Description

Technical Field

[0001] This utility model relates to the technical field of bridge railings, and in particular to a bridge railing structure. Background Technology

[0002] Bridge railings are a common protective device found on both sides of bridges, consisting of multiple long, narrow railings and supporting columns, designed to prevent pedestrians and vehicles from accidentally falling off the bridge. During bridge construction, workers typically first drill holes in the supporting columns on the bridge structure to locate the installation positions. Then, bolts are used to fix the bridge railings to these holes. Finally, multiple railings are connected to complete the installation, thus preventing pedestrians and vehicles from accidentally falling off the bridge. Therefore, a suitable bridge railing structure is particularly needed.

[0003] However, in the existing bridge railing structure, most bridge railings have relatively long crossbeams. Long crossbeams are inconvenient to produce and transport, so they need to be cut and then installed directly on the construction site. This operation will affect the continuity of the crossbeams and the protective quality of the railing. Utility Model Content

Align the three sets of through holes 901 on one end of the crossbeam 6 with the positions of the two sets of crossbeams 6. Then, pass one end of the fixing bolt 904 through the flat washer 905 and then through the through hole 901. Then, thread it to the connecting block 902 through the threaded groove 903. Then, put one end of the other set of crossbeams 6 on the other end of the connecting block 902. At the same time, align the three sets of through holes 901 on one end of the crossbeam 6 with the three sets of threaded grooves 903 on the other end of the connecting block 902. Then, pass one end of the fixing bolt 904 through the flat washer 905 and the through hole 901 in sequence, and then thread it to the connecting block 902 through the threaded groove 903. At this time, the six sets of fixing bolts 904 fix the two sets of crossbeams 6 to the connecting block 902, thereby splicing and connecting the two sets of crossbeams 6.

Then, one end of the connecting bolt 803 is passed through the spring washer 804 and the limiting hole 801 in sequence. Then, the connecting bolt 803 is threadedly connected to the crossbeam 6 through the threaded hole 802. Tightening the connecting bolt 803 can fix the crossbeam 6 on the surface of the supporting angle steel 5.

[0027] Furthermore, the locating hole 801 and the threaded hole 802 are of the same size, and one end of the connecting bolt 803 passes through the supporting angle steel 5. With the setting of the locating hole 801, the locating hole 801 facilitates the connecting bolt 803 to pass through the surface of the supporting angle steel 5.

[0028] Furthermore, one end of the connecting bolt 803 is threaded to the crossbeam 6. The connecting bolt 803 is an M16 model. By setting the connecting bolt 803, when in use, one end of the connecting bolt 803 passes through the limiting hole 801 and is threaded to the crossbeam 6 through the threaded hole 802, which can fix the crossbeam 6 to the surface of the supporting angle steel 5.

Then, pass one end of the connecting bolt 803 through the spring washer 804 and the limiting hole 801. The connecting bolt 803 is then threaded to the crossbeam 6 through the threaded hole 802. Tighten the connecting bolt 803 to fix the crossbeam 6 to the surface of the supporting angle steel 5. Next, splice the crossbeam 6. At this point, one end of the connecting block 902 can be fitted inside one end of the crossbeam 6, while three of the holes on the surface of the connecting block 902 are aligned. The threaded groove 903 is aligned with the three sets of through holes 901 on one end of the crossbeam 6. Then, one end of the fixing bolt 904 passes through the flat washer 905 and then through the through hole 901. It is then threadedly connected to the connecting block 902 through the threaded groove 903. Then, one end of another crossbeam 6 is fitted onto the other end of the connecting block 902. At the same time, the three sets of through holes 901 on one end of this crossbeam 6 are aligned with the three sets of threaded grooves 903 on the other end of the connecting block 902.
