Cl. 249-189 5 Claims ABSTRACT OF THE DISCLOSURE A support and carrier for a mould for poured concrete; the moulding element being connected to a plurality of cranks spaced along its length and actuated by a single actuator for moving the moulding element toward and away from an operative position.

This is a continuation-in-part of application Ser. No. 472,875, filed July 19, 1965, now abandoned.

This invention relates to a carrier and support for a mould for the manufacture of a concrete skeleton for a building.

When manufacturing a concrete skeleton for a building it is known to make use of a mould formed from steel or other metal into which concrete is poured. This enables the concrete skeleton to be cast in a short time. There is, however, the problem of the easy release of the mould from the cast concrete skeleton.

The invention aims at solving this problem by pro viding a mould carrier and support construction, which can easily and quickly be released from the cast con crete skeleton.

This object is realized, according to the invention, by providing a particular mould carrier frame. A moulding element is connected with the frame and is movable between a non-operative position and anoperative position. At least one carrier frame and one moulding element are provided. The single moulding element can be designed to be self suflicient for holding poured concrete until it hardens and then for releasing same.

Alternatively, two carrier frames each carrying a moulding element can be positioned such that the moulding elements, when moved to their operative positions, will together form a mould into which concrete can be poured.

In use, the carrier frame of the mould is first adjusted to the proper position after which the moulding element is moved to the operative position. The concrete is then poured and allowed to set. Subsequently, the moulding element is brought back to its non-operative position to release the concrete skeleton. The whole mould structure, carrier and support can then be removed from the concrete skeleton ready for reuse at another location.

According to a preferred embodiment of the invention the moulding element is moved with the aid of an eccentric mechanism which parallely moves the moulding element. This eccentric mechanism is formed from a plurality of crank arms connected by a linking bar to an actuating rod movable between two positions.

The invention will now be further apparent from the following description with reference to the accompaying drawings which show, by way of example only, one embodiment of the invention.

In the drawings:

FIGURE 1 is a diagrammatic side elevation of a mould carrier and support according to the invention, with the moulding element in the non-operative position;

FIGURE 2 shows the device of FIGURE 1 in the operative position.

Refer to the drawings which illustrates one embodiment of the invention. The carrier frame 1 has a moulding element 2 connected therewith which is movable by a means to be described between a non-operative position illus trated in solid lines and an operative position illustrated in phantom. In the non-operative position of the moulding element 2, the whole mould can be easily transported and set in position after which the moulding element 2 is moved to its operative position, in which it constitutes the moulding surface of the mould.

For support of the moulding element a screw jack 3 is affixed to the carrier frame 1, by means 3a. The jack is adjustable in position with respect to a reference plane 4. If the jack extends upward, its adjustability permits skeleton elements to be moulded at various heights, whereby a structure of greater height than moulding element 2 may be formed.

The motion mechanism for the moulding element is an eccentric mechanism giving a displacement Y of the moulding element in its longitudinal direction and a displacement X perpendicular to its longitudinal directon. These displacements are indicated in FIGURE 1. In FIGURE 1, moulding element 2 is shown in the nonoperative position. In order to have the moulding element, while moving, remain perpendicular to reference plane 4, a number of eccentrics are arranged over the length of the moulding element, said eccentrics being actuated simultaneously with the main eccentric by means of an actuating rod 5 which is pivotally connected at 5a to a linking bar 6. Bar 6 is pivotally connected at 6:: to rods 7. As shown in the figures actuating rod 5 is an extension of one of the rods 7. However, rod 5 may be separate and separately pivoted at the end thereof opopsite the end which is moved between the stop positions 8, 9. Rods 7 are fixedly connected at points 7a to rods 10. Rods 7, 10 and bar 6 comprise a plurality of cranks. Points 7a are pivot positions for the cranks and are secured to carrier frame 1 by flanges 11. Rods 10 are connected at pivots 12 to moulding element 2.

For the actuating rod 5 the stops 8 and 9 have been arranged on the carrier frame, which determine the nonoperative position and the operative position of the moulding element 2, respectively.

In FIGURE 1, with the moulding element 2 in the nonoperative position against stop 8, pivots 12 are at position A. Turning to FIGURE 2 when handle 5 is moved against stop 9, this moves bar 6 axially, which moves rods 7, 10 about their pivots 7a and shifts pivots 12 to positions B, whereby the moulding element 2 is moved to its operative position.

After concrete has been poured into the mould and has set, the actuating rod 5 is moved against stop 8, bar 6 is again moved axially, thereby pivoting cranks 7, 10 about their pivots 7a, which returns pivots 12 to position A. The moulding element 2 returns from its operative position, shown in phantom in FIGURE 1 and in solid lines in frame 2, to its non-operative position. This releases it from the set concrete.

During movement of rod 5 toward both of stops 8 and 9, the moulding element continues to be aimed in the same direction, which can be as illustrated in FIGURE 1, perpendicular to plane 4.

Release of the moulding element from the set concrete while the moulding element remains perpendicular to reference plane 4 assures a clean separation of mould and concrete without undue stress or torque forces.

In an alternative embodiment, as shown in FIGURE 1, the moulding element '2 may not be self sufficient, and two cooperating moulding elements would be brought together to form a mould. The carriers for these elements 3 would be so positioned that when both moulding elements 2 are moved into their operative positions, they are together so as to form a complete mould. If both moulding elements 2 are separated from the set concrete simultaneously, the stresses on both sides of the completed moulded structure will balance.

The mould for the manufacture of a concrete skeleton for a building is advantageously usable with a methOd for the industrial house-building, as described in United States patent application Ser. No. 472,876, filed July 19, 1965, by Adriaan Leyton for Method of Building, and assigned to the assignee hereof, and now abandoned.

Although there has been described preferred embodiments of this novel invention, many variations and modifications will now be apparent to those skilled in the art. Therefore, this invention is to be limited, not by the specific disclosure herein, but only by the appending claims.

The embodiment of the invention in which an exclusive privilege or property is claimed are defined as follows:

a linking bar;

a plurality of cranks each having a first end pivotally connected to said moulding element; said cranks each having an intermediate portion pivotally connected to said frame; said cranks each having a second end pivotally connected at diiferent positions along said common linking bar, whereby movement of said common linking bar axially moves each said second end of each said crank to the same extent;

an actuating rod connected with said common linking bar for axially moving same, whereby movement of said actuating rod in one direction moves said moulding element into an operative extended position and movement of said rod in the opposite direction moves said moulding element to a non-operative retracted position;

each of said cranks being comprised of an element having said first and second ends and having a position intermediate said first and said second ends about which said element is pivoted, and

a pivot and a support therefor to which said position of each of said elements is secured; said pivot support being connected to said carrier frame.
