Description

  The present invention is a holder for a heat insulating material or the like mainly used in a heat insulating method for a steel building, and particularly suitable for attaching a heat insulating material to the lower surface of a beam material made of H-shaped steel or I-shaped steel. The present invention relates to a holder such as a material.

  The heat insulation method for steel buildings is an external heat insulation method (outside heat insulation method) in which a heat insulating material is pasted on the outside of the frame composed of columns, beams, etc. An inner heat insulating method (lining heat insulating method, filling heat insulating method) is known in which a heat insulating material is pasted or filled on the inside of the housing to form a heat insulating line. Each heat insulation method has advantages and disadvantages, and is selectively used according to various circumstances or appropriately combined.

  Among the heat insulation methods, the inner heat insulation method is disclosed in, for example, Patent Documents 1 and 2. Insulating materials often used in the inner heat insulation method include fiber-based heat insulating materials such as glass wool filled into a bag made of waterproof and moisture-permeable sheets, etc., and formed into a mat shape, rigid urethane foam, polystyrene foam, phenol A resin foam or the like formed in a board shape is representative.

  By the way, in a building with two or more floors, a part of the upper floor overhangs outside the lower floor due to a piloti or entrance alcove on the lower floor, etc., and the floor under the overhang is exposed to the outside air. There may be a facing eave heaven. In such an eaves ceiling part, it is necessary to provide a heat insulation line in the horizontal direction so as to connect the heat insulation line provided along the outer wall of the lower floor and the heat insulation line provided along the outer wall of the upper floor. is there. Patent Document 3 discloses a heat insulating structure for a steel-framed house having such an eave heaven, and an outline thereof is shown in FIGS. 14 to 16.

  In the illustrated building (house), a part of the outer wall 11 of the upper floor 10 overhangs on the outdoor side (left side in the figure) from the outer wall of the lower floor 12, and a part of the floor below the upper floor 10 is the sky. It becomes part 13. On the upper floor 10, the wall heat insulating material 21 built on the indoor side of the outer wall 11, the outer peripheral end of the ALC panel 32 constituting the floor 31 of the overhang portion, and the side surface of the outer floor beam 33 are stretched. The heat insulation line 14 on the upper floor is formed by the in-beam heat insulating material 22. Further, on the lower floor 12, a heat insulating line 16 on the lower floor is formed by a wall heat insulating material 23 built on the indoor side of the outer wall 15.

  As for the overhang portion, the ALC panel 32 constituting the floor 31 is supported by a plurality of floor beams 33, 34, 35, 36, etc. made of H-section steel, and within the frame of the horizontal plane surrounded by them. Further, an inter-beam heat insulating material 24 as a first heat insulating material is filled. The inter-beam heat insulating material 24 is, for example, a fiber heat insulating material formed into a panel shape and covered with a resin film, and is placed on the lower flanges of the adjacent floor beams 33, 34, 35, 36, and , 34, 35, and 36 are closed. Although not shown in the figure, when a connecting material or a horizontal brace is arranged between the adjacent floor beams 33, 34, 35, 36, the inter-beam heat insulating material 24 is placed on them. The inter-beam insulation 24 can be supported so as not to bend.

  In addition, the specific floor beam 34 located near the middle of the overhang portion is covered with the under-beam heat insulating material 25 as the second heat insulating material in order to prevent the floor beam 34 from becoming a thermal bridge. The under-beam heat insulating material 25 is made of, for example, a fibrous heat insulating material coated with a resin film so as to be highly deformable, and the lower half of the floor beam 34 is formed using the pressing material 40 shown in FIGS. 15 and 16. It is attached to wrap.

