An elevator shaft wall assembled by a combined derrick

Abstract

The invention discloses an elevator shaft wall assembled by a combined derrick, and relates to a hoisting device. The well wall includes a metal structure well tower and a bottom pit body. The well tower includes more than two interconnected derricks, and the bottom of the well tower is fixed on the bottom pit body by high-strength bolts. Each of the derricks includes 4 columns, at least 1 front beam and door beam, at least 2 rear beams, at least 2 left side beams and right side beams, the columns are distributed at the four corners of the derrick, and the top and bottom ends of the columns are A connection seat is provided, and at least two connection holes are provided on the connection seat, and the two ends of the front beam, the door beam, the rear beam, the left side beam and the right side beam are respectively connected to the column horizontally. The combined derrick of the present invention can be produced standardizedly in the factory and assembled on site, which is beneficial to shorten the construction period, save costs, reduce the cost, improve the installation efficiency and installation quality, and can reduce the impact of the installation of elevators on the ventilation and lighting of residents. The main application place of the present invention is the old-fashioned low-rise residence below 9 floors.

Description

technical field [0001] The invention and creation title of the prior application of the present invention is "an elevator assembled by a combined derrick", the application number is ZL201120001100.8, and the application date is January 4, 2011. [0002] The present invention relates to a hoisting device, in particular to an elevator. Background technique [0003] The well of the existing elevator is the space provided for the operation of the car and the counterweight, and the space is bounded by the bottom of the well pit, the well wall and the well top. The hoistway is surrounded by hoistway walls, which are used to install elevator components such as car guide rails and counterweight guide rails, and to separate walls or structures between the hoistway and other places. Since most of the old-style low-rise residences did not consider the installation of elevators, it is necessary to build a new well wall when installing an elevator. The new well wall is bounded by the gr...

Problems solved by technology

[0006] In view of the above-mentioned defects existing in the existing elevator shaft wall, the object of the present invention is to provide an elevator shaft wall assembled with a combined derrick. The hoistway wall assembled with a combined derrick can shorten the construction period, save costs, reduce the cost, and is beneficial to solve the problem of ventilation. The problem of light transmission can improve the installation efficiency and quality of the elevator; the pit construction technology of the present invention has high efficiency and short construction period, which is beneficial to reduce the impact of pit construction on the daily life of residents
