Definitions
- the invention relates to a support with a removable support head, which has on its underside an extension engaging in a hollow profile of the upper end of the support.
- Support heads of this type are used, with or without a drop sleeve, to support ceiling formwork elements.
- the extension of the support head has a recess which is aligned with a recess in the support when the support head is inserted, so that a bolt extending transversely to the longitudinal axis of the support can be inserted through these two recesses and firmly connects the support head to the upper end of the support .
- axially extending plate of the prop head are attached. The prop head is then attached with the help of screw nuts screwed onto the lower end of the threaded bolts.
- System formwork for concrete includes several column heads that are adapted to the respective application, but also, for example, column heads that are suitable for inclined columns with which vertical formwork walls are supported.
- the object of the invention is to develop a connection between the support and the support head which is quick to assemble and simple to manufacture.
- a spring-loaded pawl is pivotally mounted on the extension of the support head, which latches behind a stop on the support when the support head is placed on the support.
- An advantage of the invention is that when the support head is placed on the upper end of the support, the spring-loaded pawl engages behind the stop and the support head is thus attached to the support. Since, in embodiments of the invention, a base plate of the support head has centering pins which engage in centering holes of the head plate of the support when the support head is in place, the connection of the support head to the support according to the invention can already be sufficient to reduce the forces occurring from the support initiate elements in the support. Where this appears questionable, in addition to the attachment according to the invention, the support head can also be attached in a known manner on the upper end of the support. In any case, the attachment of the support head according to the invention is helpful if the support with attached support head without additional
- the stop which is engaged by the pawl when the support head is in place, can be designed as desired, for example, it can be formed from a bolt which extends through the cavity of the hollow profile in the tube wall of the support and extends transversely to the support axis.
- the part of the pawl engaging behind the stop is designed such that, in cooperation with the stop, it securely holds the support head placed on the end of the support.
- the invention can be implemented with particular advantage in a support which has at its upper end a head plate which has a recess in the region of the interior of the hollow profile through which the extension arranged on the underside of the support head passes.
- the lower edge of this recess serves as a stop for the pawl which, when the support head is inserted, is first pressed back against the spring force when passing through the recess and as soon as the region of the extension containing the pawl has passed through the recess, swings out the lower edge of the recess behind.
- a base plate of the support head has a cutout through which the pawl is accessible for the purpose of unlocking with the aid of a suitable rod-shaped tool or the like.
- This embodiment of the invention can be further developed in that the pawl has an extension which extends up to the recess in the head plate of the support or is so long that it also extends into the recess of the base plate of the support head or still extends further upwards so that the pawl can be pivoted back in a simple manner.
- the pawl has a recess which is accessible from above through the cutouts and is suitably arranged for inserting a rod-shaped tool when the pawl is unlocked.
- an opening is provided in the wall of the support through which the pawl is accessible for the purpose of unlocking, so that, for example, a rod-shaped tool can directly attack the part of the pawl that engages behind the stop. A force can then immediately be exerted on the latch which is tangential to the swiveling movement required for unlocking.
- an opening can also be provided in the support wall, through which a pin can be inserted, which blocks pivoting of the pawl from its locking position.
- the rod-shaped tool which is also used to unlock the pawl, can preferably be used for this purpose.
- the invention can advantageously be used wherever the support has at its upper end a recess arranged in the support axis, that is to say not only in the known supports which consist of one tube, but also in those supports which have another Have cross-sectional shape, for example consist of a solid profile and have a central bore at its upper end.
- the spring force that leads the latch into the locking position can be generated in various ways.
- a body made of an elastic plastic which is arranged in the pivoting area of the pawl, for example after the insertion of the support head, it is subsequently inserted into the recesses in the base plate and / or head plate. This has the advantage that it allows free passage through covers these recesses so that no concrete or other contamination can pass through these recesses.
- the plastic body has a cell structure, such as a foam rubber.
- the spring force can also be generated by coil springs or, in a preferred embodiment, by a leg spring.
