Description

The present invention relates to a structural block such as a road paving block or a building surface decoration block, and more specifically, a structure having a function of cooling the vicinity of the surface of a structure such as a sidewalk, a plaza or a building. The present invention relates to a connection structure for object blocks.

  Various techniques have been proposed in the past for reducing the heat of pedestrians and the like by lowering the temperature of a surface such as a sidewalk whose temperature rises due to solar heat in summer and suppressing the radiant heat from the surface. For example, the block pavement structure described in Patent Document 1 has a plurality of through holes 51a in the peripheral wall between side surfaces of a porous pavement block 50 having water permeability, as shown in FIG. It is the structure by which the water guide pipe 51 by which this was wound was arrange | positioned. Then, water is permeated into the paving block 50 through the nonwoven fabric 52 from the through hole 51 a of the water conduit 51. And water is vaporized on the surface of the paving block, and the temperature of the paving block 50 is lowered by the heat of vaporization.

In the cooling device described in Patent Document 2, as shown in FIG. 14, a water supply pipe 61 embedded in a road 60 includes a nozzle 62, and water is sprayed or sprayed on the surface side of the road 60 through the nozzle 62. . Thereby, the temperature near the surface of the road 60 is lowered by the heat of vaporization of water.
JP 2004-169285 A JP-A-6-159886

  However, the block pavement structure described in Patent Document 1 is configured to permeate the water flowing out from the water conduit 51 to the surface layer portion of the pavement block 50 by a capillary phenomenon, so that an amount of water necessary for cooling is paved. May not be supplied to the surface layer of the block 50 for use. Therefore, in such a case, when the temperature is excessively high, the cooling capacity for the vicinity of the road surface is insufficient. Also, when the cooling is unnecessary, the paving block 50 is infiltrated and the water is vaporized, so that the pedestrian may be uncomfortable when the temperature is low. Furthermore, since the wet state of the paving block 50 is often prolonged by rainwater, bacteria are likely to grow on the surface and moss is likely to grow, thereby giving an unclean appearance and an appearance that tends to be poor. In addition, since the paving block 50 is porous, its strength is low, and in particular, there is a risk of destruction when water such as rainwater that has penetrated into the slits freezes.

  In the cooling device described in Patent Document 2, when a large area on the road surface is to be uniformly cooled, a large number of water supply pipes 61 must be embedded in the ground and a large number of nozzles 62 must be branched. However, it takes time and time for construction, and requires a long construction period. Therefore, it is difficult to uniformly cool the entire surface of a large area. Moreover, in order to protect the water pipe 61 embedded in the ground from the load applied to the road surface, it is necessary to bury the water pipe 61 in a deep position in the ground, which requires much more work.

The present invention has been made paying attention to such problems existing in the prior art. Its purpose is to provide a structure block connection structure that can cool the surface area of the required area of the structure uniformly and effectively, and has the advantage of being easy to construct and having excellent strength. There is to do.

In order to achieve the above-mentioned object, the invention according to claim 1 is a structure for connecting structural blocks , which are installed in close contact with each other on a structure and form a surface of the structure. The water conduit forming member is embedded in the main body of the structural block, and the end opening of the water conduit forming member reaches the surface of the main body at the center of the side surface of the main body and opens to the surface. The water supply portion that is located in the concave portion formed as described above and opens to the surface of the main body portion is branched from the water conduit forming member, and the end openings facing each other between the adjacent main body portions are joints. And a hole formed by the concave portion between the side surfaces of the two adjacent main body portions is closed with a lid .

The invention according to claim 2 is characterized in that the water conduit forming member is constituted by a plurality of water conduits connected to each other.
According to a third aspect of the present invention, the water conduits are connected to each other at the central portion of the main body and are arranged radially from the central portion toward the side surfaces. It is characterized by being branched from the connecting portion.

