Description

  The present invention relates to a decorative material for pillars used in general residential buildings and the like. More specifically, the present invention relates to a structure for fixing a decorative material around a pillar core material that bears a load.

  When constructing a pillar in a building such as a house, a core material that bears a load is made of a high-strength material such as a steel frame, and its outer surface is covered with a decorative material. And also about the method of fixing a decorative material around a pillar core material, in order to improve work efficiency, various structures are proposed conventionally.

  In Patent Document 1, a mounting bracket is screwed to a pillar core body, and a decorative material is pushed into the mounting bracket from outside to fit together. Moreover, in patent document 2, the decorative material is being fixed with the adhesive agent with respect to the base material fixed to the column core.

  However, in the attachment structures disclosed in Patent Documents 1 and 2, the decorative material can be easily and efficiently attached, but it is not considered that it can be easily removed. In other words, in order to remove the cosmetic material once attached, it is necessary to destroy it.

  On the other hand, in patent document 3, in the structure which consists of two makeup | decoration materials connected using a male-female joint around a pillar core body, in order to make "play" which causes the rattle after an assembly | attachment unnecessary. Ingenuity is disclosed. For this purpose, one end of each of the two decorative materials is connected in a hinged manner, and the other ends are connected to each other while being rotated so as to wrap the column core.

  In Patent Document 3, it is possible to remove the fixed decorative material, but since the convenience at that time is not considered, work that is not originally planned such as forcibly deforming one decorative material Therefore, of course, work efficiency is poor.

  As described above, the conventionally proposed column decorative material cannot be easily removed once it is attached to the column core. For example, when it is necessary to check the strength of the column core material or to replace it for refurbishment, conventional column decorative materials cannot cope with it well, and work that is broken or inefficient is forced.

  In view of the above-described conventional circumstances, an object of the present invention is to provide a mounting structure capable of firmly fixing a decorative material around a pillar core material with a simple operation and easily removing it if necessary. It is.

  In the decorative material mounting structure of the present invention, the decorative material fixing base is attached to the column core material, and the first decorative material piece and the second decorative material piece are fixed to the decorative material fixed base to cover the column core material.

The decorative material fixing base includes a first fixture and a second fixture. Each fixture includes “an elastic support protrusion that rotatably supports one piece of decorative material” and “an elastic holding portion that elastically holds the other piece of decorative material”.
The elastic clamping portion of each fixture is composed of “a hook having an L-shaped portion at the tip” and “an elastic piece biased toward the L-shaped portion”.

  Each of the first decorative material piece and the second decorative material piece is formed with a recessed portion for receiving the L-shaped portion, and the recessed portion includes a hooking groove extending in a direction substantially perpendicular to the depth direction.

  While supporting one side of the first decorative piece with the elastic support protrusion of the first fixture, the first decorative piece is rotated so that the L-shaped portion at the tip of the hook of the second fixture is the first decorative material. When inserted into the recess of the piece, the elastic piece of the second fixture presses and urges the first decorative material piece toward the L-shaped portion, so that the folded-back portion of the L-shaped portion becomes the hook groove of the recessed portion. Engage.

  While supporting one side of the second decorative material piece with the elastic support protrusion of the second fixture, the second decorative material piece is rotated so that the L-shaped portion at the tip of the hook of the first fixture is the second decorative material. When fitted into the recess of the piece, the elastic piece of the first fixture presses and urges the second decorative material piece toward the L-shaped portion, so that the folded-back portion of the L-shaped portion becomes the hooking groove of the recessed portion. Engage.

In the mounting structure of the present invention having the above-described configuration, when fixing the first and second decorative material pieces, the L-shaped hook tip is rotated while rotating the decoratively supported decorative piece. It is only necessary to fit the portion into the recess of the decorative piece. When working up to this state, the elastic piece presses and urges the decorative piece, so that the folded portion of the L-shaped portion engages with the hook groove provided at the bottom of the concave portion, thereby preventing reverse rotation of the decorative piece. And fixing is completed.
In this state, the other side of the decorative piece is clamped by the elastic clamping portion, and the elastic support protrusion presses and biases the decorative piece to the opposite side, so that the decorative piece is firmly fixed. Is done.

  On the other hand, when removing a fixed piece of decorative material, the piece of decorative material is slid against the urging force of the elastic piece, and the folded portion of the L-shaped part is pulled out from the catching groove. Can be removed.

  As described above, according to the mounting structure of the present invention, it is possible to easily and firmly fix the decorative material, and when it is necessary to check the strength of the column core material or to replace it for refurbishment. This can be easily dismantled. That is, it is possible to satisfy both conflicting demands of “easy and strong fixation” and “easy removal”.

  Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view for schematically explaining the mounting structure of the present invention.

<< Schematic configuration: Fig. 1 >>
The column core material 10 is made of a metal material such as a square steel material or an H-type steel material, a prismatic wood or other high-strength material, and bears a load acting on the column. A decorative material fixing base 40 is attached to the column core material 10, and the first decorative material piece 60 and the second decorative material piece 70 are fixed via this. The decorative material fixing base 40 includes a first fixture 20 and a second fixture 30.

