Description

  The present invention relates to a surface lattice fixing bracket and a surface lattice fixing structure.

  A face grid may be attached to an opening frame of a building opening (for example, a window frame or a sash frame). For example, Patent Document 1 describes a structure in which a surface lattice is arranged outside a window by fixing an attachment device on the back of a surface lattice and attaching the attachment device to a sash. The mounting device of Patent Document 1 is composed of two mounting brackets and an intermediate bracket therebetween, and the distance between the sash and the surface lattice can be adjusted by adjusting the length and fastening with a fastener. .

However, in the attachment apparatus of the cited document 1, since the fastener is exposed to the outside, it does not look good. In order to improve the appearance, it is conceivable that the two mounting brackets and the intermediate bracket between them are completely integrated by welding or the like in advance in the factory or the like (no fastener is required). If it is integrated, the length cannot be adjusted.
JP 2003-20880 A

  In consideration of the above facts, the present invention has a surface lattice fixing bracket that can be adjusted in length and is excellent in appearance, and a surface lattice fixing structure that uses this surface lattice fixing bracket to attach a surface lattice to an opening frame of a building. It is a problem to obtain.

  The invention according to claim 1 is a surface grid fixing bracket disposed between an opening frame of a building opening and a surface grid attached to the opening frame by a mounting member to connect the opening frame and the surface grid. The opening frame has a uniform cross-sectional shape parallel to a surface grid mounting surface to which the surface grid is mounted, and the mounting member can be concealed in a state where the surface grid is mounted on the opening frame. It is characterized by being.

  This surface grid fixing bracket has a uniform cross-sectional shape in a cross section parallel to the surface grid mounting surface. That is, a uniform cross-sectional shape appears regardless of the cross-section. Therefore, the face grid fixing bracket can be cut at an appropriate position and adjusted to a desired length.

  Moreover, in this surface grid fixing bracket, the attachment member for attaching the surface grid to the opening frame of the building can be concealed in a state where the surface grid is mounted on the opening frame. Therefore, it is excellent in appearance.

  The face grid fixing bracket preferably conceals the entire mounting member, but even if only a part is concealed, the concealed portion cannot be seen from the outside so that the appearance can be improved.

  The “uniform cross-sectional shape” as used herein includes those having exactly the same cross-sectional shape, but can be disposed between the opening frame and the surface lattice. As long as the mounting member can be shielded, the cross sections may not be exactly the same. For example, a reinforcing member (rib or bead) may be partially protruded.

  According to a second aspect of the present invention, in the first aspect of the present invention, the mounting member includes guide means for guiding the mounting member from the surface lattice side to the opening frame side.

  Therefore, since the mounting member can be positioned by guiding the mounting member from the surface lattice side to the opening frame side by the guiding means, it is possible to reduce the work load of the surface lattice mounting work by the mounting member.

  The invention according to claim 3 is characterized in that in the invention according to claim 1 or 2, it has a reinforcing member attached so as to extend from the surface lattice side to the opening frame side.

  Since the surface grid fixing bracket is reinforced by the reinforcing member, the surface grid can be more reliably attached to the opening frame.

  In invention of Claim 4, the surface grid fixing bracket of any one of Claims 1-3 arrange | positioned between the opening frame of a building opening, and a surface grid, and a part are said surfaces. An attachment member which is concealed by a lattice bracket and attaches the surface lattice to the opening frame.

  That is, in this surface lattice fixing structure, the surface lattice fixing bracket according to any one of claims 1 to 3 is disposed between the opening frame of the building and the surface lattice. Therefore, the position (separation amount) of the surface grid with respect to the opening frame can be adjusted by adjusting the length of the surface grid fixing bracket.

  Moreover, although a surface lattice is attached to an opening frame by an attachment member, the attachment member is shielded by a surface lattice fixing bracket. Therefore, the appearance can be improved as compared with a structure in which the mounting member is not shielded.

  The invention according to claim 5 is characterized in that, in the invention according to claim 4, the attachment member is a through-fixing screw that penetrates the surface lattice fixing bracket from the surface lattice and is screwed into the opening frame. And

  That is, in the present invention, the attachment member is not particularly limited, but by using a through-fixing screw, the surface lattice can be reliably attached to the opening frame with a simple structure. In particular, the through-fixing screw penetrates the surface lattice fixing bracket from the surface lattice and is screwed into the opening frame, so the number of parts is small compared to the case of using a screw divided without penetrating in this way. Become.

