Description

  The present invention relates to a structure of an opening of a building using a lightweight cellular concrete panel, and more particularly to a structure of an opening that does not hinder the locking function of the lightweight cellular concrete panel.

  In a building in which an outer wall is configured using a lightweight cellular concrete panel, an opening such as a window is generally configured on the outer wall using a sash. In this opening, there is an opening reinforcing material composed of a vertical member having a length corresponding to the distance between the upper and lower beams and a cross member having a length corresponding to the widthwise dimension of this opening. Is done. A lightweight cellular concrete panel is disposed around the opening reinforcement, and the upper end of the lightweight cellular concrete panel disposed below the lower cross member, the lower end of the lightweight cellular concrete panel disposed above the upper lateral member, Are attached to the lower cross member or the upper cross member through predetermined hardware, respectively. The lightweight cellular concrete panels arranged on both sides of the vertical member are attached to the upper and lower beams, respectively. The lightweight cellular concrete panel attached around the opening reinforcing material in this way, for example, when the upper and lower beams move relatively in the horizontal direction at the time of an earthquake, inclines starting from the attachment point along with this movement Has a locking function.

  And the sash which comprises a window, for example is arrange | positioned in the square space formed of the vertical member and the horizontal member of the opening reinforcement material, and the draining plate is attached to the lower frame of this sash. The sash frame disposed in the opening is fixed using a vertical member constituting the opening reinforcing member, a stay provided on the lower cross member, and a wooden opening frame formed on the indoor side. When the sash disposed in the opening is fixed in this manner, a gap is formed between the lower frame constituting the sash and the lower cross member of the opening reinforcing material. For this reason, the sash frame and the lower cross member of the opening reinforcing member are integrated and stabilized by filling the gap with mortar.

  On the other hand, by arranging the outer surface of the sash frame behind the surface of the outer wall, the design is improved by giving the opening a sense of depth (see, for example, Patent Document 1). In the invention described in Patent Document 1, a ridge is formed along the surface side at the fore end of the lightweight cellular concrete panel disposed around the opening, and a sash frame is disposed on the back side of the ridge. Has been. In other words, the sash frame is retracted to the indoor side by the size of the protrusion formed on the surface side of the lightweight cellular concrete panel, and a sufficient depth can be given.

  In the opening structure described in Patent Document 1, the opening reinforcing material composed of vertical members (vertical frame) and horizontal members (upper frame, lower frame) is a lightweight cellular concrete panel disposed on both sides of the opening. It is arrange | positioned at the back surface side of the protrusion formed in the fore edge. For this reason, when attaching a sash to an opening reinforcement, the draining plate attached to the lower frame of a sash will interfere with a protrusion. For this reason, the notch part for arrange | positioning a draining plate and a sealing material in a protrusion is formed.

  In the above-described conventional technique and the technique described in Patent Document 1, after fixing the sash frame arranged in the opening, when the mortar is filled in the gap formed between the lower cross member and the mortar, Usually, it is filled only between the sash frame and the lower cross member. However, depending on the state of the mortar, it may exist across the joints of the lightweight cellular concrete panels due to the fluidity of the mortar. During an earthquake, the mortar may resist and suppress the smooth rocking of lightweight cellular concrete panels.

  The object of the present invention is a structure in which a drained dish plate is inserted into a notch formed in a small opening of a lightweight cellular concrete panel, and a filler is filled in a gap formed between a lower cross member of an opening reinforcing material and a sash frame. An object of the present invention is to provide a structure of an opening of a building and a construction method that do not hinder the locking function of the lightweight cellular concrete panel even if the structure is filled.

  In order to solve the above problems, the structure of the opening of the building according to the present invention is the structure of the opening of a building configured using an opening reinforcing material and a sash made of lightweight cellular concrete panels, vertical members and cross members. And a small edge of the lightweight cellular concrete panel disposed beside the opening so as to avoid a drained plate attached to the lower frame of the sash and to secure a sealing dimension. The lightweight cellular concrete is filled with a notched part formed in the notch part and a filling material disposed between the lower cross member of the opening reinforcing member and the lower frame of the sash disposed corresponding to the notch part. And a blocking member that blocks contact with the panel.

  In the structure of the opening of the building, it is preferable that the blocking member has at least approximately the same dimension as the lateral dimension of the notch formed in the small edge of the lightweight cellular concrete panel.

  Moreover, in the structure of the opening part of any of the above-mentioned buildings, it is preferable that the blocking member has elasticity.

