Henan fireproof rolling shutter door is developing rapidly. Henan fireproof rolling shutter door style and measurement design considerations. The fireproof rolling shutter door is widely used in commercial buildings, workshops and underground garages. The specific installation standards are as follows: measurement design: step one: general classification of roller shutter installation. Self inspection of fire shutter: manual operation mode: whether a circular iron chain set in the storage box at one side of the shutter can be found to operate the lowering and rolling. supply Fire door When the installation form is wall side installation: when there are embedded parts (steel plates) in the building, after cleaning the installation datum plane, check and verify whether the size and external position of the embedded parts are suitable for the installation drawing design. If the design requirements are appropriate, this is the datum plane for the installation of large and small supports. Fire door Manufacturer The facing bricks around the wall projections shall be cut and matched with the whole brick, and the edges shall be clean. (Check the date of delivery and the date of maintenance; carbon dioxide, dry powder and clean gas extinguishers are outdated if they have been delivered for 5 years or maintained for 2 years; foam extinguishers are outdated if they have been delivered for 3 years or maintained for 1 year, and they need to be sent to the fire extinguisher factory or professional maintenance unit for maintenance). Henan fireproof rolling shutter door After the Henan fireproof rolling shutter door is installed, the ceiling edge should be 50mm away from the curtain plate to avoid friction; c. The foundation dimensions of rolling shutter doors and parts shall be measured, which shall be consistent with the requirements of the design institute.

Henan fire door development prospects 1. The fire door industry is also an emerging industry, with huge market capacity and market potential. 2. Due to the high qualification threshold of fire doors, there are not many manufacturers that can really enter the fire door industry, but also Grade C fire doors Grade C fire doors Henan fire doors. According to incomplete statistics, there are more than 1000 fire door enterprises. supply Fire door This does not include those family workshop type processing units. The products produced by these processing units are of different grades, with prices ranging from hundreds to thousands of yuan. 3. The market pattern in the industry has not been formed yet. There are few large enterprises and brands, and there is no leading brand. The research, development and production of fire door products have played a positive role in ensuring the safety of people's lives and property. China's fire door market started late, but developed rapidly. In recent years, some European and American enterprises have actively participated in the competition in the Chinese fire door market, especially European enterprises, which are trying to make European fire doors occupy more of the Chinese market. Fire door Manufacturer In the face of competitors, we must face up to the current situation. On the one hand, we should learn from our competitors modestly, and on the other hand, we should strive to enhance our own strength. Fire door manufacturers in China are facing a huge challenge. Who can seize the opportunity in this challenge will become a winner in the market.

The introduction of Henan fire rolling shutter door is a kind of fire prevention and heat insulation facilities suitable for large openings of buildings. The product has played a certain role in the design and installation of technology. supply Fire door Fire resistant rolling shutter doors are widely used in the fire partition area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. Installation requirements and instructions for fire shutter door 1. The upper part of the opening where the shutter door is installed shall not be equipped with ventilation pipes, water pipes, etc; 2. After the roller shutter door is installed, install the suspended ceiling. The edge of the suspended ceiling should be 50mm away from the curtain plate to avoid friction; 3. During commissioning and use, it is strictly prohibited to stand at the bottom. Fire door Manufacturer Electrical facilities shall not be removed without authorization; 4. According to the fire management regulations, the chain lubricating oil of the starting motor must not be missed during the routine fire safety inspection every quarter, which is also an important part of the omission of many property management units or fire protection units during the inspection.

Henan fireproof door installation method The fireproof door is divided into steel fireproof door and wooden fireproof door according to the material. There are some differences in the installation method of the two fireproof doors. supply Fire door The fire rating is slightly different. You must pay attention to the details when installing. First of all, when installing the wooden fireproof door, the size of the door frame should be 20mm smaller than the opening, and the lower foot of the door frame should be buried 20mm below the ground. The door frame should be firmly fixed with the wall, and perpendicular to the corner. The vertical frame and bracing frame shall be straight and at the same angle to avoid planing and sawing. There shall be no less than 3 fixed points on both sides of the door frame, and the spacing shall not be greater than 800mm. Secondly, during the installation of the steel fire door, considering the bending deformation of the door frame, it is necessary to support the door frame with wooden braces in the width direction of the door frame. The lower foot of the door frame is buried 20 mm below the ground, and then the door frame is welded with the embedded parts on the wall. Then make a hole in the wall at the upper corner of the door frame, and pour concrete of cement, sand and expanded perlite (1:2:5), which can be used after the concrete has set. Fire door Manufacturer Requirements for airtightness of fire doors: there are clear requirements for the size of the gap at each overlap of fire doors: for steel fire doors, the overlap between the leaf and the door frame shall not be less than 10mm, and the gap between the leaf and the door frame on both sides shall not be more than 4mm. The gap after the installation of the fire door cannot be too large, otherwise the airtightness of the fire door is difficult to guarantee, and it is difficult to reflect its role in restraining fire and smoke spread under fire conditions.

A brief talk on the problems encountered in the fire acceptance of Henan fire rolling shutter door 1. The curtain plate coating falls off and rusts, and the curtain plate has obvious pressure pits, concave convex, and penetrating holes. supply Fire door The rolling shutter is a complete fire protection product. If the shutter has problems, it will directly affect the fire resistance limit index of the rolling shutter. 2. The guide rail is deformed and the curtain board is stuck or falls unevenly. The fireproof rolling shutter door generally moves along the guide rail. If the guide rail is twisted or broken, the rolling shutter door will not be able to move to the specified position, which will not achieve the effect of fire separation. 3. On the roller shutter, the lower limit fails or the limit line is wrongly connected. Fire door Manufacturer This often happens on the fire roller shutter of the atrium. Because the fire roller shutter of the atrium is sometimes installed outside the walkway of the upper floor, there is no floor under the roller shutter to close it, and a large gap is leaked, so the fire separation of the upper and lower floors cannot be reached.
