Description

Technical Field

[0001] This utility model relates to the field of foundation pit protection technology, specifically a foundation pit protection frame. Background Technology

[0002] During the construction of a building, it is necessary to excavate a foundation pit. The foundation pit is a pit dug at the foundation design location according to the foundation elevation and foundation plane dimensions. Since the foundation pit is quite deep, in order to prevent the foundation pit from collapsing, protective devices need to be set up around the foundation pit to improve the safety of construction.

[0003] The utility model with announcement number CN221545642U discloses a foundation pit protection frame, including a foundation pit, with protective structures provided on the sides of the foundation pit. The protective structures include multiple protective components and multiple sets of support components, which are arranged vertically. Each set of support components is composed of multiple support components, and each set of support components corresponds to one protective component. The protective components include a first baffle, multiple second baffles, and a third baffle, which are arranged sequentially. The support components include an installation assembly, on which support components are provided.

[0004] Existing foundation pit protection frames can be installed in stages as the excavation depth progresses, preventing collapse during excavation. However, while these frames can be installed in stages, the combination of protective components (such as baffles 1, 2, and 3) and supporting components is relatively fixed. This makes it difficult to flexibly adjust the specific parameters of the protection structure for foundation pits of different shapes and sizes, resulting in poor adaptability. Furthermore, the installation process of existing frames can be complex, requiring significant manual labor and time for the vertical arrangement and assembly of multiple protective and supporting components. The lack of convenient adjustment mechanisms also makes fine-tuning the protection structure after installation difficult. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a foundation pit protection frame, which solves the existing problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit protection frame, comprising:

[0007] A protective plate, which is attached to the side wall of the pit to prevent the pit from collapsing.

The two connecting plates 22 are respectively installed on the protective plate 1 and the bottom of the pit by bolts.

[0029] Specifically, the upper support member 3 is located between the upper outer sides of the two protective plates 1. The upper support member 3 connects the two symmetrical protective plates 1 through an adjustable mechanism to support the upper end of the protective plates 1. The upper support member 3 includes a bonding plate 31, which is bolted to the upper outer side of one of the protective plates 1. A fixing sleeve 32 is fixed to the middle of the outer side of the bonding plate 31. A screw hole 33 is opened at the top of one end of the fixing sleeve 32. A movable rod 34 is inserted into the inside of the fixing sleeve 32. Multiple limiting holes 35 are opened at equal intervals on the movable rod 34. The limiting holes 35 correspond to the screw holes 33. A limiting screw 36 is connected through the screw hole 33. The limiting screw 36 is adapted to the limiting hole 35. A protruding plate 37 is fixed to one end of the movable rod 34. Both sides of the protruding plate 37 are fixed to the movable rod 34 through reinforcing plates 38 to increase the connection strength between the protruding plate 37 and the movable rod 34.

[0030] More specifically, the connector 4 is located at the end of the upper support 3 away from one of the protective plates 1, and is used to connect the upper support 3 to the other protective plate. The connector 4 includes a mating block 41 located on the other side of the protruding plate 37. A fixed adjusting rod 42 and a movable adjusting rod 43 are provided between the mating block 41 and the protruding plate 37. The fixed adjusting rod 42 and the movable adjusting rod 43 are configured as a cross structure and are movably connected by a movable pin.

Then, the limiting screw 36 is turned until the limiting screw is turned. 36 passes through the corresponding limiting hole 35 to limit the movable rod 34 and the fixed sleeve 32. Then, turn the knob 53. The knob 53 drives the screw 54 to rotate. The screw 54 drives the dovetail slider 51 to move in the dovetail groove 52. The dovetail slider 51 drives the movable plate 44 to move. The movable plate 44 drives the movable adjusting rod 43 to rotate. The movable adjusting rod 43 and the fixed adjusting rod 42 cooperate to drive the bonding block 41 to move until the bonding block 41 contacts and presses against another protective plate 1. At this time, the upper support 3 cooperates with the adjusting part 5 to press and limit the upper ends of the two protective plates 1, so that the two protective plates 1 are tightly attached to the inner walls of both sides of the pit. The two protective plates 1 cooperate to play a supporting role and prevent the pit from collapsing.
