[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a remodeling sash lower frame that is installed on top of an existing sash lower frame in a state where it is left as it is, and a remodeling method using a so-called cover method using the remodeling sash lower frame.
[0002]
BACKGROUND OF THE INVENTION
In recent years, “barrier-free,” which eliminates the steps that prevent the elderly and small children from stumbling or hindering passage in wheelchairs, has been widely used in medical and welfare facilities, public facilities, educational facilities, and in apartments. Has also been required as a specification.
[0003]
By the way, such a demand for “barrier-free” is being demanded not only for indoors, but also for doorways of a frame that separates the room from the outside, such as a sash lower frame that separates a balcony from a room. In response to this request, sash lower frames satisfying the specifications are gradually being used for new facilities and condominium buildings, but it is difficult to achieve this for existing buildings.
[0004]
As a remodeling method for attaching a new sash lower frame to an existing building, a cover method is known in which a renovated sash lower frame is attached on top of an existing sash lower frame while leaving it. This cover method is simpler than the removal method in which the existing sash lower frame is completely removed and then a new sash lower frame is attached, and the risk of damaging the outer walls, etc., is reduced, and the cost is relatively low. It is excellent in that it can be done with. However, in the conventional cover construction method, first, a connecting member for connecting the existing sash lower frame and the renovated sash lower frame is mounted on the existing sash lower frame, and the renovated sash lower frame is fixed thereon. As a result, the remodeled sash lower frame itself looks like a hurdle between the floor of the balcony and the floor of the room in a convex shape, so it is impossible to pass in a wheelchair with this. It was impossible. In addition, in the case where a table plate higher than the floor in the room is formed adjacent to the existing sash lower frame, the upper end of the renovated sash lower frame is interposed in a convex shape one step higher than the upper surface of the table. Thus, when viewed from the floor in the room, two steps are generated in the height direction. In this case, of course, it is impossible to pass through a wheelchair, but for example, when the elderly or small children try to go out of the room to the balcony, the lifted feet are caught on the remodeled sash lower frame protruding from the upper surface of the tabletop It was dangerous that they could trip over and fall down into the lower balcony.
[0005]
[Problems to be solved by the invention]
The present invention has been made based on such a background, and an object of the present invention is to eliminate the need for the above-described coupling member and to make the mounting member substantially flush with the floor surface or the upper surface of the dining table in the installed state. An object of the present invention is to provide a remodeling sash lower frame and a remodeling method using the remodeling sash lower frame. Another object of the present invention is to provide a refurbishment method for realizing barrier-free by making the floor of a room or the upper surface of a table board, the upper end of a remodeling sash lower frame, and the floor of a balcony flush.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides a rail that receives a door of a shoji that is interposed at the entrance of a frame that separates the inside and outside of a room from the upper surface of the indoor floor surface or a top plate at a position one step higher than the floor surface. Also, for the refurbished sash lower frame that is mounted on the existing sash lower frame in a lower position, the upper end of the projecting element including the rail that receives the door of the shoji is formed at a predetermined substantially the same height as the upper plate portion. , The Extends downward from the upper plate and is directly screwed to the rail of the existing sash lower frame And a fixing piece integrally formed on the upper plate and an auxiliary fixing piece that supplements the length of the fixing piece separately from the upper plate. Fixed leg portion, and the fixed leg portion is directly screwed to the rail of the existing sash lower frame, and the upper end of the projecting element of the upper plate portion is in contact with the indoor floor surface or the upper surface of the dining table. At approximately the same height What I did It is characterized by.
