  Before continuing the description of the present invention, the same parts are denoted by the same reference numerals in the accompanying drawings. The best mode for carrying out the present invention will be described below with reference to the drawings.

  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 the wall surface 200. The window frame is provided with a flange-shaped opening end peripheral edge 12a in a shape along the wall surface 200, and the cover member 3 is appropriately attached to the outer frame 12a.

  As shown in FIG. 2, the window frame 100 has four side plates 1,..., 1 arranged side by side so as to form a rectangular opening, and the side surfaces of adjacent side plates 1,. Are connected by four connecting members 2,..., 2 to form a frame shape. FIG. 2 shows the window frame in a state where the cover member 3 is not provided. Each side plate 1 includes a side plate main body portion 11 constituting the side wall 11 a of the window frame 100 and a flange portion 12 erected substantially orthogonally from the side plate main body 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 a partially enlarged perspective view showing a state in which the connecting member 2 is attached to the side surfaces of two adjacent side plates 1 and 1. FIG. 3 shows a configuration in the vicinity of the outer corner portion of the window frame from the outside of the window frame 100. The connecting member 2 is arranged in a state in which the side surfaces 1a and 1a of two adjacent side plates 1 and 1 are arranged in a crossing direction (for example, an orthogonal direction) so that one side is close to each other and fixed so as to face each other. This is a member for connecting the side plates 1 and 1 together. The connecting member 2 and the side plate 1 are fixed by driving a screw 30 or a nail into a screw hole 25 provided in the connecting member 2.

  4 is a perspective view showing the configuration of the connecting member 2, and FIG. 5 is a front view of the connecting member 2 shown in FIG. 6 is a plan view of the connecting member 2 shown in FIG. FIG. 7 is an enlarged view showing a configuration in the vicinity of the corner connecting portion 27 of the connecting member 2. FIG. 8 is a sectional view taken along line VIII-VIII in FIG. 4 and shows a state in which the side plate 1 and the seal member are virtually arranged.

  The connecting member 2 is made of a resin material such as polypropylene, and is formed by, for example, injection molding. When the two side plates 1 and 1 are arranged as shown in FIG. 3, the connecting member 2 includes a corner connecting portion 27 that fills a space formed between adjacent flange portions 12 and 12 and forms a corner portion. And a connecting member main body 20 for contacting and supporting adjacent side plates 1 and 1 arranged in a direction intersecting each other. The connecting member main body portion 20 is provided in the vicinity of the corner portion of the corner connecting portion 27, and the extending direction thereof is configured to be substantially perpendicular to the main surface 27 a of the corner connecting portion 27. Yes.

  The connecting member main body 20 is a rod-like member and has two contact surfaces 21 and 21 that can contact along the side surfaces 1a and 1a of the side 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 that support the side plate 1 disposed along the outer surface 1 c of the side plate 1 disposed on the contact surface are the length of the connecting member main body 20. It is erected over almost the entire area. Further, the support walls 23 and 23 are provided so as to extend to the corner connecting portion 27.

  In addition, the support walls 23 and 23 do not necessarily need to be provided continuously over the whole area | region of the connection member main-body part 20, and the back side of the side plate 1 may be provided in multiple places intermittently. Moreover, the support wall provided in the corner connection part 27 and the support wall provided in the connection member main-body part 20 do not need to be continuous, and may be comprised as another member.

  As shown in FIGS. 4 and 8, the connecting member main body 20 is formed of a rod having a generally rectangular cross section, and the contact surfaces 21 and 21 are formed by the outer surfaces of adjacent walls. By configuring the connecting member main body portion 20 to be hollow, it is possible to reduce the amount of the resin material and improve flexibility and handleability as compared to configuring the connecting member main body portion 20 from a faithful square. . The connecting member main body 20 may have any cross-sectional shape as long as the connecting member main body 20 has contact surfaces 21 and 21 extending in a direction perpendicular to each other. For example, the connecting member main body 20 may have an L-shaped cross section.

