[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] The present application relates to a modular formwork assembly for a prefabricated composite beam, the modular formwork assembly comprising a beam formwork 100, a first partition 200 and a second partition 300, the beam formwork 100, the first partition 200 and the second partition 300 are all made of steel, the first partition 200 is arranged on the side of the beam formwork 100, the second partition 300 and the first partition 200 are arranged on the same side of the beam formwork 100, the second partition 300 is arranged along a first direction parallel to the first partition 200, and the second partition 300 is arranged along a second direction perpendicular to the first direction and spaced apart from the first partition 200.

[0026] Furthermore, the modular formwork assembly includes two third partitions 400, which are arranged on the side of the beam formwork 100 where the first partition 200 and the second partition 300 are located, and the modular formwork assembly also includes a limit seat 600, through which the third partition 400 is installed on the side of the beam formwork 100. The two third partitions 400 are respectively configured with at least one limit seat 600.

[0027] In conjunction with the accompanying drawings, the third partition 400 is arranged parallel to the second direction, and the two third partitions 400 are arranged at intervals along the first direction. The first partition 200, the second partition 300 and the two third partitions 400 are enclosed on the side of the beam formwork 100 to form a rectangular casting space, and the first ordinary concrete is poured into the casting space, and the pouring depth is determined according to the design size of the beam.

[0028] It should be noted that the dimension parallel to the first direction is the height of the cast beam. According to the height of the beam, the user selects the first partitions 200 and the second partitions 300 of corresponding quantity or corresponding size to cast precast beams of different lengths, thereby improving the applicability of the combined formwork assembly.

[0029] After the first ordinary concrete pouring is completed, the distance between the two third partitions 400 is increased to allow for the second high performance concrete pouring. Specifically, the position of the limit seat 600 on the beam template 100 is adjustable along the first direction so that the distance between the two third partitions 400 is adjustable, thereby pouring beams of different heights.

[0030] The combined formwork assembly includes a beam cover plate 500, which is used to be arranged at the top of the pouring space and connected to the second partition plate 300 and the third partition plate 400. It should be noted that during the first ordinary concrete pouring, the combined formwork assembly is not provided with the beam cover plate 500, and the structure formed by the first ordinary concrete pouring has a gap from the installation displacement where the beam cover plate 500 is located. During the second high-performance concrete pouring, the combined formwork assembly is provided with the beam cover plate 500, and the combined formwork assembly is erected by rotating the combined formwork assembly along an axis parallel to the first direction, and the end where the second partition plate 300 is located is located at the bottom of the combined formwork assembly, and the end where the first partition plate 200 is located is located at the top of the combined formwork assembly. The first partition plate 200 is removed, and high-performance concrete is injected from the end where the original first partition plate 200 is located.

[0031] As an embodiment, the combined formwork assembly includes at least two connecting rods 700, which are arranged parallel to the second direction, and are spaced apart along the first direction. The two ends of the connecting rod 700 are respectively connected to the first partition 200 and the second partition 300 to keep the positions of the first partition 200 and the second partition 300 fixed.

[0032] Furthermore, the two ends of the connecting rod 700 pass through the first partition 200 and the second partition 300 respectively, and the two ends of the connecting rod 700 fix the first partition 200 and the second partition 300 respectively through the locking piece 710. The locking piece 710 is fixedly connected to the connecting rod 700 and presses the outer side surface of the first partition 200 or the second partition 300 so that the first partition 200 and the second partition 300 can play a shaping role when ordinary concrete is injected for pouring.

[0033] In some examples, the locking member 710 is threadedly connected to the connecting rod 700. Specifically, an end of the connecting rod 700 is provided with an external thread, and the locking member 710 is provided with a threaded hole.

[0034] As an embodiment, a steel section is provided at the lower part of the first partition 200, and the side of the steel section abuts against the end of the third partition 400. In conjunction with the drawings, the steel section is provided as an I-shaped steel section to improve the structural strength of the first partition 200. Furthermore, the wing plate on the outer side of the steel section is extended and widened for installation with the connecting rod 700.

[0035] As an embodiment, a steel section is provided at the lower part of the second partition 300, and the side of the steel section abuts against the end of the third partition 400. In conjunction with the drawings, the section bar is provided as an I-shaped steel section to improve the structural strength of the second partition 300. Furthermore, the wing plate on the outer side of the steel section is extended and widened for installation with the connecting rod 700.

