Description

  The present invention relates to a pipe-holding band fixture for fixing a pipe-holding band for attaching a pipe arranged in a vertical direction or the like along the surface of a building structure such as an outer wall.

  As shown in FIGS. 4A to 4C, the conventional pipe holding band attachment 110 includes a base plate portion 111 attached to the surface of a building structure such as the outer wall 3, and a pipe fixing pipe. A rectangular plate-shaped attachment portion 112 for attaching a holding band (not shown in this figure; see FIG. 3) and a fixing portion 113 constituted by a shaft-like screw body fixed to the outer wall 3 are connected. Configured. The substrate portion 111 has a concave portion 111a at substantially the center, the fixing portion 113 is formed to protrude from the bottom of the concave portion 111a, and the mounting portion 112 is formed to protrude to the outer surface side of the concave portion 111a.

  In order to connect the three members as described above, two separate through holes 111b as shown in FIG. 4 (a) are formed in the central portion of the recess 111a (see FIG. 4 (c)) of the substrate portion 111. Is formed. On the other hand, the base end portion of the mounting portion 112 (the end portion to be connected and fixed to the substrate portion 111 and the fixing portion 113) is fixed in a concave shape that is inserted into the insertion hole 111b of the substrate portion 111 and is bifurcated. A piece 112a is formed.

  As shown in FIG. 4C, the fixed piece portion 112a is inserted into the insertion hole 111b of the substrate portion 111, and the base end of the fixed portion 113 is interposed between the fixed piece portions 112a protruding from the insertion hole 111b toward the concave portion 111a.

  However, in the conventional connection structure, the head portion 113a of the fixing portion 113 may not be firmly fitted between the fixing piece portions 112a due to a molding error of the fixing piece portion 112a of the attachment portion 112 and is welded. However, there is a possibility that the joining of both members becomes weak. In addition, displacement between both members is likely to occur.

  Moreover, since the fixing piece 112a of the attachment portion 112 has a leg-like bifurcated shape, depending on the width dimension of the attachment portion 112, each fixing piece portion 112a may become thin, and the strength of the base portion of the fixing piece portion 112a may be reduced. Yes, there is a risk of breakage.

  In particular, the welding for connecting the three members is performed only on the concave portion 111a side of the substrate portion 111 and not on the front surface side in consideration of aesthetics, and therefore, the concave bottom between the fixed piece portions 112a of the mounting portion 112 (the substrate portion) In some cases, a slight gap may be formed between the plate portion 111 and the plate surface of the substrate portion 111. In such a thing, after attaching to a building structure, rain water permeates into the gap, and the infiltrated water flows into the insertion holes 111b on both sides. Therefore, there is a possibility that the deterioration of the base portion of the fixed piece portion 112a may be accelerated.

  The present invention has been proposed in view of such circumstances, and the object of the present invention is to provide a pipe-holding band attachment that is difficult to separate and that has excellent strength. It is to provide.

The substrate portion has an insertion hole through which the fixed piece portion is inserted into the concave portion, and the fixed portion has an engagement groove with which the distal end of the fixed piece portion engages at the base end portion. Thus, the fixed piece portion has a gap between the abutting portion and the plate surface of the substrate portion, so that even if rainwater enters, it is easy to flow outward. Contact portion is disposed on both sides in the width direction protrudes in a convex-shape, and the width dimension of the fixing piece portion is larger than the width dimension of the contact portion, Mounting portion and a fixed portion Both the base end portions are welded and fixed in the concave portion in a state where the fixing piece portion and the engaging groove are engaged.

  According to the pipe holding band mounting tool of the first aspect, since the structure is such that the fixing piece portion of the mounting portion and the engaging groove of the fixing portion are engaged, both connected members can obtain a sense of unity. The difference between the two is less likely to occur. Further, since the attachment portion and the fixing portion are firmly coupled, the possibility that the three members including the substrate portion are separated is low.

