DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single pipe (outer diameter) used for assembling a scaffold in construction work and civil engineering work.
48.6mm).

[0002]

2. Description of the Related Art Single-pipe pipes may be thrown from a high place or dropped from a high place during scaffolding or scaffold disassembly. In these cases, the pipes collide with each other and emit high metal sounds. In addition, it may cause a noise problem, and may cause an unexpected accident by rolling on the ground after being thrown and falling.

[0003] At present, there is no product which aims to simultaneously solve the noise problem of the single pipe and to prevent the above accidents, but recently, pipes intended to protect the safety of various pipes have not been found. Protective cover (trade name / trapipe) is commercially available.

[0004] This pipe protection cover is a product developed to ensure a danger display function and pipe protection functions such as heat insulation, cold insulation, and water resistance of the pipes, and is therefore made of polyethylene resin foam. A vinyl chloride resin film on which yellow and black oblique stripes are printed is integrally fixed to the entire surface of the pipe body, and a bellows having a binder is formed in the length direction of the pipe body.

[0005] The pipe protective cover is made of polyethylene resin foam as described above. Therefore, when it is attached to a single pipe, it may be possible to solve the noise generation problem. Single pipe,
Since the rolling of the dropped single pipe cannot be prevented, an unexpected accident due to the rolled single pipe cannot be prevented.

The pipe protective cover may be easily attached to a single pipe by using a bellows having a binder, but once attached, the bellows are joined with the binder. It cannot be easily removed, and there is a problem in usability.

Further, since the pipe body is made of a polyethylene resin foam as described above, the pipe protective cover is inevitably thick, bulky, and has a problem of storage space. doing.

In addition to the pipe protective cover described above, FIG.
A band-type clamp member having a structure as shown in FIG. 8 is known. (See, for example, Japanese Utility Model Laid-Open No. 48-38274.) In this clamp member, a band a'1 is made of an elastic material such as rubber, and an inclined projection a'2 integrally formed at one end of the band is provided at the other end. It is configured to engage with the engagement hole a'3.

Since the band-type clamp member is narrow in width and has the configuration disclosed in the publication, even if it is wound around a single pipe, the exposed area of the pipe becomes large, and the thrown single pipe pipe However, there is a concern that the exposed surfaces of the dropped single pipes may collide with each other and generate noise, which does not contribute much to solving the noise generation problem.

Therefore, when the width of the clamp member is increased, the inclined protrusion a'2 and the engagement hole a'3 are increased by the increased width.
It is necessary to increase the number of arrangements to ensure reliable engagement of both ends of the band a'1.
Every time the pipe is attached to or detached from the single pipe, a lot of inclined projections a'2 must be engaged with a lot of engagement holes a'3, which causes a problem in usability.

When the band-type clamp members are stored in a stacked state, the inclined projections a'2 are liable to be distorted, thereby preventing the engagement of the inclined projections a'2 with the engagement holes a'3. There is a possibility that the work with the person outside the company becomes difficult.

Further, the above-mentioned clamp member comprises a band a '
Since there is no projection other than the inclined projection a'2 in Fig. 1,
Even if the pipe is wound around a single pipe, the inclined projection a'2 alone is not enough to prevent the pipe from rolling. There is a concern that the occurrence cannot be prevented.

According to the present invention, the notch clip formed by the pair of arms b'1 and b'2 as shown in FIG. Nail b '
4 and b'5, a clip configured to sandwich an elastic rib is known (for example, Japanese Utility Model Laid-Open No. 52-4441).
In the case of a single pipe thrown or dropped, there is little fear of rolling,
Accordingly, it is an object of the present invention to provide a single-pipe pipe soundproofing device which is less likely to cause an unexpected accident due to rolling of the single-pipe.

[0014] Another object of the invention is to provide a single tube pipe that is thrown or dropped and hits each other or the ground.
An object of the present invention is to provide a soundproofing device for a single pipe with less concern for noise generation.

Another object of the present invention is to provide an easy-to-use single-pipe pipe soundproofing device that can be easily attached to and detached from a single-pipe pipe. Still another object of the present invention is to provide a soundproofing device for a single pipe that is hard to fall off from the single pipe even when the pipe is thrown or dropped when attached to the single pipe. .

In order to prevent the formation of a step (a step in the radial direction of the buffer tube 1) on the bottom outer surface facing the outer member 2a, the bottom of the outer member 2a has a shape lacking in an L-shape in a front view from the outer surface side. Then, a concave portion 15 is formed in the L-shaped portion.

The projection 14 of the inner member 2b of the second example is formed on the bottom surface facing the outer member 2a (the surface facing the buffer tube 1 in the circumferential direction). In order to prevent a step (a step in the radial direction of the buffer tube 1) from being formed on the bottom outer surfaces of the both members (the bottom outer surface facing the cut 3) when the two members are incorporated, the bottom of the inner member 2b is formed. Is formed into a shape L-shaped as viewed from the front from the side of the facing surface, and a protrusion 14 is protruded from the L-shaped part.

