Description

  The present invention relates to a vibration isolator for installing equipment with large vibrations such as an air conditioner, and more particularly to a structure in which two long base units are connected side by side.

  Conventionally, in this type of anti-vibration stand, the members constituting the anti-vibration stand are connected not by welding but by fastening means such as screws so that they can be disassembled in consideration of convenience during transportation and inventory. Many are structured and assembled at the installation site.

  In this way, in the anti-vibration gantry that is assembled at the installation location, in order to avoid the complexity of the connection structure of the vertical and horizontal members constituting the gantry, the corner member is used to connect the vertical member and the horizontal member. There are some that connect the members.

  For example, Patent Document 1 discloses a vibration isolation table in which frame members constituting a mounting frame and a base frame are brought into contact with each other at a corner portion and fastened with a screw via a connecting metal fitting.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 shows an embodiment in which the vibration isolator according to the present invention is applied to a so-called air conditioner anti-vibration table, in which FIG. 1 (a) is a plan view, FIG. 1 (b) is a front view, c) is a side view. As shown in the figure, the vibration isolator 1 is for installing an air conditioner outdoor unit (not shown), and is a long frame unit 3 (a so-called rail type vibration isolator) having an upper frame 5 and a lower frame 7. ) Are arranged side by side and arranged side by side, and beam members 9 and 9 described later are bridged and connected to both ends thereof.

  In the following description, the direction in which the upper base 5 extends is the vertical direction, and the arrangement direction of the upper base 5 is the horizontal direction. In the following description, the corner portion positioned at the lower right in FIG. 1A will be described, but the other corner portions have substantially the same configuration as the corner portion positioned at the lower right.

  In this anti-vibration gantry 1, the gantry units 3 and 3 that make a pair are the same, and a long upper gantry 5 and a lower gantry 7 each made of a square pipe material (for example, a square steel pipe for structure) having a rectangular cross section are provided. The two isolators (anti-vibration bodies) 11 and 11 are interposed in the vertical direction and spaced apart in the vertical direction. The isolator 11 reduces vibration transmission between the upper pedestal 5 and the lower pedestal 7, and for example, a coil spring and a rubber that are integrally formed, or a resin case that incorporates a coil spring is used.

  In the gantry unit 3 of the present embodiment, the lower gantry 7 is longer than the upper gantry 5, and both end portions thereof protrude outward in the vertical direction from the ends of the upper gantry 5.

On the side edge on the inner side in the longitudinal direction of the extending portion 19e, a wife wall portion 19g that is bent upward is formed, and the side wall edge 19g and the inner extending portion 19f are substantially parallel to each other in plan view. It is connected in an L shape.

  Further, an outer extending portion 19d that is bent inward in the vertical direction and extends along the outer surface of the laterally outer side wall 5c of the upper base 5 is formed on the side edge of the lateral wall portion 19b in the lateral direction. The outer extending portion 19d is formed with a screw hole 19h having a rectangular cross section extending in the lateral direction, and the outer extending portion 19d is laterally outward of the upper base 5 by a screw 25 inserted into the screw hole 19h. It is fastened to the side wall 5c.

  As shown in FIG. 3B, the side wall portion 19c of the upper seismic bracket 19 has a convex side 19j formed on the side edge on the outer side in the vertical direction, and is used for coupling with the beam member 9 as will be described later. Further, a bolt through hole 19i extending in the vertical direction is formed through the floor wall portion 19a of the upper seismic bracket 19, and the shaft portion of the seismic bolt 23 is inserted into the bolt through hole 19i in a loosely fitted state. . The seismic bolt 23 is arranged so that its shaft portion extends upward through the lower seismic bracket 21 (round hole 21e) and the upper wall 7a of the lower platform 7 that overlaps the lower seismic bracket 21 (round hole 21e). It is fastened to the upper wall 7a of the lower pedestal 7 by nuts 27 and 29 that are screwed into the base.

  Further, as shown in FIG. 5, a rubber bush 31 is externally inserted into a portion of the shaft portion of the seismic bolt 23 inserted into the bolt through hole 19 i of the floor wall portion 19 a of the upper seismic bracket 19. The rubber bush 31 includes a cylindrical portion having a diameter slightly smaller than that of the bolt through hole 19i and a flange portion connected to the cylindrical portion, and the flange portion is in contact with the peripheral portion of the bolt through hole 19i from above. A nut 35 is screwed onto the shaft portion of the seismic bolt 23 with a plain washer 33 interposed therebetween.

Furthermore, since the guide top wall portion 15b extends further outward in the vertical direction than the side edges on the outer side in the vertical direction of the guide side wall portions 15a and 15a, the lower surface of the guide top wall portion 15b and the vertical direction of the guide side wall portion 15a. As shown in FIG. 5, the outer side edge and the upper edge of the guide extension 15 c are substantially U-shaped when viewed from the lateral direction. By forming the guide member 15 in this way, the guide top wall portion 15b, the guide side wall portion 15a, and the guide extension portion 15c open to the outside in the vertical direction in which a mounting portion 17 of a beam member 9 described later is fitted. The fitting part 37 is comprised.

