Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, and more specifically, to a foundation pit supporting structure. 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, the baffle is usually abutted against the side wall of the foundation pit, and then the baffle and the foundation pit are fixed to each other using tools, and then several support columns are installed between the two baffles. The baffle is further reinforced by the support columns to complete the installation of the support frame. The setting of the baffle can effectively prevent the foundation pit from collapsing.

[0004] However, when excavating a foundation pit, the angle of the side wall of the foundation pit depends on the engineering design requirements and geological conditions, so the angle of the side wall of the foundation pit will be different. As a result, when the baffle on the support frame is installed on the side wall of the foundation pit, a gap is easily generated between the baffle and the side wall of the foundation pit, affecting the support effect of the foundation pit.

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

[0006] In view of the shortcomings of the existing technology, the purpose of the present utility model is to provide a foundation pit support structure, which solves the problem that when the baffle on the support frame is installed on the side wall of the foundation pit, a gap is easily generated between the baffle and the side wall of the foundation pit, thereby affecting the support effect of the foundation pit.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: a foundation pit support structure, including a plurality of baffles and a plurality of support columns, a plurality of baffle side walls are provided with a slide groove, a moving block is slidably connected in the slide groove, an adjustment plate is hingedly provided on the moving block, a driving assembly for driving the moving block to move is provided on the baffle, and the adjustment plate and the baffle are connected by an adjustment assembly to adjust the angle between the baffle and the adjustment plate.

[0008] By adopting the above-mentioned structural setting, when installing the support frame, the baffle is fixed to the side wall of the foundation pit, and then the driving assembly drives the moving block to move downward along the slide groove, and at the same time the moving block drives the adjustment plate to move toward the inclined part of the side wall of the foundation pit. When the adjustment plate moves to the inclined part of the foundation pit, the angle between the baffle and the adjustment plate is adjusted by the adjustment assembly, and the adjustment plate and the inclined part of the side wall of the foundation pit are driven to contact and fix each other, and finally the support column is installed between the two baffles to complete the installation of the support frame. Through the setting of the adjustment plate, the baffle can effectively reduce the gap between the baffle and the foundation pit when it is installed with the side wall of the foundation pit, thereby improving the support effect of the foundation pit.

[0009] The utility model is further configured as follows: the driving assembly includes a hydraulic cylinder fixedly connected to the side of the baffle away from the adjustment plate, the output end of the hydraulic cylinder is fixedly connected to a connecting plate, the connecting plate and the moving block are fixedly connected by a plurality of connecting blocks, and the baffle is provided with a plurality of through grooves for the connecting blocks to slide.

[0012] By adopting the setting of the above-mentioned adjustment component, when it is necessary to adjust the angle between the baffle and the adjustment plate, the electric push rod is started, and the output end of the electric push rod is driven to drive the limiting plate to move downward along the inner side of the fixed frame. At the same time, since the limiting plate and the adjustment plate are connected by the magnetic layer, the limiting plate and the adjustment plate always maintain contact. At this time, the adjustment plate is affected by the limiting plate, causing the adjustment plate to rotate, thereby achieving the effect of adjusting the angle between the baffle and the adjustment plate.

[0013] The utility model is further configured as follows: the limiting plate is configured in an arc shape on a side close to the magnetic attraction layer.

[0014] By adopting the above-mentioned shape setting, the contact area between the adjustment plate and the limiting plate can be increased, thereby improving the fixing effect between the limiting plate and the adjustment plate.

[0016] By adopting the above-mentioned structural setting, when the adjusting plate and the inclined part of the foundation pit side wall are brought into contact with each other, pressure is applied to the connecting rod, driving the connecting rod to drive the wedge block to move. At the same time, the movable plate is affected by the inclined surface of the wedge block and begins to move toward the outside along the side wall of the placement groove, and a number of fixed teeth on the movable plate are inserted into the foundation pit. By setting a number of fixed teeth, the fixing effect between the adjusting plate and the foundation pit can be further increased, thereby improving the support effect of the foundation pit.

[0017] The utility model is further configured as follows: one end of the connecting rod away from the wedge block is fixedly connected to the limiting plate.

[0018] By adopting the setting of the above-mentioned limiting plate, it is possible to prevent the connecting rod from completely entering the placement groove, resulting in an effect that the connecting rod cannot be taken out, thereby avoiding affecting normal use.

[0019] The utility model is further configured as follows: a support plate is fixedly connected to the bottom of the baffle, the bottom of the hydraulic cylinder and the support plate are in contact with each other, and a plurality of support rods are fixedly connected between the baffle and the support plate.

[0020] By adopting the above-mentioned support plate arrangement, the supporting effect of the baffle in the foundation pit can be improved, the compressive resistance of the baffle can be increased, and the supporting effect of the foundation pit can be improved.

[0021] To sum up, the utility model has the following beneficial effects: when installing the support frame, the driving assembly drives the moving block to move downward along the slide groove, and at the same time the moving block drives the adjustment plate to move toward the inclined part of the foundation pit side wall.