  Moreover, in the structure of the opening part of any of the above-mentioned buildings, it is preferable that the blocking member serves as a backup material for sealing applied on the outdoor side of the lightweight cellular concrete panel.

  The building opening construction method according to the present invention is a construction method for forming an opening of a building using an opening reinforcing material and a sash made of a lightweight cellular concrete panel, a vertical member and a cross member, and comprising a lightweight cellular A notch portion processing step for forming a notch portion so as to ensure a sealing dimension by avoiding a water drainage plate attached to the lower frame of the sash at the upper portion of the lower cross member of the opening reinforcing material at the edge of the concrete panel; Prior to attaching the drainage plate to the lower frame of the opening reinforcing member constituting the opening of the building and attached to the lower frame of the sash, the notched portion formed in the small edge of the lightweight cellular concrete panel A blocking member disposing step of disposing a blocking member that prevents the filler from entering the cutout portion and coming into contact with the lightweight cellular concrete panel; and a cut formed in the small edge of the lightweight cellular concrete panel. Between the bottom plate of the opening reinforcing material and the lower frame of the sash, And a filling filling step of filling a filling containing mortar.

  In the structure of the opening of the building according to the present invention (hereinafter, simply referred to as “opening” or “opening structure”), a sealing plate is secured by avoiding a drained dish plate at least in the width direction of the opening. In the opening portion where the lightweight cellular concrete panel (hereinafter referred to as “ALC panel”) having a notch portion is disposed, a blocking member is disposed corresponding to the notch portion, so that the lower cross member of the opening reinforcing material and the sash When the filling is filled in the gap formed between the lower frame and the filling, the filled filling does not enter the notch and does not contact the ALC panel. For this reason, the ALC panel and the opening reinforcing material are not integrated, and the locking function of the ALC panel is not hindered.

  In addition, since the blocking member has at least approximately the same dimension as the lateral dimension of the notch formed in the edge of the ALC panel, the filling is filled between the lower lateral member of the opening reinforcing material and the lower frame of the sash. An object can be prevented from entering the notch and coming into contact with the ALC panel.

  In addition, when the blocking member is made of an elastic body, even if the filler is densely filled in the gap formed between the lower cross member of the opening reinforcing member and the lower frame of the sash, the elasticity of the ALC It is possible to absorb the deformation at the time of rocking.

  Moreover, since the blocking member is a molding material, it can be attached by installing it with an adhesive tape or the like corresponding to the notch. For this reason, it is possible to prevent the filler from entering the cutout portion and coming into contact with the ALC panel with a simple operation. Furthermore, when the blocking member also has a function as a sealing backup material, the construction becomes easy.

  Moreover, in the construction method of the opening according to the present invention, the notch portion can be formed in the edge of the ALC panel at the notch portion processing stage, and the blocking member can be attached corresponding to the notch portion at the blocking member arrangement stage. A draining plate can be installed in the notch portion to which the blocking member is attached in the draining plate attaching step, and the filling can be filled in the filling step. At this time, since the blocking member is already attached corresponding to the notch, it is possible to prevent the filler from entering the notch and contacting the ALC panel.

  Hereinafter, the most preferable form of the opening structure according to the present invention will be described. The opening structure according to the present invention is configured by using an ALC panel in which a cutout portion for receiving a water draining plate is formed in a forehead, an opening reinforcing material configured by combining vertical members and cross members, and a sash. Is. Then, by disposing a blocking member corresponding to the notch portion of the ALC panel, when the filler containing mortar is filled in the gap between the lower frame of the sash and the lower cross member of the opening reinforcing material, It is configured such that it can be prevented from entering the notch and contacting the ALC panel.

  In particular, the blocking member is an elastic body having at least the same dimension as the lateral dimension of the notch, and the sealing work can be smoothly performed by exerting a function as a backup material for the sealing. Is.

  In the present invention, the shape of the edge of the ALC panel is not particularly limited, and any shape can be applied as long as a notch for inserting and arranging a draining plate is formed in the edge. As such an ALC panel, as described in Patent Document 1, there is one in which a protrusion is formed along the surface side.

  The opening reinforcing member is configured by combining a vertical member and a cross member. The dimensions of these vertical members and cross members are set according to the structure of the target building and the dimensions of the opening. That is, the length of the vertical member is set corresponding to the dimension between the upper and lower beams, and the length of the cross member is set corresponding to the width dimension of the opening. And it is comprised by arrange | positioning and fixing a cross member between the vertical members in the vertical position of the opening part in a wall surface, and the position corresponding to the height dimension of an opening part.

