Description

Technical Field

[0001] This utility model belongs to the field of concrete mold technology, specifically relating to a precast composite beam mold. Background Technology

[0002] Precast concrete beams are concrete beam components that are prefabricated in a factory and then transported to the construction site for installation. They are one of the important precast components in modern construction engineering. Precast beams are a core component of prefabricated buildings, and their production process encompasses standardized procedures such as formwork assembly, rebar tying, and concrete pouring and curing.

[0003] Based on actual needs, the inventor developed a composite beam consisting of two horizontal beams and several longitudinal beams set between the two horizontal beams. Several cantilever beams, also known as beam ends, are provided on the outer surface of the horizontal beams.

[0004] However, in actual transportation, the ends of the beams are prone to exceeding the transportation width limit.

[0005] To address the aforementioned issues, the inventors implemented a modular design for the composite beam, dividing it into a main beam body and several beam ends. Several first connecting components are pre-embedded on the sides of the main beam body. Each beam end corresponds to one of these first connecting components, and a second connecting component is pre-embedded at one end of each beam end. These second connecting components are detachably connected to the first connecting components on the main beam body. Therefore, the two ends can be disassembled during transportation and reassembled at the construction site, effectively preventing the problem of excessive width.

[0006] Currently, there are no molds available on the market for producing the aforementioned composite beams. Utility Model Content
