Description
T. D. ANDERSON ADJUSTABLE TIE ROD FOR CONCRETE WALL FORMS Feb. 21, 1933.
Filed July 24 1950 Patented Feb. 21 1933 PATENT OFFICE TED D. ANDERSON, OF BATTLE CREEK, MICHIGAN ADJUSTABLE TIE-ROD FOR CONCRETE WALL FORMS The present invention pertains to a novel adjustable tie-rod of a type particularly adapted for securing concrete wall forms in m their proper spaced relation in order that they may receive the concrete and hold it until such time as it has become set.
The primary object of the present invention is to devise a tie-rod for securing concrete wall forms together which may be adjusted to accommodate the spacing of the wall forms at various distances apart in order to obtain various wall thicknesses. The ties are stamped out of sheet metal and constructed in two units, each having means for 15 engaging the studs which are located outside the planks comprising the wall form or mould and each of the sections having interlocking parts for securing them together, the
V interlocking parts being so constructed that the sections may be'adjusted to various overall lengths.
With the above and other ends in view the invention consists in the matters hereinafter M set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure 1 is a transverse cross sectional view of a concrete wall form secured together by means of the present tie-rod;
Fig. 2 is a fragmentary side elevation illustrating the positioning of the studs;
Fig. 3 is a perspective view of the clip which is used to secure the form planks to the r studs where the tie-rods are not used;
'35 Fig. 4 is a fragmentary perspective view of the male unit of the present tie-rod;
Fig. 5 is a fragmentary perspective view of the female unit;
, e Fig. 6 is a fragmentary cross sectional plan 4 through one of the studs with the tie-rod in lacep Fig. 7 is a fragmentary side elevation, partly in cross section, of a modified form of stud, and
Fig. 8 is a cross sectional plan of the latter stud receiving the tie rod.
Like characters of reference are employed throughout to designate the corresponding arts.

face upon which vertical studs 2 are arranged, the studs being provided with holes 3 to accommodate nails in order that suitable bracing may be employed to hold the studs vertical. Each stud is provided with key-hole slots 4 which are spaced apart a distance corresponding to the planks 5 which comprise the wall form or mould into whic the concrete is poured.
To secure the planks or boards 5 to the studs there is provided a clip as illustrated in Fig.3 which is formed as a stamping from sheet metal. The enlarged retainer portion is inserted through the enlarged part of the key hole slotand is allowed to fall into the narrow portion of the slot so that the shoulders 7 engage the stud to prevent removal of the clip from the slot. The flat body portion indicated at 8 lies upon the top of the adjacent plank 5- and has a pair of depending fingers 9 which engage the face of the plank which is remote from the stud, thereby holding the plank against the stud. An upwardly projecting finger 10 is also provided to engage the face of the plank which is placed on top of the clip and in this manner the fingers 9 and 10 hold the top of one plank and the bottom of the next one close to the stud into which the clip is secured.
By employing studs, planks and clips and associating them in the manner described above panels are constructed as clearly illustrated in Fig. 1 and it is necessary that these panels should be secured in definite spaced relation in order that the concrete poured in the form thus assembled may be of a determined wall thickness. The present invention therefore provides a novel tie-rod to secure these panels in definite spaced relation.
' The tie-rod is formed in two sections indicated as 11 and 12, the section 11 being a male member and the section 12 being a female member. Each section has an enlarged head 13 which is adaptedto be inserted-through keyhole slots 4 and each section has a narrow neck portion 14 which slips into the small portion of the key hole slots ,4 sothat the head 13 prevents removal of the sections from the stud.
The body portions of the sections-11. and 12 are formed by stamping channel members out of sheet metal of suitable dimensions so that the member 13 is inserted within the section 11. The section 12 is provided with a series of definitely spaced perforations 15 and the section 11 is provided with correspondingly shaped and spaced inwardly projecting stamped portions 16. The channel member 12 cannot, therefore, be inserted within the channel 11 without the stamped portions 16 entering the recesses 15 and when they are in this position longitudinal movement of the two sections 11 and 12 relative to each other is positively prevented.
It is apparent that by equally spacing the recesses 15 and projecting portions 16 that it does not matter what longitudinal relation the two sections 11 and 12 are placed in for as long as some of the projecting portions engage recesses the two sections cannot be moved longitudinally relative to each other. The tie-rod is therefore adjustable as to length and same sized tie-rod can be adjusted to tie forms together at various spaced relation.
In Figures 7 and 8 there is illustrated a modified form of stud which is constructed by securing a pair of angle members 17 together by rivets 18, spacers 19 being placed between the angle members to maintain them in a spaced relation so that they receive the ends of the sections of the tie-rods. In this form the tie-rod is turned sideways so that the head 13 passes between the angle members and when turned flat the head engages the angle members as clearly illustrated in Fig. 8, thereby preventing its withdrawal therefrom.
Although specific embodiments of the present invention have been illustrated and described, it is to be understood that various alterations may be made in the details of construction without departing from the spirit of the invention, and such changes are contemplated.
What I claim is -1. An adjustable tie-rod comprising a-pair of channel members adapted to fit one within the other, and interlocking recesses and projecting portions formed in the angles on re spective members to prevent longitudinal movement of said channel members relative to eachother when one section is inserted within the other.
2. An adjustable tie-rod comprising a pair of channel members fitting one Within the other, recesses formed in the angles of the inner channel member, and inwardly projecting portions formed in the angles ofthe outside member and adapted to fit into said recesses.
3. An adjustable tie-rod comprising a channel member, a series of recesses formed in the corners of saidchannel member, a channel member adapted to be received on said first named channel member, and indentations formed in the corners of said last named channel members and adapted to nest in said recesses.
4. An adjustable tie-rod comprising a channel member, a series of recesses formed in the corners of said channel member, a channel member adapted to 'be received on said first named channel member, indentations formed in the corners of said last named channel members and'adapted to nest in said recesses, and means carried by each of said channel members for attaching the same to a form board.
In testimony whereof I affix my signature.
TED D. ANDERSON.
