Description

  In the present invention, in order to prevent the light-weight studs erected at predetermined intervals, the anti-vibration material penetrating the light-weight studs is sandwiched between the wall materials arranged on both outer sides of the light-weight studs. The present invention relates to a reinforcing member for reinforcing the anti-vibration material in a lightweight partition wall installed horizontally in a space.

As shown in FIG. 3 and FIG. 6 which are drawings according to the present invention, the lightweight partition wall D has lightweight studs C standing between the floor slab 81 and the ceiling slab 82 with a predetermined interval in the horizontal direction. Wall materials 83a and 83b are respectively arranged on both outer sides of each lightweight stud C, and each lightweight stud C is penetrated through the lightweight stud C at a plurality of different positions along the height direction. each wall member 83a, a stop configurations deflection of a plurality of vibration stopper material S is horizontally bridged to the wall in the space V ₁ of the between 83 b. The anti-vibration material S is U-shaped in cross section, and is arranged with its opening facing downward. Both the lightweight stud C and the anti-rest material S are made of lightweight steel.

In lightweight partition walls D, it may be electrical wiring is performed using the wall space V ₁ of the inside. For example, the box B may be arranged inside the lightweight partition wall D on the back side in order to install the electric pipe P along the vertical direction in the wall space V ₁ or to install the outlet on the wall surface. is there. However, in the wall space V ₁ of the lightweight partition wall D, the bracing material S is disposed horizontally in the center in the width direction, so the conduit P or the box B interferes with the bracing material S. As it is, it is not possible to dispose an arrangement body such as the anti-rest material S or the box B. For this reason, if only the arrangement position of the arrangement body in the anti-skid material S is partially omitted and widened, the arrangement becomes possible, but the strength of the lack part of the anti-vibration material S is greatly reduced. Since the original function as the anti-rest material S cannot be achieved, it is not desirable.

Therefore, in Patent Document 1, the upper and lower sides are connected via a flexible pipe connector that can be inserted into the narrow space V ₂ (see FIG. 3) between the anti-vibration material S and one wall member 83a (83b). Each conduit P is connected, and the conduit P can be piped in the wall space V ₁ of the lightweight partition wall D without losing the anti-sway material S. For this reason, the technique according to Patent Document 1 has gained a high technical evaluation over a long period of time in the industry and continues to be implemented at the time of this application.

However, Patent Document 1 has an advantage that the conduit P can be piped inside the lightweight partition wall D without losing the anti-rest material S at all, but in the narrow space V ₂ on the side of the anti-rest material S, Since the electric wire is bent suddenly, the electric wire may be damaged.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

First, the reinforcing member R _{1 according} to the present invention will be described with reference to FIGS. 1 to 6, and thereafter, the end portions of the two anti-vibration members S that are spaced apart are attached to the reinforcing member R ₁ . A method of connecting through the network will be described. The arrangement part in which the plurality of conduits P in the inner space V ₁ of the lightweight partition wall D are arranged in the vertical direction is known in advance, and the arrangement part is in a state where the anti-rest material S is arranged as it is. This is the part where the anti-sway material S and the conduit P interfere. The arrangement portion is substantially synonymous with the arrangement space V ₃ of the arrangement body described later. Therefore, the end portions of the two anti-rest materials S are arranged opposite to each other on both sides of the arrangement portion so that the anti-rest material S does not exist only in the arrangement portion. Two anti-vibration materials S whose end portions are opposed to each other are connected via a reinforcing member R _{1 according} to the present invention. The reinforcing member R ₁ is made of a steel plate, has a U-shaped cross section, and has a configuration in which flange-shaped reinforcing plate portions 2 are bent on the same side at both ends in the width direction of the main body plate portion 1. The length L ₁ is longer than the length L ₂ of the arrangement portion of the conduit P, which is the distance between the opposing end surfaces of the two anti-vibration materials S, by the amount of fixing margin at both ends. Yes.

  The anti-sway material S is made of lightweight steel and has a U-shaped cross section, as shown in FIGS. 1 and 5, at both ends in the width direction of the main body plate 71 arranged horizontally. Each of the reinforcing side plate portions 72 has a shape bent at a right angle downward, and the opening is disposed in a posture facing downward.

