Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, and more specifically to the technical field of a ventilation and rainproof exterior wall structure. Background Art

[0002] The petroleum and chemical industry is a key industrial sector, but its production process is often accompanied by high-risk safety issues. With the continuous updating of production equipment and the development of technology, solutions for the explosion venting, ventilation, rain protection and other needs of Class A factories are also constantly evolving. Currently, in actual production, a large number of designs use some exterior wall measures to meet these needs, but there are still some challenges and limitations. The common ventilation methods for calcium carbide explosion venting factories are mainly the following: 1. Installing openable windows or ventilation shutters on the outer wall; 2. Mechanical ventilation through the installation of roof ventilation skylights or fans; 3. Using a large air inlet exterior wall ventilation structure.

[0003] However, none of the above designs can simultaneously provide rain and snow protection and good natural ventilation. Rain and snow can drift into the factory, reacting with raw materials, resulting in waste and seriously affecting safe production. Therefore, effectively organizing natural ventilation and rain and snow protection in the building is crucial. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems by providing a ventilated and rainproof exterior wall structure. This not only solves the problem of insufficient ventilation in factory production workshops, thereby steadily increasing air flow and passively reducing building energy consumption, but also effectively prevents the infiltration of rain and snow, reduces the waste of raw materials, and mitigates safety risks.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

Preferably, the diagonal steel supports are 1200mm long, with the spacing between adjacent transverse steel supports being 900mm. Other lengths are acceptable to meet design requirements.

[0011] In one embodiment, the ventilation and rain / snow shielding unit includes an inclined corrugated steel plate, a lower purlin arranged below the lower portion of the corrugated steel plate, and an upper purlin arranged below the upper portion of the corrugated steel plate;

[0012] The lower purlins are connected to the transverse steel support and the oblique steel support by rivets respectively, and the upper purlins are connected to the oblique steel support by rivets.

[0013] In one embodiment, the corrugated steel sheet is connected to the lower purlin and the upper purlin by self-tapping screws, and the lower purlin and the upper purlin are both arranged in a tangential distribution with the corrugated steel sheet.

[0014] In one embodiment, a trim plate is provided at the bottom end of the ventilation rain and snow shield unit. The trim plate is a U-shaped plate with its opening facing the ventilation rain and snow shield unit. The lower side of the U-shaped plate is connected to the lower purlin by rivets; the upper side of the U-shaped plate is connected to the corrugated steel plate by rivets.

[0015] In one embodiment, the gap between the lower side of the U-shaped plate and the lower purlin is filled with sealant, and the gap between the upper side of the U-shaped plate and the corrugated steel plate is filled with sealant.

[0016] Specifically, a sealing structure is formed by using U-shaped plates and sealants to wrap the oblique steel supports and corrugated steel plates.

[0017] In one embodiment, the leakage prevention component includes a flashing plate arranged at the connection between the topmost ventilation and rain and snow protection unit and the upper outer wall. The flashing plate is a bent part, the upper side of the bent part is tightly attached to the outer side of the upper outer wall, and the lower side of the bent part is tightly attached to the outer side of the corrugated steel plate.
