Summary of the Invention

Problems to be Solved by the Invention

[0004] As described above, the conventional side wall sections are integrally connected in groups of 4 to 8 around the periphery of the top surface. Therefore, as shown in Figure 11, when it is necessary to miniaturize the entire structure, or when it is necessary to increase the vertical length of the side wall sections 17 so that the height adjustment range of the upper support member 15 can be increased relative to the base support member 4, the spacing B between adjacent side wall sections 17 around the periphery of the top surface 18 tends to become narrow. For example, when attaching waterproofing material from the mounting base 2 to the main body 7 of the base support member 4 to form a waterproof layer 21, or when connecting the first connecting part 14 and the first connected part 6 with bolts and nuts to connect the upper support member 15 to the base support member 4, it becomes difficult to perform the work by working closely with tools or hands on the main body 7 from the outside. Furthermore, this problem arose because, in order to increase the distance B between the side wall portions 17, the larger the canopy portion 9 and the top surface portion 18 that covers the canopy portion 9 from above became, the more easily the canopy portion 9, which extends outward from the circumferential surface of the main body portion 7, would deform due to the load from above by other objects, etc. If the canopy portion 9 and the top surface portion 18 were made smaller to prevent this, it would become more difficult to operate the main body portion 7 in close proximity.

[0005] Therefore, the object of the present invention is to resolve the above-mentioned problems and to facilitate access and operation of the main body from the outside for construction purposes. [Means for solving the problem]

[0006] The first characteristic configuration of the present invention is a base-side support member having a first fixing portion to the mounting base, and an upper-side support member having a second fixing portion that can freely fix another object to be fixed above, and a first connecting portion that connects to the lower base-side support member so as to be vertically displaceable, wherein the base-side support member has a vertical cylindrical main body portion with the first fixing portion provided at its lower end, a roof portion that closes the upper part of the main body portion integrally connected to the main body portion, and an overhang portion that extends outward from the circumferential surface of the main body portion integrally attached to the main body portion, and the upper-side support member covers the roof portion and the overhang portion from above, Furthermore, the device is provided with a top surface on which the second fixing portion is formed, and a first connecting portion is formed on a side wall portion that is integrally connected to the periphery of the top surface and hangs downward, and a first connected portion that connects to the first connecting portion is provided on the outer periphery of the canopy, wherein a pair of the side wall portions are provided facing each other at a distance from each other at the periphery of the top surface, and with the first connecting portion and the first connected portion connected to each other, an installation operation gap is formed between the pair of side wall portions that are separated from each other in the circumferential direction of the top surface, and is larger than the width of the main body portion and allows for access operation to the main body portion from the outside.

[0007] According to the first characteristic configuration of the present invention, a pair of side wall portions are provided so as to be separated from each other and facing each other around the periphery of the top surface portion, and with the first connecting portion and the first connected portion connected to each other, a construction operation gap is formed between the pair of side wall portions that are separated from each other in the circumferential direction of the top surface portion, which is larger than the width of the main body portion and allows for access to the main body portion from the outside. This makes it easier for tools, hands, etc., to approach the main body portion from the outside through the construction operation gap, and makes it easier to perform operations such as attaching waterproofing material to the main body portion from the substrate after the substrate-side support member has been installed on the substrate, or adjusting the vertical mounting height of the upper support member to the substrate-side support member to perform connection operations.

[0008] A second characteristic feature of the present invention is that ribs projecting in a direction away from the eaves portion are continuously provided vertically along the left and right side edges of each of the side wall portions.

[0009] According to the second characteristic configuration of the present invention, in addition to achieving the above-mentioned effects of the first characteristic configuration of the present invention, the strength of each side wall portion can be increased without narrowing the gap during construction, and the load of other objects fixed by the second fixing portion can be supported by each side wall portion, and transmitted from the first connecting portion to the substrate-side support member via the first connected portion to provide stable support.

