Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fixing a bar member used for cross-fixing an upper bar member to a lower bar member, like a bar member for holding a fire extinguisher pipe installed and fixed to a bar member of a ceiling base frame. For anti-slip metal fittings.

[0002]

2. Description of the Related Art This type of bar member fixing anti-vibration fitting is, for example, a horizontal projection at the upper end projecting in one direction, a bar material engaging part at the lower end, and a pair of widthwise opposing members for connecting them. A single metal fitting member having a downward opening disposed between walls and having a screw hole formed in the horizontal projection and having a single U-shape, and a tightening bolt screwed into the screw hole. , The bar member engaging portion is for engaging the upper and lower bar members at the upper end, and the fastening bolt is for pushing down and pressing the upper bar member of the upper and lower intersecting bar members which are arranged through the opening. , When the bar material for holding the fire extinguishing water pipe is erected and fixed to the bar material of the ceiling base frame, for example, the lower bar material is a C-shaped channel material,
The upper bar material is supposed to use a square or C-shaped channel material.

[0003]

In this case, since the metal fitting member is a single member, there is an advantage that the anti-vibration metal fitting can be made inexpensive and easily fixed. There is a possibility that the bar fixing function as the vibration-proof metal fitting may be impaired or lost due to detachment or further drop.

That is, the relationship between the metal fitting member and the upper and lower cross bar members is such that the upper bar member penetrates the opening when the upper bar member of the tightening bolt is pushed down and the upper bar member penetrates the opening. Since the bar member engaging portion engages with the upper end of the bar member in the lower bar member such as the C-shaped channel member, the bar member engaging portion is engaged with the horizontal fin-shaped ridge. Therefore, even if the upper bar material does not come off first, if external force is applied to the metal member or the upper and lower bar materials exhibit different horizontal movements, If the bar member engaging portion cannot maintain the hooking engagement state, the metal fitting member may eventually come off from the lower bar material and come off, or even fall off. The material fixing function is impaired or lost. Over material leads to a non-fixed state.

Particularly, after fixing the bar member using this kind of anti-vibration fitting, there are cases where other works and works such as electric wiring work and maintenance inspection after installation of the fire extinguishing water pipe are carried out. An external force may be applied to the body by the worker's body or foot touching the anti-vibration metal, and when an earthquake occurs, the upper and lower bar materials move horizontally differently due to the vibration of the building. ， There is a possibility of rocking between the upper and lower bar materials and position shift due to this,
In such a case, it is expected that the bar fixing function of the anti-vibration fitting will be directly affected.

The present invention has been made in view of the above circumstances, and a problem to be solved by the present invention is that the bar member can be fixed as easily as possible, and the bar member can be reliably removed for a long period without the possibility of coming off. (EN) It is an object to provide a bar stop fixing metal fitting for maintaining and securing a fixing of a bar material.

The short metal fitting member 2 has a width of 5 cm and a height of about 3 cm, and is integrally formed as a piece of steel fitting.

At this time, the overlapping projections 3 at the upper end are formed by rectangular plate-shaped horizontal projections formed by horizontally bending the respective upper ends in the opposite direction, and the width of the projections is a short metal fitting. By setting the length on the member 2 side to be slightly longer, stability is ensured when they are polymerized with each other, and these polymerized projections 3 are pierced in the vertical direction by burring or punching. In the long metal fitting member 1 having a female thread, for example, a screw hole 4 having a diameter of 5 mm is formed, and in the short metal fitting member 2, a through hole 5 having a diameter larger than the screw hole 4, for example, 8 mm is transparent. As a result, the above-mentioned overlapping protrusion 3 is provided.
When overlapping and using as the vibration-proof metal fitting A, the overlapping projection 3 on the short metal fitting member 2 side is held loosely in the tightening bolt 12, and the short metal fitting member 1 is short. This is to ensure the flexibility of tilting and expanding the fitting member 2.

Further, the bar member engaging portion 6 at the lower end is formed by projecting by horizontally bending the lower ends of the pair of leg walls 8 respectively hanging below the overlapping projections 3 in the same direction. On the metal fitting member 2 side, a rectangular small piece plate-shaped horizontal projecting piece is used, and on the long metal fitting member 1 side, the projecting width is set to be slightly longer, and the projecting tip has a low standing wall 7 folded back upward. The flat rectangular small piece forming the upward receiving groove is formed by a horizontal L-shaped projecting piece having an inverted L-shaped side surface, whereby the bar member engaging portion 6 of the short metal fitting member 2 is for hook engagement, The bar member engaging portion 6 of the long metal member 1 is adapted for holding and engaging.

