Description

Apparatus for controlling locking mechanisms in a form forming a formwork for concrete, in particular for aerated concrete

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for controlling blocking mechanisms in a formwork for concrete, in particular aerated concrete, the block-shaped form being open upwardly and provided with swinging side walls which are provided with blocking mechanisms which essentially consist of a pin on the front sidewall projecting to the side that snaps into picking the associated bolt.

BACKGROUND OF THE INVENTION

A formwork-forming form is known, in which the side walls pivoted upwardly are manually locked to form the formwork prior to being filled with the gypsum crumb. After the formation of the gas concrete cake in the maturing process, the mold is manually unblocked. The side walls are folded back hydraulically so that the gas-concrete cake can be split into smaller blocks for further processing, if necessary at a second workstation.

The bottom of the mold is preferably movable on conveying means, in particular on parallel arranged rows of rollers, on which the conveying of the mold is carried out between at least two workplaces to form a gasconcrete that can be used on site.

The locking mechanisms always consist of a resiliently loaded bolt which is rotatably mounted on the longitudinal side walls and which is provided with a recess, and a pivot located at a lateral side wall which protrudes laterally and which is adapted to the shape of the recess of the bolt. The removal is also carried out in such a way that the pin retains additionally by means of a retaining bevel.

Owing to the particular embodiment of the locking mechanisms on the side walls of the mold, manual unlocking of the locking mechanisms on the side walls is associated with an enormous effort. Since, in addition, the swelling resulting from the maturation process exerts a strong pressure on the side walls inside the reinforcing gas-concrete cake, and this pressure is essentially transmitted to the locking mechanism, the unlocking is only possible with the greatest force.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a device for controlling locking mechanisms on a concrete mold, in particular for a reinforced concrete mold, having a suitable arrangement and having suitable controls for fastening and unlocking the side walls quickly and safely. .

SUMMARY OF THE INVENTION

This object is fulfilled by a device for controlling the blocking mechanisms in the formwork for concrete, in particular for aerated concrete, the block-shaped form being open upwards and equipped with swinging side walls, which are equipped with locking mechanisms which essentially consist of a pin on the front sidewall projecting to the side which engages in the removal of the associated bolt according to the invention, which is characterized in that a suspended structure is provided on which a locking device is arranged and in particular a structurally unlocking device connected thereto, which can be placed above the mold and contain working means, which control the locking mechanisms.

The working means of the locking device is arranged in each case in the region of the shuttering corner between two side walls arranged perpendicular to one another.

The operating means of the locking device are arranged in the inner mold part, preferably at an angle of about 45 degrees to the vertical.

The working means preferably comprise a hydraulic sliding part which is connected to the sliding element.

The operating means of the locking device are always provided with at least one element for locking the locking device and at least one element for perpendicularly holding the respective side wall, in particular the longitudinal side wall.

The unlocking device is provided with working means, each of which at least one element is adapted to unlock the locking mechanism and at least one element for tilting the side wall.

The locking device is connected to at least one side wall pivoting device.

The side wall pivoting device consists essentially of a pivoting arm movable by a controllable actuating element. The control element is preferably located next to the side wall in the rolling part of the bottom. When the pivotally mounted side wall is deflected, the actuating element is preferably connected to the associated side wall by means of at least one support roller at the other end of the pivot arm.

The connections between the interlocking device or the unlocking device and the side wall pivoting devices are made by signal lines between which the control unit is connected.

The invention not only provides the possibility of simply replacing the manual operation of the locking mechanisms and the side walls with the device according to the invention, but also the possibility of faster and less demanding locking and unlocking of the mold associated with significantly higher safety and reliability.

Further advantageous embodiments are set forth in the dependent claims.

At least two latches 82, 83 and 84, 85 are arranged on the longitudinal side walls 61 and 62 in the region of their upper edges 80 and 81, each extending laterally outwards.

In FIG. 3 shows a side view of the locking device 1 according to the invention, in particular the working means 16 and 17, and the mold 63 placed on the workstation. Of the longitudinal side walls 61 and 62 arranged in the final formwork form, a side view of FIG. 3 shows a second longitudinal side wall 62 in the foreground. Symmetrically to the median plane 92, the two working means 16 and 17 are arranged in the formwork corners between the two front side walls 88 and 89 and the second longitudinal side wall 62. The pivoting device 71 supporting the second longitudinal side wall 62 is not shown for clarity. The bottom 14 rests on two rows of rollers 66, 67, on which the mold 63 can be moved to another workstation after being filled with gas-concrete pulp. The row of rollers 66 is shown in FIG. 3 covered.

