(First embodiment)
An assembly structure of an opening inner frame member of a building according to an embodiment of the present invention will be described. In this embodiment, the window frame which comprises a bay window as an inner frame material of the opening part of a building is mentioned as an example, and is demonstrated. FIG. 1 is a perspective view showing a state in which a window frame is attached to an opening provided on a wall surface of a building, and FIG. 2 is an exploded perspective view showing a state before the window frame is attached.

  As shown in FIG. 1, the window frame 100 is fixed so as to be fitted into an opening provided in the wall surface 200. The window frame includes a flange-shaped opening end peripheral edge 12a along the wall surface 200, and the flange cover 3 is attached to the outer surface frame.

  The window frame 100 has four frame plates 1,..., 1 arranged side by side so as to form a rectangular opening, and the side surfaces of adjacent frame plates 1,. By connecting at 2, it is configured in a frame shape. The corner piece 2 has a corner portion 27 that fills a space generated between adjacent frame plates as a member constituting the opening end portion peripheral edge 12a. The corner portion and the end portion of the flange cover 3 are concealed by the corner cap 4. The corner piece 2 and the corner cap 4 constitute a connecting member 60 together with a seal member 5 described later.

Each frame plate 1 includes a flat plate portion 11 constituting the side wall 11 a of the window frame 100 and a flange portion 12 erected substantially orthogonally from the flat plate portion 11. When the window frame is attached to the wall surface 200, the flange portion 12 is a portion corresponding to the opening edge periphery 12 a of the window frame 100. The window frame 100 is fixed to the wall surface 200 by being fitted into the opening 201 with the flange portion 12 as an indoor side and screwed to the wall surface 200 with, for example, a screw or a nail via the flange portion 12.

  FIG. 3 is an enlarged cross-sectional view showing the vicinity of the flange portion 12 of the frame plate 1 with the flange cover 3 attached. The flange cover 3 includes a flat plate portion 32, a cover piece 33 that is bent substantially perpendicularly in the thickness direction from one end portion in the width direction of the flat plate portion 32, and a substantially vertical shape in the thickness direction from the other end portion of the flat plate portion 32. And a second engaging claw 35 that is formed so as to protrude substantially perpendicularly in the thickness direction from the vicinity of one end in the width direction of the flat plate portion 32. The cover piece 33 is formed so as to cover the second engagement claw 35 from the outside. The outer surface of the flange cover 3 is formed of a weather resistant resin or the like.

  The flange cover 3 is engaged with the frame plate 1 by fitting the two engagement claws 34 and 35 to the respective engagement pieces 13 formed on the flange portion 12 of the frame plate 1.

  The dimension in the width direction of the cover body of the base end side portion of each engagement claw 34, 35 is smaller than the minimum dimension in the width direction of the flange portion 12 of the base end side portion of each engagement piece 13. The rigidity of 34 and 35 is formed so that it may become smaller than the rigidity of each engaging piece 13. FIG. Therefore, when the flange cover 3 is attached to the flange portion 12, the engaging claws 34 and 35 are elastically deformed in the direction close to each other, and then returned to the direction away from each other by the elastic recovery force. The flange cover 3 can be locked and attached. Further, by sliding the flange cover 3 in the longitudinal direction, the engaging claws 34 and 35 and the engaging pieces 13 are engaged, and the flange cover 3 is engaged with the engaging pieces 13 and attached.

FIG. 4 shows a configuration in the vicinity of the outside joint portion of the window frame from the outside of the window frame 100. The corner pieces 2 are arranged so that the side surfaces 1a and 1a of the flat plate portions 11 of the two adjacent frame plates 1 and 1 are arranged in an intersecting direction (for example, an orthogonal direction) so that their one sides are close to each other. It is a member which connects both frame plates 1 and 1 in a fixed state.