  The abutting surface 21 is configured such that its width direction dimension is smaller than the thickness dimension W of the side plate 1. Thus, since the contact surface is configured to be thinner than the thickness dimension of the side plate, when the side plate 1 is brought into contact with the contact surface 21, one side 1b of the two side plates is more than the contact surface 21. Projects inward. The positions of the two contact surfaces are configured such that a slight gap is formed between one side 1b of the side plate fixed so as to face each other. The slight gap is preferably 5 mm or less, and is usually about 0.5 to 2 mm. If the gap is too narrow, such as less than 0.1 mm, the seal member may be insufficiently inserted. In addition, in the case of a wide gap exceeding 5 mm, it is difficult to assemble the frame material.

  A seal fixing groove 22 is provided between the adjacent contact surfaces 21 and 21 over the entire length of the connecting member main body 20. Therefore, as shown in FIG. 8, when the side plate 1 is fixed to the contact surface 21, a seal member insertion region defined by the seal fixing groove 22 and the side surface 1 a of the two side plates 1, 1 is formed. The

  Moreover, as shown in FIG.7 and FIG.8, as for the contact surface 21 of the connection member main-body part 20, the recessed part 21a for a seal | sticker may be formed in the center part so that the periphery may become high with respect to a center part. . By disposing the sealing material inside the sealing recess 21a, water leakage between the contact surface 21 and the side surface 1a of the side plate 1 can be prevented. Moreover, in addition to the sealing member inserted into the sealing member insertion region, water leakage from the corner portion can be more reliably prevented by performing double waterproofing treatment.

  The connecting member main body 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 screw 30 is screwed into the side surfaces 1a and 1a of the two side plates 1 and 1 through the screw holes 25, whereby the connecting member 2 and the side plates 1 and 1 are fixed as shown in FIG. At this time, since the screw hole 25 extends in a direction orthogonal to the contact surfaces 21a and 21b, the screw 30 is inserted perpendicularly to the side surfaces 1a and 1a of the side plates 1 and 1, respectively. This prevents the problem that the screw 30 is inserted obliquely with respect to the side surface 1a and the tip of the screw 30 protrudes from the surface of the side plates 1 and 1, so that the thickness of the side plates 1 and 1 can be further reduced. It becomes possible.

  As shown in FIGS. 5 and 7, the corner connecting portion 27 connected to one end of the connecting member main body portion 20 is secondly opposed to the portion 23 a installed on the corner connecting portion 27 of the support wall 23. Support walls 28 are provided. The flange portion 12 of the side plate 1 is clamped by the portion 23a installed on the corner connecting portion 27 of the support wall 23 and the second support wall 28, so that the positioning burden on the connecting member 2 can be reduced and the side plate is assembled at the time of assembly. 1 can be temporarily fixed to improve the ease of assembly.

  Moreover, the cover member attachment groove | channel 24 is provided in the main surface 27a of the corner connection part 27, and the attachment of the cover member 3 after assembling a connection member and a side plate can be strengthened so that it may mention later. . That is, the cover member fixing groove 24 is provided on the peripheral edge 26 of the cover member mounting groove 24 and the peripheral edge 27b of the corner connecting portion 27 facing the peripheral edge 26 in the X-axis direction in the figure, so that the cover member 3 can be fixed.

  Further, the corner connecting portion 27 is provided with a cover member abutting wall 29, which can be used as a positioning reference when the cover member is attached, as will be described later. Further, the inner edge 29a of the cover member abutting wall 29 is configured to protrude slightly from the inner edge of the cover member 3, as shown in FIG. 9B. For this reason, as will be described later, after the two cover members are attached, a gap 33 (see FIG. 9C) having a size corresponding to the protrusion amount A is formed in the cover member 3. By embedding a sealing material in the gap 33, water leakage between the cover members 3 and 3 can be prevented.

  Next, a method for assembling the connecting member 2 and the side plate 1 will be described.

  First, the contact surface 21 of the connecting member 2 contacts the side surface 1a of the side plate 1 and the flange portion 12 of the side plate 1 is sandwiched between the support wall 23 and the second support wall 28 for alignment. Similarly, the other side plate is similarly arranged. As a result, the two side plates 1 and 1 are temporarily fixed by the connecting member 2 in a state where the side plates 1 and 1 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 side plate 1 and the contact surface 21. By disposing the sealing material, water leakage between the side surface of the side plate 1 and the contact surface 21 can be prevented.

