A side wall 101 of an architectural structure 100 is fitted with a fixing member 130 at a level higher than the ground 500. The fixing member 130 is fitted with fixture studs 132. A mast 200 is erected on the fixing member 130 with its lower end secured to the fixture studs 132. A climbing work platform 210 that travels up and down the mast 200 is fixed to the mast 200. A worker performs maintenance operations on the climbing work platform 210. ## Claims ### Claim 1 A high-rise architectural structure that accommodates temporary attachment of a mast structure above ground level at positions suitable to facilitate maintenance of the high-rise architectural structure, the high-rise architectural structure comprising finished sidewalls that separate a building interior from a building exterior, at least one of said finished side walls extending vertically from a lower end at ground level to an upper end, the architectural structure comprising: at least one fixing member that extends outward from the at least one finished side wall of the architectural structure at a level at least two meters above the lower end of the side wall of the architectural structure, the fixing member having an upper surface and a lower surface;

and further comprising a plurality of connector pegs provided on the at least one finished side wall of the high-rise architectural structure, each of the connector pegs being permanently secured to the at least one finished side wall of the high-rise architectural structure, said peg including structure to facilitate temporary connection to the mast structure, the connector pegs each being vertically aligned with the fixture stud so as to facilitate attachment with the mast such that the lower end of the mast is attached to the fixture stud and the mast is connected to said connector pegs along its length such that the mast is supported stably by the fixture studs and the connector pegs. ### Claim 2 (depends on 1) The architectural structure according to claim 1, wherein the fixture studs are secured to the at least one fixing member. ### Claim 3 (depends on 1) The architectural structure according to claim 1, wherein the at least one fixing member has a flat shape that is rectangular when viewed from above. ### Claim 4 (depends on 1) The architectural structure according to claim 1, wherein the number of the at least one fixing members is two or more. ### Claim 5 (depends on 1) The architectural structure according to claim 1, wherein a single fixing member is configured to be fitted with the fixture studs to connect two or more masts to the fitting member. ### Claim 6 (depends on 1) The architectural structure according to claim 1, wherein a proximal end of each connector peg is integrally embedded in the side wall. ### Claim 7 (depends on 1) The architectural structure according to claim 1, wherein an anchor is provided, on the proximal end of the connector pegs to secure the connector pegs to the side wall. ### Claim 8 (depends on 1) The architectural structure according to claim 1, wherein recessed openings are provided in the side wall and the connector pegs are provided in recessed openings in the side wall; and wherein a removable opening cover is provided to cover the recessed openings so that that connector pegs are completely enclosed by the recessed openings and cover. ### Claim 9 A high-rise architectural structure that accommodates temporary attachment of a mast structure above ground level at positions suitable to facilitate maintenance of the high-rise architectural structure, the high-rise architectural structure comprising at least one finished side wall that separates a building interior from a building exterior and extends vertically from a lower end at ground level to an upper end, the architectural structure comprising: at least one pedestal member for supporting at least one chassis at a level at least two meters above the lower end of the finished side wall of the architectural structure, the chassis having at one fixture stud that permits connection to a lower end of the mast structure, and the chassis further comprising a base to which the fixture stud can be attached so that the lower end of the mast structure mast is positioned at least two meters above ground level, further comprising a plurality of connector pegs provided on the at least one finished side wall of the high-rise architectural structure, each of the connector pegs being permanently secured to the at least on finished side wall of the high-rise architectural structure, said peg including structure to facilitate temporary connection to the mast structure, the connector pegs being aligned so as to facilitate attachment with a mast such that the mast is connected to connector pegs along its length; and the base being configured to support the mast, the at least one pedestal member being configured to support the chassis thereon at positions to provide maintenance of the architectural structure. ### Claim 10 A maintenance method for a high-rise architectural structure that includes one or more fixing members extending outward from a finished side wall of the architectural structure at a level at least two meters above the lower end of the side wall of the architectural structure and a plurality of connector pegs provided on the finished side wall of the high-rise architectural structure, each of the connector pegs being permanently secured to the finished side wall of the high-rise architectural structure where each fixing member has an upper surface and a lower surface and structure is provided on the upper surface of the at least one fixing member to permit receipt of a plurality of fixture studs adapted for attachment to a lower end of the mast structure such that the mast structure is positioned above ground level, the at least one fixing member being configured to support fixture studs required to accommodate temporary attachment of a mast structure above ground level at positions suitable to facilitate maintenance of the high-rise architectural structure the connector pegs including structure to facilitate temporary connection to the mast structure, the connector pegs being aligned so as to facilitate attachment with a mast such that the mast is connected to connector pegs along its length; the maintenance method comprising the steps of: attaching the fixture stud to the at least one fixing member at a position where the mast structure is to be erected; setting the at least one mast along the finished side wall of the architectural structure by connecting the lower end of the at least one mast to the attached fixture stud; attaching the connector pegs to the mast such that the mast is connected to connector pegs along its length; attaching a platform to the erected at least one mast, the platform being capable of moving up and down the at least one mast to which it is attached; and moving up and down the platform along the at least one mast while a worker on the platform is performing maintenance of the architectural structure. ### Claim 11 A maintenance method for a high-rise architectural structure that includes at least one finished side wall extending vertically from a lower end at ground level to an upper end and structure that accommodates temporary attachment of a mast structure above ground level at positions suitable to facilitate maintenance of the high-rise architectural structure the architectural structure including at least one pedestal member for supporting at least one chassis at a level at least two meters above the lower end of the finished side wall of the architectural structure and a plurality of connector pegs provided on the finished side wall of the high-rise architectural structure, each of the connector pegs being permanently secured to the finished side wall of the high-rise architectural structure the chassis having at one fixture stud that permits connection to a lower end of the mast structure, and the chassis further comprising a base to which the fixture stud can be attached so that the lower end of the mast structure mast is positioned at least two meters above ground level, the base being configured to support the at least one mast, the at least one pedestal member being configured to support the chassis thereon at positions to provide maintenance of the architectural structure, the connector pegs including structure to facilitate temporary connection to the mast structure, the connector pegs being aligned so as to facilitate attachment with a mast such that the mast is connected to connector pegs along its length;
