Abstract
Description
Technical Field
[0001] The present invention relates to a cover for a suspended pipe support, and more particularly to a cover for a suspended pipe support used for a suspended pipe support including a suspension bolt, a turnbuckle, and a fastening member.
Background Art
[0002] Conventionally, a suspended pipe support has been used as a support for suspending and supporting a pipe from a ceiling surface or the like. A pipe suspended by a suspended pipe support is provided with a heat insulating material in order to ensure heat insulation and cold insulation properties. Construction methods and the like for providing a heat insulating material on a pipe are prescribed in advance by standards for heat insulation and cold insulation work construction (JIS A9501) and the like (see, for example, Non-Patent Document 1 and Non-Patent Document 2).
[0003] As standard construction methods for installing a heat insulating material on a pipe, there are known two types of methods: (1) a method using a synthetic resin support receiver, and (2) a method of covering the pipe with a cover member for heat insulation and cold insulation. The method using a synthetic resin support receiver is a method of realizing a heat insulation and cold insulation effect in a pipe by interposing a heat insulating material made of resin (for example, urethane foam) having a cylindrical shape between the pipe and a suspension band that holds the outer periphery of the pipe.
[0004] The method of covering a pipe with a cover member for heat insulation and cold insulation is a method of realizing a heat insulation and cold insulation effect of the pipe by covering the outside of the pipe using a cover member in which an inner groove corresponding to the outer shape of the pipe is formed (see, for example, Patent Documents 1 to 3). When covering a pipe with a cover member, generally, the pipe is covered including the suspension band of the suspended pipe support that suspends the pipe.

Summary of the Invention
Problems to be Solved by the Invention
[0007] Here, in order to achieve the heat insulation and cold insulation effects in piping, it is preferable to take heat insulation and cold insulation measures not only for the piping but also for the suspended piping supports that support the piping. In particular, when covering the piping with a cover member for heat insulation and cold insulation, since an annular fitting of a suspension band is attached to the outer periphery of the piping, there is a risk that the temperature of the suspended piping support is transmitted to the piping through the annular fitting, affecting the temperature state of the piping.
[0008] When taking heat insulation measures for the suspended piping support, generally, after winding a strip-shaped heat insulation sheet (strip-shaped foam) around the outside of the suspended piping support, the heat insulation sheet is fixed to the suspended piping support using tape or the like, and the gap between the suspended piping support and the heat insulation sheet is blocked using a heat insulation sheet or tape cut to an appropriate size.
[0009] Here, since the suspended piping support is suspended from the ceiling surface, it is necessary to perform the operation of winding the heat insulation sheet around the suspended piping support while holding the end of the heat insulation sheet with one hand and placing the hand on the suspended piping support, and further fixing the wound heat insulation sheet with tape or the like. For this reason, there has been a problem that the attachment work of the heat insulation sheet is difficult.
[0010] In addition, when attaching a heat-insulating sheet to a suspended pipe support using a heat-insulating sheet and tape or the like, the quality of the attachment of the heat-insulating sheet depends greatly on the skill of the operator, resulting in a problem that the heat-insulating and cold-insulating effects on the suspended pipe support vary.
[0011] Furthermore, since it is necessary to fix the heat-insulating sheet to the suspended pipe support with both hands raised, there is also a problem that the work burden is heavy due to the difficulty of attaching the heat-insulating sheet.
[0012] The present invention has been made in view of the above problems, and an object thereof is to provide a cover for a suspended pipe support capable of improving the workability for taking heat-insulating and cold-insulating measures against the suspended pipe support.

Embodiments for Carrying Out the Invention
[0020] Hereinafter, the cover for the hanging pipe support according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing a general hanging pipe support to which the cover for the hanging pipe support is attached, and FIG. 2 is a side view. The hanging pipe support 100 is a support for suspending and arranging a pipe with respect to a ceiling surface by suspending the pipe 300.
[0021] The hanging pipe support 100 is generally composed of a suspension bolt 110 with the tip of the shaft portion fixed to the ceiling surface, a turnbuckle 120 locked to the suspension bolt 110, a hanging band 130 attached to the pipe 300 so as to surround the outer periphery of the pipe 300, and fastening members 140 (bolt (fastening bolt) 141, nut (fastening nut) 142) for fixing the hanging band 130 to the turnbuckle 120.
[0022] The suspension bolt 110 has its head 112 facing downward and the tip of the shaft portion 113 facing the ceiling direction, and the tip of the shaft portion 113 is fixed to the ceiling surface. A thread 114 is formed on the shaft portion 113, and a nut (suspension nut) 115 that engages with the thread 114 can be attached to the shaft portion 113 of the suspension bolt 110.
[0023] The turnbuckle 120 is formed by bending a metal strip-shaped (plate-shaped) member (metal piece), and is integrally formed by an inverted triangular portion (inverted triangular shape portion) 121 formed in a substantially inverted triangular shape in a front view, and legs 122, 122 obtained by extending both ends of the strip-shaped member parallel to each other directly downward. The turnbuckle 120 has a substantially Y-shaped (left-right symmetric) shape in a front view, and an opening 123 for introducing an engagement protrusion or the like (engagement convex portion) described later into an internal space (second internal space) S1 is formed inside the inverted triangular portion 121. An upper hole 125 for locking the head 112 of the suspension bolt 110 is formed in the ceiling surface 124 of the inverted triangular portion 121. The upper hole 125 has an inner diameter larger than the shaft diameter (outer diameter, diameter) of the shaft portion 113 of the suspension bolt 110 and smaller than the outer diameter (diameter) of the head 112.
