Description

[Technical field]

[0001] This invention relates to a fixing structure between a steel square base column erected in the ground and an aluminum cover that is erected and fixed to this steel square base column. [Background technology]

[0002] As is well known, when constructing a gatepost or the like at the entrance of a building, a protruding aluminum cover is attached to a steel base pillar with a rectangular shape erected on the ground to improve its appearance. The simplest construction in this case is a structure shown in Fig. 7 in which a slightly larger aluminum cover 100 of similar shape is placed over the top of a steel square base pillar 1 and fastened and fixed with a bolt 5 and nut 5a that penetrate the center of the member. There is also a structure shown in Fig. 8 in which a spacer 6 is fixed so as to be located between the steel square base pillar 1 and the aluminum cover 100 at the bolt connection part of the above structure. However, in the former case, when the bolt 5 is fastened with the nut 5a, the aluminum cover 100 is deformed, and there is a drawback that it is dependent on the erection of the steel square base pillar 1 or a clearance occurs between the steel square base pillar 1 and the aluminum cover 100, causing rattling and weakening the strength. Furthermore, in the latter case, by attaching the spacer 6 to the steel square base column 1, there is little clearance, making it difficult to set up the steel square base column 1, and therefore construction is difficult and dependent on the erection of the steel square base column 1, which is a disadvantage.

[0003] In order to correct such a drawback, the prior art of Patent Document 1 discloses a column cover mounting structure in which a column cover that covers the periphery of a steel square foundation column is divided vertically into two column cover halves, and both ends of the column cover halves are fixed by fasteners such as mounting brackets. In addition, the prior art of Patent Document 2 discloses a structure in which a decorative column cover that surrounds a structural column made of a square steel pipe column is composed of a pair of opposing column cover halves with a U-shaped cross section, a cover mounting base material is attached to two opposing surfaces of the surface of the structural column, a meshing joint is formed at each divided part of both column cover halves, and a fastener that penetrates the meshing joint is screwed into the cover mounting base material to fix the column cover halves. An intermediate leg piece is provided on the inner surface of the column cover halves to be aligned with the steel square foundation column. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2003-97038 A [Patent Document 2] Japanese Patent Application Publication No. 7-292950 Summary of the Invention [Problem to be solved by the invention]

[0005] However, according to the above-mentioned Patent Document 1, the column cover is made by dividing the outer periphery of a steel square foundation column into two parts vertically, and each end of the column cover is connected and fixed to the mounting bracket attached to the steel square foundation column by screws to set up the column, so although it has a decorative effect on the steel square foundation column, the mounting bracket is weak in strength, so there is a problem that it is not possible to fix heavy structural members or exterior wall materials to the column cover. Similarly, in Patent Document 2, the decorative cover divided into two parts is attached to the steel square foundation column by fixing the overlapping parts where the edges of the divided decorative covers mesh with each other to the cover mounting base material fixed to the outer surface of the steel square foundation column with fixing devices, and the other two sides are simply abutted against the outer periphery of the steel square foundation column with intermediate leg pieces or fixed with fixing devices in the same way, so there is a problem that the fixing strength is weak and it is difficult to set up the column. Furthermore, the prior art described in these two patent documents relates to the mounting structure of a decorative cover designed to make the appearance of a steel square base column look beautiful, and is not designed to accommodate other building materials that will be fixed to the decorative cover itself and bear loads. As a result, the mounting strength is not taken into consideration, and there is a problem in that the applications are limited. [Means for solving the problem]

[0006] The present invention has been made in view of the above circumstances. To the steel square base column in order to set up the aluminum cover material surrounding the steel square base column A fixing structure for an aluminum cover material, The aluminum cover material is rectangular and slightly larger than the outer shape of the steel rectangular base pillar. If we assume that the aluminum cover material is divided into two in the center along the longitudinal direction, the cross section formed will be the long piece and the Long piece The two short pieces of aluminum covers are bent at right angles from both ends in the same direction, forming a roughly U-shaped half-aluminum cover, and the steel square base pillar is OppositeThe structure for fixing the aluminum cover material to the steel square base column in order to determine the position of the aluminum cover material surrounding the steel square base column comprises: bolts that pass through the steel square base column and the long pieces and tighten and fix the steel square base column and the long pieces at multiple points in the vertical direction of the steel square base column, by placing the two semi-aluminum covers on the side where the short pieces are to be fitted so that the divided edges of the short pieces are in close contact with each other; and adjustment screws that screw into the short and long pieces of each of the two semi-aluminum covers and have their tips protruding toward the outer periphery of the steel square base column to adjust the clearance between the outer periphery of the four steel square base columns and the short and long pieces. Also, between the outer surface of the steel square base column and the inner surface of the long piece of the semi-aluminum cover 、 The bolt To penetration Will be The advantage is that a spacer is inserted. Furthermore, a short piece of the semi-aluminum cover or an attachment piece is provided by extending the short piece. Further, a construction member is fixed to the short piece or the mounting piece. The construction member is a frame to which an exterior wall panel material is attached. Effect of the Invention

