Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical mounting bracket, and more particularly to a floor surface of a building and a vertical bracket
(Also referred to as a support) and a vertical mounting bracket.

[0002]

2. Description of the Related Art Generally, in a skyscraper or the like, a flexible structure is preferable as an earthquake countermeasure. Therefore, conventionally, as shown in FIG. 4 which is shown in a vertical cross section, a cubic mounting bracket for fixing a floor surface 5 of a skyscraper and a column (a hoddle) 6 which is a pillar is one suitable for a flexible structure. It is used. That is, the conventional upright mounting bracket is integrally formed in a substantially L-shaped cross section including a horizontal portion 1 attached to the floor 5 side of the building and a vertical portion 2 attached to the upright 6 side of the building. A height adjustment bolt receiver 3 is attached to the upper end of the vertical portion 2 of the metal object by welding in parallel with the horizontal portion 1. The horizontal portion 1 has an elongated hole 1a for adjusting the position between the vertical 6 side and the floor surface 5 side and bolting the floor surface 5, and the vertical portion 2 has the elongated hole 1a. A long hole (bolt hole) 2a for tightening a bolt is provided on the side of the upright 6 and a surface that contacts the upright 6 is welded to a curved surface member 20 having a convex curved surface to form a conventional upright mounting bracket. is doing.
Also, a vertical bracket 6a attached to the vertical 6
The adjusting bracket 6b is welded to the adjusting bracket 6b, and the tip of the height adjusting bolt 6c attached to the adjusting bracket 6b with the nuts 6d and 6d is in contact with the height adjusting bolt receiver 3. By adjusting the height adjusting bolt 6c, the height relationship between the floor surface 5 and the upright 6 is adjusted, and the adjusted height is maintained by tightening the nuts 6d and 6d. The curved surface member 20 of the vertical portion 2 is usually a cubic bracket 6 in which the highest vertex of the convex curved surface R is the cubic 6.
It is held by being tightened with bolts 2b and nuts 2c in a state of being in contact with a, but when the skyscraper sways in the lateral direction due to an earthquake or the like, the upright 6 changes from a vertical state to an oblique state, and the upright 6 The upright bracket 6a attached to holds the upright 6 and the floor surface 5 while contacting each other at a position vertically displaced from the highest point of the curved surface R as if it were a tangent line. That is, in the event of an earthquake or the like, the flexible structure flexibly accepts that the cubic 6 changes to an angle other than the right angle with respect to the floor surface 5 due to the contact with the curved surface, so as to avoid damage to the building.

[0003]

However, according to the above-mentioned conventional example, since the curved surface member 20 is attached to the vertical portion 2 of the vertical mounting member by welding in forming the curved surface, unevenness occurs in the product strength. It took time and effort for production, required a skilled welding engineer, was not suitable for mass production, and had high cost. The present invention aims to solve such problems.

[0004]

In order to achieve the above object, the present invention provides the following vertical fitting. That is, the present invention is a horizontal portion attached to the floor side of a building, a vertical portion attached to the upright side of the building, and a height adjustment bolt receiver formed by bending an upper end portion of the vertical portion in parallel with the horizontal portion. Is a vertical mounting bracket having a substantially L-shaped cross section, the horizontal portion having a bolt hole for position adjustment and bolting to the floor surface. The portion has a bolt hole for bolting to the upright side, the surface contacting with the upright side is formed into a convex curved surface, and an upward protruding portion is provided on the upper portion of the vertical portion. It is a vertical mounting bracket.

[0005]

In the above structure, the convex curved surface provided on the vertical portion of the vertical mounting bracket is in contact with the vertical side, which is inclined due to the rolling accompanying the earthquake, while changing its contact position up and down like a tangent line. It has an effect. The height adjustment bolt receiver has its height adjusted by the height adjustment bolt. The bolt holes in the horizontal portion are slid and adjusted to adjust the horizontal distance between the vertical and floor surfaces, and then fixed and held by the bolts. The protrusion acts to prevent the height adjustment bolt from coming off from the abutment during lateral rolling.

