Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connection structure between a joist and a supporting member, which improves the workability of connecting the joist and a supporting member that receives the joist on a balcony or the like.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Connections between joists on balconies, terraces, solariums, etc. and supporting members such as joists and girders that receive the joists are generally located on the joist side from the supporting members as in JP-B-58-40167 and JP-B-59-7921. It is done by stacking a joist mounting piece on the protruding support piece and tightening the nut on the bolt penetrating both, but the tightening is done from directly above or below the support piece, and at a position close to the support member. Workability is poor because the work is done in the same way, especially when the door pocket is installed on the support member on the wall side, work is done only from below, and workability is significantly reduced, and tightening of all bolts and nuts is completed. It takes a long time to get there.

This invention was made with a focus on the problem of workability of connecting joists and supporting members, and is intended to newly propose a workable connection structure.

[0004]

[Means for Solving the Problems]

 In the present invention, the mounting piece located on the joist side of the support member of the support member is inclined downward from the support member side to the joist side, and at the same time, the notch is formed at the position corresponding to the mounting piece of the joist mounting piece. Insert the connecting material that connects the two from this notch, and stack and connect it to the supporting piece to tilt the screwing direction of the screw with respect to the vertical, and work on the joist near the middle part. Secures space and enhances connection workability.

The connecting member is composed of a base portion that overlaps the mounting piece of the joist and a mounting portion that penetrates the notch and overlaps the mounting piece of the supporting member. The connecting member is inserted from the notch of the mounting piece of the joist and supports the mounting portion and the supporting portion. The joist is connected to the support member while being sandwiched between the support member and the joist by being connected by a screw penetrating the attachment piece of the piece.

A mounting piece that inclines downward from the support member side to the joist side is connected to a mounting portion that overlaps with this, and the screwing direction of the screw inclines from the joist side to the support member side from top to bottom. By doing so, the place for connecting work is secured on the joists, closer to the joists than the support member, and the work becomes easier. Even when the door pocket is installed on the support member, there is no interference between the door pocket and the working space, which allows work on the joists and also when tightening bolts when using bolts as screws. Space is secured, and the efficiency of connecting work is improved.

Further, an engaging portion that engages upward with the attaching piece of the support member is formed in the attaching portion of the connecting member, and the connecting member is engaged with the supporting member upward to blow up the joist from below. Resistance to force increases.

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment.

As shown in FIG. 1, the present invention is installed between a supporting member 2 having a supporting piece 21 protruding to the joist 1 side and supporting members 2 and 2, and is mounted on the supporting piece 21 of the supporting member 2, A joist 1 having overlapping mounting pieces 11 is connected using a connecting member 3.

The mounting piece 211 located on the joist 1 side of the supporting piece 21 of the supporting member 2 is inclined downward from the supporting member 2 side to the joist 1 side as shown in FIG. The connecting member 3 is connected to the screw with the screw 4. The attachment pieces 211 are spaced in the lengthwise direction, and insertion holes 212 are opened corresponding to the installation position of the joist 1.

A notch 111 is formed in the mounting piece 11 of the joist 1 at a position corresponding to the mounting piece 211, and the connecting member 3 is superposed on the mounting piece 211 of the support member 2 from the notch 111 and the screw 4 is attached. The screwing work is performed. 3 shows a case where the notch 111 is formed in an opening shape, and FIG. 4 shows a case where the notch 111 is formed from the tip of the mounting piece 11 in the prospective direction.

As shown in FIGS. 1 and 5, the connecting member 3 includes a base portion 31 that overlaps the mounting piece 11 of the joist 1 and a mounting portion 32 that penetrates the notch 111 and overlaps the mounting piece 211 of the support member 2. The base 31 sandwiches the mounting piece 11 between the supporting piece 21 and the mounting portion 32, and the supporting member is screwed into the insertion hole 321 opened in this and the insertion hole 212 opened in the mounting piece 211. Since the joist 1 is connected to the support member 2, the joist 1 is connected to the support member 2. The base portion 31 is formed on both sides of the attachment portion 32 for holding the joist 1.

FIG. 6 shows a case where the support piece 21 of the support member 2 is bent upward. In this case, the tip of the mounting piece 211 inclined with respect to the horizontal plane is further bent horizontally, and this horizontal portion The joist 1 is placed on the base 3, and the attachment piece 11 of the joist 1 is sandwiched together with the base 31 of the connecting member 3. As a result, the support piece 21 can be used as a drain gutter.

In FIG. 7, as shown in FIG. 9, an engaging portion 33 that engages upward with the attaching piece 211 of the supporting piece 21 is formed in the attaching portion 32 of the connecting member 3, and the attaching piece 211 is attached to the engaging portion 33. The embodiment shows a case in which the two members are secured to each other by fitting them, and the resistance of the connecting member 3 to the upward blowing force acting on the joist 1 is increased. When the support piece 21 of the support member 2 is cut by the attachment piece 211 as in the embodiment shown in FIG. 1, the tip of the attachment piece 211 fits into the engaging portion 33, but in the case of the embodiment shown in FIG. Since the support piece 21 continues to the lower side of the attachment piece 211, the projection 213 fitted to the engaging portion 33 is projected on the attachment piece 211 of the support piece 21 of the support member 2 as shown in FIG. To be done.

[Effect of device]

 The present invention is as described above, and the mounting piece located on the joist side of the supporting piece of the supporting member is inclined downward from the supporting member side to the joist side, and at the same time, corresponds to the attaching piece of the joist mounting piece. Since a notch is formed at the position where the screw is inserted, a connecting material that connects the two is inserted from this notch, and this is stacked and connected to the support piece, so that the screw is screwed in from the top to the bottom. Side to support member side, connection work can be done on joists, closer to joists than support members, and in addition to improving workability, the work space is expanded, making it easier to use an electric drill and improving work efficiency. Can be raised. Even when the door pocket is installed on the support member, workability is maintained because work on the joists is possible.

Further, an engaging portion that engages upward with the attaching piece of the supporting member is formed in the attaching portion of the connecting member, and the connecting member is engaged with the supporting member upward to blow up the joist from below. Resistance to force is increased.
