Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deck plate improved so that a hanger for suspending a ceiling or the like can be attached to a lower surface of a deck plate mainly used for construction of a reinforced concrete floor slab.

[0002]

[Prior Art]

 Conventionally, in order to suspend the ceiling hanging metal fitting on the flat deck plate 1 as shown in FIG. 4, it is considered that a hole is made in the flat portion of the deck plate 1 and an insert stud is used. In addition, a hanger is attached to the leg 2 having a hollow triangular cross section on the lower surface of the deck plate 1 (Japanese Utility Model Publications 2-8965 and 2-10175 are known as prior art documents).

By the way, in the former method using the insert stud, it is necessary to drive the insert stud before the concrete is placed on the deck plate 1. Therefore, it takes time and labor, and the process in the construction work of the reinforced concrete floor slab is It may be annoying and may interfere with the work. In addition, the position cannot be changed after the insert stud is driven. In the latter method of attaching the hanger to the leg 2 having a hollow triangular cross section, there is no catching part between the concrete and the deck plate 1, so the ceiling plate and various members for electrical installation, air conditioning and disaster prevention are suspended and supported on the hanger. Then, the load easily separates the concrete and the deck plate 1. Moreover, since the inside of the leg 2 is hollow, the strength of the deck plate 1 is insufficient.

[0004]

[Problems to be solved by the device]

 Therefore, in the present invention, the hanger can be attached after placing concrete on the deck plate, and the position of the hanger can be easily changed.Furthermore, the ceiling plate and various members for electrical installation, air conditioning, and disaster prevention are hung on the hanger. The purpose of the present invention is to provide a grooved deck plate for hangers, which can be prevented from peeling off from concrete even if it is supported underneath and the strength of the upper deck plate itself can be improved.

[0005]

[Means for Solving the Problems]

 Means for Solving the Problems The grooved deck plate for a hanger according to the present invention has one to several longitudinally extending legs on the lower surface at intervals in the horizontal direction of the horizontal plate, and has one side end. In the deck plate where the connecting piece extending in the longitudinal direction at a distance from the leg is bent downward and the both ends of the leg are crushed to form the hooking pieces, the center of the leg or the leg and the connecting piece is formed. In the middle of the above, a rib which is formed downward and has a narrowed opening is formed in the longitudinal direction, and both ends thereof are crushed and closed.

[0006]

[Action]

 The grooved deck plate for a hanger of the present invention configured as described above is a hanger bolt screwed into the locking metal fitting by inserting and locking the locking metal fitting of the hanger into the narrow strip groove of the opening. Since it is possible to suspend and support the ceiling board and various members for electrical installation, air conditioning, and disaster prevention, the hanger can be attached to the deck plate after placing concrete, and the attachment position is the longitudinal direction in the strip groove. Can be changed arbitrarily. Further, even if the load of various members suspended and supported is applied to the rib that forms the strip groove, the rib is engaged with the concrete, so that the deck plate is not peeled off from the concrete. The ribs also increase the strength of the flat deck plate.

[0007]

【Example】

 An embodiment of a grooved deck plate for a hanger according to the present invention will be described with reference to the drawings. In FIG. 1, three legs 11 each having a hollow triangular cross-section extending in the longitudinal direction are provided in parallel on the lower surface side of a horizontal plate 10 at regular intervals in the width direction, and the leg 11 is spaced at one side end. Then, a connecting piece 12 extending in the longitudinal direction is bent downward at a right angle, and both ends of the leg 11 are crushed to form a flat hooking piece 13 at both ends of the plate 10 orthogonal to the leg 11. In the deck plate, a rib 15 which is closed downward at the center between the legs 11 and which forms a dovetail groove 14 of a narrowed opening is provided in parallel with the one leg 11 in the longitudinal direction, It is a grooved deck plate 16 for hangers whose both ends are crushed and closed.

In FIG. 2, one leg 11 having a hollow triangular cross section is provided only at the other end of the horizontal plate 10, and a strip dovetail is formed in the middle of the connecting piece 12 bent at one end. A rib 15 for forming a groove 14 is provided in the longitudinal direction in parallel with the one leg 11, and both ends of the rib 15 are crushed to close the grooved deck plate 16 '.

In the embodiment of FIG. 1, the rib 15 for forming the dovetail groove 14 is one in the center between the legs 11, but one rib 15 may be provided between each leg 11, and a total of two ribs may be provided. One rib 15 for forming the dovetail groove 14 may be provided only between the end connecting piece 12 and the leg 11, and a total of three ribs 15 may be provided between each leg 11 and between the connecting piece 12 and the leg 11. It may be provided.

The deck plates 16 and 16 ′ of FIGS. 1 and 2 have three legs 1 and one leg 11, but may have two legs 11.

[0011] The grooved deck plates 16 and 16 'for hangers of the embodiment configured as shown in Figs. 1 and 2 are engaged with the hanger 17 in the dovetail groove 14 of the strip as shown in Fig. 3. Since the metal fitting 18 is inserted and locked, and the hanger bolt 19 screwed to the metal fitting 18 can suspend and support the ceiling plate and various members for electrical installation, air conditioning, and disaster prevention, the deck plate 16 of the hanger 17 can be suspended. , 16 'is preferably attached after the concrete 20 has been poured, and the attachment position can be arbitrarily changed in the longitudinal direction of the dovetail groove 14. Further, even if the load of various members suspended and supported is applied to the rib 15 which forms the dovetail groove 14, since the rib 15 is engaged with the concrete 20, the deck plates 16 and 16 'are separated from the concrete 20. Never. Further, the ribs 15 enhance the strength of the flat deck plates 16, 16 '.

Although the hanger groove is the dovetail groove 14 in the above embodiment, any cross-sectional shape may be used as long as it is a strip groove having a narrow opening. Further, the hanger which is inserted and locked in the narrow band groove of the opening is not limited to the one shown in FIG. 3, and various known hanger shapes can be appropriately selected and used.

[0013]

[Effect of the device]

 As described above, since the hanger grooved deck plate of the present invention can attach the hanger to the band-shaped groove after placing concrete, it does not complicate the process of constructing the reinforced concrete floor slab and causes a trouble in the work. Never. However, the mounting position of the hanger can be arbitrarily changed in the longitudinal direction within the band groove. Also, even if the load of the ceiling board suspended and supported by the hanger or various members for electrical installation, air conditioning, and disaster prevention is applied to the rib that forms the band-shaped groove, the rib is engaged with the concrete, so the deck plate is made of concrete. The flat deck plate does not come off and the ribs add strength.