[0007]
In this remodeled sash lower frame, the upper end of the projecting element of the upper plate portion is formed at a predetermined substantially the same height. . For this reason Remodeling sash lower frame itself is flat Is barrier-free . And, on this upper plate part, the fixed leg part which is screwed directly to the rail of the existing sash lower frame is formed. You. For this reason Traditional In the cover method Like the remodeled sash lower frame , The connecting member interposed in the height direction Unnecessary In the mounted state, the projecting height of the remodeled sash lower frame can be reduced, and the opening dimension in the height direction of the remodeled sash frame itself can be made larger than the conventional remodeled sash lower frame. Further, the fixing leg has a fixing piece integrally formed on the upper plate and an auxiliary fixing piece which supplements the length of the fixing piece separately from the upper plate. Therefore, by changing the length of the fixed leg portion along the height direction with the auxiliary fixing piece, it can be adapted to various existing sash lower frames whose sizes and shapes are not uniform according to the manufacturer and specifications. . Furthermore, the upper end of the projecting element of the upper plate part is With the fixed legs directly screwed to the rails of the existing sash lower frame, at the same height level as the indoor floor or the top of the table board Becomes . Therefore, it is possible to make the upper end of the projecting element of the renovated sash lower frame flush with the indoor floor surface. In this case, it is possible to realize barrier-free remodeling sash lower frame with respect to the indoor floor surface. it can. It is also possible to make the upper end of the protruding element of the renovated sash lower frame flush with the upper surface of the table board, which is one step higher than the indoor floor, in this case, instead of using the conventional renovated sash lower frame. Also, the step on the indoor floor can be reduced by one step.
[0008]
The projecting elements of the upper plate portion of the lower frame of the remodeled sash may not only have a case in which all upper ends have the same height, but also have a step in a range in which it is considered that there is no obstacle to a wheelchair. Regarding the height of the upper plate including the projecting elements and the fixed leg, the fixed leg is also attached to the rail of the existing sash lower frame. Screw directly Not only when the upper end of the projecting element of the upper plate part is completely flat with the indoor floor surface or the upper surface of the table board, but also in a range that does not hinder the passage in a wheelchair. And a step may occur between them. Regarding the height of these steps, it cannot be said unconditionally because there are differences in the physique of wheelchair users and differences in the type of wheelchair, whether manual or electric, but if it is in the range of about 20 mm, it is generally possible to use a wheelchair. It is considered passable.
[0010]
Regarding the remodeled sash lower frame, a water passage hole is formed at an outdoor position of the rail formed on the room side of the upper plate portion in order to enhance water tightness, and a lower side of the water passage hole is formed. A hollow drainage receiving chamber can be formed inside.
[0011]
According to the remodeled sash lower frame, since the water passage hole is formed to penetrate at the outdoor side position of the sliding door receiving rail of the sliding door formed closer to the room of the upper plate portion, the rainwater accumulated around the rail is provided. Can be reliably drained without infiltrating into the room side. Therefore, even if the renovated sash lower frame and the indoor floor surface or the renovated sash lower frame and the upper surface of the table board are flush with each other, it is possible to prevent rainwater from entering the indoor side by the renovated sash lower frame. .
[0012]
Regarding the above-mentioned remodeled sash lower frame in which the water passage hole and the drainage receiving chamber are formed, a drainage port for discharging the rainwater accumulated inside is drained to the bottom wall and side walls defining the drainage receiving chamber. And a drain pipe can be connected to this drain port.
[0013]
According to the remodeled sash lower frame, rainwater can be drained from the remodeled sash lower frame (drainage receiving room) through the drain port and drain pipe, so that rainwater does not accumulate in the drainage receiving room and high watertightness is exhibited. can do. Even when the drainage pipe is not connected, for example, a drainage hole may be formed in the side wall or the bottom wall on the balcony side of the drainage receiving room, and rainwater may be drained from the drainage hole to the existing balcony as it is. .
[0014]
Further, with respect to the remodeled sash lower frame in which the water passage hole and the drainage receiving chamber are formed, the upper plate portion is provided with a glazing formed through the water passage hole communicating with the drainage receiving chamber so as to be detachable. Is also good.
