Description

Technical Field

[0001] This utility model belongs to the field of semi-prefabricated sports field technology, and in particular relates to a seamless semi-prefabricated sports field structure that is easy to splice and position. Background Technology

[0002] Seamless semi-prefabricated court structures typically refer to courts that are prefabricated and assembled on-site, using certain positioning technologies to allow the various parts of the court to be connected efficiently and accurately, forming a stable and usable structure.

[0003] According to a public announcement of a seamless semi-prefabricated sports court (publication number: CN222313702U), the prefabricated sports court body includes a seamless surface layer, a second surface layer, a first surface layer, an interface agent layer, a prefabricated layer, an adhesive layer, a second intermediate layer, a first intermediate layer, a base layer, and a foundation layer. The top of the foundation layer is fixedly connected to the bottom of the base layer, and the top of the base layer is fixedly connected to the bottom of the first intermediate layer. The top of the adhesive layer has multiple evenly distributed raised diamond grooves.

[0004] In the aforementioned application, the precise coordination between the seamless surface layer and the prefabricated field layer components can effectively solve the deformation problem caused by thermal expansion and contraction, ensuring the stability of the overall structure under different temperature environments. However, this design lacks an effective positioning mechanism and connection method for handling the positioning and splicing between prefabricated slabs. During the splicing process, the prefabricated slabs are prone to slight misalignment or inaccurate alignment, which affects the flatness and strength of the overall structure. This may lead to a reduction in the performance of the structure in the later stages of construction, and even affect the durability and safety of the field. Therefore, we propose a seamless semi-prefabricated court structure that is easy to splice and position. Utility Model Content

[0005] The purpose of this utility model is to provide a seamless semi-prefabricated sports field structure that is easy to splice and position. Through the design of components such as mortise and tenon blocks, mortise and tenon grooves and elastic hook-shaped locks in the positioning mechanism, the problems of unstable splicing and inaccurate docking in the prior art are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a seamless semi-prefabricated sports field structure that is easy to splice and position, including a prefabricated slab one and a prefabricated slab two, and a positioning mechanism is provided inside the prefabricated slab one and the prefabricated slab two.

[0008] The positioning mechanism includes a tenon block, which is fixedly connected to the side of the first precast slab. The side of the second precast slab has a tenon groove, and the side of the first precast slab has a locking groove with an elastic hook-shaped lock inside. The side of the second precast slab has a positioning groove with a locking ring fixedly connected inside. The purpose of this is to ensure that the parts can be effectively aligned during splicing.

[0009] Furthermore, there are two mortise and tenon blocks and mortise and tenon grooves, which are symmetrical to each other along the vertical central axis of the precast slab. The purpose is to ensure that the precast slab can be more accurately connected during installation and effectively reduce deformation or misalignment caused by uneven stress, thereby further improving the stability of the overall structure and the reliability of long-term use.

[0010] Furthermore, the mortise and tenon block is designed to be dovetail-shaped, and the shape of the mortise and tenon block is adapted to the shape of the mortise and tenon groove. The purpose is that the dovetail structure can effectively prevent the mortise and tenon block and the mortise and tenon groove from falling off or shifting under lateral force or vibration, and ensure a firm connection during the splicing process.

[0011] Furthermore, the locking ring is located on the displacement trajectory of the elastic hook-shaped latch, the purpose of which is to ensure that the elastic hook-shaped latch can lock with the locking ring during the movement of the latch.

[0012] Furthermore, a sealing mechanism is provided between the precast slab one and the precast slab two. The sealing mechanism includes an inlay groove, which is opened on the side of the precast slab one and the precast slab two. The inlay groove is filled with elastic filler, the purpose of which is to fill the cracks in the precast slab one and the precast slab two under low temperature conditions by squeezing with the elastic filler.

[0013] Furthermore, the width of the elastic filler is greater than the width of the inlay groove, the purpose of which is to ensure that the inlay groove, in conjunction with the elastic filler, fills the crack by compression.

[0014] Furthermore, the number of the inlay grooves and elastic fillers is set to four, in pairs, and symmetrically arranged along the vertical central axis of the precast slab. The purpose is to optimize the stress distribution of the precast slab during splicing through symmetrical arrangement, ensure uniform compression and elastic absorption at the joint, and fill the cracks.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the interlocking of components such as mortise and tenon blocks, mortise and tenon grooves, and elastic hook-shaped latches in the positioning mechanism. During splicing, the mortise and tenon blocks on one side of the precast slab are first aligned with the mortise and tenon grooves on the other two sides of the precast slab. The mortise and tenon structure achieves initial positioning and lateral limitation. After initial positioning, the elastic hook-shaped latches on one side of the precast slab automatically engage with the locking ring to achieve mechanical locking, preventing the spliced ​​slabs from separating in the vertical direction or under stress. This locking process requires no additional tools, is easy to operate, improves construction efficiency, and ensures the long-term stability of the connection.

