Problems solved by technology

Disadvantageously, shafts and hinges fixedly mounted to the longitudinal support are required to enable adjustment of the longitudinal support
This embodiment is structurally expensive and entails high manufacturing costs
Furthermore, it is disadvantageous that a loss of function may occur in the hinge or in the longitudinal guide due to dirt deposits
[0004] Other carrier devices for roof formwork are known from FR2842848A1 and FR2900176A1, but they do not present an effective solution to the above-discussed disadvantages of the prior art

Embodiment Construction

[0031] figure 1 A carrier device 1 is shown for supporting a common roof formwork (not shown); the formwork elements may be formed from one or more formwork panels (not shown). The carrying device 1 has a plurality of multiple supports 2 which are each composed of two longitudinal supports 3 arranged at a distance from one another. These multiple supports 2 are arranged in the same horizontal plane. In the embodiment shown, the multiple supports 2 are arranged in two rows, wherein the ends of the longitudinal supports 3 facing each other are arranged overlapping. Furthermore, the carrying device 1 has a main support 4 on which the multiple support 2 is placed. The main support 4 is supported on support elements (not shown).

[0032] as by Figure 2 to Figure 4 As can be seen, the longitudinal supports 3 are connected to each other by connecting elements 5 , wherein, in the embodiment shown, each multiple support 2 has exactly two connecting elements 5 . As will be explain...

Abstract

The invention relates to a support device (1) for concrete formwork, in particular ceiling formwork, comprising at least one multiple-rail assembly (2) having at least two longitudinal rails (3), wherein the longitudinal rails (3) are joined to one another by means of at least one joining element (5). The device is characterised in that at least one of the longitudinal rails (3) comprises a through-opening (6) permitting the joining element (5) to pass through, wherein the joining element (5) is moveably arranged in the through-opening (6) and substantially perpendicular to the longitudinal direction of the longitudinal rail (3), such that the distance between the longitudinal rails (3) or the angular position of the longitudinal rails (3) in relation to one another can be changed.

Description

technical field [0001] The invention relates to a support device for concrete formwork, in particular roof formwork, which has at least one multi-frame with two longitudinal supports, wherein the longitudinal supports are connected to each other by at least one connecting element. Background technique [0002] A support device of this type for formwork structures consisting of concrete slabs is known from FR 2955877 A1. The carrying device has a combined unit of two longitudinal supports connected to each other by adjustable connecting rods. In a first embodiment, the connecting rod consists of two parts articulated to one another, which are each supported pivotably via a hinge on an associated longitudinal support. By pivoting the parts relative to one another, the distance between the longitudinal supports can be varied. Furthermore, a second embodiment is described, in which the connecting rod is mounted in an articulated manner on one longitudinal support and is mounte...