[0024] In the ceiling face 125, the shaft portion 113 of the suspension bolt 110 is inserted from the lower side to the upper side of the ceiling face 124, and the head portion 112 is locked to the lower face of the ceiling face 124 via the washer 116. In such a state, by screwing the nut 115 onto the shaft portion 113 of the suspension bolt 110, the inverted triangular portion 121 (more specifically, the ceiling face 124 of the inverted triangular portion 121) of the tumble 120 can be fixed (locked) to the suspension bolt 110 by the head portion 112 and the nut 115 of the suspension bolt 110. Further, the leg portions 122, 122 are respectively provided with penetration holes (leg holes) 126, 126 for penetrating the shaft portion 141a of the bolt 141 of the fastening member 140.
[0025] The suspension band 130 includes a first holding portion 133 and a second holding portion 134 having inner peripheral surfaces 131, 132 following the outer peripheral surface 301 of the pipe 300 and presenting a pair of split cylinder shapes. The first holding portion 133 and the second holding portion 134 are each formed by bending a metal strip-shaped member, and the lower end portions 133a, 134a thereof are connected by an assembled structure. The assembled structure means that the lower end portions 133a, 134a of the first holding portion 133 and the second holding portion 134 are comb-shaped, and by inserting the comb tip portion of the other into the gap between them, the first holding portion 133 and the second holding portion 134 are detachably attached. Note that the connection structure between the first holding portion 133 and the second holding portion 134 is not limited to the assembled structure, and may be connected so as to be rotatable via a hinge (hinge).
[0026] Furthermore, locking pieces 135, 136 that abut against the leg portions 122, 122 of the tumble 120 are integrally formed on the upper end portions 133b, 134b of the first holding portion 133 and the second holding portion 134, respectively. Penetration holes (band holes) 135a, 136a for penetrating the bolt 141 of the fastening member 140 are formed in the locking pieces 135, 136.
[0027] As described above, the fastening member 140 is composed of a bolt 141 and a nut 142. The shaft portion 141a of the bolt 141 is inserted horizontally into the penetration holes 126, 126 provided in the leg portions 122, 122 of the tumble 120 and the penetration holes 135a, 136a provided in the locking pieces 135, 136 of the suspension band 130, and the nut 142 is screwed onto the shaft portion 141a. Thus, the bolt 141 (the head portion 141b of the bolt 141) and the nut 142 fasten and fix the leg portions 122, 122 of the tumble 120 and the locking pieces 135, 136 of the suspension band 130. By the fastening and fixing with the fastening member 140, the suspension band 130 is fixed to the tumble 120.
[0028] FIG. 3 is a front partial cross-sectional view showing the suspension pipe support 100 and the suspension pipe support cover 200 attached so as to cover the outer periphery of the pipe 300 and the suspension pipe support 100, and FIG. 4 is a side partial cross-sectional view. In FIG. 3, the suspension pipe support cover 200 and the pipe 300 are shown in a cross-sectional view, and in FIG. 4, only the suspension pipe support cover 200 is shown in a cross-sectional view.
[0029] The suspension pipe support cover 200 is formed integrally with a substantially bell-shaped upper portion 211a, 241a having an internal space (first internal space) S2 capable of accommodating the suspension pipe support 100 therein and a cylindrical lower portion 211b, 241b covering the outer periphery of the pipe 300. As shown in FIG. 5, the suspension pipe support cover 200 is composed of a first cover 210 and a second cover 240 that are vertically divided along the extending direction of the pipe 300 and are symmetric about the left and right, and the lowermost portions of the first cover 210 and the second cover 240 are connected. For convenience of explanation, the connecting portion is referred to as a connecting portion 220. The suspension pipe support cover 200 can be opened and closed in the left-right direction with the connecting portion 220 as a reference. The suspension pipe support cover 200 is formed of a foam that has excellent heat insulation properties as described later, is elastically deformable by a pressing force, and can return to its original shape when the pressing force is removed (has an elastic restoring force).
[0030] The internal space S2 formed in the upper portions 211a and 241a of the cover 200 for the hanging pipe support has a size capable of accommodating at least the hanging bolt 110, the turnbuckle 120, the locking pieces 135 and 136 of the hanging band 130, and the fastening member 140. On the inner wall surfaces 221a and 221b of the upper portions 211a and 241a of the cover 200 for the hanging pipe support, as will be described later, engaging protrusions, engaging convex portions or engaging concave portions (nut engaging concave portion, head engaging concave portion, shaft engaging concave portion) for engaging the first cover 210 or the second cover 240 of the cover 200 for the hanging pipe support with any part of the hanging pipe support 100 are formed. The engaging protrusions, engaging convex portions and engaging concave portions will be described later.
[0031] Next, the foam constituting the cover 200 for the hanging pipe support will be described in detail. The foam constituting the cover 200 for the hanging pipe support is a molded product made of a material having elasticity and flexibility such as a polyolefin-based resin foam. The polyolefin-based resin foam is obtained by foaming a resin composition mainly composed of a polyolefin-based resin, and is widely used in applications where heat insulation, cold insulation, heat insulation, buffering, cushioning, etc. are required, such as heat insulating materials for pipes of air-conditioning equipment, heat insulating materials for preventing freezing of water pipes, heat insulating materials for roofs, various mats, and automobile interior materials.
