Description

The present invention relates to a piping floor band that supports and fixes pipes at a fixed height to a fixed surface such as a floor or wall.

When installing a piping floor band, first the base plate is attached to a fixed surface such as a floor. Two support bolts are already installed on the base plate at the time of shipment from the factory, and lower nuts are screwed into each of the support bolts in appropriate positions.
Next, the lower bridge for supporting the pipe is inserted through the support bolt, and then the pipe is placed on the band of the lower bridge to support it. The pipe height can be adjusted by adjusting the screw-in height of the lower nut.
The upper bridge is inserted and attached to the support bolt, the upper nut is screwed onto the top end of the support bolt, and the upper nut is rotated to the tightening position and tightened, so that the pipe is supported from above and below by the band portions of the pair of upper and lower bridges.

In the above construction work, the upper nut must be screwed onto the support bolt after the pipe has been placed on the band part of the lower bridge and the upper bridge has been inserted and attached to the support bolt. Furthermore, the upper nut must be screwed into the top end of the support bolt and then rotated to the tightening position. Considering the number of floor bands to be installed at the construction site, screwing in this upper nut takes a considerable amount of time, resulting in low work efficiency.

Patent documents 1 to 5 describe a technology in which the bolt holes for inserting the support bolts, which are provided in one mounting part of the upper bridge, are cut into grooves with an opening in the piping direction, so that piping work can be performed even when the upper nuts are already screwed onto both of the two support bolts.
In other words, unlike previous methods in which the pipe was supported by the lower bridge, the upper bridge was set, and then the upper nut was screwed on and tightened, with these techniques the upper nut can be screwed onto the support bolt in advance, which has the advantage that work can be carried out on site without dropping the upper nut.

However, the technologies in Patent Documents 1 to 5 above have the problem that the bolt holes in the mounting part are cut grooves, and if the nut loosens even slightly due to the water hammer phenomenon or the like, the mounting part with the cut grooves will fall off the support bolt, making it impossible to hold the pipe. If the nut is tightened too much to prevent it from loosening, the open part of the bolt hole will deform and expand, resulting in a problem of reduced fixing area and strength of the mounting part.

The objective of the present invention is to provide a piping floor band that is highly efficient to use without compromising the fixing area and strength of the attachment part to the support bolt.

The present invention, which solves the above problems, has the following configuration.

1. A floor band for piping, comprising a base plate attached to a fixed surface, two support bolts erected on the base plate, a bridge having a band portion for embracing and supporting a pipe and a mounting portion having holes formed at both ends of the band portion through which the support bolts are inserted, a lower nut screwed onto the support bolts to support the mounting portion from below at an arbitrary height position, and an upper nut inserted into the support bolts to press and support the mounting portion from above,
The lower nut has a nut body and a male threaded column part that is erected on the upper surface of the nut body and has a male thread formed on its outer periphery. Further, a through hole is formed that penetrates from the upper surface of the male threaded column part to the lower surface of the nut body, and a female thread is formed on the inner circumferential surface of the through hole, into which the support bolt is inserted and screwed.
The upper nut has a female thread that is screwed into the male thread of the male thread column of the lower nut,
This floor band for piping is characterized in that the upper nut inserted from the upper end of the support bolt passes through the male threaded portion of the support bolt and screws into the male threads of the male threaded column portion of the lower nut, and is tightened while screwed into this male threaded column portion to support the mounting portion from above.

2. The piping floor band described in item 1 above, characterized in that the lower nut has an integral structure of the nut body and male thread column.

3. The floor band for piping described in 1 or 2 above, characterized in that the bridge consists of a pair of upper and lower bridges, and the pipe is held from above and below by the band portion of the lower bridge and the band portion of the upper bridge.

4. The floor band for piping described in 1 or 2 above is characterized in that the band portion of the bridge supports the lower part of the pipe, and a band-shaped body, both ends of which are fixed to the bridge, is supported above the pipe, thereby embracing the pipe from above and below.

According to the invention shown in claim 1, it is possible to provide a piping floor band that is highly efficient to work with, without compromising the fixing area and strength of the mounting part for the support bolt.

