Description

The utility model relates primarily to the construction industry and can be used in the overhaul or reconstruction of buildings with changes in space-planning decisions, as well as in the demolition of buildings, especially in cramped conditions. At the same time, it is often not possible to use large-sized equipment for cutting structures or to remove a part of them in such a way that they do not change their design position, and the duration of the work is not significantly increased.

There is a method of cutting reinforced concrete with a disk diamond saw [Patent of Ukraine for utility model No. 75122, IPC: E04G 23/00, published 11/26/2012], including the preliminary installation of a temporary reinforcement frame frame with screw jacks, which are included in the work of these jacks through horizontal supporting beams and on which is fixed the guides of the diamond saw. The disadvantage of this method is that fixing the guide diamond saw does not allow you to quickly change the cutting angle. That is, the technological capabilities of the described method are limited and do not allow you to quickly adjust it to different angles of inclination of the saw.

Closest to the claimed device is a device for cutting reinforced concrete structures described in the patent for a utility model [Patent of Ukraine №90734, "Method of cutting reinforced concrete structures", IPC: E04G 23/00, published 10.06.2014], taken as a prototype. The device includes inventory scaffolding with screw jacks and horizontal supporting beams, a diamond saw guide for cutting operations, the guide is fixed on the forests with tapered hinges with a clamping screw device.

The disadvantage of using such a technique is that the possibility of fixing the guide diamond saw on the reinforced concrete structure being cut is excluded, therefore, all the dynamic load is transferred to the scaffolding. The possibilities of this technology are limited and do not allow to apply it when cutting massive or curvilinear reinforced concrete structures.

Achievable technical result - improving the reliability of fixation of the reinforced concrete structure being cut, as well as expanding the technological capabilities of the device by providing the possibility of cutting horizontal massive, as well as curvilinear structural elements located at height.

The device for cutting reinforced concrete structures includes spatial scaffolding with upper and lower screw jacks, the upper jacks have a universal plug, in which horizontal supporting beams are installed, vertical intermediate pipes are mounted on the scaffolds on which, by means of hinges with a clamping screw device, fixed to move diamond saw blade with a cutting disc; in addition, this guide is additionally fixed with the cut reinforced constant design anchoring fixture, consisting of serially connected fork and ball joints with threaded terminals.

This solution allows you to cut structures with special conditions, for example, reinforced concrete beams or other structures, both massive and curvilinear, located at a height, and significantly reduce the dynamic loads transmitted to spatial forests.

The essential features of the device, coinciding with the features of the prototype, are the following:

- inventory spatial forests;

- upper and lower screw jacks;

- the top jacks have a universal plug, in which horizontal supporting beams are installed;

- intermediate pipes are installed on the scaffolding with clamps;

- on intermediate pipes there are hinges with a clamping screw device for fastening the saw blade with cutting equipment;

- equipment with a disk diamond saw for cutting structures installed on the guide to move.

Distinctive from the prototype of the essential features are the following:

- the guide is fixed with an anchor clamping device on the reinforced concrete structure being cut;

- Anchor clamping device consists of a series of forked and ball joints with threaded clamps.

The causal relationship between the set of essential features and the technical result achieved is that the diamond saw equipment on the guide is additionally fixed on the reinforced concrete structure to be cut with an anchor clamping device consisting of series-connected fork and ball joints with threaded clamps in different positions relative to the reinforced concrete structure being cut. that expands technological capabilities when performing operations on cutting, allowing It is designed to perform cutting of reinforced concrete beams or other structures, both massive and curvilinear, at a height, and also increases the reliability of fixation of cutting equipment.

Consistently connected fork and ball joints with threaded clamps give the design universal properties that ensure the fixation of elements, regardless of the initial installation on the scaffolding.

The utility model meets the condition of patentability on the criterion of "novelty", because the applicant has not found analogues that are characterized by a set of features identical to all the essential features of the claimed device indicated in the formula of the utility model.

In addition, the utility model is industrially applicable, as it can be used in the overhaul or reconstruction of buildings with changes in space-planning decisions, as well as in case of deterioration of the building, in cramped conditions.

A device for cutting reinforced concrete structure is presented graphically:

FIG. 1 - a general view of equipment for vertical cutting;

FIG. 2 - anchor clamping unit, fixed by cutting reinforced concrete structure.

A device for cutting reinforced concrete structures 1 includes inventory spatial scaffolding 2 with screw jacks in the lower 3 and upper 4 parts. The top jacks 4 have a universal plug 5 into which horizontal supporting beams 6 are installed. On scaffolding 2 two vertical intermediate pipes 7 are mounted with clamps 8. On vertical pipes 7 clamp hinges 9 are mounted and, thus, the guide 10 diamond is fixed in two levels circular saw 11 with a cutting disc 12. In addition, for rigid fastening of the guide 10, in construction 1 there is a spacer anchor 13, a fork hinge 14 is screwed on it, then a ball joint 15 with a screw clamp 16 is screwed to it. turn, the ball joint 15 is mounted on the console part of the guide 10 of the saw 11 through the bolt clamp 17.

The operation of the device is as follows. In order to ensure cutting of the structure 1 with a diamond saw 11, it should be fixed on the scaffolding 2 and construction 1. For this, the scaffolding 2 rolls under the construction 1, supporting horizontal beams 6 are installed in the forks 5 of the upper jacks 4 and using the lower jacks 3 and the upper 4 , jacking construction 1 so that in the process of cutting its elements are not shifted relative to the original position. Further, in construction 1, a spacer anchor 13 is arranged, a fork hinge 14 is screwed onto it. At this hinge, one part of the ball hinge 15 is loosely fixed, and its counterpart with a threaded clamp 16 is installed on the rail 10 through a bolt clamp 17. Both hinge parts 15 and while simultaneously adjusting the position of the bolt clip 17 and the angle of rotation of the hinge 15 in the fork hinge 14, they are fixed in such a way that the guide 10 is rigidly fixed both on the horizontal pipes 7 of the scaffold 2 and on the structure 1. Then You can make her cut.

Thus, by applying the claimed device, it is possible to more reliably fix the cutting equipment and the structure being cut, to easily dismember the horizontal elements into separate parts, to maintain them in an unchangeable position. As well as using anchoring jigs to cut massive and curved structures and reduce the dynamic loads transmitted to spatial forests.