  The pressing member 40 is an elastically deformable member formed by bending a bar made of metal or synthetic resin. The pressing member 40 includes a bottom portion 41 pressed against the lower surface portion of the under-beam heat insulating material 25, and a pair of side portions 42 and 42 that rise from both ends of the bottom portion 41 and press the side surface portions of the under-beam heat insulating material 25. Yes. The side portions 42 and 42 are close to each other toward the tip, and the tips can be elastically expanded. The width of the bottom portion 41 is slightly larger than the width of the lower flange 341 of the floor beam 34, and the distance between the tips of the side portions 42 and 42 is smaller than the width of the lower flange 341. The front ends of the side portions 42 and 42 are folded back in directions away from each other so as not to break the resin film of the under-beam heat insulating material 25. Such a pressing member 40 is fitted from below into the under-beam heat insulating material 25 applied to the lower flange 341 of the floor beam 34 while elastically deforming the ends of the side portions 42 and 42 so as to expand each other. Then, by returning elastically, the under-beam heat insulating material 25 can be fixed to the lower flange 341 of the floor beam 34.

  And the horizontal eaves back heat insulation line 17 is formed in the eaves top part 13 which contact | connects outside air with such an inter-beam heat insulating material 24 and the under-beam heat insulating material 25. FIG.

JP 2004-76314 A JP 2010-37740 A JP 2009-293344 A

  The construction procedure of the heat insulation structure of the eaves top part described in Patent Document 3 is to cover the lower half of the floor beam 34 made of H-shaped steel with the under-beam heat insulating material 25 and then to the lower flange 341 of the floor beam 34 between the beams. It is understood that the heat insulating material 24 is placed and bridged between the floor beams 33, 35, 36, etc. (paragraphs 0019 to 0021). However, in the construction procedure, the under-beam heat insulating material 25 attached so as to wrap the lower half of the floor beam 34 is in the way, and the inter-beam heat insulating material 24 is placed on the lower flange 341 of the floor beam 34 in every corner. It becomes difficult to mount.

  In addition, the work of attaching the under-beam heat insulating material 25 to the floor beam 34 is performed by holding the under-beam heat insulating material 25 and the pressing member 40 and pressing the under-beam heat insulating material 25 against the floor beam 34 with one hand. It is assumed that the holding material is fitted to the lower flange 341 of the floor beam 34 with the other hand. However, in an unstable posture climbing on a stepladder or the like, while pushing up the under-beam heat insulating material 25 having a considerable length with one hand, the holding material 40 is elastically deformed with the other hand and attached to the lower flange. The physical burden is large and the workability is reduced.

  The present invention has been made mainly for the purpose of improving the workability of the heat insulation structure of the eaves, such as a mat-like or board-like heat insulating material on the lower surface of a floor beam or the like made of H-shaped steel. It is an object of the present invention to provide a holder that fits easily and can be easily and quickly attached.

  The holder of the present invention is based on the premise that the heat insulating material having a width wider than that of the plate-like member is attached to one surface of the plate-like member having a substantially constant width. Here, the “plate member” includes not only a flange portion of H-shaped steel or I steel material, but also a plate member for construction made of various similar materials (metal or other relatively hard materials). In addition to “general heat insulation materials molded into mats or boards”, “heat insulation materials” are relatively soft, such as fireproof covering materials, sound absorbing materials (soundproof materials), moisture absorption adjusting agents, etc. It also includes molding materials and composite materials made of lightweight materials.

  The holder includes a clip portion that can be hooked on an edge portion of the plate-like member, and an arm portion that extends from the clip portion and can grip an edge portion of the heat insulating material or the like. When the clip portions of the holding member halves are respectively hooked on both edge portions of the plate-like member, the arms of the two holding member halves are formed so as to face each other along the surface of one side of the plate-like member. It is characterized by that.

  The “hanging” here includes not only the mode of hooking to the extent that it does not fall, but also the mode of sandwiching the plate-like member with an appropriate strength in the thickness direction. Further, “gripping” is used to mean that the heat insulating material or the like is held slightly softly while being pressed not only in the thickness direction but also in the width direction. However, it is not intended to be used strictly between “hanging” and “gripping”.

  A holder such as a heat insulating material configured in this way can be very easily attached to an arbitrary position of the plate-like member using a clip portion provided in each holder half. This attachment does not require screws or other attachment members, drilling holes, etc., and no tools are required. Furthermore, it is possible to attach only the half of the retainer to the floor beam, etc., which is laid over a high place, so the work load is higher than that of the construction method in which the heat insulating material and the retainer are fixed together while being lifted together. Can be greatly reduced.

