Description

  The present invention relates to a non-sprinkling snow melting block for pavement that melts snow by heat, and is formed in a predetermined shape with respect to a heat radiating pipe that is buried in the block and circulates groundwater or the like to heat the block. This relates to a jig for use.

  In heavy snowfall areas, there are various facilities that melt snow on the road surface. For example, a snow removal block that melts snow with a watering nozzle is well known. The snow-blocking block is embedded in the road surface so that its surface is exposed. Water spray nozzles are provided on the surface at predetermined intervals, and piping for supplying water to these water spray nozzles is provided for the snow-blocking block. Embedded in. Therefore, when hot water such as groundwater is supplied from the pipe, water is sprayed from the watering nozzle and the snow on the road surface is melted. Snow-melting blocks are applied to many roadways because snow is efficiently melted by groundwater that is sprinkled.

  On the other hand, paving blocks that melt snow without watering are also well known. Such a paving block is called a non-sprinkling snow melting block and is laid on the road surface. For example, as proposed in Patent Document 1, a non-watering snow melting block is embedded with a heat radiating pipe bent into a predetermined shape. By supplying hot water to the heat radiating pipe, the entire block is uniformly heated, and the snow accumulated on the block is melted by the heat. As hot water supplied to the heat radiating pipe, for example, as described in Patent Document 2, groundwater is often used. The groundwater is pumped up, circulated through the radiator pipe, warms the non-sprinkling snowmelt block, and then returned to the basement again. Such a non-sprinkling snow melting block is suitable for a sidewalk without splashing pedestrians because it is not sprinkled. In addition, groundwater is returned to the ground, so there is no problem of groundwater depletion.

  The non-sprinkling snow melting block is made of reinforced concrete, and the heat radiating pipe is embedded as described above. The radiator pipe is bent and reciprocated multiple times in the block so that the non-sprinkling snow melting block can be heated efficiently, so that the distance between adjacent radiator pipes is constant so that the entire block can be uniformly heated. Is formed. The heat radiating tube can be formed of a metal tube such as an aluminum tube, or can be formed of a flexible resin tube such as a vinyl chloride tube, and the material can be selected as appropriate. However, there is a problem that it is difficult to form the heat radiating tube in a desired shape regardless of whether it is a metal tube or a resin tube. For example, in the case of a metal tube, bending it to a desired shape requires skill and requires a long working time. If it does so, the cost of a non-watering snow melting block will become large. On the other hand, in the case of a resin tube, it can be easily bent at an arbitrary location, but there is a problem that it is difficult to maintain a predetermined shape. Such a radiant pipe is fixed to a grid-like reinforcing bar embedded in a non-sprinkling snow-melting block by binding wires so that the shape does not collapse when concrete is placed, but the resin pipe maintains its shape. Since it is difficult to achieve this, it is difficult to fix the cable with a binding wire. That is, even in the case of a resin pipe, the workability is poor, and the cost of the non-watering snow melting block is also increased. There is also a problem that the shape of the heat radiating tube becomes uneven. Even if it is a metal tube or a resin tube, if it is made to bend with a certain amount, the interval between adjacent heat radiating tubes will be uneven. If it does so, the problem that the whole block cannot be heated uniformly will arise.

  An object of the present invention is to provide a forming jig for forming a heat radiating pipe embedded in a non-sprinkling snow melting block, which solves the above-described conventional problems. Specifically, the heat radiating pipe is a metal pipe. It can be efficiently formed into a desired shape regardless of whether it is constructed from a resin tube or a resin tube, and a uniform shape can be stably formed, thereby reducing the cost of the non-sprinkling snow melting block. An object of the present invention is to provide a jig for forming a heat radiating tube.

  In order to achieve the above object, the present invention forms a heat-radiating pipe embedded in a non-sprinkling snow melting block laid on a road and configured to warm the non-sprinkling snow melting block by flowing hot water into a predetermined shape. It is comprised as a jig for forming a heat radiating tube. The radiating tube forming jig is composed of a base and a plurality of holders fixed on the base. The plurality of holders are arranged at predetermined intervals along the shape of the heat radiating tube so that the heat radiating tube can be fixedly held and removed. The height of the base is 70 to 110 cm, and the base is configured to be rotatable about a vertical axis passing through the approximate center of the base.

