Restriction in case of certain storeys. height of one storey, 26 inches thick for the height of the next storey, 17 inches thick for the next three storeys, and 13 inches for the rest of the height of the wall, instead of 21 inches for the first two storeys, 17 inches for the next three storeys, and 13 inches for the remainder. The provisions as to the distribution of the thickness of walls in piers will be found in Rule 3 of the Miscellaneous Rules, post, p. 310. For an illustration of this rule, see Diagram VIII., Pl. XIII., Appendix V., post. 9. Where the wall exceeds one hundred feet but does not exceed one hundred and twenty feet in height its thickness shall be as follows: · If the wall does not exceed forty-five feet in length it shall Note. This rule is new, as no provision was made by the Metropolitan Building Act, 1855, in respect of walls exceeding one hundred feet in height. The distribution of the thickness of walls in piers is provided for by Rule 3 of the Miscellaneous Rules, post. For an illustration of this rule, see Diagram IX., Pl. XIII., Appendix V., post. 10. If any storey exceeds in height sixteen times the thickness prescribed under this Schedule for the walls of such storey the thickness of each external and party wall throughout such storey shall be increased to one sixteenth part of the height of the storey and the thickness of each external and party wall below that storey shall be increased to a like extent but any such additional thickness may be confined to piers properly distributed of which the collective widths amount to one fourth part of the length of the wall. Note. This rule is the same as the corresponding rules in Part I. of the Schedule to the Metropolitan Building Act, 1855, except that the words printed in italics have been introduced here for the first time. With regard to the distribution of the thickness of walls in piers, see also Rule 3 of the Miscellaneous Rules, post. 11. No storey enclosed with walls less than thirteen inches in thickness shall be more than ten feet in height between the floor and the ceiling thereof or between the floor and the tie of the roof. Note. The words printed in italics have been added to the rule 6 in Part I. of the Schedule to the Metropolitan Building Act, 1855, with which the present rule is otherwise identical. The tie of the roof is a beam or rod by which the ends of the rafters are connected so as to prevent them from thrusting out the walls of the building. Sch. I., Pt. II. r. 1-3. 12. All buildings excepting public buildings and such 57 & 58 Vict buildings as are in this Act defined to be buildings of the warehouse class shall as respects the thickness of their walls be subject to the provisions contained in this part of this Schedule. Note. This rule is the same as the corresponding rule 8 in Part I. of the Schedule to the Metropolitan Building Act, 1855, except that reference to the provisions of the present Act has been substituted for the reference to the Act of 1855 in the former rule. Rule as to build Ings not being public buildings or buildings of the warehouse class. PART II. BUILDINGS OF THE WAREHOUSE CLASS. The external and party walls of buildings of the warehouse Thickness at class shall at the base be made of not less thickness than the base. thickness hereinafter specified in each case viz : Buildings of the warehouse class.-This expression is defined by sect. 5 (28), ante, p. 25, as meaning warehouses, factories, manufactories, breweries, or distilleries, and any other buildings exceeding in cubical extent one hundred and fifty thousand cubic feet, which are neither public buildings [as to which, see sect. 5 (27), ante, p. 24] nor domestic buildings [as to which, see sect. 5 (26), ante, p. 24]. External and party walls.—These expressions are respectively defined by subsects. 15 and 16 of sect. 5, ante, p. 17. 1. Where the wall does not exceed twenty-five feet in height (whatever is its length) it shall be thirteen inches thick at its base. Note. This rule is the same as the rule in the Act of 1855, which regu lated the thickness of the walls of buildings of the warehouse class which did not exceed 25 feet in height. See Diagram I., Pl. XIV., Appendix V., post. 2. Where the wall exceeds twenty-five feet but does not exceed thirty feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall be thirteen inches thick at its base; If the wall exceeds forty-five feet in length it shall be seventeen and a half inches thick at its base. Note. The rule also is the same as the corresponding rule in the Act of 1855. For an illustration of the rule, see Diagram II., Pl. XIV., Appendix V., post. 3. Where the wall exceeds thirty feet but does not exceed forty feet in height it shall be at its base of the thickness following: If the wall does not exceed thirty-five feet in length it shall be thirteen inches thick at its base; If the wall exceeds thirty-five feet but does not exceed forty-five feet in length it shall be seventeen and a half inches thick at its base; 57 & 58 Vict. Sch. I., Pt. II. rr. 4-6. If the wall exceeds forty-five feet in length it shall be twenty-one inches and a half thick at its base. Note. In the corresponding rule of the Act of 1855, the three divisions were walls not exceeding 30 feet in length, walls exceeding 30 feet and not exceeding 60 feet, and walls exceeding 60 feet. Otherwise the requirements of the rule remain unaltered. The present rule is illustrated in Diagram III., Pl. XIV., Appendix V., post. 4. Where the wall exceeds forty feet but does not exceed fifty feet in height it shall be at its base of the thickness following: If the wall does not exceed thirty feet in length it shall be seventeen and a half inches thick at its base; If the wall exceeds thirty feet but does not exceed fortyfive feet in length it shall be twenty-one inches and a half thick at its base; If the wall exceeds forty-five feet in length it shall be twenty-six inches thick at its base. Note. The classes into which walls within the corresponding rule of the Act of 1855 were divided, were walls not exceeding in length 40 feet, walls not exceeding in length 70 feet, and walls exceeding in length 70 feet; otherwise the rule has not been altered. This rule is illustrated in Diagram IV., Pl. XIV., Appendix V., post. 5. Where the wall exceeds fifty feet but does not exceed sixty feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall be twenty-one inches and a half thick at its base; If the wall exceeds forty-five feet in length it shall be