濟南卷簾門維修的時候,經常會遇到幾個問題,這就需要大家要多了解,下麵就一起來了解下卷簾門大致存在著幾個方麵的問題。
Jinan roller shutter door maintenance, often encounter several problems, which requires us to understand more, the following together to understand the next roller shutter door there are some problems.
1、卷簾門門簾厚度問題:門簾厚度即簾板所用鋼板的厚度,目前普遍存在著偷工減料現象,有些廠家送交測試時采用較厚鋼板的簾板,取得合格證後,則改用較薄的進行生產,由於在安裝現場卷簾門的簾板厚度不易測量,容易蒙混過關,因此,有很多卷簾門因門簾厚度都未達到要求,降低使用壽命與耐火時限。
1. The thickness of rolling shutter door curtain: the thickness of the curtain is the thickness of the steel plate used for the curtain plate. At present, there is a phenomenon of Jerry building. Some manufacturers use the thicker steel plate curtain plate when they send it for testing. After obtaining the certificate of conformity, they use the thinner one for production. Because the thickness of the curtain plate of the rolling shutter door on the installation site is not easy to measure, it is easy to muddle through. Therefore, there are many rolling shutter doors because of the curtain The thickness does not meet the requirements, reducing the service life and fire resistance time.
2、卷簾門預卷問題:按常規當門簾放到底時,上部在簾軸應留一圈門簾,以減少門簾重量對螺釘處的拉力,防止一塊簾板破裂,但現在的卷簾門普遍沒有做到這一點,由於簾卷都在吊頂裏麵,驗收時無法覺察,使用時間久後有整簾掉下的危險,後患無窮。
2. Pre rolling problem of rolling shutter door: according to the routine, when the curtain is placed to the end, a circle of curtain shall be reserved on the upper part of the curtain shaft to reduce the tension of the weight of the curtain on the screw and prevent the rupture of a curtain plate. However, the rolling shutter door generally fails to do this at present, because the curtain rolls are all in the ceiling, which cannot be detected during the acceptance, there is a risk that the whole curtain will fall down after a long time of use, and there will be endless troubles.

3、卷簾門門楣結構問題:濟南卷簾門按國家標準卷簾門須設置門楣結構,門楣處的密封性是防火、防煙的關鍵所在,若安裝沒有門楣結構的卷簾門,則不能起到防火阻隔的作用,形同虛設,而目前普遍使用的是沒有門楣的卷簾門,這種門發生火災時阻止不了火勢向上形成的強大衝擊,導致煙氣通過門楣向外蔓延。
3. Structural problems of the lintel of roller shutter door: according to the national standard, the lintel structure must be set in Jinan roller shutter door. The sealing of the lintel is the key to fire prevention and smoke prevention. If the roller shutter door without lintel structure is installed, it can't play the role of fire prevention and barrier. It's like a virtual device. At present, the roller shutter door without lintel is widely used, which can't prevent the fire direction in case of fire The strong impact formed on the top causes the smoke to spread outwards through the lintel.
4、卷簾門門簾底梁問題:有的產品沒有底梁,有的產品雖有底梁,但用料單薄,門簾的底梁是保持門簾強度重要構件,門簾下沒有底梁就等於門簾下部少一個起堅固作用的邊框,火場負壓就會將整個門簾掀翻。
4. The problem of bottom beam of roller shutter door curtain: some products have no bottom beam, while some products have a bottom beam, but the material is thin. The bottom beam of the curtain is an important component to maintain the strength of the curtain. If there is no bottom beam under the curtain, it means that there is less a solid frame under the curtain, and the negative pressure of the fire will overturn the whole curtain.
5、卷簾門導軌問題:導軌深度不夠,結構與用料不當是許多大型卷簾門安裝中普遍存在的問題,大型卷簾門導軌上一般應有一根能承受高強度的主構件,然而很多廠商用簡易的輕型導軌來代替,一旦遇到火災,門簾易從導軌脫出,起不到防火作用。
5. The problem of rolling shutter door guide rail: insufficient depth of guide rail, improper structure and material are common problems in the installation of many large rolling shutter doors. Generally, there should be a main component that can bear high strength on the guide rail of large rolling shutter doors. However, many factories use simple light guide rail to replace it. Once a fire occurs, the curtain is easy to get out of the guide rail, which does not play a role in fire prevention.
