Description

  The present invention relates to a decorative column structure. For example, in an entrance porch such as a house, the present invention relates to a decorative pillar structure such as a porch pillar that supports an entrance fence.

In general houses and the like, for example, as a device for improving the design of the entrance porch, construction is performed to design the porch pillar that supports the entrance porch.
Conventionally, these constructions have been performed by spraying paint, pigments, or the like, but in recent years, construction has been performed in which a fixture is fixed to a column core and a decorative column member is attached to the fixture.

For example, Patent Literature 1 discloses a core pillar having a square cross section, a pair of decorative cover members that are halved along the longitudinal direction of the core pillar, and covers the core pillar from the opposite side, and the pair of decorative cover members. An assembly-type decorative pillar is shown that includes a pair of attachment members that connect the attachment members at the butt joints and screw nails that secure the attachment members to the core pillar.
The both ends of the decorative cover member are formed with fitting grooves in which the both ends of each mounting member are accommodated.

  At the time of construction, both decorative cover members are combined with the core pillar interposed therebetween. As a result, a screw nail operating gap that is continuous in the longitudinal direction of the core column is formed between the joint surfaces of both decorative cover members. Subsequently, a screw nail inserted from a screw nail operating gap at a predetermined height position by inserting an attachment member downward from an upper end of a fitting groove formed facing between the joint surfaces of both decorative cover members. Is screwed into the core post through the mounting member. Thereby, the decorative cover member is fixed to the core column.

JP-A-9-132952 (see FIGS. 8 to 10)

  In the structure of the assembly type decorative pillar disclosed in Patent Document 1 described above, in the state where the two decorative cover members are combined with the core pillar interposed therebetween, the two decorative cover members are not supported elsewhere, so the mounting member is a screw nail. If the decorative cover member is not supported until it is screwed into the core pillar, the decorative cover member may come off. Therefore, workability is bad.

In the embodiment described in Patent Document 1 (the first embodiment described in FIGS. 1 to 7), the attachment member is formed to have a length substantially equal to the length of the core column, and this is temporarily attached to the core column with a screw nail. After stopping, the fitting grooves facing each other of the decorative cover members are fitted into the wing pieces at both ends of the mounting member. After that, a method has been proposed in which the screw nails are finally tightened to fix both decorative cover members to the core column.
However, in the case of this method, the facing fitting grooves of both decorative cover members must be fitted over the entire length of the blade piece at the both ends in the width direction of the mounting member that is long in the vertical direction (the full length in the vertical direction). However, workability is poor.

  An object of the present invention is to solve such a conventional problem and provide a decorative column structure that is easy to construct.

The decorative column structure of the present invention includes a column core material, a pair of decorative column members having a joint surface along the longitudinal direction of the column core material and covering the outer periphery of the column core material facing each other, and the decorative columns. A fixture for attaching a member to the column core material, the column core material is formed in a square column shape, and each decorative column member is formed on a joint surface facing each other, and at least a part of the column core material is provided. A recess having a rectangular cross-section to be stored, and a sandwiched portion formed between the recess and the joint surface, the sandwiched portion being formed on the inner surface of the recess and intersecting the inner surface A first sandwiched surface, and a second sandwiched surface formed on the joint surface and substantially perpendicular to the joint surface, wherein the fixture elastically sandwiches the sandwiched portion of the decorative column member Fixed to the column core member between the elastic sandwiching portion and the facing joint surfaces of the pair of decorative column members And a fixing piece which, the resilient clamping unit includes a first elastic holding pieces for holding the integrally formed first clampable surface resiliently from said fixing piece, integrally formed from the fixed piece And a second elastic clamping piece that elastically clamps the second clamping surface, and the fixing piece is detachably fixed to the column core member by a fastener.

According to this configuration, the clamped portion of the one decorative column member is clamped by the clamped portion of the fixture, and the fixture is attached to the decorative column member. The decorative column member in this state is fitted with the concave portion facing the column core material. Then, the fixing piece of the fixture is inserted along the opposing side surfaces of the column core material. In this state, the fixing piece is fixed to the column core material by the fastening tool. The other decorative column member is similarly fixed to the column core material.
Therefore, since the pair of decorative pillar members can be fixed to the pillar core member one side at a time, the construction is simple. That is, since it is not necessary to hold a pair of decorative cover members as in the prior art, the construction is simple. Further, if the fastening tool is loosened, the fixing piece of the fixture can be removed from the column core material, so that even when the decorative column member is broken or damaged, it can be easily replaced.

