Reinforcing bar cage.

  In heavy snowfall areas, snow-blocking blocks equipped with watering nozzles are buried in the road surface, and ground water is sprayed from the watering nozzles when snow accumulates so that the snow on the road surface is melted. As proposed in Patent Document 1, snow-dissipating blocks have been proposed in various documents, but are configured as shown in FIG. 2, for example. The snow-melting block 50 has a trapezoidal shape in cross-section, but is generally composed of a block having an elongated and substantially rectangular parallelepiped shape. The short side of the two sides of the snow-melting block 50 is 30 to 40 cm, and the length of the long side is, for example, 5 to 10 m. In FIG. 2, the upper surface 51 is a surface exposed when the snow-melting block 50 is laid on the road surface, and a plurality of watering nozzles 52, 52,. In addition, the snow removal block 50 is provided with a water passage tube 54 extending in the longitudinal direction, and water spray nozzles 52, 52,... Are connected to the tips of the tubes branched from the water passage tube 54. Therefore, when the snow-melting block 50 is laid on the road surface and ground water or the like is supplied to the water pipe 54 at a predetermined water pressure, the snow that has been sprinkled from each of the water spray nozzles 52, 52,. ing.

  Such a snow-melting block 50 is formed of reinforced concrete, and a reinforcing bar for reinforcing the snow-blocking block 50 or a protective reinforcing bar for protecting the water pipe 54 is provided therein. As shown in FIG. 3A, the rebar cage 55 is composed of a car body 56 having a substantially U-shaped groove shape and a net body 57 having a flat plate shape. The car body 56 is formed by welding from a plurality of U-shaped reinforcing bars 59, 59,...

Japanese Patent Laid-Open No. 10-311013

  Since the snow-removing block 50 can also be manufactured using the conventional reinforcing steel basket 55, there is no particular problem as a snow-removing block. However, there are also problems to be solved. In the conventional reinforcing steel car 55, when the car body 56 and the net body 57 are integrated by welding, the net body 57 falls unless the net body 57 is supported. Or, as shown in FIG. Therefore, when integrating by welding, it is carried out in a state in which one end and the other end of the net body 57 are supported by an assistant operator and the net body 57 is fixed. If it does so, two assistant workers will be needed in addition to a welding worker, and manufacturing cost will increase. Alternatively, if a special jig for supporting the net 57 is prepared, the net 57 may be supported at the time of welding without an assistant worker. However, there is a problem that a jig is particularly necessary, and it is necessary to install the jig before welding and to remove the jig after welding, which is complicated.

  The present invention aims to provide a rebar cage for manufacturing a snow-melting block that solves the conventional problems as described above. Specifically, the manufacturing cost is low and a special jig is required. An object of the present invention is to provide a reinforcing bar cage for manufacturing a snow-breaking block, which is easy to carry out during manufacturing.

  In order to achieve the above object, the present invention has an elongated rectangular parallelepiped shape, and a plurality of watering nozzles are embedded in an upper surface exposed when laid on a road surface, and water supplied from a water pipe provided therein. Is a reinforcing bar cage for manufacturing a snow-melting block that is sprinkled from the watering nozzle and melts snow on the road surface. The car body having a groove shape and a flat net body, the water pipe having the watering nozzle is inserted into the car body from the opening, and the opening is closed by the net. The car body and the net body are fixed together by welding, and when concrete is placed, a snow squeezing block is manufactured, and the car body has a substantially U-shaped first, 2 rebars and straight bar rebars A plurality of first and second rebars are provided at predetermined intervals along two or more bar rebars arranged in parallel, and are fixed to the bar rebars by welding, The first rebar is formed in a substantially U shape by bending two places from one rebar, and the second rebar is formed in a substantially U shape by bending two places from one rebar. In addition, it is formed in a claw shape by being bent inward in the vicinity of both ends, and when the mesh body is inserted into the opening of the car body, the mesh body is formed by the claw-shaped portion of the second reinforcing bar. It is configured as a reinforcing steel basket for manufacturing a snow-melting block, which is characterized by being supported.

  As described above, according to the present invention, it has an elongated rectangular parallelepiped shape, and a plurality of watering nozzles are embedded in the upper surface exposed when laid on a road surface, and water supplied from a water pipe provided inside is watered. A snow-removing block sprayed with water from a nozzle and melts snow on the road surface is configured as a rebar cage for manufacturing the block. In other words, the present invention can be said to be a steel basket for manufacturing a general snow-breaking block. In other words, it corresponds to virtually all snow removal blocks. And, the reinforcing steel car is composed of a car body having a substantially U-shaped groove shape with one surface opened, and a flat net body, and a water pipe equipped with a watering nozzle is inserted into the car body from the opening, When the opening is closed by the mesh body, the car body and the mesh body are fixed together by welding, and concrete is placed, a snow-breaking block is manufactured. That is, reinforcement and protection of water pipes, which are the purposes of the reinforcing steel basket, are the same as in the prior art, and the method for manufacturing the snow-melting block is the same as in the prior art. In other words, it can be understood that almost all snow-melting blocks can be used in this respect as well. And according to this invention, a cage | basket body is comprised from the 1st, 2nd reinforcing bar which exhibits a substantially U-shape, and a linear bar-shaped reinforcing bar, along two or more bar-shaped reinforcing bars arranged in parallel, A plurality of first and second rebars are provided at predetermined intervals, and are fixed to the bar-shaped rebar by welding, and the first rebar is bent at two locations from one rebar into a substantially U-shape. The second reinforcing bar is formed in a substantially U-shape by bending two portions from one reinforcing bar, and is further bent inward in the vicinity of both ends to form a claw shape. When the net is inserted into the opening, the net is supported by the claw-like portion of the second reinforcing bar. That is, in the car body of the present invention, the net body put in the opening is supported by the claw-like portion of the second reinforcing bar. Then, even if there is no assistant worker or no special jig, only one welding worker can fix the car body and the net body by welding to obtain a reinforcing steel car. Therefore, the manufacturing cost of the snow-melting block is small and the work efficiency is high.