That is, in the invention described in claim 1, a heat radiating pipe through which hot water flows is formed in a predetermined shape, the heat radiating pipe is fixed to a lattice-shaped reinforcing bar, and the heat radiating pipe and the reinforcing bar are placed in a mold. And, for non-sprinkling snow melting blocks laid on the road, which are manufactured by placing concrete, when manufacturing the non-sprinkling snow melting blocks, the heat radiating pipe is in a predetermined shape and fixed to the rebar a heat radiating pipe for forming jig, the heat radiation tube forming jig is composed of a base, a plurality of holders which are fixed on the base board, the plurality of holder, a predetermined The upper portion is open and is arranged at predetermined intervals along the shape of the heat radiating tube. When the heat radiating tube is formed in the predetermined shape, the heat radiating tube is pushed in from above and fixed. And the heat radiating pipe is The fact that so remove the radiator tube after securing the configured as a heat pipe forming jig according to claim.
According to a second aspect of the present invention, in the radiator tube forming jig according to the first aspect , the base is selected at a height of 70 to 110 cm from the ground. Configured as a tool.
According to a third aspect of the present invention, in the jig for forming a heat radiating tube according to the first or second aspect, the base is rotatable about a vertical axis passing through a substantially center of the base. It is configured as a heat radiation tube forming jig.
According to a fourth aspect of the present invention, there is provided a heat radiating pipe comprising the heat radiating pipe forming jig according to any one of the first to third aspects and a material pipe supply device that feeds out a material pipe as a material of the heat radiating pipe. In the manufacturing apparatus, the material tube supply device includes a turntable on which a material tube wound in a coil shape is placed while rotating about a vertical axis, and the turntable rotates to rotate the material tube. A material pipe is fed out and guided to the heat radiating pipe forming jig, thereby constituting a heat radiating pipe manufacturing apparatus.

As described above, according to the present invention, the heat dissipating pipe for flowing hot water is formed in a predetermined shape, the heat dissipating pipe is fixed to a lattice-shaped reinforcing bar, and the heat dissipating pipe and the reinforcing bar are placed in a mold, and For non-sprinkling snow melting blocks laid on the road, which are manufactured by placing concrete, when manufacturing non-sprinkling snow melting blocks, a heat dissipation pipe is formed in a state where the heat dissipation pipe is in a predetermined shape and fixed to the rebar. It is configured as a jig. The jig for forming a heat radiating tube is composed of a base and a plurality of holders fixed on the base, and the plurality of holders are of a predetermined length and open at the top, It is arranged at predetermined intervals along the shape of the tube, and when the heat radiating tube is formed in a predetermined shape, the heat radiating tube is pushed in from above and fixed, and the heat radiating tube is fixed to the reinforcing bar after the heat radiating tube is fixed. It is configured to be removed . That is , when forming the heat radiating tube from the metal tube, the heat radiating tube can be easily formed by bending the metal tube in accordance with the position of the holder and fixing the metal tube to the holder. Further, when the heat radiating tube is formed from the resin tube, the heat radiating tube is naturally formed in a predetermined shape if the resin tubes are sequentially fixed to the plurality of holders. Although it explains in detail by the form for inventing, even when forming a radiating tube from a metal tube, or when forming a radiating tube from a resin tube, on the radiating tube fixed to the holder of a jig. If a grid-like reinforcing bar is placed, the heat radiating tube can be easily fixed to the grid-like reinforcing bar by a binding wire. When the heat radiating tube is fixed to the grid-like reinforcing bar, the heat radiating tube may be removed from the plurality of holders, that is, the heat radiating tube forming jig. Thus, the radiator tube forming jig of the present invention can form the radiator tube easily and efficiently. Therefore, the non-watering snow melting block can be manufactured at a low cost. In addition, since the shape of the heat radiating pipe obtained by the jig for forming the heat radiating pipe is adjusted by a plurality of holders, a heat radiating pipe having a uniform quality and high quality can be obtained. Thereby, the non-sprinkling snow melting block can be warmed uniformly. According to another invention, the base is selected at a height of 70-110 cm from the ground . This height is the height in the vicinity of the operator's waist when the operator forms the heat radiating tube. If it does so, the effect that an operator can work easily and can be obtained easily will be acquired. According to another invention, the base is rotatable about a vertical axis passing through the approximate center of the base. A material tube, which is a material of the heat radiating tube, is wound in a coil shape, and is placed on a predetermined table so that the material tube is drawn out. That is, the material tube is drawn out from the fixed direction. When forming a heat radiation pipe having a complicated shape from such a material pipe, when the material pipe is bent in a predetermined direction, the material pipe may be displaced from the direction in which the material pipe is pulled out. However, according to the present invention, since the base rotates, the base can be rotated in accordance with the direction in which the material pipe is pulled out, and the workability is high. According to still another invention, it is configured as a heat radiating pipe manufacturing apparatus including a heat radiating pipe forming jig and a material pipe supply device that feeds out a material pipe as a material of the heat radiating pipe. The material pipe supply device includes a turntable on which a material pipe wound in a coil shape is placed while rotating about a vertical axis, and the turntable is rotated so that the material pipe is fed out and the heat radiating pipe. It is guided by the forming jig. Then, since the material pipe is smoothly supplied and guided to the jig for forming the heat radiating pipe, the workability is further improved, and the cost of the heat radiating pipe, that is, the cost of the non-sprinkling snow melting block can be reduced.