[0036] Furthermore, before the second high-performance concrete pouring, the beam cap 500 is connected to the steel of the second partition 300 and the third partition 400 by bolts or screws, and the beam cap 500 is provided with a plurality of mounting holes near the side. It is understandable that the mounting holes are used to arrange bolts or screws for easy disassembly and assembly.

[0037] As an implementation mode, the second partition plate 300 is connected to the beam formwork 100 to enhance the structural strength of the second partition plate 300. Specifically, both ends of the second partition plate 300 are connected to the beam formwork 100 by screws or bolts.

[0038] In conjunction with the drawings, the second partition plate 300 has mounting portions 320 extending parallel to the first direction at both ends thereof, and the mounting portions 320 are provided with mounting holes for arranging bolts or screws. Further, the second partition plate 300 has mounting portions 320 extending at both ends of the wing plate of the steel section.

[0039] As an implementation mode, the limit seat 600 is installed with the beam formwork 100 by means of bolts or screws, so that the limit seat 600 is fixedly installed on the side of the beam formwork 100 after the position is adjusted, and is convenient for disassembly and assembly.

[0040] In conjunction with the accompanying drawings, the limit seat 600 is provided with an adjustment groove 610, which is arranged parallel to the first direction, and the limit seat 600 is installed on the beam template 100 by means of bolts or screws penetrating the adjustment groove 610. It can be understood that the limit seat 600 uses the adjustment groove 610 as a guide groove, so that the position can be easily adjusted along the first direction, thereby adjusting the spacing of the third partition plate 400.

[0041] The limiting seat 600 has two wing plates and a connecting plate located between the two wing plates. The adjusting groove 610 is arranged on the connecting plate. One end of the wing plate is used to connect to the third partition plate 400 .

[0042] Regarding the position adjustment of the limit seat 600, at least one alternative design is available: at least two mounting holes are arranged in the limit seat 600 parallel to the first direction and spaced apart from each other. By arranging bolts or screws in the mounting holes at different positions, the position adjustment of the limit seat 600 along the first direction can be achieved.

[0043] In some examples, the limiting seat 600 abuts against the side surface of the third partition plate 400, and the limiting seat 600 is connected to the third partition plate 400 by screws or bolts, so that the position of the third partition plate 400 is fixed and it is convenient for disassembly and assembly.

[0044] As an embodiment, a support member 310 is provided on the side of the second partition 300 facing away from the first partition 200. When the modular formwork assembly is flipped over to stand up the modular formwork assembly and the second partition 300 is located at the bottom, the support member 310 is used to support the modular formwork assembly so that the modular formwork assembly remains in an upright state, thereby improving the balance of the modular formwork assembly when standing upright.

[0045] The support member 310 is configured as a steel section or an angle steel.

[0046] The content of the casting method in the present application is described in detail below in conjunction with specific embodiments. It should be noted that the following description is only an illustrative description and is not a specific limitation to the present application.

[0047] The user fixes the first partition plate 200, the second partition plate 300 and the third partition plate 400 to the side of the beam formwork 100 to form a rectangular pouring space, and performs the first ordinary concrete pouring.

[0048] The user disassembles the connecting rod 700 and the first partition 200, increases the spacing of the third partition 400, fixes the beam cover 500 to the second partition 300 and the third partition 400, erects the combined formwork assembly, and moves the solidified ordinary concrete structure to the middle position so that there is a gap between the ordinary concrete structure and the beam cover 500, the beam formwork 100 and the third partition 400.

[0049] The second high-performance concrete pouring is carried out from the end of the top of the modular formwork assembly where the original first partition 200 is located, and the high-performance concrete wraps the side of the ordinary concrete structure to form a composite beam of ordinary concrete and high-performance concrete.

[0050] It should be noted that the modular formwork assembly prefabricates beams of different heights by adjusting the spacing of the third partitions 400, and the modular formwork assembly can be reused, which improves efficiency, reduces material loss, and reduces costs. The modular formwork assembly uses bolts or screws and other structures for fixing and installing, which saves the process of removing the formwork, reduces the use of steel bars for fixing, and reduces the consumption cost of steel bars.
