JP-A-9-78787

  Conventional anchor parts are formed by joining two members, a plate material and a deformed reinforcing bar, by welding. Therefore, it is necessary to prepare two types of members for the manufacture thereof. Therefore, it has been necessary to perform the management of the members, the coupling work, and the like.

  An object of the present invention is to provide an anchor part for a handrail strut that can be formed by a single member and a method for manufacturing the anchor part.

  The anchor part of the handrail support according to the present invention includes a reinforcing part for reinforcing the support by being coupled to the handrail support, and a casing in which the handrail is installed extending downward from the reinforcing part. In the anchor part of the handrail support having an anchor portion embedded in the inside of the rail, the reinforcing portion and the anchor portion are integrally formed in one member. .

  In the present invention, since the reinforcing portion and the anchor portion are integrally formed in one member, the anchor part can be formed by one member unlike the conventional case. For this reason, it is not necessary to prepare a plurality of members, and it is not necessary to manage these members, to perform a coupling operation, and the like, so that complicated operations can be omitted.

  In the anchor part of the handrail strut according to the present invention, the reinforcing portion for reinforcing the strut may be inserted into the strut and coupled to the strut, not inserted into the strut, in other words. , It may be coupled to this strut, such as applied to the outer surface of the strut. Further, a part of the reinforcing portion may be inserted into the support column and the other portion may be exposed to the outside of the support column. Further, the reinforcing portion may extend linearly or be bent. Further, the reinforcing portion may be bendable, in other words, may have an angle adjusting function.

  Further, the reinforcing portion has an angle adjusting function, and for this purpose, the reinforcing portion is composed of an upper portion coupled to the support column and a lower portion coupled to the anchor portion, and a lower portion. When it can be bent with respect to the upper part, only the lower part may be formed integrally with the anchor part.

  Moreover, you may provide the contact part which contacts the upper surface of the above-mentioned housing | casing in which a handrail is installed in the boundary part of a reinforcement part and an anchor part in the anchor component of the handrail support | pillar which concerns on this invention.

  According to this, when inserting the anchor portion into the hole formed in the housing in order to embed the anchor portion inside the housing, the anchor portion is inserted into the hole of the housing until the abutting portion contacts the upper surface of the housing. Thus, an appropriate insertion depth of the anchor portion with respect to the hole can be obtained.

  Thus, the upper surface of the housing with which the contact portion abuts may be a horizontal surface or an inclined surface. An example of a housing whose upper surface is inclined is a staircase housing, and another example is a design wall.

  In addition, the form of the said contact part provided in the boundary part of a reinforcement part and an anchor part is arbitrary. One example is that the abutting portion is the lower surface of the reinforcing portion itself, and another example is that the abutting portion is a protruding piece formed on the lower surface of the reinforcing portion by bending or the like.

  Moreover, you may provide an uneven | corrugated | grooved part in the surface of an anchor part.

  According to this, when the anchor portion is adhesively bonded to the housing by being filled with an adhesive in the above-described hole of the housing, resistance to the anchor portion coming out from the hole of the housing is generated in the uneven portion. Thus, the anchor portion can be coupled to the housing with high strength.

  Thus, also when providing an uneven part on the surface of an anchor part, the form of this uneven part is arbitrary. One example thereof is to form the concavo-convex part by deforming the surface of the anchor part, and another example is to form the concavo-convex part by attaching a concavo-convex member to the anchor part.

  In the case where the concavo-convex portion is formed by deforming the surface of the anchor portion, this deformation processing may be a crushing process, a cutting process, a bending process, a perforating process, A twisting process or the like that forms a helical torsional deformation portion on the surface may also be used.

  Further, when the uneven portion is formed by attaching an uneven member to the anchor portion, the uneven member may be a rod-like member such as a pin, a rivet or a bolt, a block-like member, or an anchor When a male screw is formed on the part, a nut or the like screwed onto the male screw may be used. Furthermore, the means for attaching the uneven member to the anchor portion may be press fitting the uneven member into a hole or the like formed in the anchor portion, or may be connected to the anchor portion by welding or the like. The concave / convex member may be adhered to the portion, and may be screwed as can be seen from the case of the male screw and nut described above.

  Moreover, the said uneven | corrugated | grooved part may be based on one among what forms unevenness | corrugations, such as a depression, a protrusion, a hole, and a groove | channel, and may be based on a some combination.