[0032] Examples of the polyolefin-based resin include homopolymers or copolymers of olefin-based hydrocarbons, such as polyethylene, polypropylene, ethylene-propylene copolymer, copolymers of ethylene with α-olefins such as butene and pentene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-acrylic acid ester copolymer, ethylene-styrene copolymer, ethylene-propylene-styrene-butadiene copolymer, ethylene-vinyl chloride copolymer, and mixtures of two or more of these. These olefin-based resins may be chemically modified such as grafting. In addition, other thermoplastic resins such as thermoplastic elastomers, antioxidants, lubricants, colorants, deodorants, antistatic agents, flame retardants, and other various additives can be added to the polyolefin-based resin foam within a range not exceeding 50% by mass of the resin composition, if necessary.
[0033] The polyolefin resin foam used in the hanging pipe support cover 200 may be crosslinked or not, but crosslinked foam is preferably used because the cell diameter is small and the heat resistance is high. Crosslinking can be performed by a conventional method such as crosslinking with an electron beam or crosslinking with a peroxide. When the polyolefin resin foam is used as a crosslinked foam, the gel fraction is 10 to 70%, preferably 10 to 40%. A gel fraction of less than 10% is not preferred because the cell diameter is large and the heat resistance is low.
[0034] The cells of the polyolefin resin foam used in the hanging pipe support cover 200 may be either closed or open cells, but closed cells are preferred. Closed cells refer to cells formed in the synthetic resin that exist independently and do not allow air to pass between adjacent cells. In contrast, open cells refer to cells that have holes in the walls between adjacent cells, allowing air to pass between them. Closed cells are preferred when vacuum molding is performed or to prevent the intrusion of air or water.
[0035] The apparent density of the polyolefin resin foam used in the hanging pipe support cover 200 is 20 to 200 kg / m 3 and preferably 25 to 50 kg / m 3 The apparent density is 20 kg / m 3 If the apparent density is less than 200 kg / m, the mechanical properties such as compressive strength and elongation may be reduced, resulting in insufficient heat insulating performance and processing characteristics. 3 If the temperature exceeds this range, the insulation performance will be significantly reduced and the required temperature characteristics for keeping the temperature hot or cold may not be satisfied.
[0036] The 25% compression hardness of the polyolefin resin foam used for the cover 200 of the hanging pipe support is 200 kPa or less, preferably 100 kPa or less, and more preferably 50 kPa or less. When the 25% compression hardness of the polyolefin resin foam exceeds 200 kPa, the engaging protrusions, engaging convex portions, and engaging concave portions described below and the hanging pipe support 100 will not engage properly (the fit will be poor), which is not preferable.
[0037] The thermal conductivity of the polyolefin resin foam used for the cover 200 of the hanging pipe support is 0.043 W / m·K or less, preferably 0.039 W / m·K or less. For example, when used as a heat insulating material, if the thermal conductivity exceeds 0.043 W / m·K, it is not preferable.
[0038] The water absorption of the polyolefin resin foam used for the cover 200 of the hanging pipe support is 2.0 g / 100 cm 2 or less, preferably 1.5 g / 100 cm 2 or less, and more preferably 1.0 g / 100 cm 2 or less. This water absorption refers to the value measured in accordance with the method (A) of not wiping in JIS standard A9511 (2017) "Foamed Plastic Thermal Insulation Material 6.14". For example, when used as a heat insulating material, if the water absorption is greater than 2.0 g / 100 cm 2 it is not preferable because the heat insulating performance will be impaired by the absorbed water.
[0039] The polyolefin resin foam used for the cover 200 of the hanging pipe support may be used as a single layer of the foam, but a plurality of polyolefin resin foams with different thicknesses and compositions can be laminated. There is no particular limitation on the lamination method, and conventionally known methods such as adhesion and fusion can be used.
[0040] The polyolefin-based resin foam used for the cover 200 of the hanging pipe support can have a film, sheet, non-woven fabric, fabric, foam molded product, etc. mainly composed of polyolefin, PVC, polyester, urethane, nylon, rubber, metal, paper, etc., which have characteristics such as heat resistance, flame retardancy, weather resistance, water absorption, and flexibility laminated on at least one surface. There is no particular limitation on the lamination method, and conventionally known methods such as adhesion and fusion bonding can be used.
[0041] Next, the engaging protrusions, engaging convex portions, and engaging concave portions formed on the inner wall surfaces 221a and 221b of the cover 200 for the hanging pipe support will be described. On the inner wall surfaces 221a and 221b of the cover 200 for the hanging pipe support shown in FIGS. 3 to 5, engaging protrusions (engaging convex portions) 250a, 250b, 250c, and 250d that engage with the buckle 120 are provided. The engaging protrusions 250a, 250b, 250c, and 250d are in a state of being raised so as to have a gentle mound shape with respect to the inner wall surfaces 221a and 221b.
[0042] Since the buckle 120 is formed by bending a metal strip-shaped member, the internal space S1 formed in the inverted triangular portion 121 is a space communicating in the extending direction of the pipe 300 through the openings 123 and 123 formed by the edges of the inverted triangular portion 121. On the inner wall surface 221a of the first cover 210 facing the internal space S1 through the openings 123 and 123 the engaging protrusion 250a and the engaging protrusion 250b are provided so as to face each other with their tips facing the internal space S1. Further, on the inner wall surface 221b of the second cover 240 facing the internal space S1 through the openings 123 and 123, the engaging protrusion 250c and the engaging protrusion 250d are provided so as to face each other with their tips facing the internal space S1.
