Description

[Technical Field]

[0001] The present invention relates to a mounting device, and more particularly to a mounting device that can absorb vibrations generated in a mounting member attached to a roof, thereby suppressing the transmission of vibrations from the mounting member to the roof. [Background technology]

[0002] Traditionally used as roofs for buildings such as factories and warehouses, corrugated roofs have recently begun to be adopted for offices, stores, and other buildings due to their cost benefits, and there is a growing demand for them to provide a good indoor environment in terms of quietness and temperature.

[0003] For example, in order to reduce heating and cooling costs, double-layered corrugated roofs consisting of an upper and lower layer are becoming widely used. However, with double-layered corrugated roofs, there is a risk that vibrations such as noise caused by thermal expansion and contraction of the corrugated roofs may occur, which could disrupt the quietness of the room.

[0004] As a measure to reduce vibrations such as noise caused by thermal expansion and contraction, for example, as disclosed in Patent Document 1, mounting fixtures have been developed that have a sliding mechanism that allows the roof material to slide relative to the mounting fixture.

[0016] The mounting device of the present invention is a mounting device for mounting a mounted member on a roof, and prevents vibrations such as noise caused by thermal expansion and contraction from being transmitted to the roof by absorbing them with a vibration-absorbing material. The vibration-absorbing material has a structure in which a vibration-damping composition is contained in a resin porous substrate including a nonwoven fabric.

[0017] Therefore, the mounting device of the present invention only needs to comprise at least a device body that is fixed to the roof and supports the workpiece, and a vibration-absorbing member attached to the device body so as to be interposed between the device body and the roof, and / or a second vibration-absorbing member interposed between the workpiece and the device body. Here, the vibration-absorbing member may be any member that contains a vibration-damping composition in a porous resin substrate that includes a nonwoven fabric.

[0018] Furthermore, the structure of the roof on which the mounting device of the present invention is used and the member to be mounted on the roof are not particularly limited. For example, the roof may have a double-roofed structure, or may be a platform for mounting multiple roof-mounted pieces of equipment such as multiple solar panels and multiple antennas.

[0019] In the following description of the embodiments, as an example, the roof is a double-layered folded-plate roof with a seam. The mounting fixture may be, for example, an insulating metal fitting made up of a combination of an insulating part and a metal part. Hereinafter, the embodiments of the present invention will be described with reference to the drawings.

[0020] (Embodiment 1) First, a typical example of a roof structure to which the mounting device of the present invention is applied will be briefly described.

[0021] [Roof structure 1] FIG. 1 is a perspective view showing a double-layered seam-type folded-plate roof as an example of a double-layered folded-plate roof. The lower roof R1 is a metal roof formed by arranging roofing materials R1a on a base material B of the building roof and joining the ends of adjacent roofing materials R1a. The joints (seam portions) S1 of adjacent roofing materials R1a are also joined to retaining clips H1 fixed to the apex of the tight frame Tf, and a mounting fixture 10 is further fixed to the seam portions S1. The ends of adjacent roofing materials R1a are joined to the retaining clips H1 by caulking.

[0022] The upper roof R2 is a metal roof formed by arranging roofing materials R2a on the lower roof R1 and joining the ends of adjacent roofing materials R2a. The joints S2 of adjacent roofing materials R2a are also joined to retaining clips H2 fixed to the top surface of the mounting fixture 10. The ends of adjacent roofing materials R2a and the retaining clips H2 are fixed by caulking.

[0023] Therefore, the roof structure 1 including the double-structured seam-type folded-plate roof R is composed of at least the roof base material B of the building, the tight frame Tf, the retaining clip H1, the lower roof R1, the mounting device 10, the retaining clip H2, and the upper roof R2.

[0024] [Mounting fixture 10] Fig. 2 is a perspective view showing a mounting device 10 according to embodiment 1 of the present invention. Fig. 3 is a plan view of the mounting device of embodiment 1 shown in Fig. 2 as viewed from each direction (arrows A1, B1, C1, D1, E1).

[0025] This mounting fixture 10 comprises a fixture body 100 fixed to a lower roof R1 and supporting an upper roof R2, and a vibration absorbing member 121 attached to the fixture body 100 so as to be interposed between the fixture body 100 and the lower roof R1.

[0026] In addition, the retaining clip H2 is placed on the insulating part 100c so that the fixing bolt Bf fixed to the other clamping piece 100b of the mounting fixture 10 is inserted into the bolt insertion hole H2f of the retaining clip H2, and the retaining clip H2 is fixed to the mounting fixture 10 by tightening the fixing nut Nf onto the fixing bolt Bf.

