Description

  The present invention relates to a hook-shaped fixing tool for a heat shield sheet, which fixes the heat shield sheet in a groove of a grooved frame.

  Conventionally, in order to arrange a heat shield sheet on a roof, a grooved frame is installed on the roof via a roof fixture, and the heat shield sheet is fixed and stretched by the grooved frame. A heat sheet mounting structure has been proposed (see Patent Document 1).

  In order to fix the heat shield sheet in a fixed state in the groove of the grooved frame in this way, first, the heat shield sheet is sandwiched between the groove inner surface of the grooved frame and the outer surface of the grooved interior frame. The inner frame and the heat shielding sheet are pressed into the groove, and on the inner bottom surface of the inner frame, both short sides of the fixing member made of a substantially rectangular flat plate are directed to both side walls in the groove, and the fixing member Then, a method is adopted in which both side walls of the groove are pressed to fix (temporarily fix) the heat shield sheet in the groove. In order to securely fix the heat shield sheet, a corrugated spring for fixing in the groove is further provided in the groove, and the frame cover is attached so as to close the groove opening and fixed with screws or the like.

  The fixing member is fitted into the both side walls of the groove by turning it about 90 degrees after dropping its long side into the groove in the longitudinal direction of the grooved frame. It can be fixed. For example, by inserting the tip of an L-shaped saddle-shaped driver into an operation groove provided on the surface of the fixing member and performing a rotation operation, the press-fitting attachment of the fixing member can be easily performed.

  By the way, the most troublesome work in attaching the heat shield sheet is to stretch the heat shield sheet between the groove-shaped frames with a certain degree of tension, and for that purpose, while maintaining the state where the heat shield sheet is stretched, The interior frame must be pressed into the groove of the grooved frame together with the heat shield sheet.

  However, conventionally, since the pressing operation has been performed using fingers or a tool nearby, the heat shield sheet may be loosened during the operation. That is, after attaching one end or the middle of the heat shield sheet to the grooved frame, when attaching another part of the heat shield sheet to another adjacent groove frame, the tension is reliably maintained with a strong force. In that case, it was forced to do difficult work.

  If the tension cannot be maintained when the heat shield sheet is pressed into the grooved frame, the fixing work cannot be performed with the fixing member in that state, so the pressing work is repeated until the tension is sufficiently high. I had to.

  The present invention has been proposed in view of such circumstances, and its purpose is simple and easy to carry, allowing both the pressing of the heat shield sheet into the groove of the grooved frame and the fixing by the fixing member. Another object is to provide a hook-shaped fixing tool for a heat shield sheet.

  In order to achieve the above object, the heat shield sheet saddle fixing tool according to claim 1 is a heat shield sheet saddle fixing tool for fixing the heat shield sheet in the groove of the grooved frame, The heat shield sheet is arranged in a state sandwiched between the groove inner surface of the grooved frame and the outer surface of the grooved interior frame, and is formed on the upper surface of the interior frame accommodated in the groove by a substantially rectangular flat plate. The fixing member has a fixing structure in which both the short sides of the fixing member are directed to both side walls in the groove and the heat shielding sheet is fixed in the groove by pressing both side walls. The part includes a pressing piece for pressing the interior frame into the groove of the grooved frame, and a rotating operation piece for rotating the fixing member at the other end.

  According to the hook-shaped fixing tool for the heat shield sheet according to claim 1, the rotation of rotating the fixing member at the other end is provided with a pressing piece for pressing the interior frame into the groove of the grooved frame at one end of the casing. Since the operation piece is provided, both the pressing operation of the heat shield sheet into the groove of the grooved frame and the fixing of the heat shield sheet by the fixing member can be performed with a single tool. In addition, since it is a bowl-shaped simple tool, it is convenient to carry and can be used comfortably on the roof.

FIG. 2 is a front view and a partially enlarged cross-sectional view showing an attachment state of the heat shield sheet attached using the hook-shaped fixing tool. FIG. 3 is a plan view and a partially enlarged plan view showing a mounting state of the heat shield sheet. Hereinafter, the hook-shaped fixing tool of the heat shield sheet is abbreviated as the hook-shaped fixing tool.

  As shown in FIG. 1, the hook-shaped fixing tool 20 is formed by bending a band-shaped metal plate having a thickness of several millimeters into an L shape, and an inner frame 50 ( 2 is formed in the groove of the grooved frame 30 (see FIG. 2) together with the heat shield sheet 10 (see FIG. 2), and the heat shield sheet 10 (see FIG. 2) is formed at the other end. ) In the groove is formed with a rotation operation piece 23 for rotating the fixing member 61 (see FIG. 2).

