Background
With the continuous development of the building industry, in order to facilitate construction, a mold for manufacturing a concrete precast block is developed rapidly in recent years, and the concrete precast block mold is mainly used for pouring and molding concrete. However, most of the molds are integrally formed and difficult to disassemble, and the formed blank is fluffy in texture and difficult to demold, so that the concrete precast block is easy to generate flaws, the blank is easy to fall off slag in transportation, and the like, and the concrete precast block is poor in quality and easy to have adverse effects on building load bearing and the like.
In building construction, doors and windows are indispensable members. When a door and window opening is formed in a wall body and the wall body opening is larger than 300mm, in order to support various loads transmitted by a masonry body on the upper portion of the opening and transmit the loads to walls on two sides of the opening, such as a door and a window, a cross beam is required to be arranged on the door and window opening and is called a lintel.
At present, two methods are adopted for pouring the lintel, wherein the first method is in-situ pouring, namely, after the steel bars are planted on the top surface of the opening, the template is processed and installed, and then concrete is poured; the method has the disadvantages that each lintel needs to be poured independently, relevant quality defects such as missing edges, corner falling and the like are easily caused after the form removal, and the lintel of the door and the window and the precast block have poor appearance. The door and window lintel differs with the specification of the prefabricated section, the turnover number of times of the wooden template is limited and the strength is poor, so that the precision of the prefabricated section is poor, the construction cost is high, and the working efficiency is low. The other method is to prefabricate the lintel, which meets the requirement of wall reform in the building industrialization development, but because the doors and windows have various specifications and different lengths and heights, workers are required to process a plurality of lintel templates with different specifications in advance before the lintel is prefabricated. Although the method ensures the size and the appearance and improves the construction efficiency, the templates of the lintel are mostly scattered templates, so that the templates of the prefabricated lintel can only be used once, the construction waste is excessive, the resource waste is caused, and the construction cost is increased.
