Description

  The present invention relates to a pipe fixing bracket for fixing a pipe with a constant gradient.

  In general, in a detached house in a cold region, in order to prevent water remaining in the piping from freezing and damaging the piping in the winter, water remaining in the piping in the middle of the water supply and hot water piping to the outside A drain plug for draining is provided. And the pipe from the end of the faucet to the drain faucet has a downward slope toward the faucet so that when the drain faucet is opened, the water remaining in the pipe is drained. It is laid. Therefore, the pipe from the end of the faucet device to the drain plug needs to be fixed by changing the height at an arbitrary position in the laying direction.

  As a fixing bracket that can fix the pipe by changing the height in consideration of such a drainage gradient, a base to which a pair of bolts are connected is fixed to the floor under an anchor and slid in the vertical direction across the pair of bolts. There has been proposed a structure in which a pipe is sandwiched between a support band and a fixed band that are movably inserted and fixed with a pair of lock nuts that are screwed into bolts at the top and bottom of the support band and the fixed band (for example, Patent Documents) 1).

Further, there is also known an apparatus in which an arbitrary number of height adjusting members are fitted to adjust the height, and a pipe fixing member is attached to the height adjusting member (for example, see Patent Document 2).

  However, in the former fixing bracket, it is necessary to rotate a total of four lock nuts when adjusting the height and fixing the pipe, and there are disadvantages that the operation takes time and the operation becomes complicated. In addition, although the fixing strength is high, the number of parts is large and the cost is high. Therefore, the outer diameter is 40 mm or more, the pipe diameter is relatively large, and it is used for fixing pipes with its own weight. It is used for lightweight small diameter pipes. Not.

  Moreover, in the latter fixing bracket, the height can be easily adjusted and the accuracy of the height can be secured, but the thickness is different in order to adjust to an arbitrary height. It is necessary to prepare a height adjusting member, resulting in an increase in cost.

  The present invention has been made in view of such problems, and is an inexpensive pipe fixing that can fix a pipe simply and surely with a constant gradient and improve the accuracy of height adjustment of the fixed pipe. A metal fitting is provided.

The present invention is composed of a fixed leg member and a pipe holding member that can be fixed to the fixed leg member, and is used for fixing a relatively small-diameter water and hot water supply pipe in a space under a floor or a ceiling of a house in a cold district. The fixing leg member includes a plate-like main body portion and a pair of leg portions formed by bending the lower end portion of the plate-like main body portion back and forth with a width of about half and bending it at 90 degrees. Each leg is formed with a fixing hole, while a plurality of mounting holes for screwing the tube holding member to the plate-like main body are equidistant in the height direction and adjacent mounting holes are provided. It is formed partly continuously , and the interval between the mounting holes of the fixed leg member is 1/100 of the support interval recommended for securing the water draining gradient of the piping to be fixed. .

According to the present invention, the pipe fixing bracket is fixed to the floor or the like at a set interval, and the mounting holes of the fixing leg members are lowered one by one or raised one by one to fix the pipe holding member to the fixing leg member. Furthermore, the pipe is arranged at a constant downward slope or upward slope, specifically, 1/100 drainage by a simple operation of arranging the pipe over the front and rear pipe holding members and fixing the pipe with the pipe holding member. It can be laid easily and reliably on a slope. In addition, a plurality of fixing heights can be accommodated by a single pipe fixing bracket, and the cost becomes low. Furthermore, the adjacent mounting holes of the fixed leg member are partially continuous, so that it is possible to form a plurality of mounting holes at equal intervals depending on the diameter of the bolt shaft portion of the tube holding member. Become.

  The plurality of mounting holes of the present invention are preferably 3 or more and 15 or less. That is, in the case of a relatively small-diameter water / hot water supply pipe, assuming that the support interval is 1 m, the same pipe fixing bracket can be used to cope with 15 types of fixed heights even in a space with a side slightly over 15 m. Therefore, it is possible to construct the water supply and hot water supply pipes of a detached house with almost a single type of pipe fixing bracket.

  According to the present invention, it is possible to easily and reliably fix the pipe with a constant gradient, and to improve the accuracy of height adjustment of the fixed pipe.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show an embodiment of the pipe fixing bracket 1 of the present invention.

  The pipe fixing bracket 1 includes a fixed leg member 2 that can be fixed to a floor lower surface or a ceiling rear surface, and a pipe holding member 3 that holds the pipe and can be screwed to the fixed leg member 2.

  The fixed leg member 2 includes a plate-like main body portion 21 and a pair of leg portions 22 formed by dividing the lower end portion of the plate-like main body portion 21 back and forth with a width of about half and bending it at 90 degrees. Each part 22 is formed with a fixing hole 22a and can be fixed using an anchor or the like. The plate-like main body 21 is formed with a plurality of, specifically nine, attachment holes 21a for inserting a bolt shaft portion 33 of the tube holding member 3 described later at equal intervals in the height direction. Yes.

  The tube holding member 3 includes an attachment main body 31, a movable arm 32 extending from one end of the attachment main body 31, and an outer surface of the attachment main body 31 opposite to the extending direction of the movable arm 32. A cylindrical shaft-shaped support portion 311 is formed on the inner surface of the mounting main body portion 31 along the outer peripheral surface of the pipe.

