Description

  The present invention relates to a window crack protection device for protecting a window glass or the like from being broken by a side pressure of accumulated snow in a snowy area.

  In heavy snow areas, the snow falls down to the height of the window, and the windshield is broken by the side pressure of the snow. Conventionally, as a countermeasure against such damage, a frame is constructed with a wooden frame at a position slightly away from the window glass, and a wooden board or corrugated sheet (made of vinyl chloride or metal, etc.) is built around it. It is done to stretch around. In addition, it was necessary to remove these frames and the like when it was not snowing.

  However, these operations are all performed by the residents of the house from the purchase of materials, and are not possible for anyone but difficult for the elderly. And it was a labor-intensive work for everyone. In addition, when wooden boards and corrugated boards were installed, there was a problem that the room could not be well lit and the interior of the room became dark all day.

  Further, Patent Document 1 discloses a protective material that prevents the window glass from being damaged by attaching the metal fitting (2) to the sash (4) of the window frame and screwing the horizontal plate (1) thereto. According to this protective material, it is said that damage to the window glass can be prevented (claim 1 of the utility model claim of patent document 1, paragraphs [0004] and [0005] of the specification, figure of the drawing) 3, see FIG.

  However, the protective material for preventing breakage of the window glass of Patent Document 1 has a problem that the side pressure of snow directly acts on the sash, and the window frame itself may be damaged by the pressure. In addition, this protective material has a problem that it is necessary to screw both ends of the horizontal plate (1), the number of members to be attached is large, and it is not easy to attach and detach the protective material. In addition, although this protective material has a slit for daylighting, it does not get enough light, it is difficult to see from the window and there is a psychological feeling of pressure and the inside of the room becomes dark all day There was a problem.

  Further, in Patent Document 2, mounting members (9, 10) are screwed to upper and lower walls of a window (window portion 2), and a lattice (upper support member 4, lower support member) is attached to the mounting members (9, 10). 5, a snow enclosure member to which a rod 8) is detachably attached is disclosed. According to this snow enclosure member, it can be easily attached and detached from the inside, and the light of the window portion is not blocked as much as possible, and the impact of snow can be surely prevented.

  However, since the mounting member (9, 10) that supports the lattice is attached to the wall in the snow enclosure member of Patent Document 2, there is a risk that the mounting portion of the wall may be damaged by snow load (snow side pressure). There is a problem that is high. In addition, since this snow enclosure member is a lattice, although it can take daylight from the window, snow falls through the lattice and accumulates around the window such as the lower support member (5), and when opening the window by ventilation etc., There is a problem that the accumulated snow enters the room. In addition, the snow fence member has a problem in that a plurality of rods (8) must be attached and detached for each window, and the number of parts is large and time-consuming.

  Hereinafter, an embodiment for carrying out a window crack protection device to which the present invention is applied will be described in detail with reference to the drawings.

[First Embodiment]
First, a window crack protection device B1 according to a first embodiment, which is an embodiment to which the present invention is applied, will be described with reference to FIGS.

  The window crack protection device according to the present invention is installed in a window on the ground floor of a house, and is not installed for each window, but basically for each continuous wall over the entire wall surface. It is provided. For this reason, in this Embodiment, the case where it installs over the whole wall W of the one surface with the first floor which is the ground floor of a two-story wooden house is demonstrated and demonstrated.

  As shown in FIGS. 1 to 9, the window crack protection device B <b> 1 according to the first embodiment includes an upper support member 21 and a lower support member 31, and a plurality of panels 41 spanned up and down on these, It has a function of protecting the house window W1 from being broken by the accumulated snow side pressure.