Further , according to the pipe holding band mounting tool of the first aspect, since the fixed piece portion projects with the contact portions on both sides, the contact portions on both sides contact the plate surface of the substrate portion. , The sense of unity between the mounting portion and the substrate portion is improved. Further, since the fixed piece portion is not bifurcated and is arranged in a convex shape at the center in the width direction of the mounting portion, the width dimension can be increased, and the strength of the base portion of the fixed piece portion can be improved. Furthermore, since the contact part is formed at both ends in the width direction of the mounting part, a gap is formed between the contact part and the plate surface of the board part, and even if rainwater enters the gap, it will be outward. Since it is easy to flow, much rain water does not concentrate near the base of the fixed piece compared to the contact part formed in the center, and the deterioration of the base of the fixed piece can be delayed. it can.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. First, the basic configuration of the pipe holding band fixture 10 will be described.

  The pipe holding band attachment 10 (hereinafter referred to as attachment 10) includes a substrate portion 11 in which a recessed portion 11a provided substantially at the center is attached to a surface of a building structure, and a recessed portion of the substrate portion 11. The shaft-shaped fixing part 13 that protrudes from the plate surface on the 11a side and is fixed to the building structure, and the pipe holding band 30 that protrudes in the direction opposite to the fixing part 13 from the plate surface of the substrate part 11 are attached. And a plate-like mounting portion 12 for the purpose.

  The attachment portion 12 has a shape having a contact portion 12b in contact with the plate surface of the substrate portion 11 and a fixed piece portion 12a protruding from the contact portion 12b at the base end portion. The substrate part 11 has an insertion hole 11b through which the fixed piece part 12a is inserted into the recess 11a. The fixed portion 13 has an engagement groove 13c at the base end portion thereof with which the distal end of the fixed piece portion 12a is engaged. Both base end portions of the attachment portion 12 and the fixing portion 13 are welded and fixed in the concave portion 11a in a state where the fixing piece portion 12a and the engaging groove 13c are engaged.

Next, the fixture 10 shown in FIGS. 1 and 2 will be described in detail.
The fixture 10 is formed by integrating all of the three members of the substrate portion 11, the fixing portion, and the attachment portion that are made of metal such as stainless steel, and the members are integrated by welding or the like. Hereinafter, the three members will be described in order, and further their connection structure will be described. In the following description, on the assumption that the fixture 10 is attached to the outer wall 3, the attachment portion 12 side is referred to as the front, and the fixing portion 13 side is referred to as the rear.

  As shown in FIG. 3, the attachment portion 12 disposed forward when attached to the outer wall 3 is a portion for attaching the pipe holding band 30, and the attachment piece portion 31 of the pipe holding band 30 is a plate. It fixes so that the attachment part 12 of a shape may be clamped. The attachment portion 12 is provided with a long hole 12c for fixing the pair of attachment piece portions 31 with bolts 33 and nuts 34 through two insertion holes 31a.

  The pipe holding band 30 includes an annular band portion 32 in which the attachment piece portion 31 is extended, and the band portion 32 can hold a pipe 35 such as a bag.

  In the fixture 10, the substrate portion 11 disposed behind the attachment portion 12 has a shape in which a central portion in the width direction protrudes in a convex shape. Further, the projecting height dimension of the projecting portion is larger than the plate thickness dimension of the bottom of the concave portion 11a of the substrate portion 11, and projects to the concave portion 11a side (behind the bottom surface of the concave portion 11a). This projecting portion is the above-described fixed piece portion 12a, and the end portions on both sides in the width direction are the above-described contact portions 12b.

  The substrate part 11 arranged behind the attachment part 12 is a part attached to the surface of the outer wall 3 when the fixture 10 is attached to the outer wall 3, and on the back side of the convex part at the center of the plane, A recess 11a is formed as a part for connecting the front mounting portion 12 and the rear fixing portion 13 together. In other words, the substrate portion 11 has a pan shape when viewed from the rear, and is formed so that the annular portion 11 c on the outer periphery of the substrate portion 11 contacts the outer wall 3 when the fixture 10 is attached to the outer wall 3. Has been.

