[0007]
DETAILED DESCRIPTION OF THE INVENTION
The illustrated support device has tube holders 1 arranged vertically and vertically below and above each tube layer at the mounting position, and these tube holders 1 are arranged on the upper side surface and the lower side surface. It has a number of notches 2 for receiving the tubes, these notches being spaced apart from each other and diametrically facing each other. In the illustrated embodiment, the tube holder 1 has three notches 2 on the upper and lower sides, respectively, so that the tube holder 1 supports three tubes within the tube layer. Suitable. However, it is of course possible for the number of notches 2 to be two, four and more. The number of tube layers is not limited to three, and may be two, four and more.
[0008]
The notches 2 all have a trapezoidal cross-sectional shape, in which case the laterally expanding side surfaces 3 respectively have a base surface 4 located between these side surfaces 3 of 120 ° to 150 °, advantageously Is at an angle of 135 °. The expanding side surface 3 is shifted to the outer surface 5 of the tube holder 1 extending parallel to the base surface 4 on the outer surface side, and these outer surfaces 5 are tubes located at the uppermost part or the lowermost part in the unit. In the holding body 1, it is used as an installation surface.
[0009]
On the end side, the tube holder 1 has a flat end face 6 that is perpendicular to the mounting position, and these end faces 6 connect the outer edge parts 7 and 8 of the inner adjacent outer face 5, respectively. ing. In this case, the end face of the tube holder 1 is provided with a groove 9 that passes vertically from the top to the bottom at the mounting position, and this groove 9 is provided when the tube holder 1 is inserted into the unit. It is used to introduce the fastening means 10.
[0010]
At all ends of the tube holder 1, a transverse hole 11 extending and penetrating at the height of the horizontal central plane 12 of the tube holder 1 is a transverse insertion member that freely traverses the groove 9 on the end side. 13 to receive. These lateral insertion portions 13 that can be fixed via the split pins are inserted into the lateral holes 11 of the tube holder 1 located at the top or bottom of the unit. These lateral insertion members 13 are used to support the clamping means 10. The fastening means 10 can be configured as a flat belt guided around the lateral insertion member 13, which can be fastened by a ratchet turnbuckle 14.
[0011]
In order to attach the ratchet type turnbuckle 14 as described above to the lateral insertion member 13 of the uppermost tube holder 1 in the unit, for example, at the height of the lateral hole 11 and the groove inside the groove 9. An inner groove 15 perpendicular to the end surface 6 of the tube holder 1 is provided on the side wall. Since the width of the inner groove 15 is larger than the diameter of the lateral hole 11 or the lateral insertion member 13 that can be received in the lateral hole 11, the attachment portion of the ratchet type turnbuckle 14 is provided in the inner groove 15. Can extend. If another clamping means is used, the inner groove 15 may be removed correspondingly.
[0012]
If the tube holder 1 is preferably made from a polymer material, a reinforcing insert 17 is provided in the central part 16 of the tube holder 1 located between the notches 2 on both sides. The reinforcing insert 17 is preferably made of a metallic material, such as steel, and is cast or injected into the tube holder 1. The reinforcing insert 17 is preferably formed as a support having a double T-shape and profile, the central leg 18 of such a support being parallel to the base surface 4 of the notch 2. Are arranged in the center between the base surfaces 4 (see FIG. 6). The reinforcing insert 1717 extends over substantially the entire length of the tube holder 1, but the end face side is covered with the material of the tube holder 1. As also illustrated in FIG. 6, the reinforcing insert 17 occupies most of the width and height of the central portion 16 of the tube holder 1. In the region of the groove 9, the central leg 18 of the reinforcing insert 17 is notched to some extent while the end surface of the central leg is covered with the material of the tube holder 1.
[0013]
As polymer material, plastics such as polyethylene are preferably used. Such a plastic material has a sufficient strength and a certain degree of flexibility, for example a Shore hardness D of 43 to 48, so that the tube received in the notch 2 is a tube. After the holding body 1 is tightened, the side surface 3 or the side surface 3 and the base surface 4 are engaged with each other in a strip-like contact area instead of a linear shape.
[0014]
As can be seen from FIG. 3, the tube is positively received and supported in the notch 2. The diameter of the tube can vary over a wide area, but of course only tubes having the same diameter in one tube layer may be supported. The applicable diameter area in each case is set according to the geometric shape of the trapezoidal notch 2, ie the inclination of the side surface 3 and the mutual spacing of the side surface 3 at the height of the base surface 4. The shape of the notch 2 ensures that any tube having a diameter value within a predetermined diameter region contacts at least the side surface 3 or the side surface 3 and the base surface 4 of each notch 2.
[0015]
Instead of the flat belt 10 and the ratchet type turnbuckle 14 for the case where the pipe to be attached is heavy, a screw type turnbuckle 20 may be provided as a tightening means. The outer cross section is formed of a hexagonal hollow fastening rod 21 and two fastening members 22. The tightening rod 21 has an inner thread 21 ′ opposite to each end, and a tightening pin 23 provided with an outer thread 23 ′ of the tightening member 22 is screwed to the inner thread 21 ′. It is possible to enter. Each of the two clamping pins 23 has a clamping hook 24, and each of the clamping hooks 24 can be mounted on the lateral insertion member 11. An eye (eye hook) may be used in place of the at least one clamping hook 24.
[0016]
7 and 8 is tightened by using a screw spanner applied to the tightening rod 21 or, for example, an insertion opening is provided in the tightening rod 21 in the region between the two tightening members 22. If it is, it is performed by rotating the fastening rod 21 using the fastening lever member. In such an embodiment, the clamping bar 21 may have any outer cross section, for example a circular cross section.
[0017]
Any suitable known means can be used to fix the clamping position of the components of the screw type turnbuckle 20. In a particularly simple embodiment, at least one clamping bolt 23 is provided with a locking nut 26, which can be screwed in opposing engagement with the end face of the clamping bar 21 adjacent thereto. .
