Abstract
The utility model discloses a prefabricated superimposed sheet of leak protection thick liquid, including square superimposed sheet body, this internal reinforcing bar that is equipped with at horizontal direction vertically and horizontally staggered of superimposed sheet, the reinforcing bar outwards extends along the terminal surface of superimposed sheet body, and superimposed sheet body top surface is equipped with the connecting reinforcement of the font of falling V, and the top surface of the outstanding superimposed sheet body in sharp portion of connecting reinforcement, the reinforcing bar that is close to superimposed sheet body concatenation end is outwards extended to the top surface direction of following superimposed sheet body and is buckled. The prefabricated composite slab for preventing the leakage of the slurry is not easy to leak the slurry when a reinforced concrete layer is cast in place.
Description
The technical field is as follows:
the utility model relates to a building field specifically says a prefabricated superimposed sheet of leak protection thick liquid.
Background art:
the laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The composite floor slab has good integrity, the upper and lower surfaces of the slab are smooth, the decoration of a finish coat is convenient, and the composite floor slab is suitable for high-rise buildings and large-bay buildings with higher requirement on the integral rigidity. The prestressed main reinforcement of the thin plate is the main reinforcement of the laminated floor slab, and the upper concrete cast-in-place layer is only provided with negative moment reinforcement and constructional reinforcement. The prestressed thin plate is used as a bottom die of a cast-in-place concrete layer, and a template does not need to be supported by the cast-in-place layer. The bottom surface of the thin plate is smooth and flat, and after plate seams are processed, the ceiling can not be plastered any more. The composite floor slab has the advantages of integrity, high rigidity, good crack resistance, no increase of reinforcing steel bar consumption, template saving and the like of a cast-in-place floor slab. The laminated slab is widely applied to the construction process, the construction period is greatly shortened due to the characteristic of convenient installation, various laminated slab forms exist in the technology applied on site, and the splicing technology among the laminated slabs usually adopts the form that a reinforcing steel bar protruding from one side of the laminated slab is inserted into a reinforcing steel bar inserting hole on one side of another laminated slab to form a reinforcing steel bar connecting mode. However, in any structure, when the concrete is superposed with cast-in-place concrete after splicing, slurry is easy to leak at the splicing part.
The utility model has the following contents:
the utility model aims to solve the technical problem that a prefabricated superimposed sheet of the leak protection thick liquid that is difficult for leaking thick liquid when cast-in-place reinforced concrete layer is provided.
The technical solution of the utility model is, a prefabricated superimposed sheet of leak protection thick liquid is provided, including square superimposed sheet body, this internal reinforcing bar that is equipped with at horizontal direction vertically and horizontally staggered of superimposed sheet, the reinforcing bar outwards extends along the terminal surface of superimposed sheet body, and superimposed sheet body top surface is equipped with the connecting reinforcement of the font of falling V, and the top surface of the outstanding superimposed sheet body in sharp portion of connecting reinforcement is buckled to the top surface direction of the superimposed sheet body after the reinforcing bar that is close to superimposed sheet body concatenation end outwards extends, and superimposed sheet body concatenation end bottom surface has to the recess of dodging that the top surface direction is sunken, dodges the recess and extends towards superimposed sheet body direction by the terminal surface of concatenation end.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: after the laminated slab body is spliced, the elastic anti-seepage pad is arranged in the avoidance groove below the corresponding splicing position, and then the template below the laminated slab body is used for supporting, so that mortar leakage at the splicing position cannot be caused when concrete is poured.
Preferably, the avoiding groove is formed along the length direction of the splicing end of the laminated slab body.
Furthermore, the width of the avoiding groove is 6-10cm, and the depth of the avoiding groove is 0.5-0.8 cm.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the utility model discloses the concatenation cooperation sketch map.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1 and 2, a prefabricated superimposed sheet of leak protection thick liquid, including square superimposed sheet body 1, be equipped with reinforcing bar 2 at the crisscross of horizontal direction in superimposed sheet body 1, reinforcing bar 2 outwards extends along the terminal surface of superimposed sheet body, and 1 top surface of superimposed sheet body is equipped with the connecting reinforcement 3 of the font of falling V, and the top surface of the outstanding superimposed sheet body in point portion of connecting reinforcement 3, the reinforcing bar that is close to superimposed sheet body concatenation end outwards extends to the top surface direction of following superimposed sheet body and buckles, and it is hook-like to buckle into the circular arc in this embodiment, and superimposed sheet body concatenation end bottom surface has the recess 4 of dodging towards the top surface direction is sunken, dodges recess 4 and extends towards superimposed sheet body direction by the terminal surface of concatenation end, dodges recess 4 and is the plane groove. Of course, correspondingly, the corresponding end face of the laminated slab body is also provided with a jack which is in splicing fit with the steel bar.
The utility model discloses a set up at concatenation end bottom surface and dodge the recess, can set up elasticity anti-seepage pad in the recess through dodging at double-phase adjacent superimposed sheet plate body when the construction, this elasticity anti-seepage pad can select sheets such as PVC or PP, with its laminating in dodging the recess, then the beneath template supporting that supports the superimposed sheet that is used for elasticity anti-seepage pad holding is in the accommodation space of dodging the recess formation of two superimposed sheets, like this, when pouring the construction, the mortar is difficult for locating the seepage from this concatenation. And after the concrete is cured, when the template is dismantled, the elastic anti-seepage pad is taken down along the belt. In order to achieve better seepage-proofing effect, one surface of the elastic seepage-proofing pad, which is in contact with the inner wall of the avoiding groove, can be coated with pressure-sensitive adhesive or other adhesives easy to clean, so that the elastic seepage-proofing pad can be conveniently fixed on the laminated slab.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