  FIG. 5 is a perspective view showing the configuration of the corner piece 2, and FIG. 6 is a front view of the corner piece 2 shown in FIG. FIG. 7 is a plan view of the corner piece 2 shown in FIG. FIG. 8 is a cross-sectional view taken along the line VIII-VIII in FIG. 5 and shows a state in which the frame plate 1 and the seal member are virtually arranged. FIG. 9 is an enlarged view showing a configuration in the vicinity of the corner portion 27 of the corner piece 2.

  The corner piece 2 is made of a general-purpose resin such as polypropylene, and is formed by, for example, injection molding. As shown in FIG. 4, the corner piece 2 includes an abutment support portion 20 for abutting and supporting adjacent frame plates 1 and 1 arranged in a direction crossing each other, and two frame plates 1 and 1. And a corner portion 27 that fills a space formed between the flange portions 12 and 12 adjacent to each other.

  The abutting support portion 20 is a rod-shaped member and has two abutting surfaces 21 and 21 that can abut along the side surfaces 1a and 1a of the frame plates 1 and 1 arranged as shown in FIG. The two contact surfaces 21 are provided so as to be orthogonal to each other. From the respective contact surfaces 21, 21, support walls 23, 23 disposed along the outer surface 1 c of the frame plate 1 disposed on the contact surface are substantially the entire region in the longitudinal direction of the contact support portion 20. And it is erected over the corner portion 27.

  In addition, the support walls 23 and 23 do not necessarily need to be provided continuously over the entire region of the contact support portion 20, and the back side of the frame plate 1 may be provided intermittently at a plurality of locations. Moreover, the support wall provided in the corner part 27 and the support wall provided in the contact | abutting support part 20 do not need to be continuous, and may be provided independently in each location.

  As shown in FIG. 5 and FIG. 8, the contact support portion 20 is configured by a rod-like body having a generally rectangular cross section, and the contact surfaces 21 and 21 are configured by the outer surfaces of adjacent walls. By configuring the abutment support portion 20 to be hollow, the amount of resin material is reduced and the flexibility is improved and the handling is improved and the weight is reduced as compared with the case where the abutment support portion 20 is composed of a solid square member. Can be achieved. In addition, if the contact support part 20 is the structure which has the contact surfaces 21 and 21 extended in the direction orthogonal to each other, the cross-sectional shape will not be ask | required, for example, the cross-section L-shape where an outer surface is used as a contact surface It may be.

  As shown in FIG. 8, the abutting surface 21 is configured such that its width direction dimension is smaller than the thickness dimension W of the frame plate 1. A seal fixing groove 22 is formed between the adjacent contact surfaces 21 and 21 over the entire length of the contact support portion 20. Since the contact surface 21 is configured to be thinner than the thickness dimension of the frame plate, when the frame plate 1 is brought into contact with the contact surface 21, one side 1b of the two frame plates is more than the contact surface 21. Projects inward. Therefore, as shown in FIG. 9, when the frame plate 1 is fixed to the contact surface 21, the seal member insertion region defined by the seal fixing groove 22 and the side surfaces 1 a of the two frame plates 1, 1 is It is formed.

The positions of the two contact surfaces are configured such that a slight gap is formed between one side 1b of the frame plate fixed so as to face each other. The gap is preferably 5 mm or less, and is usually about 0.5 to 2 mm. If the gap is too narrow, it takes time to insert the seal member 5, and the insertion portion of the seal member may be easily damaged. On the other hand, in the case of a wide gap exceeding 5 mm, since the sealing member 5 described later is configured to be wide, the appearance is deteriorated, and the assembly work of the frame material becomes difficult.

  Further, as shown in FIGS. 7 and 8, the contact surface 21 of the contact support portion 20 may be formed with a sealing recess 21 a at the center. The seal member 21b can be disposed inside the seal recess 21a, and in addition to the seal member 5 inserted into the seal member insertion region, double waterproofing is performed, so that the seal member 21b can be more reliably removed from the joint portion. Leakage can be prevented.