  In addition, a pair of holder halves attached to both edges of the plate-like member are opposed to each other along the surface of one side of the plate-like member, and by inserting a mat-like heat-insulating material between them, the heat-insulating material etc. is extremely simple. Can be attached to. Also for this work, there is no need for screws, other members, drilling of the prepared holes, or the like. A heat insulating material etc. are hold | maintained so that it may be held from both sides by the elastic deformation of an arm part. The arm portion does not damage the surface (packaging) of the heat insulating material, make a hole in the heat insulating material, or forcefully deform the heat insulating material. Further, even if the width of the plate-like member is somewhat large, a heat insulating material or the like can be similarly attached using the same holding member half.

  Further, according to the present invention, in the configuration described above, at least one of the holder halves is provided with an engaging portion, and the other holder half is provided with an engaged portion corresponding to the engaging portion. And the engaging portion and the engaged portion are placed on one side surface of the plate-like member in a state where the clip portions of the two holder halves are respectively hooked on both edge portions of the plate-like member. When they are overlapped with each other and engaged with each other, the opposing distance between the two holding tool halves is held at a predetermined size.

  According to this configuration, the pair of holder halves are integrally coupled with the plate-like member sandwiched therebetween, and are firmly fixed to the plate-like member. It becomes easy to prevent the insulating material or the like from dropping off from the plate-like member or the distance between the two holding tool halves being expanded.

  Furthermore, in the above-described configuration, the present invention is formed such that the engaging portion and the engaged portion of the holding member half can be engaged at a plurality of engaging positions, and according to the engaging positions. In this case, the facing distance between the two holder halves is changed stepwise. According to this configuration, the same holder half can be similarly attached to a plurality of types of plate-like members having different widths.

  Further, according to the present invention, in the above-described configuration, each holding tool half is provided with one engaging portion and one engaged portion, and the engaging portion and the engaged portion are respectively provided. It is characterized by engaging with the engaged portion and the engaging portion of the other holder half.

  According to this configuration, since the engaging-side holding half and the engaged-side holding half can be combined in the same shape without being distinguished, Only one type is enough. Thereby, component procurement costs can be reduced.

  Further, according to the present invention, as a specific configuration of the above-described holding member half, the clip portion includes an attachment base piece extending along one surface of the plate-like member, and a thickness of the plate-like member from the attachment base piece. Each of the holding member halves extends from the clip part to the width of the plate-like member. A widened portion projecting in the direction, a side hug extending from the widened portion in the thickness direction of a heat insulating material, and a presser extending from the tip of the side hug so as to face the contact base piece And a piece.

  Furthermore, in this configuration, it is rational that at least one of the engaging portion or the engaged portion is formed in the vicinity of the distal end of the attachment base piece.

  Furthermore, in this configuration, it is preferable that the engaging portion includes a claw-shaped protrusion, and the engaged portion includes a hole or a concave portion into which the claw-shaped protrusion can be engaged.

  Furthermore, in this configuration, if the arm portion is formed so that the internal angle formed by the side holding portion and the pressing piece is smaller than 90 degrees, the holding force of the heat insulating material or the like increases, preferable.

  Furthermore, it is convenient that at least a part of the arm portion is formed so as to be foldable, since it does not become bulky when the holder half is housed or transported.

  Further, the pair of holding tool halves may be connected to each other in an inseparable or separable manner through an appropriate connecting member formed separately from the holding tool halves.

  The holder such as the heat insulating material of the present invention configured as described above can be placed at an arbitrary position of the plate-like member simply by hooking the clip portion provided on the half of the holder to the edge of the plate-like member. Easy to install. And a heat insulating material etc. can also be easily attached only to the both edge parts of a plate-shaped member by attaching the arm part of a pair of holding tool half so as to oppose each other, and pushing a heat insulating material etc. between them. Thus, if the holder such as the heat insulating material of the present invention is used, it is possible to adopt a construction procedure in which the holder is fixed to the beam material in advance and then the heat insulating material is attached to the holder. Therefore, the work burden is greatly reduced as compared with the conventional construction method in which the holder and the heat insulating material are lifted together and attached to a high place.

