Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit safety protection, in particular to a foundation pit safety protection device for building construction. Background Art

[0002] In building construction, foundation pit construction is included. In foundation pit construction, a safety protection device needs to be set up to protect the internal or surrounding environment of the construction foundation pit. Most of the existing foundation pit safety protection devices are used to protect the periphery of the foundation pit. However, the soil inside the foundation pit is loose and prone to collapse over time. A support device that can adapt to the slope of the foundation pit and be continuously assembled is required. Moreover, when an operator works inside the foundation pit, if stones on the top of the foundation pit slide down, the operator is easily injured.

[0003] The patent with the publication number of CN210797574U discloses a safety protection device for a road foundation pit in construction, including a first protection top plate and a second protection top plate. The inner sides of the bottoms of the first protection top plate and the second protection top plate are both slidably and embeddedly connected with a protection bottom plate. The two ends of the tops of the first protection top plate and the second protection top plate and the two ends of the bottoms of the two protection bottom plates are symmetrically and rotatably connected with second threaded rods. And the adjacent ends of the two second threaded rods are both spirally and embeddedly connected with second internal threaded pipes. And the adjacent ends of the two second internal threaded pipes are respectively rotatably connected with the two ends of a connection card. The inner sides of the first protection top plate and the second protection top plate are both rotatably connected with a falling prevention net.

[0004] The above-mentioned foundation pit safety protection device can adjust the protection height according to the depth of the foundation pit, so that the protection device can be applicable to foundation pits with different depths. However, the protection plate needs to be supported by the cooperation of the connection card and the second internal threaded pipe. That is, the above-mentioned foundation pit safety protection device can only be applicable to foundation pits with a smaller width. When the width of the foundation pit is larger, the protection plate has no stable support and is prone to tipping over, affecting the safety of construction. Content of the Utility Model

[0005] The utility model provides a foundation pit safety protection device for building construction, which solves the problem that the existing foundation pit safety protection device is not applicable to foundation pits with a larger width in the prior art.

[0006] The technical solution of the utility model is realized as follows:

[0007] A safety protection device for foundation pits in construction includes a base plate. One side of the base plate is connected to a support base, and the other side of the base plate is rotatably connected to a protective slope plate. An anti-falling mechanism is provided on the protective slope plate, a slope adjustment mechanism is provided between the bottom support assembly and the protective slope plate, and an anchoring assembly for connecting to the side wall of the foundation pit is provided on the protective slope plate. The slope adjustment mechanism can adjust the inclination angle of the protective slope plate, so that the protection device can be applied to foundation pits with different side wall inclination angles, enhancing the applicability of the protection device. At the same time, the anchoring assembly can enhance the connection strength between the protective slope plate and the side wall of the foundation pit, ensuring the stability of the protective slope plate during use; the anti-falling mechanism intercepts and collects falling stones and other rolling objects, preventing the rolling objects from falling into the foundation pit and injuring the workers, effectively ensuring the personal safety of the workers.

[0008] The slope adjustment mechanism includes a lower fixing piece and an upper fixing piece. The lower fixing piece is connected to the support base, and the upper fixing piece is connected to the protective slope plate. The lower fixing piece and the upper fixing piece are hinged and connected by a jack. The telescopic movement of the jack changes the distance between the lower fixing piece and the upper fixing piece, thereby changing the inclination angle of the protective slope plate.

[0009] The anti-falling mechanism includes a telescopic plate. The telescopic plate is slidably arranged on the protective slope plate. A limiting component is provided between the telescopic plate and the protective slope plate. A baffle is provided at the top of the telescopic plate. Columns are connected to the four sides of the top surface of the baffle, and a retaining net is arranged on the side surface of the columns. The columns support the retaining net. When the rolling object falls onto the baffle, it is intercepted by the retaining net, preventing the rolling object from falling off the baffle and further preventing the rolling object from falling into the foundation pit.

[0010] The limiting component includes a limiting hole and a limiting bolt. The limiting hole is arranged on one side of the protective slope plate, and the limiting bolt is threadedly connected to the limiting hole. The limiting bolt passes through the limiting hole and cooperates with the telescopic plate. After the relative position of the telescopic plate and the protective slope plate is adjusted, the limiting bolt is rotated so that the limiting bolt is connected to the telescopic plate, thereby fixing the relative position of the telescopic plate and the protective slope plate and ensuring the stability of the telescopic plate during use.

[0011] The support base includes channel steel plates connected to both ends of the base plate. An adjusting plate is provided between the two channel steel plates. Anchoring holes are provided on the adjusting plate, and grounding cones are arranged in the anchoring holes; the lower fixing piece is arranged on the adjusting plate. The grounding cones pass through the adjusting plate and are inserted into the ground to fix the support base on the ground. The grounding cones play a role in facilitating the fixation of the protection device, improving the stability of the protection device.

[0012] The anchoring assembly includes positioning bolts arranged on the protective slope plate. The positioning bolts pass through the protective slope plate and are connected to the side wall of the foundation pit. The positioning bolts are inserted into the side wall of the foundation pit to form a connection between the protective slope plate and the side wall of the foundation pit, ensuring the stability of the protective slope plate.

[0013] On both sides of the slope protection plate, a left connection mechanism and a right connection mechanism are respectively provided, and the left connection mechanism on the slope protection plate is detachably connected to the right connection mechanism on the adjacent slope protection plate.

[0014] The left connection mechanism includes a left rotating member arranged on one side of the slope protection plate. A left rotating rod is rotatably connected to the left rotating member, and a left plug-in member is rotatably connected to the end of the left rotating rod.

[0015] The right connection mechanism includes a right rotating member arranged on the other side of the slope protection plate. A right rotating rod is rotatably connected to the right rotating member, and a right insertion sleeve is rotatably connected to the end of the right rotating rod. The right insertion sleeve is in plug-in fit with the left plug-in member, and through threaded holes are provided on the left plug-in member and the right insertion sleeve, and a through threaded column is connected in the through threaded holes.

[0016] A water seepage mesh is provided at the lower part of the slope protection plate. The water flowing into the foundation pit along the side wall of the foundation pit flows out from the water seepage mesh. The water seepage mesh can intercept soil, sundries, etc., and prevent the water from flushing the soil into the foundation pit.

[0017] The beneficial effects produced by the present utility model are as follows: 1. The slope adjustment mechanism can adjust the inclination angle of the slope protection plate, so that the protection device can be applicable to foundation pits with different side wall inclination angles, enhancing the applicability of the protection device. At the same time, the anchoring assembly can enhance the connection strength between the slope protection plate and the side wall of the foundation pit, ensuring the stability of the slope protection plate during use.

[0018] 2. For the foundation pit safety protection device for building construction, through the setting of the anti-falling mechanism, the telescopic plate is pulled out to an appropriate length and the limit bolt is tightened. When stones roll down outside the foundation pit, the provided retaining net intercepts the rolling objects such as stones, avoiding injury to the construction personnel inside the foundation pit and improving the safety of the device.

[0019] 3. For the foundation pit safety protection device for building construction, through the comprehensive setting of the slope adjustment mechanism, the left connection mechanism and the right connection mechanism, the device is placed at a suitable position on the bottom edge of the foundation pit, the grounding cone is tightened, and at the same time the jack is pressed, so that the slope protection plate rotates and fits inside the foundation pit for support, and the positioning bolt is tightened for fixation. At the same time, the left plug-in member of another set of protection devices is inserted into the right insertion sleeve, and the through threaded column is tightened, and then the above steps are repeated for assembly, so that the protection device is adapted to different foundation pits for safety protection, improving the applicability of the device.
