Abstract
The utility model discloses a prestressed concrete combined composite floor slab, which comprises a first prefabricated floor slab body and a second prefabricated floor slab body which are adjacently spliced, wherein a concrete layer is poured above the spliced first floor slab body and the spliced second floor slab body, the splicing ends of the first prefabricated floor slab body and the second prefabricated floor slab body are in a ladder shape, a plurality of convex blocks are arranged above the splicing surface of the second prefabricated floor slab body, a plurality of grooves for the convex blocks to be inserted are arranged above the splicing surface of the first prefabricated floor slab body, the lengths of the convex blocks are both larger than the depth of the grooves, the splicing positions of the first prefabricated floor slab and the second floor slab are filled with concrete, the smoothness of connection between the prefabricated floor slabs is increased through the ladder-shaped connection structure, the convex blocks are inserted into the grooves to prevent the splicing positions of the prefabricated floor slabs from being connected and dislocated to leave gaps after the splicing, the connection strength is increased through the filling of the concrete in the gaps, the connection strength is further increased by the connection plate.
Description
Technical Field
The utility model relates to a housing construction technical field, specific theory relates to a combined coincide floor of prestressed concrete.
Background
With the continuous development of the construction industry in China, the building industrialization becomes the development direction of buildings in the future. The prefabricated composite floor slab of assembled of making in mill can reduce the loaded down with trivial details process of formwork, form removal, shorten advantages such as construction cycle as the novel product of floor, the roof of replacing cast-in-place high-rise building, roof, and current composite floor slab, the back connecting portion fragile after the assembly, and current composite floor slab connectivity is poor.
SUMMERY OF THE UTILITY MODEL
For overcoming foretell not enough, the utility model provides a combined coincide floor of prestressed concrete, first precast floor body and second precast floor body including adjacent concatenation, concrete layer has been pour to first floor body and second floor body top of concatenation, the concatenation end of first precast floor body and second precast floor body all is the echelonment, the concatenation face top of second precast floor body is provided with a plurality of lugs, the concatenation face top of first precast floor body is provided with a plurality of lug male recesses that supply, and the length of a plurality of lugs all is greater than the degree of depth of recess, first precast floor and second floor concatenation department fill have the concrete.
Preferably, the upper surface and the lower surface of the splicing part of the first prefabricated floor slab body and the second prefabricated floor slab body are provided with notches, the first prefabricated floor slab body and the second prefabricated floor slab body are connected through the connecting plates arranged in the notches, the connecting plates are fixed in the notches through screws, inverted V-shaped hoisting reinforcing steel bars are further arranged on the two floor slab bodies, hoisting is convenient, and concrete layers are poured after the hoisting splicing is completed.
The utility model has the advantages that: the connection smoothness between the prefabricated floor slabs is improved through the stepped connection structure, the connection dislocation of the prefabricated floor slabs is prevented by inserting the convex blocks into the grooves, the length of the convex blocks is larger than the depth of the grooves, gaps are reserved at the splicing positions after the prefabricated floor slabs are spliced, the connection strength is improved by filling concrete in the gaps, and the connection strength is further improved through the connecting plates.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The figures are simplified schematic diagrams illustrating the basic structure of the invention in a schematic way only, and therefore they show only the components relevant to the invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, the two components can be communicated with each other inside, the fixed connection can be welding, gluing and the like, and for those skilled in the art, the specific meaning of the terms in the present invention can be understood according to specific situations.
As shown in fig. 1, a prestressed concrete combined composite floor slab comprises a first prefabricated floor slab body 1 and a second prefabricated floor slab body 2 which are adjacently spliced, a concrete layer 3 is poured above the first prefabricated floor slab body 1 and the second prefabricated floor slab body 2 which are spliced, the splicing ends of the first prefabricated floor slab body 1 and the second prefabricated floor slab body 2 are in a ladder shape, a plurality of convex blocks 4 are arranged above the splicing surface of the second prefabricated floor slab body 1, a plurality of grooves for the convex blocks 4 to insert are arranged above the splicing surface of the first prefabricated floor slab body 1, the lengths of the convex blocks 4 are larger than the depth of the grooves, concrete is filled at the splicing position of the first prefabricated floor slab and the second floor slab, and a gap is left at the splicing position of the two prefabricated floor slabs due to the fact that the length of the convex blocks is larger than the depth of the grooves, and the concrete is filled into the gap.
The upper surface and the lower surface of the splicing part of the first prefabricated floor slab body 1 and the second prefabricated floor slab body 2 are provided with notches, the notches of the upper surface and the lower surface of the two spliced floor slab bodies form a square groove after splicing, the first prefabricated floor slab body 1 and the second prefabricated floor slab body 2 are connected by arranging the connecting plate 5 in the notch, the connecting plate is arranged in the square groove formed by splicing the two floor slab bodies, the connecting plate 5 is fixed in the notches through the screws 6, inverted V-shaped hoisting reinforcing steel bars are further arranged on the two floor slab bodies, hoisting is convenient, and a concrete layer is poured after the hoisting splicing is finished.
In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
