A set of structural elements (1, 7) intended to be assembled to form an elevated parking with at least one level, said structural elements (1, 7) comprising deck modules, referred to as supported modules, which are substantially rectangular and arranged to form, in an assembled position, at least a part of the deck of an elevated parking level, and posts arranged to support the supported modules in said assembled position, said set of structural elements (1, 7) being characterised by the fact that: - each supported module comprises, at each of its two longitudinally opposite ends, at least one housing open at one end and capable of receiving a head of a post, and bearing means capable of bearing on a respective post after fitting the housings onto the heads of the posts so that the supported module is supported in a stable manner by the posts, - each post has a flange arranged to support a lower surface of a supported module, which lower surface forms, in whole or in part, said bearing means; - each housing of a supported module has, at its bottom, either at least one male centring element or at least one female centring element, while each post has at its free end, respectively, either at least one female centring element or at least one male centring element, the or each male centring element being arranged to be received in a respective female centring element (4f, 4g); and - the heads of the posts and the housings are dimensioned such that, after fitting the housings onto the posts, a first clearance greater than a clearance present between the other parts of the housing and the head of the post is present between the or each male centring element and the respective female centring element (4f, 4g), the first clearance being defined to allow the transmission of forces between the supported module and the post via the male centring element(s) and the female centring element(s) (4f, 4g). - each supported module comprises, at each of its two longitudinally opposite ends, at least one housing open at one end and capable of receiving a head of a post, and bearing means capable of bearing on a respective post after fitting the housings onto the heads of the posts so that the supported module is supported in a stable manner by the posts, - each post has a flange arranged to support a lower surface of a supported module, which lower surface forms, in whole or in part, said bearing means; - each housing of a supported module has, at its bottom, either at least one male centring element or at least one female centring element, while each post has at its free end, respectively, either at least one female centring element or at least one male centring element, the or each male centring element being arranged to be received in a respective female centring element (4f, 4g); and - the heads of the posts and the housings are dimensioned such that, after fitting the housings onto the posts, a first clearance greater than a clearance present between the other parts of the housing and the head of the post is present between the or each male centring element and the respective female centring element (4f, 4g), the first clearance being defined to allow the transmission of forces between the supported module and the post via the male centring element(s) and the female centring element(s) (4f, 4g).
