[0002] Building formwork is an indispensable building material in construction engineering. It is a temporary support structure that bears the self-weight of the building formwork and the external loads acting on it. There are many formwork specifications, but the types of materials are limited. Traditional formworks mainly include wooden formworks, steel formworks, aluminum alloy formworks, plastic composite formworks, etc. Among them, wooden formworks are prone to water absorption, steel formworks are not corrosion-resistant, aluminum formworks are expensive, and plastic composite formworks have low strength, etc.

[0003] Moreover, traditional building formworks are single rectangular formworks with a relatively simple overall structure. When fixing them, it is inconvenient and requires two people to operate. One person supports and holds, and the other person fixes with screws. This is not only troublesome, but also when manually holding, it is easy to misalign and skew, requiring rework, which increases the operation difficulty.

[0004] Therefore, it is necessary to design a novel composite building formwork with high strength, precise fixing, and fast and stable positioning. Utility Model Content

[0005] Based on this, in view of the deficiencies of traditional building formworks, it is necessary to propose a novel composite building formwork that can quickly complete the installation and fixing of the building formwork and the initial positioning of the building formwork.

[0006] This application provides a novel composite building formwork, which includes a composite base plate and a formwork connection device. The composite base plate is made of multiple layers of composite formworks. The composite base plate includes a contact surface and a support surface. The formwork connection device is fixed on the support surface;

[0007] The formwork connection device includes a connection bracket, a left connection end, and a right connection end. The connection bracket is arranged in the middle of the support surface. The left connection end is fixed at the left end of the support surface, and the right connection end is fixed at the right end of the support surface. The two ends of the connection bracket are respectively fixedly connected to the left connection end and the right connection end;

[0008] The left connection end is provided with a convex strip, and the right connection end is provided with a connection card slot for snap-fitting with the convex strip. Between two adjacent composite base plates, the convex strip on one composite base plate is snap-fitted into the connection card slot on the other composite base plate.

[0009] Preferably, the connection bracket includes a support main rod, and a plurality of reinforcing rods are also arranged on the support main rod.

[0010] Preferably, the reinforcing rods are arranged in parallel at equal intervals.

[0011] Preferably, a support device is further provided on the connecting bracket, and the support device is used to fix the connecting bracket to the site.

[0013] Preferably, a compression-resistant plate is further provided on the L-shaped support plate, and a plurality of mounting holes are provided at the lower end of the L-shaped support plate.

[0014] Preferably, the composite substrate includes a core layer and reinforcing layers provided on both sides of the intermediate layer, and adhesive layers are provided between the core layer and the two reinforcing layers.

[0015] Preferably, the material of the core layer is one of poplar, eucalyptus or pine.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] As Figures 1 to 6 shown, the present application provides a new type of composite building formwork for quickly fixing the composite building formwork in a suitable position to facilitate subsequent cement pouring. The advantages of the present utility model are quick fixation, accurate position adjustment, single-person quick installation without assistance, and high structural strength of the material, which can be waterproof and recycled.

[0035] As Figures 1-2 shown, in an embodiment of the present application

[0036] A new type of composite building formwork includes a composite base plate 1 and a formwork connection device 2. The composite base plate 1 is the main material, and its overall shape is rectangular. In construction, it is mainly used to maintain a specific shape to support cement pouring until completion. To improve the overall strength of the composite base plate 1, the composite base plate 1 in the present utility model is made of a multi-layer composite formwork.

[0037] Specifically, as Figures 5-6 shown; the composite base plate 1 includes a core layer 11 and reinforcing layers 12 arranged on both sides of the intermediate layer. Adhesive layers 13 are arranged between the core layer 11 and the two reinforcing layers 12.

[0039] The core layer 11 mainly plays a filling role, so relatively common wood materials are used. The main material is the reinforcing layer 12, which plays a role in increasing strength and protecting against water.

[0040] Specifically, as Figure 6As shown: The reinforcing layer 12 of the present utility model is composed of more than 2 unidirectional tape layers 120, with at least two layers provided.

[0044] A rib 221 is provided on the left connecting end 22, and a connecting slot 231 for snap-fitting with the rib 221 is provided on the right connecting end 23. Between two adjacent composite substrates 1, the rib 221 on one composite substrate 1 is snap-fitted into the connecting slot 231 on the other composite substrate 1, and multiple composite substrates 1 are sequentially connected together through the rib 221 and the connecting slot 231.

[0045] The connecting bracket 21 includes a main support rod 211, and a plurality of reinforcing rods 212 are further provided on the main support rod 211. The reinforcing rods 212 are arranged in parallel at equal intervals. By providing the main support rod 211 and multiple reinforcing rods 212, the strength of the composite substrate 1 can be further increased.

[0046] In order to enable the composite substrate 1 to quickly maintain stability with the ground and play a preliminary supporting role, a support device 3 is provided. The support device 3 is also provided on the connecting bracket 21. The support device 3 is used to fix the connecting bracket 21 on the site. Connecting holes 210 are provided at the bottom ends of the reinforcing rods 212. The support device 3 includes a connecting column 31 and an L-shaped support plate 32, and the connecting column 31 is snap-fitted into the connecting hole 210.

[0047] A pressure-resistant plate 33 is further provided on the L-shaped support plate 32, and a plurality of mounting holes 34 are provided at the lower end of the L-shaped support plate 32.

By improving the material composition of the substrate, using wood as the core layer, the materials are easily available and the cost is low. Through the setting of the strengthening layer, not only the problems of easy water absorption and damage of the wooden formwork are solved, ensuring the smoothness of the plate surface, but also the wood is strengthened and protected. Moreover, the strengthening layer belongs to a fiber-reinforced thermoplastic composite material and can be recycled repeatedly itself. Through the introduction of the thermoplastic adhesion layer 13, not only can the strengthening layer and the core layer be bonded together, but according to the state of the building formwork, the strengthening layer and the core layer can be separated by a rolling process to recycle the core layer repeatedly and increase the number of times the formwork is used. By setting the support device, it can be quickly installed on the formwork connection device to provide support for the composite substrate at the bottom.