At the bottom 14 and the second longitudinal side wall 62 are located both bearings 93, 94, in which the pivot axis 65 of the pivotable second longitudinal side wall 62 is mounted. Each of the other side walls 61, 88, 89 is provided with such equally formed bearings at a height. The front side walls 88 and 89, via the pivoting devices 90, 91, are each pivoted from the outside in contact with the support roller 95, 96. The support rollers 95, 96 are supported on respective pivoting arms 97, 98, which are controlled by the control elements 99, 100 of the respective holding devices 101, 102.

On the second longitudinal side wall 62, in the region of the upper edge 81, at each side at the shorter edge of the second longitudinal side wall 62, resiliently loaded bolts 83 and 85 are arranged, facing the front side walls 88 and 89 and rotatably mounted on the bearing pins 103 and 104. in the bolts 83, 85, in which the respective bearing pin 103, 104 is mounted, it can advantageously be designed as a longitudinal opening, which increases the mobility of the bolts 83 and 85.

Between the bearing pins 103, 104 and at the end of the barriers 83 and 85 facing the central plane 92 of the second longitudinal side wall 62 there is always a spring 105,106 whose force acts against the compressive forces exerted by the swelling of the concrete. These springs 105, 106 may be arranged both inside and outside the bolts 83, 85.

The other end of the bolt 85 projects beyond the short edge of the second longitudinal side wall 62 and is claw-like. The claw has a recess 107 which is open in a downward taper and to the second longitudinal side wall 62. Directly at the end of the bolt 85 is an inclined bevel 108, inclined downwardly and to the second longitudinal side wall 62. on the opposite first end wall 88 there is a locking pin 109 which projects laterally and whose upward position in the pivoted state of the second end wall 89 corresponds to the recess position 107. The resiliently loaded bolt and the respective locking pin 109 form the locking mechanism 110. an opposing, short edge of the second longitudinal side wall 62 is provided with a further locking mechanism 111 belonging to the second longitudinal side wall 62.

The locking of the pivoting side walls with the axes of rotation arranged perpendicular to each other by means of the device according to the invention is carried out as follows.

When the second front side wall 89 is pivoted upward, the locking bolt 109 arranged on it sideways encounters a leading chamfer 108 of the bolt 85. Thus, the bolt 85 pivotally mounted on the receiving pin 104 pivots upward. Upon further pivoting of the second front side wall 89 upwards and after engaging the longitudinal side walls 61, 62, the locking bolt 109 engages into the recess 107.

By actuating the lever arm 47 by the actuator element 43, wherein the end of the lever arm 47 provided with a roller is pressed against the end of the claw-shaped bolt 85 (as shown at bolt 83). collections.

In the same way as the locking mechanism 110, another locking mechanism 111 as well as the locking mechanisms 112 and 113 belonging to the first longitudinal side wall 61 are also provided.

After all blocking mechanisms 110, 111 have been locked. 112. 113 in all four corners of the formwork, a mold 63 is formed which can be filled with liquid gas-concrete pulp.

By means of a suitable lubricant it is possible to seal still existing gaps and cuts between the side walls 22, 89 arranged perpendicular to each other. By filling the reinforced concrete debris up to the filling state, the matured reinforced concrete debris can increase its volume up to the upper edges of the side walls 61, 62, 88, 89 and form a reinforced concrete cake. The excess portion of the gas-concrete cake is cut off after a predetermined ripening period. At the next station, to which the gas-concrete cake mold 63 is conveyed, the solid concrete cake is detached and all the locking mechanisms 110, 111, 112, 113 are unlocked.

The two locking mechanisms 112, 113 belonging to the first longitudinal side wall 61 are shown in FIG. 3 are obscured, but are indicated by the arrow symbols in FIG. First

An unlocking device 2 according to the invention, which is designed as a locking device 1 according to the invention, is provided at a mold unblocking station 63. Preferably, the unlocking devices 2 and the locking device 1 are connected to one another in a device according to the invention by a larger structure, which is preferably arranged between workstations.

