Abstract

PROBLEM TO BE SOLVED: To simplify construction for joining intersection points of ceiling joist materials together and firmly join the ceiling joist materials together.SOLUTION: "U-shaped" holding walls for holding a ceiling joist material by bending one sheet metal are provided on both right and left sides in front of a principal-member holding hanging wall that is configured by being bent downward centering on an upper-end flat plate of a suspended-ceiling ceiling-joist joint metal, respectively. The ceiling joist materials are inserted from below, and the materials are joined and fixed via the suspended-ceiling ceiling-joist joint metal.

Description

  The present invention relates to a hanging ceiling edge joint metal fitting used for a joint portion of these base materials (field edge materials) when a ceiling of a house, a store, an office or the like is formed.

Normally, when constructing a ceiling, the edge material that supports the gypsum board, etc. of the finishing material is assembled in a lattice shape as the base material, but the base material used as the base material is a light steel frame of wood or metal, etc. ing.
In the case of wood, nails or screws are joined to each work with a metal screw or the like in the case of lightweight steel frames.

The function of the hanging edge edge fitting hardware of the field edge material is to join each edge edge material gathered at the intersection point used at the intersection point of the edge edge material, and easily attach it to horizontal materials such as beams to ensure the ceiling level is maintained. Therefore, noise caused by propagation of vibrations from the upper floor is reduced.
The priority attachment order and direction of the edge material gathered at the intersection junction are determined from the load bearing condition and the like.
In particular, in the case of a field material using wood or the like, unstable construction occurs due to slanting of nails, screws, or the like.

  As described above, in the construction by the conventional construction method, skillful skills are required to surely join the respective margin materials while keeping the level, and when there are many joints, a long construction time is required. It is necessary, and there is a risk of falling off when the construction is unstable due to slanting with a nail or the like.

In addition, the ceiling base material is basically suspended from a horizontal member with a space of about a centimeter to reduce vibration and noise on the upper floor, and absorbs vibration without being joined to structural members. The ceiling is maintained as a ceiling, but the joint is extremely fragile and inaccurate.
The present invention has been made in view of the above points, and the purpose of the present invention is to join by simple and accurate construction to anyone without changing the conventional construction without requiring skilled skills. This is to ensure the strength of the part at low cost.

  The hanging edge edge joint metal fitting of the field edge material of the present invention that achieves the above-mentioned object has a wall that hangs from a central flat plate part that is bent one sheet metal and has four rectangular holes at the upper end of the plane, It has a simple shape in which a sandwiching space is formed only by folding it into a “cono” shape with both sides of the hanging wall facing each other.

Since the ceiling base field edge material is bonded overhead, it is required to be able to be inserted and installed from below the holding wall space constituted by the holding wall of the suspended ceiling edge bonding hardware.
Overhead work is simplified by temporarily holding and holding the edge material by holding the holding walls on both sides of which the width of the holding wall space is narrowed, and the edge material is held on the holding wall of the suspended ceiling edge joint hardware. Therefore, the installer can release his / her hand, and accurate construction is possible.

Best mode for solving the problems

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 relate to an embodiment of the present invention, FIG. 1 is a partial cross-sectional perspective view showing a state in which a field edge material is suspended from a suspended field joint metal fitting, and FIG. 2 is a field edge material to a suspended ceiling joint hardware. FIG. 3 is a perspective view of a suspended metal fitting, and FIG. 4 is a perspective view of a suspended joint metal fitting.

  As shown in FIG. 1 and FIG. 2, this suspended ceiling edge joint metal fitting A is provided in sandwiching spaces s1 and s2 constituted by sandwiching walls w each of which is made of bent sheet metal. The structure is such that the field materials 2, 3 and 4 are joined together via the suspended Amagino joint metal fitting A, and the field margin materials 2, 3 and 4 are fixed to the suspended Amagine junction hardware A. It fixes with the screw | threads a and se from the outer surface of the material clamping wall w and Aw.

The lower part g of the sandwiching wall is slightly opened outward to facilitate the insertion of the field material from below, and the lower part of the sandwiching wall Aw for inserting the main field material 2 is cut obliquely to be gc, All the clamping walls are narrowed inward in order to temporarily hold the edge material.
In addition, the hanging metal fitting Tp of the hanging ceiling metal fitting is provided with protrusions J2 on the three surfaces other than the hanging portion of the central flat plate Hp and bent upward, and to the horizontal member of the narrow hanging hardware Tp. The fixed portion J1 is provided with a horizontally long adjustment hole f between the screw holes so that the length can be adjusted by bending and cutting.

  The suspension joint A is stably fixed by the projections J2 provided on the three sides of the flat plate of the suspension metal Tp, and if these projections J2 are inclined toward the center or outward, they are caused by vibration or the like. There is no possibility that the suspended ceiling joint hardware A will fall off from the suspended hardware Tp.

  Furthermore, by attaching and fixing synthetic rubber G1 etc. to the back of the attachment part of the hanging hardware Tp to the horizontal member 1 and the like, and by attaching the same synthetic rubber G2 to the flat plate portion of the hanging hardware, And can be expected to attenuate vibrations.

The rectangular holes k1, k2, k3, and k4 with the same dimensions and the same shape opened at four places on the flat plate Hp of the suspended hem joint A can be inserted from either direction and can be suspended. The order of construction of the timber edge material 2 and the short material rim material 3 and 4 that goes directly to it is inevitably determined.
Moreover, since the short material field edges 3 and 4 can be used even in materials scattered on the site, it leads to ecology.

For example, in general, a member of 45 mm × 45 mm is often used for the field edge material, and it is reasonable to set the width of the holding wall of the suspended field edge joint metal to 45 mm in the width of the field edge material. is there.
In addition, since the cross-sectional dimensions of the horizontal member are also different and are determined by the load conditions, the dimensions of the hanging hardware are also adjusted to the horizontal member with a small cross-section so that an adjustment hole f can be easily cut as shown in FIG. Many cases can be handled.

As mentioned above, although embodiment and the Example of this invention were described, the scope of the present invention is not limited to this.
For example, it can be used when a lightweight steel frame is used, and can be appropriately selected according to the material and the situation without problems even when it is attached to the wall.
