Изобретение относитс к строительству и может быть использовано дл соединени стержней пространственных каркасов зданий и сооружений.The invention relates to the construction and can be used to connect the rods of the spatial frameworks of buildings and structures.

Известны болтовые соединени стержней каркасов пространственных покрытий, осуществл емые посредством узлового элемента , имеющего отверсти с резьбой, в каждом из которых размещена крепежна деталь .выполненна в виде болта или шпильки 1.Bolted connections of the cores of the frameworks of spatial coatings are known, which are carried out by means of a knot element having threaded holes, in each of which a fastener is placed. It is made in the form of a bolt or a stud 1.

Известно узловое соединение каркаса пространственного покрыти , включающее узловой элемент, трубчатые стержни с закладными детал ми в виде вкладыша, соединенные с узловым элементом с помощью крепежной детали в виде болта с двум гайками 2.A knotted joint of a spatial coating frame is known, including a knotted element, tubular rods with embedded parts in the form of an insert, connected to the knotted element by means of a fastener in the form of a bolt with two nuts 2.

Известные соединени не позвол ют осуществл ть регулировку длин стержней и их предварительное напр жение, а также требуют высокой точности изготовлени деталей .The known compounds do not allow the adjustment of the lengths of the rods and their prestressing, and also require high precision manufacturing of parts.

Наиболее близким к изобретению по технической сущности вл етс узловое соединение стержней пространственного каркаса, включающее УЗЛОВОЙ элемент с нарезнымиClosest to the invention to the technical essence is the nodal connection of the rods of the spatial frame, including the NODE element with threaded

отверсти ми и жестко закрепленные в торцах стержней нарезные наконечники (3).threaded tips (3) that are rigidly fixed at the ends of the rods.

Известное соединение не позвол ет осуществл ть регулировку длин стержней каркаса и их предварительного напр жени .The known compound does not allow adjustment of the lengths of the core bars and their prestressing.

Цель изобретени - обеспечение воз .можности предварительного напр жени и регулировки длин стержней в ос х узловых элементов каркаса.The purpose of the invention is to provide the possibility of prestressing and adjusting the lengths of the rods in the axes of the framework elements.

Указанна цель достигаетс тем, что в узловом соединении стержней пространственного каркаса, включающем узловой элемент с нарезными отверсти ми и жестко закрепленные в торцах стержней нарезные наконечники, узловой элемент снабжен шпильками, ввинченными в его нарезные отверсти , и ст жными муфтами, объедин ющими свободные концы шпилек и наконечники стержней.This goal is achieved by the fact that in a knotted connection of the core frame rods, including a knot element with threaded holes and threaded lugs rigidly fixed at the ends of the rods, the knot member is provided with studs screwed into its threaded holes and tightening couplings uniting the free ends of the studs and rod ends.

На чертеже изображено узловое соединение .The drawing shows a nodal connection.

Claims

The knotted connection comprises the nodal element 1 of the spatial frame with the studs 2 securely fixed in it, to which the rods 3 are attached with rigidly fixed tips 4 due to the displacement of the tensioning sleeve 5 with the clearance 6. The connection of the rod 3 to the nodule 1 is carried out by moving the sleeve coupling 5 from the stud 2 to the threaded part of the tip 4. The length of the rod in the axis of the knotted elements is controlled by the size of the gap 6 between the stud and the tip, and the pre-stress is reached by a depth of screwing the stud 2 into the threaded hole of the node. The use of the invention makes it possible to regulate the construction rise of large-span structures, increasing their strength and reliability. It can be used for any spatial frameworks of buildings and structures, and is particularly effective for frameworks of buildings erected in areas of high seismicity. Claims The nodal connection of the rods of the spatial frame, including the node with threaded holes and the threaded lugs rigidly fixed at the ends of the rods, is characterized in that, in order to allow the pre-stressing and adjustment of the lengths of the rods in the axes of the frame elements, the node has the studs screwed into its threaded holes, and the clamping sleeves connecting the free ends of the studs and the tips of the rods.