(Upper support member)
The upper support member 21 includes a wall surface side flat plate portion 211 that is installed substantially vertically along the wall W of the house, and an inclined portion 212 that is in contact with the wall surface side flat plate portion 211 along the longitudinal direction and is inclined downward. The panel-side flat plate portion 213 is connected to the inclined portion 212 along the longitudinal direction and descends substantially vertically. The upper support member 21 is installed along the wall W above the window W1 on the first floor with the horizontal direction (the direction opposite to Y in the figure) as the longitudinal direction, and has a function of fixing the upper portion of the panel 41. Yes. The horizontal direction mainly means the horizontal direction, and is used for the purpose of including the case where it is slightly inclined up and down.

  Each of the wall surface side flat plate portion 211, the inclined portion 212, and the panel side flat plate portion 213 is formed of a rectangular steel plate that is long in the lateral direction and has a length corresponding to the width of the wall W to be attached. The side flat plate portion 211 is 4.5 mm thick, and the inclined portion 212 and the panel side flat plate portion 213 are 3.2 mm thick.

  In addition, the panel-side flat plate portion 213 has a latching protrusion T1 that latches (hangs) the upper portion of the panel 41 in the horizontal direction at a predetermined interval in the lateral direction (forward and reverse directions of Y in the figure). It protrudes perpendicularly to the plate surface so as to protrude. As shown in the figure, the latching protrusion T1 has a shape in which a sphere having a diameter larger than the diameter of the shaft is attached to the tip of the shaft, and has a tip portion T1a and a shaft portion T1b.

  Since such an upper support member 21 fixes the upper part of the panel 41, it is necessary to firmly fix the panel 41 so that the panel 41 can withstand even if it is blown by wind. For this reason, the upper support member 21 is provided along a horizontal member that is a structural material such as a beam, girder, or trunk difference of a house, and an anchor that is driven into a hole formed in the horizontal member at a predetermined interval. And the wall surface side flat plate portion 211 are attached to the wall W by bolting. In addition, since the hole of an anchor is drilled from the outer side of the wall W, it is preferable to perform waterproofing around the anchor so that rainwater does not enter the horizontal member, such as sealing.

(Lower support member)
The lower support member 31 is a general L-shaped angle (for example, 6 mm thick × 50 mm × 50 mm) having a length corresponding to the width of the wall W to be attached, and includes a horizontal portion 311 and a vertical portion 312, and the horizontal portion 311. Is laid along the ground G. The lower support member 31 is supported and fixed to the ground G by anchoring or bonding the horizontal portion 311 to a concrete secondary product laid on the ground G such as a concrete block or a concrete flat plate. Needless to say, the horizontal portion 311 may be fixed to a floor plate made of concrete or the like directly placed on the ground G, such as a dog run or a floor tile, instead of a concrete secondary product.

  The vertical portion 312 of the lower support member 31 is formed with a horizontally long oblong hole 313 that is substantially horizontal along the ground G, and the lower portion of the panel 41 is bolted to the lower support member 31 through the oblong hole 313. Be joined. As described above, since the mounting structure has some play in which the lower part of the panel 41 is bolted through the long hole 313, the upper support member 21 and the lower support member 31 are not installed in parallel. In addition, the panel 41 can be easily fixed to the lower support member 31.

(panel)
The panel 41 includes a panel body 410 made of a folded plate formed by bending a rectangular steel plate vertically and vertically such as a galvalume steel plate into a mountain shape near the center of the horizontal section, and the panel body 410 has a predetermined width ( In this embodiment, it is 266 mm), and has a length that can be bridged up and down between the upper support member 21 and the lower support member 31, the left edge portion 411, the right edge portion 412, And a central mountain portion 413. The panel 41 is installed side by side to protect the window W1 from being broken by the accumulated snow side pressure, and by covering the area from the ground G to the top of the window W1, snow falls around the window. It has a function to prevent accumulation.

  The panel 41 has an upper portion 41 a hooked (hanged) on the upper support member 21, and a lower portion 41 b bolted to the lower support member 31. They are arranged side by side with an interval A in the lateral direction (the forward and reverse directions of Y in the figure) so that the protruding side is the outside. This interval A is a predetermined interval at least so that hands can enter and accumulated snow does not enter. In this embodiment, the interval A is about 25 mm.