[0027] In this way, the mounting fixture 10 is fixed to the seam S1 of the lower roof R1, and the retaining clip H2 is attached to the mounting fixture 10. Then, the roof material R2a of the upper roof R2 is fixed to the retaining clip H2 by caulking. This completes the upper roof R2 of the two-layer folded-plate roof R. A second vibration absorbing member 122 is provided at one head portion 110c and the other head portion 120c of the heat insulating member 100c, which is located at the top of the appliance body 100. In addition, a second vibration absorbing member 122 is provided on the surface of the retaining clip H2 that faces the tool body 100. In this embodiment, a case has been presented in which vibration absorbing members are provided on the bottom surface portions 120a, 120b of the clamping pieces that come into contact with the lower roof R1 of the fixture body 100, on one head 110c and the other head 120c of the insulating member 100c, and on the surface of the retaining clip H2 that faces the fixture body 100, but it is also possible to select one or two of these and provide them. In addition, in embodiment 1, the retaining clip is shown to have a structure in which the retaining clip does not move relative to the mounting fixture when attached to the mounting fixture, but the retaining clip may also have a structure in which the retaining clip can move relative to the mounting fixture when attached to the mounting fixture so that thermal distortion of the upper roof R2 can escape.

[0028] [Apparatus body 100] The fixture body 100 includes a pair of clamping pieces 100a and 100b that clamp the seam S1 of the lower roof R1, a clamping member that clamps the pair of clamping pieces 100a and 100b so that the pair of clamping pieces 100a and 100b clamp the seam S1, and a heat insulating member 100c that blocks heat transfer from the upper roof R2 to the lower roof R1. The pair of clamping pieces 100a and 100b are metal plates made of iron or stainless steel, and the heat insulating member 100c is a resin product. The clamping members are a clamping bolt Bt and a clamping nut Nt.

[0029] One of the clamping pieces 100a has a clamping piece bottom 120a, a clamping piece main body 110a attached to the clamping piece bottom 120a, and a clamping piece upper surface 130a formed to cover the upper side of the clamping piece main body 110a. A first vibration absorbing member 121 is attached to the back surface of the clamping piece bottom 120a. A rear opening 101a is formed in the lower part of a rear wall 111a of the clamping piece main body 110a, and this rear opening 101a forms a space 101 for accommodating the seam portion. Furthermore, an upper contact plate 103 is formed in the upper part of the rear wall 111a, and a lower contact plate 102 is formed in the lower part of the rear wall 111a.

[0030] The other clamping piece 100b also has a clamping piece bottom portion 120b, a clamping piece main body 110b attached to the clamping piece bottom portion 120b, and a clamping piece upper surface portion 130b formed to cover the upper side of the clamping piece main body 110b. A first vibration absorbing member 121 is attached across from the back surface of the clamping piece bottom portion 120b to the lower part of the rear wall 111b of the clamping piece main body 110b. A fixing bolt Bf for fixing other components to the other clamping piece 100b is fixed by welding to the clamping piece upper surface portion 130b.

[0031] In such an instrument body 100, when a pair of clamping pieces 100a and 100b are tightened, the upper abutment plate 103 of one clamping piece 100a abuts against the back wall 111b of the other clamping piece 100b, and the lower abutment plate 102 of one clamping piece 100a presses the flap portion S1 against the back wall 111b of the other clamping piece 100b.

[0032] The insulating component 100c has a first head portion 110c positioned on one clamping piece 100a so as to be slidable relative to the clamping piece 100a, a second head portion 120c placed on the other clamping piece 100b so as to be supported by the other clamping piece 100b, and a body supporting these head portions. The first head portion 110c, the second head portion 120c, and the body are integrally formed. A fixing bolt hole Hf is formed in the second head portion 120c, and a tightening bolt hole (not shown) is formed in the body.

[0033] [Vibration absorbing member] The vibration absorbing members include a first vibration absorbing member 121 installed between the lower roof R1 and the mounting fixture 100, and a second vibration absorbing member 122 installed between the mounting fixture 100 and the retaining clip H2 and between the retaining clip H2 and the upper roof R2. The first vibration absorbing member 121 and the second vibration absorbing member 122 absorb vibrations generated in the upper roof R2, thereby suppressing transmission of vibrations from the fixture body 100 to the lower roof R1. These vibrations are noises and other vibrations caused by thermal expansion and contraction of the upper roof R2 due to solar radiation. The first vibration absorbing member 121 and the second vibration absorbing member may be made of the same material and composition, or may be made of different materials and compositions. The first vibration absorbing member 121 and the second vibration absorbing member may be installed simultaneously, or only one or both may be selected and used.

