Description

Technical field

The utility model relates to the field of construction, namely to reinforcing cages for reinforced concrete and other structures.

State of the art

The following methods are known from the prior art for connecting reinforcing bars in the manufacture of reinforcing products:

- by the method of arc or contact electric welding;

- on twists by knitting wire manually or using knitting guns;

- staples using staplers;

- with the use of fixing elements.

The disadvantages of these methods are:

- the great complexity of the work, caused by the need to fix each connection manually;

- the availability of expensive welding equipment and knitting guns;

- the need to use consumables - electrodes, knitting wire, connecting elements;

- the need to use special equipment for precise positioning of reinforcement and reinforcing products when they are connected.

The closest analogue of the claimed utility model is a reinforcing cage containing reinforcing elements connected by crimping one rod around another around the circumference (see, for example, RF patent RU2121046, 10.27.1998, publication of international application WO9212303, 07.23.1992, UK patents GB766259, 01/16/1957, GB1051215, 12/14/1966, German application DE2434079, 02/05/1976).

However, from a technological point of view, bending the rod around the circumference is a complex process even when using CNC machines with 3D heads. In particular, when bending the bar by the rolling method, the roller rolls the bar around the bending tool, and with the radius that the bending tool has. Therefore, for bending reinforcement along a different radius, it becomes necessary to replace the bending tool, which is associated with stopping the operation of equipment for readjustment.

A more universal method of bending is pushing, in which the rod is fed forward, and the rolling roller sets the degree of deformation on the bending tool, which results in one or another bending radius. However, bending by the pushing method does not allow forming a bending radius of less than five rod diameters, which creates additional technological difficulties.

 Utility Model Disclosure

The objective of the claimed utility model is to eliminate the disadvantages of analogues and to develop a simple to manufacture and assemble the structure of the reinforcing cage.

The technical result of the utility model is to reduce the complexity of manufacturing a reinforcing cage while maintaining its strength characteristics.

The specified technical result is achieved due to the fact that the reinforcing cage contains interconnected reinforcing elements, while the first reinforcing element encircles the second reinforcing element, and in the circumference zone a fragment of the first reinforcing element is curved in the form of an open polygon with an open sector, the width of which is less than the diameter of the second reinforcing element.

In addition, according to private options for implementing the utility model:

- the width of the open sector of the first reinforcing element and the diameter of the second reinforcing element enable the second reinforcing element to move through the open sector into the inner contour of the curved fragment of the first reinforcing element,

- a fragment of the first reinforcing element may be curved in the form of an open triangle or quadrangle.

- the second reinforcing element may be a reinforcing bar, and the first reinforcing element is a connecting element of the frame.

- the first reinforcing element itself is made curved (and not only its fragments in the girth zone),

- the frame can be made flat or three-dimensional.

Unlike the closest analogue in the claimed reinforcing cage, the reinforcing elements are connected with the formation of a girth zone of one element by another in the form of an open polygon (triangle, quadrangle, etc.), which is more versatile and technically easy to do when bending rods, in particular, by running in. Moreover, such a reinforcing cage in a finished reinforced concrete structure in terms of strength characteristics is not inferior to the closest analogue, as well as welded frames used in the production. In addition, there is no need to replace equipment when bending connection nodes for crimping reinforcing bars of various diameters. Thus, the proposed design allows to reduce the complexity of manufacturing and assembling the frame while maintaining its strength characteristics.

Utility Model Implementation

The claimed frame includes at least two reinforcing elements (1) and (2) of circular cross section, interconnected so that the first element (1) encircles the second element (2). Under the reinforcing element in the framework of this application refers to a rectilinear or curvilinear element of the reinforcing cage, made of a rod ("rod" element). In the girth zone, fragment (3) of the first element (1) is curved in the form of an open polygon. The most preferred forms of bending of the fragment (3) of the first element (1) are an open triangle (Fig. 1) and a quadrangle (Fig. 2). Moreover, fragment (3) has an open sector (4), the width (C) of which is less than the diameter (D) of the second reinforcing element. This is necessary in order to ensure reliable fixation of the elements. Preferably, the width (C) of the open sector and the diameter (D) of the second element allows the second reinforcing element (2) to move through the open sector (4) into the inner contour of the curved fragment (3) of the first reinforcing element (1).

The bending of the reinforcing elements is preferably carried out by running-in.

