Assembly scaffolding

Technical field

The invention relates to a mounting scaffolding, in particular for the assembly and disassembly of gypsum plasterboard or other ceiling soffits and cladding ceiling slabs.

BACKGROUND OF THE INVENTION

At present, many different types of scaffolding constructions made up of separate scaffolding elements are commonly used in the construction industry. In addition to simple tubular scaffolds made up of a system of interconnected individual scaffold tubes, which are usually used in larger constructions, such scaffold constructions consisting of preformed scaffold modules are also known which substantially speed up their assembly. Typically, these modular scaffolding structures are designed to be mobile, allowing their local mobility as needed on site.

An example of such a mobile scaffolding is a solution known from Czech Patent Specification No. 286177 or from Czech Patent Specification No. 286428. The mobile scaffolding according to these documents consists of a system of vertical frames, each consisting of two parallel vertical columns, which are mutually connected by horizontal rungs. The frames are connected to each other by a horizontal working platform that rests on a rung or anchoring brackets, with longitudinal braces for bracing in the diagonal direction and the individual vertical frames fitted with castors. The advantage of the solution according to these documents is, in comparison with other similar types of mobile scaffolding scaffolds, the fact that the surface of the mobile scaffolding

The scaffold tower can extend in two mutually perpendicular horizontal directions, and that there is no need to create a separate extension system oriented transversely to the existing extension system or the extension system. that the width of the scaffolding can be easily changed as well as the distance of the scaffolding to the building being constructed can be easily changed by simple auxiliary means.

In addition to these mobile scaffold towers, height-adjustable scaffold towers are known, either as in the aforementioned Czech document No. 286428, by their height adjustment, or on the principle of telescopically extending couplings with appropriate arrestment, as is the case Utility Model No. 747, in which the ejection is carried out by means of a lifting shaft provided with toothed pinion and rotary crank. A similar extensible scaffolding support according to Czech utility model No. 206 is also known. A scaffolding consisting of at least two scaffolding stands with hydraulic height adjustment or a mounting platform according to the Czech patent specification is also known from Czech patent specification 289665. No. 282164, slidingly mounted on four vertical supports, in which its height adjustment is carried out by means of a rope and pulley system with a winding system.

Due to their relatively small size and quick assembly, these mobile and height-adjustable scaffold towers can be used well for building work inside buildings or for finishing or interior repair work. Their disadvantage, however, is that they only ensure the position and movement of workers at the required height, but the actual work itself does not facilitate these scaffolding in any way. This disadvantage is particularly noticeable in the assembly or dismantling of gypsum or other cladding panels, especially of larger dimensions, where at least two additional auxiliaries are required to handle and position these panels only.

SUMMARY OF THE INVENTION

The aforementioned disadvantages of the prior art in this field are largely eliminated by mounting scaffolding, in particular for the assembly and dismantling of gypsum plasterboard or other ceilings and cladding, formed by an interconnected system of vertically oriented supporting scaffold frames which consist of a pair of parallel supporting supports The support according to the invention is characterized in that at least one pair of supporting scaffold frames is provided with a system of upwardly extendable mounting supports for handling and positioning the mounted plasterboard or other cladding board.

Typically, a system of two vertically oriented scaffolding frames with one working platform is fully sufficient, with the advantage that the mounting supports are arranged in two independently extendable pairs.

Also preferably, each independently extensible pair of mounting supports is disposed on a single scaffolding frame which is provided with a drive for their synchronous extension. This guarantees both stability of the assembled ceiling slab when handling it, as it rests on a total of four mounting supports and, secondly, the possibility of positioning the assembled ceiling slab on inclines, for example in attic rooms. This is made possible by each pair of mounting brackets supporting the mounted ceiling plate, which extends to a different height, thereby positioning the ceiling plate in the mounting position at an appropriate inclination.

In a further preferred embodiment of the invention, the drive for extending the mounting supports on each supporting scaffold frame is formed by an electric motor with a winding pulley of the mounting support extension cables. Also advantageously, the mounting steps are: φ φ φ φ φ φ φ φ φ · · · · · · φ φ φ φ φ φ φ φ φ φ φ φ φ

4 supports are displaceably provided in the support legs of the supporting scaffold frame, the withdrawable ropes being guided from the winding pulley through the transfer rollers through the inner space of the support legs, where they are anchored to the inner ends of the mounting supports.

Of course, other drive systems can be used, such as pneumatic, hydraulic, or other mechanical ejection of the mounting brackets from the support posts, but the above-mentioned cable system with an electric motor-driven winding roller seems to be both simpler and most advantageous, especially in terms of light weight individual scaffolding frames, low purchase costs, essentially negligible maintenance requirements, and allowing a simple, for example remote control, to eject the mounting supports from the working platform. This is not an application of the known systems of height-adjustable scaffolding, because the extension of the individual elements of these known scaffolding is only solved with regard to their sufficient load-bearing capacity and stability and cannot be assembled for assembly purposes in many respects. to be used in the present invention.

The invention furthermore provides that the outer ends of the mounting supports are provided with protective caps to prevent damage to the mounted plasterboard ceiling and to its slippage when mounted in an inclined position.

For easy retraction of the mounting brackets into the initial position, the mounting brackets are preferably provided with an additional weight and the support scaffold frames are provided with castors to allow the entire scaffold tower to travel.

· »··· ♦ ·· ····

The main benefit of the assembly scaffolding, which is provided according to the invention with mounting brackets which set the assembled, for example, plasterboard ceiling slabs into the required position, is thus a substantial simplification of work with a multiple increase in its productivity and labor saving. The same advantages, which other known scaffolding does not allow, are of course also achieved during dismantling or dismantling. when replacing these ceiling slabs.