[0010] A third characteristic configuration of the present invention is that a canopy hanging wall portion is provided on the outer periphery of the canopy portion, the first connecting portion is provided on the canopy hanging wall portion, a rib connecting hanging wall portion is provided that is connected above the construction operation gap, extending across the adjacent ribs of each of the pair of side wall portions, and with the upper support member lowered relative to the base support member and adjusted to the lowest fixed height, the lower end of the rib connecting hanging wall portion is set to be higher than the lower end of the canopy hanging wall portion.

[0011] According to the third characteristic configuration of the present invention, since the pair of side wall sections are connected to each other by the rib-connected hanging wall section, the pair of side wall sections are partially formed into a cylindrical shape by the ribs and the rib-connected hanging wall section, and are further reinforced. Furthermore, when the upper support member is lowered relative to the base support member and adjusted to the lowest fixed height, the lower end of the rib-connected hanging wall section is set to be higher than the lower end of the canopy hanging wall section. Therefore, even when the upper support member is lowered to the lowest position and connected to the base support member, the rib-connected hanging wall section does not obstruct access to the main body through the construction operation gap.

[0012] A fourth characteristic feature of the present invention is that the rib has a first auxiliary attachment portion formed thereon, to which other objects can be attached.

[0013] According to the fourth characteristic configuration of the present invention, the first auxiliary attachment portion provided on the rib allows for the attachment and fixing of other objects from a different direction, separate from the second fixing portion, thereby improving the versatility of the other object fixing mechanism.

[0014] A fifth characteristic feature of the present invention is that the first connecting portion is provided with elongated holes for inserting bolts along the top and bottom, The first connected portion is provided with a square hole for inserting the square root portion of the square root bolt, and an opening is provided in the square hole that can receive the square root portion and head of the square root bolt from above.

[0015] According to the fifth characteristic configuration of the present invention, when connecting the first connecting portion and the first connected portion, a bolt is inserted through the first connecting portion provided on the side wall, and a nut is temporarily screwed onto the square-rooted bolt. Then, by lowering the bolt in this state and inserting the square-rooted portion and the head into the square hole through the opening provided on the first connected portion, the bolt is inserted through the first connecting portion and the first connected portion. By simply tightening the nut, the upper support member is connected and fixed to the base support member. In other words, the connection operation can be performed without having to insert tools or hands into the narrow space inside the canopy, and the height adjustment and fixing operation of the upper support member relative to the base support member can be easily performed, improving workability.

[0016] A sixth characteristic feature of the present invention is that a retaining portion is provided in the opening to prevent the square root portion of the square root bolt, which is received in the square hole, from moving upward.

[0017] According to the sixth characteristic configuration of the present invention, when the square-head bolt is inserted into the square hole, the upward movement of the square-head portion of the square-head bolt is prevented by the retaining portion provided in the opening. Therefore, when adjusting the height of the upper support member relative to the base support member, the square-head bolt is prevented from coming out incompletely through the opening from the square hole, making the height adjustment work easier.

[0018] A seventh characteristic feature of the present invention is that a second auxiliary mounting portion is provided on the side wall portion, which can be used to securely attach other objects.

[0019] According to the seventh characteristic configuration of the present invention, other objects can be fixed at a position even lower than the top surface. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0021] Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in FIGS. 1 to 3, the other - object fixture 1 of the present invention is provided with a base - side support member 4 having a first fixing portion 3 at an installation portion to a building (an example of the mounting base 2) such as a rooftop concrete floor or a veranda on the rooftop or veranda of a building, etc., in order to fix other objects 30 such as equipment, wiring, and piping as fixed - target members. And it is provided with an upper - side support member 15 having a second fixing portion 16 capable of freely fixing the upper - side fixed - target other object 30, and a first connecting portion 14 provided so as to be vertically displaceable with respect to the lower - side base - side support member 4.