(Function)
In this invention, if it installs in the surface of a structure in the state which made the several block adjoin, the water conduit forming member of both adjacent blocks will connect and the water conduit which crosses a plurality of blocks will be formed. When water is supplied to the water conduit, water is ejected from the water supply portion of each block to the upper surface of the block. As a result, water is vaporized near the surface of the structure formed by the blocks, and the vicinity of the surface of the structure is cooled by the heat of vaporization. Therefore, it is possible to uniformly cool the entire range of a certain area where the blocks are installed on the surface of the structure. Further, since the water in the water conduit is directly ejected to the outside of the surface of the block, a sufficient amount of water can be supplied to the surface of the block, and the surface of the structure can be effectively cooled. And since a water conduit which connects each block is formed only by connecting a water conduit formation member with a joint adjacent to a block, construction becomes easy. In addition, since the nozzle and the water conduit forming member are embedded in the main body, the load applied to the road surface is not directly applied to them, and the strength of the nozzle and the water conduit forming member is improved.

  According to this invention, the surface vicinity of the required area in the structure can be cooled uniformly and effectively, and the effects such as simple construction and excellent strength are exhibited.

Next, an embodiment in which the present invention is embodied in a paving block will be described with reference to FIGS.
As shown in FIG. 1, paving blocks (hereinafter abbreviated as blocks) 10 are installed in close contact with each other on a roadbed such as a sidewalk or a plaza (not shown). As shown in FIG. 2, the block 10 has a water channel forming member 12 made of metal or hard synthetic resin embedded in a plate-like main body 11 made of concrete, brick, or the like. The water conduit forming member 12 includes four water conduits 13 connected to each other at the center of the main body 11. And the edge part opening of these water conduits 13 is located in the recessed part 11b formed in the center part of each side surface 11a of the main-body part 11, respectively. The upper end of the recess 11b reaches the surface 11c of the main body 11 and opens upward. Each water conduit 13 extends radially from the connecting portion 14 located at the center of the main body 11 so as to be orthogonal to each side surface 11 a of the main body 11. The water conduit forming member 12 has a water supply pipe 15 that branches upward from the connecting portion 14 of the water conduit 13 toward the surface 11 c side of the main body 11.

  As shown to Fig.3 (a), (b), the water supply pipe 15 is comprised by attaching the nozzle 17 to the opening side edge part. The nozzle 17 is detachably mounted on the water supply pipe 15 by screwing a male screw part 17a formed on the outer periphery thereof with a female screw part 15a formed on the inner periphery of the opening side end of the water supply pipe 15. Has been. The nozzle 17 includes a plurality of ejection holes 18 for ejecting water from the water supply pipe 15. A plurality of types of nozzles 17 having different diameters of the ejection holes 18 are prepared. That is, a nozzle 17 having a small-diameter ejection hole 18 for ejecting water from the water supply pipe 15 as a dry mist having a small particle diameter, and an ejection hole having a slightly larger diameter for ejecting water as a mist having a large particle diameter. A nozzle 17 having a nozzle 18 and a nozzle 17 having a large-diameter ejection hole 18 for ejecting water in a shower-like manner. A pair of holes 17b for a tool used for rotating the nozzle 17 when the nozzle 17 is attached to and detached from the water supply pipe 15 are formed on the surface side of the nozzle 17.

  As shown in FIG. 2, the end opening of the water conduit 13 is provided with a connecting portion 20 for connection with the end opening of the water conduit forming member 12 of the adjacent block 10, as shown in FIG. A female screw portion 20a is formed on the inner periphery thereof. Each female screw portion 20a has a spiral direction opposite to the female screw portion 20a of the other adjacent connecting portion 20. Marks 11d and 11e indicating the spiral direction of the female screw portion 20a are attached to the bottom of the concave portion 11b.

