2. Description of the Related Art Conventionally, as a support of this type, for example, Japanese Patent Application Laid-Open No. 6-300166 or Japanese Patent Application
No. 04 was disclosed. These conventional supports are mainly used for supporting a drainage pipe joint on a concrete slab, and include a mounting portion for the pipe joint, an arm portion extending in a T-shape to both sides of the pipe joint, and both arms. Providing butting bolts protruding downward from each part and abutting against the upper surface of the concrete slab, and adjusting the amount of projection of both butting bolts to position the pipe substantially at right angles to the concrete slab After the slab hole was backfilled with mortar, it also functioned as an auxiliary tool for more firmly supporting the pipe joint to the concrete slab.

[0003]

However, the conventional support has the following problems. That is, the abutment bolts are attached one by one to both arm portions. However, since the respective attachment positions are fixed (one place), the abutment bolts are located, for example, above the slab holes. Or other piping may be in the way,
There was a problem to be improved in terms of its usability.

An object of the present invention is to provide a highly versatile pipe support capable of adjusting the mounting position of a butting bolt.

[0005]

According to a first aspect of the present invention, there is provided a support for attaching a pipe to a pipe, a plurality of arms extending laterally of the pipe, and a pipe protruding downward from each arm. A striking member struck against the upper surface of the fixing portion is provided, and a mounting position of the striking member with respect to the arm portion can be changed.

According to this support, by changing the mounting position of the butting member with respect to the arm portion, it is possible to change the butting position of this butting member with respect to the pipe fixing portion. The abutment member can be firmly abutted against the tube fixing portion without being disturbed by the mortar and avoiding the backfill portion of the mortar.

According to a second aspect of the present invention, there is provided the support according to the first aspect, wherein a plurality of mounting holes are provided in an arm portion while a plurality of mounting holes are provided in the arm portion while using a butting bolt as a butting member. Is selected so that the mounting position of the abutment bolt can be changed.

According to this support, the mounting position of the butting bolt to the arm does not shift due to vibration or the like. In order to make it possible to change the mounting position of the butting bolt on the arm, if a long hole is formed in the arm portion and the butting bolt is inserted through this long hole, the Although the position can be continuously changed, the position may be shifted due to vibration or the like, and the position of the pipe may be shifted. However, according to the configuration of claim 2, since the mounting position of the butting bolt is changed by selecting the mounting hole at an appropriate position from the plurality of mounting holes, the mounting hole at a certain position is temporarily set. After the abutment bolt is inserted, the mounting position does not shift due to vibration or the like, whereby the pipe can be fixed at the original position for a long period of time.

According to a third aspect of the present invention, there is provided the support according to the second aspect, wherein the plurality of mounting holes communicate with each other within a range in which the abutment bolt does not pass.

According to this support, the mounting position of the butting bolt can be changed at a pitch equal to or less than the diameter of the mounting hole, so that the mounting position can be changed more finely and the arm portion can be changed. Compactness can be achieved. In addition, since the plurality of mounting holes communicate with each other, when the arm portion is made of a casting, the casting is facilitated, whereby the casting cost can be reduced.

In the constructions according to the second and third aspects, the mounting hole includes not only a case where the abutment bolt is simply inserted but also a case where a tapped screw hole is provided. In the case of a simple insertion hole, the amount of protrusion of the butting bolt can be changed by adjusting the tightening position of the fixed nut tightened to the butting bolt. The amount of protrusion from the arm portion can be changed by adjusting the amount of screwing by rotating.

According to a fourth aspect of the present invention, there is provided the support device according to the first aspect, wherein the support member has a half-circle structure including two support pieces each having an arm portion formed in a semicircular portion. It is characterized in that a configuration is such that the tube is sandwiched from both sides in the radial direction and connected, and the support is attached to the tube.

According to this support, the semicircular portions of the two support pieces constitute an attachment portion, and the two semicircular portions are joined by sandwiching the tube from both sides in the radial direction. Therefore, the work of attaching the support to the pipe is simplified, and the support can be easily removed from the pipe even after construction.

Further, since the two support pieces have the same shape, not only are they easy to handle, but they can also be used on either the left or right side. For example, even if one is damaged, the other can be used as it is. As a result, maintenance costs can be reduced as compared with the integrated type.

According to a fifth aspect of the present invention, there is provided a support for attaching to a pipe, a plurality of arms protruding to the side of the pipe, and a suspension protruding upward from each arm and fixed to a lower surface of the pipe fixing section. A hanging member is provided, and the hanging member is configured to be able to arbitrarily select a mounting position with respect to the arm portion and to be fixed to the tube fixing portion.