[0034] The vibration absorbing material (first and / or second vibration absorbing member) may have any structure or form as long as it contains a composition that exhibits a vibration-damping effect by absorbing vibrations. Preferably, it is a porous resin substrate containing a nonwoven fabric impregnated with a vibration-damping composition. Also, known, commercially available compositions that exhibit a vibration-damping effect may be used.

[0035] The resin porous substrate may be made of any material and in any form as long as it is made of resin and forms a porous material, for example, nonwoven fabric or foamed plastic.

[0036] In addition, foamed plastics can be produced using a known foaming method using a thermoplastic resin or a thermosetting resin as a raw material. The specific composition of the thermoplastic resin and the thermosetting resin is not limited. Known or commercially available materials can be used.

[0037] The vibration-absorbing material of the present invention is produced by impregnating a porous resin substrate containing a nonwoven fabric with the vibration-damping composition described above.

[0038] If necessary, the vibration absorbing member may be made up of two or more layers to which a member harder than the resin porous substrate, such as a metal member or a ceramic member, is attached.

[0039] Next, the work of attaching the upper roof R2 onto the lower roof R1 using the attachment tool 100 of the first embodiment will be described.

[0040] Figure 4 shows the process of attaching an upper roof to a lower roof using the attachment tool shown in Figure 2. As shown in Figure 4(a), the lower roof R1 is constructed by overlapping and bending the ends of adjacent roofing materials R1a to join them. At the joint Sc between the seam S1 of the lower roof R1 and the retaining clip H1, the retaining clip H1 and the adjacent roofing material R1a are fixed by caulking.

[0041] Here, the retaining clip H1 is fixed to the tight frame Tf with fasteners Fs such as bolts and nuts, and the tight frame Tf is attached to the base material B of the roof of the building or the like.

[0042] The upper roof R2 of the two-layer seam-type folded-plate roof is formed by fixing the mounting fixture 10 to the lower roof R1, fixing the retaining clip H2 to the fixing bolt Bf of the mounting fixture 10 with a nut Nf, and then fixing the roof material R2a to the retaining clip H2, as shown in Figure 4(b).

[0043] The fixing operation of the mounting fixture 10 and the fixing operation of the retaining clip H2 will now be briefly described.

[0044] Figure 5 is a diagram showing the work procedure for attaching the mounting fixture 10 to the lower roof R1 and the upper roof R2, and shows the state in which the mounting fixture is ready to be attached to the corrugated roof (Figure 5(a)), the state in which the mounting fixture is fixed to the lower roof (Figure 5(b)), and the state in which the upper roof is fixed to the mounting fixture (Figure 5(c)).

[0045] The clamping nut Nt of the mounting fixture 10 is loosened to create a gap Sp large enough for the seam S to pass between the pair of clamping pieces 10a and 10b (FIG. 5(a)). The mounting fixture 10 is then attached to the seam S1 of the lower roof R1, and the clamping nut Nt and the clamping bolt Bt are tightened so that the pair of clamping pieces 100a and 100b of the mounting fixture 10 clamp the neck of the seam S1 (FIG. 4(b)). This secures the mounting fixture 10 to the seam S1 of the lower roof R1. In this state, the first vibration-absorbing members 121 attached to the back surfaces of the clamping piece bottoms 120a and 120b of the clamping pieces 100a and 100b are pressed against the back surfaces of the clamping piece bottoms 120a and 120b and the top surface of the lower roof R1. Then, the retaining clip H2 is placed on the second vibration absorbing member 122 attached to the insulating part 100c with the surface opposite to the surface on which the second vibration absorbing member 122 is attached facing the mounting device 10 so that the fixing bolt Bf fixed to the other clamping piece 100b of the mounting device 10 is inserted into the bolt insertion hole H2h of the retaining clip H2, and the fixing nut Nf is tightened onto the fixing bolt Bf to fix the retaining clip H2 to the mounting device 10 (Figure 5(c)).

[0046] In this way, the mounting fixture 10 is fixed to the seam S1 of the lower roof R1, and the retaining clip H2 is attached to the mounting fixture 10. Then, the roof material R2a of the upper roof R2 is fixed to the retaining clip H2 by caulking. This completes the upper roof R2 of the two-layer folded-plate roof R.

[0047] As described above, by installing the vibration absorbing member of the present invention between the lower roof and the mounting fixture, and between the mounting fixture and the upper roof or retaining clip, which is the fixture to be mounted, it is possible to effectively and reliably suppress vibrations such as noise caused by thermal expansion and contraction of the upper roof from being transmitted to the lower roof. It is clear that the placement location of the vibration absorbing member (second vibration absorbing member) can be selected based on the required vibration damping conditions.

It is understood that the scope of the present invention should be interpreted only by the claims.
