Description

  The present invention relates to a fixing structure for a decorative pillar used in a building, and more particularly, to a fixing structure for attaching a decorative pillar divided into two with a hollow portion therein to a structural pillar of a building using a mounting bracket.

  A conventional two-piece decorative pillar is fixed to a structural pillar of a building using a long-sized drill screw or a tapping screw. However, since this method significantly reduces the appearance because a hole is made in the decorative column, a method of fixing the mounting bracket to the structural column and further fixing the divided decorative column to the mounting bracket is used. Became.

  For example, a mounting bracket is attached to each inner side of each of the decorative pillars divided in advance by bonding or the like. On the other hand, a mounting bracket is also attached around the structural column. First, one mounting bracket of the two-split decorative pillar is screwed to the mounting bracket on the structural column side with a screw. Thereafter, there is known a method of screwing the remaining mounting brackets of the two-piece decorative pillars to the mounting brackets of the divided portions fixed first. (For example, refer to Patent Document 1).

  In addition, for example, a protrusion that protrudes inward of each of the two-split decorative pillars is provided in advance. On the other hand, the mounting bracket to be mounted around the structural column is provided with a mounting portion into which the decorative column side protrusion is fitted. There is known a method in which the attaching portion can elastically hold the protruding portion, and the attaching portion is attached by inserting the protruding portion of the decorative pillar into the attaching portion on the attachment fitting side. (For example, refer to Patent Document 2).

  However, as in the method of Patent Document 1, it is technically difficult to attach the metal fitting to the inside of the decorative column by bonding or the like, and screwing with a screw or the like is difficult due to the strength of the material of the decorative column. It was. In addition, align the screw holes of the metal fittings attached to the structural pillar side and the screw holes of the metal fittings attached to the inside of the two-piece decorative pillar, which is a heavy object, while supporting the weight of the two-piece decorative pillar. The work of stopping was also difficult with a small number of people such as one or two people. Furthermore, after fixing one of the two-piece decorative pillars to the metal fitting on the structural column side, the screw holes of the other two-piece decorative pillar metal fittings, which are also heavy objects, are replaced with the screw holes of the two-piece decorative pillar metal fittings already fixed. It was difficult for a small number of people to align and fasten the screws while supporting the weight. In addition, this method requires many man-hours such as screwing and requires a lot of time for attachment and removal.

  Moreover, in order to improve "the operation | work which fixes the 2 division | segmentation decorative pillar which is a heavy article with a small number of people to an attachment metal fitting" in the method of above-mentioned patent document 1 is expanded, the fixation range to an attachment metal fitting is expanded, A method for increasing the degree of freedom of attachment is conceivable. However, when the degree of freedom of attachment is increased, the outer periphery of the two-piece decorative column is flush with the mounting bracket while aligning each facing surface so that no step occurs in the opposite part between the two divided decorative columns. Need to be fixed.

  In addition, the method of elastically holding the protruding portion of Patent Document 2 is to temporarily fix the decorative pillar, which is a heavy object, only by the elasticity of the metal fitting, and not to fix it permanently. In order to fix permanently, it was necessary to fix using the adhesive agent for construction materials, the screw stop using the conventional drill screw, etc. However, when an adhesive is used, it cannot be redone and cannot be removed later. Further, when a tapping screw or the like is used, there is a possibility that the appearance is greatly deteriorated because a hole is made in the structural column. Also, when holding the protrusion elastically in the mounting part, when the accuracy of fixing the mounting part to the mounting bracket cannot be increased, or when there is variation in the elastic stress in each pressing direction of the mounting part, There was a case where a step was generated at the facing portion between the two split decorative columns.

  Therefore, in order to solve the above-described problems, the present invention enables accurate alignment that does not generate a step on the outer periphery when the two-piece decorative pillar is installed, and can be easily installed even by a small number of people. It aims at providing the fixation structure of the decorative pillar which improved the beauty | look by suppressing.

