Each leg is equipped with attached to it a pair of axes, with which the hinge is connected the respective struts, each located in the bearing zones of the beams of the supporting and fixing element is designed as leaf area and attached to each shelf pair of connecting parts, mostly cylindrical, and the struts are made in the upper zone with an angular neckline, which has a supporting element made in the form attached to the edges of the cutout area, and on the shelves last supported connecting components orthogonal located to the beam. 4 C. p. F.-ly, 9 IP great migration is one of the main advantages allowing, in particular, to implement a large overlap.The invention relates to the implementation of large spans such that occur in structures with a large surface and in industrial halls, the combination of, on the one hand, beams, preferably of plate type on glue or made of composite materials, except in metal or concrete, with a large span, comprising parallel side panels with conventional transverse beams, and on the other hand, metal frame support.The invention relates to an improved system support and the suspension beams with a large span of plate type on glue or made of composite materials on the metal supporting pillars, and the system is designed so that there is conversion of a vertical reaction weight beams into force of the retaining arches in the corresponding rack, and is created in this way in the beam horizontal force arising in the longitudinal direction, which increases the possible migration mentioned beams.Known construction including support columns located in spans between beams, the pair of struts, each of which is attached the lower the>Theplaced on the upper ends of the struts and bearing areas of the reference beams and fasteners and attached to the upper end of the bar, holding the longitudinal beams placed between beams arranged in spans between columns.In Fig.1 shows the scheme of the construction of Fig.2 a front view of the upper part of the rack with two struts that supported the ends of the two beams; Fig.3 a top view of a fragment of the structure of Fig.4 a front view in Fig.2 and 3; Fig.5 section a-a in Fig.4; Fig.6 a section along b-B in Fig.4; Fig.7 a view of the upper end of the strut of Fig.4,5,6 mounting end of the beam with a large span of Fig.8 a top view of the end of the strut shown in Fig.7; Fig.9 a front view, each of the end uprights to compensate for the lateral pressure acting on the side beams with a large span on the rack.The structure consists of beams with large spans 1, 2, 3 plate type on glue or made of composite materials, except metal materials or concrete comprising parallel longitudinal side panels and metal support columns 4, 5, 6 H-shaped section. The construction includes a pair of struts 7, 8 for 4 hours and beams 1, 9, 10 for 5 hours and beams 1 and 2, 11, 12 de structures.Now identify, referring to Fig.2-9, the structure of the building to ensure translation of the vertical reaction of the weight of the beam in a force on the corresponding rack, and how to create a beam in the horizontal longitudinal force of the impact, which is the result of an increase in the maximum possible span of beams of this type.Referring first of all more particularly to the case of paired struts 9, 10 for 5 hours and beams 1 and 2, which are shown in Fig.2-8, it is clear that symmetric with respect to the longitudinal axis of symmetry XX of the rack 5, the structure consists of a pair of struts 9, 10, pivotally connected at their lower ends on the axles 11, 12, a fixed pin on the rack 5 so that there is no friction. In addition, these struts are provided on the upper end of the support parts 13, 14.On the other hand, the parts of the Shoe 15, 16 are fixed by gluing, balciunas or riveting on the bottom corners of the respective beams 1, 2, and these parts have contact details 17, 18 corresponding parts 13, 14. Even before a more detailed description of the uprights can be seen that for each of these racks vertical reaction Ryweight of the beam 1 or 2 is converted into the impact of Rpin the corresponding strut, which creates a beam 1 or 2 horizons beams.It is important to note that this concept of active efforts have compulsory passage point, namely the hinge axis 11, 12 to the efforts of Rpon the struts 9, 10 and the connecting parts 17, 18 for vertical reaction Ryalmost 30 tons for spans of 24 m, and the horizontal emphasis provides longitudinal loading in the beam M=Rne, where e is the distance of the PCT between the obligatory passage point of the horizontal force Pnand the neutral fiber of the beam 2.We now turn to a detailed description of how the can be mainly performed each of the struts 9, 10 in Fig.2, referring to Fig. 4-8. These braces should be designed to resist buckling; each of them is performed (Fig.6) longitudinal weld 19 two asymmetric profiles of the Y-shaped section 20, 21. These profiles have at their lower ends, sharpened asymmetrically (Fig.4), the holes 22, 23, which provides the rotation of the complex of the knee on the axis of the support 12, thespontaneous in the holes 24, 25, made in the shelves of the rack 5 H-shaped section.To allocate local loads on the surfaces of the struts, and the surfaces of the respective shelves of the rack, nlkah rack plate 28, 29.Previously in the description of Fig.2 it was evident that the beam 2 rests with its end on the upper end of the respective strut 10 and that the construction is designed in accordance with the invention so that efforts Ry, Rnand Rphad the obligatory point of passage, so that the calculation and control efforts would be as simple as possible and accurate.In Fig. 7 and 8 shows in a larger scale of a preferred form of the invention.In this case, the end of the beam 2 has a terminal element 16 in the form of area, each of the shelves of which is provided with a connecting piece in the form of a cylinder or half 18, which are supported on the corresponding element 14 of bearing area, welded to the upper end of the strut 10. Obviously, in this case, the vertical and horizontal forces Ryand Rnand the point of their application accurately determined and controlled from the moment when the beam 2 is placed (Fig.1) on the struts 9, 10 racks 5 and 6.Horizontal loading, the thus created in the beam 2, allows, as it was shown earlier to increase the maximum possible span mentioned beams. In addition, it is seen that in a timely manner automatically is s, such as saturated polyester fabric, pipes, fibers, etc. with the exception of metal and concrete.Obviously, possibly the hinge connection brace-supporting element, which support element is simply supported beam, would be hinged at the knee, but this solution, a priori, is an undeniable difficulties during installation and use. In addition, it can be understood that the end piece 16 has only one connecting the cylinder of large radius, supported by two regiments of area 14 of the strut, but this solution is the difficulty of mounting a single cylinder on oparam element and control of the distances to the points of support for both vertical and horizontal strain Ryand Rn< / BR>There is no doubt that the preferred solution described previously, has a clear advantage in that the obligatory passage point of these efforts is precisely defined by elements 18, area 16, is placed on the area 14, the strut 10. Because the beams 1 and 2 simply placed their end elements 15 and 16 on the struts 9, 10, 5 hour continued up and equipped in the upper part (Fig.2 and 3) two wind protect system beams 30, 31, which are attached in the center of the rack 5 shelves H-shaped section and is clamped in Boko is ut to be collected by the plates 32, 33 and serve as a support for equipment, such as climatisation, heaters, etc.The angle which should form the brace 10 with respect to the vertical axis of symmetry XX of the rack 5 is determined depending on the characteristic data of the constituent elements (beams, pillars, minimum height under the ceiling, and so on) are implemented by designs with large span.Mathematical theory requires that the center of gravity of the long span beams 2, the geometric center of the end area 16, which is equipped with the mentioned beam, and the geometric center of the swivel 12 on the rack 5 would be located on the same arc of a circle.In practice, the angle must be enclosed between 30 and 60aboutand preferably, because it is much easier from the point of view of practical, he should be 45about.In accordance with another characteristic of the invention extreme hours, for example 4, Fig. 1 and 9, for which the effect of horizontal loading Rnthat takes place in part 1 and which is converted into the impact of Rpon the rack 4, not balanced symmetrical reverse the effects of the other beams, as is, for example, in the case of the rack 5, and which should be is the continuation of the strut 7 to support its lower end on the ground, as is clearly seen in Fig.1. Thus, the construction is in perfect balance.The invention is an improved structure that provides support and suspension beams with a large span of plate type on glue or composite materials for metal support columns, with each column, at least one brace, hinged at its lower end on the rack, to which one end of a beam with a large span is supported by the stand; a connecting part located on the beam or on the upper end of the strut, and the supporting elements located on the upper end of the strut or beam, which are based on the connecting elements, moreover, the location of these connecting and supporting elements such that the weight of the beam produces a longitudinal compression force along the axis of the rack, which creates a longitudinal compression force on the beam.It is obvious that the present invention is not limited to implementation option, which has been described and shown, but encompasses all variants that can be represented by a specialist. 1.
