[Detailed description of the invention] The present invention relates to a hanging device for hanging a ceiling frame used for constructing a ceiling base frame, and more specifically, when installing a suspended ceiling in a building. This invention relates to a device for suspending a supporting fence from a ceiling slab, beam, etc. of a building.

When attaching a ceiling board to a building, it is necessary to attach a base frame in a suspended state to the lower surface of a concrete or wooden ceiling slab, beam, etc. in the building. Such base frames are generally divided into lightweight steel base frames and wooden base frames, and each base frame generally includes a ceiling frame to which the ceiling board is directly attached, and a frame support to support this frame. ,
It consists of a device for suspending this field support from the lower surface of a ceiling slab or the like.

A variety of field edge suspension devices have been proposed in the past, and a typical field edge suspension device currently used for construction of lightweight steel substructures will be explained with reference to Fig. 4. The base framework shown in the figure is
A ceiling edge B to which the ceiling board A is attached, and a ceiling edge support D that supports this edge B via a hook member C.
and a device E for suspending the field edge support D from the lower surface of the concrete ceiling slab S. This device E includes an insert nut F made of cast iron or plastic that is buried in the ceiling slab S when it is formed, and a hanging bolt G whose upper end is screwed into the insert nut F and extends vertically downward. , a hanger H consisting of a receiving member _h1 that supports the field edge support D, a mounting member _h2 extending horizontally from the upper end thereof, and a hanging bolt G passing through the mounting member _h2 at the lower end thereof. It is provided with a pair of nuts I, I, which are screwed together so as to be sandwiched from both upper and lower sides, thereby fixing the hanger F to the hanging bolt G. Incidentally, a joint material J is attached to the lower surface of the field edge B. In the conventional field edge hanging device E as described above, the hanger H
To attach it to the hanging bolt G, first screw the upper one of the pair of upper and lower nuts I to the lower end of the hanging bolt G, rotate it and raise it to the appropriate position, and then After fitting the mounting member _h2 of the hanger H onto the hanging bolt G through the hole (not shown) opened therein, insert the lower nut I into the lower end of this hanging bolt in the same way as the upper nut. Screw it into place and rotate it to raise it to the appropriate position. At this stage, both nuts I, I are temporarily tightened, and the hanger H is not firmly fixed to the hanging bolt G. In this state, extend the field support D between the respective support members _h1 of a plurality of hangers H (only one is shown in the figure), and then tighten the upper and lower nuts I, I on each hanging bolt G. After adjusting the horizontal level of the frame holder D by rotating it appropriately, tighten each pair of nuts I and I tightly to attach the hanger H.
firmly fix it to the hanging bolt G. As described above, according to the conventional device, two nuts I, I are required for each hanging bolt G, and the positions of these two nuts I, I are adjusted by rotating these two nuts I, I many times on the bolt G. Adjustments must be made and final tightening must be performed at the predetermined positions, which requires a lot of time and effort to operate the equipment, which is a factor that reduces the efficiency of the ceiling foundation framework construction work. I was getting used to it.

Therefore, in view of the above-mentioned circumstances, the present invention eliminates the need for a single nut to secure the hanger to the hanging bolt as in conventional devices, and therefore does not require such a nut to be rotated many times. It is an object of the present invention to provide a field edge holder hanging device which can be operated simply and easily by eliminating such troubles.

Still another object of the present invention is to provide a field edge support hanging device that allows easy adjustment, especially fine adjustment, of the hanging position of the field edge support.

A fixing member that is externally fitted to fix the locking member to a hanging bolt.

Next, an embodiment of the present invention will be described based on FIGS. 1 to 3.

In Fig. 1, reference numeral 1 indicates a suspension bolt, and a male thread 2 is formed over its entire length.
is hung down with its upper end screwed into an insert nut 3 buried in the concrete ceiling slab S and fixed thereto. 4 is a locking member engaged with the hanging bolt 1; 5 is a hanger member rotatably connected to the locking member 4; the hanger member 5 supports the field edge receiver 6; There is. 7 is a fixing member for fixing the locking member 4 to the hanging bolt 1.

