Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1-5.

A prefabricated assembly type additional elevator foundation structure comprises a raft plate 1, a cylinder body 5, steel supporting legs 2 and the like. The raft plate 1 is flat and can be horizontally arranged on a foundation. The raft 1 is square or of other shape to suit different environments. The raft 1 is made of concrete and is internally provided with a reinforcement cage 6 so as to increase the strength thereof. The raft 1 has a size adapted to the bearing capacity of the foundation, and a thickness and reinforcing bars adapted to the load of the elevator. The raft plate can be prefabricated in a factory.

The barrel 5 is a square frame body and is arranged on the raft 4 in the middle. The cylinder 5 can be arranged on the upper surface of the raft 1 in a concrete cast-in-place mode, so that the soil outside the cylinder 5 can be blocked, and underground water can be prevented from permeating into an elevator foundation pit surrounded by the cylinder. Preferably, a plurality of sets of vertical reinforcing bars 4 are also included. The lower part of the vertical steel bar 4 is arranged in the raft 1, the upper part of the vertical steel bar is arranged in the cylinder 5, and the cylinder 5 is firmly connected with the raft 1 by pouring concrete.

The four steel supporting legs 2 are all in a column shape with a square cross section and are respectively arranged at four inner corners of the barrel body 5. The steel support legs 2 are perpendicular to the raft 1, the lower ends of the steel support legs are arranged in the raft 1, the upper ends of the steel support legs are provided with pore plates 2-1, and the elevator hoistway can be installed on the pore plates 2-1 through bolts. Preferably, the lower end of the steel leg 2 is provided with a bottom plate 2-2 which can play a role in resisting pulling.

The plane of the foundation pit surrounded by the cylinder 5 is square and can be adapted to the shape of the elevator. The cylinder body can wrap the steel support leg, and armpit angles 5-1 are arranged at four inner corners of the cylinder body, so that the inner corners of the cylinder body 5 can be reinforced, and the steel support leg 2 can be supported and protected.

Furthermore, a plurality of symmetrically arranged hanging rings 7 are arranged on the raft plate 1, so that the lifting is convenient. The hanging ring 7 is long arch-shaped, the lower part is arranged in the raft plate 1, and the upper part is arranged outside the upper surface of the raft plate 1, so that the hoisting rigging is convenient to tie and hang. Preferably, the lower end of the hanging ring 7 is bent outwards, so that the pulling resistance of the hanging ring during bearing can be improved.

Further, the water-stop plate 3 is also included. The water stop plate 3 is frame-shaped, is adapted to the shape and size of the cylinder 5, and is arranged on the outer side of the steel leg 2. Simultaneously, this stagnant water board still vertical set up in between barrel 5 and raft 1 can prevent the groundwater in the peripheral soil of barrel 5 from permeating in the elevator foundation ditch that barrel 5 was encircleed.

When in application, the raft can be cast and prefabricated in a factory. When the raft is manufactured, the steel supporting legs, the vertical steel bars, the water stop plates, the lifting rings and the like can be simultaneously installed on the raft, and pouring is carried out together. And then, transporting the raft component to a construction site, hoisting the raft component on a foundation on the site by a crane, and fixing the raft component after alignment. Meanwhile, the construction of the cylinder body is completed on the raft plate in a cast-in-place mode, and the elevator shaft can be synchronously installed at the upper ends of the steel supporting legs.

The utility model discloses a separate raft and barrel, make the weight of raft very alleviate, convenient transportation and hoist and mount. Meanwhile, the height of the steel support legs is larger than the upper surface of the cylinder body, so that the cylinder body construction and the installation of the elevator shaft can be synchronously carried out on a construction site, the construction period can be greatly shortened, and the influence on the environment is reduced

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
