  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  For example, in a long groove provided on a road or the like, a plurality of snow-dissipating blocks 2 are arranged in a tandem state and abutting surfaces 3 at both ends of each snow-dissipating block 2 are abutted to each other, so that The end portions 1 </ b> A of the water channel 1 are matched to each other and the water spray channels 1 are connected in communication.

  More specifically, in the present invention, the connection between the water sprinkling channels 1 does not use a connecting pipe projecting outward from the abutting surface 3, and one snow-dissipating block 2 in a tandem state is used. On the other hand, the other snow-dissipating block 2 is lowered, and at this time, one of the snow-dissipating blocks 2 is placed by a positioning plate 4 laid between the bottom of one snow-dissipating block 2 and the bottom of the other snow-dissipating block 2. The abutting surfaces 3 of the snow block 2 and the other snow-dissipating block 2 are positioned and held in the abutting state, and between the abutting surfaces 3 of the snow-dissipating blocks 2 held in the abutting state by the positioning plate 4. The water stop elastic member 5 is disposed and fixed so as to surround the end 1A of each water sprinkling channel 1, and the water sprinkling channels 1 are connected to each other in a water stop state.

  Therefore, for example, a positioning plate 4 is laid in advance, and one snow-dissipating block 2 is placed on the positioning plate 4 and then the other snow-dissipating block 2 is placed at an installation position from substantially above. Since the abutting surfaces 3 of the snow-dissipating blocks 2 arranged in a row are positioned and held in a butted state only by being lowered and mounted using a crane or the like, the installation work of the snow-dissipating block 2 is extremely easily performed. become.

  In addition, the snow removal block 2 can be easily placed on the positioning plate 4 and can be stably placed, and the positioning position of the snow removal block 2 is not greatly raised by the positioning plate 4. Therefore, although the positioning plate 4 is laid between the installation location and the snow-melting block 2, the installation work of the snow-melting block 2 is easily performed and the workability is excellent.

  Moreover, also about the water stop structure (connection structure) of the water sprinkling paths 1, it surrounds the edge part 1A of each said water sprinkling path 1 between the abutting surfaces 3 of each snow-melting block 2 hold | maintained in the abutting state. Since the structure is such that the water-stopping elastic material 5 is simply disposed and fixed, the structure can be easily constructed, and the snow-dissipating block 2 is moved laterally to insert and connect the tubes (cylinders). Such a high alignment accuracy is also unnecessary, and the operation of connecting the water sprinkling channels 1 can be performed very easily.

  In addition, when it is necessary to replace a damaged or deteriorated snow-melting block 2 after completion of the snow-melting equipment, a crane or the like is used without cutting the pipe or disassembling the end of the adjacent snow-discharging block 2. Then, it can be removed simply by moving it up, and the new snow-blocking block 2 installed in this removal space can also be lowered and installed without lateral movement. It can be easily exchanged together with the elastic material 5.

  Similarly, the water-stopping elastic material 5 that has been damaged or deteriorated can be easily replaced.

  Further, for example, when the other snow removing block 2 is lowered and mounted on one snow removing block 2, the positioning plate 4 engages with the bottom of the other snow removing block 2 so as to be unevenly engaged. If the snow-melting block 2 is configured to be positioned and held, the snow-melting block 2 can be reliably positioned by uneven engagement, and the uneven engagement structure between the positioning plate 4 and the snow-dissipating block 2 is a simple structure. Therefore, the design can be easily realized.

  Further, for example, as the other snow removal block 2 descends on the concave and convex engagement surface of the positioning plate 4, the abutment surface 3 of the other snow removal block 2 is replaced with the abutment surface 3 of the one snow removal block 2. If a tapered guide surface portion 6 is provided which can be guided and moved in a direction approaching each other to bring the butted surfaces 3 into a butted state, the snow-melting block 2 is lowered to a slightly rough position during installation. However, since it is guided and guided to an appropriate installation position by the concave-convex engagement with the positioning plate 4, the installation workability is further improved.

It is provided in a side-by-side state, and the butt face 3 having a vertical surface is provided at both ends in the longitudinal direction.