Thus, in the present invention, the decorative material that gives the appearance decoration is attached to the column core member 10 that bears the load via the fixed base 40. In the example shown in FIG. 1, two sets of the decorative material fixing base 40 are provided on the upper and lower sides. However, an appropriate number is provided according to the length of the column, and in the case of a long column, three or more sets are required. In some cases.
FIG. 1 is a schematic view for clarifying the positional relationship of each member. The specific configuration of each member and details of the attachment procedure will be described with reference to FIG.

≪Coupling material fixing base 40: FIG. 2≫
FIG. 2 is a cross-sectional view orthogonal to the column core member 10 and shows the structure of the first fixture 20 and the second fixture 30 in detail. The first fixture 20 and the second fixture 30 constitute a decorative material fixing base 40.
In the illustrated example, the first and second fixtures 20 and 30 have the same structure. However, for convenience of explanation, both are referred to as “first fixture 20” and “second fixture 30”. Call and distinguish.

  The first fixture 20 and the second fixture 30 are connected face to face and fixed around the pillar core material 10. In the illustrated example, the column core member 10 is fixed from the outer periphery by connecting both with a screw member. The two fixtures 20 and 30 may be directly fixed to the column core member 10 individually. In view of workability, such as not being screwed directly to the column core material, it is preferable to connect both with a screw member so that the column core material 10 is tightened from the outer periphery.

  The first fixture 20 includes an elastic support protrusion 21 a and an elastic clamping portion 25. As will be described in detail later, the elastic support protrusion 21a rotatably supports one decorative material piece 60, and the elastic clamping portion 25 elastically holds the other decorative material piece 70.

In the illustrated example, the first fixture 20 has a curved elastic plate 21 fixed to a main body 20a having a substantially L-shaped cross section with a rivet material r. The free end of the elastic plate 21 functions as the elastic support protrusion 21a.
The elastic clamping unit 25 includes a hook 24 and an elastic piece 23.

The hook 24 is erected on the main body 20a of the fixture, and is composed of an erected leg 24a and an L-shaped portion 24b formed at the tip thereof. A bent portion 24c is formed at the tip of the L-shaped portion 24b.
The elastic piece 23 is composed of a curved elastic plate, and is fixed to the main body 20a of the fixture with a rivet material r. The elastic piece 23 is urged toward the L-shaped portion 24 b of the hook 24.

  In the illustrated example, the second fixture 30 has the same configuration as that of the first fixture 20, and therefore, the same reference numerals are given and description thereof is omitted.

<< Cosmetic material piece: Fig. 3 >>
FIG. 3 shows a cross section of the first decorative material piece 60 and the second decorative material piece 70. In the illustrated example, both have the same cross-sectional shape, but for the sake of convenience of explanation, they are distinguished from “first decorative material piece 60” and “second decorative material piece 70”. When the two decorative material pieces 60 and 70 are overlapped, one cylindrical decorative material is formed.

The first decorative material piece 60 is a semicircular arc-shaped member extending over an angular range having a central angle of approximately 180 °, and has a decorative surface such as a painted surface on the outer periphery. The first decorative material piece 60 is preferably an extrusion-molded body made of a cement-based material having a specific gravity of about 0.7 to 1.5, and has the same cross-sectional shape over the entire length.
In the recess 65 formed in the vicinity of the one side 61 of the inner peripheral surface, the elastic support protrusion 21a of the first fixture 20 is fitted here so that the first decorative material 60 is rotatably supported.

  A recess 66 is formed in the vicinity of the other side 62 of the inner peripheral surface. The recess 66 receives the L-shaped portion of the hook formed on the fixture in the decorative material attaching step. The recess 66 includes a hooking groove 66a extending in a direction substantially perpendicular to the depth direction. Its function will be described later.

In the illustrated example, the second decorative material piece 70 has the same configuration as that of the first decorative material piece 60, and therefore, the same reference numerals are given and description thereof is omitted.
Next, a procedure for attaching the decorative material will be described.

<< Attachment of First Cosmetic Material Piece 60: FIG. 4 >>
First, the decorative material fixing base 40 is attached around the column core material 10. As already described, the decorative material fixing base 40 includes the first fixture 20 and the second fixture 30.
The elastic support protrusion 21a of the first fixture 20 is engaged in the recess 65 of the first decorative material piece 60, and the first decorative material piece 60 is rotatably supported. Fig.4 (a) has shown the state just before engaging.

  The first decorative piece 60 is rotated in the direction of arrow A, and the L-shaped portion 34 b of the second fixture 30 is inserted into the recess 66. FIG.4 (b) has shown the state immediately after insertion. At this time, the elastic piece 33 of the second fixture 30 is pressed upward in the drawing by the inner surface of the first decorative material piece 60 and is in a state of being compressed and deformed. When the hand to work is released, the elastic piece 33 pushes down the first decorative piece 60 in the direction of arrow B (downward).

