Microfilm of Japanese Utility Model No. 61-62759 (Japanese Utility Model Publication No. 63-28783)

  According to Patent Document 1, it is necessary to tighten the bolts from below to above while maintaining a predetermined positional relationship between the column panel and the left and right vertical frames and the upper frame when the panel is fixed. For this reason, it is necessary to carry out the bolt fixing operation while holding it with one hand so that the transom panel does not fall. Fixing work in an unstable state is dangerous for the operator, and the tightening of the bolt tends to be insufficient, and there is a risk that loosening will occur after construction. In addition, convex brackets are provided on the left and right vertical frames and the upper frame, the lower ends of the brackets are bent inward to form female screw holes, nuts are attached, and the lower end grooves of the panel between panels are used to hide the bolts attached from below. The number of members used in the construction is large, such as covering the wall with a groove closing material.

  Accordingly, the problem to be solved by the present invention is to eliminate such disadvantages of the prior art, and to provide a new transom structure and a construction method thereof that can be constructed safely and easily.

  In order to solve this problem, the present invention according to claim 1 includes a left and right vertical frame and a horizontal frame provided in an opening, and an inter-panel fixed to a space surrounded by the left and right vertical frames and the horizontal frame. It is a strut structure, and a groove extending in the height direction is formed on each side end of the strut panel, and a projecting portion projecting from one surface is provided at the lower end thereof, and the left and right vertical frames are respectively provided with the strut panel. A support member that is formed with a convex portion that fits into the groove of the both-side end and protrudes inward at the predetermined height position, and further protrudes inward at a lower position with a predetermined interval from the fixed space piece. A recess is formed on the lower surface of the horizontal frame to fit the upper end of the interframe panel, and the interspace panel fixing piece is inserted in a state where the protruding portion of the interpan panel is sandwiched between the interspace fixing piece and the support member. Via Le is characterized by comprising fixed.

  The present invention according to claim 2 has a vertical frame member having a convex portion on one side and a fixing piece between the projections projecting at a lower position thereof, a horizontal frame member having a concave portion on one side, and an opening at least at the upper end on both side ends. And a space panel member having a projecting portion projecting to one side at the lower end, and a pair of vertical frame members fixed to the opening with the one side facing the inner surface side. A vertical frame and a horizontal frame member between the upper ends of the left and right vertical frames are fixed to the top of the opening so that the concave forming surface is the lower surface, and a frame is formed as a horizontal frame. Put the panel member and slide it upward with the convex part protruding inward from the left and right vertical frames inserted into the grooves on the both sides of the mouthpiece, and the upper end of the interpanel panel member is the concave part on the lower side of the horizontal frame And the protruding part is After forming a positional relationship in contact with the interspaced fixing piece protruding inward from the frame, in this positional relationship, the support members are attached to the inner surfaces of the left and right vertical frames and the interim panel member is supported from below and temporarily fixed. The inter-panel panel member is fixed to the left and right vertical frames through inter-column fixing pieces to form an inter-panel.

  According to the first aspect of the present invention, since the inter-column structure with a simple configuration is provided with a relatively small number of members, construction is also easy. Since the upper end of the balustrade panel is inserted in the recess formed in the horizontal frame, the upper end of the balustrade panel is adjusted according to the size of the opening (especially the height) and the height of the door installed below at the construction site. Even in the case of excision, the top end of the cut is not exposed, so that the appearance is good, and since no gap is formed between the horizontal frame and the inter-panel, light leakage can be prevented. Further, since the protruding portion of the interpan panel member is fixed in a state of being sandwiched between the intercolumn fixing piece and the support member, a cross structure having excellent strength can be obtained.

  According to the second aspect of the present invention, when the panel is installed, it is slid and moved upward with the convex portions projecting inwardly from the left and right vertical frames inserted into the grooves on the both sides of the panel. However, positioning in the height direction and the thickness direction can be easily performed. In addition, since the interspace panel can be supported from below by the support member in a state where the interpan panel is pulled up to a predetermined height, even if the operator releases his hand from the interpan panel member, the worker holds it at the predetermined height position. Is done. Therefore, it is possible to safely and easily perform the work of fixing the cross panel member by driving a fixing tool such as a screw into the cross fixing piece.

