Problems solved by technology
However, this type of guardrail has a fatal shortcoming, that is, the rigidity is too strong, and the energy absorption capacity is poor. When the vehicle collides with it, most of the energy is absorbed by the vehicle, thus causing major injuries to the vehicle and the occupants.
In addition, there are problems such as heavy quality, difficult transportation, high cost and maintenance costs, and difficult molding.

Embodiment
[0027] Example: Control Figure 1-4
[0028] An assembled polymer material guardrail includes several uprights 2, the bottom of each upright 2 is fixedly installed on the ground through a base 11, and PP horizontal pipes 10 are horizontally installed between two adjacent uprights 2. Both ends of the PP horizontal pipe 10 are connected and fixed to the sides of the column 2 in the same manner.
[0029] control Figure 4 , the column 2 is a hollow tubular structure, and the upper opening of the column 2 is fit into a column cover 1 . The base 11 includes a base plate and a spacer column arranged on the base plate. The lower opening of the column 2 is arranged and inserted on the outside of the spacer column of the base 11, and the lower end side of the column 2 and the side portion of the spacer column correspond to each other. Corresponding column threaded holes are provided, and the column 2 and the limiting column of the base 11 are connected and fixed together by using an...

The assembled high polymer material protective fence comprises a base, a stand column and a PP transverse pipe, wherein the PP transverse pipe is fixedly connected with the side portion of the stand column through a cross beam pin, and the cross beam pin comprises an inserting section and a butt joint section; a cylindrical plug hole is formed in the inserting section, and a large TPE damping piece is plugged into the cylindrical plug hole; the inserting section plugged with the large TPE damping piece is inserted into the PP transverse pipe; a cylindrical through hole in the center of the large TPE damping piece is vertically aligned with a cross beam slotting through hole in the PP transverse pipe, a cross beam slotting is arranged in a matched and penetrating mode, then the cross beam slotting is connected with a cross beam slotting cap in a matched and screwed mode, and the inserting section of the cross beam pin and the PP transverse pipe are installed and fixed in an inserting mode; the butt joint section of the cross beam pin is in butt joint with the side portion of the stand column. The assembled high polymer material protective fence is of a movable structure, and when the assembled high polymer material protective fence is stressed, the absorption capacity effect is achieved through compression damping of the TPE damping pieces and rotation of the cross beam pins. When the PP transverse pipe is impacted and bent, the cross beam pin can have a certain rotating space to absorb impact force.
Description
technical field [0001] The application relates to an assembled polymer material protective fence. Background technique [0002] Traditional guardrails generally include concrete guardrails, iron guardrails, corrugated steel guardrails, etc. However, there are fatal shortcomings in this type of guardrail, that is, the rigidity is too strong and the energy absorption capacity is poor. When the vehicle collides with it, most of the energy is absorbed by the vehicle, thereby causing major injuries to the vehicle and the occupants. In addition, there are problems such as heavy quality, difficult transportation, high cost and maintenance costs, and difficult molding. Contents of the invention [0003] In view of the above-mentioned technical problems existing in the prior art, the purpose of this application is to provide an assembled polymer material guardrail, which can be widely used in large-scale manufacturing factories, airports, parking lots, logistics companies, etc. S...
