作業(yè)準(zhǔn)備—選擇螺栓并配套—接頭組裝—安裝臨時(shí)螺栓—安裝高強(qiáng)螺栓—高強(qiáng)螺栓緊固—檢查驗(yàn)收
Operation preparation - selecting bolts and matching - joint assembly - installing temporary bolts - installing high-strength bolts - fastening high-strength bolts - inspection and acceptance
螺栓長(zhǎng)度的選擇:扭剪型高強(qiáng)螺栓的長(zhǎng)度為螺栓頭根部螺栓梅花卡頭切口處的長(zhǎng)度。選用螺栓的長(zhǎng)度應(yīng)為緊固連接板厚度加上一個(gè)螺母和一個(gè)墊圈的厚度，并且緊固后要露出不少于兩扣螺紋的余長(zhǎng)，一般按連接板厚加表5-2中的增加長(zhǎng)度，并取5mm的整倍數(shù)。
Selection of bolt length: the length of the torsional shear type high-strength bolt is the length from the root of the bolt head to the notch of the bolt quincunx. The length of the selected bolt shall be the thickness of the fastening connecting plate plus the thickness of one nut and one washer, and the surplus length of not less than two threads shall be exposed after fastening. Generally, the thickness of the connecting plate plus the increased length in Table 5-2 shall be taken as an integral multiple of 5mm.
扭剪螺栓就是鋼結(jié)構(gòu)螺栓，也屬于高強(qiáng)度螺栓，也是標(biāo)準(zhǔn)件的一種。而了解鋼結(jié)構(gòu)螺栓主要看鋼結(jié)構(gòu)螺栓分類、施工。如果你是外行，如有需要用到這些配件的時(shí)候一定要提前了解一下相關(guān)知識(shí)，只有這樣才不會(huì)選錯(cuò)產(chǎn)品。今天就隨天圣小編來(lái)看看鋼結(jié)構(gòu)螺栓解析，以供大家參考。
Torsional shear bolt is a kind of steel structure bolt, which is also a high-strength bolt and a standard part. The understanding of steel structure bolts mainly depends on the classification and construction of steel structure bolts. If you are a layman, if you need to use these accessories, you must know the relevant knowledge in advance, so that you can not choose the wrong product. Today, we will take a look at the comprehensive analysis of steel structure bolts with Tiansheng small editor for your reference.
一、鋼結(jié)構(gòu)螺栓運(yùn)用
1、 Application of steel structure bolts
鋼結(jié)構(gòu)螺栓主要應(yīng)用在鋼結(jié)構(gòu)工程上,用來(lái)連接鋼結(jié)構(gòu)鋼板的連接點(diǎn)。鋼結(jié)構(gòu)螺栓是一種高強(qiáng)度的螺栓，也是標(biāo)準(zhǔn)件的一種。緊固性能比較好，用于鋼結(jié)構(gòu)上，工程上，使緊固作用的。一般鋼結(jié)構(gòu)上，要求的鋼結(jié)構(gòu)螺栓都是8.8級(jí)以上的，還有10.9級(jí)，12.9級(jí)的，全部都是高強(qiáng)度的鋼結(jié)構(gòu)螺栓，有時(shí)鋼結(jié)構(gòu)上的螺栓是不需要電鍍的，用本色就OK。
Steel structure bolts are mainly used in steel structure engineering to connect the connection points of steel structure plates. The steel structure bolt is a kind of high-strength bolt and also a standard part. The fastening performance is relatively good. It is used for steel structure and engineering to ensure the fastening effect. For general steel structures, all required steel structure bolts are above Grade 8.8, as well as Grade 10.9 and 12.9, all of which are high-strength steel structure bolts. Sometimes the bolts on steel structures do not need electroplating, and it is OK to use the natural color.
二、鋼結(jié)構(gòu)螺栓分類
2、 Classification of steel structure bolts
鋼結(jié)構(gòu)螺栓分為扭剪型高強(qiáng)螺栓和大六角高強(qiáng)螺栓,大六角高強(qiáng)螺栓屬于普通螺絲的高強(qiáng)度級(jí),而扭剪型高強(qiáng)螺栓則是大六角高強(qiáng)螺栓的改進(jìn)型,為了更好施工。
The steel structure bolts are divided into torsional shear high-strength bolts and large hexagon high-strength bolts. The large hexagon high-strength bolts belong to the high strength level of ordinary screws, while the torsional shear high-strength bolts are improved types of large hexagon high-strength bolts for better construction.
三、鋼結(jié)構(gòu)螺栓施工
3、 Steel structure bolt construction
鋼結(jié)構(gòu)螺栓的施工需要先初緊后終緊,初緊鋼結(jié)構(gòu)螺栓需用沖擊型電動(dòng)扳手或扭矩可調(diào)電動(dòng)扳手;而終緊鋼結(jié)構(gòu)螺栓有嚴(yán)格的要求,終緊扭剪型鋼結(jié)構(gòu)螺栓需要用扭剪型電動(dòng)扳手,終緊扭矩型鋼結(jié)構(gòu)螺栓需要用扭矩型電動(dòng)扳手。
The construction of steel structure bolts requires initial tightening before final tightening, and the initial tightening of steel structure bolts requires impact type electric wrench or torque adjustable electric wrench; The final tightening of steel structure bolts has strict requirements. The final tightening of torsional shear type steel structure bolts requires the use of a torsional shear type electric wrench, and the final tightening of torque type steel structure bolts requires the use of a torque type electric wrench.
The above is a detailed introduction of the special wrench for torsional shear bolts, and I hope it will be helpful to you. If you have any questions, please contact us. We will provide you with professional services http://laddervpn.cn
