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 12 are fastened to 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 fasteners 12 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 12, thereby transferring the forces and loads caused by these structural elements to the concrete via the fastening plates. These facts are known to those skilled in th...

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 a collar part (7)extending from the threaded part (4)and comprising a first flange part (8) and a second flange part (9)at a distance therefrom in the longitudinal direction of the anchorage part, whereby a groove (10) is formed between the first and the second flange part. When the threaded part (4) of the anchorage part is screwed in the internal threads (5) of the hole (6), the first flange part (8) is arranged to be pressed against the surface of the plate part (2) around the hole. When the first flange part (8) is pressed against the surface of the plate part (2), it is arranged to yield and cover the groove (10) between the first and the second flange part.

Description

technical field [0001] The present invention relates to a fastening plate comprising a plate portion and an anchor portion fastened to said plate portion, said fastening plate being arranged in concrete before hardening of the concrete and then fastened in concrete by hardening of the concrete, wherein Each anchor is fastened to the plate by means of a threaded connection provided by a threaded portion on the anchor and an internally threaded hole provided in the plate. 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 connections have also been used to secure the ...
