Splicing type formwork for building construction

The utility model relates to the technical field of construction formworks, and discloses a splicing type formwork for building construction, which comprises a main formwork, two clamping blocks are fixedly arranged on one side wall of the main formwork, two first threaded through holes are fixedly formed in the tops of the two clamping blocks respectively, and two second threaded through holes are fixedly formed in one side wall of the main formwork. Clamping grooves are fixedly formed in the positions, corresponding to the clamping blocks, of the side wall, away from the two clamping blocks, of the main formwork, two second threaded through holes are fixedly formed in the top of each clamping groove, and a fixing groove is fixedly formed in each of the four corners of the side wall of the main formwork. Compared with a traditional building construction formwork, the building construction formwork has the advantages that two formworks can be quickly spliced by arranging the clamping blocks and the clamping g