twenty-six inches thick at its base. Note. The corresponding rule of the Act of 1855 contained three divisions instead of the two in the present rule, viz. :-Walls not exceeding 35 feet in length, which had to be 17 inches at their base, walls exceeding 35 feet in length but not exceeding 50 feet, which were required to be 211 inches at the base, and walls exceeding 50 feet in length, the bases of which were required to be 26 inches thick. An illustration of the present rule will be found in Diagram V., Pl. XV., Appendix V., post. 6. Where the wall exceeds sixty feet but does not exceed seventy feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall Note. The corresponding rule of the Act of 1855 contained three divisions, viz. :-Walls not exceeding 30 feet in length, the bases of which were required to be 171⁄2 inches thick, walls exceeding 30 feet and not ex ceeding 45 feet in length, of which the bases were required to be 21 inches, and walls exceeding 45 feet in length, the bases of which were to be 26 inches in thickness. For the provision respecting the distribution of the thickness of walls in piers, see Rule 3 of the Miscellaneous Rules, post. For an illustration of the present rule, see Diagram VI., Pl. XV., Appendix V, post. 7. Where the wall exceeds seventy feet but does not exceed eighty feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall Note. The three divisions into which the corresponding rule of the Act of 1855 was divided were walls not exceeding 45 feet in length, the bases of which were required as in the present rule to be 21 inches thick. Walls exceeding 45 feet in length and not exceeding 60 feet with bases 26 inches in thickness; and walls exceeding in length 60 feet, of which the bases were to be 30 inches thick. The provisions respecting the distribution of the thickness of walls in piers are contained in Rule 3 of the Miscellaneous Rules, post. An illustration of the present rule will be found in Diagram VII., Pl. XV., Appendix V., post. 8. Where the wall exceeds eighty feet but does not exceed ninety feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall be twenty-six inches thick at its base; If the wall exceeds forty-five feet in length it shall be increased in thickness from the base up to within sixteen feet from the top of the wall by four inches and a half (subject to the provision in this Schedule respecting distribution in piers). Note. The corresponding rule of the Act of 1855 was divided into walls the length of which did not exceed 60 feet with bases 26 inches thick; walls exceeding 60 feet and not exceeding 70 feet in length, of which the bases were 30 inches in thickness; and walls exceeding 70 feet in length, of which the bases were required to be 34 inches thick. The distribution of the thickness of walls in piers is provided for by Rule 3 of the Miscellaneous Rules, post. The present rule is illustrated in Diagram VIII., Pl. XV., Appendix V., post. 9. Where the wall exceeds ninety feet but does not exceed one hundred feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall be twenty-six inches thick at its base; If the wall exceeds forty-five feet in length it shall be increased in thickness from the base up to within sixteen feet from the top of the wall by four inches and a half (subject to the provision in this Schedule respecting distribution in piers). 57 & 58 Vict. Sch. I., Pt. II. rr. 7-9. 57 & 58 Vict. Sch. I., Pt. II. rr. 10-12. Condition in exceeding a certain height. Note.-Walls of the height specified in this rule were divided in the corresponding rule of the Act of 1855 into those which did not exceed 55 feet in length, the bases of which were required to be 26 inches thick; walls exceeding that length but not exceeding 70 feet in length, of which the bases had to be 30 inches thick; and walls exceeding 70 feet in length, the bases of which were required to be 34 inches in thickness. See Rule 3 of the Miscellaneous Rules, post, for the provisions as to the distribution of the thickness of walls in piers. In Diagram IX., Pl. XVI., Appendix V., post, will be found an illustration of the present rule. 10. Where the wall exceeds one hundred feet but does not exceed one hundred and twenty feet in height it shall be at its base of the thickness following: If the wall does not exceed forty-five feet in length it shall be thirty-one inches thick at its base; If the wall exceeds forty-five feet in length it shall be increased in thickness from the base up to within sixteen feet from the top of the wall by four inches and a half (subject to the provision in this Schedule respecting distribution in piers). Note. Under the Act of 1855 no provision was made for walls exceeding 100 feet in height, and this present rule is therefore new. The distribution of the thickness of walls in piers is provided for by Rule 3 of the Miscellaneous Rules, post. The present rule is illustrated in Diagram X., Pl. XVI., Appendix V., post. 11. The thickness of the wall at the top and for sixteen feet below the top shall be thirteen inches and a half and the intermediate parts of the wall between the base and sixteen feet below the top shall not be of less thickness than would be the case if the wall were to be built solid throughout the space between straight lines drawn on each side of the wall and joining the thickness at the base to the thickness at sixteen feet below the top : Nevertheless in walls not exceeding thirty feet in height the walls of the topmost storey may be nine inches thick provided the height of that storey does not exceed ten feet. Note.--The present rule is the same as the corresponding rule in the Act of 1855, except that the words printed in italics are new; and that in the case of walls not exceeding 30 feet in height the walls of the topmost storey, which might previously have been 8 inches thick, are now to be 9 inches thick, and that provided the height of the topmost storey does not exceed 10 feet. 12. If in any storey of a building of the warehouse class respect of storeys the thickness of the wall as determined by the provisions of this Schedule is less than one fourteenth part of the height of such storey the thickness of the wall shall be increased to one fourteenth part of the height of the storey and the thickness of each external and party wall below that storey shall be increased to a like extent but any such additional thickness may be confined to piers properly distributed of which the collective widths amount to one fourth part of the length of the wall. |