  On the other hand, the beam member 9 that connects the pair of upper supports 5 and 5 that are paired with each other is formed by bending a ZAM steel plate (registered trademark), and as shown in FIG. A beam member main body (fourth plate portion) 9a that is disposed and extends in the lateral direction; and a mounting portion 17 that protrudes inward in the vertical direction from the upper edge of the beam member main body 9a and is fitted into the fitting portion 37. doing.

  As shown in FIG. 9B, the beam member main body 9a is formed in an inverted T shape, and a folded portion 9b that is bent obliquely upward to increase rigidity is formed on the lower edge thereof. ing. Further, projecting pieces 9c and 9c projecting outward in the lateral direction are respectively formed on the lateral edges on the laterally outer side in the lower end portion of the beam member main body 9a. These projecting pieces 9 c and 9 c are configured to come into contact with the laterally outer edge of the side wall portion 19 c of the upper seismic bracket 19 in a state where the beam member 9 is attached to the upper base 5. When the beam member 9 is fitted into the guide member 15 by applying the upper end of the protruding piece 9c to the lower end of the convex side 19j formed on the side edge 19c of the side wall portion 19c of the upper seismic bracket 19 in the vertical direction. This facilitates positioning in the vertical direction.

  The mounting portion 17 is a top plate portion (first plate portion) 17a that is bent at the upper edge of the beam member main body 9a and extends inward in the vertical direction, and a saddle plate portion that extends downward from a side edge on the inner side in the vertical direction of the top plate portion 17a. (Second plate portion) 17b and an inclined plate portion (third plate portion) 17c extending downwardly inclined toward the outside in the longitudinal direction from the lower edge of the flange plate portion 17b. The angle formed between the top plate portion 17a and the beam member main body 9a is the side edge of the guide top wall portion 15b and the side wall portion 19c of the upper seismic bracket 19 on the outer side in the vertical direction when viewed from the lateral direction (the vertical outer side of the upper platform 5). It is set to be smaller than the angle formed with the edge. The angle formed between the top plate portion 17a and the inclined plate portion 17c is set larger than the angle formed between the lower surface of the guide top wall portion 15b and the upper edge of the guide extension portion 15c.

  Thus, the top plate portion 17a, the flange plate portion 17b, and the inclined plate portion 17c are substantially U-shaped when viewed from the lateral direction, and are inclined downward as the inclined plate portion 17c goes outward in the vertical direction. Therefore, it is easily elastically deformed mainly in the vertical direction.

  As shown in FIG. 9A, the top plate portion 17a has notched groove portions (groove portions) 17d and 17d extending in the vertical direction and opening inward in the vertical direction at positions corresponding to the guide protruding wall portions 15d and 15d. Two are formed. The tongue-like portion 17e sandwiched between the notched groove portions 17d and 17d is formed in a semicircular shape in plan view so that the guide protruding wall portions 15d and 15d are not caught when the attachment portion 17 is fitted into the fitting portion 37. A through hole 17f is formed in the tongue portion 17e (a portion overlapping the guide top wall portion 15b).

  As shown in FIG. 10, the mounting portion 17 formed in this way has a laterally inner side edge of the laterally inner notch groove portion 17 d as a laterally inner guide protruding wall portion 15 d and a laterally outer side. When the laterally outer side edge of the notch groove portion 17d is applied to each fitting portion 37 from the outer side in the longitudinal direction while the laterally outer side guide protrusion wall portion 15d is applied, the inclined plate portion 17c contacts the stopper portion 15g. By contacting, the attachment portion 17 enters the fitting portion 37 while being elastically deformed mainly in the vertical direction.

  Then, when the inclined plate portion 17c gets over the stopper portion 15g by hitting the beam member 9 from the outside in the vertical direction using a small hammer or the like, the upper surface of the top plate portion 17a, the lower surface of the guide top wall portion 15b, and the vertical plate The mounting portion 17 is fitted in a state in which the longitudinal inner side surface of the portion 17b, the side edge of the guide side wall portion 15a on the outer side in the longitudinal direction, the lower surface of the inclined plate portion 17c, and the upper edge of the guide extension portion 15c are in contact with each other. It is inserted into the part 37. At this time, the inclined plate portion 17c is sandwiched between the stopper portion 15g and the guide side wall portion 15a so that the longitudinal outer end thereof is caught by the stopper portion 15g, and the protruding pieces 9c and 9c of the beam member main body 9a. Is the side edge of the side wall portion 19c of the upper seismic bracket 19 on the outer side in the vertical direction.

Further, protruding guide wall portions 15d, 15d has two notches grooves 17d, enters respectively 17d, laterally inward of the side edges of laterally inboard of the cutout groove 17d is the inner lateral guide projecting wall portion 15 d while riding over the lateral outer side edges of laterally outward of the cutout groove 17d is ride laterally outwardly protruding guide wall portion 15 d. Furthermore, the launch portion 15j formed on the guide top wall portion 15b is fitted into the through hole 17f of the top plate portion 17a.