In particular, in the conventional configuration consisting of an upper nut and a lower nut, the screwing and attachment of the upper nut to the support bolt requires the nut screwed onto the upper end of the support bolt to be rotated endlessly and moved to the tightening position. However, according to the present invention, the upper nut passes through the male threaded portion of the support bolt and screws into the male threads of the male threaded column portion of the lower nut, and the bridge mounting portion can be supported by pressing from above simply by tightening it while screwed into this male threaded column portion. Therefore, even if the support bolt is long, there is no need to rotate and move the upper nut endlessly, making it easier to work with.

In particular, when adjusting the piping height of a pipe, in the conventional configuration consisting of an upper nut and a lower nut, when lowering the position, the lower nut is first rotated to a desired position and then the upper nut is rotated the same amount as the lower nut to lower it, and when raising the position, the upper nut is first rotated to a desired position and then the lower nut is rotated the same amount as the upper nut to raise it, and in either case, the height position of either the upper nut or the lower nut or both are adjusted and tightened to adjust the position. However, according to the present invention, when lowering or raising the position, simply rotating the lower nut to the desired position also moves the upper nut that is screwed into the male threaded column of the lower nut, eliminating the need to rotate and move the upper and lower nuts separately. Therefore, the workability when adjusting the height is also high.

According to the invention shown in claim 2, the integrated structure allows the nut body and the male threaded column to be stably maintained in a tightened state without separation even when tightened strongly.

The invention shown in claim 3 can be applied to a floor band using a piping support band consisting of a pair of upper and lower bridges.

According to the invention shown in claim 4, the pipe is supported from below by a lower bridge, and the pipe is supported from above by a floor band that embraces and supports the pipe with cable ties or metal or plastic hose bands.

Next, the details of the present invention will be described based on the embodiment shown in Figures 1 to 12.

The piping floor band (hereinafter, simply referred to as the floor band) 1 according to the present invention is
A structure having a base plate 2 to be attached to a fixed surface (not shown) such as a floor surface or a slab surface, two support bolts 3 erected on the base plate 2, a pair of upper and lower bridges 4 each having a band portion 41 for embracing and supporting a pipe P and a mounting portion 42 having a through hole 42A formed at both ends of the band portion 41 for inserting the support bolt 3, a lower nut 5 screwed onto the support bolt 3 to support the mounting portion 42 from below at an arbitrary height position, and an upper nut 6 inserted into the support bolt 3 to press and support the mounting portion from above,
As shown in Figs. 2 and 4, the lower nut 5 has a nut body 51, and a male threaded column 52 that is erected on the upper surface of the nut body 51 and has a male thread 52A formed on its outer periphery. Furthermore, a through hole 53 is formed that penetrates from the upper surface of the male threaded column 52 to the lower surface of the nut body 51, and a female thread 53A into which the support bolt 3 is inserted and screwed is formed on the inner circumferential surface of the through hole 53.
As shown in FIGS. 3 and 4, the upper nut 6 has a configuration in which a female thread 61 is screwed into the male thread 52A of the male thread column portion 52 of the lower nut 5.
The upper nut 6 inserted from the upper end of the support bolt 3 passes through the male thread portion of the support bolt 3 and screws into the male threads 52A of the male thread column portion 52 of the lower nut 5 as shown in Figures 9 and 10. In the screwed state into this male thread column portion 52, the upper nut 6 is tightened as shown in Figures 1, 11 and 12, thereby pressing and supporting the mounting portion 42 from above.

In the figure, the reference numeral 21 denotes a fixing nut attached and fixed to the top surface of the substrate 2, and the support bolt 3 can be fixed in an upright position to the substrate 2 by screwing it into the fixing nut 21.

In this embodiment, the bridge 4 is made up of a pair of upper and lower bridges 4, and the band portion 41 of the lower bridge 4 and the band portion 41 of the upper bridge 4 embrace the pipe P from above and below. In addition, the lower nut 5 supports the mounting portion 42 of the lower bridge 4 from below, and the upper nut 6 presses and supports the mounting portion 42 of the upper bridge from above.