  Thus, by providing the interval A in the installation of the panel 41, an opening for daylighting can be secured and the interval A can be handled, so that it is not necessary to slide the intervals when arranging them side by side. Easy to install. Moreover, the number of required panels can be reduced by this space | interval, and installation cost can also be reduced.

  Further, a pair of left and right latching holes H1 that are latched by the latching protrusion T1 of the upper support member 21 are formed in the vicinity of the upper ends of the left edge part 411 and the right edge part 412 that are the upper part 41a of the panel 41. ing. Each retaining hole H1 is a reverse key hole-like hole in which a long hole having a diameter smaller than the diameter of the circular hole communicates with the upper part of the circular hole, and a main hole H1a which is a circular hole having a large diameter. And a long hole portion H1b which is a long hole.

  Further, in the vicinity of the lower ends of the left edge portion 411 and the right edge portion 412 that are the lower portion 41b of the panel 41, a long hole N1 for bolt insertion for bolting to the lower support member 31 is formed. This long hole N1 is a long hole that is long in the vertical direction along the left and right edges of the panel 41, and since there is play in the vertical distance, coupled with the function of the long hole 313 having play in the horizontal direction, Even when the installation of 41 is poor, the panel 41 can be easily fixed to the lower support member 31.

  In addition, when it is desired to obtain more light from the window W1 in the room, the panel 41 may be formed of a transparent or translucent plate material such as an acrylic plate or a polycarbonate plate instead of a steel plate. Moreover, you may comprise the panel 41 from a perforated folded plate with holes, such as punching metal.

(Attachment structure to the upper support member of the panel)
Next, the attachment structure to the upper support member 21 of the panel 41 of the window crack protection apparatus B1 which concerns on 1st Embodiment is demonstrated in detail. The panel 41 is attached to the upper support member 21 by attaching the left edge portion 411 and the right edge portion 412 of the panel 41 to two adjacent latching protrusions T1 protruding from the panel side flat plate portion 213 of the upper support member 21. This is done by latching a pair of left and right latching holes H1 drilled near the upper end.

  As a specific procedure, a person such as a resident who installs the window cracking protection device B1 holds the lower portion 41b of the panel 41, and uses a retaining hole H1 provided in the upper portion 41a of the panel 41 that is self-supporting from the ground. It is carried out by hooking on the latching protrusion T1 of the upper support member 21 installed along the wall W above W1.

  The latching hole H1 is latched to the latching protrusion T1 by holding the lower portion 41b of the panel 41 in the hand and the leading end T1a having the large diameter of the latching protrusion T1 to the main hole H1a of the latching hole H1. When the shaft portion T1b is passed, the panel 41 is released. Then, the panel 41 falls by its own weight, and the long hole portion H1b of the latching hole H1 comes into contact with the shaft portion T1b of the latching projection T1. As a result, the tip end portion T1a of the latching protrusion T1 cannot pass through the long hole portion H1b, and the upper portion 41a of the panel 41 is latched and fixed to the upper support member 21.

  According to such an attachment structure of the panel 41 to the upper support member 21, since the panel 41 can be attached and detached from the ground while holding the lower part 41b of the panel 41 in hand, it is easy without performing a stepladder work or an altitude work. In addition, the upper portion 41a of the panel 41 can be attached and detached.

  In addition, the relationship between the latching protrusion T1 and the latching hole H1 may be reversed. In other words, the latching protrusion T1 may be provided on the left edge 411 and the right edge 412 of the upper part 41a of the panel 41, and the latching hole H1 may be provided in the panel side flat plate part 213 of the upper support member 21. . However, the hooking hole H1 needs to be provided upside down as shown in FIG. This is because a resident or the like can hold the lower portion 41b of the panel 41 in his hand and easily hang the panel 41 on the upper support member 21 from the ground even with the reverse configuration.

