Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a novel modular assembled concrete composite slab. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, with smooth upper and lower surfaces, facilitating finishing and making them suitable for high-rise buildings and large-span buildings requiring high overall rigidity. However, the connection between the composite slab and the cast-in-place concrete requires standardized construction techniques, and the connection between composite slabs is also relatively complex. Utility Model Content

[0003] The purpose of this utility model is to provide a novel modular assembled concrete composite slab to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel modular assembled concrete composite slab includes a composite slab body, pipeline grooves, roughened panels, embedded tie bars, transverse reinforcing bars, threaded connecting sleeves, and fixing clamps. The top of the composite slab body has equidistant transverse and longitudinal pipeline grooves. The panel outside the pipeline grooves on the top of the composite slab body is roughened using an impact drill to increase the bonding force with the top cast-in-place concrete. Embedded tie bars are installed inside the top of each roughened panel. Transverse reinforcing bars are welded to the top of each transverse embedded tie bar. The transverse reinforcing bars are connected to the transverse reinforcing bars on the top of adjacent composite slab bodies via threaded connecting sleeves. Fixing clamps are embedded on the sides of the composite slab body.

[0006] Preferably, the fixing clamps on opposite sides of the composite slab body are staggered and combined with adjacent composite slab bodies, and connected by cast-in-place concrete.

[0007] The beneficial effects of this utility model are: the utility model is reasonably designed, the pre-cut pipeline trench is used to lay water pipes and electrical conduits, ensuring the standardization and neatness of the pipelines, and the composite plate and the cast-in-place concrete are interlocked by the roughened panel and the pre-embedded tie rod, resulting in high connection strength, and the connection between the composite plates is simple and convenient.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 As shown, a novel modular assembled concrete composite slab includes a composite slab body 1, pipe grooves 2, roughened panels 3, embedded tie bars 4, transverse reinforcing bars 5, threaded connecting sleeves 6, and fixing clamps 7. The top of the composite slab body 1 has equidistant transverse and longitudinal pipe grooves 2. The panel outside the pipe grooves 2 on the top of the composite slab body 1 is roughened using an impact drill to form roughened panels 3, increasing the interlocking force with the top cast-in-place concrete. Embedded tie bars 4 are installed inside the top of each roughened panel 3. Transverse reinforcing bars 5 are welded to the top of each transverse embedded tie bar 4. The transverse reinforcing bars 5 are connected to the transverse reinforcing bars 5 on the top of adjacent composite slab bodies 1 via threaded connecting sleeves 6. Fixing clamps 7 are embedded on the sides of each composite slab body 1. The fixing clamps 7 on opposite sides of the composite slab body 1 are staggered and combined with adjacent composite slab bodies 1, connected by cast-in-place concrete.

[0012] The method of using this utility model is as follows: The composite slab body 1 is supported and installed according to the position shown in the drawing by means of a bracket. The connection between the composite slab bodies 1 is achieved by using interlaced fixing clamps 7 and subsequent cast-in-place concrete. The transverse reinforcing ribs 5 on the horizontally adjacent composite slab bodies 1 are connected to each other by threaded connecting sleeves 6. The pipeline groove 2 on the top of the composite slab body 1 can be used to pre-embed water pipes and electrical conduits. The roughened panel 3 and the pre-embedded tie rods 4 on the top can increase the interlocking force with the cast-in-place concrete.

[0013] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary in all respects, and thus equivalent variations within the scope of this invention are included within its scope.