  In addition, the direction of the anchor portion with respect to the reinforcing portion is also arbitrary. One example is to extend the anchor portion straight on the extension in the length direction of the reinforcing portion, and the other example is to fix the anchor portion to the reinforcing portion. It is to make it extend in the direction which makes an angle with respect to.

  When the anchor portion is extended in a direction that forms an angle with respect to the reinforcing portion, when the anchor portion is inserted into the hole of the housing filled with the adhesive, the anchor portion is inserted with an inclination angle with respect to the vertical direction. Therefore, when the anchor portion is adhesively bonded to the housing with the adhesive, the anchor portion can generate a large resistance against the anchor portion from coming out of the hole of the housing. Can be bonded to the housing with great strength.

  In addition, extending the anchor portion in a direction that forms an angle with respect to the reinforcing portion means, for example, that the upper surface of the housing on which the handrail is installed is inclined, and is perpendicular to the upper surface of the inclined housing. The present invention can also be applied to the case where the anchor portion is inserted into the reinforced portion and the reinforcing portion is in a vertical posture.

  Further, the anchor portion may extend linearly, may have a folded shape, may have an arc shape, or may have a zigzag shape or the like.

  In the present invention, the number of anchor portions may be one or plural.

  When the number of anchor portions is plural, the interval between these anchor portions may be the same from the base end portion of the anchor portion, which is a connection portion with the reinforcing portion, to the tip end portion of the anchor portion, in other words, These anchor portions may be parallel, or the interval between the anchor portions may be increased from the proximal end portion of the anchor portion, which is a connection portion with the reinforcing portion, to the distal end portion of the anchor portion.

  When the interval between the plurality of anchor portions is increased from the proximal end portion of the anchor portion, which is a connection portion with the reinforcing portion, to the distal end portion of the anchor portion, the anchor portion is inserted into the hole of the housing filled with the adhesive. As a result, when these anchor portions are adhesively bonded to the housing with an adhesive, the shape formed by the plurality of anchor portions is divergent, which also prevents the anchor portion from coming out of the hole in the housing. A large resistance force can be generated, and the anchor portion can be coupled to the housing with a large strength.

  Such an effect can also be obtained when the frame is formed of concrete or mortar after the anchor part is installed.

  A method for manufacturing an anchor part for a handrail support according to the present invention includes a reinforcing portion for reinforcing the support by being coupled to the handrail support, and a lower portion extending from the reinforcing portion, wherein the handrail is installed. This is a method for manufacturing an anchor part of a handrail strut that is integrally formed with a single member and an anchor portion embedded in the inside of the housing, and has the same cross-sectional shape as a length. The anchor part material that is continuous in the direction, and the anchor perpendicular to the length direction from one end part in the length direction of the anchor part material to the middle part in the length direction.

The handrail which concerns on this embodiment is a handrail installed in the waist wall of the balconi of buildings, such as an apartment house. FIG. 1 shows a handrail 10 installed on a waist wall 1 which is a building frame. The handrail 10 is disposed between a plurality of columns 11, a top rail 12 spanned between the upper ends of these columns 11, and two columns 11 adjacent to each other. And a handrail panel 13 made of the member 13B. The handrail panel 13 is coupled to these columns 11 via brackets (not shown) attached to opposite sides of the two columns 11 adjacent to each other.

  Each column 11 is erected and fixed to the waist wall 1 by an anchor part 20 according to the present embodiment. This anchor part 20 is shown in FIG. 2 which is a cross-sectional view taken along line S2-S2 of FIG. FIG. 3 is a sectional view taken along line S3-S3, and the entirety of the anchor part 20 is shown in FIG.

  As shown in FIG. 4, the anchor component 20 includes an upper reinforcing portion 21 and a lower anchor portion 22. The reinforcing portion 21 and the anchor portion 22 are integrally formed in one member. That is, the anchor component 20 according to the present embodiment is not formed by joining two members, that is, a reinforcing member and an anchor member, by welding or the like, and is an upper portion of one member having no joint portion. Is the reinforcing portion 21, and the lower portion is the anchor portion 22.