By not holding the interval between the other side portions of the two-divided column body below a predetermined value by the holding portion, the interval between the inner peripheral side surface of the other side portion and the outer peripheral surface of the structural column can be set to a predetermined value. In that case, the distance between the outer peripheral surface of the structural column and the inner peripheral side surface of one side is secured by the distance holding portion on the other side from the sum of the distances between each side of the two-divided column and both sides of the structural column. It is the remainder after subtracting the predetermined value. Therefore, the outer peripheral surface when the two-divided column body is mounted with the structural column sandwiched between the predetermined value of the interval holding unit and the remainder obtained by subtracting the predetermined value from the sum of the intervals between both sides as close as possible. Can be suppressed within a predetermined range.

Preferably, as in the present invention according to claim 2, the interval holding portion has a predetermined value that is approximately ½ of the sum of the intervals between the outer peripheral surfaces on both sides of the structural column and the both side surfaces on the inner periphery of the split column. You may make it form so that it may become.
In this embodiment, the predetermined value of the interval holding unit is set to be approximately ½ of the sum of the intervals between both sides of the two-divided column body and the both sides of the structural column, so that the predetermined value secured in the other interval holding unit is obtained. The remainder obtained by subtracting the value can also be reduced to approximately ½ of the sum of the distances between both sides of the structural column, and the distance between both sides becomes the same. Therefore, the gap | interval holding | maintenance part can eliminate the level | step difference of the outer peripheral surface at the time of attaching a 2 division | segmentation pillar body on both sides of a structure pillar.

Preferably, as in the present invention according to claim 3, the elastic body may be provided on the mounting bracket.
In this embodiment, by providing the elastic body on the mounting bracket, the insertion of the elastic body can be facilitated, and the number of mounting steps for the two-divided column body can be reduced.

The entrance porch is a space that is generally raised by several steps from the approach portion under the eaves in front of the entrance door. The decorative pillar 1 is provided by vertically connecting the upper part of the base part of the entrance porch and the lower part of the bag. In addition, the decorative pillar 1 may be used for a veranda or the like.

  The two-divided column body 11 is a cement-based extrusion molded body in which the decorative column 1 used for a building such as a house as described above is vertically divided into two equal parts, and the specific gravity is about 0.7 to 1.5. Consists of. Hereinafter, when one of the two divided column bodies 11 is shown, it is called a two divided column body 11a, and when the other two divided column bodies 11 are shown, it is called a two divided column body 11b. A cavity (hollow part 95) is formed inside the two-divided pillar body 11 so as to include the structural pillar 91 of the building. The two-divided columnar body 11 that is attached to be opposed to each other with the structural column 91 interposed therebetween is formed so as to be provided with recesses 71/72 that engage with the mounting bracket 31 on both side portions 14/15 that sandwich the cavity 95.

  The first facing surface 12 is a facing surface of one side portion 14, and no recess is formed on the facing surface. The surface shape of the first facing surface 12 is such that the surface of the corresponding side of the first linear convex portion 41a of the convex portion 41 is positioned so that the two-divided column body 11 can be positioned by contacting the convex portion 41. It is formed according to the surface shape. On the other hand, the second facing surface 13 is a facing surface of the other side portion 15 across the cavity portion 95 of the two-divided column body 11, and a concave portion 72 is formed on this facing surface. The surface shape of the second facing surface 13 is such that the surface of the corresponding side of the first linear convex portion 41a of the convex portion 41 is positioned so that the two-divided pillar body 11 can be positioned by contacting the convex portion 41. It is formed according to the surface shape.

  The 1st opposing surface 12 and the 2nd opposing surface 13 are the division | segmentation sections into which the 2 division | segmentation pillar body 11 was divided vertically, and the two 2 division | segmentation column bodies 11 arrange | positioned around the one structural pillar 91 are as follows. The first facing surface 12 and the second facing surface 13 are arranged so as to face each other with a gap therebetween. The gap between the first facing surface 12 and the second facing surface 13 is usually filled with a caulking agent or the like for filling a hole or concealed with a dry joint material. Since the caulking agent or the like has an adhesive action on the adherend surface when solidified, it can be considered as an adhesive. That is, the gap between the first facing surface 12 and the second facing surface 13 is filled with the adhesive. In the case of a dry joint material, it is easy to remove or replace the decorative pillar 1.

  The 1st side part 14 is one side part on both sides of the cavity part 95 in the 2 division | segmentation pillar body 11, and has the recessed part 71 in an internal peripheral side surface. The second side portion 15 is the other side portion sandwiching the hollow portion 95 in the two-divided column body 11, and has a concave portion 72 on the second facing surface 13 with the other two-divided column body 11.