  Next, the screws 30 are inserted into the side surfaces 1a and 1a of the side plates 1 and 1 through the screw holes 25, and the connecting member 2 and the side plates 1 and 1 are fixed. Thereby, as shown in FIG. 3, the connection member 2 connects the both side plates 1 and 1. At this time, the side holes 1a and 1a of the side plates 1 and 1 may or may not be provided with holes for inserting the screws 30 in advance. When the insertion hole is not provided in advance, the side plate 1 has an expansion ratio of 1.1 to 5.0 times (for example, 1.5 times) in order to facilitate tightening of the screw 30 to the side plate 1. It is preferable that it is composed of a low-foam extruded member. As a material of the side plate 1, a thermoplastic synthetic resin such as vinyl chloride resin, ABS resin (acrylonitrile-butadiene-styrene copolymer) can be used. Further, the thickness dimension W of the side plate 1 is usually about 5 to 12 mm.

  In addition, the window frame 100 according to the present embodiment includes four connecting portions 2 of four abutting portions of side surfaces 1a,..., 1a formed by arranging the four side plates 1,. , ..., 2 can be created by connecting.

  Thereafter, the assembled window frame is fixed to the wall surface 200, and the seal member 30 is applied to the inner corner portion of the window frame, which is a portion fixed so as to abut the side surfaces of two adjacent side plates. The seal member is made of, for example, high-viscosity silicon, and solidifies with time after application. As shown in FIG. 9A, the seal member 30 passes through a gap of about 1 mm between one side 1b of the side plate fixed so as to abut at the time of application to the corner portion, and the seal fixing of the connecting member main body portion 20 is performed. It is applied so as to enter the groove 22 for use. Thereby, the sealing member 30 is located not only on the surface of each side plate but also on the side surface side of the side plate 1, and the fixing strength between the sealing member 30 and the side plate 1 can be increased. Further, since the seal member in the seal fixing groove 22 is not exposed on the surface, it does not peel off when an external force such as cleaning is applied, and the exposed portion deteriorates with time. Even if the peeling occurs, it remains in the seal fixing groove 22. Accordingly, water leakage from the corner can be prevented.

  Then, the cover member 3 is attached to the opening edge part periphery 12a of the assembled window frame. FIG. 9B is a diagram illustrating a state in which the cover member is attached to only one flange portion. In FIG. 9B, the seal member 30 is not shown in order to clarify the positional relationship between the side plate 1 and the cover member. The cover member 3 is attached so as to cover the surfaces of the flange portion and the corner connecting portion 27, and the cover member attaching peripheral edge 13 a of the flange portion and the peripheral edge 26 of the cover member attaching groove 24 of the corner connecting portion 27 and the corner connecting portion. 27 is configured to be engaged with the outer peripheral edge 27b of the 27. After the cover member 3 is pressed and locked against the opening edge peripheral edge 12a of the window frame, the cover member is slid as indicated by an arrow 40 until the edge 3a hits the cover member abutting wall 29.

  Next, the other cover member 3 is attached. The cover member is attached so as to cover the flange portion 12. As described above, the inner edge 29a of the cover member abutting wall 29 is configured to protrude slightly from the inner edge of the cover member 3 as shown in FIG. 9B. A gap 33 is formed between the two cover members. A sealing material is applied to the gap 33 to prevent water leakage between the cover members.

  As mentioned above, according to the assembly structure of the frame part in the opening part of the building concerning embodiment of this invention, when the side plate 1 which comprises the side wall of the window frame 100 is provided in the connection member 2, the side surface 1a of the side plate 1 and the seal fixing Since the space defined by the groove 22 is formed, when the seal member is applied to the inner corner portion of the side plate 1, the region seal member enters. Therefore, the coating strength of the seal member can be increased, and the problem of water leakage caused by shrinkage or peeling of the seal member over time can be prevented.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, in the above embodiment, the rectangular window frame 100 is configured by the four side 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 side 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 connecting member 2.

  Since the assembly structure and the connecting member of the opening inner frame material of the building according to the present invention can increase the strength of the seal member formed between the two side plates, the inner frame of the opening such as the bay window or entrance of the building Useful as a material.