  As shown in FIGS. 1 and 4, between the adjacent blocks 10, the connecting portions 20 that open to the concave portions 11 b facing each other are connected to each other by joints 23 connected to the respective connecting portions 20. Yes. As shown in FIG. 5A, the joint 23 is provided on both sides of the outer peripheral hexagonal fastening portion 24 and the female screw portion 20a of each connection portion 20 provided on both sides of the fastening portion 24. And a male screw portion 25. The spiral directions of both male screw portions 25 are opposite to each other. Marks 25 a and 25 b are formed on the tightening portion 24 of the joint 23 to indicate the identification of the male screw portion 25 in the spiral direction. And the joint 23 connects the water conduit formation members 12 in a watertight state by screwing both the male screw parts 25 to the female screw part 20a of the connection part 20, respectively.

  As shown in FIG. 4, a spanner insertion hole 26 for turning the tightening portion 24 of the joint 23 from the outside (upper portion) with a spanner is formed by a pair of concave portions 11b facing each other between the adjacent blocks 10. After the spanner operation is completed, the upper surface opening of the spanner insertion hole 26 is closed by a synthetic resin or metal lid 27 as shown in FIGS. 4 and 6A, 6B, and the joint 23 or spanner. The insertion hole 26 is concealed. As shown in FIG. 4, a step 11f is formed at the upper end opening of each recess 11b constituting the spanner insertion hole 26, the lid 27 is placed on the step 11f, and the upper surface of the lid 27 is The upper surface of the block 10 is located on the same plane. As shown in FIGS. 1, 4, 6 (a) and 6 (b), the lid 27 has a notch 27 a for a tool when the lid 27 is removed from the spanner insertion hole 26, and the spanner insertion hole 26. And an insertion portion 27b for firmly fixing to.

  Therefore, as shown in FIGS. 4 and 7, the water conduit 13 that opens to the recess 11 b of each side surface 11 a of the block 10 is in contrast to the water conduit 13 that opens to the recess 11 b of the adjacent block 10 that is in close contact with the side surface 11 a. To each other via a joint 23. As a result, as a whole, a grid-shaped waterway having a nozzle 17 for each block 10 is formed inside the block 10 group on which the road pavement surface is formed.

  As shown in FIG. 1, in order to connect a water supply pipe (not shown) from the outside to the connection part 20 of the block 10 that receives the supply of water from the outside among the blocks 10 arranged at the outer edge in the group of blocks 10. A joint 23 is attached to the. On the other hand, among the blocks 10 arranged at the outer edge in the group of blocks 10, the connection portion 20 of the block 10 that does not receive the supply of water from the outside is as shown in FIGS. 4, 5 </ b> B, and 5 </ b> C. A stopper 28 is attached. The plug 28 includes a male screw portion 28a that is screwed into the female screw portion 20a of the connection portion 20, and an outer peripheral hexagonal fastening portion 28b that is integrated with the male screw portion 28a. The plug 28 is provided with a male screw portion 28a having a spiral direction in the right direction and a left direction, and marks 29a and 29b for identifying both are attached to the respective tightening portions 28b. Yes. The plug 28 is configured to seal the connection portion 20 by screwing the male screw portion 28a with the female screw portion 20a of the connection portion 20.

  Now, the block 10 configured as described above is laid in close contact on a roadbed such as a sidewalk or a square as shown in FIG. Here, the positional relationship between the two blocks 10 is matched so that the spiral directions of the female screw portions 20a of the two connecting portions 20 facing each other in the adjacent blocks 10 are opposite to each other. Then, the connecting portions 20 facing each other are connected by the joint 23. The screwing of the male threaded portion 25 of the joint 23 to the female threaded portion 20a of the both connecting portions 20 causes the tightening portion 24 of the joint 23 to be rotated by the spanner in the spanner insertion hole 26 formed between the blocks 10. Do that. At this time, since the male screw portions 25 on both sides of the tightening portion 24 are reverse screws, the adjacent blocks 10 are moved in the approaching direction as the male screw portion 25 and the female screw portion 20a are screwed together. Thus, the side surfaces 11a come into contact with each other. After laying the block 10 in a desired range on the roadbed in this manner, the water jet pressure from each jet hole 18 is applied to an appropriate connection portion 20 located at the periphery of the entire laid block 10. A pipe line for supplying water from a pump (not shown) is connected to the connection part 20 selected to be uniform. Further, the remaining connecting portion 20 located at the peripheral edge is closed by the plug 28. Thus, the laying of the block 10 is completed.

