However, Patent Document 1 does not specifically disclose how to suspend and support building equipment such as range hoods.

The objective of this invention is to provide a suspension support plate and a support structure for equipment within a building that allows a high degree of freedom in adjusting the placement position of equipment within the building.

The suspension support plate of this invention has a plurality of first long hole portions formed on the periphery so that a plurality of first suspension members are inserted and secured thereto, and a second long hole portion located in the center within an area sandwiched or surrounded by the plurality of first long hole portions, through which a second suspension member is inserted and secured thereto, and is characterized in that the longitudinal direction of the first long hole portion intersects with the longitudinal direction of the second long hole portion.

With the above configuration, the building equipment can be suspended by the first suspension members inserted through the first long hole portions. The suspension plate in this suspended state is suspended by a member fixed to the building side by the second suspension member inserted through the second long hole portion. The position of the building equipment can be adjusted relative to the suspension plate within the longitudinal range of the first long hole portion. The position of the suspension plate itself can be adjusted within the longitudinal range of the second long hole portion. Since the longitudinal direction of the first long hole portion and the longitudinal direction of the second long hole portion intersect, the degree of freedom in adjusting the position of the building equipment is improved. In this way, the building equipment is suspended by the first suspension members via the suspension plate, so even heavy building equipment can be suspended and supported easily and stably.

The second long hole portion may be formed in the lower plate portion that is provided at a position lower than the upper surface of the center side, and an allowance hole portion may be formed in the upper surface located above the lower plate portion, through which the second hanging member is inserted and which allows the second long hole portion in the second hanging member to move in the longitudinal direction. In this way, a nut can be placed on the lower plate portion instead of on the upper surface of the center side of the hanging support plate, so that the hanging support plate can be abutted against the ceiling plate.

The first long hole may be formed in a lower portion on the peripheral side that is lower than the upper surface of the central side. This makes it possible to abut the hanging support plate against the ceiling plate without allowing the nut attached to the first hanging member that is inserted into the first long hole to protrude above the upper surface of the central side.

A rising portion may be formed on the edge of the lower portion, and the rising portion and the wall of the lower portion facing the rising portion may form a nut holding portion having a width that restricts the nut from spinning freely. This eliminates the need to prepare a separate member that restricts the nut from spinning freely, thereby reducing costs.

A through hole may be provided at a non-central position on the central side, penetrating the suspension support plate in the thickness direction. In this way, by inserting a sharpened member through the through hole into the ceiling surface material, the horizontal rotation of the suspension support plate can be restricted, facilitating the installation work of the building equipment.

The in-building equipment support structure of the present invention is characterized in that the second hanging member supported on the building side is inserted into the second long hole portion of the hanging support plate, and the in-building equipment is suspended by the first hanging member inserted into the multiple first long hole portions of the hanging support plate.

This invention has the effect of improving the freedom to adjust the placement of equipment within a building.

FIG. FIG. 2 is a perspective view showing a state in which a center hood is suspended by the suspension support plate of FIG. 1 . 1A is an explanatory diagram in plan view showing the relationship between the suspension support plate, the building side components, and the center hood in FIG. 1, and FIG. 1A, 1B and 1C are a plan view, a side view and a front view of a suspension support plate according to another embodiment.

An embodiment of the present invention will now be described with reference to the accompanying drawings. As shown in Figures 1(A), 1(B), 1(C) and 2(A) and 2(B), the suspension support plate 1 of the embodiment has a substantially rectangular outer shape and has a central side plate portion 1a located at the center, two peripheral side concave plate portions 1b located on the peripheral side and serving as reinforcing portions, and two peripheral side plate portions 1c similarly located on the peripheral side and serving as reinforcing portions. The two peripheral side concave plate portions 1b and the two peripheral side plate portions 1c are positioned opposite each other with the central side plate portion 1a in between.

The peripheral concave plate portion 1b has a lower stage portion (bottom portion) 1b-1 that is lower than the upper surface of the central side plate portion 1a. A rising portion 1b-2 is formed on the edge of this lower stage portion 1b-1, and a concave shape is formed by the rising portion 1b-2 and a wall portion 1b-3 of the lower stage portion 1b-1 that faces the rising portion 1b-2.

