Description

  The present invention relates to a connection structure and a joining method of a vertical frame material and a horizontal frame material constituting an entrance / exit frame of an entrance / exit frame installed at an entrance / exit in a house.

  When a door opening or other wall opening is provided in the house, an entrance / exit frame (also referred to as an opening frame, a joinery frame, or a three-way frame) is attached so as to surround the inner periphery of the wall opening. The entrance / exit frame is formed in a rectangular shape by a pair of left and right vertical frame members and a horizontal frame member (kamoi) that connects the upper ends thereof. The joint between the vertical frame material and the horizontal frame material is a form in which the vertical frame material wins over the horizontal frame material (the end face of the horizontal frame material abuts the side surface of the vertical frame material), or the vertical frame material and the horizontal frame material. In many cases, the ends of the frame members are joined together in any form that is cut and fastened at 45 degrees. Even when joining in any form, the joint should be securely joined in advance using screws, insert nuts, dowels, or other fixtures, and the entrance / exit frame assembled in this way inside the wall opening. In general, the vertical frame material and the horizontal frame material are fixed to the wall base material or the like from the base side by screws.

In the construction of such an entrance / exit frame, a joint structure disclosed in Patent Documents 1-3 and the like is known as a technique for beautifully and accurately fitting the joint between the vertical frame member and the horizontal frame member.
Japanese Utility Model Publication No. 6-8684 JP-A-8-326435

  When the wall opening is provided up to the full height of the ceiling, it hinders the implementation of the construction method in which the entrance frame is pre-assembled into a gate shape and then built into the wall opening. This is because there is not enough space in the height direction, and when the entrance / exit frame is erected, the corners and the like collide with the ceiling surface.

  In this case, a post-assembly method is employed in which the vertical frame member and the horizontal frame member are separately attached to the wall base material without first assembling the entrance / exit frame. However, in this post-assembly method, a gap or a gap is likely to occur at the abutting portion between the vertical frame member and the horizontal frame member that are attached separately. Therefore, even in the post-assembly method, it is necessary to bring the material ends of the vertical frame material and the horizontal frame material together and securely join them. However, since the joining operation must be performed from the inside of the frame, it is difficult to prevent the screws and other fixtures from being exposed to the finished surface inside the frame. In addition, it is difficult to do complicated work because it is a high-altitude work with full ceiling height.

  For this reason, in the construction method in which the vertical frame material and horizontal frame material are assembled later, there is a need for a joint structure that allows both frame materials to be joined easily and accurately and provides a beautifully finished design. It is done. However, the joint structure disclosed in Patent Document 1 is designed to absorb construction errors between the vertical frame material and the horizontal frame material, but is not capable of firmly joining both frame materials. . Further, the corner member disclosed in Patent Document 2 has a problem that it is exposed to the finished surface and impairs the design.

  The present invention has been made to solve the above-described problems, and can be suitably implemented in a method of assembling a vertical frame material and a horizontal frame material, and the vertical frame material and the horizontal frame material. The joint structure of the entrance / exit frame that can join the joint with the joint firmly and beautifully, and the joining method of the entrance / exit frame using the joint structure are proposed.

  In order to achieve the above-described object, the entrance / exit frame joint structure of the present invention has a joint between the vertical frame member (41) and the lateral frame member (42) constituting the entrance / exit frame (4). 42) is a joint structure in which the vertical frame member (41) is joined in a form that prevails against the vertical frame member (41), and the projection (22) having a cross-sectional shape and the groove (33) slide in one direction to each other. Of the joining members formed of a pair of the male member (2) and the female member (3) formed so as to be fitted, either one protrudes from the inner surface of the upper end portion of the vertical frame member (41). Of the vertical frame member (41) which is attached and is mounted in a digging portion (43) formed so as to open to the end surface and the upper surface of the horizontal frame member (42). The end face of the horizontal frame member (42) is brought into contact with the inner side surface, and the horizontal frame member (42) is slid upward from below the fixed position to There vertical frame members (41) transverse frame member and (42), characterized in that it is joined fitted to each other.

  According to this joint structure, the material ends of the vertical frame member (41) and the horizontal frame member (42) are attracted to each other through the joining member formed of a pair of the male member (2) and the female member (3). The joints of both frame members are joined with high accuracy by fitting the convex portion (22) having a dovetail cross section and the concave groove (33).

