Description

  The present invention relates to a member connector used when two members are joined in a wooden building.

A wooden building is constructed by connecting a number of members such as columns and beams in a grid pattern. And, at places where important members such as columns and beams are connected, it is necessary to secure sufficient strength using various metal fittings or the like so as to withstand various external forces such as earthquakes. In addition, it is necessary to ensure a certain level of strength even in a joint portion where the acting load is relatively small so as not to be inadvertently damaged. For this reason, various methods such as bolts and nails are selected for connecting members in addition to the traditional combination of hozo and hozo groove, including the method of interposing various modern metal fittings. In addition to the following documents, many patent applications have been filed for metal fittings.
JP 2002-302999 A

  In recent years, the preference for wooden buildings has diversified, and there is a demand for buildings that make the structure of pillars, beams, and other structures deliberately visible from the inside of the room, creating an atmosphere similar to an old house. In this case, if the metal fittings and bolts for joining members are exposed, the precious atmosphere will be destroyed, so the metal fittings etc. will be embedded inside the member, the roof side and the outer wall side where it will not be visible to the human eye, etc. It is necessary to take measures such as attaching to the.

  For wooden buildings, measures are being taken to meet various demands, such as shortening the construction period and reducing the price. As one of them, parts are processed at the factory in a lump and dedicated to assembly work locally. Possible pre-cut construction methods are widely used. In this case, metal fittings are often used for joining the members, but the metal fittings and the drift pins are hit at the time of work such as fitting the metal fitting into the member or driving a drift pin penetrating the member and the metal fitting. It is necessary to apply such intense external force. This work is difficult to automate and often requires labor-intensive work, and there are problems in terms of workability and safety, especially at high places where the scaffolding is poor.

  In addition, when making a skeleton structure such as a column or a beam visible from the room, it is necessary to attach the metal fittings that join the members to the outer wall that cannot be visually recognized in consideration of aesthetics. However, when using a sheet-like exterior material such as a siding board or curtain wall on the outer wall, it is common to fix them so that they are attached to the side of the pillar, and if the brackets protrude from the pillar, The exterior material may interfere with these and cannot be fixed correctly. In order to avoid this, it is necessary to take measures such as interposing other members between the exterior material and the pillar, or embedding metal fittings in the pillar, and it is difficult to reduce costs and time because the number of processes increases. There is a problem.

  The present invention was developed on the basis of such circumstances, has excellent workability when joining members together, and can secure sufficient strength, and in addition, there is no projecting portion from the member and construction of exterior materials, etc. It is an object of the present invention to provide a member connector that can be easily implemented.

  According to a first aspect of the present invention for solving the above-described problems, a metal fitting embedded in a key groove provided in the coupling member, a hanging metal fitting attached to the main member, and a first metal plate that presses the metal fitting against the coupling member. A first pressing plate, a second pressing plate that presses the metal fitting against the main member, nails that fix the first pressing plate to the coupling member and fix the second pressing plate to the main member, and the first A fastener that integrates the pressing plate and the second pressing plate, and the metal fitting includes a belt-shaped middle plate, two side plates extending vertically from both side portions of the middle plate, and the both sides An insertion plate that folds the tip of the plate inward and extends parallel to the side plate with a gap therebetween, and the intermediate plate is provided with a round hole for penetrating the nails, The first pressing plate is composed of a strip-shaped flat plate and a contact plate extending perpendicularly from one end side of the flat plate, A drill hole for penetrating the nails is provided in the plate, an engagement hole for penetrating the fastener is provided in the backing plate, and the hanging metal fitting is formed of a belt-like middle plate and The two side plates extending vertically from both side portions of the intermediate plate, and the insertion plate extending in parallel with the side plates with a gap between the front end portions of the side plates and turning outward, The middle plate is provided with a round hole for penetrating the nails, and the second pressing plate is composed of a strip-shaped flat plate and a contact plate extending perpendicularly from one end side of the flat plate. Is provided with a drill hole for penetrating the nails, and the abutting plate is provided with a locking hole for penetrating the fastener, and the nails are formed in the drill hole of the first push plate. And through the round hole of the catch metal and is driven into the coupling member, and through the drill hole of the second pressing plate and the round hole of the hook metal. The fastener is inserted through the locking hole of the first pressing plate and the locking hole of the second pressing plate so that both the contact plates can be integrated. Fit into the gap of the other party, mesh the receiving metal fitting and the hanging metal fitting, and further integrate the first pressing plate and the second pressing plate with the fastener to connect the main member and the coupling member It is the member connection tool to be taken.

