Description

[Technical field]

[0001] The present invention relates to a suspension stand used for suspending and installing air conditioning equipment, for example, from the ceiling of a building. [Background technology]

[0002] For example, as shown in FIG. 38, a suspension stand 102 for suspending an air conditioner 101 or the like from a ceiling 100 of a building is known. Summary of the Invention [Problem to be solved by the invention]

[0003] However, conventional suspension racks are very heavy, and the air conditioning equipment to be suspended is often also heavy.

[0004] For this reason, it has been necessary to use expensive steel materials for the suspension frame that can adequately withstand the weight.

[0005] In particular, there is a need for a mounting system that can withstand both lateral and vertical shaking.

[0006] Furthermore, while it would be desirable to have a hanging rack with the same top surface size as the air conditioning equipment to be suspended, the presence of other equipment such as pipes, ducts, and electrical cable racks near the ceiling makes it difficult to use a hanging rack with the same top surface size as the air conditioning equipment.

[0007] The present invention has been made in consideration of the problems with the conventional suspension racks described above, and has an object to provide a suspension rack that can suspend air conditioning equipment, etc., even in a location where other equipment such as piping is present. [Means for solving the problem]

The upper frame is fixed to the lower end of the vertical column member, This is a suspension stand characterized in that a suspension tool for suspending a device to be suspended is attached to the lower frame.

[0009] A second aspect of the present invention is the suspension stand according to the first aspect of the present invention, wherein the upper frame is made of stainless steel material instead of aluminum material.

[0010] The third aspect of the present invention is This is a second suspension stand of the present invention, in which an expansion reinforcement member is diagonally connected between the lower part of the vertical column member and the protruding portion of the upper frame that protrudes outward beyond the vertical column member.

[0011] The fourth invention is the suspension stand of the third invention, wherein a main body reinforcing member made of SS material is diagonally connected to the planar space formed by the adjacent vertical column members and horizontal beam members. Effect of the Invention

[0012] According to the present invention, it is possible to realize a suspension rack that does not use expensive steel materials, is resistant to lateral and vertical vibrations, and can suspend air conditioners and the like even in a location where other equipment such as piping is present.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, an embodiment of the present invention will be described in detail.

[0015] 1 to 10 are drawings such as a front view showing an example of a suspension rack according to an embodiment of the present invention. An air conditioner is suspended from this suspension rack. In the top view of Fig. 9, the extension frame part is hidden.

[0016] In the figure, reference numeral 1 denotes the suspension frame main body, which has a vertical column member 2 and a horizontal beam member 3. That is, four vertical column members 2, 2, 2, 2 are arranged in a quadrangle when viewed from above, and four horizontal beam members 3 are attached in multiple stages between them. They are fixed to each other using, for example, gussets G.

[0017] The vertical column members 2 and the horizontal beam members 3 are made of aluminum. A hanging member 5 made of stainless steel material is fixed to the upper end 2a of the vertical column members 2 and attached to the ceiling slab 4. The hanging member 5 is made of stainless steel material, which has the following advantages:

[0018] That is, the suspension frame body 1 is made of aluminum material, but aluminum material is weak against alkali and it is difficult to use because the ceiling slab 4 at the site is alkaline. Therefore, this problem is solved by using SS material for the suspension member 5 installed on the ceiling slab 4.

[0019] Furthermore, since aluminum is weaker than SS material, the hanging point of a frame with a long hanging length is affected by large forces due to large vibrations during an earthquake. However, by using SS material for hanging member 5, there are no problems with seismic performance and the structure is safe, even when subjected to forces due to large vibrations during an earthquake.

[0020] Furthermore, main body reinforcing members 9 made of SS material are diagonally connected to each planar space S formed by adjacent vertical column members 2 and horizontal beam members 3. This makes it possible to suppress displacement due to lateral shaking even with minimal suspension support when the equipment is shaken by large lateral shaking during an earthquake.

[0021] An extension frame section 6, which is larger than the suspension frame main body 1 when viewed from above, is fixed to the lower end 2b of the vertical column member 2. Reference numeral 2d in Fig. 10 denotes a bottom plate for fixing the lower end b of the suspension frame main body 1 to the extension frame section 6, which is abutted against the upper frame 6a from below and fixed with bolts.