  Further, the panel 41 may be attached to the upper support member 21 by attaching the panel 41 to the inner side of the upper support member 21, that is, the wall side of the panel side flat plate portion 213 (in the X reverse direction in the figure). When attaching in such a manner, it is somewhat difficult to attach, but the rain of the upper portion 41a of the panel 41 is improved, and there is no possibility that snow accumulates.

  In addition, the attachment of the panel 41 to the upper support member 21 has been described by exemplifying the case in which the latching protrusion T1 and the latching hole H1 are latched, but either one of the panel and the upper support member is made of a ferromagnetic material. A metal member may be provided, a permanent magnet may be provided on the other side, and these may be joined by magnetic force. That is, it is sufficient if the panel is locked to the upper support member. Here, the term “locking” refers to the fact that both members are engaged and fixed wider than the hooking (latching).

(Attachment structure to the lower support member of the panel)
Next, the attachment structure to the lower support member 31 of the panel 41 of the window crack protection apparatus B1 which concerns on 1st Embodiment is demonstrated in detail. The panel 41 is attached to the lower support member 31 by bolting the lower portion 41 b of the panel 41 to the lower support member 31.

  Specifically, a resident or the like pierces the left edge portion 411 of the lower portion 41 b of the panel 41, the long hole N1 formed near the lower end of the right edge portion 412, and the vertical portion 312 of the lower support member 31. A hexagonal bolt of about M3 is inserted into the provided long hole 313, a washer is engaged, and the bolt is joined by tightening with a nut.

According to such a structure for attaching the panel 41 to the lower support member 31, the attachment to the lower support member 31 of the lower portion 41b of the panel 41, which has a high snow side pressure and is easy to work from the ground, can be easily and firmly fixed. Since it can be done by bolting, which is a method, it is possible to reliably restrain and fix the movement of the panel in the lateral direction, and prevent the panel from being unintentionally removed by the resident, such as being blown by the wind Can do. The side pressure (snow load in the lateral direction) during snowfall is approximately 800 N / m ² when snow is 2 meters, although it depends on the snow quality. There can be problems with sex.

  Note that the panel 41 may be attached to the lower support member 31 by clamp bonding in which the left edge portion 411 and the right edge portion 412 of the lower portion 41b of the panel 41 are clamped to the vertical portion 312 of the lower support member 31 with a clamp. I do not care. This is because with such a configuration, the same operational effects as described above can be achieved.

(Function and effect of the window crack protection device B1)
As described above, according to the window crack protection device B1 according to the first embodiment, the lower portion 41b of the panel 41 having a high snow side pressure can be supported on the ground G via the lower support member 31, so that There is little possibility that the wall will fall down due to the side pressure, and it is possible to reliably prevent the window from cracking.

  Further, according to the window crack protection device B1 according to the first embodiment, the window W1 is covered with the panel 41 having a certain width at a distance A in the lateral direction, so that the number of parts can be reduced. The work efficiency is improved and the window crack protection device can be easily installed.

  The panel 41 according to the first embodiment has been described as an example of a folded plate having no opening, but a net body such as a fence material or an expanded metal, a plate material having an opening such as a punching metal, or the like is bent. It may have a predetermined rigidity. By providing an opening in the panel, there is a possibility that snowfall may enter, but lighting can be taken from the opening.

  As described above, the window crack protection device B1 according to the first embodiment has been described by exemplifying the case where the entire surface is installed on the wall W. However, the present invention can be established even if the window W1 is installed for a certain width. Needless to say.

[Second Embodiment]
Next, a window crack protection device B2 according to a second embodiment, which is an embodiment to which the present invention is applied, will be described with reference to FIGS. The window crack protection device B1 according to the first embodiment has almost the same functions and the like, and only the specific configuration of each member is different. Therefore, the differences will be mainly described, and the same configuration will be the same. Reference numerals are assigned, and descriptions of functions and the like of members having the same name are omitted.

