Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an adjustable precast lintel mold. Background Technology

[0002] In building construction, lintels are crucial components used to support the load above door and window openings, ensuring their stability and safety. Existing precast concrete lintels often require laying plastic film on the construction site, using pre-cut plywood as templates, and securing them with mortar and nails. However, due to the wide variety of door and window specifications and lengths, while the precast lintel molds are fixed in size and cannot be adjusted, multiple precast lintel molds of different specifications need to be prepared in advance, increasing construction costs.

[0003] To address the aforementioned technical issues, CN117067365A discloses an adjustable precast concrete lintel mold and its usage method. This mold is formed by enclosing a base plate, a first sealing plate, a second sealing plate, and two side plates. The size of the casting area of ​​the mold can be adjusted by sliding a partition. This not only simplifies the manufacturing process and enables the construction of precast lintels, but also allows the same precast lintel mold to be used to cast lintels of different specifications, thus reducing costs.

[0004] However, the lintel mold provided by this technical solution still has certain defects: 1. The mold can only be adjusted in the length direction, but cannot be adjusted in the width direction, so its size applicability is limited; 2. The mold does not have the function of pre-reserving pipelines, which means that after the lintel is formed, chiseling operations are required at the location where pipelines need to be installed, increasing the workload of workers.
