Abstract

The utility model relates to an assembly type building, in particular to a fully prefabricated caisson and a connecting node thereof. The fully-prefabricated caisson comprises a caisson and a bathroom floor connected with the caisson, the caisson comprises a bottom plate and a reverse side arranged on the periphery of the bottom plate, the caisson and the bathroom floor are integrally prefabricated and formed, and the bottom plate is opposite to the bathroom floor and is arranged in a sinking mode. The bathroom floor reaches the pre-buried straight connecting reinforcement in periphery of caisson. And connecting steel bars of the fully prefabricated caisson and the cast-in-place area of the column, the wall or the beam are cast into a whole. The utility model fully prefabricates the caisson and only lowers the plates in partial areas, so that the length and the thickness of the reverse side are reduced, the space of a toilet is enlarged, the whole weight is lightened, and the on-site installation and construction cost is reduced.

Description

Full-prefabricated caisson and connecting node thereof

Technical Field

The utility model relates to an assembly type building, in particular to a fully prefabricated caisson and a connecting node thereof.

Background

In the assembled building, the bathroom adopts the same floor drainage more, because the inside pre-buried pipeline of bathroom is more, consequently the floor at sanitary room position often can fall the board (generally fall board 300 ~ 500mm) in the design, moreover because the bathroom has waterproof requirement, generally does not adopt the superimposed sheet and adopts the better prefabricated caisson of wholeness.

As shown in chinese patent CN204401783U, the conventional fully prefabricated caisson has a reverse side with a thickness of 100mm around, and the connecting steel bars bent outward are embedded in the reverse side, and during installation, the connecting steel bars bent laterally need to be anchored into the cast-in-situ layer of the wall, beam and slab, and cast-in-situ with the cast-in-situ layer of the wall, beam and slab to form a whole. Obviously, such a fully prefabricated caisson suffers from the following disadvantages:

1) the periphery of the prefabricated caisson is provided with a reverse edge with the thickness of 100mm, so that the internal space of the prefabricated caisson becomes small, and the positioning of the vertical pipe of the toilet is influenced;

2) the connecting steel bar has complex pattern, large workload of blanking and binding and increased production cost;

3) the weight of the component is large (generally more than 3 t), the type of the tower crane needs to be increased, and the construction cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that the internal space of the existing fully-prefabricated caisson is small and the connection steel bar pattern is complex, and provides the fully-prefabricated caisson and the connection node thereof, which can increase the toilet space and reduce the on-site installation and construction cost.

In order to solve the technical problem, the utility model provides a fully-prefabricated caisson which comprises the caisson and a bathroom floor slab connected with the caisson, wherein the caisson comprises a bottom plate and a reverse edge arranged on the periphery of the bottom plate, the caisson and the bathroom floor slab are integrally prefabricated and formed, and the bottom plate is arranged in a sinking way relative to the bathroom floor slab.

According to the utility model, only a local area (an area with more pipelines) of the toilet sinks (a plate falls) to form the caisson, so that the length and the thickness of the reverse side of the fully-prefabricated caisson can be reduced, the toilet space is enlarged, meanwhile, the weight of the fully-prefabricated caisson is reduced (generally 1.5-2.0 t), and the on-site installation and construction cost is reduced.

Preferably, the caisson is arranged on one side of the floor slab of the toilet, so that the caisson is suitable for the arrangement of the traditional pipeline.

Preferably, straight connecting steel bars are embedded in the peripheries of the toilet floor slab and the caisson in advance, so that the rib outlet form of the fully-prefabricated caisson is simpler, and the production labor cost is reduced.

Preferably, the thickness of the reverse side is 50 mm.

Based on the same conception, the utility model also provides a full-prefabricated caisson connecting node which comprises a full-prefabricated caisson and a column, a wall or a beam connected with the full-prefabricated caisson, wherein a cast-in-place area is arranged on the column, the wall or the beam, and connecting steel bars of the full-prefabricated caisson and the cast-in-place area of the column, the wall or the beam are cast in place into a whole.

Compared with the prior art, the utility model has the beneficial effects that:

1) the fully prefabricated caisson only has partial area plate lowering, and the length and the thickness of the reverse side become small, so that the toilet space becomes large;

2) the rib forming mode is simple, the labor cost of production is reduced, and the production cost of the component is further reduced;

3) the weight of the fully-prefabricated caisson is reduced (generally 1.5-2.0 t, and the weight is reduced by 40-50% compared with that of the traditional fully-prefabricated caisson), so that a tower crane with a smaller model can be selected, and the site installation and construction cost is reduced.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a three-dimensional structural view of a fully prefabricated caisson of the present invention.

Detailed Description

The utility model is further described below with reference to specific preferred embodiments, without thereby limiting the scope of protection of the utility model.

For convenience of description, the relative positional relationship of the components, such as: the descriptions of the upper, lower, left, right, etc. are described with reference to the layout directions of the drawings in the specification, and do not limit the structure of the present patent.

As shown in fig. 1, an embodiment of the fully prefabricated caisson of the present invention includes a caisson 1 and a bathroom floor 4 connecting the caisson 1. Caisson 1 sets up one side of bathroom floor 4, just caisson 1 is including relative bathroom floor 4 sinks the bottom plate 3 that sets up and is in bottom plate 3 reverse side 2 all around. The caisson 1 and the toilet floor slab 4 are connected through a reverse side 2, and the caisson 1 and the toilet floor slab 4 are integrally prefabricated and formed.

The toilet floor 4 and the periphery of the caisson 1 are embedded with straight connecting steel bars 5.

The thickness of the reverse side 2 is 50 mm.

When the fully prefabricated caisson is installed, the connecting steel bars 5 can be extended into the cast-in-place areas of adjacent columns, walls or beams and cast in place to form a whole.

The above description is only for the preferred embodiment of the present application and should not be taken as limiting the present application in any way, and although the present application has been disclosed in the preferred embodiment, it is not intended to limit the present application, and those skilled in the art should understand that they can make various changes and modifications within the technical scope of the present application without departing from the scope of the present application, and therefore all the changes and modifications can be made within the technical scope of the present application.
