Construction method of concrete arched door and window lintel

Abstract

The invention relates to a construction method of a concrete arched door and window lintel, and belongs to a civil engineering building construction method, which comprises the following construction steps of: production of templates: 1) production of a bottom template: the bottom template consists of a bottom board and a reinforcing rib board, the middle section of the bottom board is a semi-circular section, the left and right sections of the bottom board are symmetrically downward vertical sections, and the middle of the bottom surface of the bottom board is welded with the reinforcing rib board; and 2) production of side templates: the center of a long bottom side of a rectangular wood board is used as a center of a circle, and the radius of the middle section of the bottom template is used as a radius to be cut into a semi-circular opening; and installation of templates: 1) installation of the bottom template: the left and right vertical sections of the bottom board are correspondingly and fixedly arranged on the wall at the left and right ends of the concrete arched door and window lintel by expansion bolts in accordance with the alignment position, and then a reinforcement cage is placed; 2) installation of side templates: the two side templates and the front and back sides of the bottom template are correspondingly matched, long baseplates are arranged, and split bolts are used to fix the front and back side templates; and pouring of lintel. The lintel is simple and practical, and has an excellent sealing performance.

Description

technical field [0001] The invention belongs to a construction method for industrial and civil buildings, in particular to a construction method for concrete door and window lintels. Background technique [0002] In construction engineering, in order to pursue artistic effects, many buildings design door and window heads in the shape of round arches, with a smooth appearance and the aesthetic feeling of combining Chinese and Western styles. However, round arched door and window heads require concrete round arch lintels. This concrete round arch The construction of shaped lintels is difficult, and the upper part is not suitable for masonry. There are problems such as easy cracking, difficulty in making formwork, and difficulty in pouring and forming arched parts, which often cause quality problems in later construction. Contents of the invention [0003] The object of the present invention is to propose a construction method for concrete arched door and window lintels, whic...