It is a front view which shows the cross structure by one Embodiment of this invention. It is XX sectional drawing in FIG. Front view (a), plan view (b), left side view (c), left side view of modified example (d), and left side view of yet another modified example (e) It is. It is each perspective view which shows embodiment (a) in which the convex part was formed with the dowel, and embodiment (b) in which the convex part was formed with the rod-shaped member about the vertical frame used for this interspace structure. It is each side view which shows embodiment (a) formed with one member, and embodiment (b) formed with two members about the horizontal frame used for this interspace structure. It is a front view which shows the procedure which attaches a cross panel at the time of construction of this cross structure. It is the side view which looked at the state of FIG.6 (b) on the basis of the left vertical frame inner surface.

  The balustrade structure and its construction method according to the present invention will be specifically described below with reference to the accompanying drawings.

  1 and 2 show an inter-column structure 10 according to an embodiment of the present invention, in which an inter-panel 14 is fixed in a space surrounded by left and right vertical frames 11 and 12 and a horizontal frame 13 provided in an opening (not indicated). Has been. In this embodiment, a door 15 is provided below the space panel 14 in the frame space so as to be openable and closable through an operation by a handle 16, more specifically, when viewed from the closed state shown in FIG. 1 and the front of FIG. It can be opened and closed between the open state that opens to the opposite side. Reference numerals 17a and 17b are door stops, which are attached to a pair of door stop grooves 19 (see FIG. 4) formed to extend in the length direction on the inner surfaces of the left and right vertical frames 11 and 12, respectively. The door 15 is in contact with one surface (front of FIG. 1) side of the door 15 near the left and right side mouths, and the door stop 17b is placed on one surface (front of FIG. 1) near the left and right side mouths of the panel 14 described later. Abut. In FIG. 2, reference numeral 34 denotes a pillar, and reference numeral 35 denotes a wall panel stretched on both sides of the pillar 34. The door 15 is pivotally supported between the lower surface of the balustrade panel 14 and the floor surface, or can be opened and closed by a hinge or the like provided on one vertical frame (left vertical frame 11 in the illustrated embodiment). Since the present invention is related to the balustrade structure, the door 15 is not directly related to the subject matter of the present invention, and a further detailed description is omitted. In addition, it is good also as a mere space which can pass without providing the door 15. FIG.

  The left and right vertical frames 11 and 12 are formed from a vertical frame member 18 shown in FIG. The vertical frame member 18 is a long plate-like body having a length dimension substantially the same as the height of the opening and a width dimension substantially the same as the thickness of the opening, and one surface thereof (on the inner side in the construction state). On the surface), a pair of door stop grooves 19 are continuously extended over substantially the entire length. In the door stop groove 19, the leg portion of the door stop 17 a is fitted in the height region of the door 15, and the leg portion of the door stop 17 b is fitted in the height region of the transom panel 14. It can be attached. A convex portion 20 is formed on one side of the door stop groove 19 near the upper end of the side surface of the vertical frame member 18. The convex portion 20 may be an arbitrary number of dowel-shaped convex portions (FIG. 4A) provided at an interval in one or the length direction, or a rod shape extending over a predetermined length. It may be a member (FIG. 4B). In any case, the projecting portion 20 projects inward from the inner surface near the upper ends of the left and right vertical frames 11 and 12 in the constructed interspace structure 10, and is formed in the groove 32 ( (See FIGS. 3 and 7).

  On the side surface of the vertical frame member 18 that is the inner surface side in the construction state, an L-shaped metal fitting 21 is further fixed below the convex portion 20. The L-shaped metal fitting 21 includes a vertical frame fixing piece 21a and a field fixing piece 21b, and any number of fixing holes 21c and 21d are formed in each of the fixing pieces 21a and 21b. And it fixes to the said side surface of the vertical frame member 18 through fixing brackets (not shown), such as a screw, in the fixing hole 21c of the vertical frame fixing piece 21a. By fixing the L-shaped metal fitting 21 in this way, the balustrade fixing piece 21b protrudes inward from the side surface (inner surface) in the construction state (see FIGS. 2, 4, and 6). At this time, the L-shaped metal fitting 21 is located with respect to the vertical frame member 18 so that the interspace fixing piece 21b is in a height position where the interspace fixing piece 21b comes into contact with the upper surface of the protruding portion 22 that protrudes from the lower end of the interspace panel 14 toward one surface. Fixed in place.