  Thus, in this embodiment, since the anchor component 20 having the reinforcing portion 21 and the anchor portion 22 is formed by one member, a member that becomes the reinforcing portion and a member that becomes the anchor portion are prepared. This eliminates the need to manage these members and to perform a joining operation such as welding, thereby making it possible to omit complicated operations. The accuracy of the positional relationship can be enhanced.

  As shown in FIGS. 2 and 4, the reinforcing part 21 of the anchor part 20 includes a web part 21 </ b> A extending in the width direction of the anchor part 20, and each extending in the depth direction of the anchor part 20. It has a substantially channel shape in cross section consisting of a pair of flange portions 21B facing each other and a hollow portion 21C that is recessed inwardly between the web portion 21A and the flange portion 21B. The substantially channel shape in cross section is continuous in the vertical direction, which is the length direction of the anchor part 20. Further, the length of the reinforcing portion 21 is shorter than the length of the support column 11, but the dimensions of the reinforcing portion 21 in two directions orthogonal to the length direction of the reinforcing portion 21 (the dimension in the width direction and the depth direction of the anchor part 20). 2 is a dimension corresponding to the dimension of the internal space of the column 11 which is an extruded product or a pultruded product made of aluminum alloy, as shown in FIG.

  For this reason, the reinforcing part 21 can be inserted into the hollow internal space of the column 11 and, as shown in FIG. 2, the column 11 and the reinforcing unit are inserted into the hole 11 </ b> A formed in the column 11.

  Thus, the reinforcement part 21 of the anchor part 20 is inserted into the inside of the column 11, and these pillars 11 and the reinforcement part 21 are coupled with the screws 30, whereby the strength of the column 11 is increased. 21 will be reinforced. As described above, the reinforcing portion 21 has a substantially channel shape in cross section that is continuous in the length direction of the reinforcing portion 21, and the substantially channel shape in cross section is orthogonal to the length direction of the reinforcing portion 21. Since the cross-sectional shape is a bent shape, the strength of the reinforcing portion 21 itself can be increased by the bent shape. Therefore, the strength of the column 11 reinforced by the reinforcing portion 21 is also increased. Can be bigger.

  As shown in FIG. 2, screw pocket portions 11 </ b> B that are continuous in the length direction (vertical direction) of the column 11 are provided at the four corners inside the column 11. In the case where the top rail 12 described with reference to FIG. 1 is composed of a lower base member 12A and an upper cover member 12B that is locked to the base member 12A, the portion 11B serves as a support 11 for the base member 12A. This is for screwing a screw for fixing to the upper surface of the screw. Even if such a screw pocket portion 11B is formed inside the column 11, the above-mentioned recess portion 21C is provided in the reinforcing portion 21 inserted into the column 11 at a position corresponding to the position of the screw pocket portion 11B. Therefore, it is possible to prevent the screw pocket portion 11B and the reinforcing portion 21 from interfering with each other due to these hollow portions 21C, and thereby the reinforcing portion 21 can be inserted into the support column 11 as predetermined. ing.

  As shown in FIG. 4, the anchor portion 22 described above extends downward from a part of the lower surface of the reinforcing portion 21, and there are two anchor portions 22 in the width direction of the anchor part 20. The respective anchor portions 22 having a length are parallel to each other and extend downward from the reinforcing portion 21. Further, each anchor portion 22 has a cylindrical shape in which a cross-sectional shape orthogonal to the length direction of the anchor portion 22 is circular. Furthermore, the uneven | corrugated | grooved part 22A is formed in the surface of each anchor part 22, The surface area of the anchor part 22 is large by this uneven | corrugated | grooved part 22A.

  When performing the operation of installing the handrail 10 shown in FIG. 1 on the waist wall 1 of the building, first, the two holes 2 shown in FIG. The gel-like adhesive 3 shown in FIG. 3 is filled in the holes 2 formed at the corresponding intervals and drilled vertically downward, and then the anchor portions 22 are vertically lowered in the holes 2. insert. This insertion operation is performed until the two lower surfaces 21E of the reinforcing portion 21 deviated from the arrangement position of the anchor portion 22 abut on the upper surface 1A of the waist wall 1. That is, in this embodiment, the two lower surfaces 21E of the reinforcing portion 21 that are out of the arrangement position of the anchor portion 22 and are provided at the boundary portion between the reinforcing portion 21 and the anchor portion 22 are the upper surfaces of the waist wall 1. These contact portions allow the anchor portion 22 to be inserted into the hole 2 by a predetermined depth, and from the upper surface 1A of the waist wall 1 to a predetermined height. The reinforcing portion 21 that rises by the amount can be provided.

