Description

  The present invention relates to a fixing jig capable of allowing a displaceable object to be displaced by a certain amount with respect to the object to be fixed and suppressing displacement of the object to be fixed by a certain amount or more. More specifically, the present invention includes a fixing member, a clamping member, and a connecting member. The fixing member has means for fixing to a fixed object and means for holding the connecting member, and the clamping member is attached to an object to be fixed. A means for contacting and means for holding the connecting member, and an object to be fixed can be inserted between the holding member and the fixed object. For example, the present invention relates to a fixing jig in which a penetrating part capable of moving a connecting member is formed.

In construction, traditionally, a wooden floor is fixed to a floor slab or wall on the floor periphery of a double floor, and the floor periphery is fixed to the wooden floor. Was preventing. However, this method has a drawback in that, when subjected to a heavy floor impact, the floor slab or wall is shaken to deteriorate the heavy floor impact sound. Therefore, as a method of not deteriorating the heavy floor impact sound, a method of using a joist with an impact absorbing material or a wood piece or a rubber piece as a sinking preventing material for preventing sinking of a certain amount or more has been proposed (for example, Patent Document 1). reference).
JP 2003-160992 A

  However, this method cannot sufficiently prevent the floor from floating or bottoming, and if the moisture content of the floor frame increases due to rainfall or snowfall before the roof in the middle of the construction is completed, it is necessary to sledge the base plate. The floor floating state fluctuated, and there was a drawback that performance such as sufficient suppression of floor impact sound was not achieved.

  An object of the present invention is to develop a novel fixing jig that can set reliable displacement performance and can sufficiently exhibit vibration and shock absorption performance by a displaceable object to be fixed.

  The present invention is a fixing jig for fixing a displaceable object to be fixed, and includes a fixing member, a holding member, the fixing member, and a connecting member that connects the holding member, and the fixing member Has a holding part that holds the connecting member, and a holding part that holds the connecting member, and the holding member holds the connecting member and the contact part that contacts the fixed object. The fixed object can be inserted between the holding member and the fixed object, and a predetermined amount of the fixed member and the holding member is connected between the fixing member and the holding member at a connecting portion of the fixing member and the holding member. The present invention relates to a fixing jig characterized in that a movable range is set.

  The present inventor has made various types of fixing jigs and examined them in order to develop new fixing jigs that can be used for joists with shock absorbers. At that time, the inventor mainly selects a thing having a vibration or shock absorption capability as a fixed object, and when fixing the fixed object to the fixed object, the inventor absorbs vibration or shock on the fixed object. A search was made for a fixing jig that can be fixed while allowing the required constant displacement.

  In particular, such a fixing jig has the function of a joist without deteriorating the heavy floor impact sound, and does not deteriorate the performance of the conventional joist without deteriorating the heavy floor impact sound. It also has a function to prevent the floor from rising and bottoming out. In other words, in the past, the joist on the double floor was to fix the wooden joist to the floor frame or wall, and to fix the outer circumference of the floor to the joist, so the heavy floor impact sound was getting worse. . In addition, as a method of not deteriorating the heavy floor impact sound, there has been proposed a method using a joist with a shock absorbing material or a material provided with a sink preventive material so as not to sink more than a certain amount. If there is rainfall or snowfall before the roof is completed, the moisture content of the floor frame will increase, the floor will float due to warpage of the base plate, and the soundproofing performance will decrease, and the shock absorber will be damaged and function. The failure could not be suppressed sufficiently.

  Therefore, the present inventor fixes the fixed object to the fixed object so as to have an upper limit and a lower limit of the displacement while securing a certain amount of displacement allowance for exhibiting the shock absorbing ability to the fixed object. The fixing jig was examined in detail, and the present invention was achieved.

  The fixing jig of the present invention can be used for shock absorbers such as floor joists, etc., so that functions such as conventional joists can be stably exhibited, and floor floating and bottoming can be suppressed, The heavy floor impact sound is not deteriorated. Moreover, it is possible to prevent more than a certain amount of sinking due to heavy furniture.

  Further, the fixing jig of the present invention is not limited to a horizontal installation such as a joist at the floor. For example, by using the fixing jig in the vertical direction at the lower part of the wall of a parking lot, the vehicle can be prevented from being damaged. It can also be used for etc. Thus, many uses can be considered by giving a fixed object a function of absorbing vibration and shock.

