Description

A piece-type shaft standard section of quick-installed steel structure elevator for old buildings

technical field

The invention relates to a piece-type shaft standard section of a quick-installed steel structure elevator for an old building, and belongs to the technical field of elevators.

Background technique

With the intensification of population aging and high property prices, it is imperative to install elevators in old buildings. At the same time, this is also a livelihood project advocated and encouraged by the government, and the market potential is huge. Because there is no shaft installed in the old building, the usual solution is to use a steel structure as the shaft and install it outdoors. The shaft of the quick-installed steel structure elevator in the old building adopts a standard section design, and the standard sections are connected to form a shaft. , so the standard section is the key stress member of the steel structure well.

The assembly of the existing steel structure hoistway is carried out by large vehicles to transport various components including the standard section to the site for installation. Since the standard section is made according to the standard, each standard section occupies a large volume, which greatly increases the transportation cost.

Contents of the invention

The purpose of the present invention is to overcome the disadvantages of the prior art and provide an assembled shaft standard section with relatively simple structure, convenient and fast installation and use, good structural rigidity and reduced transportation cost.

The present invention is achieved through the following technologies:

The invention provides a piece-type shaft standard section of a quick-installed steel structure elevator in an old building. It is mainly composed of four standard sections connected in sequence. The four standard sections have different structures: one piece includes a main limb, two Cross bar, two door posts, two cross bars are placed horizontally and one end is connected to the main leg, and the door post is installed between the two cross bars; one piece includes a main leg, two cross bars are placed horizontally and one end is connected to the main leg , T-shaped guide rails for the car are installed on two cross bars; one piece includes a main leg, two cross bars are placed horizontally, and one end is connected to the main leg; one piece includes a main leg, two cross bars are placed horizontally, and one end Connected with the main limb, a car-counterweight shared guide rail frame is installed on each of the two cross bars. Two hollow guide rails for counterweight are installed inside the circle formed by the guide rail frame and the cross bar, and a car is installed parallel to the bar on the outside. T-shaped guide rail for carriage; a connecting piece matching another piece of standard section crossbar is installed on the main limb.

The main limb of the present invention is a square tube, one end of which is provided with a sleeve composed of two bent plates, and the other end is provided with a connecting hole for connecting the sleeve composed of two bent plates; the angle of each bent plate It is 90° and just fits with the main limb. There are three holes on each of the two vertical plates of the bent plate. The holes on different plates are not in the same vertical plane and are not affected by each other when connected; the setting of this component greatly improves The assembly speed of the steel structure shaft of the elevator.

The connecting piece of the present invention is used to connect the main limb of a standard section and the cross bar of another matching standard section. One end of the connecting piece is buckled on the main limb and connected with the main limb through bolts. The connecting piece The other end is fastened to the cross bar of another standard section and connected by bolts, so as to realize the connection between the main leg and the cross bar; and each connection point uses two connecting pieces, and the connecting piece is between the main There are ribs on the corners of the rod connection, which greatly increase the rigidity and stability of the standard joint.
