Description

[Detailed Description of the Invention] In recent years, noise-related regulations have become stricter regarding the floors, walls, etc. of wooden general houses or apartment complexes, and structural members that have vibration-proofing and sound-insulating effects, especially for wooden houses, and their Construction methods are in demand.

Conventionally, the floor structure material for general wooden houses or apartment complexes has been wooden frames, or in the case of concrete slabs, the floor has been finished by laying linoleum, jutan, cork, etc. directly on the concrete slab to prevent solid-borne sound. Alternatively, solid-borne sound was prevented by laying impact reinforcement material such as glass wool over a concrete slab to create a floating floor structure.

In general wooden houses, the flooring material is placed on the wooden joists, and if necessary, a vibration-proofing sheet, such as linoleum, jutan, cork, etc., is laid on top of it to provide vibration-proofing treatment. Solid-state transmission sound was prevented.

However, in a typical wooden house, this method has little vibration-proofing effect because the entire floor is not a floating floor.

Since the anti-vibration floor structure material is not made into panels, it takes a considerable amount of time to create the anti-vibration floor structure, making construction inefficient.

In the case of nailing construction, the floor must be fixed above the joists above the surface of the subfloor material, but impact noise is transmitted to the joists through the nails, reducing the anti-vibration effect.

There were problems such as.

The present invention has been made to solve these problems, and is intended to provide a method for constructing a floor panel that uses a vibration-isolating rubber sheet and has a desired vibration-isolating effect. Its composition is
An anti-vibration rubber sheet is attached to the entire lower surface of a rectangular floor base material with grooves for grooves formed around the sides around the interior walls, and the lower surface of the anti-vibration rubber sheet. After pasting the anti-vibration rubber sheet with the same or slightly larger thickness as the three-layer anti-vibration floor panel to which the backing board is attached to form a nailing allowance, the anti-vibration rubber sheet is attached. Inject the adhesive while fitting the yatoite pieces into the recessed grooves for yatoite processing provided on the vibration-proofing floor panel, and sequentially insert the yatoite floor panel from one side of the wall or from the center of the room. Tighten so that they are close together,
The present invention relates to a method of constructing a vibration-proofing floor panel in which nails are fixed from the nailing allowance onto joists arranged at substantially the same intervals as the width of the vibration-proofing floor panel.

To explain the present invention in more detail based on the drawings, FIG. 1 is a perspective view showing a floor panel used in an embodiment of the present invention.

The lower surface of the floor base material 1, such as plywood, particle board, hardboard, etc., with Yatoji 10 processing applied around the sides, and the back board 3 cut to the same size as the base material.
A vibration-proof rubber sheet 4 is adhered between the upper surfaces of the two with an adhesive 2 interposed therebetween.

At the time of pasting, the positions of the backing board 3 and the floor base material 1 are shifted from each other so as to leave a nailing allowance 12. This is because even if the floor panel is constructed by driving 9 nails onto the joists 8 provided on the wooden base 7, the nails 9 can be completely separated from the floor base material 1 by the four layers of vibration-proofing rubber sheets.

In addition, around the side of the floor base material 1,
The reason for performing the processing is to facilitate the construction of the floor panel, and also to completely join the joints of the floor base materials 1 to prevent squeaks that may occur when the base materials 1 rub against each other.

As an example of construction of a vibration-proof floor panel having the above configuration, as shown in FIG. A vibration-proof rubber sheet 6 of slightly larger size is pasted. Next, a Yatoi piece 13 is attached to the Yatoi piece 10 provided on the floor panel.
Then, while injecting adhesive 11, tighten the walls 5 so that they are close to each other from one side of the wall 5 or the center of the room, and fix by driving 9 nails onto the joists 8 from the nailing allowance 12 to complete the floating floor structure. shall be. Note that the joists 8 are fixed in advance on the wooden base 7 at intervals that approximately correspond to the width of the floor panels.

The floor base material 1 used in the present invention has a thickness of 7
Refers to plate-shaped objects such as plywood, particle board, hardboard, etc. that are approximately 25 mm to 25 mm.

As the adhesive 2, various room temperature curing adhesives can be used, such as a rubber resin adhesive, an epoxy resin adhesive, and a vinyl acetate resin adhesive.

As the anti-vibration rubber sheet 4, a rubber sheet having an anti-vibration effect such as vulcanized rubber, unvulcanized rubber, vulcanized rubber mixed with iron powder particles, or vulcanized rubber mixed with lead powder particles is specified.

As the Yatoi piece 13, an elongated piece of plywood, a piece of plastic, or the like is used.

As the backing board 3 which becomes the nailing allowance 12, thin plywood, hardboard, synthetic resin board, etc. can be used.

When the floor panel according to the present invention is constructed by the above-mentioned construction method, the floor base material 1 is formed by the anti-vibration rubber sheet 4.
Since it is completely separated from the indoor wall surface 5 and the joists 8, the entire floor can be made into a floating floor structure.

Since the floor is made of panels, construction can be done easily and efficiently by nailing.

Since the anti-vibration rubber sheet is sandwiched between the floor panels, the impact resistance of the floor panels is increased, and the heat insulation and moisture resistance are improved.

Effects such as this can be achieved.

Next, a construction example that is an embodiment of the present invention will be described.

Example: After forming grooves for actual machining with a width of 7 mm and a depth of 10 mm in the floor base material of a rectangular particulate board with a thickness of 20 mm, ethylene-
After applying 250 g/m ² of a vinyl acetate copolymer resin adhesive evenly over one surface, a 1 mm thick unvulcanized rubber sheet for vibration isolation was placed on the adhesive-coated surface of the floor base material. Next, under the same conditions as the base material, 2.7 mm thick plywood coated with an ethylene-vinyl acetate copolymer resin adhesive on the upper surface was placed one on top of the other so that the adhesive coated surface was in contact with the unvulcanized rubber sheet. When placing the plywood, two of the four circumferences of the plywood were placed offset by 20 mm each with respect to the subflooring material.

This composition was compressed for 20 hours and with a clamping pressure of 10 kg/
When constructing a three-layer anti-vibration floor panel obtained by cold-pressing at ^cm3 onto the joists formed on a wooden foundation,
First, the thickness is 1 1 around the interior wall surface that touches the floor panel.
A vibration-proof rubber sheet with a height of 24 mm was attached. Next, the end face of each floor panel is pressed against the indoor wall surface on which the anti-vibration rubber sheet has been pasted. At the same time, the edge of each floor panel is 40 cm from the 20 mm wide nailing distance provided on the plywood part that makes up the floor panel.
They were fixed by nailing onto the wooden joists at intervals. During construction, an epoxy resin adhesive was injected into the flooring material by fitting a long thin plywood piece with a thickness of 5 mm and a width of 20 mm into the grooved grooves for processing the yato material. With this method, the floor base material and the plywood fixed on the joists are completely separated by the anti-vibration rubber sheet layer, making it possible to create a floating floor structure with anti-vibration effects.
