Description

[Technical Field]

[0001] The present invention relates to a structural joint device for connecting hanging members and angle members to structural members of buildings made of H-shaped steel or the like. [Background technology]

[0002] Conventionally, steel materials such as H-shaped steel are used for the structures supporting factory ceilings, and components such as suspension members are connected to these H-shaped steel. For example, suspension members are connected to structural beams made of H-shaped steel, and various pipes, air conditioning equipment, and the like are attached to these suspension members (see Patent Document 1).

[0003] In such cases, it is necessary to later attach connecting members to the H-shaped steel beams of the building.

[0004] However, it is difficult to later weld connecting hardware or plates for hanging support to the architectural beams, etc., and it is also impossible to drill holes in the architectural beams, etc. for connecting hardware.

[0005] Furthermore, such connecting members are located at the intersections of building beams and equipment, piping, etc., and must be able to resist both vertical and horizontal forces.

[0006] Conventionally, the connecting member that meets such requirements has been to clamp the flange of the H-shaped steel beam of the building between two steel plates, one above the other, and secure it in place. In the gap equal to the thickness of the flange, several types of Ferrar plates with different thicknesses are inserted for adjustment. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.

[0021] FIG. 1 is a diagram showing a structural joint device 1 according to an embodiment of the present invention applied to an H-section steel 2, and FIGS. 3 to 15 are diagrams of the structural joint device 1 itself.

[0022] As shown in Figures 1 to 15, the structural joint device 1 comprises a U-shaped cross-section member 10 having an upper plate portion 10a, a lower plate portion 10b, and a connecting plate portion 10c connecting the upper plate portion 10a and the lower plate portion 10b, and a bolt portion 11 that is screwed into the upper plate portion 10a and has its tip 11a facing between the upper plate portion 10a and the lower plate portion 10b.

[0023] Furthermore, 12 is a mounting member that is fixed to the lower plate portion 10b, one end 12a of which faces between the upper plate portion 10a and the lower plate portion 10b, and the other end 12b of which projects outside the lower plate portion 10b, and can be connected to another member 13.

[0024] Furthermore, a rod portion 14 is provided which stands on a part of the connecting plate portion 10c and has a tip 14a which faces between the upper plate portion 10a and the lower plate portion 10b.

[0025] Furthermore, an upper surface 14a1 of the tip 14a of the rod portion 14 and an upper surface 12a1 of one end 12a of the mounting member 12 are aligned in the up-down direction.

[0026] The mounting member 12 has a nut portion 12c fixed to the inner surface 10b1 of the lower plate portion 10b, and a bolt member 12d that is screwed into the nut portion 12c, penetrates the lower plate portion 10b, and protrudes to the outside. The other member 13 is connected to the mounting member 12 by being sandwiched between a nut member 12e that is screwed onto a bolt member 12d that protrudes outward and the outer surface of the lower plate portion 10b.

[0027] The other members 13 are connected to equipment such as pipes and ducts, and hanging bolts.

[0028] To fix such a structural joint device 1 to the flange 2a of the H-shaped steel 2, as shown in Figure 1, first rotate the bolt portion 11 to position the tip 11a upward, thereby creating a large space between the upper plate portion 10a and the lower plate portion 10b.

[0029] Then, the structural joint device 1 is moved closer so that the flange 2a of the H-shaped steel 2 enters the space between the upper plate portion 10a and the lower plate portion 10b, and the underside 2a1 of the flange 2a comes into contact with and rests on the upper surface 12a1 of one end 12a of the mounting member 12. Thereafter, the tip 11a of the bolt portion 11 is lowered and pressed against the upper surface 2a2 of the flange 2a with the tip 11a, and the flange 2a is tightened so that it is firmly fixed between the underside of the tip 11a of the bolt portion 11 and the upper surface 12a1 of one end 12a of the mounting member 12.

[0030] In this way, the structural joint device 1 can be easily and effectively fixed to the flanges 2a of the H-shaped steel 2 having various thicknesses.

[0031] Furthermore, at this time, the other part of the lower surface 2a1 of the flange 2a also contacts the upper surface 14a1 of the tip 14a of the rod portion 14. This is because, as described above, the upper surface 14a1 of the tip 14a of the rod portion 14 and the upper surface 12a1 of one end 12a of the mounting member 12 are aligned in the vertical direction.

