At present, on construction sites, in order to prevent the occurrence of safety accidents, protective fences are usually set up around the construction site. However, the current building guardrails are all fixed type, and the angle cannot be adjusted. It can only be designed in advance and then installed on site, and cannot adjust the angle of the guardrail according to the actual situation, with insufficient practicability. Content of the Utility Model
[0003] In order to solve the above problems of the prior art, the utility model provides a protective fence for building engineering, which solves the problems that the angle of the existing protective fence cannot be adjusted and the practicability is insufficient.
[0004] To achieve the above object, the utility model provides the following technical solution: A protective fence for building engineering, including two columns, two cross braces II are vertically and fixedly connected to the side walls of the columns, and the two cross braces II are respectively arranged at the upper end and the lower end of the column. One end of the cross brace II is rotatably connected to the cross brace I, and the other end of the cross brace I is rotatably connected to the cross brace II on another column. A locking mechanism for preventing the cross brace I and the cross brace II from rotating is installed at the junction of the cross brace I and the cross brace II. A vertical rod is fixedly connected between the two cross braces I, and a vertical rod is fixedly connected in the middle of the two cross braces II. Several vertical rods are arranged in parallel at equal distances.
[0005] With the above structural design, the cross brace I and the cross brace II are rotatably connected, and the included angle between the two cross braces can be freely adjusted, thereby adjusting the angle between two sections of the protective fence, so that different shapes can be formed, and the use flexibility is high.
[0006] Preferably, the locking mechanism includes a limiting strip rotatably connected to one end of the cross brace II, several positioning holes equidistantly opened on the side surface of the cross brace I, the positioning holes are communicated with each other through a sliding groove, and a positioning bolt passes through the limiting strip and the positioning holes to rotatably connect the limiting strip to the cross brace I.
[0007] With the above structural design, the cooperation of the limiting strip and the positioning bolt can fix the angle of two sections of the protective fence after adjustment, making the structure of the fixed protective fence more stable.
[0008] Preferably, the positioning bolt includes a positioning rod, a telescopic spring sleeved on the positioning rod, and limiting cylinders sleeved at both ends of the positioning rod and abutting against the telescopic spring. The outer diameter of the limiting cylinder is the same as the inner diameter of the positioning hole. The limiting cylinder passes through the positioning hole and is fixedly connected with a movable column. The upper end of the movable column is fixedly connected with a button. The outer diameter of the movable column is the same as the width of the sliding groove. The diameter of the limiting cylinder is larger than the diameter of the movable column.
[0009] With the above structural design, after the operator presses the button, the telescopic spring is compressed, so that the movable column fixedly connected to the lower end of the button can move in the sliding groove. When the two sections of the guardrail are adjusted to the appropriate angle, stop pressing the button, and the limiting cylinder extends out from the positioning hole through the reset function of the telescopic spring. Since the diameter of the limiting cylinder is larger than the width of the sliding groove, the positioning bolt is fixed at the positioning hole.
[0010] Preferably, a reflective strip is installed on the side wall of the upright column.
[0011] With the above structural design, the reflective strip can reflect light at night, playing a warning role and improving the safety of vehicle driving at night.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: a guardrail for construction engineering, including two columns 4. Two cross braces 2 are vertically and fixedly connected to the side walls of the columns 4. The two cross braces 2 are respectively arranged at the upper and lower ends of the column 4. One end of the cross brace 2 is rotatably connected to the cross brace 1. The other end of the cross brace 1 is rotatably connected to the cross brace 2 on another column 4. A locking mechanism 6 for preventing the cross brace 1 and the cross brace 2 from rotating is installed at the junction of the cross brace 1 and the cross brace 2. A vertical rod 3 is fixedly connected between the two cross braces 1, and a vertical rod 3 is fixedly connected in the middle of the two cross braces 2. Several vertical rods 3 are arranged in parallel and at equal distances. The cross brace 1 and the cross brace 2 are rotatably connected, and the included angle between the two cross braces can be freely adjusted, so as to adjust the angle between two sections of guardrails, and thus different shapes can be enclosed, with high flexibility in use.
[0021] The locking mechanism 6 includes a limiting strip 61 whose one end is rotatably connected to the cross brace 2, and several positioning holes 63 equidistantly opened on the side surface of the cross brace 1. The positioning holes 63 are connected to each other through a chute 64. A positioning bolt 62 passes through the limiting strip 61 and the positioning hole 63 to rotatably connect the limiting strip 61 to the cross brace 1. The cooperation between the limiting strip 61 and the positioning bolt 62 can fix the angle after adjustment of two sections of guardrails, making the structure of the fixed guardrail more stable.
[0022] The positioning bolt 62 includes a positioning rod 621, a telescopic spring 625 sleeved on the positioning rod 621, and limiting cylinders 622 sleeved at both ends of the positioning rod 621 and abutted against the telescopic spring 625. The outer diameter of the limiting cylinder 622 is the same as the inner diameter of the positioning hole 63. The limiting cylinder 622 passes through the positioning hole 63 and is fixedly connected with a movable column 626. The upper end of the movable column 626 is fixedly connected with a button 623. The outer diameter of the movable column 626 is the same as the width of the sliding groove 64. The diameter of the limiting cylinder 622 is larger than the diameter of the movable column 626. After an operator presses the button 623, the telescopic spring 625 is compressed, so that the movable column 626 fixedly connected to the lower end of the button 623 can move in the sliding groove 64. When the two sections of the guardrail are adjusted to an appropriate angle, the operator stops pressing the button 623, and the limiting cylinder 622 extends out from the positioning hole 63 through the reset function of the telescopic spring 625. Since the diameter of the limiting cylinder 622 is larger than the width of the sliding groove 64, the positioning bolt 62 is fixed at the positioning hole 63.
[0023] A reflective strip 5 is installed on the side wall of the upright column 4. The reflective strip 5 can reflect light at night, playing a warning role and improving the safety of vehicle driving at night.