  The saddle-shaped fixing tool 20 has a width that is slightly smaller than the groove opening width of the groove-shaped frame 30 and a length that can be rotated with one hand. In addition, the site | part which cannot be inserted in the groove | channel of the groove-shaped frame 30 among the main-body parts 21 of a housing may be wide.

  The pressing piece 22 of the hook-shaped fixing tool 20 is a rectangular plate formed by bending the tip of the short piece 21a of the main body portion 21 of the L-shaped box and facing the direction in which the short piece 21a extends and substantially parallel to the long piece 21b. It has the composition which has. This rectangular plate has a rectangular shape that is long in the longitudinal direction of the long piece 21b, and its four corners are chamfered. As described above, the short side dimension of the rectangular plate is slightly smaller than the groove opening width dimension of the grooved frame 30, and the long side dimension is slightly smaller than the width dimension of the bottom 32 of the groove part 31 of the grooved frame 30. It is desirable. The long side may be longer.

  Moreover, the rotation operation piece 23 consists of a protruding piece formed by partially cutting off both ends in the width direction of the other end of the casing. In addition, this protrusion has a dimension corresponding to an operation groove 61a (see FIG. 7) of the fixing member 61 described later.

  Details of how to use the pressing piece 22 and the rotary operation piece 23 of the hook-shaped fixing tool 20 will be described in detail later with reference to FIGS.

  On the other hand, as shown in FIG. 2, the heat shield sheet 10 is a corrugated roof 1, and the on-roof fixture 3 is fixed to a connecting mountain portion 1 a obtained by connecting end portions of the roof material of the corrugated roof 1. In addition, the groove-shaped frame 30 is constructed thereon, and the heat shield sheet 10 is further attached thereon. The roof to be attached is not limited to the corrugated roof 1 and may be another roof.

  Although the details of the structure of the on-roof fixture 3 are not shown in the drawing, two clamping pieces 3a are combined, and two on the shaft portion of the connecting bolt body 2 protruding above the connecting peak portion 1a. The sandwiching piece 3a is sandwiched and fixed to the roof. The grooved frame 30 is structured to be fixed to the roof fixture 3 with screws. In FIG. 2, 3b is a fastening bolt that fastens two clamping pieces 3a and clamps them to the shaft portion of the bolt body 2, and 1b is a roof material support fitting (tight frame) for fixing with the bolt body 2. ).

  About the roof fixture 3, you may use the roof fixture of another structure. In addition, in the case of a roof in which the roof material is joined to the roof, a roof fixture that can be fixed to the roof portion is used, but the present invention is also applicable to those using such a roof fixture. It is.

  The groove-shaped frame 30 for fixing the heat shield sheet 10 is formed of a concave groove body made of metal or a hard synthetic resin (for example, FRP), and is wound around both end portions in the width direction of the opening of the groove portion 31. The reinforced lip portion 34 is formed.

  In order to fix and stretch the heat shield sheet 10 on the roof, in addition to the groove-shaped frame 30, an interior frame 50 having substantially the same cross section as the groove-shaped frame 30, and a rectangular shape with rounded corners. The fixing member 61, the long wave spring 62, and the frame cover 40 that closes the opening of the groove 31 are used. At both ends in the width direction of the frame cover 40, pressing pieces 41 for pressing the heat shield sheet 10 are formed. The frame cover 40 is fixed by passing the bottom portion 32 of the channel frame 30 and the top plate portion of the rooftop fixture 3 with screws S.

  The heat shield sheet 10 is sandwiched between the outer surface of the interior frame 50 and the groove inner surface of the grooved frame 30 in the groove of the grooved frame 30 as described above, so that the heat shield sheet 10 does not shift from the inside of the groove. It has a fixed structure that is pressed and fixed by 61 or a wave spring 62.

  Because of such a sandwiching structure, the interior frame 50 to be installed in the groove 31 of the grooved frame 30 has a bottom 52 that can be extended and bent in the width direction, and the opening flange piece 54 has the grooved frame 30. It is desirable that the groove is shaped so as not to be deformed so that it does not come off from the reinforcing lip 34. For example, an interior frame 50 made of a hard synthetic resin and having a plurality of staggered kerfs in the longitudinal direction in the bottom 52 so as to extend in the width direction may be used.

  On the other hand, the heat shield sheet 10 is made of a synthetic resin sheet that has flexibility and stretchability and reflects and blocks / insulates solar heat. For example, as shown in this embodiment, the heat shield sheet 10 reflects solar heat and the like. A fabric sheet formed by knitting a resin yarn material colored in silver or the like that cuts off and heat shields in length and breadth can be suitably used.