On the other hand, the second inner peripheral side surface 22 is a side surface on the inner peripheral side of the other side portion 15 sandwiching the hollow portion 95 of the two-divided column body 11, and no concave portion is formed on the inner peripheral side surface.

  The mounting bracket 31 is formed so that the two-divided column body 11 can be fixed to the structural column 91 by using two mounting brackets 31 at one position across the structural column 91 of the building. The two mounting brackets 31 are formed in the same shape so that they can be fixed by screwing a fixing screw 81 into the fixing screw hole 32 with the structural column 91 of the building interposed therebetween. The fixing screws 81 are attached to a plurality of places including the place. The interval for installing the mounting bracket 31 is provided in the vertical direction of the structural column 91, for example, at an interval of about 700 mm.

  The mounting bracket 31 positions the two-divided column 11, and the convex 41 that engages the concave 72 of the two-divided column 11, the convex 51 that engages the concave 71 of the divided column 11, and 2 It has the elastic body 61 which presses the 2nd inner peripheral side surface 22 of the one side part 15 of the division | segmentation pillar 11 to an outer side direction. The mounting bracket 31 is formed by extrusion molding such as aluminum. By forming the mounting bracket 31 by extrusion molding, the manufacturing can be facilitated and the manufacturing cost can be reduced. Since the two mounting brackets 31 have the same shape, the manufacturing cost and the number of parts can be reduced. it can. Note that the convex portion 51 and the elastic body 61 that require elastic force are preferably formed of a stainless steel plate or the like, and are integrally formed using a substrate portion or the convex portion 41 made of an aluminum extruded body and the rivets 82 and 83. It becomes.

  The fixing screw hole 32 is a hole for attaching the two mounting brackets 31 that are mounted to face each other with the structural column 91 interposed therebetween, with the fixing screw 81. In the case where the fixing screw 81 is of a type such as a drill screw or a tapping screw that is screwed and tightened while cutting a groove, it is not necessary to provide the fixing screw hole 32 in advance, and the mounting bracket 31 is screwed. Sometimes formed. If the fixing screw 81 is not a type that is tightened while cutting the screw groove, a screw groove is formed in advance inside the fixing screw hole 32. When a bolt is used together with a nut as the fixing screw 81, it is not necessary to previously form a screw groove inside the fixing screw hole 32, and a simple circular opening may be used.

  The convex portion 41 is formed in a bowl shape that can be engaged with the concave portion 72 by, for example, the two-divided column body 11 and the second facing surface 13. In more detail, the convex part 41 is arrange | positioned inside the 1st linear convex part 41a arrange | positioned from the structural pillar 91 to the entrance part of the recessed part 72 of the 2 division | segmentation pillar 11 and the 1st linear recessed part 72a.

In the present embodiment, the inner peripheral side surface 22 of the side portion 15 that is pressed by the elastic body 61 is pushed outward by the elastic body 61, whereby the inner peripheral side surface 21 of the side portion 14 that is not pressed by the elastic body 61. The two-divided column body 11 can be fixed by engaging the concave portion 71 with the tip portion of the substantially linear convex portion 51.

  The concave portion 72 of the side portion 15 is provided on the second facing surface 13 of the side portion 15 with the other two-divided column body 11. The concave portion 72 includes a first linear concave portion 72a formed on the back side at a right angle from the entrance portion, a second linear concave portion 72b formed on the inner side from the back end portion of the first linear concave portion 72a, It is formed in a bowl shape having a bent recess 73 between the first linear recess 72a and the second linear recess 72b. By fixing the concave portion 72 to a bent shape that is bent once by the concave portion 73 and engaging with the convex portion 41 of the vertical shape, the fixing of the two-divided column 11 to the metal fitting 31 can be made more rigid.

  The fixing screw 81 is a screw for attaching the two mounting brackets 31 with the structural column 91 interposed therebetween. The fixing screw 81 uses various types such as a drill screw or a tapping screw that is tightened while making a screw hole and cutting a groove, a normal type that is not tightened while cutting a screw groove, and a bolt and nut type. be able to. The fixing screw hole 32 is formed in accordance with the screw type as described above.

