An adjustable formwork and construction method for post-cast door openings

Abstract

The invention discloses an adjustable formwork for post-poured door openings and a construction method. By adoption of the adjustable formwork for the post-poured door openings and the construction method, the defects that construction of a door opening base layer is inconvenient, the consistency of results completed by different constructors is poor, construction cost is high, accuracy and firmness of the door opening base layer are low, and mounting of a door pocket can be hampered are overcome. The adjustable formwork comprises a top formwork body and two side formwork bodies, the two side formwork bodies are connected with the two ends of the top formwork body correspondingly, and the front edges and the rear edges of the top formwork body and the side formwork bodies are all provided with connecting flangings which are turned outwards. Extension portions are arranged on the upper ends of the connecting flanging of the side formwork bodies and extend out of the upper end of the top formwork body, a plurality of fixing holes are formed in the upper ends and the lower ends of the side formwork bodies as well as the right end and the left end of the top formwork body, and the front edge of the top formwork body extends out of the front edges of the side formwork bodies. A plurality of wedge pillow inserting holes are formed in the positions, close to the front edge and the rear edge of the top formwork body, of the top formwork body as well as the positions, close to the front edges and the rear edges of the side formwork bodies, of the side formwork bodies. The top formwork body comprises a left formwork body part and a right formwork body part, and the left formwork body part and the right formwork body part can be adjusted leftwards and rightwards to be connected together. Each side formwork body comprises a front formwork body part and a rear formwork body part, and each front formwork body part and the corresponding rear formwork body part can be adjusted front and back to be connected together.

Description

technical field [0001] The invention relates to a construction of a post-cast door opening, more specifically, it relates to an adjustable formwork and a construction method for a post-cast door opening. Background technique [0002] Buildings are inseparable from doors and door casings, especially in hotels, office buildings, residential buildings and other projects.
