This invention relates to frames and gratingsl and covers for drains of the kind in which both the grating or cover and the frame into which it fits are provided with surfaces which seat together when the grating or cover is placed in position.
One of the objects of the present invention is to construct a drainage frame and cover o'r grating of indefinite length so that it can conveniently be xed without extensive preparation of the ground.
i .Anotherl object of the present invention is to construct a drainage frame and cover or grating of indefinite length which can conveniently be handled and fixed without th'e use of skilled la bour.
A further object of the invention is to construct such a drainage frame and cover or grating so ythat rocking movement between the cover or grating and the frame is eliminated without the necessity of machining the seating faces.
A further object of the present invention is to construct a drainage frame and cover or grating of indenite length in such a manner that the frame members will be held more securely vin position against endwise movement relatively to each other. Y
Referring to the drawings:
Figures 1 and 1A are plan views of a plurality of gratings, and a frame therefor, constructed in accordance with the present invention.
Figure 2 is a section, to an enlarged scale, on
vthe une 2-2 of Figure 1.
Figures 3 and 3A are perspective views of each of the diiferent components shown in Figure 1.
Figure 4 is an enlarged fragmentary perspective View showing the coacting faces of a grating anda frame section.
In the construction illustrated, which is suit-- able for covering a long drainage channel in the `surface of an aerodrome, a plurality of rectan- .at the underside of th'e grating 5 than at the 55 top. Such an arrangement tends to .prevent choking of the openings 8. I
The gratings 5 are arranged end to end in a fixed frame I0 which is set in the ground, the upper surfaces of the gratings 5 being substantially Hush with the upper edge of the frame I0, the inner faces of which are provided with' bevelled seatings II for engagement by the faces 1 of the gratings 5, l
The frame I0 comprises a plurality of` pairs of opposed side sections I2 which are secured together end to end to suit the length of the drainage-channel to be covered. Each of these side sections I2 may be formed as a casting having a main wall I3 which is inclined outwardly in its upper portion to provide the seatingv face II aforesaid and a horizontal flange It extending outwardly from the foot of the main wall. Preferably the seating face II terminates short of the upper edge of the main wall I3. Vertical webs I5 integrally united with the main wall I3 and flange I fi are provided at the ends of the section I2 and at two or more intermediate positions to reinforce the seating face II.
The side sections I2 of the frame I0 may be equal in length to th'e gratings 5 associated therewith, and the ends of each grating 5 may be disposed iiush with those of a pair of opposed frame sections I2, or each grating may be supported partly on one pair of -frame sections and partly on the next pair.
The frame I0 is completed by end sections I6 of U shape, which are formed as single castings, the parallel limbs of each such end section being of similar construction to the side sections I2 above described, and provided with inclined seatings II for th'e associated grating 5 in like manner. rIhe parallel limbs aforesaid may be relatively short, or they may be made equal in length to the side sections as illustrated.
The frame is thus of sectional construction and has U shaped members'at its ends.
The transverse portion I'I of each end section i6 may be of plain L section, with the flange' I8 thereof directed outwardly and continuous'with the foot flanges I4 of the parallel limbs, stffening webs I9 which correspond to the webs l5 of the limbs aforesaid also being provided.
In assembling the frame Iii, the end vertical webs I5 of each side section I2 are connected to those of the adjacent sections by means of bolts 20, and the endmost side sections I2 are similarly connected to the limbs of the end sections I 6.
The frame I0 is set in concrete or otherwise secured at the edges of the drainage channel, and each side section l2 may be connected to the opposite section by one or more integral or other cross members.
These may take the form of metal plates 2l which are interposed between adjacent frame sections and held in place by the bolts Qil connecting the latter. A drainage opening may be formed between each two adjacent gratings 5, and between the end gratings and the trans- Verse portions 'i of the frame sections l5, by recessing the end ilanges of the gratings as at 22, the upper edges of the cross members 2l being in this case recessed as at 23.
To prevent tilting of the gratings 5 in a plane transverse to the frame l when under load, and also to prevent their displacement longi tudinally of the frame Ill, the coacting surfaces '5, H of the gratings 5 and frame l0 are provided with interengaging pyramidal projections, pref erably complementary in form.
Conveniently the seating surface il on each frame section is formed with a plurality oi equally spaced pyramidal teeth 24 which are triangular in plan view and whose top edges 25 are inclined downwardly towards the interior of the frame, the ends of the teeth 24 being vertical and preferably continuous with the inner face of the main wall I3 of the section. The top edges 25 of the teeth 2li, which are disposed in planes at right angles to the inner face aforesaid, may be inclined at a smaller angle than that shown, and may veven be horizont-al. The lower corners of each triangular tooth '2d may meet those of adjacent teeth, the sloping tooth sides 2li meeting the bevelled seating surface 'li in lines which preferably extend to the inner edge of the latter.
With such an arrangement, the bevelled faces l on the gratings 5 are formed with pyramidal recesses 27 which are adapted to receive, and are complementary to, the teeth '24 on the frame sections. The parts of the seating face 'l between these recesses 2l may be regarded, oi course, as pyramidal projections which interengage with those on the frame sections.
Obviously the gratings 5 above described may be replaced by, or used in conjunction with, imperforate cover plates adapted to seat in the xed frame Ill, and the seating faces of these y cover plates may be formed with recesses which correspond to the recesses 21 in the gratings 5.
Furthermore, it should be understood that, although the invention has been described with reference to aerodrome gratings, it is equally applicable to street and channel gratings.
The drainage frame and cover or grating in accordance with the present invention is a selicontained structure and when in use is not dependent upon external support from the ground to cause the parts to retain their proper relative i mediate the ends from endwise stresses such as might distort the frame and cause it to move so that the side sections at one side are no longer directly opposite to those of the other side.
