[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1
[0023] See Figure 1-Figure 3 This embodiment provides a structure of a window-free natural ventilation exterior wall for a steel structure factory building, including an indoor side wall 2 and an outdoor side wall 4. A vertical air duct 5 is formed between the indoor side wall 2 and the outdoor side wall 4, and the vertical air duct 5 is located at the opening on the indoor side and an aluminum alloy louver opening window 1 is installed; the vertical air duct 5 is located at the opening on the outdoor side and an aluminum alloy louver 6 is installed. An electric rotary air fan 3 is installed in the vertical air duct 5 located directly below the aluminum alloy louver opening window 1; the vertical air duct 5 is bent, and the vertical air duct 5 is located below the aluminum alloy louver opening window 1. The wall surface near the indoor side and the vertical direction form an angle of 23, and the angle of the angle 23 is 66°. The wall surface near the outdoor side and the vertical direction form an angle of 42, and the angle of the angle 42 is 95°.
[0024] The indoor side wall 2 and the outdoor side wall 4 are arranged in parallel and welded together by hot-dip galvanized steel square tubes to form a wall surface; the specifications of the hot-dip galvanized steel square tubes are 120 / 80 / 60mm long*60mm wide*5mm thick.
[0025] The outer surface of the indoor wall 2 is covered with a single-layer aluminum plate 21, and the outer surface of the outdoor wall 4 is covered with a honeycomb aluminum plate 41; the inner surfaces of the indoor wall 2 and the outdoor wall 4 are both covered with fireproof steel plates 7; and Class A fireproof rock wool 22 is filled between the fireproof steel plates 7 and the single-layer aluminum plate 21.
[0026] Specifically, the thickness of the honeycomb aluminum plate 41 is 25 mm, the specification of the fireproof steel plate 7 is a 1.5 mm thick hot-dip galvanized fireproof steel plate, and the ventilation rate of the aluminum alloy louver 6 is 50%.
[0027] The width ratio of the indoor aluminum alloy louver opening window 1 to the outdoor aluminum alloy louver 6 is 1:1.5. Specifically, in this embodiment, the widths of the outdoor aluminum alloy louver 6 and the aluminum alloy louver opening window 1 are 340 mm and 220 mm respectively.
[0028] The aluminum alloy louver 6 and the outdoor side wall 4 are fixed by a drip line 61 , and a seal 62 is installed between the aluminum alloy louver 6 and the indoor side wall 2 .
[0029] Specific working principle: The ventilated exterior wall forms a vertical air duct 5 between the indoor side wall 2 and the outdoor side wall 4. An electric rotary fan 3 is installed on one side of the indoor aluminum alloy louver opening window 1 of the air duct. When the lower angle formed by the fireproof steel plate 7 on the inner surface of the vertical air duct 5 is 114 degrees and the upper angle is 95 degrees, the instantaneous ventilation wind speed can reach up to 0.2M / S according to the environment. When ventilation is needed, turn on the electric rotary fan 3. This part is narrower than the inner side, forming a negative pressure space; at the same time, one side of the outdoor aluminum alloy louver 6 of the air duct is wider, forming a positive pressure on the indoor side, so that fresh air from the outdoor is sent into the room through the vertical air duct. When ventilation needs to be stopped, turn off the electric ventilation fan and adjust the indoor louvers to the closed state.
[0030] The above construction method can realize natural ventilation of the exterior wall of the steel structure factory, and the efficiency of indoor and outdoor air exchange is significantly improved compared with the traditional exterior wall. In the case of some special production processes that do not require the opening of the glass exterior windows, the use of electrically controlled rotary fans and indoor openable shutters can be used to utilize the indoor and outdoor air pressure difference to achieve indoor and outdoor air exchange and improve the indoor use environment. The exterior wall structure is simple to construct, and the component operation failure rate is extremely low, which meets the requirements of natural ventilation and effectively solves the problems of high energy consumption of mechanical ventilation without opening windows and easy failure of ventilation equipment after long-term use.
[0031] The above contents are merely examples of the structure of the present utility model. The technical personnel in the relevant technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the present utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
