Description

  The present invention relates to a connection structure of extruded shape members that form a panel body suitable for a fence, a gate, or the like by connecting a plurality of extruded shape members.

Conventionally, as shown in FIG. 6, there is known one in which an extruded shape member A is continuously provided in the vertical direction or the horizontal direction and used as a panel body such as a fence or a gate. The extruded shape member A has a male joint portion B formed on one side edge, the male joint portion B has a screw wall portion B1 and a screw hole B2 surrounded by the screw wall portion B1, and an extruded portion adjacent to the other side edge. A female joint portion C having a fitting wall portion C1 that is externally fitted to the screw wall portion B1 of the profile A is formed.
In such an extruded shape A, the female joint portion C of the other extruded shape member A is externally fitted to the male joint portion B of one of the adjacent extruded shape members A, and a through hole of a frame member (not shown). Is screwed into the screw hole B2 of the male joint portion B, so that the extruded member A is fixed to the frame member, and a panel body in which the extruded member A is continuously provided is formed. Since the female joint portion C is externally fitted to the male joint portion B of the adjacent extruded shape member A, the extruded shape member A can be attached to the frame member in a non-rotatable manner by one screw member D. The number of screw members D and assembly man-hours can be reduced.

However, in order to connect the adjacent extruded shape members A, the female joint portion C must be externally fitted to the male joint portion B, and the inner diameter of the fitting wall portion C1 is larger than the outer diameter of the screw wall portion B1. It is necessary to form a large. Therefore, a gap is generated between the outer periphery of the screw wall portion B1 and the inner periphery of the fitting wall portion C1, and the extruded shape member A in which the screw hole B2 positioned on one side edge is screwed is subjected to wind pressure or vibration. The screw wall B1 and the fitting wall C1 collide with each other and cause the generation of abnormal noise.
In particular, when used as a panel of a gate, abnormal noise is generated due to vibration of the opening and closing operation of the gate, which deteriorates the quality.

  Patent Document 1 discloses a joining structure of extruded shape members and a joining reinforcing material, which increases the bonding strength between the extruded shape member and the frame member when the extruded shape member is attached to the frame member or the like. However, the side edges of the adjacent extruded shapes are connected to each other and the connection strength is not increased. Further, in order to increase the bonding strength, a bonding reinforcing material is required separately from the extruded shape member.

JP 2000-130421 A

  An object of the present invention is to provide a connection structure of extruded shapes that enhances the connection strength between adjacent extruded shapes, suppresses the generation of noise in the connection portion due to rattling, and enhances the quality.

Forming a male joint, the male joint having an opposingly formed screw wall, a screw hole surrounded by the screw wall, and an opening formed between the tips of the screw wall; A female joint portion is formed on the other side edge of the profile, and the female joint portion is externally fitted and surrounded by a fitting wall portion wider than the outer circumference of the screw wall portion of the male joint portion; It has a protrusion that engages with the opening of the male joint, and the female joint of the other extruded shape is fitted into the male joint of one of the extruded shapes. By screwing the screw member into the screw hole of the male joint portion, the protruding portion engaging the opening is pushed outward by the screw member, and the fitting wall The inner circumferential surface by which is crimped to the outer peripheral surface of the screw wall of, is obtained by achieving the intended purpose.

  In the invention according to claim 2, the screw member is inserted into the screw hole of the male joint portion through the through hole of the frame member, and the extruded shape member is attached to the frame member. Strength can be improved and it can be made suitable as panels, such as a fence and a gate.

According to the extruded shape member connection structure of the present invention, the male joint portion formed on the one side edge of one of the adjacent extruded shape members has the female joint portion formed on the other side edge of the other extruded shape member. The external fitting is surrounded and the screw member is screwed into the screw hole of the male joint portion, so that the protruding portion of the female joint portion that engages the opening of the male joint portion is moved outward by the screw member. Extruded, and the inner peripheral surface of the mating wall is crimped to the outer peripheral surface of the screw wall, so that the extruded shapes can be connected together without backlash, suppressing abnormal noise due to wind pressure and vibration, and between quality Can be uplifted.

  In addition, although the ridge that engages the opening is pushed outward by the screw member, the screw member remains inside the screw wall, so the ridge does not completely detach from the opening, The movement of the ridge portion is restricted by the tip end portion of the screw wall portion, and the mutual rotation of the male joint portion and the female joint portion can be prevented.

Hereinafter, the best mode for carrying out the present invention will be described based on examples.
FIG. 1 to FIG. 5 show a connection structure of extruded shape members according to the present invention, and shows an example in which a continuous extruded shape member is applied to a fence panel. In the figure, 1 is an extruded shape member made of aluminum and has a substantially U-shaped cross section. The extruded shape member 1 may be made of a material other than aluminum, such as a resin.