[0015]
According to the remodeled sash lower frame, since the glazing can be attached to and detached from the upper plate portion, the work of removing the glazing and removing soil and the like accumulated in the drainage receiving chamber can be easily performed. By attaching a mesh material covering the water holes to the backside of the glazing, it is possible to prevent relatively large debris such as fallen leaves from entering the drainage receiving chamber. The wastewater treatment will not be disturbed.
[0016]
Further, the remodeled sash lower frame having the water hole and the drainage receiving chamber is provided with an intermediate partition that divides the drainage receiving chamber into two, and the intermediate partition connects the two divided chambers. The through hole may be formed so as to be positioned at a location different from a location where the drain pipe is connected to the drain receiving chamber in the longitudinal direction of the sash lower frame.
[0017]
According to the remodeled sash lower frame, even when rainwater flows backward from the drainpipe to the drainage receiving chamber, such as when cleaning the inside of the drainpipe, the rainwater that has flown back once contacts the intermediate partition. Since the momentum is buffered, it is possible to prevent water from being blown up from the water passage hole and flooded into the room from the lower frame of the remodeled sash.
[0018]
The present invention also provides the following remodeling method using the above-described remodeling sash lower frame of the present invention to achieve the above object. That is, the present invention provides an upper plate portion in which a rail for receiving a sliding door of a shoji interposed at an entrance and exit that separates the inside and outside of a room is lower than the upper surface of the indoor floor surface or a top plate located at a position higher than the floor surface. However, the remodeling method of attaching any of the above-described remodeled sash lower frames to the existing sash lower frame at a position higher than the floor surface of the existing balcony, wherein the remodeled sash lower frame is stacked on the existing sash lower frame. Fix and install the renovated floor material on the existing balcony so that the floor is at the same height as the upper end of the protruding element of the remodeling sash lower frame, and The upper end of the projecting element of the lower frame of the refurbished sash and the floor surface of the renovated floor material are formed to be substantially flat.
[0019]
According to this refurbishment method, since the upper surface of the indoor floor surface or the top plate, the upper end of the projecting element of the renovation sash lower frame, and the renovation floor material are substantially flat, for example, even in a wheelchair, it is easy to use a balcony. You can go out and use the balcony as if it were a living room or part of a room.
[0020]
When the floor surface of the room or the upper surface of the dining table, the upper end of the projecting element of the lower frame of the renovated sash, and the floor surface of the renovated floor material, which are realized by such a renovation method, become “substantially flat”. This means that not only is completely flat, but also that there is a step in a range that does not hinder the passage in a wheelchair. It should be noted that the height of the step cannot be unconditionally determined because there are differences in the physique and the like of a wheelchair user and differences in the type of a wheelchair such as manual or electric, but if it is in a range of about 20 mm, It is considered that there is no obstacle to wheelchair traffic.
[0021]
Further, in the case where the remodeling sash lower frame in which the water passage hole and the drainage receiving chamber are formed by the above-described remodeling method is used, drainage treatment of rainwater accumulated in the drainage receiving chamber can be performed by various methods. As an example, in the remodeling method of the present invention, a drainage port for draining rainwater accumulated in the drainage receiving chamber is provided on a wall defining a drainage receiving chamber of the lower frame of the remodeling sash, and the floor surface of the existing balcony is provided through the drainage port. It is designed to drain rainwater into the area. In this case, the drainage may be drained directly to the floor of the existing balcony.However, if the waterproof mortar is to be filled around the lower frame of the renovated sash to increase watertightness, the existing drainage outlet may be used. It is preferable to attach a drain pipe of a length leading to the floor of the balcony.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a remodeling sash lower frame according to the present invention and a remodeling method using the same will be described with reference to the drawings. In the following embodiment, a refurbished sash frame for a sliding door is exemplified, but it is also possible to configure a refurbished sash frame for a single sliding door.
[0023]
First Embodiment First, as a first embodiment, a description will be given of a remodeling example in which a step is removed from a floor in a room to a balcony based on a remodeling sash lower frame and a remodeling method of the present invention.
