Description

Technical Field

[0001] The present application relates to the technical field of foundation pit support, and specifically to a foundation pit support equipment. Background Art

[0002] A foundation pit is a pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. When constructing underground projects such as foundation pits, the surrounding foundation and soil conditions will be damaged to a certain extent. In this case, it is necessary to build soil supports at the edge of the foundation pit and then reinforce the side walls of the foundation pit to ensure the safety of the foundation pit and its surrounding environment.

[0003] When the existing foundation pit support frame is in use, the support rod in the middle of the support frame is welded to the support plates on both sides, which makes it inconvenient to adjust the width of the support frame as a whole and inconvenient to support foundation pits of different sizes. Moreover, the support frame is welded as a whole, which is inconvenient to install and disassemble.

[0004] Therefore, there is an urgent need for a foundation pit support equipment to solve the problem that the overall width of the support frame is inconvenient to adjust. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides a foundation pit support device that has the advantage of conveniently adjusting the width of the middle rod of the support frame, thereby solving the problem of inconvenient adjustment of the overall width of the support frame.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a foundation pit support device, comprising a support plate, a fixing mechanism provided at the bottom of the support plate, a supporting mechanism provided at the bottom of the support plate, and two groups of the support plates connected by the supporting mechanism;

[0007] The support mechanism includes a threaded sleeve, a threaded rod, a connecting column, a support block and a fixed seat. The two groups of threaded rods are respectively threadedly connected to the two ends of the threaded sleeve. The other end of the threaded rod is welded to the inner side of the connecting column. The support block is fixedly connected to the inner side of the support block by a screw. The support block is rotatably connected to the fixed seat through a rod. The fixed seat is welded to the inner side of the support plate.

[0008] By changing the width of the support frame, the support frame can be used to conveniently protect foundation pits of different widths. At the same time, when the support frame is unloaded, the construction workers can remove the screws between the connecting column and the support block, so that the support mechanism can be easily separated from the support plate, making it easier to install and disassemble the support frame.

[0009] Preferably, a rubber sleeve is bonded to the middle position of the threaded sleeve.

[0010] Preferably, the thread directions of the two groups of threaded rods are opposite.

[0011] Preferably, the fixing seat is a block with a U-shaped structure.

[0012] Preferably, the fixing mechanism includes a base, an insertion rod and a protrusion. The base is rotatably connected to the bottom of the support plate through a rod. The insertion rod passes through the plate body on the inner side of the base. The three groups of protrusions are welded to the outer surface of the insertion rod.

[0013] Preferably, the three groups of insertion rods are located on the inner side of the base and are distributed linearly.

[0014] In summary, this application has at least one of the following beneficial effects:

[0015] 1. When the support frame of the foundation pit support equipment is installed to the inner side of the foundation pit, by adjusting the length of the extended threaded rod, when the two sets of threaded rods extend outward, the two sets of support plates can be driven to move outward, thereby changing the width of the support frame, so that the support frame can conveniently protect foundation pits of different widths. At the same time, when the support frame is unloaded, the construction workers can remove the screws between the connecting column and the support block, so that the support mechanism can be easily separated from the support plate, which is convenient for the installation and disassembly of the support frame.

[0016] 2. For this foundation pit support equipment, when the support frame is installed inside the foundation pit, the staff can push the support plate, and the support plate rotates on the top of the base, so that the support frame can protect foundation pits with different inclinations. At the same time, the rod passes through the base and is inserted into the soil to fix the base, so that the support frame can be more stable during installation and the support frame can be used more conveniently.

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] See also Figure 1-4 A foundation pit support device includes a support plate 1, a fixing mechanism is provided at the bottom of the support plate 1, a supporting mechanism is provided at the bottom of the support plate 1, and two groups of support plates 1 are connected by the supporting mechanism.

[0024] Through the above technical solution, when the support frame is installed to the inside of the foundation pit, the support plate 1 can protect and reinforce the inside of the foundation pit so that both sides of the foundation pit will not collapse. The support mechanism can support the two groups of support plates 1, so that the support plates 1 can stably protect the foundation pit.

[0025] Specifically, the supporting mechanism includes a threaded sleeve 111, a threaded rod 112, a connecting column 113, a support block 114 and a fixed seat 115. The two groups of threaded rods 112 are respectively threadedly connected to the two ends of the threaded sleeve 111, and the other end of the threaded rod 112 is welded to the inner side of the connecting column 113. The thread directions of the two groups of threaded rods 112 are opposite. The support block 114 is fixedly connected to the inner side of the support block 114 by screws. The support block 114 is rotatably connected to the fixed seat 115 through a rod. The fixed seat 115 is welded to the inner side of the support plate 1. The fixed seat 115 is a U-shaped block. A rubber sleeve 116 is bonded to the middle position of the threaded sleeve 111.

[0026] Through the above technical solution, when the support frame is installed to the inside of the foundation pit, the staff can rotate the rubber sleeve 116, and the rubber sleeve 116 drives the threaded sleeve 111 to rotate. When the threaded sleeve 111 rotates, it drives the threaded rod 112 to extend or shorten. When the threaded rod 112 extends, it can drive the two groups of support plates 1 to move outward, changing the width of the support frame, so that the support frame can conveniently protect foundation pits of different widths. At the same time, when the support frame is unloaded, the construction personnel can remove the screws between the connecting column 113 and the support block 114, so that the support mechanism can be easily separated from the support plate 1, which is convenient for the installation and disassembly of the support frame.

[0027] Specifically, the fixing mechanism includes a base 211, an insertion rod 212 and a protrusion 213. The base 211 is rotatably connected to the bottom of the support plate 1 through a rod. The insertion rod 212 passes through the plate body inside the base 211. Three groups of protrusions 213 are welded to the outer surface of the insertion rod 212. The three groups of insertion rods 212 are located on the inner side of the base 211 and are linearly distributed.

[0028] Through the above technical solution, when the support frame is being installed, the construction workers can push the support plate 1, and the support plate 1 rotates on the top of the base 211, so that the support frame can protect foundation pits with different inclinations. At the same time, the insertion rod 212 passes through the base 211 and is inserted into the soil to fix the base 211, so that the support frame can be more stable during installation, making the support frame more convenient to use.

[0029] During use, by changing the width of the support frame, the support frame can be used to conveniently protect foundation pits of different widths. At the same time, when the support frame is unloaded, the construction workers can remove the screws between the connecting column 113 and the support block 114, so that the support mechanism can be easily separated from the support plate 1, which facilitates the installation and disassembly of the support frame.

[0030] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
