Description

[Detailed description of the invention] The present invention relates to a lid reinforcing structure for an underfloor storage, and more specifically, two opposing rectangular frames whose peripheral lower surfaces are placed on a receiving frame attached to the opening edge of the underfloor storage. The present invention relates to a structure in which a reinforcing beam and a rectangular frame are fitted between sides.

Generally, a lid 1 that closes the opening of an underfloor storage A as shown in FIG. 1 is constructed by fitting the peripheral end of a lid plate 2 into a rectangular frame 3.
In order to reinforce the lid 1, reinforcing bars 4 are installed on two opposing sides of the rectangular frame 3, as shown in FIGS. 2 and 3, but conventionally, as shown in FIGS. , a notch 9 provided in a portion extending over a vertical piece 6 that projects upward from the tip of the lower horizontal piece 5 that forms the bottom surface of the rectangular frame 3 and a horizontal piece 7 that extends from the upper end of this vertical piece 6 at right angles to the vertical piece 6. The upper end of the reinforcing bar 4 is inserted into the back surface of the cover plate 2, the peripheral end of which is fitted between the upper horizontal piece 8 and the horizontal piece 7 of the rectangular frame 3, and the upper end of the reinforcing bar 4 extends outward. Mounting piece 1
0 is fixed, so if the cover plate 2 is attached to the rectangular frame 3 first, the end of the reinforcing bar 4 cannot be inserted into the notch 9, and the reinforcing bar 4 cannot be attached. Also, when placing the end of the lid 1 on the receiving frame 12 around the opening of the underfloor storage A, the reinforcing bar 4 is not directly supported on the receiving frame 12, so the lid 1 can be placed effectively. The problem was that it could not be reinforced.

The present invention was devised in view of the above points, and its main purpose is to facilitate assembly by allowing the reinforcing bars to be incorporated even after the cover plate and rectangular frame are combined.
Further, the reinforcing bar itself can be supported by a receiving frame disposed at the edge of the opening of the underfloor storage, thereby providing a lid reinforcing structure with a high reinforcing effect.

The present invention will be described in detail below based on embodiments shown in the drawings.

The lid 1 is constructed by attaching a rectangular frame 3 to the periphery of a lid plate 2. The lower surface of the periphery is placed on a receiving frame 12 attached to the periphery of an opening bored in the floor B, and the upper end is placed on the receiving frame 12. Box 1 locked to 12
This is to close the opening of the underfloor storage A formed by 3.

The rectangular frame 3 has a cross-sectional shape in which a vertical piece 6 extends upward from the tip of a U-shaped lower horizontal piece 5, and a horizontal piece 7 extends from the upper end of the vertical piece 6 at right angles to the vertical piece 6. It is formed by framing frame materials, and the peripheral end of the cover plate 2 is fitted between the U-shaped upper horizontal piece 8 and the horizontal piece 7, and the cover plate 2 is fitted into the upper half of the rectangular frame 3. It is.

The reinforcing machine 4 is installed between the centers of two opposing sides of the rectangular frame 3, and is located at the upper ends of both sides of the U-shaped member 4a, excluding both longitudinal ends of the U-shaped member 4a, which has a substantially U-shaped cross section. Mounting piece 1
0.10 is formed into a shape that extends outward at right angles, and both longitudinal ends thereof are fitted into notches 9 provided at the center of two opposite sides of the rectangular frame 3, and the mounting piece 10 is secured to the screw 15.
It is fixed to the back surface of the cover plate 2 with.

Here, the notches 9 are the horizontal piece 7 and the vertical piece 6, as shown in FIG.
The rectangular frame 3 is formed by cutting out a portion extending over the lower horizontal piece 5.
The end of the side reinforcing device 4 is inserted into the notch 9, and as a result, the rectangular frame 3 is first inserted into the cover plate 2.
Even after the reinforcing machine 4 is attached, the reinforcing machine 4 can be assembled into the rectangular frame 3.

Further, the reinforcing machine 4 fits within the notch 9 with its outer bottom surface flush with the outer surface of the lower horizontal piece 5, which is the outer bottom surface of the rectangular frame 3, and therefore,
As shown in FIG. 4, the end of the reinforcing machine 4 is placed on the receiving frame 12 together with the lower horizontal piece 5 of the rectangular frame 3, so that the reinforcing machine 4 can also support the load applied to the lid 1. It has the advantage of increasing the reinforcing effect.