Both end portions in the longitudinal direction of the main body plate portion 1 of the reinforcing member R ₁ are fixed portions 11 that are connected and fixed to opposite end portions of the two anti-vibration materials S described above via bracket-shaped fixing brackets F. The portion of the reinforcing member R ₁ excluding the fixing portions 11 at both ends is a non-existing portion K _{1 of the} single brace material S (each end portion of the two brace members S is opposed to be spaced apart). In this state, a reinforcing portion 12 is provided for connecting and reinforcing the space portion (see FIG. 1) in which the anti-rest material S does not exist. The fixture F is made of steel. The central portion in the width direction of the portion corresponding to the reinforcing portion 12 of the main body plate portion 1 is partially bent in a state where the reinforcing plate portion 2 is depressed toward the side where the reinforcing plate portion 2 protrudes so that the cross section becomes a V shape. The V-shaped recess 3 is formed along the longitudinal direction. The bent portion in which the V-shaped concave portion 3 is formed functions as a kind of rib to reinforce the main body plate portion 1. In FIG. 4A, reference numeral 7 denotes a connecting portion that divides the slit-shaped first screw pilot hole 4 continuous in the longitudinal direction. A plurality of slit-shaped first screw pilot holes 4 are formed at the bottom of the V-shaped recess 3 in a discontinuous state along the longitudinal direction. The reason why the plurality of slit-like first screw pilot holes 4 are discontinuous is to prevent a decrease in strength due to being continuous. The reinforcing plate portion 2 is provided with a plurality of pairs of second screw lower holes 5 in a one-to-one pair with the V-shaped concave portion 3 interposed therebetween at regular intervals in the longitudinal direction. Each of the first and second screw under holes 4 and 5, the front surface of the main plate portion 1 of the reinforcing member R _1, is used conduit P, and distribution設体such box B when screw fixing. Further, in order to fix the fixing bracket F with screws to each fixing portion 11 at both ends in the longitudinal direction of the reinforcing portion 12, a set of two at a predetermined interval along the width direction of the reinforcing portion 12. The formed third screw pilot holes 6 are respectively formed. The reinforcing member R ₁ is disposed so that the main body plate portion 1 is vertical and the opening faces the other wall member 83 b so that the reinforcing member R ₁ can be disposed in the narrow space V ₂ .

  The fixing bracket F includes a main body portion 21 having a U-shaped cross-section that can accommodate the anti-vibration material S arranged with its opening facing downward, and an opening-side end of each counter plate portion 21a of the main body portion 21. It comprises a pair of fixed plate portions 22 formed by bending the portion outward. Screw insertion holes 23 and 24 are formed in the top plate portion 21b of the main body portion 21 and the pair of fixed plate portions 22, respectively.

Then, as shown in FIGS. 2 and 3, a reinforcing member R ₁ is disposed on the other outer surface Sb side of the non-existing portion K ₁ between the two bracing members S, and the reinforcing member The fixing portions 11 at both ends in the longitudinal direction of R ₁ are connected and fixed to the end portions of the anti-rest materials S via the fixing metal F. Sa represents one outer surface of the anti-rest material S. Accordingly, the reinforcing member R ₁ is disposed so as to recede by the width Ws of the anti-rest material S with respect to the one outer side surface Sa of the anti-static material S. As a result, the reinforcing member R ₁ and the wall material 83 a In between, the width (W ₃ ) is widened by the width Ws of the anti-rest material S with respect to the width (W ₂ ) of the narrow space V ₂ between the anti-static material S and the one wall member 83a. A wide arrangement space V ₃ is formed. The screw J inserted into the screw insertion hole 24 of each fixing plate portion 22 of the fixing bracket F is screwed into the third screw lower hole 6 of the fixing portion 11 of the reinforcing member R ₁ , and each ceiling of the fixing bracket F is fixed. The screw J inserted through the screw insertion hole 23 of the plate portion 21b is screwed to the outer side surface Sa of the anti-rest material S.