6、卷簾門卷簾軸的強度問題:卷簾軸強度也是卷簾門的一個重要參數,目前這種強度不合格的產品很多,嚴重影響了卷簾門的使用,卷簾軸的結構主要指卷簾軸兩端軸頭塞人鋼管內的深度及其結構,軸頭塞人深度應為軸長的1/10左右,且要有兩個法蘭和足夠的焊縫,有些廠商的產品卻塞入很短,甚至用一個法蘭,這種偷工減料的門使用一段時間後有斷裂的危險。
6. Strength of roller shutter shaft: the strength of roller shutter shaft is also an important parameter of roller shutter door. At present, there are many unqualified products, which seriously affect the use of roller shutter door. The structure of roller shutter shaft mainly refers to the depth and structure of the shaft plug at both ends of the roller shutter shaft into the steel pipe. The shaft plug depth should be about 1 / 10 of the shaft length, and there should be two flanges and enough welds , some manufacturers' products are stuffed in a short time, even with a flange. This kind of door with Jerry built materials may break after being used for a period of time.
7、濟南卷簾門傳動鏈條問題:傳動鏈條一般由卷門機製造廠按卷門機的提升重量生產,並隨卷門機一同配來,目前一些卷門窗幕牆簾門所配鏈條普遍嫌小,卷簾 門都存在著斷裂的可能,按常規標準,卷簾門應當有斷鏈安.全裝置,而實際上許多門沒有這方麵的裝置,因而存在不安.全的隱卷簾門患。
7. Jinan rolling shutter door drive chain problem: the drive chain is generally produced by the rolling machine manufacturer according to the lifting weight of the rolling machine, and is matched with the rolling machine. At present, the chain of some rolling doors, windows, curtain walls, curtain doors is generally too small According to the conventional standard, the rolling shutter door should have the safety device of broken chain. In fact, many doors do not have such a device, so there is a problem of uneasy and safe hidden rolling shutter door.

8、卷簾門軸承、軸承架與卷門機的問題:卷簾軸、軸承架與卷門機的安裝不規範,不統一,大部分製造卷簾門的工廠沒有正規的圖紙,沒有正規的技術工人,也是一個急待解決的問題。
8. The problems of roller shutter bearing, bearing frame and rolling machine: the installation of roller shutter shaft, bearing frame and rolling machine is not standardized and unified. Most of the factories that manufacture roller shutter do not have regular drawings and technical workers, which is also an urgent problem to be solved.
9、卷簾門斷電時手動快速關閉裝置的傳動問題:火災中,如發生電源中斷,現場人員可采用手動速放裝置,將門關閉,現在有一部分卷簾門沒裝這種裝置,即使裝了,也往往因質量問題,不起作用。
9. Transmission problem of the manual quick closing device when the rolling shutter door is powered off: in case of power interruption in the fire, the field personnel can use the manual quick release device to close the door. Now some rolling shutter doors are not equipped with this device, even if it is installed, it often fails to work due to quality problems.
10、卷簾門火災溫度控製關門問題:國標規定,在卷簾門2米範圍內,當火災發生,電源中斷,現場無人操作時,應當有火勢溫度熔斷控製關門裝置,這個功能特別對人員密集場所更顯重要,但現在尚不見這類裝置。
10. Shutter door fire temperature control door closing problem: according to the national standard, when the fire occurs, the power supply is interrupted, and no one is operating on site, there should be a fire temperature fuse control door closing device. This function is particularly important for densely populated places, but such devices are not yet available.
目前市場上塑料異型材產量雖然很大,濟南卷簾門但有一個共同點,即均為白色,色調單一,不能適應建築牆麵裝飾多樣化的要求。
At present, although the output of plastic profile in the market is very large, Jinan roller shutter door has one thing in common, that is, they are all white with single color, which can not meet the requirements of diversified wall decoration.