  Embodiments of the present invention will be described below. A heat radiating pipe manufacturing apparatus 1 according to the present embodiment is an apparatus that forms a heat radiating pipe embedded in a non-sprinkling snow melting block. In the present embodiment, the non-watering snow melting block is a reinforced concrete paving block having a square top surface shape and a predetermined thickness. A heat radiating pipe embedded in such a non-sprinkling snow melting block is a heat radiating pipe manufacturing apparatus comprising a heat radiating pipe forming jig 2 and a material pipe supplying device 3 shown in FIGS. 1 is manufactured, that is, formed.

  The radiating tube forming jig 2 according to the present embodiment includes a plate-like base 5 and a plurality of holders 7 fixed on the base 5. As shown in FIG. 2A, the holder 7 has a predetermined length and is open at the top. The width of the opened portion is narrower than the diameter of the material tube 10 that is the material of the heat radiating tube. However, since the holder 7 is made of an elastic material, when the material tube 10 is pushed in from above the opening, the opening is expanded and the material tube 10 is held in the holder 7 as shown in FIG. In other words, it will be fixed. As shown in FIG. 1A, the plurality of holders 7, 7,... Are fixed to the base 5 in a predetermined arrangement. This arrangement is an arrangement fixed at a predetermined interval along the shape of the heat radiating tube to be formed. As a result, when the material tube 10 is sequentially fixed to the holders 7, 7,... While being bent at a predetermined position, a heat radiating tube having a predetermined shape is naturally formed.

  In the radiating tube forming jig 2 configured as described above, the base 5 is placed on the installation base 8 having a predetermined height. Accordingly, in the heat radiating tube forming jig 2 according to the present embodiment, the height of the base 5 is 70 to 110 cm from the ground. This height corresponds to the height near the operator's waist when the heat sink is formed, so that it is not necessary to bend down, it is possible to work comfortably and the arm strength can be used efficiently, and the work efficiency is high. It has become. Furthermore, the base 5 is rotatable on the installation base 8 around a vertical line passing through the substantial center thereof. This makes it possible to work with higher working efficiency when forming the heat radiating tube.

