Embodiment Construction

[0022] The technical solutions of the present invention will be described in further detail below with reference to the drawings and specific implementations, but the present invention is not limited to these embodiments.

[0023] Such as figure 1 , figure 2 As shown, the steel structure elevator hoistway assembly of the present invention includes: an upper frame 1, a lower frame 2 and a connecting piece. The upper frame 1 and the lower frame 2 are fixedly connected by the connecting piece; the upper frame 1 includes a plurality of vertical The installed square steels are fixedly connected to each other by connecting steel 15; the side of the connecting steel is provided with a through groove 151 and an installation opening 152 perpendicular to the through groove. The lower frame 2 and the upper frame 1 are arranged symmetrically; the upper frame 1 and the lower frame 2 have the same structure and composition, and the upper frame and the lower frame are interchangeable during th...

Abstract

The invention discloses a steel structure elevator shaft assembly. The steel structure elevator shaft assembly comprises an upper frame, a lower frame and connecting parts. The upper frame and the lower frame are fixedly connected through the connecting parts. The upper frame comprises a plurality of square steels arranged vertically. The square steels are fixedly connected through connecting steels. The side faces of the connecting steels are provided with slots and mounting ports perpendicular to the slots. The steel structure elevator shaft assembly has the advantages that the upper frame and the lower frame are connected reliably, the connection mode of the connecting steels is simple, and the machining amount is little.

Description

Technical field [0001] The invention relates to the technical field of elevators, in particular to a steel structure elevator shaft assembly. Background technique [0002] Elevators are the main means of vertical transportation in the building; the hoistway is the space where the car and counterweight move. The existing hoistway structure is mainly divided into concrete hoistway and steel structure hoistway. If brick wall reinforced concrete structure hoistway is directly laid on the construction site, it is not economical and takes up a lot of space. A steel structure hoistway is formed by integral field welding or field welding of prefabricated steel components, which requires high-altitude welding technology and is difficult to construct. The other kind of steel structure hoistway is fully assembled, all of which are made of single prefabricated steel components, which are fastened by bolts on site. This kind of steel structure hoistway saves the trouble of high-altitude wel...
