Abstract

(57) [Summary] [Purpose] Easily and securely attach the second floor panel and the ceiling hanging wooden bridge on the first floor to the floor beam without bolting or welding work. [Structure] On a side surface of the floor beam 1, a floor panel support metal member 4 is bent and formed in a shape that fits and supports in a space surrounded by the web of the floor beam 1 and upper and lower flanges. Then, a support piece 46 for temporarily placing the floor panel is connected to the upper flange contact piece 42 of the floor panel support metal 4, and a mounting piece 47 of a ceiling hanging tree receiver is connected to the lower flange contact piece 43. As a result, the second floor floor panel and the first floor ceiling tree bridge can be easily supported without fixing the floor panel support hardware 4 to the floor beam 1 by bolts, welding or the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a floor beam that simultaneously supports a floor panel 2 on the second floor side and a ceiling hanging bridge between the floor beam upper and lower flanges.

[0002]

[Prior art]

 When the floor panel 2 on the second floor and the ceiling hanging bridge on the first floor are supported on the floor beam 1, conventionally, as shown in FIG. The floor panel support hardware 4 for supporting the lower surface of the floor panel and the ceiling hanger support mounting hardware 5 are integrally provided on the web portion by welding or bolting, and the floor panel 2 is placed on the floor panel support hardware 4. After the temporary placement, the floor beam upper support member 3 and the frame members of the floor panel 2 are fastened with bolts, and the ceiling hanging tree is fixed to the ceiling hanging tree receiving object with screws.

[0003]

[Problems to be solved by the device]

 Therefore, in the conventional method, both the ceiling lumber receiving fitting 5 and the floor panel supporting fitting 4 are fixed by welding or bolting to the web portion of the floor beam 1 at predetermined positions. It takes a lot of time to install the and.

An object of the present invention is to eliminate the bolting and welding work and to easily and reliably attach the second floor panel and the ceiling hanging wooden bridge on the first floor side to the floor beam.

[0005]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above object. A floor panel supporting metal member is formed by bending on a side surface of a floor beam so as to be fitted and supported in a space surrounded by the floor beam web and upper and lower flanges. The floor flange support piece is provided with a support piece for temporary placement of the floor panel on the top flange contact piece, and a ceiling hanging tree bridge attachment piece on the bottom flange contact piece. The gist is that the floor panel on the second floor and the hanging bridge on the first floor can be easily supported without fixing the hardware to the floor beam with bolts or welding.

[0006]

[Work]

 On the side of the floor beam, install the floor panel support hardware that has the floor panel support piece and the ceiling hanging tree receiving attachment piece by inserting and fitting in the space surrounded by the upper and lower flanges, and fix the floor panel. Since it can be fixed at the same time with, it is possible to omit the work such as bolting and welding to the floor beam of the floor panel supporting metal as in the conventional case. In addition, it is easy to attach floor panels and ceiling hanging bridges.

[0007]

【Example】

 The structure of the floor beam of the present invention will be described below with reference to the illustrated embodiment. In the figure, 1 is a floor beam made of an H-shaped rope, 2 is a floor panel on the second floor having a required size and configuration, and this floor panel 2 is a floor panel supporting metal member 4 for temporarily placing the lower surface of the end frame 21. After being received, the floor beam upper support member 3 and the bolt B are fixed on the floor beam.

The floor beam upper support member 3 is U-shaped as shown in FIG. 2, and its both side plates 31 and 31 are opposed to each other, and the mounting holes 3H for fixing the floor panel 2 with bolts. 3H is perforated by 1 or 2 or more, and the end of the floor panel is prevented from being directly caught on the upper flange 11 of the floor beam between the opposing side plates 31 and 31, and the outer side surface of the end frame 21 of the floor panel 2 is abutted. Appropriately determined so as to touch. Then, the floor beam upper support member 3 is welded and fixed to the upper flange 11 as in the conventional case.

As shown in detail in FIGS. 1 and 2, the floor panel support hardware 4 for temporary placement has a metal plate having a required strength, and a web contacting piece 41 of a web abutting piece 41 which is placed along the side surface of the web 12 of the floor beam 1. An upper flange abutting piece 42 and a lower flange abutting piece 43 are formed by bending the upper end and the lower end almost horizontally and closely adhering to the lower surface of the upper flange 11 of the floor beam 1 and the upper surface of the lower flange 13, respectively. The lengths of the upper and lower flange abutment pieces 42, 43 are set to the width of the upper and lower flanges 12, 13, that is, the length from the web 12 to the flange end. Make it match.

Further, the tips of the upper and lower flange contacting pieces 42, 43 of the floor panel supporting hardware 4 are bent substantially vertically, and the hanging pieces 44, 45 facing each other are continuously provided. The leading ends of the hanging pieces 44, 45. Is bent so as to project horizontally outward to form a floor panel support piece 46 and an Arai hanging tree receiving attachment piece 47, and one or more attachment holes 4H are bored in the support piece 46 and the attachment piece 47.

Therefore, in order to attach the second floor panel 2 to the floor beam 1 using the hardware constructed as described above, the floor panel support hardware 4 is first attached from the side surface of the floor beam 1 as shown in FIGS. It is inserted so that it fits into the web 12 of the floor beam 1 and fits into the upper and lower flanges 12 and 13. Then, after temporarily placing the floor panel 2 on the supporting piece 46 of the floor panel supporting metal member, the side plate 31 of the floor beam upper support member 3 and the floor panel end frame 21 are brought into contact with each other, and their mounting holes are aligned with each other. The floor panel 2 is fixed by screwing a bolt B thereto.

Similarly, as shown in FIG. 1, floor panels 2 and 2 are attached from both sides of the floor beam 1, respectively. As a result, the floor panel supporting metal fittings 4 and 4 fitted in the web of the floor beam 1 are narrowed between the facing floor panels 2 and 2, so that they are firmly fixed to the web portion without bolting. The support piece 46 and the floor panel 2 are fixed with screws or nails from the attachment piece 4H.

Further, the ceiling hanging tree bridge 6 is mounted on the mounting piece 47 on the lower side of the floor panel supporting metal piece. This is done by inserting it between the support piece 46 and the mounting piece 47, which are vertically opposed to each other, of the floor panel support metal fitting 4 fitted and mounted on the floor beam 1, and then, from the mounting hole 4H of the mounting piece 47 to a screw or a nail. The ceiling hanging tree bridge 6 is fixed.

It should be noted that if the outer shape of the floor panel supporting metal member 4 having a flat corner shape in which the supporting member / mounting member is protruded is formed to be substantially the same size as the side surface of the floor beam or slightly larger, the supporting metal member has It may be possible to easily attach to the side surface of the floor beam by utilizing elasticity.

EFFECTS OF THE INVENTION The floor beam structure of the present invention is such that a floor panel supporting metal member is bent and formed on a side surface of the floor beam so as to be fitted and supported in a space surrounded by the floor beam web and upper and lower flanges. Since the upper flange abutting piece of the floor panel support has a support piece for temporary placement of the floor panel, and the lower flange abutting piece has a ceiling hanging tree support attachment piece, the floor panel is attached. Further, there is an advantage that workability and workability are improved because the floor panel supporting hardware is fixed to the floor beam at the same time by mounting the floor panel without bolting or welding.