  The material tube supply device 3 according to the present embodiment is a device that can place the material tube 10 wound in a coil shape and can smoothly pull out the material tube 10. The material pipe supply device 3 includes an installation table 12 and a rotary table 13 that rotates on the installation table 12. Guide rods 14, 14,... Are provided vertically on the turntable 13, and the material tube 10 is wound around the guide rods 14, 14,. Therefore, when the material tube 10 is pulled out, the turntable 13 rotates and is pulled out smoothly. By the way, in this Embodiment, the height of such a turntable 13 is the same height as the base 5 of the radiating tube forming jig 2. As a result, the drawn material tube 10 is supplied to the heat radiating tube forming jig 2 at the same height.

  A method of forming a heat radiating tube by the heat radiating tube manufacturing apparatus 1 according to the present embodiment will be described. As shown in FIG. 3, the material tube 10 bundled in a coil shape is placed on the turntable 13 of the material tube supply device 3, and the material tube 10 is pulled out to the radiating tube forming jig 2. The material tube 10 may be a metal tube or a resin tube, but since the turntable 13 is rotatable, the material tube 10 is drawn out smoothly. The worker S works while standing on the side of the heat radiating tube forming jig 2, specifically on the side opposite to the material tube supply device 3. Then, the base 5 of the heat radiating tube forming jig 2 is positioned in the vicinity of the waist of the worker S. The operator S holds the material tube 10 by hand, and gradually pulls it out from the material tube supply device 3 to bend it at a predetermined position as appropriate, and sequentially places it on the plurality of holders 7, 7,. Fix it. When the material tube 10 is bent and fixed to all the holders 7, 7,..., The heat radiating tube 16 is automatically formed. FIG. 4 shows the heat radiating tube 16 fixed to the holders 7, 7,... On the heat radiating tube forming jig 2 in this way.

  When the heat radiating tube 16 is formed, a grid-like reinforcing bar 17 is placed thereon as shown in FIG. 5 while being fixed to the holders 7, 7,. Since the heat dissipating pipe 16 overlaps with a plurality of main reinforcing bars 17a, 17a constituting the lattice-like reinforcing bar 17 and a plurality of reinforcing bars 17b, 17b,... At various points, The heat radiating tube 16 is fixed to the grid-like reinforcing bar 17. As a result, even if the heat radiating pipe 16 is made of a material pipe 10 having high flexibility, for example, a vinyl chloride pipe, the shape of the heat radiating pipe 16 is fixed to the lattice-shaped reinforcing bar 17 without collapsing.

  The heat radiating pipe 16 is removed from the holders 7, 7,..., And the lattice-shaped reinforcing bars 17 and the heat radiating pipe 16 fixed to the lattice-shaped reinforcing bars 17 are removed from the heat radiating pipe forming jig 2. This state is shown in FIG. The lattice-shaped reinforcing bars 17 and the heat radiating pipes 16 are placed in a predetermined formwork, and concrete is placed. When the formwork is removed after the concrete 18 is solidified, a non-watering snow melting block 20 as shown in FIGS. 7A and 7A is obtained. The non-sprinkling snow melting block 20 is laid on the roadbed like the conventional non-sprinkling snow melting block. When warm water such as groundwater is passed through the heat radiating pipe 16, the non-sprinkling snow melting block 20 is warmed and the snow accumulated thereon can be melted.

  The radiator pipe manufacturing apparatus 1 according to the present embodiment can be variously modified. For example, although the radiation pipe forming jig 2 has been described as being configured from the base 5 having a plate shape, it may be configured from the base 5 having a trapezoidal shape. The surface of the base 5 may be formed of a smooth flat surface, or may be formed in a lattice shape like a pallet for logistics. In any case, it is sufficient that the holders 7, 7,... Can be fixed in a predetermined arrangement. Moreover, the shape of the heat radiating tube 16 is not necessarily limited to the shape described in FIGS. 4 to 7, and any shape may be used as long as the non-sprinkling snow melting block 20 can be appropriately heated. . Therefore, in this case, the arrangement of the holders 7, 7,... Is not an arrangement as shown in FIG. As for the shape of the paving block, the shape of the top surface does not have to be square, and in the case of other shapes such as a rectangle, the arrangement of the holders 7, 7,.