As is clear from FIG. 2, the locking member 4 includes a main body 9 having a substantially U-shaped cross section and having a female thread 8 formed on the inner circumferential surface that can engage with the male thread 2 of the hanging bolt 1. It consists of a substantially semicircular locking piece 10 protruding outward from the lower end of the locking member 4.
can be formed by, for example, pressing a metal plate such as an iron plate. Also, the main body 9 of this locking member 4
are provided with retaining pieces 11, 11 on the opening side of the lower end thereof, and these retaining pieces 11, 11 make a substantially L-shaped cut in the main body 9, and pull this cut portion outward and diagonally downward. It is formed by Further, the hanger member 5 is formed by pressing a metal plate such as an iron plate, and the horizontal support wall portion 12
and a receiving part 13 which extends downward from one end of the supporting wall part 12 and is formed in a substantially U-shape so as to be able to receive the field edge support 6. The horizontal supporting wall part 12 has a central part. A circular insertion hole 14 is provided in which the main body 9 of the locking member 4 can be inserted and whose diameter is smaller than the outer diameter of the approximately semicircular locking piece 10. and receiving part 13
The inner side wall 13a extends vertically downward from one end of the horizontal support wall 12, the bottom wall 13b extends horizontally outward from the lower end of the side wall 13a, and the bottom wall 13b extends upward from the outer end of the bottom wall 13b. Inner side wall portion 13a
and an outer side wall part 13c extending substantially parallel to the outer side wall part 13c, which is formed in a slightly curved shape and whose upper end is bent outward to facilitate fitting of the field edge receiver 6. Guide section 15
The lower end portion of this guide portion 15 and the corresponding portion of the inner side wall portion 13a opposite thereto are formed to prevent the field edge receiver 6 once fitted into the receiving portion 13 from being pulled out upward. protrusion 16,1 for
7 are provided facing each other, and one protrusion 16 is formed by making a notch in the side wall portion 13c and pulling that portion inward.

As is clear from FIG. 2, the fixing member 7 is formed by pressing a metal plate such as an iron plate into a substantially D-shaped cross section, and has a U-shaped cross section corresponding to the cross-sectional shape of the main body 9 constituting the locking member 4. A U-shaped side wall portion 7a having a cross-sectional shape, and a flat side wall portion 7 having an I-shaped cross-sectional shape that closes the opening of the U-shaped side wall portion 7a.
b, and its length is appropriately shorter than the length of the main body 9 of the locking member 4. In order to fit the fixing member 7 to the main body 9 of the locking member 4, the fixing member 7 is loosely fitted to the hanging bolt 1 in advance, and the fixing member is attached to the locking member screwed onto the hanging bolt 1. It is only necessary to externally fit it into the main body 9 of the member 4 from above. Further, the radius of curvature of the inner surface of the curved portion of the U-shaped side wall portion 7a of the fixing member 7 is slightly larger than that of the outer surface of the curved portion of the U-shaped main body 9;
Thereby, the fixing member 7 can be smoothly fitted into the main body 9. Also, this fixing member 7 is the main body 9.
When fitted into the main body 9, the inner surface of the flat side wall portion 7b comes into contact with the outer surface portion of the hanging bolt 1 facing the opening of the main body 9. On the other hand, the locking member 4 and the hanger member 5 are rotatably connected to each other, and in connection, the locking member 4 is connected to the support wall of the hanger member 5 as shown in FIG. 12, and insert the main body 9 into the insertion hole 14 and push it to the lower end, so that the retaining pieces 11, 11 are elastically deformed, and the retaining pieces 11, 11 are elastically deformed as shown by the imaginary line in FIG. 2 or in FIG. With the horizontal support wall portion 12 held between the pieces 11, 11 and the hanging piece 10, the locking member 4 is rotatably and irremovably connected to the hanger member 5.

