Description

  The present invention relates to a frame structure and a method for assembling the frame structure. More specifically, the present invention relates to a frame structure configured to include two frame members, and a frame structure assembling method for fixing two frame members.

  In a terrace, a car port, a gate, etc., the frame structure comprised by fixing long frame materials is used in many cases. Most of the frame members used in this frame structure are extruded members of long aluminum, and these frame members are provided in the connecting member after being inserted into a part or all of the connecting member. The bolt from the outer side of the frame is screwed into the screw hole being fixed. Patent Document 1 discloses a connecting member and an aluminum post on which the connecting member is fitted and fixed at an end. In addition, in the frame structure such as a gate, it is avoided to separately provide a connecting member outside the frame material as much as possible.

  Here, FIGS. 4 and 5 show a conventional frame structure assembling method. FIG. 4 is an explanatory view of a conventional frame structure assembling method, and FIG. 5 shows the frame structure in a state of being assembled by this frame structure assembling method.

  Conventionally, when assembling a frame structure as shown in FIG. 4 and FIG. 5, first, the joint fitting 58 is connected to the side surface of the hollow second frame member 53. In this case, a back plate 54 having a screw hole is provided on the inner side surface of the second frame member 53, and the joint fitting 58 is fixed by a bolt from the outside of the second frame member 53. Next, the fitting 58 is inserted into the end of the first frame member 52, and the bolt 55 is inserted from the hole 52a in the upper surface of the first frame 52 into the screw hole 58a provided in the fitting 58. At the same time, by inserting the bolt 55 from the lower surface and fixing the first frame member 52 to the joint fitting 58, a frame structure as shown in FIG. 5 can be assembled.

  However, in the conventional frame structure, since the first frame member 52 can not be fixed while being attracted to the second frame member 53 side, the space between the first frame member 52 and the second frame member 53 can not be fixed. There is a problem that a gap easily occurs. In order to solve this problem, it is necessary to tighten the bolt 55 on the upper surface of the first frame member 52 while maintaining the first frame member 52 and the second frame member 53 in close contact with each other. As described above, it takes a lot of work time to correctly assemble a conventional frame structure.

  As shown in FIG. 1, the first frame member 2 provided horizontally is an extruded section of aluminum in which the cross section in the direction perpendicular to the longitudinal axis of the first frame member 2 is substantially T-shaped. is there. Although not shown in the drawings, on the upper surface of the first frame member 2, two insertion holes for the screw portion of the bolt 5 screwed to the joint metal fitting 8 are provided, and in the lower portion of the T-shaped cross section In this case, one insertion hole for the threaded portion of the bolt 6 screwed to the joint fitting 8 from below is provided. In addition, the dimension of the 1st frame material in this embodiment is 100-200 mm in front-back length, 120 mm in up-and-down length, and left-right length is 1300-2800 mm.

  Similarly to the first frame member 2, the second frame member 3 standing vertically from the ground is also an extruded material of aluminum. The cross section perpendicular to the longitudinal axis of the second frame member 3 is one in which a U-shape is added to one side of the square. The U-shaped portion is a vertical groove. On the left side of the second frame member 3, that is, on the side face in the direction to be connected to the first frame member 2, the head of the bolt 4 or a bolt head insertion hole 4a through which a washer used by the bolt 4 can be inserted Two places are provided. In addition, the dimension of the 2nd frame material in this embodiment is 100-200 mm in front-back length, 100 mm in left-right length, and 2800 mm in up-down length.

  The spacer 7 is made of steel having a thickness of about 3.2 mm. The spacer 7 is provided with two notches 7 a corresponding to the screw portion of the bolt 4. The notch 7 a has a shape in which the lower half of the long hole shape which is long in the vertical direction is eliminated, and the diameter of the short direction of the long hole shape is larger than the thickness of the screw portion of the bolt 4. The value is smaller than that of the head, specifically about 8 mm. In the spacer 7, the opening of the notch 7a is directed downward, and the shape of the spacer 7 is substantially T-shaped. The shape of the spacer 7 is substantially T-shaped, and the lower projecting portion stabilizes the posture when the spacer 7 is hooked on the bolt 4.

  Also, the spacer 7 is used integrally with the two bolts 4. Since the spacer 7 is bridged to the two bolts 4, the spacer 7 can be stabilized in the posture in which the spacer 7 is bridged before the screwing process also at this point. At the time of screwing process, it is not necessary to consider the posture of the spacer 7, and the working efficiency is improved.

  In addition, in this embodiment, although the spacer 7 was a thing of the structure used with respect to the two bolts 4 integrally, it is not limited to this. For example, the configuration can also be used for each of the single bolts 4. As such a spacer, the structure etc. in which one notch 7a was provided in the rectangle correspond etc. correspond.

  The fitting 8 is made of steel. The fitting 8 has a shape that can be fitted into the first frame member 2. Although not shown in the drawing, a screw hole is provided on the upper surface of the joint metal fitting 8 so that the bolt 5 can be screwed in, and the bolt 4 is provided on the side surface of the joint metal fitting 8 facing the second frame member 3 A screw hole which can be screwed in is provided, and a screw hole which can screw in the bolt 6 is provided in the lower surface.