  The invention according to claim 6 is the invention according to claim 5, wherein the through-fixing screw is made of high-hardness steel.

  Thereby, even after fixing, the surface lattice can be firmly attached to the opening frame, and the penetration fixing screw can be prevented from being broken carelessly.

  The invention according to claim 7 reinforces the surface lattice by being arranged in contact with the surface lattice from the opposite side of the surface lattice fixing bracket in the invention according to any one of claims 4 to 6. And a reinforcing plate.

  Because the reinforcement plate reinforces the contact area between the face grid and the face grid fixing bracket, for example, even when an external force is applied to the face grid, displacement and separation of the face grid with respect to the face grid fixing bracket can be suppressed. It becomes.

  In invention of Claim 8, in the invention of any one of Claims 4-7, the said surface lattice fixing bracket respond | corresponds to the waterproof member arrange | positioned between the said building and the said opening frame. It is characterized by being arranged in the position.

  Thus, by disposing the surface grid fixing bracket at a position corresponding to the waterproof member, the surface grid does not require a member for waterproofing. Compared to a configuration that requires a waterproof member, the number of parts is reduced.

  According to a ninth aspect of the present invention, in the invention according to any one of the fourth to eighth aspects, the strain is attached to at least one of the opening frame, the surface lattice, and the surface lattice fixing bracket. And a notifying means for notifying the occurrence of strain based on the strain detected by the strain sensor.

  Therefore, when the strain is detected by the strain sensor, this is notified by the notification means, so that the occurrence of strain can be known. For example, when a strain is generated due to an external force acting on the surface lattice, this can be known in a short time.

  Since the present invention is configured as described above, there is a surface grid fixing bracket that can be adjusted in length and is excellent in appearance, and a surface grid fixing structure that uses this surface grid fixing bracket to attach a surface grid to an opening frame of a building. can get.

  FIG. 1 shows a surface lattice fixing bracket 44 and a surface lattice 14 according to the first embodiment of the present invention. Further, FIG. 2 shows a surface lattice fixing structure 12 in which the surface lattice 14 is fixed to the building 16 via a surface lattice fixing bracket 44. Further, FIG. 3 shows an enlarged view of the vicinity of the surface lattice fixing bracket 44. In the drawing, the width direction of the surface lattice 14 is indicated by an arrow W, the upward direction is indicated by an arrow UP, and the inside direction of the building is indicated by an arrow IN.

  As shown in FIG. 2, the window 18 of the building 16 is provided with a sash frame 20 serving as the window frame. The surface lattice 14 is fixed to the outside of the sash frame 20 by a through-fixing screw 32 via a surface lattice fixing bracket 44. The outer surface of the sash frame 20 is a surface grid mounting surface to which the surface grid 14 is mounted via the surface grid fixing bracket 44.

  As shown in FIG. 1, the surface lattice 14 has a pair of lattice vertical frames 24 extending in the vertical direction, and a lattice horizontal frame 26 extending in the horizontal direction at the upper and lower portions of the lattice vertical frames 24. A square frame 22 is provided, and a plurality of horizontal bars 28 are spanned and attached to the lattice vertical frame 24 in the square frame 22. And in this embodiment, it is set as the structure where two surface grid fixing brackets 44 are used for the upper and lower sides with respect to one grating | lattice vertical frame 24, and the surface grating 14 whole.

  In the lattice vertical frame 24, one or a plurality of screw insertion holes 30 (see FIG. 2) are formed at predetermined positions (two in this embodiment for one surface lattice fixing bracket 44). The penetration fixing screw 32 is formed with a male screw 32M in the vicinity of the distal end portion, and is a so-called tex screw. Therefore, the male screw 32M is screwed from the sash frame 20 into the outer wall frame 34 of the building 16 in a state where the through fixing screw 32 is inserted (penetrated) into the screw insertion hole 30 and the surface lattice fixing bracket 44, thereby the surface lattice. 14 is fixed to the sash frame 20 (building 16).

  Moreover, the penetration fixing screw 32 is made of high hardness steel. Therefore, the hardness is higher than that of a screw made of a material that is not high-hardness steel, and resistance to cutting, breakage, and the like is high. Note that. Here, “high hardness” specifically refers to a material having a hardness HRC (Rockwell C scale) 56 or higher.

  As shown in FIG. 2, a water stop material 36 and a water stop sheet 38 are disposed between the sash frame 20 and the outer wall frame 34 constituting the building 16 so as to be sandwiched therebetween. The screw insertion hole 30 is formed at a predetermined position so that the through-fixing screw 32 penetrates the water-stopping material 36 and the water-stopping sheet 38, and positions (positions) the through-fixing screw 32.

