Description

  The present invention relates to a vibration suppression body for a suspension bolt, and more particularly to a vibration suppression body that suppresses vibration of a suspension bolt that suspends a suspension structure such as an air conditioner or piping from a ceiling casing.

  Various equipment such as an indoor unit and piping of an air conditioner are arranged on a ceiling portion such as a ceiling slab or deck plate of a building such as a building. These equipments are generally supported on a ceiling by being fixed to a suspension bolt that is suspended and secured to a ceiling housing such as a ceiling slab or deck plate. For example, FIG. 7 shows an indoor unit of an air conditioner that is suspended from four suspension bolts, and the upper ends of the four suspension bolts are embedded and fixed to the ceiling frame using anchors or the like.

  These ceiling-supported structures (referred to as suspended structures in this specification) are configured so that damage to the building itself is avoided by the earthquake-resistant structure and vibration isolation mechanism of the building during an earthquake. However, it has not yet been possible to prevent the suspension structure suspended from the ceiling from shaking and vibrating.

  Therefore, a vibration load acts on the suspension bolt that suspends the suspension structure from the ceiling, and there is a problem that deformation or breakage may occur.

  According to the inventor's research, it has been found that deformation and breakage of the suspension bolt are often caused by stress concentration particularly at the root portion fixed to the ceiling frame.

  Therefore, instead of having a single suspension bolt, it is divided at the base portion, and a connecting member that allows vibration in the front and rear, left and right directions, etc. is interposed in this divided portion to avoid deformation and breakage of the suspension bolt at the root portion. The structure which performs is proposed (for example, refer patent document 1).

  Next, the present invention will be described with reference to the accompanying drawings.

The vibration suppression body (hereinafter also referred to as a vibration suppression body) of the suspension bolt according to the present invention suspends a suspension structure 4 such as an air conditioner or piping as shown in FIG. It is a technology that suppresses vibration of the hanging bolts 3, 3, 3, 3 to be lowered, and as a specific configuration example, as shown in FIGS. 1 to 3,
A structure in which a suspension structure 4 is attached to a suspension bolt 3 suspended from a ceiling housing 2 such as a ceiling slab or a deck plate to suspend the suspension structure 4, and a vibration load acting on the suspension bolt 3 is reduced to suppress vibration. In the vibration suppression body 1 of the suspension bolt of
The vibration suppressing body 1 is attached to and fixed to the lower surface 21 of the ceiling casing 2, an abutment section 12 that is in contact with the outer periphery of the suspension bolt 3, and the mounting and fixing section 11. A connecting portion 13 that connects the contact portion 12 and
The connecting portion 13 has at least elasticity, and when vibration energy is input to the suspension bolt 3, the elasticity of the connecting portion 13 is applied in a direction opposite to the vibration direction of the input vibration energy. The vibration energy is suppressed or eliminated by exerting a force.

  Hereinafter, the vibration suppressing body 1 of the present invention will be described in more detail.

  As shown in FIG. 1, the attachment fixing part 11 is attached and fixed to the lower surface 21 of the ceiling casing 2 by fixing means 5 such as bolts. As shown in FIG. 3, through holes 11 </ b> A and 11 </ b> A for inserting fixing means are formed in the attachment fixing portion 11.

  As shown in FIGS. 1 to 3, the contact portion 12 preferably has a configuration in which a protrusion 12 </ b> A that contacts the outer periphery of the suspension bolt 3 is provided on the inner surface, and more preferably, the contact portion 12 is configured to the outer periphery of the suspension bolt 3. The upper end and / or the lower end (both the upper end and the lower end in this embodiment) of the contact surface of the contact portion 12 are in contact with each other with a curved surface.

  By providing the ridge 12A on the inner surface of the contact portion 12, the contact portion 12 contacts the outer periphery of the suspension bolt 3 so that the upper end and the lower end of the contact portion 13 are in contact with each other on a curved surface. According to this configuration, since the contact end of the suspension bolt 3 and the contact portion 13 are in surface contact, stress concentration of vibration energy on the contact end can be avoided, and the root portion of the suspension bolt 3 can be avoided. In addition, deformation and breakage of the suspension bolt 3 at the contact end can be prevented.

  For example, in the present embodiment shown in FIGS. 1 to 3, the protrusion 12 </ b> A provided on the inner surface of the contact portion 12 is provided by pressing a part of the contact portion 12 in the inner surface direction.

  The vibration suppressing body 1 having the above configuration can use a metal plate-like material or a synthetic resin plate-like material which is a publicly known material used for a pipe support, and the plate-like material itself has elasticity. It is possible to adopt a configuration in which other members having elasticity are added to the plate-like material, but the most preferable is elasticity as used for a pipe support band which is a typical pipe support tool. It is a metal plate-shaped material.

  The vibration suppressing body 1 having the mounting and fixing portion 11, the contact portion 12 and the connecting portion 13 is preferably formed from a single elastic plate-like material. In this case, for example, FIG. Alternatively, as shown in FIG. 5, one elastic plate-like material 10 having an E-shape (see FIG. 4) or a U-shape (see FIG. 5) can be used.

