Coaxial and double-beam shared supporting structure without machine room

Abstract

The invention discloses a coaxial and double-beam shared supporting structure without a machine room, which comprises a supporting assembly and fastening plates, wherein the supporting assembly comprises a bearing part and stopping parts, the bearing part is fixedly arranged on the upper surface of a middle beam, and the stopping parts are arranged on two opposite sides of the bearing part; butt-joint end parts of two main machine supporting beams are fastened by the fastening plates, are fixedly arranged on the bearing part of the supporting assembly and are also fixedly stopped by the stopping parts on the two opposite sides of the bearing part, the length direction of the bearing part extends in the transverse direction of the middle beam, and the two ends of the bearing part extend out of the middle beam, so that the bearable contact area of the bearing part is larger than the width of the middle beam, the erecting contact area of the end parts of the main machine supporting beams is increased, and the requirements of the contact area are met; and therefore, by matching with the stopping function of each stopping part, the erecting stability of each supporting beam is remarkably improved.

Description

technical field [0001] The invention relates to a shared support structure of machine room-less coaxial double beams. Background technique [0002] Two machine-room-less elevators are connected in parallel and share the erection of the main beam on the top floor of the shaft. Because the two elevators share a shaft, and there are only a few steel beams in the middle of the shaft to separate the spaces of the two elevators, one end of the supporting beams of the two hosts needs to share the steel beam in the middle to fix them. When it is fixed on the middle beam, it will be found that the width of the middle beam cannot meet the requirements of the contact area erected by the two supporting beams. Contents of the invention [0003] The purpose of the present invention is to provide a shared support structure in which the machine room-less coaxial double girders are supported and fixed by support members, which increases the erection contact area at the end of the main eng...