  As shown in FIGS. 3 and 4, by forming a projecting piece portion 21 </ b> F by bending or the like on the lower surface of the reinforcing portion 21 between the two anchor portions 22, it is possible to remove the anchor portion 22 from the arrangement position. Not only the two lower surfaces 21E of the detachable reinforcing portion 21 but also the projecting piece portions 21F are provided at the boundary between the reinforcing portion 21 and the anchor portion 22 and contact the upper surface 1A of the waist wall 1. It is good also as a contact part.

  As shown in the figure, the number of abutting portions is set such that two lower surfaces 21E of the reinforcing portion 21 deviated from the position where the anchor portion 22 is disposed, and one projecting piece portion 21F provided between these lower surfaces 21E. When the total number of the contact portions is three, these contact portions form a triangle in plan view, and thus the anchor portion 22 inserted into the hole 2 is fixed by fixing the gel-like adhesive 3 described above. Until it is done, the anchor part 20 can be made to stand on the upper surface 1 </ b> A of the waist wall 1.

  Note that the number and shape of the projecting piece portions 21F serving as the contact portions are not limited to those in the illustrated example, and may be any number and shape.

  Since the waist wall 1 of the present embodiment is a Balconi waist wall as described above, the upper surface 1A of the waist wall 1 is an inclined surface having a water gradient, as can be seen in FIG. The two lower surfaces 21E and the projecting piece 21F of the reinforcing portion 21 that are out of the arrangement position of the anchor portion 22 are adapted to the upper surface 1A of the waist wall 1 that is an inclined surface having such a water gradient. It has become.

  As described above, the respective anchor portions 22 are inserted into the holes 2 filled with the gel adhesive 3, and when the adhesive 3 is solidified, the anchor portions 22 are fixed and embedded in the waist wall 1 with the adhesive 3. And the anchor part 20 will be coupled to the waist wall 1. This coupling operation is performed for each anchor component 20 prepared for each column 11, and then the operation for covering each column 11 on the outside of the reinforcement 21 of each anchor component 20 is performed. 21 and the column 11 are coupled with the screw 30 described above.

  Thereafter, the handrail panel 13 shown in FIG. 1 is attached to the two struts 11 adjacent to each other via the brackets, and the base member 12A and the cover member 12B described above are attached to the upper ends of the struts 11, respectively. The construction work of the handrail 10 is completed by performing the work of crossing the top rail 12 made of

  In addition, before performing the operation | work which covers each support | pillar 11 on the outer side of the reinforcement part 21 of each anchor component 20, the fence-like assembly which consists of the support | pillar 11, the handrail panel 13, top rail 13, etc. is assembled first. After this, the respective struts 11 constituting the fence-like combination are put on the outer side of the reinforcing portions 21 of the respective anchor parts 20, and then the anchor parts 20 coupled to the waist wall 1. You may make it couple | bond the reinforcement part 21 and the support | pillar 11 with the screw 30 mentioned above.

  As described above, the anchor portion 22 of the present embodiment has a cylindrical shape that extends downward. Therefore, the dimension of the anchor portion 22 in the direction orthogonal to the length direction of the anchor portion 22 is the length of the anchor portion 22. It is smaller than the dimension of the reinforcement part 21 in the direction orthogonal to the vertical direction. Therefore, the diameter of the hole 2 formed downward in the upper surface 1A of the waist wall 1 for inserting the anchor portion 22 can be reduced, and the inside of the waist wall 1 as shown in FIG. It can prevent that the anchor part 22 interferes with the reinforcing material 4 arrange | positioned in this.

  Further, as described above, since the uneven portions 22A that increase the surface area of the anchor portions 22 are formed on the surfaces of the two anchor portions 22, in the uneven portions 22A in which the adhesive 3 is adhered and solidified around, A large resistance is generated against the anchor portion 22 coming out of the hole 2 of the waist wall 1, and thus the anchor portion 22 can be coupled to the waist wall 1 with a high strength.

