연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A method for making a covering is described. The covering includes a first layer made of a flexible material; a second and a third layers made of a preferably rigid material engaged on opposite sides to the first layer. The second and the third layers respectively have a plurality of V-shaped grooves defining respective adjacent rigid and corresponding structural portions. Each rigid structural portion can be oriented with respect to the adjacent rigid structural portion, by folding the first layer so as to model the covering according to three-dimensional configurations and/or a simple or double curvature. The method is preferably performed through a virtual designing of the shape desired to be obtained and a processing of the same for the obtainment of the grooves required to attain such shape.

1. A method for making a covering for complex structures comprising the steps of: providing a first layer made of a flexible material having a first and a second surface facing respectively opposite sides, by providing a net having a plurality of through openings;providing a second layer made of a substantially rigid material having a first surface and a second surface facing respectively opposite sides;fixing, said first surface of said second layer to said second surface of said first layer, by applying a glue or a similar adhesion substance onto said first surface of said second layer, and arranging said first layer onto said second layer so that the second surface of said first layer engages the glue placed on said first surface of said second layer;providing a third layer made of a substantially rigid material having a first surface and a second surface facing respectively opposite sides;fixing said first surface of said third layer to said first surface of said first layer, by applying a glue or a similar adhesion substance onto said first surface of said third layer, and by arranging said third layer onto said first layer on the opposite side with respect to said second layer so that the glue applied on the first surface of said third layer engages the first surface of said first layer;pressing said first layer, second layer, and third layer against each other;the arrangement of said first layer on said second layer and said third layer on said first layer causing embedding of said net of said first layer in said glue applied on said second and third layers, such that the glue applied on said second and third layers passes through said net of said first layer and fills the through openings of the latter so as to directly join said second layer to said third layer at said through openings;designing a three-dimensional shape of the covering and determining number and orientations of grooves on the second and on the third layers to allow the covering to take, in a mounting step, an established three-dimensional shape, the established three-dimensional shape being established by creating a structural virtual three-dimensional model or by importing a previously existing structural virtual three-dimensional model or by generating a structural virtual three-dimensional model from detection of a real three-dimensional shape, the determination of the number and the orientations of the grooves being performed through a step of processing the established virtual three-dimensional model, the determination step comprising execution and display of a preview of the structural configuration of the covering corresponding to the established final shape;storing the final three-dimensional model corresponding to the covering to be obtained;processing the shape of said final three-dimensional model for obtaining, in a plane, on the second and the third layers, the grooves required for obtaining the three-dimensional shape of the latter;determining a list of controls for controlling a numeric control machine, provided for obtaining, in a plane, on the second layer and the third layer of said covering, V-shaped grooves in order to obtain the determined three-dimensional shape;obtaining, by removing material in said second layer at least one groove, so as to define adjacent rigid structural portions, the making of each groove being performed by obtaining a cavity having a substantially V-shaped profile, the vertex of which is arranged close to or at said first layer;obtaining, by removing material, in said third layer at least one groove corresponding to the respective groove of said second layer, so as to define adjacent rigid structural portions, each corresponding to a respective rigid structural portion of said second layer, the obtaining of each groove being performed by forming a cavity having a substantially V-shaped profile, with a vertex arranged close to or at said first layer; andusing a resulting covering to cover complex surfaces or structures, as a furnishing element, as a self-supporting wall, or as a support structure. 2. The method according to claim 1, wherein the glue applied on the second layer and on the third layer is an expansion glue, a polyurethane or silicon glue or a similar glue, capable of trapping the net of said first layer between said second and third layers. 3. The method according to claim 1, further comprising a step of calibrating said covering comprising a reduction of the thickness of said second layer and/or said third layer. 4. The method according to claim 3, wherein said step of calibration comprises the following steps: placing said covering onto a work surface, the work surface being a suctioning one;locking said covering on said work surface, by suction;polishing said second layer for reducing the thickness of the same up to a predetermined value, the polishing of said second layer levelling off the same;polishing said third layer for reducing the thickness of the latter up to a predetermined value, corresponding to the thickness of said second layer, the polishing of said third layer levelling off the same. 5. The method according to claim 1, wherein both the virtual three-dimensional model and the preview of the structural configuration of the covering can be modified to vary the shape thereof. 6. The method according to claim 1, wherein the step of execution and display of the preview of the structural configuration of the covering is performed on the basis of the shape of the established virtual three-dimensional model and/or of the shape of the rigid structural portions to be made and/or of the number of the rigid structural portions to be made and/or of the arrangement of the rigid structural portions to be made and/or on the thickness of the second and third layers of the covering and/or of the material of the second and of the third layers and/or of the finishing to be performed. 7. The method according to claim 1, further comprising the step of analysing the established virtual three-dimensional model for estimating the stresses and/or the loads and/or the surface tensions generated on the corresponding covering, the analysis of the virtual three-dimensional model allowing the identification of areas or zones requiring respective support points and/or self-supporting areas or zones. 8. The method according to claim 1, wherein the established three-dimensional shape is established by generating a structural virtual three-dimensional model from detection of a real three-dimensional shape.
