Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention prevents the deterioration of the strength of a double-floor rectangular floor panel when it is provided with a rectangular notch opening for fitting and mounting large equipment such as a composite outlet. The present invention relates to a reinforcing metal fitting.

[0002]

2. Description of the Related Art When a number of rectangular floor panels made of concrete, synthetic resin, wood, etc. are supported adjacent to each other at a fixed height on the floor base, a free access type double floor is formed.
It is generally practiced to provide a notch opening for attaching a wiring device on one edge of the floor panel. If the wiring equipment to be attached is a large-scale equipment such as a composite outlet, the above-mentioned notch opening is also made to have a large size, but this reduces the strength of the floor panel, resulting in insufficient load support. A support member is disposed between the floor panel around the opening and the floor base to reinforce.

[0003]

A means for preventing the concave deformation of the floor panel by inserting a supporting member between the floor panel and the floor base is a double floor construction and the floor panel support thereafter. Not only is the work of adjusting and changing the level cumbersome, but there is the drawback that the freedom of wiring in the underfloor space is limited.

DISCLOSURE OF THE INVENTION The present invention is directed to a case where a relatively large rectangular cutout opening is provided on the panel surface from one side edge of the square floor panel for forming a double floor. This is a rectangular frame-shaped metal fitting that fits on the floor panel. That is, the present invention is a floor panel cutout opening characterized in that three sides of a square mold formed by a U-shaped cross section are floor panel fitting edges with the upper and lower horizontal horizontal pieces of the cross section being outside the frame. Department
The main point is the reinforcing metal fittings .

The present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of the reinforcing metal fitting 1, and FIGS. 2 and 3 are a cross-sectional view and a top view of a metal mold material 10 which is a forming material of the reinforcing metal fitting 1. As shown in FIG. 2, the mold member 10 is a vertical horizontal piece 1 which is bent at a right angle to one side from the upper and lower edges of the standing wall 11 and faces in parallel.
2 and 13 has a U-shaped cross section, and the material having the required length dimension is provided with the incision grooves 7 and 8 in the upper and lower horizontal pieces 12 and 13 at the required dimension intervals as shown in FIG. A line 9 is used as a split member having a required length, and the reinforcing member 1 having a rectangular frame in FIG. 1 is formed by using the split member.

The reinforcing metal fitting 1 bends the standing wall 11 at the positions of the cut grooves 7 and 8 formed in the material of the mold material 10 at right angles, so that the upper and lower horizontal horizontal pieces 12 and 13 facing each other are outside and the left edge 2 is formed. , A rear edge 3 and a right edge 4 are formed in series, and the dividing member is inserted between the left and right edges 2 and 4 of the front end standing wall 11 with the standing wall 11 as the outer side, and both ends thereof are left and right edges 2.
4 to form a front edge 5 by welding or bonding. In the above-mentioned quadrangular frame, the pair of opposite edge lengths facing each other are the same, and by adjusting the two pairs of edge lengths, the space shape in the frame can be made into a square or a rectangle of arbitrary dimensions.

In FIG. 4, the length of one side is usually 40 to 60 cm.
For a relatively large rectangular notch opening 30 formed from one edge of the square floor panel 20 to the center of the plate, the reinforcing metal fitting 1 of the present invention is attached to the left edge 2, the rear edge 3, and the right edge 4, respectively. of fitting the floor panels periphery between the upper and lower horizontal bars 12, 13, the vertical wall 11 side of the front edge 5 and fitted as allowed to coincide with the outer peripheral surface of the floor panel 20, on a surface view illustrating a reinforcement state Yes, reference numeral 21 is a support leg metal fitting that is erected at four corners of the floor panel 20. FIG. 5 is a side view showing a state in which the floor panel 20 is placed on the floor base ground F.

FIG. 6 is a perspective view of a reinforcing metal fitting 1'of another embodiment, and FIG. 7 is a top view of a mold material 10 'having a U-shaped cross section of its constituent materials. Is different in that the front edge 5 ′ is connected and bent to the right edge 4 at the standing wall 11 by the cutting edge 9 ′ without being cut, and the end face thereof is abutted and fixed to the surface of the end standing wall 11 of the left edge 2. Left edge 2, rear edge 3, of reinforcing metal fitting 1 '
There is no change in that the three sides of the frame of the right edge 4 form the floor panel fitting edge, and it can be used in the same manner as in the previous embodiment.

[0009]

The reinforcing metal fitting of the present invention has a rectangular frame formed by a U-shaped cross-section material, and the frame itself has a large rigidity, and the three sides of the frame are the corners of the floor panel with rectangular cutout openings. By fitting and mounting the floor panel on the floor panel, the floor panel can be reinforced so as to enhance the bending resistance, and a stable support frame for a wiring device or the like can be provided.

[Example] 23 mm as a floor panel (A) for a double floor
Using a wire mesh reinforced glass fiber reinforced cement plate having a thickness of 50 cm × 50 cm and a weight of 10 kg, a rectangular portion having an opening width of 23 cm and a depth of 24 cm is cut out at the center of one edge of the floor panel (A) to form an opening forming floor panel. (B). The reinforcing metal fitting of the present invention having a rectangular frame as shown in FIG. 1 which can be fitted into the notch opening is formed by a steel plate having a thickness of 2.4 mm. The vertical wall height is 28 mm and the horizontal width is 10 mm. Manufactured by using the above-mentioned mold material, the epoxy adhesive is applied to the inner surfaces of the three sides of the fitting, and the fitting is fixed in the notched opening of the opening forming floor panel (B) to form a reinforced floor panel (C). .
The floor panel (A), the opening forming floor panel (B) and the reinforced floor panel (C) were subjected to a strength test in which a concentrated load is applied to the center of the floor panel under the laid condition shown in FIG. Got

[0011] As shown in the above test results, the strength deterioration of the floor panel due to the formation of the notch opening can be reinforced by fitting the reinforcing metal fitting of the present invention to almost the same level as the original panel.

[0012]

EFFECTS OF THE INVENTION The reinforcing metal fitting of the present invention can be easily manufactured by using only a U-shaped cross-section mold member, and the shape of the mold member makes it possible to easily and effectively perform fitting reinforcement to the floor panel incision with three sides as fitting edges. Therefore, the double floor forming work and the maintenance work after the double floor forming work can be performed without causing troubles such as the troublesome work of the reinforcing means by the intervening arrangement of the conventional support member and the limitation of the freedom of wiring of the underfloor space by the intervention support member. The efficiency can be improved.
