Examples

As shown in fig. 1 to 4, the splicing structure of the sports flooring glue of the embodiment comprises a flooring glue sheet 1 and an elastic connecting member 2; the number of the ground films 1 is at least two and the ground films are spliced adjacently; the elastic connector 2 comprises a ground rubber connector 201 and a base surface connector 202 which are overlapped along the thickness direction of the ground rubber sheet (indicated by a double-headed arrow in the figure); the ground glue connector 201 and the base surface connector 202 are detachably connected through a connecting part which is matched with each other in a concave-convex manner along the thickness direction of the ground glue film; the bottom surface of the ground rubber sheet 1 is provided with a concave part 101 for accommodating the elastic connecting piece 2, the ground rubber connecting piece 201 is fixedly arranged in the concave part 101, and the base surface connecting piece 202 is provided with a base surface abutting surface.

It will be appreciated that the ground glue connector 201 and the base connector 202 have overlapping surfaces opposite in the thickness direction of the ground glue film, the overlapping surfaces being provided with mating projections b and mating recesses a that mate with each other in a concave-convex manner. The butt joint protrusions b are all arranged on the ground glue connector 201 or the base surface connector 202; or part of the butting protrusion b is arranged on the ground glue connector 201, and part of the butting protrusion b is arranged on the base surface connector 202.

The overlapping surfaces of the ground glue connector 201 and the base surface connector 202 are preferably horizontal surfaces; the material is selected from silica gel or plastic elastomer, preferably silica gel, and besides excellent rebound resilience performance, the ground rubber connecting piece and the base surface connecting piece of silica gel also have higher friction force, and furthermore, the material of the elastic connecting piece is consistent with the elasticity of the foaming bottom layer thickness direction and the horizontal direction of the ground rubber sheet 1.

The recess may optionally extend through the ground glue connector 201 and/or the base connector 202, or may be non-through.

The orthographic projection of the ground rubber connector 201 and the base surface connector 202 along the thickness direction of the ground rubber sheet completely coincides, or coincides only at the edge of the ground rubber sheet 1, but does not coincide at the first side opposite to the splicing side of the ground rubber sheet 1, for example, the elastic connector 2 of the concave-convex fit connection is in a step shape at the first side, and the base surface connector 202 protrudes from the ground rubber connector 201. Correspondingly, the concave part 101 is also a corresponding step-shaped concave. Compared with the orthographic projection superposition of the ground rubber connecting piece 201 and the base surface connecting piece 202, the base surface connecting piece 202 protrudes out of the ground rubber connecting piece 201, and is beneficial to forming a horizontal elastic transition structure from the ground rubber elastic bottom layer to the semi-ground rubber elastic bottom layer and the semi-elastic connecting piece 2 and then to the full-elastic connecting piece 2, wherein the elastic transition direction is shown by an arrow in a broken line frame in fig. 8.

On the square continuous horizontal plane of the ground film 1, the orthographic projection of the splicing side surface of the ground film 1, the splicing side surface of the ground film connecting piece 201 and the splicing side surface of the base surface connecting piece 202 is straight or rectangular. Taking straight orthographic projection as an example, orthographic projections of the spliced side surfaces of the ground film 1 and the spliced side surfaces of the ground film connecting piece 201 coincide; orthographic projection of the spliced side of the ground glue connector 201 and the spliced side of the base surface connector 202 includes the following two modes:

the front projection of the splicing side surface of the first ground glue connector 201 coincides with the front projection of the splicing side surface of the base surface connector 202 (as shown in fig. 5);

the second, ground glue connector 201 is partially or completely misaligned with the orthographic projection of the base connector 202, as shown in fig. 9, where the orthographic projection lines of the ground glue connector 201 and the base connector 202 are parallel to each other.

