Description

The invention relates to the field of construction, namely to frameworks of mesh shells of buildings and structures for various purposes.

The design of the mesh shell framework depends on a number of factors, the main ones being the purpose of the building or structure with its inherent architectural and technological conditions, the region of operation, the type of nodal connection, the cross-sectional profile of the core rods used and the type of roofing material.

Currently, two structural schemes of the mesh shell skeleton, which differ in the type of nodal connection, are widely used: the first scheme is on overlays, the second on star-shaped nodal parts.

In mesh shells, where for knotted parts pads are used in the form of die-cuts from a sphere or die-cuts from a flat cone (see RF patent 2183709, CL E 04 B 1/58, 06/20/2002), I-beams or T-beams are used as rods sections, while ensuring reliable connection of the plates with the shelves of the beams. The use of overlays and these types of cross-sectional profiles does not provide for the possibility of direct fastening of glass or double-glazed windows; the overhang protruding from the plane of the rod complicates the installation of any roofing panels except thin-sheet. The rods and nodes of such a shell must be further refined to give them a more aesthetic appearance.

Mesh shells are known, including a framework of trough-shaped rods (see USSR author's certificate 894110, class E 04 B 7/08, 12/30/81 and 657139 class E 04 B 1/58, 04/16/79) or box-shaped cross section (see USSR author's certificate 574509, class E 04 B 7/38, 16.01.78), which are adjacent to the nodal parts of a star-shaped shape with radially diverging rays. This type of mesh shells is closest to the proposed invention.

The disadvantages of mesh shells with star-shaped nodal details are: the use of only thin-sheet roofing material; the need to arrange a warm roof and suspended ceiling in heated rooms. Due to the applied method of attaching panels of roofing material, which, with some overlap, are fastened with screws directly through the panel to the frame rods, further maintenance and repair of the mesh casing is impeded, and leakproofness is achieved by lubricating joints with waterproofing mastics, which increases the complexity of manufacturing the casing and reduces its reliability from leakage. The used cross-sectional profiles of the carcass rods do not provide for the possibility of fastening rigid roofing panels, which greatly complicates the manufacture of translucent coatings or the installation of translucent openings.

The purpose of the invention is to simplify the manufacture of translucent mesh shells and increase their operational qualities.

-образного поперечного сечения, имеющие: внутреннюю полость 1, в которую входит луч звездообразной детали, полки 2 с пазами 3 для уплотнителя, вилку 4 для крепления к нему прижимной планки, полости 5 для отвода просочившейся воды и полку 6 для отвода конденсата с внутренней поверхности сетчатой оболочки.This goal is achieved by the fact that rods are used in the frame of the mesh shell

-shaped cross-section, having: an internal cavity 1, which includes a beam of a star-shaped part, a shelf 2 with grooves 3 for the seal, a fork 4 for attaching a pressure bar to it, a cavity 5 for draining leaked water and a shelf 6 for draining condensate from the inner surface reticular sheath.

-образного поперечного сечения. Полки стержней объединены в ниши, на которые через уплотнитель уложены стеклопакеты. При этом стеклопакеты имеют форму, повторяющую контур своих ячеек с учетом технологического зазора между торцом стеклопакета и вилкой

-образного стержня, необходимый для компенсации температурных деформаций и возможности его монтажа. Установленный в ячейку стеклопакет сверху закреплен через уплотнитель прижимной планкой. При этом прижимная планка притянута к вилке стержня через терморазрывную вставку саморезами, с шагом 200-400 мм. На прижимные планки сверху надеты декоративные крышки. В узлах ячеек каркаса полости стержней для отвода просочившейся воды объедены узловыми переходниками, которые входят в них на 10-30 мм и приклеены клеем, так что все полости сообщены между собой. По объединенным полостям вода стекает в наиболее низкие места оболочки и оттуда выводится наружу. Для придания узлам сетчатой оболочки более эстетичного вида снаружи и изнутри помещения на них надеты декоративные крышки.The mesh shell frame consists of cells, in the nodes of which are star-shaped parts with the required number of rays, and the perimeter is formed by rods

