Specific embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the attached drawings here can be arranged and designed in various different configurations.

[0027] Please refer to Figures 1 to 4 As shown, an assembled edge and airside safety guardrail includes a plurality of installation columns 100, connection components 110, and a guardrail plate 130. The installation column 100 includes a fixed column 150 and a fixed base 170 installed at the bottom of the fixed column 150. The fixed base 170 is provided with a plurality of waist-shaped holes 171, and a plurality of limiting pieces 173 are slidably connected to the fixed base 170.

[0028] When installing the safety guardrail on the construction bridge, the construction workers need to first place an installation column 100 at the starting point of the safety guardrail installation location, and then slide the limiter 173 according to the spacing of the pre-buried steel bars in the bridge, so that the steel bars can smoothly pass through the waist-shaped hole 171 and the limiter 173. Then, the guardrail plate 130 is connected to the above-mentioned fixed installation column 100 through the connecting assembly 110, and finally another installation column 100 is installed according to the above steps, and the guardrail plate 130 is connected to the installation column 100, and the installation work of a set of safety guardrails can be completed.

[0029] It should be noted that in order to enable the fixed base 170 to be firmly connected to the steel bars, in this embodiment, four waist-shaped holes 171 are provided, and the angle between two adjacent waist-shaped holes 171 is 90°. Four limiting members 173 are also provided, which are respectively located above the four waist-shaped holes 171 and are all slidably connected to the fixed base 170.

[0030] The provision of the waist-shaped hole 171 and the sliding connection between the stopper 173 and the fixed base 170 increase the fault tolerance of the mounting column 100, so that the mounting column 100 can be fixed on steel bars at different intervals.

[0031] Specifically, the fixed base 170 includes a plurality of guide plates 176 and a fixed base 175, wherein the plurality of guide plates 176 are arranged around the outer periphery of the fixed base 175, and the waist-shaped holes 171 are provided on the guide plates 176. The guide plates 176 increase the contact area between the mounting column 100 and the ground, thereby providing support for the mounting column 100.

[0032] A guide groove 177 is provided on the upper end surface of the guide plate 176 along the length direction of the waist-shaped hole 171 , and the lower end of the limiting member 173 is embedded in the guide groove 177 , and the limiting member 173 can move along the length direction of the guide groove 177 .

[0033] The limiting member 173 includes a sliding plate 178 and a limiting cylinder 179. The lower end of the limiting cylinder 179 is fixedly mounted on the sliding plate 178. The sliding plate 178 is provided with an avoidance hole coaxial with the limiting cylinder 179. A plurality of steel bars sequentially pass through the corresponding waist-shaped holes 171, the avoidance holes and the limiting cylinder 179, thereby fixing the fixed base 170 on the steel bars, and the fixed base 170 cannot move or tilt in the horizontal direction; moreover, in the absence of external force, the mounting column 100 cannot move upward along the height direction of the steel bars under its own gravity.

[0034] Due to the different specifications of steel bars, the limit piece 173 in this embodiment is provided with a variety of specifications, the difference between which lies in the inner hole diameter of the limit cylinder 179. During installation, construction personnel need to select a limit cylinder 179 that matches the diameter of the steel bar to prevent the fixed base 170 from moving a short distance in the horizontal direction.

[0035] In addition, since the limiting cylinder 179 has a certain height, when the installation column 100 is subjected to a horizontal thrust, the stress surface between the limiting cylinder 179 and the steel bar is large, the limiting cylinder 179 and the steel bar are not easily bent, and the limiting cylinder 179 cannot be separated from the steel bar, thereby improving the ability of the installation column 100 to withstand the horizontal thrust and making the safety guardrail safer.

[0036] Preferably, a fixing member is screwed on the sliding plate 178. The lower end of the fixing member extends to the bottom of the sliding plate 178 and can abut against the upper end surface of the guiding plate 176. In this embodiment, the fixing member is a screw. When the lower end of the fixing member abuts against the upper end surface of the guiding plate 176, the sliding plate 178 cannot move on the guiding plate 176, thereby further enhancing the connection strength between the fixed base 170 and the steel bar.

[0037] Preferably, a cylindrical rotating seat 172 is provided on the fixed seat 175. An annular limiting groove 174 is formed on the outer periphery of the rotating seat 172. A receiving cavity 151 adapted to the shape and size of the rotating seat 172 is provided at the bottom of the fixed column 150. The rotating seat 172 is located in the receiving cavity 151, and the fixed column 150 can rotate on the rotating seat 172.

[0038] A limiting column 153 is provided at the lower part of the fixed column 150. The limiting column 153 can move along the radial direction of the fixed column 150. One end of the limiting column 153 located inside the fixed column 150 extends into the limiting groove 174. The limiting column 153 can prevent the rotating seat 172 from separating from the fixed column 150. In this embodiment, the limiting column 153 is an existing bolt, and the limiting column 153 is screwed to the fixed column 150.

[0039] During the actual construction process, the embedding of the steel bars may deviate and not be in a straight line. At this time, the construction personnel can rotate the fixed base 170 so that at least two steel bars are connected to the fixed base 170 and ensure that multiple guardrail plates 130 are on the required path.

[0040] Furthermore, the connecting assembly 110 includes at least three U-shaped connecting members 111 and a clamping member 113. The three U-shaped connecting members 111 are in the same horizontal plane and are spaced apart on the fixed column 150.

[0041] The snap-in part 113 is welded to one side of the guardrail plate 130. A snap-in groove is formed in the snap-in part 113, and the width of the snap-in groove is adapted to the thickness of a single side of the U-shaped connecting part 111. The snap-in part 113 is snap-connected to the U-shaped connecting part 111. In this embodiment, two sets of connecting components 110 are provided, and the two sets of connecting components 110 are arranged at intervals along the height direction of the fixed column 150, so that the guardrail plate 130 is more firmly connected to the fixed column 150. In this embodiment, the included angles between adjacent two U-shaped connecting parts 111 are 90°, 90° and 180°, so that the included angle between adjacent two guardrail plates 130 can be 90° or 180°. That is, the safety guardrail provided by the present invention can be installed in a straight line or surrounded into a rectangular shape.

[0042] Further, the guardrail plate 130 includes an outer frame 131 and a plurality of stabilizing rods 133. A protective net 135 is welded to one side of the outer frame 131. Both ends of the stabilizing rod 133 are welded to the outer frame 131, and a display board 137 for pasting precautions is arranged on the stabilizing rod 133. When the installed guardrail plate 130 is surrounded into a rectangular shape, the side provided with the display board 137 needs to face outward for construction workers to view. In addition, a skirting board is arranged below the display board 137, and the skirting board is installed on the outer frame 131 and the stabilizing rod 133.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