  Screw insertion holes 40 are also formed in the lattice vertical frame 24 at positions between the screw insertion holes 30. As will be described later, the screw insertion hole 40 is inserted with a temporary fixing screw 42 for temporarily fixing the surface lattice fixing bracket 44 to the surface lattice 14. The temporary fixing screw 42 is a so-called tapping screw, and a male screw 42M is formed on the outer periphery.

  As shown in FIG. 3, the surface lattice fixing bracket 44 disposed between the lattice vertical frame 24 and the sash frame 20 has a square cylindrical bracket main body 46, and in the bracket main body 46. One or a plurality of intermediate plates 49 (in this embodiment, the upper intermediate plate 49U and the lower intermediate plate 49L are spaced apart in the vertical direction). Considering an arbitrary cross section in a direction orthogonal to the arrow IN direction (parallel to the surface grid mounting surface), the bracket body 46 and the intermediate plate 49 have substantially the same cross section. That is, a substantially uniform cross-sectional shape appears even when the surface grid fixing bracket 44 is cut at any position in the direction of the arrow IN.

  A screw guide 48 is formed along the direction of the arrow IN on the upper surface of the upper intermediate plate 49U and the lower surface of the lower intermediate plate 49L. The screw guide 48 is formed in a substantially “C” shape so as to surround the periphery of the penetration fixing screw 32 when viewed in the direction of the arrow IN, and the penetration fixing screw 32 is formed in the direction of the arrow IN, that is, from the surface lattice 14 side. When it is inserted into the 20 side, the penetration fixing screw 32 is guided. In particular, the screw guide 48 is formed inside the bracket body 46 and guides the penetration fixing screw 32 so as not to be exposed to the outside.

  A tapping hole 50 is formed in the lower surface of the upper plate 46U of the bracket body 46 and the upper surface of the lower plate 46L. The tapping hole 50 has an inner diameter portion slightly smaller than the outer diameter of the male screw 42M of the temporary fixing screw 42, and the male screw 42M cuts the inner surface of the tapping hole 50 when the temporary fixing screw 42 is screwed. While screwing.

  As shown in FIGS. 1 and 3, a reinforcing plate 52 is disposed outside the lattice vertical frame 24. The reinforcing plate 52 is disposed at a position corresponding to the surface lattice fixing bracket 44, that is, a position where the lattice vertical frame 24 is partially sandwiched between the surface lattice fixing bracket 44 and the reinforcing plate 52. Screw insertion holes 54 and 56 are formed in the reinforcing plate 52, and the penetration fixing screw 32 and the temporary set screw 42 are inserted through the reinforcing plate 52, respectively.

  As shown in FIG. 1, eye plates 58 are attached to the lattice vertical frame 24 and the lattice horizontal frame 26 from the outside. Further, caps 60 are attached to the upper and lower ends of the lattice vertical frame 24.

  Next, the method of fixing the surface lattice 14 to the building (sash frame 20) using the surface lattice fixing bracket 44 of the present embodiment and the operation of the surface lattice fixing structure 12 of the present embodiment will be described.

  When fixing the surface lattice 14 to the sash frame 20, first, as shown in FIG. 4A, the surface lattice fixing bracket 44 is cut at a predetermined cutting position CL on the construction site. That is, the distance from the sash frame 20 to the surface lattice 14 is variously set according to the type of building and the surface lattice 14, and in particular, in a structure that opens and closes the window by moving a window glass (not shown). It is also necessary to avoid interference between the surface grating 14 and the window glass (not shown). In the present embodiment, the bracket body 46 and the intermediate plate 49 have substantially the same cross section, and even if the surface lattice fixing bracket 44 is cut at any position in the direction of the arrow IN, a uniform (substantially the same) cross sectional shape is obtained. appear. Thus, by cutting the surface lattice fixing bracket 44 to a desired length, the surface lattice 14 can be fixed to the sash frame 20 while avoiding interference with the window glass or the like. There is no need to manufacture at a factory or transport to a construction site. In the state shown in FIG. 4A, caps 60 are attached to the upper and lower ends of the lattice vertical frame 24.

  Next, as shown in FIG. 4B, the surface lattice fixing bracket 44 and the reinforcing plate 52 are temporarily fixed to the surface lattice 14 with temporary fixing screws 42. Temporary fixing prevents the surface grid fixing bracket 44 and the reinforcing plate 52 from being inadvertently dropped or displaced from the surface grid 14, thereby improving the subsequent workability.

