Description

Technical Field

[0001] The utility model belongs to the field of building construction, in particular to a building construction safety fence. Background Art

[0002] Construction refers to the process of turning a building on a design blueprint into an actual building. It covers multiple stages from foundation treatment, structure construction to interior and exterior decoration, facility installation, etc. Construction involves many professional trades, such as earthwork, concrete engineering, steel structure engineering, water and electricity installation, decoration and decoration, etc. Each link requires precise planning, professional skills and strict management to ensure the quality and safety of the project.

[0003] A Chinese utility model patent with announcement number CN220747855U discloses a construction safety management fence, including side columns, and connecting pieces are arranged on the outer walls of the side columns. The connecting pieces on adjacent side columns are located in corresponding positions. The connecting pieces include a fixing seat, a through hole longitudinally opened in the middle of the fixing seat, and side plug-in holes opened on the left and right sides of the fixing seat. The fixing seat is sleeved on the outer wall of the side column through the through hole, and the side column and the fixing seat are fixedly connected by a locking piece. When the utility model is in use, the side pull rod can be inserted into the side plug-in hole of the fixing seat, and the end of the side pull rod is locked to fix the side pull rod and the fixing seat.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the height of the side columns in the safety management fence is not convenient to adjust during use, so it is not convenient to protect construction sites at high heights, and there are certain limitations in use.

[0005] Therefore, those skilled in the art have proposed a construction safety fence to solve the problems raised by the background technology. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a construction safety fence to solve the problem that the side columns in the safety management fence in the prior art are inconvenient to adjust the height during use, making it inconvenient to protect construction sites with higher heights and having certain usage limitations.

[0007] A construction safety fence, comprising a gantry, two symmetrically arranged mounting grooves opened in the gantry, a mounting rod slidably connected in the mounting groove, a first clamping groove and a second clamping groove opened in a side wall of the mounting groove, the mounting rod being provided with a limiting assembly for limiting the mounting rod in the mounting groove, the gantry being provided with a plurality of the gantry, and the gantry being provided with a mounting assembly for assembling the gantry with other gantry;

[0008] The limit assembly includes a slide groove opened on one side of the mounting rod, a wedge block slidably connected to the slide groove, limit grooves opened at the upper and lower ends of the slide groove, a limit rod fixedly connected to the limit groove, and a limit block slidably connected to the surfaces of the two limit rods, and the two limit blocks are respectively fixedly connected to the upper and lower ends of the wedge block.

[0009] Preferably, a spring is sleeved on the surface of the limiting rod, one end of the spring is fixedly connected to one end of the limiting groove, and the other end of the spring is fixedly connected to one side of the limiting block.

[0010] Preferably, the width of the wedge block matches the width of the first slot and the second slot.

[0011] Preferably, a plurality of evenly distributed fixing rods are welded inside the gantry.

[0012] Preferably, an insertion rod is welded to the lower end of the mounting rod.

[0013] When the height of the gantry needs to be adjusted, the wedge block is pressed into the first slot and the spring is squeezed. The mounting rod is then pulled downward and the mounting rod slides in the mounting slot. When the wedge block moves to the second slot, the spring returns to its initial state. At this time, the wedge block is pushed into the second slot to fix the position of the mounting rod. The height of the gantry can be increased by facilitating the height adjustment of the gantry, which effectively improves the flexibility of use of the device. When the device is not in use, the space occupied by the device when idle can be reduced by clamping the wedge block in the first slot.

[0014] Preferably, the mounting assembly includes a limiting cylinder fixedly connected to one side of the gantry, a bolt threadedly connected to the limiting cylinder, a limiting column fixedly connected to the other side of the gantry, and a threaded hole opened in the limiting column.

[0015] Through the above technical solution, when in use, by preparing multiple gantries, moving the rear gantry to one side of the front gantry, putting the limit tube on the rear gantry on the limit column, and screwing the bolt into the threaded hole, the installation of two adjacent gantries can be completed, which is convenient for expanding the scope of use of the device.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model can complete the installation of the device by inserting the insertion rod into the ground. When the wedge block is located in the first slot, the device is in a storage state. When the gantry needs to be adjusted in terms of use height, the wedge block is pressed to push the wedge block completely into the slide slot. At this time, the spring is in a squeezed state. Then the mounting rod is pulled downward and the mounting rod slides in the mounting slot. When the wedge block moves to the second slot, the spring returns to its initial state. At this time, the wedge block is pushed into the second slot, thereby fixing the position of the mounting rod. By facilitating the height adjustment of the gantry, the use height of the device can be increased, thereby effectively improving the use flexibility of the device. When the device is not in use, the space occupied by the device when it is idle can be reduced by clamping the wedge block in the first slot.

[0018] 2. The utility model prepares multiple gantries, moves the rear gantry to one side of the front gantry, sleeves the limit cylinder on the rear gantry on the limit column, and screws the bolts into the threaded holes to complete the installation of two adjacent gantries, thereby conveniently expanding the use range of the device.
