The arrangement of purlins on the wall is the same as that on the roof. The curtain layout of the wall should first consider the requirements of doors and windows and other accessories, and comprehensively consider the types and specifications of plates to determine the distance between the walls, flashing plates and fence materials. The pudding span on the wall depends on the column spacing of the main rigid frame. If the column spacing is too large, the wall frame columns can be set by making the wall pudding uneconomical. The configuration of wall pudding for wall purlins is generally consistent with doors and windows. There are two kinds of relative positions between the wall nail and the main column. The free flange of the wall purlin is connected to the outer flange of the column or to the bracket only by bolts. According to the overlapping length of the wall, determine whether the wall pudding is continuous or simply supported.

Flash, that is, the pudding on the wall is connected to the column. Use flash wall layout. The arrangement of wall purlins is connected with the columns of the main frame only by connecting plates. Prince Gibbs doesn't need an extra joint plate. The foundation angle steel is connected with the outer edge of the column to reduce the width of the foundation.

Wall purlins provide options for cold-formed thin-walled puddings designed according to door rules and cold-formed thin-walled specifications. If the verification threshold is selected, the Frankie stability check program under the exhaust fan will provide two options.

The selection principle of wall purlin is as follows: profiled steel plate layer (thickness > 50? Mm), the roof and pudding have a highly reliable connection (self-timer screws and other zippers), a single-layer circuit breaker is set near the upper flange, and a door slot is provided to do something according to E calculation. For wall purlins, for roofs with weak rigidity (plastic tiles, etc.), the specification of 6.6.7-2 or cold bending shall be adopted. ) and stamped steel plate with uncertain connection (seat bending, etc.). ), and the selected compression effect is set according to Bruce's actual situation. For the area with large wind load in wall purlin, it is suggested to set double-layer circuit breaker, cross circuit breaker or section steel circuit breaker, which can restrain the upper and lower flanges at the same time. If the attraction of the wind cannot be controlled, a single-layer valve can be set on it.
