Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a laminated block structure for wood floors installed on the floor (10). The floor 10 targets concrete slabs of various sports facilities, but is not necessarily limited thereto. In general, a plurality of set bolts 12 are fixed while forming mortar 11 on the bottom 10 of the concrete slab. The laminated block structure of the present invention is located between the mortar (11) and the main floor (15).

According to the present invention, the plywood 20 having the fixing step 23 for fixing the position therein is vertically and horizontally engaged by the upper step 21 and the lower step 22 of the side. The plywood 20 may use a perforated plate and constitute one sheet or two sheets. The material of the plywood 20 can be selected from solid wood, MDF, and particle board, it is also possible to apply the core plywood laminated a variety of materials. In any case, the upper step 21 and the lower step 22 are formed in the form of cutting the middle of the thickness at the four sides. Referring to the plan view of FIG. 2, the upper stepped portion 21 is formed in a concealed state on the bottom of the side portion, while the lower stepped portion 22 is formed in an exposed state on the top surface of the edge portion. In Figure 2, the fixed step 23 is exemplified in the form in which two circular holes of different diameters are drilled concentrically. When the upper step 21 and the lower step 22 of the plywood 20 is brought into contact with each other and is fixed in the fixed step 23 by the set bolt 12 extends in the longitudinal direction, the floor intermediate body is configured. The final floor is completed by attaching the main floor 15 to the upper side of the plywood 20.

At this time, the gap 26 may be formed between the neighboring plywood 20 and the plywood 20 without the upper step 21 and the lower step 22 being in close contact with each other. Floors of athletic facilities are caused by stretching movements due to the effects of moisture contained in wood and the momentary impact of the exercise process. The gaps 26 between the plywoods 20 allow this stretching movement to prevent weakening of durability. The size of the gap 26 depends on the specifications of the plywood 20 but is set to about 5 mm.

Meanwhile, although not shown, a plurality of small gaps may be formed at regular intervals along the gaps 26 between the plywood 20. In addition, the gap 26 may be filled with a material having high elasticity, buffer resistance, and wear resistance.

In addition, according to the present invention, the shock absorbing material 30 is configured to attach at least one of the viscous pad 31 and the linear pad 32 to the bottom surface of the plywood 20 to absorb shocks. The buffer material 30 is formed by mixing waste tire chips and powder as a main raw material by mixing a synthetic resin, rubber, a flow agent, a crosslinking agent, and a compatibility enhancer. In some cases, the thermosetting adhesive may be mixed to increase strength, or the blowing agent may be mixed to form a foam. In FIG. 1, the viscous pad 31 is shown in the form of a small (eg, 30 mm wide) dot, and the linear pad 32 is formed in the form of a bar formed similarly to the width of the plywood 20. In any case, the shock absorbing material 30 is attached to support the sides and the inside of the plywood 20.

As a detailed configuration of the present invention, the shock absorbing material 30 is a projection bump 34 or plywood 20 interposed in the gap 26 of the adjacent plywood 20 of the concave-convex groove 36 in point contact at multiple points It is characterized by having at least one. In FIG. 3, the protrusion jaw 34 formed on the upper surface of the shock absorbing material 30 is attached to the gap 26. Protruding jaw 34 also serves to mitigate the impact transmitted to the neighboring plywood (20). In FIG. 4, the uneven groove 36 formed on the upper surface of the shock absorbing material 30 is attached to the bottom surface of the plywood 20. Concave-convex groove 36 is advantageous to increase the elastic displacement compared to the projection jaw (34).

Of course, it may be configured by combining the protruding jaw 34 and the concave-convex groove 36 with respect to one bottom 10. This includes a method of newly forming by integrating the functions of both in addition to the manner in which the protruding jaw 34 and the concave-convex groove 36 are formed independently.

At this time, it is good to configure the moisture barrier material 28 between the mortar 11 and the plywood 20 of the bottom (10). The moisture barrier 28 may be applied in various forms such as sheets, blocks, paints, and the like. In the case of forming a sheet, the sheet is attached to the mortar 11 or attached to the bottom surface of the plywood 20. In the case of forming a block, amino alkyd resin or the like is used to attach the same height between the buffers 30. In the case of a paint, an ultraviolet curing component (acrylic resin paint, urethane resin paint) is applied and irradiated with ultraviolet rays.

In addition, according to the present invention, the clip 40 is accommodated in the fixing step 23 of the plywood 20 to maintain the position on the bottom 10. The clip 40 is formed in the shape of a cup with a flange 41 on the top using a metal material. The central portion of the clip 40 has a fastening hole 45 for engaging with the set bolt 12. When the clip 40 is coupled to the set bolt 12 in a state in which the clip 40 is accommodated in the fixed step 23, the flange 41 of the clip 40 comes into close contact with the fixed step 23, thereby fixing the position of the plywood 20. do. Of course, the pressing force by the flange 41 of the clip 40 is set differently according to the specifications of the floor. In some cases, the clip 40 may be left in a free state without pressing the fixing step 23.

As a detailed configuration of the present invention, the clip 40 is characterized in that it is formed of a structure for maintaining the fixed step 23 and the variable clearance 43 to allow the stretching movement of the plywood 20. In the enlarged view of FIG. 3, the clearance 43 is formed in the direction of the outer circumferential surface of the flange 41, and the clearance 43 is also formed in the downward direction of the flange 41. The clip 40 is coupled to the free state to allow the three-way flow as well as the stretching motion of the plywood 20. The variable play 43 means a free state as such. If the clip 40 is accommodated in the circular fixed step 23, the coupling direction can be freely changed.

As a variant of the invention, the clip 40 is characterized in that it further comprises a curved table 47 formed in a semi-circular cross section to reduce the vertical deformation on the flange (41). In FIG. 5, the semi-circular cross-sectional structure of the curved stand 47 reduces the contact area with the plywood 20 to ensure smooth stretching and flow of the plywood 20. Curved surface 47 is illustrated in the illustration in a curved shape on the flange 41 of the clip 40, but may be formed in a straight line. In either case, if the curved surface 47 is formed in the flange 41, the rigidity is increased, thereby preventing the durability of the floor. Along with the curved table 47, the above-described protruding jaw 34 of the buffer member 30 also serves to maintain the position of the plywood 20. Position maintenance does not mean a complete fixation but includes a set range of flow.

As a further variant of the invention, the plywood 20 is characterized in that it further comprises an incision groove 25 at least partially to allow the stretching movement in the portion in contact with the clip 40. In FIG. 5 illustrates a cutaway groove 25 across the two flanges 41 of the clip 40. Of course, the cutting groove 25 may be formed in a shorter length around the flange (41). In any case, the structure in which the flange 41 of the clip 40 presses the cutaway groove 25 allows the expansion and movement of the plywood 20.

In operation, the impact acting on the main floor 15 is transmitted to the plywood 20 and the cushioning material 30 when the athlete jumps or falls on the floor of the gymnasium, the elasticity by the plywood 20 and the clip 40 Deformation absorbs shock and prevents breakage. This function is caused by interconnecting the gap 26 of the plywood 20, the play 43 of the clip 40, the cutting groove 25 of the plywood 20 and the like.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
