Technical Field

[0001] The utility model relates to the technical field of building reinforcement, in particular to a novel steel formwork fixing structure. Background Art

[0002] Nowadays, cities are developing rapidly and changing with each passing day. Due to various usage requirements of users, more and more residential and public buildings are facing changes in internal room functions, renovation of facade decoration, and insufficient load-bearing capacity of some components due to their age. Therefore, designers are required to make reasonable reinforcement and repair plans in a timely manner according to the latest specifications and functional demands of the construction unit.

[0003] In the prior art, when reinforcing building components, the method of anchoring and tying, wooden formwork and wooden formwork is usually used. A scaffolding is built at the bottom to support the formwork, and a pouring port is reserved to pour grouting material. However, there are still the following shortcomings: the traditional wooden planks and scaffolding are used together, the construction cost is high, and it is not easy to reuse.

[0010] Preferably, rubber plugs are provided at both ends of the U-shaped groove.

[0011] By adopting the above technical solution and providing a rubber plug, foreign matter cannot enter the interior of the U-shaped groove, thereby avoiding affecting the accuracy of the calibration result.

[0012] Preferably, a pouring hole is opened on one side of the steel plate, and a check grouting valve is arranged inside the pouring hole.

[0013] By adopting the above technical solution and setting a check grouting valve, it is convenient for construction workers to carry out grouting operations while effectively preventing mud backflow, thereby improving practicality.

[0014] Preferably, a plurality of fixing blocks are fixedly mounted on one side of the steel plate, a pulling rod is fixedly mounted between two of the fixing blocks, and a rubber pad is fixedly mounted on the outer wall of the pulling rod.

[0015] By adopting the above technical solution and setting a pulling rod, construction workers can pull the steel plate apart by dragging the pulling rod when demoulding the steel plate after reinforcement is completed, thereby reducing the difficulty of demoulding. By setting a rubber pad, the friction force on the surface of the pulling rod can be increased to avoid hand slippage.

[0016] Preferably, one side of the steel plate is coated with a silicon dioxide layer.

[0017] By adopting the above technical solution and providing a silicon dioxide layer, the hardness, wear resistance, chemical stability and corrosion resistance of the steel plate surface can be effectively improved, thereby increasing the service life of the steel plate.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] When in use, construction workers can use high-strength bolts to connect the angle steel located above to the floor slab, and connect the angle steel located below to the bottom of the beam, thereby fixing the steel plate to the outside of the building that needs to be reinforced. Multiple steel plates can be spliced ​​together by connecting the angle irons, which reduces the cost and construction period of using scaffolding to build wooden formwork in the original plan. The steel plate has higher strength, reduces the risk of formwork expansion, and can be disassembled and reused after construction is completed, which is more practical.

[0020] By setting up a U-shaped groove, the staff can place the U-shaped groove on top of the connecting plate and observe the liquid level inside the U-shaped groove through the acrylic observation plate to detect whether the placement of the steel plate is qualified and avoid tilting. By setting up a rubber plug, foreign debris cannot enter the interior of the U-shaped groove to avoid affecting the accuracy of the calibration effect. By setting up a check grouting valve, while facilitating the grouting operation for construction personnel, it is effectively prevented from slurry backflow and improves practicality. By setting up a pull rod, after the reinforcement is completed, when the steel plate is demoulded, the construction personnel can pull the steel plate apart by dragging the pull rod, thereby reducing the difficulty of demoulding. By setting up a rubber pad, the friction force on the surface of the pull rod can be increased to avoid hand slippage. By setting up a silica layer, the hardness, wear resistance, chemical stability and corrosion resistance of the steel plate surface can be effectively improved, thereby increasing the service life of the steel plate.
