LT3695B - Folded roof - Google Patents

Abstract

Invention applies to construction and may be used for the construction of general-purpose buildings mostly of the agricultural type. The invention aims to increase engineering efficiency and achieve architectural expression. A folded plate roof consisting of two elements placed to mirror regarding roof's symmetrical axle that has a trapezium shape folds of walls folded in two opposite directions, steady-placed on supporting diaphragms, in the upper part joined by a horizontal longwise shearwall, making overall a stiff thin-walled spatial construction.

Description

The invention from the field of construction can be used for the construction of universal, mainly agricultural buildings - warehouses, barns, garages.

There is a known tile covering consisting of rigid curvilinear ribbed shell elements and a Lform span rod frame having frontal and side fencing. The shell elements are connected at the top of the vault. When installing the vaulting, adjacent shell elements are aligned with each other by welding metal inserts (USSR Aut. No. 1521840).

The disadvantage of the described construction is that it is complicated to manufacture and has low functional capabilities.

There is a known vault made of pleats (USSR aut. No. 1370200) for the external partition of civilian industrial buildings and structures. A gap vault consisting of folded folds interconnected by an outline and polygonal panels having four ridges, one of which forms the top edge of the strip, the second edge of the strip of broken lines, the third is in the radial plane and joins the tops of the top and bottom strips. Each panel is filled in the form of a single leaf gipar and the fourth edge of each gipar is positioned in the upper radial plane of the bar.

Disadvantages of this design:

- complex installation of the cover from individual elements with large common perimeter joints;

- complex temporary removal of elements in design position during installation;

- the cover profile in the upper area of the vault allows for snow accumulation.

There is a known pleated covering consisting of triangular elements arranged on a curvilinear surface of the strip which join together to form ridges. The curvilinear strips are made of two congruent parts mirrored to the axis of symmetry of the pavement. Each of them consists of pairs of congruent triangular elements, which are also mirrored in relation to the axis of the strip (USSR Aut. No. 1189963).

The present invention is similar in design and effect to the present invention and is therefore selected as a prototype. Disadvantages of this pleated cover:

- the large number of individual joints with their contours, making it practically impossible to join multiple joints at one point on the top of the pavement;

- disadvantages of the first two options - irrational use of the building due to the pavement profile - snow may accumulate on the pavement.

The object of the invention is to increase the engineering efficiency.

The essence of the invention is that the proposed pleated cover consists of two elements mirrored in relation to the longitudinal axis of the cover symmetry, the elements consisting of trapezoidal wall pleats bent in two opposite directions. These elements are rigidly mounted on support diaphragms and connected at the top by a horizontal longitudinal stiffness diaphragm and form an overall rigid thin-walled spatial structure.

The essence of pleated cover is explained in the drawings. Figure 1 Figure 2 is a general view of the cover. - Section A-A in Figure 1

The pleated cover consists of two elements 1, mirrored in relation to the axis 2 of the cover symmetry. The elements consist of trapezoidal wall pleats 3 folded in opposite directions in two places. The cover elements 1 are rigidly mounted on the supporting horizontal diaphragms 4, connected at the top by a horizontal longitudinal stiffness diaphragm 5.

Plasterboard elements are manufactured in a construction company or on a construction site. 15 mm thick layer of fibrobeton is sprayed on formwork laid in the horizontal plane, and the formwork walls are thickened in the upper area. For larger openings, the edges are also thickened (by placing panels on a formed 15 mm thick layer of fibrobeton, the shape and dimensions of which make the edge thickening zone). When the tensile strength of the fiber concrete reaches the required value, the structural member (or its section) is removed by attaching the traverse and mounted by a crane. The structure is based on a horizontal bar (foundation), and in the central part of the building span - a temporary tower scaffold. Joints between element sections are soldered. The elements are connected in a known manner at the top by a monolithic reinforced concrete strip - a stiffening diaphragm. The temporary supports are then dismantled.

The plank cover is a rigid system and does not require an internal frame. The spatial design of the pleated cover ensures spontaneous water drainage without the possibility of snow accumulation. The plasterboard is thin-walled and lightweight, made of hydrophobic material (fibro-concrete), so it does not require additional roofing.

The production and assembly of the proposed plank cover reduces labor costs. Plastered pavement - ecologically clean, no construction wood, chipping, roofing materials, significantly reduced metal yield.

The shape of the structure gives the building an architectural 10 expression.