When the rolling prevention portion 2 is formed by assembling the outer member 2a and the inner member 2b of the second example, if the step is formed on the bottom outer surface, the buffer provided with the rolling prevention portion 2 is provided. The stepped portion collides with another object due to throwing, dropping, or the like of the single tube pipe to which the shock-absorbing tube 1 provided with the elastic tube 1 or the rolling prevention portion 2 is attached, and the projection 14 And the recess 15 are disengaged, and there is a concern that the rolling prevention portion 2 is disassembled into the outer member 2a and the inner member 2b, so that no step is formed on the bottom outer surfaces of both members 2a and 2b as described above. The rolling prevention unit 2 is configured as described above.

Next, the means for assembling the outer member 2a and the inner member 2b for constituting the rolling prevention portion 2 will be described. Before attaching the buffer tube 1 to a single pipe (not shown), Shock absorbing tube 1 at the height side wall of member 2a
And the inner surface on the bottom (the inner surface on the side opposite to the cut 3)
After contacting the outer surface of the buffer tube 1 and the opposing surfaces of the opposing edges of the cut 3, respectively, the projections 14 of the inner member 2b are engaged with the recesses 15 of the outer member 2a and incorporated into the rolling prevention portion 2. To form Further, after the buffer tube 1 is attached to a single pipe (not shown), a part of the opposite edge of the cut 3 is separated from the single pipe so that a part of the buffer tube 1 is removed. The outer member 2a and the inner member 2b are assembled and attached to the detached portion by the above-described assembling means, and the rolling prevention portion 2 is provided.

The fact that the anti-rolling portion 2 of this configuration is difficult to fall off from the buffer tube 1 and that the incorporated outer member 2a and inner member 2b are hard to disassemble is the same as the outer member 2a of the first example. Anti-rolling part 2 constituted by inner member 2b
In the same case, the description is omitted.

The means for attaching the buffer tube 1 to a single pipe (not shown) is the same as that of the first example of claim 2 irrespective of whether or not the rolling prevention portion 2 is provided. Since there is, duplicate explanation is omitted.

In all the embodiments described above, when the single pipe P to which the buffer pipe 1 is attached is thrown,
Considering the length configuration and usage of the buffer tube 1 in terms of soundproofing when dropped, etc., the tube is constructed to have the same length as the single pipe P and attached to the pipe. For example, it is possible to completely achieve the soundproofing purpose, but when assembling the scaffold, the buffering tube 1 and the anti-rolling part 2 may be in the way, and the assembly work may not proceed as expected. It is conceivable that the cost of the tube increases.

Accordingly, the length of the buffer tube 1 is 5 to 50.
In order to minimize the exposed dimension or exposed area of the single pipe P, select an appropriate number of buffering pipes 1 in the single pipe P at short intervals. It is preferable to use it by attaching to it.

[0154]

Since the present invention has been configured as described above,
The following effects are exhibited. As an effect common to all claims,
Attaching one or more suitable number of buffer tubes to a single pipe reduces the risk of high metal noise even if the pipes hit each other or the pipe hits another object. Therefore, it can contribute to the prevention of noise generation by the single pipe. As an effect common to all the claims, the single pipe to which the buffer pipe is attached is hardly rolled by the anti-rolling portion of the buffer pipe. Therefore, it is not least helpful to prevent unexpected accidents caused by rolling of the single pipe.

According to the second aspect, if the buffer tube is expanded from the cut, it can be easily attached to and detached from the single pipe. Therefore, the buffer tube can be efficiently attached to and detached from the single pipe.

According to a third aspect, the anti-rolling portion is attached to the shock absorbing tube and can be removed. Therefore, regardless of the state in which the anti-rolling part is attached to or detached from the shock absorbing tube, storage and transportation can be performed conveniently.

According to a fourth aspect, the stopper prevents the buffer tube attached to the single pipe from easily falling off. Therefore, the single pipe can be securely held by the buffer pipe, and the functions of the soundproofing and the rolling prevention can be surely exhibited. Then, if the shape of the stopper is formed into a shape that does not easily roll, it can be used also as a rolling prevention part.
Therefore, if a stopper having a shape that does not easily roll is attached to the buffering tube attached to the single pipe, it is useful to prevent the single pipe from rolling.

[0158] A fifth aspect of the present invention is that the insertion plate having the anti-rolling portion is inserted into the insertion groove of the shock-absorbing tube attached to the single-tube pipe, and the anti-rolling portion allows the single-tube pipe to be inserted. And the buffer tube becomes difficult to roll, and the insertion plate functions as a stopper. Therefore, it contributes to prevention of unexpected accidents caused by rolling of the single pipe and holding of the single pipe by the buffer pipe.

According to a sixth aspect of the present invention, the buffer tube provided with the first anti-rolling portion having the insertion groove is attached to a single pipe.
If the insertion plate having the second rolling prevention unit is inserted into the insertion groove, the single pipe and the buffer tube are rolled by the first rolling prevention unit and the second rolling prevention unit. It becomes difficult, and the insertion plate functions as a stopper. Therefore, there is an effect that unexpected accidents are prevented from occurring due to the rolling of the single pipe, and the single pipe is held by the buffer pipe.

According to a seventh aspect of the present invention, the anti-rolling portion is provided at the opposing edge of the cut before or after the mounting of the buffering tube to the single pipe, so that the rolling of the single pipe and the buffering tube is performed. Prevention becomes possible. Therefore, an effect of preventing occurrence of an unexpected accident due to rolling of the single pipe is exhibited.
