Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is for suspending ceilings, electricity, piping and other equipment from ceiling hanging metal fittings, especially deck plates used for construction of synthetic floor slabs, etc. The present invention relates to a suitable ceiling hanging metal fitting.

(Prior Art) Conventionally, in order to construct a suspended ceiling on a deck plate, as shown in FIG. 6, between the concave portions 3 formed in the lower longitudinal direction of the inclined web 2 of the deck plate 1, as shown in FIG. As shown in FIG. 6, a laterally long bent metal fitting 4 which is bent (or curved) is pushed in by a bolt 5 connected to the central part so that it can be screwed up and down vertically, and both ends of the metal fitting 4 are recessed. It is fitted and locked in 3,3, and the field edge receiver 6 of the ceiling base is supported on the lower end of the bolt 5, the field edge 7 is attached to the field edge receiver 6, and the ceiling board 8 is laid against the field edge 7. . (See Japanese Patent Laid-Open No. 63-5115) (Problems to be solved by the invention) By the way, the horizontally long stopper 4 shown in FIG. 7 used for the construction of the above suspended ceiling is provided between the recesses 3 and 3. Since it is pushed in, it must have flexibility (elasticity). When the plate pressure is made thin in order to have flexibility (elasticity), when the ceiling member is suspended and held, the weight of the ceiling member causes the fastener 4 to reversely bend, which in turn causes the fastener 4 to fall between the recesses 3 and 3. There is a risk that the ceiling member will fall off from it. Therefore, the fastener 4 must be thick enough to hold the ceiling member. As a result, the flexibility (elasticity) becomes poor, and it becomes difficult to press into the recesses 3, 3. Further, since the bolt 5 only fixes the upper end, it is weak against shaking and cannot stably suspend and hold the ceiling member.

Therefore, when the suspended ceiling is constructed on a deck plate or the like in which locking steps or grooves are formed in the lower longitudinal direction of the inclined web, the present invention provides a simple structure between the locking steps and grooves of the inclined web. An object of the present invention is to provide a ceiling hanging metal fitting that can be securely pushed and locked to safely suspend and hold a ceiling member and the like.

(Means for Solving the Problems) A ceiling hanging metal fitting such as a deck plate of the present invention for solving the above problems is a trapezoidal plate that is bent symmetrically from the upper side to the left and right sides and to the lower side, and the end portion of the lower side. The locking metal fittings are formed by stacking one another and bending it with elasticity in the width direction. A slot is formed in the width direction in the overlapping part of the lower side of the locking metal fittings. The bolt is passed through the long hole of and the upper side is screwed.

(Operation) The ceiling hanging metal fitting of the deck plate of the present invention configured as described above is to be pushed and locked between locking step portions or grooves formed in the lower longitudinal direction of the inclined web of the deck plate, Holding the bolt and pushing the locking metal fitting into the lower recess of the corrugated ridge, the inclined left and right sides are pressed against the inclined web,
It bends inwardly against its own spring force, and the lower sides that overlap with this slide inwardly along the bolts that penetrated the long holes and enter the recess while narrowing the width dimension. breath,
When the locking step or groove formed in the lower longitudinal direction of the left and right slant webs is entered, both left and right sides are released from the pressure of the slant web, and are spread outward by both sides by their own spring force. Therefore, the lower side overlapping portion also slides left and right, and stops with the bolt held in the center of the locking metal fitting. In addition, when the ceiling sill is supported on the lower end of the bolt, the field is attached to the sill, and the ceiling is laid against the sill, the ceiling hanging metal fitting of the present invention is more weighted by the weight of the ceiling member on both left and right sides Although it tries to spread outward, the ends of the long holes of the overlapping part pull the bolts from both sides, and the truss structure is formed by the left and right sides of the locking metal fittings and the bolts, never coming off, so it is safe and secure. The ceiling member is suspended and held in the. Moreover, since the bolt can be held at the center with respect to the trapezoidal plate, it is strong against shaking and can stably suspend and hold the ceiling member.