  The heat shield sheet 10 is fixed to a groove-shaped frame 30 fixed on the roof, and is stretched between the groove-shaped frames 30. In the present embodiment, the heat shield sheet 10 that is long in a band shape in a direction orthogonal to the grooved frame 30 is used. In addition, as shown in FIG. 3, the heat shield sheet 10 used in the present embodiment has a portion excluding both end portions 11 and 11 in the width direction (portions indicated by cross hatching) knitted with vertical and horizontal resin yarn materials. However, at both ends, the resin yarn material (weft 10a) is not fixed with the warp 10b (see a partially enlarged plan view surrounded by a one-dot chain line in FIG. 3).

  Next, a procedure for fixing and fixing the heat shield sheet 10 will be described with reference to FIGS.

  First, the heat shield sheet 10 is placed on the opening of the groove portion 31 of the groove-shaped frame 30, and the interior frame 50 is further placed thereon (see FIGS. 4 and 5).

  In this state, the pressing piece 22 of the hook-shaped fixing tool 20 is pushed into the groove of the interior frame 50 with the plate surface of the rectangular plate facing downward, and in this state, the interior frame 50 and the heat shield sheet 10 are arranged below. In this state, the bottom portion 52 of the interior frame 50 is deformed and is pushed into the groove of the grooved frame 30 and pushed in (see FIGS. 5 and 6).

  And after pushing in, the hook-shaped fixing tool 20 is once taken out in that state, and it presses with the pressing piece 22 similarly also in the other part of the longitudinal direction of the interior frame 50, and the whole interior frame 50 is carried out. It is attached to the groove 31 of the grooved frame 30.

  In order to mount the heat shield sheet 10 between the groove inner surface of the grooved frame 30 and the groove outer surface of the interior frame 50 without a gap, the rectangular plate is shortened while the pressing piece 22 of the hook-shaped fixing tool 20 is further rotated. It is desirable to press the side wall 53 of the groove 51 of the interior frame 50 at the side or corner. In order to facilitate the rotation operation in the groove of the pressing piece 22, it is desirable to chamfer the corner as shown in the figure.

  Thus, since the pressing piece 22 is formed at one end of the hook-shaped fixing tool 20, the interior frame 50 and the heat shield sheet 10 can be easily attached to the channel frame 30. That is, after attaching one end or the middle of the heat shield sheet 10 to the groove-shaped frame 30, when attaching the corresponding part of the heat shield sheet 10 to another adjacent groove-shaped frame 30, it is ensured with a strong force. Although it is necessary to maintain the tension, even in such a case, since the interior frame 50 and the heat shield sheet 10 can be pressed together, the heat shield sheet 10 can be stretched relatively easily. Further, since the heat shield sheet 10 is mounted together with the interior frame 50, the heat shield sheet 10 can be moved out of the groove if the opening flange piece 54 of the interior frame 50 is pressed from above with fingers until the subsequent fixing operation. There is no risk of coming off.

  The heat shield sheet 10 thus mounted on the groove frame 30 is fixed so as not to be displaced to the groove frame 30 by mounting the fixing member 61 described below into the groove.

  The fixing member 61 is made of a substantially rectangular flat plate made of synthetic resin or metal, and an operation groove 61a along the long side direction is formed at the center thereof. The operation groove 61a is preferably a through groove so that it can be used on both sides.

  Further, it is desirable that the dimension of the long side of the fixing member 61 is a dimension that can press the side wall 33 of the groove portion 31 of the grooved frame 30 at both short sides.

  First, such a fixing member 61 is dropped into a groove in which the heat shield sheet 10 is mounted together with the interior frame 50 (see FIG. 7).

  In this state, the rotary operation piece 23 of the hook-shaped fixing tool 20 is directed downward, the rotation operation piece 23 is inserted into the operation groove 61a of the fixing member 61 placed in the groove, and the fixing member 61 is laterally inserted in the inserted state. The two short sides are rotated until they come into pressure contact with the side wall 53 of the interior frame 50 in the groove (see FIGS. 7 and 8).

  Since the fixing member 61 has a structure in which both short sides press the side wall 53 of the interior frame 50 in the groove (the side wall 33 of the grooved frame 30), until the long side is orthogonal to the longitudinal direction of the grooved frame 30. By rotating, the fixing member 61 is press-fitted. As a result, the heat shield sheet 10 is sandwiched between the groove inner surface of the grooved frame 30 and the outer surface of the interior frame 50 and fixed.

  By attaching a plurality of such fixing members 61 in the width direction of the heat shield sheet 10, the heat shield sheet 10 is fixed to the groove portion 31 of the grooved frame 30 so as to be hardly displaced.

  After the heat shield sheet 10 is temporarily fixed in this manner, the wave spring 62 is further mounted in the groove 31 so that the crest 62a and the trough 62b press the side wall 33 of the groove 31 from the inside (see FIG. 9).