  The main member and the connecting member are names given for convenience in order to identify two members to be connected according to the present invention, both of which are wood processed into a rod shape. And in order to embed the member connector according to the present invention in either one of the contact surfaces of the main member and the coupling member, a key groove in which the member is cut into a groove shape is required. This keyway may be provided on either the main trunk member or the coupling member, but in this specification, it is provided on the coupling member. The key groove is not a closed form in which the central portion of the member surface is depressed, and one end surface of the key groove is exposed on the side surface of the coupling member, and it is necessary to provide an opening that is open to the outside. .

  The metal fitting is embedded in the key groove, and an intermediate plate formed in a strip shape so as to be in contact with the bottom of the key groove, and a side plate extending vertically from both side portions along the longitudinal direction of the intermediate plate, The left and right side plates are equal in height. Therefore, the cross-sectional shape composed of the middle plate and the side plate is substantially U-shaped, and this cross-sectional shape is continuous in the longitudinal direction without changing. Further, in order to fix the receiving metal fitting to the coupling member, a round hole for driving nails is processed in the intermediate plate. And the front-end | tip part located in the most end of the side plate extended from the side part of the middle plate is turned back so as to make a U-turn toward the inside, and the insertion plate extending in parallel with the side plate by this turn back Is formed. The side plate and the insertion plate are not in close contact with each other, and a gap is secured between them.

  The first pressing plate is used to fix the receiving bracket to the coupling member, and is composed of an elongated flat plate that can come into surface contact with the inner plate of the receiving bracket, and a contact plate formed by bending one end of the flat plate at a right angle. It is L-shaped when viewed from the side. In order to drive nails into the flat plate, a drill hole is processed at a position corresponding to the round hole of the receiving metal fitting. In addition, the contact plate is provided with a locking hole for allowing the fastener to pass therethrough, and this locking hole may be a simple hole processed by a drill or a female screw may be processed on the inner periphery.

  A nail that fits a receiving metal fitting into the keyway machined in the coupling member, and then places the first pressing plate on the keyway, and then penetrates the circular hole of the receiving metal metal from the drill hole of the first pressing plate and pierces the coupling member. When the bracket is driven, the metal fitting is fixed to the coupling member. At this time, the first pressing plate needs to direct the contact plate toward the opening of the key groove. Further, as a specific example of the nail, a screw nail may be used in addition to a simple driving-type nail.

  The hanging metal fitting is an article paired with the receiving metal fitting and is directly attached to the contact surface of the main trunk member. And it is comprised from the strip | belt-shaped intermediate | middle board which contacts a main trunk member, and the side board extended perpendicularly | vertically from the both sides of this intermediate | middle board, and the point that a cross-sectional shape is substantially U shape is not different from a receiving metal fitting. However, the end portion located at the end of the side plate extending from the side portion of the middle plate is folded back so as to make a U-turn toward the outer side opposite to the metal fitting, and this folding makes it parallel to the side plate. An insertion plate is formed extending in the direction. Again, the side plate and the insertion plate are not in close contact with each other, and a gap is secured between them. In addition, since a receiving metal fitting and a hanging metal fitting become a pair, the insertion plate formed in the both sides of the hanging metal meshes with the clearance gap formed in the both sides of the receiving metal, and further, it was formed in the both sides of the hanging metal fitting. Insertion plates formed on both sides of the metal fitting need to mesh with the gap, and the cross-sectional shapes of both need to be harmonized.

