Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0019] see Figure 1 to Figure 4 As shown, this embodiment adopts the following technical solutions:

[0020] A construction method for concrete circular arched door and window lintels, the steps are:

[0021] 1. Make window molds for arched doors and windows 6: use steel bars of a certain diameter, cold bend them according to the arc of the arched doors and windows, and weld and reinforce the steel bars after setting out the arc. During the welding process, it is necessary to ensure the mold In addition to rigidity and stability, it is necessary to ensure the arch heigh...

Abstract

The invention discloses a construction method of concrete arch-shaped lintels of doors and windows. The construction method is characterized by comprising the following steps: (1) manufacturing a window hole die applied to arch-shaped doors and windows by cold bending steel bars with certain diameter according to radian of the arch-shaped doors and windows, completing pay-off radian of the steel bars and then welding and reinforcing the steel bars, wherein rigidity and stability of the die need to be ensured, and the size requirements such as arch height, chord length and radian of an arc and the like need to be ensured in the welding process; and (2) manufacturing a bottom template by determining the size of the bottom template according to the bottom size of the window hole die, wherein the bottom template adopts a rectangular wood board, and the length and the width are consistent with the bottom size of the window hole die. The construction method of the concrete arch-shaped lintels of doors and windows adopts an on-site model casting method; the method is simple and convenient to construct, easy to operate, low in manufacturing cost and excellent in construction effect; the arch parts can be conveniently cast and are solid and firm.

Description

technical field [0001] The invention relates to the technical field of building construction methods, in particular to a construction method for concrete arched 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 aim at the defects and deficiencies of the prior art, and provide a construc...