[0024]
[Description of refurbished sash frame 1]
[0025]
As shown in FIG. 1, the refurbished sash frame 1 is composed of a refurbished lower frame 2, a pair of refurbished vertical frames 3, and a refurbished upper frame 4, and pulls the outdoor sliding door So and the indoor sliding door Si in the drawing direction x. It can be opened and closed by turning over each other. As will be described later, the remodeling lower frame 2, the remodeling vertical frame 3, and the remodeling upper frame 4 constituting the remodeling sash frame 1 are put on the existing lower frame 12, the existing vertical frame 13, and the existing upper frame 14, respectively, of the existing sash frames. To be attached.
[0026]
Description of remodeling lower frame 2 The remodeling lower frame 2 is formed into a cross-sectional shape as shown in FIGS. 2 and 3 by extrusion of an aluminum material. On the upper plate portion 21, an edge wall 21 a as a “projecting element” from the outdoor side to the indoor side, a rail 21 b for receiving a door roller of a screen door (not shown), and two rails 21 c for receiving a door roller of Shoji So, Si. And an upright wall 21d are protruded, and their upper ends have a predetermined same height.
[0027]
The edge wall 21a is a portion indicating that it is the outdoor end of the lower frame 2 for refurbishment. The standing wall 21d on the opposite side mainly has a function of providing the interior of the remodeling lower frame 2 with watertightness and airtightness. That is, a mounting portion 21e projecting in a U-shaped cross section is formed on the outdoor side surface of the standing wall 21d, and a rubber airtight material 21f mounted on the mounting portion 21e is mounted on the indoor side with respect to the lower frame of the sliding door Si on the indoor side. It is a factor that gives water tightness and air tightness to the room. In addition, a concave portion for receiving dew water is formed on the indoor side of the standing wall 21d.
[0028]
A glazing 22 having a U-shaped cross section is attached between the rails 21c of the sliding doors So and Si. The glazing 22 is attached to the remodeling lower frame 2 by engaging a pair of downwardly extending engagement legs 22 a (see FIG. 3) with engagement grooves 23 a of a drainage receiving chamber 23 formed below the upper plate 21. You can easily do it just by letting it do. A plurality of oblong water holes 22b are formed through the glazing 22 so that rainwater accumulated between the rails 21c and 21c can be drained into the drainage receiving chamber 23 to improve the water discharge.
[0029]
On the upper surface of the glazing 22, an upright wall portion 22c as a "projecting element" is formed at a position closer to the indoor side than the water passage hole 22b, and the side surface thereof has a U-shaped cross section. A portion 22d is formed. An airtight material 22e that elastically presses against the lower frame of the outdoor sliding door So from the indoor side is held in the mounting portion 22d so as to be able to be inserted and removed by sliding. Therefore, when the airtight material 22e is in contact with the lower frame of the sliding door So on the outdoor side, rainwater does not enter under the sliding door Si on the indoor side. In addition, since the glazing 22 can be removed from the lower frame 2 for refitting, when replacing the airtight material 22e, the glazing 22 is removed from the lower frame 2 for remodeling, and the airtight material 22e is slid from the mounting recess 22c to be pulled out. The replacement work can be performed easily by sliding the airtight material 22e into the mounting recess 22c.
[0030]
The glazing 22 is provided with a stainless net member 22f that covers the water passage hole 22b on the back surface side. The mesh of the net member 22f has a size that does not impair the water permeability of the water passage hole 22b and that a relatively large trash such as fallen leaves, which hinders the drainage treatment in the drainage receiving chamber 23, does not enter. In this example, the net size is about 1.5 to 2 mm square.
