Abstract

FIELD: construction.

SUBSTANCE: method to assemble a sectionally broken arc includes connection of arc elements in units on bolts or with welding. Arc elements are made with cross section of two channels on planks. Some panels of the arc are assembled with external orientation of channel shelves, the other ones - with the internal one. The distance between walls of the adjacent panel channels is accepted as equal. Then the adjacent panels of the arc are overlapped with walls of channels above each other and in levelling holes by the contour of arc breaking angles are connected to each other. Afterwards, the arc assembly is completed with symmetrical or asymmetrical orientation of panels in semi-arcs.

EFFECT: simplified assembly.

Description

The invention relates to the construction and relates to a method of assembling an arch made of straight sections of profiles.

Known methods for assembling piece-broken arches from segments of rolling profiles, in which the ends of straight panels are welded to the nodal elements or fittings, and then they are connected in the nodes of the arches with bolts or welding (see AS No. 949117, bull. No. 29 from 08/07/92).

This method of assembling the arch is laborious in the manufacture and installation.

Closest to the invention is a method of assembling the connection of the ridge node of lattice structures, in which piecewise broken belts of trusses, frames are made of two C-shaped profiles or channels on the slats and bolted to their knot connection made of segments of two profiles (see patent RU 80691 U1, E04B 1/58, 02/20/2009, bull. No. 5).

In this solution, the assembly of nodes is carried out using additional nodal gussets and requires twice as many bolts, which leads to the complexity of manufacturing and assembling structures from piece-broken profiles.

The invention is aimed at simplifying the assembly of an arch from piecewise-broken straight panels with a section of belts composed of two C-shaped profiles or channels on the slats and connected to the arch nodes by bolts or welding.

The goal is achieved in that some arch panels are assembled with a cross section of two profiles with the outer orientation of their shelves, and adjacent arch panels are assembled with the internal orientation of their shelves, while the distance between the walls of the profiles of adjacent panels is taken equal; then adjacent panels of the arch overlap the walls of the profiles against each other and on straightening holes to outline the angles of the fracture of the arch connect them together, after which they complete the assembly of the arch with a symmetric or asymmetric orientation of the panels in the semi-arches.

The goal is also achieved by the fact that for symmetrical semi-arches the ridge panel is shortened and horizontal.

The method of assembling a piece-broken arch is illustrated by drawings, where Fig. 1 shows a diagram of a piece-broken arch assembled with a section of panels of two straight channels; figure 2 - one panel of the arch, assembled on slats with a cross-section with the outer orientation of the shelves of the profiles; figure 3 - other panels of the arch, assembled with a cross section with the internal orientation of their shelves; figure 4 - Assembly of the panels of the arches between themselves and the assembly of the ridge site for a symmetrical solution of the panels of the semi-arches.

A method of assembling a piece-broken arch includes assembling it (Fig. 1) from straight panels 1 or 2 with a cross section of two profiles 3 assembled on strips 4 (Figs. 1, 2, and 3). Panels 1 and 2 of the arches are connected at the nodes “A” of the arches (Fig. 4) by overlapping the ends of panels 1 and 2 on bolts or on welding. According to the method, one panel 1 of the arch is assembled with a cross section of two profiles 3 with the outer orientation of the cross section of their shelves 5 (Fig. 1, 2), and adjacent panels 2 of the arch are assembled with the internal orientation of their shelves 6 (Fig. 1, 3), the distance between the walls 7 of the channels 3 of the adjacent panels 1 and 2 is taken equal to "h" (Fig.1, 2, 3). Complete the assembly of the arch by overlapping the walls of 7 channels of 3 adjacent panels 1 and 2 of the arch to each other (Figs. 1, 4) and, using the leveling holes 8, which are available in the walls of 7 channels of 3, fix the angle of rotation of the panels in the arch, and then assemble the arch on high-strength bolts 9 or on welding 10 (figure 4).

Semi-arches in the coating can be performed both asymmetric (Fig. 1) and symmetrical sectional shapes.

With a symmetrical arrangement of the semi-arches, the ridge panel 1 is shortened and horizontal.

Panels 1 and 2 can be made straight in the length of the transport unit (up to 12 m), and arches can cover the spans of buildings up to 60 m.

According to this method, the arch can be assembled as a circular, and lancet or other shape, since the angle α in the arches is fixed by leveling holes 8.

The foundations of arches can be pinched or articulated.

The most rational field of application of the invention are arched buildings made and assembled from galvanized C-shaped profiles and transported in package packaging.