Two first long hole portions 11 are formed in each of the lower step portions (bottom portions) 1b-1 of each peripheral concave plate portion 1b, and a total of four first long hole portions 11 are located near the four corners of the approximately rectangular suspension support plate 1.

As shown in FIG. 3, a first hanging member 3 is attached to each of the first long holes 11. Each of the first hanging members 3 includes a double-ended bolt 31 and a number of nuts 32 that are screwed onto the double-ended bolt 31.

As shown in FIG. 1(A), the first long hole portion 11 has a wide hole portion 11a and a narrow hole portion 11b. The wide hole portion 11a is large enough to insert the nut 32 of the first hanging member 3. The narrow hole portion 11b is narrower than the width of the nut 32 and wider than the diameter of the double-cut bolt 31. The wide hole portion 11a is located toward the center of each peripheral concave plate portion 1b. The first hanging member 3 is engaged with the first long hole portion 11 within the range of the narrow hole portion 11b.

In addition, the distance between the rising portion 1b-2 and the wall portion 1b-3 facing the rising portion 1b-2 of each peripheral concave plate portion 1b is slightly wider than the distance between the opposing parallel sides of the polygonal side of the nut 32, and the concave plate portion 1b functions as a nut holding portion having a width that restricts the nut 32 from spinning freely.

A lower plate 2 is provided on the central underside of the central side plate 1a. The lower plate 2 has an inverted hat-shaped cross section, and the rising pieces 2a, 2a located on both sides are fixed to the underside of the central side plate 1a by welding or the like. The lower plate 2 also has a lower plate 2b located between the rising pieces 2a, 2a and spaced apart from the central side plate 1a.

A second long hole 22 is formed in the lower plate 2b. The second long hole 22 is located within the area surrounded by the four first long holes 11 and near the center of gravity of the suspension support plate 1.

The longitudinal direction of the first long hole portion 11 and the longitudinal direction of the second long hole portion 22 intersect with each other.

As shown in FIG. 3, the second hanging member 4 is inserted into the second long hole portion 22. The second hanging member 4 includes, for example, a double-ended bolt 41 and a number of nuts 42 that are screwed onto the double-ended bolt 41.

The second long hole portion 22 has a generally circular wide hole portion 221 through which the nut 42 of the second hanging member 4 can be inserted, and a narrow long hole portion 222 that is narrower than the width of the nut 42 and wider than the double-cut bolt 41. The second hanging member 4 is engaged with the second long hole portion 22 within the range of the narrow long hole portion 222. The central side plate long hole portion (allowable hole portion) 12 formed in the central side plate portion 1a consists only of a long hole portion having a width that allows the nut 42 to be inserted.

The distance between the central side plate portion 1a and the lower plate portion 2b is higher than the height of the nut 42. In this embodiment, as shown in FIG. 3, one nut 42 is screwed onto the portion of the double-cut bolt 41 located on the upper side of the lower plate portion 2b, and two nuts 42 are screwed onto the portion of the double-cut bolt 41 protruding from the lower side of the lower plate portion 2b, and the double-cut bolt 41 is fixed to the lower plate portion 2b by tightening these nuts 42. Not limited to screwing two nuts 42 together (double nut), single nut tightening may be performed using a washer.

In addition, four through holes 14 are formed in non-central positions on the central side plate portion 1a, penetrating the suspension support plate 1 in the thickness direction.

Figure 4 shows an example of a building equipment support structure using the suspension support plate 1. In this example structure, a center hood (mantle hood) 5 is suspended and supported by the suspension support plate 1 as the building equipment. A roughly U-shaped locking fitting 52 consisting of a lower piece and an upper piece and a standing piece connecting them is welded to the upper end of the square tube portion 51 of the center hood 5. The double-ended bolt 31 of the first suspension member 3 is inserted into the bolt insertion portion formed in the upper piece, and multiple nuts 32 screwed onto the double-ended bolt 31 clamp the upper piece from above and below and tighten it.

