Scaffolding shore

Abstract

 The invention relates to a scaffolding shore for a scaffolding construction comprising at least two vertical elements, wherein the scaffolding shores each comprise two telescopic tubes which can be fixed in position relative to each other by means of a mortise and tenon joint.

Description

[0001] The invention relates to a scaffolding shore.

[0002] Scaffolding shores are generally known. They are made up of obliquely extending elements within a scaffolding construction, which function to prevent the scaffolding from tilting. They are also used for supporting ridge trestles of a scaffolding construction. A ridge trestle is used, for example, when work is to be carried out on a high-pitched gable and the weather conditions render it necessary to provide protection against the environment while the work is being carried out. In that case a scaffolding construction is provided with a ridge trestle and a tarpaulin or a plastic sheet is draped over the ridge trestle. A ridge trestle is made up of a girder extending transversely to the gable, which is connected to the rest of the scaffolding by means of scaffolding shores to which the present invention relates.

[0003] It is pointed out that from DE-A-19631233 an obliquely extending element is known for supporting a scaffolding bridge construction. One side of this scaffolding bridge construction is supported against the gable on which work is to be carried out, whilst the other side is supported on the obliquely extending elements. In order to enable proper adjustment of the height, use is made of oblique elements which can be adjusted by means of mortise and tenon joints.

[0004] The scaffolding shores must be adjustable so as to make it possible to shore the scaffolding structure in dependence on the type of scaffolding being used, whilst in the case of ridge trestles the scaffolding shores need to be adjustable in order to enable precise adjustment of the height of the ridge trestle for the purpose of adapting the workplace under the tarpaulin as well as possible to the available space.

[0005] The present invention provides a scaffolding shore which is provided with two telescopic tubes which can be fixed in position relative to each other by means of a mortise and tenon joint. According to a first preferred embodiment, the spacing between the holes in one of the tubes is different from that between the holes in the other tubes. In this manner a kind of nonius effect is obtained, which enables a precise adjustment.

[0006] According to another embodiment, the holes in at least one of the tubes are spaced apart by at least two mutually different distances. In this manner the degree of adjustability is enhanced even more.

[0007] Other attractive preferred embodiments will become apparent from the other claims.

[0008] The present invention will now be explained in more detail with reference to the appended drawing, which shows a scaffolding construction comprising a number of scaffolding shores according to the present invention.

[0009] The figure shows a scaffolding construction, as a whole indicated by reference numeral 1, which is made up of two vertical ladder elements 2 and 3, respectively, in which a working platform 4 is placed. Two scaffolding shores 5, 6 are provided for shoring the scaffolding construction 1. According to the invention, said scaffolding shores are each made up of two telescopic tubes, which can be fixed in position relative to each other by means a mortise and tenon joint. This makes it possible to select the suitable dimension for the scaffolding shore in dependence on the width of the scaffold being used.

[0010] Furthermore a ridge trestle 7, which is in essence made up of a girder 8, is provided on the scaffolding construction, which girder is connected to two scaffolding shores 9, 10 and 11, 12, respectively, at each of its ends. Said scaffolding shores 9-12 are connected to the scaffolding construction 1 at their lower ends. The adjustability of the length of the scaffolding shores 9-12 renders it possible not only to adjust the height of the girder 8 but also, for example in the case of oblique roof constructions, to actually use a ridge trestle. Furthermore it is possible, as can be seen in the figure, to extend the ridge trestle with scaffolding shores a 13, 14 to a next scaffolding construction, which is attractive when carrying out work on a so-called broken roof construction.

[0011] The drawing finally shows a loose scaffolding shore 15, which is connected to the girder 8 and which can be used for anchoring the ridge trestle, for example by connecting it to the gable structure.

Claims

1. A scaffolding shore for a scaffolding construction comprising at least two vertical elements, characterised in that the scaffolding shores each comprise two telescopic tubes which can be fixed in position relative to each other by means of a mortise and tenon joint.

2. A scaffolding shore according to claim 1, characterised in that the spacing between the holes in one of the tubes is different from that between the holes in the other tubes.

3. A scaffolding shore according to claim 2, characterised in that the holes in at least one of the tubes are spaced apart by at least two mutually different distances.

4. A scaffolding shore according to any one of the preceding claims, characterised in that the scaffolding shore is suitable for constructing a ridge trestle on a scaffold.

5. A ridge trestle for a scaffolding construction, comprising a substantially horizontally extending girder and scaffolding shores according to any one of the preceding claims, which extend obliquely downwards from said girder.

6. A ridge trestle according to claim 5, characterised in that the scaffolding shores are each pivotally connected in a vertical plane to the girder and to a scaffolding construction.

7. A ridge trestle according to any one of the preceding claims, characterised in that a tarpaulin is draped over said ridge trestle.