The elastic clamping portion includes a first elastic clamping piece that elastically clamps the first clamping surface of the clamping portion, and a second elastic clamping piece that elastically clamps the second clamping surface of the clamping portion. Therefore, the decorative column member is unlikely to come off, and is difficult to be displaced with respect to the direction intersecting the fitting direction of the decorative column member (the recessed depth direction of the decorative column member).
That is, when a force in the direction of detachment is applied to the decorative column member, the first elastic clamping piece is formed on the inner side surface of the recess so as to intersect with the first clamping surface, so that the decorative column member is detached. Since it prevents it from moving, the decorative member is difficult to come off. When a force in a direction intersecting with the fitting direction (the depth direction of the concave portion of the decorative column member) is applied to the decorative column member, the second elastic sandwiching piece is formed on the joint surface substantially orthogonally to the second covering member. Since the decorative column member is prevented from moving in a direction intersecting the fitting direction (the concave depth direction of the decorative column member) in contact with the holding surface, the decorative column member can be prevented from being displaced.

In the decorative pillar structure according to the present invention, the first elastic clamping piece includes an extension formed by extending from the fixed piece between the pillar core member and the recess, and the first elastic pinion at the tip of the extension. A first clamping claw bent obliquely toward the clamped surface, and the second elastic clamping piece is bent at a substantially right angle from the fixed piece and faces the pair of decorative column members facing each other It is preferable to include a bent portion extending in between and a second clamping claw bent toward the outside after being bent at a substantially right angle from the front end of the bent portion.
According to this configuration, when the fixture is attached to the decorative column member, the fixture is attached to the decorative column member in a posture in which the first clamping claw and the second clamping claw of the fixture sandwich the sandwiched portion of the decorative column member. Insert into the clamping part. Then, the first clamping claw and the second clamping claw of the fixture are inserted while being elastically deformed in a direction away from each other by the sandwiched portion of the decorative column member. Eventually, when the tip of the first clamping claw reaches the first clamping surface formed on the inner surface of the recess, the first clamping claw is elastically restored and engaged with the first clamping surface. Thereby, the fixture is attached to the decorative column member in a state where the first clamping claw and the second clamping claw of the fixture clamp the sandwiched portion of the decorative column member.
Therefore, since the fixture can be attached to the decorative column member only by inserting the fixture into the sandwiched portion of the decorative column member, the workability can be further improved.

In the decorative column structure of the present invention, it is preferable that a sealing material is filled between the facing joint surfaces of the pair of decorative column members.
According to this configuration, since the sealing material is filled between the facing joint surfaces of the pair of decorative column members, it is possible to reliably prevent intrusion of rainwater and the like.

<Description of construction method of decorative pillar structure (see FIGS. 2 to 5, 6, and 7)>
At the time of construction, the elastic clamp 41 of the fixture 40 is inserted into the clamped portion 28 of one decorative column member 20, and the fixture 40 is attached to the decorative column member 20.
First, the fixture 40 is inserted into the sandwiched portion 28 of the decorative column member 20 with the first sandwiching claw 42B and the second sandwiching claw 43B of the fixture 40 sandwiching the sandwiched portion 28 of the decorative column member 20. Then, the first clamping claw 42B and the second clamping claw 43B of the fixture 40 are inserted while being elastically deformed in a direction away from each other by the sandwiched portion 28 of the decorative column member 20. Eventually, when the tip of the first clamping claw 42B reaches the first clamping surface 28A formed on the inner surface 21B of the recess 21, the first clamping claw 42B is elastically restored and engaged with the first clamping surface 28A. The

  As shown in FIG. 6, when the mounting work of the fixture 40 is performed on the sandwiched portions 28 on both sides sandwiching the recess 21 of the decorative column member 20, the first sandwiching piece 42 and the second sandwiching piece 42 of the fixture 40 are attached. With the piece 43 sandwiching the sandwiched portion 28 of the decorative column member 20, the fixture 40 is attached to the decorative column member 20.

  The decorative column member 20 in this state is fitted with the recess 21 facing the column core member 10. Then, the fixing piece 44 and the first elastic clamping piece 42 of the fixture 40 are inserted to predetermined positions along the opposing side surfaces of the column core member 10. In this state, the screw 46 is inserted into the screw insertion hole 45 of the fixed piece 44 and screwed into the column core member 10 (see FIG. 7). Thereby, one decorative pillar member 20 is attached to the pillar core member 10.

  Similarly, after inserting the elastic clamping part 41 of the fixture 40 into the clamped part 28 of the other decorative pillar member 20 and attaching the fixture 40 to the decorative pillar member 20, the decorative pillar member 20 in this state is attached to the pillar. It fits in the core material 10 and is fixed to the column core material 10 with screws 46. As a result, the remaining other decorative column member 20 is also attached to the column core member 10.

