Description

Technical fields:

[0001] This utility model belongs to the field of building construction technology, and in particular relates to the field of building formwork construction technology. Specifically, it is a tie-rod portable fixed modular steel formwork. Background technology:

[0002] Prefabricated steel formwork is widely used in formwork engineering construction due to its advantages such as easy assembly and disassembly, long service life, and high construction efficiency. Traditional steel formwork, when reinforced with tie rods, requires welding threaded ends to the tie rods inside the concrete slab, and then locking them with traditional "3"-shaped fasteners. However, in large-volume concrete slabs, the demand for formwork and tie rods is enormous, and each tie rod needs to be welded before reinforcement can be achieved, greatly limiting construction progress and increasing labor costs. Furthermore, welding across the entire slab cannot guarantee the welding quality of each tie rod. After concrete pouring, the threaded ends of the tie rods need to be cut and reused, but the number of reuses is limited, requiring repeated purchases, significantly increasing construction costs. Utility model content:

[0003] The purpose of this utility model is to improve the existing loosely assembled steel formwork and realize a simple and quick way to fix the formwork reinforcement during the formwork construction process.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

The tie rod hole 7 at the center of the fixed base 1 has an interlocking device 2 at a 120° angle on its wall. The interlocking device 2 and clamping gear 3 engage in a toothed mesh. Rotating the clamping gear 3 allows the interlocking device 2 to engage the tie rod passing through the tie rod hole 7. The locking device 4 and fixing device 5 are both located in the pre-reserved slot of the fixed base 1, which can limit the movement of the tie rod, and the limiting function can be released manually.

[0031] When using this portable fixed modular steel formwork for formwork construction, the modular steel formwork 6 is installed in place using traditional methods. Then, the tie rods 8 to be fixed are passed through the tie rod holes 7. The clamping gear 3 is rotated to engage the tie rods 8 with the interlocking device 2, ensuring the interlocking force meets the formwork reinforcement requirements. The locking device 4 is then engaged in the groove of the interlocking device 2. After ensuring the locking device 4 limits the interlocking device 2 to the required position, the fixing device 5 is inserted to prevent loosening of the locking device 4, thus completing the installation and fixing of the tie rods 8. After the concrete is poured, the fixing device 5 is removed to release the limiting and fixing of the formwork reinforcement. Lifting the locking device 4 and rotating the clamping gear 3 allows for the unloading and removal of the tie rods 8. After construction, this modular steel formwork 8 can be reused like existing modular steel formwork.
