Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding foundation devices, in particular to an adjustable anti-slip external scaffolding foundation device for slope sections. Background Art

[0002] Due to the non-standard construction of scaffolding, frequent collapse accidents occur, which not only cause serious casualties and economic losses, but also seriously hinder the healthy and sustainable development of the construction industry in China. In some sites with poor actual conditions, it is necessary to erect a scaffolding on a slope.

[0003] When erecting an external scaffold on a slope, if the foundation is set improperly, it often changes the stress form at the bottom of the vertical pole (surface load becomes point load), resulting in uneven stress on the vertical pole, increased concentrated stress, and easy deformation. Moreover, as the slope increases, the potential safety hazards of the external scaffold also increase, and safety problems such as local deformation of members, slip of the scaffold body, and even instability may occur.

[0004] Based on this, those skilled in the art proposed an adjustable anti-slip external scaffolding foundation device for slope sections. Content of the Utility Model

[0005] The utility model discloses an adjustable anti-slip external scaffolding foundation device for slope sections, aiming to solve the technical problems in the background art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An adjustable anti-slip external scaffolding foundation device for slope sections, including a slope body and a fixed base. The slope body is the slope section for erecting the external scaffold. A concrete hardening layer is provided at the top of the slope body. The top of the concrete hardening layer is the external scaffolding body. Channel steels are provided at the slope section of the concrete hardening layer. Anti-slip inserting plates are fixedly connected to the bottom of the channel steels at equal intervals, and the anti-slip inserting plates all extend into the interior of the concrete hardening layer;

[0008] Two rotating bearings are symmetrically and rotatably connected inside the fixed base. A rotating plate is rotatably connected between the corresponding two rotating bearings. A connecting rod is fixedly connected to the top of the rotating plate, and the connecting rods all extend to the bottom of the vertical pole of the corresponding scaffold body.

[0009] During actual use, first use a vibrating roller or a rammer to flatten and tamp the entire slope body, and then carry out positioning and setting out. At this time, brackets should be used and fixed, and the brackets are used to support and fix the channel steels. Then, pour a concrete hardening layer on the slope body and level the surface. The poured concrete fills the bottom of the channel steel and does not exceed the thickness of the web of the channel steel, so that the anti-slip inserting plates fixedly connected to the bottom of the channel steel at equal intervals are completely buried in the concrete hardening layer.

[0010] In a preferred embodiment, a rotating shaft is rotatably connected inside the fixed base, a lead screw is fixedly connected to the rotating shaft, an adjustment slot is formed on the rotating plate, and the top of the lead screw extends above the rotating plate through the adjustment slot.

[0011] Adjust the rotating plate, and the lead screw rotates through the adjustment slot until the connecting rod is in a vertical state.

[0012] In a preferred embodiment, two adjusting nuts are threadedly connected to the outside of the lead screw and below the rotating plate, and a limiting nut is threadedly connected to the outside of the lead screw and above the rotating plate.

[0013] Turn the adjusting nut so that the adjusting nut contacts the bottom of the rotating plate. Then, screw another adjusting nut to one side of the other adjusting nut to limit the uppermost adjusting nut. Then, turn the limiting nut to make it contact the rotating plate, thereby limiting the rotating plate, and finally keeping the lead screw perpendicular to the rotating plate and firmly fixed.

[0014] In a preferred embodiment, two locking screws are symmetrically and threadedly connected to the outside of the fixed base. Contact disks are rotatably connected to the closer ends of the two locking screws, and locking nuts are threadedly connected to the outside of the locking screws.

[0015] Install the fixed base on the channel steel, and then use the locking screws to make the contact disks abut against the channel steel, so that the fixed base can be connected to the channel steel. Then, tighten the locking nuts to connect the entire fixed base to the channel steel.

[0016] In a preferred embodiment, the farther ends of the two locking screws are both provided with an external hexagonal structure.

[0017] With such a setting, it is convenient for the user to turn the locking screw.

[0018] In a preferred embodiment, the framework is an external scaffolding formed by vertical poles, bottom-sweeping poles and cross bars.

[0019] With such a setting, it is convenient for the framework to cooperate with the connecting rod, and at the same time, the weight of the framework can be reduced.

[0020] The adjustable anti-slip external scaffolding foundation device for slope sections provided by the present utility model has the following advantages:

[0021] The fixed base of this device can be adjusted arbitrarily along the direction of the channel steel to meet the requirements of different vertical rod spacings of the framework. By rotating the rotating plate to drive the rotation of the connecting rod, the device can be adjusted and leveled according to the slope, that is, converting the inclined foundation of the vertical rod into a horizontal foundation, avoiding uneven stress at the bottom of the vertical rod. The design of the connecting screw rod ensures that the vertical rod does not shift, and it is suitable for the erection of scaffolding on slope sections with different slopes. The anti-slip insert plate ensures the anti-slip ability of the channel steel, while the locking screw rod guarantees the anti-slip performance of the fixed base. Description of the Drawings
