Description

Strength Reinforced Sump and Sump Installation Method {Sump Pit}

The present invention relates to a water collecting well made of a metal material, and more particularly, the strength reinforcing part for strength reinforcement is formed on the side wall of the water collecting part, thereby enabling mass production, and easily reinforcing the rigidity and supporting strength of the water collecting well. It is about the sump structure which can be done. In addition, the present invention relates to a method of installing a sump well in which the sump is installed in the concrete layer, utilizing the concrete layer to increase the internal strength as well as the fixing force.

In general, the integrated sump of the metal material installed in the basement of the building has a very high thickness of the sump in order to support strong up buoyancy and bearing strength by the groundwater, or by installing a reinforcing rib on the outside or the inside to weld the stiffness of the sump. Reinforce.

In order to reinforce the rigidity of the sump well, a rib is welded integrally in the sump and a flange is integrally welded outward. A rib is welded and coupled to the collection part by interconnecting the bottom and the side wall to the inside, and a flange in the form of a plate is welded to the outside of the collection part along the outer circumferential surface thereof.

These ribs and flanges allow the collector to have structural rigidity and support strength while minimizing the thickness of the sidewalls and bottom of the collector. However, since the conventional ribs and flanges are welded to the side walls and the bottom of the water collecting portion in such a manner that the sharp ends are simply protruded to form the ribs and the flanges, the internal work is inconvenient and the appearance is not good. In addition, since the parts integrated on the side walls and the floor are limited, the strength reinforcing effect also remains a certain level.

In addition, the water collecting well of the steel structure having a large number of ribs has a disadvantage that the size of the ribs is increased by combining a plurality of ribs of vertical plate type in order to reinforce the strength and secure the own weight, and the weight of the structure is increased, making it difficult to manufacture and transport. . However, in the case of forming the concrete structure through the formwork, there is a problem that the cost is high due to the difficult reinforced concrete work, the construction period is increased. Therefore, in the case of the steel collection basin, the necessity of the installation method to replace the reinforcing bar connection of the complex structure is required according to the weakness of the upper pressure due to the small load.

The strength reinforcing portion 24 is a shape having a surface in which the side wall 22 is bent several times along the vertical direction inward or outward, and the strength reinforcing portion 24 is actually formed by bending a flat plate or a long shape. It is also possible to form a plate by welding mutually.

When the cross section of the strength reinforcing portion 24 is enlarged, as shown in the circle, the space protruding while the reinforcing surface 24a and the reinforcing surface 24b meet in an outwardly facing shape in a shape that is bent from the side wall 22. To form. The cross-sectional shape of the strength reinforcing portion 24, in addition to the V-shaped, by changing the number or shape of the reinforcing surface, can be variously envisaged in the c-shaped, U-shaped, polygonal, etc., it is sufficient to have the appearance of the bent shape in the vertical direction.

The side wall portion 20 is a vertically formed wall surface, and has a side wall 22 and a coupling portion 26 extending horizontally to an upper end thereof. The coupling part 26 forms a coupling hole 28 so that an additional side wall (or flow form, formwork, and the like; B, FIG. 5) can be coupled to the upper side of the side wall part 20, such as bolts, nuts, and keys. It is preferable to combine with a coupling member. In addition, the outer side of the coupling portion 26 to form a reinforcing bar coupling hole 27, the reinforcing bar coupling hole 27 is preferably inserted into the reinforcing bar arranged in the concrete layer to be mutually coupled, support.

The side wall B may be fixedly coupled to the coupling part 26 provided at the upper side of the side wall 22 of the side wall part 20 by the coupling member. The side wall (B) can use a conventional formwork, a panel for side walls, a flow path, or the like, and may be removed after construction or permanently used as a wall in an integrated state.

After the casting of the discarded concrete, the bottom concrete is poured out of the form B to form the bottom concrete layer 2, at which time, through the opening of the inner accommodating space 10, to a predetermined height therein. By pouring concrete, it can be hardened in the inner receiving space 10.

That is, the inside of the inner receiving space 10 may be filled together at the time of floor concrete pouring, so that the own weight concrete is cured in the state where the inner receiving space 10 has its own weight. Through this, the inner accommodating space portion 10 and the side wall portion 20, which are simply made of metal, compensate for the disadvantage of having a relatively low load and strength, so as to supplement the post load to have a high load and strength. do. In some cases, when the discarded concrete layer 1 is formed, the discarded concrete may be poured into the inner accommodating space 10 to form the self-weighted concrete. This process can be equally applied to the sump consisting of only the side wall and the bottom without the inner accommodating space 10.

Referring to FIG. 6, the discarded concrete layer 1 may be formed first, and the inner accommodating space 10 may be disposed thereon. In this case, the self-weight concrete can be filled together (before, simultaneously or after) when placing concrete.

At this time, the discarded concrete layer is formed to a position higher than the load supporting portion of the sump, and serves to fix the sump. In addition, when placing the bottom concrete to the top of the discarded concrete layer, by pouring concrete to a certain height into the interior of the sump, the self-weight concrete layer is cured in the sump.

On the other hand, the water collecting well should be installed before casting concrete, but in some cases, after pouring concrete, the water collecting well may be installed on the upper side. In this case, it is possible to press the load supporting part of the water collecting well through the floor concrete. have.

The self-weighted concrete layer formed inside the sump is formed by pouring a certain amount of concrete into the inner accommodating space part when placing the bottom concrete, but in some cases, may be formed when casting the discarded concrete.

In addition, instead of introducing concrete into the inner accommodating space portion, it is possible to form a spaced apart support portion at the bottom of the sump, and to harden together through the discarded concrete or the bottom concrete that flows into the lower portion and hardens, thereby enabling load support. . Even in this case, the concrete may be introduced into the inner accommodating space, and as described above, the concrete may be introduced at the time of cast concrete or floor concrete.

In addition, as the lower space formed by the spaced apart support part, the discarded concrete may be introduced or the bottom concrete may also be integrally and hardened while the bottom concrete is also introduced. In the case where the spaced support part is disposed on the discarded concrete layer, the bottom concrete is integrally introduced with the bottom concrete. , Can be cured.