The downward opening 9 is opened downward with the upper end position aligned and the lower end opened by a notch formed between the pair of widthwise leg walls 8 below the overlapping projection 3 to form the leg wall 8. It is assumed that the opening dimension in the width direction is set to be slightly wider than the width of the upper bar material 20 as a reference. In this example, the reference upper bar material 20 is used.
Has a width of 16 mm, and the long metal fitting member 1 has a width of 19 mm, while the short metal fitting member 2 has a width of 22.5 mm, which is wider than the 19 mm. Although this is based on the width of the upper bar material 20, the through bar arrangement of the upper bar material 20 is facilitated, while the through-arranged upper bar material 20 has a variable angle, particularly on the short metal fitting member 2 side, The crossing angle with respect to the lower bar member 21 is adjustable.

The tightening bolt 12 used in this embodiment is a butterfly bolt which has a butterfly-shaped groove at the top to facilitate the tightening operation with a fingertip. , A pair of long and short metal fittings 1 and 2 are arranged so as to face each other, and the short metal fitting 2 side having the through hole 5 is the upper side and the long metal fitting 1 side having the screw hole 4 is the lower side. Polymerize part 3,
Through the through hole 5 having the large diameter, the screw member 4 is screwed into the screw hole 4 on the long metal fitting member 1 side so as to be capable of projecting and retracting downward.
It forms a tightening means for fixing the tightening.

The spring washer 13 is, for example, 1 mm vertically between the overlapping protrusions 3 thus overlapped.
To a few millimeters width, which is made to give elasticity by spring force, is interposed between the overlapping protrusions 3, and thereby the above-mentioned overlapping protrusions 3 are overlapped. A short metal fitting member to a long metal fitting member 1 by avoiding direct interviews, using the spring washer 13 as a spacer to secure a space between the overlapping projections 3, and making the through hole 5 larger in diameter than the screw hole 4. 2 is designed to be able to secure greater flexibility in the inclination and expansion, and when the tightening bolt 12 is tightened, the long metal fitting member 1
When the overlapping projection 3 of the short metal fitting member 2 is elastically floated and separated from the overlapping projection 3 of the above, and the short metal fitting member 2 is used for projecting and fixing as described later, It is intended to provide elasticity for thrusting.

In the bar material fixing using the vibration-damping metal fitting A having the above-described structure, the upper bar material 20 of the upper and lower bar materials 20 and 21 intersecting the upper and lower bar materials 20 and 21 are penetrated through the openings 9 of the long and short metal fitting members 1, 2. The bar member engaging portion 6 of the long metal member 1 engages with the lower end of the lower bar member 21 of the upper and lower bar members, and the lower bar member engages the bar member engaging portion 6 of the short metal member 2. The upper end of the material 21 is hooked and engaged, and the upper bar material 20 penetratingly arranged is pushed down and pressed by the tightening bolts 12, whereby the long and short metal fittings 1 and 2 The member 2 is the upper and lower bar members 20, 21
In this case, the bar member is fixed for fixing the bulge and for fixing the other long metal fitting member 1 to prevent it from coming off.

That is, in the swing stop fitting A, when fixing the lower bar member 21 and the upper bar member 20 placed on the lower bar member 21 so as to intersect with each other, the upper bar member 20 is opposed to the upper bar member 20. While penetrating through the openings 9 of the pair of long and short metal fitting members 1 and 2, the lower bar material 21 is held on both sides so as to be sandwiched by the long and short metal fitting members 1 and 2, and the bar material engaging portions 6 are The lower bar member 21 is engaged, and the long and short metal member 1, 2 are integrated by the tightening bolt 12 from the overlapped projection 3 of the long and short metal member 1, 2 and the upper bar member 20 is pressed. The long and short metal fitting members 1, 2
The overlapping projection 3 of FIG. 2 has the short metal fitting member 2 side as the upper side and the long metal fitting member 1 side as the lower side, and the tightening bolt 12 is screwed into the screw hole 4 of the lower long metal fitting member 1. The upper bar member 20 is pressed to raise the overlapping projection 3 of the short metal fitting member 2 upward, while the bar material engaging portions 6 of the long and short metal fitting members 1 and 2 are the same as those of the long metal fitting member 1. , The bar-engaging portion 6 for hug-engaging is hug-engaged with the lower end of the lower bar member 21,
In the short metal member 2, the bar member engaging portion 6 for hooking engages with the upper end of the lower bar member 21. Therefore, by tightening the tightening bolt 12, the short metal member 2 becomes long. A force in the projecting direction is to be received between the overlapping projection 3 of the metal fitting member 1 and the bar material engaging portion 6 hooked and engaged with the lower bar material 21 by which the long metal fitting member 1 is held and engaged. , The short metal fitting member 2 is a member for fixing the above-mentioned bulge, and is a lower bar member 2
1 and the upper bar member 20 which is placed crosswise thereto are fixed by tightening the tightening bolts 12, and at this time, the spring washer 13 causes the long and short metal fittings 1, 2.
It is located between the overlapping protrusions 3 of 2 and exhibits resilience that vertically repels between the overlapping protrusions 3 when the tightening bolt 12 is tightened.
The force in the thrust direction is elastically strengthened, and the fixation is further ensured.