  As described above, when the mounting portion 17 is fitted into the fitting portion 37, the angle formed between the top plate portion 17 a and the inclined plate portion 17 c is above the lower surface of the guide top wall portion 15 b and the guide extension portion 15 c. Since the angle is set larger than the angle formed with the edge, the top plate portion 17a presses the lower surface of the guide top wall portion 15b upward, and the inclined plate portion 17c presses the upper end edge of the guide extension portion 15c downward. Therefore, loosening of the beam member 9 and the guide member 15 due to the moment acting in the direction of the white arrow in FIG. 5 is restricted.

Further, laterally inboard of the side edges of laterally inboard of the cutout groove 17d is run on the laterally inward protruding guide wall portions 15 d, and, are laterally outboard of the side edges of laterally outward of the cutout groove 17d Since the top plate portion 17a is strongly pressed against the lower surface of the guide top wall portion 15b because it rides on the laterally outer guide protruding wall portion 15d, the relative movement between the beam member 9 and the guide member 15 in the vertical direction Is regulated.

  Furthermore, the top plate portion 17a and the guide top wall portion 15b are in close contact with each other, and the angle formed between the top plate portion 17a and the beam member main body 9a is such that the guide top wall portion 15b Since it is set to be smaller than the angle formed with the side edge of the side wall portion 19c of the seismic bracket 19 in the longitudinal direction, the protruding pieces 9c, 9c of the beam member main body 9a press the side wall portion 19c so as to tighten it. In other words, the beam member 9 is attached to the upper frame 5 so that the top plate portion 17a and the beam member main body 9a sandwich the end of the upper frame 5 from above and from the outside in the vertical direction. The looseness between the beam member 9 and the guide member 15 due to the moment acting in the direction of the pull arrow is further restricted.

It constitutes a regulation means.

  On the other hand, when the attachment portion 17 is fitted into the fitting portion 37, the longitudinal outer end of the inclined plate portion 17c is hooked (engaged) with the stopper portions 15g and 15g, and the guide sidewall portions 15a and 15a are laterally outer. Since the convex sides 15h and 15h formed on the side edges of the plate press the flange plate portion 17b, the relative movement between the beam member 9 and the gantry 5 in the vertical direction is restricted.

  In addition, the projecting portion 15j formed in the guide top wall portion 15b is fitted into the through hole 17f of the top plate portion 17a, thereby further restricting the relative movement between the beam member 9 and the upper base 5 in the vertical direction. Is done.

  Thus, the stopper portions 15g, 15g, the inclined plate portion 17c that presses the stopper portion 15g, the guide side wall portions 15a, 15a (convex sides 15h, 15h), and the gutter plate portion 17b that presses the guide side wall portion 15a. And the through hole 17f and the projecting portion 15j fitted into the through hole 17f, the second restricting means for restricting the backlash in the vertical direction between the beam member 9 and the upper base 5 according to the present invention. Is configured.

Further, the lateral inner side edges of laterally inboard of the cutout groove 17d is run on the laterally inward protruding guide wall portions 15 d, and, are laterally outboard of the side edges of laterally outward of the cutout groove 17d by ride laterally outward protruding guide wall portions 15 d, in the transverse direction since the top plate portion 17a is pressed laterally inward and outward by the guide projection wall portion 15d, the beam member 9 and the guide member 15 Relative movement is restricted.

  As a result, the guide projecting wall portion 15d and the notched groove portions 17d and 17d constitute third regulating means for regulating rattling in the lateral direction between the beam member 9 and the gantry 5 in the present invention. doing.

  In addition, by adopting a structure in which the guide projecting wall portion 15d extending in the vertical direction is fitted into the notched groove portions 17d and 17d extending in the vertical direction, for example, unlike the case where the convex portion is fitted in the concave portion. Since the angle formed between the gantry unit 3 and the beam member 9 is difficult to change in a plan view, it is possible to suppress the vibration isolating gantry 1 assembled in a rectangular shape from being deformed into a parallelogram shape.

  When disassembling the assembled anti-vibration mount 1, an elongated tool such as a screwdriver is inserted into the recess 15l formed on the upper edge of the guide extension 15c, 15c in the longitudinal direction of the stopper 15g. To do. Then, when the handle portion of the tool is pushed down with the lower edge of the recess 15l as a fulcrum, the inclined plate portion 17c is pushed upward by the tip portion of the tool, and the longitudinal outer end of the inclined plate portion 17c and the stopper portion The engagement with 15g is released.

  Then, when the beam member 9 is pulled outward in the longitudinal direction in a state where the inclined plate portion 17c and the stopper portion 15g are disengaged, the attachment portion 17 is easily detached from each fitting portion 37. As described above, the vibration isolator 1 according to the present embodiment is easy to disassemble as well as to assemble, but conversely, the inclined plate portion 17c is intentionally inserted by inserting a tool into the recess 15l. As long as the engagement between the stopper portion 15g and the stopper portion 15g is not released, the structure is difficult to disassemble.