  In addition, the holder such as a heat insulating material according to the present invention is configured so that a heat insulating material or the like formed in a mat shape or a panel shape is provided in a substantially flat state along the one side surface of the plate-like member. There is no need to forcibly deform the heat insulating material or the like. Since the heat insulating material and the like are held so as to be held from both sides by elastic deformation of the arm portion, the mounting state is stable and the possibility of dropping off is small.

  And when applied to the heat insulation structure of the eaves-top part shown in FIG. 14, the heat insulating material 2 hold | maintained on the lower surface of the floor beam 34 with holders, such as a heat insulating material of this invention (refer FIG. 2, 3 etc.). However, since it does not interfere with the inter-beam heat insulating material 24 filled in the frame of the construction surface surrounded by the floor beams 33, 34, 35, 36, etc., the inter-beam heat insulating material 24 is better accommodated and the workability is improved.

  Further, when a configuration is adopted in which the pair of holding tool halves are integrally coupled by the engagement of the engaging part and the engaged part, the holding tool is further layered on the plate-like member. It is firmly fixed.

  By these, especially when implementing the heat insulation structure of the eaves part as described in the background art, the workability can be greatly improved.

(First embodiment)
1 to 3 show a holder 5A according to a first embodiment of the present invention. As shown in FIG. 1, the holder 5A is formed by pairing two holder halves 51 and 52 having slightly different shapes. Then, as shown in FIGS. 2 and 3, for example, a mat-like or panel-like heat insulation having a width slightly larger than the width of the lower flange 30 on the lower surface of the lower flange 30 such as an H-section steel 3 that becomes a floor beam. It is attached to attach material 2 etc.

  Both of the two holder halves 51 and 52 are integrally formed of a synthetic resin material (for example, polyvinyl chloride or the like) that has a low thermal conductivity and can be elastically deformed appropriately. Further, both of the holder halves 51 and 52 are clip portions 6 that can be hooked to the edge portion of the lower flange 30, and arm portions 7 that extend from the clip portion 6 and can grip the edge portion of the heat insulating material 2. And.

  The clip portion 6 includes a contact base piece 61 that extends linearly along the lower surface of the lower flange 30 and a latch piece 62 raised from the contact base piece 61 in the thickness direction of the lower flange 30. It is comprised so that it may open to the direction. The latching piece 62 is extended so as to face the attachment base piece 61 while being curved in a substantially S-shape when viewed from the front, and the tip thereof is reversed in a direction away from the attachment base piece 61. In the state where the external force does not act, the retaining piece 62 is slightly smaller than the thickness of the lower flange 30 (generally, 6 to 9 mm, and about 12 mm for a large cross-section beam). It is shaped so that it can be fitted to the lower flange 30 with appropriate elasticity.

  The arm portion 7 includes a widened portion 71 projecting from the attachment base piece 61 in the width direction of the lower flange 30, a side retaining portion 72 extending from the widened portion 71 in the thickness direction of the heat insulating material 2, and a side retaining portion 72. And a pressing piece 73 extending so as to be opposed to the contact base piece 61 from the tip thereof, and these are continuous in a substantially U shape in front view and open in the same direction as the clip portion 6. . The length of the side holding portion 72 corresponds to the thickness of the heat insulating material 2 to be gripped. About the thickness of the heat insulating material 2, for example, based on the “Next Generation Energy Saving Standards” announced by the Ministry of Land, Infrastructure, Transport and Tourism and Ministry of Economy, Trade and Industry, etc., depending on the building area, building structure, heat insulating part, type of heat insulating material, etc. Although it is appropriately selected within a range of around 200 mm, in the exemplary embodiment, it is set to about 100 mm. Further, the internal angle formed by the widened portion 71 and the side holding portion 72 is about 90 degrees when no external force is applied, and the internal angle formed by the side holding portion 72 and the holding piece 73 is more than 90 degrees when no external force is applied. The heat insulating material 2 can be elastically gripped by being shaped so as to be slightly smaller from 75 to 85 degrees.

