Abstract

This invention relates to a framework m. Of multi-storey buildings. The aim of the invention is to reduce the material intensity of the frame with an increase in the number of flat slabs. In the frame formed by the columns and slabs, monolithic arches are installed along the axes of the columns and diagonally of the cells formed by the columns. The arches are interconnected by the supporting parts and with the floor plates by the supporting parts and the upper part. The overlap GTlites are equipped with additional reinforcement located on the columns of the columns and diagonally in the cells. Columns and inventory columns are installed, a non-opening package is made at ground level. they are lifted and fastened to the columns and inventory columns at the design elevations, monolithic arches are made, they are rigidly connected to the floor slabs and between themselves, and after the concrete has been installed, the inventory columns are dismantled. 13 il.

Description

The invention relates to the construction, in particular to the large-span frameworks of multi-storey buildings and methods of its formation, and can be used in buildings erected by the method of lifting.

The aim of the invention is to reduce the material intensity of the frame with an increase in the spans of non-beam slabs.

FIG. 1 shows the frame of a multistory building, fragment; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 — node II in FIG. 2; in fig. 5 is a section BB in FIG. four; in fig. b - node III in FIG. 2; in fig. 7 is a section bb of FIG. 6; in fig. 8 - section G-Y in FIG. 7; in fig. 9 - ceiling plate with additional reinforcement, fragment; in fig. 10 - frame in the stage of production of floor slabs; in fig. 11 - the same, in the stage of lifting the floor slabs and fixing them on the design elevations to the framework columns and inventory columns; in fig. 12 - the same, in the stage of making monolithic arches at the moment of concrete arches having the required strength (inventory columns perceive the corresponding part of the floor load); in fig. 13 - the same, after dismantling the inventory columns.

The skeleton of a multistory building includes columns 1, forming cells 2 of the frame, floor slabs 3, supported on columns 1 and monolithic arches 4 and 5, installed along the axes of the columns 1 and diagonally of the cell cells 2 and rigidly attached to the floor slabs 3 6 and 7 supporting parts. The supporting parts of 7 adjacent arches 4 and 5 are interconnected. Floor slabs 3 are equipped with additional reinforcement 8, placed along the projections of arches 4 and 5 in plan and perceiving thrust.

The floor slabs 3 perform the role of tightening for arches 4 and 5 located on them.

The framework of a multistory building has the lowest consumption of materials, since

The installation of arches 4 and 5 makes it possible to additionally support floor slabs 3 within each cell 2. In addition, the interfacing of arches 4 and 5 with flat girders creates a spatial system capable of receiving horizontal loads.

The skeleton of a high-rise building is erected in the following sequence.

Install the frame columns 1, forming cells 2 and inventory columns 9 height to the full height of the frame, make a package of 10 floor slabs 3 at ground level with placing additional reinforcement 8 along the axis of columns 1 and diagonally cells 2 to accommodate expansion, floor slabs 3 are lifted and fastened to columns 1 and 9 at design elevations, then monolithic arches 4 and 5 are made along the axis of columns 1 and diagonally of the cell 2 cells 2 with their fastening to floor slabs 3 and among themselves, after a set of concrete arches 4 and 5 necessary According to the arcs 4 and 5, the loads from the overlying slabs 3 dismantle the inventory columns 9. The lifting of the slabs 3 is carried out by means of lifts 11 mounted on columns 1 and 9.