According to this support, the pipe joint can be supported in a suspended manner on a pipe fixing portion such as a concrete slab. When the leg joint is supported by using the support having such a configuration, the same operation and effect as described above can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 1 shows a drainage pipe joint 1 as an example of a pipe fixed to a concrete slab S as an example of a pipe fixing section. A drainage stack P on the upstream side is provided at an upper receptacle 1a of the drainage stack fitting 1.
1, and a drainage stack P2 on the downstream side is connected to the lower receptacle 1b. In addition, a plurality of horizontal branch pipe receiving ports 1c to 1c are provided on the side portions thereof.
Is connected.

The drainage pipe fitting 1 is inserted into the slab hole Sa formed in the concrete slab S from the upper floor side, and the axis of the upper receiving port 1a (or the lower receiving port 1b) (hereinafter referred to as the axis of the pipe fitting 1). Is fixed to the state shown in the figure by pouring mortar M into the slab hole Sa and back-filling the slab hole Sa while the slab hole is positioned vertically. No change is required in this regard.

As described above, the drain stack fitting 1 is inserted into the slab hole S
When setting to a, the support 10 of the present embodiment described below is used. This support 10 is shown alone in FIG. However, the butting bolts 11, 11 are omitted.

The support 10 has two support pieces 12, 1
It has a split structure consisting of two. The two support pieces 12, 12 are formed in the same shape, and each support piece 1
2 is a semi-circular semi-circular portion 13 and the semi-circular semi-circular portion 13
Arm 14 extending in the radial direction from the end of the arm.
In the case of the present embodiment, these two semicircular portions 13, 13 correspond to the mounting portion.

A rubber sheet 13a for absorbing vibration of the pipe joint 1 or preventing the pipe joint 1 from being damaged is mounted on the inner peripheral surface of the semicircular portion 13.

The semicircular portions 13, 13 of the two support pieces 12, 12 are applied from both sides of the upper socket 1a of the pipe joint 1, and the ends of the two 13, 13 are fixed to each other by fixing bolts 15, 13.
By the connection by 15, the two semicircular portions 13, 13 as attachment portions are fixed to the pipe joint 1, and thus the support 10 is attached.

The arm 14 has four mounting holes 14a.
To 14a are formed along the axis of the pipe joint 1.
Since the mounting holes 14a to 14a are formed at a pitch equal to or less than the diameter thereof, they are communicated with each other. However, the pitch of each of the mounting holes 14a to 14a is
Are set to communicate with each other in a range where they cannot pass through the mounting holes 14a to 14a. 4 provided in this way
The abutment bolt 11 is inserted into the mounting hole 14a arbitrarily selected among the mounting holes 14a to 14a.

Since the four mounting holes 14a to 14a are formed at a pitch equal to or less than the diameter thereof, the mounting bolts 11 are mounted at a finer pitch than when they are provided in an isolated state without communication. You can choose the position. On the other hand, since the butting bolt 11 cannot pass between the mounting holes 14a to 14a, the mounting position of the butting bolt 11 does not shift due to vibration or the like after being once mounted.

The abutment bolt 11 is inserted into the mounting hole 14a, and after adjusting the amount of downward projection from the arm 14, the fixing nuts 11a, 11a are used to adjust the amount of the abutment bolt 11.
Fixed to Below the butting bolt 11, a disc-shaped butting plate 11b is attached. The abutment bolt 11 thus configured is attached to the mounting hole 14a with the fixing nut 11a shown on the upper side in FIG. 1 being removed.
Is inserted from below, and then attached to the arm section 14 by tightening the upper fixing nut 11a.

Further, by changing the tightening position of the lower fixing nut 11a, the amount of protrusion of the abutment bolt 11 from the arm portion 14 can be adjusted, and after the adjustment, the upper fixing nut 11a is tightened. The butting bolt 11 is firmly fixed in a predetermined mounting hole 14a with a predetermined protrusion amount.

After the support 1 constructed as described above is attached to the upper receiving port 1a of the pipe joint 1, the pipe joint 1 is inserted into the slab hole Sa from the upper floor side as shown in the drawing, so that both ends are abutted. By fitting the bolts 11, 11 against the upper surface of the concrete slab S, the pipe joint 1 is set. In this state, by setting the amount of protrusion of the both butting bolts 11, 11 appropriately, the pipe joint 1 is moved. Positioning can be easily performed in the axial direction (vertical direction).

The inclination of the pipe joint 1 can be corrected by individually adjusting the amount of protrusion of the both butting bolts 11 and 11. The pipe joint 1 needs to be mounted vertically (the axis of the pipe is perpendicular to the concrete slab S). Therefore, as shown by a two-dot chain line in FIG.
The pipe joint 1 can be easily positioned at a correct position (vertical) even if the pipe joint 1 is inclined and opened.

Further, since the mounting positions of the abutment bolts 11 and 11 with respect to the arm portion 14 were not appropriate,
For example, when the abutting portion is located on the upper surface of the backfill portion (mortar M, slab hole Sa before backfilling), or other piping or the like is in the way, the abutting bolt 11 cannot be abutted. In this case, the mounting position of the butting bolt 11 can be changed.

