Description

(5TH METHOD OF INSTALLATION OF LONG-DIMENSIONAL SECTIONAL CONSTRUCTIONS

one

The invention relates to construction and installation works, in particular to the installation of high-rise structures such as towers, masts, etc.

A known method of mounting structures of this type is that the structure is laid out in a horizontal position, all sections are assembled and fixed, and then they are rotated around the mounting hinge to the design position J. 1 j.

The disadvantage of this method is the need for a mounting platform of considerable size for laying out structures.

Closest to the proposed technical essence and the achieved result is a method of mounting sectional structures, including the installation of the first of the sections in the design position with a crane, connecting the remaining sections with each other and with the previously mounted hinges,

installed on their longitudinal edges, and lifting them with the help of 2 J. pulley blocks.

When installing lengthy structures in this way, it is not necessary to arrange a mounting platform of considerable dimensions for laying out structures. At the same time, the implementation of this method is possible only in the case of mounting cranes, which ensure that the construction sections are installed in the design position to a height not less than half the height of the structures.

The purpose of the invention is to simplify installation.

This goal is achieved by the fact that according to the method of installation of lengthy sectional structures, including the installation of the first section into the design position using a crane, connecting the remaining sections among themselves and with the previously mounted hinges installed on their longitudinal edges, and lifting them with the help of pulley blocks , each mounted section is additionally connected with a previously mounted section of a chain pulley mounted on a face opposite to the hinge attachment side, and with its help lift the section By turning around the hinge to a height equal to the height of the next mounted section, after fixing which and the tackle, it is moved to the design position with the subsequent disassembly of the tackle and hinge. The drawing shows the assembled structure at different stages of installation. The first section 1 of the structure is installed. They are molded to the design position with a mounting crane and secured with anchor bolts. The second section 2 is brought up by the base up into the hinge 3 of the section 1, then using the mounting crane with the help of the rod 5. one end of which is hinged to section 2, and the second is connected by polyspath 6 to the base of section 1, section 2 is turned in the hinge 3 and connect the polyspast k faces of sections 1 and the opposite faces of the hinge 3. The initial stage of lifting section 2 (coming out of the dead zone) can be carried out by a jack 7 installed at the base of section 1. Then using a chain hoop k, the next lifting is done by turning around the hinge of section 2 until the point is a ball. The peace mounting of the 8th third section 9 to the second section 2 does not reach a height equal to the height of the third section 9. The opposite faces of the second 2 and third 9 sections are connected by a hinge 8 and a polyspast 10 and continue with the help of the polyspasts and 10 further raising of the assembled sections ( 1, 2 and 9). After the point of fourth mounting section 11 to the third section 9 has reached a height h equal to the height of the fourth section 11, their opposite sides are connected by a hinge 12 and a polyspast 13.. Similarly, as the assembled sections of the structure are lifted, a connection is made between the adjacent faces of the adjacent sections by a hinge and a polyspast: sections 11 and (fourth and fifth) by a hinge 15 and polyspast 16, Lectures 1 and 17 (fifth and sixth) of the ball 18 and the polyspast 19 At the same time, joining the hinge and the polyspast of the opposite sides of the mounted sections is made after the hinge is attached to the previously mounted section with a height equal to the height of the next mounted section. . when connecting the fifth section T to the fourth section 11 and when connecting the sixth section 17 to the fifth, section 1. Lifting of the assembled sections is carried out with the help of the polyspath k, 10, 13. 16 and 19 up to the installation of all sections of the structure in the design position. As the next section of the design position is reached, it is rigidly fixed with the previous bolts, and the hitch and the hinge connecting them are dismounted. Thus, the application of the proposed method allows the use of mounting cranes of smaller capacity and with short booms when mounting lengthy sectional structures. Claims The method of installation of long sectional structures, including the installation of the first of the sections in the design position with a crane, connecting the remaining sections among themselves and with the previously mounted hinges installed on their longitudinal edges,. and raising them with the help of tackle blocks, characterized in that, in order to simplify installation, each mounted section is additionally connected to a previously mounted tackle, y & to a height equal to the height of the next mounted section, after it has been secured and the chain pulley, it is brought to the design position with the subsequent dismantling of the chain hoist and the hinge.