As shown in Fig. 5(A) and Fig. 5(B), the second hanging member 4 is inserted into the second long hole portion 22 of the hanging support plate 1. The second hanging member 4 is supported through a long hole portion 61a formed in a portion of the support 61 fixed to the cross member 6 on the building side that protrudes from the cross member 6. The longitudinal direction of this long hole portion 61a is parallel to the longitudinal direction of the first long hole portion 11. In this embodiment, the second hanging member 4 can be passed from the central side plate long hole portion 12 formed in the central side plate portion 1a to the wide hole portion 221 of the second long hole portion 22 formed in the lower plate portion 2b. The double-cut bolt 41 of the second hanging member 4 is passed through the narrow long hole portion 222 of the second long hole portion 22 and engaged in the narrow long hole portion 222. For the multiple nuts 42 screwed onto the second hanging member 4, for example, one nut 42 is positioned above the lower plate portion 2b, and two nuts are positioned below the lower plate portion 2b, and the height is adjusted before the nuts 42 are tightened. During this height adjustment, the hanging support plate 1 is abutted against the ceiling plate 7.

A duct 51b is connected to the exhaust pipe 51a protruding from the upper part of the square tube portion 51 of the center hood 5. This duct 51b is passed between the two first hanging members 3. In this embodiment, the duct 51b is surrounded by the descending ceiling portion 71.

The above-mentioned suspension support plate 1 can support the center hood 5, which is an in-building equipment, by the multiple first suspension members 3 inserted into the multiple first long holes 11. The suspension support plate 1 in this suspension support state is supported by the cross member 6 fixed to the building side by the second suspension member 4 inserted into the second long hole 22. The position of the center hood 5, etc. relative to the suspension support plate 1 can be adjusted within the longitudinal range of the first long hole 11. Furthermore, the position of the suspension support plate 1 itself can be adjusted within the longitudinal range of the second long hole 22. Since the longitudinal direction of the first long hole 11 and the longitudinal direction of the second long hole 22 intersect, the degree of freedom in adjusting the position of the center hood 5, etc. is improved. Furthermore, since the in-building equipment is supported by the multiple first suspension members 3 via the suspension support plate 1 in this way, even heavy in-building equipment can be supported by hanging easily and stably.

When the second long hole portion 22 is formed in the lower plate portion 2b, which is located at a position lower than the upper surface of the central side plate portion 1a, the nut 42 can be placed on the lower plate portion 2b instead of on the upper surface of the central side plate portion 1a of the hanging support plate 1, so that the hanging support plate 1 can be abutted against the ceiling plate 7.

When the first long hole portion 11 is formed in the lower portion (bottom portion) 1b-1 of each peripheral concave plate portion 1b, the nut 32 screwed into the first hanging member 3 inserted into the first long hole portion 11 does not extend above the upper surface of the central side plate portion 1a, making it possible to abut the hanging support plate 1 against the ceiling plate 7.

When each peripheral concave plate portion 1b functions as a nut holding portion having a width that restricts the nut from spinning freely, there is no need to prepare a separate member to restrict the nut 32 from spinning freely, which reduces costs.

By providing a through hole 14 that penetrates the suspension support plate 1 in the thickness direction at a non-center position of the central side panel portion 1a, the horizontal rotation of the suspension support plate 1 can be restricted by inserting a sharpened member into the ceiling plate 7 through the through hole 14, facilitating the installation work of the center hood 5, etc.

In the above embodiment, the peripheral side concave plate portion 1b functions as a nut holding portion having a width that restricts the nut from spinning freely, but this is not limited to the above. As shown in Figures 6(A), 6(B), and 6(C), the width of the concave shape of the peripheral side concave plate portion 1b may be a width that causes the nut 32 to spin freely. In this case, the nut 32 can be prevented from spinning freely by using an accessory that has a width that does not allow spinning within the peripheral side concave plate portion 1b and has a receiving portion into which the nut 32 fits.

The suspension support plate 1 is configured to suspend a center hood 5, which is a heavy piece of building equipment, but it can also be configured to suspend lighting fixtures and other heavy pieces of building equipment, not limited to a center hood 5. Although four first suspension members 3 are arranged, three or two may be arranged. When two first suspension members 3 are arranged, the second suspension member 4 is positioned in the area sandwiched between the two first suspension members 3.

Although an embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.