  The purpose of the present invention is to provide a reliable displacement performance in a fixing jig and to stably exhibit sufficient absorption performance of vibration and impact by the object to be fixed, with the minimum number of parts and without impairing workability. Realized. The fixing jig includes a fixing member, a holding member, and a connecting member that connects these two types of members, and the fixing member and the holding member are movable in a fixed amount of displacement while being connected.

  Here, the fixing member has a fixing portion as a means for fixing to the fixing object and a holding portion as a means for holding the connecting member, and the clamping member contacts a fixed object that can be displaced by a certain amount. It can have a contact part as a means to do and a holding part as a means to hold | maintain a connection member. The connecting member is capable of connecting the fixing member and the holding member and forming a movable portion between the fixing member and the holding member in relation to the holding member and the holding member. The movable range can be set.

  The fixing member can have a contact portion as means for contacting a fixed object that can be displaced by a certain amount. Further, the means for contacting the object to be fixed can include means for fixing the object to be fixed. Therefore, the contact portion may also be used as the fixed portion. Moreover, the clamping member can also have a means fixed to a fixed target object. Such a fixture can be used at any displacement position regardless of the horizontal or vertical direction. Especially, it can absorb vibrations and shocks efficiently by using a fixture for vibration and shock absorption. Can be widely used in technical fields where

  The fixing member and the sandwiching member may be separate or integrated, but in the case of separate bodies, at least one of the fixing member and the sandwiching member includes a movable portion or a penetrating portion that allows the holding portion that holds the connecting member to move the connecting member. Can have. At this time, the movable part or the penetrating part is a groove, a long hole, a slit hole, etc., and by determining the length of the groove or hole, the upper limit and the lower limit of the movable width between the fixed member and the sandwiching member may be determined. I can do it.

  The fixing member and the holding member can have a substantially L-shaped cross section, and one end of each of the fixing member and the holding member is connected by a connecting member, and the other end of the fixing member and the holding member is opposed to each other, A space for an object to be fixed can be provided between these ends. In this case, a movable part and a movable range by the coupling member can be set for the coupling part of the fixing member and the clamping member, or alternatively, the tip of one end of the fixing member and the clamping member, particularly the upper part thereof and It is possible to determine the lower limit of the movable width by bringing at least one of the lower end portions into contact with a clamping member, an object to be fixed, a fixing member, an object to be fixed, a back surface of the object to be fixed, a plate material on the object to be fixed, etc. .

  When the fixed member and the holding member are integrated, the connecting portion, particularly the connecting member, may form a movable portion between the fixed member and the holding member, and itself moves between the fixed member and the holding member. Can be flexible. In addition, the holding portion can be made flexible. The flexible connecting portion, connecting member, or holding portion can be made of at least one of a slide member that can be expanded and contracted, such as an elastic body such as a spring, sponge, or rubber. In addition, the fixing jig has such a flexible connecting portion, holding portion or connecting member as a basic portion, and its end portion is reinforced with a reinforcing member or the like, thereby producing a portion corresponding to the fixing member and the clamping member. I can do it. The movable width between the fixed member and the sandwiching member can be set by the connecting member or other portions, or other fixed members and portions of the sandwiching members.

  The clamping member is connected to the fixing member so as to be movable, and has a contact portion that contacts a fixed object that can be displaced by a certain amount. The fixed object can be displaced by a certain amount between the contact part of the holding member and the object to be fixed or between the contact part of the holding member and the contact part of the fixing member. When the fixed object is compressed, the contact portion of the clamping member can serve as a pressing surface for the fixed object. The contact portion of the fixing member may be used as the fixing portion of the fixing member.

Embodiments of the present invention will be described in order from the materials used.
There are no particular restrictions on the object to be displaced. Typically, a shock absorber or the like is fixed to a face material. In this case, if the face material is a member that forms a flat surface on the shock absorber side, the fixed member side, or the clamping member side, the material and dimensions are particularly important. There are no restrictions. More specifically, in the case of a heavy floor impact sound improvement floor material, in the case of a joist or joist, etc., a soundproof floor in which a plurality of types of shock absorbers are arranged and fixed at an arbitrary interval on an elongated plate-like support material as a face material. The material is used as a displaceable fixed object. A plurality of such soundproofing floor materials are fixed on the floor slab at arbitrary intervals, and a floor base plate or the like is installed and fixed thereon. However, it is also possible to make a fixed object including the floor base plate and the like that can be displaced.

