Description

Flooring Flooring Flooring {A borad for floor}

The present invention relates to a floorboard flooring material, and more particularly, to improve the dimensional instability due to heat and moisture, and excellent workability because there is no need to apply a separate adhesive to the concrete floor or install a separate subsidiary material at the time of construction On the floor flooring for flooring construction, which provides excellent convenience in reducing noise by providing sound absorbency and sound insulation as well as providing a lot of convenience, cost and time saving effect even when dismantled for partial repair or reconstruction. It is about.

Conventionally, the method of constructing floorboard after directly applying the adhesive, ie, two-component epoxy and urethane adhesive on the concrete floor, and floating type, that is, PP (polypropylene) having moisture blocking function on the concrete floor. ) Or PE (polyethylene) sheet on the floor to be installed, and then a second PE (polyethylene) foam to give the floor smoothness and cushioning, and then to form a floor Many attempts have been made to overcome the method of applying a vinyl acetate adhesive between the tongue and groove formed on the side of each parquet plate for bonding.

According to Korean Patent Registration No. 394968 (floor finishing flooring material comprising ondol) disclosed by the present inventors, in the floor finishing flooring material manufactured by using a unit disc, the side insert portion at one end in the longitudinal direction And a side accommodating part is formed at one end of the other side; An end receiving portion is formed at the other end and an end inserting portion at one end in the longitudinal direction; Synthetic rubber-based hot melt adhesive is applied to the back side, and is formed by attaching a release paper on the adhesive; When the construction is coupled to the side receiving portion formed in the adjacent floorboard material pre-installed at the same time, the end projection provided at one end is coupled to the end recess groove provided in the adjacent finishing plate material pre-constructed Disclosed is a floor finishing floorboard comprising an ondol for which a hot melt adhesive adhered to a back surface is simultaneously bonded to a bottom surface. However, the cited invention is not only difficult to install smoothly when combined with the side down projections of the side inserting portion of the side receiving groove side down grooves, but also the obtuse projection shape at the end insertion portion and the end receiving portion binding portion There was a problem that the close coupling of the distal end projection and the distal end groove is impossible. In addition, the physical properties of the hot-melt adhesive mentioned in the cited invention is not sound-absorbing and restoring force is complete, and this is pointed out as a problem of noise during walking.

The present invention is devised to solve the problems of the prior art as described above,

The purpose of the present invention is to manufacture a plywood, solid wood, high density fiber board or high-density fiber board (Particle board) on the base plate is manufactured using a disc, HPM or LPM attached to the base plate, considering the thermal properties A synthetic rubber or polypropylene-based hot melt adhesive improved to be suitable for attaching to the back surface of the floorboard material, and a release paper for maintaining adhesive performance thereon is attached, and specially shaped inserts on both sides and both ends of the longitudinal direction, respectively. And the receiving portion is formed, can be installed between the floorboards and floorboards without the use of additional adhesive, and can be used at the same time as the construction does not cause odor caused by the adhesive, and stable dimensional change between floorboards and floorboards To improve the dimensional stability, which is the fundamental disadvantage of wood, To provide ease of reconstruction, and to provide a flooring flooring material comprising an ondol for advantageous sound reduction according to the material features having sound insulation and sound absorption.
