Description

Technical Field

[0001] The present application relates to the technical field of tree pit stones, and in particular to a combined prefabricated tree pit stone. Background Art

[0002] In recent years, with the continuous improvement of my country's national economic level, urban construction has also accelerated. In urban construction, landscape construction occupies an important position and has become the focus and highlight of urbanization transformation. Road landscape is the most intuitive carrier to show people the image of the city. Street trees are an important part of road greening. Tree pits, as carriers of street trees, bear the function of protecting trees. They are an important part of the sidewalk and a highlight of the road landscape. Unified and beautiful tree pits make street trees grow better and add greenery to urban roads.

[0003] Usually, tree pit stones are set around the tree pit to separate the tree pit from the sidewalk structure to protect the tree roots and promote the growth of street trees. Existing tree pit stones mostly use four or eight equal-length tree pit stones to form a square or circular tree pit. This type of tree pit structure has the following shortcomings: 1) The inner structure is relatively hollow and the outer structure is relatively solid, which may cause quality risks such as misalignment or breakage in the middle during later extrusion; 2) When using segmented combination, there is an obvious seam in the middle, which affects the appearance of the tree pit structure; 3) The tree pit stones with 45° beveled ends are prone to missing edges and corners during transportation and installation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a combined prefabricated tree pit stone in view of the above-mentioned problems. The combined tree pit is formed by four strip-shaped tree pit stones and four L-shaped tree pit stones surrounding the tree pit.

[0005] The embodiment of the present application is implemented as follows:

[0006] An embodiment of the present application provides a combined prefabricated tree hole stone, characterized in that it includes four strip-type tree hole stones and four L-shaped tree hole stones, and the two ends of the strip-type tree hole stone and the two ends of the L-shaped tree hole stone are respectively provided with corresponding clamping structures, and the two ends of the L-shaped tree hole stone are respectively clamped and connected with the strip-type tree hole stone to form a quadrilateral tree hole.

[0007] In some optional embodiments, the clamping structure includes a clamping protrusion and a groove, and the clamping protrusion and the groove are respectively arranged on the end faces of the correspondingly connected strip-shaped tree pit stone and the L-shaped tree pit stone.

[0008] In some optional embodiments, the clamping protrusion is a U-shaped screw pre-buried in the strip-type tree hole stone or the L-shaped tree hole stone, and the ends of the two screws of the U-shaped screw are exposed on the end faces of the strip-type tree hole stone and the L-shaped tree hole stone.

[0009] In some optional embodiments, the groove is provided on the end surface of the L-shaped tree pit stone or the strip-shaped tree pit stone corresponding to the U-shaped screw.

[0010] In some optional embodiments, the groove is filled with epoxy mortar.

[0011] In some optional embodiments, the U-shaped screw is a U-shaped galvanized screw.

[0012] In some optional embodiments, the exposed length of the two screws of the U-shaped screw is half of the total length of the screw.

[0013] In some optional embodiments, the installation height of the U-shaped screw is 1 / 2 of the height of the strip-shaped tree pit stone and the L-shaped tree pit stone, and the horizontal center is located at 1 / 3 of the width of the tree pit stone.

[0014] The beneficial effects of the present application are as follows: a combined prefabricated tree pit stone provided by the present application adopts a snap-in structure at the end of the prefabricated tree pit stone, and four strip-shaped and four L-shaped tree pit stones are snap-connected in pairs to form a closed combined tree pit, which is quick to install and has a stable overall structure; there is no 45° bevel at the end, which overcomes the problem of easy edge and corner damage during transportation and installation of the tree pit stone after leaving the factory; it overcomes the disadvantage that the segmented combination line of large prefabricated tree pit stones is not easy to be straight, and the line is beautiful; according to different design requirements, tree pits with different inner edge lengths can be achieved by adjusting the length of the strip-shaped prefabricated tree pit stone, avoiding the mold opening of a whole set of prefabricated tree pit stone templates and saving mold opening costs.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0023] The features and performance of the present application are further described in detail below in conjunction with the embodiments.

