Abstract

For enhanced strength and resistance to bending stress without any increase in weight, a deck plate 1 has downwardly bent edge margins 2, 3 and, distributed throughout, a plurality of openings 4 with bent-down rims (8, Fig. 3) therearound. The openings are preferably laterally elongated and arranged in rows, and adjacent plates may be interlinked by provision of engage inwardly and outwardly projecting flanges 5, 7 on the longitudinal edge margins 2. <IMAGE>

Description

SPECIFICATION Deck plate This invention relates to deck plates which are suitably used as floor material of a storehouse or undercover car park, the covering of a waterway, or the surface covering of roads and runways.
Various improvements have been proposed and made to deck plates of the prior art in an attempt two reduce the weight of each individual deck plate and to make it possible for a plurality of deck plates to be joined together. However, no attempt has been made to reinforce or strengthen each deck plate against possible bending stress.
When it is intended to use such deck plates as the surface covering of a runwayforaeroplanes,for example, the deck plates will inevitably be subjected to great impact forces. In such an application ofthe deck plates, reinforcement of each deck plate against bending stress is essential.
Accordingly, it is the object of this invention to provide a new and novel deck plate which has a reinforced strength without increasing its total weight.
In order to attain the above-mentioned object, this invention provides a deck plate comprising a plate member having downwardly bent edge margins along its lateral and longitudinal edges and, provided throughout, a plurality of openings with bent-down rims therearound, said openings being spaced a predetermined distance away from one another in lateral and longitudinal directions of said plate member.
The downwardly bent edge margins and the bent-down peripheral rims ofthe openings impart to the deck plate an improved strength or resistance against bending stress.
The invention will be described, by way of example, with reference to the accompanying drawings, in which: Figure lisa plan view of a preferred embodiment of a deck plate according to this invention; Figure2 is a cross-sectional view of the deck plate taken along the line A-A in Figure 1; Figure 3 is an enlarged, fragmental cross-sectional view ofthe deck plate taken along the line A-A in Figure 1; Figure4is a cross-sectional view of the deck plate taken along the line B-B in Figure 1; and Figure 5is an enlarged, fragmental cross-sectional viewofthe deck plate taken along the line B-B in Figure 1.
With reference to the drawings, a preferred embodiment ofthe deck plate ofthe invention comprises a plate member 1 made of a metal sheet.
The lateral and longitudinal edges of the plate member 1 are bent downward to form downwardly extending edge margins 2 and 3, respectively. Also a pluralityof openings4areformed all overtheplate member 1 so that they are spaced a predetermined distance away from one another in both lateral and longitudinal directions ofthe plate member 1.
Asshown inFigure2,theendofoneofthe downwardly extending lateral edge margins 2 is bent inwardly to form an inwardly bent end portion 5, while the end of the other downwardly extending lateral edge margin 2 is bent outwardly to form an outwardly bent end portion 7 with its outermost end 6 slightly projecting upward. Similar such deck plates when laid side-by-side may then be held together by the inwardly extending edge margin 5 of one plate member 1 engaging with the outwardly extending edge margin 7 of the adjacent plate member 1.
The openings 4 are elongated laterally and the perimeter of each of the openings 4 is turned inward to provide an inwardly extending rim 8. The lateral rim portions of each inwardly extending rim 8 are preferably slanted atOto 5" with respecttothe vertical, as indicated by the reference angle A in Figure3,whilethelongitudinal rim portionsofthe inwardly extending rim 8 are preferably slanted at about 45" with respect to the vertical, as indicated by the reference angle B in Figure 5.
A plurality of reinforcing beams 9 may suitably be provided on the under surface of the plate member 1 sothattheyextend longitudinally, in paralleltothe bent edge margins 3 and between adjacent rows of the openings 4.
The presence of the downwardly extending edge margins 2,3 along the lateral and longitudinal edges of the plate member 1 as well as the inwardly extending peripheral rim 8 around the openings 4 is effective to give the deck plate an improved strength against bending stress. Thus, bending and deflection ofthe deck plate does not occurwhen the deck plate ofthe invention is used in applications where itis subject to severe impact forces. For example, deck plates in accordance with the invention may suitably be used as the floor material or covering of a covered car park, orthe covering of a waterway, orto form part of a road, or the surface covering of an airfield runway.
Variations in the detail ofthe deck plate structure are, of course, possible within the scope ofthe following claims.
1. A deck plate comprising a plate member having downwardly bent edge margins along its lateral and longitudinal edges and, provided throughout, a plurality of openings with bent-down rimstherearound, said openings being spaced a predetermined distance away from one another in lateral and longitudinal directions of said plate member.
2. A deck plate as claimed in Claim 1, wherein the openings are formed in the shape of laterally extending elongated openings.
3. Adeck plate as claimed in Claim 2whereinthe lateral rim portions and the longitudinal rim portions of the bent-down rims around the elongated openings have a slanted angle of 0 to 5 and a slanted angle of about 45" respectively.
4. A deck plate as claimed in any preceding claim wherein a plurality of reinforcing beams are provided on the under surface ofthe plate member and extend parallel to the longitudinal edge margins.
