Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a hoistway for a residential elevator that is installed to allow elevators to move up and down between the first floor and the top floor (second or third floor) of a private residence.

[Conventional technology]

In recent years, due to the aging of society and the housing situation, houses have become more three-dimensional, and two- and three-story private residences have become commonplace. In the case of such two- and three-story private residences, climbing up and down stairs becomes a new burden for families with elderly people with reduced physical function or people with physical disabilities. Under these circumstances, elevators for private residences have recently been developed with the intention of improving the convenience of living by enabling the vertical movement of people and objects in two- and three-story private residences.

[Problem that the invention attempts to solve]

By the way, when installing an elevator in the above-mentioned private residence, a hoistway long enough to reach from the ground floor of the first floor to above the ceiling of the top floor is installed inside the house, and along this hoistway, cars (cars) for carrying people and objects are installed. However, the elevator hoistways that have been developed in the past are made of steel members that are assembled by welding at the installation site, so installation work is difficult. The problem was that it took several days to install one elevator. Therefore, with the intention of simplifying the installation of the hoistway, square pipe supports were erected at the four corners, and a required number of crossbeams and bracing members were installed between these supports to form a rectangular hoistway that extends vertically. However, in this case, if the support is a single-length through member, the length of each support becomes long, which is inconvenient for transportation and assembly.

[Means to solve the problem]

This invention was proposed in response to the above-mentioned problem, and when a hoistway is constructed by erecting pillars made of square pipes at the four corners, welding is not required at all when assembling the hoistway. The aim is to provide a hoistway that is devised so that the supports can be divided into sections, and the transportation and installation work can be greatly simplified. The idea is structured as follows. In other words, the present invention constructs a hoistway for a residential elevator by erecting pillars made of square pipes at the four corners and installing the required number of crossbeams and bracing members between each pillar. A first square pipe joint fitting having an inner diameter that can be slidably inserted into the square pipe, and a second square pipe joint fitting having the same inner diameter and a partition wall formed inside the middle in the cylindrical direction of the square pipe in the required number. The first and second square pipe joint fittings are provided with fitting portions for fitting the ends of the cross beams, and hooks for locking the ends of the bracing members, and The pillars erected at the four corners are connected in multiple stages through joint fittings made of square pipes to form the required length, and the first A cross beam is installed between the columns through the respective fitting parts of the opposing joint brackets, and a cross beam is installed between the columns via the hooks of the lower joint bracket and the upper joint bracket located diagonally. A bracing member is installed on the roof.
