It is formed into a shape. In other words, it can be said that the inner path 11f of the pipe section 11 is formed in a semicircular shape in cross section from the position where the opposite long side second pipe section 12 intersects the front end side to the base end side. .
That is, the first pipe line part 11 and the second pipe line part 12 are formed in a cylindrical shape on the distal end side with a step part on the way, and in a semi-cylindrical shape on the proximal end side. In the present invention, the semicircle means a D-shape having a cross-sectional area of 40% to 80% with respect to the cross-sectional area of the base circle.

  In FIG. 1, the reinforcing portion 13 is formed in a rectangular shape in plan view, and includes a front surface 13a formed on the distal end side in the direction of the axis L1 and a rear surface 13b formed on the proximal end side in the direction of the axis L1. And an upper surface 13d.

The side wall portion 30 is provided so as to be inserted into the space portion 14 and flush with the other side surface 13e.

  In FIG. 2, all the reinforcing portions 13 are combined in a flat box shape having a rectangular shape in plan view. In other words, a plurality of reinforcing portions 13 are combined with each other to form one flat box-shaped (cuboid) block portion having six faces, and a pair of first conduit portions 11 and 11 are projected from the front surface, It can be said that it has a shape in which a plurality of second pipe sections 12 are projected from the left and right side surfaces.

The usage method (action) of the above-described header unit for floor heating piping of the present invention will be described.
1 and 2, a pair of branch pipe members 10 and 10 are arranged at point-symmetrical positions, and the front surface 13a, the rear surface 13b, and the lower surface 13c of the intermediate reinforcing portion 13 are used as the mating reinforcing portion 13. By making contact with each other and fitting the reinforcing portion 13 into the space portion 14 on the other side, the movement in the front-rear direction is restricted, and the mutual side wall part 30 restricts the movement in the left-right direction and maintains a predetermined posture. Thus, a flat box shape that can be easily arranged during construction is used.

  Compared with the case where two conventional headers are arranged side by side, the dimension in the width direction of the space (area) required for the arrangement is ½ or less. In addition, the thickness in use is the same as in the case of one branch pipe member 10, and the thickness of the space (height) required for installation compared to the case where two conventional headers are arranged side by side. The direction dimension is less than half.

One branch pipe member 10 is used for the inlet side, and the remaining branch pipe member 10 is used for the outlet side. The first pipe line part 11 connected to the heat medium supply source side and the first pipe line part 11 connected to the recovery destination of the heat medium come close to each other and project in the same direction. In addition, the second pipe part 12 connected to the inlet side of the heat radiating pipe is obtained on both the left and right sides, and the second pipe part 12 connected to the outlet side of the heat radiating pipe is obtained on the left and right sides. Further, a second conduit section 12 for the inlet side, a second conduit section 12 for the exit side, but the side surfaces, are arranged alternately.

  As shown in FIG. 11, the first pipe section 11 and the second pipe section 12 arranged in this way are radiating pipes (flow paths) and branch pipe members 10 provided on the floor Y indicated by a two-dot chain line. , It is possible to make the pipes in the left and right equally beautiful without making a three-dimensional intersection of the pipes in the vicinity of 10. Moreover, it is possible to make it substantially equal forward and backward. Specifically, the second pipe sections 12 and 12 adjacent to the front and rear (in the direction of the axis L1) in the use state are set as one set (for the inlet side and the outlet side), and the floor is set according to the number of sets (four sets). A pipe that partitions the heating range of Y (four sections) can be easily obtained. In FIG. 11, for ease of explanation, the floor heating piping header unit of the present invention is shown larger than the actual size compared to the floor Y and piping.

  The design of the present invention can be changed. For example, it is preferable that the tips of the first and second pipe sections 11 and 12 have a shape corresponding to a heat radiating pipe or a joint to be connected. For example, a shape with an arrowhead-shaped warp or notch that prevents a resin pipe or hose from coming off, a shape with an outer flange that regulates the insertion length, a shape with a threaded portion, etc. It is. Further, each branch pipe member 10 is free to provide three or more second pipe sections 12 on the left and right sides.

  As described above, the present invention includes the first main line section 11 for main lines, the second pipe section 12 for branching projecting from the first pipe section 11 alternately in the left and right directions, and the second pipe line. And a pair of branch pipe members 10, 10 having the same shape and having a reinforcing part 13 that supports the part 12, and is provided on the opposite side of the second pipe part 12 across the first pipe part 11. Since the space part 14 and the mating part 13 on the mating side are fitted to each other so that they can be used together, the pipes for the inlet side and the outlet side are brought close to each other and placed in a small space. It is possible to use the floor area for heating effectively. Easy installation, inspection and maintenance of piping. The heat medium can be distributed to the left and right sides and the heat medium can be recovered from the left and right sides without piping the radiator tubes in a three-dimensional intersection.

  In addition, since the pair of branch pipe members 10 and 10 are disposed at point-symmetrical positions when viewed from the horizontal direction parallel to the first pipe line section 11 in use, only one type of the same shape is required. It can be easily and inexpensively mass-produced by injection molding or the like. It can be easily combined by rotating 180 degrees. Heating piping work becomes easy as the right and left piping.

  Further, the second pipe part 12 on one side of the left and right sides is formed short and the second pipe part 12 on the other side of the left and right sides is formed long so that the long second pipe part 12 in the use state. However, since it corresponds to the first pipe section 11 on the other side in a three-dimensional crossing, it can be applied to a beautifully symmetric pipe. The heat medium can be supplied in the left-right direction and the heat medium can be recovered from the left-right direction.

  In addition, since the long second pipe section 12 is formed in a semicircular cross section at the three-dimensional intersection, and the first pipe section 11 on the other side is formed in a semicircular cross section at the three-dimensional intersection, As shown in FIG. 10, the overall thickness can be made thinner than twice the outer diameter D of the second conduit portion 12.

  Further, in the state of use, the intermediate reinforcing portion 13 excluding the reinforcing portions 13 and 13 on the distal end side and the proximal end side in the direction of the axis L1 of the first conduit portion 11 is the front surface 13a and the rear surface 13b of the intermediate reinforcing portion 13. And the lower surface 13c are brought into contact with the mating reinforcing portion 13 so that they can be easily assembled and misalignment can be prevented.

  In addition, since it is combined in a flat box shape with a rectangular shape in plan view by all the reinforcing parts 13 in the state of use, sufficient strength and rigidity can be obtained, and it is compact and small for floor heating piping. It is suitable for installation in a space.