  The second pressing plate is basically the same structure as the first pressing plate. After the second pressing plate is brought into contact with the middle plate of the metal fitting, nails that penetrate both sides and penetrate the main member are driven. The hanging bracket is fixed to the main trunk member. Also, the locking holes formed in the contact plates of both pressing plates are concentric when the receiving metal fitting and the hanging metal fitting are engaged with each other, and both the pressing plates can be integrated by a fastener that penetrates both the locking holes. It is a structure. Specific examples of the fastener include a single bolt or a combination of a bolt and a nut. In the case of using a bolt and a nut, both the contact plates are sandwiched and fixed.

  By configuring in this way, the bracket is fixed to the coupling member, the latch is fixed to the main member, and then the latch is moved on the extension line of the keyway, and the other party is inserted into the gap between the two. When the plate is sandwiched, the receiving metal and the hanging metal are engaged with each other. When the hanging bracket is further moved, both the contact plates finally come into contact with each other, so that no further movement is possible. At this stage, when the first pressing plate and the second pressing plate are integrated with the fastener, the receiving metal fitting and the hanging metal fitting are completely integrated.

  Next, the invention according to claim 2 is such that the front end portions of the left and right side plates of the receiving bracket and the front end portions of the left and right side plates of the hanging bracket are inclined at the same angle with respect to the respective middle plates. When the insertion plate and the gap extend along the inclination, both insertion plates are fitted into the other party's gap, and the receiving metal fitting and the hanging metal fitting are engaged, 2. The member connector according to claim 1, wherein the distance between the two intermediate plates gradually approaches. Here, the tip of the side plate is a side plate formed by bending both sides of the middle plate at a right angle, and is the edge farthest from the middle plate, and the place that is just the boundary between the side plate and the insertion plate. It points out and extends linearly along the longitudinal direction of the metal fitting.

  In the present invention, the tip portion is configured to be inclined with respect to the middle plate, and as a result, when the metal fitting is viewed from the side, the left and right end surfaces are parallel and only the tip portion is inclined to have a side-down trapezoidal shape. The insertion plate and the gap also extend along the inclination of the tip. Needless to say, the tip portions on both the left and right sides have the same inclination, and the cross-sectional shape of the metal fitting needs to be symmetrical in the entire region. In addition, the linearly extending tip is not curved in the middle or its inclination angle does not change in the middle, it is configured in a straight line, and both the receiving bracket and the hanging bracket are inclined at the tip Are equal.

  With this configuration, when the latch is engaged with the bracket, the distance between the two intermediate plates gradually approaches due to the inclination of the tip as the movement of the latch proceeds. It becomes possible to draw the bracket to the bracket. As a result, the contact surfaces of the main member and the coupling member are pressed against each other, and the strength of the coupling portion is improved.

  As in the first aspect of the invention, the bracket is fixed to the coupling member via the first pressing plate, and the hanging bracket is fixed to the main member via the second pressing plate. By joining the two members together, the work that requires the force of pushing the hozo and metal fittings into the member as in the past becomes unnecessary, and it becomes a simple work of simply engaging the metal fittings. Workability is improved and the time can be shortened. In addition, since everything except the key groove opening cut into the coupling member is embedded in the member, even if the member is exposed indoors, it can be concealed by adjusting the arrangement of the opening. Even when an exterior material such as a curtain wall is attached to the member, since there is no portion protruding from the member in the present invention, the exterior material and the member can be easily brought into close contact with each other, and the construction can be performed without extra effort. In addition, the main member and the coupling member can be strongly pulled together by utilizing the reaction force due to the elastic deformation of the receiving metal fitting and the hanging metal fitting to ensure sufficient strength.

  As in the invention described in claim 2, both the receiving metal fitting and the hanging metal fitting are inserted into the receiving metal fitting by being configured such that the tip portion which is the outer edge of the side plate is inclined with respect to the middle plate. At this time, since the hanging fitting is drawn toward the receiving fitting along the inclination, the coupling member and the main member are brought into contact with each other in a pressed state. Therefore, it becomes possible to improve the rigidity of the connecting portion, and even when a large external force is applied due to an earthquake or the like, the strength is maintained and damage to the building can be prevented.