  Next, as shown in FIG. 4C, the surface lattice 14 is fixed to the sash frame 20 (not shown in FIG. 4, see FIG. 2) using the through fixing screws 32. The through-fixing screw 32 is inserted into the screw insertion hole 30 shown in FIG. 3 and is further guided by the screw guide 48 in the direction of the arrow IN. Therefore, the workability of the fixing work is improved and the position of the through-fixing screw 32, particularly the tip position screwed into the sash frame 20, as compared with the configuration without the screw guide 48 (the configuration in which the through-fixing screw 32 is not guided). Is positioned accurately.

  At this time, since the surface lattice fixing bracket 44 is cut to a desired length, the surface lattice fixing bracket 44 is fixed by penetration until the surface lattice fixing bracket 44 contacts both the sash frame 20 and the surface lattice 14 as shown in FIG. By screwing the screws 32, the surface lattice 14 is fixed at a predetermined position in the direction of the arrow IN.

  Further, as shown in FIG. 2, the position of the penetration fixing screw 32 is aligned with the position corresponding to the water stop material 36 and the water stop sheet 38 by the screw insertion hole 30. Thereby, since the water stop by the water stop material 36 and the water stop sheet | seat 38 is attained, the member for a water stop becomes unnecessary in the surface lattice 14, a number of parts decreases, and it becomes low cost. The operation | work which arrange | positions and attaches the member for water stop is also unnecessary, and work efficiency becomes high.

  In this state where the surface grid 14 is fixed to the sash frame 20, the through-fixing screw 32 is covered with the surface grid fixing bracket 44 and its periphery (shaft) is not visible from the outside. Therefore, the appearance is improved as compared with the configuration in which the shaft portion of the through-fixing screw 32 is exposed.

  Then, the eye plate 58 is attached to the square frame 22 as shown in FIG. Since the head plate 58 covers the heads of the through-fixing screw 32 and the temporary fixing screw 42 and the reinforcing plate 52, the appearance is further improved as compared with the exposed structure.

  Further, since the caps 60 are attached to the upper and lower ends of the lattice vertical frame 24, entry of foreign matter into the lattice vertical frame 24 is suppressed, and the appearance is further improved.

  In the state where the surface lattice 14 is fixed to the sash frame 20 in this way, the outside of the screw insertion hole 30, that is, the outside of the portion where the through fixing screw 32 is inserted into the surface lattice 14 is reinforced by the reinforcing plate 52. Yes. That is, the surface lattice fixing bracket 44 is attached to the surface lattice 14 via the reinforcing plate 52. Therefore, even when an external force (for example, a pulling force in the direction opposite to the arrow IN) is applied to the surface lattice 14, it is possible to prevent the through-fixing screw 32 from being accidentally pulled out from the screw insertion hole 30. For example, there is a high possibility that these can be restrained against the opening of the surface lattice 14 by a bar or the like, or the cutting of the lattice vertical frame 24 by a gold saw, a hammer or the like.

  Moreover, the penetration fixing screw 32 is made of high hardness steel. Therefore, the surface lattice 14 can be more firmly fixed. Furthermore, it is more likely that the penetration fixing screw 32 can be prevented from being cut or broken as compared with a material made of a material other than high-hardness steel.

  As described above, in the present embodiment, the surface grid fixing bracket 44 can be used after being cut to a desired length. Therefore, depending on the structure of the window glass or the like, for example, as shown in FIG. 5A, it is possible to further shorten the surface grid fixing bracket 44 and fix the surface grid 14 at a position close to the building 16. is there. Alternatively, as shown in FIG. 5 (B), when attaching the surface grid 14 to a window having a shoji that opens to the outside, such as a louver window, simply changing the cutting position of the surface grid fixing bracket 44 to make it longer, The surface grid 14 can be fixed at a position away from the building 16.

  5A and 5B show an example in which the four surface lattice fixing brackets 44 are cut to the same length, but the lengths of the surface lattice fixing brackets 44 are different. Good. For example, as shown in FIG. 5C, in the case of a structure in which the window glass 62 is opened obliquely, the surface grid fixing bracket 44 is made to have a different length so that the surface grid 14 is also inclined correspondingly. In addition, it may be cut obliquely. Furthermore, although illustration is omitted, even when there is a step on the surface to which the building-side surface grid fixing bracket 44 contacts, by cutting the surface grid fixing bracket 44 along with this step, it is possible to cope with the step. Is possible.

