Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a column/horizontal member joining device for horizontally attaching a horizontal member to a vertically erected column.

[Prior Art] A device shown in FIG. 8 is conventionally known as a device for joining column members and horizontal members.

According to this prior art, a plurality of screw holes 24 are provided in the left and right sleeve plates 23 of a U-shaped support 22 fixed to one side of a column 21, and a plurality of screw holes 24 are provided on the outside of the support 22 at the side ends of a horizontal member 25. The column members 21 and the horizontal members 25 are joined when they are engaged and the insertion holes 26 provided in the horizontal members are aligned with the screw holes 24 and the screws 27 are inserted.

[Problems to be solved by the invention] The above-mentioned conventional technology has the disadvantage that the head of the screw 27 inserted from the outside of the horizontal member 25 is visible from the outside, making it unsightly, and It takes a lot of time and effort to match the screw holes 24 and insertion holes 26 of the horizontal member, which reduces work efficiency. Also, if the screw holes 24 and insertion holes 26 are formed in a discrepancy, they will not match and it will be difficult to insert the screws. It has the disadvantage of being difficult to insert.

In addition to these disadvantages, since the horizontal members 25 are installed horizontally as shown by the arrows, for example, when assembling multiple horizontal members in a ladder shape, both pillars are erected in advance and the distance between them is fixed. There is also the problem that if the horizontal members are fixed, it becomes impossible to intervene with the horizontal members.

[Means for Solving the Problems] The present invention has been made in view of the prior art, and a receiver 2 with hooks 3 formed on the left and right ends is fixed to one side of a column 1. In the window hole 9 in the front of the fixing metal 8 provided on the inner side near the end of the horizontal member 7 facing the
A U-shaped bending metal 10 having a hook portion 11 at its tip that engages with the hook piece 3 of the receiving metal is attached, and a pressing metal 13 is provided at the inner rear part of the bending metal 10 to press the bending metal backward. In addition, it is an object of the present invention to provide a joining device for a column and a horizontal member in which the above-mentioned disadvantages are eliminated by the rotor 16 for operating the presser metal 13 being located in the through hole 18 in the lower surface of the horizontal member 7. I'm expecting.

[Function] In order to join the horizontal member 7 to the column member 1, first, the bending metal 10 is lowered from the upper surface of the support metal 2 with the tip thereof protruding slightly more than the horizontal member 7. Then, the hook portions 11 at the tips of the bent metal fittings engage with the hook pieces 3 on the left and right sides of the receiving plate, and the horizontal member 7 is positioned. Therefore, when the rotator 16 is turned using a driver (not shown) from the lower surface of the horizontal member, the presser metal 13 moves and presses the bent metal piece 10 backward, so that the bent metal piece 10 that has been pressed moves backward. The hook portion 11 at the tip is firmly connected to the hook piece 3 of the receiver 2, and the end portion of the horizontal member 7 is closely connected to the column member 1, making it immovable.

[Example] What is shown in FIGS. 1 to 4 is the first example of the present invention.
In this embodiment, 1 is a square pipe-shaped pillar, and 2 is a receiver fixed to the pillar. The receiver 2 has inward hook pieces 3 at its left and right ends and a support piece 4 at its lower end, and a screw 6 is inserted through a base piece 5 that abuts the column 1 to screw it onto the column. Reference numeral 7 is a square pipe-shaped horizontal member facing horizontally to the pillar 1, and a fixed metal plate 8 with a planar inverted U-shape is provided closely on the inner side near the end, and a window hole 9 is bored in the front side of the fixed plate. A flat U-shaped bent metal 10
is installed. At both ends of the bending metal 10 protruding from the window hole 9, outward-facing hooks 11 are formed that match the hooks 3 of the receiving metal. As shown in Figure 1, it protrudes a little further than the end of the horizontal member, but after engagement, it sinks into the inner side of the horizontal member as shown in Figure 2, and also facilitates the engagement of the receiver 2 and the bending member 10. In order to do this, a small notch 12 is formed on the lower surface of the end of the horizontal member 7.