  The vertical frame fixing piece 21a is preferably fixed between the pair of door stop grooves 19, and in this way, in a construction state, the vertical frame fixing piece 21a comes into contact with one surface (front side in FIG. 1) near the left and right side mouthpieces. The vertical frame fixing piece 21 a can be concealed by the lower end portion of the door stop 22 attached to the vertical frames 11 and 12. The inter-column fixing piece 21b may be made inconspicuous by being colored in the same color as the inter-panel panel 14, or covered with a resin cover, or the protruding portion 22 of the inter-panel panel 14 in a region where the inter-column fixing piece 21b abuts. 3 is provided with a countersink part 23 (FIG. 3B) having a depth substantially the same as the thickness of the transom fixing piece 21b, and the interstitial fixing part 21b is fitted and accommodated in the countersunk part 23. It can be eliminated.

  A dowel hole 25 into which a dowel 24 can be inserted at a predetermined interval is provided below the L-shaped metal fitting 21 fixed as described above, on the side surface of the vertical frame member 18 that is the inner surface side in the construction state. It is formed (FIG. 4A). The dowel hole 25 is also preferably formed between the pair of door stop grooves 19. In this way, even when the dowel 24 is pulled out and removed after construction, one surface near the left and right side mouths of the door 15 (see FIG. The dowel hole 25 can be concealed by the upper end portion of the door stopper 17a attached to the vertical frames 11 and 12 so as to be in contact with the (1 front) side. In this embodiment, the dowel 24 inserted into the dowel hole 25 constitutes a “support member” that supports the lower panel 14 from below during construction, but the dowel 24 is not limited as long as it performs the same function. For example, a spring-type protrusion that can be buried and protruded in a state of being spring-biased at a predetermined height position on the inner surface of the vertical frame member 18, or a wooden screw that is half-inserted and protruded inward. A thing etc. can also be employ | adopted as a "support member." The distance in the height direction between the interspaced fixing piece 21b of the L-shaped metal fitting 21 fixed to the vertical frame member 18 and the support member such as the dowel 24 inserted into the dowel hole 25 is determined by the protrusion of the interpane panel 14 used. It is substantially the same as the thickness (height) of 22, and the protrusion 22 can be sandwiched between them.

  When a mark serving as a mark is provided in advance on one side surface which is an inner surface in the construction state of the vertical frame member 18 so that the convex portion 20, the L-shaped metal fitting 21 and the support member 24 are provided in the positional relationship described above. good. When a dowel is used as the convex portion 20 and the support member 24, a dowel hole for inserting the dowel serves as a mark.

  In addition, when cutting out the vertical frame member 18 according to the height of the opening part in which the interspace panel 14 and the door 15 are provided, and using it as the vertical frames 11 and 12, care is taken so that the above-mentioned positional relationship is not impaired. . For example, according to the height dimension of the space panel 14 and the door 15, the length may be adjusted by cutting off one or both of the upper and lower sides with respect to the position of the L-shaped bracket 21.

  The horizontal frame 13 is formed from a horizontal frame member 26 shown in FIG. The horizontal frame member 26 has a length dimension substantially the same as the width of the opening, and a concave portion 27 into which the upper end portion of the interpanel 14 is fitted on one surface (surface on the lower surface side in the construction state). It is formed continuously. The horizontal frame member 26 having such a shape may be formed by notching a concave portion 27 on one surface side of a single long plate-like body having a rectangular cross section (FIG. 5A), or The frame member 28 is a long plate-shaped body having a rectangular cross section and the curtain plate member 29 is a long thin plate having an L-shaped cross section, and the upper surface of the fixing piece 29a is fixed to the top of the opening. At the same time, the curtain plate piece 29b may be covered on the upper end surface of the interpanel 14 so that the recess 27 is formed between the fixed piece 29a and the curtain plate piece 29b (FIG. 5B). According to the latter configuration, the processing labor for forming the recess 27 in the single member can be saved, and when the balustrade panel 14 is thick, the curtain plate member 29 is fixed with a gap between the frame member 28. A wide concave portion 27 is provided, and when the column panel 14 is thin, the distal end side of the fixing piece 29a of the curtain plate member 29 can be cut off to make the concave portion 27 narrow, depending on the thickness of the column panel 14 There is an advantage that the width of the recess 27 can be easily adjusted.

