Description

(54) MULTILAYER FLOOR SHIELD

1. The invention relates to the construction and can be used in the construction of floors of residential and public buildings. The three-layered structure of the floor shield is known, which includes a protective layer made of impregnated wood material, a middle layer of laminated board material and a lower layer consisting of a synthetic thermoplastic material with the formation of closed spherical cavities filled with Cl3 gas. However, this design is costly due to the use of expensive and scarce materials as well as the high labor intensity of manufacturing. The closest to the invention is a multilayered floor shield comprising a face layer of rigid material, a lower SRI layer of elastic material and a tight framing on the end surfaces, while the middle layer is made of particle board, the polyvinyl chloride film framing and the bottom layer of rubber 2 . The disadvantage of this construction is that there is a scarce and expensive rubber raw material for the device of the lower elastic layer. In addition, the design has low performance indicators for heat and sound insulation. The purpose of the invention is to improve the heat and sound insulation properties and reduce the cost of a floor shield. This goal is achieved by the fact that in a multilayered floor panel comprising a face layer, a middle layer of rigid material, a bottom layer of an elastic material and hermetic framing on the end surfaces, the bottom layer is made of a composition comprising the components in the following ratio, wt. %: Refining waste in the production of the regenerator; ta rubber; 56.5-63.5: 15 -17 crushed cord

See Figure 1 shows a schematic multilayer floor shield in plan; in FIG. 2, section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 - Weel P nafig.Z

The shield of the floor contains the face layer 1, the middle layer 2, the bottom layer 3, the end frame 4 with grooves and vanes.

The front layer is made of a polyvinyl chloride film of thickness O, 3-O, 4 mm. The plan of this is using the top finishing layer of a two-layer extrusion PVC linoleum. The middle layer is made of durable, water-resistant workpiece-PLATE, for example, brand PTP-Z-OF. The lower layer is made of a compo- sition obtained from the processing of Ryuzin automotive tires after their use. The middle layer is sealed on the end surfaces with a frame made of polyvinyl chloride paste, i.e., to prevent deformations when the air humidity changes, the middle layer of particle boards is enclosed to a closed volume. For ease of installation, the end surfaces of the pin have each adjacent sides.

As can be seen from the table. 2, the proposed construction of the floor shield from the known one is distinguished by a longer thermal insulation characteristics.

recesses and on the other two sides of the protrusions, and the profile of the protrusions and recesses coincides with their combination. On the outer side, the lower elastic layer has tapered protrusions that are uniformly distributed over the entire plane, and their height is 0.5-0.8 of the thickness of the lower layer for laying on the untreated overlapping surface.

In tab. 1 shows examples of compositions of the lower layer of the floor shield.

Example 1. The molds in assembled form are preheated to 594 ° 4O-45 ° C, and then cleared to lay semi-finished products. On the bottom slab of the fork, we with strips of the modular frame forming the edging of the ends, are placed alternately: granules of 2-3 rivet PVC, chipboard and a layer of rubber-cord composition. This layered cake is covered with a plate and under pressure of 8-1 O atm (with subpressing) is heated to a temperature of 150-16 O necessary for the transition to a plastic state of polyvinyl chloride and a rubber-cord composition. After 10 minutes of exposure at this temperature, the mold is cooled and opened to remove the finished product. Example 2. Press the press also preheated to 40-45 C, and then opened for laying on the bottom plate of a decorative PVC finishing film with a printed pattern (if it is translucent, then a layer of PVC backing lining film). On the film set along the contour of the plank of the team frame, forming the edging of the ends, and at the same time chipboard. Then a layer of a rubber-cord composition is laid on top, covered with a molding plate and heated to 150 -. Through the corner holes from the two opposite corners of the shape, a liquid PVC composition is injected into the cavity between the particle board and the side rails using a syringe into the cavity. After that, a pressure of 8-10 atm is applied (with pressing) and after 10 minutes of exposure at the indicated temperature, the mold is cooled and expanded to remove the finished product. Finished products are laid directly along the carrying acoustically homogeneous reinforced concrete interfloor ceilings of solid section with a thickness of 140 - 16 Ohm dry. The use of the proposed invention in comparison with the known benefits of reducing the labor costs at the construction site compared with laying linoleum (the cheapest pop) by at least 25%, efficient and rational waste utilization (chipboard based on wood waste), heat insulation and isolation of impact noise (based on processing and regeneration of used rubber tires), lower cost of floor installation - according to approximate calculations, floor construction of panels costs 7.88 p / m.
