Description

DEVICE FOR LIFTING A BRIDGE BEAM

The utility model relates to bridge building and can be used in the repair of the support zone of a bridge beam or bridge support.

Famous book (textbook) auth. Suleymanov M.K., Sabiryanov R.R. "Rigging and rigging in construction and industry." Chapter 5 Performance of work, paragraph 5.5. “Instead of special lifting devices, you can use conventional ropes for slinging various construction materials for single lifting by knitting them into knots and loops.” “To protect the ropes from rubbing when tying goods with sharp edges, safety pads should be installed.” “When laying the load on loop slings its movement (regardless of the number of loops on the sling) is allowed only if there are elements that prevent displacement in the longitudinal direction. ”“ When moving rope slings and goods with sharp ribs, it is necessary to place gaskets between the ribs and ropes, which protect the latter from damage. Gaskets are made of wood, cut pipes, rubber-fabric hoses, flat belts, etc. ”Fig. 5.1. "B"

The disadvantage of this method is the difficulty of installing the sling ropes and the instability of the beam when lifting.

The closest (prototype) to the claimed utility model is the patent for the invention of the Russian Federation No. 1823892, IPC E01D 21/02 "Lifting device of beams of the span of the bridge to replace the supporting parts." The invention includes a hydraulic cylinder and

one

elements of vertical movement, which are made in the form of support racks and traverse with flexible rods. Racks are placed symmetrically relative to the supporting sections of the beams, and their upper ends are passed through the holes formed in the beams and are interconnected by a cross member. The hydraulic cylinder is placed between the traverse and the cross member, and flexible rods are connected to the beams.

The disadvantages of this method is that for the implementation of the lifting requires the installation of additional equipment, as well as the grinding / breaking of flexible rods may occur.

The objective of the invention is to reduce labor costs for raising the beam of the bridge with the provision of tight fixation of the beam of the bridge.

The problem is solved due to the fact that the device for lifting the beam of the bridge includes a support beam, flexible cables and an auxiliary device for fixing the lower edge of the vertical wall of the beam. The device for lifting the beam of the bridge further includes an auxiliary device for fixing the lower edge of the vertical wall of the beam, made prefabricated, and consisting of an element for capturing the lower edge of the vertical wall of the beam, an element of direction and retention of the flexible cable, as well as an additional element. The capture element of the lower edge of the vertical wall of the beam is made in the form of an inverted U-shaped sectional element. The element of direction and retention of the flexible cable is made in the form of an arcuate in longitudinal and transverse section of the element with a groove oriented outward. An additional element is made in the form of metal shapes.

The essence of the invention is illustrated by drawings where:

In FIG. 1 - The rise of one of the non-extreme beams and the damaged supporting and supporting zone of this beam are depicted.

In FIG. 2 - The rise of one of the extreme beams and the damaged supporting and supporting zone of this beam are depicted.

In FIG. 3 - shows an auxiliary device for fixing the lower edge of the vertical wall of the beam.

In FIG. 4 - An element of a beam with a traverse, a device for fixing the lower edge of the vertical wall of the beam, a tensioned cable and an installed jack is shown.

A device for lifting 1 of the beam of the bridge 2, includes a support beam 3, flexible cables 4 and an auxiliary locking device 5 of the lower edge 6 of the vertical wall of the beam 7. (see. Fig. 3, 4)

The device for lifting 1 of the bridge beam further includes an auxiliary locking device 5 of the lower edge 6 of the vertical wall of the beam 7, made prefabricated, and consisting of a gripping element 8 of the lower edge 6 of the vertical wall of the beam 7, an element of direction and holding 9 of the flexible cable 4, as well as an additional element 10. The gripping element 8 of the lower edge 6 of the vertical wall of the beam 7 is made in the form of an inverted U-shaped cross-section of the element 11. The element of direction and holding 9 of the flexible cable 4 is made in the form of an arcuate in the longitudinal and the cross section of the element 12 with the groove 13, oriented outward. An additional element 10 is made in the form of metal shapes 14 (see Fig. 1, 2, 3, 4)

Work on lifting the beam of the bridge is performed in the following sequence:

3

1. Make an auxiliary device 5, consisting of a gripping element 8 of the lower edge 6 of the vertical wall of the beam 7, an element of direction and retention 9 of the flexible cable 4 and an additional element 10.

2. The support beam 3 is installed across the beam of the bridge 2.

3. Drill holes 15 in a horizontal plate 16 of the beam of the bridge 2, and holes 15 are drilled symmetrically to each other on the right and left relative to the vertical wall of the beam 7.

4. Install the auxiliary fixation device 5 of the lower edge 6 of the vertical wall of the beam 7, and it is installed on a free from contact with the support space in the same plane with the support beam 3.

5. Pull the flexible cable 4 (rope) so that the flexible cable 4 passes through the holes 17 of the support beam 3 and the holes of the horizontal plate 15 of the beam of the bridge 2, while covering the auxiliary device 5 through the groove 13, and the ends of the flexible cable 4 come out, on top of the support beam 3.

6. Install the single-strand jack 18 on the support beam 3, so that the single-strand jack 18 covers one of the outgoing ends of the flexible cable 4.

7. Raise the beam of the bridge 2 by pulling the flexible cable 4 with a single-strand jack 18.

The task of reducing labor costs for raising the beam of the bridge with the provision of tight fixation of the beam of the bridge is solved by using the proposed auxiliary fixation device.

Industrial applicability is that for the manufacture of an auxiliary fixation device used

four

improvised materials, it is also simple in execution and convenient to use and allows to achieve high accuracy when lowering and installing the beam on a support.

When using the proposed auxiliary fixation device, work on raising the beam can be carried out while maintaining movement on the bridge, since the lifting of the beams is carried out alternately, first on one side of the traffic, then on the other.

All of the above indicates a solution to the problem, namely: reducing labor costs for raising the beam of the bridge with the provision of tight fixation of the beam of the bridge.
