Description

The invention relates to repair and construction production, in particular, to a method for dismantling pick-ups and a device for carrying it out during an overhaul, refurbishment or reconstruction of buildings and structures.

There is a known method of disassembling the overlaps on the wooden beams, chosen as a prototype, which consists in the fact that after removing the clean canopies and lag, they begin to loosen the backfill and lubricate with crowbars. The loosened backfilling and lubrication are loaded with shovel shovels onto a conveyor belt and transported to a wooden inclined chute, which is lowered into pre-prepared containers or bunkers located on the first floor level and further

transported to the city dump by road. After removing the backfill and lubrication, they proceed to the removal of the pickups. 1 The picks are also removed with the help of stowers and stored in separate piles and removed with a tower crane from the ceiling to the acquired warehouse.

A device for slinging and lifting floating objects, selected as a prototype, has a supporting guide knot and a gripping loop made of a cable with lights at the ends, coupled with the guide knot and mounted on a ship lifting device, guiding the knot contains a system of pivotally interconnected levers with locks, comprising two upper and two side levers and a spacer

a two-part bar, a gripping loop is fixed in the locks of the lever system, the upper levers are interconnected by means of a spacer bar, one of the lugs of the gripping loop is put on the bar plate, and the other is passed through the first bar and mounted on the hook of the ship's lifting device , while the end of the cable before the second light is rigidly attached to one of the upper levers. the upper arms are made with groups of holes, and the spacer bar is provided with axles matching with the openings of the upper arms.

The disadvantage of the known method and device (tools) for implementing the method is that they do not provide an increase in labor productivity by reducing the percentage of manual labor in the total amount of labor costs for disassembly,

The purpose of the invention is to increase labor productivity by replacing labor-intensive processes and reducing their number

The goal is achieved by the fact that in the method of dismantling pick-ups, which include the release of extreme areas at the supports of the beams from the backfill and rebounds, slinging, lifting and transporting to a designated place with a lifting device according to the invention, slinging rebounds is done by placing a cable with loops at the ends into the gap between the lower plane of the selections and the upper plane of the ceiling filing, installing guide units for dismantling the beams on the edges along the edges of the section to be removed, OSCAL cable ends through the eyelets of the guide assemblies an apparatus followed by the addition of their ends to a hoisting device.

This goal is also achieved by the fact that in a device for demon gas seals with backfill, including guide nodes with eyelets and cables passed through them with loops at the ends, according to the invention, guide nodes are made in the form of parallel-mounted cheeks rigidly joined between them are length-adjustable stop rods whose axes are perpendicular to the plane of the cheeks.

It is the claimed arrangement of the length-adjustable rods that are controlled by the device, the formation of volume between the device's cheek planes and the ratio of the forces of mass of the device to the forces of friction of rebounds ensure, according to the method, the charging of rebounds with filling in the specified volume and thereby

contribute to the achievement of the goal of the invention. This allows us to conclude that the claimed inventions are interconnected by a single inventive concept,

Comparison of the proposed technical solutions with the prototype made it possible to establish compliance with the Novelty Criterion. When studying other known technical solutions in this field of technology, the signs that distinguish the claimed inventions from the prototype have not been identified and therefore they provide the claimed technical solution with the criterion of significant differences.

Example. At the existing facility during complex overhaul of the house in Kiev, Saksaganskogo St. 79, after removing the parquet and black floors, the proposed method of dismantling rebounds with backfilling was applied. As a result, labor productivity increased by reducing the percentage of manual labor in the total amount of labor for dismantling pickups and backfilling. Consequently, the time taken for dismantling pickups and backfilling was reduced compared to traditional known methods,

According to the claimed method, the workflow begins with the release of the extreme sections near the supports of the girders of the supporting walls from backfill and rebounds (2-3 pickup elements). In the opened gap between the bottom plane of the pickups and the top plane of the ceiling filing, wind up the cables with loops at the ends. Install the device on two floor beams. Install cables with loops in the lugs of the device cheeks and lines to the four-vest line suspended from the crane hook. Tensioning the cables of the crane collects pickups with backfill into the volume enclosed between the parallel planes of the cheeks with cables with loops at the ends. The device together with the pickups and backfilling is transported by crane to the designated place on the construction site.

Fig, 1 shows the device with the freed extreme areas from rebounds and backfilling; in fig. 2 - installed device on two beams with slings installed; in fig. 3 - the moment of lifting the device with rebounds and backfilling.

The device for carrying out the method consists of two parallel cheeks 1, with lugs 2 attached to the upper edges, and to the lower heels 3, in the lower plane of which there are pointed teeth 4, two extreme rods 5 with adjusting washers 6, a central rod 7 with adjusting washers 6, two

plates 8 with tension sleeves 9 for adjusting them along the length and two cables 10 with loops ha ends,

The device works as follows.

At the bearing walls 11 of the building near the supports of the beams 12 of the overlap, the end sections 13 are freed from backfilling 14 and rebounds 15 (2-3 pick-up elements). In the opened slot 16, between the lower plane of the rebounds 15 and the upper plane of the ceiling cushion 17, wind up the cables 10 with loops at the ends. Using the adjusting washers 6 on the outer and central rods x 5 and 7 and the clamp sleeves 9 on the plates 8, the inner size of the parallel cheeks 1 is exposed, corresponding to the size between the beams 12 of the overlap. With the help of a crane, the device is installed on two beams 12 of the overlap, which, under its own weight, the teeth 4, which are located in the lower plane of n 3, are rigidly fixed to them. In the lugs 2 attached to the upper edges of the parallel cheeks 1, winding cables 10 with loops at the ends and lines to the four-legged sling 18. suspended from the crane hook. Tensioning the rope cables collects clips 15 along with filling 14 cables 10 with loops at the ends into the volume enclosed between the parallel planes of the cheeks 1 from the sides, the central and extreme rods 7 and 5 from the bottom and from the ends of the device.

Upon further movement of the crane's ropes, the device, together with the pickups 15 and the backfill 14, is lifted and transported to the designated place on the building site or loaded onto the vehicle.

The cycle is repeated.

Using the proposed method for dismantling pick-ups and a device for carrying it out allows, in comparison with the existing ones, to reduce the percentage of manual labor in the total amount of labor for dismantling pick-ups with backfill, therefore, labor productivity increases, i.e. the repair time of the building as a whole is shortened
