Description

The invention relates to the field of construction, in particular to the field of construction of multi-storey residential and public buildings from precast concrete.

The structure of a multi-storey building, consisting of prefabricated flat panels of vertical walls, on which flat floor panels with embedded parts are supported on both sides, and on which, in turn, the vertical wall panels of the upper floor are supported, forming a “platform” joint with an anchor in the concrete body of the walls coming out with a nut from the upper end of the wall panel, passing between the floor slabs, panels of the outer walls, in which the wall panels for transportation and for installation by a crane are vertically equipped with loops made of bent reinforcing bar steel, located on the upper end of the panels and in the body of concrete, to capture the traverse hooks,

the difference lies in the fact that adjacent floor panels are interconnected by a patch welded to their embedded parts of the floor with a hole through which an anchor with an expanded flat top passes, emerging from the upper end of the wall.

In addition, the anchor is welded to the plate around the hole.

The structures of large-panel buildings are widely known, consisting of prefabricated flat panels of vertical walls, on which flat floor panels with embedded parts are supported on both sides, and on which, in turn, the vertical wall panels of the upper floor are supported, forming a "platform" joint (1, 2). There are solutions when the joint is provided with an anchor with a nut in the concrete body of the walls (2 p. 73). The anchor emerges from the upper end of the wall panel and passes between the floor slabs. Wall panels, in addition, for transportation and for installation by a crane, are equipped with loops made of bent reinforcing bar steel, located at the upper end of the panels and in the body of concrete, to capture the traverse hooks. Most often, floor slabs based on one wall panel are welded to each other by welding loop outlets to each other and using embedded parts with the panel itself. The "platform" joint can be converted to combine the functions of lifting wall panels and the operation of the joint itself.

The disadvantage of this design is that the metal hinges of the wall panels made of reinforcing steel significantly increase the consumption of metal during the construction of buildings. After installation, the metal of the hinges is practically not used in the construction.

The closest technical solution in relation to the claimed solution is the design of a large-panel building, for example, presented on page 73 (2), which shows the joint of vertical wall panels with floor slabs resting on them using anchors that serve to fix wall panels at the desired level.

The aim of the invention is to create a structure of multi-storey buildings with prefabricated floor panels and walls without hinges.

The essence of the invention is that adjacent floor panels are interconnected by a plate welded to their embedded parts of the floor with a hole through which an anchor with an expanded flat top passes, emerging from the upper end of the wall.

In addition, the anchor is welded to the plate around the hole.

The essence of the invention is disclosed in the drawings, which show:

in fig. 1 is a general view of flat wall panels with floor slabs resting on them,

in fig. 2 - general view of the wall panel with outlets used to lift products and subsequent connection with floor slabs,

in fig. 3 - joints at the junction between floor slabs in plan,

in fig. 4 - a fragment of the connection at the junction between the floor slabs in the plan,

in fig. 5 - general view of a fragment of the connection at the junction between the floor slabs in the plan,

in fig. 6 - cross section of the "platform" joint.

Prefabricated structures of a multi-storey building are subject to transportation for installation. Basically, these are vertical walls and floor slabs 1 (Fig. 1). Usually, prefabricated elements are lifted and lowered for transportation and installation by crane equipment using special traverses with a grip on metal loops made of reinforcing steel, which are anchored in the concrete body of the panels, but in the present building design, the loops are replaced by reinforcing outlets from the wall panel.

Prefabricated vertical flat panels 1 of walls and ceilings 2 (Fig. 1) form a "platform" joint 3. The vertical wall panels 1 themselves at the upper end have outlets 4 with an expanded flat top 10 (Fig. 2), and in the body of concrete at the ends they may have, for example, welded plates for better anchoring. Mounting loops 5 with internal grooves for the expanded anchor 10 are put on the flat upper part 10, rotated 90 degrees. Mounting loops 5 are used to move the panels during demoulding, transportation and installation.

The connection of floors 2 with each other supported by walls 1 is shown in plan in Fig. 3. Plates 2 along their length at the location of the anchor outlets 4 on the surface in the recesses 6 have embedded parts 7 (Fig. 3). Mortgages 7 (Fig. 4) of adjacent plates are interconnected by a steel plate 8 with a hole 9 through which the anchor 4 passes. Anchor 4 is connected by welding 11 to the plate 8 around the hole 9. General view of the connection node of the anchor issue 4 at the level of floors 2 to the plates 8 is shown in FIG. 5. It is also shown here that in the recess 6 the plate 8 is welded to the embedded parts 7 of the floor panels 2. In FIG. 6 shows a cross section of such a connection, where the anchor 4 enters the groove 10 of the top panel 1.

In the manufacture of vertical reinforced concrete wall panels 1 (Fig. 1), anchors 4 are installed (Fig. 2). At the top, the anchor is expanded by compressing it in a press. After the heat treatment of the concrete, on the expanded top 10 of the anchor 4, lifting loops 5 are put on and rotated 90 degrees (Fig. 2) and the product is transported to the warehouse, then to the panel carrier and then mounted using a traverse. After mounting the panel 1, the hinges 5 turn in the opposite direction and disconnect from the anchor 4. Next, the floor slabs 2 (Fig. 3) are mounted by installing them on the upper end of the wall panel 1. Embedded parts 7 located in the recesses 6 (Fig. 4) of the floor slabs 2 adjacent panels are connected by welding overlays 8 with the hole 9 of FIG. 5), which are strung on the anchor. The anchor 4 is welded to the lining around the hole 9 and then the wall panel of the next floor is installed through the underlying layer 12 (Fig. 6).

Thus, this makes it possible to dispense with reinforcing steel loops anchored in the concrete body of the panels, which leads to significant savings in reinforcing steel.

The proposed technical solution allows not only transporting and mounting panels without hinges, but also lifting them from cassettes during vertical molding. With horizontal molding of flat prefabricated elements, such a solution is also possible.
