About the shaft

The partition board 2 is provided with a first gap which is used as an elevator door 3; the side wall of the well 1 is provided with a bar penetrating hole 6 which penetrates up and down. The rib insertion hole 6 may be provided only in the side wall of the hoistway 1. The partition plate 2 may be provided with a rib-penetrating hole 6 penetrating vertically. Thereby enhancing the coupling strength at the separator 2. The rib penetrating holes 6 on the partition board 2 are positioned at two sides of the elevator door. The part above the first gap is preferably not provided with the rib penetrating hole 6. It is also possible to provide the side walls of the corridor with reinforcement holes 6, in particular if one side wall is provided in each of the front and rear directions of the corridor.

About vestibule

Detailed description of example 1, see FIG. 1

The vestibule is provided with a roof 4, the periphery of the roof is only provided with a downward flanging 5, and no side wall is additionally arranged. The turn-ups can effectively increase vestibule and well 1's joint strength. The lower terminal surface of turn-ups is preferred to flush with the up end of first breach to when making whole pleasing to the eye, shelter from the top part of first breach, reduce the probability that the rainwater got into the vestibule. The portions of the cuff in both the front and rear directions of the top are preferably turned outward. Thereby with the outside of rainwater direction vestibule, further reduce the probability that the rainwater got into the vestibule.

Detailed example 2, see FIG. 2

The vestibule is equipped with preceding lateral wall and back lateral wall respectively in front and back two directions. The front side wall and the rear side wall can be provided with the windows 8 or not. When a window 8 is provided in each of the front and rear side walls, the two windows are preferably opposed to each other. Thereby making the airflow smoother. The vestibule can be provided with only side walls without a roof. And after the installation is finished, pouring the bottom of the corridor at the later stage.

The corridor can be provided with no side wall at the left side or a side wall at the left side, but the side wall at the left side is preferably provided with a second notch 9, so that the corridor is communicated with a building which is pre-provided with an elevator by utilizing the second notch 9, and people can enter the corridor and pass through the corridor to reach the elevator door.

In both embodiments, the top end face of the corridor is flush with the upper end face of the corridor and the side wall of the hoistway 1.

Example 3, see FIG. 2

The vestibule may not have a roof. Only a directional frame-like structure. Firstly, stacking and building up the steel plates up and down, and then building up the steel plates on site. In this case, the built-up roof may allow attachment to a preform located relatively above and partially to a preform located relatively below, so that the roof may be used to increase the strength of the attachment between the upper and lower adjacent preforms.

About the foundation reinforcement 10 and the reinforcement penetrating hole 6

The foundation steel bars are formed by staggering transverse steel bars and longitudinal steel bars, and the transverse steel bars and the longitudinal steel bars are welded at staggered points. Preferably, part of the transverse reinforcing bars extend through the hoistway 1 and the vestibule. The reinforcing steel bars penetrating through the well 1 and the corridor are used as long reinforcing steel bars 7, and at least one long reinforcing steel bar is respectively arranged on the upper part in front of the hollow concrete precast block and the upper part in the rear of the hollow concrete precast block. The long steel bar 7 is an integral steel bar and is a complete one without a connecting point in the middle. One end of the long steel bar 7 on the side of the corridor can extend out of the corridor and be bent into a hook shape. Thereby facilitating connection with the reinforcing bars in the wall of the building. Besides the welding method is adopted to connect the transverse reinforcing steel bars and the longitudinal reinforcing steel bars, the method of bundling the reinforcing steel bars can also be used to replace the welding. It is further preferable that the long reinforcing bar is n-shaped, passes through the upper part of the front of the corridor, the upper part of the front of the hoistway 1, the upper part of the right side of the hoistway 1, the upper part of the rear of the hoistway 1, and the upper part of the rear of the corridor at one time, extends out from the left side of the corridor at both ends, and the extending parts are bent into hook shapes. Preferably, at least two long reinforcing bars are positioned in the same height. Still further preferably, the number of the long steel bars positioned at the upper part in the hollow concrete precast block is at least four. And at least two of them are different in height.

A metal pipe is arranged in the reinforcement penetrating hole 6. Thereby when avoiding the concrete prefabrication, block up and wear the muscle hole, improve the intensity of wearing muscle hole department simultaneously. The metal tube is preferably a metal bellows tube, a metal mesh tube, or the like. The metal tube has certain flexibility and elasticity, and can effectively relieve the problem of metal tube fracture caused by expansion with heat and contraction with cold. Or a strip-shaped groove extending along the axial direction is arranged on the inner wall of the metal pipe, and the notch of the strip-shaped groove faces the inner side. Utilize bar groove release deformation, bar groove plays carminative effect when inserting when wearing the muscle reinforcing bar and inserting the cement mortar behind wearing the muscle reinforcing bar and when pouring, can make the entering between them more smooth and easy. After the cement mortar is poured, the cement mortar entering the strip-shaped groove can also increase the mutual connection strength.

During construction, prefabricated parts are manufactured in a prefabricated field, the manufactured prefabricated parts are transported to the site and stacked up and down, after stacking, the rib penetrating holes are aligned up and down, rib penetrating reinforcing steel bars penetrate into the rib penetrating holes, and cement mortar is injected into the rib penetrating holes after the rib penetrating reinforcing steel bars are in place. After stacking, the tops of the preforms below serve as corridors for the vestibules located relatively above.

In the above embodiments, the inner and outer edges of the upper end surface of the shaft and the partition are preferably provided with upward protrusions 11, and as shown in fig. 3, the inner and outer edges of the lower end surface of the shaft and the partition are preferably provided with recesses matching with the protrusions. So that the lower end of the preform located relatively above is inserted into the projection of the preform located relatively below, thereby restricting the relative position therebetween. The projections 11 may be higher than the level of the upper end surface of the vestibule.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
