Abstract
Description
Technical Field
[0001] This utility model relates to the field of urban furniture and landscape greening technology, specifically a modular tree grate with a mortise and tenon structure. Background Technology
[0002] Street trees are an important component of the urban landscape. Tree grates are often used in urban furniture, and are a part of urban furniture, commonly used in landscaping, municipal construction, and other applications. Although small, tree grates are an important reflection of a city's high quality and a crucial element of refined urban construction.
[0003] In practical applications, traditional tree grates have been found to have certain shortcomings. For example, when traditional tree grates are damaged, they must be replaced entirely at once, which is costly. While leaving the tree pit exposed without grates facilitates rainwater inflow and tree growth, it also results in long-term soil exposure and negatively impacts the urban environment. Furthermore, traditional tree grates cannot address the issue of tree roots not being centered in the tree pit. To address these shortcomings, a modular tree grate with a mortise and tenon joint structure has been proposed. Utility Model Content

[0006] According to this utility model, the inner ring tree grate further includes a fourth tree grate module and a fifth tree grate module that are mortise and tenon connected to each other. The fifth tree grate modules are evenly arranged along the inner ring, and multiple fourth tree grate modules are mortise and tenon connected between two adjacent fifth tree grate modules to form the inner ring tree grate together.
[0007] According to this utility model, the intermediate tree grate is formed by tenon and mortise joints connecting multiple third tree grate modules into a ring shape, with the inner side of the third tree grate module connected to the inner ring tree grate module by tenon and mortise joints, and the outer side of the third tree grate module connected to the outer ring tree grate module by tenon and mortise joints.
[0008] According to this utility model, the outer ring tree grate further includes a first tree grate module and a second tree grate module connected by mortise and tenon joints. The first tree grate modules are evenly arranged along the outer ring, and multiple second tree grate modules are connected by mortise and tenon joints between two adjacent first tree grate modules to form the outer ring tree grate together.
[0009] According to this utility model, a groove is further provided on the end face of the outer ring tree grate that contacts the floor tile.
[0010] According to this utility model, the fourth grate module is further provided with water-permeable holes.
[0011] According to this utility model, the third grate module is further provided with water-permeable holes.
[0012] According to this utility model, the first grate module and the second grate module are provided with water-permeable holes.

[0028] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.
[0029] The structure and effects of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Please see Figures 1-6 A modular tree grate with a mortise and tenon structure includes an inner ring tree grate, a middle tree grate mortised and tenon-jointed with the inner ring tree grate, and an outer ring tree grate mortised and tenon-jointed with the middle tree grate. The outer ring tree grate contacts the end face of the floor tile, and a groove is formed on the end face of the outer ring tree grate in contact with the floor tile. Tree grates of any size can be assembled from multiple tree grate modules of the same or different types, and the problem of eccentric tree grates can also be solved.
[0031] In this embodiment of the application, the inner ring tree grate includes a fourth tree grate module 4 and a fifth tree grate module 5 that are mortised and tenoned together. There are four fifth tree grate modules 5, which are evenly arranged along the inner ring. Multiple fourth tree grate modules 4 are mortised and tenoned between two adjacent fifth tree grate modules 5, which together form the inner ring tree grate.
[0032] The central tree grate is formed by mortise and tenon joints connecting multiple third tree grate modules 3 into a ring. The inner side of the third tree grate module 3 is connected to the inner ring tree grate with mortise and tenon joints, and the outer side of the third tree grate module 3 is connected to the outer ring tree grate with mortise and tenon joints. Preferably, the central tree grate has multiple rings, and adjacent rings are connected by mortise and tenon joints of third tree grate modules 3.
[0033] The outer ring tree grate comprises a first tree grate module 1 and a second tree grate module 2 connected by mortise and tenon joints. There are four first tree grate modules 1, evenly arranged along the outer ring. Multiple second tree grate modules 2 are mortised and tenon jointed between adjacent first tree grate modules 1, collectively forming the outer ring tree grate. Preferably, both the outer end faces of the first tree grate 1 and the second tree grate module 2 are provided with grooves.
[0034] In this embodiment, the first tree grate module 1, the second tree grate module 2, the third tree grate module 3 and the fourth tree grate module 4 are provided with water-permeable holes 6 for providing greening nutrients to the soil.
[0035] In this embodiment, if the area of the tree grate is small, the third tree grate module 3 can be omitted, and the inner ring tree grate can be directly connected to the outer ring tree grate by mortise and tenon joints.
[0036] This section explains that the mortise and tenon structure described above consists of a tenon (protruding part) and a mortise (recessed part). After the mortise and tenon are connected, a gap of about 10 millimeters will be left for permeable drainage.
