Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel beam tip metal fitting used for mounting an upper runner below a steel beam.

[0002]

2. Description of the Related Art Many high-rise buildings are constructed in S type. As a method of attaching the upper runner to the lower side of the steel beam at the time of the partition construction in this S structure, first, LGS (reinforcing material)
Is welded to a steel beam, and the upper runner is joined to the LGS.

[0003]

However, by performing welding, deterioration of the steel frame due to heat, fire resistance due to heat transfer, etc.
Deterioration of heat insulation performance occurs. In addition, qualified workers must be deployed to perform welding, which increases construction costs. In addition, since the quality of welding varies depending on the skill of the worker, the construction quality tends to be unstable. In addition, it takes time for safety measures such as attention to fire. In addition, since the refractory coating, the coating, and the like are damaged by welding, repair is required, and it takes time.

In view of the above circumstances, the present invention is directed to an interior member installation metal used for mounting an upper runner below a steel beam, and which does not require welding for attachment to the steel beam, and which is convenient. The purpose is to provide.

[0010]

As described above, according to the first aspect of the present invention, welding is not required when attaching an interior member (runner, ceiling, air conditioning piping, cable, etc.) to a steel beam. . Therefore, the deterioration of the steel frame due to heat and the deterioration of the fire resistance performance and heat insulation performance due to heat transfer do not occur. Also, since there is no need to arrange a worker having special skills such as welding qualification, the construction cost is reduced. Further, since the mounting of the interior member mounting hardware is very easy, there is little difference in quality due to the skill of the worker. Therefore, the construction quality is stable. In addition, since no fire or the like is used, there is no need for safety measures. Also, since the construction method does not damage the refractory coating and the coating, repair after the construction is unnecessary.

According to the second aspect of the present invention, the runner can be conveniently mounted on the steel beam without welding.

According to the third aspect of the present invention, the versatility is high because the U-shaped spring member can cope with flange portions having different thicknesses.

FIG. 1 is a view showing a state in which a runner is installed using a metal fitting attached to a steel beam, and FIG.
FIG. 3 is a perspective view of the tip fitting, and FIG. 3 is an assembly view of the tip fitting.
In the floor space of the building, as shown in FIG. 1, a wall base material 30 for installing a partition wall is provided. The wall base material 30 has a pair of runners 32 (interior members) installed on the floor side and the ceiling side, respectively (the floor side runners are not shown). A stud 3 is provided between the pair of runners 32.
5 is provided, and a wall member (not shown) is installed on the stud 35.

As shown in FIG. 1, the runner 32 on the ceiling side is installed via a metal fitting 20 (an interior member installation hardware) attached to the steel beam 10 located on the ceiling side. The steel beam 10 of the present embodiment has a web portion 10a and flange portions 10b, 10b at both upper and lower ends of the web portion 10a.
It is a shape steel.

As shown in FIGS. 1 to 3, the metal fitting 20 has a pair of engaging members 21 and 22 which are detachable from one flange portion 10b of the steel beam 10. The engaging members 21 and 22 are U-shaped spring members, and each of the engaging members 21 and 22 inserts both sides of the flange portion 10b in the width direction of the steel beam 10 into the inside of the U-shape. And is engaged with the flange portion 10b in the form. When the side of the flange portion 10b is inserted into the U-shape of the engaging members 21 and 22, the flange portion 10b is tightened from both upper and lower surfaces. As a result, the attachment of the engaging members 21 and 22 to the flange portion 10b is ensured without play. Also, it is possible to cope with flange portions having different thicknesses.

The engaging members 21 and 22 are provided with bracket portions 23 and 24 disposed below, respectively.
The bracket portions 23, 24 have bolt holes 23a, 24a.
Are formed respectively. A bolt 25 is provided between the bracket portions 23 and 24 so as to penetrate and penetrate the bolt holes 23a and 24a.
A nut 26 is screwed into 5 (fastening means). That is, the bracket portions 23 and 24 are fastened by the bolts 25 and the nuts 26 in a direction (width direction) of approaching each other.

A runner support 27 (interior member support) is provided at the lower end of the bracket 23. The runner support 27 in the present embodiment is a metal member having a C-shaped cross section that extends linearly in a substantially horizontal direction with a predetermined length (length greater than the width of the flange portion 10b). Runner support 27
The lower surface side of is a runner mounting portion 27b to which a runner can be mounted. A moving member 28 is provided on the lower end side of the bracket 24, and the moving member 28
7, and is slidable in the moving groove 27a. That is, the pair of engaging members 2 is formed by the moving groove 27a and the moving member 28.
A moving mechanism 29 that enables relative movement of the members 1 and 22 in the width direction is configured.

The metal fitting 20 is constructed as described above. The above-mentioned runner 32 on the ceiling side is mounted and fixed at an appropriate position in the runner mounting portion 27b of the runner support 27 via a pin 33 or the like. I have. Although not shown in the figure,
A plurality of similar fittings 20 are installed at predetermined intervals in the longitudinal direction of the steel beam 10, and one runner 32 is attached across the plurality of fittings 20.

In order to attach the metal fitting 20 to the steel beam 10, first, the moving member 28 is attached to the runner support 27.
Is slidingly moved to slightly widen the interval W between the engaging members 21 and 22, and the engaging members 21 and 22 are connected to the steel beam 1.
0 flange 10b. After the engagement, the space between the brackets 23 and 24 is tightened with bolts 25 and nuts 26. Thus, the metal fitting 20 was securely fixed to the steel beam 10.

Similarly, a plurality of other metal fittings 20 (not shown) are attached to the steel beam 10. After that, the runner 32 is attached so as to be fixed in each of the plurality of metal fittings 20. The runner support 27 of the metal fitting 20 has a predetermined length in the horizontal direction.
It can be set freely within the range of the length of the runner support 27.

As described above, the runner 3 is located below the steel beam 10.
By using the metal fittings 20 when installing 2,
The welding to the steel beam 10 is unnecessary. Therefore,
Deterioration of the steel frame due to heat and deterioration of fire resistance and heat insulation performance due to heat transfer do not occur. Also, since there is no need to arrange a worker having special skills such as welding qualification, construction costs are reduced. Also, since the mounting of the metal fittings 20 is very simple (a tool can be used only with a wrench), there is little difference in quality due to the skill of the worker. Therefore, the construction quality is stable. In addition, since no fire or the like is used, there is no need for safety measures. Also, since the construction method does not damage the refractory coating and the coating, repair after the construction is unnecessary.

When the above-mentioned metal fitting 20 is adopted,
Since the removal of the metal fitting 20 from the steel beam 10 is easy, remodeling such as a change in layout is also easy. In addition, since the detached metal fittings 20 can be reused, members can be saved and industrial waste can be reduced, which is convenient.

The hardware for mounting the interior member such as the above-described metal fitting 20 supports not only the interior member such as the runner 32 but also the ceiling, the air-conditioning piping, and the cable via, for example, fishing bolts. It can also be used for such purposes. In any case, various interior members may be supported by the interior member support such as the runner support 27.
