Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a steel formwork assembly for repairing concrete expansion joints in building engineering. Background Technology

[0002] Concrete expansion joint repair is a common maintenance project in construction engineering. It mainly addresses problems such as cracking, damage, and leakage of concrete at expansion joints caused by temperature changes, structural settlement, etc. The concrete expansion joint repair process mainly includes base surface treatment, interface treatment, formwork fixing, concrete pouring, curing, and formwork removal. Among them, the formwork fixing is done with special formwork, which is fixed on both sides of the expansion joint to ensure that the formwork is tightly attached to the base surface to prevent grout leakage during concrete pouring.

[0003] During the concrete pouring and solidification process, the concrete structures on both sides may experience slight displacement. At this time, the poured concrete may develop problems such as cracks and spalling. Therefore, a steel formwork assembly for repairing concrete expansion joints in construction engineering is needed. This assembly can limit the concrete structures on both sides through a fixed structure, preventing slight displacement of the concrete structures on both sides during the concrete pouring and solidification process, and improving the quality of concrete expansion joint repair.

It includes two fixed plates 2 positioned on top of two bases 1, with two symmetrical sealing strip mounting brackets 3 positioned between the two bases 1. Four symmetrical fixing bolts 4 are threaded through the top of each fixed plate 2, passing through the sealing strip mounting brackets 3 and connected to the fixed plates 2 by threads. Two symmetrical threaded sleeves 5 are fixedly connected to the top of each fixed plate 2, with a fixing screw 6 passing through the inner cavity of each threaded sleeve 5. Four symmetrical limiting sleeves 7 are threadedly connected to the surface of each fixing screw 6. A gasket 8 is fixedly connected to the side of each threaded sleeve 5 away from the fixed plate 2. An opening 9 is provided on each opposite side of the two fixed plates 2, and the inner cavity of the opening 9 is... A fixed rod 10 is provided, and a threaded rod 11 is provided through the top of the fixed rod 10. The fixed rod 10 and the threaded rod 11 are threadedly connected. The bottom of the threaded rod 11 extends through to the bottom of the fixed rod 10 and is rotatably connected to a pressure plate 12. A torsion block 13 is fixedly connected to the top of the threaded rod 11. Two symmetrical torsion bars are fixedly connected to the surface of the torsion block 13. Through the cooperation of the threaded rod 11 and the pressure plate 12, the torsion block 13 is rotated to make the threaded rod 11 threadedly connected to the fixed rod 10, so that the pressure plate 12 moves downward and fits against the top of the two symmetrical sealing strip mounting brackets 3. This prevents the height of the sealing strip mounting brackets 3 from shifting during concrete pouring and improves the stability of the sealing strip mounting brackets 3. The fixed rod 10 slides in the inner cavity of the two symmetrical openings 9. Example 2

[0022] Figure 1-4 This invention illustrates a steel formwork assembly for repairing concrete expansion joints in a building construction project, comprising two fixed plates 2 mounted on top of two bases 1. Two symmetrical reinforcing plates 14 are fixedly connected to the top of the fixed plates 2. The reinforcing plates 14 are triangular, the fixed plates 2 are L-shaped, the surfaces of the limiting sleeves 7 are hexagonal, the openings 9 are square frames, and the fixing rods 10 are rectangular strips. Two symmetrical sealing strip mounting brackets 3 are provided between the two bases 1. Four symmetrical fixing bolts 4 are threaded through the top of the fixed plates 2, passing through the sealing strip mounting brackets 3 and threadedly connected to the fixed plates 2.

Openings 9 are provided on opposite sides of the two fixed plates 2, and fixing rods 10 are provided inside the openings 9, sliding within the two symmetrical openings 9.

[0023] Working principle: When using this utility model, the user fixes two symmetrical fixing plates 2 to the top of two symmetrical bases 1 using fixing bolts 4, so that two fixing screws 6 pass through four symmetrical threaded sleeves 5. By rotating the limiting sleeves 7, the two limiting sleeves 7 on the surface of the fixing screws 6 are respectively attached to the gaskets 8 and the fixing plates 2, so that the fixing rods 10 pass through two symmetrical openings 9. This allows the fixing plates 2, fixing screws 6, and limiting sleeves 7 to limit the two symmetrical bases 1, preventing slight displacement of the concrete structure on both sides during the concrete pouring and solidification process, thus improving the quality of concrete expansion joint repair. Through the cooperation of the threaded rods 11 and pressure plates 12, rotating the torsion block 13 causes the threaded rods 11 to be threadedly connected to the fixing rods 10, causing the pressure plates 12 to move downwards and attach to the top of the two symmetrical sealing strip mounting frames 3, preventing the sealing strip mounting frames 3 from shifting in height during concrete pouring, thus improving the stability of the sealing strip mounting frames 3.

[0024] In summary, this steel formwork assembly for repairing concrete expansion joints in construction engineering uses fixing bolts 4 to fix two symmetrical fixing plates 2 to the top of two symmetrical bases 1, allowing two symmetrical fixing screws 6 to pass through four symmetrical threaded sleeves 5. By rotating the limiting sleeves 7, the two limiting sleeves 7 respectively come into contact with the gaskets 8 and the fixing plates 2. This achieves the effect of limiting the concrete structure on both sides through the fixing structure, preventing slight displacement of the concrete structure on both sides during the concrete pouring and solidification process, and improving the quality of concrete expansion joint repair.