[0043] Further, on the ceiling portions of the inner wall surface 221a of the first cover 210 and the inner wall surface 221b of the second cover 240, groove portions 251a and 251b through which the shaft portion 113 of the suspension bolt 110 passes are formed, and engaging recesses (nut engaging recesses) 252a and 252b corresponding to the outer shapes of the shaft portion 113 and the nut 115 are formed. For the sake of convenience in explanation, this engaging recess is referred to as the first engaging recess.
[0044] When attaching the cover 200 for the suspended pipe support to the suspended pipe support 100 and the pipe 300, first, as shown in FIG. 5, the suspended pipe support 100 is introduced into the internal space S2 of the first cover 210, and the shaft portion 113 of the suspension bolt 110 is fitted into the groove portion 251a of the first cover 210, and the nut 115 is arranged to be fitted into the first engaging recess 252a, thereby positioning the cover 200 for the suspended pipe support with respect to the suspended pipe support 100. Further, when introducing the suspended pipe support 100 into the internal space S2 of the first cover 210, the engaging protrusions 250a and 250b provided on the first cover 210 are guided inside the opening 123 over the edge of the inverted triangular portion 121, thereby guiding them into the internal space S1.
[0045] As already described, the cover 200 for the suspended pipe support has elasticity, so the engaging protrusions 250a to 250d can also elastically deform to overcome the edge of the inverted triangular portion 121, and after overcoming the edge, it is possible to restore the shapes of the engaging protrusions 250a to 250d in the internal space S1 inside the opening 123.
[0046] In this way, by attaching the first cover 210 to the hanging pipe support 100, as shown in FIG. 5, it becomes possible to position and temporarily fix the first cover 210. After attaching the first cover 210 to the hanging pipe support 100, by moving the second cover 240 toward the hanging pipe support 100 via the connecting portion 220, in the same manner as the first cover 210, the hanging pipe support 100 is introduced into the internal space S2 of the second cover 240, and the shaft portion 113 of the hanging bolt 110 is fitted into the groove portion 251b of the second cover 240, and the nut 115 is fitted into the first engaging recess 252b. Further, the engaging protrusions 250c and 250d provided on the second cover 240 can be guided into the internal space S1 by overcoming the edge of the inverted triangular portion 121.
[0047] First, by positioning and temporarily fixing the first cover 210, the cover 200 for the hanging pipe support is prevented from easily coming off or falling from the hanging pipe support 100. For this reason, the attachment of the first cover 210 to the hanging pipe support 100 is simplified, and the first cover 210 can be securely attached to the hanging pipe support 100.
[0048] Also, after positioning and temporarily fixing with the first cover 210 in this way, by attaching the second cover 240 to the hanging pipe support 100, it becomes possible to securely and accurately attach the cover 200 for the hanging pipe support to the hanging pipe support 100 without being affected by the skill of the operator. Further, by using the engaging protrusions 250a to 250d and the first engaging recesses 252a and 252b, the positioning of the first cover 210 and the attachment of the second cover 240 can be easily performed, so that the attachment burden on the operator can be reduced. Finally, by the operator closing the boundary between the first cover 210 and the second cover 240 with tape or the like, it is possible to prevent gaps or the like from remaining in the cover 200 for the hanging pipe support, and it becomes possible to ensure higher heat insulation and cold insulation properties.
[0049] FIG. 6 is a view showing a case where the connecting portion 220 is provided at the uppermost part of the first cover 210 and the uppermost part of the second cover 240 in the cover 200 for the hanging pipe support shown in FIGS. 3 to 5. As shown in FIG. 6, even when the connecting portion 220 is provided at the uppermost part of the first cover 210 and the uppermost part of the second cover 240, as described with reference to FIGS. 3 to 5, after the first cover 210 is attached (positioned and temporarily fixed) to the hanging pipe support 100, the second cover 240 can be pulled and attached to the hanging pipe support 100 via the connecting portion 220. Also in this case, the cover 200 for the hanging pipe support can be surely and accurately attached to the hanging pipe support 100 without being affected by the skill of the operator, and the attachment burden on the operator can be reduced.
[0050] FIG. 7 is a front partial cross-sectional view showing the hanging pipe support 100 and the cover 201 for the hanging pipe support when a synthetic resin support receiver 400 is interposed between the pipe 300 and the hanging band 130. The cover 201 for the hanging pipe support shown in FIG. 7 is different from the cover 200 for the hanging pipe support shown in FIGS. 3 to 5 in that the portions covering the pipe 300 (the lower portions 211b, 241b of the cover 200 for the hanging pipe support) are not provided.
[0051] The lower end portions (the bottom surfaces of the first cover 210 and the second cover 240) 211c, 241c of the cover 201 for the hanging pipe support are processed into a shape that allows the bottom surfaces (the lower end portions 211c, 241c) to be in contact with the outer surface of the synthetic resin support receiver 400 and the outer surface of the hanging band 130 when the cover 201 for the hanging pipe support is attached to the hanging pipe support 100. Therefore, when the cover 201 for the hanging pipe support is attached to the hanging pipe support 100, no gap is generated between the lower end portions (bottom surfaces) 211c, 241c of the cover 201 for the hanging pipe support and the synthetic resin support receiver 400 or the like, and the heat insulation effect and cold insulation effect by the cover 201 for the hanging pipe support can be sufficiently ensured.
