Description

[Detailed Description of the Invention] Technical Field The present invention relates to a pipe fixing structure for fixing a pipe for transporting fluid to a concrete slab surface of an apartment complex.

BACKGROUND TECHNOLOGY When fixing pipes that are rolled on the floor, so to speak, to the concrete slab surface of an apartment complex, conventionally the pipes are fixed using a U band called a U band.
The base end of the letter-shaped fixing member is driven into the concrete slab surface using a concrete nail. Another prior art technique uses a vibration drill to drill a hole in a concrete slab surface, drives a curl plug into the hole, and fixes the base end of the U-shaped fixing member using a wood screw.

Problems to be solved by the invention In the prior art using concrete nails as described above, since the surface of the concrete slab is hard, it is difficult to drive the concrete nails accurately, and there is a problem that there are many failures when driving the concrete nails. be. Furthermore, after driving the concrete nails, the concrete nails float off the slab surface, making it impossible to support the U-shaped fixing member and therefore the pipe. Further, each of these prior art techniques requires a lot of labor, takes a long time to perform the construction work, and has a high risk of injury to workers.

In addition, as shown in FIG. 4, which will be described later, a roughly U-shaped fixing member 5 is used, and the outwardly projecting mounting portion of this fixing member is directly bonded to the concrete slab surface with an adhesive. It is also possible to fix it. At this time, the mounting portions 15, 1 of the U-shaped fixing member
If 6 is strongly pressed against the concrete slab surface, the layer thickness of the adhesive becomes smaller and the adhesive strength decreases. In particular, the surface of the concrete slab has minute protrusions and unevenness, so the adhesive force may be insufficient near the part where the attachment part comes into contact with the minute protrusions on the concrete slab surface. , the adhesive strength decreases. Furthermore, since the mounting portion of such a U-shaped fixing member has a relatively small shape, there is also a problem in that the adhesive strength is low.

An object of the present invention is to provide a pipe fixing structure that allows a pipe to be fixed to a concrete slab surface or the like using an adhesive with high adhesive strength.

Means for Solving the Problems According to the present invention, one surface of the metal flat plate-shaped substrate 4 facing the fixing position side is provided with a plurality of plates for forming an interval l1 between the plate and the fixing surface of the fixing position. Protruding pieces 6 are provided in a scattered manner, and each protruding piece is formed by partially punching out a roughly U-shaped portion of the base body 4, and each protruding piece 6 is a protruding piece extending toward the fixing surface. Part 6a
and an abutting part 6b that extends along the fixing surface and connected to the free end of the protruding part 6a, and a pair of engagement parts are provided on the other surface of the base body 4 opposite to the one surface. Stop pieces 10 and 11 are provided, and the tube 3 disposed on the other surface of the base 4 is connected to the semicircular curved portion 12 of the U-shaped fixing member 5 and from the curved portion 12 toward the base 4. A pair of extending legs 13, 14
and each mounting member 15, which is surrounded by and extends from the proximal end of the leg portions 13, 14 of the fixing member 5 in a direction away from each other.
16 are formed with insertion holes 17 and 18, respectively, and the locking pieces 10 and
11 are respectively inserted and locked, and an adhesive 20 is interposed between the fixing position and the one surface of the base body 4.

Effect According to the present invention, the metal flat base 4 has the following properties:
A plurality of protruding pieces 6 are provided in a scattered manner, and these protruding pieces 6
is formed by partially punching the base 4 into a roughly U-shape. The projecting piece 6 has a protrusion 6a extending toward a fixed surface such as a concrete slab surface, and a contact portion 6b extending along the fixed surface. Accordingly, due to the function of the protruding portion 6a, a gap l1 exists between the base body 4 and the fixing surface, and an adhesive layer having a desired thickness is interposed therebetween. Therefore, the base body 4 can be fixed to a fixed surface such as a concrete slab surface with a large adhesive force. Therefore, even when the base 4 is strongly pressed against the fixed surface with the adhesive interposed, the gap 11 exists, and the adhesive layer of the desired thickness allows the base 4 to be pressed against the fixed surface with great strength. It is possible to fix it. Such adhesive strength can be determined depending on the size of the base 4, and a desired high adhesive strength can be obtained.

Furthermore, since a plurality of protrusions 6 are provided, the base body 4 can be arranged, for example, approximately parallel to the fixed surface, and the thickness of the adhesive layer can be made uniform, thereby increasing the adhesive strength.

Furthermore, since there is a distance l1 between the base body 4 and the fixed surface, even if the fixed surface has many fine irregularities, such as a concrete slab surface, the , adhesive strength can be reliably achieved with the adhesive.

Furthermore, since the protruding piece 6 has an abutting part 6b connected to the free end of the protruding part 6a, when the abutting part 6b catches the adhesive after bonding, the base 4
is prevented from peeling off from the fixed surface.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention.
A copper pipe 3 coated with a heat insulating material 2 for hot water supply, hot water heating, etc. is fixed to a concrete slab surface 1 of an apartment complex. According to the invention, for fixing this tube 3, a base body 4 and a U-shaped fixing member 5, called a U-band, are used.

FIG. 2 is a perspective view of the base 4, and FIG. 3 is a front view of the base 4. The base body 4 has a thickness of 0.5 to 1
It is made of stainless steel, etc., and is basically plate-shaped. This base body 4 is formed with a plurality of (six in this embodiment) projecting pieces 6 that project toward the concrete slab surface 1 side. The projecting piece 6 is formed by plastically deforming a punched portion of the roughly U-shaped punched portion 7 of the base body 4. This projecting piece 6 projects by a length l1 from one surface 4a of the base body 4 facing the concrete slab surface 1. As a result, a distance l1 is formed between the surface 4a of the base body 4 and the concrete slab surface 1.

