[Summary] A shell element that can be formed simply and in a short time, a shell structure using the shell element, and a structure forming set that can form the shell element simply and in a short time are provided. Resin material is foamed on the inside of thin film, a foamed material portion with bubbles being mixed is in the state of being sandwiched by the thin film and a solid layer, and tensional stress is applied to the thin film and the solid layer and compressive stress is applied to the foamed material portion, thus the shell element is difficult to be cracked or split, and the shell structure is formed by the shell element. And, the shell structure forming set forms the shell structure easily.

A transverse span for an airform membrane is disclosed that can include a material having a perimeter defined at least in part by a longitudinal edge having opposite ends that terminate at a base edge further defining the perimeter. The longitudinal edge can be configured to couple to a longitudinal edge of an adjacent transverse span of the airform membrane. The base edge can at least partially define a base perimeter of the airform membrane for coupling with a base support structure. The transverse span can also include a load compensated region with a length dimension and/or a width dimension reduced from an intended final dimension to compensate for stretch of the material when the airform membrane is inflated. In addition, the transverse span can include a flare region between the load compensated region and the base edge. The flare region can transition in the length dimension and/or the width dimension between the load compensated region and the base edge.

The present disclosure relates to deployable structures and methods of use thereof. In particular, deployable structures with non-cylindrical or irregular shapes and methods of use thereof are disclosed. Non-cylindrical combustion elements can be used to rigidize such non-cylindrical or irregular shapes. The use of gaseous oxidizers along with deployable structures is also disclosed.

A shell element that can be formed simply and in a short time, a shell structure using the shell element, and a structure forming set that can form the shell element simply and in a short time are provided.

Resin material is foamed on the inside of thin film, a foamed material portion with bubbles being mixed is in the state of being sandwiched by the thin film and a solid layer, and tensional stress is applied to the thin film and the solid layer and compressive stress is applied to the foamed material portion, thus the shell element is difficult to be cracked or split, and the shell structure is formed by the shell element. And, the shell structure forming set forms the shell structure easily.

The object of the invention is an 1-profile preform which comprises an outer wall (1) of the first flange and two inner walls (2) of the first flange arranged with respect to the outer wall (1) of the first flange, a first web wall (3) and a second web wall (4) being arranged in a plane parallel with respect to the first web wall (3), an outer wall (5) of the second flange, and two inner walls (6) of the second flange arranged with respect to the outer wall (5) of the second flange, wherein the corresponding walls (1, 2, 3, 4, 5, 6) are arranged with respect to each other while retaining a gap forming a closed empty inner space of an 1-profile preform, and wherein a valve element (7) is arranged on at least one wall (1, 2, 3, 4, 5, 6). The object of the invention is also an 1-profile manufacturing method with the use of an 1-profile preform.

A method and system for constructing a monolithic structure with a moldable mixture including one or more rigid forms connected to form an inner rigid wall, an inner inflatable air form, wherein the inner inflatable air form extends from the inner rigid wall, one or more rigid forms connected together to form an outer rigid wall, and an outer inflatable air form, wherein the outer inflatable wall extends from the outer rigid wall.

Described is an assembly for erecting a reinforced structure of a hardening building material using a pneumoform. The assembly includes an anchor bar having a first portion secured to a foundation and a second portion; a clamp bar configured to be aligned with the second portion of the anchor bar; a fixation element configured to extend through the clamp bar and the second portion of the anchor bar; and a pneumoform having an outer perimeter incorporating a keder. The outer perimeter of the pneumoform is positionable within a space between the second portion of the anchor bar and the clamp bar such that upon locking the clamp bar to the anchor bar with the fixation element the keder is captured by the clamp bar creating a first seal and forming a fluid-tight internal volume configured to be inflated. Related assemblies and methods are described.

The present invention relates to a pneumatic structure (10) comprising an inextensible body (12) defining at least a network of internal cavities (14), each cavity having a closed contour in at least one section of the cavity Each cavity being suitable for being pressurized so as to change the inextensible body from a rest configuration to at least one pressurized configuration, Inextensible body having, in each pressurized configuration, a macroscopic metric different from its macroscopic metric in the rest configuration, Each cavity being formed of at least two substantially rectilinear channels, each channel being fluidly connected to at least one of the other channels, the two said channels forming a heading change angle, Each cavity comprising at least one non-zero heading change angle, in particular at least three non-zero heading change angles.

The invention relates to a form element (1), an arrangement comprising such a form element (1) and a method for forming at least part of a formwork for a concrete part using this form element (1), wherein the form element (1) is flexibly three-dimensionally deformable in its first state, and wherein the form element (1) is stiffened and solidified in its second state, in particular in a deformed position of the form element (1), wherein the form element (1) comprises at least two flexible layers (2), which are arranged superimposed in a planar manner, and wherein the layers (2) are connected to each other, in particular reversibly, in the second state to solidify the form element (1).