The following are possible options for implementing the utility model.

In FIG. 1 shows the connection node of two reinforcing elements in the form of a reinforcing bar and a connecting element. The reinforcing bar (second reinforcing element - 2) is crimped by a fragment (3) of the connecting reinforcing element (first reinforcing element 1). The indicated fragment (3), forming a girth zone, is curved in the shape of a triangle, at the top of which there is an open sector (4). The width (C) of the sector (4) is slightly smaller than the diameter (D) of the reinforcing bar (2). In this case, it is possible to advance the reinforcing bar (2) through the open sector (4) into the inner contour of the fragment (3) of the connecting element (1), thereby connecting the reinforcing elements (1,2).

In FIG. 2 shows a similar section of the connection node, with the fragment (3) having a quadrangular shape, and an open sector (4) is made at one of the vertices of the specified quadrangle.

In FIG. 3 shows a cross section of a flat reinforcing cage (5), consisting of two reinforcing bars (second reinforcing elements 2) and a connecting element (first reinforcing element 1).

In FIG. 4 shows a cross-section of a reinforcing cage in the form of a triangle 9 consisting of three reinforcing bars (2) and connecting elements (1), the connecting fragments (3) of which are curved in the form of triangles.

In FIG. 5 shows a cross section of a reinforcing cage (5) with four reinforcing bars (2) and connecting elements (1), curved into the quadrangular in the frame.

In FIG. 6 shows a cross section of a reinforcing cage (5) with four reinforcing bars (2) and connecting elements (1) curved outward of the cage in the shape of a quadrangle.

The connection of the reinforcing bars (2) and the connecting element (1) is carried out in the inner contour of the connecting element by the way of moving the reinforcing bars (2) into the open sectors (4) in the direction from the center of the rectangular connecting element (1) to its corners.

Multifaceted reinforcing frames can be made with any number of faces and any number of reinforcement on each face of the frame.

In FIG. 7 shows a cross section of the connection of the embedded part (6) with reinforcing bars (2). The embedded part (6) consists of a plate (7) made, for example, of steel, and connecting elements (1) welded to the plate (7). At the junction of the embedded part (6) with reinforcing bars (2), the connecting elements (1) have fragments (3), curved in the shape of a triangle with an open sector. The connection of the embedded part (6) with the reinforcing bars (2) is carried out by the method of crimping the reinforcing bars with fragments (3) of the connecting element (1).

In FIG. Figure 8 shows a cross-section through the connection of an anchor bolt (8) with reinforcing bars (2). The connecting element (1) is welded to the anchor bolt (8).

In FIG. 9 and 10 show a flat reinforcing cage (5) consisting of two reinforcing bars (2) and a connecting element (1) having a V-shape. The use of connecting elements of this form increases the rigidity of the reinforcing cage.

In FIG. 11a shows a cross section of a reinforcing cage consisting of reinforcing bars (2) and a connected element (1). In this case, the reinforcing bars (2) are located in two different planes of the reinforcing cage. The upper and lower planes of the reinforcing cage are parallel to each other. The connecting element (1) has the form of a flat continuous W-shaped reinforcing route. The upper and lower curved fragments (3) of the wave crest of the connecting element (1) have the form of a triangle with an open sector at the apex. The reinforcing bars (2) are connected by the method of their advancement to the open sectors (4) of fragments (3).

In FIG. 11b shows a similar connection option, while the open sectors (4) in the upper and lower bends of the wave crests of the connecting element (1) are directed in one direction, which increases the ease of assembly.

In FIG. 12-14 shows a frame with a connecting element (1) in the form of a clip-retainer. The upper fragments (3) curved in the shape of a triangle fix the upper reinforcing bar (2). Next, the connecting element bends down 180 ° on both sides, being in the plane of the fragments (3), in the direction of the lower reinforcing bar (2). Before reaching it, the connecting element (1) forms bends directed towards the longitudinal axis of the lower reinforcing bar (2). Descending below, the connecting element covers the lower reinforcing bar with lower triangular bends. The process of connecting reinforcing bars in this case occurs as follows: the lower reinforcing bar (2) moves into the open sectors of the lower bends and is fixed on both sides; after that, the upper reinforcing bar moves into the open sectors of the upper bends.

The presented examples of the implementation of the design are given to illustrate possible embodiments of the utility model, which, however, are not limited to the information specified in the description.
