[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Reference below Figure 1-Figure 2 A precast beam formwork 100 according to an embodiment of the present invention is described.

[0026] like Figure 1 As shown, the precast beam formwork 100 according to the embodiment of the utility model includes a side form 10, a side form truss 20 and an adjusting member 30. The side form truss 20 is arranged on the outside of the side form 10 for fixing the side form 10. The side form truss 20 has a mounting position 214, and the mounting position 214 is provided with a rotatable adjusting member 30. The adjusting member 30 is rotated to adjust the height of the precast beam formwork 100 from the ground.

[0027] Specifically, the precast beam template 100 has two inclined and oppositely arranged side templates 10, both of which are inclined upward and outward, and the outsides of the two side templates 10 are provided with side template trusses 20, which are used to support and fix the side templates 10. The side template trusses 20 are arranged on the ground, and an adjustment member 30 is also arranged between the side template trusses 20 and the ground, and the adjustment member 30 can adjust the height of the precast beam template 100 from the ground. The adjustment member 30 is arranged vertically, one end of which is fixed on the ground, and the other end is connected to the mounting position 214 of the side template truss 20. By rotating the adjustment member 30, the height adjustment of the precast beam template 100 can be achieved. In practice, during the prefabrication of box beams, a plurality of gaskets are usually placed under the template to adjust the height, and the accuracy of the height adjustment is low.

[0028] According to the prefabricated beam formwork 100 of the embodiment of the utility model, the height of the side formwork truss 20 can be adjusted by installing the adjusting member 30 under the side formwork truss 20 and rotating the adjusting member 30, thereby adjusting the height of the prefabricated beam formwork 100. There is no need to adjust the height of the formwork by laying shims, which improves the accuracy and flexibility of the height adjustment, makes the adjustment more convenient and quick, and improves the prefabrication efficiency of the box beam.

[0029] In some embodiments, the side form truss 20 is composed of multiple groups of frames 21, and the multiple groups of frames 21 are arranged in sequence along the length direction of the side form 10. Since the side form 10 is relatively long, if the side form truss 20 is set as a long truss, it is inconvenient to move it, and it is inconvenient to adjust its position relationship with the side form 10. The side form truss 20 is set to be composed of multiple groups of frames 21, which is convenient for its production and transportation. The multiple groups of frames 21 are easy to assemble and the connection is stable, which can ensure that the multiple groups of frames 21 firmly support the side form 10.

[0030] like Figure 1 As shown, specifically, the frame 21 includes two connecting rods 211 and two columns 212, the connecting rods 211 and the columns 212 are arranged at intervals, the connecting rods 211 cooperate with the outer wall of the side mold 10, and the two connecting rods 211 and the two columns 212 are respectively aligned along the length direction of the side mold 10. The frame 21 also includes a crossbar 213, one end of the crossbar 213 is connected to the connecting rod 211, and the other end of the crossbar 213 is connected to the column 212 opposite to the connecting rod 211. A plurality of crossbars 213 are arranged at intervals along the height direction of the column 212, and the length of the plurality of crossbars 213 decreases as the height of the column 212 increases.

[0031] It should be noted that the two connecting rods 211 are opposite to each other in the length direction of the side mold 10, and the two columns 212 are opposite to each other in the length direction of the side mold 10. The columns 212 are located on the outside of the connecting rods 211. The connecting rods 211 and the columns 212 are opposite to each other. The connecting rods 211 are used to support the side mold 10 and fit the side mold 10. Since the side mold 10 is tilted, the connecting rods 211 are also tilted upward and outward, and the columns 212 are perpendicular to the ground. A plurality of horizontal cross bars 213 are arranged between the connecting rods 211 and the columns 212 opposite to them. The two ends of the cross bars 213 are connected to the connecting rods 211 and the columns 212 respectively. The length of the plurality of cross bars 213 arranged between the connecting rods 211 and the columns 212 gradually decreases from bottom to top, the top cross bar 213 is the shortest, and the bottom cross bar 213 is the longest.

