Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a crash barrier assembly mold. Background Technology

[0002] Crash barriers are road safety facilities that achieve rigid impact protection through reinforced concrete structures. They are mainly used in the protective areas on both sides of urban bridges or in the median strips of highways. Crash barrier fabrication typically employs two methods: on-site formwork casting or prefabrication assembly. On-site casting requires installing formwork, tying reinforcing bars, and then pouring concrete, demanding high levels of worker skill and taking up a long construction period, resulting in low efficiency. Prefabricated crash barriers rely on high-precision steel molds combined with automated production lines to achieve rapid manufacturing and installation, leading to high construction efficiency.

[0003] Currently, precast reinforced concrete crash barrier molds suffer from problems such as complex installation processes and easy mold displacement upon flipping. Therefore, it is necessary to propose a crash barrier assembly mold to solve the above problems. Utility Model Content

The mold has a reasonable structural design and is easy to operate. By setting a first end mold, a second end mold, and two side molds around the bottom mold, a main body mold with an open top is formed. When forming the crash barrier, it can be quickly assembled and manufactured without the need for a mold table and without site restrictions. At the same time, by setting an arc-shaped groove on the bottom mold panel, the main body of the crash barrier can be cast in one go without secondary repairs and adjustments, so that its surface can reach a clear water finish and achieve good results.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a crash barrier assembly mold, including a bottom mold, a first end mold and a second end mold respectively surrounding both ends of the bottom mold, and two side molds respectively surrounding both sides of the bottom mold. The bottom mold, the first end mold, the second end mold and the two side molds are arranged together to form a guardrail main body mold with a guardrail main body forming cavity. Multiple tie rods are connected between the top of the first end mold and the second end mold. The bottom mold includes a bottom mold panel and a bottom mold support rib group fixed to the back of the bottom mold panel. The bottom mold panel is inclined downward from the end closer to the first end mold to the end farther away from the first end mold. The bottom mold panel has an arc-shaped groove at the end closer to the first end mold. The bottom mold panel has a multi-segment downward inclined surface from the arc-shaped groove to the end of the second end mold. The bottom end face of the bottom mold support rib group is parallel to the top surface of the guardrail main mold. Multiple reserved steel bar positioning holes are provided on the second end mold.

[0006] The aforementioned anti-collision guardrail assembly mold further includes a base mold disposed on the upper part of the guardrail main body mold. The number of base molds is two, and the two base molds are respectively disposed on both sides of the top of the guardrail main body mold near the first end mold.
