The described first through hole 2a and the second through hole 2b are 7 (for the checkerwork cell diameters about 40mm), 19 (for the checkerwork cell diameter about 30mm) or 37 (for the checkerwork cell diameter about 20mm); Described detent 5b, locating convex block 5a, combination groove 3a is circle with the cross section of combination projection 3b, detent and combination groove all are that the big bottom surface of opening surface is little, locating convex block and combination projection all are that end face is little and the bottom surface is big, the bottom surface of combination groove 3a is greater than the end face of combination projection 3b, opening surface is greater than the bottom surface of combination projection 3b, the bottom surface of detent 5b is greater than the end face of locating convex block 5a, opening surface is greater than the bottom surface of locating convex block 5a, the size of combination projection 3b is less than the size of locating convex block 5a, and the size of combination groove 3a is less than the size of detent 5b; The aperture of described circular passage is first through hole or second through-hole diameter 1.5-2.5 times; Structure when the described brick that lattices is piled up is, the central point line of per 3 bricks that lattice is equilateral triangle and arranges, central upper portion is placed the brick that lattices, each side of the brick that lattices on top side corresponding with the same direction of 3 bricks that lattice of bottom respectively parallels that (this just descends the stacking of one deck brick and last layer brick to place by this dislocation mode, and the location of stacking is realized by the mutual interlock of locating convex block 5a and detent 5b), the detent 5b of the locating convex block 5a of the brick that lattices of bottom and the brick that lattices on top is interlocked mutually; It is big that the described first through hole 2a and the second through hole 2b are stomidium footpath, the taper that the other end aperture is little; Described combination projection 3b places between per two first adjacent half slot 4b; Described combination groove 3a places between per two first adjacent half slot 4a.
From the above, this brick that lattices is made up of (about setting by placement location upper and lower two half blocks, so-called is half block, refer to compare with existing checker brick, the height that in height has only existing grid lattice 1/2), the profile of any one half block is the same with cellular checker brick to be parallel positive six prisms of end face, arranges to arrange combination projection and combination groove by equilateral triangle respectively in the lower surface of last half block and the upper surface of following half block, to realize the combination between the upper and lower half block; Equally, also adopt in the lower surface of the upper surface of last half block and following half block and arrange to arrange locating convex block and detent by equilateral triangle respectively, pile up or pile up to finish the location that lattices between the brick; Its cross section of projection on the checker brick end face and groove is circle, and the design upper groove is that opening surface is big and the bottom surface is little, and projection is that end face is little and the bottom surface is big; For cooperating between groove and the projection, the bottom surface of groove is greater than the end face of projection, and the opening surface of groove is greater than the bottom surface of projection; The upper surface of the lower surface of the last half block of this brick that lattices and following half block arrange respectively with the checker brick center be symmetry, perpendicular to three half slots of checker brick six prismatic planes; Just form three circular passages that connect checker brick when upper and lower half block fits in when latticing brick in the middle of it, perhaps six from the center radial circular passage.