[0032] This structure generates a frictional force between the upper surface 14a1 of the tip 14a of the rod portion 14 and the lower surface 2a1 of the flange 2a, providing a structure with strong resistance to horizontal shaking. The frictional force is generated at the part indicated by the symbol F in Figure 1.

[0033] Furthermore, as shown in Figure 1, when the flange 2a of the H-shaped steel 2 is sandwiched between the U-shaped cross-section member 10, the flange 2a is sandwiched so that the side surface 2a3 of the flange 2a abuts against the inner side surface 10c1 of the connecting plate portion 10c of the U-shaped cross-section member 10 (see F'), thereby generating a frictional force there, which ultimately makes it possible to resist horizontal shaking.

[0034] Furthermore, in this case, as shown in Figure 2, by combining the two opposing rod portions 14 into a single rod portion 14' and tightly fastening the two U-shaped cross-section members 10, 10 from the left and right, the frictional force at that point can be further increased. In other words, by using a through bolt as an example of the rod portion 14 and tightly fastening it from the left and right, the frictional force can be further increased. 14a' is a nut.

[0035] Figure 16 shows another embodiment of the present invention, in which the rod portion 14 is formed by another bolt 16, which is screwed onto the connecting plate portion 10c at a predetermined angle, for example 100 degrees, inclined upward relative to the connecting plate portion 10c.

[0036] Furthermore, a plate 15 is erected inward on the connecting plate portion 10c above the bolt 16, and the tip 16a of the bolt 16 abuts against the lower surface 15b of the plate 15, making it possible to push up the plate 15. It is desirable that this plate 15 have some elasticity.

[0037] An upper surface 15a of the plate 15 and an upper surface 12a1 of one end 12a of the mounting member 12 are aligned in the up-down direction.

[0038] Therefore, even if a small gap occurs between the lower surface 2a1 of the flange 2a and the upper surface 15a of the plate 15, by rotating the bolt 16, the upper surface 15a of the plate 15 can be pushed up, ensuring frictional force and resisting horizontal shaking.

[0039] Figures 17(A) and (B) show another embodiment of the present invention, in which the rod portion 14 is formed by another bolt 20 and is screwed onto the connecting plate portion 10c at a predetermined angle, for example 100 degrees, inclined upward relative to the connecting plate portion 10c.

[0040] Furthermore, an inserted member 21, such as a nut, is loosely fitted onto the tip of this bolt 20, and a backing plate 22 is fixed to the top of the inserted member 21.

[0041] 17(B), the backing plate 22 rises obliquely upward. As a result, the upper surface of the backing plate 22 comes into contact with the lower surface 2a1 of the flange 2a (see F'').

[0042] In this way, friction is generated at the contacting portion against horizontal shaking, and resistance is achieved. Furthermore, the flange 2a can be sandwiched between the contact plate 22 and the tip 11a of the upper bolt portion 11.

[0043] Figures 18 to 23 show a state in which structural joint devices 1, 1 are attached to opposing positions of two flanges 2a, 2a of one H-shaped steel 2, and the upper flange of a channel steel 13 as another member 13 is attached to the other ends 12b, 12b of the mounting members 12, 12 of each structural joint device 1, 1 using a nut member 12e.

[0044] Figure 24 shows a state in which a total of four structural connectors 1, 1, 1, 1 are attached to two other opposing positions, a predetermined distance apart, on the two flanges 2a, 2a of the single H-shaped steel 2. A total of two other members 13, 13 are fixed to each of the opposing positions.

[0045] In Figures 25 and 26, two H-shaped steels 2, 2 are placed side by side, and four structural joints 1, 1, 1, 1 are attached to a total of four flanges 2a, 2a, 2a, 2a of each H-shaped steel 2, 2, and a total of one other member 13 is attached in a bridging state.

[0046] 27 and 28 show another channel steel 13' welded and hanging down below the channel steel 13 as another member 13, and a wire 17 curved into a circle is fixed to the channel steel 13'. A pipe 18 is passed through this circular wire 17 and suspended.

[0047] Figures 29 and 30 show the state in which the duct 19 is placed. In this case, the lower ends of the channel steels 13', 13' welded and hanging down to the channel steel 13 fixed to structural joints 1, 1 attached to two parallel H-shaped steels 2, 2 are connected by another channel steel 13'', and the duct 19 is supported by the channel steel 13''. [Industrial Applicability]

[0048] The structural joint device of the present invention is easy to use and has excellent resistance to horizontal forces, making it useful for suspending air conditioning equipment and the like from the ceiling. [Explanation of symbols]
