AI Technical Summary
In existing construction projects, the lintels around the openings of electrical boxes or fire extinguisher boxes easily clash with the masonry walls, resulting in poor appearance and molding quality of the masonry walls. It is also difficult to control the squareness of the rectangular openings, which increases the workload of installing the electrical boxes later.
A precast concrete frame mold is designed, including a rectangular outer mold and a rectangular inner mold. The casting area is formed by connecting plates and embedded parts. The mold can prefabricate an integrated concrete frame to replace the lintel of the electrical box or fire extinguisher box opening.

Description
Technical Field
[0001] The utility model belongs to the technical field of template construction, and in particular relates to a concrete frame prefabricated mold. Background Art
[0002] During the construction of infill wall masonry in building projects, it is generally necessary to reserve openings on the wall or holes for installing electrical boxes. According to the specifications, openings larger than 300mm generally need to be equipped with lintels, and the length of the lintel extending into the masonry wall must be no less than 250mm. Before the masonry construction, bricks need to be arranged in advance according to the module of bricks or blocks, and then the position of the opening must be reserved.
[0003] However, existing lintels often exist around the openings of electrical boxes or fire extinguisher boxes, which can easily clash with each other. Bricks often need to be cut around the openings, seriously affecting the appearance of the masonry wall and significantly impacting the quality of the wall. This approach also makes it difficult to maintain the squareness of the rectangular opening, resulting in a lot of labor required to close the opening after installing the electrical box, and the molding quality is poor. Therefore, a concrete frame can be used to replace the lintel. Therefore, a mold for prefabricating a concrete frame is needed. Utility Model Content