  In addition, the snow-dissipating block 2 is provided with a sprinkling channel 1 for supplying ground water or the like to the watering nozzles 7 in a buried state along the longitudinal direction of the snow-dissipating block 2, and both end portions of the sprinkling channel 1. 1A is constructed so as to be adjacent (opened) to each of the butting surfaces 3, but this watering channel 1 is not formed by embedding a pipe or the like in the snow-dissipating block 2, but in this embodiment, the watering channel 1 is formed. The snow-melting block 2 integrally formed with concrete in the shape it has is adopted.

  In addition, as shown in FIG. 3, the snow-dissipating block 2 is integrally provided with engaging recesses 9 for engaging a positioning plate 4 (described later) at the bottom (bottom) of both ends, and each protrusion at both ends. On the mating surface 3, as shown in FIG. 1, a polygon (drawing) that is concentric with the center (axial center) of the sprinkling channel 1 around the end 1 </ b> A of the sprinkling channel 1 and larger in diameter than the sprinkling channel 1. In this case, the concave portion is formed as an accommodation concave portion 10 in which a water-stopping elastic material 5 described later is accommodated.

That is, it is configured such that the bottom surfaces of the end portions of the two snow-dissipating blocks 2 can be placed on the plate surface of the rectangular plate material that constitutes the positioning plate 4 with the butted surfaces 3 attached to each other. Yes.

  Further, the positioning structure of the positioning plate 4 and the end of the snow-fighting block 2 has a cross section in which the opposing two sides of the positioning plate 4 are bent substantially vertically upward as shown in FIGS. The raised portions 4A on the opposite two sides are located along the lower left and right sides of the mounted snow removal block 2 and are displaced in a direction perpendicular to the length direction of the snow removal block 2 It is set as the structure which functions as the guide part 4A to prevent.

  Further, engaging projections 8 are provided on both sides of the upper surface of the positioning plate 4, and the engaging recesses 9 provided on the bottom surface of the snow-fighting block 2 are engaged with the engaging projections 8 to perform positioning. By placing the end of the snow removal block 2 on the plate 4, the snow removal block 2 is positioned and held with respect to the positioning plate 4.

  Further, when the end portions of the two snow extinguishing blocks 2 are placed in contact with each other on the positioning plate 4 and the respective engaging concave portions 9 are engaged with the respective engaging convex portions 8 in an uneven manner, FIG. As shown in FIG. 6, the engagement protrusions provided on the positioning plate 4 so that the two snow-melting blocks 2 are positioned and held in a proximity state in which a gap of about 10 mm is generated between the respective butting surfaces 3. Either one or both of the position of the portion 8 and the position of the engaging recess 9 provided at the bottom of the end portion of the snow extinguishing block 2 are set.

  Further, when the other snow-dissipating block 2 is lowered and mounted on the engaging convex portion 8 of the positioning plate 4 with respect to one snow-dissipating block 2, the other snow-dissipating block 2 is lowered as the other snow-dissipating block 2 descends. A tapered guide surface portion 6 is provided for guiding and guiding the butting surface 3 of the snow-melting block 2 in a direction approaching the butting surface 3 of one snow-melting block 2.

  Specifically, as shown in FIGS. 1, 2, and 6, the engaging convex portion 8 on one side of the positioning plate 4 is formed in a substantially circular shape in plan view, and the engaging convex portion 8 on the other side is a flat surface. The guide surface portion 6 is provided only on the engagement convex portion 8 on the other side.

  More specifically, as shown in FIG. 4, the side surface of the other side engaging convex portion 8 having an oval shape facing the one side engaging convex portion 8 is formed as a tapered surface that is inclined rearward. Is the guide surface portion 6. Note that the shapes of the engaging convex portion 8 having the guide surface portion 6 and the engaging convex portion 8 not having the guide surface portion 6 are made different from each other so that it is easy for the field worker to place the positioning plate 4 in which direction. This is so that it can be confirmed.

  On the other hand, the engagement recesses 9 provided at the bottoms of both ends of the snow-melting block 2 are also formed such that the engagement recess 9 on one side is a recess having a substantially circular cross section and the engagement recess 9 on the other side has a long cross section. The engaging recess 9 on the other side is formed in a circular recess, and a side surface facing the engaging recess 9 on one side is formed as a tapered surface that is inclined rearward, and this tapered surface is the engagement protrusion on the other side. It is configured to engage with the guide surface portion 6 of the portion 8.