On the other hand, the long metal fitting member 1 faces the short metal fitting member 2 on the opposite side of the lower bar material 21 from the lower bar material 2.
Since the lower end of 1 is held and engaged, even if an external force is applied to the vibration-proof metal fitting A or the upper and lower bar members 20 and 21 move horizontally differently due to an earthquake or the like, the lower bar member 21 and The above-mentioned fixation by the short metal fitting member 2 is maintained by maintaining the engagement relationship of the above and by integrating with the tightening bolt 12 at the overlapping projection 3 at the upper end thereof, and therefore the long metal fitting member 1 is shaken. The stopper A serves as a stopper member that protects the fixing by the short metal member 2 from an external force.

Therefore, as shown in the figure, the lower bar member 21 of the ceiling base frame is, for example, attached by the swing stop fitting A.
When the upper bar member 20 for holding the fire extinguishing water pipe 23 is erected and fixed, the lower bar member 21 is a C-shaped channel member, and the upper bar member 20 is a J-shaped channel member. Even if the bar member engaging portion 6 of the member 2 is engaged with the horizontal fin-shaped ridge 22 of the lower bar member 21, the fixing can be ensured for a long period of time and is strong against external force. In addition, it is earthquake resistant and will not come off.

Further, in order to fix the bar member with the anti-vibration metal fitting A, the tightening bolt 12 is screwed into the screw hole 4 through the through hole 5, and the short metal fitting member 2 and the long metal fitting member 1 are attached. After expanding and inclining with respect to each other, the upper and lower bar members 20 and 21 are hooked in such a manner that they are swallowed, and each bar member engaging portion 6 is engaged with the lower bar member 21. , Tightening bolt 12
Can be tightened with a fingertip, and the fixing work can be performed very easily. Moreover, the crossing angle of the upper bar member 20 is changed as necessary depending on the opening size of the opening 9, and the adjustment is performed. It becomes possible to do.

In the figure, 10 is the opening 9 of the short metal fitting member 2.
Provided on both sides of, for example, when using U-shaped channel material,
Fitting protrusions that fit into the openings of the upper bar member 20 and prevent deformation due to tightening of the tightening bolts 12, 11 is a reinforcing rib provided on each of the long and short metal fitting members 1 and 2, and 24 is the upper bar member 20. Is a swing stop fitting for fixing the fire extinguishing water supply pipe 23.

Although the illustrated example is as described above, the through hole of the short metal member is made a long hole in the facing direction of the long metal member,
As a result, if the tightening bolt is loosely fitted and has a large diameter as described above, the flexibility of the inclination expansion of the short metal member is secured in the same manner. It is used for hooking the lower end of the material, and is mainly intended to prevent disengagement by sandwiching and holding both sides of the lower bar material in the long and short metal fitting member. Instead of the spring washer, for example, a coil spring or a piece made of rubber or synthetic resin. Long metal fittings, short metal fittings, and tightening bolts, including the use of elastic materials that act as spacers, such as elastic cushioning materials for members, and that provide elasticity between polymerized materials , Specific shapes, structures, materials, dimensions of spring washers or elastic members instead of spring washers, their relations, addition to these, use as anti-vibration fittings, etc. , Unless contrary to the gist of the invention, it is possible to change its form.

[0022]

The present invention is configured as described above.
By using a pair of metal fittings, which are a pair of opposite side U-shaped long and short, the upper bar material penetrates through the openings of these metal fittings, while the lower bar material is sandwiched by both long and short metal fittings. With both sides held, the respective bar member engaging portions are engaged with the lower bar member, and the long and short metal fitting members are integrated by the tightening bolts from the overlapping portion of both metal fitting members. Also, by pressing the upper bar member, one of the long and short metal fitting members is used as a member for fixing the upper and lower bar members to the bulge and the other long metal member is a member for preventing the detachment thereof. Therefore, by inclining and expanding the short metal fittings at the intersections of the upper and lower bar members and hooking them to tighten the tightening bolts, the bar members can be fixed as easily as possible and the possibility of detachment is increased. Without long term It is possible to provide a stop member vibration bar material fixedly capable of reliably maintaining a fixed bar member secured.
