Description

Technical Field

[0001] This utility model relates to the field of box girder hole forming technology, specifically to a novel box girder ventilation hole forming device. Background Technology

[0002] In modern bridge construction, box girders are a common structural form widely used in various large bridges. The internal space of a box girder is relatively enclosed, and during concrete pouring and use, hydration heat is generated and harmful gases accumulate. Installing ventilation holes can effectively promote air circulation inside the box girder and reduce its internal temperature.

[0003] In the prior art, utility model patent CN217777282U discloses a precast box girder ventilation hole forming device, including a ventilation hole mold, a box girder template, a first fixing clamp, a second fixing clamp, and a fixing sleeve. Two box girder templates are provided, and a precast box girder component is formed by casting between them. Mold holes are aligned on the box girder templates, and the ventilation hole mold passes entirely through the mold holes, with the two molds being sized to fit each other. The first and second fixing clamps are respectively located on the outer sides of the two box girder templates. A limiting plate is provided at the end of the ventilation hole mold, and the limiting plate is interlocked with the first fixing clamp. The fixing sleeve is fitted over the ventilation hole mold and connected to the second fixing clamp. The forming device provided by this utility model patent can stably fix the ventilation hole mold on the outer side of the box girder template, thereby forming ventilation holes during the subsequent box girder casting process; it has a simple structure, reasonable design, and is easy to disassemble.

[0004] The aforementioned new type of box girder ventilation hole forming device will not deform, break, or shift position during use, thus fully ensuring the quality of hole forming. However, the device does not have a scale, and it is impossible to know whether it has a component to control the drilling depth. Therefore, it cannot ensure that the drilling depth meets the requirements, resulting in poor performance during use. Improvements are needed. Utility Model Content