And as shown in Drawing 2, Drawing 3, and Drawing 6, the same position along the horizontal direction of each of a plurality of anti-skid materials S arranged in a different position along the height direction of lightweight partition wall D Each portion has a non-existing portion K ₁ , and each non-existing portion K ₁ is reinforced by the reinforcing member R ₁ as described above, and is wide between one wall member 83a. An arrangement space V ₃ having a width (W ₃ ) is formed. When piping a plurality of conduits P along the vertical direction in the wall space V ₁ of the lightweight partition wall D, a plurality of the pipes P are disposed in the arrangement space V ₃ at a portion intersecting with each anti-sway material S. The electric pipe P is disposed while maintaining a straight shape. Each conduit P is fixed to the reinforcing member R ₁ via saddles 41 and 42 as necessary. That is, the saddle 41 is fixed through a screw J screwed into the first screw lower hole 4 of the main body plate portion 1 of the reinforcing member R ₁ at the connecting plate portion 41a at the center in the width direction. It is fixed to the main body plate portion 1 (reinforcing member R ₁ ) [see FIG. 4B]. Saddle 41, to fix the two conduit P the reinforcing member R _1. On the other hand, the saddle 42 is fixed to the main body plate portion 1 of the reinforcing member R ₁ via the connecting plate portion 42a at one end in the width direction, and fixes one conduit P to the reinforcing member R ₁ .

As described above, since the three conduits P can be fixed to the reinforcing member R ₁ via the saddles 41 and 42 at the portion intersecting with the anti-stress material S, the wiring state of the conduit P is stabilized. The fixing of the conduit P to the reinforcing member R ₁ is not limited to the saddles 41 and 42. As shown in FIG. 7, a binding band 45 that is bent by plastic deformation is wound around the conduit P, and both ends thereof are wound. In the crossed state, the portions are inserted into the adjacent first screw pilot holes 4 formed in the main body plate portion 1 of the reinforcing member R ₁ , and the bundling in the crossed state is performed on the back side of the main body plate portion 1. The both ends of the band 45 may be tied to the connecting portions 7 that divide the first screw pilot holes 4 adjacent to each other.

As shown in FIG. 3, the ends of the two anti-vibration materials S are separated from each other, and a non-existing portion K ₁ of the anti-vibration material S is formed between the ends, and the reinforcing member R ₁ is In each of the non-existing portions K ₁ , each end of the two anti-rest members S in a state of being largely retracted toward the other outer surface S b with respect to the one outer surface Sa of the anti-rest member S _1. The parts are reinforced and connected via the reinforcing member R _1, and as a result, the anti-rest material is provided between the _one wall member 83 a and the reinforcing member R ₁ with respect to the width (W ₂ ) of the narrow space V _2. A disposition space V _{3 that} is widened by the width of S (Ws) is formed. For this reason, the electric conduit P is provided with sufficient margin and is maintained in a straight shape in the arrangement space V ₃ . As a result, since the electric wire accommodated in the conduit P can be maintained straight without being bent or greatly bent, the electric wire is not damaged.

Therefore, in the wide arrangement space V ₃ , another arrangement body having a large depth length other than the conduit P that effectively uses the width (W ₃ ) can be arranged. A typical example of such an arrangement is a box B arranged in the wall on the back side of the wall outlet, and is formed on the bottom wall 51 of the box B as shown in FIGS. By inserting the screw J through the pair of screw insertion holes 52 and screwing the screw J into the first screw lower hole 4 formed in the main body plate portion 1 of the reinforcing member R ₁ , the arrangement space V _The box B can be arranged in ₃ and the box B can be fixed to the reinforcing member R ₁ on the back side.

The reinforcing member R _{2 of the} second embodiment shown in FIGS. 10 and 11 has a reinforcing portion 12 ′ that protrudes from the fixing portion 11 ′ at both ends in the longitudinal direction in the reinforcing member R ₁ . The height of 12 ′ is higher than the height of the fixing portion 11 ′, and the portion of the reinforcing portion 12 ′ that is higher than the fixing portion 11 ′ is arranged opposite to each other with the end surfaces separated from each other. the insertion portion 13 to be inserted into the vibration stopper member missing portion K ₁ of S formed between the two vibration stopper member S that is. With this configuration, the end surfaces at both ends in the longitudinal direction of the reinforcing portion 12 ′ are contact surfaces on which the opposite end surfaces of the two anti-vibration materials S with the end portions facing each other at a predetermined interval can contact each other. 14