  A rectangular insertion hole 11b penetrating in the front-rear direction is formed at the bottom of the concave portion 11a of the substrate portion 11. As described above, the insertion hole 11b is a hole through which the fixed piece portion 12a of the mounting portion 12 is inserted, and has a size and shape that matches the cross-sectional shape of the fixed piece portion 12a so that the fixed piece portion 12a can be inserted. It is a hole.

  The fixing portion 13 disposed behind the substrate portion 11 is a screw body (bolt body) having a hexagonal head portion 13a and a screw portion 13b, and the head portion 13a has the mounting portion 12 described above. An engagement groove 13c for engaging with the fixed piece 12a is formed.

  As shown in FIGS. 1A and 1B and FIGS. 2A and 2B, the fixing piece portion 12a of the mounting portion 12 is inserted into the insertion hole 11b of the substrate portion 11 and protrudes rearward from the recess portion 11a. In a state where the tip of the fixed piece 12a and the engaging groove 13c of the fixed portion 13 are engaged in the concave portion 11a, the connecting portion including the bottom surface of the concave portion 11a is welded and fixed. Although not shown, it is desirable that the front end surface of the head portion 13a of the fixing portion 13 is in contact with the bottom surface of the concave portion 11a.

  In the state where the above three members are connected as the fixture 10, the contact portion 12 b of the mounting portion 12 is in contact with the plate surface of the substrate portion 11. Note that a slight gap may be formed between the contact portion 12 b and the plate surface of the substrate portion 11.

  As described above, the attachment portion 12 and the fixing portion 13 are connected by the fixing piece portion 12a penetrating the base plate portion 11 and the fixing piece portion 12a penetrating the engaging groove 13c being welded and fixed. Since it has a structure, both connected members can have a sense of unity, and deviation between the two members hardly occurs. Moreover, since the attachment part 12 and the fixing | fixed part 13 couple | bond together firmly in the bottom face of the recessed part 11a of the board | substrate part 11, there is almost no possibility that these three members will isolate | separate.

  Further, the fixed piece portion 12a of the attachment portion 12 is formed in a convex shape with the contact portions 12b arranged on both sides in the width direction. The portion 12 b is in contact with or close to the front plate surface of the substrate portion 11. Therefore, the sense of unity between the attachment portion 12 and the substrate portion 11 is improved. Furthermore, since the fixed piece portion 12a is not bifurcated and is arranged in a convex shape at the center in the width direction of the mounting portion 12, the width dimension can be increased, and the strength of the base portion 12aa of the fixed piece portion 12a is improved. Can be made. Therefore, the possibility that the fixed piece 12a is bent or broken is low.

  Particularly in the example of this figure, since the width dimension (W1) of the fixed piece portion 12a is larger than the width dimension (W2 × 2) of the both contact portions 12b, the strength of the base portion 12aa of the fixed piece portion 12a is increased. This can be further increased (see FIG. 2A). For this reason, damage such as bending at the base portion 12aa of the fixed piece portion 12a is unlikely to occur.

  In addition, since the abutment portion 12b is formed at both ends in the width direction of the attachment portion 12 in the fixture 10 of this example, there is a gap between the abutment portion 12b and the plate surface of the substrate portion 11, and rainwater is generated. Even if it enters, it will be easier to flow outward. Therefore, there is no fear that the amount of moisture reaching the periphery of the base 12aa of the fixed piece 12a (near the insertion hole 11b) increases compared to the contact 12b formed in the center. Deterioration due to moisture can be delayed. In particular, if the width dimension (W2) of the contact portion 12b is reduced, the amount of moisture entering the gap between the contact portion 12b and the plate surface of the substrate portion 11 is naturally reduced. Degradation can be further delayed.

  Note that the shape of the fixed piece portion 12a of the attachment portion 12 is not limited to that of the present embodiment, and various shapes are allowed. The fixed piece portion 12a and the contact portion 12b may have a stepped shape or a concave shape (the fixed piece portion 12a has a bifurcated shape). The fixed piece portion 12a may protrude from any portion, and any structure that engages with the engaging groove 13c of the fixed portion 13 may be used.