  In the fitting structure of the above-mentioned entrance / exit frame, the male member (2) constituting the joining member has a dovetail-shaped convex portion (22) projecting substantially at the front center of the back plate portion (21), and a female member ( 3) shall have a pair of female engaging piece (32, 32) which protrudes from both sides of the front surface of the back plate (31) and forms a dovetail groove (33).

  Furthermore, a hollow part (23) may be formed along the central axis (20) of the convex part (22) in the male member (2), and a screw hole (26) may be formed in the hollow part (23). A recess (34) may be formed at the bottom of the recess (33) in the female member (3), and a screw hole (36) may be formed in the recess (34). According to such a structure, each back board part (21, 31) of a male member (2) and a female member (3) is made with respect to the predetermined position of a vertical frame material (41) or a horizontal frame material (42). The screw can be easily fixed, and it is also possible to prevent the screw from interfering with the fitting surface having a cross-sectional dove shape. It is practical that the male member (2) and the female member (3) are resin molded products. The screw holes (26, 36) may be long holes in order to allow fine adjustment of the mounting position.

  Furthermore, the convex part (22) of the male member (2) in the said joining member and the taper along a sliding direction may be formed in the ditch | groove (33) of a female member (3). According to this structure, fitting operation with a male member (2) and a female member (3) becomes easy.

  Moreover, the joining method of the entrance / exit frame of this invention WHEREIN: The joint of the vertical frame material (41) and horizontal frame material (42) which comprises the entrance / exit frame (4) is made into a vertical frame with respect to a horizontal frame material (42). The material (41) is a joining method for joining in a winning form, and is formed so that the convex part (22) having a cross-sectional dove shape and the concave groove (33) can be fitted to each other while sliding in one direction. In addition, one of the joining members consisting of a pair of the male member (2) and the female member (3) is attached in advance to protrude from the inner surface of the upper end portion of the vertical frame member (41), and the other is attached, It is attached in the notch part (43) formed so as to open to the end face and the upper surface of the horizontal frame member (42) in advance, and after fixing the vertical frame member (41) to both side edges of the wall opening part, The end portion of the horizontal frame member (42) is brought into contact with the inner surface of the vertical frame member (41) and is lifted upward from below a fixed position to thereby join the joint portion. Between the fitted together, wherein the joining vertical frame members (41) transverse frame member and (42) with.

  In this joining method, the vertical frame member (41) is fixed to the wall opening portion first, the end surface of the horizontal frame member (42) is applied to the inner side surface thereof, and the horizontal frame member (41) is lifted upward. 42) is joined to the vertical frame member (41), the joining work is simple, and it is easy to carry out even at a high ceiling height. Also, a beautiful finish can be obtained without exposing screws or other fixtures on the inner surface of the frame.

  According to the joint structure and joining method of the entrance / exit frame of the present invention configured as described above, the end portions of the vertical frame member and the horizontal frame member through the joining member composed of a pair of a male member and a female member. They are attracted to each other and joined together with no gaps or misalignment, and a beautiful and strong joint with no exposure of fixtures or the like is obtained.

  Since the work of attaching the joining member to the vertical frame material / horizontal frame material can be performed in advance in the processing process of the factory, it is easy to ensure the processing quality and the preliminary assembly check can be performed in advance.

  In addition, according to the present invention, the entrance / exit frame joint structure and joining method are applied to the inner surface of the built-in vertical frame member by applying the end face of the horizontal frame member and lifting it upward, thereby converting the horizontal frame member into the vertical frame member. Since they are joined, work at high places is easy.

  Moreover, the fitting structure and joining method of the entrance / exit frame of this invention are convenient for fixing an entrance / exit frame with respect to a wall base material from the frame inner side. Therefore, it can be easily applied not only to the “front attachment method” in which the inner wall board is finished after fixing the entrance / exit frame to the wall base material, but also to the “retrofitting method” in which the entrance / exit frame is attached after finishing the inner wall board or cloth.

  Embodiments of the present invention will be described below. First, the detailed structure of the joining member used for the joint structure and joining method of the entrance / exit frame of this invention is demonstrated, referring FIGS.

  The joining member is constituted by a pair of a male member 2 shown in FIGS. 1 and 2 and a female member 3 shown in FIGS. Both the male member 2 and the female member 3 are formed of a synthetic resin material having appropriate rigidity and lubricity.

  The male member 2 has a substantially flat plate-like back plate portion 21 and a convex portion 22 protruding from the front surface of the back plate portion 21. The size of the back plate portion 21 is about 25 ± 5 mm in length and width, and the thickness is about 3 ± 1 mm.