  5A to 5C, the through-fixing screw 32 having a length corresponding to the length of the surface lattice fixing bracket 44 is used. In any configuration, it is possible to cope with this by simply changing the lengths of the surface grid fixing bracket 44 and the through-hole fixing screw 32, and it is not necessary to manufacture the respective lengths of the surface grid fixing bracket 44.

  In the present invention, the surface lattice fixing bracket 44 can be made of the same material as the sash frame 20 and the surface lattice 14, and a material different from that of the sash frame 20 and the surface lattice 14 may be used. .

  FIG. 6 shows a surface lattice fixing structure 72 according to the second embodiment of the present invention. In the second embodiment, in addition to the configuration of the surface lattice fixing structure 12 of the first embodiment, a strain gauge 74, a notification unit 78, and the like are added. Hereinafter, components, members, and the like added as the second embodiment will be described, and the same components, members, and the like as those in the first embodiment will be denoted by the same reference numerals and detailed description thereof will be omitted.

  In the surface grid fixing structure 72 of the second embodiment, strain gauges 74 are attached to predetermined positions of the horizontal rail 28, the grid vertical frame 24 and the surface grid fixing bracket 44. These strain gauges 74 can detect the strain amount of the surface lattice 14 independently or from the mutual positional relationship.

  The strain gauge 74 is connected to the CPU 77 in the control device 76, and the obtained strain amount data is sent. Further, the CPU 77 is connected with an alarm speaker 80, an alarm light 82 and a communication terminal 84 as notification means 78.

  The control device 76 includes a main switch 86 and a reset switch 88. The main switch 86 is normally turned on, but in the off state, the operation of the entire control device 76 is stopped. On the other hand, the reset switch 88 is normally on, but when it is turned off, the operation of the notification means 78 is stopped.

  The surface lattice fixing structure 72 of the second embodiment configured as described above has the same effects as the surface lattice fixing structure 12 of the first embodiment, but further, as shown in the following flow, the surface lattice fixing structure 72 When an external force acts on 14 and distortion occurs, the CPU 77 performs a predetermined operation such as notifying this. Normally, as described above, the main switch 86 and the reset switch 88 are in an on state.

  In this flow, first, in step S12, it is determined from the strain amount data sent from the strain gauge 74 whether or not the displacement of the surface lattice 14 is outward. If the displacement of the surface lattice 14 is outward, it is determined in step S14 whether or not the load applied to the surface lattice 14 is an evenly distributed load. If the load is not a uniform load, it is determined in step S16 whether the time during which the strain is detected is a predetermined time set in advance. If each determination is negative in steps S12, S14, and S16, the process proceeds to step S24 to determine whether or not the main switch 86 is turned off. If the main switch 86 is not turned off, the process returns to step S12. If it is turned off, the process is terminated.

  Accordingly, when the displacement of the surface lattice 14 is outward, the load distribution is not an equal load distribution, and the strain detection time exceeds a predetermined time, the CPU 77 activates the notification means 78 in step S18. Specifically, an alarm sound is generated from the alarm speaker 80 and the alarm light 82 is turned on or blinked. Further, the communication terminal 84 communicates with a predetermined communication destination. Of course, it may be set in advance to perform any one of these processes according to the situation.

  Next, in step S20, it is determined whether or not the reset switch 88 is turned off. If the reset switch 88 is not turned off, the process returns to step S18 to continue the operation of the notification means 78. If the reset switch 88 is turned off, the operation of the notification means 78 is stopped in step S22. Then, the process proceeds to step S24.

  As described above, in the surface lattice fixing structure 72 of the second embodiment, the strain generated in the surface lattice 14 is detected by the strain gauge 74, and this is notified by the notification means, so that the occurrence of strain can be known in a short time. Can do.

  In addition, as a surface grating | lattice fixing bracket of this invention, it is not limited to what was demonstrated in said each embodiment, You may show to each following embodiment. In the following, only the shape of the surface lattice fixing bracket is different, but the overall configuration of the surface lattice fixing structure is the same as that of the first embodiment or the second embodiment, and thus detailed description thereof is omitted.

  FIG. 8 shows the surface grid fixing bracket 102 of the third embodiment. In the surface grid fixing bracket 102, two intermediate plates of an upper intermediate plate 49U and a lower intermediate plate 49L are formed in the bracket main body 46 with a predetermined upper and lower intervals as in the first embodiment. .

