Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present invention provides a building formwork 200 including a housing 100, and referring to fig. 1, the housing 100 may be configured, for example, in a substantially rectangular parallelepiped shape having substantially an opening. The housing 100 includes a plurality of fiber-reinforced layers, and adjacent layers of the plurality of fiber-reinforced layers are connected to each other. A plurality of fiber reinforced layers may be arranged side by side in the thickness direction of the housing 100.

It will be appreciated that each of the plurality of fibrous reinforcement layers comprises a substrate and fibres arranged within the substrate, wherein the fibres of each layer are arranged unidirectionally, i.e. the fibres of each layer extend in the same direction.

The fibers may be selected as continuous fibers and the substrate may be selected as a resin substrate or any other suitable material. The resin may be a thermoplastic resin. The fibers of each layer cover the entire housing 100, i.e., cover the respective side walls of the housing 100 and the base wall connected to the respective side walls, which may also be referred to as the bottom wall for the illustrated placement.

In particular, the plurality of fibrous reinforcement layers includes a base layer and a reinforcement layer. Each of the base layer and the reinforcing layer has unidirectionally arranged fibers, and the arrangement direction of the fibers is different between different layers.

Specifically, referring to fig. 1, the base layer includes a first base layer 101 and a second base layer 102, the first base layer 101 being provided with first base fibers, and the second base layer 102 being provided with second base fibers. The reinforcement layers comprise a first reinforcement layer 103 and a second reinforcement layer 104 arranged in groups, the first reinforcement layer 103 being provided with first reinforcement fibres and the second reinforcement layer 104 being provided with second reinforcement fibres.

It is noted that in the partial cross-section shown in fig. 1, the fibers in each layer are schematically shown in a plurality of straight lines, and the arrangement of the different layers and their fibers are shown simultaneously for ease of understanding, however, it is understood that the cross-sections of the layers are actually in different vertical planes.

Wherein the first base fibers extend in a first base direction D11 and the second base fibers extend in a second base direction D12. The first reinforcement fibers extend in a first reinforcement direction D21 and the second reinforcement fibers extend in a second reinforcement direction D22. The first base direction D11, the second base direction D12, the first reinforcement direction D21 and the second reinforcement direction D22 are different from each other. In other words, the angles at which the fibers of the respective layers are disposed are different from each other.

Due to the arrangement of the fibers in each layer, a multi-layer multi-angle fiber reinforced structure is formed, the fiber reinforced structure can better bear forces in multiple directions, and when the building formwork 200 bears pressure or shear force, the shape of the building formwork 200 can be maintained, so that the service life of the building formwork 200 is prolonged. Moreover, the fibers increase the strength of the building formwork 200, ensure the safety during construction to a certain extent, and avoid construction accidents caused by the quality problem of the formwork.

The direction of the arrangement of the fibres should have a certain mechanical basis, and with continued reference to fig. 1, fig. 1 shows an exemplary embodiment in which the first base direction D11 may be at an angle of 90 degrees to the second base direction D12, i.e. the first base direction D11 is perpendicular to the second base direction D12. The first reinforcement direction D21 and the first base direction D11 have a first included angle, the second reinforcement direction D22 and the first base direction D11 have a second included angle, the first included angle is equal to the second included angle, and further, the included angles of the first reinforcement direction D21 and the second reinforcement direction D22 relative to the second base direction D12 are also equal.

The arrangement is such that the forces between the fibres are uniform during production of the building formwork 200. Specifically, since the included angle between the first base direction D11 and the second base direction D12 is 90 degrees, when the building formwork 200 receives external forces in different directions, the forces borne by the first base fibers and the forces borne by the second base fibers can be balanced with each other. For similar reasons, the forces experienced by the first reinforcing fibers and the forces experienced by the second reinforcing fibers can be balanced with each other. Thus, deformation of the shell 100 due to uneven distribution of the forces experienced between the fibers of the building formwork 200 is avoided.

Alternatively, the first base direction D11 is a horizontal direction and the second base direction D12 is a vertical direction. In other words, the extending direction of the first base fiber is 0 degree, and the extending direction of the second base fiber is 90 degrees. The first included angle and the second included angle may be 40 to 50 degrees, such as 40 degrees, 42 degrees, 44 degrees, 45 degrees, 46 degrees, 48 degrees, 50 degrees, and the like. In other words, the first reinforcing fibers and the second reinforcing fibers are arranged obliquely with respect to the horizontal direction and the vertical direction.

In a preferred embodiment, referring to fig. 1 and 2, the first reinforcing layer 103 and the second reinforcing layer 104 are provided in one set. Thus, in this embodiment, the housing 100 comprises four fibre-reinforced layers. The first base layer 101, the first reinforcing layer 103, the second base layer 102, and the second reinforcing layer 104 are arranged side by side in the thickness direction of the case 100 in this order. As an example, referring to fig. 2, the first foundation layer 101, the first reinforcement layer 103, the second foundation layer 102, and the second reinforcement layer 104 are arranged side by side from the outside to the inside in the thickness direction of the shell 100 in this order. And the first included angle and the second included angle are 45 degrees. It should be noted that fig. 2 uses different patterns for filling only to schematically distinguish the layers, and does not show the arrangement of the fibers.

The building formwork 200 can further include reinforcing ribs 110, the reinforcing ribs 110 extending along the height direction of the housing 100 and being spaced apart from each other on the inner surface of the housing 100.

The building formwork 200 of the present embodiment can be produced by the following steps:

1) Firstly, sequentially putting a first basic fiber with an extension direction of 0 degree, a first reinforcing fiber with an extension direction of 45 degrees, a second basic fiber with an extension direction of 90 degrees and a second reinforcing fiber with an extension direction of 135 degrees into a mold of a building formwork 200 from outside to inside along the thickness direction of a shell 100;

2) Secondly, injecting the plastic base material into a mould shell mould, and forming the shell 100 through hot melting and compounding;

3) Finally, the formwork reinforcement is injected to the housing 100, and the mold is closed and pressed to form the novel building formwork 200 with the reinforcement 110 integrated with the housing 100.

In this way, the building formwork 200 with the 4-layer fiber reinforced layer structure can be obtained, the stress in the shell 100 is uniform, the strength of the building formwork 200 is high, the building formwork is easy to fix and not easy to run, the use of constructors is convenient, the efficiency can be improved, the building formwork can be repeatedly used for many times and is difficult to damage, and the durability is strong. Alternatively, the base material of the fiber-reinforced layer and the base material of the reinforcing ribs are made of the same material, for example, the same resin material, i.e., the same plastic base material as the formwork rib material, can be the same resin, for example, a thermoplastic resin.

In other embodiments, not shown, the first reinforcement layer 103 and the second reinforcement layer 104 are arranged in more than two groups (e.g. four groups), i.e. a building formwork 200 with 6 or more layers of fiber reinforcement layers is obtained. Wherein the first reinforcement fibres in different groups extend in different first reinforcement directions D21 and the second reinforcement fibres extend in different second reinforcement directions D22. And, the first angle and the second angle are preferably 40 to 50 degrees.

With this arrangement, the fibers in four or more directions can better withstand forces in more directions, can further increase the strength of the building formwork 200, and can be applied to use situations requiring higher requirements.

Referring to fig. 3, the reinforcing rib 110 has a flocculent structure inside, i.e., a plurality of reinforcing fibers with different directions and interlaced with each other are arranged, and the arrangement of the fibers can also enhance the strength of the reinforcing rib 110, so that the strength of the building formwork 200 can be enhanced.