  Depth D (dimensions along the axial direction of the H-section steel 3) of the attachment base piece 61 and the latching piece 62 constituting the clip portion 6, and the widening portion 71, the side holding portion 72 and the holding piece 73 constituting the arm portion 7. ) Is uniform throughout.

  The pair of holder halves 51 and 52 according to the first embodiment is different from each other in that the engaging part 8 is provided in one (left side in the figure) and the other (right side in the figure). This is in that the engaged portion 9 is provided in the holder half 52 of the other.

  The engaging portion 8 provided on one holding tool half 51 is formed by providing one claw-like protrusion 81 on the lower surface (arm portion 7 side) near the tip of the attachment base piece 61. The claw-like protrusion 81 is rectangular in a bottom view, has a substantially triangular cross-sectional shape that is uniform in the depth direction of the attachment base piece 61, and has a shallow angle (approximately 20 to approximately 20 to the tip side of the attachment base piece 61. 30 degrees) and a locking surface 83 that is substantially orthogonal to the contact base piece 61 (see a circled portion in FIG. 2). The length along the depth direction of the claw-like projection 81 is approximately 1/2 to 2/3 of the length along the depth D direction of the entire attachment base piece 61.

  The engaged portion 9 provided on the other holding member half 52 drops the substantially half portion on the distal end side of the attachment base piece 61 to the pressing piece 73 side by the thickness of the attachment base piece 61, A plurality of hole portions 91 (two in the illustrated embodiment) are provided in the stepped portion. Each hole 91 has a rectangular bottom shape into which the above-described claw-shaped protrusion 81 is fitted, and an appropriate interval is provided between each hole 91. It should be noted that the engaged portion 9 can be configured by a bottomed concave portion or other forms (not shown) instead of the hole portion 91 penetrating the attachment base piece 61.

  Then, as shown in FIGS. 2 and 3, the pair of holder halves 51 and 52 hangs the clip portions 6 on both edge portions of the lower flange 30, and attaches the arm portions 7 and 7 to each other. It is attached in a state of facing each other. At this time, the engaging portion 8 of the holder half 51 and the engaged portion 9 of the holder half 52 are overlapped with the lower surface of the lower flange 30, and the claw-like protrusion 81 formed on the engaging portion 8. Engages with the hole 91 formed in the engaged portion 9. Here, in order to facilitate the overlapping of the engaging portion 8 and the engaged portion 9, the tip edge of the stepped portion constituting the engaged portion 9 has a shallow angle (generally toward the pressing piece 73 side). A welcome lip 92 that is bent at 10 to 20 degrees is formed. Due to such an engagement function, both the holding tool halves 51 and 52 are integrally coupled while the facing distance between the arm portions 7 and 7 is maintained at a predetermined size.

  FIG. 2 shows a state in which the claw-like projection 81 formed on the engaging portion 8 is engaged with the hole portion 91 on the distal end side among the two hole portions 91 provided on the engaged portion 9. ing. Further, FIG. 3 shows that the claw-like protrusion 81 formed on the engaging portion 8 is engaged with the hole 91 on the side holding portion 72 side among the two hole portions 91 provided on the engaged portion 9. Thus, the state in which the facing interval between the holding tool halves 51 and 52 is smaller than that in FIG. 2 is shown. Thus, if the hole 91 for engaging the claw-shaped protrusion 81 is selected in accordance with the width of the lower flange 30, it is possible to change the facing distance between the holder halves 51, 52 stepwise. As a result, the same holder 5A can be well fitted to the lower flange 30 having a different width.

  After attaching the holding tool halves 51 and 52 to both edges of the lower flange 30 and then inserting the mat-like heat insulating material 2 between them, the heat insulating material 2 is held from both sides by elastic deformation of the arm portion 7. To be held. In the case of the board-shaped heat insulating material 2, it may be inserted between the arm portions 7 and 7 while sliding along the depth D direction of the holder 5A. In this way, the lower surface of the floor beam made of H-shaped steel 3 or the like can be covered in a heat-insulating manner.

