Example 1

Referring to fig. 1 to 2, the present embodiment discloses a composite floor 100, wherein the composite floor 100 includes a plastic panel 110, a metal supporting layer 120 and elastic supporting legs 130, and has a multi-layer composite structure, so as to improve adaptability to a variable environment, and ensure mechanical properties and a service life.

The plastic panel 110 covers the metal supporting layer 120, and is an appearance surface and a contact surface of the composite floor 100. The plastic panel 110 is made of plastic material, and has the excellent characteristics of plastic material, such as good impact resistance and buffering property, less impact when a sporter moves and bounces thereon, better bounce assisting force, and the smooth completion of the movement while protecting the body safety.

The plastic panel 110 can be an integral structure formed by integral injection molding, and the surface flatness is more ideal; the plastic panel 110 may also adopt a split-type splicing structure, which is easy to splice and install and greatly reduces the processing difficulty.

Exemplarily, the plastic panel 110 includes a plurality of splice plates, and the splice plates are respectively disposed on the metal carrier layer 120 to form a splice surface. It can be understood that the plurality of splice plates have a fit clearance therebetween, so as to avoid collision interference and surface bulging damage caused by thermal expansion and cold contraction, and ensure that the outer surface of the composite floor 100 is smooth.

The metal bearing layer 120 is made of a metal material and is a structural bearing layer of the composite floor 100 for bearing the moving impact transmitted downward from the plastic panel 110 and providing structural support to the plastic panel 110. The metal bearing layer 120 may be made of different metal materials, such as steel material, aluminum profile or other alloy materials.

Meanwhile, the application of the metal bearing layer 120 can effectively reduce the thickness of the plastic panel 110, overcome the defect of poor dimensional stability of the plastic panel 110 under temperature rise based on the lower temperature rise deformation of the metal bearing layer 120, ensure the dimensional stability and the structural safety of the composite floor 100 under severe temperature change, and particularly adapt to outdoor application environments.

The plastic panel 110 and the metal supporting layer 120 may be formed by composite molding (e.g., plastic-clad steel injection molding), or may be fixed and connected by mounting and connecting structures (e.g., pin joint, screw joint, clamping joint, etc.) after being formed respectively.

The plastic panel 110 and the metal bearing layer 120 are fixed by a mounting connection structure. The plastic panel 110 has a panel end splicing portion 111, and the panel end splicing portion 111 is formed on a side surface of the plastic panel 110 close to the metal carrying layer 120. Correspondingly, the metal carrier layer 120 has a first carrier side splicing part 121, and the first carrier side splicing part 121 is located on one side surface of the metal carrier layer 120 close to the plastic panel 110.

The panel end splicing part 111 and the first bearing side splicing part 121 are connected in a jogged manner, so that the plastic panel 110 and the metal bearing layer 120 are tightly connected to form a reliable integral structure. In other words, one of the panel end splicing portion 111 and the first carrier side splicing portion 121 is embedded in the other. After the plastic panel 110 is fitted in place, the lower surface of the plastic panel is in fit connection with the upper surface of the metal bearing layer 120, so that a sufficient connection area is ensured and reliable stability is achieved.

Exemplarily, the panel end splicing portion 111 is a splicing strip protruding from the lower surface of the plastic panel 110, and the first bearing side splicing portion 121 is a splicing groove penetrating through the metal bearing layer 120 along the horizontal direction. The splicing strips are embedded into the splicing grooves, so that the splicing strips and the splicing grooves are connected in an embedded mode.

The metal carrier layer 120 may be of a hollow structure, a solid structure, or the like, for different applications. The metal bearing layer 120 may be implemented in various structures including bracket, truss, plate, etc. types. Illustratively, the metal bearing layer 120 has a bracket plate structure with better mechanical properties and lower self weight.

The first carrier-side splicing portion 121 can be processed by different processing methods. For example, the first carrier-side splicing portion 121 may be formed on the surface of the metal carrier layer 120 by a material-removing forming process (including mechanical cutting, laser cutting, wire cutting, electrical discharge cutting, and the like); as another example, the first carrier side splice 121 can be integrally formed (e.g., cast, additive manufactured, etc.) on the metal carrier layer 120; for another example, the first carrier-side joint portion 121 may be formed on the metal carrier layer 120 by bending in a sheet metal working manner.

The elastic support legs 130 are supported on a side of the metal supporting layer 120 away from the plastic panel 110 for elastically connecting the composite floor 100 with the ground. The elastic support legs 130 are made of an elastic material, such as rubber, silica gel, etc., and can absorb impact kinetic energy to have a buffering effect, so as to avoid the possibility of rigid impact when the metal bearing layer 120 directly contacts with the ground, so that a sporter can comfortably and safely bounce, and the structural integrity between the composite floor 100 and the ground is ensured.

The elastic support legs 130 have a support leg structure, and form a supporting structure with the metal carrier layer 120. The upper end of the elastic support leg 130 is embedded in the metal carrier layer 120, and the lower surface thereof protrudes below the metal carrier layer 120.

