Description

The utility model relates to the field of general construction structures, to adjustable supports and to the field of electrical engineering, and in particular to supporting structures of engineering networks, communications, cable, technological and plumbing communications (pipelines).

A well-known design of a cable rack building type [Typical building structures, products and assemblies. Series 3.016.2-12. Metal structures of walk-through and non-walk-through cable racks. Developed by Kharkov PROMSTROYNIIPROEKT. Put into operation on 01/01/1992 VNIIproektelektromontazh, order dated 09/05/91 No. 32], consisting of columns / supports (racks), regalia, truss section, span structures. Procurement and assembly of the elements of the structure is carried out at the site of construction and installation works.

The disadvantages of this design are: the height of the column/support(rack) is changed only during construction and installation works by cutting or welding an additional column/support(rack). During the period of operation, there is no possibility of compensating for changes in the horizontal height position of the crossbar, truss, span structure in case of uneven settlement or bulging of the foundation from the ground, which leads to additional loads on engineering networks (communications).

The closest is the design of an adjustable pipeline support and a node for its adjustment [RU 134275 U1, IPC F16L 3/18(2006.01)]. The control unit consists of an outer pipe with fixing holes made, located with a certain pitch P in height, and an inner pipe with elements centering it relative to the outer pipe, with fixing holes made in the wall, located with the same pitch P in height and connected to the crossbar or with a lodgement by means of hinges, a nut rotatably mounted on the outer tube, a screw mounted on the inner tube, an upper pin connecting the screw and the inner tube, a lower pin inserted into the outer tube. In this case, the screw stroke inside the nut is greater than the pitch P between the fixing holes in the outer pipe and in the inner pipe, respectively. The nut is made with a stopper, which ensures the fixation of the nut relative to the screw after the end of the adjustment.

The disadvantage of this design is: the pitch P of the holes in the outer tube is equal to the pitch P of the holes in the inner tube, which fixes the adjustment step.

The task to be solved by the claimed technical solution is the development of a simple design of the control unit for the vertical elevation of the horizontal axis (in a wide range) of the supporting structure, structure and overpass not only during construction and installation works, but also during operation, as well as reducing construction lengths of engineering networks.

The problem is solved by achieving a technical result, which is to increase the safety of engineering communications during operation, networks at the design stage and during construction and installation works, by simply adjusting the elevation of the horizontal axis in a wide range.

The technical result is achieved by the fact that in a column made, for example, of a profile pipe, the fixed column is made with transverse fixing holes relative to the axis of the column with a given step, on the fixed column with holes, a movable nozzle with fixing holes is put on top of a larger profile pipe with a step holes, which may differ from the hole pitch in the fixed column. The adjustment of the vertical mark of the horizontal axis is carried out by setting the movable nozzle of the column/stand and selecting the closest alignment of the fixing holes in the movable nozzle and the fixed column/support (drain). At the set mark, coaxial holes are fixed by bolting with washers and an engraver washer.

The inventive design of the column regulation allows you to quickly set the required vertical mark of the horizontal axis, supporting structure, structure and overpass during construction and installation works and during operation, without a significant reduction in mechanical strength.

The change in the height of the column/support (rack) is known. To do this, an unregulated column (rack) of an additional rack is cut off or built up. It is also known to change the height of the column/support (rack) by coaxiality of the fixing holes of the outer and inner pipes, while the pitch of the fixing holes in the outer pipe and the inner one. However, it is not known that, in order to change the vertical mark of the horizontal axis, it is possible to use a scale of holes with different pitches in a fixed column (rack) and in a movable nozzle. Changing the elevation of the horizontal axis is carried out by selecting the alignment of the holes. The design of the unit for adjusting the vertical mark of the horizontal axis of the column (in the framework of this solution it can be a support, a rack) of a structure, a flyover consists of a fixed with holes with a given pitch, a movable nozzle with holes with a given pitch, which is equal to or greater than the pitch of the fixed column, bolted connections and headline.

The adjustment of the vertical mark of the horizontal axis is carried out by moving the movable nozzle with holes along the vertical axis of the fixed column / support (rack) until the holes between the column and the nozzle coincide and then rigidly fixing the assembly with bolted connections.

To do this, holes with a certain pitch are made in the fixed column, holes are drilled in the nozzle with a pitch that differs from the pitch of the holes in the column.

With this design of the node, the height of the mark of the horizontal axis of the column / support (rack) is regulated with a minimum discreteness, while maintaining the mechanical strength of the entire support, structure and flyover, and, therefore, the structure or flyover can be made on one vertical mark of the horizontal axis, while the difference in marks heights of columns (racks) is reduced to a minimum, and consequently, the length of communications as a whole is reduced. The presence of bolted connections provides the ability to adjust the elevation of the horizontal axis during the operation when performing repairs.

