[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.

[0026] Refer to Figure 1The present application relates to a guardrail frame for tying anti-collision guardrail steel bars, the guardrail frame comprising: a support frame 1 and a control frame 2, wherein the outer end of the support frame 1 is connected to the bottom end of the control frame 2, the control frame 2 is inclined toward its outer side at the same angle as the embedded steel bars of the anti-collision guardrail are inclined toward its inner side, and its outer side surface can be used to fit with the outer side surface of the embedded steel bars of the anti-collision guardrail.

[0027] Specifically, the support frame 1 plays the role of supporting and maintaining the stability of the guardrail frame; the control frame 2 plays the role of positioning and controlling the embedded steel bars of the anti-collision guardrail at a certain angle; it should be understood that the outer end and outer side of the support frame 1 refer to the side opposite to the support frame 1 when the support frame 1 is connected to the control frame 2; its inner end and inner side are the same side as the support frame 1 when the support frame 1 is connected to the control frame 2. It is also necessary to understand that the inner side of the embedded steel bars of the anti-collision guardrail refers to the side where the bottom of the embedded steel bars of the anti-collision guardrail is located, and the outer side is the side away from the bottom of the embedded steel bars of the anti-collision guardrail; in this way, by designing the outward inclination angle of the control frame 2 and the inward inclination angle of the embedded steel bars of the anti-collision guardrail to be the same, it can be ensured that when the embedded steel bars of the anti-collision guardrail and the guardrail frame are placed on the ground, the two can fit together, so that the outer side of the control frame 2 can be used as a reference for the binding of the steel bars of the anti-collision guardrail to improve the positioning effect, thereby avoiding the occurrence of uneven linear shapes of embedded steel bars, uneven heights, insufficient control of steel bar spacing, and misalignment of the guardrail after concrete pouring. When in use, place the guardrail frame on the ground near the embedded steel bars of the anti-collision guardrail, and then translate it in the direction close to the embedded steel bars of the anti-collision guardrail until the two fit together, and then move it in the opposite direction for 4.5cm to ensure that the thickness of the protective layer is qualified; finally, the anti-collision guardrail steel bars and protective layer pads can be positioned and bound based on the guardrail frame. Exemplarily, the inclination angle of the control frame 2 toward the outside and the inclination angle of the embedded steel bars of the anti-collision guardrail toward the inside can be 84 degrees.

[0028] From the above description, it can be seen that the present application achieves the following technical effects:

[0029] In the embodiment of the present application, a guardrail frame positioning method for binding anti-collision guardrail steel bars is adopted instead of the wire positioning method, through a support frame 1 and a control frame 2, wherein the outer end of the support frame 1 is connected to the bottom end of the control frame 2, and the control frame 2 is inclined toward its outer side at the same angle as the embedded steel bars of the anti-collision guardrail, and its outer side surface can be used to fit with the outer side surface of the embedded steel bars of the anti-collision guardrail; the purpose of effectively improving the positioning effect is achieved, thereby achieving the technical effect of avoiding the uneven linear shape of the embedded steel bars, the misalignment of the guardrail after concrete pouring, and the like, thereby solving the technical problems of the uneven linear shape of the embedded steel bars, the misalignment of the guardrail after concrete pouring, and the like caused by poor positioning effect.

[0030] Preferably, the control frame 2 includes: a pair of angle steels 3 and a first channel steel 4. Wherein, both ends of the first channel steel 4 are respectively welded to positions near the top ends of the pair of angle steels 3, and its notch faces inwards; the pair of angle steels 3 are connected into a whole through the first channel steel 4 to form the control frame 2. The outer side surface of the control frame 2 can be used as a reference for binding the anti-collision guardrail steel bars, so that the positioning effect can be improved. Further, the center point spacing of the pair of angle steels 3 is 150 + 15N cm, where N is an integer; this can ensure a steel bar spacing of 15 cm. Furthermore, the length of the angle steel 3 is 120 cm.

[0031] Preferably, the support frame 1 includes: a pair of second channel steels 5. The outer ends of the pair of second channel steels 5 are respectively welded to the bottom ends of the pair of angle steels 3, and their notches face upwards; the bottom of the control frame 2 is supported by the pair of second channel steels 5, and the pair of second channel steels 5 are laid flat on the ground, which can effectively improve the stability of the guardrail tire rack.

[0032] Preferably, the support frame 1 further includes: a pair of third channel steels 6. One end of the pair of second channel steels 5 is respectively welded to the middle positions of the pair of angle steels 3, and the other ends are respectively welded to the inner ends of the pair of second channel steels 5, and their notches face upwards; the pair of third channel steels 6 support between the second channel steel 5 and the angle steel 3, which can improve the structural stability and effectively prevent the control frame 2 from tilting to an inclination angle different from that of the anti-collision guardrail embedded steel bars due to bending.

[0033] Preferably, a threaded hole 7 is provided on the low side wall of the notch of the second channel steel 5, and an adjusting bolt 8 is connected in the threaded hole 7; by rotating the adjusting bolt 8, the height of the support frame 1 can be slightly reduced or increased, so as to ensure that the control frame 2 can better fit the anti-collision guardrail embedded steel bars, thereby realizing the leveling function. Further, there are two threaded holes 7, and one adjusting bolt 8 is respectively connected in the two threaded holes 7; leveling is achieved by respectively adjusting the two adjusting bolts 8; the leveling efficiency can be improved.
