METHOD OF AND APPARATUS FOR CONSTRUCTING WALIIS.

Application filed April 13.

To all whom it may concern: I Be it known that I, CHRISTIAN BRYNOLDT,

a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Methods of and Apparatus for Constructing Walls, of which the following is a specification.

This invention relates toan improved method of and apparatusfor constructing sea and other walls and the like, from material such as concrete.

One of the primary objects of my invention is the provision of an improved method whereby the construction of such walls may be carried out more quickly and economically and with less form equipment.

Another object of my invention is the provision of an improved form which is collapsible and telescopic outside other forms in place, the forms being so constructed that a new form can be set up without disturbing the form or forms next to it.

Still another ob'ect of the invention re-- sides in the provision of an improved traveler having novel means for supporting the form sections.

My invention also contemplates the provision of form sections so arranged that each form is in effect self sustaining sothat only one traveler mechanism is needed for a number of forms.

The foregoing, together with such other objects as may hereinafter appear, or are incident to my invention I obtain by means of a method and apparatus, illustrated in the preferred form in the accompanying drawings wherein:

Fig. 1 is anend elevation of my improved traveler with the form sections in place; Fig. 2 is a fragmentary side elevation, drawn on an enlarged scale, of that portion of the device shown opposite the line 2--2 of Fig. 1; Fig. 3 is a rear elevation of Fig. 1; Fig. 4 is a plan view of Fig. 3; Fig. 5 is a side elevation of a portion of the rear or back section of .the form, drawn on an 50 enlarged scale; Fig. 6 is a fragmentary lan v view of portions of the rear and front orm sections; Fig. 7 is a section taken on the line 7-7 of Fig. '5; Fig. 8 is an elevation of a detail of my improvements; Fig. 9 is a 1920. Serial No. 373,531.

'14 and 15 are enlarged sectional views illustrating details of my improvement, Figs. 16, 17 and 18 illustrate a modification of my invention.

Referring first to the improvements in the apparatus for constructing walls, it will be seen that I employ a traveler, in- A cated as a whole by the reference letter which is of the. eneral type shown and generically claime in my Patent No. 1,298,450, issued 3/25/19. This traveler fundamentally consists of an inverted or 'U-shaped frame, the side and top members of which are preferably composed. of structural steel members arranged in the form of trusses suitably braced, the side frames being provided with Wheels 7 riding on rails 8, sup orted in any preferred manner, as by the oundation or base 9 of the wall. The traveler thus straddles the work and is mounted for movement longitudinally thereof. ../The details of the The wall form consists of a back form section B; a front form section 0; a detachabletop frame D for securing the form sections together when in place; and the bulkheads closing the ends of the forms, such bulkheads also being detachable as will further appear.

The construction of the back wall mold section is illustrated in Figs. 3 and 5, from inspection of which it will be seen that such section is a unit comprising a plurality of sheetmetal plates 10, all ofwhich, with the exception of the plate at one end of the section, have an angle 11 at one vertical edge and an angle 12 at the opposite vertical edge; and a pluralit of angles 13 extending longitudinall o the form andriveted in place. tion has an angle 11 at each vertical edge. A plurality of strong backs or whalers 14 extend longitudinally of the whole section and serve to bind it into a more or less rigid unit. The angles 11 project above the top edge of the section to provide a.

traveler wheels are shown in Figs. 2, 8 and The p ate at one end of the-secmeans for attaching the frame B. At the bottom the section is provided with a Whaler 15.

The front section C is similarly constructed but is specially shaped in order to give the desired curvature to the front face 1 the required width of wall, and to inopera ported by tive position away from the wall for telescoping after the concrete has sufficiently set. It will, of course, be understood that the acks 16 serve to lift the wall form sections in order to permit of collapsing and shifting.

The wall form section C is further supmeans of the

jacks

20 and 21 exetween the section and the outer leg of the traveler. The frame D is secured to the top of one of the wall form sections, preferab y the section C.