[0007] According to the invention described above, the four outer peripheries of the steel square foundation column are surrounded by two half aluminum covers, and the steel square foundation column is sandwiched between the two half aluminum covers with the long sides facing each other in the middle and fastened with bolts, so that the steel square foundation column and the two half aluminum covers are firmly connected. Meanwhile, since adjustment screws are provided at multiple locations on the vertical direction of one long side and two short sides of the two half aluminum covers, the clearance between the four outer faces of the steel square foundation column and the long and short sides of the two half aluminum covers can be changed by rotating these adjustment screws forward and backward, so that even if the steel square foundation column does not have a standing position, the aluminum cover material can be set to a standing position. Moreover, since adjustment screws are provided at multiple locations on the vertical direction of each long side and short side, more detailed adjustment of the standing position can be performed. After the aluminum cover material is set in place by adjusting the adjustment screws, the bolts are tightened with nuts to firmly connect them, completing the fixing structure of the aluminum cover material to the steel square base column, so the entire work is simple.

[0008] By interposing a spacer through which the bolt passes between the outer surface of the steel square base column and the inner surface of the long piece of the semi-aluminum cover, a clearance can be secured between the outer surface of the steel square base column and the inner surface of the long piece of the semi-aluminum cover, which increases the range of adjustment for the erection and allows the aluminum cover material to be erected even if the inclination angle of the steel square base column is large.

[0009] When a short piece of the semi-aluminum cover or an attachment piece is provided by extending the short piece, the short side or attachment piece is erected and perpendicular to the ground, so that the appearance is not marred even if decorative objects, structural members, etc. are connected and fixed to it.

[0010] When the structural member is a frame to which an exterior wall panel material is attached, the exterior wall panel can be easily installed vertically even when the steel square base columns are not yet erected. [Brief description of the drawings]

[0012] The fixing structure of the square steel foundation column and the aluminum cover material of this invention will be described with reference to Figures 1 to 6. The square steel foundation column 1 is a hollow steel column with a square cross section, and is a structural member used to fix decorative objects and structural members to the ground. It must be constructed perpendicular to the ground, that is, it must be set up. However, in reality, the set-up is often not set up during the construction process, so that the steel square foundation column 1 can be set up without having to be re-erected. Therefore, the aluminum cover material 2, which is the cover material surrounding the steel square foundation column 1, is set up so that it can be decorated and serve as a structural member.

[0013] As shown in FIG. 1, the aboveground part of a steel square base column 1, the lower end of which is fixed to the ground by concrete, has two semi-aluminum covers 3 with a roughly U-shaped cross section, which are the same as a cylindrical square column slightly larger than the outer shape of the steel square base column 1 divided vertically in the center. This division may be divided into two parts off-center. The semi-aluminum cover 3 has a long side 31 that covers the two opposing outer peripheral surfaces of the steel square base column 1, and two short pieces 32 that are bent at right angles at both ends in the same direction to face the other two outer peripheral surfaces adjacent to the two outer peripheral surfaces. Furthermore, on the extension of the short piece 32 of the semi-aluminum cover 3, an attachment piece 33 having the same length as or slightly shorter than the short piece 32 is provided as necessary, but the length of the attachment piece 33 is not limited. Also, it may be fixed at any angle to the short side 32, and other members can be attached and fixed to the mounting pieces 33 provided in this way in the same way as the short sides 32, so that the attached structural members can be supported. The length of the long side 31 is approximately the same as the length of the square steel base column 1, so that the square steel base column 1 can be inserted between the short pieces 32 on both ends of the long side 31. The long sides 31, short sides 32 and mounting pieces 33 provide the semi-aluminum cover 3 with high bending strength in the vertical direction.

