Abstract

FRAME OF MULTILEVEL BUILDING OR CONSTRUCTIONS, including columns with consoles, crossbars of variable sectional height, rigidly connected to the columns and between themselves, floor plates supported on the crossbars and rigidly attached to them, and flying plates, characterized in that with the aim of increasing stiffness, reduction of material consumption and labor-intensiveness of installation, the nacelle plates are cut but the axes of the frame and are combined with span plates, the latter being connected to the bolts with a flexible one. sl 00 ate

Description

The invention relates to the construction and can be used in the construction of frames of multi-storey buildings and structures. The purpose of the invention is to increase the gesture: the bones, reducing the consumption of materials and the complexity of the installation. FIG. 1 shows the frame of a multistory building or structure in plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. 4 — node I in FIG. one; in fig. 5 shows a section B-B in FIG. four; in fig. 6 - section G-Y in FIG. four; in fig. 7 is a section d-d in fig. four; in fig. 8, section EE of FIG. 4. The framework of a multistory building or structure includes columns 1 with consoles 2, crossbars 3 of variable cross section in height, rigidly connected to the columns I and between themselves, floor plates 4 supported on crossbars 3 and rigidly attached to them, and span plates 5. Nadol plates 4 are cut along the axes of the carcass and combined with span plates 5. Span plates 5 are connected with ribs 3 elastically compliant. Columns 1 can be made multi-storey. It is possible to use typical columns of a crossbar frame. During installation, girders 3 are connected to columns 1 with plates of reinforcing bars 6 or strip steel. Between them, bolts 3 are joined by welding reinforcement outlets 7. After that, the joints of the crossbars 3 between themselves and with the columns 1 are carefully embedded with concrete 8, which together with the extended outlets 7 and reinforcing bars 6 provides the rigidity of the joint. The crossbars 3 at the columns 1 have a trimming, on the console 9 of which the span plates 5 are supported. Each of the span plates 5 is joined along the ends with portions of the column plates 4 cut across the span. Span plates 5 are connected to ribs 3 in the lower zone by welding of the plates 10, and in the upper zone by rebar 11 or strip plates. After connecting the assembly elements, the joint is carefully filled with concrete 12. In the central part of the slab, where the crossbar 3 and the span plate 5 are the same, concrete keys 13 are located along their lateral longitudinal edges, which provide the transmission of shear vertical forces. The overlap in the frame system works like a multi-span slab. With pillars 1, this plate forms a spatial frame whose girders are girders (plates of the transverse direction and tufts 14 of girders 3 and span plates 5 in the longitudinal direction. Span plates 5 work as a plate clamped on the nuts 14 of beams 3 with which it is connected by rigidly connecting the inserts or by welding the reinforcement and the elastoopert on the crossbars 3 in the middle of the rolled metal, where it is connected to the crossbars 3 by pins 12. transmitting shear forces. they are interconnected by welding the fixings with reinforcing rods 15. located at the ends.To increase the rigidity of the frame in the longitudinal direction, reducing the consumption of metal in the seams between the span plates 5, prestressed reinforcement may be laid along the plot of moments, t. that is, in the upper zone on the supports and in the lower zone - in the spans (not shown).