[0052] Regarding the cover 201 for the hanging pipe support tool as well, similar to the cover 200 for the hanging pipe support tool, engaging protrusions 250a, 250b, 250c, 250d are provided on the inner wall surface 221a of the first cover 210 and the inner wall surface 221b of the second cover 240, and first engaging recesses 252a, 252b are provided. For this reason, as described with reference to FIGS. 3 to 5, after the first cover 210 is attached (positioned and temporarily fixed) to the hanging pipe support tool 100, the second cover 240 can be pulled and attached to the hanging pipe support tool 100 via the connecting portion 220. Also in this case, the cover 201 for the hanging pipe support tool can be surely and accurately attached to the hanging pipe support tool 100 without being affected by the skill of the operator, and the attachment burden on the operator can be reduced.
[0053] FIG. 8 is a side view showing a cover 202 for a hanging pipe support tool in which the position where the connecting portion 220 is provided is different from that of the cover 201 for a hanging pipe support tool shown in FIG. 7. In the cover 202 for a hanging pipe support tool, the first cover 210 and the second cover 240 are connected by the connecting portion 220 at their respective side portions. Also in the cover 202 for a hanging pipe support tool, similar to the covers 200 and 201 for a hanging pipe support tool, engaging protrusions 250a, 250b, 250c, 250d are provided on the inner wall surface 221a of the first cover 210 and the inner wall surface 221b of the second cover 240, and first engaging recesses 252a, 252b are provided. For this reason, when attaching the cover 202 for a hanging pipe support tool to the hanging pipe support tool 100, after the first cover 210 is attached (positioned and temporarily fixed) to the hanging pipe support tool 100, the second cover 240 can be pulled and attached to the hanging pipe support tool 100 via the connecting portion 220. Also in this case, the cover 202 for a hanging pipe support tool can be surely and accurately attached to the hanging pipe support tool 100 without being affected by the skill of the operator, and the attachment burden on the operator can be reduced.
[0054] Next, the case where the shapes of the engaging protrusions are different will be described. FIGS. 9 to 14 are views showing covers for a hanging pipe support having engaging protrusions with shapes different from the engaging protrusions 250a to 250d provided on the covers 200 and 201 for a hanging pipe support shown in FIGS. 3 to 8. In the covers 203 and 204 for a hanging pipe support shown in FIGS. 9 to 13, engaging protrusions 253a to 253d having a reverse right-angled triangle shape in a front view are formed at positions where the engaging protrusions 250a to 250d were provided in the covers 200 and 201 for a hanging pipe support.
[0055] Each of the engaging protrusions 253a to 253d is provided at an end portion (position from the boundary) of the inner wall surfaces 221a and 221b of the first cover 210 and the second cover 240. In a state where the first cover 210 and the second cover 240 are in contact with each other, the engaging protrusion 253a (253b) of the first cover 210 and the engaging protrusion 253c (253d) of the second cover 240 that face each other are integrated to form a substantially reverse triangle shape in a front view. This substantially reverse triangle shape corresponds to the shape of the opening 123 that forms the internal space S1 of the tumble 120.
[0056] When attaching the covers 203 and 204 for a hanging pipe support shown in FIGS. 9 to 13 to the hanging pipe support 100, in the same manner as described with reference to FIGS. 3 to 8, first, the hanging pipe support 100 is guided into the internal space S2 of the first cover 210, and the shaft portion 113 of the hanging bolt 110 is fitted into the groove portion 251a of the first cover 210, and the nut 115 is arranged to be fitted into the first engaging recess 252a, thereby positioning the covers 203 and 204 for a hanging pipe support with respect to the hanging pipe support 100 (see FIGS. 11 to 13). Further, when guiding the hanging pipe support 100 into the internal space S2 of the first cover 210, the engaging protrusions 253a and 253b provided on the first cover 210 are guided over the edge of the reverse triangle portion 121 and into the inside of the opening 123, thereby guiding them into the internal space S1.
[0057] The engaging convex portions 253a and 253b can also be elastically deformed in the same manner as the engaging protrusions 250a and 250b. Therefore, by elastically deforming the engaging convex portions 253a and 253b, the edge of the inverted triangular portion 121 can be overcome, and after overcoming the edge, in the internal space S1 inside the opening 123, the shape of the engaging convex portions 253a and 253b can be restored to adapt to the internal shape of the internal space S1.
[0058] In this way, by attaching the first cover 210 to the suspension pipe support 100, as shown in FIGS. 11 to 13, it becomes possible to position and temporarily fix the first cover 210. After attaching the first cover 210 to the suspension pipe support 100, by moving the second cover 240 to the side of the suspension pipe support 100 via the connecting portion 220, similar to the first cover 210, the suspension pipe support 100 is guided into the internal space S2 of the second cover 240, the shaft portion 113 of the suspension bolt 110 is fitted into the groove portion 251b of the second cover while the nut 115 is fitted into the first engaging concave portion 252b, and further, the engaging convex portions 253c and 253d provided on the second cover 240 can overcome the edge of the inverted triangular portion 121 and be guided into the internal space S1.
[0059] First, by positioning and temporarily fixing the first cover 210, the covers 203 and 204 for the suspension pipe support will not easily come off or fall from the suspension pipe support 100. Therefore, the attachment of the first cover 210 to the suspension pipe support 100 becomes easier, and it is possible to securely attach the first cover 210 to the suspension pipe support 100.