To change the attachment position of the butting bolt 11 to the arm portion 14, the upper fixing nut 11a
, And once the butting bolt 11 is removed from the arm portion 14, this butting bolt 11 is attached to another mounting hole 14a.
And then tighten the upper fixed nut 11a.

In this manner, the butting bolts 11, 11
After adjusting the protrusion amount of the pipe joint 1 and positioning the pipe joint 1 with respect to the concrete slab S, the mortar M is poured into the slab hole Sa to perform backfill.

After backfilling, both butting bolts 11, 11 of the support 10 are abutted against the upper surface of the concrete slab S to support the pipe joint 1 in a suspended state. Rather, it is firmly supported by the support 10.

As described above, according to the support 10 of the present embodiment, the positioning of the pipe joint 1 with respect to the concrete slab S can be easily performed by adjusting the amount of protrusion of the both butting bolts 11 (11). Positioning function)
At the same time, after backfilling, the pipe joint 1 is supported in a suspended manner by the support tool 10, so that the pipe joint 1 can be strongly supported without relying only on the strength of the mortar M (support function).

Further, since a plurality of mounting holes 14a to 14a are formed in the arm portion 14 of the support 10, the mounting position of the butting bolt 11 can be changed arbitrarily. In the case where it is not possible to hit the butting bolt 11 against the concrete slab S due to, for example, the arm portion 14 of the butting bolt 11.
It can be easily handled by changing the mounting position with respect to.

Since the proof strength is low in the portion backfilled with the mortar M, it is desirable that the butting bolt 11 is butted against the concrete slab S, and this case can be easily dealt with.

Next, various modifications can be made to the embodiment described above. For example, although the mounting holes 14a to 14a provided in the arm portion 14 are formed to communicate with each other at a pitch equal to or less than the diameter thereof, for example, as shown in FIG. 14
a 'to 14a' may be provided independently without communication. FIG. 5 shows a state in which the abutment bolt 11 is mounted in the mounting hole 14a '.

As shown in FIG. 3, the number of mounting holes 14a to 14a formed in each arm portion 14 is not limited to four, but may be five.
The number may be two or more. However, if the mounting hole is a long hole that is long in the direction in which the arm portion 14 extends (the radial direction of the semicircular portion 13), only one mounting hole may be used.
In the case of a long hole, it is not necessary to remove the butting bolt 11 from the arm portion 14 each time the position of the butting bolt 11 is changed.

Further, each arm portion 14 has a semicircular portion 13
Although the case where it is provided at the end portion is illustrated, for example, as shown in FIG. 4, it may be provided at the arc portion (other than the end portion) of the semicircular portion 13, and the support piece 12 on one side is limited to one place Without
The arm portions 14 to 14 may be provided at two or more locations. Arm portions 14 are provided at three or more locations on support pieces 12 on both sides.
By providing the positions 14 to 14, finer positioning can be performed with respect to the inclination of the pipe joint 1 in all directions.

In the embodiment described above, the simple insertion hole 14a (14a ') is exemplified as the mounting hole. However, as shown in FIG. 6, for example, there are screw holes 14b to 14b into which the abutment bolt 11 can be screwed. You may. In this case, the protrusion amount can be adjusted by loosening the upper and lower fixing nuts 11a and 11b and rotating the butting bolt 11. Also in this case, each screw hole 14b to
14b can communicate.

Further, while the abutment bolt 11 is exemplified as the abutment member, an abutment rod 16 may be used instead, for example, as shown in FIG. In this case, as shown in the drawing, the abutment rod 16 has a plurality of fixing holes 16a to 16a along its axis, while the mounting holes 14a 'to 14a' have insertion holes 14c in the radial direction.
To 14c, the butting rod 16 is inserted into the appropriately selected mounting hole 14a ', and the fixing pin 17 is inserted into the fixing hole 16a of the butting rod 16 through the insertion hole 14c. What is necessary is just to make it the structure attached. Fixing hole 16a for inserting fixing pin 17
By selecting 16a, the amount by which the butting rod 16 projects downward from the arm portion 14 can be adjusted stepwise.

Further, although a two-part structure composed of two sets of support pieces 12, 12 each having a semicircular part 13 and an arm part 14 has been exemplified, it may be an integral type as shown in FIG. 8, for example. In the case of the support 20, a plurality of fixing bolts 22 to 22 are provided on the ring-shaped mounting portion 21 at appropriate intervals in the circumferential direction, and a rubber sheet 22 a for absorbing vibration is attached to the tip of each fixing bolt 22. Press plate 2 attached
2b, the fixing plate 22 is tightened, and the pressing plate 22b is pressed against the upper receiving port 1a of the pipe joint 1, so that the mounting portion 21 and thus the support tool 20 may be mounted. Even in this case, a plurality of arms 14 to 14 are provided on the mounting portion 21 so as to project outward, and a plurality of mounting holes 14 a to 14
14a may be provided.
