As shown in fig. 1-5, the prefabricated assembly 100 of the sports field floor 10 according to one embodiment of the present invention is a laminate structure including a rigid lower layer 102 and an elastic upper layer 104.

The prefabricated assembly 100 includes a body portion 120 and four tenon portions 140 connected to the body portion 120. Two of the tenon portions 140 are located on one side of the main body portion 120, and the other two tenon portions 140 are located on the opposite side. The two tenon portions 140 located on the same side of the main body portion 120 and the main body portion 120 together enclose a fastening groove 160, that is, the prefabricated assembly 100 is recessed on two opposite sides to form a first fastening groove 161 and a second fastening groove 162.

Any cross section of the prefabricated assembly 100 perpendicular to the stacking direction has an i-shape formed by recessing opposite sides of a parallelogram. On the plane of any cross section, four figures which are respectively on the same side with the four tenon parts 140 and are in central symmetry with the corresponding tenon parts 140 form the parallelogram together with the cross section. It will be appreciated that the common edge of each tenon portion 140 and the corresponding depicted figure in cross-section is the edge of the tenon portion 140 that serves as the wall of the snap-in groove 160.

As shown in fig. 4, the graph s1 is located at the same side of the first tenon portion 141, and the graph s1 is located at the center of symmetry of the first tenon portion 141, the center of symmetry being the midpoint of the common side; the graph s2 is located at the same side of the second tenon portion 142, and the graph s2 is located at the center of symmetry of the second tenon portion 142, the center of symmetry being the midpoint of the common side; the graph s3 is located at the same side of the third tenon 143, and the graph s3 is located at the center of symmetry with the third tenon 143, the center of symmetry being the midpoint of the common side; the graph s4 is coterminous with the fourth tenon portion 144, and the graph s4 is centrosymmetric with the fourth tenon portion 144, and the symmetry center is the midpoint of the coterminous side; the patterns s1 and s2 correspond to the patterns constituting the first card slot 161, and the patterns s3 and s4 correspond to the patterns constituting the second card slot 162; the pattern s1, the pattern s2, the pattern s3, and the pattern s4 together with the cross section constitute the parallelogram. Each clamping groove 160 can be embedded and matched with one tenon part 140 of the other two prefabricated assembling parts 100, and a plurality of prefabricated assembling parts 100 with the same size can be tightly spliced to form the gapless sports field ground 10.

From the groove bottom to the notch of each engaging groove 160, the distance between the groove walls on the corresponding two tenon portions 140 has a stage of decreasing, that is, the groove walls on the corresponding two tenon portions 140 have a stage of approaching each other. Thus, on-site construction only needs to lay a plurality of prefabricated assembling pieces 100 on the foundation according to the drawing, and the adjacent prefabricated assembling pieces 100 can be naturally clamped through the clamping grooves 160 and the tenons 140, so that dislocation among the prefabricated assembling pieces 100 is prevented.

In one example, the elastic face layer 104 completely covers the rigid base layer 102, and the edge of the elastic face layer 104 protrudes 1mm to 2mm beyond the edge of the rigid base layer 102. Through the design, when paving, the mutual extrusion butt in edge between the elastic surface layer 104 of adjacent prefabricated built-up part 100, connect between the adjacent prefabricated built-up part 100 inseparabler, the marginal gap can't see basically, has also avoided the card to go into the foreign matter and has damaged the condition of elastic surface layer 104.

In one example, an adhesive layer 106 is disposed between the rigid lower layer 102 and the elastic upper layer 104, and the rigid lower layer 102 and the elastic upper layer 104 are fixedly connected by the adhesive layer 106. The bonding manufacture process is completed in a factory, the prefabricated assembly part 100 is transported to the site to be directly paved, bonding construction on the paving site is not needed, and the problem that the construction period is often prolonged in a rainy and continuous weather environment due to the fact that an adhesive which cannot be stained with water is needed during installation and construction in the past, and the construction process is greatly influenced by weather can be solved. The prefabricated assembly member 100 can be paved in all weather, and the paving construction efficiency is high.

In one example, the distance between the groove walls on the respective two tenon portions 140 gradually decreases from the groove bottom to the notch of each of the snap grooves 160. In the specific example shown in fig. 3, each of the catching grooves 160 is a trapezoidal groove.

In one example, the rigid bottom layer 102 is a laminate of one or more of a wood-plastic composite layer, a metal layer, and a reinforced concrete layer (a reinforced concrete-embedded layer). The massive rigid bottom layer 102 serves as a foundation in the conventional sense and provides sufficient support for the resilient surface layer 104 to stabilize the playing surface 10 against shifting.

In one example, the elastic surface layer 104 is a rubber layer, such as a polyurethane rubber layer, and has good physical motion performance, including more excellent impact absorption, slip resistance coefficient, and the like, so as to completely meet the requirements of various professional sports, and has good weather resistance and long service life.

The surface of the elastic surface layer 104 may be roughened, such as to form a fine concave-convex structure, to form anti-slip lines, etc., to prevent people from slipping during movement.

In one example, the rigid substrate 102 has a thickness of 6mm to 20 mm. In some specific examples, the thickness of the rigid bottom layer 102 is 8mm, 10mm, 13mm, 16mm, 18 mm.

In one example, the elastic facing 104 has a thickness of 10mm to 50 mm. In some specific examples, the thickness of the elastic facing 104 is 20mm, 25mm, 30mm, 35mm, 40 mm.

Further, in one example, the parallelogram is rectangular.

In the specific example shown in fig. 3, the parallelogram is square.

In one example, the sides of the parallelogram are 40cm to 100cm in length.

In the specific example shown in fig. 3, any cross section of the prefabricated assembly 100 is a central symmetry figure, and the symmetry center is the geometric center of the parallelogram. In this example, each tenon portion 140 is a right trapezoid, connected to the main body portion 120 by its shorter base.

In the specific example shown in fig. 6, the side length a1 of the parallelogram (square) is 40cm, the width b1 of the bottom of the catching groove 160 is 30cm, the width c1 of the notch is 10cm, the depth d1 of the catching groove 160 is 10cm, and the acute angle α 1 of each tenon portion 140 is 45 °.

In the specific example shown in fig. 7, the side length a2 of the parallelogram (square) is 40cm, the width b2 of the bottom of the catching groove 160 is 26.7cm, the width c2 of the notch is 13.3cm, the depth d2 of the catching groove 160 is 11.5cm, and the acute angle α 2 of each tenon portion 140 is 60 °.
