CZ26316U1 - Wood concrete coupled floor construction provided with flooring assembly - Google Patents

Description

Furthermore, this construction can be used in civic amenities buildings where there is an increased demand for noise resistance and also allows for the improvement of other building features (structural statics, fire safety, heat and cold storage). The construction according to this application can also be used in the construction of wooden buildings.

For the purposes of this application, a wooden part means, for example, a wooden beam, a concrete part such as a reinforced concrete slab and a reinforcing element such as a steel-curling net, a connecting element eg a pressed dark board. tiles, linoleum, acoustic insulation for the purposes of this application are cardboard boards filled with quartz sand.

Clarification of drawings

The technical solution is explained by means of the drawings, in which Fig. 1 is a sectional view of the ceiling structure. Giant. 2 shows the structure of the ceiling structure shown in Example 2 when the wear layer has changed. Giant. 3 then illustrates the composition of the ceiling structure according to Example 3, where the soffit and thermal insulation are added. Giant. 4 shows the course of the airborne sound insulation values on the measured structures and FIG. 5 shows the course of the sound insulation values on the measured structures.

Examples of implementation

Example 1

The wood-concrete composite ceiling structure provided with floor construction (according to Fig. 1) consists of wooden KVH beams and profile 80 x 140 mm „rigidly“ connected to reinforced concrete slab 2 of 60 mm thickness made of C 20/25 XO concrete reinforced with KARI steel 100/100 / 5. On the reinforced concrete slab 2, a leveling (separating) layer of 10 mm thick fibreboard 3 with a thickness of 2 mm is laid all over the meeting area in two layers. Another layer is acoustic insulation 4 made of cardboard filled with quartz sand at a thickness of 15 mm. A floating floor 5 is used as the surface wear layer.

Example 2

Wood composite composite ceiling structure provided with floor construction (according to Fig. 2) consists of wooden KVH beams I of profile 80 x 140 mm, “rigidly” connected with reinforced concrete slab 2 thickness 60 mm. On the reinforced concrete slab 2, a leveling (separating) layer of 10 mm thick fibreboard 3 is applied in two layers. Another layer consists of acoustic insulation 4 made of cardboard filled with quartz sand at a thickness of 15 mm. On this layer, a penetration layer 7 with a 3 mm thick lining is laid in a flexible adhesive. The next layer is then a 2 mm thick adhesive 8 applied over the entire surface area. Attached to the wooden KVH beam 1 is a panel 6 of 80 x 60 x 2 mm with embossed darkness, which improves the rigidity of the individual layers of the structure. Ceramic tiles 9 are then used as the surface wear layer.

Example 3

The wooden composite ceiling structure provided with floor construction (according to Fig. 3) consists of wooden KVH beams and profile 80 x 140 mm, “rigidly” connected with reinforced concrete slab 2 of 60 mm thickness. On the reinforced concrete slab 2, a leveling (separating) layer of 10 mm thick fibreboard 3 is applied in two layers. Another layer consists of acoustic insulation 4 made of cardboard filled with quartz sand at a thickness of 15 mm. A floating laminate floor 5 is then used as a surface wear layer. On the wooden KVH beam 1, a panel 6 of 80 x 60 x 2 mm with embossed darkness is fastened in the production. In the lower part of the wooden KVH beam is installed thermal insulation 11 so that a closed air gap 12 with a total thickness of 60 mm is formed between it and the reinforced concrete slab 2. Thermal insulation 1T is loosely laid on plasterboard ceiling 10 with a thickness of 15 mm, which closes the construction from the bottom side
