The invention relates to the construction, in particular to the construction of multi-storey frame buildings of reinforced concrete elements.

The purpose of the invention is to simplify the installation of the joint.

FIG. Figure 1 shows the proposed junction of elements of the building framework, side view; in fig. 2 is a section A-A in FIG. one; FIG. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

Butt connection of crossbars 1 with column 2 includes the following. In the upper zone there are embedded mortgage parts 3, welded to its supporting working reinforcement 4, additional embedded parts 5, working reinforcement outlets 6 bolts, to the free ends of which at the ends rigid support elements 7 are attached, connecting rods 8 with welded ends from their ends from the side of the crossbars, plates 9, fixed on the embedded parts x 3 columns, clamps 10, covering the connecting rods at the ends, and horizontal 11 and vertical 12 clamps,

In the lower zone of the junction, side bars 13 are installed, welded to the working reinforcement of the column, to which support bars 14 are rigidly attached to the bottom, and thrust plates 15 placed laterally from the crossbars side, arranged in increments along the length of the side bar.

Mounted parts 16 and additional vertical clamps 17 are installed on the side of the bolt between the thrust plates 17. Each thrust element consists of an end plate 18, to which additional lateral strips 19 are welded and the horizontal strips 20 that unite them are attached side slats and extending in length and width beyond their dimensions. In the stop element, the end plates are designed for the perception of horizontal tensile forces arising in the releases of the working reinforcement.

Additional side rails are designed for sensing and transmitting the same forces from the bolt reinforcement releases to the connecting rods of the column. Horizontal strips are designed for the perception of bending forces arising in the face and additional side slats, and provide the rigidity of the element,

Horizontal and additional side bars on one side and connecting rods with plates on the other hand are stops for vertical clamps 12. End plates of the stop element and fixings 3 columns are stops for horizontal clamps 11. Vertical clamps perceive the tensile forces arising in the upper zone of the frame node.

Horizontal retainers perceive possible compressive forces. In the metal sheets, cutouts 21 can be made in the middle part. In this case, at the cutout point, the lower fixings 22 protruding beyond its lower plane and entering into the cutouts of sheets are fixed at the ends of the crossbars. Lower fixtures are designed for the perception of compressive effort

Mount the junction as follows.

The girders 1 are mounted on the cantilevers formed by the side 13 and the support 14 bars. In the gaps between the stop plates of the 15 side plates and the fixings of the 16 bolts, additional vertical locks 17 are inserted, resting them from the bottom into the support bars 14. Between the plates 9 connecting rods 8 and additional side bars 19 of the stop elements 7 insert vertical locks 12, abutting them below the horizontal bars 20 of the stop elements. Horizontal clamps 11 are inserted between the connecting rods, abutting them on one side into the end strips of the thrust element, and on the other hand in the embedded parts 3 of the column 2.

At the installation, the column is supplied with metal consoles in the lower zone and with connecting rods having plates 9. After the bolts are installed in the design position, the joint ends of the connecting rods cover with clamps 10, which eliminates the bending of their ends and plates outwards, Clamps can have at the ends of the ring bends, which are worn on the connecting rods. Mounting bolts are supplied with 6 stop elements 7 fixed on the releases of the working reinforcement.

After calibrating the design position of the transoms relative to the column, the gaps between the transoms and the column and the cut part of the transom ridge and the lateral faces of the column are ground with concrete (not shown).

The proposed technical solution allows quickly with minimum labor costs and with low metal consumption to create a reliable, high load bearing capacity, welded coupling of the elements of the building framework and the structure.
