  However, conventional protective members are designed on the premise that they are laid on the protected member in the middle of construction or directly buried in the construction site, and it is assumed that the protected member will be protected during the transportation. There wasn't. In particular, in the construction method of the vibration isolation wall using the cushion body, which is required to be expanded in advance at the factory, it is permanent not only during transportation from the factory to the construction site, but also during construction and after construction. In order to maintain the cushion body having a predetermined performance, it is necessary to protect the cushion body. However, there has been no protective member that satisfies this requirement.

  Then, an object of this invention is to provide the protection member which protects a cushion body also during conveyance from a factory to a construction site, the middle of construction, and after construction.

In order to solve the above-mentioned object, the protective member of the present invention comprises a first surface and a second surface facing each other, and an openable and closable opening on one side of the first surface and the second surface. A bag-shaped main body sewn so as to form a closed portion on each side, and an extending portion formed on both sides of the first surface and the second surface of the portion forming the opening of the main body, A first locking means formed on each edge of the opening of the first surface and the second surface in the short direction, and in a state where the protected member is accommodated in the bag-shaped body, wherein the extended portion of the first surface, wherein the extended portion which is formed on the second surface are overlapped with each other, and a first locking means of the first locking means and the second surface of the first side with each other The opening is closed by being locked.

  According to the protective member according to the present invention, the cushion body, which is a member to be protected, can be protected even during transportation from the factory to the construction site, during construction, and after construction. In particular, in the process of being buried in the fluidized ground after the construction, it is possible to prevent the cushion body, which is a member to be protected, from being damaged by gravel or stone in the soil. Even when protecting a plurality of coupled cushion bodies, the protective members are overlapped with each other on both the opening side and the closing side of the protective member, and then locked with a removable surface fastener or the like. It is possible to prevent gravel and stone in the soil from coming into contact with the protected member. Moreover, since the internal cushion body can be prevented from being deformed by a temperature change by configuring the bag-like protective member with a member having low thermal conductivity, the cushion body can maintain a predetermined vibration isolation performance for a long period of time. .

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

  FIG. 1 is a perspective view of a protective member according to the present invention. The protective member 1 for protecting the cushion body is a schematic bag formed by folding a sheet of a generally rectangular reinforcing cloth at a folded portion F and fixing a part in the longitudinal direction and the lateral direction to each other by sewing or the like. Shape. As can be understood from FIGS. 1 and 2, the bag-shaped protection member 1 has an opening A that can be opened and closed by first and second locking means described later from the point O on the upper side in the drawing, and the lower side in the drawing. It is a blockage. In the following, reference numeral L indicates a sewing part.

  More specifically, the protection member 1 includes a first surface (back surface) 5a located in front of the paper surface in FIG. 1 and a symmetrical second shape located on the opposite side of the first surface 5a via the folded portion F. It consists of a surface (surface) 5b (see FIG. 2). Further, as shown in FIG. 3 (a), in order to ensure strength at the sewing portion L, two places are sewn after the first surface 5a and the second surface 5b are folded back.

  In this way, by forming a protective member 1 by folding back one long reinforcing cloth, the number of parts to be sewn can be reduced, so that foreign matter such as gravel and stone can be efficiently introduced during construction. Can be prevented.

The extending portions 10a and 10b are respectively provided at positions separated from the upper ends in the longitudinal direction of the first surface 5a and the second surface 5b of the portion where the opening A is formed by a predetermined length. Moreover, the short side direction from the upper end of the extension part 10a (10b) to the upper end of the 1st surface 5a and the 2nd surface 5b is the latching | locking part 11 in which the 1st latching means mentioned later was provided. .

More preferably, as shown in FIGS. 1 and 2, the extending portion 10a (10b) is when it is fixed to the protection member 1, via the second locking means and the like ladder belt 12 described later Fixed.

FIG.3 (e) is sectional drawing which shows a mode that the extension part 10a (10b) was attached. As can be understood from the drawing, a portion having a three-layer structure of the ladder belt 12, the first surface 5a (second surface 5b), and the extending portion 10a (10b) is sewn. Moreover, in order to ensure intensity | strength, it is preferable that the edge part of the 1st surface 5a (2nd surface 5b) and the extension part 10a (10b) is folded in the sewing part L. FIG.