[0022] [First Embodiment] As shown in Figures 1 to 3, the base support member 4 consists of a vertical cylindrical main body 7 with a first fixing part 3 at its lower end, and a roof part 8 that closes the upper part of the main body 7, which is integrally connected to the main body 7. In addition, a canopy part 9, which is, for example, rectangular in shape in plan view, is integrally attached to the main body 7 and extends outward from the circumferential surface of the main body 7. In other words, the canopy part 9 extends laterally integrally from the roof part 8. The upper support member 15 covers the roof portion 8 and the eaves portion 9 from above and has a top surface portion 18 that is rectangular in plan view and has a second fixing portion 16 formed thereon. A first connecting portion 14 is formed on the side wall portion 17 that is integrally connected to the periphery of the top surface portion 18 and hangs down, and a first connected portion 6 that connects to the first connecting portion 14 is provided on the outer periphery of the eaves portion 9. The first connecting portion 14 is provided with elongated holes 14A for inserting bolts along the top and bottom, and the canopy hanging wall portion 10 is integrally provided on the outer circumference of the canopy portion 9, and the first connected portion 6 is provided on the canopy hanging wall portion 10.

[0023] The first connected portion 6 is provided with a square hole 5 for inserting the square root portion of the square root bolt 12, making it possible to prevent the square root bolt 12 from rotating without using tools such as a spanner or wrench. Furthermore, the diagram shows that auxiliary holes 24 for inserting bolts are provided in the canopy section 9 so that other objects 30 can be placed directly on the roof section 8 and bolted together without using the upper support section.

[0024] A pair of the aforementioned side wall portions 17 are integrally connected to two opposing sides of the top surface portion 18, which is rectangular in plan view, so as to be separated from each other and facing each other. With the first connecting portion 14 and the first connected portion 6 connected to each other, a construction operation gap W is formed between the pair of side wall portions 17 that are separated from each other in the circumferential direction of the top surface portion 18, which is larger than the width of the main body portion 7 and allows for approach operation of the main body portion 7 from the outside (Figure 2). Therefore, tools and hands can easily approach the main body 7 from the outside through the construction operation gap W, making it easier to perform operations such as attaching waterproofing material to the main body 7 from the substrate after the substrate-side support member 4 has been installed on the substrate, or adjusting the vertical mounting height of the upper support member 15 relative to the substrate-side support member 4 to connect them. In particular, by forming the pair of side wall portions 17 to be elongated vertically, and by forming the elongated bolt insertion holes 14A provided in the first connecting portion 14 to be elongated vertically, the construction work on the main body portion 7 becomes particularly easier when increasing the vertical connection and fixing adjustment range of the upper support member 15 to the base support member 4, thereby improving workability.

[0025] As shown in Figure 3, an auxiliary canopy section 20, separate from the canopy section 9, is attached to the main body section 7 below the second fixing section 16, and a waterproof layer 21 can be attached to the peripheral side wall of the main body section 7 below the auxiliary canopy section 20. Furthermore, the waterproof layer 21 may be a coating waterproofing system that forms a waterproof coating film. In addition to coating waterproofing, there is also sheet waterproofing, in which a waterproof sheet is attached to the circumferential surface of the main body 7. In the case of sheet waterproofing, although not shown in the diagram, a stainless steel band is generally wrapped around the top of the attached sheet to prevent it from slipping down, and a liquid hardening sealant is filled between the top of the waterproof sheet and the bottom surface of the auxiliary eaves 20.

[0026] The outer edge of the auxiliary canopy 20 is formed as a sloping surface that becomes lower towards the outside. This sloping surface causes rainwater falling on the auxiliary canopy 20 to flow away from the main body 7, making it less likely for the main body 7 to get wet. Furthermore, for example, when forming a waterproof layer 21 on the periphery of the main body 7 below the auxiliary canopy 20, the sloping surface formed on the outer edge of the auxiliary canopy 20 guides the tip nozzle of the cartridge used to fill the liquid sealant from below the auxiliary canopy 20 to the periphery of the main body 7, improving the reliability of the application and making it easier to ensure waterproofing at the interface between the upper end of the waterproof layer 21 and the main body 7.