The protruding piece 6 has a protruding portion 6a extending toward the concrete slab surface 1, and an abutting portion 6b extending along the concrete slab surface 1 in connection with a free end portion of the protruding portion 6a.

A pair of locking pieces 10 and 11 are also formed on the base body 4. The locking pieces 10 and 11 protrude from the roughly U-shaped punched portions 8 and 9 of the base body 4 toward the other surface 4b of the base body 4, and are plastically deformed. The base body 4 on which the protruding piece 6 and the locking pieces 10 and 11 are formed in this manner is configured to be plane symmetrical with respect to a plane of symmetry passing through the locking pieces 10 and 11.

As shown in FIG. 4, the U-shaped fixing member 5 has a semicircular curved portion 12 surrounding the heat insulating material 2.
and the concrete slab surface 1 from the curved part 12
leg portions 13, 14 extending to
It has attachment parts 15 and 16 extending outward from the base end in a direction away from each other, and is made of stainless steel with a thickness of about 0.5 to 1 mm. The mounting portions 15 and 16 have insertion holes 1 through which the locking pieces 10 and 11 are inserted.
7 and 18 are formed.

When fixing the pipe 3 coated with the heat insulating material 2 to the concrete slab surface 1,
The substrate 4 is placed at the position. The surface 4 of the substrate 4 due to the function of the projections 6 formed on the substrate 4
There is a distance l between a and the concrete slab surface 1.
1 is formed. This gap l1 is filled with an adhesive 20 such as so-called concrete bond. Thereby, the substrate 4 is reliably adhered and fixed to the concrete slab surface 1. Since the protruding piece 6 forms the gap l1 between the surface 4a of the substrate 4 and the concrete slab surface 1 as described above, this gap l1 is filled with adhesive, and the protruding piece 6 is wrapped in the adhesive. By doing so, the adhesive 20 can adhere and fix the substrate 4 to the concrete slab surface 1 with a uniform thickness. In this way, the substrate 4 can be fixed to the concrete slab surface 1 with sufficiently high strength.

Insertion holes 17 and 18 formed in the attachment parts 15 and 16 of the U-shaped fixing member 5 surrounding the heat insulating material 2
The locking pieces 10 and 11 are inserted through the holes. Locking piece 1
0 and 11 are bent as indicated by reference numerals 10a and 11a in FIG. 1, thereby preventing the U-shaped fixing member 5 from detaching from the substrate 4. In this way, the tube 3 is securely fixed to the concrete slab surface 1. According to such an embodiment, workability is good, the pipe 3 can be reliably fixed to the concrete slab surface 1, and it is safe.

FIG. 5 is a sectional view of another embodiment of the present invention. This embodiment is similar to the previous embodiment and corresponding parts are provided with the same reference numerals. In this embodiment, a tube 23 with passages 21, 22 for transporting fluid
is surrounded by a generally U-shaped fixing member 24, and the proximal ends 25, 26 of this fixing member 24 are fixed to the base body 4 in the same manner as in the previous embodiment. The base body 4 is fixed to the concrete slab surface 1 by an adhesive 20.

The invention can be broadly implemented with respect to conduits that transport fluids such as gases and liquids.

Effects As described above, according to the present invention, an adhesive is interposed in the interval formed by the protrusion between a fixed surface at a fixed position such as a concrete slab surface and one surface of the base, This securely adheres and fixes the base at the fixed position. A tube is fixed to the base by fixing means. In this way, the pipe can be reliably fixed at the fixed position with a simple operation, and there is no risk of injury to the operator, making it safe. In particular, according to the present invention, the base body 4 is fixed to a fixed surface such as a concrete slab surface using an adhesive, and the pipe 3 is attached to this base body 4 by the U-shaped fixing member 5, so that the surface area is large. This makes it possible to bond and fix the base 4 to the fixing surface, thereby improving the adhesive strength.

Further, according to the present invention, since the base body 4 is provided with a plurality of protrusions 6 scattered, the base body 4 can be arranged on the fixed surface, for example, almost parallel, and between the base body 4 and the fixed surface. A spacing l1 can be formed, thus ensuring that a layer of adhesive is formed between the base body 4 and the fixing surface to fix the base body 4 to the fixing surface. This also makes it possible to improve the adhesive strength of the adhesive to the fixed surface of the base 4.

Moreover, since the adhesive is interposed in this interval l1, even if the fixing surface has many minute protrusions, such as a concrete slab surface, the base body 4 can be reliably bonded to the fixing surface.

Moreover, the protrusion piece 6 has a protrusion part 6a and a contact part 6b bent from the protrusion part 6a, and this contact part 6b
is in contact with the fixed surface, and the distance l1 is maintained by the protrusion 6a.
is formed, so that an adhesive layer is reliably formed between the base 4 and the fixed surface, and
The contact portion 6b will be caught by the adhesive after adhesion, and therefore the base body 4 will be reliably prevented from peeling off from the fixed surface.

In this way, adhesive is applied to the lower surfaces in FIG. 4 of the attachment parts 15 and 16 of the U-shaped fixing member 5 in FIG. In comparison, it is understood that according to the present invention, it is possible to significantly improve adhesive strength. Note that such a configuration in which the fixing member 5 is bonded to the concrete slab surface with an adhesive has not been put to practical use because its adhesive strength is low. The present invention solves these problems.
