SU1218030A1 - Movable scaffold - Google Patents

Description

The invention relates to the construction of bridges, namely the construction of bridges with beam beams with orthotropic roadway plates.

The aim of the invention is to ensure the movement of the scaffolding along the inclined lower along the beam span structures of varying height.

FIG. 1 depicts movable scaffolding from the facade; in fig. 2 - the same side; in fig. 3 is a section A-A in FIG. 2 (a node leaning the scaffolding on the bottom of the main beam); in fig. 4 - tower leaning unit on the scaffolding); in fig. 5 - the sliding node of the tower in the direction of their rollers of the scaffolding.

The movable scaffolding consists of a lower working plate, adki 1 with guide rollers 2 and support dogs 3 located in the sliding assembly of the tower 4 with upper working platforms 5.

The scaffolds rest on the lower shelf of the main beams of the superstructure through brackets 6, support beams 7 and chassis carts 8. To prevent the spontaneous movement of the scaffolds to the side of the slope, there are persistent shanks 9 and a screw stop 10. To extend the bastens, two manual winches 11.

Work with scaffoldings is carried out both from the lower working platform 1 and from the upper working platform 5. When the height of the main beams of the superstructure is changed, the platform is extended (lowered)

using manual winches 11 located on the lower working platform 1. The scaffolding is moved along the span structure by winches located on both the scaffolding itself and on the bridge supports.

Claims (1)

MOBILE SCALES for servicing the inter-farm space with beam spans, including a supporting work platform, telescopic beams fixed with the possibility of vertical movement with additional work platforms and guides, characterized in that, in order to ensure the movement of scaffolds along the inclined lower belts of variable beam spans heights, scaffolds are equipped with self-supporting supporting brackets with running trolleys located on an inclined lower belt of the beam, and locking devices made in the form of rods with screw stops. figl Scaffolds based on the shelf bottom flange of the main beams of the superstructure via the brackets 6, the supporting beams 7 and 8. For driving the trolley prevent ca ₅ moproizvolnogo move towards bias scaffolding at sites are thrust rod 9 and the stop screw 10. In extension towers two hand winch mounted eleven. Work with scaffolds is carried out both from the lower working platform 1 and from the upper working platform 5. When changing the height of the main beams of the superstructure, the towers are extended (lowered) using hand winches 11 located on the lower working platform 1. Moving the scaffolds along the superstructure carried out by winches located both on the scaffolds themselves and on the bridge supports.
