BACKGROUND OF THE INVENTION The manufacture of large cast slabs, generally cement or concrete, used in building constructions, are disclosed to be manufactured in a multiple vertical mold assembly forming a battery. It is also known to arrange the individual molds in l generally side by side relationship and to support the molds on -two parallel rails. This functions to permit accurate alignment Movable molds on carriages,which are suitable for use as .forms in the production of concrete walls, have been disclosed in Gennari utility model 1,935,741. However, the mold carriage utilized is not suitable for molds which are to be assembled as a battery.

The manufacture of plates utilizing horizontal palettes as disclosed in French Pat. specification No. 1,343,461 utilizes palettes equipped with undercarriages movable on rails to more readily supply the palettes to the different manufacturing stations. This manufacturing method necessitates a stationary installation occupying a large area which may only be moved at considerably expense.

It is an object of the present invention to provide an assembly of multiple vertical slab molds which are readily manipulated as separate molds and which may be readily assembled into a battery.

BRIEF SUMMARYv OF THE INVENTION The present invention provides an assembly of vertical slabcasting molds comprising a plurality of vertical molds assembled in side-by-side relationship, said vertical molds being positioned over at least two parallel sets of rails with each set of rails disposed on opposite sides of the centerline of said molds; each of said molds being adapted to be moved on at least two wheel assemblies, one wheel assembly being on each set of rails; each set of rails comprising at least two parallel tracks; each of said wheel assemblies being adapted to move on one track and being of a sufficiently low height that they may move under said molds; and the wheel assemblies of adjacent molds are positioned on adjacent tracks forming a staggered relationship relative to each other.

BRIEF DESCRIPTION OF THE DRAWINGS means for moving the molds;

FIG. 7 is asection of the middle portion of the battery in l perspective.

DETAILED DESCRIPTION OF THE INVENTION In the drawings, the three base support girders l support a battery 30. A fixed rear sidewall mold 2 is positioned at the back of battery 30 against back support frame 3 which is rigidly fixed to the rear of said base girders l.

Double T-section members 4 are arranged between the base girders I. Only one side girder l and the middle girder 1 are illustrated in FIGS. 2 and 3. The double T-section members 4 have a wide bottom flange 4a serving as a support surface with the upright section 4b joining the upper narrow flange 4c.

Track rails

5 and 6 are supported on the wide flange 4a.

Rollers

7 and 8 of

wheel assemblies

9 and 10 are mounted on

track rails

5 and 6 respectively.

The wheel assemblies support and move the sidewall mold l1. Each sidewall mold 11 contains vertical hollow plates and forms the sidewalls of two slabs being cast, one on each side of mold ll. Vibrating elements 25 or heating elements 26 are positioned in the hollow spaces between the two sidewalls forming the mold element or in recesses in the sidewalls of the mold element l1 so that the walls are effective either as vibrating walls 11n or as heating walls 11H. The sidewalls may each be equipped with vibrating devices or with heating devices or with a combination of both. The vibrating elements 25 and/or the heater elements 26 are positioned to be accessible from above or from the end of the sidewall mold 1I.

Each sidewall mold 11 is equipped withat least two wheel assemblies, each of which has two rollers. In the embodiment illustrated in the drawings, wheel assembly 9 consists of two

U-section rails

27 and 28 mounted on roller 7. Wheel assembly 10 is similarly mounted on roller 8.

With particular reference to FIGS. 2, 3 and 4, the drawings illustrate the arrangement of adjacent wheel assemblies 9 and l0, which support adjacent sidewall molds 1l" and 11, in a staggered relationship. The heighth of the wheel assembly may be varied by insertion of shims 12 (FIG. 4). The height is adjusted so that the wheel assemblies can be moved beneath the adjacent mold elements, for example mold element 11R. lt is possible to provide suicient stability to each sidewall element 1l by appropriate spacing l (in FIG. 5) ofthe wheels.

The lower inwardly disposed flanges 13 and I4 of

wheel assemblies

9 and 10 respectively are positioned beneath the upper flange 4c of the .double T-section member 4. The

flanges

13 and 14 act as supports which safeguard the sidewall molds l1 against tilting when subjected to relatively large lateral forces, for example those produced by gusts of wind. These

flanges

13 and 14 also function to guide the sidewall mold 11 along the upright member 4b. Optionally, separate guide rollers may be provided for this purpose.

The edge walls 15 which define the periphery of the slab mold may be fixed on the sidewall molds Il and/or on the wheel assemblies 9 and l0, or may also be loosely inserted between adjacent sidewall molds ll. The fastening of the bottom edge wall 1S and the end edge walls 15 to the sidewalls 11 or to the

wheel assemblies

9 or 10 has the advantage that the completed cast concrete slabs can be moved together with the sidewall molds 11, and thus the battery or a portion thereof may be withdrawn as a unit.

The bracing of all the sidewall molds l1 and l5 is effected by pressure forces which are transmitted by the base girders l and by the tie rods 16 arranged near the upper edge of the battery of molds. The tie rods 16 are pivotally mounted on the fixed back mold 2. When the molds are sufficiently large to cast long concrete slabs, other tie rods may also be used, for example tie rod 17, illustrated in FIG. 2.

Front sidewall mold 18 is also provided with wheel assemblies such as those provided for sidewall molds ll, and is constructed to function as a stable pressure plate for transmitting the forces supporting and bracing the battery of sidewall molds.

Hydraulic means 19 and 20 are arranged on front mold 2 as illustrated in FIGS. 1, 2 and 6 to provide the pressure to brace the molds. Optionally, they may be positioned on back mold 2.

To move and separate sidewall molds 11 quickly, the lower hydraulic means 20 are supported on countersupports 2l which may be pivoted laterally so that the molds 11 may move over them.

Mold elements 11 are attached to and removed by chain 22 which is driven by chain winch 23.

The construction of the present invention provides an assembly of vertical molds of relatively economic construction. This is accomplished utilizing supporting and pressure application means which are not of complicated design and manufacture.
