Abstract

A nodal connection of the same type of arch elements, including the ends of the connected elements with transverse fasteners from segments of round pipes through which the tie bolts are passed, a central connecting element with holes located along the circumference, characterized in that the same type of elements are made of paired C-shaped profiles, and the central connecting element is made in the form of a single sheet gusset placed between the ends of the C-shaped profiles, while the latter are provided with coaxial holes for additional tie bolts.

Description

The invention relates to the field of construction and is intended for the manufacture of arches assembled from similar elements that are used in the construction of lightweight arched buildings.

Known nodal connection of the same type of arch elements, including the ends of the connected elements with flanges, tightened together by bolts [book. Metal structures, T.2, Designer's guide under the general. ed. V.V. Kuznetsova, Moscow: Publishing House. DIA, 1998, pp. 228-238].

A disadvantage of the known joining of arch elements is the impossibility of joining the elements of the arch at different angles, and therefore changing their shape.

Also known is the nodal connection of the same type of arch elements, including the ends of the connected elements with concave gussets, a cylindrical insert, side pads with grooves for the ends of the concave gussets and a central coupling bolt [A.S. No. 676702. M.cl E04B 1/58. BI No. 28 from 07.30.91].

Nodal connection allows you to connect the elements of the arch at an arbitrary angle, however, it has a significant complexity of manufacturing and material consumption.

Closest to the invention is a nodal connection of the arch elements, including the ends of the elements to be connected with transverse fasteners from segments of round pipes, a central connecting element, including a central nodal insert with two lateral sheet overlays, in which there are coaxial holes located around the circumference, and coupling bolts [Patent RU No. 2273702 IPC E04B1 / 58. BI No. 10 of 04/10/2006].

The disadvantage of the nodal connection is the lack of strength of the nodal joints and the increased consumption of material for the manufacture of linings.

The invention is aimed at increasing the strength of the nodal joints and reducing material costs.

The result is achieved in that in the nodal connection of the same type of arch elements, including the ends of the connected elements with transverse fasteners from segments of round pipes through which the coupling bolts are passed, the central connecting element with coaxial holes located around the circumference, according to the invention, the same type of elements are made of paired C -shaped profiles, and the central connecting element is made in the form of a single sheet guss placed between the ends of the C-shaped profiles, while in the last See more aligned holes for coupling bolts.

Figure 1 shows an arch of six elements of the same type connected to the proposed nodal connections; figure 2 shows a General view of the connection node, node 1 in figure 1, conventionally on the right side shows the node in the assembly, and on the left side - the node at the time of alignment of the coaxial holes; figure 3 shows a cross section of the connection node, section 1-1 in figure 2.

The nodal connection includes the ends of the same type of elements 1 from C-shaped profiles with transverse fasteners 2 from pieces of round pipes, a sheet gusset 3 with holes 4 located around the circumference, and coupling bolts 5. Coaxial holes for additional coupling are provided in the walls of the C-shaped profiles bolts 6.

The assembly of the proposed connection node is implemented in the following sequence. The required angle of connection of the arch elements α _{i is} determined (FIG. 1) and the corresponding holes are found on the sheet gusset 3. In the cavity of the ends of the C-shaped profiles 1, a sheet gusset 3 is installed and the coaxial holes in the walls of the C-shaped profiles 1 and the fasteners 2 are aligned. Coupling bolts are installed in the combined holes 5. In this case, the coaxial holes in the gusset 3 and the walls of the C-shaped profiles 1 install additional coupling bolts 6.

The invention allows to increase the strength of the connection and reduce the consumption of material on the lining.
