Изобретение относитс к области строительства и может быть использовано в качестве несущи.х конструкций покрытий промышленных зданий и сооружений.The invention relates to the field of construction and can be used as carrier structures for coatings of industrial buildings and structures.

Известна металлическа ферма с по сами таврового сечени и решеткой из уголков, в полках которых выполнены прорези 1.The metal truss is known with a T-section themselves and a grid of corners, in the shelves of which cuts 1 are made.

Данное решение сложно, так как требует высокой точности изготовлени прорезей, использовани проката разного профил .This solution is difficult because it requires high precision in the manufacture of slots and the use of rolled different profiles.

Наиболее близким техническим решением вл етс металлическа ферма, включаюш ,а по са и соединенные с ними элементы peujeTKH таврового сечени , в которой каждый элемент решетки на концах выполнен с продольными прорез ми в полке, в которые заведены и жестко соединены стенки по сов фермы 2.The closest technical solution is a metal truss, including, and the peuje TKH tavra elements connected to them, in which each lattice element at the ends is made with longitudinal slots in the shelf, into which the walls of the truss 2 are rigidly connected.

Недостатком этой фермы вл етс сложность ее изготовлени и сборки из-за большого количества прорезей, необходимости завод,ки элементов двум прорез ми в полки по сов, образованных спаренными уголками. Ввиду того, что верхний и нижний по са фермы изготовл ют из уголков, образуюш,ихThe disadvantage of this truss is the complexity of its manufacture and assembly due to the large number of slots, the need to plant, the elements of the two slots in the shelves formed by the paired corners. In view of the fact that the upper and lower sa trusses are made of angles that form

тавровое сечение, то имеет место повышенный расход металла.T-section, then there is an increased consumption of metal.

Цель изобретени - снижение расхода мета.пла и трудоемкости изготовлени .The purpose of the invention is to reduce the consumption of meta.pla and the complexity of manufacturing.

Достигаетс это тем. что в металлической ферме, включающей по са и соединенные с ними элементы решетки таврового сечени , в которой каждый элемент решетки на концах выполнен с продольными прорез ми в полке, в которые заведены и жестко соединены стенки по сов фермы, продольные прорези в полке элемента решетки расположены с разных сторон его стенки.This is achieved by the fact. that in a metal truss including cus and the tavra section lattice elements connected to them, in which each lattice element at the ends is made with longitudinal slits in the shelf, into which the walls of the truss are inserted and rigidly connected, the longitudinal slits in the shelf of the lattice element are located from different sides of its wall.

На фиг. 1 изображен верхний узел предлагаемой фермы; на фиг. 2 - нижний узел; на фиг. 3 - элемент решетки.FIG. 1 shows the top node of the proposed farm; in fig. 2 - lower node; in fig. 3 - lattice element.

Металлическа ферма включает верхний 1 и нижний 2 по са таврового сечени , стенки которых соединены с элементами 3 решетки .The metal truss includes the upper 1 and lower 2 of the cross section, the walls of which are connected to the grid elements 3.

Claims

Each lattice element has a T-section and at the ends is made with longitudinal slits 4 located in a shelf flush with the wall and on all sides from it. The lattice elements are made with slots in the walls of the upper and lower ground. In this case, in the upper node, the walls of the lattice elements are located on both sides of the wall of the caus, and in the lower node, the walls of the diagonals are located on one side of the wall of the lower belt, and the wall of the stand - on the other. Such an embodiment of the truss makes it possible to reduce the consumption of metal for its manufacture by reducing the weight of pigs and significantly reduce the cost of manufacturing the structure. Claims of Invention A metal truss, inclusive of the T-section lattice elements connected with them, in which each lattice element at the ends is made with longitudinal slots in the shelf, into which the walls of the truss are inserted and rigidly connected, characterized in that in order to reduce the consumption of metal and the complexity of manufacturing, the longitudinal slots in the shelf of the lattice element are located on different sides of its wall.