  In this embodiment, after a protected member (cushion body) (not shown in FIGS. 1 to 3) is accommodated in the protective member 1 in the factory, the protected member does not come out of the protective member 1 during transportation. In order to do so, a single surface fastener Ma, Mb is provided in the locking part 11 as a locking means (first locking means) for closing the lateral direction of the opening A. In FIGS. 1 and 2, Ma is a male surface fastener, and Mb is a female surface fastener. Of course, the male Mb may be provided on the first surface 5a, and the male Ma of the surface fastener may be provided on the second surface 5b.

  Note that the opening A of the protection member 1 that accommodates the cushion body in the factory needs to be closed by the hook-and-loop fasteners Ma and Mb in order to prevent the cushion body from coming out of the protection member 1 during transportation. However, after being transported to the construction site, the opening A is opened again by the operator in order to perform operations such as attaching to a construction machine (not shown). Therefore, if the opening A is completely closed during transportation, it is troublesome to open the opening A again. Therefore, it is desirable to provide means for temporarily fixing the opening A during transportation. Therefore, in the present embodiment, as shown in FIG. 1, the hooking force of the hook-and-loop fastener Ma is reduced by partially covering the hook-and-loop fastener Ma with the hook-and-loop fastener protection member 21.

  Since the portion provided with the hook-and-loop fastener protection member 21 of the hook-and-loop fastener Ma is not locked with the hook-and-loop fastener Mb (Ma), when the operator puts the hand into the place where the hook-and-loop fastener protection member 21 is provided, A certain opening A can be easily opened. In addition, in this embodiment, although the protection member 21 was attached to Ma, you may attach to hook-and-loop fastener Mb.

  As the surface fastener protecting member 21, for example, a member having an adhesive force such as an adhesive tape is used, but a cross-section with less unevenness is used so that the surface fastener Ma (Mb) is hardly locked with the uneven portion. It is preferable to use the member which has. That is, the hook-and-loop fastener protection member 21 is not engaged with the concavo-convex portion formed on the hook-and-loop fastener Ma (Mb), but is bonded to the hook-and-loop fastener Ma (Mb) by the adhesiveness previously given to the hook-and-loop fastener protection member 21. Has been.

  FIG. 3B is a cross-sectional view of the locking portion 11. As understood from the figure, the male and female hook-and-loop fasteners Ma and Mb are fixed by sewing or the like on the mutually opposing surfaces of the first surface 5a and the second surface 5b folded inward.

  Referring to FIGS. 1 and 2, a ladder belt 12 is provided as another locking means (second locking means) for closing the longitudinal direction of the opening A. The ladder belt 12 is a ladder-shaped locking means having flexibility, and has a plurality of through portions 12a. The locking string 27 is alternately inserted into the through portion 12a of the first surface 5a and the through portion 12a of the ladder belt 12 of the second surface 5b provided at a position facing the ladder belt 12 of the first surface 5a. As a result, the longitudinal direction of the opening A is closed.

Further, as shown in FIG. 2, a single surface fastener Ma, Mb (third locking means 19) is provided at a distance L <b> 1 from the lower end (blocking portion) of the protection member 1.

As shown in FIG. 2, the length L1 in the longitudinal direction on the closing portion side is set equal to the length L2 from the opening A of the protective member 1 to the lower end of the extending portion 10a (10b). For this reason, when connecting a plurality of protection members 1 as shown in FIG. 4, the hook-and-loop fasteners Ma and Mb constituting the third locking means 19 of one (left side in FIG. 4) of the protection member 1 and the other ( The hook-and-loop fastener Mb (Ma) of the locking portion 11 provided on the protective member 1 on the right side in FIG. That is, the hook-and-loop fasteners Ma and Mb constituting the third locking means 19 are used when connecting a plurality of cushion bodies. In FIG. 4, reference symbol C indicates a cushion body.

  When moving from the factory to the construction site and when only one cushion body is used, a single surface fastener protection member 20 (see FIG. 1) is provided on the surface fasteners Ma and Mb constituting the third locking means 19. By adhering, it is possible to prevent the locking function of the hook-and-loop fasteners Ma and Mb from being lowered unexpectedly during transportation. The hook-and-loop fastener protection member 20 only needs to be made of the same material as the hook-and-loop fastener protection member 21 described above.