[0014] As can be seen from Figs. 1 to 3, the semi-aluminum cover 3 is used by covering and fixing it from both opposing sides of the steel square foundation column 1. The semi-aluminum cover 3 is fixed to the steel square foundation column 1 by fastening the bolt 5 inserted from the bolt hole 4 of one long side 31 to the bolt hole 4 formed in advance in the steel square foundation column 1 at the center position of the opposing long sides 31 and by fastening it with a nut 5a to the screw protruding from the other long side 31. The fastening positions by these bolts 5 are provided with bolt holes 4 in the vertical direction of the steel square foundation column 1 and the semi-aluminum cover 3 at multiple positions, preferably three positions at the top, middle and bottom positions. It is preferable to provide a clearance for easy erection adjustment by interposing a spacer 6 between the outer peripheral surface of the steel square foundation column 1 and the inner surface of the long side 31 of the semi-aluminum cover 3. As a result, the edges of the two semi-aluminum covers 3 are tightly attached to each other in the center of the opposing outer surfaces of the steel square base column 1, so that the entire outer periphery of the steel square base column 1 is covered by the aluminum cover material 2.

[0015] As shown in Fig. 1, slightly above the fixing position of the bolt 5 on the long side 31 to the steel square base column 1, an adjustment screw 7 consisting of a small screw or the like is screwed and fixed to each of the long side 31 and short side 32 of each semi-aluminum cover 3 with its tip facing the outer circumferential surface of the steel square base column 1. By loosening or tightening this adjustment screw 7, the gap distance between the outer circumferential surface of the steel square base column 1 and the inner surface of the long side 31 and short side 32 of the adjustment screw 7 can be freely adjusted at six points around the circumference. The mounting position of the adjustment screw 7 is not particularly limited, but it is preferable to adjust it at the center position in the width direction of the long piece 31 and the short piece 32, and at three points at the top, middle and bottom in the vertical direction of the steel square base column 1 at the same height position around the circumference. In this way, the adjustment screws 7 are loosened from all four sides of the steel square base column 1 at six points around the circumference and three points at the top, middle, and bottom, for a total of 18 points, to adjust the unevenness and stop the rattling. This allows the erection to be adjusted, improving accuracy. However, the number of points is not limited to three in the vertical direction, and the setting can be changed depending on the required erection accuracy. When adjusting the clearance by loosening and tightening the adjustment screws 7, the bolts 5 are loosened from the nuts 5a, and the half aluminum cover 3 is placed so that it can move freely away from the outer circumferential surface of the steel square base column 1, and the aluminum cover material 2 consisting of the two half aluminum covers 3 is confirmed to be erected, before the nuts 5a are tightened.

[0016] Next, as described above, even if a steel square foundation post 1 does not have a protruding surface, an aluminum cover material 2 consisting of two semi-aluminum covers 3 is attached to its outer periphery so that it has a protruding surface. A specific example of this construction will be described with reference to Figures 4 to 6. The figures show an example of construction when constructing a gate post 10 shown in Figure 6 at the entrance of a house. The specific embodiment of the gate post 10 has an opening 11 for installing a delivery box at the upper left, and a wall member 12 with a tile pattern or the like is provided as a surface member. A total of three steel square foundation posts 1 are erected on both ends and in the center of the interior of the gate post 10, with their lower ends hardened with concrete on the ground as a skeleton. As shown in Figure 5, this gate post 10 has a unit end 13 and one end of an intermediate unit 14 connected to the left-most steel square base post 1, and similarly, the other end of the intermediate unit 14 and one end of a second intermediate unit 17 connected to the middle steel square base post 1, and the other end of the second intermediate unit 17 and another second unit end 18 connected to the right-most steel square base post 1.

[0017] 4 shows in perspective view the joint between one end of an intermediate unit 14 having an opening 11 for attaching a delivery box, which is connected and fixed to a long and slender unit end 13 on one end side via a steel square base post 1 on the left end. The unit end 13 and intermediate unit 14 are arranged in pairs with the short sides 32 of the semi-aluminum covers 3 facing each other at the joint end sides via the steel square base post 1, and the steel square base post 1 is stored between these opposing short sides 32. The frame body 15 of the unit end 13 and the frame body 16 of the intermediate unit 14 are fixed to the mounting pieces 33 of the semi-aluminum covers 3 so that they abut facing each other, and are further fitted and fixed so as to sandwich the semi-aluminum cover 3. The frame body 15 is located on the side recessed from the short side 32 on the unit end 13 side, and the frame body 16 is located on the side protruding from the short side 32 on the intermediate unit 14 side, so that when the two semi-aluminum covers 3 sandwich the steel square base post 1 from both opposing sides to cover the outer periphery, the frame bodies 15 and 16 fit together and are joined, and at this time the steel square base post 1 is hidden inside the frame bodies 14, 15 and cannot be seen from the outside. For the above reasons, in this embodiment, the semi-aluminum cover 3 is not for decoration but serves as a structural material for the gate post 10.

