Other load limit signs or width limit signs are also installed. However, the signs are usually fixed to the height limit beams with bolts. When the signs are exposed to the external environment for a long time, the words on the surface of the signs are easy to fade or even invisible. The sizes and types of signs on the market are diverse, and there are deviations in the positions of the threaded holes for bolt connection on the signs. Therefore, it is difficult for height limit beams to adapt to signs of different sizes for installation. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, a height limiting device for highway engineering comprises two columns 1, a beam body erected on the upper ends of the two columns 1 and signboards 5 respectively arranged on the surface of the beam body, the beam body comprises two connecting columns 2 and two height limiting beams 3, the two ends of the two height limiting beams 3 are respectively fixedly connected to the two connecting columns 2, the two connecting columns 2 are respectively fixedly connected to the upper ends of the two columns 1, a supporting assembly is arranged at the lower ends of the two columns 1, and a plurality of connecting assemblies for installing the signboards 5 are arranged between the two height limiting beams 3;

[0024] The connecting assembly includes a cross rod 4, a mounting bolt 10 and a nut 12 threadedly connected to the mounting bolt 10. The ends of the cross rod 4 are fixedly connected to the surfaces of the two height limiting beams 3 respectively. Two rails 9 for sliding installation of the mounting bolts 10 are provided on the back of the sign 5. The surface of the cross rod 4 is provided with a travel groove 11 for the mounting bolt 10 to penetrate and install. When in use, the staff slides the mounting bolt 10 on the rail 9, and then after one end of the mounting bolt 10 passes through the travel groove 11 respectively, the nut 12 is put on the mounting bolt 10 and tightened to achieve the effect of fixing the sign 5.
