Usually, the terminal portions 18a, 19a of the clip ends 18, 19 are flared away from the structural element to facilitate the physical passing of the ends about the lower flange 11 of an I-beam or like portion of other In Fig. 3 is shown a modification of my invention and like parts are designate by like reference characters; however, the body spacing elements 20 are of substantially circular contour as compared with the arcuate contour illustrated in Fig. 1. Also, the end portions designated 22 in Fig. extend uprightly in contact with the side faces of the lower flange 11 and are bent downwardly toward and into contact w1th the flange web at the ends 22a.

Preferably, also, my re-enforcement embodies a form spacer element for spacing the mold'boards and in this instance, thebottom mold boa-rd 15a, as shown in Fig. 4. The

general re-enforcement construction including its cllp ends as illustrated in Fig. scorresponds to Fig. 1 and like parts are des-' ignated by like reference characters; However, the form spacers 23 shown as extensions of the wire or other stock of the respective clip end portions 18a, 19a, are bent rearwardly in an appropriate manner as is indicated in Fig. 5.

be similarly formed for the other parts of the mold. 1 7

In the modification of my invention shown Fig. 6, is of pro-formed clip construction, the opposite end 24 being arranged for manual bending'of the same about the lower flange of an I-beam or equivalent part of other structural elements. The intermediate body spacers 20 are of any desired contour Such form of my clip may embody the form spacer extens1on 23, slm harly as in Figs. 4 and 5. This figure alsoshows the re-enforcement interconnecting wire 21 located above and welded to the respective individual re-enforcements.

In multiple unit form of my invention shown in Fig. 6, the alternate units may have Form spacer extensions the clip ends and manually bent ends arranged in alternate. I

In the form of my invention illustrated in Fig. '7, the re-enforcement interconnecting wire 21 is weldedor otherwise secured to the staggered re-enforcement elements 25, the

particular elements being selected as desired, that is to say, whether or not with interme diate resilient body spacer portions 20 and whether or not with the clip end terminal portions 27 or whether or not with the form spacer elements, similarly as .above illuss trated in' Fig. 6 at 23. By providing for such staggered relation for the successive oppositely disposed re-enforcement elements, the respective wires are located advanta- 1 geously to enable the workmen to clip the same at the desired locations of re-enf-orcement when of clipped form or to manually bend the same when of manually bent form. Such constructionof my invention enables the multiple units to be readily packed at the location ofmanufacture and readily handled and installed at the'location of use.

In the particular form of my invention illustrated in Fig. 7, the same is formed of the resilient body spacer'20 corresponding to that in Fig. 1, which may be modified t0 the form illustrated in Fig.3 or that illustrated in Fig. 6; the terminal portion 27 may be of the self-clippingtype.

AS is illustrated inFig. e, as steel buildings of modern construction, such channels are usually employed in the exposed walls of the building, that is to say, the web 31 of the channel 30 is disposed in substantially vertical position.

In the arrangement of my clip type of'reenforcement, shown in'Figs. v8 and 9, the ter minal clip 32 coacts with the resilient body spacer 3t in the application of the clip end about the lower flange 35 of the illustrated channel-30. In a similar manner, the 're-en- I f-orcement 33 may be provided at its opposite end with .a similar clip formation for the upper flange 36 of the illustrated channel 30.

As illustrated in Fig. 8, the upper end of the re-enforcement 33 is unformed for application about the upper flange 36, and after application of the lower clip 32, the upper terminalportion 37 may be bent manually about the upper flange 36 as is indicated in dot and dash outline at 37 a.

Such re-enforcement construction having single or double clip end formations are pref- 'i-go erab-ly marketed in the form of multiple units connected at predetermined spaced distances from one another by means of the re-enforcement connecting wire 38, as is illustrated in Fig. 9,eithe r centrally or at any other suitable location on the individual re-enforcements. I

My clip illustrated in Fig.8 also preferably embodies a formspacer extension of the type illustrated at 40, formed for example byfbending back the :i-Wire stock-: UPOIl'iTltSBlf as appears in edge view in Fig.2