For the sake of clarity, the same reference numerals are used for the same parts. The more essential components required for unlocking are also shown in side and front view, since the operating means of the unlocking device 2 as well as the operating means of the locking symmetrically with respect to the bottom 14 of the columns of the respective structure.

The devices 1 are arranged 63 on similar crossbars

In FIG. 4 shows a side view of two of the four necessary working means 114, 115 which are mounted on the crossbars 116, 117 of the structure 4 having a square profile. The crossbars 116, 117 are located in respect of the position of the front side walls 88 and 89 outside the mold 63.

The working means 114 and 115 are each provided with a sliding member 118, 119 with a guide rail 120, 121 and with a sliding element 122, 123 which are always inclined at an angle of preferably about 45 degrees to the vertical towards the front side walls 88. 89. The corresponding sliding element 122. 123 is then guided by the corresponding sliding member 118, 119 in the direction of the locking device 110, 111 in the region of the formwork corners. The two unlocking actuators 124, 125 and the unlocking lever arms 126, 127 are rotatably mounted on both sliding elements 122, 123, and the unlocking actuator 124, 125 is rotatably mounted in the center of the unlocking lever arm 126, 127. an opening lever arm 128, 129, each rotatably mounted at one end thereof, to which center an opening actuating element 130, 131, which is also rotatably mounted on the sliding element 122. 123, is rotatably connected.

The opening of the locking mechanisms 110 and 111 is such that, as shown on the locking mechanism 111, the working means 114 and 115 approach the outside of the shuttering corners to the extent that the unlocking lever arms 126, 127 engage the respective leading bevels 108 of the bolts 83. 85. 4, for example, the unlocking lever arm 127 engages under the bevel 108 at the end of the claw shape of the bolt 85 by actuating the unlocking actuator 125. The unlocking actuator 125 lifts the unlocking lever arm 127 by pulling. .

Due to the existing high adhesion of the gas-concrete cake to all side walls 61, 62, 138, 89, it is preferable that all these side-walls 61, 62, 88, 89 are folded away from the gas-concrete cake by machine. In this case, the opening lever arm 129 is pulled by the opening control element 131 from the interior of the mold 63 against the second front side wall 89, which is tilted while being supported by a pivoting device 132, for example stationary.

The same procedure is carried out on the first front side wall 88, for example with a pivot device 133 which is equally stationary. The pivot devices 132, 133 have the same design as the pivot devices 90, 91 according to FIG. Third

Since there is at least the same adhesion between the longitudinal side walls 61, 62 of the mold 63 and the aerated concrete cake as for the front side walls 88, 89, it is possible to provide an additional component on the corresponding working means 114, 115, in particular on the sliding element 122, 123. each comprising an opening lever arm for opening the longitudinal side walls 61, 62, which are pivoted by corresponding opening controls so that the longitudinal side walls 61, 62 are pushed away from the interior of the mold 63 and folded out.

In FIG. 5 shows the working means 134, 135, which have substantially the same design as the other working means of the unlocking device 2, with the aid of these working means 134, 135, which can also be arranged on a hinged structure and can be adjusted accordingly, it is also possible to overcome the adhesion of the longitudinal side walls 61, 62 to the gas-concrete cake.

The working means 134, 135 is rigidly connected at one end to the cross member 136, which can be folded up to the level of the upper edges 80, 81 of the longitudinal side walls 61, 62 so that the upper edges 80, 81 form the lower folding limits of the cross member 136.

The operating means 134, 135 comprise at least one rigidly attachable adjusting arm 137, 138 arranged perpendicular to the longitudinal side walls 61, 62 on which the opening lever arm 139, 140 is rotatably mounted, to which center the opening operating element 1A1, 142 is rotatably connected. which rotates and adjusts the opening lever arm 139, 140.

Upon completion of the separation of the front side walls 88, 89, the two longitudinal side walls 6i, 62 are detached.

By actuating the opening controls 141, 142 one end of the opening lever arms 139, 140 is moved to push the corresponding longitudinal side wall 61, 62 away from the gas-concrete cake.

Likewise, the longitudinal side walls 61, 62, like the front side wall 88, are folded out while being supported by the pivoting devices 143, 144.

The gas-concrete cake is then ready for further processing.
