Referring to FIG. 2, an elevator pit supporting structure having an order function according to a preferred embodiment of the present invention includes an elevator pit 100 and an intensity reinforcing part 130.

The elevator pit 100 includes a pit support 110 and a sidewall portion 120 and may further include an auxiliary sidewall 150. The pit support 110 is formed to have an empty space therein, and the upper portion thereof is opened to form an opening 117. The feet support 110 is formed in a substantially hexahedral shape and includes a first bottom surface portion 112, a second bottom surface portion 116, and a connecting side portion 114. The first bottom surface portion 112 may be in the form of a plate having a certain thickness for securing the internal strength and the supporting strength, which is in close contact with the oyster toe portion (not shown). The second bottom surface portion 116 is spaced to an upper portion of the first bottom surface portion 112 and is formed to have a size similar to that of the first bottom surface portion 112. An opening 117 is formed at the center of the second bottom surface portion 116. The connecting side portion 114 is formed to connect the mutually opposing edges of the first bottom surface portion 112 and the second bottom surface portion 116. Further, the pit support 110 may further include a collecting unit 113. Since the pit support 110 is located in the basement of the building, it is apt to be exposed to water or moisture and is not smoothly ventilated, so that water may flow into the pit support 110. The water collecting part 113 is for collecting the water flowing into the pit supporting part 110 and is formed to be concave downward at the first bottom part 112 of the pit supporting part 110. Accordingly, the rainwater flowing into the pit support portion 110 and the washing water used for cleaning can be easily collected by the collecting unit 113, and the collected water can be easily discharged to the outside.

The side wall portion 120 is formed to protrude upwardly along the inner periphery of the opening 117 of the pit support portion 110. The side wall part 120 provides a space for the worker to work on the top of the foot support part 110. A connection part 122 is formed at the upper part of the side wall part 120 so as to be bent outwardly. Meanwhile, the size and height of the side wall 120 can be selectively formed and provided according to the situation of the field. The side wall part 120 may be integrally formed with the opening part 117 of the pit supporting part 110 or may be formed as a detachable coupling type. And a concrete layer (not shown) is formed on the outer side of the side wall part 120.

Also, at least one reinforcing frame 140 may be embedded in the strength reinforcing part 130 to maximize the strength. The reinforcement frame 140 may be formed long along the longitudinal direction, for example, a plurality of reinforcing bars formed in a U-shaped vertical section may be arranged in parallel. On the other hand, the blocking wall 113a can be mounted on the upper portion of the collecting corrugation 113 to prevent the collecting corrugation from flowing into the collecting cores 113.

The auxiliary sidewall 150 is coupled to the upper end of the sidewall portion 120 and is formed to protrude upward from the sidewall portion 120. The auxiliary sidewall 150 may be a conventional formwork, a sidewall panel, a euro foam, or may be removed after construction or permanently used as a wall in an integrated state.

Meanwhile, an order key 125 may be further provided on the outer side of the side wall part 120. The degree key 125 protrudes outwardly of the side wall part 120 and may be formed in a ring shape along the outer peripheral surface of the side wall part 120 or may be formed in only one part. The dehydration key 125 serves as an order for preventing water from seeping in or out from the gap between the side wall part 120 and the concrete layer.
