Description

  The present invention relates to a joining structure for joining two members.

  As a joining structure of two members, for example, a joining structure that joins two members by screwing a screw entering from one member side of two overlapping members to the other member is known.

  In the joining structure as described above, since the two members before joining only overlap, when the screw entering from one member side is screwed to the other member, the other member is pushed by the screw. If it moves in a direction away from one member, the screw cannot be screwed into the other member. For this reason, the operator needs to hold down the other member in the direction opposite to the entry direction of the screw while allowing the screw to enter from one side. For this reason, when the members located at high places are fixed by allowing screws to enter from below, or when the side opposite to the side where the screws enter is blocked by another member, There is a problem that the opposite member cannot be pressed and the two members cannot be joined by work from one side.

  This invention is made | formed in view of this subject, The place made into the objective is to provide the joining structure which can join two overlapping members easily by the operation | work from one side.

In order to achieve such an object, the joining structure of the present invention is a joining structure in which a second member that overlaps with the first member is joined by screwing a screw that enters from the first member side to the second member, The first member and the second member each have a plurality of entry direction facing portions facing each other in the entry direction at positions spaced from each other in a crossing direction intersecting the entry direction of the screw, the entering direction opposing portion of said second member, in the in the entering direction from the approach direction opposite portion disposed on the front side the state of the first member and the first member and the second member is joined The entry direction facing portion of the first member and the entry direction facing portion of the second member are opposed to each other with an interval in a state where the first member and the second member are joined, The entry direction facing portion of the first member and the second member The distance from the entry direction facing portion is such that the second member is pressed in the entry direction by the screw screwed into the second member, and the entry direction facing portion of the second member is the first member. This is a joining structure characterized in that the screws are spaced so as to be able to be screwed into the second member in a state of being in contact with the entry direction facing portion .

  According to such a joining structure, in the state where the first member and the second member are joined to each other, the first member and the second member that are overlapped by the first member and the second member that overlap each other are in the second direction. Since the entry direction facing portion of the member is disposed on the near side in the entry direction from the entry direction facing portion of the first member, when the screw is screwed into the second member, the second member is moved in the entering direction by the screw. Even if pushed, the movement of the second member toward the entry direction is restricted by engaging the entry direction facing portion of the second member with the entry direction facing portion of the first member. For this reason, it is possible to easily join the first member and the second member by work from the first member side without pressing the second member to the first member side. At this time, since the plurality of approach direction facing portions provided in the first member and the second member face each other in the approach direction at positions spaced apart from each other in the intersecting direction, even if pressed by a screw, the second The member is not greatly inclined with respect to the first member. For this reason, it is possible to join the first member while maintaining the stable state of the second member.

Further , before the first member and the second member are joined, the second member is pressed by the screw, and the second member is engaged with the entry direction facing portion of the second member to the entry direction facing portion of the first member. Even if it moves to the position where it fits, since the screw can be screwed onto the second member, it is possible to reliably join the first member and the second member.

  In this joining structure, the first member and the second member each have a cross direction facing portion that faces each other in the cross direction, and the approach direction facing portion of the first member is the first member A first member raised portion projecting from the intersecting direction facing portion of the member toward the intersecting direction facing portion of the second member and projecting toward the entering direction facing portion of the second member; The entry direction facing portion of the member protrudes from the intersecting direction facing portion of the second member toward the intersecting direction facing portion of the first member and rises toward the entering direction facing portion of the first member A second member bulging portion, wherein the first member bulging portion has the second member bulging portion in which the first member bulging portion is opposite to the entry direction of the first member. Tip from the position facing the part It is desirable that located.

  According to such a joining structure, in the state where the first member and the second member are joined, the first member raised portion is a position where the approaching direction facing portion of the first member faces the second member raised portion. It is located on the tip side. At this time, the second member raised portion is located on the distal end side from the position where the approach direction facing portion of the second member faces the first member raised portion. For this reason, when the first member and the second member are joined, if the approach direction facing portion of the second member engages the approach direction facing portion of the first member, the first member raised portion and the second member raised portion Since the relative movement in the crossing direction of the first member and the second member is restricted by the portion and the engagement between the first member and the second member is difficult to disengage, the first member and the second member can be more easily Can be joined.

  In this joining structure, in the approach direction, a screw guide portion formed so as to gradually narrow toward the screwing portion is provided in front of the screwing portion of the screw provided in the second member. It is desirable that

  According to such a joining structure, before the screw entering from the first member side is screwed into the screw screw portion of the second member, the screw guide portion provided in front thereof is engaged. The engaged screw guide is formed so that it gradually narrows from the near side toward the far side, so that the first member and the second member are placed at appropriate positions and joined by inserting the screw. Is possible.

  In this joining structure, at least one of the entry direction facing portion of the first member or the entry direction facing portion of the second member is the first member raised portion or the second member raised portion. The first member raised portion or the second member raised portion into the depression by the inclined surface when the screw is tightened. It is desirable that the first member and the second member are positioned by being guided.