[0031]
Two glazings 22 configured as described above are attached to the remodeling lower frame 2, and the length of one of the glazings 22 is slightly longer than half the length of the remodeling lower frame 2. The length of one is slightly shorter than half. Then, when cleaning the inside of the remodeling lower frame 2, for example, as shown in FIG. 3, the short glazing 22 is lifted and removed from the remodeling lower frame 2 to clean the exposed interior. Next, the long glazing 22 is slid to the position where the short glazing 22 was located to remove dust and the like from the exposed interior. Although not shown, the short glazing 22 is removed and the glazing 22 is cleaned while the sliding doors Si and So are both closed, and then the long glazing 22 is slid to the place where the short glazing 22 was located. The lower side that has been located may be cleaned. In this way, the inside of the glazing 22 and the drainage receiving chamber 23 can be easily cleaned.
[0032]
An upper receiving chamber 23c and a lower receiving chamber 23d are formed in a drain receiving chamber 23 below the upper plate 21 by an intermediate partition 23b that divides a hollow internal space into upper and lower parts. A through hole 23e is formed in the intermediate partition 23b, and the rainwater flowing into the upper receiving chamber 23c flows into the lower receiving chamber 23d through the through hole 23e. Then, the water is drained from the drain port 23g of the bottom wall 23f along the drain pipe P to the floor surface Bf1 of the existing balcony. Although not shown in FIG. 2, a net material smaller than the net material 22f is attached so as to cover the through hole 23e so that sand and dust smaller than the net material 22f do not flow into the lower receiving chamber 23d. You may.
[0033]
In FIG. 2, for convenience of description, the formation position of the through hole 23 e and the opening position of the drain port 23 g for connecting the drain pipe P formed in the bottom wall 23 f of the lower receiving chamber 23 d are determined by the length of the remodeled lower frame 2. Although shown as the same positional relationship in the direction, the opening position of the through hole 23e and the drain port 23g is actually a different positional relationship in the longitudinal direction of the remodeling lower frame 2. Therefore, even if the rainwater flowing backward from the drain pipe P flows into the lower receiving chamber 23d vigorously, the momentum of the rainwater spouting from the drain port 23g is buffered by the intermediate partition 23b. There is no inconvenience that rainwater spouts vigorously onto the upper plate portion 21 from the through hole 23e.
[0034]
On the bottom wall 23f of the drainage receiving chamber 23, a fixing piece 23h which is hung downward is formed. A screw hole is formed in the fixing piece 23h, and the fixing piece 23h is fixed to the outdoor rail 12b protruding from the upper plate portion 12a of the existing lower frame 12 with a screw N. The fixed piece 23h and the wall defining the drainage receiving chamber 23 constitute a "fixed leg". The length along the height direction of the fixing piece 23h and the drainage receiving chamber 23 is such that the fixing piece 23h is fixed to the rail 12b of the existing lower frame 12 as the "projecting element" of the remodeling lower frame 2. The upper ends of the edge wall 21a, the rails 21b and 21c, the upright wall 21d, and the upright wall portion 22d are formed in such a size as to be at substantially the same height position as the indoor floor surface Rf. Therefore, "barrier-free" of the remodeling lower frame 2 with respect to the indoor floor surface Rf is realized.
[0035]
In addition, an inverted L-shaped support member 24 is provided on the back surface of the indoor side end of the upper plate portion 21, and the horizontal plate portion 24 a is fixed to the upper plate portion 21 with screws, and the vertical plate portion is formed. Reference numeral 24b is screw-fixed to the floor in the room, and supports a load acting on the upper plate portion 21. In this example, the support member 24 is provided separately from the remodeling lower frame 2. The reason for this is that the inclination of the upper plate portion 12 a of the existing sash lower frame to be remodeled with respect to the horizontal direction varies widely, This is because if the support member is integrally formed with the remodeling sash lower frame with the length, the portion corresponding to the vertical plate portion may be too long to be attached.
[0036]
Description of renovated vertical frame 3 A pair of left and right vertical frames 3 are integrally connected by an door molding 33 to an outer frame 31 facing the outside and an inner frame 32 facing the room as shown in FIG. It is formed as an overall shape.