  Further, the size of the engagement recess 9 on the other side is set to be slightly larger than the engagement projection 8 on the other side, and the engagement recess 9 on the other side and the engagement projection 8 on the other side are uneven. A gap is formed when engaged, so that the other snow-absorbing block 2 can be moved slightly even during uneven engagement so that the installation position can be finely adjusted.

  In other words, in this embodiment, the snow removal block 2 is not completely corrected to the correct installation position by guidance of the guide surface section 6, but is a configuration that requires final installation position adjustment.

  In this way, the engagement recess 9 on the other side and the engagement projection 8 on the other side are engaged with each other with a gap therebetween, and the guide surface portion 6 does not guide the snow removal block 2 to the correct installation position. For example, when replacing the snow-melting block 2 that has failed after the completion of construction, the snow-removing block 2 to be replaced is lifted substantially directly using a crane or the like to engage with the engaging recess 9 and the engaging protrusion. Since the concave-convex engagement with the portion 8 can be easily disengaged and removed, it is excellent in maintainability.

  The water stop elastic material 5 of the present embodiment is made of rubber and has a circular ring shape larger in diameter than the end portion 1A of the water sprinkling channel 1 as shown in FIG.

  Further, the water-stopping elastic material 5 is a tube structure having a square cross section that expands by injecting air, and the water-stopping elastic material 5 is positioned and held in a butted state by the positioning plate 4. Between the abutment surfaces 3 of the snow block 2, the end portions 1A of the water sprinkling passages 1 are arranged so as to surround them, and the water-stopping elastic material 5 is inflated by injecting air. 3, the water stop elastic material 5 is used to make the water stop state between the end portions 1 </ b> A of the water sprinkling channels 1.

  Further, the outer diameter of the water-stopping elastic material 5 and the housing recess 10 is such that the water-stopping elastic material 5 can be housed in the housing recess 10 of the abutting surface 3 and temporarily held. Is configured. Accordingly, it is possible to temporarily fix the water stop elastic material 5 in the housing recess 10 of one snow squeeze block 2 that has been installed until the other snow squeeze block 2 that is subsequently lowered and placed is completed. Therefore, the construction work can be performed very easily and efficiently.

  Further, the water-stopping elastic material 5 includes an injection portion 5A for injecting air, and after positioning one snow-dissipating block 2 and the other snow-dissipating block 2 in a butted state, the injecting portion 5A The water-stopping elastic material 5 can be expanded by injecting air.

The protruding injection portion 5A is accommodated and exposed to the outside of the snow-melting block 2, and air can be injected from the injection portion 5A exposed to the outside of the snow-melting block 2 through the groove portion 14.

  In the present embodiment, the water-stopping elastic material 5 expanded by air injection is bonded to the butt surface 3.

  Specifically, the adhesive 13 is applied in advance to both side surfaces of the water-stopping elastic material 5, and when the water-stopping elastic material 5 expands by air injection, the both side surfaces thereof are the butted surfaces 3 (accommodating recesses). 10), and the pressure contact (adhesion) state is maintained by the curing of the adhesive 13, thereby exhibiting reliable water stoppage.

  Next, the construction procedure of a present Example is demonstrated.

  The positioning plate 4 is placed at a predetermined position of the installation place, and one snow-dissipating block 2 is placed on one side of the positioning plate 4 and is engaged with the concave and convex portions, so that it is placed in the receiving recess 10 of the one snow-dissipating block 2. The elastic material 5 for water stop is temporarily fixed and accommodated, and then the other snow-dissipating block 2 is placed on the other side of the positioning plate 4 to be engaged with the concave and convex portions, so that the butting surfaces 3 of the two snow-dissipating blocks 2 are formed. The elastic material 5 for water stop is disposed between the butted surfaces 3.

  Specifically, for example, a positioning plate 4 is laid in advance in a long groove (installation place) provided on a road or the like, and a snow extinguishing block is formed on a substantially regular circular engaging convex portion 8 on one side of the positioning plate 4. The snow-removing block 2 is placed by engaging a concave-convex engaging recess 9 having a substantially circular cross section on one side of 2 and bonded to the receiving recess 10 of the butting surface 3 of the snow-removing block 2 on both sides. The ring-shaped elastic material 5 for water stop to which the agent 13 is attached is temporarily stored.

