(54) HARDNESS DIAFRAGM

one

The invention relates to the construction of multi-storey frame buildings and structures.

The stiffness aphragms used in the construction of multi-storey frame buildings for ensuring their overall stability and the perception of the horizontal loads acting on the buildings are known, forming a solid housing panel that, in combination with the columns of the framework, forms a vertical frame element. siste -.

We til The disadvantage of the diaphragms is that, with large spans between the columns (more than 4.5 m), the weight of the diaphragms exceeds 5 tons, which leads to an increase in the capacity of cranes used in Maos construction.

The closest to the invention in terms of technical dryness and the achieved result is the diaphragm of rigidity of a multi-storey frame building, made of a composite width of two hundred NEW panels interconnected and with the columns of the frame, with the help of key vents with fittings and joints on welding of individual embedded parts C2.

The disadvantages of diaphragm are the inability to restore their copebi stiffness, the laborious installation process, and the high consumption of metal for the installation of fixings and reinforcement.

The purpose of the invention is to ensure the ability of the diaphragm to restore its rigidity at the same time, simplify installation and reduce the consumption of metal.

The goal is achieved by the fact that in the diaphragm of rigidity of a multi-storey frame building, made of composite width of two wall panels connected to each other and with frame columns, the panels are made in the form of a rectangular trapezium and coeodential between each other in the sheet pile, and the stiffness diaphragm is provided with monolithic bolts placed between adjacent height panels, the columns and bolts being made with grooves for the panels, and the height is set to the diaphragm height with a variable inclination direction with ykuemyh sides, wherein the panel set up large trapezium base, arranged with a gap relative nizheraspopozhennogo bolt. FIG. 1 shows the diaphragm of the bone, fragment; FIG. 2 is a section A-A in FIG. 1; in fig. 3 shows a section BB in FIG. 1. The stiffness diaphragm of a multistory frame building includes columns l, monolithic bolts and wall panels 3 and 4, which are composite in width. Columns 1 and bolts 2 are made with slots 5 and 6 for mounting panels 3 and 4 in them, and the latter are made in the form of a rectangle trapezoid and are interconnected by inclined sides 7 into the tongue, with panel 3, mounted with a large base of the trapezium on the downstream bolt 2, made with groove 8, and adjacent panel 4 with tongue 9 and mounted with a gap 10 relative to the same bar 2, Pr it m along the height of the stiffness panel 3 and 4 are placed with a variable direction of the joined sides 7. The order of mounting the stiffness diaphragm is as follows. After installing the columns 1 of the frame and checking their vertical position, set the panel 3 so that its vertical side face enters the groove 5 of the column, and the lower base - into the groove 6 of the reinforced concrete 2. Then mount the panel 4, which is lowered by a crane to the design position along the guide grooves 5 and 8 of the column 1 and the panel 3. After the action of the thrust created due to the presence of inclined side faces, panels 3 and 4 for their design position between the lower base of the panel 4 and the monolithic reinforced concrete bolt 2 remains a gap. Next, concreting of the reinforced concrete bolt 2 of the next floor is carried out. D 1 rigidity works barely blown. When vibrations of a building are in operation at the joints, smoothing of the contact surfaces occurs, which causes a decrease in the rigidity of the diaphragm. However, at the same time, due to the presence of the inclined sides 7 and the gap 10, the panel 4 will be lowered under the action of its own weight, occupying a new position relative to the panel 3. At the same time, the frictional forces arising in the joints of panels 3 and 4 of the diaphragm with columns 1 and along the inclined the joined sides 7 are prevented from moving the panels 4 and thereby absorb some of the energy imparted to the building by the source of the vibrations. In addition, the joints will become compacted under the action of the created thrust. Thus, the design stiffness of the diaphragm will be restored by it. The source of oscillations of buildings can be seismic and wind loads, as well as dynamic loads from equipment and others. The use of a monolithic bolt avoids installation difficulties in the presence of deviations in the installation of panels 3 and 4 from the design position and the monolithing of the horizontal joint of the diaphragm panels. The proposed stiffness diaphragm allows you to restore the diaphragm stiffness, simplify installation by enforcing fixing of the panels and minimizing the amount of welding, and also reduce metal consumption by eliminating embedded parts at the joints of the panels with columns and between themselves. Claims The stiffness diaphragm of a multi-storey frame building is made of a composite wall of two wall panels interconnected with frame columns, which is designed to restore rigidity during building fluctuations, simplify installation and reduce the consumption of metal, the panel made in the form of a rectangular trapezoid And are interconnected by inclined sides to the tongue, and the diaphragm of the rigidity is equipped with monolithic bolts placed between adjacent height panels, and columns and girders are made with grooves for the panels, and the latter are set at the height of the diaphragm with a variable direction of inclination of the abutting sides, with the panel. set up with a large base of a trapezoid, are placed with a gap relative to the downstream bolt.