[0037]
The outer frame portion 31 is formed with a mounting step portion 31a of a waterproof sealing material Se at a tip end of the crank shape. A fixing piece 31b protruding toward the room is formed on the inner side surface of the outer frame portion 31. A mounting bracket 5 (see FIG. 5) for fixing the retrofitted vertical frame 3 to the existing vertical frame 13 is provided here. Is to be fixed to. Similarly, a fixing flange 32a is also formed on the inner frame portion 32 toward the outside of the room, and the mounting bracket 5 is fixed.
[0038]
Explanation of remodeling upper frame 4 As shown in FIG. 2, the upper frame 4 is formed by integrally connecting an outer frame portion 41 facing the outside and an inner frame portion 42 facing the room by a top plate portion 43 by extrusion molding of an aluminum material. It is formed as a shape.
[0039]
At the upper end side of the outer frame portion 41, a mounting step portion 41a of a sealing material Se having a crank shape is formed toward a room. A fixing piece 41 b protruding toward the room is formed underneath, and a mounting bracket 5 for fixing the renovated upper frame 4 to the existing upper frame 14 is fixed here. Similarly, a fixing flange 42a is formed on the upper end of the inner frame portion 42 toward the outside, so that the mounting bracket 5 is fixed.
[0040]
[Description of mounting bracket 5]
[0041]
Here, the mounting bracket 5 for fixing the vertical frame 3 and the upper frame 4 of the remodeled sash frame 1 to the vertical frame 13 and the upper frame 14 of the existing sash frame will be described. As shown in FIG. 5, the mounting bracket 5 combines two substantially U-shaped metal fittings 51 and 52 with the back plates 51a and 52a facing each other and inserted into the bolt holes of the back plates 51a and 52a. A bolt 53 is fixed by a nut 54. The metal fittings 51, 52 are formed with pressing flanges 51b, 52b and groove-shaped engaging portions 51c, 52c. The pressing flanges 51b and 52b are provided with pressing pads 51d and 52d made of an elastic and non-slip material.
[0042]
The pressing flange 51b of the metal fitting 51 presses the inner frame portions 13a and 14a of the vertical frame 13 and the upper frame 14 of the existing sash frame from the inside via the pressing pad 51d from the inside, and the engaging portion 51c has The fixing flanges 32a, 42a formed on the vertical frame 3 of the remodeling sash frame 1 and the inner frame portions 32, 42 of the upper frame 4 are inserted.
[0043]
The pressing flange 52b of the metal fitting 52 presses the vertical frame 13 of the existing sash frame and the outer frame portions 13b and 14b of the upper frame 14 from the inside through the pressing pad 52d from the inside, and the engaging portion 52c has The fixing pieces 31b and 41b formed on the outer frame portions 31 and 41 of the vertical frame 3 and the upper frame 4 of the refurbished sash frame 1 are inserted.
[0044]
Then, in order to attach the vertical frame 3 of the refurbished sash frame 1 to the vertical frame 13 of the existing sash frame using the metal fittings 51 and 52, the bolts 53 are tightened from the state shown in FIG. As shown in b), the metal fittings 51 and 52 are relatively separated from each other. Then, the pressing flanges 51b and 52b press the inner frame portion 13a and the outer frame portion 13b of the vertical frame 13 from inside. On the other hand, the fixing flange 32a of the inner frame portion 32 of the vertical frame 3 is inserted into the engaging portion 51c, and the fixing piece 31b of the outer frame portion 31 of the vertical frame 3 is inserted into the engaging portion 52c. In this way, the renovated vertical frame 3 is firmly fixed to the existing vertical frame 13 by the mounting bracket 5. The remodeled upper frame 4 is also firmly fixed to the existing upper frame 14 via the mounting bracket 5 in the same manner.
[0045]
[Explanation of renovation method]
[0046]