  A tapping hole 104 is formed on the lower surface of the upper plate 46U of the bracket body 46 and the upper surface of the lower plate 46L instead of the screw guide 48 of the first embodiment. Further, the tapping screw 108 is inserted into the screw insertion hole 30 of the lattice vertical frame 24 and then screwed into the tapping hole 104 instead of the through-fixing screw 32 of the first embodiment. Unlike the penetration fixing screw 32 of the first embodiment, the tapping screw 108 has a length that does not reach the sash frame 20.

  Tapping holes 106 are also formed on the upper surface of the upper intermediate plate 49U and the lower surface of the lower intermediate plate 49L. The tapping hole 106 extends from the middle portion in the longitudinal direction of the surface lattice fixing bracket 102 toward the back side (direction indicated by the arrow IN), and the tapping screw 110 can be screwed from the outside. The tapping screw 110 is formed to have a predetermined length so that the tip of the tapping screw 110 can be screwed into the sash frame 20 (see FIG. 2).

  Therefore, in the surface lattice fixing bracket 102 of the third embodiment, the screws (the through fixing screws 32 in the first embodiment) for fixing the surface lattice 14 to the sash frame 20 are divided into tapping screws 108 and 110. It will be.

  When the surface lattice 14 is fixed to the sash frame 20 using the surface lattice fixing bracket 102 of the third embodiment, first, the surface lattice fixing bracket is fixed to the sash frame 20 by the tapping screw 110. Thereafter, the surface lattice 14 is fixed to the surface lattice fixing bracket 102 with a tapping screw 108. Thus, in the surface lattice fixing bracket 102 of the third embodiment, it is possible to adopt a work procedure different from that of the surface lattice fixing bracket 44 of the first embodiment.

  Of course, also in the third embodiment, in the location where the tapping hole 106 is formed, substantially the same cross-sectional shape appears regardless of the position in the direction of the arrow IN when the surface grid fixing bracket 102 is cut. There is no need to manufacture the bracket at a factory or to carry it to the construction site.

  Further, since the tapping screws 108 and 110 are covered by the surface lattice fixing bracket 102, the appearance is improved as compared with the configuration in which these screws are exposed.

  FIG. 9 shows a surface grid fixing bracket 122 according to a fourth embodiment of the present invention. In the surface lattice fixing bracket 122 of the fourth embodiment, an upper intermediate plate 49U and a lower intermediate plate 49L similar to the surface lattice fixing bracket 102 of the third embodiment are formed in the bracket body 46.

  A reinforcing material guide 124 is formed on the lower surface of the upper plate 46U of the bracket main body 46 and the upper surface of the lower plate 46L, and the reinforcing material 126 is accommodated in the reinforcing material guide 124.

  The reinforcing material 126 is formed in a columnar shape (linear shape) by high hardness steel similar to the through-fixing screw 32 of the first embodiment. And in the state accommodated in the reinforcing material guide 124, the longitudinal direction (extending direction) of the reinforcing material 126 coincides with the longitudinal direction of the surface lattice fixing bracket 122.

  In the surface lattice fixing bracket 122 of the fourth embodiment configured as described above, the screw insertion holes 30 (see FIG. 3) of the lattice vertical frame 24 are inserted, similarly to the surface lattice fixing bracket 44 of the first embodiment. The through-fixing screw 32 penetrates through the surface grid fixing bracket 122, and the male screw 32M at the tip is screwed into the sash frame 20.

  Further, in the surface grid fixing bracket 122 of the fourth embodiment, since the reinforcing material 126 is disposed along the longitudinal direction of the surface grid fixing bracket 122, the surface grid fixing bracket 122 is reinforced as a whole. For example, the possibility of being able to suppress the cutting or breaking of the surface lattice fixing bracket 122 is higher than that in the configuration in which the reinforcing material 126 is not used.

  In the fourth embodiment, the positions of the penetration fixing screw 32 and the reinforcing material 126 may be interchanged. Moreover, in 4th Embodiment, workability | operativity may be improved by enabling it to temporarily fix to the surface lattice 14 with the temporary fixing screw 42 similarly to 1st Embodiment.

  In the above description, the through fixing screw 32 and the tapping screws 108 and 110 are given as the attachment members of the present invention. However, if the surface lattice 14 can be attached to the opening frame (sash frame 20) of the building, the attachment members are attached. The member is not limited to these. For example, nails, rivets and anchors may be used.
