Description

Technical Field

[0001] This utility model relates to a composite slab, specifically a novel prefabricated composite slab structure. Background Technology

[0002] Precast composite slabs are a type of floor slab system that combines a precast concrete base slab with a cast-in-place concrete composite layer. This system combines the high efficiency of precast concrete with the flexibility of cast-in-place construction, increasing construction speed, reducing on-site work, and contributing to improved overall building quality.

[0003] Existing precast composite slabs only have one layer of internal steel reinforcement, usually located in the center of the composite layer. This means that the steel reinforcement layer can only reinforce the center of the composite layer, without considering the reinforcement of the top and bottom of the composite layer. As a result, the overall stability is poor, and deformation and damage are likely to occur during transportation, construction and use. Utility Model Content

[0004] The purpose of this utility model is to provide a novel precast composite slab structure, which is made of an upper steel bar assembly and a lower steel bar assembly that are combined with each other, and the upper steel bar assembly and the lower steel bar assembly have different heights. The combination of the two improves the overall stability, making it less prone to deformation or damage during transportation, construction and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel precast composite slab structure includes a concrete base slab and a composite layer disposed on the concrete base slab. An upper reinforcing bar assembly and a lower reinforcing bar assembly are disposed within the composite layer. The upper reinforcing bar assembly includes multiple first upper reinforcing bars and multiple second upper reinforcing bars, which are arranged intersectingly. Adjacent first and second upper reinforcing bars are connected by upper connecting bars. Multiple upper connecting bars are provided, and each upper connecting bar has a fastening seat fixed to its bottom. The lower reinforcing bar assembly includes multiple lower reinforcing bars arranged in a straight line, which are connected by lower connecting bars. Multiple lower connecting bars are provided, and multiple fastening seats are respectively fixed to the multiple lower reinforcing bars. The first upper reinforcing bars, second upper reinforcing bars, upper connecting bars, fastening seats, lower reinforcing bars, and lower connecting bars are all precast within the composite layer.

[0006] Preferably, the height values ​​of the multiple first upper reinforcing bars are equal, the height values ​​of the multiple second upper reinforcing bars are equal, and the height value of the first upper reinforcing bars is greater than the height value of the second upper reinforcing bars; setting the multiple first upper reinforcing bars and the multiple second upper reinforcing bars to different height values ​​is to enable the reinforcement effect of the upper reinforcing bar assembly to cover a deeper thickness within the composite layer.

[0007] Preferably, upper collars are fixed to the outside of multiple first upper reinforcing bars and multiple second upper reinforcing bars, and multiple upper collars are connected to upper connecting bars.

[0008] Preferably, all the upper connecting ribs are inclined and distributed at equal intervals.

[0009] Preferably, multiple protrusions are fixed on the upper and lower ends of each lower connecting rib, and the multiple protrusions are distributed in a straight line.

[0010] Preferably, multiple lower sleeves are fixed to the outside of the multiple lower reinforcing bars, and the multiple lower sleeves are connected to the lower connecting bars.

[0011] Preferably, multiple extended steel bar seats are fixed on the top of the composite layer, and the multiple extended steel bar seats are distributed at equal intervals on the composite layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model divides the steel reinforcement layer into an upper steel reinforcement assembly and a lower steel reinforcement assembly. In the upper steel reinforcement assembly, the first upper steel reinforcement and the second upper steel reinforcement have different heights and are designed to cross each other. In addition, the upper steel reinforcement assembly and the lower steel reinforcement assembly have different heights. The upper steel reinforcement assembly and the lower steel reinforcement assembly are combined into one unit, which can achieve a fastening effect at different depths inside the composite layer. The combination of the two also improves the overall stability. Therefore, it can significantly improve the stability of the new precast composite slab structure, making it less prone to deformation or damage during transportation, construction and use.

[0023] Please see Figures 1 to 2The present invention provides an embodiment of a novel precast composite slab structure, comprising a concrete base slab 1 and a composite layer 2 disposed on the concrete base slab 1. An upper reinforcing bar assembly 3 and a lower reinforcing bar assembly 4 are disposed inside the composite layer 2. A plurality of extended reinforcing bar seats 5 are fixed on the top of the composite layer 2, and the plurality of extended reinforcing bar seats 5 are distributed at equal intervals on the composite layer 2.

[0024] Please see Figure 3 The upper reinforcing bar assembly 3 includes multiple first upper reinforcing bars 31 with equal height values, and the lower reinforcing bar assembly 4 includes multiple lower reinforcing bars 41 arranged in a straight line.

[0025] Please see Figure 4 The upper reinforcing bar assembly 3 also includes multiple second upper reinforcing bars 32, all of which have the same height. The height of the first upper reinforcing bar 31 is greater than that of the second upper reinforcing bars 32. Setting the multiple first upper reinforcing bars 31 and the multiple second upper reinforcing bars 32 to different heights allows the upper reinforcing bar assembly 3 to provide reinforcement covering a deeper thickness within the composite layer 2. Furthermore, the first upper reinforcing bars 31 and the second upper reinforcing bars 32 are intersecting, and adjacent first upper reinforcing bars 31 and second upper reinforcing bars 32 are connected by upper connecting bars 33. Multiple upper connecting bars 33 are provided, and fastening seats 34 are fixed at the bottom of each upper connecting bar 33. The multiple upper connecting bars 33 are inclined and evenly distributed. The inclination angle of the upper connecting bars 33 is between 8° and 25°. The arrangement of multiple upper connecting bars 33 and multiple fastening seats 34 allows the reinforcement effect of the upper steel bar assembly 3 to cover all parts of the surface of the composite layer 2. Upper collars 35 are fixed on the outside of multiple first upper steel bars 31 and multiple second upper steel bars 32. The multiple upper collars 35 are connected to the upper connecting bars 33.

[0026] Adjacent lower reinforcing bars 41 are connected by lower connecting bars 42. Multiple lower connecting bars 42 are provided, and multiple fastening seats 34 are respectively fixed to multiple lower reinforcing bars 41. Multiple protrusions 43 are fixed on the upper and lower ends of each lower connecting bar 42, and these protrusions 43 are arranged in a straight line. The multiple protrusions 43 can reinforce the structure of the lower connecting bars 42, making them less prone to deformation or bending, thus ensuring the reinforcement effect of the lower connecting bars 42 on the lower reinforcing bars 41. Multiple lower sleeves are fixed on the outer sides of each lower reinforcing bar 41. Ring 44, multiple lower rings 44 are all connected to lower connecting bars 42, the number of lower rings 44 is equal to the number of fastening seats 34. In addition, the first upper bar 31, the second upper bar 32, the upper connecting bar 33, the fastening seat 34, the lower bar 41 and the lower connecting bar 42 are all prefabricated inside the composite layer 2. The upper bar assembly 3 is located above the lower bar assembly 4. The two are combined with each other, thereby reinforcing the composite layer 2 at different thicknesses, significantly improving the stability of the composite layer 2, and making the composite layer 2 less prone to deformation or damage during transportation, construction and use.

[0027] Please see Figure 5 Multiple first upper reinforcing bars 31 and multiple second upper reinforcing bars 32 extend from one side of the composite layer 2, and multiple lower reinforcing bars 41 extend from the other side of the composite layer 2.
