In decorative columns like those in Patent Document 1, the intermediate member is fixed to only one side of the column body and is fixed with screws, which means that the attachment strength between the intermediate member and the column body is easily weakened. In addition, one end of the half that is divided from the cylinder is fixed to the intermediate member and joined to the column body, and the other end is joined to the other half, and since each half needs to be joined, construction work is time-consuming.

Therefore, the present invention aims to provide a mounting bracket, a pillar structure, and a method for renovating a pillar that can securely and easily fix a pillar decorative material to the pillar body.

The mounting bracket of the present invention is a mounting bracket that fixes a column decorative material formed into a cylindrical shape by combining two semi-cylindrical materials formed into a semi-cylindrical shape on a square tubular column main body, and has a mountain-shaped base that is fixed to the two side surfaces that form the corners of the column main body, a fixing part formed by bending one end of the base at a right angle and screwing the semi-cylindrical material to the tip, and a locking part formed by bending the other end of the base at a right angle and abutting the inner surface of the semi-cylindrical material, and has an overall shape that is approximately W-shaped when viewed from above, and the two mounting brackets are fixed at their respective bases to the two diagonal corners of the column main body, holding the two semi-cylindrical materials and fixing the column decorative material to the column main body.

The column structure of the present invention is a column structure in which a column decorative material is fixed to a column main body, and is characterized by comprising the column main body having a square tube shape, the column decorative material provided on the outer periphery of the column main body and formed into a cylindrical shape by combining two semi-cylindrical materials, and the two mounting brackets described above fixed to the diagonal corners of the column main body.

The column structure of the present invention is characterized in that the two semi-cylindrical materials overlap each other at both ends to form a cylindrical shape, and the mounting bracket is secured to the overlapping portion of the two semi-cylindrical materials of the fixing portion with a screw, and the locking portion abuts the circumferential middle portion of the semi-cylindrical material.

The column structure of the present invention is characterized in that the overlapping end portions of the two semi-cylindrical materials are positioned radially inward from the outer periphery of the semi-cylindrical materials, and the bottom surfaces of the end portions are formed into a groove shape that overlaps with each other.

The method for reforming a column of the present invention is a method for reforming a column to construct a column structure according to any one of claims 2 to 4 by fixing the newly installed column decorative material to the outer periphery of the existing column body, and is characterized by comprising the steps of fixing the base of the mounting bracket to each of the two diagonal corners of the column body, arranging the two semi-cylindrical materials so that their inner surfaces abut the tips of the engagement parts of the mounting brackets, and screwing the overlapping side end parts of the two semi-cylindrical materials to the fixing parts of the mounting brackets.

The pillar reform method of the present invention is characterized in that the pillar body has a square cross section, and mounting brackets of different dimensions are used depending on the dimensions of the pillar body.

The mounting bracket of the present invention has a base formed in a mountain shape that is fixed to each of the two side surfaces that form the corners of the column body, so the mounting bracket can be easily positioned at the mounting position, and the mounting bracket can be easily and firmly fixed. The mounting bracket has a locking portion that abuts against the inner surface of the semi-cylindrical material, and the semi-cylindrical material is screwed to the fixing portion, so the semi-cylindrical material can be easily fixed to the mounting bracket, and the construction work of fixing the column decorative material to the column body can be simplified.

According to the pillar structure of the present invention, the pillar decorative material is fixed to the pillar body using the above-mentioned mounting bracket, which makes the construction work easier.

According to the column structure of the present invention, the overlapping side ends of the two semi-cylindrical materials are screwed to the fixing parts of the mounting brackets, so that the side ends of the two semi-cylindrical materials can be fixed with a single screw, reducing the amount of work required for construction. In addition, each semi-cylindrical material can be more firmly fixed to the column body by screwing both side ends to the fixing parts and abutting the inner surface of the middle part to the locking part.