  The inter-panel 14 is formed from the inter-panel member 30 shown in FIG. The inter-panel member 30 has a width dimension substantially the same as the opening width (interval between the left and right vertical frames 11, 12) and a thickness dimension substantially the same as the opening thickness (thickness of the left and right vertical frames 11, 12). The panel 31 having a predetermined height dimension is formed in a substantially L shape in a side view formed by providing a protruding portion 22 that protrudes from the lower end to one surface side. The panel 31 may have a flash structure, or may be made of a single plate material. The panel 31 may be produced in the factory as having the above dimensions in advance, but the upper end is cut off at the construction site in accordance with the size of the opening (particularly the height) and the height of the door 15 installed below. It may be used. As described above, the left and right side ends of the panel 31 are provided with the grooves 31 for fittingly accommodating the convex portions 20 provided on the inner surfaces of the left and right vertical frames 11 and 12 so as to be slidable up and down, but the upper end is cut off. In this case, it is necessary to form grooves 32 in the left and right side end of the panel 31 after the cut from the upper end to at least a predetermined length (may continue to the lower end). Further, when the upper end is cut off at the construction site using the panel 31 having the flash structure, a wide panel core material is used in the upper end region so that the upper end is cut out within the range. This is because when the panel 31 having a flash structure is cut out in an area where the core material does not exist, the front and back face materials are not fixed at the upper end of the panel 31 after cutting, and undulation occurs due to humidity. This is because there is a risk of peeling off.

  The protruding portion 22 protrudes to one surface such that the lower surface is flush with the entire lower width of the panel 31, and the protruding length of the protruding portion 32 protruding from the lower surface of the panel 31 is the vertical frame 11. , 12 is equal to or larger than the width dimension of the inter-column fixing piece 21b of the L-shaped metal fitting 21 fixed to the inner surface of the L-shaped metal fitting 21, and as described above, the inter-column fixing piece 21b is fitted to the left and right ends of the upper surface. A counterbore 23 having a length and a depth sufficient to be accommodated is formed.

  As a method for forming the protrusion 22, for example, an embodiment in which the lower end of the panel 31 is cut out from one side, and a rectangular cross-section rod-shaped member 33 a having substantially the same length as the width of the panel 31 is housed in the cutout and fixed. In addition to (FIG. 3C), a rectangular cross-section rod-shaped member 33 b having a length dimension substantially the same as the width of the panel 31 and a width dimension larger than the thickness of the panel 31 is provided on the one surface side of the panel 31. An embodiment (FIG. 3 (d)) that is fixed so as to protrude only on the bottom, or an embodiment (FIG. 3) in which a rectangular cross-section bar member 33c having the same length as the width of the panel 31 is fixed to the lower surface of the panel 31. (E)) can be employed. According to these embodiments, the load of the transom panel 14 is received by the rod-shaped members 33a to 33c via the L-shaped metal fitting 21 in the construction state, and the durability of the panel 31 itself can be improved. In addition, the rod-like member is not only visually seen like a central duck from the side (front side in FIG. 1) from which the rod-like members 33a to 33c protrude in the construction state (see FIG. 1), but also on the opposite side to the panel 31 and the rod-like shape. When the joint surface (line) with the member appears, it will be visually observed from the opposite side as if there is a middle duck. Therefore, according to the embodiment of FIG. 3 (d), when viewed from either the front or back side, it is visually observed that the middle duck is formed, while the implementation of FIG. 3 (c) and FIG. 3 (e) is performed. In the case of the form, it is visually observed as if the middle duck is formed only when viewed from the protruding side of the rod-shaped member. Conventionally, when constructing a field with a middle headquarters, a frame surrounded by left and right vertical frames, horizontal frames and a central headquarters after the left and right vertical and horizontal frames are framed in the opening In the embodiment shown in FIG. 3, the transom panel member 30 having the projecting portion 22 is attached to the vertical frames 11 and 12 in advance. Only by fixing to the fixed L-shaped metal fitting 21, at least on the protruding side, the protruding portion 22 is visually observed as if it is a middle duck, and the rod-shaped members 33 a to 33 c for forming the protruding portion 22 are attached. Depending on the embodiment, it is possible not to make the Nakagamoi visible from the opposite side, and it is easy to configure the space with the Nakagamoi, and it is possible to change the design properties on the front and back Kill

