In recent years, the quality of the rolling shutter door in Jinan has shrunk, and the design and composition materials of the rolling shutter door are all unqualified. In this regard, according to the current situation, we will briefly introduce the matters needing attention in the process of design, installation and use

一、設計合理，選型得當：維修設計人員應從不同建筑的性質、類型上設計有針對性的卷簾門，在設要嚴格按照消防技術規范要求，合理設置卷簾門，不得隨意降低卷簾門的等級。

1、 Reasonable design and proper selection: maintenance designers should design targeted rolling shutter doors according to the nature and type of different buildings. In the design, the rolling shutter doors should be set reasonably in strict accordance with the requirements of fire protection technical specifications, and the grade of rolling shutter doors should not be lowered at will.

1、在設計封閉樓梯間和未采用正壓送風系統防煙樓梯間前室的卷簾門時，應考慮卷簾門距頂棚的距離盡量不小于500mm，這樣一旦發生火災事故，可以有效防止人員疏散時煙氣進入樓梯間內，可保證樓梯間的防煙效果。

1. When designing the rolling shutter doors in the front room of enclosed staircases and those without positive pressure air supply system, the distance between the rolling shutter door and the ceiling should not be less than 500mm as far as possible. In this way, once a fire accident occurs, smoke can be effectively prevented from entering the stairwell during evacuation and the smoke prevention effect of the staircase can be ensured.

2、在設計有正壓送風系統樓梯間及其前室的卷簾門時，應考慮到單扇開啟面積與正壓送風量相匹配。如果開啟面積過大，在火災發生時，樓梯間內正壓送風系統運行的情況下由于風壓的作用，可能會造成開啟不夠順暢，不利于人員迅速疏散。

2. When designing the rolling shutter doors of staircases with positive pressure air supply system and its front room, the matching of single leaf opening area and positive pressure air supply volume should be considered. If the opening area is too large, in case of fire and the positive pressure air supply system in the staircase is running, due to the effect of wind pressure, the opening may not be smooth enough, which is not conducive to the rapid evacuation of personnel.

3、在建筑內日常人流量較多、使用頻率較大的部位，應優先考慮設計常開式卷簾門。由于常開式有靠電磁釋放閥或磁力門吸、閉門器及自動控制系統來實現自閉的功能，在火災發生時能夠自行迅速關閉，起到防止火災蔓延和煙氣擴散的作用，這樣設計既有利于在火災發生時人員疏散，又能避免經常使用而出現的損壞。

3. The design of normally open rolling shutter door should be given priority in the parts with large daily pedestrian flow and frequent use. Since the normally open type has the function of self closing by means of electromagnetic release valve or magnetic door suction, door closer and automatic control system, it can close itself quickly in case of fire and prevent the spread of fire and smoke. This design is not only conducive to evacuation in case of fire, but also can avoid damage caused by frequent use.

二、安裝規范，質量把關：在安裝濟南卷簾門時，須選用合格的產品，不得降低等級并應嚴格按照規范進行安裝

2、 Installation specification, quality control: in the installation of Jinan rolling shutter door, must choose qualified products, not reduce the level, and should be installed in strict accordance with the specifications

1、安裝門框、門扇時應根據門的開啟方向，向疏散方向開啟。

1. When installing the door frame and door leaf, it should open to the evacuation direction according to the opening direction of the door.

2、門框距四周的墻體不宜過大，必要時應填充水泥砂漿或巖棉進行封堵。

2. The distance between the door frame and the surrounding wall should not be too large. If necessary, it should be filled with cement mortar or rock wool for sealing.

3、避免門框離地面距離過大，若形成門檻則不利于人員疏散。

3. Avoid the door frame from the ground too far, if the threshold is formed, it is not conducive to evacuation.

4、安裝雙扇門時要保證門扇貼合嚴密。

4. When installing the double door, ensure that the door leaf fits tightly.

5、不應自制門框，應購買正規的卷簾門扇進行安裝。

5. Should not be self-made door frame, should buy regular rolling shutter door leaf to install.

6、卷簾門安裝時應注意其是否具備良好的密閉性。

6. When the rolling shutter door is installed, attention should be paid to whether it has good airtightness.

7、堅決杜絕偷工減料，在安裝時更好親自把關。

7. It is necessary to put an end to shoddy work and materials, and better to personally check during installation.

三、管理到位，按時維護：濟南卷簾門作為一種重要的消防設施和常用的防火分隔物在建筑中大量使用，其因保養不善、使用不當造成的損壞經常出現，所以要加強對它的管理和維護。

3、 Management in place, timely maintenance: Jinan rolling shutter door as an important fire-fighting facilities and commonly used fire-proof partition is widely used in buildings, and its damage caused by improper maintenance and improper use often occurs, so it is necessary to strengthen its management and maintenance.

1、杜絕在疏散走道上、防煙樓梯間前室或合用前室設置的常閉式卷簾門在使用過程中人為地使其常開，成為“常開”卷簾門，一旦發生火災，這樣的“常開”卷簾門起不到阻擋煙霧和防火的作用。

1. It is forbidden to make the normally closed rolling shutter door set on the evacuation corridor, the front room of smoke proof staircase or shared front room artificially make it normally open in the process of use, and become "normally open" rolling shutter door. In case of fire, such "normally open" rolling shutter door can not play a role in blocking smoke and fire prevention.

2、經常檢查卷簾門的完好性，查看閉門器、順序器是否好用，卷簾門能否按順序自行關閉，鉸鏈、合頁上的螺絲是否松動，如有損壞應立即組織進行維修。

2. Regularly check the integrity of the rolling shutter door, check whether the door closer and sequencer are easy to use, whether the rolling shutter door can close automatically in sequence, whether the screws on the hinge and hinge are loose, and if there is any damage, repair should be organized immediately.

3、杜絕使用單位片面追求裝飾效果，將卷簾門門框取消而僅設置普通木材制作的門套，將門扇的原有邊框換成其他材料，大范圍加貼裝飾面層，從而破壞防火涂層，起不到防火效果。

3. It is forbidden for the user to pursue the decorative effect unilaterally, cancel the door frame of the rolling shutter door and only set the door pocket made of ordinary wood, replace the original frame of the door leaf with other materials, and paste the decorative surface layer on a large scale, so as to destroy the fire-proof coating and have no fire-proof effect.

4、對常開式卷簾門要定期進行測試，檢查其自行關閉控制系統、閉門器、順序器、釋放開關等方面是否好用，是否能在火災發生時切實地起到自行關閉的功能，同時要堅決防止在常開式濟南卷簾門旁隨意堆放物品。

4. The normally open rolling shutter door should be tested regularly to check whether its self closing control system, door closer, sequencer, release switch and other aspects are easy to use, whether it can effectively play the function of self closing in case of fire, and at the same time, it is necessary to firmly prevent the random stacking of articles near the normally opened Jinan rolling shutter door.