[0060] Also, after positioning and temporarily fixing with the first cover 210 in this way, by attaching the second cover 240 to the suspended pipe support 100, it becomes possible to securely and accurately attach the covers 203 and 204 for the suspended pipe support to the suspended pipe support 100 without being affected by the skill level of the operator. Furthermore, by using the engaging convex portions 253a to 253d and the first engaging concave portions 252a and 252b, the positioning of the first cover 210 and the attachment of the second cover 240 can be easily performed, thus reducing the attachment burden on the operator. Also, by the operator closing the boundary between the first cover 210 and the second cover 240 with tape or the like, it is possible to prevent gaps or the like from remaining in the covers 203 and 204 for the suspended pipe support, and it becomes possible to ensure higher heat insulation and cold insulation properties.
[0061] FIG. 14 is a front view showing a cover for a suspended pipe support provided with engaging convex portions, and in the cover for a suspended pipe support without the lower portions of the first cover and the second cover, the cover 205 for a suspended pipe support obtained by vertically dividing the first cover and the second cover along the cross-sectional direction of the pipe 300. In the cover 205 for a suspended pipe support, the first cover 210 and the second cover 240 are connected by a connecting portion 220 at their respective side portions. In the cover 205 for a suspended pipe support, an engaging convex portion 235e having an inverted triangular shape corresponding to the inverted triangular shape of the inverted triangular portion 121 is provided at the central portion of the inner wall surface 221a of the first cover 210. Also, an engaging convex portion 235f having an inverted triangular shape corresponding to the inverted triangular shape of the inverted triangular portion 121 is provided at the central portion of the inner wall surface 221b of the second cover 240.
[0062] The inverted triangular shape of the engaging convex portion 235e is the shape and size obtained by combining the engaging convex portion 253a and the engaging convex portion 253c described with reference to FIGS. 9 to 13. Further, the inverted triangular shape of the engaging convex portion 235f is the shape and size obtained by combining the engaging convex portion 253b and the engaging convex portion 253d described with reference to FIGS. 9 to 13. Therefore, when attaching the cover 205 for the suspended pipe support to the suspended pipe support 100, the suspended pipe support 100 is introduced into the internal space S2 of the first cover 210, the shaft portion 113 of the suspension bolt 110 is fitted into the groove portion 251a of the first cover 210, the nut 115 is fitted into the first engaging concave portion 252a, and the engaging convex portion 235e is arranged so as to be fitted into the internal space S1 of the inverted triangular portion 121, thereby positioning the cover 205 for the suspended pipe support with respect to the suspended pipe support 100.
[0063] After attaching (positioning and temporarily fixing) the first cover 210 to the suspended pipe support 100, by pulling (moving) the second cover 240 toward the suspended pipe support 100 via the connecting portion 220, the suspended pipe support 100 is introduced into the internal space S2 of the second cover 240, the shaft portion 113 of the suspension bolt 110 is fitted into the groove portion 251b of the second cover 240, the nut 115 is fitted into the second engaging concave portion 252b, and the engaging convex portion 235f is arranged so as to be fitted into the internal space S1 of the inverted triangular portion 121, thereby attaching the cover 205 for the suspended pipe support to the suspended pipe support 100. In this way, even when attaching the cover 205 for the suspended pipe support to the suspended pipe support 100, the cover 205 for the suspended pipe support can be securely and accurately attached to the suspended pipe support 100 without being affected by the skill of the operator, and the attachment burden on the operator can be reduced.
[0064] Next, a case will be described in which, instead of the engaging protrusions 250a to 250d and the engaging convex portions 253a to 253f, second engaging recesses (referred to as second engaging recesses) are provided in the first cover 210 and the second cover 240. FIGS. 15 to 20 are views showing cover members 206 and 207 for a suspended pipe support, in which second engaging recesses that engage with bolts 141 and nuts 142 in a fastening member 140 of the suspended pipe support 100 are provided, instead of the engaging protrusions 250a to 250d and the engaging convex portions 253a to 253f shown in FIGS. 3 to 14.
[0065] On the inner wall surface 221a of the first cover 210, in addition to the groove portion 251a and the first engaging recess 252a already described, a recess (second engaging recess 254, head engaging recess) into which the head 141b of the bolt 141 can be fitted is formed. The internal shape of the second engaging recess 254 corresponds to the external shape of the head 141b of the bolt 141, and the head 141b can be fitted into the second engaging recess 254. The head 141b fitted into the second engaging recess 254 is elastically held by the elastic deformation of the first cover 210. For this reason, the first cover 210 is positioned and temporarily fixed with respect to the suspended pipe support 100.
[0066] Also, on the inner wall surface 221b of the second cover 240, in addition to the groove portion 251b and the first engaging recess 252b already described, a recess (second engaging recess 255, shaft engaging recess) into which the tip of the shaft portion 141a of the bolt 141 can be fitted is formed. The internal shape of the second engaging recess 255 corresponds to the external shape of the shaft portion 141a of the bolt 141, and the shaft portion 141a can be fitted into the second engaging recess 255. The shaft portion 141a fitted into the second engaging recess 255 is elastically held by the elastic deformation of the second cover 240.