  The number of vertical members and cross members that constitute the opening reinforcing material is not limited, and a pair of cross members or single cross members that face each other in a similar manner are used. In the case of being composed of a material, there are also cases in which either a longitudinal material or a transverse material is composed of a pair of materials facing each other and the other is composed of a single material.

  The cross-sectional shape and dimensions of the members constituting the opening reinforcing material are not particularly limited, and it is preferable to set the cross-sectional shape and dimensions corresponding to the functions expected of the opening reinforcing material. For example, when the opening reinforcing member is expected to have a function of supporting the ALC panels arranged above and below the opening, at least the cross member uses angle steel, the lower cross member has the L-shaped portion downward, and the upper cross member has The L-shaped part is arranged upward and is fixed to the vertical member. Moreover, when expecting only the function in which an opening reinforcement material supports a sash, each material may be a flat bar.

  The structure of the sash is not particularly limited, and a sash such as an ALC sash, a PC sash, or an RC sash can be selectively used.

  In the present invention, the structure of the blocking member is not particularly limited as long as it can prevent the filler from entering the notch formed in the small edge of the ALC panel and coming into contact with the ALC panel. In other words, the blocking member may be any member that can prevent the filler from coming into contact with the ALC panel even if the filler enters the notch.

  As the blocking member having the above-described function, for example, a member formed by bending a thin metal plate into an L shape can be used. In the case of such a blocking member, when the double-sided tape is applied to one piece constituting the L-shape or an adhesive is applied and the opening is formed, the upright piece faces the notch. It is possible to prevent the filling material from entering the cutout portion by attaching to the lower cross member of the opening reinforcing material at a position corresponding to the cutout portion of the ALC panel.

  In addition, as the blocking member, it is possible to use a member formed by bending two sides of a rectangular metal plate in the same direction as a corner portion of a tray. In the case of such a blocking member, it is possible to prevent the filler from entering the cutout portion by attaching the two raised pieces to the lower cross member of the opening reinforcing member so as to face the cutout portion, Further, even if the filler enters the notch, it can be prevented from coming into contact with the ALC panel.

  As described above, when the blocking member is constituted by a member formed by bending one side into an L shape, or a member formed by bending two sides and forming a corner portion of the tray, the relative position when the ALC panel is locked It is necessary to be able to tolerate general displacement. That is, when the filling material enters the notch, the filled material should not inhibit the relative displacement of the ALC panel.

  Therefore, the blocking member does not simply prevent the filler from coming into contact with the ALC panel, and needs to be able to exhibit a function that can form a gap between the filler and the ALC panel. Become. For this reason, a material such as paper or cloth having no rigidity is not preferable as a material constituting the blocking member having the shape as described above, and it should be a material having a rigidity that is not deformed by the filler. preferable. Examples of such a material include a metal plate and a synthetic resin plate, and any of them can be preferably used.

  Further, the blocking member may be a piece of wood or a synthetic resin foam formed in a rectangular parallelepiped shape corresponding to the shape or size of the opening, or a rubber or metal lump. In particular, since it is reasonable to install the blocking member prior to attaching the draining plate to the opening reinforcing member, the blocking member may be pressed against the lower cross member of the opening reinforcing member by the draining plate. Therefore, the blocking member preferably has elasticity, and is most preferably an elastic body made of a foam having moderate elasticity.

  A method and a part for fixing the blocking member arranged corresponding to the notch formed in the ALC panel are not particularly limited, and are arranged below the lower cross member of the opening reinforcing member or below the lower cross member. It is possible to selectively use the inner surface of a drain plate attached to the lower frame of the sash disposed on the upper surface of the ALC panel and further on the upper surface of the lower cross member.

  The blocking member has at least the same dimension as the lateral dimension of the notch, and is arranged corresponding to the notch formed in the fore edge of the ALC panel. However, in the present invention, the blocking member is not limited to be disposed only in the notch, and may be disposed over the entire length in the lateral direction of the opening. That is, it is essential that the blocking member is disposed corresponding to the notch, but even if it is disposed over other parts, it does not depart from the present invention.

  In the opening configured using the ALC panel, water sealing performance is ensured by arranging a sealing from the outer surface side in the gap formed between the ALC panel and the opening reinforcing material. The backup material is inserted prior to inserting the sealing. For this reason, it is preferable to make the blocking member made of an elastic body exhibit a function as a backup material.

  Next, an embodiment of the opening structure will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view for explaining an opening structure. FIG. 2 is a plan sectional view for explaining the structure of the opening including the notch formed in the edge of the ALC panel. FIG. 3 is a schematic diagram illustrating the structure of a portion including a notch formed in the edge of the ALC panel.

