Description

A PROTECTION DECK GUIDE BRACKET, A PROTECTION DECK AND A METHOD FOR GUIDING A PROTECTION DECK
FIELD OF THE INVENTION
The invention relates to a protection deck guide bracket, a protection deck, and a method for guiding a protection deck in an elevator shaft. The invention relates in particular to construction time protection of persons and/or components located in a lower portion of a shaft of an elevator. The elevator is preferably an elevator for transporting passengers and/or goods.
BACKGROUND OF THE INVENTION
When an elevator or a building surrounding it is under construction, there may be installation workers in the lower parts of the elevator hoistway carrying out construction work. Also, the lower parts of the hoistway may already be in construction-time transport use. During construction, there is an increased risk of objects falling into the lower parts of the hoistway. For example, tools or construction material may fall into the hoistway. Persons and components located in the lower parts of the hoistway must be protected from falling objects.
The construction of an elevator may especially in high-rise buildings be done in parts along the height of the hoistway. The guide rails and the landing doors may first be installed to a first height in the hoistway, then to a second height etc. A construction time elevator may then be operated on the already installed lower portion of the hoistway while the construction of the elevator is going on in a higher portion of the hoistway.
One known technique to improve construction process efficiency is a construction-time use CTU elevator with a temporary machine room that can be moved, in other words jumped, upwards as construction progresses. The CTU elevator, such as a jump-lift, enables a faster and safer construction process, earlier closing of the facade, reduced down-time, and safer transportation in all weather conditions. The construction-time elevator enables that construction of the elevator hoistway and elevator installations may continue at higher floors while the elevator is already operating in the same elevator hoistway at the lower floors, below a protection deck.
The protection deck above the elevator allows the use of the elevator during construction-time and protects the running elevator.
A construction-time elevator system may comprise protection decks on top of each other at a distance from each other. When the structure of the building rises, the protection deck is moved a few floors up.
There is a need for an improved solution for preventing undesired movement of the protection deck in the elevator shaft and to lock the protection deck to its desired location.
SUMMARY OF THE INVENTION
An object of the present invention is to introduce an improved protection deck guide bracket, an improved construction arrangement of an elevator and an improved method for guiding a protection deck in an elevator shaft. The invention provides solutions relating to problems associated with installing an elevator during construction of a building.
The protection deck guide shoe according to the invention is defined in claim 1. The protection deck guide bracket comprises: a guide part between an elevator guide rail and a protection deck in an elevator shaft, the guide part being movably supported on said guide rail; and a clamp part connected to the guide part, configured to lock the guide bracket to said guide rail in a position in relation to said guide rail.
Preferable further details of the invention are introduced in the following, which further details can be combined individually or in any combination.
According to an embodiment the guide part comprises a guide shoe slidable along the guide rail, or a guide roller rollable along the guide rail.
According to an embodiment the guide shoe comprises a sliding groove, preferably arranged in a sliding element, receiving the guide rail.
According to an embodiment the guide bracket comprises a horizontally extendable and retractable actuator supporting the guide shoe or the guide roller.
According to an embodiment the guide part is configured to support the guide bracket on the guide rail when the guide bracket is moved along the guide rail.
According to an embodiment the guide bracket comprises a fixing interface attachable to the protection deck.
According to an embodiment the fixing interface is movable along a frame of the protection deck when the position of the frame is adjusted in relation to a stationary structure of the shaft. According to an embodiment the clamp part is configured to lock the guide bracket in a predefined height position in the shaft when the protection deck is installed with at least one guide bracket in the shaft.
According to an embodiment the clamp part comprises a locking groove receiving the guide rail. According to an embodiment the clamp part comprises two opposite locking surfaces between which the guide rail is clamped.
According to an embodiment the clamp part comprises a stationary jaw having a first locking surface and a movable jaw having a second locking surface. According to an embodiment the stationary jaw and the movable jaw provide for opposite sides of the locking groove.