According to the column structure of the present invention, the two end portions that overlap each other and are screwed to the fixing parts of the mounting bracket are positioned radially inward from the outer periphery of the semi-cylindrical material, and the bottom surfaces of the two end portions are formed in a groove shape where they overlap, so they overlap and are screwed at a position recessed from the outer periphery of the column decorative material, preventing a loss of design.

The method for remodeling a column of the present invention includes the steps of fixing the base of the mounting bracket to each of two diagonal corners of the column body, arranging two semi-cylindrical materials so that their inner surfaces abut the tips of the locking parts of the mounting brackets, and screwing the overlapping side ends of the two semi-cylindrical materials to the fixing parts of the mounting brackets, which makes it easy to carry out the construction work of fixing the column decorative material to the column body.

According to the pillar renovation method of the present invention, the pillar body has a square cross section, and mounting hardware of different dimensions is used depending on the dimensions of the pillar body. Therefore, even if the cross-sectional dimensions of an existing pillar body are different, the pillar can be renovated using the same pillar decorative material by changing the mounting hardware.

Below, an embodiment of the mounting bracket 1, the column structure 2, and the column remodeling method according to the present invention will be described with reference to the drawings. The column structure 2 is an outdoor column structure erected between the outdoor floor surface 3 and the eaves back surface 4 of, for example, an entrance porch, and is formed by fixing a cylindrical column decorative material 6 to a square tubular column main body 5. The location where the column structure 2 is erected is not limited to the entrance porch, but can be erected in a space where an outdoor floor surface 3 is provided and a structure formed to extend upward from the building is provided, such as under a balcony, under the eaves, or in a piloti.

As shown in Fig. 1, the column structure 2 comprises a square tubular column body 5, a column decorative material 6 provided on the outer periphery of the column body 5, and two mounting brackets 1 for fixing the column decorative material 6 to the column body 5. As shown in Figs. 1 and 3, the column body 5 is made of steel and has a square tubular shape with a horizontal cross section of approximately 60 mm on each side. The lower end of the column body 5 is joined to an outdoor floor surface 3 made of concrete, for example, and the upper end of the column body 5 is erected higher than the eaves back surface 4 and is fixed to a structure such as a beam or arm that constitutes a structure (not shown) that protrudes from the building and is provided above the outdoor floor surface 3, and the column body 5 supports the load of the structure protruding from the building.

As shown in Figs. 1 and 6, the column decorative material 6 is formed into a cylindrical shape by combining two semi-cylindrical materials 60, which are made of aluminum, for example. The two semi-cylindrical materials 60 are formed slightly shorter than the length from the outdoor floor surface 3 to the eaves back surface 4, and the horizontal cross-sectional shape is formed into a semicircular arc. One side end 61 of the horizontal cross-sectional shape of the semi-cylindrical material 60 is bent radially inward and further bent toward the opposing semi-cylindrical material 60 to form an L-shape. The other side end 62 of the horizontal cross-sectional shape of the semi-circular arc is bent radially inward of the semi-cylindrical material 60, further bent toward the opposing semi-cylindrical material 60, and further bent radially outward to form a groove shape. When the two semi-cylindrical materials 60 are combined around the column main body 5, the bottom surfaces of the both side ends 61 and 62 overlap each other to form a groove-shaped joint 63, forming a cylindrical column decorative material 6 as a whole. The pillar decorative material 6 is attached around the pillar body 5, with its lower end abutting the outdoor floor surface 3 and its upper end being 10 mm lower than the eaves back surface 4.

As shown in Figures 1 and 2, the two mounting brackets 1 are fixed to the diagonal corners of the column body 5. The mounting brackets 1 are formed by bending a steel plate so that the overall shape is approximately W-shaped when viewed from above, and each bending angle is approximately a right angle. The mounting bracket 1 has a mountain-shaped base 10 that is fixed in contact with two side surfaces that form the corner of the column body 5, a fixing part 11 formed by bending one end of the base 10 at a right angle and having the side ends 61, 62 of the semi-cylindrical material 60 screwed to its tip, and a locking part 12 formed by bending the other end of the base 10 at a right angle and having its tip abutting the inner circumferential surface of the semi-cylindrical material 60.