  The opening A according to this embodiment includes a pair of longitudinal members 1a, an opening reinforcing member 1 configured by combining a pair of transverse members composed of an upper transverse member 1b and a lower transverse member 1c, and a longitudinal member of the opening reinforcing member 1. An ALC panel 2 disposed on both sides along 1a and having a protrusion 2a formed along the outer surface at the fore end and a notch 2b formed at a predetermined position, and an ALC panel disposed on the upper side of the upper cross member 1b 3, the ALC panel 4 disposed at the lower part of the lower cross member 1 c, the sash 5 disposed on the opening reinforcing member 1, the draining plate 6 attached to the lower frame 5 b of the sash 5, and the ALC panel 2 And a blocking member 7 arranged corresponding to the notch. And the mortar 8 used as a filler is filled into the gap between the lower cross member 1c of the opening reinforcing member 1 and the lower frame 5b of the sash 5, and the gap formed around the sash frame 5a.

  The opening reinforcing member 1 is connected to a beam in which the upper and lower ends of the vertical member 1a are respectively arranged on the upper and lower sides, and the ALC panel 3 is placed on the upper cross member 1b at the lower end and the upper end at the upper beam. Connected, the ALC panel 4 is placed on a support hardware (not shown) attached to the lower beam at the lower end, and the upper end is connected to the lower cross member 1c. The ALC panel 2 has upper and lower ends connected to upper and lower beams, respectively. Each of the ALC panels 2 to 4 is rotatably connected to the upper and lower beams and the corresponding cross members 1b and 1c using lightning bolt type or Z type hardware not shown.

  As described above, the upper and lower ends of each ALC panel 2 to 4 are respectively connected to the corresponding beams, cross members 1b, 1c so as to be rotatable, so that the upper and lower beams and the cross members 1b, 1c can be connected to each other in the event of an earthquake. When relative horizontal movement occurs between them, it is possible to exert a rocking function that is inclined with this movement.

  A protrusion 2a is formed along the outer surface side of the fore edge of the ALC panel 2, and a sash 5 is disposed on the back side of the protrusion 2a. Therefore, the sash frame 5a of the sash 5 is hidden by the protrusion 2a, and the design property is improved.

  A draining plate 6 is disposed on the sash 5 over the entire length in the width direction, and is attached to the lower frame 5b. For this reason, both end portions in the width direction of the draining plate 6 interfere with the protrusion 2a of the ALC panel 2, and when the draining plate 6 is inserted into the protrusion 2a, avoid the draining plate 6 A notch 2b having a dimension sufficient to ensure a sealing dimension is formed.

  The position of the notch 2b formed in the fore edge of the ALC panel 2 may be a position where the sealing dimension can be ensured by avoiding the draining plate 6. However, in order to ensure the design, it is preferable that the bottom surface 2b1 of the notch 2b is at the same height as the upper end surface of the adjacent ALC panel 4. Thus, since the bottom face 2b1 of the notch 2b and the upper end face of the ALC panel 4 are at the same height, the ceiling 10 can be arranged in a straight line.

  The blocking member 7 is disposed at a position corresponding to the notch 2b formed in the small edge of the ALC panel 2, and the mortar 8 serving as a filler enters the notch 2b by disposing the blocking member 7. In addition, even if it enters the notch 2b, the contact with the ALC panel 2 is prevented.

  In this embodiment, the blocking member 7 is made of a foam obtained by foaming polyethylene at an appropriate magnification, and has a width dimension substantially the same as the lateral dimension of the notch 2b formed in the ALC panel 2, and the notch 2b. The thickness corresponding to the height from the bottom surface 2b1 to the lower surface of the draining plate 6 at the front end 1c1 of the lower cross member 1c of the opening reinforcing member 1 and the length corresponding to the distance from the front end 1c1 to the sealing 10 of the lower cross member 1c. Are formed as a rectangular parallelepiped.

  By forming the blocking member 7 having the shape and dimensions as described above, the blocking member 7 also has a function as a backup material for the sealing 10. Further, a double-sided tape (not shown) is attached to the bottom surface of the blocking member 7, and the double-sided tape is used to attach to the bottom surface 2b1 of the notch portion 2b so as to correspond to the notch portion 2b. ing.

