The connecting platform can be folded and stowed during transportation, and unfolded when the hoisting is complete to serve as a connecting corridor between the elevator shaft and the existing residential opening side. A lifting hole is arranged on the top of the elevator shaft module as a lifting point. If there are two elevator shaft modules, a lifting hole is arranged on the end of one of the sections away from the foundation pit connection end as a lifting point.

[0005] Preferably, the connecting platform is a steel beam structure, and the steel beam is hinged to the frame for flipping arrangement.

[0006] Preferably, reinforcing ribs are fixed to the lower portion of the steel beam on the opening side of the U-shaped frame.

[0007] Preferably, an embedded steel plate is provided on the opening side of the existing residence, a connecting plate is fixed on the embedded steel plate, the connecting plate is butt-jointed with the flipped steel beam to form the basis of the connecting corridor, and the production of the steel beam and the production of the connecting plate are matched and designed in advance.

[0008] Beneficial effects:

[0009] The utility model adopts the above technical solution, by setting up a pre-installed elevator shaft module, during transportation, the pre-installed elevator shaft module is horizontally placed on the transport vehicle, the steel beam is flipped and folded, and then hoisted to the corresponding, after the vehicle arrives at the destination, the horizontal pre-installed elevator shaft module is connected to the hoisting equipment, hoisted to a vertical state, the steel beam is unfolded, and the connection and installation with the existing residential opening are carried out. The utility model structure installs the steel structure elevator shaft and the connecting corridor foundation at the same time, shortens the working cycle, ensures the consistency of the on-site assembly and design of the shaft frame, and is convenient for transportation and hoisting installation.

[0019] Specific embodiments of the utility model:

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5An assembled elevator shaft hoisting structure of the present embodiment includes two sections of pre-installed elevator shaft modules, each of which is a U-shaped frame 1. A reversible connecting platform is arranged on the opening side of the U-shaped frame. The connecting platform can be folded and stowed during transportation, and unfolded when the hoisting is complete to serve as a connecting corridor between the elevator shaft and the existing residential opening side. A lifting hole is arranged on the top of the elevator shaft module as a lifting point, and a lifting hole is arranged at one end of one section away from the foundation pit connection end as a lifting point 3.

[0021] Preferably, the connecting platform is a steel beam structure, the steel beam 2 is hinged to the frame for flipping arrangement, in the embodiment, the steel beam and the frame column are connected by hinges 8, and cross beams 7 are arranged between the steel beams.

[0022] Preferably, a reinforcing rib 4 is fixed to the lower portion of the steel beam on the opening side of the U-shaped frame.

[0023] Preferably, an embedded steel plate 5 is provided on the opening side of the existing residence, a connecting plate 6 is fixed on the embedded steel plate, and the connecting plate is butted with the turned-over steel beam to form the basis of the connecting corridor, and the production of the steel beam and the production of the connecting plate are matched and designed in advance.

[0024] The working process of the utility model is as follows:

[0025] See also Figure 6 , Figure 7 The aisle steel beam is fixed to the A side of the shaft module by a hinge. The steel beam is folded and put away during transportation. After being transported to the installation site, the section shaft is fixed and lifted by a crane with a lifting point. It is lifted vertically and slowly. The steel beam slowly unfolds due to gravity. After one end of the shaft rises to a certain height and forms an elevation angle, the steel beam is fully unfolded. The shaft and corridor foundation are hoisted to the designated installation position as a whole. The embedded steel plates and connecting plates are fixed at the existing residential openings. After completing the hoisting of one section of the shaft module, the second section of the shaft module can be hoisted into place in the same way.

[0026] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