[0017] 2. This utility model utilizes the interplay between the inlay groove of the sealing mechanism and the elastic filler assembly. The inlay grooves on the sides of the precast slab one and the precast slab two are pre-installed with elastic filler, the width of which is slightly larger than the inlay groove. During the splicing process, the elastic filler is compressed and fills the gaps between the slabs to form an elastic sealing layer. This structure effectively prevents moisture, dust and other impurities from seeping into the joints, and can compensate for the changes in gaps through elastic deformation when the slabs expand and contract due to temperature changes, thus avoiding cracks and ensuring that the court surface is flat, seamless and durable.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is a seamless semi-prefabricated sports field structure that is easy to splice and position, including a prefabricated slab 1 and a prefabricated slab 2, and a positioning mechanism 3 is provided inside the prefabricated slab 1 and the prefabricated slab 2.

[0029] The positioning mechanism 3 includes a tenon block 31, which is fixedly connected to the side of the precast slab 1. The side of the precast slab 2 is provided with a tenon groove 32. The side of the precast slab 1 is provided with a locking groove 33. The locking groove 33 is provided with an elastic hook-shaped lock 34. The side of the precast slab 2 is provided with a positioning groove 35. The positioning groove 35 is fixedly connected with a locking ring 36. The purpose is to ensure that the parts can be effectively aligned during splicing.

[0030] There are two mortise and tenon blocks 31 and mortise and tenon grooves 32, which are symmetrical to each other along the vertical central axis of the precast slab 1. The purpose is to ensure that the precast slab 1 can be more accurately connected during installation and effectively reduce deformation or misalignment caused by uneven force, thereby further improving the stability of the overall structure and the reliability of long-term use.

[0031] The mortise and tenon block 31 is designed in the shape of a dovetail, and the shape of the mortise and tenon block 31 is adapted to the shape of the mortise and tenon groove 32. The purpose is that the dovetail structure can effectively prevent the mortise and tenon block 31 and the mortise and tenon groove 32 from falling off or shifting under lateral force or vibration, and ensure a firm connection during the splicing process.

[0032] The locking ring 36 is located on the displacement trajectory of the elastic hook-shaped latch 34, and its purpose is to ensure that the elastic hook-shaped latch 34 can lock with the locking ring 36 during the movement.

[0033] A sealing mechanism 4 is provided between precast slab 1 and precast slab 2. The sealing mechanism 4 includes an inlay groove 41, which is opened on the side of precast slab 1 and precast slab 2. An elastic filler 42 is provided inside the inlay groove 41. Its purpose is to fill the cracks in precast slab 1 and precast slab 2 under low temperature conditions by squeezing the elastic filler 42.

[0034] The width of the elastic filler 42 is greater than the width of the inlay groove 41. The purpose of this is to ensure that the inlay groove 41, in conjunction with the elastic filler 42, squeezes and fills the crack.

[0035] The number of inlay grooves 41 and elastic fillers 42 is set to four, in pairs, and symmetrical to each other along the vertical central axis of the precast slab-1. The purpose is to optimize the stress distribution of the precast slab-1 during splicing through symmetrical arrangement, ensure uniform compression and elastic absorption at the joint, and fill the cracks.

[0036] A specific application of this embodiment is as follows: Before using this sports field structure, precast slab 1 and precast slab 2 need to be transported to the construction site respectively, and the splicing surfaces need to be cleaned to ensure that there are no debris interfering. During splicing, the tenon block 31 on the side of precast slab 1 is first aligned with the tenon groove 32 on the side of precast slab 2. The tenon structure achieves preliminary positioning and lateral limitation. Since the tenon block 31 is designed as a dovetail, its cooperation with the tenon groove 32 not only facilitates the guiding insertion, but also effectively prevents it from falling off or shifting under lateral force or vibration, ensuring a firm and reliable connection. After the tenon structure is initially positioned, the workers press the precast slab 1. At this time, the elastic hook-shaped latch 34 on the side of precast slab 1 moves and the locking ring 36 moves. In conjunction with the locking ring 36, the panels automatically spring into place, achieving mechanical locking and preventing separation of the splicing panels in the vertical direction or under stress. This locking process requires no additional tools, is easy to operate, and improves construction efficiency. At the same time, the inlay grooves 41 on the sides of precast panels 1 and 2 are pre-installed with elastic filler 42. Since the width of the elastic filler 42 is slightly larger than the width of the inlay groove 41, during the splicing process, the elastic filler 42 is compressed and fills the gaps between the panels, forming an elastic sealing layer. This structure can not only effectively prevent moisture, dust, and other impurities from seeping into the joints, but also compensate for the changes in gaps through elastic deformation when the panels expand and contract due to temperature changes, avoiding cracks and ensuring that the court surface is flat, seamless, and durable.