[0067] When attaching the coverings 206, 207 for the hanging pipe support to the hanging pipe support 100 shown in FIGS. 15 to 20, similar to the case described with reference to FIGS. 3 to 8 and FIGS. 9 to 14, first, introduce the hanging pipe support 100 into the internal space S2 of the first cover 210, fit the shaft portion 113 of the hanging bolt 110 into the groove portion 251a of the first cover 210, fit the nut 115 into the first engaging recess 252a, and arrange the head portion 141b of the bolt 141 to fit into the second engaging recess 254, thereby positioning the coverings 206, 207 for the hanging pipe support with respect to the hanging pipe support 100 (see FIGS. 17 to 20).
[0068] In this way, by attaching the first cover 210 to the hanging pipe support 100, as shown in FIGS. 17 to 20, it becomes possible to position and temporarily fix the first cover 210. After attaching the first cover 210 to the hanging pipe support 100, by pulling (moving) the second cover 240 toward the hanging pipe support 100 side via the connecting portion 220, similar to the first cover 210, introduce the hanging pipe support 100 into the internal space S2 of the second cover 240, fit the shaft portion 113 of the hanging bolt 110 into the groove portion 251b of the second cover 240, fit the nut 115 into the first engaging recess 252b, and fit the shaft portion 141a of the bolt 141 into the second engaging recess 255, thereby attaching the second cover 240 to the hanging pipe support 100.
[0069] First, by positioning and temporarily fixing the first cover 210 with respect to the hanging pipe support 100, the coverings 206, 207 for the hanging pipe support are prevented from easily coming off or falling from the hanging pipe support 100. For this reason, the attachment of the first cover 210 to the hanging pipe support 100 becomes easier, and it becomes possible to securely attach the first cover 210 to the hanging pipe support 100.
[0070] Also, after positioning and temporarily fixing with the first cover 210 in this way, by attaching the second cover 240 to the suspension pipe support 100, it becomes possible to securely and accurately attach the covers 206 and 207 for the suspension pipe support to the suspension pipe support 100 without being affected by the skill level of the operator. Furthermore, by using the first engaging recesses 252a and 252b and the second engaging recesses 254 and 255, the positioning of the first cover 210 and the attachment of the second cover 240 can be easily performed, so that the attachment burden on the operator can be reduced. Also, by the operator closing the boundary between the first cover 210 and the second cover 240 with tape or the like, it is possible to prevent gaps or the like from remaining in the cover 200 for the suspension pipe support, and it becomes possible to ensure higher heat insulation and cold insulation properties.
[0071] Figs. 21 to 23 are views showing a cover for a suspension pipe support that is divided at a position different from the covers 206 and 207 for the suspension pipe support shown in Figs. 15 to 20. The covers 208 and 209 for the suspension pipe support shown in Figs. 21 to 23 are composed of a first cover 210a and a second cover 240a that are vertically divided along the axis of the shaft portion 141a of the bolt 141 (or along the cross-sectional direction of the pipe 300) and are symmetric about the vertical axis. For this reason, the second engaging recess 254 into which the head 141b of the bolt 141 can be fitted is in a state of being divided into a second engaging recess 254a provided on the inner wall surface 221a of the first cover 210a and a second engaging recess 254b provided on the inner wall surface 221b of the second cover 240a. Similarly, the second engaging recess 255 into which the shaft portion 141a of the bolt 141 can be fitted is in a state of being divided into a second engaging recess 255a provided on the inner wall surface 221a of the first cover 210a and a second engaging recess 255b provided on the inner wall surface 221b of the second cover 240a.
[0072] Thus, even when the second engagement recesses 254 and 255 are divided into left and right parts, the right half (left half) of the shaft portion 141a and the head portion 141b of the bolt 141 are fitted into the second engagement recesses 254a (254b) and 255a (255b), so that the shaft portion 141a and the head portion 141b are elastically held by the first cover 210a (the second cover 240a). Therefore, it becomes possible to position and temporarily fix the first cover 210a (the second cover 240a) with respect to the suspension pipe support 100.
[0073] In the cover 208 for the suspension pipe support shown in FIGS. 21 and 22, a connecting portion 220 is provided at the upper end portions of the first cover 210a and the second cover 240a and they are connected. When attaching the cover 208 for the suspension pipe support to the suspension pipe support 100, as already described with reference to FIGS. 3 to 20, after attaching (positioning and temporarily fixing) the first cover 210a to the suspension pipe support 100, the second cover 240a can be pulled (moved) and attached to the suspension pipe support 100 via the connecting portion 220 (see FIGS. 21 and 22). Also in this case, the cover 208 for the suspension pipe support can be surely and accurately attached to the suspension pipe support 100 without being influenced by the skill of the operator, and the attachment burden on the operator can be reduced.
[0074] In the cover 209 for the suspension pipe support shown in FIG. 23, a connecting portion 220 is provided at the side portions of the first cover 210a and the second cover 240a and they are connected. Thus, even when the connecting portion 220 is provided at the side portions of the first cover 210a and the second cover 240a, as already described, after attaching (positioning and temporarily fixing) the first cover 210a to the suspension pipe support 100, the second cover 240a can be pulled (moved) and attached to the suspension pipe support 100 via the connecting portion 220. Also in this case, the cover 208 for the suspension pipe support can be surely and accurately attached to the suspension pipe support 100 without being influenced by the skill of the operator, and the attachment burden on the operator can be reduced.