For this reason, when the lightweight partition wall D is assembled, one abutment surface 14 of the insertion portion 13 of the reinforcing member R ₂ is placed on one end surface of the two anti-vibration members S whose end surfaces are opposed to each other with a predetermined interval. In a state where the reinforcement member R ₂ is cantilevered and fixed to the end portion of the one bracing material S by the fixing bracket F, and then cantilevered to the one bracing material S. the other abutment face 14 of the reinforcing member R ₂ of the insertion portion 13 becomes Jo and are connected by abutting the end face of the other vibration stopper member S, by a separate fixing bracket F, the reinforcing member R ₂ When the other abutment surface 14 and the other anti-sway material S are connected, the two anti-sway materials S are connected via the reinforcing member S. Therefore, the work of connecting the two vibration stopper member S by the reinforcing member R ₂ in the assembly of lightweight partition wall D is facilitated. Further, as the height of the reinforcing portion 12 ′ is increased, the section modulus of the reinforcing portion 12 ′ is increased, and as a result, the strength of connecting the two anti-vibration materials S is increased.

In a state where the _two anti-vibration members S whose end surfaces are opposed to each other with a predetermined interval are connected and reinforced by the reinforcing member R ₂ , as shown in FIG. 11, the fixed portion 11 ′ in the reinforcing portion 12 ′ portion 12a which projects against 'in order to enter the missing portion K ₁ of the stop member S vibration corresponding formed by sealing material S oscillation of two, reinforcing portion 12 relative to the outer surface Sa of Futome material S' the amount of retraction is smaller than the amount of recession of the reinforcing member R _1. As a result, 'the width W _3' of disposing space V ₃ is the becomes narrower than the width W ₃ of the disposing space V _3, when compared to the width W ₂ of the narrow space V _2, it is sufficiently widened distribution An installation space V ₃ ′ is formed.

In Examples 1 and 2, since the wiring position of the conduit P is known in advance, each of the two restraining materials S can be placed at the wiring position of the conduit P without missing or missing the restraining material S. by spaced ends to form a missing portion K ₁ of Futome material S, in the portion of the missing portion K _1, is retracted positioned against one of the outer side surface Sa of Futome material S A wide arrangement space V ₃ (V ₃ ′) is formed by connecting and reinforcing the two anti-vibration members S via the reinforcing member R ₁ (R ₂ ).

On the other hand, as shown in FIG. 12, in Example 3, at the wiring position of the conduit P, the one outer surface Sa side of the brace S is missing in a rectangular shape in plan view, and the missing portion By forming K ₂ , an arrangement space V ₃ ″ having a width W ₃ ″ is formed. As a result, the connection part 61 remains in the anti-vibration material S, and the anti-vibration material S has a continuous single shape by the connection part 61. However, since the portion of the connecting portion 61 in the anti-vibration material S is largely omitted, the strength is reduced as compared with other general portions.

Therefore, similarly to the first embodiment, the reinforcing member R ₁ is disposed on the back side of the connecting portion 61 of the anti-vibration material S to reinforce the connecting portion 61 whose strength has been reduced. For this reason, the width of the arrangement space V ₃ ″ is formed by the inner surface of one wall member 83a and the inner end surface 61a of the connecting portion 61 of the anti-vibration material S, and one outer surface of the anti-vibration material S. position of the inner end surface 61a for Sa has a retracted position contributes retracted portion to increase the width with respect to the narrow space V _2. The retraction amount of the inner end surface 61a of the connecting portion 61 of the third embodiment is smaller than the retraction amount of the reinforcing member R1 of the _first embodiment (equal to the width Ws of the anti-rest material S). However, with the conduit P, the piping can be widened and maintained straight in the arrangement space V ₃ ″.

Accordingly, since the first and second screw pilot holes 4 and 5 of the reinforcing member R ₁ used in the third embodiment are not used, in the second embodiment, the first and second screw holes are formed in the main body plate portion 1. It is possible to use a reinforcing member in which the screw holes 4 and 5 are not formed.

Further, fixing of the fixing portions 11 at both ends of the reinforcing members R ₁ and R _{2 to} the anti-rest material S is performed in a state where the entire anti-vibration material S is accommodated in the main body portion 21 of the fixing bracket F in a cross-sectional view. Since the fixing bracket F is used, there is an advantage that the fixing strength between the anti-rest material S and the reinforcing members R ₁ and R ₂ is increased.
