Description

Technical Field

[0001] This utility model belongs to the field of concrete floor slab technology, and specifically relates to a reinforced floor slab structure. Background Technology

[0002] A floor slab is a load-bearing structural component that divides a building vertically into several layers. It transfers the vertical loads of people and furniture, as well as the floor's own weight, to the foundation through walls, beams, or columns. Currently, most floor slabs are constructed by simply inserting reinforcing bars into the uncured concrete during the pouring of concrete beams. Reinforcing bars play a crucial role in the floor slab structure, primarily by bearing tensile stress, increasing the floor slab's load-bearing capacity and compressive strength, making the floor more robust and stable. Furthermore, reinforcing bars help improve the floor slab's durability, reducing damage caused by environmental erosion, temperature changes, and pressure variations. However, while reinforcing bars enhance the strength of concrete floor slabs, this simple manual placement method by workers, with ineffective arrangement and uneven distribution of the reinforcing bars, reduces the structural strength of the floor slab. Therefore, in the event of an earthquake, building vibration, or floor overload, the floor slab may fracture, causing personal injury and property damage. Summary of the Invention

[0003] This utility model addresses the technical problem of low floor slab structural strength caused by the ineffective arrangement of reinforcing bars during floor slab pouring in the prior art, and provides a reinforced floor slab structure.

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

[0005] A reinforced floor slab structure includes axial reinforcing ribs, transverse reinforcing ribs, and stirrup sleeves inside the floor slab. Each stirrup sleeve comprises an upper stirrup portion and a lower stirrup portion. The upper stirrup portion is semi-circular and has multiple holes for axial reinforcing ribs. The lower stirrup portion has holes for transverse reinforcing ribs. The axes of the axial reinforcing rib holes and the transverse reinforcing rib holes are perpendicular. The axial reinforcing ribs pass through the axial reinforcing rib holes of the stirrup sleeve, and the transverse reinforcing ribs pass through the transverse reinforcing rib holes of the stirrup sleeve. The axial reinforcing ribs, transverse reinforcing ribs, and stirrup sleeves can be arranged and inserted during the pouring of the floor slab.

[0006] Preferably, the floor slab also has pre-drilled holes inside, which are evenly distributed along the width of the floor slab and are circular holes penetrating both ends of the floor slab. Pre-drilled holes can reduce the weight of the floor slab and save floor slab material.

[0007] Preferably, the axial stiffeners pass through the axial stiffener holes at the top of two adjacent stiffener sleeves. The axial stiffeners string the two adjacent stiffener sleeves together, constraining the relative position between the adjacent stiffener sleeves, thereby constraining the position of the axial stiffeners.

[0008] Preferably, the upper part of the stirrup sleeve is located between adjacent precast holes. In this case, the uppermost axial stiffener is located in the middle of the floor slab, which can greatly enhance the strength of the axial stiffener in the central part of the floor slab.

[0009] Preferably, the floor slab is further provided with cross reinforcing ribs, which are located above the precast holes. The cross reinforcing ribs can enhance the load-bearing strength of the upper surface of the floor slab.

[0010] Preferably, the axial stiffeners, transverse stiffeners and cross stiffeners are all threaded steel bars.

[0011] Preferably, the number of axial reinforcing rib holes on the stirrup sleeve is 7, and the axial reinforcing rib holes are symmetrically distributed on the stirrup sleeve.

[0012] Preferably, the transverse stiffeners pass through the transverse stiffener holes of multiple stiffener sleeves simultaneously. The transverse stiffeners string the multiple stiffener sleeves together, constraining the relative positions between adjacent transverse stiffeners.

[0013] Compared with the prior art, the reinforced floor slab structure provided by this utility model has at least the following beneficial effects: the ribs in the floor slab can limit the position of the axial reinforcing bars and the transverse reinforcing bars, so that the axial reinforcing bars and the transverse reinforcing bars in the floor slab are more reasonably and evenly distributed inside the floor slab, thereby achieving the technical effect of reinforcing the floor slab; at the same time, the combination of axial reinforcing bars, transverse reinforcing bars and cross reinforcing bars can effectively enhance the load-bearing strength of the floor slab.

[0022] A reinforced floor slab structure, such as Figure 1 As shown, the floor slab has pre-drilled holes 7 evenly distributed along its width. It also includes axial reinforcing ribs 2, transverse reinforcing ribs 3, and stirrup sleeves 1, wherein the stirrup sleeve 1 has the following structure: Figure 2 As shown, it includes an upper hoop 101 and a lower hoop 102. The upper hoop 101 is semi-circular and is provided with a plurality of axial reinforcing rib holes 5. The lower hoop 102 is provided with transverse reinforcing rib holes 9. The axial reinforcing rib holes 5 are perpendicular to the axis of the transverse reinforcing rib holes 9.

[0023] like Figure 3 As shown, the axial reinforcing rib 2 passes through the axial reinforcing rib hole 5 of the stirrup sleeve 1, and the transverse reinforcing rib 3 passes through the transverse reinforcing rib hole 9 of the stirrup sleeve 1. For the sake of simplicity in the schematic diagram, Figure 3 Not all axial reinforcing bars 2 and transverse reinforcing bars 3 are shown in the diagram. When pouring the floor slab, first place two adjacent reinforcing bar sleeves 1, and then pass the axial reinforcing bar 2 through the axial reinforcing bar holes 5 on the two adjacent reinforcing bar sleeves 1. At this time, the reinforcing bar sleeves 1 can move on the axial reinforcing bars 2.

[0024] Move the stirrup sleeve 1 to the same vertical plane, and then use the transverse reinforcing rib 3 to pass through the transverse reinforcing rib hole 9 of the stirrup sleeve 1 located on the same vertical plane.

[0025] The precast hole 7 is a circular hole that passes through both ends of the floor slab. The precast hole 7 can be made by placing a cylindrical mold during concrete pouring and removing it after the concrete has solidified.

[0026] like Figure 4 As shown, the upper part of the stirrup sleeve 1 is located between adjacent precast holes 7, and the axial reinforcing ribs 2 passing through the upper part of the stirrup sleeve 1 play a role in connecting and supporting the floor slab structure between adjacent precast holes 7.

[0027] like Figure 1 As shown, the floor slab is also provided with cross reinforcing ribs 8, which are located above the precast holes 7. The cross reinforcing ribs 8 can be placed directly on the concrete surface during concrete pouring and manually pressed into the concrete.

[0028] The axial reinforcing ribs 2, transverse reinforcing ribs 3, and cross reinforcing ribs 8 can all be made of threaded steel. The number of axial reinforcing rib holes 5 on the hoop sleeve 1 is 7, and the axial reinforcing rib holes 5 are symmetrically distributed on the hoop sleeve 1.