One screw insertion hole 13 is formed on one surface constituting the base 10, and two screw insertion holes 13 are formed on the other surface constituting the base 10. These three screw insertion holes 13 are formed at intervals from each other in the height direction. The base 10 is fixed to the column body 5 by driving a fixing screw 14 into each screw insertion hole 13. Since the base 10 is formed in a mountain shape bent at an approximately right angle, it can be stably abutted against the corner of the column body 5, improving the workability when driving the fixing screw 14. In addition, the fixing screw 14 is driven into two adjacent side surfaces sandwiching the corner of the column body 5 through the screw insertion holes 13 formed on each of the two surfaces of the base 10, so that the fixing screw 14 can be driven from two orthogonal directions to firmly fix the mounting bracket 1.

The fixing part 11 is bent at a right angle from one end of the base 10 to protrude radially outward from the column decorative material 6, and the tip of the fixing part 11 is further bent at a right angle to form a bent part 15, which abuts against the inner surface of one side end part 61 of the column decorative material 6. The column decorative material 6 and the fixing part 11 are joined by a joint screw 16 penetrating the overlapping side ends 61, 62 of the two semi-cylindrical materials 60 of the column decorative material 6 and the bent part 15 at the tip of the fixing part 11. In this way, by overlapping the side ends 61, 62 of the two semi-cylindrical materials 60 with each other and penetrating the joint screw 16, the side ends 61, 62 of the two semi-cylindrical materials 60 can be fixed to the fixing part 11 of the mounting hardware at the same time with one joint screw 16, which reduces the screw driving work. In addition, the side ends 61, 62 of the column decorative material 6 form a groove-shaped joint 63 whose bottom surfaces overlap each other, and the connecting screw 16 is driven into the bottom surface of the joint 63, so that the head of the connecting screw 16 is positioned inside the outer periphery of the column decorative material 6.

A joint cover material 64, whose surface exposed to the outside forms the same arc as the outer peripheral surface of the column decorative material 6, is inserted into the joint 63 formed by the side ends 61, 62 of the column decorative material 6, hiding the head of the connecting screw 16. The joint cover material 64 has the same vertical length as the column decorative material 6, and is inserted over the entire length of the joint 63 from the top to the bottom of the column decorative material 6.

The locking portion 12 is bent at a right angle from the other end of the base 10 and protrudes radially outward from the pillar decorative material 6. A protrusion 65 is formed on the inner surface of the circumferential middle part of the pillar decorative material 6 so that the side of the tip of the locking portion 12 abuts against it. The pillar decorative material 6 is positioned by the tip of the locking portion 12 abutting against its inner surface and the protrusion 65 abutting against the side of the tip of the locking portion 12.

As shown in FIG. 10, the dimensions of the mounting bracket 1 are determined so that the radius α of the inner circumference of the column decorative material 6 is equal to the sum of the protruding length β of the engaging portion 12 and half the length of one side of the horizontal cross section of the column main body 5, γ, and the distance σ from the innermost surface of the overlapping bottom surfaces of both side ends 61, 62 of the semi-cylindrical material 60 constituting the column decorative material 6 to the center of the column decorative material 6 is equal to the sum of the protruding length ε of the fixing portion 11 and half the length of one side of the horizontal cross section of the column main body 5, γ. Note that, as shown in FIG. 11, the mounting bracket 1 is available in a number of different dimensions according to the cross-sectional dimensions of the column main body 5, and the column decorative material 6 can be of the same cross-sectional dimensions regardless of the cross-sectional dimensions of the column main body 5.

