Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary ventilation device for building construction. Background Art

[0002] Ventilation is a technology that uses natural or mechanical methods to allow wind to pass through unhindered and reach a room or a sealed environment to create a hygienic, safe and suitable air environment. During the construction of a building, the indoor environment is relatively closed, the air circulation is poor, and the building materials have irritating odors. If the construction workers inhale them for a long time, it will cause physical discomfort. Therefore, during the indoor construction process, air circulation must be maintained at all times.

[0003] A Chinese patent with announcement number CN220303816U discloses a temporary ventilation device for building construction, which enables the ventilation component to move quickly to a specified position through a movable seat. Then, according to the needs of the building construction site, the positions of the first sliding frame and the second sliding frame are adjusted, and the first sliding frame and the second sliding frame are locked by a clamping member, thereby improving the convenience of the use process and facilitating storage and placement.

[0004] Although the device uses the first sliding frame and the second sliding frame to quickly move the ventilation assembly, the ventilation assembly pressurizes the surrounding air and blows it to the designated position when blowing air, and the indoor air does not circulate with the external air, which makes the indoor ventilation effect worse. To this end, we provide a temporary ventilation device for building construction to solve the above problems. Utility Model Content