  The structural column 91 is, for example, a prismatic column of a light-weight steel house or a prismatic column of a wooden house, and has sufficient strength to support the weight of a structure such as a roof of a house, It has sufficient strength for fixing the relatively heavy two-divided column 11 to the periphery.

  The cavity 95 is a cavity formed on the inner side of the two-divided column body 11 and accommodates the main portions of the structural column 91 and the mounting bracket 31.

FIGS. 3A to 3G are diagrams showing a procedure for attaching the two-divided column body 11 of FIG. 2 to the structural column 91.
In FIG. 3 (a), two mounting brackets 31 are attached to a plurality of locations (equal intervals such as every 700 mm) of the structural column 91 by using two fixing brackets 31 at each location so as to sandwich the structural column 91. The two split pillars 11a are brought close to the mounting bracket 31.
In FIG.3 (b), after making the side part 14 of the 2 division | segmentation pillar 11a contact the 1st opposing surface 12 to the convex part 41 first, and making the inner peripheral side surface 21 contact the convex part 51 in FIG. The side portion 15 of the two-divided column 11a is brought into contact with the other convex portion 41 while pressing the elastic body 61.

In FIG. 3C, the two-divided column body 11 a is slid in a direction to ease the pressing of the elastic body 61, and the concave portion 71 of the inner peripheral side surface 21 in the side portion 14 is engaged with the convex portion 51, and the side The convex portion 41 is engaged with the concave portion 72 of the portion 15.
In FIG. 3D, the two-divided column body 11 b is brought closer to the mounting bracket 31 from the opposite side of the two-divided column body 11 a with the structural column 91 interposed therebetween.

In FIG.3 (e), after making the side part 14 of the 2 division | segmentation pillar 11b contact the 1st opposing surface 12 to the convex part 41 first, and making the inner peripheral side surface 21 contact the convex part 51 in FIG. The side portion 15 of the two-divided column body 11b is brought into contact with the other convex portion 41 while pressing the elastic body 61.
In FIG. 3 (f), the two-divided column body 11 b is slid in a direction to relieve the pressing of the elastic body 61, and the concave portion 71 of the inner peripheral side surface 21 in the side portion 14 is engaged with the convex portion 51, and the side The convex portion 41 is engaged with the concave portion 72 of the portion 15.
In FIG. 3G, the two-divided column body 11 a and the two-divided column body 11 b are attached to the mounting bracket 31 with the structural column 91 interposed therebetween. In this case, the two-divided column body 11a and the two-divided column body 11b are either the position where the convex portion 51 abuts against the concave portion 71 or the position where the convex portion 41 abuts against the concave portion 72 by the pressing force of the elastic body 61. It is fixed at the position where it hits first.

  As described above, in the present embodiment, the inner peripheral side surface 22 of the side portion 15 on the side pressed by the elastic body 61 in the two-divided column body 11 is pressed outward by the elastic body 61. On the other hand, the convex portion 41 of the mounting bracket 31 is engaged with the concave portion 72 of the two-divided column body 11. Accordingly, the portion on the inner peripheral side surface 22 side of the side portion 15 is sandwiched between the elastic body 61 and the convex portion 41 of the mounting bracket 31. Further, the inner peripheral side surface 21 of the side portion 15 is sandwiched between the convex portion 51 by the convex portion 51 engaging the concave portion 71 and the portion on the first facing surface 12 side of the side portion 14. Thereby, the 2 division | segmentation pillar 11 can be fixed easily.

  By forming the mounting bracket 31 and the two-divided column body 11 in this way, the two-divided column body 11a and the two-divided column body 11b can be attached to the structural column 91. However, due to reasons such as dimensional errors of mounting brackets, variations in elastic force, and dimensional errors of cement-based extrusion moldings, the step size D1 on the facing surfaces of the two-divided column 11a and the two-divided columns 11b (see FIG. 2) There is a problem that it is difficult to completely eliminate. If the step dimension D1 is present, the beauty of the decorative pillar 1 is impaired, and thus it is required to suppress D1 within a range that does not affect the beauty.

