Description

(3) JOINT CONNECTION OF WALL PANELS AND COVERINGS

one

 The invention relates to a builder, a design, namely, prefabricated housing construction, mainly for dry installation of panel walls and floors in houses installed in harsh climatic conditions.

There is a known joint of panels of walls and overlappings in a large-panel building in the form of a platform joint in which the wall is supported on the lower panel through the supporting parts of adjacent panels of the ceiling LlJ.

With this joint design, technological and assembly tolerances lead to a difference in the thickness of the overlap panels and to the formation of a variable thickness of the mortar seam across the width of the support part, which complicates the installation and causes an uneven distribution of stresses in the end of the upper panel, reducing the static operation of the joint and reducing it strength.

In addition, the disadvantage of this joint is the need to perform wet processes associated with filling the joints with cement mortar during installation, which, when erecting buildings at low temperatures, reduces the bearing capacity of the joints, significantly increases the cost of construction and reduces installation rates.

The closest to the invention with the technical essence and the achieved result is a butt joint of wall panels and rear cover plates, including protrusions in the support part of the slab of the overlap, which it is supported on the end of the bottom wall panel through a gasket of elastic-plastic material, grooves in the end face of wall panel and placeholder

20 stitches 2.

A disadvantage of the known joint design is the impossibility of ensuring reliable protrusion of the projections of the floor slabs half the thickness of the wall panel, which requires minimum installation tolerances, which reduces the processability of the installation, and the protrusions of the floor slabs (simultaneously on two opposite ends) when foaming 8 cassettes - The lead is the manufacture of these projections and in the upper level at the open side of the cassette, which is not technological. The aim of the invention is to improve the manufacturability and manufacturing. The goal is achieved by the fact that in the butt joint of wall panels and floor plates, including protrusions in the base part of the floor plate, it is supported on the end of the bottom wall panel through a pad of elastic plastic material. , the transverse grooves in the end of the upper wall panel and the filler of the i-seams, the end of the upper panel is supported on one of the floor slabs, laid) on the lower wall panel across the entire width of its end, and Lit overlap are located in the corresponding grooves of another slab. In addition to the togg, a transverse groove, made in the upper wall panel, ramestens above the protrusions. The protrusions of one of the floor slabs are made in the form of vertical end loop-shaped reinforcement and are located in the grooves of another plate. The protrusions of one slab are made of a rolling profile, for example, of a corner, and are located in corresponding slots made on the end of the lower wall panel, and the second slab is made with under cutting. FIG. 1 shows a butt joint, axonime, FIG. 2 the same, vertical section; in FIG. 3; the same. Horizontal section; FIG. and 5 is the same, a variant with loopback outlets, respectively, vertical and horizontal cuts, in FIGS. 6 and 7 the same, a variant with outlets from the angle, respectively, longitudinal and transverse vertical cuts. The proposed butt joint includes an upper wall panel 1 supported through a gasket 2 to one of

overlapping plates 3, which are laid through a gasket C on the lower wall panel i and the overlap plate 6, are provided with protrusions 7, which are placed in the slots 8 of the overlap plate 3 and are supported on the lower wall panel 5 The seams between the overlap plates 3 and 6 are filled with slightly bonded material 9, such as sand. Gaskets 2 and 4 are made of an elastic-plastic material, for example, mineral-impregnated mineral wool mats. The protrusions 7 can be made of reinforced concrete (Figs 1-3), | The upper panel 1 is provided in the end part with transverse grooves 10 placed above the protrusions 7 of the plate 6 and filled with a low-strength acoustic insulation material, for example plaster mortar. In another embodiment (Fig. D and D), the protrusions 7 of the plate 6 are made in the form of vertical end loop-shaped reinforcement outlets, forming, for example, a triangular contour of the base to increase the bearing area, inclined to the longitudinal axis of the joint. In the third embodiment (Fig. 6 and), the protrusions 7 of the plate 6 are made in the form of metal outlets of angular section, included in the triangular transverse grooves 14 at the end of the lower panel S, while the slab 3 has a trimming 12 in the support part. In the proposed joint design, the load from the upper floors is transmitted through the upper wall panel 1 to the supporting part of only one overlap 3 and further to the lower wall panel 5, while the grooves 10 at the end of the upper wall panel 1 prevent load transfer from the upper floors to the second slab 6, which passes through the protrusions 7 to the bottom panel 5 a load from only one floor. . The installation of the proposed joint is carried out by laying the slab with protrusions through the gasket over the entire width of the bottom wall panel and then laying the second slab with placing the tabs of the first slab in its grooves and then installing through the gasket of the upper wall panel. The design of the proposed butt joint makes it possible to support each slab over the entire width of the wall panel, which simplifies installation, reduces the requirements for its tolerances and increases the reliability of the joint, while leaning the upper new panel onto only one slab significantly reduces the effect of manufacturing errors. and Mo Tazha, which makes it possible to implement dry installation, Improves its manufacturability and increases the strength of the joint. In addition, the design of the slabs that are included in this butt joint, makes it possible to refuse to form reinforced concrete protrusions in the upper level at the open side of the cassette, replacing it with a more technologically advanced groove or installing metal outlets. invention 1. Butt joint of wall panels and floor slabs, including protrusions in the supporting part of the floor slab, with which it is supported on the end face of the lower wall panel through a gasket of elastic-plastic material, transverse grooves in the end face of the upper wall panel and joint filler, characterized by that, in order to increase the manufacturability and manufacturing, the end of the upper panel is supported on one of the floor slabs laid on the lower wall panel across the entire width of its end, and the protrusions of one of the slabs of laid in the corresponding grooves of another slab. 2. Connection pop. t, characterized in that, in order to eliminate the top wall panel on the protrusions of one of the overlap plates included in the grooves of the other plate, the transverse groove made in the top wall panel is positioned above the protrusions. 3. The connection according to claim 1, characterized in that the protrusions of one of the floor slabs are made in the form of vertical end loop-shaped reinforcement releases and are located in the grooves of the other plate. The distinction in accordance with claim 1, which is distinguished by the fact that the protrusions of one slab are made of. rolling profile, for example from the corner and are located in the corresponding grooves made on the end of the bottom wall panel, and the second slab is made with trimming.
