Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, specifically to a formwork system and construction method for a multi-layer beam. Background Technology

[0002] A mezzanine beam (also known as a floor joist or intermediate beam) is a structural component commonly used in multi-story buildings, bridges, and industrial plants. Located between floors or different levels of a structure, it serves as a connection and support, effectively transferring loads and enhancing the overall stiffness and stability of the structure. The design and construction of mezzanine beams are crucial in the construction process, directly impacting the safety and durability of the building.

[0003] During the construction of the project, when constructing the cast-in-place concrete structure, interlayer beams may be encountered. These beams are characterized by a large gap between the two layers of beams, with no structural slabs on both sides of the beams, making them relatively independent. Conventional formwork methods cannot be used for construction, resulting in significant construction difficulties.

[0004] Therefore, this invention proposes a formwork support system and construction method for interlayer beams to solve the above problems. Summary of the Invention

[0038] The support system includes: a support pole 6, the surface of the support pole 6 is threaded with a thread 7, a lifting rod 8 is screwed onto the thread 7, a mounting plate 9 is provided at one end of the support pole 6, an I-beam 10 is connected to the mounting plate 9 by bolts, the end face of the I-beam 10 is fixed to the side of the wall 11 by limit bolts, and a concrete beam 12 is provided on the side of the wall 11.

[0039] Through the support system, I-beams 10, beam side formwork and other structures, this formwork system adopts a fixed aluminum alloy formwork 1, the lower support is independently supported by support poles 6, and temporary support is set at the floor level with I-beams 10. This support system has the characteristics of simple and quick formwork, small space required for the frame, small material consumption, easy dismantling, environmental protection, construction safety and good structural forming effect.

[0040] Example 2

[0041] Based on Embodiment 1, in order to facilitate the connection between the I-beam 10 and the aluminum alloy template 1, a support pole 6 and a lifting pole 8 are provided. During the pouring of the concrete beam 12, a threaded pipe 13 is provided inside. Multiple sets of threaded pipes 13 are provided, and the multiple sets of threaded pipes 13 are arranged linearly at equal intervals about the surface of the concrete beam 12. The concrete beam 12 is poured between the walls 11 of the two floors. A limit bearing 14 is provided at the bottom of the lifting pole 8. A positioning nut 15 is provided on the surface of the limit bearing 14. A positioning screw 16 is provided at the bottom of the positioning nut 15. The positioning screw 16 can be screwed into the threaded pipe 13. The positioning screw 16 can be rotated through the positioning nut 15. A rotating nut 17 is sleeved on the surface of the lifting pole 8. A threaded groove 18 is opened on the end face of the lifting pole 8.

[0042] In use, the positioning screw 16 can be rotated by the positioning nut 15, so that the positioning screw 16 can be easily screwed into the threaded tube 13 and the second threaded tube 22. The setting of the limit bearing 14 can prevent the lifting rod 8 from rotating when the positioning screw 16 is rotated. Thus, the lifting rod 8 and the support column 6 can cooperate to support the bottom of the I-beam 10 and the aluminum alloy template 1. The setting of the threaded tube 13 and the second threaded tube 22 can be easily connected to the support column 6.

[0043] To facilitate adjustment of the support pole 6 and the lifting pole 8, a threaded groove 18 is provided. The support pole 6 can be screwed into the threaded groove 18 using a thread 7. A limit nut 20 is screwed onto the thread 7. The mounting plate 9 is fixedly connected to the end face of the support pole 6. The limit nut 20 can rotate up and down along the thread 7. The surface of the I-beam 10 is provided with a pull ring 19. There are two sets of pull rings 19, which are symmetrically distributed about the center line of the long side of the side of the I-beam 10. The mounting plate 9 can be fixedly connected to the upper and lower surfaces of the I-beam 10 using bolts.

[0044] During use, the height of the support pole 6 and the lifting rod 8 can be adjusted by the screw displacement of the support pole 6 in the threaded groove 18, which facilitates the support of I-beams 10 and aluminum alloy templates 1 of different heights. The setting of the limit nut 20 can increase the stability of the support pole 6 and avoid the problem of one end of the support pole 6 moving down in the threaded groove 18 due to excessive pressure on the thread 7 and the threaded groove 18. The setting of the pull ring 19 also facilitates the hoisting of the I-beam 10.

[0045] Example 3

[0046] Based on Embodiment 2, a movable plate 3 is provided to facilitate the installation of pull tabs 5 of different widths. A placement groove 21 is provided at the bottom of the aluminum alloy template 1, and a second threaded tube 22 is installed within the placement groove 21. One end of the positioning screw 16 can be screwed into the second threaded tube 22. A limiting port 23 is provided at the bottom of the movable port 2. Multiple sets of movable ports 2 are provided, and these sets are arranged linearly and equidistantly on the side of the aluminum alloy template 1. The movable plate 3 has a square plate-like structure and can be displaced within the movable port 2. The bottom of the movable plate 3... The part is provided with a limit screw 24, and a fixing nut 25 is screwed onto the surface of the limit screw 24. The positioning frame 4 is fixedly connected to the end face of the moving plate 3. There are two sets of positioning frames 4, which are symmetrically distributed about the pull plate 5. There are multiple sets of pull plates 5, which are linearly arranged at equal intervals about the aluminum alloy template 1. The surface of the pull plate 5 is provided with positioning angle steel 26. The positioning angle steel 26 can be fixed to other structures by mounting bolts. There are two sets of positioning angle steel 26, and both sets of positioning angle steel 26 are fixed to the surface of the pull plate 5.

[0047] In use, the fixing nut 25 can be loosened first, allowing the movable plate 3 to move within the movable opening 2. This allows for adjustment of the spacing between the two sets of positioning frames 4, facilitating the fixing and installation of pull tabs 5 of different widths. Then, the fixing nut 25 can be tightened to fix the movable plate 3. The setting of the limiting opening 23 also prevents the movable plate 3 from detaching from the movable opening 2. The setting of the positioning angle steel 26 allows for fixed connection with the surrounding formwork system, ensuring the stability of the beam side formwork.

[0048] A construction method for a formwork system for a mezzanine beam includes the following steps:

[0049] S1: Construction preparation: First, pour concrete beam 12. After pouring, fix I-beam 10 with bolts.

[0050] S2: Support system installation: Install support poles 6 according to the layout and positioning, so that the support poles 6 and the lifting poles 8 cooperate to support the bottom of the I-beam 10 and the bottom of the aluminum alloy formwork 1;

[0051] S3: Install beam side formwork: Use tie rods 5 and positioning frames 4 to reinforce the beam side formwork. After installation, use positioning angle steel 26 to fix it to the surrounding formwork system to ensure the stability of the beam side formwork.