  Accordingly, the space defined by the bottom surface 2b1 and the side surface 2b2 of the cutout portion 2b and the tip portion 1c1 of the lower cross member 1c is substantially free of voids due to the arrangement of the blocking member 7, and the lower cross member 1c and the sash 5 are separated. It becomes possible to prevent the mortar 8 filled in the gap with the lower frame 5b from entering the notch 2b. In particular, the bottom surface 2b1 of the cutout portion 2b and the bottom surface side of the side surface 2b2 are covered with the blocking member 7, and even if the mortar 8 enters the cutout portion 2b, the intruded mortar 8 contacts the ALC panel 2. It is possible to prevent this.

  Further, the notch 2b is filled with the blocking member 7. Since the blocking member 7 has elasticity, the ALC panel 2 should be tilted with the relative horizontal movement of the upper and lower beams during an earthquake. Then, it is elastically deformed with this movement. Therefore, it is possible to ensure the follow-up performance with respect to the deformation of the ALC panel 2, and the locking function is not hindered.

  As described above, the blocking member 7 may be formed of a long foam, and may be disposed over the entire length in the lateral direction along the distal end portion 1c1 of the lower cross member 1c of the opening reinforcing member 1. When the blocking member 7 is disposed, the mortar 8 filled in the gap between the lower frame 5b of the sash 5 and the lower cross member 1c can be blocked from coming into contact with the ALC panels 2 and 4.

  Next, another example of the blocking member will be briefly described. FIG. 4 is a schematic diagram illustrating the cross-sectional shape of the blocking member and the arrangement state with respect to the notch.

  In FIG. 6A, the blocking member 11 having an L-shaped cross section composed of an upright piece 11a and an attachment piece 11b is arranged in correspondence with the notch 2b. The upright piece 11a of the blocking member 11 has a height equal to the distance from the lower cross member 1c to the water draining plate 6 in the notch 2b. And the upright piece 11a is attached by making the attachment piece 11b affix on the lower crosspiece 1c corresponding to the front-end | tip part of the vertical material 1a of the opening reinforcing material 1. FIG.

  FIG. 2B shows the blocking member 12 having a T-shaped cross section arranged in correspondence with the notch 2b. The blocking member 12 is attached in a state where the piece 12b is attached to the draining plate 6 so that the piece 12a corresponds to the tip of the vertical member 1a of the opening reinforcing member 1 and the piece 12b is overlapped on the upper surface of the lower cross member 1c. Yes.

  Any of the blocking members 11 and 12 described above can prevent the filled mortar 8 from entering the notch 2b and contacting the bottom surface 2b1 and the side surface 2b2.

  Next, a procedure for constructing the opening according to the first embodiment will be described. First, the notch 2b is formed in the edge of the ALC panel 2 at the notch processing stage. This notch processing step can be performed at the stage of shipping the ALC panel 2 from the factory, and can also be performed at the construction site.

  Opening reinforcement 1 and ALC panels 2-4 are installed according to the building construction procedure. In the blocking member arrangement stage, prior to attaching the sash frame 5 a to the opening reinforcing member 1, the blocking member 7 is disposed in correspondence with the notch 2 b formed in the fore edge of the ALC panel 2. In this embodiment, the blocking member 7 made of foam is disposed in the notch 2b, and is disposed by being affixed to the bottom surface 2b1 of the notch 2b so as to be pressed against the tip 1c1 of the lower cross member 1c.

  In the draining plate mounting stage, after the blocking member 7 is disposed corresponding to the notch 2b of the ALC panel 2 as described above, the sash frame 5a constituting the sash 5 is mounted on the opening reinforcing member 1. Further, the draining plate 6 is attached to the lower frame 5b of the sash frame 5a.

  In the filling step, the gap formed between the lower cross member 1c of the opening reinforcing member 1 and the lower frame 5b of the sash 5 is filled with mortar 8 serving as a filling material. At this time, the method of filling the mortar 8 is not limited at all, and the filling can be performed using a filling gun. The flow of the mortar 8 filled in the portion corresponding to the notch portion 2b of the ALC panel 2 is restricted by the corner portion constituted by the lower cross member 1c and the vertical member 1a, and the blocking member 7, so that the flow to the notch portion 2b is reduced. Intrusion is prevented and the ALC panel 2 is not touched.

  Before and after the filling step described above, an operation of inserting a backup material into the gap between the ALC panels 2 to 4 and the sash frame 5a of the sash 5 is performed. At this time, since the blocking member 7 is disposed on the bottom surface 2b1 of the notch portion 2b, the blocking member 7 functions as a backup material. Therefore, the backup material is located at a portion other than the portion where the blocking member 7 is disposed. It is constructed. Then, an opening is constructed by constructing the sealing 10 on the outer surface side of the backup material and blocking member 7.

  The opening structure of the present invention is advantageous when used in a building using an ALC panel having a locking function.
