Abstract

PURPOSE:To fix respective parts with different heights by only one kind of fixing metal fitting, by providing a plurality of contacts with different heights at one end of the fixing metal fitting. CONSTITUTION:A fixing metal fitting 11 is made to have a form with a U-shaped section and opened at the top and cut to form a step so that the half part of one longitudinal end side in the upper end of a pair of side pieces oppositely positioned, gets tower toward the front end and it is provided with three contacts 13, 14, 15 with different heights respectively. When a floor plate is fixed at the lowest position where the thickness of a packing 2 is thinnest, the upper end face of the highest contact 13 is fixed to contact it and the fixing protrusion 16 at the front end of the contact 13 is fixed in the inside of the lip 6 of a beam 1 and held so as not to slip off. And the contact 17 of the other end side is positioned to get in contact with the rear face of the floor plate 3 and the front end of a bolt 19 inserted from the under side into a long bolt hole 18 is screwed into an insert nut 20 to fasten and fix it. In this way, contacts 13-15 with different heights are appropriately selected and used and hence, one same fixing metal fitting can be used in common.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for a floor plate of an outer corridor of an apartment, and more particularly to a device for fixing the floor plate with a drainage gradient.

[0002]

2. Description of the Related Art In an outer corridor of an apartment, a drainage gradient is provided on the floor in order to discharge the blown rainwater. In this case, the floorboard itself made of precast concrete, etc. should have the same thickness and the same surface, and the packing installed on the beam should be provided with an inclined surface, and the floorboard should be installed along the inclined surface. , There is a gradient.

FIG. 7 shows a structure of a floor provided with a slope by such a packing, and the floor is lowered from the main body of the building toward the outside on the upper surface of the arm beam (1) overhanging from the body of the building. A packing (2) having such a slope is installed, and floor plates (3) (3) are installed in parallel on the packing (2) to provide a slope on the floor surface.

In such a structure, when the floor plate (3) is fixed to the beam (1) on the back side with the metal fittings, the space between the floor plate (3) and the beam (1) is fixed at each fixed portion because of the inclination. Different from that, a fixing bracket corresponding to it is required. 8 and 9 show a conventional example of such a mounting structure. (4) is a fixing metal fitting, one end side of which is fixed to the back surface of the precast concrete floor plate (3) with a bolt (5) inserted from below, and the other end side is bent into a U-shape to form a groove. Side lip (6) of beam (1) made of shaped steel
It is in contact with the tip from below. And, FIG. 8 is a low place, and FIG. 9 is a high place.
According to such a difference in height, metal fittings (4) and (4) having different heights of the U-shaped portion that abuts on the beam (1) side are used.

[0005]

Therefore, in the conventional fixing device, a plurality of metal fittings having different height dimensions are required in accordance with the difference in height between the beam and the column, and Since there are many types, the cost is high and the work for ordering parts and selecting parts on site is complicated.

The present invention solves the above drawbacks of the prior art and fixes a floor plate installed with a slope on the beam to the beam on the back side of the floor plate by using only one kind of metal fitting. The purpose is to be able to fix each different part of.

[0007]

In order to solve the above-mentioned problems, in the fixing metal fitting of the present invention, one end side is brought into contact with the back surface of the floor plate installed on the beam, and the other end side is connected to the beam. A plurality of abutting portions having different heights are formed on the one end side in the fixing metal fitting that abuts on the downward surface of and fixes the floor plate with bolts inserted from the lower side.

In the above, it is conceivable to form a locking projection for the beam at each contact portion.

In the above-mentioned invention of claim 3 of this application, a metal plate is bent in a U-shape, and a pair of pieces facing each other are cut out at respective one end sides to make contact with different heights. It is characterized in that the portion is formed in a step shape.

[0010]

[Operation] According to the relative height between the beam and the floor plate, by selecting an abutting portion having a height corresponding to the relative height and abutting the abutting portion on the beam side, the same metal fittings are attached to the respective parts in the gradient direction. be able to.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a fixing member (11) of the present invention. This fixing bracket is basically formed by bending a thin metal plate to form a U-shaped cross section with the upper part open.
The upper end of the pair of side pieces (12) (12) facing each other, the half portion on one end side in the longitudinal direction, that is, the direction perpendicular to the bending direction, is notched in a step shape so as to decrease toward the tip,
Three contact portions (13), (14) and (15) having different heights are formed. In addition, at the tips of the contact parts (13) to (15),
The locking projections (16) (16) ... Are integrally formed so as to project upward. The half on the other end side that does not form the contact portions (13) to (15) is the side piece (12) (1).
2) The upper end is bent outward substantially horizontally to form a contact portion (17) with the floor plate. Furthermore, both sides piece (12) (12)
At the center in the width direction of the horizontal center piece (10) that connects the lower ends of the, the long bolt holes (1
8) has been formed.

2 to 5 show a mounting structure at each portion having a different height. Fig. 2 shows the case where the packing (2) is fixed at the lowest position where the thickness is the thinnest.
The upper end surface of the highest contact portion (13) of the contact portions (13) to (15) with respect to the stepped beam is brought into contact. At this time, the locking projection (16) at the tip of the abutting part (13) is attached to the lip (6) of the beam (1).
It is locked inside and is held so that it will not come off. In this state, the contact portion (17) on the other end side is brought into contact with the back surface of the floor plate (3), and the tip of the bolt (19) inserted from the lower side into the elongated bolt hole (18) is fixed to the floor plate. The insert nut (20) embedded in (3) is screwed in and fixed.

FIG. 3 shows a fixing structure at an intermediate height portion,
Similarly, the contact portion (14) having an intermediate height is brought into contact with the tip of the lip (6) of the beam (1). FIG. 4 shows a fixing structure at an intermediate portion where the floor surface is higher than that in FIG. At this time, the entire metal fitting (11) is tilted more than in the case of FIG. 4, but the same abutting portion (14) is used at different height parts within a range where it does not interfere with fixing. . FIG. 5 shows a fixing structure at the highest portion of the floor surface, which is fixed by using the lowest contact portion (15) of the metal fitting (11). FIG. 6 shows a fixing structure as seen from the back side of the fixing fitting (11).

[0014]

As described above, according to the present invention, by appropriately selecting and using the contact portions having different heights, it is possible to use the same fixing metal fittings commonly for each part of the floor plate having the slope. You can Therefore, only one type of parts is required, and the same parts can be mass-produced to reduce the product cost, and since the same parts are used for all parts, part ordering work and part selection work on site are possible. The effect that becomes easy is acquired.