  Next, the fixing object is one in which the fixing jig is fixed and, as a result, the object to be fixed can be fixed, and is not particularly limited. Here, fixing of the fixing jig is not mainly a weak fixing strength such as adhesive, but a strong bonding, a physical fixing with a screw or a nail, or a combination of bonding and physical fixing. A material that provides a fixing strength that suppresses warpage of a plate material or the like is used. More specifically, the floor slab corresponds to the fixed object in the floor material for improving the heavy floor impact sound, the joist, the joist, and the like. Here, the floor slab includes not only the floor slab alone such as the ALC plate but also the case where the ALC plate is connected and integrated with the face material by providing the face material on the ALC plate. Include in the floor slab.

Next, the constituent materials for the fixing jig body will be described.
In the present invention, the fixing jig includes a fixing member, a sandwiching member, and a connecting member, and the fixing member and the sandwiching member may be separate members, and the connecting member is separated from the fixing member or the sandwiching member. Even if it is a thing, it may be a part of a fixing member or a clamping member.

  The fixing member only needs to have a fixing portion as a means for fixing to the fixing object itself and a holding portion as a means for holding the connecting member. In addition to the fixed part, the means to be fixed to the fixed object includes a screw or nail locking hole, an adhesive, etc. When applying the adhesive alone or in combination, The fixing member, particularly the surface of the fixing portion on the fixing object side, may be solidified and formed into a ball shape so as to increase the adhesive force. A single screw or nail hole may be used, but a plurality of types of holes are more effective in preventing rotation of the fixing member. The means for holding the connecting member includes a penetrating part for inserting and holding an independent connecting member, and the penetrating part may be a simple hole or a plurality of types of selectable holes between the fixing member and the holding member. A movable long hole or slit groove may be used. Also, the fixing member or the clamping member itself may have a connecting projection.

  The holding member is connected to the fixing member, has a means for holding the connecting member, and has a contact portion of the fixed object. The contact portion can act as a pressing portion for the fixed object. Here, the means for holding the connecting member may be a penetrating part for inserting and holding an independent connecting member, like the fixed member, and the penetrating part may be a simple hole or a movable hole or groove. However, it is preferable that either one or both of the fixing member and the holding member have a movable hole or groove. Further, the sandwiching member itself may be provided with a connecting projection and used as the connecting member. The contact part that can contact the fixed object is basically not particularly limited, but it is sufficient that there is a surface that can press the surface of the fixed object, for example, the soundproof flooring, and the stress to be pressed is effectively applied. The shape and dimensions are good.

  As described above, at least one holding portion of the fixing member and the clamping member is configured such that a predetermined amount of movable width is allowed between the fixing member and the clamping member at the connecting portion of the fixing member and the clamping member. It can have a through-hole of the connecting member.

  The movable direction of the fixing member and the clamping member may be at least one direction, may be two directions, three directions, and may be a plurality of directions as much as possible. The movable direction can be a direction orthogonal to the contact surface of the fixing member and the clamping member with respect to the fixed object or the fixed object.

  The holding portion of the fixing member and the holding member can form an opposing surface by the connecting portion of the fixing member and the holding member. At this time, at least one of the opposing surfaces of the fixing member and the holding member has a sliding assist. Materials can be provided.

  When the fixing member and the holding member are viewed in cross section in the movable direction, the moving direction of the fixing member may be perpendicular to the fixed surface of the object to be fixed, and the moving direction of the holding member is a presser of the displaceable object to be fixed. The direction perpendicular to the surface may be sufficient. At this time, each holding part of the fixing member and the holding member can form an opposing surface at the connecting part where the fixing member and the holding member are connected. At this time, in consideration of contact and sliding of the fixing member and the clamping member, the sliding auxiliary material is attached to at least one of the holding surfaces of both the fixing member and the clamping member, thereby fixing the fixing member. And the generation of noise between the clamping members is prevented, and the sliding becomes smooth.

  The sliding aid may be a film, a film, a sheet, or the like made of polyolefin such as polyethylene (PE) or polypropylene (PP), silicon, Teflon (registered trademark), or the like. These may be slit or cut off at the penetrating portion.