[0075] As described above, the cover for the hanging pipe support according to the present invention has been described in detail with reference to the drawings. However, the cover for the hanging pipe support according to the present invention is not limited to the examples shown in the embodiments. For example, in the embodiments, after attaching (positioning and temporarily fixing) the first covers 210 and 210a to the hanging pipe support 100, the covers 200 to 209 for the hanging pipe support are attached to the hanging pipe support 100 based on the procedure of attaching the second covers 240 and 240a to the hanging pipe support 100. However, when attaching the covers 200 to 209 for the hanging pipe support to the hanging pipe support 100, it is also possible to first attach (position and temporarily fix) the covers 204 and 204a for the hanging pipe support to the hanging pipe support 100, and then attach the first covers 210 and 210a to the hanging pipe support 100.
[0076] Also, in the covers 200 to 209 for the hanging pipe support shown in the embodiments, the first engaging recesses 252a and 252b were always provided. However, when the engaging protrusions 250a to 250d, the engaging convex portions 253a to 253f, and the second engaging recesses 254, 254a, 254b, 255, 255a, and 255b are provided, it is also possible to omit the first engaging recesses 252a and 252b. Further, without providing the engaging protrusions 250a to 250d, the engaging convex portions 253a to 253f, and the second engaging recesses 254, 254a, 254b, 255, 255a, and 255b on the first covers 210 and 210a and the second covers 240 and 240a, only the groove portions 251a and 251a and the first engaging recesses 252a and 252b may be provided on the first covers 210 and 210a and the second covers 240 and 240a.
[0077] If the grooves 251a, 251b and the first engagement recesses 252a, 252b are provided in the first cover 210, 210a and the second cover 240, 240a, the grooves 251a, 251b and the first engagement recesses 252a, 252b can position and temporarily fasten the first cover 210, 210a (second cover 240, 240a) to the hanging pipe support 100. Therefore, even with such a configuration, it is possible to achieve the same effects as in the example shown in the embodiment.
[0078] Furthermore, in the hanging pipe support covers 200-209 shown in the embodiments, the first cover 210, 210a and the second cover 240, 240a are described as being provided with either the engaging protrusions 250a-250d or the second engaging recesses 254, 254a, 254b, 255, 255a, 255b. Also, the embodiments are described as being provided with either the engaging protrusions 253a-253f or the second engaging recesses 254, 254a, 254b, 255, 255a, 255b. However, the second engaging recesses 254, 254a, 254b, 255, 255a, 255b can also be provided simultaneously with the engaging protrusions 250a-250d or the engaging protrusions 253a-253f. Therefore, in addition to the second engaging recesses 254, 254a, 254b, 255, 255a, and 255b, it is also possible to provide engaging protrusions 250a to 250d or engaging convex portions 253a to 253f.
[0079] Furthermore, in the hanging pipe support covers 200 to 205 in the embodiments, the engaging protrusions 250a to 250d and the engaging protrusions 253a to 253f are provided on both the first cover 210 and the second cover 240. However, the configuration is not limited to the engaging protrusions 250a to 250d and the engaging protrusions 253a to 253f being provided on both the first cover 210 and the second cover 240. The hanging pipe support cover according to the present invention can also be configured such that the engaging protrusions 250a to 250d and the engaging protrusions 253a to 253f are provided on only at least one of the first cover 210 and the second cover 240.
[0080] Furthermore, in the covers 206 to 209 for the hanging pipe support tool in the embodiment, the case where the second engaging recess 254 into which the head 141b of the bolt 141 can be fitted is provided in the first cover 210a, and further, the second engaging recess 255 into which the shaft portion 141a of the bolt 141 can be fitted is provided in the second cover 240a was described. However, the cover for the hanging pipe support tool according to the present invention is not limited to the configuration in which both the second engaging recess 254 and the second engaging recess 255 are provided for the covers 206 to 209 for the hanging pipe support tool. In the cover for the hanging pipe support tool according to the present invention, it is also possible to adopt a configuration in which only at least one of the second engaging recess 254 and the second engaging recess 255 is provided for the covers 206 to 209 for the hanging pipe support tool.
[0081] Also, in the covers 200 to 209 for the hanging pipe support tool in the embodiment, the case where the connecting portion 220 is provided at the upper ends, lower ends, and side portions of the first covers 210, 210a and the second covers 240, 240a was described. However, the position where the connecting portion 220 is provided is not limited to only the upper ends, lower ends, and side portions of the first covers 210, 210a and the second covers 240, 240a. As long as the hanging pipe support tool 100 can be enclosed by the divided covers for the hanging pipe support tool and the outside of the hanging pipe support tool 100 can be covered, the arrangement position of the connecting portion 220 is not particularly limited.
[0082] Furthermore, in the covers 200 to 209 for the hanging pipe support in the embodiment, the case where the first covers 210, 210a and the second covers 240, 240a are divided so as to be symmetric or substantially equal to each other in the left-right direction has been described. However, the shapes and sizes of the divided first covers 210, 210a and second covers 240, 240a do not necessarily have to be symmetric in the left-right direction. The position where they are divided is not limited to a configuration where they are vertically divided at the center of the covers 200 to 209 for the hanging pipe support, and they may be vertically divided at a position offset from the center. No matter how the covers 200 to 209 for the hanging pipe support are divided, after guiding the hanging pipe support 100 into one cover (the first cover or the second cover) and positioning and temporarily fixing it, by attaching the other cover (the second cover or the first cover) to the hanging pipe support 100, as long as it is a configuration capable of realizing the heat insulation and cold insulation effects on the hanging pipe support 100, the division position, division shape, etc. are not particularly limited.
