Abstract

The invention relates to mechanical engineering, in particular, to a method for joining thermal insulating shells with a band clamp, and can be used when installing heat insulating pipes with band collars. The purpose of the invention is to increase the reliability of the connection and the convenience of operation. The end of the band collar, divided into three parts, is placed between the heat insulating shells, bend the outer parts at an angle of 90 ° to the plane of the collar, then the ends are additionally bent and inserted into the end of the shells to be joined. After that, the clamp is tensioned, while ensuring that the shells come together and the bent parts are clamped between the ends of the shells. The bent middle is inserted into one of the perforated holes of the other end of the yoke. In this case, self-sheathing of the shells is carried out with simultaneous clamping of the embedded elements. 2 Il.

Description

The invention relates to mechanical engineering, in particular to methods for joining thermal insulating elements on pipes using band clamps.

The purpose of the invention is to increase the reliability of the connection and ease of operation.

FIG. Figure 1 shows the clamp band, in its initial state prior to assembly; in fig. 2 - connection of insulating shells with a band clamp.

The clamping yoke at one end has perforated elongated holes, which are arranged one after another. The other end of the clamping yoke is made of three Parts (middle 2 and two extreme 3) by means of longitudinal cuts 4. The ends 5 of the extreme parts 3 can be sharpened. The tie band is used to carry out the method of joining the heat insulating shells to the tube 7. The heat insulating shells 6 are made, for example, of foam and consist of two halves.

The method of combining insulating shells is implemented as follows.

One of the halves of the insulating shells 6 is installed on the tube 7. The extreme parts 3 of one end of the collar are bent along the fold line at an angle of 90 ° to its plane. Then the folded parts 3 are folded along the line of the additional bend and the folded portions 5 are inserted into the end of the insulating shell 6 (Fig. 2), and the middle part 2 is bent outwards beyond the heat insulating shell. Install the second half of the shell and cover the halves of both halves. Tension of the tape is performed, in this case mutual convergence of ethanol O is carried out.

The shells and the clamping of the bent parts 3 between the ends of the shells, after which the middle part 2 is inserted into one of the perforated holes 1 and bent.

Due to the fact that the end parts 3 are clamped between the joints (ends) of the heat insulating shells 6, tensioning the tie band eliminates the end of the tie set between the shells, therefore, the reliability of the connection increases. The stronger the tension of the yoke, the stronger the ends of the shells close together. The reliability of the joint can be increased if after placing the middle part 2 in one of the perforated holes, this part is additionally bent and inserted into the other perforated hole of the tape, which ultimately eliminates the spontaneous opening of the clamp.

According to the proposed method of joining thermal insulating shells, work can be performed directly on the object. Making the clamp is not difficult, since it can be made from a conventional galvanized sheet metal, from which tapes of the required width are cut, after which the required number of holes are punched at one end and the other end is cut into three parts by means of two longitudinal cuts. The manufacture of such a clamp does not require special equipment. In this case, using the proposed method, heat insulating shells for pipes of different diameters are secured, and special

tools for the installation of clamps and their tension, since during the tension of the clamp due to the fact that one of its ends is embedded in the end of the heat insulating shell, the shells are made as if they are self-trapping with simultaneous clamping of the embedded elements.