  In the present invention, as a method of determining the movable range of the fixed member and the holding member, it is possible to use the inherent displacement width of the displaceable fixed object. However, according to this means alone, the fixed object itself is the upper limit of the displacement width. And at the lower limit, it is irreversibly denatured, which may cause malfunction, breakage, or destruction. In such a case, it is preferable to use a means that enables displacement of the object to be fixed within the inherent movable range of the fixing jig and combines the inherent displacement performance of the object to be fixed.

  As described above, the movable range of the fixing jig, that is, the movable range of the fixing member and the holding member can be determined by the through hole of the connecting member, the connecting portion, particularly the connecting member itself, or the holding portion. As for the point where the tip of the holding part of the fixing member comes into contact with the holding member, in particular the contact part of the holding member, the tip of the holding part of the fixing member has an object to be fixed, especially the object to be fixed has a face material. In the case of a shock absorbing material having a face material, the point of contact with the back surface of the face material or the back surface of the face material laminated just above the object to be fixed, or the tip of the holding part of the holding member is fixed In some cases, the lower limit of displacement may be a point that comes into contact with an object, in particular its upper surface, or a penetrating part that becomes a movable part of a fixed member or a holding member, in particular, a point where a connecting member comes into contact with the lower end thereof. On the other hand, in some cases, the upper limit of the displacement can be determined by another member or the like. However, in the above-described fixing jig including the fixing member, the holding member, and the connecting member, the fixing member or the connecting portion of the holding member has a penetrating portion. In the case of forming the movable part by forming the upper limit, the upper limit of displacement can be determined particularly at the point where the connecting member comes into contact with the upper end of the penetration part. In any case, it is preferable that the tip of the holding portion of the fixing member does not protrude beyond the contact portion of the holding member, and the tip of the holding portion of the holding member hits the fixed object. It is good not to touch.

  Next, when performing screws and nailing that are physically fixed easily in construction, both the fixing member having a substantially L-shaped cross section and the clamping member are connected by a connecting member, and the fixing jig having a substantially U-shaped cross section is connected. When used as a tool, when the fixed member and the holding member are both connected by the connecting member and lifted to the upper limit of movement, the movable surface of the fixed member or the holding member is at the maximum displacement position of the fixed member and the holding member. However, even if the fixing member or the holding member is rotated by 90 °, the fixing member or the holding member does not come into contact with the holding member or the fixing member, and the fixing member or the holding member can freely rotate. The contact portion of the fixed object of the member can be easily attached to the fixing object or the like without closing the fixing hole to the fixing object or the like in the fixing member or the fixing portion of the fixing member. It can be fixed.

  Here, both the fixing member and the clamping member may be the same type or different from each other, and various modes are conceivable depending on how they are combined. As shown in the attached drawings and the detailed description thereof, four directions are conceivable, but this combination may be used and is not particularly limited. Since the joist effect can be exhibited at the outermost periphery of the floor and the restraint area can be minimized relative to the floor area, the method of using a vertical part at the outermost periphery with a substantially U-shaped fixing member has an adverse effect on sound performance. You can minimize it.

  In terms of construction, the fixing of the object to be fixed by the fixing jig is not particularly limited, and can be determined in various ways. In particular, in the case of soundproofing joist, It is not necessary to provide the entire length, and a fixing jig having a predetermined width may be used at a pitch of 300 to 900 mm.

  The material of the fixing jig including the fixing member, the clamping member, the connecting member, and the like is not particularly limited, but metal, plastic, and the like are suitable, and a laminate thereof may be used. In addition, when a desired design such as thickness is required, a surface material is provided on the object to be fixed, and in order to avoid the occurrence of unevenness in the holding part of the fixing jig, rubber, plastic, or their foam The unevenness may be eliminated by pasting.

The present invention will be described in more detail with reference to the drawings.

(Comparative Example 1)
After the measurement in Example 5, the soundproofing floor material in the center of Example 1 was disassembled and the soundproofing flooring material and the fixing jig around the floor outer periphery were removed, and only the soundproofing flooring material used in Example 1 was removed. The floor is installed on the floor slab of the outer periphery of the floor, and the structure on the soundproof flooring is assembled in the same manner as in the first embodiment, and the weight impact sound is measured in the same manner as in the first embodiment. The results are shown in Table 1.

