Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a foundation pit supporting frame. Background Art

[0002] The foundation pit is one of the most important links in building construction. The structural strength of the foundation pit is closely related to the stability of the building. Therefore, when constructing the foundation pit, in order to prevent the foundation pit from collapsing, support frames are usually used to fix the side walls of the foundation pit to avoid the problem of foundation pit collapse during construction.

[0003] When installing the existing support frame, several triangular supports and the side walls of the foundation pit are usually fixed to each other, and then several side rails are placed on the triangular supports, and the several side rails and the side walls of the foundation pit are driven to contact each other. In order to improve the stability and firmness of the side rails, the staff usually use bolts to splice the several side rails to each other. The several side rails can support the side walls of the foundation pit and prevent the side walls of the foundation pit from collapsing. After the side rails are spliced, the several support rods and the side rails are installed to each other with bolts again. While improving the supporting effect of the side rails, it can also prevent the side rails from deformation. After the support rods and the side rails are fixed, the foundation pit is excavated and the above operations are repeated to complete the installation of the support frame.

[0004] However, when the support frame is spliced, tools are needed to insert several bolts into the reserved holes one by one. The installation process is too cumbersome and it is inconvenient to disassemble the support frame, which affects work efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0007] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a foundation pit support frame, including a surrounding rail and a plurality of support rods and a triangular bracket connected to each other, the surrounding rails are provided with a plurality of mounting holes, and mounting rods are slidably connected in the plurality of mounting holes, one end of the mounting rod is fixedly connected with a fixing plate 1, and the other end is detachably connected with a fixing plate 2, the fixing plate 2 and the mounting rod are clamped to each other through a clamping assembly, the fixing plate 1 and the fixing plate 2 are respectively fitted with the surrounding rails, and the plurality of support rods and the surrounding rails are connected through a mounting assembly.

[0008] By adopting the above technical scheme, when installing the support frame, the triangular bracket and the side wall of the foundation pit are installed to each other, and then a plurality of enclosures are placed on the plurality of triangular brackets, and the plurality of enclosures are driven to contact each other at the same time, and then the installation rod is inserted into the installation hole on the plurality of enclosures, and the fixing plate 1 on the installation rod and the plurality of enclosure side walls are driven to fit each other, and then the fixing plate 2 and the installation rod are clamped to each other through the clamping assembly. At this time, the plurality of enclosures are restricted by the installation rod and the fixing plate 1 and the fixing plate 2, so that the plurality of enclosures cannot be separated from each other, thereby achieving the effect of splicing the plurality of enclosures. After the plurality of enclosures are installed, the support rod and the enclosure can be connected to each other through the installation assembly, thereby completing the effect of installing the support frame. By setting the clamping assembly and the installation assembly, when installing the support frame, the support frame can be installed without using bolts, which reduces the steps of installing the support frame and can also facilitate the disassembly of the support frame, thereby improving work efficiency.

[0009] The utility model is further configured as follows: the clamping assembly includes two clamping blocks, the mounting rod is provided with a sliding groove for the two clamping blocks to slide, the mounting rod is provided with a driving member for driving the two clamping blocks to slide, the fixed plate 2 is provided with a through groove for the mounting rod to slide, and when the fixed plate 2 and the clamping blocks are clamped with each other, the fixed plate 2 and the surrounding plate fit each other.

[0010] By adopting the above technical solution, when the fixing plate 2 and the mounting rod are engaged with each other, the fixing plate 2 is placed at the bottom of the mounting rod, and then the mounting rod is driven to start sliding along the side wall of the through groove, and at the same time, the fixing plate 2 and the side wall of the surrounding wall are driven to fit each other, and then the two clamping blocks are driven by the driving member to move along the sliding groove to the outside, and engage with each other at the bottom of the fixing plate 2. At this time, the fixing plate 2 is affected by the two clamping blocks and cannot move again, so that the fixing plate 2 and the side wall of the surrounding wall are fixed to each other, thereby achieving the effect of mutually engaging the fixing plate 2 and the mounting rod.

[0014] By adopting the above technical scheme, when it is necessary to install the support rod, several installation frames are placed on the enclosure, and then the support rod is pushed to drive the installation frame to move on the enclosure. After the installation frame is moved to the specified position, the moving rod is driven by the cylinder to start moving in the direction of the enclosure, and at the same time, the moving rod and the side wall of the enclosure are driven to abut against each other, and then the moving rod is continued to be driven to move. At this time, the support rod is affected by the moving rod and also abuts against the side wall of the enclosure. At this time, the support rod and the moving rod are restricted by the adjusting part and cannot move, thereby achieving the effect of installing the support rod and the enclosure to each other. When it is necessary to disassemble the support rod, it is only necessary to drive the moving rod back to its original position by the cylinder. At this time, the moving rod and the support rod are respectively no longer abutted against the side wall of the enclosure, which facilitates the disassembly of the support rod and improves work efficiency.

[0015] The utility model is further configured as follows: the side wall of the moving rod is fixedly connected with a connecting plate, and the connecting plate and the inner side wall of the regulating box are slidably connected and fit each other.

[0016] By adopting the above technical solution, it is possible to avoid the position of the moving rod from being offset when the moving rod moves, thereby improving the stability of the moving rod when moving.

[0017] The utility model is further configured as follows: one end of the support rod and the moving rod is fixedly connected to a limiting plate.

At the same time, since the two sides of the cross section of the adjusting rod 11 are inclined, when the adjusting rod 11 moves, the diameter of the contact point between the two blocking blocks 8 and the adjusting rod 11 will gradually increase. At this time, the two blocking blocks 8 will be affected by the adjusting rod 11 and start to move outward along the slide groove 9 and engage with each other at the bottom of the fixed plate 27. At this time, the fixed plate 27 is affected by the two blocking blocks 8 and cannot move again, so that the fixed plate 27 and the side walls of the enclosure 1 are fixed to each other, thereby achieving the effect of mutual engagement of the fixed plate 27 and the mounting rod 5.