  Therefore, in order to eliminate the adverse effect of the aesthetic appearance due to the step dimension D1, the inventor between the outer peripheral surface of the structural column 91 and the inner peripheral side surface 21 of the side portion 14 not pressed by the elastic body 61 in the two-divided column body 11, It was considered to insert an interval holding part for holding a predetermined interval. Thereby, the space | interval of the outer peripheral surface of the structure pillar 91 and the inner peripheral side surface 21 which is not pressed by the elastic body 61 in the 2 division | segmentation column body 11 can be prevented from becoming below a predetermined value. However, it is not easy to insert the interval holding portion between the outer peripheral surface of the structural column 91 and the inner peripheral side surface of the two-divided column body 11 which is a heavy object at the construction site. Therefore, in the present invention, the interval holding portion is provided on a fixed plate that is inserted into either or both of the upper and lower sides of the decorative column 1, and the fixed plate is inserted into either or both of the upper and lower sides of the decorative column 1, thereby It was comprised so that it could insert between the outer peripheral surface of the structural pillar 91, and the inner peripheral side surface of the 2 division | segmentation pillar 11.

  4 is a plan view showing a state before the fixing plate shown in FIG. 1 (b) is attached, and FIG. 5 is a plan view showing a state after the fixing plate shown in FIG. 1 (b) is attached. is there.

  In the fixing plate 101, the shape of the inner peripheral side surface 102 is substantially the same as the outer peripheral shape of the structural column 91, and the shape of the outer peripheral side surface 103 is the same as the outer peripheral shape of the cross section obtained by dividing the decorative column 1 formed without a step into two equal parts. Formed. The fixed plate 101 is arranged (inserted) in a gap between at least one of the upper end or the lower end of the decorative pillar 1 and the building. At that time, the fixing plate 101 is guided and inserted into the structural column 91 having a rectangular cross section so as to cross the two divided column bodies 11a / 11b half by half and to be in an orthogonal position. For example, when the structural column 91 is a C-shaped steel of the prefabricated construction method, the guide is set to the pair of two faces facing each other in the square cross section, which half of the two divided column bodies 11a / 11b. Inserted. Hereinafter, the two fixed plates 101 inserted from the opposite side of the structural pillar 91 are referred to as a fixed plate 101a and a fixed plate 101b, respectively.

  The interval holding unit 110 is in contact with the inner peripheral side surface 21 and the connection portion 111 connected to the fixed plate 101, the stopper 112 that suppresses the movement of the side portion 14 of the two-divided column 11 to the inner peripheral side surface 21. A contact surface 113 is provided and is fixed on the fixed plate 101 by a rivet 121. A dimension L3 from the structure column 91 side of the connecting portion 111 to the contact surface 113 is set to a predetermined interval of the present embodiment.

  The inner peripheral side shape of the connecting portion 111 is the same as the outer peripheral shape of the structural column 91. On the fixed plate 101, the interval holding unit 110 includes an outer side of a surface of the structural column 91 where the elastic body 61 is not disposed (a surface opposite to a surface where the elastic body 61 is disposed) and an elastic body 61 of the two-divided column body 11. It is arrange | positioned and fixed so that it can be located between the inner peripheral side surfaces 21 of the side part 14 which is not pressed by.

  Thereby, the elastic body 61 and the space | interval holding | maintenance part 110 are each arrange | positioned on the outer side of the surface in which the structural pillar 91 opposes. Accordingly, the one side 15 of the two-divided column 11 is subjected to a stress that pushes outward by the elastic body 61, but the interval of the other side 14 of the two-divided column 11 is less than a predetermined value by the interval holding unit 110. By not becoming, the space | interval of the outer peripheral surface of the structural pillar 91 and the inner peripheral side surface 21 of the other side part 14 can be maintained at a predetermined value.

  In this case, the distance between the outer peripheral surface of the structural column 91 and the inner peripheral side surface 21 of the one side portion 14 is the sum of the intervals between the side portions 14/15 of the two-divided column body 11 and both sides of the structural column 91 (L1). -L2) is a remainder obtained by subtracting a predetermined value secured by the interval holding unit 110 on the other side. Accordingly, when the two-divided column body 11 is attached with the structural column 91 sandwiched therebetween by bringing the predetermined value of the interval holding unit 110 and the remainder obtained by subtracting the predetermined value from the sum of both side intervals as close as possible. Can be suppressed within a predetermined range.