(Comparative Example 2)
After the measurement in Comparative Example 1, the soundproofing floor material in the center of Example 1 was disassembled to the state where it was installed, and only the soundproofing flooring material used in Example 1 was mounted on the floor slab around the floor outer periphery. At the bottom, a piece of 455 mm pitch 8.5 mm thick x 40 mm wide x 50 mm long vulcanized rubber with a piece of wood 17 mm thick x 40 mm wide x 50 mm long is installed, and the soundproof flooring is on the support plate The screw is fixed to the particle board of the floor slab to prevent both rising and sinking. As for the structure on the soundproof floor material, the floor is assembled in the same manner as in the first embodiment, and the heavy floor impact sound is measured in the same manner as in the first embodiment. The results are shown in Table 1.

The effect of this invention is demonstrated based on an Example and a comparative example.
In Comparative Example 1, the soundproofing floor material on the outer periphery of the floor is a floor that does not have any means for controlling the amount of floor displacement even when the floor is lifted or submerged due to a load. There is a certain limit to the performance of soundproofing. However, this example is a floor where the heavy floor impact sound does not deteriorate due to the control of the floating and sinking of the floor. On the other hand, Comparative Example 2 is different from Comparative Example 1 in that a so-called spacer in which a piece of wood and rubber are laminated around the circumference of the floor is placed at the lower part of the support plate of the soundproof floor material at a pitch of 455 mm and fixed to the particle board of the floor slab with screws. Yes, it prevents the floor from rising and does not sink below the spacer, but the shock absorbing material is fixed by penetration with screws. As a result, in Comparative Example 2, compared to Comparative Example 1, 63Hz in deterioration of 3.1dB can be seen, L _H value is also to 3dB worse. Deterioration of 3 dB in the L _H value is large, and it is considered that the L _H 55 grade may not be obtained depending on the building.

Compared with Comparative Example 1, Example 1 shows almost no deterioration. That is 0 dB 0.2 dB, at L _H value at 63 Hz, deterioration degree in any other frequency is less than 1dB. The difference between Comparative Example 1 and Example 1 is whether or not a fixing jig is provided around the floor outer periphery. It can be said that the fixing jig used here does not deteriorate the weight impact sound. In addition, the fixed jig | tool of Example 1 controls a movable range only by a penetration long hole and a connection part.

It can be seen that Example 2 hardly deteriorates as compared with Comparative Example 1. 0.4dB at 63 Hz, a 0dB at L _H value, deterioration degree at other frequencies is 1dB or less. The difference between Comparative Example 1 and Example 2 is that Example 2 is provided with a fixing jig and there is floor displacement control, and it is understood that there is almost no deterioration of heavy floor impact sound.

Example 3, compared with Comparative Example 1, 1.3 dB at 63 Hz, 1.0 dB at 125 Hz, 1.2 dB at 250 Hz, 500 Hz at 1.2 dB, although L _H value is 1dB worse, the control of the displacement of the floor displacement Although it attached, it turns out that a deterioration degree is very low compared with the comparative example 2. The third embodiment is an example in which a long hole and a connecting portion are used as the upper limit, and the upper end portion in the movable direction of the fixed member and the lower end portion in the movable direction of the clamping member are used as the lower limit as floor displacement control.

Worse Example 4 as compared to Comparative Example 1, 1.0 dB at 63 Hz, 0.6 dB at 125 Hz, 0.8 dB at 250 Hz, 500 Hz at 0.8 dB, is a 1dB deterioration in L _H value, because it has a control of the floor displacement The degree is very low. In the determination of the movable range of the fixing jig used here, the upper limit is the elongated hole and the connecting portion, and the lower limit is the lower end of the holding member moving direction.

Example 5 as compared to Comparative Example 1, 1.2 dB at 63 Hz, 0.7 dB at 125 Hz, 0.5 dB at 250 Hz, 500 Hz at 0.4 dB, is a 1dB deterioration in L _H value, a control of the floor displacement These values of are good. In the determination of the movable range of the fixing jig used here, the upper limit is the slit groove and the connecting portion, and the lower limit is the lower end of the holding member moving direction.

  From the above, if the fixing jig of the present invention is used, even if an upper limit and a lower limit are provided for the floor displacement due to the soundproof flooring material, no deterioration to heavy sound is observed.

  The fixing jig of the present invention can stably exhibit good vibration-proofing performance and shock absorption performance of the object to be fixed in a controlled state, and prevent the vibration-proofing base of the washing machine and the car from being damaged. It can also be used for car stops.