  Subsequently, while lowering the other snow-melting block 2 with respect to one installed snow-melting block 2, the other snow-dissipating block 2 is moved to the oval engagement convex portion 8 on the other side of the positioning plate 4. When the engagement concave portion 9 having an elliptical cross section on the other side of the bottom of the end portion is engaged, the guide surface portion 6 of the engagement convex portion 8 and the taper surface of the engagement concave portion 9 are engaged with each other. The other snow-dissipating block 2 descends while being guided and guided so as to approach the other snow-dissipating block 2 (see FIG. 4). Is brought into a close-abutting state, and in this state, both the snow-absorbing blocks 2 are positioned and held (see FIGS. 5 and 6).

  Subsequently, when air is injected into the elastic material 5 for water stop and inflated so that both side surfaces are pressed against the receiving recesses 10 of the respective butting surfaces 3, the adhesive 13 is cured and fixed, and both snow-squeezing blocks 2 are fixed. Each water sprinkling channel 1 is connected in a sealed water-stopped state by a water-stopping elastic material 5.

  This operation is repeated to complete a desired snow-melting facility.

  In addition, when it is necessary to replace the deteriorated snow removal block 2 after the completion of the snow removal facility according to the present embodiment, only the snow removal block 2 to be replaced is raised almost directly using a crane or the like. It can be removed by moving it, and a new snow-dissipating block 2 can be lowered and placed together with the water-stopping elastic material 5 at the place of removal. Similarly, it is easy to replace only the water-stopping elastic material 5.

  In the figure, reference numeral 11 denotes a joint material disposed in the gap between the butting surfaces 3 of the snow-melting blocks 2 in a tandem state.

  In the present embodiment, a case where a plurality of snow-melting blocks 2 are connected in a straight tandem state is shown. However, the snow-breaking blocks 2 are curved (bent) using elastic deformation of the water-stopping elastic material 5. It can be connected in a vertical state, or it can be bent in the vertical direction according to the undulations of the installation location and connected in a vertical state. Further, the elastic position of the water-stopping elastic member 5 is elastically deformed, so that fine adjustment of the installation position of the snow-melting block 2 is also possible.

  The positioning plate 4 is not limited to metal, but may be made of rubber, chemical fiber, resin, or other material. Further, the positioning operation may be improved by further increasing the height of the rising portion 4A of the positioning plate 4, or the rising portion 4A may be omitted. Moreover, the shape of the engaging convex part 8 of the positioning plate 4 is not limited to a circle or an oval, but may be a square or another shape.

  Further, the water-stopping elastic material 5 is not limited to rubber, but may be made of sponge, urethane, or other elastically deformable material. Further, the shape of the water stop elastic material 5 is not limited to the circular ring shape, but may be a rectangular shape, a polygonal shape, or the like. Moreover, the cross-sectional shape of the water-stopping elastic material 5 is not limited to a square, and may be a circle. Further, the water-stopping elastic material 5 may not be a tube structure, and may not be bonded to the butting surface 3.

  A second embodiment of the present invention will be described with reference to FIG.

  In this embodiment, the auxiliary metal fitting 12 for positioning the water stop elastic material 5 is provided in the housing recess 10 of the butting surface 3 of the snow-melting block 2 in the first embodiment.

  Specifically, the auxiliary metal fitting 12 is constituted by a circular ring-shaped metal fitting that is slightly smaller in diameter than the inner diameter of the circular ring-shaped water-stopping elastic member 5, and the ring-shaped auxiliary metal fitting 12 is formed at the center of the sprinkling channel 1. A concentric position is provided so as to project from the housing recess 10.

  Accordingly, the auxiliary metal fitting 12 protruding in the shape of a circular ring is configured to be able to be accommodated in the accommodating recess 10 so as to be hooked with the water-stopping elastic material 5 before the air is injected, so that water can be stopped in the accommodating recess 10. The temporarily fixed state of the elastic material 5 is made more stable.

  Other configurations are the same as those of the first embodiment.

  A specific third embodiment of the present invention will be described with reference to FIGS.
