2 Claims.
The present invention relates to new and useful improvements in screed supports for use in concrete work and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arrangement of parts whereby said device may be expeditiously and accurately adjusted as desired.
Another very important object of the invention is to provide a screed support of the aforementioned character which will permit the development of a plane or curved concrete surface.
Other objects of the invention are to provide an adjustable screed support of the character described which will be comparatively simple in construction, strong, durable, highly eiicient and reliable in use, comp-act and which may be manufactured at low cost.l
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a cross sectional view through a portion of a form with the concrete thereon, showing a screed support constructed in accordance with the present invention installed.
Figure 2 is a vertical sectional view, taken substantially on the line 2-2 of Fig. 1.
Figure 3 is a vertical sectional view, taken sub stantially on the line 3 3 of Fig. 1 but showing a screed in use.
Figure 4 is a View in side elevation of the invention, the T bar being shown in cross section.
Figure 5 is a top plan view of the invention.
Figure 6 is a detail view in top plan of the bar receiving arm.
Referring now to the drawings in detail, it will be seen that the reference numeral I designates generally a portion of a form.` The form work I comprises, as usual, the sheeting 2 mounted on horizontal joists 3, etc. The reference numeral 4 designates concrete on the form I.
The embodiment of the present invention which has been illustrated comprises an angular metallic bracket 5 which is firmly secured in position` on one of the joists 3 of the form work I in any suitable manner, as by nailing. Theadedly mounted for vertical adjustment in the bracket 5 is a removable supporting rod or post 6. On its upper end, the post 6 is provided with a head l. In spaced relation below the head I, a collar 8 is provided on the post 6.
193s, serial No. 196,501
(ci. 'v2- 122) On the upper portion of the post 6 and confined between the head 'I and the collar 8 is an arm 9 which terminates in an upturned free end portion I0 having formed therein a vertical slot I I. The arm 9 is further provided with an opening I2 the purpose of which will be presently set forth. The slot II is for the reception of the depending portion of a metallic T bar I3.
It is thought that the manner of using the invention will be readily apparent from a consideration of the foregoing. The first step is to nail or otherwise secure the brackets 5 in the desired position on any convenient portion of the form work, such as the joist 3 in the manner shown to advantage in Fig. 1 of the drawings. The elevation at which the bracket 5 should be secured varies in accordance with the thickness of the concrete. An opening is then drilled in the form sheeting 2 through which the post 6 is inserted to be threadedly engaged in the opening which is provided therefor in the bracket 5. After enough of the posts 6 have been mounted in positionin this manner the T bar I3 is mounted in the alined slots II of the arms 9. As indicated in Figs. 2 and 3 of the drawings, two rows of the posts 6 are erected in the manner for supporting two of the T bars I3 in spaced parallelism. In practice, it has been found advisable to mount the T bars I3 approximately one-quarter of an inch higher than the theoretical grade of the concrete as the formsI to which the supports are attached usually settle. After a suiiicient quantity of concerte has been placed on the form I the threaded posts 6 are adjusted vertically in the brackets 5 in a manner to bring the T bars I3 to the desired grade, either up or down. 'I'he posts 6 may be conveniently adjusted by simply applying a wrench or other tool to the heads I of said posts. Aftera few feet of the T barsy I3 have been brought to the desired grade, the concrete can be screeded to an exact surface. In Fig. 3 of the drawings, the reference numeral I4 designates a conventional hand screed. After the screeding operation has been completed the T bars I3 are removed, also the posts 6. The openings left by these removals are then gone over by the finishers in the usual manner. By inserting wire through the openings I2 in the arms 9 the T bars I3 may be secured tightly in position. This is particularly desirable when. a curve or crown is to be put in the T bars I3. The construction and arrangement is such that the T bars I3 may be sprung to any desired curvature. A crown or vertical curve may also be put in the screed.
It is believed that the many advantages of an adjustable screed support constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
1. A screed support comprising a vertically adjustable post, spaced enlargements on the upper portion of said post, an arm mounted for swinging movement in a horizontal plane on the post between the enlargements, said arm having a.
15 vertical slot in its free end portion, and a T bar removably mounted on the arm and engaged in the slot.
2. A screed support of the class described comprislng a bracket mounted on a support, a post threadedly mounted for vertical adjustment in said bracket, a head on the upper end of said post, a collar on the post in spaced relation below the head, an arm journalled on the post between the head and the collar for swinging movement in a horizontal plane, said arm having a vertical slot in its free end portion, and a T bar removably mounted on the arm and including a depending portion engaged in the slot.
