Abstract
Description
Technical Field
[0001] The present invention relates to a suspension reinforcement member for reinforcing a suspension piece for a suspension base for suspending air conditioning equipment or the like from ceiling members such as slabs and cross beams.
Background Art
[0002] Conventionally, for example, as shown in FIG. 17, when suspending a pipe 100 from a beam 101 which is a ceiling member, the upper end of a plate-shaped suspension piece 102 is welded to the lower surface of a flange 101a of the beam 101, and the upper ends of vertical channel steels 103a, 103a of a suspension base 103 are bolted to this suspension piece 102. Then, the pipe 100 is attached to this suspension base 103.
[0003] In this way, the pipe 100 and air conditioning equipment are suspended from a beam 101 or a slab which is a ceiling member using the suspension base 103.
[0004] By the way, there are cases where the suspension base 103 sways due to an earthquake or the like. The suspension piece 102 made of SS steel plate is strong against swaying in the direction parallel to its surface, but is vulnerable to swaying in the A - A direction orthogonal to the surface.
[0005] Therefore, attempts have been made to overcome the vulnerability in the above direction by making the suspension base 103 box-shaped and incorporating braces obliquely therein, or by connecting the space between adjacent beams with steel materials or the like and attaching braces or turnbuckles thereto.

Embodiments for Carrying Out the Invention
[0014] With reference to the drawings, embodiments of the present invention will be described in detail below.
[0015] The suspension point reinforcement member according to this embodiment is a suspension point reinforcement fitting as shown in Fig. 1, which reinforces the suspension point piece used for the suspension bracket for suspending equipment such as pipes and air conditioning equipment to be targeted from the ceiling members of slabs and beams. Note that, as an example of the suspension point reinforcement member of the present invention, a suspension point reinforcement fitting is taken up, but other materials are also possible.
[0016] That is, this suspension point piece 102 is a plate-shaped member and is a member for attaching the main body of the suspension bracket 103 to the ceiling member as in the prior art.
[0017] The suspension point reinforcement fitting 10 of this embodiment includes a vertical plate portion 1 in the vertical direction and a horizontal plate portion 2 in the horizontal direction, and the lower surface 2a of the horizontal plate portion 2 is fixed at a first predetermined angle α with respect to one surface 1a1 of the upper portion 1a of the vertical plate portion 1.
[0018] The first predetermined angle may be a right angle, an acute angle, or an obtuse angle. Here, the angle formed between surfaces means the angle formed between two perpendicular lines drawn from a point on the intersection line where the surfaces intersect to one surface and then to the other surface.
[0019] Furthermore, a reinforcing plate portion 3 is disposed between one surface 1a1 of the vertical plate portion 1 and the lower surface 2a of the horizontal plate portion 2, is orthogonal to one surface 1a1 of the vertical plate portion 1, and is fixed at a second predetermined angle β with respect to the lower surface 2a of the horizontal plate portion 2. The second predetermined angle β may also be a right angle, an acute angle, or an obtuse angle.
[0020] Also, the other surface 1a2 of the vertical plate portion 1 is attached to one surface 102a of the suspension point piece 102, and the upper surface 2b of the horizontal plate portion 2 is attached to the ceiling member 4. Therefore, the inclination of the upper surface 2b of the horizontal plate portion 2 will be arranged along the inclination of the ceiling member 4.
[0021] With such a suspension point reinforcement fitting 10, even if the suspension point piece 102 is shaken in the direction A-A orthogonal to its surfaces 102a and 102b, since the reinforcing plate portion 3 is attached to the suspension point piece 102 through the vertical plate portion 1 so as to be orthogonal to the suspension point piece 102, the shaking can be significantly suppressed.
[0022] Furthermore, as shown in FIG. 2, this suspension point reinforcement fitting 10 can also be attached to the other surface 102b of the suspension point piece 102. In this way, by attaching this suspension point reinforcement fitting 10 to both sides of the suspension point piece 102, it becomes even more robust against shaking.
[0023] FIG. 3 is a specific example of FIG. 2. As the beam 101 as the ceiling member 4, channel steels connected back to back are used, and the upper end of the suspension point piece 102 is sandwiched and fixed in the gap therebetween.
[0024] Such a suspension point piece 102 and the flange 101a of the beam 101 are fixed with the suspension point reinforcement fitting 10 by bolts. That is, the vertical channel steels 103a and 103b of the suspension base 103 are arranged on both surfaces 102a and 102b of the suspension point piece 102, and further, the vertical plate portions 1 and 1 of the suspension point reinforcement fittings 10 and 10 are arranged outside the channel steels 103a and 103b, and they are tightened together with four bolts respectively. Also, the horizontal plate portions 2 and 2 are fixed to the flange 101a with two bolts respectively. By tightening together in this way, not only the shaking of the suspension point piece 102 can be prevented, but also the shaking of the vertical channel steels of the suspension base 103 can be surely suppressed.
[0025] FIG. 4 shows an example in the case where the suspension base 103 has three vertical channel steels 103a, 103a, and 103a, and it shows the case of the flange 101a of an inclined beam 101 that is not horizontal as the ceiling member 4 to which it is suspended. Even in such a case, the suspension point reinforcement fittings 10, 10, and 10 of this embodiment suppress the shaking in the orthogonal direction A-A of the respective suspension point pieces 102, 102, and 102.
[0026] Figs. 5 to 10 are partial enlarged views of Fig. 4, showing the case where the suspension reinforcement fitting 10 of this embodiment is attached to both sides of the suspension piece 102 on the flange 101a of the inclined beam 101 instead of the horizontal one. Fig. 5 is the front view thereof, Fig. 6 is the rear view, Fig. 7 is the right side view, Fig. 8 is the plan view, Fig. 9 is the perspective view seen from above on the right, and Fig. 10 is the perspective view seen from behind.
[0027] Figs. 11 to 16 are different from Figs. 5 to 10 in that the ceiling member 4 is the slab 104 instead of the beam 101, and the others are the same.
[0028] That is, it shows the case where the suspension reinforcement fitting 10 of this embodiment is attached to both sides of the suspension piece 102 on the inclined slab 104 instead of the horizontal one. Fig. 11 is the front view thereof, Fig. 12 is the rear view, Fig. 13 is the right side view, Fig. 14 is the plan view, Fig. 15 is the perspective view looking up from the right, and Fig. 16 is the perspective view looking up from behind.
[0029] Thus, the suspension reinforcement member (fitting 10) of the present invention is applicable regardless of the type of the ceiling member 4 and regardless of the presence or absence of the inclination of the ceiling member 4.
