DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to examples. FIG. 1 is an explanatory view of an embodiment of a method for fixing a pipe suspension according to the present invention, FIG. 2 is a perspective view illustrating a locking aspect of a wire 10 in the embodiment, and FIGS. FIG. 5-7 is a perspective view illustrating a locking mode of the wire 10 in the embodiment, and FIG. 8 is an explanatory view of another embodiment of the method for fixing a piping hanger according to the present invention. .
[0008]
First, based on FIG. 1, the Example of the fixing method of piping hanger is described. FIGS. 1A and 1B illustrate a method for fixing a piping hanger using a cross-sectional view. FIG. 1A shows a state before placing concrete 3, and FIG. 1B shows a state where wires 10 are attached to a deck plate 1. , (C) is a state in which the concrete 5 is cast and the floor slab 7 is formed.
[0009]
First, as shown to Fig.1 (a), before placing concrete which forms a floor slab in the arrange | positioned deck plate 1, the through-hole 2 is drilled using a drill etc. As shown in FIG. As the deck plate 1, a corrugated plate made of steel is usually used. However, any material can be used as long as it can function as a floor mold, and the material, shape, and the like are not particularly limited. The through-hole 2 is sized such that the wire 10 to be inserted in a later process can be inserted. Depending on the outer diameter of the wire 10 and the locking means of the one end 11 of the wire 10, for example, If the diameter is about 1.2 mm, it is usually only about 2 to 3 mm. The work of making the through hole 2 is usually performed by an operator on the deck plate 1, but the through hole 2 is provided in the deck plate 1 in advance, and the deck plate 1 may be disposed. Good.
There are two types of floor formwork methods using a deck plate: a case where the deck plate is used as a temporary material, and a case where the deck plate is used as a composite structure as a component of the floor slab. The present invention is preferable in the latter case. Applicable, but applicable to the former case.
[0010]
Next, as shown in FIG. 1 (b), one end 11 of the flexible wire 10 is locked to the upper side of the deck plate 1 in the through hole 2, and the wire 10 is inserted through the other end of the wire 10. The part 12 is hung below the deck plate 1. The other end 12 of the wire 10 forms a free end.
The wire 10 which is a piping hanger has flexibility and elasticity, and a metal made by twisting is preferable in terms of strength. Moreover, those made of stainless steel having excellent rust prevention performance are preferably used. The diameter of the wire 10 is preferably about 1 mm in the case of a stainless steel one, for example, in the suspension of a normal air-conditioning duct, in terms of strength, handleability, and cost.
In addition, the wire 10 is preferably formed by coating the surface of a metal wire with a synthetic resin or other antirust material. For example, a metal wire whose surface is covered with a tube of vinyl chloride resin or other synthetic resin is used. The rust preventive material may not be a synthetic resin as long as it has a rust preventive function, and a known appropriate means can be adopted as the covering means.
[0011]
Various means can be adopted as means for locking the one end 11 of the wire 10 to the upper side of the deck plate 1. For example, the wire 10 for suspending pipes can be locked using a wire provided with a locking portion at one end 11 thereof.
In FIG. 1, the one end 11 of the wire 10 is formed in a ring shape as shown in FIG. 2, and a locking portion is provided. A locking tool 20, which is a rod-like body such as a cutting bolt, is inserted so that one end 11 of the wire 10 is locked to the upper side of the deck plate 1.
[0012]
In this embodiment, the ring-shaped portion of the one end portion 11 of the wire 10 is formed by using a crimp sleeve 15 as a stopper as used for forming a crimp terminal as shown in FIG. The wire 10 is passed through the crimping sleeve 15, the end of the wire 10 is bent to the opposite side to form a ring, the end is inserted into the crimping sleeve 15 and bundled, and the crimping sleeve 15 is crushed using a crimping tool as appropriate. Thus, the one end portion 11 of the wire 10 is fixed in a ring shape. The one end 11 of the wire 10 may be formed in a ring shape in this manner, as it may be used by carrying it in advance at a construction site or by an operator at the construction site. Good.
Then, the one end 11 of the wire 10 is locked to the upper side of the deck plate 1, the wire 10 is inserted into the through hole 2, and the other end 12 of the wire 10 is hung below the deck plate 1. The attachment work to the deck plate 1 is completed.
[0013]
Next, as shown in FIG. 1 (c), by placing concrete 5 on the deck plate 1, the one end 11 of the wire 10 is buried and fixed inside the concrete 5 of the floor slab 7, and the wire 10 Fixing of the piping hanger using is completed. Unlike the anchor bolt, the wire 10 hanging below the deck plate 1 has flexibility, so there is no danger of injury and the safety is high.
[0014]
After the fixing of the wire 10 to the floor slab 7 is completed, the work of suspending the piping 50 is performed using the other end portion 12 of the wire 10. These work and the connection aspect of the other end part 12 of the wire 10 and the piping 50 can use a known appropriate means, and are not limited at all.