[0032] With this arrangement, the frame 21 has a simple structure and is easy to manufacture. The shape of the connecting rod 211 matches the shape of the side mold 10, and can better support and fix the side mold 10. A plurality of cross bars 213 are arranged along the height direction of the frame 21, and the connecting rods 211 and the columns 212 are respectively connected from the top, middle and bottom, thereby improving the stability of the frame 21.

[0033] In addition, at least a top beam, a middle beam and a bottom beam are connected between the two columns 212 of each frame 21, and at least a top beam, a middle beam and a bottom beam are connected between the two connecting rods 211 of each frame 21, which can further improve the stability of the frame 21.

[0034] like Figure 1 As shown, in some embodiments, each group of frames 21 has at least one group of mounting positions 214, and the bottom ends of one of the columns 212 of the frames 21 and the connecting rod 211 opposite thereto form a group of mounting positions 214, or the mounting positions 214 are formed below the ends of the bottom cross bars 213 of each group of frames 21.

[0035] It should be noted that a group of mounting positions 214 includes two, and an adjusting member 30 is installed at each mounting position 214. The mounting position 214 can be formed at the bottom end of the column 212 and the connecting rod 211 opposite thereto, or can be formed at the bottom surface of the two ends of the bottom cross bar 213. The mounting position 214 is set here so that the adjusting member 30 is in surface contact with the frame 21 to ensure the contact area between the two, which is convenient for the installation and disassembly of the adjusting member 30 and the frame 21, and ensures that the adjusting member 30 effectively lifts the frame 21. At least one group of mounting positions 214 is set in each group of frames 21, and at least two adjusting members 30 can be set on the frame 21 to quickly adjust the height of the frame 21 and ensure the stability of the frame 21.

[0036] like Figure 2 As shown, in some embodiments, the adjusting member 30 has a supporting portion 31 and a telescopic portion 32, the telescopic portion 32 is connected to the supporting portion 31 and is located below the supporting portion 31, the supporting portion 31 is in contact with the mounting position 214, and the telescopic portion 32 is rotated to adjust the height of the supporting portion 31. The telescopic portion 32 has a primary screw 321 and a secondary screw 322, the external thread of the secondary screw 322 cooperates with the internal thread of the primary screw 321, and the upper end of the secondary screw 322 is screwed into the supporting portion 31. The adjusting member 30 also includes a support seat 33, and the lower end of the primary screw 321 is screwed into the support seat 33.

[0037] Specifically, the support seat 33 is located at the bottom of the adjusting member 30 and is in contact with the bottom surface. The telescopic part 32 is constructed as a screw assembly, including a primary screw 321 and a secondary screw 322 arranged in sequence from bottom to top in the height direction. The supporting part 31 is located at the top of the adjusting member 30, and the top surface of the supporting part 31 is fixedly connected to the mounting position 214 of the frame 21. The upper end of the secondary screw 321 is arranged in the supporting part 31, and the support seat 33 is provided with a threaded hole. The lower end of the primary screw 321 is arranged in the threaded hole of the support seat 33. A transmission assembly can also be arranged in the support seat 33. The primary screw 321 is connected to the transmission assembly, and the primary screw 321 is driven to rotate by the transmission assembly. During the rotation process, the primary screw 321 drives the secondary screw 322 to move under the action of the thread, so that the telescopic part 32 is extended or shortened, thereby realizing the function of adjusting the height of the adjusting member 30. The adjusting part 30 may also be provided with an adjusting portion, which may extend out of the supporting seat 33 and may be connected to the primary lead screw 321 , and the adjusting portion may be manually controlled to drive the primary lead screw 321 to rotate.

[0038] With this arrangement, the adjusting member 30 has a simple structure and a simple height adjustment principle. The telescopic portion 32 is extended or shortened by rotating the two-stage lead screw, thereby adjusting the height of the side mold truss 20 connected to the adjusting member 30. This has higher flexibility and facilitates height control.
