[0018] Preferably, the limiting member is an arc-shaped protrusion extending vertically in a direction away from the first clamping member.

[0019] The technical solution of the utility model has the following advantages:

[0020] 1. The utility model provides a protective upright for a steel bar frame floor deck, by arranging an extension rod on the first clamping piece, which is threadedly connected to the upright, so that the distance between the first clamping piece and the second clamping piece can be adjusted by the thread, thereby being suitable for different clamping thicknesses.

[0021] 2. The utility model provides a protective vertical pole for steel bar frame floor decking, and the anti-slip pattern can increase the surface friction of the first clamping piece and the second clamping piece, thereby increasing the friction against the steel bar, ensuring that the first clamping piece and the second clamping piece can always maintain a firm grip on the steel bar during use of the vertical pole.

[0022] 3. The protective upright pole for reinforcing bar frame floor deck provided by the utility model is fixed by connecting the two ends of the safety rope to the pull rings on the two upright poles respectively, thereby forming safety protection through the safety rope.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The protective pole 1 for steel bar frame floor decking provided in this embodiment is used to directly fix the protective pole 1 on the steel bar of the concrete main beam, and connect the safety rope to the connection part 2 of two adjacent poles 1 for safety protection.

[0033] like Figure 1 , Figure 2As shown, a specific implementation of the protective upright pole 1 for the steel bar frame floor deck provided in this embodiment includes: an upright pole 1, a first clamping member 3 and a second clamping member 5. Among them, a plurality of connecting parts 2 for connecting with the outside are arranged on the outer peripheral surface of the upright pole 1. When in use, the safety rope is connected to the connecting parts 2 of two upright poles 1 arranged relatively spaced apart to form a fence for safety protection of personnel; a first threaded part is arranged at one end of the upright pole 1; an extension rod 4 is vertically arranged at the middle position of the first clamping member 3, and a second threaded part threadedly connected to the first threaded part is arranged on the extension rod 4; the second clamping member 5 is arranged opposite to the first clamping member 3, and a avoidance hole 6 for avoiding the extension rod 4 is arranged on the second clamping member 5. The extension rod 4 on the first clamping member 3 passes through the avoidance hole 6 on the second clamping member 5 and is connected to the upright pole 1. The second clamping member 5 is provided with a limit assembly toward the side away from the first clamping member 3, and the limit assembly is used to clamp the upright pole 1 to ensure that the upright pole 1 can always remain in a vertical state. During installation, the first clamping member 3 is arranged below the steel bar, and after the second clamping member 5 passes through the first clamping member 3, the first threaded portion of the vertical pole 1 is threadedly connected with the second threaded portion of the extension rod 4, and the two are threadedly connected to clamp and fix the steel bar. By arranging the extension rod 4 on the first clamping member 3 and threading it with the vertical pole 1, the distance between the first clamping member 3 and the second clamping member 5 can be adjusted by threading, so as to adapt to different clamping thicknesses.

[0034] like Figure 2 As shown, in this embodiment, anti-skid patterns for increasing friction are respectively provided between the opposing surfaces of the first clamping member 3 and the second clamping member 5. The anti-skid patterns can increase the surface friction of the first clamping member 3 and the second clamping member 5, thereby increasing the friction on the steel bar, ensuring that the first clamping member 3 and the second clamping member 5 can always firmly clamp the steel bar during use of the vertical pole 1. In addition, as an alternative embodiment, the anti-skid patterns may not be provided, and the distance adjustment between the first clamping member 3 and the second clamping member 5 can also be achieved.

[0035] like Figure 2 As shown, in this embodiment, the first threaded portion is a threaded hole provided at the end of the vertical pole 1, and the outer side of the extension rod 4 is provided with an external thread, and the extension rod 4 corresponds to the threaded hole of the vertical pole 1, and the extension rod 4 is screwed to the end of the vertical pole 1, so that the two are fixed by threaded connection. In addition, as an alternative embodiment, the outer side of the vertical pole 1 can be provided with an external thread, and the end of the extension rod 4 can be provided with a threaded hole corresponding thereto.