Next, to explain the use of the hanging device having the above-described structure, first, the upper end of the hanging bolt 1 is screwed into the insert nut 3 buried in the concrete ceiling slab S and fixed. The fixing member 7 is fitted into the hanging bolt 1 from below, for example, to a position as shown by the imaginary line in FIG. Then, the locking member 4 is fitted into the insertion hole 14 of the hanger member 5 in a state shown by the imaginary line in FIG.
is passed through the suspension bolt 1, the main body 9 is applied to a required part on the suspension bolt 1, the female thread 8 of the main body 9 and the male thread 2 of the suspension bolt 1 are engaged with each other, and then the fixing member 7 is lowered. , and is fitted into the main body 9 as shown by the solid line in FIG. By fitting the fixing member 7 to the main body 9 in this manner, the main body 9 is fixed in a state where it is engaged with the hanging bolt 1. Then, the field support 6 is received in the receiving portion 13 of the hanger member 5. Due to the reception of this field support 6, a downward axial load acts on the locking member 4 through the hanger member 5, but the female thread 8 of the main body 9 of the locking member 4 and the male thread 2 of the hanging bolt 1 engage with each other. Because of the fit, the hanger member 5 can be reliably held in place without slipping in the downward axial direction. Further, in this case, in particular, since the fixing member 7 is fitted over almost the entire length of the main body 9 of the locking member 4 and the cross-sectional shape of the member 7 is approximately D-shaped, the hanger member 5 is Hanging bolt 1 on the receiving part 13
Even if a load in a direction transverse to the axis of the locking member 4 is applied or some vibration is applied, the locking member 4 itself will not rotate or wobble at all.
It is possible to maintain a state of engagement with the suspension bolt 1 and to securely fix it to the bolt 1.

In addition, in order to change the hanging height of the field edge support 6 from the ceiling slab S as necessary, the hanger member 5
When adjusting the fixing position on the hanging bolt 1, especially when making a large adjustment, slide the fixing member 7 upward with respect to the locking member 4 to the position shown by the imaginary line in FIG. By pulling up the locking member 4, the locking member 4 is released from the restraint by the fixing member 7 and becomes free.
The position can be arbitrarily adjusted by sliding the suspension bolt 1 in the axial direction along the suspension bolt 1 while being appropriately separated from the outer circumferential surface of the suspension bolt 1. On the other hand, when making fine adjustments, if the fixing member 7 fitted to the main body 9 of the locking member 4 is rotated as it is, the locking member 4 rotates together with the fixing member 7, and the hanging bolt 1 According to the vertical movement of the locking member 4, the hanger member 5 can be moved vertically little by little.

Note that the entrance of the receiving part 13 is formed narrow in advance as shown by the imaginary line in FIG. By slightly expanding outward due to deformation, the field edge receiver 6 can be fixed without wobbling when fitted.

As explained above, according to the present invention, the hanger member can be easily attached to any position on the hanging bolt, and once the hanger member is attached and the field support is inserted, the position will not shift due to vibration or impact. , it is possible to reliably support the Noen Uke. That is, when installing the hanger member, the locking member having a substantially U-shaped cross section is inserted into the insertion hole of the hanger member, and the locking member is pressed against the hanging bolt from the outside. The fixing member only needs to be fitted from above, and to remove it, the fixing member can be pulled out from the locking member, so the attachment and detachment of the hanger member is extremely easy and quick compared to conventional devices. I can do it. Since the locking member is rotatable with respect to the hanger member, if the locking member is rotated, the hanger member can move up and down without rotating. This is particularly effective when finely adjusting the hanging height of the field fence with the fence installed. As described above, according to the hanging device of the present invention, construction of the ceiling base can be performed easily and quickly.
