32、of a door frame, determined in accordance with 6.3, shall not exceed 1,5 mm per metre of length of the member. 3.4 Construction 3.4.1 Door frames a) Door frames shall be made of pressed or roll-formed sheet. Jambs and head members shall have a nominal thickness of, in the case of double rebate profi

33、les for one brick wall (i.e. 230 mm width), at least 1,20 mm and in the case of single rebate profiles for one brick wall, at least 1,60 mm. Amdt 3 SANS 1129:2008 Edition 1.4 8 For half brick walls of thickness ranging from 90 mm to 150 mm (width), single rebate profiles shall be of thickness at lea

34、st 1,20 mm and double rebate profiles shall be of thickness 1,0 mm. Amdt 3 Transoms shall have nominal thicknesses equal to the thicknesses specified for each door jamb as indicated above. Amdt 3 b) Base ties shall be of equal angle section with a leg length of 16 1 mm. They shall be so located that

35、 the bottom of the legs is flush with the lower ends of the jambs (see figure 2). c) Fanlight frames shall be suitable for fixed or opening type fanlights, as specified by the purchaser. In the case of opening type fanlights the fanlight shall be bottom or top hung, as specified by the purchaser (se

36、e figures 3 and 6), and holes, of the size, and located as specified by the purchaser, shall be provided for the attachment of an opening device. In the case of fixed type fanlights, and if so specified by the purchaser, acceptable means for fixing the glazing in position shall be provided. 3.4.2 Fi

37、ttings a) Fixing lugs. Each jamb shall be provided with, in the cases of types 1A and 2A door frames, at least three, and in the cases of types 1B and 2B door frames, at least four fixing lugs. Fixing lugs shall have a nominal thickness and a nominal width of at least 1,20 mm and 25 mm respectively,

38、 and a length such as to have an outstand of at least 150 mm (see figures 2 and 3). Fixing lugs shall be welded centrally to the well of the profiles or, if so specified by the purchaser, shall be supplied loose and shall have an acceptable cross-member (head) for locating the lug between the inner

39、faces of the sides of the profile of each jamb. b) Hinges. Each hinge jamb of a door frame and each transom or head member (as relevant) of a frame for an opening type fanlight shall be fitted with two or (if so specified by the purchaser) more butt hinges. The distances between the transverse centr

40、e-lines of the uppermost and lowest hinges on a hinge jamb and the inside surface of the head member or the transom (as relevant) shall be 200 1 mm and 1 800 1 mm respectively (see figure 2) and, when relevant, additional hinges shall be so positioned that they are equidistant from each other. In th

41、e cases of door frames of types 1A and 1B the hinge jamb shall be suitable for a right-hand door or a left-hand door, as specified by the purchaser (see figure 5). Steel hinges shall be welded or screwed to the door frames (as specified by the purchaser) and brass hinges shall be screwed to the door

42、 frames (see figures 5 and 6). In the case of hinges that are screwed, each hinge shall be screwed to a mild steel reinforcing plate of nominal thickness at least 2,0 mm and of width and length greater than those of the leaf of the hinge. The leaf of each hinge that is attached by welding and each r

43、einforcing plate for hinges attached by screws shall be securely welded to the back surface of the hinge jamb, transom, or head member, as relevant. c) Lock strike plates. The lock jamb of each door frame of type 1A or 1B shall be fitted with an adjustable lock strike plate of nominal thickness at l

44、east 1,20 mm, and suitable for a lock or a latch that complies with the requirements of SANS 4 for the type of lock/latch specified by the purchaser. The lock strike plate shall be screwed in position and shall be capable of being adjusted through a horizontal distance of at least 5 mm. The vertical

45、 distance between the transverse centre-line of the lock strike plate and the lower end of the jamb shall be not less than 1 150 mm and not more than 1 200 mm (see figure 2). SANS 1129:2008 Edition 1.4 9 d) Shock absorbers. Each lock jamb of door frames of types 1A and 1B shall have two shock absorb

46、ers, inserted in holes in the 12 mm wide face of the rebate and positioned at approximately the same level as the midpoints of the uppermost and lowest hinges (see figure 2). 3.5 Welded joints The welding of all welded joints shall be such that it is acceptable. The profiles of the welds shall merge

47、 smoothly into the adjacent surfaces of the parent metal without excessive undercut or overlap. The weld faces shall be reasonably uniform and free from excessive porosity, cavities, and trapped slag and, in the case of surfaces that will be exposed in service, shall have been finished flush with th

48、e parent metal. In butt welds there shall be adequate root penetration. All weld metal, heat affected zones, and the adjacent parent metal shall be free from cracks. 3.6 Finish of steel surfaces NOTE Fittings of a material other than mild steel need not have a coating of any type. 3.6.1 General The

49、surfaces of all components of door frames and fittings (other than lock strike plates) that are made of mild steel shall have a painted, galvanized, or sprayed zinc or aluminium coating that complies with the requirements given in 3.6.2-3.6.4 relevant to the type of coating specified by the purchaser. All surfaces shall, before coating, be clean and free from weld spatter, loose scale, flux, grease, oil, and other foreign matter. In the case of stainless steel lock strike plates, the exposed surfaces shall have a bright polished or a matt finish, as specified by
