Abstract

SUMMARY OF THE INVENTION: The framework of an arched building contains single end and regular arches installed on the foundation with equal pitch and formed from at least three of the same type of arched sections connected by bolts through flanges. The linear arches in the supporting part are made of paired parallel sections, and in the span - single unary. Each section is designed for a force of no more than half of the calculated force in the arch in the installation zone of paired sections and not less in the zone of single sections of the arch. Bolts located in the holes of a single section are installed in adjacent rows of holes in the paired sections of 1 Cp. f-ly, 4 ill.

Description

The invention relates to construction, in particular, to lightweight arched buildings with a span of 9 - 24 m, used as shelters, warehouses, parking spaces, etc.

The arch framework of the arched building, including the arches of a curvilinear outline, the girders laid along the upper along the arches and the transverse connections of rigidity along the ends of the building, is rooted. All the arches in this building are made of four of the same type of lattice sections, interconnected through flanges by bolts.

The framework of the arched building is known, including curvilinear arches of variable cross section, arch runs and stiffness linking system.

Closest to the proposed technical essence and the achieved effect is the framework of the arched building, which includes arches of curved sections of the same type, connected by bolts through flanges, arch runs and stiffness ties along the ends.

A disadvantage of the known frame is that while maintaining the manufacturability of the arches mounted from the same type of sections, metal saving is not ensured.

The purpose of the invention is to reduce material consumption per arch.

In the framework of the arched building, including single and regular, installed on the foundation with equal pitch of the arch, and made of at least three of the same type of arched sections connected through flanges by bolts, runs and connections of stiffness, regular arches in the support part are made from paired parallel sections, and in the span span - from one pair, each section being designed for a force of no more than half of the calculated force in the arch in the area where the sections are installed and not in the zone of single sections of the arch, while You, located in the openings of the single section, are installed in adjacent rows of openings in the paired sections.

between the axes of the joint sections is equal to twice the distance between the axes of the extreme rows of holes of the flanges of the sections.

FIG. 1 shows a fragment of the framework of an arched building (runs are conventionally shown only between two arches), axonometrics; in fig. 2 - version of the same type of articulated arched section, general view; in fig. 3 shows a mounting unit for paired sections of a row arch, followed by a single section; node I in FIG. one; in fig. 4 - section mounting unit, view A in FIG. 3

The framework of the arched building includes face 1 and a series of 2 arches installed on the foundation 3, girders 4, and stiffness connections 5. The end 1 and row 2 arches are made of uniform sections (Fig. 2), consisting in the case of the lattice section of the upper 6 and lower 7 along with brackets for fastening the purlins 8, diagonal bars 9 and the flanges 10 with bolt holes 11 and traverses 12.

The framework of the arched building is implemented as follows.

Similar sections are made (Fig. 2) for the end and end arches. All elements of these sections are designed for forces no more than half of the calculated forces in a regular arch in the installation zone of paired sections, and no less than for forces in the zone of single sections. From single sections, front arches 1 and two arches 2 are mounted in the support areas from parallel-installed paired sections, and in the span section - from single sections. At the same time, the paired sections are installed with a distance between the b and 7 themselves, equal to twice the distance a between the extreme rows of the flange holes 10. During the mounting process of the arches, stiffness links 5 and runs 4 are installed.

The arch frame building constructed by the proposed method ensures the use of only one-type sections for arches, while the material consumption for this section is 1.8-2 times less than in known ones, with their number in a real building 1.3-1.4 times more. The material savings on the frame as a whole is 30 - 40%.

The frame of the lightened building is advisable to use when spans of 9–12 m with an arch lifting boom equal to 0.3–0.5 of the span, mainly with circular arches.
