As shown in fig. 1 to 2, a bridge deck safety protection guardrail vertical rod fixing device according to an embodiment of the present application includes a pillar 1, a bracket 2, and a hook member 8.

The support column 1 is vertically arranged; the bracket 2 is transversely arranged; the lower part of the strut 1 is connected with the middle part of the bracket 2; the hook member 8 has a rod portion 4 and a hook portion 3 connected to one end of the rod portion 4, and the other end of the rod portion 4 is adjustably lockingly connected to the bracket 2.

Specifically, bridge floor safety protection guardrail pole setting fixing device who this application embodiment mainly contained: a cross fork formed by welding reinforcing steel bars, two hooks with screw heads made of round steel and two nuts matched with the hooks.

Two steel bars with the diameter not smaller than C16 can be used and are horizontally aligned up and down, and the two ends of the two steel bars are welded together to form the whole bracket 2. The length of the reinforcing steel bars is determined according to the width of the guardrail embedded reinforcing steel bars 7 of the bridge floor. Then, a steel bar with the length of 45cm and the diameter not less than C32 is selected as the pillar 1 and welded at the middle position of the support 2, so that the pillar 1 and the support 2 form a cross, but the upper part of the pillar 1 is required to be ensured to exceed the support 2 by about 40cm. The upright stanchion of the guardrail to be installed is inserted into the upper part of the stanchion 1, thereby realizing the installation of the safety protection guardrail.

The crotch of taking the silk head chooses for use the round steel that the diameter is not less than A12, and one end is made into crotch portion 3, and one end is as pole portion 4 and car silk external screw thread 6, and car silk length is not less than 10cm, and length should be according to 7 intervals of guardrail embedded steel, and guarantee that crotch portion 3 can catch on guardrail embedded steel 7 can.

When the cross guardrail embedded steel bar fixing device is used, as shown in fig. 2, the short edge of the welded cross vertical steel bar is downwards kept horizontally placed with wall guardrail embedded steel bars, one side of the smooth round steel bar elbow is hooked on the wall guardrail embedded steel bars, the tail of the smooth round steel bar elbow penetrates through the gap of the left end of the cross transverse steel bar, and the cross transverse steel bar is fixed through the tightening nut. The right end also uses plain steel bar elbow to collude on wall formula guardrail embedded bar, and the afterbody passes the horizontal reinforcing bar right-hand member clearance of cross, and it is fixed to tighten nut. And finally, the common steel pipe is inserted on the upper edge of the cross-shaped steel bar, so that the installation time of the safety protective guard is greatly shortened, and the working efficiency is improved.

In some embodiments, the number of the hook members 8 is at least two, the more the hook members 8 are arranged, and the connection between the bridge deck safety protection guardrail upright rod fixing device and the guardrail embedded steel bars 7 is more stable in the embodiment of the application.

The hook members 8 may be disposed on two sides of the bracket 2 in a dispersed manner, or may be disposed on the same side of the bracket 2.

If the number of the hook elements 8 is even, the even number of the hook elements 8 are symmetrically arranged on two sides of the support 2 relative to the support 1 so as to balance stress and avoid deformation caused by uneven stress.

The support 2 can be composed of two reinforcing steel bars, a through groove for the rod part 4 of the hook part 8 to pass through is formed between the two reinforcing steel bars, so that the hook part 8 can be randomly adjusted to be connected with the support 2 according to actual conditions. The support 2 can also be made of a steel plate, and a plurality of through holes are formed in the steel plate for the rod part 4 of the hook part 8 to pass through, so that the same connecting function and position adjusting function can be realized.

The supporting column 1, the support 2 and the hook piece 8 can be made of steel plates, steel pipes and other metal materials except steel bars, and the selection is flexible and various.
