Additional elevator gallery bridge assembly and installing method thereof

Abstract

The invention relates to an additional elevator gallery bridge assembly which comprises a shaft support seat, a gallery plate and a building support seat, wherein the gallery plate is a prefabricatedreinforced concrete hollow plate; force bearing shafts are respectively arranged at two ends of the two side edges of the gallery plate; the shaft fixed support seat is fixed on an elevator shaft; a first groove with an upward opening is formed in the shaft support seat; the building support seat is fixed on the existing building wall body; a second groove with an upward opening is formed in the building support seat; each of the longitudinal profile of the first groove and the longitudinal profile of the second groove is in a bell mouth shape; the bottom of the first groove is in a semicircular shape with the diameter identical to the diameter of the force bearing shaft, so that the force bearing shaft can rotate in the first groove; the bottom of the second groove is in a shape of a halflong circle; and the transverse distance of the second groove is greater than the diameter of the force bearing shaft, so that the force bearing shaft can rotate and transversely move in the second groove. The additional elevator gallery bridge assembly has the advantages that the weight of the gallery plate can be reduced; the transportation and the installation are convenient; the adverse influence of the shaft on the building structure can be reduced; and beneficial conditions are created for the safe operation of an additional elevator.

Description

technical field [0001] The invention relates to an elevator facility, in particular to an elevator bridge assembly and a construction method thereof, in particular to an elevator bridge assembly and an installation method thereof. Background technique [0002] With the arrival of my country's aging society, existing multi-storey residential buildings and office buildings need to add additional elevators so that the elderly can live and work. Building an additional elevator shaft frame and corridor next to the existing building, such as using the traditional construction method of cast-in-place concrete or welded steel structure, not only has problems such as long construction period, low work efficiency, fire hazard, environmental pollution, waste of materials, etc. And it is easy to interfere with the use of existing buildings, and cause many conflicts with building residents. At present, the elevator shaft has been basically prefabricated, but the bridge slab for walking ...

AI Technical Summary

Problems solved by technology

Building an additional elevator shaft frame and corridor next to the existing building, such as using the traditional construction method of cast-in-place concrete or welded steel structure, not only has problems such as long construction period, low work efficiency, fire hazard, environmental pollution, waste of materials, etc. And it is easy to interfere with the use of existing buildings, and cause many conflicts with building residents

At present, the elevator shaft has been basically prefabricated, but the bridge slab for walking between the shaft and the building still adopts cast-in-place technology, and its two ends are fixed with the building and the elevator shaft, which makes the uneven settlement of the shaft , unfavorable factors such as wind load are transmitted to the existing building structure through the corridor bridge slabs fixed at both ends, which may have many unsafe effects on the building structure. Therefore, it is necessary to design an elevator that can reduce the impact on the building structure Attached load, fast construction, easy on-site management, and high assembly rate are added to the elevator corridor bridge plate to meet the needs of the market
