Detailed Description

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

As shown in fig. 1 and 2.

A prefabricated concrete foundation with an external elevator comprises a raft 1 and a cylinder 2. The raft plate 1 is flat and can be horizontally placed on a foundation. The raft 1 is square or other shapes so as to meet the requirements of different environments. The size of this raft board 1 and foundation bearing capacity looks adaptation, its thickness, arrangement of reinforcement suit with the load of elevator to can satisfy the operation demand of elevator. Raft steel bars 1-1 are also arranged in the raft 1, so that the bearing requirements of the raft can be met.

The barrel 2 is a square frame body and is arranged on the raft plate 1 in the middle. This barrel 2 accessible cast in situ concrete mode set up in raft 1 upper surface can block the outside soil of this barrel 2 to the groundwater that prevents infiltrates in its enclosed elevator foundation ditch. Preferably, the steel bar structure further comprises a plurality of vertical steel bars 2-1. The lower part of the vertical steel bar 2-1 is arranged in the raft 1, and the upper part is arranged in the cylinder 2, so that the cylinder 2 is firmly connected with the raft 1. The vertical steel bars 2-1 are in a shape like a Chinese character 'ji' or a shape like a Chinese character 'kou', so that the cylinder body is firmly connected with the raft plate 1.

Four pre-buried steel plates 6 are arranged in a foundation pit surrounded by the cylinder 2. This pre-buried steel sheet 6 is fixed in the upper surface of raft 1 to close on four bights of barrel 2 can link to each other with elevator well 3, make the firm standing of elevator well 3 on the raft 1. Preferably, a plurality of tie bars 6-1 are welded on the bottom surface of each embedded steel plate 6. The tie bars 6-1 are arranged in the raft plate 1, and the lower ends of the tie bars are bent inwards or outwards, so that the tie bars can be firmly connected with the raft plate 1, and the embedded steel plates 6 are effectively prevented from being pulled and separated from the raft plate 1.

Four symmetrically arranged hanging rings 4 are arranged on the raft plate 1, so that the lifting is convenient. The suspension ring 4 is shaped like a Chinese character 'ji', 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 for the hoisting rigging to be bound and hung.

The utility model discloses still include stagnant water board 5. The water stop plate 5 is frame-shaped, and the shape and the size of the water stop plate are adapted to the cylinder 2. This water stop plate 5 vertical set up in between barrel 2 and raft 1, and bury underground in barrel 2, can prevent groundwater in the peripheral soil of barrel 2 from permeating in the foundation ditch of barrel 2 enclosure.

When in use, the raft plate can be cast in a factory. When the prefabricated raft is manufactured, the embedded steel plates, the vertical steel bars, the water stop plates, the hanging rings and the like can be simultaneously installed on the raft, and pouring is carried out together. And then, transporting the prefabricated raft to a construction site, hoisting the raft on a foundation on the site by using a crane, and aligning and fixing the raft. 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 on the embedded steel plates.

The utility model discloses a separate raft and barrel, make the weight of raft very alleviate, convenient transportation and hoist and mount. Meanwhile, the position of the embedded steel plate is staggered with the position of the barrel, so that barrel construction and installation of an elevator shaft can be synchronously carried out on a construction site, the construction period is greatly shortened, the influence on the environment is reduced, and the barrel only bears the soil pressure all around and can be thinned appropriately to save materials.

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.
