Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the air blowing and water spraying components used to measure airtightness and watertightness in the prior art have a single orientation and cannot be simulated during actual use. In the multi-angle wind and water conditions in the natural environment, the detected performance of doors and windows is different from the actual use, and a method and device for detecting the safety performance of doors and windows in construction projects are proposed.

Abstract

The invention discloses a door and window safety performance detection method and device for constructional engineering, and belongs to the field of door and window safety performance detection. The device comprises a platen and further comprises: a distance adjusting unit installed on one side of the surface of the platen, wherein an orientation changing unit is installed on the distance adjusting unit; a door and window fixing unit which is installed on the other side of the surface of the platen, wherein a partition unit is installed on the side, away from the distance adjusting unit, of the door and window fixing unit, and a paper strip fixing unit is installed on the inner side of the partition unit; and a detection unit which comprises fans, a fixed cylinder and a water spray head, at least three fans are mounted on the inner side of the mounting ring of the orientation changing unit in an annular array manner, the fixed cylinder is arranged in the center of the mounting ring of the orientation changing unit and fixed to the side faces of the fans, and the water spray head facing the door and window fixing unit is mounted on the fixed cylinder. The simulation condition is closer to reality, the strength of simulated wind and rain can be adjusted, the detection condition is closer to reality, and the detection effect is good.

Description

technical field [0001] The invention relates to the technical field of door and window safety performance detection, in particular to a method and device for door and window safety performance detection of construction engineering. Background technique [0002] The sealing performance of building envelope structures such as doors, windows and curtain walls directly affects the energy-saving performance of buildings and the comfort of indoor living. With the increase of the service life of the building, the sealing performance of the doors, windows and curtain walls in service will deteriorate due to the aging and failure of the sealing material and the deformation of the hardware, which will lead to the increase of indoor and outdoor heat convection, increase the energy consumption level of the building operation, and affect the indoor thermal environment. And air quality, serious problems such as water leakage will occur. Therefore, it is of great significance to study, de...