The ground glue connection 201 has a first surface opposite to the lamination surface and a side surface extending in the thickness direction. Alternatively, the ground glue connector 201 is fixedly connected, e.g. glued, to the concave bottom surface of the ground glue film 1 only by the first surface; the side surface of the ground rubber connector 201 may be fixedly connected with the ground rubber thickness direction side surface of the recess 101 in addition to the first surface.

The base connector 202 has a base engaging surface opposite the laminating surface, the base surface being generally planar, the base connector 202 being raised from the base surface so that the base connector 202 is connected to the base surface only by the base engaging surface.

The butt joint protrusion b and the butt joint recess a of the overlapping surface can be selected from one or more than two of dot, strip, continuous net and the like. In particular, the strip-shaped mating recess a includes, but is not limited to, extending along the mating edge, or extending from the mating edge to the center of the ground film 1, i.e., in any direction intersecting the mating edge, such as a direction perpendicular to the mating edge.

The depth of the recess 101 along the thickness direction of the ground film is specifically determined according to the thickness of the elastic connecting piece 2 overlapped in the unstressed state.

The recess 101 of the individual film 1 is provided at a distance from the splicing edge, for example, the recess 101 is a through groove shape (as shown in fig. 7) having both ends penetrating through the film thickness direction side surface, but spaced from the splicing edge thickness side surface, or the recess 101 is a groove body having at most one end penetrating through the film thickness direction side surface. The through groove shape is more favorable for forming a concave-convex connection structure consistent with the extension length of the splicing edge, ensures that all sections of the splicing edge of the ground rubber sheet 1 are effectively connected, and avoids the problem of local arch caused by the influence of the friction force of the soles of athletes. The greater the spacing of the recess 101 from the mating edge, the more likely it is for the recess to warp or arch at the mating edge.

In another preferred embodiment, as shown in fig. 5, the recess 101 extends along adjacent spliced edges of the ground film 1. Compared with the arrangement of the concave parts 101 and the splicing edges at intervals, the connecting positions of the thickness direction of the ground film are closer to the splicing edges, so that the flatness of the splicing edges in the laying and using processes is improved, the warping or arching probability of the splicing edges is reduced, and the seamless splicing state of the ground film 1 is realized and maintained.

In another preferred embodiment, shown in fig. 5-6, 8-9, the floor mat 1 comprises from the surface to the bottom a plastic layer 102 and an elastic bottom layer 103, the recess 101 being provided at least in the elastic bottom layer 103.

The shaping of the plastic layer is relative to the elasticity of the elastic bottom layer, it being understood that the plastic layer is less elastic than the elastic bottom layer.

Alternatively, the recess 101 is only disposed on the elastic bottom layer 103, which includes two ways:

firstly, the depth of the recess 101 is equal to the thickness of the elastic bottom layer 103, i.e. a stacked structure of the plastic layer 102 and the ground rubber connector 201 is formed in the thickness direction of the ground rubber sheet (as shown in fig. 8);

secondly, the thickness of the elastic bottom layer 103 is larger than the concave depth of the concave part 101, namely, the stacked structure of the plastic layer 102, the thinned elastic bottom layer 103 and the ground glue connecting piece 201 is formed in the thickness direction of the ground glue sheet (as shown in fig. 5-6). The interface between the elastic bottom layer 103 and the elastic ground rubber connecting piece 201 is sheared under the influence of the friction force of the sole, so that the predetermined service life of the bonding structure of the elastic bottom layer 103 and the ground rubber connecting piece 201 is not guaranteed.

The recess 101 is formed by foam molding with a predetermined mold, or is formed by drawing out an elastic bottom layer 103 on the bottom surface of the continuous ground film 1 web based on the existing ground film continuous production. When the elastic bottom layer 103 is a foaming layer, the operation of removing the foaming closed hole structure of the elastic bottom layer 103 is inevitably damaged, the damaged foaming closed hole collapses after long-term use, the thickness of the stacked structure of the plastic layer 102, the thinned elastic bottom layer 103 and the ground rubber connecting piece 201 is reduced, and then the stacked position of the ground rubber top surface elastic connecting piece 2 is recessed, so that the normal service life of the ground rubber is influenced, and the foot feeling is flattened.