  Further, the contact support portion 20 is provided with a screw hole 25 which is an example of a fixing member insertion through hole extending in a direction orthogonal to the contact surface 21. The screws 30 are screwed into the side surfaces 1a and 1a of the two frame plates 1 and 1 through the screw holes 25, so that the corner piece 2 and both the frame plates 1 and 1 are fixed as shown in FIG. . At this time, since the screw hole 25 extends in a direction perpendicular to the contact surface 21, the screw 30 is inserted perpendicularly to the side surfaces 1 a and 1 a of the both frame plates 1 and 1. This prevents the screw 30 from being inserted obliquely with respect to the side surface 1a and the tip of the screw 30 popping out from the surfaces of the two frame plates 1, 1, thereby further reducing the thickness of the frame plates 1, 1. It becomes possible.

  The corner portion 27 connected to one end portion of the abutting support portion 20 is a plate-like member having substantially the same thickness as the flange portion 12, and has a thin central portion (see FIG. 4). A fitting hole 29 for fixing the corner cap 4 is provided in the main surface of the corner portion 27 so as to penetrate the corner portion 27. The thin portion of the corner portion 27 functions as a space in which the insertion piece 41 of the corner cap 4 is stored when the corner cap 4 described later is attached.

  As shown in FIGS. 5, 6 and 9, the corner portion 27 is provided with second support walls 28, 28 so as to face the support wall 23. The flange portion 12 of the frame plate 1 is clamped by the portion 23a installed on the corner portion 27 of the support wall 23 and the second support wall 28, and positioning with respect to the corner piece 2 can be easily and reliably performed.

  The seal member 5 is made of, for example, silicon rubber. As shown in FIGS. 8 and 9, the seal member 5 is inserted into the cover portion 51 covering the joint portion and the seal fixing groove 22 to be fixed to the joint portion. The unit 52 is configured. The seal member 5 inserts the insertion portion 52 into the seal fixing groove 22 of the abutting support portion 20 from the gap formed between the sides 1b of the frame plate when the construction is performed on the joint portion (see FIG. 9). Thereby, the coating | coated part 51 will be arrange | positioned and fixed to the joint part of each frame board, and the sealing member 5 and the frame board 1 will be fixed firmly.

  10A and 10B are diagrams showing the configuration of the corner cap, where FIG. 10A is a plan view, FIG. 10B is a left side view, and FIG. 10C is a rear view. The corner cap 4 is a member attached to the corner portion 27 of the corner piece 2, and the appearance of the finish can be improved by covering and concealing the corner portion 27. As shown in FIG. 9, an insertion piece 41 is provided on the inner side surface 40 a of the main body portion 40 of the corner cap 4, and the corner cap is fixed to the corner portion 27 by being inserted into the fitting hole 29 in the corner portion. To do. The insertion piece 41 is provided with a barb at the tip, and is configured so that the corner cap 4 does not easily fall off from the corner portion 27. Moreover, since the center part of the corner part 27 is provided thinly as mentioned above, a clearance gap is formed between the wall surfaces 200, and the insertion piece 41 is accommodated in the clearance gap.

  Further, the corner cap 4 includes a side wall 43 that covers the outside of the flange portion and the corner portion 27 around the body portion 40 that covers the corner portion. Further, a flange covering portion 44 that covers the end portion of the flange cover 3 is provided on the side where the side wall of the main body portion 40 is not provided, and conceals the boundary portion between the flange cover 3 and the corner portion. Furthermore, the joint contact part 42 is provided in the part contact | abutted to a joint, and the edge part of the sealing member 5 is coat | covered.