  In addition, the adhesive for couple | bonding the anchor part 22 with the waist wall 1 can select arbitrary types according to the handrail installation site. That is, this adhesive may be a general resin-based adhesive, mortar or concrete, and is a fixing means that substitutes for the adhesive, which is solidified from a liquid or gel state. It may be one that locks into the hole or anchor part of the casing, and may be one that is originally shaped and locked to the hole or anchor part of the casing by being deformed. A combination of fixing means may be used.

  5A, 5B, 6C, and 6A and 6B, the anchor component 20 is a single member in which the reinforcing portion 21 and the anchor portion 22 described above are integrally formed. The process for manufacturing is shown.

  What is shown in FIG. 5 (A) is a flat plate 40 made of a steel plate such as a high-tensile steel plate. By bending the flat plate 40, the same cross-sectional shape has a length as shown in FIG. 5 (B). An anchor part material 41 that is continuous in the direction is manufactured. The cross-sectional shape of the anchor part material 41, in other words, the shape of the cross-section orthogonal to the length direction of the anchor part material 41 is the same cross-sectional substantially channel shape as the reinforcing portion 21 described above. The anchor component material 41 has the same bent cross-sectional shape continuous in the length direction.

  After the anchor part material 41 having such a cross-sectional shape is manufactured, as shown in FIG. 5C, the length of the anchor part material 41 is extended from one end 41A in the length direction of the anchor part material 41. By cutting out part of the entire width direction of the anchor part material 41 perpendicular to the length direction of the anchor part material 41, that is, in the present embodiment, the anchor part In the length direction of the anchor part material 41, the excision is performed by cutting out the center part in the width direction of the entire width direction of the anchor part material 41 perpendicular to the length direction of the anchor material 41. The part 41B that does not exist is the part that becomes the reinforcing part 21, and the part 41C that is excised is the part that becomes the anchor part 22. Further, by performing excision at the central portion in the width direction, two portions 41C to be the anchor portion 22 are left on both sides in the width direction of the portion 41D to be excised, and thus the anchor portion 22 is obtained. Two portions 41 </ b> C are left in this manner, and two portions 41 </ b> C are provided on the anchor component material 41.

  In addition, when performing the above-mentioned excision, this excision is performed leaving the projection 41F that becomes the projecting piece 21F described above. Further, in the present embodiment, as shown in FIG. 5C, a part in the depth direction orthogonal to the width direction in each portion 41C is also cut off.

  Next, as shown in FIG. 6A, by curling each portion 41C to be the anchor portion 22, these portions 41C are made the above-described cylindrical anchor portion 22, By performing a bending process on the protrusion 41F, the protrusion 41F is defined as a protrusion 21F. Further, as shown in FIG. 6 (B), the surface of each anchor portion 22 is crushed or cut at intervals in the length direction of the anchor portion 22, and further drilled. By performing the deformation process, the above-described uneven portion 22 </ b> A is formed on the surface of each anchor portion 22.

  As a result, the anchor component 20 in which the reinforcing portion 21 and the anchor portion 22 are integrally formed on one member is manufactured from the flat plate 40 in FIG. 5A. It is provided with two lower surfaces 21E and one projecting piece 21F of the reinforcing part 21 serving as a contact part.

  In addition, you may enlarge the intensity | strength of this boundary part by providing a buildup part and a thick part by welding, for example in the boundary part of the reinforcement part 21 and the anchor part 22. FIG.

  Further, an operation for forming the uneven portion 22A on the surface of the anchor portion 22 is performed at the stage of FIG. 5A, the stage of FIG. 5B, or the stage of FIG. The curl processing shown in FIG. 6A may be performed.

  Each of the anchor portions 22 shown in FIG. 7 is subjected to deformation processing such as bending processing or compression processing on the distal end portions of these anchor portions 22, so that these anchor portions 22 extend in the length direction of the anchor portion 22. A protruding portion 22 </ b> B protruding in the transverse direction perpendicular to the surface is provided. These protrusions 22B form concavo-convex portions formed on the surface of the anchor portion 22 in the embodiment shown in FIG. For this reason, as described above, when the anchor portion 22 is inserted into the hole 2 of the waist wall 1 filled with the adhesive 3 and the adhesive 3 is solidified, the anchor portion 22 of the waist wall 1 is formed in the protruding portion 22B. As a result, a large resistance force against pulling out of the hole 2 is generated, whereby the anchor portion 22 can be coupled to the waist wall 1 with a high strength.