A male joint portion 2 is formed on one side edge of the extruded shape member 1, and a female joint portion 3 is formed on the other side edge. The male joint portion 2 has an opposing screw wall portion 21, a screw hole 22 surrounded by the screw wall portion 21, and an opening portion 23 having a space between the tip portions of the screw wall portion 21.
On the other hand, the female joint portion 3 has a fitting wall portion 31 formed so as to face the opening portion 32 and a protrusion 33 formed on the bottom portion facing the opening portion 32.

Such an extruded shape member 1 is connected by externally fitting and surrounding the female joint portion 3 of the other extruded shape member 1 to the male joint portion 2 of the one adjacent extruded shape member 1. More specifically, the fitting wall portion 31 of the other extruded shape member 1 is externally fitted to and surrounded by the screw wall portion 21 in a range wider than the outer circumference of the screw wall portion 21, and the ridge portion is formed in the opening portion 23. 33 is engaged. And the adjacent extruded shape member 1 can be connected by screwing the screw member 4 into the screw hole 22 of the male joint part 2 from the end surface of the extruded shape member 1.

The screw member 4 is inserted into the screw hole 22 of the male joint portion 2 through the through hole 51 of the frame member 5 disposed on the end face of the extruded shape member 1. The screw member 4 is a tapping screw, and a screw groove is formed on the inner peripheral surface of the screw wall portion 21 when screwed into the screw hole 22.
The continuous extruded shape member 1 is a panel body surrounded by frame members 5 arranged on both the left and right sides, and a frame body 6 constituted by horizontal trunk edges and the like arranged at the upper and lower positions. A fence can be formed by fixing to a standing column or the like. In addition, you may fix the extruded shape material 1 provided continuously without using the frame 6 to a support | pillar etc. directly.

1A and 1B are schematic explanatory views of a connecting structure of the extruded shape member 1 of the present invention, in which FIG. 1A shows a state before the screw member 4 is screwed into the screw hole 22, and FIG. 1B shows the screw member screwed into the screw hole 22. It is the state after having done. When the screw member 4 is screwed into the screw hole 22, the protrusion 33 of the female joint portion 3 engaged with the opening 23 of the male joint portion 2 tends to be pushed outward by the screw member 4 ( In FIG. 1B, arrow (A) direction). Then, the fitting wall portion 31 also moves outward. However, since the fitting wall portion 31 is externally fitted and surrounded in a range wider than the outer circumference of the screw wall portion 21, the fitting wall portion 31 The inner peripheral surface at the tip end is crimped to the outer peripheral surface of the screw wall portion 21 (in the direction of arrow (B) in FIG. 1B), and the male joint portion 2 and the fitting joint portion 3 are firmly connected without rattling. be able to.

  In this embodiment, when the outer diameter of the screw member 4 that is a tapping screw is 4 mm, the diameter of the screw hole 22 formed by the screw wall portion 21 is formed to be smaller than the outer diameter of the screw member 4 by about 0.4 mm. The thickness of the part is set to 1 mm, and the inner peripheral diameter of the fitting wall part 31 is made larger than the outer peripheral diameter of the screw wall part 21 by about 0.3 mm. If the protruding portion 33 is made to be substantially flush with the inner peripheral surface of the screw wall portion 21 when the fitting wall portion 31 is externally fitted to the screw wall portion 21, the screw member 4 allows the protrusion of the screw wall portion 21. When the screw groove is formed on the inner peripheral surface, the protruding portion 33 receives an outward acting force to be detached from the opening 22 by the screw member 4, and the male joint portion and the female joint portion are relative to each other. The tip inner peripheral surface of the fitting wall portion 31 can be pressure-bonded to the outer peripheral surface of the screw wall portion 21.

  Further, although the ridge 33 is pushed out from the opening 22, the screw member 4 stops inside the screw wall 21, so that the ridge 33 is not completely detached from the opening 23, and the screw The end surface of the tip of the wall portion 21 and the protruding portion 33 can maintain the engaged state, and the rotation of the fitting joint portion 3 with respect to the male joint portion 2 can be prevented.

The extruded shape member 1 of the fence panel body shown in the present embodiment has holes 12 formed in the downward inclined surface 11 as shown in FIG. When a part of the wind hitting the fence panel body passes through the hole 12, the wind force can be weakened and the direction of the wind can be changed.
In addition, in the said Example, although the case where the some extruded shape member 1 was arranged in the up-down direction was demonstrated, you may continue in the left-right direction. Moreover, various shapes can be adopted as the cross-sectional shape of the extruded shape member 1, and extruded shapes having different cross-sectional shapes may be provided in series, or may be applied to other than the panel body.
