Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a protective device for the construction of traffic civil engineering bridges. Background Technology

[0002] During bridge construction, for safety reasons, protective devices must be erected at the construction site to isolate the construction space from the outside, thereby preventing external personnel and vehicles from entering the site at will and avoiding potential safety hazards.

[0003] Patent CN223215046U discloses a protective device for road and bridge construction. In use, the protective netting is fixed to the front and rear fixing plates with bolts. A water inlet is located at the top of the base, and a limiting groove is formed inside the connecting column. The front and rear fixing plates are engaged within the limiting groove, and the connecting column is then inserted into the installation groove. Rotating the first and second rotating blocks causes the screw rod to screw into the fixing ring, thus connecting the connecting column and the installation groove. Finally, the support column and the base are connected with fixing bolts. However, this device has the following drawbacks: because water or sand needs to be injected into the base through the water inlet, increasing the weight of the base, gaps form between the protective netting and the ground. These gaps may pose safety hazards: unauthorized personnel (especially short individuals) may enter the construction area through the gaps, facing risks such as mechanical injury, falling objects, and even disrupting the construction process.

[0004] Therefore, how to protect the gap between the protective structure and the ground has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide a protective device for the construction of traffic civil engineering bridges to overcome the shortcomings mentioned above.

[0006] To achieve the above objectives, the technical solution of this utility model is: a construction protection device for traffic civil engineering bridges, comprising:

[0007] Each of the two fixed columns has at least one first fixing ring on its opposite sidewalls near its lower end;

[0008] The mounting frame has at least one mounting groove inside, a protective net is snapped into the mounting groove, and a first protective plate is hinged to its lower end. At least one second fixing ring is provided on the side wall opposite to the first protective plate.

[0009] A connecting plate is rotatably connected to each of the opposite sidewalls of the mounting frame. Its other end is detachably connected to a fixing post, and its lower end is hinged to a second protective plate. At least one third fixing ring is provided on each of the opposite sidewalls of the second protective plate.

[0013] Furthermore, a fixing plate is provided inside the fixing body, and the fixing plate is I-shaped and fixedly connected to the inner side wall of the fixing body.

[0014] Furthermore, the connecting plate is T-shaped, and the opposite sidewalls of the mounting frame are rotatably connected to the connecting plate via connecting components.

[0015] Furthermore, the connecting assembly includes a connecting rod and a nut. The connecting rod is T-shaped, and one end of the connecting rod is provided with a threaded section. First connecting sleeves are fixedly connected to the opposite sidewalls of the mounting frame, and a second connecting sleeve is fixedly connected to one side of the connecting plate. The first connecting sleeve and the second connecting sleeve are arranged alternately.

The receiving column is provided with a blind hole facing downward. The upper end of the receiving column is provided with a plurality of the permeable holes. At least one first fixing ring is provided on each of the opposite sidewalls of the receiving column. The lower end of the receiving column is fixedly connected to the ear plate, and the ear plate is provided with a through hole.

[0017] Furthermore, the binding element is a nylon cable tie.

[0018] Compared with the prior art, this utility model has at least the following advantages: In use, firstly, two fixed posts are erected at the designated position at the edge of the construction area as the basic support for the device. Next, the mounting frame with a protective net is placed between the two fixed posts, and the protective net is snapped into the mounting groove. Then, the connecting plates on both sides of the mounting frame are rotated so that their other ends connect to the fixed posts. Afterward, the first protective plate hinged at the lower end of the mounting frame is rotated downward to cover the gap between the mounting frame and the ground. Simultaneously, the second protective plate hinged at the lower end of the connecting plate is rotated, similarly covering the gap between the connecting plate and the ground. Finally, the first fixing ring is connected to the second fixing ring, and the second fixing ring is connected to the third fixing ring, using binding materials to form a continuous protective structure consisting of the fixed posts, the first protective plate, and the second protective plate. This fills the gap between the protective structure and the ground, preventing unauthorized personnel (especially those of short stature) from entering the construction area through the gap.
