[Detailed description of the device]

[0001]

[Industrial application] This invention is for connecting a spherical joint to a roof panel sash when a roof panel such as glass is attached to the roof of a space truss type building using a spherical joint with the roof panel sash. Regarding fasteners used.

2. Description of the Related Art A three-dimensional truss type building is, for example, as shown in FIG. 5, a three-dimensional space formed by a base frame F by a three-dimensional truss such as an octaplate structure using a spherical joint G. It is often used for buildings called atriums or canopies that take daylight into consideration.

Therefore, the outer periphery of the base frame F, that is, the roof and the side walls are generally covered with a roof panel P made of a transparent material such as glass, and correspond to the frame grid Fg formed on the base frame F. The roof panel sash S is used in combination so as to form a rectangular sash grid Sg, and the roof panel P is attached.

The roof panel sash S is attached to the spherical joint G by using a fastener (mounting metal fitting), and a typical fastener has a structure as shown in FIG.

The fastener 100 comprises a rod portion 101 and a support plate portion 102, and the rod portion 10
The male screw portion 103 formed at the base end of 1 is connected to the spherical joint G
While being connected to the spherical joint G by being screwed into the female screw formed in the above, it is bolted to the roof panel sash S through the insertion holes 104 formed in the supporting plate portion 102. ing.

Although such a fastener has been used for many years, it cannot be said to be sufficient because it has a number of problems. That is, since a space for rotating the support plate portion when screwing into the spherical joint is required,
It is necessary to carefully check the surrounding conditions so that there is no restriction on the procedure of connection to the spherical joint or there is no obstacle to rotation; there may be variations in the welding of the rod part and the support plate part. Therefore, it is inferior in quality stability; it is necessary to prepare rods of different sizes depending on the distance between the spherical joint and the roof panel sash, that is, it is necessary to calculate and prepare the number of rods of various sizes in advance. If the support plate does not fit the roof panel sash and you try to force it to fit, the amount of screwing the rod part into the spherical joint will be adjusted and the direction of the support plate will be adjusted to the roof panel sash. Since it will be aligned with the direction, the required amount of screwing cannot be secured and the rod part will not be fully screwed into the spherical joint.
There are problems such as.

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a fastener which can solve various problems in the conventional fastener.

[0008]

SUMMARY OF THE INVENTION A fastener according to the present invention comprises a bolt member having a male screw threaded to a female thread formed on a spherical joint, and a recessed portion for receiving a bolt head of the bolt member at a central portion. A central part insertion hole for inserting a bolt member is formed in this recess, and side surface insertion holes for inserting bolts when bolting to the roof panel sash are formed in flat parts on both sides of the recess, respectively. And a plate member that is formed.

In order to attach the roof panel sash to the spherical joint by using this fastener, the bolt member is freely inserted into the through hole of the plate member,
First, the bolt member is turned with an appropriate wrench to be screwed into the spherical joint, and then the plate member is fixed to the roof panel sash. The bolt member and the plate member are fixed to each other by tightening with a nut that is set on the bolt member in advance, or by tightening the plate member to the spherical joint with the bolt member itself, and the former tightening is appropriate. You can follow the procedure.

That is, this fastener is in a separated state in which both the plate and bolt members are not regulated by each other, and therefore the bolt member is connected to the spherical joint and the plate member is connected to the roof panel sash separately. You can For this reason, since it is not necessary to rotate the plate member which is particularly long in the lateral direction and is easily influenced by the surroundings, it is less restricted by other members in the surroundings, and thus various types of fasteners such as those described above are used. The problem of can be solved. Further, since it is not necessary to use welding for fixing the bolt member and the plate member to each other, the quality stability is improved.

[0011]

Embodiments of the present invention will be described below. The fastener 1 according to the present invention comprises a plate member 2 and a bolt member 3, as shown in FIGS.

The plate member 2 has flat portions 4 and 4 on both sides and a concave portion 5 between the flat portions 4 and 4. The plate member 2 is made of an aluminum long molding with a predetermined width. It is formed by cutting into.

The flat portion 4 is a portion for mounting and supporting the roof panel sash S, and a side portion insertion hole 6 through which the mounting bolt B is inserted is formed. Further, the recess 5 is a portion for receiving the bolt head 3h of the bolt member 3 so as not to project above the flat portion 4, and a central portion insertion hole 7 for inserting the bolt member 3 is formed.

As the bolt member 3, a galvanized bolt commercially available as a standard product is used. The bolt member 3 has a length corresponding to the distance between the spherical joint G and the roof panel sash S. When the distance is wide and long as in the case of FIG. 1, a nut 8 is used to plate the plate member 2. And the nut 9 is used to tighten the bolt member 3 to the spherical joint G, and when the gap is narrow and short as in the case of FIG. 3, the plate member 2 is tightened to the spherical joint G by the bolt member 3 itself. It will be.

As described above, the fastener according to the present invention comprises the plate member and the bolt member which are separated from each other, and connects the bolt member to the spherical joint and the plate member to the roof panel sash mutually. Since it can be done without being restricted by the members of
It has the following effects. When connecting to the spherical joint, all you have to do is rotate the bolt member, so a space for operating the appropriate wrench will suffice, and the procedure for connecting to the spherical joint will be free, depending on the surrounding conditions. There are few restrictions and workability is improved. Since it is easy to obtain uniformity in the fixing force between the bolt member and the plate member, quality stability can be obtained. Since a commercially available standard bolt can be used as the bolt member, it is easy to deal with the size change. Since the plate member and the bolt member can be fixed separately, and it is not necessary to adjust the amount of screwing the bolt member into the spherical joint when adjusting the direction of the plate member to the roof panel sash, screwing the bolt member into the spherical joint. Can always be secured to the required range, so that a reliable fixing can always be performed. The plate member can be formed by cutting a long aluminum molded material into a predetermined width by using a commercially available standard plated bolt as the bolt member, so it is easy to manufacture and stable quality is obtained. To be