(Embodiment) The first embodiment of the ceiling hanging metal fitting of the deck plate of the present invention
Explaining it with the figures, the plate 10 is bent in a trapezoidal shape from the upper side 11 to the left and right side sides 12, 12 'and the lower sides 13, 13' in a symmetrical manner, and the lower sides 13, 13 'are superposed in the middle so as to have elasticity in the width direction. The holding metal fitting 14 was formed so as to be held and bent. A bolt insertion hole 15 is provided at the center of the upper side 11 of the locking metal fitting 14.
On the upper side 11 and the nut concentric with the bolt insertion hole 15.
16 was fixed by welding, and elongated holes 17 and 17 'were provided in the width direction at the center of the overlapping portions of the lower sides 13 and 13'. And the bottom edge 13,
A bolt 18 is penetrated from below into the elongated holes 17 and 17 'of the 13', and is screwed into the nut 16 through the bolt insertion hole 15 of the upper side 11.

As shown in FIG. 2, the ceiling hanging metal fitting 20 of the deck plate of the embodiment configured as described above is press-fitted between the locking step portions 23 formed in the lower longitudinal direction of the inclined web 22 of the deck plate 21. In order to grasp
When pushed into the recess 25 on the lower side of 24, the slanted left and right sides 1
2,12 'are pressed by the inclined web 22 and bend inwardly against the spring force against themselves, and the lower side 13,13' polymerized with this
Slide inwardly along the bolts 18 penetrating the long holes 17, 17 'and enter the recess 25 while narrowing in the width direction, and are formed in the lower longitudinal direction of the left and right inclined webs 22. When entering the locked stepped portion 23, the left and right sides 12, 12 'are released from the pressure of the inclined web 22 as shown in FIG. 3, and the left and right sides 12, 12' are moved outward by their own spring force. The bolt 18 extends toward the left side, and the bolt 18 is restrained by the ends of the elongated holes 17 and 17 'of the lower side 13 and 13' of the locking metal fitting 14, and the bent portions 12a and 12b of the lower ends of the left and right side edges 12 and 12 'have an acute angle. 12a 'is locked to the locking step portion 23. As a result, the locking fitting 14 has a truss structure together with the bolt 18.

Therefore, by laying the ceiling edge field support 6 at the lower end of the bolt 18, the left and right sides 12, 12 'of the trapezoidal locking metal fitting 14 of the ceiling hanging metal fitting 20 are further spread outward by the weight of the ceiling member. Even if the bolt 18 is tried, the bolt 18 is restrained by the ends of the long holes 17, 17 'of the lower sides 13, 13' of the locking metal fitting 14 and never comes off, so that the ceiling member is suspended and held safely and securely. Moreover, since the bolt 18 can be held at the center by screwing the trapezoidal locking metal fitting 14 into the nut 16 and restraining it by the elongated holes 17 and 17 ', it is strong against shaking and stably suspends the ceiling member. Can hold

In addition, the upper side of the locking metal fitting 14 of the ceiling hanging metal fitting 20 of the present invention
The nut 16 for screwing the bolt 18 on the upper side 11 may be provided on the lower surface of the upper side 11 as shown in FIG. Alternatively, the nut 16 may be omitted, and a screw hole 15 'may be directly formed in the upper side 11 as shown in FIG. 5, and the bolt 18 may be screwed into the screw hole 15'.

(Effects of the Invention) As can be seen from the above description, the ceiling hanging metal fittings such as the deck plate of the present invention are provided with the suspended ceiling or the like on the deck plate having the locking step or groove formed in the lower longitudinal direction of the inclined web. At the time of construction, by grasping the bolts and pushing the trapezoidal locking metal fittings into the recesses on the lower side of the ridges of the corrugation of the deck plate, etc. Since the ceiling member is easily and surely pushed and locked in the groove, if the ceiling member is attached to the lower end of the bolt, the ceiling member can be safely and reliably suspended and held. Moreover, since the bolt can be held at the center by screwing the trapezoidal locking metal fitting to the upper side and restraining it by the elongated hole at the lower side, the bolt is strong against shaking and the ceiling member can be stably suspended and held. Further, in the trapezoidal locking metal fitting, even if it does not have a spring force, when the bolt is loaded, the left and right sides expand outward, so that the acute bent portion at the lower end is locked by the locking step. . Therefore, the ceiling member can be held safely and reliably.

Further, if the bolts are restrained at the ends of the two elongated holes on the lower side of the locking fitting, the locking fitting has a truss structure and can be held more reliably.