-shaped cross section. The shelves of the rods are combined into niches on which double-glazed windows are laid through the sealant. In this case, the double-glazed windows have a shape that repeats the contour of their cells, taking into account the technological gap between the end of the double-glazed window and the plug

-shaped rod, necessary to compensate for temperature deformations and the possibility of its installation. A double-glazed window installed in the cell is fixed on top through the seal with a clamping bar. In this case, the clamping plate is pulled to the rod fork through the thermal break insert with self-tapping screws, in increments of 200-400 mm. On the clamping strips on top are decorative covers. In the nodes of the cells of the carcass of the frame, the cavities of the rods for draining the leaked water are joined by nodal adapters, which are 10-30 mm in them and glued with glue, so that all the cavities are interconnected. Through the combined cavities, water flows to the lowest places of the shell and from there it is brought out. To give the nodes of the mesh shell a more aesthetic appearance on the outside and inside the room, decorative covers are put on them.

-образного поперечного сечения, узловых деталей звездообразной формы 9, прижимных планок 10, декоративных крышек 11, уплотнителей 12, терморазрывных вставок 13, узловых переходников 14, саморезов 15, стеклопакетов 16, болтовых соединений 17 и узловых крышек: верхних 18 и нижних 19.The mesh sheath 7 includes a frame of rods 8

-shaped cross-section, star-shaped knotted parts 9, clamping strips 10, decorative covers 11, gaskets 12, thermal break inserts 13, knot adapters 14, self-tapping screws 15, double-glazed windows 16, bolt joints 17 and knot covers: upper 18 and lower 19.

-образное поперечное сечение, в ячейках каркаса сетчатой оболочки образуются ниши, на которые укладываются и надежно там закрепляются стеклопакеты или любые другие жесткие кровельные панели. При этом не требуется точного совмещения плоскостей панели и полок стержней, образовывающих нишу, так как возникающие при этом несовпадения компенсируются упругими деформациями уплотнителя, что сильно упрощает изготовление сетчатой оболочки.Due to the fact that the core of the retina has

-shaped cross-section, niches are formed in the cells of the frame of the mesh shell on which double-glazed windows or any other rigid roofing panels are laid and securely fixed there. It does not require precise alignment of the planes of the panel and the shelves of the rods forming a niche, since the inconsistencies arising from this are compensated by the elastic deformation of the seal, which greatly simplifies the manufacture of the mesh shell.

In the case of local leakage, moisture along the connected cavities of the rods is removed to the outside, which increases the operational properties of the mesh shell.

-образное поперечное сечение заменяется на I-образное двутавровое путем добавления к

-образному нижних полок 20. Кроме того, при I-образном поперечном сечении достигается наилучшая передача продольного усилия через болтовые соединения в узлах сетчатой оболочки.With large spans, considerable longitudinal forces act in the rods of the retina, which can lead to a general loss of stability of these rods, as well as to local “clicking” of the shell. To prevent these negative phenomena

-shaped cross-section is replaced by an I-shaped I-beam by adding to

-shaped lower shelves 20. In addition, with an I-shaped cross-section, the best transmission of longitudinal force is achieved through bolted joints in the nodes of the mesh shell.

To increase the bearing capacity, as well as to impart geometric immutability to the retina as a whole, and in particular to the retina cells, star-shaped nodes are interconnected by cross-cable stretch marks. This prevents the deformation and destruction of double-glazed windows or other rigid roofing panels.

In order to increase the rigidity of the bolt connection, to avoid mutual shift between the beam of the star-shaped part and the shell rod, the rays of the star-shaped part have small narrowings 21 in the places of bolt attachment. When the bolts are finally tensioned, the walls of the shaft are deformed inward and fit snugly against the star-shaped part, while the wall takes on reducing the compliance of the compound.
