Description

Изобретение относитс к области строительства воздушных линий электроперецачи.The invention relates to the field of construction of electroprecice air lines.

Известно крепление перекрьтаюшихс элементов дерев нных конструкций с использованием боковьк столиков из металла или дерева, при креп енньгх по боковым сторонам одного из элементов .It is known to mount overlapping elements of wooden structures using the side tables of metal or wood, with the fastening on the lateral sides of one of the elements.

Известно крепление двух перекрещивающихс дерев нных элементов в анкерно-углов дерев нных опорах подкосного типа 21 , It is known to mount two intersecting wooden elements in the anchor-angles of wooden supports of the strut type 21,

Наиболее близким техническим решением вл етс узел креплени траверсы к стойке дерев нной опоры анкерного типа, содержащий опорный кронштейн с горизонтальной полкой и болты дл креплени траверсы и кронштейна .The closest technical solution is the fixing unit of the crosshead to the rack of the anchor-type wooden support, which contains a support bracket with a horizontal shelf and bolts for fixing the crossbar and the bracket.

Общим недостатком известных устройст вл етс мала прочность и жесткость узла креплени траверсы.A common drawback of the known devices is the low strength and rigidity of the fixing unit of the crosshead.

Цель изобретени - повышение прочности жесткости узла креплени траверсы.The purpose of the invention is to increase the strength of the rigidity of the fixing unit of the cross member.

Это достигаетс тем, что узел креплени траверсы к стойке дерев нной опоры ЛЕП, включающий прикрепленный к стойке металлический кронштейн с горизонтальной This is achieved by the fact that the fixing unit of the traverse to the rack of the wooden support of the LEP, including a metal bracket attached to the rack with a horizontal

полкой, на которую оперта дерев нна траверса , кронштейн вьтолнен составным из Ьимметрично расположенных по обе стороны стойки металлических элементов, скрепленных между собой и со стойкой ст жными болтами, причем каждый из элементов вьтолнен зеркально относительно другого и снабжен наклонной полкой, образующей с его горизонтальной полкой тупой угол, а траверса скреплена с кронштейном ст жными болтами, расположенными перпендикул рно плоскости его наклонных полоthe shelf on which the traverse wood is supported, the bracket is made up of a composite of metal elements symmetrically located on both sides of the rack, fastened together and with resistant bolts, each of which is mirrored relative to the other and provided with an inclined shelf forming with its horizontal shelf obtuse angle, and the traverse is fastened to the bracket with clamping bolts perpendicular to the plane of its inclined polo

На фиг. 1 и 2 - изображен узел креплени в разрезе и в плане.FIG. Figures 1 and 2 depict a mount in section and in plan.

Claims

; The fixing unit of the traverse to the rack 1 of the wooden support of the power line includes a metal bracket 2 attached to the rack with a horizontal shelf 3 on which the wooden traverse 4 is supported, the bracket is made of symmetrically located on both sides of the rack of metal elements 5, fastened by itself and with the rack 1 with fixed bolts 6. Moreover, each of the elements is made mirror-like with respect to the other and is equipped with an inclined shelf 7, which forms an obtuse angle with its horizontal buttock 3, and the traverse is fastened with a bracket E bolts 8 disposed perpendi molecules to the plane of its inclined flanges. The implementation of a two-part bracket by placing them on opposite sides of the rack increases the base of the bearing, which increases the rigidity of the structure and the bearing capacity of the support. The presence of inclined shelves in combination with horizontal shelves and fastening the crossbar with bolts reduces the forces in the horizontal plane from the wires fixed on it and limits the possibility of the bolts bending to fix the crossbars and thereby limits the occurrence of deformations and see them underneath, which will allow using unified wooden parts for the crossbars . The implementation of the fastening elements of sheet material will allow the construction of a punching metope using simple punching machines. The execution of this node expands the use of wooden anchor supports of the type of strut-type execution. Claims An attachment unit for a cross member to a rack of a wooden power transmission pylon includes a metal bracket attached to the rack with a horizontal shelf on which a wooden traverse operk, characterized in that, in order to increase the strength and rigidity of the assembly, the bracket is combined with symmetrically arranged along both sides of the rack of metal elements fastened together and with resistant bolts, each of the elements being made mirror with respect to the other and provided with an inclined shelf forming with its horizontal shelf has an obtuse angle, and the traverse is fastened to the bracket with fixed bolts perpendicular to the plane of its inclined shelves.
