Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to an adjustable assembled composite board. Background Art

[0002] In the construction industry, the stability and reliability of floor structures are crucial. Traditional floor structures are usually composed of prefabricated concrete slabs with embedded steel bars or ribs to enhance their structural strength. Floors are usually installed using fixed connections such as welding or bolting. This traditional floor structure is widely used in various construction projects such as residential, commercial buildings and public facilities, but because the floor structure is relatively fixed, the flexibility of the traditional floor to adjust and adapt to different building needs is low. For example, in cases where it is necessary to adapt to different loads or design changes, the adjustment of traditional floor structures may be difficult, and challenges may also be encountered during installation and maintenance. Because the floor needs to be adjusted during construction, the steel bars need to be knocked or bent to complete the connection, which will reduce the reliability of the steel bars and increase the complexity and cost of future maintenance; when encountering irregular building shapes, traditional floor structures may not be able to respond effectively, because the traditional floor structure is fixed, and any necessary adjustments may involve a complex construction process, which will also increase construction time and cost. Summary of the invention

[0003] The object of the present invention is to provide an adjustable assembled composite slab, which can flexibly adjust the steel bars of the floor slab to match the connecting steel bars of the external structure, thereby improving the flexibility and adaptability of the floor slab.

[0004] The purpose of the present invention can be achieved through the following technical solutions.

[0005] An adjustable assembled composite slab comprises a floor slab, wherein the floor slab has a plurality of first ribs and a second ribs parallel to each other, the second ribs are arranged in the middle of the floor slab, and the plurality of first ribs are symmetrically arranged on both sides of the second ribs, and the floor slab is further provided with a plurality of parallel adjustable steel bar assemblies, the adjustable steel bar assemblies are perpendicular to the second ribs, the adjustable steel bar assemblies comprise two rotating cylinders symmetrically arranged on both sides of the second ribs and an adjustable steel bar arranged in each rotating cylinder, the diameter of the adjustable steel bar being smaller than the inner diameter of the rotating cylinder, a rotating shaft being arranged on the adjustable steel bar, and the adjustable steel bar is eccentrically rotatably connected to the rotating cylinder through the rotating shaft, as a possibility, the adjustable steel bar can be rotated along the inner wall of the rotating cylinder to achieve position adjustment, any adjustable steel bar on the floor slab can be adjusted to match the connecting steel bar of the external structure, and it is no longer necessary to knock or bend the steel bars of the floor slab, thereby avoiding reducing the reliability of the steel bars of the floor slab during construction;

[0006] A plastic block is provided at one end of the rotating cylinder located in the floor slab, and the position of the plastic block is corresponding to the second rib plate. A fixing hole for a knocking block to be inserted is provided on the second rib plate, so that the lower end of the knocking block can be inserted into the gap between the two plastic blocks of the rotating cylinder on both sides of the second rib plate. The plastic block is provided with a structure matching the shape of the end of the adjustable steel bar, such as a groove. When the knocking block is inserted between the two plastic blocks, the plastic block is forced to move and fasten and fix with the corresponding end of the adjustable steel bar to achieve the limitation of the adjustable steel bar. The knocking block and the plastic block constitute a fixing component of the adjustable steel bar. The fixing component is set to pre-position the adjustable steel bar, that is, it plays a temporary fixing effect on the steel bars in the floor slab to prevent the adjustable steel bar from moving in position.

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

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

[0010] The interior of the floor slab of the present invention is also provided with I-shaped connecting ribs, which are staggered with the adjustable steel bar assembly. The I-shaped connecting ribs are used to compensate for the problem of reduced floor slab strength caused by gaps in the floor slab due to the provision of the adjustable steel bar assembly and the fixed assembly, thereby further enhancing the stability of the floor slab.

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

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

[0013] The interior of the rotating cylinder of the present invention is provided with a rotation limit groove matching the rotating shaft on the adjustable steel bar. In a feasible implementation manner, a retaining ring can be pre-set inside the rotating cylinder to form a rotation limit groove, so that the rotating shaft of the adjustable steel bar can be rotatably installed in the rotation limit groove.

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

[0015] 1. The present invention realizes the flexible adjustment of the floor slab steel bars, and improves the flexibility and adaptability of the floor slab: the adjustable steel bars can be rotated along the inner wall of the rotating cylinder to realize position adjustment, and any adjustable steel bars on the floor slab can be adjusted to match the connecting steel bars of the external structure, and it is no longer necessary to knock or bend the steel bars of the floor slab, thereby avoiding reducing the reliability of the floor slab steel bars during construction.

[0016] 2. The first ribs and the second ribs of the present invention can not only enhance the overall structural strength of the floor slab, but also facilitate the installation and fixation of the adjustable steel bar assembly and the fixing assembly.

[0017] 3. The fixing assembly provided in the present invention pre-positions the adjustable steel bars, which can temporarily fix the steel bars in the floor slab and prevent the adjustable steel bars from shifting in position.

[0018] 4. The rotating drum of the present invention is provided with a plurality of first pouring ports, which can effectively shorten the length of the pouring channel, thereby reducing the difficulty of pouring, and is beneficial to improving the fixing strength after grouting.
