Abstract
Description
Technical Field
[0001] This application relates to the field of prefabricated building technology, and in particular to a foldable prefabricated building floor slab component that is easy to transport. Background Technology
[0002] In the field of modern prefabricated buildings, precast concrete composite slabs, as the core component of floor slabs, are widely used in various building projects due to their advantages such as high industrial production efficiency, short construction cycle, and stable structural performance.
[0003] Traditional precast concrete composite slabs are typically monolithic structures, large in size and heavy in weight. During transportation, the pre-installed reinforcing steel structure inside and on the surface of the slab significantly affects the stability of the components. Because the reinforcing steel often protrudes from the slab surface or forms irregular structures at the edges, when multiple composite slabs are stacked, the reinforcing steel can easily come into contact with each other, preventing the slabs from fitting tightly together. This shifts the center of gravity of the stack, increasing the risk of swaying, tilting, or even tipping over during transport. Furthermore, the protruding reinforcing steel can collide and rub against other components, causing bending and damage to both the reinforcing steel structure and the slab itself, which is detrimental to subsequent use.
[0004] Based on the above reasons, this utility model proposes a foldable prefabricated building floor slab component that is easy to transport, which can meet transportation needs, improve placement stability, reduce component damage, and enhance transportation convenience. Utility Model Content
[0005] In view of the above problems, this application provides a foldable prefabricated building floor slab component that is easy to transport, so as to solve the problems of inconvenient transportation and easy damage of prefabricated building floor slab components in the prior art.
[0006] This application provides a foldable prefabricated building floor slab component that is easy to transport, including a central concrete slab, with side concrete slabs on both sides of the central concrete slab. Both the central and side concrete slabs are reinforced with steel bars, and each contains several longitudinal steel bars. Both the central and side concrete slabs have several concentrically arranged mounting holes, into which transverse steel bars are inserted. The central and side concrete slabs are inclined to one side of each other, and a movable connecting assembly is provided between them. A fixing block is fixedly connected to the top surface of each of the two side concrete slabs.
[0007] In some embodiments, the movable connection assembly includes two connecting plates, which are movably connected to each other. Each of the two connecting plates is movably connected to a fixing rod on a side away from each other, and the fixing rods are respectively cast into the central concrete slab and the side concrete slab.
[0008] In some embodiments, the reinforcing steel structure includes bent reinforcing bars, two of which are corrugated and symmetrically arranged, and three fixed reinforcing bars are fixedly connected between the two bent reinforcing bars. The two lower fixed reinforcing bars and the lower part of the bent reinforcing bars are respectively cast inside the central concrete slab and the side concrete slab.
[0009] In some embodiments, the fixing blocks on the two side concrete slabs are positioned to match each other, and the top surface of the fixing blocks is positioned higher than the uppermost side section height of the bent reinforcing bar.
[0010] In some embodiments, the mounting holes on the central concrete slab are flared on both sides, and the mounting holes on the side concrete slabs are flared on the side facing the central concrete slab.
[0011] In some embodiments, the transverse and longitudinal reinforcing bars are arranged perpendicularly and staggered, with the transverse reinforcing bars positioned above the longitudinal reinforcing bars.
[0012] In some embodiments, the central concrete slab is inclined at 45 degrees on both sides, and the two side concrete slabs are inclined at 45 degrees on the side closest to the central concrete slab.
[0013] The above scheme allows for the folding of the floor slab during transportation by manipulating one side of the concrete slab, causing both the central and side concrete slabs to fold into a concave shape. Simultaneously, the fixing blocks on the two side concrete slabs are stacked together, thus achieving the folding function of the floor slab component. Stacking the central and side concrete slabs on their flat surfaces effectively improves the stability of the floor slab component during transportation. Furthermore, after folding, the reinforcing steel structure is positioned between the central and side concrete slabs, reducing damage caused by protruding reinforcing steel structures and minimizing damage to the floor slab component.

[0028] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0029] like Figure 1-5 As shown, this application embodiment provides a foldable prefabricated building floor slab component that is easy to transport, including a central concrete slab 1, with side concrete slabs 2 on both sides of the central concrete slab 1. Both the central concrete slab 1 and the side concrete slabs 2 are provided with a steel reinforcement structure 3. The steel reinforcement structure 3 includes bent steel bars 11, which are corrugated and symmetrically arranged in two. Three fixed steel bars 12 are fixedly connected between the two bent steel bars 11. The lower part of the two fixed steel bars 12 and the lower part of the bent steel bars 11 are respectively cast inside the central concrete slab 1 and the side concrete slabs 2. The steel reinforcement structure 3 facilitates its use during subsequent pouring.
[0030] Furthermore, both the central concrete slab 1 and the side concrete slab 2 are filled with several longitudinal steel bars 4. Both the central concrete slab 1 and the side concrete slab 2 are provided with several concentric installation holes 5. Transverse steel bars 6 are inserted into the installation holes 5. The transverse steel bars 6 and the longitudinal steel bars 4 are arranged perpendicularly and staggered, and the transverse steel bars 6 are located on the upper side of the longitudinal steel bars 4.
[0031] In the technical solution of this embodiment, the setting of longitudinal steel bars 4 can effectively increase the structural strength of the central concrete slab 1 and the side concrete slab 2. By inserting transverse steel bars 6 through the installation hole 5, on the one hand, the positioning and docking between the central concrete slab 1 and the side concrete slab 2 can be realized, which facilitates the construction and use of the floor slab components. On the other hand, it can effectively increase the strength of the central concrete slab 1 and the side concrete slab 2, resulting in good performance.
[0032] The mounting holes 5 on the central concrete slab 1 are flared on both sides, and the mounting holes 5 on the side concrete slab 2 are flared on the side facing the central concrete slab 1. During pouring, the stability of the connection between the transverse steel bar 6 and the central concrete slab 1 and the side concrete slab 2 is improved, thereby increasing the strength of the floor slab components. At the same time, it also facilitates the insertion of the transverse steel bar 6.
[0033] The central concrete slab 1 is inclined at 45 degrees on both sides, and the two side concrete slabs 2 are also inclined at 45 degrees on the side closest to the central concrete slab 1. A movable connecting component 7 is provided between the central concrete slab 1 and the side concrete slabs 2. The movable connecting component 7 includes a connecting plate 9. There are two connecting plates 9, and the two connecting plates 9 are movably connected. A fixing rod 10 is movably connected to the side of the two connecting plates 9 that is far away from each other. The fixing rod 10 is cast in the central concrete slab 1 and the side concrete slabs 2 respectively. A fixing block 8 is fixedly connected to the top surface of the two side concrete slabs 2. The fixing blocks 8 on the two side concrete slabs 2 are positioned to match each other. The height of the top surface of the fixing block 8 exceeds the height of the uppermost side section of the bent steel bar 11.
[0034] In the technical solution of this embodiment, during transportation, by operating one side of the concrete slab 2, the central concrete slab 1 and the side concrete slab 2 are folded into a concave shape. At the same time, the fixing blocks 8 on the two side concrete slabs 2 are stacked together, which realizes the folding function of the floor slab component. At this time, by stacking the central concrete slab 1 and the side concrete slab 2 on their flat surfaces, the stability of the floor slab component during transportation can be effectively improved. After folding, the steel reinforcement structure 3 is placed between the central concrete slab 1 and the side concrete slab 2, reducing the damage caused by the protrusion of the steel reinforcement structure 3 and reducing damage to the floor slab component.

For example, in the claims, any of the claimed embodiments can be used in any combination.
