Description

Technical Field

[0001] The utility model relates to a tie-rod-free stainless steel mirror template, belonging to the field of road and bridge construction. Background Art

[0002] Anti-collision guardrails are important safety protection facilities in the field of highway engineering. They absorb collision energy by causing the vehicle to climb higher or deform its structure, thereby controlling the direction of the vehicle and avoiding abnormal vehicle direction, such as preventing the vehicle from driving into the opposite lane or outside the road.

[0003] Traditional cast-in-place guardrails mostly use tie-rod formwork for casting, which is not only prone to leakage at the tie-rod position, but also causes deformation due to insufficient formwork strength. After the concrete is poured, many tie-rod holes will be left on the surface, making the concrete surface unsightly. When the tie-rods rust, corrosion channels will be formed for the steel bars in the concrete structure. Utility Model Content

[0028] The inner mold 2 is installed on the inner side of the guardrail steel bar (not shown), and the inner mold 2 includes an inner mold mirror panel 21 and an inner mold connector provided on the inner mold mirror panel 21. The outer mold 3 is installed on the outer side of the guardrail steel bar, and the bottom of the outer mold 3 is connected to the bottom of the bridge deck 1. The outer mold 3 includes an outer mold mirror panel 31 and an outer mold connector provided on the outer mold mirror panel 31.

[0029] In one embodiment, the inner mold mirror panel 21 and the outer mold mirror panel 31 are both composed of 5mm carbon steel plate and 1mm stainless steel mirror panel. The stainless steel mirror panel is located close to the guardrail steel bar side. It has the characteristics of not easy to rust, easy to clean, and good demolding effect, which can effectively improve the appearance quality of the anti-collision guardrail.

[0030] Before installing the inner mold 2 and the outer mold 3, use a scraper or a hand grinder to grind the inner mold mirror panel 21 and the outer mold mirror panel 31 until the template is smooth and bright, and use an industrial hair dryer to blow away the debris and dust on the polished surface, and finally wipe it with a clean cotton cloth until there is basically no rust and dirt on the cotton cloth. Finally, use a sprayer to evenly spray the release agent on the surface of the mirror template, and wipe it gently with a rag after spraying to avoid excessive application of the release agent and oil on the template surface after the template is erected.

[0031] The adjustment structure 4 is connected between the outer wall of the inner mold 2 and the bridge deck 1 to adjust the installation angle of the inner mold 2. Specifically, the adjustment structure 4 is mainly used to adjust and control the verticality and linear control of the inner mold 2 and the outer mold 3 to ensure the construction quality of the anti-collision guardrail.

[0032] In this embodiment, the adjustment structure 4 includes a fixing member 41 embedded in the bridge deck 1 and at least two tension rods hinged on the fixing member 41, and the other ends of the at least two tension rods are respectively connected to the inner mold 2. The tension rod is a telescopic rod, and the telescopic rod includes two screw rods 42 respectively hinged on the fixing member 41 and the inner mold 2 and a steel pipe 43 threadedly connected to the two screw rods 42. There are two telescopic rods, one is horizontally connected to the bottom of the inner mold 2 and is arranged horizontally, and the other is connected to the middle of the inner mold 2. Of course, in other embodiments, multiple groups of telescopic rods can also be provided, which is not specifically limited here.

[0033] Among them, the inner mold connecting part includes an inner mold fixing part 23 arranged above the top of the inner mold mirror panel 21, and the outer mold connecting part includes an inner mold fixing part 33 arranged above the top of the outer mold mirror panel 31. The inner mold fixing part 23 and the inner mold fixing part 33 are partially staggered and overlapped in the width direction of the guardrail steel bars, and the staggered and overlapping parts are fixedly connected by at least two fixing structures arranged at intervals in the width direction of the guardrail steel bars.

[0034] The fixing structure includes fixing holes 331, 231 provided on the inner mold fixing part 23 and the inner mold fixing part 33 and fixing pins inserted into the fixing holes 331, 231. In the present embodiment, three groups of fixing holes 331, 231 are provided, and the fixing pins are inserted into the fixing holes 331, 231 on the inner mold fixing part 23 and the inner mold fixing part 33, thereby fixing the inner mold fixing part 23 and the inner mold fixing part 33, and then fixing the inner mold mirror panel 21 and the outer mold mirror panel 31. Since the inner mold fixing part 23 and the inner mold fixing part 33 are both provided above the inner mold mirror panel 21 and the outer mold mirror panel 31, the pouring and molding of the concrete will not be affected, and the construction quality and aesthetic appearance of the anti-collision guardrail can be effectively improved.