(Second Embodiment)
FIG. 4 shows a holder 5B according to the second embodiment. This holder 5B is obtained by modifying the holder 5A according to the first embodiment so that it can be attached to a special part of a building. Two holder halves 53 and 54 having different shapes are provided. It is configured in pairs.

  Each of the holding tool halves 53 and 54 includes a clip portion 6. Since the structure of the clip part 6 is the same as that of 1st Embodiment, the same code | symbol is attached | subjected to a common site | part and member, and detailed description is abbreviate | omitted. Furthermore, the engagement base piece 61 having one claw-like projection 81 is provided on the attachment base piece 61 of one (left side in the figure) of the holder half 53, and the other (right side in the figure). An engagement base 9 having two holes 91 is provided on the attachment base piece 61 of the holder half 54. The configurations of the engaging portion 8 and the engaged portion 9 and the form of mutual engagement are the same as in the first embodiment.

  The difference from the first embodiment is that one holding member half 53 is provided with the wide arm portion 7 and the other holding member half 54 is not provided with the arm portion 7.

  The arm portion 7 provided on one holding member half 53 is similar to the arm portion 7 of the holding member halves 51 and 52 according to the first embodiment described above in the width direction of the lower flange 30 from the attachment base piece 61.

The pressing pieces 74 are continuous in a substantially U shape in front view and open in the same direction as the clip portion 6. However, the protruding width of the pressing piece 74 is considerably larger than that of the pressing piece 73 of the first embodiment, and is set to a dimension that exceeds at least half the width of the heat insulating material 2 (not shown) to be held. Further, a part near the distal end of the pressing piece 74 is shaped to fold upward at a shallower angle than the proximal end side. About the shape of the wide part 71 and the side holding part 72, it is the same as that of the holder half bodies 51 and 52 which concern on 1st Embodiment.

  The other holding member half 54 does not include portions corresponding to the widened portion 71, the side holding portion 72, and the pressing piece 73 of the holding member halves 51 and 52 according to the first embodiment. The holder half 54 can hold the arm portion 7 on one side of the lower flange 30 due to circumstances such that one side of a floor beam made of, for example, H-shaped steel 3 is in contact with the outer wall (the outer peripheral portion of the building). When there is not only an effective space, it is attached to that part, and the engaged portion 9 is engaged with the engaging portion 8 of the counterpart holder half 53. The heat insulating material 2 is held in a cantilever manner only by the arm portion 7 of the counterpart holder half 53.

5 to 7 show a holder 5C according to the third embodiment. The holder 5C is composed of two holder halves 55 and 55 having the same shape. Each holding tool half 55 includes the clip part 6 and the arm part 7 similar to the holding tool 5A according to the first embodiment described above. About these, the same code | symbol is attached | subjected to the site | part and member which are common in 1st Embodiment, and detailed description is abbreviate | omitted.

  In the third embodiment, both the engaging portion 8 and the engaged portion 9 are provided in one holder half 55, and the engaging portion 8 and the engaged portion 9 are respectively connected to the other party. Engage with the engaged portion 9 and the engaging portion 8 provided on the holder half 55. Specifically, as shown in FIG. 5, the attachment base piece 61 of each holding tool half 55 is divided into two in the depth D direction, one side being the engaging portion 8, and the other side being the engaged portion. Nine. The engaging portion 8 is formed by providing one claw-like protrusion 81 on the lower surface of the attachment base piece 61. The shape of the claw-shaped protrusion 81 is the same as that of the first embodiment except that the depth is small. The engaged portion 9 is formed by dropping the contact base piece 61 and extending to the tip side, and providing a plurality of (in the illustrated embodiment, two) hole portions 91 at the stepped portion. Yes. The shape of the hole 91 is the same as that of the first embodiment except that the depth is small.

  Then, as shown in FIGS. 6 and 7, the pair of holder halves 55, 55 hangs the respective clip portions 6 on the both edges of the lower flange 30, and attaches the arm portions 7, 7 to each other.