  The movable arm portion 32 has elasticity, and can be bent using the connection portion with the attachment main body portion 31 as a fulcrum using the elasticity. The movable arm portion 32 is formed in a thin strip shape that can surround the outer peripheral surface of the pipe, and the inner peripheral surface is formed in a substantially cylindrical surface shape along the outer peripheral surface of the pipe. Further, a branch portion 323 is extended at the base portion of the movable arm portion 32 so as to form a cylindrical surface continuous with the support portion 311 of the attachment main body portion 31. Further, at the distal end portion on the outer surface side of the movable arm portion 32, there are a locking claw 321 for temporarily fixing the movable arm portion 32 along the outer peripheral surface of the pipe, and a locking claw 322 for fixing the movable arm portion 32 in parallel. It is installed.

  Corresponding to these locking claws 321 and 322, a locked portion 312 is formed at the end of the mounting body 31 opposite to the side where the movable arm portion 32 is extended. The locked portion 312 is configured by providing a receiving claw 312 b on the inner surface of an opening 312 a that penetrates the outer surface and the inner surface of the mounting main body 31. The opening 312a of the locked portion 312 is formed to a size that allows the movable arm portion 32 to be inserted, and the locking claws 321 and 322 of the movable arm portion 32 are locked to the receiving claw 312b. To get.

  On the other hand, a fixing means is constituted by a bolt shaft portion 33 provided on the outer surface of the mounting main body portion 31 and a nut 4 that can be screwed to the bolt shaft portion 33, and the bolt shaft portion 33 serves as a fixing leg member 2. The tube holding member 3 can be fixed to the mounting hole 21 a at an arbitrary height position of the fixed leg member 2 by being inserted into the mounting hole 21 a and screwing the nut 4 into the bolt shaft portion 33.

  Next, a procedure for fixing the pipe using the pipe fixing bracket 1 configured as described above will be described.

  First, the fixed leg member 2 is fixed to the floor or the like at a recommended interval corresponding to the diameter of the pipe to be used. Next, after the bolt shaft portion 33 of the tube holding member 3 is inserted into the uppermost mounting hole 21a of the fixed leg member 2 standing near the faucet device, the nut 4 is screwed into the bolt shaft portion 33, and the tube The holding member 3 is fixed to the fixed leg member 2. Hereinafter, the lower mounting holes 21a are selected one by one for the mounting holes 21a of the fixed leg member 2 toward the drain plug, and after the bolt shaft portion 33 of the tube holding member 3 is inserted, the bolts The nut 4 is screwed into the shaft portion 33, and the tube holding member 3 is fixed to the fixed leg member 2.

  If the pipe holding member 3 is fixed to each fixed leg member 2, the pipe is inserted and arranged over the movable arm part 32 of each pipe holding member 3, and the movable arm part 32 is bent so as to wrap the pipe. The locking claw 321 is locked to the receiving claw 312b of the locked portion 312 to temporarily fix the pipe. Next, after finely adjusting the mounting position of the temporarily fixed pipe in the axial direction, the movable arm portion 32 is further pushed toward the locked portion 312, and the locking claw 322 is received and locked to the claw 312b. Fix it. As a result, the pipe is surrounded and supported by the movable arm portion 32 and is fixed, so that the pipe is laid with a downward slope (water drain slope) from the water faucet device to the water drain tap toward the water drain tap. When the drain plug is opened, the water remaining in the pipe can be discharged to the outside.

  Specifically, in the case of a cross-linked polyethylene pipe used for a detached house, the support interval is 1 m. Therefore, the pitch of the mounting holes 21a for inserting the bolt shaft portion 33 of the tube holding member 3 is 1 m. 10 mm which is 1/100 of is preferable. Accordingly, the pipe is supported by the pipe fixing bracket 1 at an interval of 1 m, and the pipe holding member 3 is fixed by lowering the attachment holes 21a of the fixed leg member 2 one by one, that is, by 10 mm. Pipes are laid with a 1/100 drainage gradient.

  1 to 3, the outer diameter of the bolt shaft portion 33 is 14 mm, and the hole diameter of the mounting hole 21a is slightly larger than the outer diameter of the bolt shaft portion 33 so that it can be easily inserted. Therefore, the adjacent mounting holes 21a are partially continuous, but the bolt shaft portions 33 can be held so as not to fall in the respective mounting holes 21a.

  In the above-described embodiment, when a plurality of mounting holes 21a are formed in the plate-like main body portion 21 of the fixed leg member 2 at equal intervals corresponding to the outer diameter of the bolt shaft portion 33, adjacent to each other. However, when the outer diameter of the bolt shaft portion 33 is small, for example, when the outer diameter is 8 mm, the mounting hole 21a is partially formed as shown in FIG. It is formed separately without being continuous.

  Further, as shown in FIG. 5, the leg portion 22 of the fixed leg member 2 is formed by a plate-like leg portion separate from the plate-like main body portion, and the plate-like main body portion and the plate-like leg portion are welded. It may be a fixed leg member.

  As described above, according to the present invention, it is possible to easily and reliably lay a pipe with a certain gradient by using a single pipe fixing, and therefore it is possible to efficiently perform the laying operation of the water supply and hot water supply pipes. Become.