  Next, the construction method of the inter-column structure 10 will be further described with reference to FIG. The vertical frame member 18 (FIG. 4) is attached to the opening so that the door stop groove 19, the convex portion 20, the L-shaped metal fitting 21 and the dowel hole 25 face the inner surface to form the left and right vertical frames 11 and 12. A horizontal frame member 26 (FIG. 5) is attached between the upper ends of the vertical frames 11 and 12 on the top surface of the opening so that the concave portion 27 opens downward, and the frame is configured as the horizontal frame 13. Then, the interpane panel 14 is attached by inserting and fixing the interpanel panel member 30 (FIG. 3) inside the frame. More specifically, first, the transom panel member 30 is placed in a state in which the protruding portion 22 faces forward, and the upper end of the protruding panel 20 is a protruding portion 20 (a protruding portion 20 consisting of a plurality of dowels as shown in FIG. 4A). If it is, it is fitted in the frame so that it is at a slightly lower height than the convex portion 20 so as not to interfere with the dowels at the lowest position. Then, the side panel member 30 in the width (opening width) of the vertical frames 11 and 12 is brought into contact with the side surface of the inter-frame fixing piece 21b of the L-shaped bracket 21 by the side surface of the inter-panel member 30 (the front side surface in FIG. 1). The projections 20 projecting inwardly from the vertical frames 11 and 12 and the grooves 32 formed in the left and right side end of the column panel member 30 are aligned in the vertical direction. With the positional relationship maintained, the projection panel 20 is inserted into the groove 32 by pulling the column panel member 30 upward in the frame so that the column panel member 30 is slid upward in this fitted state. (FIG. 6A).

  When the inter-panel member 30 is slid upward in this way, the upper end is finally fitted and accommodated in the recess 27 on the lower surface of the horizontal frame 13 and the seat formed on the upper surface of the projecting portion 22. In the digging portion 23, the inter-column fixing piece 21b of the L-shaped metal fitting 21 protruding from the inner surfaces of the vertical frame members 11 and 12 is fitted and accommodated. At this time, the dowel holes 24 formed below the interspace fixing pieces 21b on the inner surfaces of the vertical frames 11 and 12 are exposed immediately below the projecting portions 22 of the interspace panel member 30. By inserting 25, it is possible to support the interspace panel member 30 from below and prevent it from falling, and the operator releases the interspace panel member 30 and opens the interspaced fixing piece 21b of the L-shaped bracket 21. A screw 21f, which is a fixing tool, is driven into the mounting hole 21d from above to fix the panel member 30. As a result, the panel 14 is attached.

  The dowel 25 may be removed after the attachment of the interpanel 14 is completed in this way, or may be left attached as it is. According to the latter, the projecting portion 22 of the inter-panel member 30 is fixed in a state of being sandwiched between the inter-field fixing piece 21b of the L-shaped bracket 21 and the dowel 25, so that the inter-structure is excellent in strength. There is an advantage that 10 is obtained. In the former case, since the dowel hole 24 is exposed after the dowel 25 is removed, it is preferably concealed by a concealing member such as a seal. Similarly, when a wood screw is used as the “supporting means” instead of the dowel 25, it is preferable that the screw hole exposed after removing the wood screw is concealed by a concealing member such as a seal. When a spring-type protrusion is used as the “supporting means”, it is preferable that the protrusion is buried and similarly concealed with a concealing member such as a seal. Or you may make it conceal these dowel holes, a screw hole, a spring type protrusion, etc. by the upper end part of the door stop 17a attached to the door stop groove 19 under the L-shaped metal fitting 21. FIG.

  Next, the door stop 17 b is attached to the door stop groove 19 formed on the inner surfaces of the vertical frames 11 and 12. In this embodiment, a pair of leg portions 17a and 17b made of synthetic resin or the like formed in a substantially U-shaped cross section are fitted into and fixed to the pair of door groove 19 respectively. The vertical frame fixing piece 21a of the L-shaped metal fitting 21 can be concealed by attaching the door stopper 17b having a length extending from the upper ends of the L-shaped metal fittings 21 to the upper surface of the space fixing piece 21b of the L-shaped metal fitting 21 in this manner. it can.

  In addition, the convex part 20 and the L-shaped metal fitting 21 may be attached to the vertical frame member 18 in advance at the factory, or may be attached to the vertical frame member 18 before construction as the vertical frames 11 and 12 at the construction site. good. Further, when the column panel 14 is not attached immediately after the vertical frames 11 and 12 and the horizontal frame 13 are attached to the opening, the projection 20 and the L-shaped bracket 21 are fixed from the inner surface of the vertical frames 11 and 12 in this state. If the piece 21b protrudes, it may be possible that an object collides with the piece 21b and damages the object, the convex portion 20 or the L-shaped bracket 21. Therefore, after the vertical frames 11 and 12 are attached, You may attach the convex part 20 and the L-shaped metal fitting 21 with respect to the vertical frames 11 and 12 just before construction.

  As described above, the door 15 is not directly related to the subject of the present invention, and therefore the description of the construction method is omitted.
