[0021] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 3 As shown, this embodiment provides an aluminum-plastic combined building formwork (hereinafter referred to as the building formwork) for cooperating in completing the shaping and pouring of concrete.

[0024] The building formwork 100 of this embodiment includes a plastic formwork 1 for casting and a supporting frame for rigidly supporting the plastic formwork 1. The supporting frame is an aluminum frame. The plastic formwork 1 has a casting surface 11 for casting and molding. The supporting frame is assembled on the side of the plastic formwork 1 away from the casting surface 11. Specifically, the supporting frame includes a first reinforcing rib 3 and a second reinforcing rib 2 for rigidly supporting the plastic formwork 1. The first reinforcing rib 3 and the second reinforcing rib 2 are both rigid aluminum reinforcing ribs. The plastic formwork 1 and the first reinforcing rib 3 are arranged at a distance, the second reinforcing rib 2 is arranged between the plastic formwork 1 and the first reinforcing rib 3, and the first reinforcing rib 3 and the second reinforcing rib 2 are arranged crosswise to form a rigid support for the plastic formwork 1. Specifically, the plastic formwork 1 can be cut, and the shape of the plastic formwork 1 can be arbitrarily cut and spliced ​​according to different engineering needs to ensure that the shape of the building formwork 100 is easy to process.

[0025] In this embodiment, the aluminum alloy skeleton formed by the first reinforcing rib 3 and the second reinforcing rib 2 can not only ensure its high mechanical strength, but also can be reused, that is, it can be recycled many times, thereby ensuring low average use cost and low carbon emission reduction, and can also ensure short construction period, convenient construction, high efficiency, good stability, high bearing capacity, no construction waste on site, and strong construction standards and versatility.

[0026] Compared with the steel formwork in the prior art, the plastic formwork 1 made of plastic material has the advantages of light weight, high strength, impact resistance, wear resistance, smooth or bright surface, no water absorption, no deformation, no mildew, no stratification and no blistering when immersed in water, stable plate size, long service life, acid and alkali resistance, and corrosion resistance, thereby ensuring good casting and molding effect, and is convenient for daily use and storage, and does not require anti-corrosion treatment and will not pollute the concrete.

[0027] In addition, the use of plastic formwork 1 can achieve environmental protection and economy. Its service life is 8 to 15 times that of traditional wooden formwork, and its turnover number of uses can reach more than 50 times. Moreover, the plastic formwork 1 can be recycled and reused after being scrapped, so it has strong economic and social benefits.

[0028] By using the plastic formwork 1 and a plurality of first reinforcing ribs 3 and second reinforcing ribs 2 made of aluminum alloy as an integral composite plate structure, it has the advantages of high mechanical strength, light weight, reasonable force, convenient construction and high turnover rate, and ensures good project quality. It can also realize concrete pouring only by manual labor, thereby eliminating the need for lifting equipment to participate in concrete pouring.

[0029] More specifically, a plurality of first reinforcing ribs 3 and second reinforcing ribs 2 are fixed to the plastic template 1 at intervals from each other, and the first reinforcing ribs 3 and the second reinforcing ribs 2 are perpendicular to each other to achieve stable support, while effectively reducing the use of aluminum alloy, that is, further achieving weight reduction.

[0030] like Figure 4 As shown, a tensile member 4 for resisting the tensile force formed when pouring concrete is arranged between the plastic formwork 1 and the first reinforcing rib 3. The tensile member 4 is detachably passed through the plastic formwork 1 and the first reinforcing rib 3 and inserted into the concrete. Specifically, the tensile member 4 is a hook-shaped round steel and includes a threaded portion and a fixed connection portion for fixing an anchor bar 10 to the concrete. The fixed connection portion protrudes from the pouring surface 11 of the plastic formwork 1, and the threaded portion is movably passed through the plastic formwork 1 and the first reinforcing rib 3, and then forms a threaded connection with a bolt 7 abutting against the side of the first reinforcing rib 3 away from the plastic formwork 1, so as to realize the detachable fastening of the tensile member 4 to the building formwork 100.

