[0001]

[Industrial applications]

 The present invention relates to a concrete basin that temporarily stores and discharges drainage water, sewage, etc., and in particular, a connecting ring for a concrete basin block for stacking the basin blocks that make up the concrete basin and a stacking joint for the concrete basin using the ring. Regarding structure.

[0002]

[Prior art]

 In order to temporarily store wastewater and sewage discharged from homes and discharge it to sewage, a cylindrical or prismatic concrete stake is used. When installing this basin, a hole is dug in the ground, a concrete foundation is formed at the bottom of the hole, and basin blocks are sequentially stacked on it to install the basin. An example of the prior art of such a cross-section of a basin and its joint is shown in the attached FIG. That is, as shown in the figure, the concrete cell 1 in FIG. 6 is stacked on the lowermost basic block 2, the two adjustment-side blocks 3 and 4 stacked on the basic block 2, and the uppermost block. It consists of edge block 6. The end faces of the joints of each of these blocks are inclined (sloping downward from the outer side toward the inner peripheral side) so as to fit each other, or are horizontal for abutting.

[0003]

[Issues to be solved by the device]

 However, in the above-mentioned conventional concrete block joint structure, when installing a concrete block, mortar is applied to the upper end surface of the concrete block and the next concrete block is stacked, but it is inserted at the joints of these upper and lower concrete blocks. Since the bonded mortar has a joint end face that slopes downward from the outside to the inside, or is parallel, the joint (that is, , Between the end faces) spilled into the stool, which necessitated refilling and repainting of the mortar, which took time to fix and also to clean the mortar that fell into the stool. There was a problem that it took time and effort.

[0006] Furthermore, in particular, the adjustment side blocks 3 and 4 are structurally fragile because they have no height and no edges, and after installation, they are backfilled with earth and sand, so that vehicles, heavy equipment, etc. When passing, it is easy for cracks to occur due to the pressure from the side (earth pressure), so replacement and repair are often necessary. Mortar joints are used to join the joints on the end faces of the Masu block.However, since the joint faces are parallel or sloped as described above, especially the leveling of earth and sand, the leveling of crushed stone, and the paving work. When heavy machinery or vehicles are used in the vicinity, etc., pressure is applied laterally or diagonally to these blocks. As a result, even if the mortar is used to fix the mortar, the joints between the slab blocks are easily destroyed, and the slab blocks stacked on top move horizontally to dislocate or disengage, or the bottom block block. There was a problem that the slab block rotated and slanted while it was in contact with the edge of the two points. Especially in the case of leveling earth and sand or laying crushed stones, the earth and sand and crushed stones may enter the gravel and the pipes connected to the side wall of the gravel from the misaligned joints. It took a lot of work to remove the. Furthermore, if it is displaced due to pavement work, the finished part must be destroyed and repaired.

Therefore, in the present invention, it is possible to solve the above-mentioned problems in the conventional technique and sufficiently secure the bonding strength between the concrete block blocks to be installed by vertically stacking the concrete block blocks. At the same time, it is an object of the present invention to provide a new ring for connecting concrete slab blocks, which is also excellent in joining work, and a stacking and joining structure for concrete stakes using this ring.

[0006]

[Means for solving the problem]

 In order to achieve the above-mentioned object of the present invention, according to the present invention, a connecting ring used in a joint structure of a plurality of stacked concrete stake blocks is formed by forming a belt-shaped member into a ring shape. However, there has been proposed a ring for connecting concrete concrete blocks, in which a flange portion is formed outward from the outer peripheral surface thereof.

Further, according to the present invention, as a stacking and joining structure of concrete concrete blocks, which is formed by stacking a plurality of concrete concrete blocks using the above-mentioned connecting ring of the concrete concrete blocks, Insert the brim of the connecting ring between the upper end surface and the lower end surface of another concrete slab block to be stacked on top of it and apply a bonding material to bond them, and then stack them on top of each other. There has been proposed a stacking and joining structure of concrete stakes in which the strip-shaped members of the connecting ring are arranged along the inner circumference of the joining portion of the cleat slab block.

[0008]

[Action]

 In other words, by using the above-proposed connection ring for concrete slab blocks according to the present invention, the upper end surface of a concrete stake block made up of a plurality of concrete stake blocks and other concrete slabs stacked on it. It is possible to secure the strength of the joint structure between the lower end surface of the slab block and the joint material applied to the joint surface, as well as the ring-shaped band-shaped member arranged along the inner circumference of the joint. become. This connecting ring has its flange inserted between the upper end surface of the concrete concrete block and the lower end surface of the other concrete concrete block that is piled up on it. Will be placed along.

Further, by using the connection ring for the stacking and joining structure of the concrete basins according to the present invention as proposed above, it also serves as a guide and a temporary fixing function for the basin blocks to be stacked on the joint surface. It is also excellent in work.

[0010]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a side cross-section of a cylindrical drainage or sewage basin in which a plurality of (4 tiers) concrete basin blocks are stacked by using the connecting ring according to the present invention. In this figure, a box is indicated by reference numeral 10, and this box 10 is, for example, a concrete block which is a precast product manufactured in advance in a factory, that is, a basic block 11 at the lowermost stage and stacked on it. The two adjustment-side blocks 12 and 13 and the edge block 14 that is stacked on the uppermost stage are stacked in four stages. Particularly, a plurality of thin portions 15, 15 ... For forming a hole when connecting a water distribution pipe are formed on the side wall surface of the basic block 11 in the lowermost stage. When installing this basin 10, first dig a hole at the installation site, form a concrete base at the bottom of this hole, place the basic block 11 on it, and then adjust the adjustment block 12 in the direction of the drawing. , 13 and the edge block 14 are sequentially stacked. Finally, the upper end of the edge block 14 is covered with a lid (not shown) made of concrete or metal after the installation work is completed.