  As an example of the molding process of the vibration suppressing body 1 in the case of using a single elastic plate-like material 10 having an E-shape or a U-shape, the upper horizontal line portion is set rearward with respect to the vertical line portion. A mounting fixing portion 11 is formed that is bent and fixed to the lower surface 21 of the ceiling casing 2, and the lower horizontal line portion is in front of the vertical line portion and the outer periphery of the suspension bolt 3 is in contact with the surrounding area Thus, a configuration in which the contact portion 12 is formed by bending may be mentioned. The E-shaped vertical line portion and the U-shaped vertical line portion together form the connecting portion 13.

  According to the vibration suppression body 1 of the present invention having the above-described configuration, the suspension bolt 3 has its outer periphery supported by the contact portion 12 regardless of the vibration direction of vibration energy input to the suspension bolt 3. Since the connection portion 13 of the vibration suppressing body 1 is in contact with the surrounding state and has elasticity against the input vibration energy, the biasing force due to the elasticity acts in a direction opposite to the vibration direction. As a result, the vibration energy can be suppressed or eliminated.

  The vibration suppression body of the present invention having the above configuration is configured to be inserted and attached from the end (lower end) of the suspension bolt 3, for example.

  As mentioned above, although the vibration suppression body of the suspension bolt based on this invention was demonstrated based on the Example, this invention is not limited to the said Example, Other aspects can be taken within the scope of the present invention.

  For example, the protrusion 12A provided on the inner surface of the contact portion 12 is not limited to the press molding of the above embodiment, and may be configured by cutting and forming a part of the contact portion 12, or The structure which arrange | positioned the elastic material which contact | abuts the outer periphery of the suspension bolt 3 to the inner surface of the contact part 12 by fixation etc. may be sufficient. Examples of the material of the elastic material include material configurations such as synthetic rubber, natural rubber, soft synthetic resin, and mixtures thereof.

  Further, as shown in FIG. 6, by adding a reinforcing rib to the connecting portion 13, the strength of the connecting portion 13 can be improved to the extent that elasticity is not lost. According to such a configuration, the vibration energy can be suppressed or eliminated by improving the strength of the connecting portion 13.

  The reinforcing rib that improves the strength of the connecting portion 13 is provided in the longitudinal direction that is the same as the axial direction of the suspension bolt 3. For example, in the configuration example shown in FIGS. 6 (A) and 6 (B), the reinforcing rib 13A is provided by press-molding at least a part of the connecting portion 13. 6A shows a configuration in which the connecting portion 13 is press-molded into a tunnel-like bent state, and FIG. 6B shows a configuration in which the connecting portion 13 is press-molded into an Ω-shaped bent state.

  In the configuration example shown in FIG. 6C, the reinforcing rib 13A is provided by bending a part of the connecting portion 13. In other words, a mountain-shaped reinforcing rib 13A is formed by bending a part of the connecting portion 13 into a V-shaped acute angle state.

  Further, the reinforcing rib 13A of the connecting portion 13 is not limited to press molding or bending formation, and is provided by adding a reinforcing rib 13A which is a member different from the connecting member 13 as shown in FIG. You can also.

Furthermore, in the said Example, although the contact surface to the suspension bolt 3 outer periphery of the contact part 12 was made into the smooth surface, it meshes | engages with the thread groove which consists of the protrusion and recess of the suspension bolt 3 on the surface of the said contact surface. It is good also as a structure which provided the recessed part and / or the convex part. According to this configuration, the contact area of the contact portion 13 of the vibration suppressing body 1 with respect to the suspension bolt 3 is increased, and displacement of the contact portion 12 in the axial direction of the suspension bolt 3 is suppressed. Therefore, the suppression or disappearance effect of vibration energy is significantly improved.
Further, due to the engagement of the suspension bolt 3 and the contact portion 12, the biasing force of the vibration suppressing body 1 facing the vibration energy is not only in the reverse direction of the vibration energy but also in the spiral direction of the thread groove of the suspension bolt 3. As a result, the vibration energy suppression or extinction effect is further improved.
Note that, in the case of the configuration in which the ridge 12A is provided on the inner surface of the contact portion 12 as in the present embodiment, the above-described recess and / or projection is provided on the contact surface of the ridge 12A. It is preferable.

  Further, the position of the contact portion 12 of the vibration suppressing body 1 that contacts the suspension bolt 3 is a position near the upper portion of the portion where the suspension structure 4 is attached to the suspension bolt 3 (the position indicated by reference numeral 3A in FIG. 7). In this case, vibration energy at a position close to the attachment position of the suspension structure 4 can be reduced, so that deformation and breakage of the suspension bolt 3 can be further prevented.

  Furthermore, in the above embodiment, the vibration suppression body 1 is inserted from below the suspension bolt 3, but the vibration suppression body 1 may be attached from the side instead of from below the suspension bolt 3. According to such a configuration, the vibration suppressing body 1 can be attached to the existing suspension bolt 3 to which the suspension structure 4 has already been suspended and fixed without removing the suspension structure 4. The construction period can be shortened and the construction cost can be reduced.

  As a structure which can attach the vibration suppression body 1 from the side of the suspension bolt 3, for example, a structure as shown in FIGS. This is a two-member configuration of a contact base 12B having a shape and a contact tip 12C having a circular arc shape that can surround the outer periphery of the suspension bolt 3 by being coupled to the corresponding contact base 12B.