[0031] like Figure 4 As shown, when the building formwork 100 needs to be installed, the building formwork 100 is firstly sleeved on the anchor bar 10 of the solidified concrete 12, and the washers and the threaded connection between the bolts 7 and the threaded parts of the tensile members 4 are used to achieve preliminary fixation, and then the fixed connection parts of the multiple tensile members 4 are respectively welded to the anchor bar 10 of the solidified concrete 12 through the inclined tension bars 9 to complete the installation of the building formwork 100.

[0032] After the concrete pouring is completed, it is only necessary to unscrew all the bolts 7, and then pull the entire building formwork 100 out of the tensile member 4. At this time, the tensile member 4 is fixed in the solidified concrete 12 and does not need to be recovered. Such a building formwork 100 is easy to disassemble and does not require a release agent. That is, it can be demoulded by simply tapping the building formwork 100. Moreover, the disassembly is convenient and quick, which is conducive to organizing the construction and effectively speeding up the construction progress.

[0033] like Figure 1As shown, the building formwork 100 of this embodiment also includes a rotatable connector 5 for splicing. The mechanical strength of the first reinforcing rib 3 is greater than the mechanical strength of the second reinforcing rib 2. The rotatable connector 5 is arranged on the first reinforcing rib 3 located at the outermost side. The specific rotatable connector 5 is a fastener, which is rotatably assembled on the first reinforcing rib 3, and the fastener has a buckle portion for buckling the positioning bolt 6 of the building formwork 100. By fastening the buckle portion of the fastener of one of the building formworks 100 to the positioning bolt 6 of the adjacent building formwork 100, two adjacent building formworks 100 can be spliced ​​into one, so that the installation structure is simple and convenient.

[0034] In this specific embodiment, the facade size of a single building formwork 100 is a square plate of 1.50m×3.15m, a plurality of first reinforcing ribs 3 are arranged along the long direction of the plastic formwork 1, a plurality of second reinforcing ribs 2 are arranged along the wide direction of the plastic formwork 1, and the second reinforcing ribs 2 are first fixed to the side of the plastic formwork 1 away from the casting surface 11, and then the first reinforcing ribs 3 are fixed to the second reinforcing ribs 2. In this way, the weight of a single building formwork 100 is only about 55kg, which is much less than the weight of a steel formwork, and a plurality of building formworks 100 can be assembled into building formwork components of various sizes with a total width of at least 3m, and only two people are needed to complete the on-site assembly of the building formwork components, and no lifting equipment is required to avoid safety hazards when the lifting equipment is operated.

[0035] In addition, the specific installation method of the building template 100 of this embodiment is as follows:

[0036] like Figure 4 As shown, first, the assembled building template 100 is inserted into the anchor bar 10 of the solidified concrete 12 at the bottom through the preset through hole, and then tightened and fixed by the bolt 7 (i.e., sleeve bolt), and then the working platform 8 for the installation personnel to stand is installed on the building template 100; when the building template 100 is initially fixed, the inclined tie bar 9 is welded between the fixed connection part of the tension member 4 and the anchor bar 10 of the solidified concrete 12 to further tighten the building template 100, and the bolt 7 can also be manually adjusted to further fine-tune the verticality of the building template 100, or fine-tune the building template 100 according to the structural edge line position required by the design; when the warehouse surface of the concrete warehouse is prepared and passed the acceptance, the next step is to pour the warehouse concrete, and pre-embed a new anchor bar 10 on the top of the unsolidified concrete 13, so as to weld the tension member 4 of the next building template 100 to this anchor bar 10 through the new inclined tie bar 9.

[0037] After the poured concrete solidifies, the building template 100 is first removed, and then the residual mortar of the removed building template 100 is promptly scraped off, and then a higher building template 100 is installed on the top of the solidified concrete to achieve the following Figure 5The building formwork 100 is shown as being raised layer by layer.

[0038] In short, the building template 100 can be installed in any combination through various assembly methods such as nailing, drilling, longitudinal and transverse assembly, and no additional support and reinforcement structure is required to ensure simple installation between each structure.

[0039] Of course, when multiple building templates 100 need to be removed, the building templates 100 on the bottom layer are removed first, and then the building templates 100 on the upper layer are removed.