A frame structure assembling method according to an embodiment of the present invention will be described.
First, a joint fitting fixing step of fixing the joint fitting 8 to the end portion of the first frame member 2 is performed. The joint fitting 8 is inserted from the side end surface of the first frame member 2 and fixed by bolts 5 and 6 from above and below the joint fitting 8. At this time, the surface of the joint metal fitting 8 opposed to the second frame member 3 is completely identical to the side end face of the first frame member 2 or a position where the surface slightly penetrates from the side face of the first frame member 2 Fix it with

  Then, a bolt preparing step is performed in which the bolt 4 is screwed into a screw hole in the surface of the joint metal fitting 8 facing the second frame member 3. At this time, the bolt 4 is not screwed to the end but is screwed in a state in which a screwing allowance is left. Specifically, the screw-in allowance is a value obtained by adding 1 to 2 mm to a value obtained by adding the thickness of the side surface of the second frame member 3 and the thickness of the spacer 7.

  Next, a drilling process is performed in which the bolt head insertion holes 4 a are provided on the side surfaces of the second frame member 3. As described above, since the bolt head insertion holes 4a are not provided in advance on the side surface of the second frame member 3 to be subjected to drilling processing, the same second member 3 disposed on the left and right sides should be used. It is possible to reduce the types of parts used. Further, since the second frame members disposed on the left and right sides are the same member, it is not necessary to confirm which of the left and right members is disposed, and the construction becomes easy. Furthermore, since the drilling process is performed on site, it is possible to easily change the design, such as additionally fixing the first frame member to the second frame member.

  Next, the insertion step is performed. In the insertion step, the head of the bolt 4 protruding from the end of the first frame member 2 is provided on the side surface of the second frame member 3 in a state in which a screwing allowance is left in the joint fitting fixing step. The head insertion hole 4a is inserted. The bolt head insertion hole 4a has a size that allows insertion of the head of the bolt 4 or a washer used in the bolt 4. Specifically, according to the longest diagonal diagonal of the hexagonal shape in the head of the bolt 4. It also has a diameter that is a few mm longer, or a diameter that is a few mm longer than the diameter of the washer used for the bolt 4.

  After carrying out the insertion step, the spacer holding step for holding the spacer 7 is carried out. In the insertion step, the first frame member 2 and the second frame member 3 are in contact with each other without leaving a space, and the spacer 7 is sandwiched between the head of the bolt 4 and the inner surface of the second frame member 3. There is enough space. The spacer 7 is inserted from above into this gap.

  After the spacer sandwiching process is performed, the screwing process is performed. In the screwing step, a spanner is inserted from the upper end of the second frame member 3, and the bolt 4 is screwed in using this to fix the first frame member 2 and the second frame member 3.

  After fixing the first frame 2 and the second frame 3 in the screwing process, the end face cap 9 is attached to the upper end face of the second frame member 3. This completes the assembly of the frame structure.

  The frame structure is assembled by the process as described above, that is, the direction of screw tightening performed in the screwing process is a direction in which the first frame member 2 and the second frame member 3 are in close contact with each other. There is no gap between the frame member 2 and the second frame member 3, and the frame structure can be assembled accurately.

  Further, the first frame member 2 is a hollow member, and the joint metal fitting 8 having a screw hole into which the bolt 4 is screwed is fixed to the first frame member 2, thereby the first frame member 2 and the joint The bracket 8 can be made of a different material. Specifically, by setting the material of the first frame member 2 to aluminum, the weight of the frame structure can be reduced as compared to the case of using a steel material. Further, by making the fitting 8 made of steel, it is possible to increase the strength of the screw structure of the screw hole portion. Thereby, since the strength of the screw hole of the joint fitting can be secured, it is possible to prevent the bolt from being loosened.

  In the present embodiment, the first frame member 2 is also described as a hollow member like the second frame member 3, but it is not particularly limited, and a solid structure can also be used. In this case, the side end face of the first frame member 2 is directly provided with a screw hole, and the bolt 4 is screwed into the screw hole in a state where a margin is left.

  By providing the first frame member 2 with a screw hole into which the bolt 4 is screwed, the joint fitting 8 can be omitted, and the number of parts can be reduced.

  When the first frame member 2 is made of aluminum having a solid structure, it is preferable to insert a helisert in the screw hole to increase the strength of the screw hole.

  Further, in the present embodiment, the second frame member 3 is erected vertically on the ground to form the frame structure, but the present invention is not limited to this, and the second frame member 3 is a frame that constitutes a frame. It only needs to be one of the materials. For example, there is no problem even with a frame structure such as a gate.

  Furthermore, although this embodiment demonstrated the case where it connected with the 1st frame material 2 in the vicinity of the upper end surface of the 2nd frame material 3, it is not limited to this. For example, if the bolt 4 is a hex socket bolt, a hex wrench hole is provided on the side opposite to the side where the bolt head insertion hole 4a is provided, and the bolt 4 is tightened from that part with the hex wrench. Assembly is possible even at a distance from the upper end face.
