Изобретение относитс к строительным конструкци м дл открытых крановых эстакад.The invention relates to building structures for open crane racks.

Известна колонна дл температурного шва пролетных строений мостов, содержаща массивную подопорную часть с расположением на ней двух опор, на которые опираютс пролетные строени мостов, при этом они бывают катковые илк подвижные тангенциальные 1 . The known column for the temperature weld of the bridge span structures, containing a massive supporting part with the location of two supports on it, on which the bridge bridge structures are supported, and they are roller-type mobile tangential 1.

Недостатком-, таких констрзтсцнй вл етс наличие больших сил трени , передаваемых опорами на колонну. Дл восприн ти таких сил требуютс развитые материалоемкие подопорные конструкции, что вл етс основным недостатком такой колонны. Поэтому она не может быть применена дл температурных швов крановых эстакад.The disadvantage of such constructions is the presence of large friction forces transmitted by the supports on the column. To absorb such forces, developed material-intensive supporting structures are required, which is the main disadvantage of such a column. Therefore, it cannot be used for temperature joints of crane racks.

Известна также колонна дл температурного шва крановой эстакады, содержаща подкрановую часть с траверсой 2.Also known is a column for a temperature weld of a crane trestle, comprising a crane part with a crosspiece 2.

Однако така конструкци материалоемка, используетс неэффективно, так как состоит из спаренных колонн, воспринимающих полную кра}1овую нагрузку.However, such a construction is material-intensive, it is used inefficiently, since it consists of paired columns that take up a full margin} the first load.

Цель изобретени - снижение материалоемкости колонн дл температурного шва.The purpose of the invention is to reduce the material consumption of the columns for the temperature weld.

Указанна цель достигаетс тем, что.колонна , содержаща подкрановую часть и траверсу, снабжена двум опорами, расположенными На траверсе, причем опоры соединены с траверсой шарнирно в продольном и жестко в поперечном направлени х. При этом колонна снабжена распоркой на уровне верха траверсы.This goal is achieved by the fact that the column containing the crane part and the traverse is equipped with two supports located on the traverse, the supports being connected to the traverse pivotally in the longitudinal and rigidly transverse directions. In this case, the column is equipped with a spacer at the top of the traverse.

Claims

The column for the temperature ish of the crane trestle (see Figs. 4, 5) contains the crane part 1, the yoke 2, is equipped with two supports 3 located on the yoke, with the supports connected to the yoke 2 pivotally in the longitudinal direction and rigidly in the transverse direction. The joining of the supports from the cross-beam column is carried out through the centering bar 4 by means of anchor plates 5, which provide a swivel joint in the longitudinal and rigid transverse directions (see Fig. 6, 7). When the column is hinged at the base to ensure geometric immutability, it is attached by a spacer 6 to an adjacent column of row 7 (see Fig. 2). The height of the supports is selected based on the size of the crane equipment and is taken such that the yoke 2 is located below the lower clearance, taking into account the normalized clearance in height. The crane beams 8 are located in the center of gravity of the cross-section of the crane part of the column, who is the most rational, the distance between them is based on the temperature elongation. The proposed design of the column for the temperature weld will eliminate the twin columns in the temperature welds, simplify the installation and reduce the material consumption of the weapon as a whole. Claim 1. Column for the temperature joint of a crane trestle, comprising a crane crane part, characterized in that, in order to reduce material consumption, it is equipped with two supports located on the traverse, the supports being connected to the crosshead in the longitudinal direction and rigidly in the transverse direction x 2. A column according to claim 1, characterized in that it is provided with a strut associated with an adjacent column row and installed at the top of the traverse.
