          Steel construction design FAQ encounter

              First, if you have gutters, tie rod can not be designed to close to the capitals of the site, otherwise it may lead to the installation downspouts. Another gutter downspouts and Tied and inter-column support position must be considered, otherwise either hit Tied either encounter between the column support.
              Second, the level of support arrangement baskets bolt position should be reasonable, not too far from the main beam, you should consider ease of installation based. Otherwise, workers must be installed leaned to tighten bolts or baskets with a ladder up, either end of the installation, such as purlins climb purlins tighten the bolts so very unsafe basket. We would also consider bracing arrangement position, do not fight with bracing in the layout of the level of support.
              Third, do not consider one-sided hole in the pull strip purlins "by the pull side, pressure side" and other factors, ranging from the top and bottom margins hit the hole, because it is very easy to hold against the time of installation, the results detriment.
              Fourth, the doors and windows of the wrap angle plate can not be generalized, because you can not guarantee that in the construction of the plate pressure plate located on the crest or trough.
              Fifth, do large-scale projects, the deepening No. must take into account the production, delivery, installation convenience.
              Six of the Party to provide the "load data such as" we must understand its true meaning, because the Party too often do not understand these professional stuff. We want to achieve empathy, preliminary work done, like follow-up carried out more.
              Seven, the location of high-strength bolts must be reasonable to consider the construction of the space is broken and a torque wrench, not during installation, because the space is too small, can not be broken device and a torque wrench in place, leading to high-strength bolts Torx unable to wring or high-strength bolts can not be tightened. Some designs have come across do not give even the position of the sleeve.
              Eight high-strength bolts connecting plate if possible, as far as possible down the bolts symmetrical arrangement method. There was in contact above 4 below 6, shop workers take part pretend not to accidentally engage in counter, I'm sorry to the scene.
              Nine, if you have to maintain light steel walls, we must advance with the construction and civil engineering construction unit butt good, because it relates to issues of both civil and steel structure, because it is likely to engage in civil brick wall is not straight, color steel pan of water can not possibly do suddenly suddenly small, the results are color plates and wall cracks suddenly suddenly small, difficult to do well when the water pan and wall color plates, allowing the construction units have heart preparation.
              Ten, anchor bolts are generally buried civil units, steel manufacturers a map, they are sometimes able to turn a bolt position 90 degrees, such as the review, it was too late; there to give you a size bias offset 50 ~ 100mm no surprise. So be sure to remind the pre-construction, the best tests, text based (self-protection do).
              XI, wind and steel beam-column connections using a spring-board connector as possible, because the mid-span of the beam installation Deflection relatively large gable beam bolted with the wind if the column will cause uneven roof.
              Twelve, roof purlins layout and detailing steel beams must be carefully checked, often found in the roof purlins and steel beams layout detailing the number of sub-purlins.
              Thirteen, gusset plate without stiffeners, some designers did not design, resulting in subsequent welding, gusset plate deformation.
              Fourth, do Tied beams connecting plate, no holes appropriately extended, in some places because the line is too long rod connecting plate, resulting space is too small, not put into Tied long. Some secondary beam structure often this has happened.
              Fifteen pallets purlin stiffeners direction toward the window when doing stripe windows, so the stripe windows came the ribs, went past. Also when the stripe windows installed to maximize the use of purlins countersunk screws.
              Sixteen, the door on the upper bar window and door frame too, no awning position.
              XVII sash vertically adjacent purlins distance between the brace is not a good layout, brace ends with sash conflict.
              Eighteen, types of steel and high-strength bolts to minimize, to consider the cost of materials testing. Especially when off-site construction, site supervision and some do not recognize the pilot plant. You go to coordinate it?
              Ninth, purlins webs designed as not square easily reversed assembly workshop.
              XX, not in the gutter insulation, interior forming a "cold bridges", resulting in condensation dripping and so on. Should be under the gutter anti-condensation paint brush or spray polyurethane insulation, but also do other thermal insulation.
              XXI, roof using sandwich plate, it is estimated that within six months (if the span is slightly larger) would leak. A check mark off roof outer plate Jidao, because it did not consider the repeated expansion and contraction in the sun. In fact, you at the end of construction (when the sun) you listen to the room to know how it is.
