CS252409B1 - Form for the production of concrete foundation with embedded anchoring element - Google Patents

Abstract

The mold is intended primarily for building a larger amount of foundation with an embedded anchor element for installing steel structures. It is equipped with supporting arms attached to the side of the mold shell, radially to its axis. At the ends of the supporting arms there are holes with internal thread for adjusting screws, which are equipped with swing supports. At the same time, pins are attached to the upper edge of the mold shell, on which the anchor element holder is attached. The holder forms a crossbar across the edges of the shell e, is equipped with holes for attaching to the dowels and holes for attaching the anchor element with anchor bolts and nuts. The assembled form is placed above the excavated trench or roughly prepared terrain and is leveled to the required height using adjusting screws. After the concreting is completed and the concrete has set, the nuts are unscrewed from the anchor bolts, the anchor element is removed from the pins, and the form shell is removed from the foundation. The anchor element remains a permanent part of the foundation.

Description

BACKGROUND OF THE INVENTION The present invention relates to a mold for the production of a concrete foundation with an embedded anchoring element, in particular for the installation of steel structures.

Until now, the production of concrete foundations with an embedded anchoring element used stable wooden or steel formwork, or so-called permanent formwork. As a rule, the anchoring element was fitted into the anchoring holes formed in the head of the foundation or in a very laborious manner, for example with wooden supports, wedges and the like, fixed to the formwork so that the foundation can be concreted in one production operation. The disadvantages of these types of formwork are, in particular, their difficult height and directional alignment and the necessity of sub-base concrete. Similarly, the precise fitting of the anchoring elements in the foundation head has caused considerable difficulties in the construction industry.

The above-mentioned drawbacks of the types of formwork used so far substantially reduce the mold for manufacturing foundations with an embedded fastener according to the invention, which is based on the fact that the mandrel above the upper edge on which the fastener grip is mounted is attached to the mold shell. At the same time, support arms are attached to the mold shell radially to its axis, at the ends of which there are internally threaded holes for the set screws. The anchorage grip forms a crossbar over the upper edges of the housing, which is provided with holes for mounting on the mandrels and holes for gripping the anchorage element. The anchoring element is attached to the anchor with anchor bolts and nuts. The setscrews in the support arms are equipped with swinging supports so that the mold does not change the set height and directional position even in muddy terrain during concreting of the foundation.

The mold according to the invention is particularly suitable for use in concreting a plurality of foundations with an anchoring element inserted for its easy height and directional alignment by means of adjusting screws. A mold with a fixed anchoring element allows the foundation to be concreted in one production operation without the need for sub-base concreting.

In the accompanying drawings two exemplary embodiments of a mold with an anchoring element are shown, in which Fig. 1 shows a mold for concreting the foundation directly into the excavated excavation and Fig. 2 shows a mold for concreting the foundation on roughly ground. ^E

The mold for manufacturing a concrete foundation with an anchoring element inserted 10 has mandrels 2 attached to its shell 4 exceeding its 252409

The upper edge on which the anchoring element grip 7 is mounted. The anchoring element grip 7 forms a crossbar over the edges of the sheath 1 and is provided with holes 8 for mounting on the mandrels 2. At the same time, holes 9 are provided in the grip body 7 By means of anchor bolts 11 and nuts 12. Supporting arms 3 are attached radially to its axis 1 to the mold shell 1, the ends of which are provided with tapped holes 4 into which the set screws 5 are screwed. The set screws 5 are provided at their ends Swivel armrests 6.

On the mandrels 2 projecting over the upper edge of the mold shell 11, a grip 7 with anchoring element 10 is slid. The mold is set over a excavated excavation or rough ground and is adjusted to the desired height by means of adjusting screws 5. Then the foundation is concreted. After the concrete has set, the nuts 12 are unscrewed from the anchor bolts 11, the anchor element 10 is removed from the mandrels 2 and the mold shell 1 is removed from the base. The anchoring element 10 then remains a permanent part of the foundation.
