Technical Field

The utility model relates to a water collecting device for a bottom plate of a building basement, and belongs to the technical field of construction of the building basement.

Background

When the basement is transformed, a water collecting pit is often required to be added on the bottom plate of the basement. In the prior art, a concrete pouring water collecting pit is adopted after a basement bottom plate is chiseled. In the prior art, a template needs to be erected, sump concrete is poured, after the sump concrete is completely solidified and reaches a maintenance period, the template and a template supporting member need to be dismantled, the construction process is complex, and the construction period is long. And because concrete placement sump pit lateral wall thickness is great, the area that basement bottom plate chiseled is also corresponding great. Thus, the prior art still has deficiencies and needs to be further improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a water collecting device for a bottom plate of a basement of a building, which is used for shortening the construction period and overcoming the defects in the prior art.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model relates to a water collecting device for a basement bottom plate of a building, which comprises a basement bottom plate; a hole is formed in the basement bottom plate, and a foundation pit is formed in the foundation at the bottom of the hole; a steel water collecting tank is arranged in the foundation pit, and a group of angle steel stiffening rings are sleeved at the upper part of the steel water collecting tank; the periphery of the angle steel stiffening ring is connected with embedded steel bars in the basement bottom plate.

In the building basement bottom plate water collecting device, the foundation pit is a cone cavity with a large upper part and a small lower part.

In the building basement bottom plate water collecting device, a bottom plate cushion layer is arranged between the top surface of the foundation pit and the bottom surface of the basement bottom plate.

In the building basement bottom plate water collecting device, a concrete cushion and a non-shrinkage grouting material are sequentially paved between the foundation pit and the steel water collecting tank.

In the aforementioned building basement bottom plate water-collecting device, the angle steel stiffening ring has been pour around and has not had shrink pea gravel concreten with the pre-buried reinforcing bar junction between the basement bottom plate.

Due to the adoption of the technical scheme, compared with the prior art, the utility model adopts the steel plate to manufacture the water collecting tank, and the construction time is obviously shortened compared with a concrete-poured water collecting pit. The steel water catch bowl can obviously reduce wallboard thickness, and basement bottom plate chiseling work load reduces. The steel water collecting tank is installed in place and can replace the template after the steel bars of the basement bottom plate are firmly connected, so that the workload and time for erecting and dismantling the template are saved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The utility model relates to a water collecting device for a basement bottom plate of a building, which comprises a basement bottom plate 3 as shown in figures 1 and 2; a hole 4 is arranged on the basement bottom plate 3, and a foundation pit 10 is arranged on a foundation 11 at the bottom of the hole 4; a steel water collecting tank 1 is arranged in the foundation pit 10, and a group of angle steel stiffening rings 2 are sleeved on the upper part of the steel water collecting tank 1; the periphery of the angle steel stiffening ring 2 is connected with the embedded steel bars 6 in the basement bottom plate 3. The foundation pit 10 is a conical cavity with a large upper part and a small lower part. A bottom plate cushion layer 5 is arranged between the top surface of the foundation pit 10 and the bottom surface of the basement bottom plate 3. And a concrete cushion 7 and a non-shrinkage grouting material 8 are sequentially paved between the foundation pit 10 and the steel water collecting tank 1. And the joints of the embedded steel bars 6 between the periphery of the angle steel stiffening ring 2 and the basement bottom plate 3 are poured with shrinkage-free fine stone concrete 9.

In the specific implementation, the construction is carried out according to the following steps:

step 1, according to the specific size of a steel water collecting tank 1 which is increased as required, the water collecting tank with the corresponding size is manufactured by adopting a steel plate, and an angle steel stiffening ring 2 is welded on the outer wall of the upper part of the water collecting tank. The position of the angle steel stiffening ring 2 is convenient to be connected with the embedded steel bars 6 in the basement bottom plate when the water collecting tank is installed.

And 2, paying off the basement bottom plate 3 according to the size and the position of the steel water collecting tank 1, and considering factors such as the depth of the steel water collecting tank, the slope of the concrete cushion 7, the reserved construction operation space and the like when determining the chiseling-off range line of the basement bottom plate.

And 3, chiseling holes on the basement bottom plate after checking that the chiseling range line of the basement bottom plate is not wrong. And cutting off the embedded steel bars 6 in the basement bottom plate 3 when the hole is chiseled.

And 4, digging a foundation pit 10 on the foundation 11 below the basement bottom plate.

And 5, pouring a concrete cushion 7 and maintaining. The concrete cushion 7 can adopt the same concrete strength grade as the bottom plate cushion 5 under the bottom plate of the basement.

And 6, when the concrete cushion layer 7 reaches the set concrete strength, the steel water collecting tank 1 can be installed. During installation, after the steel water collecting tank 1 is in place, the bottom plate reinforcing steel bars 6 are welded with the angle steel stiffening ring 2.

And 7, pouring a non-shrinkage grouting material 8 between the outer wall of the part, below the basement bottom plate 3, of the steel water collecting tank 1 and the inner wall of the concrete cushion 7, wherein the concrete strength grade of the non-shrinkage grouting material 8 is not lower than that of the basement bottom plate 3.

And 8, filling non-shrinkage fine stone concrete 9 between the outer wall of the upper part of the steel water collecting tank 1 and the basement bottom plate 3 at the pit edge of the foundation pit 10, and vibrating to be compact. The concrete strength grade of the non-shrinkage fine-stone concrete 9 is higher than that of the basement bottom plate 3 by one grade.

And 9, after the concrete strength of the non-shrinkage fine aggregate concrete 9 reaches the set requirement, constructing the upper building surface.

Compared with a water collecting pit poured by concrete, the water collecting tank manufactured by the steel plate has the advantage that the construction time is obviously shortened. The steel water catch bowl can obviously reduce wallboard thickness, and basement bottom plate chiseling work load reduces. The steel water collecting tank is installed in place and can replace the template after the steel bars of the basement bottom plate are firmly connected, so that the workload and time for erecting and dismantling the template are saved.
