Embodiment Construction

[0013] figure 1 The principle of a fastening plate engaged with a concrete structure 1 is shown. The fastening plate comprises a plate part 2 and an anchor part 3 . Structural fasteners 10 are fastened on the plate portion 2 . The anchoring part 3 can be fastened to the plate part 2 by welding or screwing, for example. The fastening plate is placed in the concrete before the concrete dries, whereby the fastening plate is fastened in the concrete while the concrete is hardening.

[0014] exist figure 1 The concrete structure 1 and the structural fastener 10 are shown in dotted lines. The concrete structure 1 may be any known structure. Thus, the structural fastener may be of any construction known per se. For example, different structural elements of a building can be fastened to the structural fasteners 10, thereby transferring the forces and loads caused by these structural elements to the concrete via the fastening plate. These facts are known to those skilled in the ...

Abstract

The invention relates to a fastening plate comprising a plate-like part (2) and anchorage parts (3) fastened thereto, the fastening plate being intended to be arranged in concrete before the concrete hardens and further to be fastened to the concrete by means of the concrete hardening. Each anchorage part (3) is fastened to the plate part (2) by means of a threaded connection provided by a threaded part (4) at the anchorage part and a hole (6) with internal threads (5) and provided in the plate part.; The anchorage part (3) comprises an expansion part (6) extending from the threaded part (4), and around the hole (6) in the plate part (2) there is a groove (8) forming a concentric circumference with the hole, the inner surface of the groove being arranged to consist of a flange part (9) around the hole, the flange part being arranged to yield and cover the groove (8) under the influence of the expansion part (7) when the threaded part (4) of the anchorage part is tightened to the internal threads (5) of the hole (6) in the plate part.

Description

technical field [0001] The present invention relates to a fastening plate comprising a plate-shaped portion and an anchor portion fastened to the plate-shaped portion, the fastening plate being set in concrete before the concrete hardens and then fastened in the concrete by the hardening of the concrete , wherein each anchor portion is fastened to the plate portion by means of a threaded connection provided by a threaded portion on the anchor portion and an internally threaded hole provided in the plate portion. Background technique [0002] Various fastening plates are well known in the construction industry today. Fastening plates are elements that are to be fastened in concrete before the concrete hardens. The fastening plate is made of a suitable material such as steel. According to the prior art, the anchor is fastened to the plate in a suitable manner, for example by welding the anchor to the face of the plate or into a hole extending through the plate. Threaded con...