  Next, the procedure for assembling the inner frame material of this embodiment will be described. First, the side surface 1a of the frame plate 1 is brought into contact with the contact surface 21 of the corner piece 2, and the side wall of the flange portion 12 of the frame plate 1 is disposed between the support wall 23 and the second support wall 28 for alignment. Do. Another frame plate 1 is arranged in the same manner. As a result, the two frame plates 1 and 1 are temporarily fixed by the corner piece 2 in such a state that the two side plates 1a and 1a face each other in the crossing direction so that the sides of the side plates 1a and 1a are close to each other. At this time, a sealing member may be applied in the sealing recess 21 a of the contact surface 21, and a sealing material may be disposed between the side surface 1 a of the frame plate 1 and the contact surface 21. By disposing the sealing material, water leakage between the side surface of the frame plate 1 and the contact surface 21 can be prevented.

  Next, a screw 30 is inserted into the screw hole 25 to fix the corner piece 2 and both the frame plates 1 and 1. Thereby, as shown in FIG. 3, the corner piece 2 connects both the frame plates 1 and 1. It should be noted that the side holes 1a and 1a of the frame plates 1 and 1 may or may not be provided with holes for inserting the screws 30 in advance. If the insertion hole is not provided in advance, the frame plate 1 has a foaming ratio of 1.1 to 5.0 times (for example, 1) in order to facilitate tightening of the screws 30 to the frame plate 1. .5 times) is preferably composed of a low-foam extruded member. As the material of the frame plate 1, a thermoplastic synthetic resin, for example, vinyl chloride resin, ABS resin (acrylonitrile-butadiene-styrene copolymer) or the like can be used. Moreover, the thickness dimension W of the frame board 1 is about 5-12 mm normally.

  Next, the window frame is fixed to the wall surface 200 using screws or the like from the surface side of the flange portion 12, and then the flange cover 3 is attached to the surface of the flange portion 12 (see FIG. 9). The flange cover 3 is cut as necessary so as to be substantially equal to the length dimension of the flange portion 12 of the frame plate.

FIG. 16 is a cross-sectional view showing the configuration of the seal member in the present embodiment. The sealing member 5 has a flat covering portion 51 that covers the joint portion, and includes two insertion portions 52a and 52b. In the case of using a wet seal together with the sealant 55, as shown in FIG. 17, the hooking portions of the insertion portions 52a and 52b are held by the sealant 55, so that the seal member 5 is removed from the seal fixing groove 22. It becomes difficult to come off and is particularly preferable.

  In this embodiment, the work of attaching the corner cap 4 is first. After the locking claw 46 is inserted into the locking claw insertion space 39 and locked to the engagement corner portion 38, the corner cap 5 is pressed so as to be in close contact with the corner portion 27, and the engagement protrusion 45 of the side wall 43 is pressed. The first fitting groove 36 is fitted.

  By attaching the corner cap as described above, the seal member pressing portion 47 formed on the inner surface of the joint covering portion 42 is strongly pressed against the covering portion 51, and the covering portion 51 is pressed toward the joint side. Thereby, the coating | coated part 51 deform | transforms and it is in the state which closely_contact | adhered to the flat plate part 11, and the two insertion parts 52 open, and the sealing member 5 and the frame board 1 are fixed firmly.

  Since the end portion of the seal member 5 easily falls off from the seal fixing groove 22, the end portion is pressed by the seal member pressing portion 47 and is engaged more firmly by deformation of the insertion portion 52. 5 can be prevented from falling off.

  The corner piece and the corner cap of the present embodiment can be reliably engaged with each other by using the first and second locking portions provided on the side surface of the corner portion. Moreover, since no through hole is provided in the corner portion 27, water does not leak from the hole.

  In addition, this invention is not limited to said each embodiment, It can implement in another various aspect. For example, in the above embodiment, the rectangular window frame 100 is configured by the four frame plates 1,..., 1, but the present invention is not limited to this. For example, a polygonal window frame such as a triangle or a pentagon may be configured by two or more frame plates 1,. In this case, the polygonal window frame can be configured by changing the angle formed by the two contact surfaces 21 of the corner piece 2.

  The assembly structure of an opening inner frame material of a building according to the present invention is useful as an inner frame material of an opening portion such as a bay window or an entrance of a building.