[0036] like Figure 1As shown, in this embodiment, the connection part 2 is an arc-shaped pull ring. After multiple vertical poles 1 are arranged at intervals, the two ends of the safety rope are respectively connected to the pull rings on the two vertical poles 1 to form a fixation, so that safety protection is formed by the safety rope. In addition, as an alternative embodiment, the connection part 2 can also be an annular flange arranged on the vertical pole 1, and the annular flange extends outward along the radial direction of the vertical pole 1. When viewed from the axial direction of the vertical pole 1, the annular flange is circular, and a plurality of holes are arranged on the annular flange in a circumferential array, and the safety rope is connected to the holes of the annular flange.

[0037] like Figure 1 As shown, in this embodiment, the pole 1 is a cylinder, and the cylindrical pole 1 has a better distributed load and can effectively reduce external impact. In addition, as an alternative embodiment, the pole 1 can also be set as a polygon of other shapes, such as: a three-dimensional shape, a quadrilateral, etc.

[0038] like Figure 1 As shown, in this embodiment, the diameter of the pole 1 is 4.8 cm, and the height of the pole 1 is 150 cm. At this time, the diameter and height of the pole 1 can improve the stability of the pole 1, so that its bearing capacity is higher, and the weight and length of the pole 1 are suitable, which is convenient for transportation and installation. In addition, as an alternative embodiment, those skilled in the art can adjust the diameter and height of the pole 1 according to the process, which are all within the protection range.

[0039] like Figure 2 As shown, in this embodiment, the limiting assembly is: limiting pieces symmetrically arranged on both sides of the vertical pole 1, the opposite surfaces of the limiting pieces are arc-shaped with the same diameter as the vertical pole 1, and the arc-shaped surface is attached to the outer end surface of the vertical pole 1. The lower end of the vertical pole 1 is clamped by the limiting piece to improve the stability and support capacity of the vertical pole 1, and provide a more solid support. In addition, as an alternative embodiment, the limiting assembly can also be: two bolts, which are horizontally symmetrically arranged at the upper end of the second clamping piece 5 and are threadedly connected to the second clamping piece 5. By rotating the bolts, the bolts can be driven to abut against the outer end surface of the vertical pole 1 for fixing.

[0040] like Figure 2 As shown, in this embodiment, the stopper is an arc-shaped protrusion 7 extending vertically in a direction away from the first clamping member 3, and the inner side surface of the arc-shaped protrusion 7 is in contact with the vertical rod 1, and abuts against the vertical rod 1 to provide a more solid support for the vertical rod 1. In addition, as a replaceable embodiment, the arc-shaped protrusion 7 can also slide on the upper end surface of the second clamping member 5, and after sliding, the clamping force on the vertical rod 1 can be greater. In addition, as a replaceable embodiment, the stopper can also be other shapes, such as square, rectangular, etc., as long as the opposite surfaces of the two stoppers are arc-shaped surfaces.

[0041] Installation method of the protective vertical pole 1: anti-slip grooves are provided between the opposite surfaces of the first clamping part 3 and the second clamping part 5. An extension rod 4 is vertically extended upward from the upper end face of the first clamping part 3. The extension rod 4 is cylindrical and a thread is provided on the outside of the extension rod 4. The lower end of the vertical pole 1 is threadedly connected with the extension rod 4. An avoidance hole 6 is provided in the middle position of the second clamping part 5. The extension rod 4 is connected to the vertical pole 1 after passing through the avoidance hole 6. During installation, the first clamping part 3 is placed below the steel mesh, and the avoidance hole 6 of the second clamping part 5 is placed above the steel mesh after passing through the extension rod 4. The vertical pole 1 is threadedly connected to the first clamping part 3, and the vertical pole 1 is located between the two limit members. When the vertical pole 1 is continuously rotated, the lower end of the vertical pole 1 abuts against the upper end face of the second clamping part 5, causing the first clamping part 3 and the second clamping part 5 to continuously approach each other and clamp the steel mesh. Afterwards, multiple vertical poles 1 are arranged at intervals on the steel mesh, and safety ropes are connected to the connecting parts 2 between two adjacent vertical poles 1 to form safety protection.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