Reference numeral 13 denotes a pair of upper and lower rectangular pressing metals provided inside the bending metal 10, the rear ends of which are formed with an inclination.
It is in contact with the inside of the rear surface at 0, and the upper gold plate 13a
A screw hole 14 is formed in the lower metal member 13b, and an insertion hole 15 is formed in the lower metal member 13b, and a screw shaft 17 having a rotator 16 at the lower end is attached to the screw hole 14 and the insertion hole 15. That is, the lower part of the screw shaft 17 is loosely inserted into the insertion hole 15, and the upper part is screwed into the screw hole 14,
Further, the upper surface of the rotor 16 at the lower end is in contact with the lower metal member 13b, and the rotor 16 is located at a position that coincides with a through hole 18 formed in the lower surface of the horizontal member 7 so as to be operated by a screwdriver.

Place the above-mentioned horizontal member 7 on the pillar material 1 and
When descending from the upper end, the hook portion 11 of the bending metal 10 engages with the hook piece 3, and the lower end hits the support piece 4, so that the horizontal member 7 is positioned. Therefore, when the rotor 16 is moved by a screwdriver, the screw shaft 17 rotates and screws inside the screw hole 14 of the upper metal 13a of the presser metal, and the upper metal 1
3a descends along the screw shaft 17, so that the inner side of the rear surface of the bent metal 10 is pressed against the rear end of the upper metal metal, which is formed at an angle. Moreover, the rotor 16 has a screw shaft 17
At the same time, the lower metal 13b that is in contact with the rotor also rises, and the rear surface of the bent metal 10 is pressed against the raised rear end of the lower metal 13b. In other words, when the rotator 16 is operated, the presser metal 13 presses the bending metal member 10 and causes it to retreat, and as a result, the hook portion 11 is firmly engaged with the hook piece 3, so that the horizontal member 7 is immovable with the column member 1. It is joined in a shape.

5 to 7 show a second embodiment of the present invention, in which tongue pieces 8a and 8b are formed at the upper and lower ends of the fixing metal 8 attached to the horizontal member 7, respectively.
Eccentric protrusions 13a and 13b protruding from the upper and lower ends of the cylindrical presser 13 intervene in the oval holes H formed in the tongue pieces 8a and 8b, and the rotor 16 provided on the lower protrusion 13b acts as a driver. It is located in a through hole 18 drilled in the lower surface of the horizontal member 7 so that it can be operated.

In this embodiment, as in the first embodiment, when the horizontal member 7 is applied to the column member 1 and lowered from the upper end of the support 2, the hook portion 11 of the bending member 10 engages with the hook piece 3, and the lower end is supported. The horizontal member 7 is positioned by hitting the piece 4. Next, when the rotator 16 is moved with a screwdriver, the eccentric protrusions 13a and 13b rotate, and the presser metal 13
acts like a cam, and the inner side of the rear surface of the bent metal 10 is pressed. That is, when the rotator 16 is operated, the presser metal 13 presses against the rear surface of the bending metal member 10 and moves it backward, and as a result, the hook portion 11 is firmly connected to the hook piece 3, so that the horizontal member 7 is connected to the column member 1. There is no difference from the first embodiment in that they are immovably joined.

In addition, although the case where the receiving plate 2 in the above-mentioned embodiment is fixed to the column material 1 with screws is illustrated, if the receiving plate is formed integrally with the column material and is made into a long object, the horizontal member can be attached to any part of the column material. In addition, when the hook 3 of the receiving metal is formed outward, the two can be joined by forming the bent metal hook 11 inward. This invention belongs to the free practice of this invention.

[Effect of the idea] The present invention has the following unique effects.

(1) No screws are used directly to connect the column and horizontal members, and the rotator, which is operated by a screwdriver, etc., is located on the bottom of the horizontal members, so it is not visible from the outside and is therefore aesthetically pleasing. It looks good without compromising the look.

(2) Since the horizontal members are installed by lowering them from the upper end of the supports, they can be easily intervened even if the two pillars are already erected. There is no difficulty in assembling it.

(3) Since the receiving plate and the bending plate are aligned vertically, they can be engaged very smoothly, and the bending plate can be fixed by simply turning the rotator and pressing the presser metal, which is a hassle-free operation. Good efficiency.
