Bracket type 765

Bracket type 765 is a bracket fitted between a profile or plate in cross section and a profile in plan view. The dimensions are calculated according to the profile height. If the span length is bigger than 475 mm, the system automatically adds a flange of 75 mm.

Relation

Question

Selection criterion

First

Indicate profile at position where overlap has to be placed

Profile in plan view

Second

No, see Third

Plate or bracket in section, hull line

Third (Second)

Indicate profile/plate in section, where bracket stops

Plate or bracket in cross section, profile or face plate in cross section.

The second relation is selected automatically.

R variable

Default

Question

R1

Calculated from height of profile

Enter height of bracket
     

D

SelCri[4]='CSPROFILE,CSPLATE'

SelText[1] = 2

SelText[2] = S

SelText[4] = 18

exit

The second SelText is defined with a S. This means that the system will search for a second part using the first point.

if HP[1]<>0 then

{

 if abs(HpGap[1] Def_Par_Dist)>3 :Ans[1]=Def_HP_fact*HP[1]+HpGap[1];

}

if DP[1] > DP[4]  : Ans[2]=DP[4] ;

else Ans[2]=DP[1]

CornerValue=0.25*HP[4]

exit

The height is taken from the HP[1] variable which is the height of the profile. If it is related to a plate the height is zero. If the gap between the profile in plan view and the plate in cross section is bigger than the default gap distance (Def_HP_Par), R1 is calculated by (profile heigth * 1.25 + Def_par_Dist).

The thickness of the bracket is the same than the smaller of the two profiles.

Gef_HP_fact is by default 1.25 but can be changed by the system manager.

else notify t=ERR;'The thickness of the bracket is to big !!';

}

exit

The bracket gets panel code YA.

BracketNumber is dependent on BulbSide. If the bracket is connected to the bulb side, the type is 765a otherwise it is 765.

A flange will be added if the length is bigger than 475 mm. The user can also select to add a flange. The RigRad variables are used for temporary storage.
