DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns a support with a removable support head which exhibits, on its under side, an extension engaging a hollow profile of the upper end of the support.
These types of support heads serve, with or without drop bushings, to support ceiling mould elements. In known supports, the extension of the support head exhibits an opening which, with seated support head, aligns with an opening in the support so that, by means of these two openings, a bolt can be introduced from the outside in a direction transverse to the longitudinal axis of the support, the bolt securely attaching the support head to the upper end of the support. It is also known to rigidly attach a head plate, running transversely to the support axis, to the upper end, the head plate having bore holes through which threaded bolts penetrate, the bolts being secured to a support head plate which likewise runs transversely the support axis. The support head is then secured with the assistance of nuts screwed onto the lower end of the threaded bolt. Mould systems for concrete include a plurality of support heads which are adapted to each application and, for example, support heads that are suitable for diagonal supports with which vertical moulding walls can be supported.
The underlying purpose of the invention is to develop a connection between a support and a support head which can be mounted quickly and which is easy to manufacture.
SUMMARY OF THE INVENTION
This purpose is achieved in accordance with the invention in that, on the extension of the support head, a spring-loaded ratchet is pivotably attached, the ratchet lockingly engaging a support stop of the support head mounted on the support.
The advantage of the invention is that, when mounting the support head on the upper support end, the spring-loaded ratchet latches behind the stop to thereby secure the support head on the support. Since, in embodiments of the invention, a support head base plate exhibits centering pins engaging centering holes in the head plate of the support when the support head is mounted, it is possible for the connection between the support head and the support according to the invention to already be sufficient to guide the forces which occur from the mould elements onto the supports. Where this appears questionable, auxiliary upper support end supports can be attached, in a matter which is known, in addition to the attachment of the support head in accordance with the invention. In any event, the attachment of the support head in accordance with the invention is useful for transporting the supports, with mounted support heads, without additional attachments.
The stop which, with mounted support head, is engaged by the ratchet, can be arbitrarily configured. It can, for example, be configured as a support pipe wall bolt which runs transverse to the support axis and penetrates through the hollow region of the hollow section. The portion of the ratchet which engages the stop is so configured that it, together with the stop, securely holds the support head in its mounted position on the support end.
The invention can be realized, with particular advantage, in a support which exhibits a head plate at its upper end, the plate exhibiting, in the vicinity of the inner region of the hollow profile, an opening through which the extension arranged on the under side of the support head penetrates. In an embodiment of the invention, the lower border of this opening serves as a stop for the ratchet which, when mounting the support head, initially, during penetration through the opening, is pushed back against the force of the spring and as soon as the region of the extension which contains the ratchet penetrates through the recess, the ratchet swings out again to engage the lower edge of the recess.
The release of the ratchet can, on the other hand, transpire in various ways. In one embodiment of the invention a base plate of the support head exhibits an opening through which the ratchet can be accessed and released with the assistanc