- the invention can be used particularly advantageously in supports in which a base plate of the support head has centering pins which engage in centering holes in the head plate of the support when the support head is attached.
- Fig. 1 shows a side view of the base plate of a column head with extension.
- Fig. 2 shows a section along the line II-II of Figure 1.
- FIG. 3 shows a longitudinal section through an upper end of the support with the support head attached, with another embodiment of a locking pawl.
- Fig. 4 shows a section through the lower part of a column head;
- Fig. 5 shows a section along the line V-V of Figure 4.
- FIG. 6 shows a further embodiment of the invention in a representation corresponding to FIG. 3.
- a head plate 8 is welded onto the upper support end, which has a recess 9 which is provided in the region of the recess 3, essentially in the region of the longitudinal axis of the support, when the support head is attached.
- the support consists of a support tube 10, in the cavity of which the extension 2 engages.
- the base plate 1 has on its underside centering pins 11 which fit into the centering pins provided in the head plate 8. engage holes 12.
- the base plate can also have screw bolts on its underside which reach through holes in the head plate 8. At the lower end of such bolts, not shown, screw nuts can be screwed on, with which the support head is connected to the support in addition to the connection made by the locking pawl 6.
- a body 13 made of foam rubber is inserted into the recess 3 of the base plate 1, which body tends to pivot the pawl 6 into the position shown in Figure 2.
- This body 13 is so large that it also passes through the recess 9 in the base plate 8.
- the body 13 closes the recess 3 almost completely and also a large part of the recess 9.
- the body 13 can be fastened in the recess 3, for example glued in, but it can also be inserted subsequently into this recess if the column head is placed on the column.
- a pawl 6 shown in Figure 2 this has in its upper region a plurality of steps 14, with which it engages behind the lower edge 15 of the recess 9 when it has passed through the recess 9 when the support head is placed so far that it passes through the spring force can be pivoted.
- the pawl 6 has an upwardly extending extension 18 which extends up into the recess 3 and is gripped in the recess 3 with the aid of a rod-shaped tool 25 and can be pivoted against the spring action, so that the steps 14 below the edge the recess 9 of the head plate 8 are pivoted away and therefore give the extension for pulling out the support head.
- the pawl 16 has a recess 17, which also serves that a rod-shaped tool introduced from above, the pawl 16 can be pivoted back against the spring force acting on it, so that it from the lower edge of the head plate 8 is released.
- the spring force is generated by two helical springs 19 and 20 which endeavor to pivot the pawl around the bolt 7 such that the upper edge 21 or 14 of the pawl engages behind the lower edge 15 of the head plate 8.
- the pawl also has an extension 22 which projects downward beyond the pivot pin and on which the spring 20 engages.
- the extension 22 also has a surface 23 running transversely to the longitudinal axis of the support.
- a rod-shaped tool 25 can be inserted transversely to the longitudinal direction of the support and inserted under the surface 23, so that the pawl 16 is placed in the engaged position and is additionally locked.
- the rod-shaped tool 25 can also be used to engage the upward-facing extension 18 and to pivot the pawl 16 against the direction of the spring force for unlocking.
- the embodiment according to FIGS. 4 and 5 differs from the embodiments according to FIGS. 1 to 3 in that the spring force leading the pawl 6 into its locking position is generated by a leg spring 26.
- the embodiment according to FIG. 6 differs from the embodiments described above in that the pawl 27 has no upwardly extending extension 18 and instead the rod-shaped tool 25 is pushed through the recesses 3 and 9 and pressed onto a surface 28 must be so that a force is exerted on the pawl 27 which is directed downwards at a distance from the pivot pin 7.
- This embodiment has a spring 30 which is supported on a support 29 on the legs 4 and 5 and which engages on the underside of the pawl 27, and additionally a helical spring 31 which is supported on a support 32 in the legs 4 and 5 .
- the prop head can be mounted on any standard ceiling prop that has a protrusion that protrudes on the inside.
- the connection according to the invention can be used not only for fixing support heads on supports, but also for fixing other suitable parts, e.g. Knot parts for scaffolding or frames.
