Description

Technical Field

[0001] The present application relates to the technical field of wall-mounted ventilation shaft construction, and in particular to a rainproof ventilation device for flat vents in buildings. Background Art

[0002] General ventilation louvers are installed on the facade of buildings or structures, with the blades installed in the facade leaf frames. If the blades slope outward, rainwater will be smoothly guided to the outer edge of the blades and discharged to the outside. However, if the louvers are flat-mounted (of course, they are rarely used in general, but there are designs for them), no matter what angle the louver blades are, rainwater will inevitably fall into the building.

[0003] The existing ground ventilation shaft is a wall-attached ventilation shaft with a height of less than 200 meters above the ground, making it impossible to install blinds on the facade. The traditional design is to install blinds on the top surface, but the leakage problem of the blinds is ignored. When it rains, rainwater falls on the blinds or on the wall to which the blinds are attached, and will fall into the shaft. Utility Model Content

The upper blade 11 is a folding plate structure which is convex at the top and concave at the bottom. In a possible implementation, the upper blade is a 90-degree folding plate structure, and the specific implementation includes but is not limited to the use of angle steel; when using the angle steel, the angle steel is buckled inverted with the notch of the angle steel facing downward, and is used as an upper blade.

[0040] The lower louver 2 includes a plurality of lower blades 21 arranged side by side, and the lower blades 21 are folded plates with a convex bottom and a concave top. In a possible implementation, the lower blades 2 are folded plates with a 90-degree angle, and the specific implementation includes but is not limited to using angle steel with the notch facing upwards as the lower blades.

[0041] Each upper blade 1 is provided with a head plate 3 at both ends and at the bottom, and the top of the head plate 3 is connected to the bottom of the upper blade 1. A lower blade 2 is provided between two adjacent head plates 3, and one side of the lower blade 2 is connected to one side of the bottom of the head plate 3. In a possible implementation, the head plate 3 includes an upper section 31, a middle section 32 and a lower section 33. Among them, the upper section 31 is a triangular structure, and the top is connected to the bottom of the upper blade 1; the middle section 32 is a rectangular structure, and the top is connected to the bottom of the upper section; the lower section 33 is a trapezoidal structure that is narrow at the top and wide at the bottom, and the top is connected to the bottom of the middle section, and the side is connected to the side of the lower blade.

[0042] It should be noted that the first ventilation gap 12 is located above the opening of the lower blade plate 21 and within the opening range of the lower blade plate 2, and a second ventilation gap 4 is provided between the upper louver and the lower louver.

[0043] In this embodiment, the upper louvers are turned upside down to shed water, and the lower louvers receive water and drain water. The gaps between the upper and lower louvers serve as ventilation channels, thereby achieving the purpose of both ventilation and rain protection.

[0048] Example 2

[0049] Embodiment 2 of this specification provides a method for using a rainproof ventilation device for a building plane vent, comprising the following steps:

[0050] According to the ventilation demand, the size of the second gap between the upper louver and the lower louver is determined. The larger the gap, the greater the ventilation, and the smaller the gap, the smaller the ventilation;

[0051] The overlap angle between the upper and lower louvers is 45° to prevent rainwater from falling directly diagonally;

[0052] The head plate not only prevents rainwater from outside from entering the underground space, but also serves as a support for the upper blade plate;

[0053] Weld the installation base to the top of the wind shaft wall, and fix it to the top of the wind shaft wall with expansion bolts, ensuring a slope of 1.5% to 2% from inside to outside, so that rainwater can be discharged quickly;

[0054] Assemble, install the head plate on the base, install the upper louver on the top of the head plate, and install the lower louver on the side of the head plate;

[0055] After installation, apply waterproof and weather-resistant glue to the gaps on the outer circle of the base.

[0056] In the specific implementation: on-site measurement of the length and width of the air shaft; width, depth and wall thickness of the air shaft;

[0057] The size of the angle steel should be selected according to the size of the ventilation shaft and the maximum historical rainfall in the local area. The greater the depth of the ventilation shaft, the larger the angle steel should be selected. The greater the maximum historical rainfall in the local area, the larger the angle steel should be selected.

[0058] Determine the height of the upper and lower angle steels and the overlap size of the upper and lower angle steels. Generally, the greater the ventilation volume, the greater the distance between the upper and lower angle steels. The upper and lower angle steels are overlapped to ensure the overlap length. The overlap angle A is 45° (such as Figure 4 As shown in the figure, the rain is usually placed at an angle of 45° to the ground to prevent it from falling directly obliquely.

[0059] Calculate the cutting length of the angle steel according to the depth of the wind shaft, and calculate the number of upper and lower angle steels according to the lap width of the upper and lower layers of angle steel.

[0060] The head plate not only prevents rainwater from outside from entering the underground space, but also serves as a support for the upper angle steel.

[0061] The base is made of 10mm flat steel plate cut into steel strips matching the width of the wellhead, and then welded by groove welding. The welded base against the wall can be fixed to the top of the wind shaft wall with expansion bolts to ensure a slope of 1.5% to 2% from the inside to the outside, preferably 2%, so that rainwater can be discharged quickly.

[0062] Welding assembly.

[0063] After assembly, all exposed surfaces are painted with two coats of red lead anti-rust paint and then two coats of topcoat.

[0064] Use cement mortar to level the top of the air shaft wall before installation.

[0065] Waterproof treatment: Apply waterproof and weather-resistant glue to the gaps on the outside, sides and top sides of the base plate.

[0066] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0067] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
