膨胀螺丝钉的原理
The principle of expansion screws)
膨胀螺丝钉的原理是把膨胀螺栓打到地面或墙面上的孔中后,用扳手拧紧膨胀螺丝上的螺母,螺丝往外走,而外面的金属套却不动,于是,螺栓底下的大头就把金属套涨开,使其涨满整个孔,此时,膨胀螺丝就抽不出来了。
The principle ofexpansionbolts is to put the bolts to the ground or in the hole on the wall, using a wrench, tighten the screw the nut on the screw go toward outside walk, outside, metal sleeve is fixed, so under the bolt head just jumped the metal sleeve and make it suffuse the whole hole, at this point, the anchors are not to come out.
膨胀螺丝钉的固定是利用挈形斜度来促使膨胀产生摩擦握裹力,达到固定效果.螺钉一头是螺纹,一头有椎度。
Expansionscrews fixation is using Qie form slope to push inflation friction grip of, fixed effect. A screw head is thread, a have a job.
外面包一铁皮,铁皮圆筒一半有若干切口,把它们一起噻进墙上打好的洞里,然后锁螺母,罗母把螺钉往外拉,将椎度拉入铁皮圆筒,铁皮圆筒被涨开,于是紧紧固定在墙上,一般用于防护栏、雨蓬、空调等在水泥、砖等才料上的紧固。
Outside a tin, tin drum half number of incision, consult them together into a good hole in the wall, then lock nut, strong technical strength to pull the screw out, pull vertebral degrees into the tin drum, tin drum is open, so firmly fixed on the wall, is generally used in fence, rain loose, air conditioning in the cement, brick, etc, such as the fastening.
但它的固定并不十分可靠,如果载荷有较大震动,可能发生松脱,因此不推荐用于安装吊扇等。
But its fixed is not very reliable, if there is a bigger shock load, may be loose, therefore is not recommended for installation of ceiling fans, etc.
膨胀螺钉现在有不锈钢膨胀螺钉和塑料膨胀螺钉之分,具体用途不一样。
Expansionscrews now have stainless steel screws and plastic expansion screws, specific purposes.
膨胀螺丝钉的用途
The purpose of the expansion screws
膨胀螺丝钉的用途很广泛,大到工地工程,小到家居装饰,一般是打入墙上或地面。
Expansionscrews USES is very wide, big to site work, small to home decoration, usually into the wall or the ground.
比幕墙、防护栏、雨蓬、空调等等。
Than the curtain wall, fence, rain loose, air conditioning and so on.

膨胀螺丝钉的组成
The composition of expansion screws
膨胀螺丝钉由沉头螺栓,胀管、平垫圈、弹垫圈和六角螺母组成,使用时须先用冲击电钻在固定体钻出相应尺寸的孔,再把螺栓、胀管装入孔中,旋紧螺母即可使螺栓、胀管、安装件与固定体之间胀紧成为一体。
Expansion screwsby countersunk head bolts, expansion tubes, flat washer, spring washer and the hexagonal nut, must use first when using impact electric drill in the fixed body out corresponding size of the hole, then put the bolts, expansion pipe into the hole, can make screw nut bolts, expansion tube, install a bulge between the fixed body as a whole.
拧紧以后会膨胀的,螺栓尾部有一个头,螺栓外面套管委会比螺栓直径稍大的圆管子,尾部那部分有几道开口,当螺栓拧紧后,大头的尾部就被带到开口的管子里面,把管子冲大,达到膨胀的目的,进而把螺栓固定在地面或墙壁上,达到生根的目的。
Tighten the expansion of the will, the bolt has a head, tail bolt set outside the ac slightly larger than the diameter of a bolt circle tube, and the tail part that there are a few openings, when the bolt is tightened, the bulk of the tail was brought to the opening of the pipe, the pipe burst, achieve the purpose of expansion, and then put the bolt fixed on the ground or walls, achieve the purpose of rooting.

膨胀螺丝的安装方法及注意点
Screw installation method and attention points
1、钻孔深度:相关资料介绍的是膨胀管的长度,但我们在具体施工中发现这个深度不够,可能给孔内杂物残留量有关,所以你最好还是比膨胀管的长度深5毫米左右。
: 1, drilling depth related data is the length of the expansion pipe, but we found the depth in concrete construction, may be associated to sundry residues in the hole, so you\'d better than the length of the expansion pipe about 5 mm deep.
只要你大于或等于了膨胀管的长度,那么留在地下的膨胀螺栓的长度等于或小于膨胀管的长度。
As long as you is greater than or equal to the length of the expansion pipe, so stay in underground expansion bolt length is equal to or less than the length of the expansion pipe.
2、钻孔直径:M6系列钻孔直径为10mm,M8系列钻孔直径为12mm
2, the hole diameter: M6 series hole diameter of 10 mm, M8 series hole diameter is 12 mm
M10系列钻孔直径为14mm,M12系列钻孔直径为16mm
M10 series hole diameter is 14 mm, M12 series hole diameter is 16 mm
M14系列钻孔直径为18mm,M16系列钻孔直径为20mm
M14 series of 18 mm in diameter, drilling series M16, the hole diameter for 20 mm
M20系列钻孔直径为24mm
M20 series of borehole diameter 24 mm
3、膨胀螺栓对地面的要求当然是越硬越好,这也要看你需要固定的物件受力情况。
3, expansion bolts on the ground is as hard as possible, of course, it also depends on the force situation you need fixed objects.
安装在混凝土中的受力强度是在砖体中的五倍。
Installed in the concrete stress intensity is five times in the brick.
4、正确安装在混凝土中的一颗M6/M8/M10/M12的膨胀螺栓后,它的最大静止受力分别是120kg/170kg/320kg/510kg。
4, correct installation in the concrete of a M6 / M8 / M10 / M12 bolts, its maximum static stress, respectively is 120 kg / 170 kg / 320 kg / 510 kg.