In addition, in this embodiment, the lower nut 5 has an integrated structure in which the nut body 51 and the male threaded column 52 are integrally formed by machining or the like from a single member, but it may also be a structure in which separate pieces are combined.

Next, an example of the installation procedure for the floor band 1 of the present invention having the above configuration will be described.

First, as shown in FIG. 5, the base plate 2 is fixed to a fixing surface (not shown) such as a floor surface or a slab surface. Two support bolts 3 are already installed on the base plate 2, and a lower nut 5 is screwed onto each of the support bolts 3. Of the pair of upper and lower bridges 4, the lower bridge 4 is attached to the installed support bolts 3. The through hole 42A provided in each mounting portion 42 of the pair of upper and lower bridges 4 has a diameter large enough to insert the male threaded column portion 52 of the lower nut 5.

Next, as shown in Figure 6, the pipe P is placed on the band portion 41 of the lower bridge 4.

Next, as shown in FIG. 7, the upper bridge 4 is attached to the support bolt 3. With this attachment, the pipe P is supported from above and below by the pair of upper and lower bridges 4.

Next, as shown in Figures 8 to 9 and 10, the upper nut 6 is inserted from the upper end of the support bolt 3. At this time, the upper nut 6 passes through the male threaded portion of the support bolt 3 without being screwed into it, and is screwed into the male threads 52A of the male threaded column portion 52 of the lower nut 5.

Next, by tightening the upper nut 6 while it is screwed into the male threaded column portion 52, as shown in Figures 1, 11 and 12, the nut body portion 51 of the lower nut 5 supports the mounting portion 42 of the lower bridge 4 from below, and the upper nut 6 presses and supports the mounting portion 42 of the upper bridge 4 from above, so that the pipe P is embraced and supported by the upper and lower band portions 41 in a stable state.

As described above, the upper nut 6 is screwed onto the support bolt 3 by passing through the male threads of the support bolt 3 and screwing into the male threads 52A of the male threaded column portion 52 of the lower nut 5, and simply tightening the nut while screwed into the male threaded column portion 52 to support the mounting portion 42 of the upper bridge 4 from above. Therefore, even if the support bolt 3 is long, there is no need to endlessly rotate and move the nut screwed onto the upper side as with conventional general nut configurations, which makes it easy to work with.

The support height of the pipe P is adjusted before the upper nut 6 is tightened, i.e., in the state shown in Figures 9 and 10. According to the present invention, whether the support height is to be lowered or raised, the upper nut 5 that is screwed into the male threaded column portion 52 of the lower nut 5 is moved together with the lower nut 5 simply by rotating the lower nut 5 to the desired position, eliminating the need to rotate and move the upper and lower nuts separately. This makes height adjustment easy to do.

The above describes an embodiment of the piping floor band according to the present invention based on Figures 1 to 12, but the present invention is not limited to the above embodiment and other aspects may be adopted within the scope of the present invention.

For example, the bridge 4 having the band portion 41 and the mounting portion 42 is not limited to the upper and lower pair configuration of the above embodiment, but may be configured so that only the lower side of the pipe P is supported by the bridge 4, and the upper side is supported and embraced by a cable tie or a metal or resin hose band.

In the embodiment shown in Figures 13 and 14, a concave portion is formed in the center of the downwardly arcing band portion 41 of the lower bridge 4, and the pipe P is supported at two points from below only at two corners which are the contact points between both ends of this concave portion and the left and right arc portions, and a strip-shaped body 7 made of a cable tie is passed through a fixing slit 41A formed in the band portion 41 to span above the pipe P supported on the lower bridge 4 and support it.
According to this configuration, the pipe P is supported from below at two points at the two lower corners, so even if the arc shape of the band part 41 of the bridge 4 does not match the outer diameter shape of the pipe P, the pipe can be supported while being fixed to the center part of the band part 41. Therefore, the bridge 4 having the band part 41 according to the diameter of the pipe P to be embraced and supported can support pipes P of various diameters.