The depth of the concave part 101 is equal to the thickness of the elastic bottom layer 103, the problem of destroying the closed pore structure of the foaming layer is avoided, the horizontal stress of the plastic layer 102 directly acts on the elastic connecting piece 2, the elastic connecting piece 2 deforms or is transferred to the adjacent elastic bottom layer 103, and the service life of the ground glue splicing structure is longer. The interface between the plastic layer 102 and the elastic bottom layer 103 is obvious, the constructor can clearly distinguish that the elastic bottom layer 103 can be completely removed from the plastic layer 102 by adopting auxiliary means such as solvent dissolution and the like, and the construction consistency of completely removing the elastic bottom layer 103 is higher compared with the process of thinning the foamed elastic bottom layer 103.

The plastic layer 102 is usually made of plastic solid material, and in the structure of the conventional ground rubber sheet 1, the plastic layer 102 comprises a wear-resistant anti-slip surface layer and a stabilizing layer. The wear-resistant and anti-skid surface layer and the stabilizing layer can be single-layer or multi-layer composite structure, and further, the stabilizing layer is provided with layered components such as fiber mesh cloth with better dimensional stability.

In some embodiments, the orthographic projections of the mating recess a and the mating projection b along the thickness direction of the ground film are spaced apart from each other and uniformly distributed.

When the orthographic projection of the connecting part is dot-shaped or strip-shaped, the intervals of the dot-shaped orthographic projection or the strip-shaped orthographic projection tend to be equal; when the connecting part is orthographic projected into a net shape, the line pitches constituting the net tend to be equal.

In another preferred embodiment, as shown in fig. 1-2, the butt-joint concave a and the butt-joint convex b are arranged in at least one row with the straight extending direction of the splicing edge of the ground film 1 as the row direction.

The distances between the connecting pieces arranged in rows and the splicing edges are equal, and the stress of the connecting portions on the splicing edges tends to be consistent, so that the splicing structure of the ground film 1 is stable and the ground film is reliable in long-time use.

In another preferred embodiment, as shown in fig. 1-2, the connection portions are arranged in at least two rows, with the mating recesses a and mating projections b of adjacent rows being offset. The horizontal acting force exerted by the adjacent-row connecting parts on the dispersible film 1 further reduces the probability of local arching of the splicing edge at the distance between the two connecting parts compared with the single-row connecting parts.

In another preferred embodiment, as shown in fig. 3-4, the connection portion includes a mating recess a that is necked-in and a mating protrusion b that is either a clearance fit or an interference fit with the mating recess a.

In the figure, the convergent butt joint concave a is formed by combining a cylinder and a sphere, and the diameter of the sphere is larger than that of the bottom surface of the cylinder. In the thickness direction of the ground glue film, the butting concave a limits the detachment of the butting convex b, so that an operator can press and connect the ground glue connector 201 and the base surface connector 202 along the splicing sheet in sequence when the ground glue is paved.

The elastic connection member 2 may optionally have local elasticity in the thickness direction of the ground film and in the tetragonal horizontal plane of the ground film 1. In some embodiments, the ground glue connector 201 and the base connector 202 are the same elastic material. The thickness of the ground rubber connecting piece 201 and the base surface connecting piece 202 is equal to that of the elastic bottom layer 103 of the ground rubber sheet 1 after the ground rubber connecting piece and the base surface connecting piece are in butt joint, so that the consideration of rebound fit between different elastic materials is avoided.

The ground with ground glue in the embodiment comprises a base surface 3 and the splicing structure of the moving ground glue in the embodiment, wherein the base surface binding surface is fixedly connected with the base surface 3.

The base surface 3 is typically selected to be the ground, the top surface of a platform, etc.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