  Referring to FIGS. 1 and 2, a single insertion hole 13 that penetrates from one side to the other side in the lateral direction is formed at the lower end of the protective member 1 on the closed side. As shown in FIG. 4, when the cushion body C is accommodated in the protective member 1, the folded portion is inserted into the insertion hole in a state where a part of the flexible cushion body C is folded. 13 is inserted from the opening A side of the protective member 1 to the closed portion side so as to be positioned at 13. The non-metallic guide tube 26 having substantially the same length as the insertion hole 13 is inserted into the folded portion. Next, the hook rod 25 is inserted into the guide tube 26.

  When the cushion body C accommodated in the protection member 1 in this state is embedded in the fluidized ground, the construction machine (not shown) grips the hook rod 25, and the cushion body C and the protection member 1 are secured to the ground. Press into. At this time, although there are many foreign substances such as muddy water in the fluidized ground, gravel or stones may come into contact with the cushion body C by the first, second, and third locking means. Is prevented.

  As shown in FIG. 2, the insertion hole 13 is more preferably formed by notches 14 at both corners of the closed portion of the main body. Thus, since the both ends of the closing part are cut obliquely, the guide tube 26 can be easily inserted.

  FIG. 5 is a partially enlarged view showing another embodiment of the protective member according to the present invention.

  The protection member 1A shown in FIG. 5 differs from the protection member 1 shown in FIGS. 1 and 2 in that an anti-separation means (fourth locking means) is provided in the locking portion (first locking means) 11. is there.

  In general, a hook-and-loop fastener has a higher tensile shear strength than peel strength. In particular, when a peeling force is applied from both ends of the hook-and-loop fastener, it is designed so that it can be easily peeled off. Therefore, a means for preventing the surface fastener from inadvertently peeling off during the movement to the construction site and after the construction is required.

  The peeling preventing means shown in FIG. 5 includes through holes 15 and 15 provided at positions that coincide with each other when the locking portions 11 are overlapped with each other, and a locking string S having a diameter that can be inserted into the through holes 15. It consists of.

  With the cushion body C, which is a member to be protected, inserted into the protective member 1A, the hook-and-loop fasteners Ma and Mb provided on the locking portion 11 are locked, and in this state, the center is arranged at a position where the centers are attached. After the locking string S is inserted into the pair of through holes 15, 15, both ends of the locking string S are tied together. By such peeling prevention means, it is possible to reduce the chance of peeling of the hook-and-loop fasteners Ma and Mb under the locked state.

  Note that the through hole 15 may be configured with an eyelet or the like in order to ensure strength, or is configured with a button provided on one side of the locking portion 11 and a hole for inserting the button. Also good. In this case, the locking string S is not necessary. In other words, the hook-and-loop fasteners Ma and Mb that are the first locking means have the first surface 5a and the second surface in a state where the first surface 5a and the second surface 5b constituting the locking portion 11 are locked. Since it prevents that 5b moves mutually in a sliding direction, as a peeling prevention means (4th latching means), the direction where the 1st surface 5a and the 2nd surface 5b which comprise the latching | locking part 11 mutually space | interval Any means may be used as long as it is a means having a high locking force against.

  The present invention is not limited to the above embodiment, and instead of a hook-and-loop fastener or a ladder belt, a through hole such as an eyelet and a locking string inserted through the through hole may be used. A slide fastener or the like may be used.

  As the reinforcing fabric for forming the protective members 1 and 1A in the present invention, it is preferable to use a woven fabric formed from fibers such as polyester and polypropylene, but a non-woven fabric is used according to the strength and intended use. May be. Further, the cushion body C, which is a member to be protected, is filled with a gas inside a tube formed of a thin metal film having flexibility. Therefore, from the viewpoint of preventing the cushion body C from thermally expanding (shrinking) as much as possible and maintaining the vibration isolation performance, it is more preferable to use a white reinforcing cloth that hardly absorbs light.

  From the viewpoint of strength, in principle, the protective member can be formed of plastic, metal, or the like, but when the protected member is a cushion member for vibration isolation composed of metal foil or the like. In consideration of various factors such as the viewpoint of preventing breakage of the cushion body due to contact between metals and the secular change of the protective member after being buried in the original ground, the protective member is More preferably, it is composed of a reinforcing cloth as described above.

  Furthermore, the present invention does not need to be sewn into a bag shape, and at least opens a space for reinforcing member that can form a space capable of accommodating a protected member (cushion body) inside, and a space formed by the reinforcing member. If it comprises a closing means that closes by any means, it falls within the scope of the present invention.

  The cushion body for constructing the vibration isolation wall can be appropriately protected during transportation from the factory, during construction, and after construction.