[0018] Next, as shown in Fig. 4, insert the bolt 5 from the bolt hole 4 on the long side 31 of the half aluminum unit 3 between the frame 15 on the unit end 13 side until it penetrates the steel rectangular base column 1 and the bolt hole 4 on the long side 31 of the other paired half aluminum cover 3, and then loosely temporarily fasten it with the nut 5a. Similarly, insert the bolt 5 into each of the remaining two overlapping bolt holes 4 in the middle and lower parts and loosely temporarily fasten them with the nut 5a. Then, set up the two half aluminum covers 3, and tighten and fix the two adjustment screws 7 located above the inlet and outlet of the long side 31 of the bolt 5, and the four adjustment screws 7 on the short sides 32 at the same height. In this way, tighten and fix the six adjustment screws 7 at approximately the same height, and then tighten and fix the adjustment screws 7 at other height positions sequentially or in parallel, and when all adjustments are completed and the set up is achieved, tighten the bolt 5 with the nut 5a to complete the installation. At this stage, if the aluminum cover material 2 still does not have a proper plumbing, adjustments can be made by partially loosening the adjustment screws 7 and nuts 5a.

[0019] When the unit end 13 and the intermediate unit 14 are fixed in a standing state on both sides of the left-end steel square foundation column 1, the opposite end of the intermediate unit 14 and the second steel square foundation column 1 in the center are then set up and connected and fixed. At this time, the opposite end of the intermediate unit 14 and one end of the other second intermediate unit 17 are connected and fixed by sandwiching the steel square foundation column 1. In this case, the second intermediate unit 17 is lifted and inserted from above between the center and right-end steel square foundation columns 1, and then connected and fixed to the intermediate unit 14 by sandwiching the center steel square foundation column 1. Then, the other second unit end 18 is connected and fixed by sandwiching the right-end steel square foundation column 1. The connection and fixation by sandwiching these steel square foundation columns 1 can be performed simply by adjusting the standing using the respective adjustment screws 7, bolts 5, and nuts 5a, as described above. As a final step, a top plate member 219 is fixed to the top of the frames 15 and 16 to seal the top surface of the gatepost 10.

[0020] As a result, even when all three square steel foundation columns 1 are not yet erected, the aluminum covering material 2 consisting of the two half aluminum covers 3 sandwiching the square steel foundation columns 1 is erected. Moreover, the short pieces 32 and mounting pieces 33, which are parts of the aluminum covering material 2 that are protruding, and the wall members 12 such as wall panels that are connected and fixed to the frames 15, 16 fixed to these, also protrude, making the building look good to the eye as if it were a straight-constructed structure. Moreover, since the aluminum covering material 2 is firmly fixed to the square steel foundation columns 1 with the bolts 5 and nuts 5a, it can withstand strong winds and impacts.

[0021] In the above embodiment, a hollow steel rectangular base column is used as the base column, but a cylindrical steel base column or a polygonal base column may be used instead. In the case of these shapes, a hollow tube of a similar shape slightly larger than the base column is divided vertically into two, and the cover material can be exposed by the same means. In this embodiment, the exposed aluminum cover material 1 is surrounded and hidden by the wall member 12, which is a structural finishing member, but when used simply as a decoration, the exposed aluminum cover material 2 can be effectively used by applying decoration to it. Furthermore, in this embodiment, an example has been described in which aluminum, which is a metal that is lightweight, easy to process, and has an appropriate hardness, is used as the cover material, but metals such as copper, brass, and stainless steel may also be used. Furthermore, when used simply for decoration, a synthetic resin material can also be used. [Industrial Applicability]

[0022] This invention covers the outer periphery of the foundation pillar that does not have a raised surface, and the covering material is made to project the raised surface, and the covering material is made to be able to withstand a load, so it can be applied not only to gate pillars but also to various types of exterior structures of many buildings. Therefore, it has a wide range of applications and is expected to be used as a new construction method in the building and construction industries. [Explanation of symbols]