  FIG. 1 is a perspective view showing a shape example of a member connector according to the present invention. However, each part is drawn separately. The metal fitting 11 is formed by bending a metal plate, and a belt-like rectangular portion located in the center is the middle plate 12. Both side portions along the longitudinal direction of the intermediate plate 12 are bent at a right angle to form a side plate 13 extending vertically. The side plates 13 have the same shape on the left and right sides, and the height of the side plates 13 is constant. Moreover, the front-end | tip part 17 located in the upper edge of the side board 13 is bent so that it may make a U-turn toward the inner side, and the insertion board 14 which turned the front-end | tip down is formed there. The insertion plate 14 extends in the longitudinal direction in the same manner as the side plate 13, and the cross-sectional shape of the receiving metal fitting 11 remains unchanged everywhere. The side plate 13 and the insertion plate 14 are slightly separated from each other and a gap 15 is formed. In addition, a plurality of round holes 16 for allowing the nails 52 to pass therethrough are machined in the center of the intermediate plate 12.

  The coupling member K is processed with a key groove 53 for embedding the metal fitting 11, and the width thereof is adjusted to the width of the intermediate plate 12 so that the metal fitting 11 can be easily press-fitted. As for the length, it is necessary to secure the space near the opening 54 after the receiving metal 11 is completely accommodated, which is larger than the total length of the intermediate plate 12. In addition, the depth of the keyway 53 is determined by the shapes of the receiving metal 11 and the hanging metal 31. Next, the first pressing plate 21 is formed in an L shape when viewed from the side surface by bending only one end of a belt-like flat plate 22 at a right angle to form a contact plate 23. A plurality of drill holes 24 are formed in the flat plate 22, and the drill holes 24 correspond to the round holes 16 of the receiving metal fitting 11. In addition, the locking hole 25 processed in the contact plate 23 is not a simple hole processed by a drill or the like, but a female screw is processed in the inner periphery so that it can be screwed into the fastener 51.

  The hanging metal fitting 31 paired with the receiving metal fitting 11 is also formed by bending a metal plate, and side plates 33 extend vertically downward from both side portions of the belt-like middle plate 32, and a tip portion 37 located at the bottom is formed. , And bent so as to make a U-turn toward the outside over the entire region in the longitudinal direction. Accordingly, an insertion plate 34 extending upward from the distal end portion 37 is formed, and a gap 35 is secured between the side plate 33 and the insertion plate 34. A plurality of round holes 36 for allowing the nails 55 to pass therethrough are also formed in the center plate 32 of the hanging metal 31 in the center. In addition, the second pressing plate 41 is basically composed of a flat plate 42 and a contact plate 43 as in the case of the first pressing plate 21. The flat plate 42 has a drill hole 44, and the contact plate 43 has a locking hole 45. The locking hole 45 is a simple hole for allowing the fastener 51 to pass therethrough.

  After press fitting the receiving metal 11 into the keyway 53, the first pressing plate 21 is placed on the middle plate 12. At this time, the contact plate 23 faces the opening 54 and the position is adjusted so that the drill hole 24 and the round hole 16 are concentric. Next, when the nails 52 are driven from the drill hole 24 toward the coupling member K, the receiving metal fitting 11 is sandwiched and fixed by the first pressing plate 21 and the coupling member K. Similarly, after the hanging metal fitting 31 is brought into contact with a predetermined position of the main trunk member S, the second pressing plate 41 is placed on the intermediate plate 32, and then the round hole 36 and the drill hole 44 are aligned to be concentric and the nails 55 are arranged. Is driven toward the main member S, the hook 31 is sandwiched between the second pressing plate 41 and the main member S and fixed.

  The receiving metal 11 and the hanging metal 31 can be integrated, so that the insertion plate 34 of the hanging metal 31 enters the gap 15 of the receiving metal 11, and the insertion plate 14 of the receiving metal 11 is the gap of the hanging metal 31. Both dimensions have been adjusted to fit into 35. Accordingly, when the hanging metal fitting 31 is engaged with the receiving metal fitting 11, the movement in the direction other than that becomes impossible, and when the engagement is further advanced, the contact plates 23, 43 of the two pressing plates 21, 41 are in contact with each other. To do. Thereafter, by inserting bolts 51 (fasteners) from the locking holes 45 of the second pressing plate 41 and screwing them into the locking holes 25 of the first pressing plate 21, both the pressing plates 21, 41 can be integrated. Thus, the receiving metal 11 and the hanging metal 31 are completely integrated.