When the wall sections have been positioned by means of the mechanism just described, the top frame D will be brought into a position for bolting to the section B. Such frame consists of a plurality of cross struts 22, the ends of which are adapted to be secured to gusset plates 23 on the upwardly projecting portions of the angles 11; and the longitudinal bracing angles '24 (see Figs. 3, 5, 6, and 7). The frame D therefore serves to secure the wall form sections against spreading and, if desired, additional means, such as the tie rods 25, may be employed. Adjustment of the sections as to width is permitted by virtue of the holes in the struts 22.

tending The bulkheads E comprise a suitable frame work 26 secured to the inner face of which, adjacent the vertical edges, are the channels 27, the purpose of which will further appear. Lagging 28 is secured to the bulkhead frames.

The channels 27 are adapted to be secured to the vertical end angles of the wall form sections as shown in Fig. 14: and they thus cooperate with the form sections to mold the wall. They are, therefore, in fact a detachable section of the wall form, and when detached an adjacent form may be lapped over that portion of the wall molded by the channels 27, the utility of which will be further set forth.

Returning now to in improved method of constructing the wal s, heretofore it has been customary in this art to construct secuseaeae tions of the wall with gaps therebetween,

such gaps being cast a few days later. This method involves stretching out the work over a considerable distance and also requires a large amount of form material. I propose to cast the intermediate sections practically immediately after the spaced sections have been cast and while the concrete is still too green to stand the wash of the waves and forms are, therefore, still in place while the concrete is still green. In car ing out the method I remove the bulkhea s E and the channels 27, and attach to the'ends of the form sections for the intermediate section of wall to be cast, angles 29, by means of bolts 30, the free legs of such angles being of such a length as to overlap the exposed portions of the adjacent sections of the wall already cast, as shown in Fig. 15. I then cast the intermediate section, repeating the operation as many times as is necessary for the length of wall to be constructed.

It will be noted that the form for the intermediate sections can be readily brought in place without interference with the form sections already in place because the forms can be collapsed on the traveler a distance sufii cient to clear the forms already in place. Similarly, after an intermediate section of the wall has been cast, I am enabled to remove the form sections for that portion of the wall already cast when such portions of the wall has sufliciently set, leaving the form sections in place about the green sections of the wall. I am thus enabled to keep the Work much less strung out and effect a considerable saving in time, labor and form equipment, as will be clear from the fact that it is possible by this nfethod to keep a relatively smaller number of forms practically continuously in use over a relatively shorter length of wall. The operations are further facilitated by virtue of the fact that each form when all of the parts are in place, is practically self sustaining, which frees the traveler for the setting up of new forms in place or the shifting of old forms to a new point of use.

In Figs. 16 to 18, I have shown an adaptation of the foregoing apparatus to the construction of a wall which is provided with laterally projecting brackets. The traveler in this instance is substantially the same as that previously described with the exception that it is provided With an overhead mixing floor 31 which supports a mixer 32, the traveler being further provided on one side with rails 33 for a hoist-ing car or elevator mechanism 34, such rails being supported in a frame 35 braced overhead by means of a frame 36 extending to and connected with the upwardly projecting portions of the far leg of the traveler. The car 34 is elevated by means of the hoisting cables 37 and when it reaches the upper limit of its travel, it is tilted in the manner indicated in dotted lines so as to discharge directly into the mixer 32. p

The wall form sections B and C may be constructed in any referred manner, such as that already set. fiirth. The brackets are formed by means of the bracket forms C secured to the form section C. The section B is collapsed for telescoping by means of the jacks 38 and 39, by which it is also supported in operative position, and the section C with its bracket mold C'is supported for collapse and telescoping by the jacks 40 and 41, there being suflicient clearance to free the form from the brackets on the wall.

I claim: 1. The herein described process of constructing sea walls and the like from plastic material such..as concrete which consists in in removing casting a section with a form,
