Description

The invention relates to the field of construction and repair of panel residential buildings, and in particular to methods for sealing and insulating joints between panels.

A known method of sealing the joints of building elements, including the treatment of abutting surfaces with an organosilicon composition, filling the joint cavity with a polymer cement mixture, as well as applying a hydrophobizing organosilicon composition to the resulting surface after curing the polymer cement mixture (copyright certificate SU No. 1331974). In the known solution, the organosilicon composition is prepared on the basis of a solvent and applied by a spray gun or a brush both to the abutting surfaces beforehand and to the surface after the polymer of the cement composition has been cured. To fill the joint, a polymer cement mixture is used, in which a latex emulsion is used as a polymer binder.

The disadvantage of this method is that the resulting seams do not have sufficient durability in conditions of increased vibration, with relative vibrations of wall panels, and the known technology of repair and restoration is time-consuming and does not allow for repairs in the cold period.

A known method of repairing interpanel seams and creating protection for wall structures, a method for sealing interpanel seams and creating protection for wall structures, as well as a unit for sealing a seam of an interpanel joint of a wall (RF patent No. 2226234). This method is used to fill the seams with polyurethane foam, which has increased vibration resistance. On one side of the wall, after polymerization with polyurethane foam, a polyurethane foam composition is applied over the mastic strips by spraying over the entire surface of the two-component polyurethane mastic panels adjacent to the seam. On the other side of the wall, an organosilicon composition is applied over its entire surface after polymerization with polyurethane foam.

However, in the known method, there are not enough measures for sealing and insulating the interpanel seam with polyurethane foam, which does not have the above advantages.

Known design for sealing and warming interpanel seams (RF patent No. 2686216). According to this design, there are layers of insulating and adhesive materials for sealing and insulating interpanel seams. The structure is fastened to the wall using disc fasteners with thermal heads for thermal insulation. The disadvantage of this design is the complexity of applying adhesive and other layers, as well as the lack of a description of the method of its manufacture in operations.

A known method of repairing and sealing interpanel seams, as well as a unit for sealing a seam of an interpanel joint of a wall (RF patent No. 2242571).

According to the known method, considered as a prototype, the unit for sealing the seam of the interpanel joint of the wall contains mating panels installed with a gap. The surfaces of the corner chips and the panels themselves are treated with latex mortar. Chipped volumes are filled with non-shrinking cement mortar. At the ends of the panels, layers of a non-shrinking cement mortar are applied, prepared using a latex additive, into which polypropylene fibers are introduced. The gap (expansion gap) of the polyurethane foam can be sealed with a rubber seal (cord). The seam is covered with a strip of elastic sealing coating, which is covered with a sealing tape. An elastic sealing coating is applied to the surface of the sealing tape or across the entire surface of the panels, and a layer of a refractory protective composition is applied to the entire surface of the panel.

However, this method does not provide insulation of interpanel seams and is very laborious in performing operations in the autumn-winter period. Peeling of the applied coatings is also possible due to the lack of mechanical fasteners. The operation of inserting the cord into the joint and its complexity are not described.

The proposed method of sealing and insulating (Figures 1-4) of the interpanel gap (joint) 1 includes operations for installing insulation 2 (for example, a mineral board, penoplex, foam or any similar material), which is superimposed on the interpanel joint 1 and is attached to panels 3 with disc dowels 4 (or similar anchors) with a pitch from 100 to 1000 mm.

If panel 3 has an uneven surface, it is necessary to apply a leveling preliminary adhesive solution 5 to it for a tighter adhesion of insulation 2 to panels 3.

After fixing the insulation, an adhesive solution 6 with a thickness of 2-3 mm is applied to it, then a reinforcing nylon or other mesh 7. Another layer of adhesive solution is applied to the mesh 7. The mesh prevents the layers of adhesive solutions from cracking, thereby increasing their strength. For the design of the facade of a house (building), a paint layer 9 is applied over a layer of adhesive solution 8, or a decorative adhesive layer 10 is applied over a layer of adhesive solution 8 (for example, from a mixture of "bark beetle"). The thickness of the insulation 2 is sufficient from 30 to 100 mm.

Variants of the shape of the section of the interpanel seam are presented in the following figures: trapezoidal - in Fig. 1, rectangular - in Fig. 2, semicircular - in Fig. 3 with the same position numbering.

To simplify the manufacturing method, mechanical strength and waterproofing, the insulation 2 is closed with a galvanized metal painted profile 11 with rubber seals 12 in a U-shaped section, installed at the ends and edges of profile 11. Profile 11 is fixed to panels 3 with anchors 4 with rubber seals 13. Sections the interpanel seam is made of the required length on the ground (indoors or under a canopy) and is fixed at the junction of the panels with an overlap or butt in any weather.

FIG. 4 shows an interpanel seam with a galvanized metal painted trapezoidal profile in section. Similarly, seams of rectangular and semicircular section shapes are made.