Thereby, the folding | returning part 34c of the L-shaped part 34b front-end | tip engages with the catching groove 66a formed in the bottom part of the recessed part 66, and prevents reverse rotation of the 1st decorative material piece 60 (FIG. 4c).
In FIG. 4C, the other side 62 of the first decorative material piece 60 is sandwiched between the hook 34 and the elastic piece 33. That is, the hook 34 and the elastic piece 33 constitute the elastic clamping portion 35 (FIG. 2a).
At this time, since the elastic protrusion 21a pushes up one side 61 of the first decorative material piece 60 upward in the drawing, these elastic forces combine to firmly fix the first decorative material piece 60. To do.

<< Attachment of second decorative material piece 70: FIG. 5 >>
Since the procedure for attaching the second decorative material piece 70 is the same as that of the first decorative material piece 60, it will be briefly described.

  From the state shown in FIG. 5 (a), the elastic support protrusion 31a of the second fixture 20 is engaged in the recess 75 of the second decorative material piece 70, and is rotatably supported (FIG. 5a). The second decorative material piece 70 is rotated in the direction of the arrow A ′, and the L-shaped portion 24 b of the first fixture 20 is inserted into the recess 76 (FIG. 5 b). When the work hand is released, the elastic piece 23 pushes up the second decorative material piece 70 in the direction of arrow B ′ (upward).

As a result, the second decorative material piece 70 is also firmly fixed as in the case of the first decorative material piece 60.
That is, the folded portion 24c at the tip of the L-shaped portion engages with the hook groove 76a formed at the bottom of the recess 76, thereby preventing the second decorative material piece 70 from rotating backward (FIG. 5c). And while the other side 72 of the 2nd decorative material piece 70 will be in the state clamped by the hook 24 and the elastic piece 23, the elastic protrusion 31a shows the one side 71 of the 2nd decorative material piece 70 in figure. 5 Push down in the middle.

≪Removal of decorative piece: Fig. 6≫
In the present invention, the decorative material pieces 60 and 70 can be easily and firmly fixed as described above. Nevertheless, if removal is necessary, this can be done easily. FIG. 6 illustrates the removal process for the first decorative material piece 60.
FIG. 6A shows the first decorative piece 60 in a fixed state. When the first decorative piece 60 is pressed upward (arrow X) against the urging force of the elastic piece 33, the folded portion 34c at the tip of the L-shaped portion 34b is pulled out from the catching groove 66a (FIG. 4b).
When the first decorative material piece 60 is pulled in the arrow Y direction from this state, the first decorative material piece 60 can be easily removed because the folded portion 34c and the catching groove 66a are disengaged. Although illustration is omitted, the second decorative piece 70 can be easily removed in the same manner.

≪Meaning of right angle≫
The hooking grooves 66a and 76a formed on the bottoms of the recesses of the decorative material pieces 60 and 70 are formed so as to extend in a “substantially perpendicular direction” with respect to the depth direction of the recesses 66 and 76, respectively. Here, “substantially perpendicular direction” means the following.
Even if it is not completely right angle, the folded portions 24c and 34c at the hook end can be inserted into and removed from the catching grooves 66a and 76a in the attaching and detaching operation steps described with reference to FIGS. The object of the present invention can be achieved if the reverse rotation can be prevented at the time of separation and the reverse rotation can be allowed at the time of separation. As long as that is the case, it does not have to be perfectly right.

<< Other Embodiments >>
In the illustrated example, the decorative material pieces 60 and 70 are rotatably supported by engaging the elastic support protrusions 21a and 31a in the recesses 65 and 75 provided in the vicinity of one side. . However, in the present invention, it is sufficient that the rotation and the elastic slide can be used at the time of attaching the decorative material piece. Therefore, as a form that is specifically supported so as to be rotatable, an appropriate form other than the illustrated one is adopted. It is possible.

Also, if the two decorative material pieces 60 and 70 are of the same configuration as in the illustrated example, it is actually necessary to produce only one type of shape member, so that in terms of cost. The merit is high. However, if necessary, two types of decorative material pieces having different cross-sectional shapes may be manufactured to form the first decorative material piece 60 and the second decorative material piece 70.
The two fixtures 20 and 30 are also advantageous in terms of cost if they have the same structure as in the illustrated example, but may be configured separately if necessary.

  It is preferable to extrude the decorative material pieces 60 and 70 from a cement-based material because the decorative material pieces are less likely to warp and have high fireproof performance. However, in the present invention, other materials can be appropriately adopted as necessary.

  In the illustrated example, the two fixtures 20 and 30 constituting the decorative material fixing base 40 are physically separate. However, for example, the two attachments 20 and 30 can be made into one member by hinge-connecting them in advance. As described above, as long as there are structural portions corresponding to both fixtures, the decorative material fixing base 40 does not have to be composed of two physically separated members.
