18.
[0023] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a splicing assembly, which includes a rotating block 2, a rotating handle 21 and a rotating shaft 22. Four rotating shafts 22 are connected to the front side of the mounting plate frame 1 by a damped rotational connection. The rotating blocks 2 are connected to both the left and right sides of the rotating shaft 22, and the rotating handles 21 are connected to the right side of the rotating shaft 22.
[0024] When using this invention, firstly, according to the support requirements of the foundation pit, take the corresponding number of installation plate frames 1, and then fix the installation plate frames 1 to the inner wall of the foundation pit through the support rod 12 and the fixing seat 13. By rotating the rotating shaft 22 through the rotating handle 21, the rotating block 2 is driven to rotate, so that the rotating block 2 is inserted into another installation plate frame 1, thereby continuously splicing the installation plate frames 1 together, improving the overall support stability. The baffle 11 supports and blocks the soil on the side wall of the foundation pit, preventing the soil from collapsing or sliding.
[0025] By rotating the fixing screw 14, the fixing screw 14 moves downward and inserts into the soil. Then, the pressure rod 15 is pushed downward, which drives the connecting block 110 to move downward, thereby pushing the limiting block 18 to move downward. Guided by the guide block 19, the limiting block 18 rotates outward and inserts into the soil, which strengthens the stability of the fixing screw 14 and prevents the fixing screw 14 from loosening. This improves the stability of the mounting frame 1 and prevents the mounting frame 1 from tipping over. Then, the rotating cover 17 is installed on the screw block 16 to fix the pressure rod 15.
[0026] By inserting the baffles 11 one by one from top to bottom into the mounting frame 1, multiple baffles 11 can be continuously spliced together. When supporting the foundation pit, the number of baffles 11 can be flexibly increased or decreased according to the actual support length of the foundation pit to adapt to the support requirements of foundation pits of different specifications.
[0027] When a baffle 11 is damaged, simply remove the damaged baffle 11 upwards and replace it with a new baffle 11. There is no need to replace the whole baffle. The operation is simple and convenient, effectively reducing material waste and construction costs.
[0028] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