In this state, it is difficult for the decorative column member 20 to come off, and it is possible to prevent a deviation from occurring in the direction intersecting the fitting direction of the decorative column member 20 (the depth direction of the recess 21 of the decorative column member 20). it can.
In other words, when a force in a direction away from the decorative column member 20 is applied, the first elastic clamping piece 42 is formed to intersect with the inner side surface 21B of the recess 21 and abuts on the first sandwiched surface 28A. Is prevented from coming off.
When a force in a direction intersecting with the fitting direction (the depth direction of the recess 21 of the decorative column member 20) is applied to the decorative column member 20, the second elastic clamping piece 43 is formed substantially orthogonal to the joining surface 20A. Since it contacts the second sandwiched surface 28B, the decorative column member 20 is prevented from shifting with respect to the direction intersecting the fitting direction.

Thus, after attaching a pair of decorative column members 20 to the column core member 10 via the fixture 40 so as to cover the outer periphery of the column core member 10, the joint surfaces of the pair of decorative column members 20 facing each other. A sealing material 70 is filled between the butted ends in between, and a water stop treatment is performed.
The sealing material 70 includes a wet sealing material and a dry sealing material, and a dry sealing material is preferable. Silicon-based, urethane-based, acrylic-based, etc. can be adopted as the dry sealant. Among them, an elastic sealing material such as EPDM (ethylene / propylene rubber) can be preferably used.

<Effect of embodiment>
(1) Since the pair of decorative pillar members 20 can be fixed to the pillar core member 10 one side at a time, the construction is simple. That is, since it is not necessary to hold a pair of decorative cover members as in the prior art, the construction is simple.

(2) Since the fixture 40 can be attached to the decorative column member 20, the fixture 40 can be attached to the decorative column member 20 simply by inserting the fixture 40 into the sandwiched portion 28 of the decorative column member 20. The workability can be further improved.

(3) The elastic pinching portion 41 of the fixture 40 includes a first elastic pinching piece 42 that elastically pinches the first pinched surface 28A of the pinched portion 28 of the decorative column member 20, and a second pinion of the pinched portion 28. Since the second elastic clamping piece 43 that elastically clamps the sandwiched surface 28B is provided, the decorative column member 20 is unlikely to come off, and the fitting direction of the decorative column member 20 (the recess depth direction of the decorative column member 20) ) Is less likely to shift in the direction that intersects.

(4) After the decorative column member 20 is assembled to the column core member 10, the fixing piece 44 of the fixture 40 can be removed from the column core member 10 by removing the sealing material 70 and loosening the screws 46. Even when the decorative column member 20 is broken or damaged, it can be easily replaced.
(5) Since the sealing material 70 is filled between the butted end portions of the pair of decorative column members 20, it is possible to reliably prevent intrusion of rainwater and the like.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, the shape of the decorative column member 20 is not limited to a semicircular shape, and may be a rectangular cross section, or may be a shape other than this. Further, the outer contour shape is not particularly limited.

  In addition, in the fixture 40, a rough surface treatment is performed on the inner surface side of the distal end portion of the second elastic clamping piece 43, or a serrated projection is formed, so that the frictional resistance with the sandwiched portion 28 of the decorative column member 20 is achieved. If it is enlarged, the decorative pillar member 20 can be held more firmly. Alternatively, the same effect can be expected by forming a groove or the like into which the tip of the second elastic clamping piece 43 is fitted in the sandwiched portion 28 of the decorative column member 20 with which the second elastic clamping piece 43 contacts.

  Moreover, in the said embodiment, although one board | plate material was bend | folded and formed the fixture 40, it is not restricted to this. For example, as shown in FIGS. 8 and 9, the fixture 40 may be configured by integrally joining two plate members. That is, the first member 40A in which the first elastic clamping piece 42 is integrally bent from the fixed piece 44, and the pair of second elastic clamping pieces 43 are integrally bent from the upper and lower end positions of the fixed piece 44. The two members 40B may be overlapped with each other at the fixed piece 44 portion, and the overlapping portion may be subjected to burring so as to integrally couple them to constitute the fixture 40. In this case, for the first member 40A having the first elastic clamping piece 42 that requires elasticity, a material having a smaller thickness than the second member 40B is used, or a spring material, a stainless material, a plated steel plate is used. For example, the decorative column member 20 can be securely clamped.

  The present invention can be applied to a structure of various decorative pillars used for general houses, such as a decorative pillar of balcony, in addition to being usable for a pouch pillar.