When high pressure water is supplied from the pump to the block 10 group laid on the roadbed in this way, this water forms a water conduit for each block 10 through the water conduit 13 communicated between the adjacent blocks 10. It is supplied into the member 12. Then, in each block 10, water is ejected from the nozzle 17 above the surface of the block 10. here,
When the ejection hole 18 of the nozzle 17 has a small diameter, the ejected water becomes a mist, and when the ejection hole 18 has a large diameter, the ejected water has a shower shape. Accordingly, the mist is vaporized on the surface of the block 10, and the heat of vaporization cools the block 10 and the air near the surface of the block 10. Further, the shower-like water is sprinkled in the form of water to be used for cooling the block 10 and its surroundings. As a result, the radiant heat from the block 10 is reduced. In addition, when the said mist is a dry mist with a small particle size, a pedestrian's skirt etc. are not wetted.

According to this embodiment, the following effects can be obtained.
(1) Water is sprayed or sprinkled from the laid block 10 through the nozzle 17, and the entire range where the block 10 is laid can be cooled substantially uniformly. Moreover, since the water in the water conduit 13 is directly sprayed upward from the surface from each nozzle 17, a sufficient amount of water can be supplied above the surface of the block 10, and the vicinity of the surface of the block 10 is effectively cooled. be able to.

  (2) When it is not necessary to make the main body 11 of the block 10 porous, and cooling is unnecessary, the surface 11c of the block 10 is quickly dried by stopping the supply of water to the water conduit forming member 12. Can do. Therefore, unlike the paving block 50 of Patent Document 1, it prevents unnecessary wetting and prevents discomfort due to vaporization of water when it is unnecessary, and the appearance of bacteria and moss is prevented. it can.

  (3) By selecting the nozzle 17 connected to the water supply pipe 15, the size of the ejection hole 18 can be set in accordance with the purpose, and the type of mist spraying, watering, etc. can be carried out freely.

(4) Since the main body 11 is not porous as described above, unlike the paving block 50 of Patent Document 1, it has high strength and can prevent breakage due to freezing.
(5) The main body 11 of the block 10 is reinforced by the embedded cross-shaped water conduit forming member 12 to improve its strength.

  (6) Since the nozzle 17 and the water conduit forming member 12 are embedded in the main body 11, the load applied to the surface of the road surface is prevented from being directly applied to them. For this reason, unlike the water pipe 61 of patent document 2, in order to ensure load resistance, it is not necessary to embed in the deep position in the ground, and construction becomes easy.

  (7) The water conduit forming member 12 of each block 10 communicates with each water conduit forming member 12 of the eight adjacent blocks 10. For this reason, by selecting the connecting portion 20 to which the pressure water is supplied, the water supplied from the outside to each water conduit forming member 12 of the group of blocks 10 is ejected from the nozzles 17 of each block 10 with an equal pressure. It becomes possible.

  (8) Since the water conduits connecting the blocks 10 are formed simply by connecting the water conduit forming members 12 with the joints 23 with the blocks 10 next to each other, piping work becomes unnecessary, construction is easy, and the construction period is shortened. Can do. In addition, the joint 23 having a pair of male screw portions 25 having different spiral directions is used, and each male screw portion 25 is screwed into the female screw portion 20a of the connecting portion 20 of the adjacent block 10. For this reason, only by turning the joint 23, the adjacent blocks 10 can be easily moved close to each other by the action of screws, and the laying of the blocks 10 can be easily performed.

In addition, this embodiment can also be changed and embodied as follows.
