10A is a view showing another example in which a conventional structure is installed at the bottom of an elevator pit.

Referring to FIG. 10A, a conventional elevator pit is designed to support a load of a building by a wall, and the load of the wall is transferred to the ground through an elevator bottom structure of a lower part. To this end, a base structure for supporting it at the bottom of the elevator pit should be formed, and at the same time, a space for checking the elevator should be secured.

To this end, a bottom installation groove 1a 'is formed by digging in the bottom surface 1 of the elevator pit, and a conventional elevator pit structure 5 is disposed on the top of the floor installation groove 1a', and the floor installation is performed. Concrete is poured around the groove 1 a ′ and the structure 5 to form a pit support bottom 20. The pit support bottom portion 20 thus formed forms the bottom foundation of the lowest layer that the elevator can reach.

Then, the concrete is poured vertically upward along the outer side of the elevator pit 10 from the pit support bottom portion 20 so that the elevator pit 10 is firmly supported, so that the pit support wall part 30 is formed.

Here, the depth d 'of the floor mounting groove 1a' is a solid that can bear the upward buoyancy applied to the bottom of the elevator pit 10 and the load transmitted downward from the pit support wall portion 30 at the same time. In order to maintain the strength of the structure, it is necessary to dig beyond the depth corresponding to the thickness d of the pit support bottom 20.

However, the excavation of the depth d 'of the floor mounting groove 1a' corresponding to the thickness d of the pit support bottom 20 is cumbersome and consequently a long construction cost and construction period. There is this.

The reinforcement member 800 is located in a plurality of the upper surface of the floor installation groove 10, the concrete 602 is poured in the space located between each reinforcement member 800, the reinforcement member 800 construction site Make sure you have the strong bearing strength required by. In addition, the bottom portion 500 and the mold 700 are sequentially positioned on the upper portion of the reinforcing member 800.

On the other hand, since the elevator pit is located on the basement floor of the building, water is easily introduced to the bottom of the elevator pit because it is easily exposed to flowing water or moisture. In the present invention is configured to further include a drain hole 922, the sump 924 and the drain passage 920 to discharge the water so introduced to the outside.

The drain hole 922 is a through hole formed through the edge portion 501 of the bottom part 500, and flowing water or rain water introduced into the bottom part 500 through the drain hole 922 is discharged to the outside.

The sump 924 is located outside the elevator pit and is provided with a space for receiving running water or rainwater. When the sump 924 is located inside the elevator pit, the sump 924 may be disposed outside the elevator pit because the rigidity of the elevator pit may be weakened due to the space for forming the sump 924.

22 is a view showing another embodiment in which the elevator pit bottom structure of the present invention is installed. Referring to FIG. 22, the bottom structure of the present invention includes a sidewall part 550 and the sidewall of which the collecting well 926 is located inside the elevator pit in FIG. 21, and stands vertically upward on the outside of the bottom part 500. It is further configured to further include a coupling protrusion member 910 protruding from the outside of the portion 550.

In FIG. 21, when the sump 926 is located inside the elevator pit, the rigidity of the elevator pit may be lowered. Thus, the sump 926 is located outside the elevator pit, but in FIG. 22, the sump 926 has a strong strength. Since the reinforcement member 800 is positioned above the floor installation groove 10, the reinforcement member 800 may withstand the upward buoyancy rising from the floor installation groove 10, and may withstand the load applied from the pit support wall part 30. Therefore, even if the sump 926 is located inside the elevator pit, the rigidity of the elevator pit due to the sump 926 is not lowered. As such, when the sump 926 is positioned inside the elevator pit, there is an advantage in that a separate external space for positioning the sump 926 is not required.

In order for the sump 926 to be located inside the elevator pit, the bottom installation groove 10 of the bottom surface 1 of the elevator pit is provided with a sump trough 12 for inserting the sump 926. The size of the sump groove 12 is to be formed larger than the size of the sump 926, the bottom surface of the sump 926 and the sump groove 12 are spaced apart from each other to form a space 940 is formed. It is preferable. The space 940 is configured to fill the space when the concrete is poured into the floor installation groove 10 so that the pit support bottom 20 is formed, or install the collecting well 926. After that, by pouring concrete separately, the space 940 may be filled.

Thus forming the space 940 in the lower portion of the sump 926, when forming the sump groove 12, the sump groove 12 to fit the size of the sump 926 and time and professional Since the equipment does not have to be precisely formed, there is an advantage of shortening the construction period.

23 is a view showing another example in which a conventional structure is installed at the bottom of the elevator pit. Referring to FIG. 23, the elevator pit structure 5 is disposed on the bottom surface 1 on which the building is constructed. In order to arrange the lower end of the structure 5 on the bottom surface 1, the floor mounting groove is formed by digging. (1a '').

The lower end of the structure 5 is disposed above the bottom installation groove 1a ″, and concrete is poured around the bottom installation groove 1a ″ to form a pit support bottom 20. The pit support bottom 20 forms the bottom foundation of the building. And the pit support bottom part 20 is the 1st pit support bottom part 22 which is cast in the floor installation groove 1a ", and the 2nd pit support bottom part which is poured in the outer lower part of the structure 5, and its periphery. It consists of 24.

In addition, the pit support wall portion 30 is formed to extend vertically upward from the pit support bottom portion 20 so as to surround the side circumference of the structure 5 in the longitudinal direction to support the structure 5. It is formed by.

Here, the lower end of the structure (5) is positioned so as to be spaced apart from the bottom of the bottom installation groove (1a '') by a predetermined depth (d1), the depth (d1) is the second pit support bottom portion 24 is made of concrete poured It is excavated to a depth (d2) corresponding to the thickness of the concrete is poured inside.

This is to maintain the strength of the rigid structure that can withstand the upward buoyancy applied to the bottom surface of the lower end of the structure 5 and the load transmitted from the pit support wall portion 30 at the same time, the bottom mounting groove (1a '') ) Should be formed at a depth d corresponding to the thickness of the pit support bottom 20.

Therefore, the depth d corresponding to the thickness of the second pit support bottom 24 to form the thickness of the bottom mounting groove 1a ″ to withstand both the upward buoyancy applied downward and the load transmitted upward. Because it must be excavated), the work is cumbersome and the construction cost and construction period are long.

However, when the structure of the present invention is used, the structure d while the depth d of the bottom mounting groove 1a ″ is formed to be significantly smaller than the thickness d1 of the second pit support bottom 24. 5) it is possible to form a structure of the upward buoyancy applied to the bottom of the lower end portion and the support strength to withstand the load applied from the pit support wall portion 30, thereby reducing the construction cost and construction period due to this Will have

24 is a view schematically showing the structure of the elevator pit bottom structure according to the present invention.