[0022] The extension frame section 6 is made of aluminum material and has two upper frames 6a on the upper side and two lower frames 6b fixed to the lower side of the upper frames 6a so as to cross each other. The upper frames 6a are fixed to the lower ends 2b of the vertical column members 2, and the lower frames 6b are fitted with hanging fixtures 8 for suspending the air conditioner 7, which is the equipment to be suspended. Note that stainless steel material may be used as the material for the upper frames 6a, which will provide stronger earthquake resistance. 6a' in Figures 13, 14 and 15 shows this state.

[0023] Each of the two upper frames 6a is constructed by bolting two frame members with L-shaped cross-sections back-to-back, and is arranged in parallel with each other, with the distance between them being approximately as narrow as the width of the vertical column member 2.

[0024] The two lower frames 6b, which are fixed to the underside of the end portion 6a2 of the upper frame 6a so as to intersect at a right angle, are each composed of two frame members with an L-shaped cross section bolted back to back and arranged in parallel.

[0025] The distance between these two lower frames 6b is set to be considerably larger than the width of the vertical column member 2 and approximately the same as the width of the air conditioning equipment 7 that is to be suspended, since they are fixed to the end portion 6a2 of the upper frame 6a.

[0026] Furthermore, a suspender 8 is attached to each of the ends 6b1, 6b1, 6b1, 6b1 of the two lower frames 6b. Therefore, it is possible to suspend the air conditioner 7 according to the wide width. That is, since the two lower frames 6b are fixed to the end 6a2 of the upper frame 6a, the distance between the two lower frames 6b is wide, and furthermore, since the suspender 8 is attached to the end 6b1 of the lower frame 6b, as a result, the range of the four suspenders 8 in top view is considerably wider than the range of the suspension rack main body 1, and it is possible to accommodate even air conditioners having a wide range.

[0027] The suspender 8 can be hung down from the lower frame 6b, for example, by utilizing the gap at the joint between two L-shaped frame members of the lower frame 6b.

[0028] On the other hand, as shown in Figures 11 and 12, an expansion reinforcement member 10 is diagonally connected between the lower part 2c of the vertical column member 2 and the protruding portion 6a1 of the upper frame 6a that protrudes outward beyond the vertical column member 2.

[0029] 16 to 29 show specific usage states of the suspension rack according to the embodiment of the present invention. That is, there are many other pieces of equipment 11 such as pipes, ducts, and electric cable racks arranged near the ceiling, and an example is shown in which a wide item such as an air conditioner 7 is suspended without interfering with the other pieces of equipment 11.

[0030] Figure 30 is a front view of the hanging rack of the present invention excluding the hanging fixture 8, Figure 31 is a back view of the same hanging rack excluding the hanging fixture, Figure 32 is a right side view of the same hanging rack excluding the hanging fixture, Figure 33 is a left side view of the same hanging rack excluding the hanging fixture, Figure 34 is a top view of the same hanging rack excluding the hanging fixture, and Figure 35 is a bottom view of the same hanging rack excluding the hanging fixture.

[0031] 36 shows an invention related to the present invention, in which an electric rack 11a is suspended as the suspended equipment. That is, a suspender 8 is directly attached to an upper frame 6a, a lower frame 6b is connected to the suspender 8, and the electric rack 11a is suspended by the lower frame 6b.

[0032] Alternatively, Fig. 37 shows an invention related to the present invention, in which a pipe 11b is suspended as a suspending device. That is, a suspender 8 is directly attached to an upper frame 6a, a lower frame 6b is connected to the suspender 8, and the pipe 11b is suspended by the lower frame 6b.

[0033] The number of vertical column members 2 and horizontal beam members 3 is not limited to four, but may be three or five. [Industrial Applicability]

[0034] The suspension stand of the present invention is useful when suspending heavy objects such as air conditioners from the ceiling, since it can suspend wide target equipment without using heavy steel materials that require expertise such as welding, and without interfering with ducts installed in the ceiling.