Hereinafter, the reinforcing steel basket 2 for manufacturing the snow-melting block 1 according to the embodiment of the present invention will be described.
The rebar cage 2 according to the present embodiment is also composed of the car body 3 and the net body 4 as shown in FIG. It is configured. Although the car body 3 and the net body 4 shown in the figure are formed relatively short in the longitudinal direction, the length in the longitudinal direction is appropriately designed according to the length of the snow-melting block to be manufactured. Also in the present embodiment, the net 4 of the reinforcing bar 2 is formed by welding from the linear reinforcing bars 15, 16,... Like the conventional car body, and has a flat rectangular shape.

  On the other hand, the car body 3 is composed of reinforcing bars having the same shape as a conventional car body and reinforcing bars having a predetermined shape unique to the present invention. The reinforcing bars having the same shape as the conventional one are the bar-shaped reinforcing bars 8 and the first reinforcing bars 7. The rod-shaped reinforcing bar 8 is a linear reinforcing bar. On the other hand, the first reinforcing bar 7 is bent at a substantially right angle at two locations from one reinforcing bar, and has a substantially U-shape. Therefore, the first reinforcing bar 7 can also be called a U-shaped reinforcing bar. However, in the present embodiment, the two bent portions of the first reinforcing bar 7 are formed at an obtuse angle slightly larger than a right angle, whereby the first reinforcing bar 7 has a shape in which the U-shape is slightly opened. It has become. Therefore, when the rebar cage 2 is formed from the car body 3 and the net body 4, when the rebar car 2 is viewed from the side, it has a trapezoidal shape.

  The reinforcing bar unique to the present invention constituting the car body 3 is a second reinforcing bar 9. The second reinforcing bar 9 is also bent from one reinforcing bar having substantially the same length as that of the reinforcing bar forming the first reinforcing bar 7, and as shown in FIG. It has a shape similar to the rebar 7. In other words, it can be said that the two portions bent in the middle have a right angle or an obtuse angle slightly larger than the right angle, and have a substantially U-shape as a whole. However, it is further bent inward in the vicinity of both tip portions. That is, the second rebar 9 is bent at four locations. In this way, the claw portions 11 and 11 projecting inward are formed by being bent in the vicinity of both tip portions. In the figure, the claw portions 11 and 11 are bent relatively long and drawn large, but since a water pipe or the like is put into the car body 3 as will be described later, the claw portions 11 and 11 are actually used. Is made small so as not to interfere with the work.

  The car body 3 according to the present embodiment is formed from a plurality of first reinforcing bars 7, 7,..., A plurality of second reinforcing bars 9, 9,. Has been. Specifically, with respect to the bar-shaped reinforcing bars 8 and 8 arranged in parallel, the first and second reinforcing bars 7, 9,... The joint points of the reinforcing bars 7, 8, 9 are fixed by welding. In addition, although the rod-shaped reinforcing bars 8 and 8 are comprised from 2 in this Embodiment, you may be comprised from 3 or 4.

  In order to carry out the present invention, at least two or more second reinforcing bars 9, 9,... Constituting the car body 3 are necessary. When the mesh body 4 is inserted into the opening of the car body 3, the mesh body 4 is locked by the claws 11, 11,... Of the second reinforcing bars 9, 9,. This is because it is necessary to support 4 at least at two or more locations. Similarly, at least two first reinforcing bars 7, 7,... Constituting the car body 3 are also required. This is because when the mesh body 4 is supported by the claws 11, 11,... Of the second reinforcing bars 9, 9,..., The mesh body 4 needs to be pressed from the side so as not to be displaced laterally.

  A method for manufacturing the snow-melting block 1 according to the present embodiment will be described. The car body 3 according to the present embodiment is installed with its opening facing up. Next, the water pipe 21 provided with the watering nozzle 20 is put into the car body 3 so that the watering nozzle 20 faces downward. Next, the mesh body 4 is put into the opening of the car body 3. This state is shown in FIG. The mesh body 4 is locked by the claw portions 11, 11,... Of the second reinforcing bars 9, 9,. That is, it is supported. The car body 3 and the net body 4 are fixed by welding. That is, the reinforcing bar 2 having the water pipe 21 provided inside is obtained. This is put into a predetermined formwork and concrete is laid. When it is solidified and removed from the formwork, the snow-blocking block 1 is obtained.