  In this embodiment, in order to suppress the step of the outer peripheral surface within a predetermined range, the predetermined value is, for example, between the outer peripheral surfaces on both sides of the structural column 91 and the both side surfaces 21 and 22 of the inner periphery of the two-divided column body 11. It is formed to be approximately ½ of the sum of the intervals.

  More specifically, for example, the spatial distance dimension of the hollow portion 95 between the inner peripheral side surface 21 of the side portion 14 and the inner peripheral side surface 22 of the side portion 15 in the two-divided column body 11 is L1, and the hollow portion 95 is The dimension of the L1 direction of the structural pillar 91 arrange | positioned is set to L2. In that case, the predetermined value of the space | interval holding | maintenance part 110 is made into the other side by making it 1/2 of the sum (L1-L2) of the both-sides space | interval of each side part 14/15 and the structure pillar 91 of the 2 division | segmentation pillar 11 The remainder obtained by subtracting the predetermined value secured by the interval holding unit 110 can be reduced to ½ of the sum (L1−L2) of the interval between both sides of the structural column 91, and the interval between both sides becomes the same. In other words, in the present embodiment, by inserting the fixed plate 101c and the fixed plate 101d from the opposite sides with respect to the structural column 91, the inner peripheral side surface 21 of the side portion 14/15 of the structural column 91 and the two-divided column body 11 is obtained. The interval dimension with / 22 can be made constant. Therefore, it is possible to eliminate the step on the outer peripheral surface when the two-divided column body 11 is attached with the structural column 91 sandwiched therebetween by the interval holding unit 110.

  The interval holding unit 110 can be easily positioned by being provided on the fixed plate 101 guided by the structural column 91. As a result, the man-hours for attaching the two-divided column body 11 can be reduced. Moreover, in this embodiment, by using the fixed plate 101, it is possible to prevent a gap from being formed between the top and bottom of the decorative pillar 1 and the building, and the appearance can be improved.

  As described above, according to the fixing structure of the decorative pillar 1 according to the present embodiment, the attaching work and the removing work including the positioning and fixing to the mounting bracket 31 of the two-divided pillar body 11 are reduced without making a hole in the structural pillar 91. Even the number of persons can easily carry out, and furthermore, by using the fixing plate 101, it is possible to easily fix more firmly and to remove it easily. Further, since the two mounting brackets 31 can be manufactured in the same shape by aluminum extrusion or the like, the increase in material and man-hour cost can be reduced.

Second Embodiment
FIG. 6 is a cross-sectional view and a side view of the decorative pillar according to the second embodiment of the present invention.
The main differences of this embodiment from the first embodiment are the following points, and the configuration, operation, and effects other than the differences are the same as those of the first embodiment.

  In the present embodiment, the two fixed plates 101 arranged to face each other are referred to as a fixed plate 101c and a fixed plate 101d. Further, in the present embodiment, by inserting the fixed plate 101c and the fixed plate 101d from the opposite sides to the structural column 91, the inner peripheral side surface 21 of the side portion 14/15 of the structural column 91 and the two-divided column body 11 is provided. The interval dimension with / 22 can be made constant.

  The interval holding part 110 a contacts the connecting part 111 a connected to the fixed plate 101, the stopper 112 a that prevents the side part 14 of the two-divided column 11 11 from moving to the inside of the inner peripheral side face 21, and the inner peripheral side face 21. A contact surface 113a is provided.

  On the fixed plate 101, the interval holding unit 110 a continuously connects the inner peripheral side surface 21 of the side portion 14 in one of the two divided column bodies 11 and the inner peripheral side surface 22 of the side portion 15 in the other two divided column bodies 11. By fixing with the contact surface 113a of the stopper 112a, the space | interval with the outer peripheral surface of the structural pillar 91 can be made constant. Therefore, in the present embodiment, the step on the outer peripheral surface of the two-divided column body 11 can be suppressed only to the difference in dimensions with the side portion 15 of the side portion 14.

  Further, in each of the above embodiments, the case where the mounting bracket 31 of the present invention is used for the structural column 91 of the prismatic column of the entrance porch of the lightweight steel house has been described, but the technical scope of the present invention is described in the above embodiment.
