Description

Technical Field

[0001] The utility model belongs to the field of elevator pits, and particularly relates to an elevator pit structure and a building. Background Technique

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] For vertical elevators with steel structure hoistways, the design of steel column footings and short reinforced concrete foundation columns cannot be avoided. According to the requirements of relevant codes and manuals, the cross-sectional dimensions of short reinforced concrete foundation columns are often larger than those of steel columns, resulting in the situation that the elevator car collides with the short foundation column during maintenance installation or accident conditions.

[0004] The reasons for this situation are as follows:

[0005] (1) From the perspective of elevator manufacturers, the closer the car is to the hoistway (i.e., the steel column), the easier it is to handle the opening side of the car (i.e., the floor platform is directly in front of the opened door).

[0006] (2) From the overall building plan, the location and occupied area of the elevator shaft are often restricted. There are many underground foundations around the elevator shaft. In order to avoid collisions, the size of the hoistway cannot be enlarged arbitrarily.

[0007] For ordinary or low-height elevator hoistways, the conventional method is to lower the top elevation of the foundation short column according to the requirements of the elevator manufacturer to solve the collision problem. However, for very high elevator hoistways, according to the manufacturer's requirements, the top elevation of the foundation short column often needs to be lowered a lot, and the bottom elevation of the steel column also needs to be lowered accordingly, resulting in a situation where the height of the bottom layer of the steel column is too high and the calculation fails. To solve the calculation problem, it is necessary to add an intermediate beam or column bracing at the bottom layer of the steel column, and at this time, there will be a situation where the intermediate beam or column bracing collides with the side wall of the pit. Summary of the Invention

[0008] In order to solve the above problems, the utility model provides an elevator pit structure and a building, which can solve the problems of the car colliding with the foundation short column and the intermediate beam or column bracing colliding with the side wall of the pit.

[0009] According to some embodiments, the utility model adopts the following technical solutions:

[0010] An elevator pit structure includes a raft foundation, and a stepped structure is arranged on the upper part of the raft foundation. The first layer is the part from the top of the foundation to the top of the foundation short column, and the second layer is the part from the top of the foundation short column to the top of the pit.

[0011] Among them, the part from the top of the foundation to the top of the short foundation column includes four first side walls that are sequentially connected to form a rectangle, and a reinforced concrete short foundation column is provided at the connection of two adjacent first side walls;

[0012] The part from the top of the short foundation column to the top of the well pit includes four second side walls that are sequentially connected to form a rectangle, and elevator steel columns are provided along the inner edge at the connection of two adjacent second side walls;

[0013] The thicknesses of the first side wall and the second side wall are different.

[0014] As an alternative implementation manner, the second side wall is disposed on the corresponding first side wall.

[0015] As an alternative implementation manner, the thickness of the first side wall is greater than the thickness of the second side wall.

[0016] As an alternative implementation manner, the outer walls of the first side wall and the second side wall are flush.

[0017] As an alternative implementation manner, the thickness difference between the first side wall and the second side wall provides space for the floor beam or the inter-column bracing.

[0018] As an alternative implementation manner, the reinforced concrete short foundation column is rectangular and covers a part of two adjacent first side walls.

[0019] As a further aspect, the width and height of the reinforced concrete short foundation column are both greater than the thickness of the first side wall.

[0020] As an alternative implementation manner, the elevator steel column is an H-shaped steel.

[0021] As an alternative implementation manner, both the first side wall and the second side wall are disposed below the top of the well pit.

[0022] A building includes the above elevator well pit structure.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0024] In the present utility model, the thickness of the well pit side wall (i.e., the first side wall) below the top of the short column is A, and the thickness of the well pit side wall from the top of the short column to the ground (i.e., the second side wall) is B, and B is less than A. The thickness difference of the well pit side wall provides space for the floor beam or the inter-column bracing, and can solve the problems of the car colliding with the short foundation column and the floor beam or the inter-column bracing colliding with the well pit side wall.
