Figure 1 shows a three-dimensional angular connection, General view; figure 2 is an example of the use of the same connecting element for profiles of another section; in Fig.3 - the same, using a connecting element of a modified design; figure 4 - ‘'view a in figure 1.

Объемное угловое соединение содержит устанавливаемый на торцы соединяемых профилей 1-3 тройник 4 и крепежные элементы 5. В профилях 1-3 выполнены продольные пазы 6-14 различной конфигурации. В профиле 1 дополнительно выполнен паз 15.Volumetric angular connection contains tee 4 and fasteners 5 mounted on the ends of the connected profiles 1-3. In profiles 1-3, longitudinal grooves 6-14 of various configurations are made. In profile 1, an additional groove 15 is made.

При выполнении в.профилях 1-3 открытых цилиндрических каналов 16 в качестве крепежных элементов 5 используют самонарезающие винты, в других случаях - обычные винты с метрической резьбой.When performing in profiles 1-3 open cylindrical channels 16, self-tapping screws are used as fasteners 5, in other cases, ordinary screws with a metric thread.

На наружных поверхностях граней тройника 4 выполнены Г-образные выступы 17-19, одна из полок каждого из которых расположена на одной из граней, а другая - на смежной с ней грани. В гранях тройника 4 выполнены отверстия 20 под крепежные элементы 5 и пазы 21, аналогичные пазам 15, под обшивки 22 каркаса (фиг.1 и 4).On the outer surfaces of the faces of the tee 4, L-shaped protrusions 17-19 are made, one of the shelves of each of which is located on one of the faces, and the other on the adjacent face. In the faces of the tee 4, holes 20 are made for the fasteners 5 and grooves 21, similar to the grooves 15, under the skin 22 of the frame (figures 1 and 4).

Тройник 4 может быть использован и для соединения профилей 23 и 24 другого сечения (фиг.2), включающего в себя пазы 25-28.Tee 4 can be used to connect profiles 23 and 24 of another section (figure 2), including grooves 25-28.

При выполнении тройника в виде полого, открытого с двух (а не с трех) сторон куба (фиг.З), в полости тройника 4 размещают закладную гайку 29, используемую для закрепления панели 30.When making a tee in the form of a hollow, open from two (but not three) sides of the cube (Fig. 3), a nut 29 is used in the cavity of the tee 4, which is used to secure the panel 30.

При сборке каркаса на грани тройника 4 устанавливают профили 1-3 их торцами и закрепляют последние с помощью крепежных элементов 5. При этом расположенные на каждой из граней тройника 4 полки Г-образных выступов 17-19 входят во взаимно перпендикулярные пазы профиля, установленного на данной грани, препятствуя его перемещению вдоль плоскости грани, что повышает жесткость соединения. Затем в пазы 15 и 21 соответственно профиля 1 и тройника 4 вводят обшивки 22.When assembling the frame on the edges of the tee 4, profiles 1-3 are installed with their ends and the latter are fixed using fasteners 5. Moreover, the flanges of the L-shaped protrusions 17-19 located on each of the faces of the tee 4 enter into mutually perpendicular grooves of the profile installed on this face, preventing its movement along the plane of the face, which increases the rigidity of the connection. Then, in the grooves 15 and 21, respectively, of profile 1 and tee 4, sheaths 22 are introduced.

При использовании профилей 23 и 24 (фиг.2) полка одного из выступов 17-19 входит в паз соответствующего профиля, а торец полки другого из тех же выступов взаимодействует с наружной поверхностью того же профиля.When using profiles 23 and 24 (figure 2), the shelf of one of the protrusions 17-19 enters the groove of the corresponding profile, and the end face of the shelf of the other of the same protrusions interacts with the outer surface of the same profile.

При использовании тройника с двумя открытыми сторонами (фиг.З) сначала закрепляют на тройнике профили 1, 23 и 24, затем закладывают в полость тройника гайку 29 и закрепляют панель 30.When using a tee with two open sides (Fig. 3), profiles 1, 23 and 24 are first fixed on the tee, then nut 29 is laid in the tee cavity and the panel 30 is fixed.

Разборку каркаса производят в обратном порядке.Dismantling the frame in the reverse order.

Изобретение позволяет повысить жесткость конструкции и степень ее унификации.The invention improves the rigidity of the structure and the degree of its unification.

Claims

The invention relates to magic engineering and can be used in various areas of the national household, in which prefabricated frame structures are used, in particular in support structures of electronic equipment. The purpose of the invention is to increase the stiffness of the structure and degree of unification by ensuring the use of the same connecting element of rigid stiffness to connect profiles of different configuration.
