Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0026] In the description of the present application, it is understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation of the present application.
[0027] Please refer to Figure 1 The present application is a bridge wet joint formwork, which comprises a bottom mould composed of a first formwork 1 and a second formwork 2 which are independent of each other and can be installed cooperatively when used, and the upper surface of the bottom mould abuts against the bottom side of a prefabricated component 100 after installation.
[0028] In the assembled state, such as Figure 2 The upper surfaces of the first template 1 and the second template 2 are coplanar. The first template 1 includes a template body A10, and the second template 2 includes a template body B20. Both the first template 1 and the second template 2 are rectangular wooden boards, and also include two support beams 4 supporting the two precast components 100. The two support beams 4 are parallel to each other, and a hanger 3 passes through each end of the support beam 4. The bottom end of the hanger 3 is provided with a threaded section. A threaded sleeve A15 that is threadedly connected to the threaded section of the hanger 3 is fixed on the template body A10, and a threaded sleeve B24 that is threadedly connected to the threaded section of the hanger 3 is fixed on the template body B20.
[0029] In order to facilitate the installation of the first template 1 and the second template 2 against the bottom side of the precast component 100, that is, after the first template 1 and the second template 2 are connected to the support beam 4 by the hanger 3, it is necessary to control the first template 1 and the second template 2 to move upward. Therefore, the present application has support bolts 41 threadedly connected to both ends of the support beam 4, and pads 42 are connected to the ends of the support bolts 41. In the installation state, the two pads 42 at both ends of the support beam 4 support the upper surfaces of the two precast components 100 respectively.
[0030] In use, to facilitate the assembly of the first template 1 and the second template 2, and to improve the bonding strength at their joints, preventing separation and tilting of the first template 1 and the second template 2; for example Figures 3-7 In this technical solution, three positioning posts 12 are provided on the bottom side of the first template 1, and a support plate 21 is connected to the bottom side of the second template 2. One side of the support plate 21 protrudes from one edge of the second template 2, and the upper surface of the support plate 21 is provided with an insertion hole 22 that mates with the positioning posts 12. The bottom side of the first template 1 is also provided with a positioning boss 11. When the first template 1 and the second template 2 are in the assembled state, the positioning posts 12 are inserted into the insertion hole 22, and one side of the support plate 21 abuts against one side of the positioning boss 11.
[0031] During assembly, when the first template 1 and the second template 2 are controlled to move horizontally / vertically by the two lifting rods 3, the first template 1 and the second template 2 are first controlled to move horizontally until they are against the positioning boss 11 on one side of the support plate 21. Then, the first template 1 and the second template 2 are controlled to move horizontally and vertically, and the positioning column 12 is controlled to be inserted into the insertion hole 22. Then, the lifting rods 3 are controlled to pass through the support beam 4, and the support beam 4 is supported on the upper surface of the two precast components 100 by the support bolts 41 and the pads 42. At this time, the two sides of the upper surface of the bottom mold are respectively in close contact with the bottom side of the two precast components 100 with gaps.
[0032] Meanwhile, to facilitate control during use, the first template 1 and the second template 2 pass through the gap formed by the two precast components 100 and move below the precast component 100, this utility model provides a through hole A17 at each end of the template body A10 and a through hole B28 at each end of the template body B20. That is, during use, after passing ropes through the through holes A17 and B28, the first template 1 and the second template 2 are controlled to pass through the gap formed by the two precast components 100 using a hanging method. After controlling the first template 1 and the second template 2 to be horizontal using ropes, a hanging rod 3 is threaded onto the threaded sleeves A15 and B24, and a plastic sleeve 31 is fitted on the outside of the hanging rod 3. Then, after controlling the support beam 4 to install the hanging rod 3, the rope is removed from the through holes A17 and B28. It can be known that in actual operation, protruding reinforcing bars are provided on the side wall of the precast component 100. Figure 1 (not shown in the image), and the length of the reinforcing bar is 2 / 3 of the 100mm gap width between the two precast components.
[0033] Meanwhile, based on the above, in order to facilitate the installation of the hanger rod 3 using the support beam 4 and to keep the support beam 4 and hanger rod 3 fixed in position after installation, a fixing sleeve 32 is provided at the top of the hanger rod 3. The fixing sleeve 32 is provided with a locking bolt 33 whose end abuts against the hanger rod 3, and after installation, the bottom end of the fixing sleeve 32 abuts against the upper surface of the support beam 4.
[0034] During use, grout needs to be injected into the space formed by the bottom mold and the two precast components 100. To prevent some grout from leaking out from the gap between the bottom mold and the precast components 100 due to excessive gaps, this application provides a groove A16 along the length of one edge side of the upper surface of the template body A10, and a deformation layer A14 is provided in the groove A16; a groove B27 along the length of one edge side of the upper surface of the template body B20 is provided, and a deformation layer B26 is provided in the groove B27; in the natural state, the upper surface of the deformation layer A14 is higher than the upper surface of the template body A10, and the upper surface of the deformation layer B26 is higher than the upper surface of the template body B20; and both the deformation layer A14 and the deformation layer B26 can be filled with cotton cloth or sponge.
[0035] To improve structural strength, multiple support beams 23 are fixed on one side of the support plate 21, and the support beams 23 are fixed to the bottom side of the template body B20.