  According to such a joining structure, the first member or the second member in the approach direction facing portion is connected to the first member raised portion or the second member raised portion by the inclined surface and is recessed toward the opposite side of the raised direction. Therefore, when the first member and the second member are joined, the first member raised portion or the second member raised portion can be joined while being guided by the depression connected by the inclined surface. It is. For this reason, it is possible to position and join the first member and the second member more accurately.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide the joining structure which can join the two overlapping members easily by the operation | work from one side.

Therefore, the new outer upper frame 142 and the upper frame 17 can be easily joined only by screwing the screw 20 from below without the upper frame 17 being pressed from above by the operator.

  At this time, before the new outer upper frame 142 and the upper frame 17 are joined, the upper frame 17 is pressed by the screw 20, so that the upper frame 17 becomes the upper cover extending piece 171 o and the lower extending portion of the upper frame 17. Even if 171v moves to the position where it engages with the outer projecting piece 142i and the inclined extending piece 142f of the new outer upper frame 142, the screw 20 can be screwed into the upper frame 17, so that it can be reliably installed by work from one side. The outer upper frame 142 and the upper frame 17 can be joined. In particular, when two members are joined at a high position by work from below as in the present embodiment, it is not necessary to press the member from above, which is difficult to reach, so that it can be attached more easily.

  Further, the outer projecting piece 142i and the inclined extending piece 142f provided on the new outer upper frame 142, and the upper cover extending piece 171o and the lower extending portion 171v provided on the upper frame 17 are spaced from each other in the prospective direction. Since the upper and lower frames 17 are opposed to each other at the separated positions, the upper frame 17 pressed by the screws 20 does not largely tilt with respect to the newly installed outer upper frame 142. For this reason, it is possible to join the newly installed outer upper frame 142 while maintaining the upper frame 17 in a stable state.

  Further, the screw 20 entering from the newly installed upper frame 142 side engages with a screw guide portion 171t provided in front of the screw 20 before being screwed into the screw screw portion 171p of the upper frame 17. The engaged screw guide portion 171t is formed so as to gradually become narrower from the near side toward the far side, so that the new outer upper frame 142 and the upper frame 17 can be appropriately connected by screwing and tightening the screws 20. It is possible to arrange and join at various positions.

  Further, in the state where the new outer upper frame 142 and the upper frame 17 are joined, the frame protruding portions 142k and 142l are tips from positions facing the frame protruding portions 171r and 171s in the outer protruding piece 142i and the inclined extending piece 142f. Located on the side. At this time, the frame raised portions 171r and 171s are located on the distal end side from the position where the upper cover extending piece 171o and the lower extending portion 171v face the frame raised portions 142k and 142l. For this reason, when the new outer upper frame 142 and the upper frame 17 are joined, the upper cover extending piece 171o and the lower extending portion 171v of the upper frame 17 are extended to the outer projecting piece 142i and the inclined extension of the new outer upper frame 142. When engaged with the protruding piece 142f, the frame protruding portions 142k and 142l and the frame protruding portions 171r and 171s restrict relative movement of the new outer upper frame 142 and the upper frame 17 in the crossing direction, and the new outer upper frame 142 and Since the engagement with the upper frame 17 is difficult to disengage, it is possible to join the new outer upper frame 142 and the upper frame 17 more easily.

  Further, since the upper frame 17 is provided with a recess 171q that is connected to the frame protruding portion 171s and the inclined surface 171u at the tip of the lower extending portion 171v and is recessed on the opposite side to the protruding direction, When the upper frame 17 is joined, the frame raised portion 142l can be joined while being guided by the depression 171q connected by the frame raised portion 171s and the inclined surface 171u. For this reason, it is possible to position and join the new outer upper frame 142 and the upper frame 17 more accurately.

  In the above embodiment, the example in which the frame ridge 171s provided in the lower extension 171v and the depression 171q connected by the inclined surface 171u has been described, but the depression includes the outer projecting piece 142i and the inclined extension piece 142f. The upper cover extension piece 171o may be provided, or may be provided at a plurality of locations.

  Moreover, although the said embodiment demonstrated the example which provided the site | part which opposes the approach direction of the screw | thread 20 at intervals in the cross direction, it was not restricted to two places. Moreover, in the said embodiment, although the site | part which opposes the approach direction of the screw | thread 20 was arrange | positioned so that the screw | thread screwing part 171p may be pinched | interposed in the cross direction, it was not necessarily provided in the both sides of the screw screwing part. It does not have to be.

  In the above embodiment, the two members to be joined are the new upper frame 14 and the upper frame 17. However, the present invention is not limited to this, and two members such as a decoration material attached to a frame of a joinery, a veranda, a carport, and the like. Any member may be used as long as the members are joined by screws entering from one side.

  Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