  In the state where the elastic force before the interior does not act, the wave spring 62 has a width dimension (twice the amplitude) from the peak portion 62a to the valley portion 62b larger than the width dimension (inner dimension) of the bottom portion 32 of the groove portion 31. It is formed and elastically deforms by being installed in the groove portion 31, and an elastic return force acts to further press the inner frame 50 toward the side wall 33 of the groove portion 31.

  After the heat shield sheet 10 is fixed to the groove-shaped frame 30 by pressing from the inside of the groove portion 31 in this way, the frame cover 40 is covered so as to hide the opening of the groove portion 31, and is grooved with screws S (drill screws or the like). It fixes to the shape frame 30 (refer FIG. 9).

  As described above, since the rotation operation piece 23 is formed at the other end of the hook-shaped fixing tool 20, the fixing member 61 can be rotated and the heat shield sheet 10 can be fixed to the grooved frame 30.

  In addition, since the hook-shaped fixing tool 20 includes both the pressing piece 22 and the rotation operation piece 23, the heat shielding sheet 10 is pressed by the heat shielding sheet 10 into the groove of the grooved frame 30 and the fixing member 61. Both fixing operations can be performed with a single tool. In addition, since it is a bowl-shaped simple tool, it is convenient to carry and can be used comfortably on the roof.

  Next, another example of the shape of the hook-shaped fixing tool of the present invention will be described with reference to schematic front views of the hook-shaped fixing tool shown in FIGS. In this figure, the detailed shapes of the pressing piece 22 and the rotary operation piece 23 provided on the hook-shaped fixing tool 20 are not shown, but one of X1, X2, X3 or Y1, Y2, Y3 in the figure is, for example, 1 is formed, and on the other side, for example, a rotation operation piece 23 shown in FIG. 1 is formed.

  The saddle-shaped fixing tool 20 in FIG. 10 (a) is formed in a U-shape, and a pressing piece 22 (see FIG. 1) is formed on either one of both end portions X1 and Y1, and the rotary operation piece 23 (see FIG. 1). 1) is formed. Since it is formed in a U shape in this way, it is convenient for handling and storage.

  The hook-shaped fixing tool 20 in FIG. 10 (b) is bent in two places and formed in a crank shape, and a pressing piece 22 (see FIG. 1) is formed in either one of the two end portions X2 and Y2, while the other A rotating operation piece 23 (see FIG. 1) is formed on the surface. Since it is formed in a crank shape in this way, when using one (for example, X2), the housing provided with the other (for example, Y2) can be used instead of the handle when rotating, so operability is good .

  10 (c) has three end portions X3, X3, and Y3, and a pressing piece 22 (see FIG. 1) is formed on each of the end portions X3 and X3 facing downward, and faces upward. A rotation operation piece 23 (see FIG. 1) is formed at the end. Thus, since the two pressing pieces 22 are provided in the same row, the heat shield sheet 10 (interior frame 50) can be pressed simultaneously at two locations, and the work can be speeded up. The hook-shaped fixing tool 20 may be formed by, for example, fixing a U-shaped casing and an L-shaped casing as shown in the figure.

  FIG. 11 is a partial perspective view showing another shape example of the pressing piece of the hook-shaped fixing tool.

  The pressing piece 22 is formed by attaching a separate plate body 22a to the tip of the main body 21 of the housing, and an insertion piece 21c provided at the front end of the main body 21 of the housing in the opening groove 22aa in the center of the plate 22a. Is inserted and caulked and combined. According to the pressing piece 22, since it is not a one-piece fold formation, the main body 21 of the housing can be formed in another shape (for example, a columnar body) that is easy to operate, and is a sturdy and easy-to-use hook-shaped fixing tool. 20 can be configured.

  12 (a) and 12 (b) are partial perspective views showing other examples of the shape of the rotary operation piece of the hook-shaped fixing tool.

  The rotation operation piece 23 shown in FIG. 12A is configured by two projecting pieces so that it can be mounted in the two operation holes 61 b provided in the fixing member 61. Further, the rotation operation piece 23 illustrated in FIG. 12B is configured by three projecting pieces corresponding to the three operation holes 61 b of the fixing member 61. In addition, in FIG.12 (b), the hook-shaped fixing tool 20 which formed the box in the columnar shape is illustrated.

  When the object to be inserted into the rotation operation piece 23 is formed by the operation groove 61a (see FIG. 7), the operation groove 61a is deformed (becomes ridiculous) by the rotation operation, and the rotation operation cannot be performed when remounting. Although there is a possibility, in the case where the plurality of operation holes 61b are configured, the possibility of being ridiculous is low, and repeated rotation operations can be withstood.

  Further, the rotation operation piece 23 may be configured by two sandwiching pieces so that the fixing member 61 can be rotated while sandwiching its short direction.
