Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically to an adjustable prefabricated composite panel. Background Technology

[0002] In the construction industry, the stability and reliability of floor slab structures are crucial. Traditional floor slab structures typically consist of precast concrete slabs with embedded steel bars or ribs to enhance their structural strength. During installation, slabs are usually fixed using methods such as welding or bolting. This traditional floor slab structure is widely used in various construction projects, including residential, commercial, and public facilities. However, because the floor slab structure is relatively fixed, it lacks flexibility in adjusting and adapting to different building requirements. For example, adjusting a traditional floor slab structure can be difficult when adapting to different loads or design changes, and challenges may arise during installation and maintenance. Adjusting the floor slab during construction often requires hammering or bending the steel bars to complete the connection, which can reduce the reliability of the steel bars and increase the complexity and cost of future maintenance. Traditional floor slab structures may also be ineffective in handling irregular building shapes, as any necessary adjustments may involve complex construction processes, further increasing construction time and costs. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable prefabricated composite slab, which allows for flexible adjustment of the reinforcing steel bars in the slab to match the connecting reinforcing steel bars of the external structure, thereby improving the flexibility and adaptability of the slab.

[0004] The objective of this invention can be achieved through the following technical solutions.

[0005] An adjustable prefabricated composite slab includes a floor slab with a plurality of parallel first ribs and second ribs. The second ribs are located in the middle of the floor slab, and the plurality of first ribs are symmetrically arranged on both sides of the second ribs. The floor slab also contains a plurality of parallel adjustable reinforcing bar assemblies, which are perpendicular to the second ribs. Each adjustable reinforcing bar assembly includes two rotating cylinders symmetrically arranged on both sides of the second ribs and adjustable reinforcing bars disposed in each rotating cylinder. The diameter of the adjustable reinforcing bars is smaller than the inner diameter of the rotating cylinders. A rotating shaft is provided on each adjustable reinforcing bar, which is eccentrically connected to the rotating cylinders. Alternatively, the adjustable reinforcing bars can be rotated along the inner wall of the rotating cylinders to achieve position adjustment. Any adjustable reinforcing bar on the floor slab can be adjusted to match the connecting reinforcing bars of the external structure, eliminating the need to hammer or bend the reinforcing bars of the floor slab and avoiding a reduction in the reliability of the floor slab reinforcing bars during construction.

[0006] A plastic block is provided at one end of the rotating cylinder located inside the floor slab. The position of the plastic block corresponds to that of the second rib. The second rib has a fixing hole for the hammer block to extend into, so that the lower end of the hammer block can extend into the gap between the two plastic blocks of the rotating cylinder on both sides of the second rib. The plastic block is provided with a structure that matches the end shape of the adjustable reinforcing bar, such as a groove. When the hammer block is inserted between the two plastic blocks, the plastic block is moved by force and engages with the end of the corresponding adjustable reinforcing bar to limit the position of the adjustable reinforcing bar. The hammer block and the plastic block constitute the fixing component of the adjustable reinforcing bar. The fixing component is provided to pre-position the adjustable reinforcing bar, that is, to temporarily fix the reinforcing bar in the floor slab and prevent the adjustable reinforcing bar from shifting position.

[0007] The rotating cylinder is provided with a first grouting port for grouting, and a second grouting port corresponding to the position of the first grouting port is opened on the floor slab. The first and second grouting ports are used to cast the adjustable steel bars and the concrete of the floor slab into an integral structure after the floor slab is connected.

[0008] The present invention also has the following preferred designs:

[0009] The rotating cylinder of the present invention is composed of multiple cylinder sections connected by connecting rods, and the first injection port is formed between adjacent cylinder sections. Furthermore, the spacing between the multiple first injection ports can be uniformly set. The present invention sets multiple first injection ports, which can effectively shorten the length of the injection channel, thereby reducing the injection difficulty and improving the fixing strength after grouting.

[0010] The floor slab of the present invention is further provided with I-shaped connecting bars inside. The connecting bars are arranged alternately with the adjustable steel reinforcement assembly. The I-shaped connecting bars are used to compensate for the reduction in floor slab strength caused by the gaps in the floor slab due to the setting of the adjustable steel reinforcement assembly and the fixing assembly, and can further enhance the stability of the floor slab.

[0011] The connecting rib of the present invention is disposed in the middle of the floor slab, corresponding to the position of the second rib.

[0012] The two ends of the connecting rib of the present invention are connected to the rotating cylinder to achieve pre-fixation of the rotating cylinder.

[0013] The rotating cylinder of the present invention has a rotation limiting groove inside that matches the rotating shaft on the adjustable reinforcing bar. In one feasible embodiment, a retaining ring can be pre-set inside the rotating cylinder to form a rotation limiting groove, so that the rotating shaft of the adjustable reinforcing bar is rotatably installed in the rotation limiting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention enables flexible adjustment of floor slab reinforcement, improving the flexibility and adaptability of the floor slab: the adjustable reinforcement can be rotated along the inner wall of the rotating cylinder to achieve position adjustment, and any adjustable reinforcement on the floor slab can be adjusted to match the connecting reinforcement of the external structure, eliminating the need to knock or bend the floor slab reinforcement, thus avoiding reducing the reliability of the floor slab reinforcement during construction.

