Abstract

A bell-shaped connection with a gap between the mating surfaces of the socket and the end of the pipe filled with a sealing compound, characterized in that on the outside of the connection along its perimeter along the matching axes are made paired tables, connected to each other on the mounting, each of which is fixed to the mating ends of the pipes, while the plane of the tables coincide and oriented across the pipe.

Description

The utility model relates to the field of construction and can be used primarily for connecting sections of the exhaust pipes of chimneys and ventilation pipes made of polymer composite materials.

It is known to connect pipes having a socket at one end into which the opposite end of the mating pipe is inserted with a gap through an elastic seal [1]. The disadvantage of this solution is the difficulty of mounting and ensuring the tightness of the connection due to possible eccentricities, the need for elastic deformation of the sealant and possible roughness of the mating surfaces, as well as the impossibility of transmitting axial forces.

Closest to the technical nature of the claimed object is a bell-shaped connection of predominantly vertically mounted and suspended separately to the supporting structures, for example, trellised towers, sections (casing) of the exhaust pipe from pipes with upwardly facing bell, into which the lower end of the above pipe is inserted with a gap, this gap between the mating surfaces of the end of the pipe and the socket is filled with a sealing compound [2].

Replacing an elastic sealant with a sealing compound facilitates installation, however, such a connection also cannot absorb axial forces, especially during installation.

The utility model solves the problem of ensuring the transmission of axial force.

To do this, in a socket connection with a gap between the mating surfaces of the socket and the end of the pipe, filled with a sealing compound, according to the utility model, on the outside of the connection along its perimeter along matching axes are made paired tables for mounting, each of which is fixed to the mating ends of the pipes and the plane which coincide and are oriented across the pipe.

Figure 1 shows a longitudinal section of a socket connection, figure 2 is a section 1-1 of figure 1, figure 3 is a section 2-2 of figure 1.

The bell-shaped connection comprises connecting pipes 1 and 2, the end of the pipe 2 has a socket 3, into which the end without a socket of the mating pipe 1 enters with a gap 4. The gap 4 between the mating surfaces of the end of the pipe 1 and the socket 3 is filled with a sealing compound 5. To the mating ends of the pipes 1 and 2 along the perimeter of the socket connection, outside it, paired tables 6 and 7 are installed along the coincident axes, the planes of which coincide and are oriented perpendicular to the pipe or at an angle to it. Each of the tables 6 and 7 is fixed, for example, using rings 8 and brackets 9, to the mating ends of the pipes 1 and 2. To prevent leakage from the joint when filling the sealing compound 5, a plug 10 is installed at the end of the pipe 1, for example, of soft material. Paired tables 6 and 7 are interconnected during the installation of pipes 1 and 2, for example using bolts 11.

The device operates as follows.

Before installation, during the control assembly of the joint, rings 8 with brackets 9 and tables 6 and 7 are installed on the joint, combining the axes of the tables and their planes. Then the tables 6 and 7 are temporarily connected by bolts 11, the end of the pipe 1 is centered in the socket 3, after which the rings 8 are fixed at the ends of the pipes 1 and 2, for example by gluing. After this, the joint is disassembled and the pipes 1 and 2 are sent for installation. It is possible to fix tables 6 and 7 using brackets 9 and rings 8 to the ends of pipes 1 and 2 without a control assembly, according to the template, in the manufacture of pipes. To obtain the connection, the end of the pipe 1 is introduced with a gap 4 into the socket 3 of the pipe 2, combining the paired tables 6 and 7 and connecting them with bolts 11, while at the same time the centering of the end of the pipe 1 in the socket 3 occurs. After that, the connection can already absorb axial loads , for example, from its own weight, by transferring force from the pipe 1 to the pipe 2 through rings 8, brackets 9 and tables 6. In this case, the compression force is transmitted by the emphasis of the table 6 to the table 7, and the tensile force

for example, from wind load, through bolts 11. After this, the gap 4 is filled with sealing compound 5. When using a curable strong sealing composition, for example, polymer resin with fiberglass filler, it receives part of the axial loads during operation, helping the rings 8, brackets 9, tables 6 and 7, of the bolts 11. In addition, the shells of the bell-shaped part 3 and the end of the pipe 1 included in the bell after filling with the sealing compound 5 can be connected by radially mounted additional ny ties, for example screws.

Compared with the prototype of the inventive socket connection is able to absorb axial loads.