Next, FIG. 2 attached herewith shows a connecting ring 20 which is used at a joint portion which is a joint end surface between the respective block blocks constituting the above-mentioned rod 10. As is apparent from the drawing, the connecting ring 20 includes a frame portion 21 formed by forming a belt-shaped member into a circular ring shape, and a flange portion 22 outward from the outer peripheral surface thereof. As is also shown, the cross section has a substantially “T” shape. The connecting ring 20 is made of metal such as cast iron, stainless steel, aluminum, or resin such as vinyl chloride.

A stacking and joining structure of concrete stakes, which is joined while stacking the respective stake blocks by using the connecting ring 20 having the structure described with reference to FIG. 2, will be described below. First, as described above, the basic block 11 is placed on the formed concrete foundation and fixed with mortar. After that, the connecting ring 20 shown in FIG. 2 is provided on the upper end surface which is the joining portion of the basic block 11, the frame portion 21 is the upper end inner peripheral surface of the basic block 11, and the flange portion 22 is the upper end surface. The mortar, which is the bonding material 30, is laid on it. Alternatively, the connection ring 20 may be placed after the mortar has been applied, and then the connection ring 20 may be applied further.

After that, while the adjustment block 12 is being hung by, for example, a crane, it is moved from above so that the lower end surface is placed on the upper end surface of the basic block 11. As a result, as shown in FIG. 3, the upper end surface of the basic block 11 and the lower end surface of the adjustment block 12 are joined to each other by mortar while facing each other. At this time, as is clear from the figure, the mortar sandwiched between the upper end surface of the basic block 11 and the lower end surface of the adjustment-side block 12 has a joint surface inclined inward, This mortar does not fall into the inside of the rod 10 because it is blocked by the frame portion 21 of the connecting ring 20, particularly the portion projecting upward from the upper end surface of the basic block 11, and The protrusions in the upper half temporarily fix the adjustment-side blocks 12 stacked on the joint end face, and even if pressure is applied from the lateral direction, their positions do not deviate from each other and good positioning is achieved. Moreover, since the joint is integrated by the connecting ring 20, the joint strength between the upper and lower blocks (in particular, against the lateral force) is increased. It is also achieved. Needless to say, the above effect is achieved not only when the joint surface is inclined, but also when the joint portion is horizontal.

Further, by utilizing the connecting ring 20 as a joint between the block blocks, the protrusion of the frame portion 21 to the upper side makes it possible to adjust the height of the joint (that is, between the end faces). The mortar to be inserted in) does not spill into the basin and the mortar can be easily raised. In addition, the connecting ring 20 is reliably fixed and positioned at the joint between the block blocks by inserting the flange 22 into the joint. Further, since the ring-shaped band-shaped frame portion 21 of the connecting ring 20 also serves as a seal for the joint between the block blocks, by using the connecting ring 20, the joint between the block blocks can be made. The sealing property of is improved. Further, it goes without saying that the above-mentioned joining structure can be applied to the joining portion between the adjusting side block 12 and the adjusting side block 13 and the joining portion between the adjusting side block 13 and the edge block 14. .

Next, referring to FIGS. 4 and 5, the connection ring according to the present invention is replaced with the cylindrical shape of the above-described embodiment, and a concrete slab block is joined to assemble a prismatic concrete stake. Examples for use in Also in this case, the connecting ring 20 'includes a frame portion 21' in which a belt-shaped member is formed in a ring shape and a flange portion 22 'from the outer peripheral surface toward the outer side. Has a square ring shape with an outer shape of "B" in conformity with the shape of the inner peripheral surface of the square-shaped rectangular block. Further, it goes without saying that the cross-sectional shape thereof is a substantially V-shaped cross section, similar to the connecting ring of the above-mentioned embodiment.

In the above-mentioned embodiment of the present invention, only the drainage basin and the sewage basin have been described, but the present invention is not limited to this and can be applied to, for example, a basin of a joint portion of a manhole or the like. It will be apparent to those skilled in the art.

Further, in the above-described embodiment, the flange portions 22 and 22 ′ are formed from the outer peripheral surface of the circular ring-shaped band-shaped frame portions 21 and 21 ′ forming the connecting rings 20 and 20 ′ toward the outside, The projecting angles of the collar portions 22 and 22 'are set upright with respect to the outer peripheral surface. However, particularly when the end faces of the joint portions are inclined, the collar portions 22 and 22' are also preliminarily set. It may be inclined. However, when the protrusion angles of the collar portions 22 and 22 'are set to a right angle, the collar portions 22 and 22' are bent by the weight of the blocks to be overlaid, so that the end face of the joint portion is inclined. It can also be used when the end faces of the joint are parallel.

Further, by arranging the above-mentioned collar portions 22 and 22 ′ substantially in the center of the strip-shaped frame portion 21 in the width direction, and further by projecting the collar portions 22 and 22 ′ at a right angle, this connection The shapes of the rings 20 and 20 'are vertically symmetrical, and the rings 20 and 20' can be used upside down, which is expected to improve workability. As for the material of the connecting rings 20 and 20 ', cast iron can be manufactured at a comparatively low cost, but if stainless steel is used, it is resistant to corrosion and excellent in durability and mechanical strength. In addition, the weight of the connecting ring can be reduced by using aluminum. If the connecting ring is made of a resin such as vinyl chloride, it can be manufactured at a relatively low cost by integral molding such as resin injection molding, and there is no concern about rust or corrosion.