[0016] 2. The first and second ribs of the present invention can enhance the overall structural strength of the floor slab, and their layout also facilitates the installation and fixing of adjustable steel reinforcement components and fixing components.

[0017] 3. The fixing component set in this invention pre-positions the adjustable reinforcing bars, which can temporarily fix the reinforcing bars in the floor slab and prevent the adjustable reinforcing bars from shifting position.

[0018] 4. The rotating cylinder of the present invention is provided with multiple first injection ports, which can effectively shorten the length of the injection channel, thereby reducing the injection difficulty and improving the fixing strength after grouting. Attached Figure Description

It is understandable that those skilled in the art may omit certain well-known structures and their descriptions in the drawings.

[0029] To fully understand this invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by this invention. Optional embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0030] Please see Figures 1 to 8 An adjustable prefabricated composite slab includes a floor slab 1 with multiple parallel first ribs 2 and second ribs 3. The second ribs 3 are located in the middle of the floor slab 1, and the multiple first ribs 2 are symmetrically arranged on both sides of the second ribs 3. The floor slab 1 also contains multiple parallel adjustable steel reinforcement assemblies 4, which are perpendicular to the second ribs 3. Each adjustable steel reinforcement assembly 4 includes two symmetrically arranged rotating cylinders 41 on both sides of the second ribs 3 and adjustable steel bars 42 arranged in each rotating cylinder 41. The diameter of the adjustable steel bars 42 is smaller than the inner diameter of the rotating cylinder 41. A rotating shaft 43 is provided on the adjustable steel bars 42, which are eccentrically connected to the rotating cylinder 41 through the rotating shaft 43. In a preferred embodiment, the adjustable steel bars 42 can be rotated along the inner wall of the rotating cylinder 41 to achieve position adjustment. Any adjustable steel bar 42 on the floor slab 1 can be adjusted to match the connecting steel bars of the external structure, eliminating the need to hammer or bend the steel bars of the floor slab 1 and avoiding reducing the reliability of the floor slab steel bars during construction.

[0031] See Figure 8A plastic block 52 is provided at one end of the rotating cylinder 41 located inside the floor slab 1. The position of the plastic block 52 corresponds to that of the second rib plate 3. The second rib plate 3 has a fixing hole for the striking block 51 to extend into, so that the lower end of the striking block 51 can extend into the gap between the plastic blocks 52 of the two rotating cylinders 41 on both sides of the second rib plate 3. The plastic block 52 is provided with a structure that matches the end shape of the adjustable steel bar 42, such as a groove. When the striking block 51 is inserted between the two plastic blocks 52, the plastic block 52 is moved by force and engages with the end of the corresponding adjustable steel bar 42 to limit the position of the adjustable steel bar 42. The striking block 51 and the plastic block 52 constitute the fixing component 5 of the adjustable steel bar 42. The fixing component 5 is provided to pre-position the adjustable steel bar 42, that is, to temporarily fix the steel bar in the floor slab 1 and prevent the adjustable steel bar 42 from moving.

[0032] The rotating cylinder 41 is provided with a first grouting port 44 for grouting, and a second grouting port 6 is provided on the floor slab 1 corresponding to the position of the first grouting port 44. The first grouting port 44 and the second grouting port 6 are provided to cast the adjustable steel bar 42 and the concrete of the floor slab 1 into an integral structure after the floor slab 1 is connected.

[0033] In one embodiment, the rotating cylinder 41 is composed of multiple cylinder sections connected by connecting rods 45, and a first injection port 44 is formed between adjacent cylinder sections. Furthermore, the spacing between the multiple first injection ports 44 can be uniformly set. Setting multiple first injection ports 44 can effectively shorten the length of the injection channel, thereby reducing the injection difficulty and improving the fixing strength after grouting.

[0034] In one embodiment, the interior of the floor slab 1 is further provided with I-shaped connecting bars 7, such as... Figure 6 As shown, the connecting bars 7 and the adjustable steel reinforcement assembly 4 are arranged alternately. The I-shaped connecting bars 7 are used to compensate for the reduction in floor strength caused by the gaps in the floor slab 1 due to the setting of the adjustable steel reinforcement assembly 4 and the fixing assembly 5, which can further enhance the stability of the floor slab.

[0035] In one embodiment, the connecting rib 7 is located in the middle of the floor slab 1, corresponding to the position of the second rib 3.

[0036] In one embodiment, the two ends 7a of the connecting rib 7 are connected to the rotating cylinder 41 to achieve pre-fixation of the rotating cylinder 41.

[0037] In one embodiment, such as Figure 4 As shown, the interior of the rotating cylinder 41 is provided with a rotation limiting groove that matches the rotating shaft 43 on the adjustable reinforcing bar 42. As a feasible implementation, a retaining ring can be pre-set inside the rotating cylinder 41 to form a rotation limiting groove, so that the rotating shaft 43 of the adjustable reinforcing bar 42 can be rotatably installed in the rotation limiting groove.

[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
