Fire-proof rolling shutter doors are widely used in commercial buildings, factories and underground garages. Details of measurement and design are as follows:
Step 1: General Classification of Curtain Installation
1. It can be divided into:
On the fixture, the guide rails on both sides of the curtain are installed inside the entrance of the building, that is, the effective net width of the entrance after installation is the width of the original entrance minus the width of the two guide rails (200*2). Generally, the installation between the two building pillars is seen.
Side installation, that is, the guide rail on both sides of the curtain door is installed in the outer hole of the building, that is, the effective net width of the installed door hole is the width of the original door hole, generally see the wall open door to install the curtain door.
邊緣媒介機構,即卷簾兩側導軌安裝在建築物內孔邊同時,安裝在樓洞外的另一邊,也就是說門孔安裝後是有效的淨寬度是原始門孔的寬度減去導軌(200 * 1),常見的看到不規則建築列或安裝孔之間。
Edge media mechanism, that is, the guide rail on both sides of the curtain is installed at the side of the inner hole of the building and at the same time on the other side of the outside hole of the building. That is to say, the effective net width of the door hole after installation is the width of the original door hole minus the guide rail (200 * 1). It is common to see the irregular building row or between the installation holes.
2. Arrange vertically or vertically:
Beam: That is, the door head behind the curtain door is suspended above the door of the original building, usually the height of the door head is 400 mm.
Under the beam: that is, the curtain door head is suspended at the bottom of the original building doorway. The height of the door head is generally 400 mm. The actual effective net height is the height of the original building entrance minus the height of the entrance (which should be paid special attention to).
Step 2: Check the scenario
1. To inspect the construction structure of the rolling curtain door installed on the spot, make the choice of the type of rolling curtain door according to the actual situation, and require the installation of solid two-end machine head plate and guide rail. For the installation of double-track and double-curtain, it is necessary to consider that the installation thickness of the guide rail at both ends must reach 400 mm, and the thickness of the main organ board should be 900 mm.
2. The wireframe of water, electricity and other pipeline bridges must pass through shutter holes. It can often be practiced to install wireframe doors with wide edges of pipeline bridges. The narrow gate holes in front of bricks and stones are used to measure one side of the pipeline bridges; or to install the roof of the pipeline bridges on the top of the door to reduce the installation position of the doors, reduce the effective height of the doors, and effectively prevent the spread of fires after sealing with fire-proof rolling curtain materials.
3. After determining the design and installation of the two ends of the head plate and the position of the guide rail, the tape measure of the door hole is started. Width = the distance between the back of both ends of the guide rail and height = the distance from the ground to the top of the nose plate. If the medium is installed, it needs to be installed and sealed. Width = shutter width, height = distance from building top to rail top + 50mm.
4. For the entrance of irregular buildings, the noseboard firmly installed at both ends should take full account of the installation position of guide rails (or double guideways), borrow materials such as bricks, angle steels, H steel reinforcement, or support width or height only to cut off narrow installation width or height to resort to block masonry or fireproof materials.