[0027] [Second Embodiment] As shown in Figures 4 to 8, ribs 25 are provided along the left and right side edges of each of the side wall portions 17, extending in a direction away from the eaves portion 9, and running vertically. Therefore, if the side wall portion 17, which is made of a flat plate, is thin, for example, it may buckle under a large load from above such as another object 30, or bend and deform due to an uneven load. However, by connecting the ribs 25, such deformations can be prevented, and the strength of each side wall portion 17 can be increased without narrowing the construction operation gap W. To this end, the load of the other object 30 fixed by the second fixing portion 16 is supported by each side wall portion 17, and transmitted from the first connecting portion 14 to the base support member 4 via the first connected portion 6, enabling stable support.

[0028] A canopy hanging wall section 10 is provided on the outer periphery of the canopy section 9, and a first connecting section 6 is provided on the canopy hanging wall section 10. Furthermore, a rib-connecting hanging wall section 26 is provided that extends across adjacent ribs 25 of each of the pair of side wall sections 17, above the construction operation gap W and hanging down from the top surface section 18. With the upper support member 15 lowered relative to the base support member 4 and adjusted to the lowest fixed height (Figure 5 → Figure 6), the lower end of the rib-connecting hanging wall section 26 is set to be higher than the lower end of the canopy hanging wall section 10. Therefore, the pair of vertical ribs 25 connected to each of the pair of side wall sections 17 and the rib-connected hanging wall section 26 connected horizontally between the pair of ribs 25 work together to further prevent deformation of the side wall section 17. Moreover, even when the upper support member 15 is lowered to the lowest position relative to the base support member 4 and connected, as shown in Figure 6, the rib-connected hanging wall section 26 does not obstruct access to the main body section 7 from the outside through the construction operation gap W. Furthermore, in order to satisfy the above functions, in the shape of the rib-connected hanging wall section 26, as shown in Figures 4 to 10, a slightly slanted lower edge is formed to reinforce the connection with the rib 25, but it is sufficient that at least the majority of the intermediate section that is connected laterally between the left and right ribs 25 satisfies the above conditions. In other words, it is sufficient that the majority of the intermediate section of the rib-connected hanging wall section 26 is set to be at least above the lower end of the canopy hanging wall section 10.

[0029] Furthermore, in terms of manufacturing, the rib 25 and the rib-connected hanging wall portion 26 may each be formed from separate metal plates and then integrated with the side wall portion 17 and the top surface portion 18 by welding or the like; or the rib 25 and the rib-connected hanging wall portion 26 may be formed from a series of metal plates and then integrated with the side wall portion 17 and the top surface portion 18 by welding; or the side wall portion 17 and the rib 25 may be formed from a single metal plate, and a separate metal plate forming the rib-connected hanging wall portion 26 may be integrated with the rib 25 and the top surface portion 18 by welding or the like; or the top surface portion 18, the side wall portion 17, the rib 25 and the rib-connected hanging wall portion 26 may be integrally molded by casting or the like.

[0030] As shown in Figures 4, 5, and 8, the first connected portion 6 is provided with a square hole 5 for inserting the square root portion of the square root bolt 12, and an opening 11 is connected to the square hole 5 that can receive the square root portion 12A and the head portion 12B of the square root bolt 12 from above. Therefore, when connecting the first connecting portion 14 and the first connected portion 6, a bolt is inserted through the first connecting portion 14 provided on the side wall portion 17, and a nut 13 is temporarily screwed onto the square-root bolt 12. Then, by lowering the bolt in this state, the square-root portion 12A and the head portion 12B are inserted into the square hole 5 through the opening 11 provided on the first connected portion 6. This results in the bolt being inserted through the first connecting portion 14 and the first connected portion 6. By simply tightening the nut 13, the square-root bolt is prevented from rotating by the square hole 5, and the upper support member 15 is connected and fixed to the base support member 4. In other words, the connection operation can be performed without inserting tools or hands into the narrow space inside the canopy section 9, and the height adjustment and fixing operation of the upper support member 15 relative to the base support member 4 can be easily performed, thereby improving workability.

