CS209172B1 - Fixture for fixation of suspension platforms - Google Patents

Abstract

A device for fixing the position of suspended platforms used in work on the facade of panel buildings, the essence of which lies in the use of opening pliers, which are spread apart in the joint of the panel building, fixed in the open position and limiting the movement of the platform. The tensioning of these pliers, fixed with a chain and a pin, gives a selectable force, preventing them from being torn out of the joint.

Description

(54) Suspension platform fixture

Annotation

The fixture for fixing the position of the suspension platforms used in the work on the facade of panel buildings, which is based on the use of tongs that strut in the joint of the panel object, fasten in the open position and limit the movement of the platform. The tension of these pliers, fixed by chain and mandrel, gives a selectable force to prevent them from being pulled out of the joint.

BACKGROUND OF THE INVENTION The present invention relates to a fixture for fixing the position of suspension platforms used in work on panel buildings.

Suspended work platforms are used to perform various work mostly on the exterior walls of buildings. During work where it is necessary to apply a certain force perpendicularly to the wall of the building (eg sealing joints, drilling holes, pruning grooves, etc.), the suspended platform is pulled away from the wall due to the applied force. This greatly deteriorates the working conditions and causes the platform to swing. Sometimes this makes it impossible. So far, another rope, lowered from the roof cantilevers and fastened to the ground under the footbridge, has been used to limit the footbridge movements. The movements of the platforms are somewhat reduced in this way, but at a higher building height, the rope sags and the anchoring is ineffective.

These drawbacks are eliminated by the device according to the invention, which consists of two steel angles movably connected to each other by hinges so that the angles together form a T-shaped cross-section, rotatable in X-shaped hinges. large shoulders leaning on two adjacent panels. The remaining arms of the angles form the support arms, determining the depth of insertion of the spacer arms into the joint and carrying a pair of firmly fixed levers, which together form the letter V. At the free ends, these levers are provided with one spindle and the other is provided with a steel eye behind which the fixture for fixing the position of the platforms is attached to the suspension footbridge. Said jig is used in such a way that the angles are inserted into the joint between the panels and by pressing the arms together they engage the edges of the panels. Pulling the chain on the dark ensures that the fixture is fixed. The fixture is attached to the suspension platform by means of a ring at the upper end

_v OBJECT Fixture for fixing the position of suspension platforms when working on the facade of panel buildings, characterized in that it consists of two steel angles (1) movably connected to each other by hinges so that the angles together in cross section form the letter T, rotatable in hinges to X shape, The mutually adjacent arms of the angles form spaced arms which can be inserted into the joint between two adjacent one arms so that the angles can be clamped into the horizontal and vertical joints by means of a steel carabiner, leather strap and the like. The assumed force of gripping on the facade at one place is about 30 kp, which brings about a load of 0.1 MPa in the area of contact with the edges of the panels of about 30 cm ² . This force exceeds the strength of the worker who rests on the wall roughly 2 times with the working tool (max. Assumption max. 20–30 kp) and is sufficient to stabilize the footbridge during normal work. Failure to release the tool and move it: the platform will produce a moment of force which! it easily disproves the anchor and cannot compromise the platform's balance. The designed fixture is simple, easy to make from available materials with common tools. The platform anchoring and uncoupling is very quick and easy. Anchoring can be done in horizontal and vertical joints between panels and the fixture adapts to all common joint widths. The force required to clamp the fixture can be easily adjusted to the required range, exceeding this force can be limited by the thickness and elasticity of the material used on the! jig arms (structural steel is most suitable). An embodiment of the device according to the invention is shown in the attached figure, wherein the pins 1 are movably connected to each other by a T-shaped hinge. The steel levers 2 are attached at an angle of 45-80 ° so as to form a letter V. a second chain 3 which stabilizes their relative position in the working position. One of the levers 2 is provided at its free end with an eye 4 for attaching the fixture to the suspension platform. The tool can be used in the construction industry when working with a movable suspension platform on panel buildings and allows the use of this platform in a wider range. (Reduced limitation due to wind swing.) OF THE INVENTION, the panels and the remaining angles of the brackets form support arms defining the depth of insertion of the spacer arms into the joint and carrying a pair of fixed levers (2) which together form the letter V and are provided at one end with a mandrel, the other in the working position and one of the levers (2) is provided with a steel eye for attachment to the suspension footbridge.