  The convex portion 22 is substantially equal in width from one side (upper side) to the opposite side (lower side) of the back plate portion 21 along the symmetrical central axis 20 that is a sliding direction when the male member 2 is fitted to the female member 3. It protrudes at. However, strictly speaking, the convex portion is such that the side that becomes the front end (lower side in the illustrated form) when fitted to the female member 3 is slightly thinner than the side that becomes the rear end (the same upper side). A slight taper is given to the 22 front shape. The cross section of the convex portion 22 in the direction orthogonal to the symmetrical central axis 20 has a so-called ant shape in which the front end side is wider than the base end side. The projecting dimension from the front surface of the back plate portion 21 is about 5 to 6 mm.

  A recess 23 having a substantially groove-shaped cross section is formed in the central portion of the protrusion 22 along the symmetry central axis 20. Since the convex portion 22 is divided into two portions by the concave portion 23, each side portion facing each other across the concave portion 23 is referred to as a male engaging piece 24. That is, the convex portion 22 is constituted by a pair of male engaging pieces 24 and 24.

  A screw hole 26 for fixing the male member 2 to the entrance / exit frame 4 or the like is formed in the recess portion 23 so as to penetrate the back plate portion 21. In the illustrated embodiment, the screw holes 26 are formed at two locations along the symmetrical central axis 20, and one of them is a long hole extending in a direction orthogonal to the symmetrical central axis 20.

  In addition, the male member 2 in the illustrated form is processed into a shape in which both corners on the side (lower side) that becomes the tip when fitted with the female member 3 are rounded.

  The female member 3 includes a substantially flat plate-like back plate portion 31 and a pair of female engaging pieces 32 and 32 protruding from both front side portions of the back plate portion 31. The size of the back plate portion 31 is substantially the same as that of the male member 2 and about 25 ± 5 mm in length and width, and the thickness is about 7 ± 1 mm which is slightly thicker than the male member 2.

  The pair of female engaging pieces 32, 32 are opposed to each other with a symmetrical central axis 30 serving as a sliding direction when the male member 2 is fitted to the female member 3. And the convex part 22 (male engagement piece 24, 24) of the said male member 2 is fitted in the ditch | groove 33 formed between both the female engagement pieces 32 and 32. FIG. Therefore, the depth of the concave groove 33 (projection dimension of the female engagement piece 32 from the back plate portion 31) substantially matches the projection dimension of the convex portion 22 of the male member 2. Further, the width of the concave groove 33 (opposite distance between the female engaging pieces 32) is adjusted to the taper applied to the convex portion 22 of the male member 2, and becomes the inlet side when fitting with the male member 2 (illustrated). In this form, the upper side is slightly wider than the back side (same, lower side). The cross section of the concave groove 33 in the direction orthogonal to the symmetric central axis 30 has a dovetail shape whose front end side is narrower than the groove bottom side in accordance with the cross sectional shape of the convex portion 22 of the male member 2.

  A recessed portion 34 having a substantially groove-shaped cross section is formed in the central portion of the recessed groove 33 along the symmetrical central axis 30. Since the recess 34 is formed by digging the back plate portion 31 with a width slightly narrower than the groove width of the concave groove 33, the thickness of the back plate portion 31 is 3 ± 1 mm at that location. It is about.

  A screw hole 36 for fixing the female member 3 to the entrance / exit frame 4 or the like is formed in the recess 34 so as to penetrate the back plate 31. In the illustrated embodiment, the screw hole 36 is formed at one central portion, but a plurality of screw holes 36 may be formed in the same manner as the male member 2, or the screw hole 36 may be a long hole. .

  In addition, the female member 3 in the illustrated form is processed into a shape in which both corners on the back side (lower side) when fitted to the male member 2 are rounded.

  FIG. 5 is an explanatory diagram for illustrating a fitting structure and joining method of an entry / exit frame using the joining member, wherein (a) in the upper left is a guide diagram showing the entry position of the entry / exit frame, and (b). FIG. 4 is an enlarged perspective view showing a method for joining the joints. FIG. 6 is a top view of the joint structure, and FIG. 7 is a longitudinal sectional view of the joint structure. The entrance / exit frame 4 includes a pair of left and right vertical frame members 41 and 41 and a horizontal frame member 42 that connects the upper ends thereof.

