如今輕型鋼結(jié)構(gòu)已得到了較為廣泛的應(yīng)用。與此同時(shí)，建筑鋼材、連接技術(shù)及加工、安裝技術(shù)也進(jìn)一步達(dá)到了系列配套的要求。下面來講講濟(jì)南輕型鋼結(jié)構(gòu)檁條、支撐等構(gòu)件的制作安裝事項(xiàng)！

Nowadays, light steel structure has been widely used. At the same time, construction steel, connection technology, processing and installation technology also further meet the requirements of a series of supporting facilities. Now let's talk about the fabrication and installation of Jinan light steel structure purlins, supports and other components!

1、為了安裝方便，隨意增大、加長檁條或檁托板的螺栓孔徑。檁條不僅僅是支撐屋面板或懸掛墻面板的構(gòu)件，而且也是剛架梁柱隅撐設(shè)置的支撐體，設(shè)置一定數(shù)量的隅撐可減少剛架平面外的計(jì)算長度，有效的保證了剛架的平面外整體穩(wěn)定性。若檁條或檁托板孔徑過大過長，隅撐就失去了應(yīng)有的作用。

1. For the convenience of installation, the bolt hole diameter of purlin or purlin support plate shall be increased or lengthened at will. Purlins are not only the components supporting roof panels or suspended wall panels, but also the supports set by corner braces of rigid frame beams and columns. Setting a certain number of corner braces can reduce the calculated length of rigid frames out of plane, effectively ensuring the overall stability of rigid frames out of plane. If the hole diameter of purlin or purlin supporting plate is too large and too long, the corner brace will lose its due role.

2、隅撐角鋼與鋼梁的腹板直接連接，當(dāng)剛架受側(cè)向力時(shí)，使腹板在該處局部受到側(cè)向水平力作用，容易導(dǎo)致鋼梁局部側(cè)向失穩(wěn)。

2. The corner brace angle steel is directly connected with the web of the steel beam. When the rigid frame is subjected to lateral force, the web will be locally subjected to lateral horizontal force at this location, which is easy to cause local lateral instability of the steel beam.

3、有的工程所用檁條僅用電鍍，造成工程尚未完工，檁條早已生銹。檁條宜采用熱鍍鋅帶鋼壓制而成的檁條，且保證一定的鍍鋅量。

3. Purlins used in some projects are only electroplated, resulting in that the project has not been completed and the purlins have already rusted. Purlins should be made of hot-dip galvanized strip steel, and a certain amount of galvanizing should be guaranteed.

4、因墻面開設(shè)門洞，擅自將柱間垂直支撐一端或兩端移位。同一區(qū)隔的柱間支撐、屋面水平支撐與剛架形成縱向穩(wěn)定體系，若隨意移動(dòng)其位置將會(huì)破壞其穩(wěn)定體系。

4. One or both ends of the vertical support between columns shall be displaced without authorization due to the door opening on the wall. The column bracing, roof horizontal bracing and rigid frame of the same partition form a longitudinal stability system. If their positions are moved randomly, their stability system will be destroyed.

5、有些單位為了節(jié)省鋼材和人工，將檁條和墻梁用鋼板支托的側(cè)向加勁肋取消，這將影響檁條的抗扭剛度和墻梁受力的可靠性。故施工單位不得任意取消設(shè)計(jì)圖紙的一些做法。

5. In order to save steel and labor, some units cancel the lateral stiffeners supported by steel plates for purlins and wall beams, which will affect the torsional stiffness of purlins and the reliability of wall beams. Therefore, the construction unit shall not arbitrarily cancel some practices of design drawings.

6、有的單位擅自增加屋面荷載，原設(shè)計(jì)未考慮吊頂或設(shè)備管道等懸掛荷載，而施工中卻任意增加吊頂?shù)葢覓旌奢d，從而導(dǎo)致鋼梁撓度過大或坍塌。任何單位均不得擅自增加設(shè)計(jì)范圍以外的荷載。

6. Some units increase the roof load without authorization. The original design did not consider suspended loads such as suspended ceilings or equipment pipes, but they arbitrarily increase suspended loads such as suspended ceilings during construction, resulting in excessive deflection or collapse of steel beams. No unit shall increase the load beyond the design scope without authorization.

7、屋面板未按要求設(shè)置，將固定式改為浮動(dòng)式，使檁條側(cè)向失穩(wěn)。往往設(shè)計(jì)檁條時(shí)，會(huì)考慮屋面壓型鋼板與冷彎型鋼檁條牢固連接，能可靠的阻止檁條側(cè)向失穩(wěn)并起到整體蒙皮作用。

7. The roof panel is not set as required, and the fixed type is changed to the floating type, which causes lateral instability of the purlin. When designing purlins, the roof profiled steel plate and cold-formed steel purlins will be firmly connected, which can reliably prevent the lateral instability of purlins and play the role of integral skin.

8、剛性系桿、風(fēng)拉桿的連接板設(shè)置位置高低不一，使得水平支撐體系不在同一平面上，從而影響剛架的整體穩(wěn)定性。剛性系桿與風(fēng)拉桿構(gòu)成水平支撐體系，其設(shè)置高度在同一坡度方向應(yīng)保持一致。

8. The connecting plates of rigid tie rods and wind pull rods are set at different positions, which makes the horizontal support system not on the same plane, thus affecting the overall stability of the rigid frame. The rigid tie rod and wind pull rod form a horizontal support system, and their setting heights shall be consistent in the same slope direction.

當(dāng)今鋼結(jié)構(gòu)隊(duì)伍素質(zhì)良莠不齊，時(shí)有“家庭作坊”式的鋼結(jié)構(gòu)隊(duì)伍充斥其中，對(duì)一般鋼結(jié)構(gòu)加工及安裝知識(shí)了解甚少，致使在一些工程中發(fā)生工程質(zhì)量隱患和質(zhì)量事故，所以這就要您有需求找施工隊(duì)伍時(shí)要多加對(duì)比多加考慮了，更多相關(guān)鋼結(jié)構(gòu)的事情就來我們網(wǎng)站http://qzone9781.cn咨詢吧！

Nowadays, the quality of steel structure teams varies from good to bad. There are always "family workshop" steel structure teams. They know little about the general steel structure processing and installation knowledge, which leads to engineering quality hazards and quality accidents in some projects. Therefore, you need to compare and consider more when looking for construction teams. More relevant steel structure matters will come to our website http://qzone9781.cn Consult!