[0024] like Figure 1 As shown, the utility model provides a combined prefabricated tree hole stone, including four strip-type tree hole stones 1 and four L-shaped tree hole stones 2. The two ends of the strip-type tree hole stone and the two ends of the L-shaped tree hole stone are respectively provided with corresponding clamping structures, and the two ends of the L-shaped tree hole stone are respectively clamped and connected with the strip-type tree hole stone to form a quadrilateral tree hole.

[0025] like Figure 2 As shown, the clamping structure includes a clamping protrusion 3 and a groove 4, which are respectively arranged on the end faces of the correspondingly connected strip-shaped tree pit stone and the L-shaped tree pit stone. The groove is filled with epoxy mortar, so that the strip-shaped and L-shaped tree pit stones are squeezed against each other, so that the entire combined tree pit stone is stable and not easy to deform.

[0026] Fill the groove with epoxy mortar before assembly. When installing the combined prefabricated tree pit stone structure, the adjacent strip prefabricated tree pit stones should be set perpendicular to each other. The four L-shaped prefabricated tree pit stones should be set at the corners of the strip prefabricated tree pit stones placed perpendicular to each other. The combined prefabricated tree pit stone structure should be leveled to make the strip and L-shaped structures tightly connected to each other. After the installation is completed, the joints between the strip and L-shaped structures should be watered and maintained to prevent the epoxy mortar from cracking.

[0027] Example 1

[0028] The convex part is a U-shaped screw pre-buried in a strip-shaped tree hole stone or an L-shaped tree hole stone, and the ends of the two screws of the U-shaped screw are exposed on the end faces of the strip-shaped tree hole stone and the L-shaped tree hole stone; the groove is arranged on the end face of the L-shaped tree hole stone or the strip-shaped tree hole stone corresponding to the U-shaped screw.

[0029] The U-shaped screw is a U-shaped galvanized screw to prevent damage during transportation, breakage due to external force after installation, or rust and breakage due to rain corrosion in the later stage, which will affect the overall line shape and stability of the prefabricated tree pit stone structure.

[0030] The exposed length of the two screws of the U-shaped screw is half of the total length of the screw; the installation height of the U-shaped screw is 1 / 2 of the height of the strip-type tree hole stone and the L-type tree hole stone, and the horizontal center is located at 1 / 3 of the width of the tree hole stone.

[0031] Example 2

[0032] Specific edge dimension design of strip and L-shaped prefabricated tree pit stones:

[0033] The length of the L-shaped tree hole stone is L1, the width is L2, and the height is H1. The lengths of the two sides of the L-shaped tree hole stone are L3 and L4 respectively, the corresponding widths are L6 and L6, and the height is H2=H1.

[0034] Among them, L1 = the inner side length of the tree hole stone design - 2*(150+3), L2 = 150mm, and 3mm means that there is a 3mm installation gap between the vertical surfaces corresponding to the strip-type tree hole stone and the L-type tree hole stone, which is convenient for the installation of the tree hole stone. L3 = L4 = 300mm, L5 = L6 = 150mm. The convex parts set at both ends of the L-type tree hole stone adopt pre-buried U-shaped galvanized M16 screws, with a leg length of 160mm and an exposed length of 80mm; the installation height of the pre-buried U-shaped galvanized M16 screw is 1 / 2 of the height of the tree hole stone, and the horizontal center is located at 1 / 3 of the width of the tree hole stone. The inner diameter of the grooves set at both ends of the strip-type tree hole stone is 20mm and the depth is 10mm, which is convenient for filling epoxy mortar.

[0035] The combined tree pit consists of four strips and four L-shaped tree pit stones. The outer side is a sidewalk structure and the inner side is planted with soil. The strips and L-shaped tree pit stones are connected by clamping and filled with epoxy mortar, so that the strips and L-shaped tree pit stones are squeezed against each other, making the entire combined tree pit stone stable and not easy to deform.
