Abstract
The utility model relates to a combined grate which comprises an outside square member and an inner circular member. The inner circular member consists of a plurality of semicircular arc plates. Butt seams of the end surfaces of the semicircular arc plates and adjacent butt seams in the assembly are distributed in a staggered manner by 90 degrees. All the arc contact surfaces of the semicircular arc plates in the assembly are in slope butt joint with one another in one direction. According to the combined tree grate, a plurality of screws are fastened on strip-shaped iron plates below the tree grate, so as to ensure the completeness and surface smoothness of the assembly. The combined tree grate is overhung the soil surface of a tree pool, looks like the existing iron tree grate and is even superior to the existing iron tree grate. The combined tree grate can be beneficial for tree root watering and water holding, provide a necessary condition to solve the problems that soil is exposed out of the tree pool and dust is raised from the tree pool, and completely overcome the defects of traditional tree grates.
Description
Technical field
The utility model relates to a kind of tree grating grid that is used to set the pond cover plate, particularly relates to a kind of combined type tree grating grid.
Background technology
The tree pond of not having enough time to add a cover in present urban human street tree pond is everywhere; That babbles greatly one by one exposes usage tree root soil; Cause airborne dust easily, and the tree pond that has about the half chi degree of depth all is arranged in the both sides, pavement, in the area, tourist hot spot that the crowd is dense; Cause pedestrian's pin of rivering bend easily, the tragedy that has an accident.On one, two types of streets, Beijing, big mouth is much all opened in tree pond in a row, and carelessness person reserves a seat for sb..External tree pond is each big city of the U.S. of representative with New York, all will set and apply full white cobblestone in the pond; Add the water-permeable and air permeable lid of hollow out above; This hollow out lid can be that cement products also can be the cast iron lid, and each lid all has suitable precision, and the people does not step on can rock the pin of rivering bend.The tree pond of Germany also is to add a cover hollow out lid, but the precision of lid is to have national standard to follow, and the circularity of each lid and squareness be standard very all; Thickness and flatness are very good; Two lid joint precision are very high, good planeness not only, and also thickness is moderate; Can not cause owing to lid is too thin and rock, this high accuracy lid embodies the outstanding quality that Germany makes.
Tree pond in that China has is floating with permeable sandstone material disposable integral; The fragmentation of tree root growth material protuberance causes damage after one or two years; Involve great expense with the sago cycas grate, and be prone to lose, also have some tree grating grid to constitute, directly be placed in to cause in the tree pond and compile rainwater and irrigation water difficulty by two or four blocks of thick and heavy concrete; There have the surface to be difficult to again to be smooth, causes the tree pond to lose basic role.
Summary of the invention
The utility model combined type tree grating grid is to overcome the above-mentioned defective of prior art, the tree grating grid that provides a kind of square-outside and round-inside two members to be combined into one, and the compact conformation surfacing, overall construction intensity is high, meets the combined type tree grating grid that urban afforestation beautifies demand.
For realizing above-mentioned purpose, the utility model combined type tree grating grid is made up of square-outside and round-inside two members, and interior round member is made up of a plurality of semicircular arc plates.Through semicircular arc plate end face abutment joint in the assembly and adjacent end face abutment joint, be in staggered distribution by an angle of 90 degrees.Arc contact surface through all semicircular arc plates in the assembly is a direction inclined-plane butt joint again.Having has a plurality of screws to add to be affixed to below the tree grating grid on the strip iron plate again above the tree grating grid, guaranteed complete one of combined type tree grating grid and surfacing.
As optimization, combined type tree grating grid semicircular arc plate end face abutment joint and adjacent end face abutment joint are in staggered distribution by an angle of 90 degrees.So design meets the semicircular arc board component and docks requirement attractive in appearance and can improve combined type tree grating grid intensity.
As optimization, the arc contact surface of all semicircular arc plates is a direction inclined-plane butt joint.So design is mainly and guarantees this assembly surfacing, improves combined type tree grating grid support strength.
As optimization, have a plurality of screws to add above the combined type tree grating grid to be affixed to below the tree grating grid on the strip iron plate.So design is complete one combination of realization combined type tree grating grid and raising combined type tree grating grid overall construction intensity, and is difficult for losing.
As optimization, there are carved pattern and mold pressing decorative pattern in combined type tree grating grid surface, and decorative pattern is concaveconvex shape and hollow out shape on the surface.So design, for the concaveconvex shape decorative pattern has anti-skidding effect, hollow out shape decorative pattern has the air-vent effect, and decorative pattern is a beautification function.
Because adopt above technical scheme, the combined type tree grating grid is more scientific and reasonable.Make the standardization of combined type tree grating grid; Seam crossing is exquisite, and surface smoothness is good, and thickness can be according to the tree grating grid selection that is of moderate size; Can not cause and rock owing to tree grating grid is too thin; Can tree grating grid yet too thick and influence tree pond retaining, demonstrate fully the optimal design of the utility model combined type tree grating grid, not only be beneficial to people's walking but also satisfied urban afforestation and beautified demand.

Embodiment
Be further described below in conjunction with accompanying drawing and instantiation:
Embodiment, shown in Fig. 1-3, the utility model combined type tree grating grid is that square-outside and round-inside two members are formed.Outer square member 1, interior round member is made up of a plurality of semicircular arc plates 2,3,4.Outer square member 1 interior circle is a direction inclined-plane with the arc contact surface 8 of semicircular arc plate 2,3,4 and docks.Semicircular arc plate 2,3,4 end faces, 9 abutment joints and adjacent end face abutment joint, be in staggered distribution by an angle of 90 degrees.Circle member 2,3,4 has carved pattern 6,7 or mold pressing decorative pattern 6,7 in the outer square member 1, and decorative pattern 6,7 is concaveconvex shape or hollow out shape on the surface.Have a plurality of screws 5. to add above the outer square member 1 semicircular arc plate 2,3,4 to be affixed to below the tree grating grid on the strip iron plate.
