Problems solved by technology

Since the wooden formwork is connected by iron nails, most of the iron nails are deformed during the disassembly process, and the iron nails with severe deformation cannot be used again.

Abstract

The invention is a plastic template able to be used to cast the prefabricated frames of doors and windows in constructional engineering, connected of right-angle blocks, and regulating blocks in order, using horizontal and vertical support rods and regulating rods to support and fasten the regulating blocks in the inner frame of the plastic template, thus keeping angles, horizontality and verticality of the frame invariable all the time. After loosening the support rods and regulating rods and taking down them, the modules can be removed by striking the striking points on the regulating blocks and the right-angle blocks.

Description

Technical field [0001] The invention relates to a door and window frame formwork device for building engineering construction. Background technique [0002] At present, in construction projects, the frame of pouring doors and windows adopts a wooden formwork structure. It is made of square wood and planks that are processed to length and connected with iron nails. Before the wall is poured, the wooden formwork is fixed at the reserved door and window position of the wall, and the wooden formwork is removed after the concrete pouring is completed and the specified curing time is over. [0003] As we all know, in the process of making wooden formwork, square wood and boards are processed to length, and some of the remaining wood cannot be reused, which causes a part of wood to become waste. In addition, iron nails must be used to nail the cut-to-length wood, and the nailed wooden formwork must be corrected to ensure that the corners of the wooden formwork are at right angles...
