Abstract

PURPOSE:To allow a neighboring block to slide in a fitting direction by gravity so that the block is automatically fitted in by forming the mating surface of the block with a tilt in the direction to intersect any other mating surface. CONSTITUTION:Both ends of a block body 1 having projections 2, 2 are respectively made into a projecting tilted mating surface 31 for receiving a recessed tilted surface 31 of an adjacent block end and a recessed tilted mating surface 32 to ride on a projecting tilted surface of an adjacent block end. The mating surfaces 31, 32 are tilted in the same direction. On the other hand, the projections 2, 2 are provided with tilted mating surfaces 21, 22 tilted in the opposite direction to intersect the tilted mating surfaces 31, 32. The tilted mating surface 21 is on a recessed part and is placed on a projecting titled surface of an adjacent block. A tilted mating surface of an adjacent block in the recessed part is placed on a tilted mating surface 22 of the projecting part.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application The present invention relates to ring blocks that are continuously laid and connected to road surfaces, stacked blocks used for lining slopes, foot protection,
This article relates to laying blocks such as blocks that are installed in series for waterworks, etc., and relates to the method of connecting them and the blocks used for this.

(B) Conventional technology Conventionally, the end faces of a laying block with adjacent blocks were joined by butting the end faces of a sidewalk flat plate and using joint mortar. Simply join the end faces perpendicular to the laying surface, such as by welding it at the end and filling it with mortar, or by adding a retaining part such as a block for slope lining to increase the joint area, and finishing the joint end with joint mortar. method was adopted, and countermeasures such as block structures or interconnected structures to deal with pressure on the lining surface were rarely considered.

(C) Problems to be Solved by the Invention In conventional laying blocks, the end faces of the laying blocks are joined by arranging the end faces perpendicular to the lining surface as close as possible to adjacent blocks, and filling the gaps with joint concrete, etc. However, it has been assumed that a sophisticated technique is required to arrange the blocks closely, and gaps between adjacent blocks naturally occur. Furthermore, in some cases, a great deal of labor and time was required, such as cutting out part of the block to expose reinforcing bars, welding them together at the joints, and filling them with mortar. In addition, the pressure applied to the lining surface is directly applied to the foundation ground, so in the case of roads or floors on which heavy objects are placed, it is necessary to strengthen the foundation ground before lining. The problem was that it was relatively expensive, similar to asphalt pavement. Furthermore, if reinforcement is required, such as a floor surface on which heavy objects are placed, conventional asphalt pavement cannot withstand long-term storage of such heavy objects, so the floor surface is paved with cast-in-place concrete. It's here. These projects took a long time to construct, required a lot of concrete, and were extremely wasteful considering the amount of reinforcing steel.

(d) Means for Solving the Problems The present invention solves the above-mentioned problems by a method of strengthening the interlocking joints of the end faces of the blocks, and utilizes the weight of the blocks to join the end faces with adjacent blocks by means of intersecting slopes. By doing so, the end faces are automatically joined with the adjacent blocks, and due to the end faces, the joint slopes mutually support each other's gravity to form a load-bearing structure against pressure on the lining surfaces.

(e) Formed on the action slope. Since the joining surface is inclined in a direction that intersects the inclination angle of one of the other joining surfaces, the adjacent block that joins it will slide in the fitting direction due to gravity and fall between the intersecting inclination angles. will automatically fit together.

Therefore, gravity acts in a direction that strengthens the connecting joints of the end faces of the blocks, and the load on the lining surface is supported by the load-bearing structure of the connecting blocks.

(f) Example Hereinafter, the present invention will be described in detail with reference to the drawings.

1 has a main body with a protruding portion 2.2 extending in a direction perpendicular to the main body, and both ends thereof form a joining slope 31.32 with an adjacent protrusion to be connected. The joining slopes 31 and 32 are inclined in the same direction, and 3
1 is a convex slope on which the end slope 41 of the adjacent block A is placed, and 32 is a concave slope on which the end slope 42 of the adjacent block B is placed. The provided joining slopes 21, 22 are inclined in the opposite direction intersecting the main body joining slopes 31, 32, and 21 constitutes a concave slope and 22 constitutes a convex slope.

First, when the joining part 31, the concave slope 41, 32 of block A, and the convex slope 42 of block B are joined and connected laterally, a fitting space 20 into which the overhanging part 5 of the adjacent block D fits is formed, and this is inserted. When connected in the vertical direction, the overhang part 2
The joining slope 21 of block D and the overhang joining slope 51 of block D are joined, and the overhang joining slope 43 of block A and the overhang joining slope 52 of block D are joined, respectively.

The main block fits into the intersecting slope formed by the convex slope 42 of block B and the convex slope 51 of block D, making it stable in position, and the slopes mutually support each other's gravity to strengthen the connection and connect firmly. do.

FIG. 3 shows another embodiment, in which the joining slopes 31 and 32 at both ends of the main body are inclined in opposite directions, and the slopes of the main body and the overhang also change accordingly, as shown in FIG. Adjacent blocks will be inserted alternately from opposite directions. Of course, it is not necessary for all of the joining slopes to form intersecting slopes with each other, and it is sufficient to form an intersecting slope with the slope angle of any of the joining surfaces, so various changes can be made in addition to the examples shown here. and various implementations are possible.

In the case of a machi block, the load-bearing structure can be sufficiently strengthened even if the retainers are left as conventional and are applied only to the joint surfaces.

(g) Effects of the Invention Since the present invention is constructed as described above, by reinforcing the load-bearing structure of the block itself, such as by inserting reinforcing bars into the block, it is possible to reduce the weight by simply laying the block without having to harden the foundation ground. This makes it possible to provide load-resistant linings for floors, etc. on which objects are placed. Therefore, unlike conventional blocks, there is no need for joint mortar or connecting fittings, and the construction is completed once the laying is completed, which has a great effect. In addition, since the laying of the blocks in parallel is automatically positioned by joining the slopes, no skill is required, and the work of adjacency and horizontal adjustment can be simplified.
