[Effects of the Invention] As described above, the header according to the present invention is provided integrally with the fixing part to the building frame in a part of the header, so it is not necessary to use a header bracket. Fixing work is not required, and the header can be fixed directly to the building frame with simple work, greatly improving work efficiency. In addition, since the branch resin pipe support portion is provided on a part of the header concentrically with the axis of the branch portion, the branch portion and the branch resin tube can be fixed to the header in a state in which the axis of the branch resin tube coincides with the header. (Plastic tube protector) is no longer required. Therefore, after the energization is completed, there is no need to wait for the fusion portion to cool down and then remove the clamp tool, thereby greatly improving the work efficiency. Further, the interval between the branches provided for attaching and detaching the clamp tool (resin pipe protector) is not required, so that the pitch between the branches can be reduced, and the overall length of the header is about 50% shorter than that of the conventional product. Because of this, there is an effect of space saving and cost reduction.
