Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a foundation pit retaining component for civil buildings. Background Art

[0002] When building a house, it is necessary to dig a foundation pit. When constructing the foundation pit, it is usually necessary to carry out retaining treatment on the foundation pit. The retaining of the foundation pit is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and to adopt a support, reinforcement and protection measure for the side walls of the foundation pit and the surrounding environment. A Chinese utility model patent with the announcement number CN220394562U discloses a foundation pit retaining structure for house construction. When in use, it can divert rainwater to prevent the inner wall of the foundation pit from softening and collapsing. After use, it can be folded and stored to reduce the occupied space. At the same time, the structure is simple and the use cost is reduced.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the height of the support frame is fixed, and the depth of the foundation pit needs to be determined according to the height of the house to be built, which is not suitable for deeper foundation pits, and the overall integrated design of the structure makes the length of the entire support frame longer after folding. For this reason, we designed a civil building foundation pit retaining assembly. Utility Model Content

[0004] In order to solve the technical problem that the height of the support frame cannot be adjusted and is not suitable for foundation pits of various depths, the utility model provides a civil building foundation pit retaining assembly.

[0005] The utility model is implemented by the following technical scheme: a civil building foundation pit retaining assembly, including two linearly arranged brackets, an extension frame is installed above the two brackets, a plurality of baffles distributed at equal intervals are installed between the two extension frames and the brackets, an axis plate is installed above the front surface of the bracket, an axis plate is also arranged above the extension frame, a support rod is rotatably installed on the axis plate through an axis pin, and a plug-in rod is arranged inside the support rod for sliding up and down.

[0006] As a further improvement of the above scheme, the bracket is provided with a plurality of linearly distributed plug-in interfaces 1, the extension frame is provided with a plurality of linearly distributed plug-in interfaces 2, and plug-in boards are provided at both ends of the left and right sides of the baffle. The baffle is plugged into the bracket and the extension frame through the plug-in boards. The baffle can be installed on two brackets or two extension frames through the plug-in boards, and can be quickly disassembled, thereby facilitating storage and placement.

[0007] As a further improvement of the above scheme, the length and width of the socket one are exactly the same as the length and width of the socket two, and the length of the plug board is half the depth of the socket one, so that multiple brackets can be distributed in parallel in sequence, so that a baffle can be set between every two adjacent brackets and extension frames, which is suitable for foundation pits of various lengths and widths.

[0008] As a further improvement of the above scheme, the upper part of the bracket is recessed downward to form a lower docking interface, and the bottom end of the lower docking interface is below the bottom of the topmost plug-in interface 1. The lower end of the extension frame is provided with a docking rod matching the lower docking interface, and a plug-in interface 2 is provided on the docking rod, and an upper docking interface that is completely consistent with the lower docking interface is provided on the top of the extension frame. The extension frame can be installed on the top of the bracket as needed, and the extension frames can also be spliced ​​up and down, which is suitable for foundation pits of various depths.

[0009] As a further improvement of the above scheme, a base plate is welded to the bottom end of the front surface of the bracket, and a socket is opened on the base plate. Fixing nails are inserted into the socket up and down. After the bracket is placed, the fixing nails are inserted into the ground through the socket, which can fix the bracket to a certain extent and facilitate the subsequent fixed support of the plug-in rod.

[0010] As a further improvement of the above solution, the bottom end of the support rod is recessed upward to form a plug-in hole, and movable sliding holes are formed through the left and right sides of the support rod, and the movable sliding holes are connected to the plug-in holes, so that the plug-in rod can move inside the support rod, and then it can be quickly plugged into the ground;

[0011] The plug-in rod is slidably placed in the plug-in hole, and a round hole is opened on the plug-in rod. A locking bolt is inserted in the round hole, and a locking nut is threadedly connected to the locking bolt. After the plug-in rod is plugged into the ground, the locking nut is tightened to fix it.

[0012] As a further improvement of the above solution, a sharp portion is provided at the bottom end of the plug-in rod, and a pedal is welded on the plug-in rod, so that a person can fix the pedal downward on the ground with his foot;

[0013] The support rod is provided with a storage opening, the width of which is smaller than the width of the plug hole and larger than the width of the pedal. When the plug rod is stored, the pedal can move upward through the storage opening, which is convenient for its overall movement and storage.
