Description
COMPOSITE SURFACE FLOORING PANEL
This invention relates generally to flooring materials for architectural structures and more par-ticularly to a surface flooring material of compositepanel form to be laid especially on concrete base floors, which material can be laid directly on the rough surface of concrete slabs to form an excellent floor surface, and which material absorbs sound, has a high soundproofing effect, has an excellent tread feel for people walking thereon, is readily installed, and provides safe floors on concrete base in places such as gymnasiums where ~igorous physical. acti~i-ties, sometimes accompanied by falling and tumbling of participants, are conducted.
Concrete is the building material of choice in many structures requiring strength and is indispens-able in the construction of medium to large buildings because of its strength, particularly when used in con-junction with steel materials, durability, availabilityand low price, fireproofness and heat resistance, facility in use, and many other desirable character-istics. On the other hand, concrete buildings re~uire surface finishing particularly on their interior sur-faces and more particularly on the upper surfaces oftheir floors, which cannot be economically finished with concrete forms as in the case of wall and ceiling . ..

surfaces.
In many instances concrete floors are surface finished directly with various cement mortars and mixtures such as terrazzo. Such floors are hard and unyielding. Some floors are covered with synthe-tic resin tiles and ceramic tiles, but these ordinarily require leveling of the rough concrete with mortar.
Another important class of building materials in the architectural and building construction field is that of composite boards and panels of various types, which have and are being widely used~ The most common among the known panel products are those comprising, in composite form, upper and lower sheathing sheets or boards in mutually spaced-apart relation and a sound-absorbing material such as glass wool or-roc~
wool packed therebetween with the object of obt~; ni ng sound-absorbing and soundproofing effect.
When a conventional panel material of this type ~0 is used as a flooring mat~rial, the panel material it-self has insufficient sound-absorbin~ and soundproofing effect and, moreover, does not have a cushioning property. For these reasons, the tread feel of the resulting fIoor is poor, and the panel material exhibits practically no effectiveness in reducing the trans-mission to the floor below reverberation of noise and vibration caused by dropped or overturned objects, 7~2~
jumping and running of people, yelling and scream-ing of small children, and other causes.
Particularly when such a panel material is used as a flooring material for a concrete floor, joists or sleepers are ordinarily first laid over the concrete floor~ and then the panel material are laid thereon and secured thereto by nailing. This prac-tice is not only entails high installation cost but also reduces the room space since the final floor level is raised considerably above the concrete floor level. Direct laying of conventional panel material on a concrete floor surface is accompanied by the difficulty of direct bonding with an adhesive due to some unevenness of the rough concrete surface.
In view of the problems as described above in the prior art, it is an object of this invention to provide a composite flooring panel material which can be laid directly on a concrete base floor to form a floor surface structure having the desirable character-istics of excellent tread feel, high sound-absorbing and soundproofing effectiveness, ease of installation, and safety with respect to falls, these character-istics being afforded without considerable raising of the finished 100r level.
According to this invention, briefly summarized, there is provided a composite surface flooring panel comprising a surface board material and an elastic lZ07~
ribbing bonded to the lower surface of the surface board material and being in the form of a corrugated plate with a cross-sectional profile consti-tuted by alternating upright and inverted trapezoidal wave forms comprising horizontal upper flat ridges and lower flat ridges disposed in alternate disposition respectively on upper and lower sides of the ribbing and integrally joined by we~s alternately inclined in opposite directions, the upper flat ridges being bond-ed to the lower surface of the surface board material, the lower flat ridges being bondable to a base floor.

upper and lower surfaces of the ribbing except the outer fLat faces of the flat ridges, are preferably covered with a nap or pile of fibers 11 implanted electrostatically in the surfaces as densely as possible. The length of the exposed parts o~
these fibers 11 is of the order of 1 to 3 millimeters. By implan~ing these fibers 11 in this mAnn~r~ -the sound absor~ing and insulating effect is increased and the propagation of vibration and noise to the floor below is effectively prevented.
As the Eibers 11, natural fibers such as wool, silk or cotton, synthetic fibers such as fibers of nylQn, vinylon or Tetoron (Trademark of Torai Kabushiki Kaisha, Japan) or acrylic synthetic fibers, or semi-synthetic fibers such as viscose rayon or acetate rayon can be used.

~Z07~2~
Another advantageous feature of a flooring struct~re made up of the panels 1 according to this invention is that, because of thè interposition of the elastic ribbings 3 with the air layer as described above between the sur-face board material 2 and the concrete L loor, moisture from the concrete floor surface 7 is completely prevented from infiltra.ing upward to the board material 2. Further-more, since the elastic ribbing 3 is made of an elastic ma-terial such as rubber, it is subject to almost no permanent de~ormation with passage of time, whereby the planari~y of - the flat floor surface can be maintained over a long time.
Still ano~her fea~ure of the panel of this invention is that its cons.ruction lends itself readily to standardiza-tion of its dimensions, whereby ~artial replacement or parts at the time o repairs is facilitated.
When it is necessary to increase the cushioning pro-perty OI tne rloor, an assembly thereof wherein two layers of the elastic ribbing 3 are used in superposed arranyement as shown in FIG. 5 can be used. In this case, the direc-tions of the ribs 10, 10 respectively of the two layers of the elastic ribbings 3, 3 may be at right angles to each other or may be parallel to each other. When the direc-tions of the ribs 10 of the upper and lower ribbings 3 are parallel, these ribbings should be so disposed relative to each other as shown in FIG. 6 that the upwardly directed _g_ ~. ~
~37~2~ -furrows of the lower ribbing 3 confront the downwardly directed furrows of the upper ribbing 3, respectively, whereby parallel elongated spaces are formed. Prefera-bly heat insulating material 12 such as glass wool is filled in each elongated space.
Because of the character of the panel according to this invention as described above, a floor can be readily laid directly on a concrete slab floor without the use of underlying material such as joists or leveling mortar, whereby the floor installation work can be carried out rapidly and at low cost.
Furthermore, by filling -the empty spaces formed in the elastic ribbing 3 with a soundproofing and thermally insulating material such as a synthetic resin insulation material, glass wool, or rock wool, the soundproofing, im-pact absorbing, and heat insulating properties of the panel of this invention can be improved even further. This re-sult is also attained when two layers of the elastic rib-bing 3 are used. The filling of the empty spaces of the ribbing 3 with the above mentioned material can be facili-tat~d by cutting the material finely to suit the empty spaces.
Because of the mechanically cushioning characteristic of the panel of this invention, it can be advantageously used for constructing safe and strong floors particularly for places where vigorous activities take place. Examples of such places are gymnasiums and training halls for sports such as judo, aikido, karate, kung-fu, and boxing.
