Abstract

FIELD: construction.

SUBSTANCE: method comprises the assembly of arches in horizontal position from the same elements by the hinged connection of their ends to the joint plates by central bolts, giving arches the desired shape, rigid fixation to the joint plates, subsequent installation of arches into the design position, installation of hammer beams on arches and laying the fence on them. Joint plates are made of segments of thin-walled rectangular or square pipe, and the ends of the same elements are placed inside the joint plates, on the upper and lower shelves of which longitudinal and transverse slots with formation of cantilever portions are made. These portions are bent up until the contact with the shelves of the ends of the same type elements with provision of the required outline of the arch and subsequent installation of self-drilling bolts between them.

EFFECT: improved strength and stiffness of joint connection of arch elements.

Description

The invention relates to the field of construction, and in particular to methods of erection of lightweight arched buildings with arches of the same elements.

There is a method of erecting a lightweight arch building, including assembling arches from the same type of starting elements, installing them at a certain interval, attaching the girders to them and laying them along the girders of the fence from separate curved profiled sheets [Railway Industrial Construction, No. 5, 1986, p. .18-20].

A disadvantage of the known installation method is that it is not possible to change the shape of the arches when installing the arches, since the elements of the same type are interconnected through flanges attached to their ends at a constant angle. The inability to change the shape of the arches reduces the versatility and does not allow to realize the optimal shape of the arch.

There is another way to erect an arch building from the same type of elements, including a rectilinear element, a concave and annular gusset at the ends with coaxial holes. The erection of the building consists in assembling the arch of the required shape by combining the holes in the annular and concave faces of the adjacent elements and installing fixing bolts. After assembling the arch, they are connected by girders, along which the fence is laid [Express information. Construction and architecture. Series 8. Building structures. Issue number 7. VNIIS Gosstroy of the USSR. 1984, p. 2-5].

A disadvantage of the known method of erecting an arch building is the great complexity of manufacturing structures of the same type of elements and the limited ability to control the angle of connection of the arch elements due to the discreteness of the coaxial holes.

Closest to the invention is a method of erecting an arch building, including assembling arches in a horizontal position from the same thin-walled elements by hinging their ends to the gussets with central bolts, giving the arches the desired shape and finally rigidly fastening the gussets with self-drilling bolts placed in circles around the central bolts, the subsequent installation of arches in the design position, the installation of girders on the arches and the installation of fencing on them [Patent RU No. 2423581. IPC E04B 1/32, E04B 1/58. Bulletin No. 19 of July 10, 2011].

A disadvantage of the known method of erecting an arch building is the insufficient strength of the junction of the same type of elements and its low rigidity from the plane.

The invention is aimed at increasing the strength and rigidity of the nodal connection of the same type of arch elements.

The result is achieved in that in the method of erecting an arched building, which includes assembling arches in a horizontal position from the same type of elements by hinging their ends to the gussets with central bolts, giving the arches the desired shape and final rigid fixation to the gussets by installing self-drilling bolts arranged in circles around the central bolts, the subsequent installation of the arches in the design position, the installation of runs on the arches and the installation of fencing on them, according to the invention of the fittings of segments of thin-walled rectangular or square pipes, and the ends of the same type of elements are placed inside the gussets, on the upper and lower shelves of which longitudinal and transverse slots are made with the formation of cantilevered sections that bend until the ends of the same type of elements are in contact with the shelves, ensuring the required outline of the arch and the subsequent installation between them self-drilling bolts. It is advisable to bend the cantilever sections of the shelves by turning the same type of elements when setting the desired shape.

Figure 1 shows a cross section of an arched building with arches of six elements of the same type. Figure 2 shows the connection node of the same type of arch elements (node A in figure 1). Figure 3 is a section I-I of Figure 2. Figure 4 shows the nodal gusset during the bending of the cantilever sections of the upper and lower shelves.

The arched building consists of arches assembled from the same type of elements 1, gussets 2, attached to the ends of the same type of elements 1 with the help of central bolts 3 and self-drilling bolts 4. The shapes 2 are made of pieces of thin-walled rectangular or square pipes in which longitudinal and transverse cuts with the formation of cantilever sections 5, and elements of the same type 1 arch - from paired thin-walled C-shaped profiles or bent closed profiles. The arched building also includes girders 6 and the fence 7, stacked along the girders 6.

The erection of an arched building is as follows. In a horizontal position, the ends of the same type of elements 1, made of paired thin-walled C-shaped profiles or bent closed profiles, are placed inside the gussets 2, the upper and lower shelves of which have cantilever sections 5, and are attached using central bolts 3. Then, the required outline of the arch is set up by turning the elements 1 around the central bolt 3, while the cantilever sections of the shelves 5 of the fittings 2 are bent until the ends of the elements of the same type 1 are in contact with the shelves. After that, the ends of the same type of elements 1 are finished but fixed to a luminaire by installing two self-drilling screws 4, mounted circumferentially around the central bolt 3. The collected arch installed in the design position, the collected arches mounted and fastened girders 6 and 6 laid on joists fence 7.

The invention improves the strength and rigidity of the nodal connection of the same type of arch elements.
