Abstract

Use: in construction for the connection of concrete products. The connecting piece contains a plate-shelf with a perpendicular edge, the length of which is equal to the length of the plate and half the length, with holes parallel to the plate in the edge for connecting to the reinforcement of the concrete product and the hole for the concrete key These bolts are oval-shaped in a plate, one of which is parallel to the axis, the other is perpendicular, or both at an angle of 45 °. 1 hp f-ly, 4 ill.

Description

The invention relates to the field of construction and relates to the construction of a connecting part for connecting in the straight-line direction two prestressed concrete products, such as interior wall panels, airfield road slabs and floor slabs of multi-storey large-panel buildings and other products.

The closest in technical essence is a connecting part comprising a plate-shelf with two holes for the clamp bolts and a rib, perpendicular to the plate-shelf with two cylindrical holes.

The disadvantage of this connecting part is that it does not have any rigid connection with the tensioned string fittings at the moment of transfer of the load from one plate to another, which creates the possibility of knocking-out a piece of concrete with a fixed inlay, t. e. there is no joint connection in operation with the tension string fittings at the moment of transferring the load from one panel to another and there is no rigid connection between the connected parts of the other plate due to the long bolt length, which can create a backlash.

The purpose of the invention is to provide the possibility of using it to rigidly connect panels with a tensioned string armatura when the connecting parts themselves deviate by +30 mm from the design position, both in height and width of the panel.

The goal is achieved by the fact that the connecting part comprising a plate-shelf with two holes for clamp bolts and an edge perpendicular to the plate-shelf with two cylindrical holes, the holes in the plate for clamp bolts are longitudinally elongated and arranged obliquely at an angle

and parallel to each other or one along the axis of the plate, and the other across, with a hole formed under the rib under the concrete bridge, and cylindrical holes are made to connect the part with the outlets of the inner anchors and are located at the same distance parallel to it

the width of the plate can be equal to 0.4–0.45 of the thickness of the panel, and its length can be two widths plus the thickness of the rib.

Fig. 1 shows a connecting fixture, a view of the rear part with oval inclined connecting holes; figure 2 is the same, side view of figure 1; on fig.Z - the same, top view on figure 1; Fig. 4 shows the same, with oval connecting holes, one of which is vertical and the other horizontal.

The connecting piece consists of a plate-shelf 1 with an edge 2) there are two holes 3 through which this connecting piece, wound into the intervals between the releases of the inner anchors, is connected with fingers with the releases of the inner anchors (not shown) on which the fittings are wound . The connecting piece has openings 4, openings for clamp bolts for a rigid connection. Holes 4 can be located at an angle of 45 ° or one - vertically, and the other - horizontally. A hole 5 is made in the rib 2, which makes it possible to form a web in the grouted concrete solution.

This design of the connecting part makes it possible to rigidly connect two plates or walls in a straight line, tightly pressing the connecting parts to each other. The fastening of the connecting part to the inner anchor releases, on whose shells continuous stringed reinforcement is wound, makes it possible for the tapped reinforcement of the upper row to work together with the lower one, avoiding pulling out the anchor, and the concrete, which holds the anchor, does not break.

Making the holes 4, having an oval shape, and arranging them in an inclined form or in a horizontal and vertical position, creates

the ability to assemble reinforced concrete products when the connecting parts of the products or concrete products themselves deviate from the design position with tolerances of ± 30 mm.

This design of the connecting part makes it possible to completely displace the welding operation, which is not allowed when string reinforcing in pre-stressed reinforced concrete products, thus increasing the

labor productivity during the installation of concrete products.