  As shown in FIGS. 10 to 14, the window crack protection device B <b> 2 according to the second embodiment includes an upper support member 22, a lower support member 32, and a plurality of panels 42 that are spanned up and down. Yes.

(Upper support member)
The upper support member 22 has substantially the same configuration as the upper support member 21 described above, and includes a wall surface side flat plate portion 221, an inclined portion 222, and a panel side flat plate portion 223, and is different from the upper support member 21 in that A latching hole H2 for latching a latching protrusion T2 described later is formed in the inclined portion 222 and the panel-side flat plate portion 223.

  This latching hole H2 is a T-shaped hole in plan view, and a latching part H2a which is a long hole along the wall surface of the wall W formed on the building side, and a length perpendicular to the latching part H3a. It consists of the shaft insertion part H2b which is a hole. Two adjacent latching holes H2 form a pair, and these latching holes H2 have a function of latching the pair of left and right latching protrusions T2.

(Lower support member)
As shown in FIG. 11, the lower support member 32 has a length corresponding to the width of the wall W to be attached, and has a main body 320 made of a square steel pipe having a rectangular section of 125 mm × 40 mm having a thickness of 2.3 mm. The side surface which becomes the short side of the rectangular cross section of the main body 320 is attached along the outer surface of the foundation F of the house by post-construction anchoring, adhesion, or the like (see also FIG. 14).

  The lower support member 32 is formed with a horizontally long oblong hole 323 formed along the ground G, which is substantially the same shape as the oblong hole 313. The lower portion 42b of the panel 42 is formed through the oblong hole 323. Is bolted to the lower support member 32.

(panel)
As shown in FIG. 12, the panel 42 includes a panel main body 420 processed into a U-shaped cross section from a general structural steel sheet having a thickness of about 2 mm subjected to hot dip galvanization. And a predetermined length that can be bridged up and down between the upper support member 22 and the lower support member 32.

  The panel 42 is formed with a plurality of long holes SH having a width of about 25 mm for daylighting. However, the upper limit of the aperture ratio of the panel 42 is 90%. This is because if the opening ratio of the panel 42 exceeds 90%, snow permeates due to the side pressure of the snow and the function as the window crack protection device B2 may not be achieved. Here, the aperture ratio is the ratio of the area of the vertical surface area between the upper support member and the lower support member that is not covered by the panel in the horizontal direction, that is, the horizontal ray on the vertical surface. This means the total area of the transmitting parts, and includes openings due to the spacing between the panels.

  In addition, as shown in FIGS. 12 and 13, a pair of left and right hooks that are latched in the latch holes H <b> 2 of the upper support member 22 are provided on the wall side (in the direction opposite to X in the figure) near the upper end of the panel body 420. A latching projection T2 is provided to project. As shown in the partial enlarged view in the broken-line circle in FIG. 12, the latching projection T2 has a shape in which a disk is suspended from the tip of the shaft, and has a disk portion T2a and a shaft portion T2b. Yes.

  As shown in FIG. 13, the upper portion 42a of the panel 42 is hooked (latched) on the upper support member 22, and the lower portion 42b of the panel 42 is bolted to the lower support member 32 as shown in FIG. They are arranged side by side with an interval A in the lateral direction.

(Attachment structure to the upper support member of the panel)
Next, the attachment structure to the upper support member 22 of the panel 42 of the window crack protection apparatus B2 which concerns on 2nd Embodiment is demonstrated in detail using FIG. The panel 42 is attached to the upper support member 22 in such a manner that a pair of left and right latching protrusions T2 and T2 projecting on the wall side of the upper part 42a of the panel 42 are formed in the two latching holes H2 connected to the upper support member 22. It is done by hanging.

  As a specific procedure, a person such as a resident who installs the window cracking protection device B2 holds the lower part 42b of the panel 42, and attaches the latching projection T2 provided on the upper part 42a of the panel 42 from the ground to the window W1. The upper part of the upper support member 22 installed along the wall W is inserted into the retaining hole H2, and a resident or the like releases the lower part 42b.
