Steel structure design to solve structural problems of common problems to solve other problems.




One, if there is a gutter, tied not to cling to the top part, or may lead to installation of the water pipe.In addition the gutter downspouts and tied and the column brace position must consider well, otherwise either tied or meet, meet braces between columns.

In two, steel structure warehouse strength bolt position must be reasonable, steel structure engineering should consider twisting device and a torque wrench construction space, not at the time of installation, because the space is too small, twisting device and a torque wrench can not in place, resulting in high strength bolts plum head to break or to tighten high strength bolts.Once met some design and the position of the sleeve will not give.Three, the party's "load data" must understand its true meaning, because the party often do not understand these things too specialized.We should accomplish transposition thinking, preliminary work done, follow-up is well developed.In four, high strength bolt connecting plate if possible, steel structure housing as a symmetrical upper and lower bolt layout method.Once in contact above 4 to below 6, shop workers take part installed do not care to be reversed, at the site of sorry to.Five, wind-resistant column and steel beam connection as a spring board connection, because the middle cross beam after the installation of deflection is bigger, Liang Ruo of bolts and wind-resistant column connection, will cause the roof.

Six, do not one-sidedly in purlin brace hole on account of "tension side pressure side," and other factors, hit the top and bottom margins ranged from the hole, because the installation is easily reversed, but the results of adverse.

In seven, a horizontal support a flower basket bolt location arrangement must be reasonable, do not stray too far from a girder, should consider convenient installation.Otherwise, workers in the installation must be bent to tighten the screw bolt or ladder up, or after the purlins mounted climb purlin tightening screw bolt which is not safe.In addition to consider brace layout position, not in the layout of horizontal strut and bracket.

Eight, windows and doors of angle plates can lump together in construction, because you could not guarantee that plate in the pressure plate crest or trough.

Nine, do bar window apron plate stiffener toward the window direction, so the bar window to the floor, do not go past.In the bar the purlins mounted window to use countersunk head screws.

In ten, the anchor bolts are steel structure warehousegenerally buried civil unit, manufacturer of steel structures of a map, they can sometimes turn bolt location turned 90 degrees, and reexamination, it was too late; and size deviation give you an offset of 50~100mm is not strange.So in the former construction must be reminded, preferably clarification on the basis of language (self protection).In eleven, large project, deepen the figure number must take into account the production, delivery, installation convenience.

Twelve, roof purlin layout and steel detailing should check seriously, often found roof purlin layout and steel detailing the purlin number disagreement.

In thirteen, the node board without stiffening ribs, some designers are not designed for, leading to subsequent welding, node plate deformation.

Fourteen, beam column do tie connecting plate, no holes extended in some places appropriate, because the tie-bar connecting plate on too long, resulting in too small space, tied too long to fit inside.Some secondary beam structures often have this case.In fifteen, light steel structure if maintenance brick wall, must advance with the construction unit and construction unit butt good, because it relates to the construction of steel structure and the problem of two respects, because civil brick probably do not straight, but the color steel plate flashing and could not do suddenly large and small, the result is the color steel and brick wall crack suddenly large and small, color steel plate and the brick wall water treatment is very difficult to do well, make construction unit of a prepared mind.

In sixteen, the upper bar window and door frame too close, no room for Hupon.

In seventeen, the window frame adjacent purlin distances without brace layout, bar end head and the window frame conflict.
