RU40641U1 - CONSTRUCTION OF QUICKLY CONSTRUCTED Dismountable FRAMES OF THE "INFINITY" SHELLS - Google Patents

Abstract

Utility model The construction of INFINITY prefabricated collapsible shell frames refers to the field of construction, namely, the enclosing structures of exhibition stands, pavilions, offices and residential premises. The technical result is the creation of the design of prefabricated collapsible frames of building shells of complex configuration (variable curvature). The design of the shell frames "INFINITY" is a combination of load-bearing elements and connecting nodes. The supporting frame elements (unified modules) are made in the form of spatial isosceles triangles, the hypotenuses of which are the same arched ribs, and the legs are either straight or arched depending on the shape of the created module. To form a shell framework, adjacent modules are interconnected by elements of the same type (hypotenuses or legs). The shell is grown either by connecting adjacent elements of neighboring modules, or by common elements in neighboring modules. Moreover, the legs and the planes formed by the vertices of the spatial triangle are always mutually perpendicular. To pair adjacent modules by hypotenuses, the connecting nodes suggest the possibility of creating the necessary angle of inclination of the rib plane relative to the plane of the module (the plane formed by the vertices of the spatial triangle). Fundamental is the minimum set of standard sizes of the element base of the unified construction "INFINITY" - one type of curved ribs-hypotenuses and two types of ribs-legs. The utility model was manufactured and presented as an exhibition stand at the Baltic Construction Week in 2003 in St. Petersburg, Russia. The design of "INFINITY" is convenient and simple for installation, operation, transportation and storage, allows you to implement complex design developments at the modern technical level.

Description

The inventive utility model The design of prefabricated collapsible shell frames "INFINITY" refers to the field of construction, namely, the enclosing structures of exhibition stands, pavilions, offices and residential premises.

Known Design of a prefabricated multifaceted building shell of flat bearing panels with connecting inserts, patent N 2116409, E 04 G 7/24, RU, 1998.

The advantage of a technical solution is the creation of a frameless shell of the dome of the exhibition hall.

However, the design allows you to build only dome shells, the constituent elements of which are flat.

Known Modular frame system consisting of load-bearing elements (struts, crossbars, struts and other details) and connecting nodes of the frame, patent N 2184823, E 04 G 7/24, US, 1998

The advantage of the design is the ability to build a spatial shell frame.

However, the framework formed in this case also consists of flat elements, with the help of which it is impossible to erect convex-concave shells of complex configuration.

The purpose of the proposed technical solution is to create a design of prefabricated collapsible frames of convex-concave shells of complex configuration (variable curvature) from unified spatial modules.

The goal is achieved as follows. The supporting frame elements (unified modules of the "INFINITY" design) are made in the form of spatial isosceles right-angled triangles, the hypotenuses of which are the same type of arched ribs, and the legs are made either rectilinear or arched depending on the shape of the created module. At the same time, the modules are interconnected by elements of the same type (hypotenuses or legs), and the sides of the legs and the planes formed by the vertices of the spatial triangle are mutually perpendicular. The drawings show:

Fig. 8 is a diagram of a shell frame extension, where

M1-M4 - modules.

The essence of the solution is as follows. To form a shell framework, adjacent modules M1, M2, M3, M4 (Figs. 4-7) are interconnected by the same elements - hypotenuses Z1 (Fig. 1) or legs Z2 (Fig. 2), Z3 (Fig. 3). The shell extension (Fig. 8) is carried out either by connecting adjacent elements of neighboring modules, or by using common elements in neighboring modules and connecting nodes. Moreover, the connecting nodes U3 are designed so that the legs and the planes formed by the vertices of the spatial triangle are always mutually perpendicular. To pair adjacent modules by hypotenuse, the connecting nodes U2L, U2R suggest the possibility of creating the necessary angle of inclination of the rib plane relative to the plane formed by the vertices of the spatial triangle (Figs. 5, 7).

The materials used for the manufacture of structural elements "INFINITY", as well as the method of connecting the elements and modules with each other, are not fundamental. As structural materials, wood, metals or composites can be used, and bolted or any other lock joints can be used to join elements and modules together.

Fundamental is the minimum set of standard sizes of the element base of the unified construction "INFINITY" - one type of curved hypotenuse ribs and two types of legs.

The proposed unified system "INFINITY" allows you to erect the frames of both the simplest shells (rotation and transfer), and more complex convex-concave shells of variable curvature.

The utility model was manufactured and presented as an exhibition stand at the Baltic Construction Week in 2003 in St. Petersburg, Russia. The design of "INFINITY" is convenient and simple for installation, operation, transportation and storage, allows you to implement complex design developments at the modern technical level.