Exemplarily, the plurality of elastic support legs 130 are plural, and the plurality of elastic support legs 130 are arranged in an array on a side of the metal carrier layer 120 away from the plastic panel 110 (e.g., a lower surface of the metal carrier layer 120), so as to form a multi-point distributed support structure.

The metal bearing layer 120 and the elastic support legs 130 may be formed by composite molding (e.g., plastic-clad steel injection molding), or may be fixedly connected by mounting connection structures (e.g., pin joint, screw joint, clamping joint, etc.) after being formed respectively.

The metal bearing layer 120 and the elastic legs 130 are exemplarily fixed by a mounting connection structure. Wherein, the metal carrier layer 120 has a second carrier side splicing portion 122, and the second carrier side splicing portion 122 is located on one side surface of the metal carrier layer 120 close to the elastic leg 130 (for example, the lower surface of the metal carrier layer 120). Accordingly, the resilient leg 130 has a leg end splicing portion 132, and the leg end splicing portion 132 is formed at an end of the resilient leg 130 close to the metal bearing layer 120 (e.g., an upper end of the resilient leg 130).

The second bearing side splicing part 122 is connected with the leg end splicing part 132 in a jogged manner, so that the metal bearing layer 120 is tightly connected with the elastic legs 130 to form a reliable supporting structure. In other words, one of the second load side splicing portion 122 and the leg end splicing portion 132 is embedded in the other. After the metal bearing layer 120 is embedded in place, the upper surface of the metal bearing layer is in fit connection with the upper surface of the lower end of the elastic support leg 130, so that a sufficient connection area is ensured and reliable stability is achieved.

The second carrier side splice 122 can be machined in different ways. For example, the second carrier-side splice 122 may be formed on the surface of the metal carrier layer 120 by a material-removing forming process (including mechanical cutting, laser cutting, wire cutting, electrical discharge cutting, etc.); as another example, the second carrier side splice 122 can be integrally formed (e.g., cast, additive manufactured, etc.) on the metal carrier layer 120; for another example, the second carrier-side joint portion 122 may be formed on the metal carrier layer 120 by bending in a sheet metal working manner.

The resilient legs 130 may be implemented using a variety of leg structures. Illustratively, the resilient legs 130 have a T-shaped configuration. The T-shaped configuration has a support pad 131 for snug attachment to the ground, and a leg end splice 132 extends upwardly from the upper surface of the support pad 131. Exemplarily, the leg end splicing part 132 has a hollow ring-shaped configuration, further reduces the self weight while ensuring the structural strength, saves the manufacturing material and reduces the cost.

Exemplarily, a side surface of the support plate 131 away from the leg end splicing part 132 has a plurality of anti-slip protrusions 133. The plurality of anti-slip protrusions 133 are distributed in an array to increase the frictional damping between the support mat 131 and the ground, thereby preventing the composite floor 100 from being positionally displaced. Meanwhile, the plurality of anti-slip protrusions 133 also serve as a distributed support. The anti-slip protrusions 133 may be implemented in various structures, including a protruding strip, a protruding point, and the like.

Exemplarily, the outer circumference side of the metal bearing layer 120 has a lateral joint for splicing with the metal bearing layer 120 of the adjoining composite floor panel 100. In other words, the composite floor 100 can be further spliced to form a sports floor, thereby reducing the processing cost, the transportation cost and the installation difficulty of the sports floor.

Further, the lateral joint portions are a first lateral joint portion 123 and a second lateral joint portion 124, which are located on different sides of the same metal carrier layer 120. The first lateral joint 123 of the metal bearing layer 120 is tightly joined with the second lateral joint 124 of the adjacent composite floor panel 100, achieving a reliable continuous splice.

The first lateral joint 123 and the second lateral joint 124 can be spliced in different ways, for example by means of a pin joint, a threaded joint, a snap joint, etc. Exemplarily, one of the first lateral connecting portion 123 and the second lateral connecting portion 124 is a male end, and the other is a female end, which are engaged with each other to realize a tight splicing.

The male and female ends may be implemented in various forms, such as various stud and groove configurations. Exemplarily, the first lateral engaging portion 123 is an engaging hook protruding out of the side surface of the metal carrier layer 120, and the second lateral engaging portion 124 is a hooking groove recessed into the side surface of the metal carrier layer 120, and the engaging hook is embedded into the hooking groove to achieve hooking.

Referring to fig. 1-4, a specific splicing application of the composite floor 100 is described. According to the requirement of a required sports field, the composite floor 100 is sequentially and continuously spliced to form a flat sports floor, so that the manufacturing, transporting and installing difficulties are reduced. Wherein the splicing structure is realized by the aforementioned splicing structure of the metal bearing layer 120.

It should be added that, when the composite floor boards 100 are sequentially spliced, a fit gap is formed between the plastic panels 110 of adjacent composite floor boards 100, so as to avoid surface bulging and even structural collision damage caused by temperature rise deformation of the plastic panels 110, and ensure the smoothness and structural safety of the sports ground.

In all examples shown and described herein, any particular value should be construed as merely exemplary, and not as a limitation, and thus other examples of example embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

The above-described embodiments are merely illustrative of several embodiments of the present invention, which are described in detail and specific, but not intended to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
