Изобретение относитс к строительству и может бьгть использовано в металлоконструкци х , например, типа сборно-разборного сооружени .The invention relates to the construction and can be used in metal structures, for example, of the prefabricated type.

Наиболее близким техническим решением по технической сущности и достигаемому результату вл етс сборно-разборный металлический каркас, включающий арки с верхними и нижними по сами, выполненными в виде подп тников (I.The closest technical solution to the technical essence and the achieved result is a collapsible metal frame, including arches with upper and lower ones themselves, made in the form of liners (I.

Недостатком известного решени вл етс то, что данный каркас не обеспечивает необходимой пространственной жесткости, а. также влечет к увеличению трудозатрат при монтаже, поскольку узел жесткости, представл ющий собой в данной конструкции либо подкосы, либо раст жки, устанавливаетс во врем монтажа при помощи винтовых или болтовых соединений.A disadvantage of the known solution is that this frame does not provide the necessary spatial rigidity, as well. also entails an increase in labor costs during installation, since a stiffness assembly, which in this construction is either struts or splices, is installed during installation by means of screw or bolted connections.

Цель изобретени - увеличение пространственной жесткости и снижение трудоемкости , монтажа.The purpose of the invention is to increase spatial rigidity and reduce labor intensity, installation.

Указанна цель достигаетс тем, что в сборно-разборном металлическом каркасе, включающем арки с верхними и нижними по сами, прогоны и узлы их креплени кThis goal is achieved by the fact that in a collapsible metal frame that includes arches with upper and lower ones themselves, the runs and their attachment points to

верхним по сам, выполненные в виде подп тников , каркас снабжен стержн ми, при-i .крепленными к боковой поверхности подп тников с двух сторон каждой арки по всей ее длине, причем концы восход щих стержней расположены с нахлестом и прикрепле ны к соседним подп тникам.the upper one, made in the form of podchnik, is provided with rods attached to the lateral surface of the pod ticks on both sides of each arch along its entire length, with the ends of the ascending rods arranged overlapping and attached to adjacent podniki .

На фиг. 1 схематично изображен каркас арочного типа, общий вид; на фиг. 2 - сечение А-А на фиг. I.FIG. 1 shows schematically an arch-type framework, general view; in fig. 2 is a section A-A in FIG. I.

Claims

10 contains arches 1 with upper catfish 2 and lower catfish 3, purlins 4 and their attachment points to the upper one along

2. Each fastening unit of the purlins 4 to the upper 2 arches I itself is made in the form of one common subassembly node 5, which are channel bars 6 fastened to the upper and lower 2 and 3 arches 1 on both sides; rectangular notch 7. In addition, the purlins 4 have extrudes 8 at their ends, which serve to fasten them in rectangular notches 7 of the channel 6 of the subtitle 5. To the lateral surfaces 9 of the ad hoc 5 on one and the other side of the arch 1 along its entire length rods 10 are attached, with the ends of the ascending rods 10 arranged with an overlap They are attached to adjacent baffles 5. The collapsible metal frame is mounted as follows. After the arches 1 are installed, the purlins 4 with their ends with the protrusions 8 are installed in the rectangular notches 7 of the channels 6 under the tnnkob 5 and fixed in them by bending the lateral shelves of the channels towards the ends of the purlins 4. Then the rods 10 are fixed allows you to eliminate the use of braces (diagonals) in the arch as well as in the junction of the girder to the arch, as the arch in this case has sufficient strength and rigidity to absorb the forces that cause buckling along the length of the arch and twisting the cross section arches. The proposed design of a collapsible metal frame allows to increase the strength characteristics of the arches and significantly reduce the labor costs for installation of the frame. Claims of the invention Collapsible metal frame, which includes arches with upper lower ones by themselves, girders and nodes of their attachment to upper ones by themselves. made in the form of cushions, characterized in that, in order to increase the spatial rigidity and reduce the complexity of the installation, the frame is provided with rods attached to the side surface of the cushions on both sides of each arch along its entire length, with the ends of the ascending rods overlapping and attached to neighboring dungeons.
