Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, building block interfacial structure, is characterized in that: building block 1 side surface has horizontal groove 2, is divided into upper, middle and lower three rows, every layer of horizontal groove 2 all around building block in the form of a ring; In building block 1 side, one vertical slot 3 is set, and connects with transverse groove 2; Building block 1 bottom surface arranges the salient point 4 mating with geo-grid mesh, and two adjacent salient point clear distances ensure while meeting salient point along horizontal or lengthwise movement that having the necessary condition of a salient point interband headroom at least is d=2+14k, and k is natural number.
Salient point quantity on described building block 1 bottom surface is 4n, and wherein n is positive integer.
As shown in Figure 1-2, when work, place corresponding building block 1, make the building block on narrow limit corresponding with transverse groove 2 positions in broadside building block, assembled rear transverse groove 2 make-ups present duct shape hole, mortar injection be full of the netted mortar ring of hole formation while building by laying bricks or stones, plays the vertical effect of sliding along side between restriction building block just as mortise and tenon.
One vertical slot 3 is set in building block side, and connects with transverse groove 2.In groove, after perfusion mortar, become one with three layers of mortar ring, as Bird's Nest, play and build space multistory net structure, and have the effect that increases mortar ring intensity.This vertical slot 3 can also be served as fixture locating slot and be used in building block transport and assembled operation.
Because building block 1 material is concrete, at concreting mould inside, outstanding transverse groove 2, vertical slot 3 and bottom groove 5 are set and complete each groove and salient point manufacture can be at concreting time.
In order to increase the side-friction of single building block and subbase, prevent building block assembly generation lateral displacement, design considers to utilize rubble, the two-way tensile stress geo-grid composition of steel band salient point laterally and longitudinal constraints, simultaneously in order effectively to utilize to the full extent above-mentioned constraints, several salient points 4 are set in building block bottom surface, utilize the restraint forces between salient point 4 and rubble grid to form interlocking, meet the designing requirement of road structure.According to above-mentioned principle, it is very important that the size of salient point 4 and position seem, the outward appearance of steel band geo-grid is square grid shape, interband headroom is 12cm, bandwidth is 2cm, the randomness of laying while assembling due to building block, need to solve bottom surface salient point 4 and how guarantee salient point 4 is set drops on the maximum probability problem of interband headroom.First pass through the checking computations of structural mechanics, the suitable dimensions of having determined single salient point 4 is the circular salient point of diameter 5cm, thickness 2cm.Suppose that bottom surface arranges 4 salient points, and in the time that the distance of two horizontal and vertical salient points 4 meets salient point along horizontal or lengthwise movement, ensureing to have the necessary condition d=2+14k(k of salient point 4 interband headroom at least is natural number), as shown in Figure 4: moved on grid band time when controlling two salient points 4, while movement along the vertical direction of moving direction, because the spacing of two other salient point 4 also meets the necessary condition that ensures to have at least salient point 4 interband headroom in the time that the distance of two horizontal and vertical salient points 4 meets salient point 4 along horizontal or lengthwise movement, therefore, will inevitably meet and have at least a salient point 4 to drop in interband headroom, in sum, when building block bottom surface arrange salient point 4 meet below when two conditions, can inference when having a salient point 4 at least in the time that road direction is placed at random, building block 1 monomer can fall into grid headroom:
Condition 1: building block bottom surface salient point quantity is that 4n(n is positive integer).
Condition 2: it is natural number that adjacent two salient point clear distances ensure to have the necessary condition d=2+14k(k of a salient point interband headroom at least while meeting salient point along horizontal or lengthwise movement).
According to building block bottom surface real size, we arrange 8 salient points altogether.
