Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temporary fixing metal fitting for a horizontal frame used for a joist on a floor base or a field edge on a ceiling base.

[0002]

[Prior Art]

 Conventionally, for example, when constructing a floor, multiple joists as horizontal frames are installed on the joist mounting plate with adjustable height of multiple joist supports installed on the floor slab. The joists are adjusted in height to set the joists at a predetermined height above the floor slab, that is, the joists horizontal level, and the joists are attached to the top of the joists.

[0003]

[Problems to be solved by the device]

 In particular, when constructing a large-scale floor, it is necessary to use a large number of joist supports, but with the method described above, each joist mounting plate of a large number of joists can be supported horizontally. Since it has to be adjusted to the level, it is difficult to adjust the level and it takes time and effort to construct.

Therefore, after holding another upper horizontal frame in an orthogonal state on the joist at a certain height above the floor slab, that is, at the horizontal level of the joist, the joist below it is temporarily fixed. If the joists are held in contact with the lower surface of the upper horizontal frame by using, the joists will be held at the horizontal level position, and it does not take time and effort to adjust the level. After holding the joists, remove the temporary fittings and the upper horizontal frame.

The present invention provides the above-mentioned temporary fixing metal fitting, which enables one-touch temporary fixing of horizontal frames such as joists and rims.

[0006]

[Means for Solving the Problems]

 The temporary fixing metal fitting of the present invention temporarily fixes the lower horizontal frame 2 in a substantially orthogonal state so that the lower horizontal frame 2 abuts on the lower surface 1a of the upper horizontal frame 1 whose both ends are held and passed horizontally. A support portion 3a which is formed by molding and extends in a direction perpendicular to the lower horizontal frame 2 in contact with the lower surface 2a of the lower horizontal frame 2 and both side surfaces 2b of the lower horizontal frame 2 which stand upright from both ends of the support portion 3a. , 2b and the hanging portions 3c, 3c facing one side surface 1b of the upper horizontal frame 1 and the ends of the hanging portions 3c, 3c, and extending in the direction of the upper surface 1t of the upper horizontal frame 1. As described above, the lower portions 3e, 3e have locking portions 3d, 3d that are in contact with the upper surface 1t of the water flat frame 1, and the hanging portions 3c, 3c are bent in a direction in which they are separated from each other. Has been.

[0007]

[Action]

 The rings of the locking portions 3d and 3d of the temporary metal fitting 3 are gripped with fingers and the locking portions 3d and 3d are brought to the upper surface 1t side of the upper horizontal frame 1. When the fingers are released, the locking portions 3d, 3d are urged in the directions away from each other by the bending force of the hanging portions 3c, 3c, and the lower portions 3e, 3e of the locking portions 3d, 3d are brought to the upper surface 1t of the upper horizontal frame 1. When locked, the upper surface 2t of the lower horizontal frame 2 contacts the lower surface 1t of the upper horizontal frame 1, and the lower horizontal frame 2 is temporarily fixed to the upper horizontal frame 1.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 1 denotes an upper horizontal frame having a square cross-section which is held horizontally at a position where both ends have a constant height above the floor slab S, that is, at a horizontal level of a joist, which will be described later. The ribs 1s extending at right angles to the extension direction of the upper horizontal frame 1 are formed at a predetermined pitch. Numeral 2 is a joist having a square cross-section as a lower horizontal frame which is installed so as to come into contact with the lower surface 1a of the upper horizontal frame 1 and is temporarily fixed to the upper horizontal frame 1 by a temporary fixing metal fitting 3 in a substantially orthogonal state. The temporary fixing metal fitting 3 is formed by forming an elastic wire, and is a support portion which extends in a direction perpendicular to the joist 2 in contact with the lower surface 2a of the joist 2 located below the central portion in the extension direction of the upper horizontal frame 1. 3a and the bent portions 3b, 3b formed at both ends of the support portion 3a, rise up and face both side surfaces 2b, 2b of the joist 2 and one side surface 1b of the upper horizontal frame 1. Hanging portions 3c, 3c, and the lower portions 3e, 3e that are formed at the tips of the hanging portions 3c, 3c and are formed in a substantially ring shape so as to extend in the direction of the upper surface 1t of the upper horizontal frame 1 so that the lower portions 3e, 3e are formed. Has locking portions 3d, 3d that come into contact with the upper surface 1t of the above, and the hanging portions 3c, 3c are provided with a deflection in a direction in which they are separated from each other.

The joist 2 is previously attached to a joist placement plate of a joist support table (not shown) with a belt or the like, and the joist placing plate is set so as to be able to move upward. Then, the temporary fastening metal 3 makes the upper surface 2t of the joist 2 contact the lower surface 1a of the upper horizontal frame 1, and in this state, the joist mounting plate is locked by an adjuster lock nut or the like. After locking the joist mounting plate in this manner, the temporary fixing metal fitting 3 and the upper horizontal frame 1 are removed, and the floor board is placed on the joist 2.

Next, a method of using the temporary fastening member 3 will be described. First, the side portions 2b, 2b of the joist 2 are sandwiched between the hanging portions 3c, 3c from below in the joist 2, and the rings of the engaging portions 3d, 3d are grasped with fingers, and the engaging portions 3d, 3d are horizontally leveled. Bring it to the upper surface 1t side of the frame 1. When the fingers are released, the locking portions 3d, 3d are urged in the directions away from each other by the bending force of the hanging portions 3c, 3c, and the lower portions 3e, 3e of the locking portions 3d, 3d are placed on the upper surface 1t of the upper horizontal frame 1. Lock on. At this time, the lengths of the hanging portions 3c, 3c are set so that the upper surface 2t of the joist 2 contacts the lower surface 1t of the upper horizontal frame 1.

According to the above-described embodiment, by using the temporary fastening member 3, the upper surface 2t of the joist 2 comes into contact with the lower surface 1a of the upper horizontal frame 1 held at the horizontal level of the joist 2. Therefore, the joist can be temporarily fixed to the upper horizontal frame 1 and held at the horizontal level position, and the labor for leveling can be greatly reduced.

Although the joist 2 is temporarily fixed to the upper horizontal frame 1 in the above-mentioned embodiment, the temporary fixing metal fitting of the present invention can be applied to temporarily fix the field edge of the ceiling base.

[0013]

[Effect of the device]

 As described above, in the temporary fixing metal fitting of the present invention, since the lower horizontal frame is temporarily fixed so as to abut the lower surface of the upper horizontal frame which is held horizontally at both ends, it is elastic. A support part that is formed by forming a wire and extends in a direction perpendicular to the lower horizontal frame in contact with the lower surface of the lower horizontal frame, rises from both ends of the support part, and faces both side surfaces of the lower horizontal frame. A hanging part facing one side of the upper horizontal frame and a tip of this hanging part are formed in a ring shape so as to extend in the upper surface direction of the upper horizontal frame, and the lower part is on the upper surface of the upper horizontal frame. Since the suspending portions have contacting locking portions and the hanging portions are bent in a direction in which they are separated from each other, temporary fixing of horizontal frames such as joists and field edges can be performed with one touch.