In FIG. 1 shows the profile of the overpass, the crossbar repeats the ground level.

In FIG. 2 shows the profile of the cable rack, the crossbar is laid at one mark, along one horizontal line.

In FIG. 3 shows a structure that adjusts the vertical mark horizontally to the axis of the support, the overpass of the structure.

In FIG. 4 shows the structural elements that regulate the vertical mark horizontally to the axis of the support, the overpass of the structure.

The main provisions of the physical nature of the control structure of the vertical axis of the flyover are as follows:

1. Ground level - variable;

2. When rounding the overpass of the ground level, there is an increase in engineering networks (for example, cable lines, communication lines, technological communications);

3. With different hole pitches on the fixed column (rack) and the movable nozzle, it is possible to achieve regulation of the overpass height while maintaining mechanical strength;

We will show the possibility of regulating a column consisting of a fixed column (rack) with a hole pitch - X1 and a movable nozzle with a hole pitch - X2.

Design justification

1. Ground level.

On the unorganized surface of a piece of land, the ground level marks are very different.

Altitude differences in the marks of the earth's surface vary in a wide range and can reach up to several meters or more.

2. Influence of elevation differences in ground marks on the length of engineering communications

The length of engineering networks is determined as the sum of the length of the horizontal route and the vertical drops of the flyover.

While maintaining the horizontal level of the overpass relative to the first column, it allows minimizing horizontal differences in elevations and thereby reducing engineering networks.

On the example of a cable overpass, we will consider the lengths of cable lines for the option of a flyover made with an envelope around the ground level, and for the option of a flyover with the absence of these drops.

The length of the cable line on the overpass can be determined by the expression:

where L _cl - the horizontal length of the overpass route, m;

h _cl - the sum of the vertical drops of the cable rack, m;

l _cl \u003d (L _cl + h _cl ) × 2% - the length of the cable line per snake, 2% of the sum of the horizontal and vertical lengths, m;

Table 1 shows an example of calculating the length of a cable line in two versions.

The first option - the horizontal crossbars of the flyover go around the ground level at a height of the horizontal axis of 2.5 m.

The second option - the horizontal crossbars of the overpass are not tied to the ground level; the elevation of the horizontal axis is tied to the first column, support (rack).

Table 1. Calculation of the length of communications for option 1 and option 2 of the flyover Parameter Option 1 Option 2 Horizontal length of the overpass route, m 120 120 Number of columns, pcs 60 60 Average height difference, m 0.1…1 - Vertical drop overpass, m 6…60 - Cable line length per serpentine, m 2.52…6.48 2.4 Total length of the cable rack 128.52…186.48 122.4 Reducing the length of the cable line relative to option 1,% 5…52.3

An analysis of the options in the considered example shows that adjusting the elevation of the horizontal axis of the column / support (rack), overpass, in order to maintain one horizontal level, leads to savings in engineering systems, according to the example - the length of the cable line is reduced in the range from 5 to 52, 3%.

2. Adjustment range of the claimed design

The range of adjustment of the vertical mark of the horizontal axis is determined by the expression:

где N1 - количество отверстий в неподвижной колонне (стойке), шт;

where N1 is the number of holes in the fixed column (rack), pcs;

n1 is the ordinal number of the hole in the fixed column (rack), the ordinal number starts from 0;

X1 - hole pitch of the movable column (rack), cm;

N2 - number of holes in the movable nozzle, pcs;

n2 is the ordinal number of the hole in the movable nozzle, the ordinal number starts from 0;

X2 - hole pitch of the movable nozzle, cm;

L - the distance between the extreme holes n1 and n2, when docking a fixed column (rack) with a movable nozzle in the holes - 0 and n2, respectively (the distance between the extreme holes n1 and n2, without extending the node), cm

The table shows an example of the vertical axis adjustment range.

The initial data for the example are given in Table 2.

Let's show in table 3 the operation of the structure of the control unit for the vertical elevation of the horizontal axis of the support, structure, overpass with several ratios of the coaxiality of the holes n1, n2.

Table 3 shows just a few of the hole alignment options available.

Thus, from the combinations of the alignment of the holes of the fixed column (rack) and the movable nozzle considered in Table 3 in the considered example, the control range is from 2 cm to 50 cm.

The claimed design allows you to quickly and easily adjust the elevation of the vertical axis while maintaining mechanical strength during construction and installation works and during operation.