  In the illustrated embodiment, the two male members 2 and 2 are attached to the inner side surface at the upper end portion of the vertical frame member 41 with an appropriate interval in the horizontal direction. The male member 2 is screw-fixed to the inner side surface of the vertical frame member 41 with the top side facing the upper end surface of the vertical frame member 41 with the top side facing downward when fitted to the female member 3. Therefore, when viewed from outside the entrance / exit frame 4, the male member 2 protrudes from the inner surface of the vertical frame member 41.

  On the other hand, two end portions 43 and 43 are formed at both ends of the horizontal frame member 42 in accordance with the position of the male member 2 attached to the vertical frame member 41, and the female member 3 is placed in each recess portion 43. It is attached. Each digging portion 43 is open over the end surface and the upper surface of the horizontal frame member 42, and the depth of the digging portion 43 as viewed from the end side of the horizontal frame material 42 allows the male member 2 and the female member 3 to be fitted. It matches the thickness of the joined member in the state. Further, the height and width of the digging portion 43 match the height and width of the joining member. The two female members 3 are both arranged in the digging portion 43 with the side that becomes the entrance facing the male member 2 facing upward, the top surface aligned with the upper surface of the horizontal frame member 42, and the digging portion 43. It is fixed to the back side of the screw. The reason why the corners of the male member 2 and the female member 3 are rounded is that the corners are rounded when the digging portion 43 for storing them is cut by a router. is there.

  These joining members are preferably fixed in advance at predetermined positions of the vertical frame member 41 and the horizontal frame member 42 in a wood processing factory or the like. However, the vertical frame member 41 can be easily cut into a predetermined length at the construction site and attached to the joining member.

  The construction of the entrance / exit frame 4 at the site starts by installing the vertical frame members 41 and 41 on both side edges of the wall opening. The fixing means for the vertical frame member 41 to the wall base material 5 is not particularly limited. However, in the “retrofitting method” in which the entrance / exit frame 4 is attached after finishing the inner wall board or cloth, the vertical frame member 41 cannot be constructed from the base side. Is fixed to the wall base material 5 from the inner side of the frame using nails, screws, dedicated metal fittings, or the like. By installing the vertical frame member 41, the male member 2 forming one of the joining members is disposed in the upper corner of the wall opening.

  Next, the horizontal frame member 42 is inserted between the vertical frame members 41 facing each other. Engraved portions 43, 43 are formed on the end surface of the horizontal frame member 42, and the female members 3, 3 are attached therein, but the female member 3 does not protrude from the end surface of the horizontal frame member 42. The horizontal frame member 42 can be inserted and sandwiched between the vertical frame members 41 and 41.

  The horizontal frame member 42 is lifted up to the upper side of the wall opening in a state where the end surface of the horizontal frame member 42 is in contact with the inner side surface of the vertical frame member 41. Then, the female member 3 attached to both ends of the horizontal frame member 42 receives the convex portion 22 (a pair of male engaging pieces 24, 24) of the male member 2 in the concave groove 33. 2 is mated. The male member 2 fitted integrally with the female member 3 is accommodated in the digging portion 43. Thus, the abutting portion between the horizontal frame member 42 and the vertical frame member 41 is drawn without a gap, and in this state, the horizontal frame member 42 is nail-fixed to the wall base material 5 (or the ceiling base material).

  When the vertical frame member 41 and the horizontal frame member 42 are fixed at predetermined positions, a door stop (not shown) or the like is attached to the inside of both the frame members 41 and 42. The nail for fixing both the frame members 41 and 42 to the wall base material 5 is hidden by the door stop.

  By such a work procedure, the entrance / exit frame 4 in the joining form in which the vertical frame member 41 wins over the horizontal frame member 42 can be constructed with high accuracy. This operation can be carried out with a small burden from the inside of the frame, even with the entrance / exit frame 4 having a full ceiling height. Moreover, since the joining member is not exposed to the finished surface inside the frame, the finished appearance is excellent.

  In addition, as other embodiment of this invention, the positional relationship of the male member 2 and the female member 3 which comprises a joining member can also be replaced. In this case, the shape of the digging portion 43 formed at the end of the horizontal frame member 42 may be the same as in the above embodiment, but the female member 3 attached to the vertical frame member 41 is at the entrance when mating with the male member 2. The male member 2 attached to the horizontal frame member 42 faces downward, and the side that becomes the tip when fitted to the female member 3 faces upward.

  Further, the detailed shapes of the male member 2 and the female member 3 can be somewhat modified without departing from the gist of the present invention.