As shown in Figures 6 and 12, a watertight material 66 made of elastic synthetic resin foam is placed on the upper end of the pillar decorative material 6, and serves as a base for a caulking material (not shown) that fills the gap between the eaves back surface 4 and the pillar decorative material 6. The watertight material 66 consists of two semicircular flat plates 67, each of which has a cutout on the inside that is half the cross-sectional shape of the pillar main body 5, and the two flat plates 67 are abutted against each other across the pillar main body 5 to form a circular watertight material 66. The diameter of the outer periphery of the watertight material 66 is shorter than the diameter of the inner periphery of the pillar decorative material 6, and the lower part is stored inside the pillar decorative material 6, the upper part protrudes above the upper end of the pillar decorative material 6, and the upper surface abuts against the eaves back surface 4.

The pillar renovation method improves the design of the pillar by attaching a new pillar decorative material 6 to the outer periphery of the existing pillar main body 5. In the pillar renovation method, first, as shown in Figures 3 and 4, the base 10 of the mounting bracket 1 is fixed to the corner of the existing pillar main body 5. Specifically, the base 10 of the mounting bracket 1 is pressed against two adjacent surfaces that sandwich the corner of the pillar main body 5, and screws are driven into each of the three screw insertion holes 13 formed in the base 10 to join the pillar main body 5 and the mounting bracket 1.

The mounting brackets 1 are attached to two diagonal corners of the column body 5, and three are attached at a time with a gap in the vertical direction. After the mounting brackets 1 are fixed to the column body 5, as shown in FIG. 5, two semicircular flat plates 67 forming the watertight material 66 are arranged to sandwich the upper part of the column body 5, and the watertight material 66 is attached to the upper part of the column body 5 and at the position that is the upper end of the column decorative material 6. Then, as shown in FIG. 6 and FIG. 7, the two semicylindrical materials 60 constituting the column decorative material 6 are abutted against the tips of the locking parts 12 of the mounting brackets 1 arranged diagonally to each other, and the side of the tip of the locking part 12 is arranged to abut against the protrusion 65, so that the column decorative material 6 is arranged cylindrically around the column body 5. Then, a joining screw 16 is driven through the overlapping side ends 61, 62 of the two semi-cylindrical materials 60 and the bent portion 15 formed at the tip of the fixing portion 11 of the mounting bracket 1, and the pillar decorative material 6 is fixed to the mounting bracket 1.

As shown in Figure 9, a joint cover material 64 is inserted into the two joints 63 formed by the two side ends 61, 62 of the semi-cylindrical material 60 to cover the heads of the joining screws 16 and make the outer circumference of the column decorative material 6 completely circular. After that, a caulking material (not shown) is filled between the upper end of the column decorative material 6 and the eaves back surface 4 to complete the column structure 2. At this time, the watertight material 66 protruding from the upper end of the column decorative material 6 and abutting the eaves back surface 4 functions as a backup material for the caulking material.

As described above, according to the pillar renovation method of this embodiment, the mounting bracket 1 is fixed by abutting the base 10 against the corner of the pillar body 5, which makes it easy to position the mounting bracket 1 and drive in the fixing screw 14. The pillar decorative material 6 is positioned by abutting the protrusion 65 of the semi-cylindrical material 60 against the side of the tip of the locking part 12 of the mounting bracket 1, and the overlapping side end parts 61, 62 of the two semi-cylindrical materials 60 and the fixing part 11 of the mounting bracket 1 are fixed with the connecting screw 16, which makes it easy to install the pillar decorative material 6.

It goes without saying that the embodiment of the present invention is not limited to the above-mentioned embodiment, and can be modified as appropriate without departing from the scope of the concept of the present invention.

The mounting bracket 1, the column structure 2, and the column remodeling method according to the present invention are suitable as mounting bracket 1, the column structure 2, and the column remodeling method used in remodeling to improve the design of the column body 5 that is provided between the outdoor floor surface 3 and the eaves back surface 4, such as the entrance porch of a house.