[0031] Furthermore, as shown in Figures 4-5 and 8, a retaining portion 27 is provided in the opening 11 to prevent the upward movement of the square root portion 12A of the square root bolt 12 that is received in the square hole 5. In other words, the retaining portion 27 is provided with protrusions that bulge inward from the left and right sides at the opening 11 at the upper end of the square hole 5, and the distance between the left and right protrusions is slightly larger than the width of the square root portion 12A, allowing the square root portion 12A to enter the square hole 5 from above, while making it easier for the square root portion 12A of the square root bolt 12 to catch against any upward movement of the square root bolt 12. Therefore, when the upper support member 15 is lifted upward to adjust the vertical height relative to the base support member 4, the square root bolt 12 is formed in such a way that it is prevented from slipping out of the opening 11 upward.

[0032] [Another embodiment] Other embodiments are described below. In addition, in the following other embodiments, the same reference numerals are used for components similar to those in the above embodiments. <1> The main body portion 7 may be in a shape other than a cylindrical shape, such as a rectangular tube or other polygonal tube. <2> As shown in Figure 9, although the main body 7 is rectangular in shape, if each of its four sides is formed to intersect rather than be parallel to the side walls 17, then when inserting tools or hands through the construction gap W between the pair of side walls 17 to perform waterproofing work, tools or hands can be easily brought close to the main body 7 from any angle, further improving work efficiency. <3> The canopy portion 9 does not necessarily have to be integrally extended laterally from the roof portion 8, but may be positioned at a different vertical location from the roof portion 8 and extend outward from the circumferential surface of the main body portion 7. <4> The roof section 8 and the eaves section 9, as well as the top surface section 18 that covers the roof section 8 from above, may be formed in a polygon other than a rectangle or in a circular shape when viewed from above. In this case, if the top surface section 18 is circular and the pair of side wall sections 17 are partially cylindrical, these partially cylindrical side wall sections 17 will be more reinforcing than a flat plate even without the ribs 25, and the space between the pair of side wall sections 17 will form a construction operation gap W that is larger than the width of the main body section 7. <5> In addition to using a square-head bolt 12 and a nut 13 to connect the first connecting part 14 and the first connected part 6, a general bolt and nut may also be used for connection. <6> The rib 25 may be provided with a bolt insertion hole 32, as shown in Figure 10, and may be formed as a first auxiliary mounting portion 33 to which other objects 30 such as channel material can be attached. <7> As shown in Figures 12 to 15, a second auxiliary mounting portion 35 may be formed on a bracket that protrudes laterally from the side wall portion 17, so that other metal objects 30 such as channel material or square material can be attached. In this case, for example, a solar panel 36 can be attached to the other object 30, so that the solar panel installation height can be set to a lower position. Furthermore, by adjusting the vertical fixing height of the upper support member 15 relative to the base support member 4, and by adjusting the fixing angle of the top surface 18, the installation angle of the solar panel 36 can be freely adjusted. In Figure 12, the other object 30 is a rectangular tubular member, and both ends of it are provided with notches 38 for fitting into the second auxiliary mounting portion 35 from above and connecting with bolts. Alternatively, the above-mentioned other object 30 may be formed from a channel material with a U-shaped cross-section and grooves along its longitudinal direction, with the grooves of the U-shaped channel material positioned on the lower side, and both ends of the channel material fitted and connected to the second auxiliary mounting portion 35. Furthermore, 37 in the figure indicates a metal latching and fixing member for securing the solar panel 36 to another object 30.

[0033] As mentioned above, reference numerals have been used to facilitate comparison with the drawings, but this does not mean that the present invention is limited to the configuration shown in the attached drawings. Furthermore, it goes without saying that the present invention can be implemented in various forms without departing from the spirit of the invention. [Explanation of Symbols]