For example, as shown in FIG. 3, the other end portion 12 of the wire 10 is passed through the upper through hole provided in the suspension band 60 having an appropriate structure surrounding the outer periphery of the piping 50, as described above. The other end 12 of the wire 10 and the piping 50 can be connected using the crimp sleeve 15 or other stoppers.
Also, for example, as shown in FIG. 4, the other end 12 side of the wire 10 is wrapped directly around the outer periphery of the piping 50 and fixed using the crimping sleeve 15 or other stopper as described above. Then, the other end 12 of the wire 10 and the piping 50 can be connected.
[0015]
In the method for fixing a piping hanger according to the present invention, it is desirable to use a plurality of types of color-coded wires and fix wires of different colors according to the piping system. For example, to distinguish between air ducts and refrigerant pipes, water pipes and other equipment pipes, and to distinguish between air conditioning duct pipe types (for example, main pipes and branch pipes), these pipe systems (types) In a corresponding manner, color-coded wires 10 are used and fixed. In this way, when the work of hanging the pipes on the wire 10 is performed later, the piping system can be identified instantaneously, and the piping can be performed quickly and reliably. As described above, since the wire 10 can be made by coating the surface of a metal wire with a vinyl chloride resin or other synthetic resin, the wire 10 of a different color is easy to manufacture and does not cost.
[0016]
As a means for locking one end portion 11 of the wire 10 to the upper side of the deck plate 1, another aspect will be described with reference to FIGS. 5 to 7, the configuration of the wire 10 is such that one end 11 of the wire 10 is formed in a ring shape, and is basically the same as that already described with reference to FIGS. The description is omitted.
[0017]
5 is the same as that shown in FIGS. 1 and 2 in that the one end 11 of the wire 10 is engaged and locked with another locking tool. However, the difference is that a washer (plate-like body) (20) having a through hole 21 in the center is used as the locking tool 20. The through hole 21 has a diameter slightly larger than the outer diameter of the wire 10. The other end 12 of the wire 10 is inserted into the through hole 21 of the washer (20) and then inserted into the through hole 2 of the deck plate 1. As a result, the ring-shaped portion (or the crimp sleeve 15) of the one end portion 11 of the wire 10 is locked to the washer (20) on the upper side of the deck plate 1.
[0018]
In FIG. 6, one end 11 of the wire 10 is locked to the upper side of the deck plate 1 without using another locking tool, and the wire 10 is inserted into the through hole 2, and the other end of the wire 10 is inserted. The end 12 is hung below the deck plate 1.
The through hole 2 formed in the deck plate 1 is formed in a size that allows the ring-shaped portion (or the crimp sleeve 15) of the one end portion 11 of the wire 10 to be just locked, and the other end portion 12 of the wire 10 is formed. Then, it passes through the through hole 2 of the deck plate 1 as it is. As a result, the ring-shaped portion (which may be the crimp sleeve 15) of the one end portion 11 of the wire 10 is locked to the deck plate 1 on the upper side of the deck plate 1.
[0019]
FIG. 7 shows an example in which one end 11 of the wire 10 is locked to the reinforcing bar 8 arranged in the floor slab 7. As shown in FIG. 7 (a), a wire 10 is locked to the deck plate 1 using a reinforcing bar 8 arranged in the floor slab 7, and the wire 10 is inserted into the through-hole 2 to The other end 12 of 10 is suspended below the deck plate 1. In this embodiment, the reinforcing bar 8 is inserted into the ring-shaped portion of the one end portion 11 of the wire 10. Usually, a ring-shaped portion of the wire 10 is formed by winding the reinforcing bar 8 at a construction site, and the locking member such as the crimping sleeve 15 is used as a locking portion of the wire 10 to be locked to the reinforcing bar 8. Then, as shown in FIG. 7 (b), by placing the concrete 5, the ring-shaped portion of the one end portion 11 of the wire 10 is arranged in the floor slab 7 on the upper side of the deck plate 1. It will be in the state locked by.
Since the wire 10 has flexibility, even when there is no reinforcing bar 8 at a position directly above the through hole 2 that should be provided at a predetermined position in order to suspend the pipes, the wire 10 is locked to the nearby reinforcing bar 8 and the through hole is provided. Because it can lead to 2, it is very convenient.
[0020]
FIG. 8 shows a method of fixing a piping hanger corresponding to claim 2.
[0021]
In this fixing method, first, as shown in FIG. 8A, two through holes 2 and 2 are formed in the deck plate 1 with an appropriate interval L therebetween. The space | interval L can be suitably set as needed.
Next, as shown in FIG. 8B, before placing the concrete forming the floor slab, the end portions 11 and 12 of the flexible wire 10 are placed in the through holes 2 and 2 of the deck plate 1. The end portions 11 and 12 of the wire 10 are suspended below the deck plate 1 through the through holes 2 and 2.
Next, as shown in (c), by placing the concrete 5 on the deck plate 1, the intermediate portion 13 of the wire 10 can be embedded and fixed inside the concrete 5 of the floor slab 7.
This fixing method does not require any processing on the wire 10. Further, the two wires 10 hanging below the deck plate 1 can be used for suspending one pipe, and can also be used for suspending different pipes.
