(54) MULTILAYER FLOOR SHIELD

I

The invention relates to construction and can be widely used in the construction of floors of residential and public buildings.

The multilayered structure of the floor panel is known, comprising a face layer of parquet attached to a slab of hard material, for example hardboard, a middle layer made in the form of a frame filled with a reinforced insulating elastic material, and a bottom layer of solid fibreboard or hardboard fl | g

The disadvantages of this design are the complexity and laboriousness of manufacturing, the scarcity and high cost of the facial parquet layer, low operational parameters (swells is when the humidity changes, wear out quickly). In addition, during operation, the middle layer is crushed and loses some of its heat and sound insulation properties.

Closest to the proposed technical essence is a multilayered floor shield, including the front layer, the middle layer of wood and the bottom layer of rubber, laid on the base 2J.

The disadvantages of the known shield are its high cost and limited scope.

The purpose of the invention is to increase durability, wear resistance, moisture resistance and reduce the cost of a sheath, as well as increase the sound insulation of the sheath from impact noise when it is placed on an unlined base.

The goal is achieved by the fact that in a multilayered floor shield, which includes the face layer, the middle layer of wood and the bottom layer of rubber, laid on the base, the middle layer is provided with an NC framing of a polyvinyl chloride film, with a pair of its adjacent ends provided with protrusions the ends are hollows corresponding to the configuration of the protrusions, with the front layer made of PVC film, and the middle layer is made of chipboard.

In addition, the lower layer with storuny facing the base, made with evenly spaced cone-shaped protrusions.

Claims (2)

FIG. 1 shows the floor pint, in plan, of FIG. 2-section AA on fng. 1. The floor panel contains the face layer 1, the middle layer 2, the bottom layer 3, the end bezel 4 with the recess 5 and the protrusions 6. The face layer is made of 0.3-0.4 mm thick PVC film, for which the top finishing layer of two-layer is used. polyvinylchloride linoleum extrusion, produced by the industry according to the VNIstroypolymer formulation. The middle layer 2 is made of durable waterproof chipboard. for example, brand PTP-3-OF. The bottom layer 3 is made of regenerated rubber mixture, consisting of crumb rubber, regenerated cord waste with the addition of styrene rubber butodiene and. vulcanizing agents; The technology of making complex plates is carried out in two variants in the following way. Option 1. The molds in assembled form are preheated to 40-45 ° C, and then opened for laying semi-finished products. On the bottom plate of the form with strips of the team frame, forming the edging of the ends, are placed alternately: granules of 2-3 colors PVC, powdered or pasty composition of PVC, chipboard (chipboard) plate and a layer of plastic from rubber regenerate. This "layered cake is covered with a plate and under pressure of 8-10 atm (with pressing) heated to a temperature of 150-160 ° C, which is necessary for the transition to a plastic state of polyvinyl chloride and rubber regenerate. After 10 minutes at this temperature, the mold is cooled and opened to remove the finished product. Option 2. The mold is 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 background PVC 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 - chipboard. Then put on top a layer of plastic from the rubber regenerate, cover the molding plate and heated to 150-160 ° C. Through the corner holes from two opposite corners of the shape, a liquid PVC composition in the calculated volume is injected into the cavity between the chipboard and the side slats using a syringe. After that, the pressure is Lb-10 atm (with pressing) and after 10 minutes at this temperature, the mold is cooled and opened to extract the finished product. Finished products are placed directly along bearing acoustically homogeneous reinforced concrete interfloor solid slabs with a thickness of 140-160 mm dry. The use of the proposed shield provides a reduction in labor costs at the construction site as compared to laying linoleum (the cheapest floor at the present time) by no less than 25%, reducing the time required for flooring by eliminating labor-intensive operations to install industrial lightweight concrete or more labor-intensive. wet processes for laying monolithic light concrete paving under linoleum or parquet, effective rational waste disposal (chipboard based on wood processing waste, insulation of impact noise on Nove recycling and recovery of used rubber tires) and a lower cost floor construction. Claim 1. A multi-layered floor shield comprising a face layer, a middle layer of wood and a bottom layer of rubber laid on a base, characterized in that, in order to increase durability, wear resistance, moisture impermeability and cost reduction of the shield, the middle layer is provided with a polyvinyl chloride frame film, ari this pair of its adjacent ends is provided with protrusions, and in a pair of other adjacent ends are made depressions corresponding to. configuration protrusions, and the front layer is made of PVC film, and the middle layer is made of particle board. f 2. Shield on and. 1, due to the fact that, in order to increase the sound insulation of a shield from impact noise when it is placed on an unaligned basement, its lower layer from the side facing the base is made with evenly spaced cones, shaped protrusions.