Embodiments of the present invention will now be described with reference to the drawings, showing how the construction of the present invention is actually embodied, together with its operation. FIG. 1 is a perspective explanatory view showing an embodiment of the present invention, in which 1 is a horizontal portion made of a flat surface, and a vertical portion 2 forming a plane perpendicular to one end of the horizontal portion 1 is further provided. A height adjusting bolt receiver 3 is provided on the upper portion of the vertical portion 2 in parallel with the horizontal portion 1, and the overall shape is substantially L-shaped in cross section. In addition, the outside of the vertical portion 2 is formed into a convex curved surface R, and a protrusion 4 is provided on the upper portion of the vertical portion 2. Here, the horizontal portion 1, the vertical portion 2 including the curved surface R, the height adjustment bolt receiver 3, and the protrusion portion 4 can be continuously formed by extrusion integrally in the manufacturing process, and a process such as welding is performed. The greatest feature of the present invention is that it is not necessary at all. Further, the vertical portion 2 is provided with a long hole 2a which is a bolt hole, and the long hole 2a is set at a point where the tangent line contacting the curved surface R is vertical, that is, the position of maximum thickness. The elongated hole 2a is for mounting vertically with bolts and nuts as described later. The horizontal portion 1 is provided with an elongated hole 1a, which is for attaching to the floor surface with a bolt as described later. In addition,
Due to its structure, the height adjustment bolt receiver 3 not only receives the height adjustment bolt, but also plays a role of reinforcing the vertical mounting bracket.

FIG. 2 is an explanatory view of a usage state of the embodiment, which is shown in a vertical section. The horizontal part 1 of the embodiment is
It is attached to the filling material 5a on the floor surface 5 side with the bolt 1b through the long hole 1a. The long hole 1a allows the bolt 1b to slide, and allows the positional distance between the floor surface 5 and the upright 6 to be adjusted. Further, the vertical portion 2 is attached with the bolt 2b and the nut 2c through the elongated hole 2a so that the apex of the curved surface R contacts the vertical bracket 6a on the vertical 6 side. On the opposite side of the cube, a glass G for partitioning the inner and outer spaces of a skyscraper building is attached. Further, the height adjustment bolt receiver 3 has a height adjustment bracket 6b welded to the vertical bracket 6a on the side of the upright 6, and the height adjustment bolt 6c attached to the height adjustment bracket 6b with a nut 6d. The height is adjusted by. In this case, the tip end of the height adjusting bolt 6c is brought into contact with an appropriate position where it is difficult to separate from the height adjusting bolt receiver 3 in the event of an earthquake or the like. The protrusion 4 on the vertical portion 2 is provided to prevent the tip of the height adjusting bolt 6c from coming off.

FIG. 3 is a diagram for explaining the operation of the embodiment, and the operation when the cuboid 6 tilts obliquely from the vertical state when it sways sideways due to an earthquake or the like will be described. It shows that the contact position (the position in contact with the tangent line) between the vertical bracket 6a on the vertical 6 side and the curved surface R of the vertical portion 2 changes. That is, with respect to the curved surface R, the vertical bracket 6a on the vertical 6 side can contact like a tangent line. Therefore, when the vertical bracket 6a inclines due to rolling due to an earthquake or the like, the vertical bracket 6a and the The position in contact with the curved surface R moves and changes on the curved surface R. However, since the upright bracket 6a and the vertical portion 2 are fastened with the bolt 2b and the nut 2c passing through the apex of the curved surface R, the position where the tangent is in contact does not resist the fastening force of the bolt 2b and the nut 2c. Then, when the external force disappears, the contact position between the vertical bracket 6a and the curved surface R returns to the original position and the vertical bracket 6a returns to the vertical state. Further, the projection 4 at the upper portion of the vertical portion 2 of the upright mounting hardware has a height adjusting bolt 6c on the upright 6 side when the upright 6 is inclined due to an earthquake or the like.
The tip of the is prevented from coming off the height adjusting bolt receiver 3, and also acts as a restoring force.

As described above with reference to the embodiments, the present invention is a vertical fitting for fixing the floor surface of a skyscraper or the like and the vertical pillars, and includes the horizontal portion 1 and the curved surface R.