FIG. 2A shows a state in which the hanging bracket 31 is fixed to the main member S, and FIG. The state fixed to the coupling member K is shown. The hanging bracket 31 is in contact with the side surface of the main trunk member S and is fixed together with the second pressing plate 41 by nails 55. Further, the metal fitting 11 is embedded in a key groove 53 machined on the end face of the coupling member K, but the key groove 53 is formed longer than the receiving member 11, and is received near the opening 54. The metal fitting 11 does not exist. In FIG. 2, when the hanging metal fitting 31 is turned upside down and inserted into the receiving metal fitting 11 with the abutting plate 43 of the second pressing plate 41 at the tail end, both can be engaged with each other.

  FIG. 3 is a perspective view showing a process in which the receiving bracket 11 and the hanging bracket 31 are integrated, and FIG. 3A shows a state immediately before the hanging bracket 31 and the receiving bracket 11 come into contact with each other. FIG. 3B shows a state in which the hanging bracket 31 has been inserted to about half, and FIG. 3C shows a state in which the insertion of the hanging bracket 31 has been completed. Both dimensions are adjusted so that the insertion plate 34 of the hanging bracket 31 is sandwiched in the gap 15 of the receiving bracket 11 and the insertion plate 14 of the receiving bracket 11 is sandwiched in the gap 35 of the hanging bracket 31. As shown in FIG. 3 (A), after both positions are aligned, when the hanging bracket 31 is moved closer to the receiving bracket 11, both will eventually engage, but if the movement continues in that state, FIG. 3 (B). When the movement further proceeds, as shown in FIG. 3C, the contact plates 23 and 43 of both pressing plates 21 and 41 come into contact with each other, and when the bolts 51 are inserted, The receiving metal 11 and the hanging metal 31 are integrated by screwing into the female screw of the stop hole 25. In addition, it is necessary to design the processing position of the locking holes 25 and 45 of both the pressing plates 21 and 41 to be concentric in the state of FIG.

As shown in FIG. 4A, the receiving metal 11 and the hanging metal 31 are engaged with each other, so that the main member S and the connecting member K are attracted and are firmly connected. The nails 52 and 55 are driven from the push plates 21 and 41 into the main member S or the connecting member K. The receiving metal 11 is integrated with the connecting member K, and the hanging metal 31 is integrated with the main member S. Note that the depth of the key groove 53 needs to match the height when the receiving metal 11 and the hanging metal 31 are engaged with each other as shown in FIG. 4B, the first pressing plate 21 and the second pressing plate 41 are integrated by a bolt 51, and the head of the bolt 51 is accommodated in the key groove 53. There is nothing protruding outside the keyway 53, and everything except the opening 54 of the keyway 53 is embedded in the main member S and the coupling member K.

  FIG. 5 is a perspective view showing the configuration when the front end portions 17 and 37 are inclined with respect to the intermediate plates 12 and 32 in both the receiving metal 11 and the hanging metal 31. FIG. 5A shows a single shape of the receiving metal 11 and the hanging metal 31, and the tip end portions 17 and 37 are inclined with respect to the two-dot chain line parallel to the middle plates 12 and 32, and as a result. The insertion plates 14 and 34 and the gaps 15 and 35 are also tilted accordingly. The inclination is the same on both the left and right sides, and the inclination angles of the receiving metal 11 and the hanging metal 31 are equal. FIG. 5B is an initial stage in which both are engaged, and FIG. 5C shows a state in which the hook 31 is moved therefrom, and FIG. 5D shows a final stage. In FIG. 5B, FIG. 5C, and FIG. 5D, the height H of the receiving metal 11 and the hanging metal 31 is gradually lowered due to the inclination.
